Detailed Description

In order to make the technical problems, technical solutions and advantageous effects of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

The present invention will now be described in further detail with reference to specific examples, which are intended to be illustrative, but not limiting, of the invention.

Referring to fig. 1, a schematic perspective view of the offset adjusting device of the stepping self-moving tail of the present invention installed at the front end of the stepping self-moving tail is shown, wherein the offset adjusting device of the stepping self-moving tail and the stepping self-moving tail are fixedly connected together by bolts. Under the premise of avoiding the influence of the stepping self-moving tail deviation adjusting device on the normal passage of the passage in the mine, the stepping self-moving tail deviation adjusting device is installed between two head main guide rails 7 at the front end of the stepping self-moving tail, as shown in fig. 1 and 2.

As shown in fig. 3 and 4, the tail deviation adjusting device of the stepping self-moving machine of the present invention comprises a support rail 1, a lifting mechanism 2 and a driving mechanism 3.

The bottom of the support rail 1 is provided with a support surface 14 for generating static friction with the ground. The main function of the supporting surface 14 is that when the driving mechanism 3 drives one end of the stepping self-moving tail to move, the supporting rail 1 can stably catch the ground, and the supporting rail 1 provides a stable acting point to increase the stability of the stepping self-moving tail during adjustment. As shown in fig. 5, a plurality of trapezoidal groove structures and trapezoidal protrusion structures are distributed on the supporting surface 14 at the bottom of the supporting rail 1, the trapezoidal protrusion structures can go deep into the ground, and the trapezoidal groove structures can accommodate the upper soft soil layer, so that the supporting rail 1 can stably catch the ground when working on the soft ground.

The upper end of the support rail 1 is provided with a guide rail, as shown in fig. 1, the upper end of the support rail 1 is provided with a through groove, the through groove is a track 11 of the guide rail, the shape of a first slider 12 of the guide rail is matched with the through groove, the first slider 12 is slidably connected with the through groove, as shown in fig. 5, a first limiting part 13 is arranged above the through groove, the first limiting part 13 is connected with the support rail 1, the first slider 12 is limited between the first limiting part 13 and the through groove, one surface of the first slider 12 and the first limiting part 13 are in contact with each other, and the first slider 12 is slidably connected with the first limiting part 13.

In one example, as shown in fig. 5, the through slot on the support rail 1 has a rectangular cross section, the first slider 12 has a trapezoidal cross section, and the first stopper 13 has an L-shaped cross section. The first sliding block 12 is arranged in the through groove, and the first sliding block 12 is clamped in the through groove by the two L-shaped first limiting parts 13. And the two L-shaped first limit parts 13 are fixedly connected with the support rail 1. The effect obtained is that the first slider 12 can slide on the support rail 1. At the same time, after lifting the first slider 12, the support rail 1 can also be lifted together with the first slider 12. The design of this department makes the tail of taking a step from the in-process that moves forward constantly, and whole tail deviation adjusting device of taking a step from moving need not artificial constantly to carry and supports rail 1 along with the change of position, has saved manpower resources, has reduced operating personnel injured's possibility.

In another example, as shown in fig. 6, the cross section of the first slider 12 is trapezoidal, the cross section of the first limiting member 13 is triangular, and the two triangular first limiting members 13 clamp the first slider 12 in the through groove. Two triangular first limiting parts 13 are fixedly connected with the support rail 1. The effect obtained is that the first slider 12 can slide on the support rail 1. At the same time, after lifting the first slider 12, the support rail 1 can also be lifted together with the first slider 12. The design of this department makes the tail of taking a step from the in-process that moves forward constantly, and whole tail deviation adjusting device of taking a step from moving need not artificial constantly to carry and supports rail 1 along with the change of position, has saved manpower resources, has reduced operating personnel injured's possibility.

