Description

A power cable take-up

technical field

The utility model relates to a power cable take-up device.

Background technique

The wire and cable products used in the power system mainly include overhead bare wires, bus bars (busbars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber-sheathed cables, overhead insulated cables), branch cables (replacing some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment, etc. During the use of power cables, many common faults will occur, such as mechanical damage, insulation damage, insulation damp, insulation aging and deterioration, overvoltage, cable overheating faults, etc. When the above-mentioned fault occurs in the line, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be checked and analyzed, and then repaired and tested. After the power cable has been in operation for a long time, the above faults will become more and more serious and frequent, and must be replaced according to industry regulations.

At present, since there is no dedicated power cable replacement equipment, when the power system replaces power cables, the old cables are recycled manually, which is time-consuming and laborious, and the work efficiency is very low. Since the old cables cannot be reused after recycling, they are generally treated as waste according to the regulations. Therefore, it is impossible to effectively organize the old cables when recycling the cables. They are randomly gathered or twisted into groups to save labor and save recycling time. In this way, the recovered cable clusters are of different sizes and shapes, which is not only unfavorable for warehouse personnel to check, but also unfavorable for storage. Since waste cables are measured by weight, they need to be weighed and stored in pieces after recycling. The above-mentioned cable clusters are not easy to take and place when weighing, and it is even more difficult to place them, which makes weighing difficult. Due to the large size of the cable clusters, it is easy to scatter The weighing value is inaccurate and inefficient.

Contents of the invention

The technical problem to be solved by the utility model is to aim at the above-mentioned defects, and provide a kind of reasonable structure, which can automatically bundle and wind waste cables. Operable and easy-to-operate power cable take-up.

In order to solve the above-mentioned technical problems, the structural features of this power cable take-up are: it includes a base with a weighing instrument fixed on it, a main frame is installed on the weighing platform of the weighing instrument, and a rotary sleeve arranged vertically in the axial direction is installed on the main frame. The uniform ring at the lower part of the rotary sleeve is provided with a swing arm hinged by a horizontal hinge shaft. The middle part of the swing arm is bent towards the center of the rotary sleeve. A central shaft is inserted in the axial slide of the rotary sleeve. The conical surface of the conical block is evenly distributed with the track corresponding to the swing arm. The middle part of the swing arm is fixed with an extension block extending to the track. The end of the extension block is installed with a fitting that can only move along the track. The main power device for the rotation of the rotary sleeve. The main frame is also equipped with a lifting device that drives the central shaft to move up and down. The base is also equipped with a knife holder corresponding to the cable inlet end on the main frame. The cutting device also includes a start-stop device that controls the start and stop of the main power device and the lifting device.

This power cable take-up realizes the automatic bundling of waste cables through the weighing swing arm winding structure. The bundle is tight, easy to bundle, automatic accurate weighing, automatic throwing, and easy to operate.

The weighing type swing arm winding structure mainly includes a swivel sleeve arranged on the main frame and a central shaft inserted in the swivel sleeve, wherein the lower part of the swivel sleeve is evenly equipped with a plurality of swing arms, so that the lower part of the swivel sleeve is formed. A swing arm ring enclosed by the individual swing arms. The upper end of the swing arm is hinged below the rotary sleeve through a horizontal hinge shaft, so that the swing arm can swing back and forth around the hinge shaft. In this patent, the axis line of the horizontal hinge shaft is tangentially matched with the outer circumference of the rotary sleeve where the horizontal hinge shaft is located, so the plane where the swing track of each swing arm is located is the plane where the swing arm corresponds to the meridian of the rotary sleeve, that is, the swing arm swings The plane where the trajectory is located is distributed in an explosive shape centered on the axis line of the rotary sleeve. For the convenience of description, the outer direction of the rotary sleeve is referred to as the outer, and the axis line of the rotary sleeve is referred to as the inner. In this patent, the middle part of the swing arm protrudes toward the axis of the rotary sleeve as a whole, and the two ends of the swing arm gradually extend away from the axis. That is to say, the middle part of the swing arm bends inward and both ends are smooth outwards. Transitional V shape. In this way, a V-shaped cavity is formed outside the V-shaped swing arm, which is called a V-shaped groove for convenience of description. Because the rotary sleeve is installed vertically according to the axis, in the natural state, the swing arm on the left is in the shape of ">", and the swing arm on the right is in the shape of "<". <" shape. At this time, an annular cavity with a V-shaped cross section is roughly formed on the outside of the swing arm ring. For the convenience of description, it is called a V-shaped ring cavity or a V-shaped ring groove, and the V-shaped ring groove is used for winding and temporarily storing cables. Location.

A central shaft is slidably inserted in the rotary sleeve, and the central shaft can only slide axially along the inner cavity of the rotary sleeve and cannot rotate relative to the rotary sleeve in a circumferential direction. A conical block is fixed at the lower end of the central shaft, and the tip of the conical block is set downward. The conical block has two surfaces, one of which is the top plane, and the middle part of the plane is affixed to the lower end of the central axis. The other surface is the lower conical surface, on which there are evenly distributed tracks corresponding to the swing arms one by one, and the tracks extend vertically upward from the tip of the conical block along the conical surface. The middle part of the swing arm is fixed with an extension block extending toward the track, and the end of the extension block is installed with a fitting that matches the track. The fitting can only slide up and down along the track, so that the central shaft and the swing arm form a transmission through the extension block and the track. cooperation relationship. When the central shaft slides down to the lowest point relative to the rotary sleeve, that is, the downstroke point, the fitting slides along the track to the uppermost end of the track, and at this moment, the extension block also reaches a horizontal state. Since the upper end of the track is inclined outward and the lower end is inclined inward, the fitting reaches the outer stroke point or upper stroke point of its stroke. At this time, the swing arm is pushed outward to the maximum state, that is, the maximum or outward swing of the swing arm. trip point. At this time, the upper end and the lower end of the swing arm ring are arranged correspondingly up and down, and the opening direction of the V-shaped ring groove is horizontally outward, presenting a "><" shape. For the convenience of description, this state is called the winding state or the working state. When the central shaft moves upward from the downstroke point along the rotating sleeve, the fitting also drives the extension block to slide downward from the highest point of the track. Since the upper end of the track is inclined outward and the lower end is inclined inward, the fitting will drive the extension block to move inward, that is, drive the swing arm to swing inward. At this time, the opening direction of the V-ring groove also gradually swings downward with the swing of the swing arm . When the central shaft moves upwards along the inner wall of the rotary sleeve to the highest point, that is, the upstroke point, the matching part slides along the track to the lowest end of the track. Because the upper end of the track is inclined outward and the lower end is inclined inward, the fitting part drives the extension block to slide to the innermost end in the inner and outer direction, that is, the inner stroke point or the lower stroke point of its stroke. Under the pull of the extension block and the matching piece, the swing arm is pulled to the maximum point of inward swing by the conical block or the track, that is, the inner travel point. At this time, the lower half of the V-shaped groove wall reaches a vertical state, and the V-shaped ring groove is in the shape of "┐┌". For the convenience of description, this state is called the throwing state or the idle state.

