Description

Cable bender

technical field

The invention relates to the field of electric wiring construction, in particular to a cable bender.

Background technique

In the process of releasing cables such as high and low voltage cables and optical cables, the cable turns 90 degrees in the working well for a long time. Generally, it is released by hanging the pulley with the tension ring in the well. The cable is unstable during the process of releasing the cable, which is easy to cause the release process. Appearance from the pulley. Moreover, the pulley has its own weight, and it will still sag naturally after being connected with the tension ring with a rope, causing it to be out of line with the cable release. Due to the tension, once the pull ring falls off, the pulley will also fall, which will cause damage to the cable; and once the pull ring falls, the wiring construction must be stopped, and the cable cannot continue to be deployed, and can only be reinstalled on the pull ring. The construction can only be continued after it is fixed, which increases the time of abnormal work; or the cables are deployed one by one, but it is easy to cause the cables to be strained and twisted. That is, in the existing cable release process, there are the following defects: the height of the pulley cannot be fixed at the same height as the cable release channel, resulting in torque changes, which consumes the efficiency of pulling manpower or equipment; because the pulley fixed on the tension ring is affected The pulling force of the cable makes it easy to cause the pull ring to fall off, causing accidents; the pull ring falls off and the work cannot continue; the cable sheath is easy to pull the cable sheath when it is cast; the cable is prone to twisting and damage.

Contents of the invention

The object of the present invention is to provide a cable bender, which can ensure the fast passage of the cable when turning at 90 degrees, and avoid damage caused by uneven force on the cable due to unstable fixing of the pulley.

The object of the present invention is achieved through the following technical solutions:

The cable bender includes the quadrilateral A-pillar, B-pillar, C-pillar and D-pillar formed by hinged joints at the first and last ends. The C-pillar is composed of the lower section of the C-pillar and the upper section of the C-pillar, and rotates on the upper section of the C-pillar. The main runner is provided, and a strip-shaped hole is opened at the lower end of the upper section of the C-pillar, and a through hole corresponding to the strip-shaped hole is provided at the lower section of the C-pillar. Next link. In the corner cable shaft, the corner corner of the cable is often realized by the fixed pulley on the tension ring as a support point, but in the actual use process, the height of the pulley cannot be fixed to be equal to the cable release channel, which will cause the cable The change of the torque of the cable on the pulley makes the manual traction of the cable more laborious when it is deployed, and consumes more efficiency in manpower or equipment. Moreover, due to the multi-layer arrangement of the cable tube on the side wall of the corner well, the fixing of the roller It needs to spend more steel cables on the tension ring to realize it, and the operation is cumbersome, which increases the abnormal working time and greatly reduces the work efficiency. Once the pulley is not evenly stressed on the tension ring, the pulley will have displacement deviation, and then Cause cable damage, resulting in significant economic losses;

The main runner on the column allows the cable to pass through the main runner at an angle of 90 degrees and pass through another wire tube. At this time, when the cable is in contact with the outer wall of the main runner, it will produce a vibration perpendicular to the outer wall of the main runner and The inward pressure, rather than the pull or traction in other directions, makes the cable and the main runner move or rotate stably, preventing the multi-directional stress between the cable and the main runner from causing damage to it. The direction of the cable is changed through the wheel of the device, and the cable is guided to pass through. If there are many corners along the way, the cable can be installed with more than one device as required, which is convenient for one-time release of the cable and avoids the damage to the cable caused by single-stage release.

Equal, in order to reduce the distortion of the cable on the main runner, the vertical distance between the B-pillar and the D-pillar can be slightly adjusted manually or through the driving device. When the bolt is stuck, it can also be realized. After the cable laying process is completed, the device is dismantled to facilitate the next use; and after the wiring construction is completed, the entire device can be disassembled only by removing the bolts.

Further, two opposite brackets are fixed on the upper end of the upper section of the C-pillar, and auxiliary wheels are rotatably arranged on the brackets. The cable will inevitably run out in the radial direction during the threading process, and the cable is also easy to slip out of the main runner, which will affect the progress of the cable release; the present invention is fixedly arranged at the end of the C-pillar with two The bracket is equipped with an auxiliary runner rotating on the bracket. When the cable is passed through the wire tube, the outer wall of the auxiliary runner contacts the outer wall of the cable. The wheel can move relative to the cable without hindering the movement of the cable, so as to ensure that the cable will not come out of the main runner in the main runner when the cable is loose during release.

Further, it also includes a driving regulator fixed on the D-pillar, the driving regulator is a jack or a screw jack, and the output end of the jack or the screw jack is connected to the top of the B-pillar. In each corner well, the horizontal height of the line pipe from the bottom of the well is different, the A column is parallel to the side wall of the corner well, and the fixed length of the A column cannot be used for many line pipe heights, and the C column in the present invention consists of two parts Composition, the upper section of the C-pillar and the lower section of the C-pillar are connected by bolts, and the strip hole at the end of the upper section of the C-pillar can ensure that the distance between the upper section of the C-pillar and the lower section of the C-pillar can be adjusted. Realize the rotation movement of B-pillar around the hinge point of B-pillar and A-pillar, and then realize the forward or backward of the upper part of C-pillar, the main runner and the auxiliary runner, so as to adapt to various types of corner wells and greatly improve the cost. Applicability of the invention.

Further, the main runner is a V-groove guide roller. Preferably, a V-groove guide roller is used, so that the outer wall of the cable is closely attached to the V-shaped groove of the guide roller, so as to prevent the cable from accidentally slipping out on the runner and causing damage.

Further, the auxiliary wheels are rubber rollers. Preferably, the rubber roller realizes a flexible connection when in contact with the cable, so as to avoid hard damage to the outer wall of the cable by the auxiliary runner, thereby achieving the purpose of protecting the cable.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

1. The cable of the present invention changes direction through the rotating wheel of the device, and guides the cable to pass. If there are multiple corners along the cable, multiple devices can be installed according to requirements, so as to facilitate one-time release of the cable and avoid single-stage release. Damage to the cables; among them, the C-pillar is composed of the upper section of the C-pillar and the lower section of the C-pillar connected by bolts, and a strip hole is opened at the end of the upper section of the C-pillar, and the vertical height of the A-pillar is the same as the movement level of the cables in the wire tube The heights are not necessarily exactly equal. In order to reduce the distortion of the cables on the main runner, the vertical distance between the B-pillar and the D-pillar can be slightly adjusted manually or through a driving device;