The support rail 1 thus provides a stable supporting action as well as a stable guiding action. Provides a stable pivot for the self-advancing tail which needs to be lifted. And when the driving mechanism 3 moves the deviation adjusting direction of the stepping self-moving tail, a force application point is provided for the driving mechanism 3, and when the stepping self-moving tail stops, the inertia force of the stepping self-moving tail is transmitted to the ground. Finally, the stable deviation adjustment of the stepping self-moving tail in a specific direction is realized, and the vibration during the deviation adjustment of the stepping self-moving tail is reduced.

The lifting mechanism 2 is used for lifting the end part of the stepping self-moving tail, the lifting mechanism 2 is positioned above the supporting rail 1, the telescopic end of the lifting mechanism 2 is connected with the first sliding block 12 of the guide rail, and the body of the lifting mechanism 2 is connected with the stepping self-moving tail. When the end part of the stepping self-moving tail is lifted, the telescopic end of the lifting mechanism 2 extends out, and along with the extension of the telescopic end, the lifting mechanism 2 expands the relative distance between the first sliding block 12 on the guide rail and the stepping self-moving tail. After the supporting surface 14 at the bottom of the supporting rail 1 is grounded, the supporting rail 1 is static under the supporting action of the ground. Then, with the extension of the telescopic end, one end of the stepping self-moving tail is slowly lifted. Because the lifting mechanism 2 is connected with the first slide block 12, and the first slide block 12 can slide in the guiding direction of the guide rail, when the self-moving tail is moved next, only the friction force between the first slide block 12 and the rail 11 on the guide rail needs to be overcome, and the moving power required by moving the self-moving tail is greatly reduced. The lifting mechanism 2 may be implemented in various embodiments, for example, by using a combination of a telescopic cylinder, a ball screw nut pair and a motor, or a jack.

In specific use, a first fixed connecting part 21 for fixedly connecting with the body of the stepping self-moving tail is arranged on the body of the lifting mechanism 2, and a second fixed connecting part 22 for fixedly connecting with the first sliding block 12 is arranged at the driving end of the lifting mechanism 2. When the driving mechanism 3 drives the first slider 12 to move along the guiding direction of the track 11 of the guide rail, the first fixed connecting portion 21 and the second fixed connecting portion 22 drive the body of the lifting mechanism 2, the first slider 12 and the stepping self-moving tail to synchronously move.

As shown in fig. 2, the first fixed connection portion 21 is used to fixedly connect the main body of the lifting mechanism 2 and the main body of the stepping self-advancing tail. As shown in fig. 1, the second fixing connection portion 22 is used to fixedly connect the driving end of the lifting mechanism 2 with the first slider 12, so that the body of the lifting mechanism 2, the first slider 12 and the stepping self-moving tail are integrated. Finally, when the driving mechanism 3 drives the first slider 12 to move under the connection of the first fixed connecting portion 21 and the second fixed connecting portion 22, the first slider 12 can drive the lifting mechanism 2 and the lifting end of the stepping self-moving tail to move together. The first fixing connection part 21 may adopt various embodiments, for example, the first fixing connection part 21 is a bolt or a welded portion formed by a welding method. The second fixing connection portion 22 may adopt various embodiments, for example, the first fixing connection portion 21 is a bolt or a welded portion formed by a welding method.

The body of the driving mechanism 3 is relatively fixedly connected with the body of the support rail 1, the driving end of the driving mechanism 3 is in transmission connection with the first sliding block 12, and the driving direction of the driving mechanism 3 is parallel to the guiding direction of the guide rail. The driving mechanism 3 is used for driving the first sliding block 12 to slide back and forth along the guide rail on the supporting rail 1 and driving the stepping self-moving tail to move so as to carry out deviation adjustment work. The driving mechanism 3 may employ various embodiments, for example, a cylinder drive, a linear driving mechanism using a combination of a ball screw nut pair and a servo motor, or a pneumatic cylinder.