In this patent, the main frame is fixedly installed on the weighing platform of the weighing apparatus, so all items on the weighing platform can be weighed in real time. Before the electric wire is wound, the weight of all items on the scale is almost constant, that is, the weight of the main frame and the structural components such as the rotating sleeve, central shaft, and swing arm installed on the main frame are all constant. Therefore, in order to measure the weight conveniently, the weighing platform and all the devices on the weighing platform before the cable is wrapped are called the general weighing platform, and the weight of the general weighing platform on the weighing instrument is counted as the zero point of the weighing range. In this way, after the swing arm ring winds the cable, the weight detected by the weighing instrument is the weight of the cable wound on the swing arm ring. Therefore, the weight of the wound cable can be known at the same time during the cable winding process. When the weight of the wound cable reaches the specified weight, it can be stopped immediately. Not only is the weighing convenient and accurate, but also the operation is simple, and one person can operate it, which greatly improves the recovery efficiency.

The main frame is equipped with a main power device that drives the rotary sleeve to rotate, and the main power device is controlled by a start-stop device. In this way, when the waste cable needs to be recycled, one end of the waste cable is pre-wound on the swing arm ring, and then the start-stop device is operated to start the main power device, and the main power device drives the rotating sleeve to rotate, and the swing arm ring starts to continue winding the cable . When the weight of the cable detected by the weighing instrument reaches the requirement, it is only necessary to control the start-stop device to stop the main power device, and the operation is very simple. A knife holder corresponding to the cable inlet end is also installed on the base, and a cutting device for cutting the cable is installed on the knife holder. The main function of the cutting device is to cut the cable, that is, to cut off the cable. After the cables wrapped around the swing arm ring meet the weighing requirements and the machine is shut down, the staff can manipulate the cutting device to cut off the cables, so that a bundle of cables that meet the weight requirements has been wound. Then the staff uses auxiliary ropes to bundle the weighed cables in a circumferential direction to prevent them from being scattered, which makes it easy to move and store. The main frame is also equipped with a lifting device, and the main function of the lifting device is to drive the central shaft to move up and down. When the cable weighs up to the standard and is cut off, the staff can control the lifting device to drive the central shaft up. When the central shaft reaches the upper stroke point, the fittings reach the inner stroke point, and the swing arm ring reaches the material throwing state at this time. After the bundled cable loses the clamping and limiting function of the V-shaped ring groove, it will automatically fall to the weighing platform under the action of gravity, and it can be dragged away. The operation is very simple. In this way, a bundle of cables meeting the weighing standard is arranged, and the above-mentioned process can be repeated to continue winding, weighing, and bundling cables. The process is similar and will not be described in detail.

As an improvement, a sub-frame spaced apart from the main frame is installed on the base, a sub-main frame is fixed on the sub-frame, a slide rail is provided on the sub-frame, and a sub-slave frame that slides to the sub-main frame is installed on the slide rail , the auxiliary driving gear is installed on the auxiliary main frame through the auxiliary main shaft, and the upper ring of the outer circumference of the auxiliary driving gear is provided with the auxiliary main semi-arc ring groove matching with the cable, and also includes the auxiliary driven gear installed on the auxiliary slave frame through the auxiliary slave shaft Gears, the upper ring of the secondary driven gear is provided with a secondary slave semi-arc ring groove that matches the cable and corresponds to the sub-master semi-arc ring groove, and is installed between the sub-frame and the sub-slave The driving gear elastically presses and meshes with the auxiliary spring, the groove walls of the auxiliary main half-arc ring groove and the auxiliary slave half-arc ring groove are evenly distributed with embossed patterns, and the auxiliary motor that drives the auxiliary driving gear to rotate is installed on the auxiliary main frame. The line speed of the auxiliary main semi-arc ring groove to stir the cable is slightly faster than the line speed of the rotating sleeve winding cable.

The sub-main frame is fixedly installed on the sub-frame, so the two are fixedly connected integral structures. The sub-slave frame is installed on the sub-frame through the slide rail, so the sub-slave frame can slide on the sub-frame along the slide rail, so the sub-slave frame and the sub-frame are in a relative sliding fit relationship. On the sub-frame, the slide rail is extended toward the sub-main frame, so when the sub-slave frame slides along the slide rail, the sub-slave frame also moves toward the sub-main frame or moves away from the sub-main frame. Sub-main frame is equipped with sub-main shaft, sub-drive gear is installed on sub-main shaft, so sub-drive gear can rotate around its axis line. The auxiliary motor that drives the auxiliary driving gear to rotate is also installed on the auxiliary main frame, so the auxiliary driving gear can be driven to rotate by connecting the auxiliary motor power supply. Second slave shaft is installed on the auxiliary slave frame, auxiliary driven gear is installed on the auxiliary slave shaft, auxiliary driven gear and auxiliary driving gear are meshed with each other, when auxiliary driving gear rotates like this, auxiliary driven gear also can rotate synchronously. A spring is installed between the sub-frame and the sub-slave frame, and the spring pushes the sub-slave frame to move toward the sub-main frame, even if the sub-driven gear and the sub-driving gear are elastically compressed and meshed together. An auxiliary main semi-arc ring groove is provided on the outer peripheral upper ring of the auxiliary driving gear, and the cross section of the auxiliary main semi-arc ring groove is a semicircle matching the outer circumference of the cable. The outer circumference of the auxiliary driven gear is also provided with an auxiliary slave half-arc ring groove. The cross section of the auxiliary slave half-arc ring groove is also a semicircle matching the outer circumference of the cable. set up. In this way, the connecting portion of the auxiliary main half-arc ring groove and the auxiliary slave half-arc ring groove is buckled into a circular cavity corresponding to the outer circumference of the cable, and this circular cavity is the passage that the cable must pass before winding. The groove walls of the auxiliary main half-arc ring groove and auxiliary slave half-arc ring groove are evenly distributed with embossed lines. Force or clamping force to prevent slipping, so that the sub-master semi-arc ring groove and the sub-slave half-arc ring groove can pull the distant cables smoothly and in time and send them to the cable end of the main frame. In this patent, the linear speed of the auxiliary main semi-arc ring groove toggling cable is slightly faster than the linear speed of the rotating sleeve winding cable. It is completed by moving the gear, so that the reverse pulling force of the cable when the swing arm ring is wound is very small and can be ignored, which greatly improves the accuracy of the patent for weighing the wound cable.

As an improvement, a buffer tube is also installed on the base. The buffer tube is arranged in the shape of a crescent in the axial direction, and the buffer tube is in the shape of a round tube with a thicker middle part and gradually thinner ends in the radial direction. The inlet of the buffer tube is arranged correspondingly to the sub-frame. The outlet of the buffer pipe is set corresponding to the swing arm of the main frame.

There are three main functions of the buffer tube. One function is that the two ends of the buffer tube are open and the middle is closed, so it can provide a transmission channel for the cables between the main frame and the sub-frame, and protect the cables from reliable and smooth transmission. The transmission will not be affected by the outside world. Because the line speed of the sub-main semi-arc ring slot to toggle the cable is faster than the line speed of the swing arm ring winding cable, there will be more and more redundancy between the main frame and the sub frame that cannot be wound by the swing arm ring in time. cable. The buffer tube is designed in a meniscus shape with thinner ends and a thicker middle. Its internal space is also wide in the middle and gradually narrows toward both ends. This space design can just provide outward expansion for gradually lengthening redundant cables. space. At the beginning of winding, the redundant cable between the main frame and the sub-frame is the shortest, and the honor cable is located at the shortest axial inner wall of the buffer tube, that is, the axial inner wall closest to the main frame and the sub-frame. In the middle stage of winding cables, there are more and more redundant cables, and the redundant cables will expand outward under their own bending elastic force, that is, move to the longest axial inner wall. In the later stage of winding the cable, the redundant cable will continue to expand outward under the action of its own axial elastic extension tension. At this time, the redundant cable will stick to the longest axial inner wall between the main frame and the sub-frame, that is, the and the axial inner wall farthest from the subframe. When the cable continues to be wound, since the buffer tube is in the shape of a circular tube in the radial direction, more and more redundant cables will be coiled in the inner cavity of the buffer tube under its own axial tension, so that the buffer tube can temporarily store more cable without significant pull on the swing arm ring. Therefore, the second function of the buffer tube is to provide storage space for these redundant cables. The third function of the buffer tube is to separate the cable from the human body, which fundamentally eliminates the accident of the cable winding around the human body, and the risk of the person's clothing and hair being rolled into the swing arm ring, which greatly improves the safety of the operator. safety.

As a preferred embodiment, the lifting device includes an outer sleeve fixed on the main frame, an inner sleeve is inserted in the outer sleeve which can only slide axially along the inner wall of the outer sleeve, and the lower part of the inner cavity of the inner sleeve fits with the central shaft and It can only be rotated and fitted. There is a main internal thread section on the inner wall of the upper part of the inner sleeve, which also includes a transmission shaft that is rotatably installed on the main frame. The transmission gear is installed, and also includes a lifting motor installed on the main frame, and a lifting gear meshed with the transmission gear is installed on the output shaft of the lifting motor.

The lifting device is an electrically driven lifting device, which is powered by a lifting motor. The output shaft of the lifting motor is equipped with a lifting gear, which meshes with the transmission gear, and the transmission gear is fixedly mounted on the transmission shaft that can only rotate axially but cannot move axially, so the transmission shaft will be driven to rotate synchronously when the lifting motor rotates. The lower part of the drive shaft is connected in transmission with the upper part of the inner sleeve, and the lower part of the inner sleeve is connected in transmission with the upper part of the central shaft. The inner sleeve is the core component of the lifting device, and the inner sleeve converts the rotational force of the transmission shaft into the lifting force of the central shaft. The inner sleeve is slidably inserted in the outer sleeve, and the outer sleeve is fixedly installed on the main frame, so the inner sleeve can only slide up and down axially relative to the outer sleeve and cannot rotate relative to the outer sleeve. The upper inner wall of the inner sleeve is provided with a main internal thread section, and the lower part of the transmission shaft is provided with a main external thread section, and the main external thread section and the main internal thread section are screwed together. Therefore, when the transmission shaft that can only rotate in the circumferential direction rotates, the transmission shaft will drive the inner sleeve that can only move axially to move up and down. Because the lower part of the inner cavity of the inner sleeve fits with the central shaft and the two cannot move axially relative to each other, when the inner sleeve moves up and down driven by the transmission shaft, the central shaft must also rise and fall thereupon. Therefore, as long as the positive and negative rotation of the lifting motor is controlled, the lifting of the central shaft can be controlled through the transmission shaft and the inner sleeve, which is very simple. The purpose of matching the lower part of the inner sleeve with the upper part of the central shaft can only rotate in the circumferential direction is to meet the requirement that the central shaft rotates synchronously with the swing arm ring when the cable is wound.

As an implementation, the inner sleeve includes an upper inner sleeve and a lower inner sleeve, the lower inner sleeve includes a fixed lower half inner sleeve and a movable lower half inner sleeve, the fixed lower half inner sleeve is coaxially fixed at the lower end of the upper inner sleeve, The fixed lower half inner sleeve and the movable lower half inner sleeve are correspondingly provided with fixing holes, and fixing bolts are inserted in the fixing holes, bearing grooves are arranged on the upper ring of the inner wall of the lower inner sleeve, and the upper part of the central shaft is installed with a snap-fit fitting for the bearing grooves. upper bearing.

The inner sleeve is mainly composed of three parts, namely the upper inner sleeve, the fixed lower half inner sleeve and the movable lower half inner sleeve. It is separated from the upper inner sleeve. In this inner sleeve, the fixed lower half inner sleeve and the movable lower half inner sleeve are two half sleeves arranged symmetrically along the plane where the axis line of the inner sleeve is located, and the fixed lower half inner sleeve and the movable lower half inner sleeve are correspondingly provided with fixed The fixed hole is inserted with a fixing bolt, and the fixed lower half inner sleeve and the movable lower half inner sleeve are buckled by the fixing bolt to form a lower inner sleeve coaxially arranged with the upper inner sleeve. The inner walls of the fixed lower inner sleeve and the movable lower inner sleeve are provided with bearing grooves corresponding to each other, and the bearing grooves are snap-fitted with the upper bearing outer ring fixedly installed on the upper part of the central shaft. After the fixed lower half inner sleeve and the movable lower half inner sleeve are fixed by fixing bolts, the upper part of the central shaft is fixedly installed to the lower part of the inner sleeve through the upper bearing, and the central shaft and the lower part of the inner sleeve can only be rotated and matched.

As an implementation, the main power device includes a main gear installed on the rotary sleeve, and also includes a main motor installed on the main frame, and a power gear meshing with the main gear is installed on the output shaft of the main motor.

The active power device is an electric drive device, which mainly includes a main motor, a power gear and a main gear. Because the power gear and the main gear are meshed for transmission, when the main motor is powered on, the rotating sleeve will be driven to rotate through the transmission of the power gear and the main gear, and the swing arm ring can be driven to wind the cable.