Referring to fig. 1, in order to lift the tail of the stepping self-propelled machine more stably and increase the overall lifting force, a plurality of lifting mechanisms 2 may be used simultaneously, a connecting frame 23 for fixing on the tail of the stepping self-propelled machine is provided outside the plurality of lifting mechanisms 2, and the bodies of the plurality of lifting mechanisms 2 are fixed in the connecting frame 23. The use of the connecting frame 23 can expand the number of the lifting mechanisms 2 and facilitate the interconnection of a plurality of lifting mechanisms 2 and the tail of the stepping self-moving machine.

When the device works, the main guide rail 7 of the machine head of the stepping self-moving machine tail is adjusted to be in a suspended state when the stepping self-moving machine tail needing to be adjusted is adjusted to be offset. Referring to fig. 1, the lifting mechanism 2 extends out, the supporting rail 1 is lowered until contacting with the ground, and then the lifting mechanism 2 continues to extend out, and the lifting mechanism 2 lifts up the tail end of the walking machine due to the support of the supporting rail 1. After the stepping self-moving tail is lifted, the telescopic end of the lifting mechanism 2 is locked, and the lifting state of the stepping self-moving tail is kept.

Then, the driving mechanism 3 drives the first sliding block 12 to move left or right, and the first sliding block 12 drives one end of the whole stepping self-moving tail to synchronously move left or right. After the first sliding block 12 adjusts the stepping self-moving tail to a required position, the driving end of the driving mechanism 3 is locked. The lifting mechanism 2 retracts, and the lifted end of the whole stepping self-moving tail descends until the lifted end of the stepping self-moving tail is contacted with the ground. Reference is made to fig. 9, which illustrates the range within which the head main guide 7 can be offset. When the main guide rail 7 of the machine head deflects, the advancing direction of the moving tail of the stepping self-moving machine changes along with the deflecting direction of the main guide rail 7 of the machine head.

In summary, in the offset adjusting device for the tail of the stepping self-moving machine provided by the invention, during offset adjustment, the lifting mechanism and the supporting rail which are matched with each other are used, the lifting mechanism lifts the end part of the tail of the stepping self-moving machine, and the supporting rail enables the end part of one end of the lifted tail of the stepping self-moving machine to slide relative to the ground through the guide rail at the upper end of the supporting rail. During deviation adjustment, the driving mechanism drives the first sliding block of the guide rail to move, the first sliding block drives the whole lifting mechanism to move, the lifting mechanism drives one end of the lifted stepping self-moving tail to slide simultaneously, the end direction of the stepping self-moving tail is adjusted, and finally deviation adjustment work of the stepping self-moving tail is completed. The invention can quickly adjust the offset direction of the tail adjustment of the stepping self-moving machine, reduce the personnel investment, save the construction cost and ensure the personnel safety.

Referring to fig. 1, fig. 2, fig. 7 and fig. 8, the invention further discloses a self-advancing tail, wherein the end of the self-advancing tail is connected with the self-advancing tail deviation adjusting device, and the deviation adjusting direction of the self-advancing tail deviation adjusting device intersects with the moving direction of the self-advancing tail. The beneficial effects of the stepping self-moving tail disclosed by the invention are the same as the beneficial effects of the stepping self-moving tail deviation adjusting device in the technical scheme, and the details are not repeated herein.

Further, referring to fig. 1, fig. 2 and fig. 7, another embodiment of the present invention relates to a stepping self-moving tail, wherein the stepping self-moving tail includes a traction portion 4, and the traction portion 4 is a walking head of the whole stepping self-moving tail, and drives the whole stepping self-moving tail to step forward. The traction part 4 comprises a traction part frame body 41, a first walking lifting device 5, a telescopic pushing device 6 and a machine head main guide rail 7. The towing portion frame body 41 is a support member, and the first traveling lifting device 5 lifts one end of the towing portion 4 by lifting the towing portion frame body 41. Typically there are two first travelling lifting devices 5, which are distributed on both sides of the towing part 4.