As an implementation, the cutting device includes two cable anvils fixed at intervals on the knife holder, the cable anvil is provided with a cable groove that is horizontally slidable with the lower half of the cable, and the knife holder is equipped with a cutting lifting device. The lower part of the lifting frame is two arms extending parallel and downward. The lower end of the arm is fixed with a cutting saw blade and a cutting motor that drives the arm shaft to rotate through the rotating arm shaft. There is a vertically arranged pressing sliding sleeve, a pressing slide bar is slidingly inserted in the pressing sliding sleeve, a pressing block is fixed on the lower end of the pressing sliding bar to press up and down with the cable anvil, and a pressing block under the pressing slide bar is fixed with a The pressing positioning rod extending downwards, the cable anvil is provided with a pressing positioning hole that fits up and down with the pressing positioning rod, the upper end of the pressing sliding rod is fixed with a pressing limit block, and the pressing sliding rod between the pressing sliding sleeve and the pressing block There is a pressing spring on it.

In this cutting device, the cable anvil, lifting frame and cutting lifting device are the core structures, and the cable anvil and cutting saw blade are the main parts for completing the cutting of cables. The cable anvil is fixedly installed at the bottom of the knife holder, so the two are fixed and integrated structures. The upper part of the cable anvil is provided with a cable groove that is slidingly matched with the cable. When the swing arm ring winds the cable, the cable slides through the cable groove first, and then is wound on the swing arm ring. The lifting frame is installed on the knife rest above the cable anvil, and the lifting frame is driven by the cutting lifting device to complete the lifting action. The lifting frame bottom is two support arms that are arranged up and down correspondingly with two cable anvils one by one. In this way, when the cutting motor is energized, the cutting saw blade is driven to rotate at a high speed through the support arm shaft. When the cutting lifting device drives the lifting frame down, the high-speed rotating cutting saw blade will cut the cables between the two cable grooves, thereby completing the work of cutting the cables. The rear sides of the two arms are respectively fixed with a vertically arranged pressing sliding sleeve, and a pressing sliding rod freely sliding up and down along the sliding sleeve is inserted in the pressing sliding sleeve. The upper end of the pressing slide bar is fixed with a pressing limit block to prevent the pressing slide bar from slipping downward from the pressing sliding sleeve. The lower end of the pressing slide bar is fixedly provided with a pressing block, which can also prevent the pressing slide bar from slipping upwards from the pressing sliding sleeve. Because the pressing block is set in one-to-one correspondence with the cable anvil, when the lifting frame moves downward, the pressing block also has the function of pressing the cable in the cable groove. A pressing spring is sleeved on the pressing slide bar between the pressing sliding sleeve and the pressing block, and the upper end of the pressing spring is elastically pressed against the lower end surface of the pressing sliding sleeve, and the lower end of the pressing spring is elastically pressed against the upper end surface of the pressing block. Therefore, under the action of its own gravity and the elastic force of the pressing spring, the pressing slide bar slides downwards to the maximum position relative to the pressing sliding sleeve when it is not subjected to other external forces. At this time, the length of the pressing slide bar sliding out of the pressing sliding sleeve is the longest, and the distance that the pressing block descends to the bottom of the cutting saw blade is also the farthest. For the convenience of description, this state is called the natural state or the superior state. When the cable needs to be cut, the lifting frame moves down driven by the cutting lifting device. Because the height of the pressing block is much lower than that of the cutting saw blade in the natural state, the pressing block will touch the cable in the cable groove before the cutting saw blade. Because the cable groove can only accommodate the lower part of the cable, the upper part of the cable is higher than the upper end face of the cable anvil, so when the lifting frame continues to descend, the lifting frame will continue to press the cable in the cable groove downwards by the pressing spring. At this time, the pressing spring is compressed and deformed, and the elastic force of the pressing spring to the pressing block is also increasing. After the cable is under pressure, it will gradually deform radially and fill the entire cable groove, which can play the role of pressing and fixing the cable to the cable anvil, and provides a guarantee for the smooth and reliable cutting of the cable by the cutting saw blade. It basically avoids the phenomenon that the cable rotates and rolls or even rolls out of the cable groove under the force of the cutting saw blade when the saw blade cuts the cable. After the cable is fixed, the cutting lifting device will continue to drive the lifting frame to descend, and the pressing spring will continue to compress and increase the pressing force on the cable. At this time, the cutting saw blade starts to touch the cable and starts to cut the cable. When the cutting and lifting device drives the lifting frame to reach the downstroke point, the pressing spring compresses the shortest, and the pressing and positioning force of the pressing block on the cable reaches the maximum. For convenience of description, this state is called cutting state or lower state. When the lower state is reset to the upper state, a cutting process is over. A pressing positioning rod extending downward is fixed on the pressing block below the pressing slide bar, and a pressing positioning hole is provided on the cable anvil to fit up and down with the pressing positioning rod. Before the pressing block presses the cable, the pressing positioning rod will be inserted into the pressing positioning hole first, which can provide a guiding effect for pressing the pressing block, ensure that the pressing block can be pressed down vertically, and ensure the smooth progress of the pressing positioning. The lower end of the pressing positioning rod is generally set thinner, so that even if there is an insertion error, the pressing positioning rod can be smoothly inserted into the pressing positioning hole.

The cutting and lifting device includes a large sleeve fixed on the tool holder, a small sleeve that can only slide axially along the inner wall of the large sleeve is inserted in the large sleeve, the lower part of the small sleeve is fixedly connected with the upper end of the lifting frame, and the upper inner wall of the small sleeve is There is a lifting internal thread section on the top, and it also includes a lifting transmission shaft installed on the tool rest. The lower section of the lifting transmission shaft is a lifting external thread section that is screwed with the lifting internal thread section. The lifting transmission gear is installed on the lifting transmission shaft. It also includes a cutting and lifting motor installed on the tool holder, and a cutting and lifting gear meshed with the lifting transmission gear is installed on the output shaft of the cutting and lifting motor.

The cutting and lifting device is an electric-driven lifting device, which is powered by a cutting and lifting motor. The output shaft of the cutting and lifting motor is equipped with a cutting and lifting gear, which meshes with the lifting transmission gear. Drive the lifting drive shaft to rotate synchronously. The lower part of the lifting transmission shaft is connected with the upper part of the small sleeve, and the lower part of the small sleeve is fixedly connected with the upper end of the lifting frame. The small sleeve is the core component of the cutting and lifting device, and the small sleeve converts the rotational force of the lifting transmission shaft into the lifting force of the lifting frame. The small sleeve is slidably inserted in the large sleeve, and the large sleeve is fixedly installed on the tool rest, so the small sleeve can only slide up and down axially relative to the large sleeve and cannot rotate relative to the large sleeve. The upper inner wall of the small sleeve is provided with a lifting internal thread section, and the lower part of the lifting drive shaft is provided with a lifting external thread section, and the lifting external thread section and the lifting internal thread section are screwed together. Therefore, when the lifting transmission shaft that can only rotate in the circumferential direction rotates, the lifting transmission shaft will drive the small sleeve that can only move axially to move up and down, that is, the synchronous lifting of the drive lifting frame. Therefore, as long as the forward and reverse rotation of the cutting and lifting motor is controlled, the lifting of the lifting frame can be controlled through the lifting transmission shaft and the small sleeve, which is very simple.

As an implementation manner, the start-stop device includes a main switch installed on the power line of the main power device and a lift switch installed on the power line of the lifting device.

The start and stop of the main power unit can be controlled by operating the main switch, that is, the swing arm ring is controlled to start and stop winding the cable, and the operation is very simple. It is very simple to control the rise and fall of the lifting device by operating the lift switch, that is, to control the rise and fall of the central axis, that is, to control the switching between the winding state and the throwing state.

To sum up, the structure of this power cable take-up is reasonable, it can automatically wrap waste cables in bundles, the bundle is tight, easy to bundle, automatic accurate weighing, automatic throwing, high degree of automation, one person can operate, and the operation simple.

Block 7, the conical surface of the conical block is evenly distributed with the track 8 corresponding to the swing arm, the middle part of the swing arm is fixed with an extension block 9 extending to the track, and the end of the extension block is installed with a fitting 10 that can only move along the track. The main frame is equipped with a main power device 11 that drives the rotary sleeve to rotate. The main frame is also equipped with a lifting device 12 that drives the central shaft to move up and down. The base is also equipped with a knife rest 16 corresponding to the cable 15 inlet end. A cutting device for cutting cables is installed on the top, and a start-stop device for controlling the start and stop of the main power device and the lifting device is also included.

This power cable take-up realizes the automatic bundling of waste cables through the weighing swing arm winding structure. The bundle is tight, easy to bundle, automatic accurate weighing, automatic throwing, and easy to operate.

The weighing type swing arm winding structure mainly includes a swivel sleeve arranged on the main frame and a central shaft inserted in the swivel sleeve, wherein the lower part of the swivel sleeve is evenly equipped with a plurality of swing arms, so that the lower part of the swivel sleeve is formed. A swing arm ring enclosed by the individual swing arms. The upper end of the swing arm is hinged below the rotary sleeve through a horizontal hinge shaft, so that the swing arm can swing back and forth around the hinge shaft. In this patent, the axis line of the horizontal hinge shaft is tangentially matched with the outer circumference of the rotary sleeve where the horizontal hinge shaft is located, so the plane where the swing track of each swing arm is located is the plane where the swing arm corresponds to the meridian of the rotary sleeve, that is, the swing arm swings The plane where the trajectory is located is distributed in an explosive shape centered on the axis line of the rotary sleeve. For the convenience of description, the outer direction of the rotary sleeve is referred to as the outer, and the axis line of the rotary sleeve is referred to as the inner. In this patent, the middle part of the swing arm protrudes toward the axis of the rotary sleeve as a whole, and the two ends of the swing arm gradually extend away from the axis. That is to say, the middle part of the swing arm bends inward and both ends are smooth outwards. Transitional V shape. In this way, a V-shaped cavity is formed outside the V-shaped swing arm, which is called a V-shaped groove for convenience of description. Because the rotary sleeve is installed vertically according to the axis, in the natural state, the swing arm on the left is in the shape of ">", and the swing arm on the right is in the shape of "<". <" shape. At this time, an annular cavity with a V-shaped cross section is roughly formed on the outside of the swing arm ring. For the convenience of description, it is called a V-shaped ring cavity or a V-shaped ring groove, and the V-shaped ring groove is used for winding and temporarily storing cables. Location.

A central shaft is slidably inserted in the rotary sleeve, and the central shaft can only slide axially along the inner cavity of the rotary sleeve and cannot rotate relative to the rotary sleeve in a circumferential direction. A conical block is fixed at the lower end of the central shaft, and the tip of the conical block is set downward. The conical block has two surfaces, one of which is the top plane, and the middle part of the plane is affixed to the lower end of the central axis. The other surface is the lower conical surface, on which there are evenly distributed tracks corresponding to the swing arms one by one, and the tracks extend vertically upward from the tip of the conical block along the conical surface. The middle part of the swing arm is fixed with an extension block extending toward the track, and the end of the extension block is equipped with a fitting that matches the track. The fitting can only slide up and down along the track, so that the central shaft and the swing arm form a transmission through the extension block and the track. cooperation relationship. When the central shaft slides down to the lowest point relative to the rotary sleeve, that is, the downstroke point, the fitting slides along the track to the uppermost end of the track, and at this moment, the extension block also reaches a horizontal state. Since the upper end of the track is inclined outward and the lower end is inclined inward, the fitting reaches the outer stroke point or upper stroke point of its stroke. At this time, the swing arm is pushed outward to the maximum state, that is, the maximum or outward swing of the swing arm. trip point. At this time, the upper end and lower end of the swing arm ring are arranged correspondingly up and down, and the opening direction of the V-shaped ring groove is horizontally outward, presenting a "><" shape. For the convenience of description, this state is called the winding state or the working state. When the central shaft moves upward from the downstroke point along the rotating sleeve, the fitting also drives the extension block to slide downward from the highest point of the track. Since the upper end of the track is inclined outward and the lower end is inclined inward, the fitting will drive the extension block to move inward, that is, drive the swing arm to swing inward. At this time, the opening direction of the V-ring groove also gradually swings downward with the swing of the swing arm . When the central shaft moves upwards along the inner wall of the rotary sleeve to the highest point, that is, the upstroke point, the matching part slides along the track to the lowest end of the track. Because the upper end of the track is inclined outward and the lower end is inclined inward, the fitting part drives the extension block to slide to the innermost end in the inner and outer direction, that is, the inner stroke point or the lower stroke point of its stroke. Under the pull of the extension block and the matching piece, the swing arm is pulled to the maximum point of inward swing by the conical block or the track, that is, the inner travel point. At this time, the lower half of the V-shaped groove wall reaches a vertical state, and the V-shaped ring groove is in the shape of "┐┌". For the convenience of description, this state is called the throwing state or the idle state.

In this patent, the main frame is fixedly installed on the weighing platform of the weighing apparatus, so all items on the weighing platform can be weighed in real time. Before the electric wire is wound, the weight of all items on the scale is almost constant, that is, the weight of the main frame and the structural components such as the rotating sleeve, central shaft, and swing arm installed on the main frame are all constant. Therefore, in order to measure the weight conveniently, the weighing platform and all the devices on the weighing platform before the cable is wrapped are called the general weighing platform, and the weight of the general weighing platform on the weighing instrument is counted as the zero point of the weighing range. In this way, after the swing arm ring winds the cable, the weight detected by the weighing instrument is the weight of the cable wound on the swing arm ring. Therefore, the weight of the wound cable can be known at the same time during the cable winding process. When the weight of the wound cable reaches the specified weight, it can be stopped immediately. Not only is the weighing convenient and accurate, but also the operation is simple, and one person can operate it, which greatly improves the recovery efficiency.

The main frame is equipped with a main power device that drives the rotary sleeve to rotate, and the main power device is controlled by a start-stop device. In this way, when the waste cable needs to be recycled, one end of the waste cable is pre-wound on the swing arm ring, and then the start-stop device is operated to start the main power device, and the main power device drives the rotating sleeve to rotate, and the swing arm ring starts to continue winding the cable . When the weight of the cable detected by the weighing instrument reaches the requirement, it is only necessary to control the start-stop device to stop the main power device, and the operation is very simple. A knife holder corresponding to the cable inlet end is also installed on the base, and a cutting device for cutting the cable is installed on the knife holder. The main function of the cutting device is to cut the cable, that is, to cut off the cable. After the cables wrapped around the swing arm ring meet the weighing requirements and the machine is shut down, the staff can manipulate the cutting device to cut off the cables, so that a bundle of cables that meet the weight requirements has been wound. Then the staff uses auxiliary ropes to bundle the weighed cables in a circumferential direction to prevent them from being scattered, which makes it easy to move and store. The main frame is also equipped with a lifting device, and the main function of the lifting device is to drive the central shaft to move up and down. When the cable weighs up to the standard and is cut off, the staff can control the lifting device to drive the central shaft up. When the central shaft reaches the upper stroke point, the fittings reach the inner stroke point, and the swing arm ring reaches the material throwing state at this time. After the bundled cable loses the clamping and limiting function of the V-shaped ring groove, it will automatically fall to the weighing platform under the action of gravity, and it can be dragged away. The operation is very simple. In this way, a bundle of cables meeting the weighing standard is arranged, and the above-mentioned process can be repeated to continue winding, weighing, and bundling cables. The process is similar and will not be described in detail.

The sub-frame 18 that is arranged at intervals with the main frame is also installed on the base, the sub-frame is fixedly provided with a sub-main frame 25, and a slide rail 26 is provided on the sub-frame, and the sub-slave frame that slides to the sub-main frame is installed on the slide rail 27. The sub-main frame is equipped with a sub-drive gear 20 through a sub-main shaft 19, and a sub-master semi-arc ring groove 21 is provided on the outer circumference of the sub-drive gear to match the cable, and it is also installed on the sub-slave frame through a sub-slave shaft 22 The sub-driven gear 23 on the sub-driven gear is provided with a sub-slave semi-arc ring groove 24 that matches the cable and corresponds to the sub-master semi-arc ring groove on the outer circumference of the sub-driven gear. The auxiliary spring 28 that makes the auxiliary driven gear and the auxiliary driving gear elastically compress and mesh together, the auxiliary main half-arc ring groove and the auxiliary slave half-arc ring groove are evenly distributed with embossed lines 29 on the groove walls, and the auxiliary main frame is equipped with The auxiliary motor that drives the auxiliary driving gear to rotate, the linear speed of the auxiliary main half-arc ring groove to stir the cable is slightly faster than the linear speed of the rotating sleeve winding cable.

The sub-main frame is fixedly installed on the sub-frame, so the two are fixedly connected integral structures. The sub-slave frame is installed on the sub-frame through the slide rail, so the sub-slave frame can slide on the sub-frame along the slide rail, so the sub-slave frame and the sub-frame are in a relative sliding fit relationship. On the sub-frame, the slide rail is extended toward the sub-main frame, so when the sub-slave frame slides along the slide rail, the sub-slave frame also moves toward the sub-main frame or moves away from the sub-main frame. Sub-main frame is equipped with sub-main shaft, sub-drive gear is installed on sub-main shaft, so sub-drive gear can rotate around its axis line. The auxiliary motor that drives the auxiliary driving gear to rotate is also installed on the auxiliary main frame, so the auxiliary driving gear can be driven to rotate by connecting the auxiliary motor power supply. Second slave shaft is installed on the auxiliary slave frame, auxiliary driven gear is installed on the auxiliary slave shaft, auxiliary driven gear and auxiliary driving gear are meshed with each other, when auxiliary driving gear rotates like this, auxiliary driven gear also can rotate synchronously. A spring is installed between the sub-frame and the sub-slave frame, and the spring pushes the sub-slave frame to move toward the sub-main frame, even if the sub-driven gear and the sub-driving gear are elastically compressed and meshed together. An auxiliary main semi-arc ring groove is provided on the outer peripheral upper ring of the auxiliary driving gear, and the cross section of the auxiliary main semi-arc ring groove is a semicircle matching the outer circumference of the cable. The outer circumference of the auxiliary driven gear is also provided with an auxiliary slave half-arc ring groove. The cross section of the auxiliary slave half-arc ring groove is also a semicircle matching the outer circumference of the cable. set up. In this way, the connecting portion of the auxiliary main half-arc ring groove and the auxiliary slave half-arc ring groove is buckled into a circular cavity corresponding to the outer circumference of the cable, and this circular cavity is the passage that the cable must pass before winding. The groove walls of the auxiliary main half-arc ring groove and auxiliary slave half-arc ring groove are evenly distributed with embossed lines. Force or clamping force to prevent slipping, so that the sub-master semi-arc ring groove and the sub-slave half-arc ring groove can pull the distant cables smoothly and in time and send them to the cable end of the main frame. In this patent, the linear speed of the auxiliary main semi-arc ring groove toggling cable is slightly faster than the linear speed of the rotating sleeve winding cable. It is completed by moving the gear, so that the reverse pulling force of the cable when the swing arm ring is wound is very small and can be ignored, which greatly improves the accuracy of the patent for weighing the wound cable.

A buffer tube 30 is also installed on the base, and the buffer tube is arranged in a crescent shape in the axial direction, and the buffer tube is in the shape of a circular tube that is thicker in the middle and tapered at both ends in the radial direction, and the buffer tube inlet is set correspondingly to the subframe. The outlet of the outlet is correspondingly set with the swing arm of the main frame.

There are three main functions of the buffer tube. One function is that the two ends of the buffer tube are open and the middle is closed, so it can provide a transmission channel for the cables between the main frame and the sub-frame, and protect the cables from reliable and smooth transmission. The transmission will not be affected by the outside world. Because the line speed of the sub-main semi-arc ring slot to toggle the cable is faster than the line speed of the swing arm ring winding cable, there will be more and more redundancy between the main frame and the sub frame that cannot be wound by the swing arm ring in time. cable. The buffer tube is designed in a meniscus shape with thinner ends and a thicker middle. Its internal space is also wide in the middle and gradually narrows toward both ends. This space design can just provide outward expansion for gradually lengthening redundant cables. space. At the beginning of winding, the redundant cable between the main frame and the sub-frame is the shortest, and the honor cable is located at the shortest axial inner wall of the buffer tube, that is, the axial inner wall closest to the main frame and the sub-frame. In the middle stage of winding cables, there are more and more redundant cables, and the redundant cables will expand outward under their own bending elastic force, that is, move to the longest axial inner wall. In the later stage of winding the cable, the redundant cable will continue to expand outward under the action of its own axial elastic extension tension. At this time, the redundant cable will stick to the longest axial inner wall between the main frame and the sub-frame, that is, the and the axial inner wall farthest from the subframe. When the cable continues to be wound, since the buffer tube is in the shape of a circular tube in the radial direction, more and more redundant cables will be coiled in the inner cavity of the buffer tube under its own axial tension, so that the buffer tube can temporarily store more cable without significant pull on the swing arm ring. Therefore, the second function of the buffer tube is to provide storage space for these redundant cables. The third function of the buffer tube is to separate the cable from the human body, which fundamentally eliminates the accident of the cable winding around the human body, and the risk of the person's clothing and hair being rolled into the swing arm ring, which greatly improves the safety of the operator. safety.

In this embodiment, the lifting device includes an outer sleeve 34 fixed on the main frame, an inner sleeve 35 that can only slide axially along the inner wall of the outer sleeve is inserted in the outer sleeve, and the lower part of the inner cavity of the inner sleeve fits with the central shaft. And it can only be rotated and fitted. The inner wall of the upper part of the inner sleeve is provided with a main internal thread section 36, and also includes a transmission shaft 37 that is rotatably installed on the main frame. , transmission gear 39 is installed on the transmission shaft, also comprises the lifting motor 40 that is installed on the main frame, and the lifting gear 41 that meshes with transmission gear is installed on the output shaft of lifting motor.

The lifting device is an electrically driven lifting device, which is powered by a lifting motor. The output shaft of the lifting motor is equipped with a lifting gear, which meshes with the transmission gear, and the transmission gear is fixedly mounted on the transmission shaft that can only rotate axially but cannot move axially, so the transmission shaft will be driven to rotate synchronously when the lifting motor rotates. The lower part of the drive shaft is connected in transmission with the upper part of the inner sleeve, and the lower part of the inner sleeve is connected in transmission with the upper part of the central shaft. The inner sleeve is the core component of the lifting device, and the inner sleeve converts the rotational force of the transmission shaft into the lifting force of the central shaft. The inner sleeve is slidably inserted in the outer sleeve, and the outer sleeve is fixedly installed on the main frame, so the inner sleeve can only slide up and down axially relative to the outer sleeve and cannot rotate relative to the outer sleeve. The upper inner wall of the inner sleeve is provided with a main internal thread section, and the lower part of the transmission shaft is provided with a main external thread section, and the main external thread section and the main internal thread section are screwed together. Therefore, when the transmission shaft that can only rotate in the circumferential direction rotates, the transmission shaft will drive the inner sleeve that can only move axially to move up and down. Because the lower part of the inner cavity of the inner sleeve fits with the central shaft and the two cannot move axially relative to each other, when the inner sleeve moves up and down driven by the transmission shaft, the central shaft must also rise and fall thereupon. Therefore, as long as the positive and negative rotation of the lifting motor is controlled, the lifting of the central shaft can be controlled through the transmission shaft and the inner sleeve, which is very simple. The purpose of matching the lower part of the inner sleeve with the upper part of the central shaft can only rotate in the circumferential direction is to meet the requirement that the central shaft rotates synchronously with the swing arm ring when the cable is wound.

The inner sleeve includes an upper inner sleeve 42 and a lower inner sleeve 43. The lower inner sleeve includes a fixed lower half inner sleeve 44 and a movable lower half inner sleeve 45. The fixed lower half inner sleeve is coaxially fixed at the lower end of the upper inner sleeve. The half inner sleeve and the movable lower half inner sleeve are correspondingly provided with fixing holes 46, and fixing bolts 47 are inserted in the fixing holes, and a bearing groove 48 is arranged on the upper ring of the inner wall of the lower inner sleeve. The upper bearing 49.

The inner sleeve is mainly composed of three parts, namely the upper inner sleeve, the fixed lower half inner sleeve and the movable lower half inner sleeve. It is separated from the upper inner sleeve. In this inner sleeve, the fixed lower half inner sleeve and the movable lower half inner sleeve are two half sleeves arranged symmetrically along the plane where the axis line of the inner sleeve is located, and the fixed lower half inner sleeve and the movable lower half inner sleeve are correspondingly provided with fixed The fixed hole is inserted with a fixing bolt, and the fixed lower half inner sleeve and the movable lower half inner sleeve are buckled by the fixing bolt to form a lower inner sleeve coaxially arranged with the upper inner sleeve. The inner walls of the fixed lower inner sleeve and the movable lower inner sleeve are provided with bearing grooves corresponding to each other, and the bearing grooves are snap-fitted with the upper bearing outer ring fixedly installed on the upper part of the central shaft. After the fixed lower half inner sleeve and the movable lower half inner sleeve are fixed by fixing bolts, the upper part of the central shaft is fixedly installed to the lower part of the inner sleeve through the upper bearing, and the central shaft and the lower part of the inner sleeve can only be rotated and matched.

The main power device includes a main gear 31 installed on the rotary sleeve, and a main motor 32 installed on the main frame, and a power gear 33 meshing with the main gear is installed on the output shaft of the main motor. The active power device is an electric drive device, which mainly includes a main motor, a power gear and a main gear. Because the power gear and the main gear are meshed for transmission, when the main motor is powered on, the rotating sleeve will be driven to rotate through the transmission of the power gear and the main gear, and the swing arm ring can be driven to wind the cable.

Described cutting device comprises two cable anvils 50 that are fixed on the knife rest 16 at intervals, the cable anvil is provided with the cable groove 51 that horizontally slides with the lower half of the cable, and the knife rest is equipped with a lifting device driven by a cutting elevating device 54. Lifting frame 55, the lower part of the lifting frame is two supporting arms 56 extending downwards in parallel, the lower end of the supporting arm is fixedly equipped with a cutting saw blade 58 and a cutting motor 66 that drives the rotating supporting arm shaft through the rotating supporting arm shaft 57, the supporting arm Also fixedly be provided with vertically arranged pressing slide sleeve 67 on the top, slide and insert in the press slide sleeve and be equipped with press slide bar 68, press slide bar lower end is fixedly provided with the press block 69 that presses and cooperates with cable anvil up and down, press slide bar below. The pressing block is fixed with a downwardly extending pressing positioning rod 70, and the cable anvil is provided with a pressing positioning hole 71 that is plugged up and down with the pressing positioning rod. A pressing spring 73 is arranged on the pressing slide bar between the pressing block.

In this cutting device, the cable anvil, lifting frame and cutting lifting device are the core structures, and the cable anvil and cutting saw blade are the main parts for completing the cutting of cables. The cable anvil is fixedly installed at the bottom of the knife holder, so the two are fixed and integrated structures. The upper part of the cable anvil is provided with a cable groove that is slidingly matched with the cable. When the swing arm ring winds the cable, the cable slides through the cable groove first, and then is wound on the swing arm ring. The lifting frame is installed on the knife rest above the cable anvil, and the lifting frame is driven by the cutting lifting device to complete the lifting action. The lifting frame bottom is two support arms that are arranged up and down correspondingly with two cable anvils one by one. In this way, when the cutting motor is energized, the cutting saw blade is driven to rotate at a high speed through the support arm shaft. When the cutting lifting device drives the lifting frame down, the high-speed rotating cutting saw blade will cut the cables between the two cable grooves, thereby completing the work of cutting the cables. The rear sides of the two arms are respectively fixed with a vertically arranged pressing sliding sleeve, and a pressing sliding rod freely sliding up and down along the sliding sleeve is inserted in the pressing sliding sleeve. The upper end of the pressing slide bar is fixed with a pressing limit block to prevent the pressing slide bar from slipping downward from the pressing sliding sleeve. The lower end of the pressing slide bar is fixedly provided with a pressing block, which can also prevent the pressing slide bar from slipping upwards from the pressing sliding sleeve. Because the pressing block is set in one-to-one correspondence with the cable anvil, when the lifting frame moves downward, the pressing block also has the function of pressing the cable in the cable groove. A pressing spring is sleeved on the pressing slide bar between the pressing sliding sleeve and the pressing block, and the upper end of the pressing spring is elastically pressed against the lower end surface of the pressing sliding sleeve, and the lower end of the pressing spring is elastically pressed against the upper end surface of the pressing block. Therefore, under the action of its own gravity and the elastic force of the pressing spring, the pressing slide bar slides downwards to the maximum position relative to the pressing sliding sleeve when it is not subjected to other external forces. At this time, the length of the pressing slide bar sliding out of the pressing sliding sleeve is the longest, and the distance that the pressing block descends to the bottom of the cutting saw blade is also the farthest. For the convenience of description, this state is called the natural state or the superior state. When the cable needs to be cut, the lifting frame moves down driven by the cutting lifting device. Because the height of the pressing block is much lower than that of the cutting saw blade in the natural state, the pressing block will touch the cable in the cable groove before the cutting saw blade. Because the cable groove can only accommodate the lower part of the cable, the upper part of the cable is higher than the upper end face of the cable anvil, so when the lifting frame continues to descend, the lifting frame will continue to press the cable in the cable groove downwards by the pressing spring. At this time, the pressing spring is compressed and deformed, and the elastic force of the pressing spring to the pressing block is also increasing. After the cable is under pressure, it will gradually deform radially and fill the entire cable groove, which can play the role of pressing and fixing the cable to the cable anvil, and provides a guarantee for the smooth and reliable cutting of the cable by the cutting saw blade. It basically avoids the phenomenon that the cable rotates and rolls or even rolls out of the cable groove under the force of the cutting saw blade when the saw blade cuts the cable. After the cable is fixed, the cutting lifting device will continue to drive the lifting frame to descend, and the pressing spring will continue to compress and increase the pressing force on the cable. At this time, the cutting saw blade starts to touch the cable and starts to cut the cable. When the cutting and lifting device drives the lifting frame to reach the downstroke point, the pressing spring compresses the shortest, and the pressing and positioning force of the pressing block on the cable reaches the maximum. For convenience of description, this state is called cutting state or lower state. When the lower state is reset to the upper state, a cutting process is over. A pressing positioning rod extending downward is fixed on the pressing block below the pressing slide bar, and a pressing positioning hole is provided on the cable anvil to fit up and down with the pressing positioning rod. Before the pressing block presses the cable, the pressing positioning rod will be inserted into the pressing positioning hole first, which can provide a guiding effect for pressing the pressing block, ensure that the pressing block can be pressed down vertically, and ensure the smooth progress of the pressing positioning. The lower end of the pressing positioning rod is generally set thinner, so that even if there is an insertion error, the pressing positioning rod can be smoothly inserted into the pressing positioning hole.

The cutting and lifting device includes a large sleeve 59 fixed on the knife rest. The large sleeve is inserted with a small sleeve 60 that can only slide axially along the inner wall of the large sleeve. The upper inner wall is provided with a lifting internal thread section 61, which also includes a lifting transmission shaft 62 that is rotatably installed on the tool rest. Lifting transmission gear 64 is arranged, also comprises the cutting lifting motor 650 that is installed on the knife rest, and the cutting lifting gear that meshes with lifting transmission gear is installed on the output shaft of cutting lifting motor.

The cutting and lifting device is an electric-driven lifting device, which is powered by a cutting and lifting motor. The output shaft of the cutting and lifting motor is equipped with a cutting and lifting gear, which meshes with the lifting transmission gear. Drive the lifting drive shaft to rotate synchronously. The lower part of the lifting transmission shaft is connected with the upper part of the small sleeve, and the lower part of the small sleeve is fixedly connected with the upper end of the lifting frame. The small sleeve is the core component of the cutting and lifting device, and the small sleeve converts the rotational force of the lifting transmission shaft into the lifting force of the lifting frame. The small sleeve is slidably inserted in the large sleeve, and the large sleeve is fixedly installed on the tool rest, so the small sleeve can only slide up and down axially relative to the large sleeve and cannot rotate relative to the large sleeve. The upper inner wall of the small sleeve is provided with a lifting internal thread section, and the lower part of the lifting drive shaft is provided with a lifting external thread section, and the lifting external thread section and the lifting internal thread section are screwed together. Therefore, when the lifting transmission shaft that can only rotate in the circumferential direction rotates, the lifting transmission shaft will drive the small sleeve that can only move axially to move up and down, that is, the synchronous lifting of the drive lifting frame. Therefore, as long as the forward and reverse rotation of the cutting and lifting motor is controlled, the lifting of the lifting frame can be controlled through the lifting drive shaft and the small sleeve, which is very simple.

The start-stop device includes a main switch 52 installed on the power line of the main power unit and a lift switch 53 installed on the power line of the lifting device. The start and stop of the main power unit can be controlled by operating the main switch, that is, the swing arm ring is controlled to start and stop winding the cable, and the operation is very simple. It is very simple to control the rise and fall of the lifting device by operating the lift switch, that is, to control the rise and fall of the central axis, that is, to control the switching between the winding state and the throwing state.