Two main head guide rails 7 are respectively arranged on two sides of the traction part frame body 41, a first walking lifting device 5 is arranged between the traction part frame body 41 and each main head guide rail 7, the body of the first walking lifting device 5 is connected with the traction part frame body 41, and the lifting end of the first walking lifting device 5 is fixedly connected with the second sliding block 71 of the main head guide rail. The telescopic pushing device 6 is arranged between the traction part frame body 41 and the main head guide rail 7, the telescopic direction of the telescopic pushing device 6 is the same as the guide direction of the main head guide rail 7, one end of the telescopic pushing device 6 is connected with the traction part frame body 41, and the other end of the telescopic pushing device 6 is connected with the main head guide rail 7. Wherein, the connection mode of the telescopic pushing device 6 and the traction part frame body 41 is hinged, and the connection mode of the telescopic pushing device 6 and the main guide rail 7 of the machine head is hinged. In practical use, the second sliding block 71 is usually a pulley block, and the bottom of the pulley block is provided with a hook. The bottom of the towing part frame body 41 is provided with a grounding support pillow 411, and the towing part frame body 41 is stably connected to the ground through the grounding support pillow 411.

In order to facilitate understanding of the working process, the drawing unit frame body 41 is in a suspended state, and the time when the head main guide rail 7 supports the gravity of the entire drawing unit frame body 41 is used as an initial state. The first traveling lift device 5 is retracted, the grounding support pillow 411 is grounded, and the towing part frame body 41 is supported above the ground by the grounding support pillow 411. Then, the first walking and lifting device 5 drives the main head rail 7 to lift, the main head rail 7 is far away from the ground, and the traction part frame body 41 supports the weight of the whole traction part 4. Then the telescopic pushing device 6 retracts to drive the main guide rail 7 of the machine head to move forwards. After the head main guide rail 7 moves forward and finishes, the first walking lifting device 5 extends out to drive the head main guide rail 7 to be close to the ground, after the head main guide rail 7 is contacted with the ground, the first walking lifting device 5 continues to extend out, the first walking lifting device 5 drives the whole traction part frame body 41 to lift, the traction part frame body 41 is suspended above the ground, and the traction part 4 finishes a walking cycle of marking time in the working process.

Further, as shown in fig. 1, in another embodiment of the stepping self-moving tail of the present invention, the first walking lifting devices 5 located at one end of the stepping self-moving tail deviation adjusting device are fixedly disposed at both sides of the stepping self-moving tail deviation adjusting device, and the first walking lifting devices 5 located at one end of the stepping self-moving tail deviation adjusting device are connected to the towing part frame body 41 through the connecting frame 23 of the stepping self-moving tail deviation adjusting device. In the above embodiment, after the first walking and lifting device 5 is fixed on both sides of the connecting frame 23, the connecting position of the first walking and lifting device 5 to be connected is released on the towing part frame body 41, and the mounting position of the telescopic pushing and moving device 6 can be closer to the end of the towing part frame body 41. In the case where the length of the head main guide 7 is constant, the maximum extension distance of the telescopic pusher jack 6 becomes longer as the mounting position of the telescopic pusher jack 6 becomes closer to the end of the traction part frame 41. This is because, as shown in fig. 2, since the elevating mechanisms 2 are provided on both the front and rear sides of the traction portion 4, there is a possibility that the joint end of the telescopic thrust moving device 6 and the head main guide 7 may collide with the elevating mechanism 2 on the rear side of the traction portion 4 in the process of extending the telescopic thrust moving device 6, and therefore the maximum extending distance of the telescopic thrust moving device 6 is limited to between the elevating mechanisms 2 on both the front and rear sides of the traction portion 4. The coupling point on the towing part carrier 41, to which the first lifting means 5 is attached, is thus freed, so that the telescopic sliding device 6 is mounted further forward on the towing part carrier 41 and the maximum extension of the telescopic sliding device 6 is increased.

Further, referring to fig. 2 and 7, in another embodiment of the stepping self-moving tail of the present invention, the traction portion 4 further includes a motor oil pump unit 8, the motor oil pump unit 8 is disposed on the traction portion frame 41, the first walking lifting device 5 and the telescopic pushing device 6 are both driven by a hydraulic oil pump, and a power output end of the motor oil pump unit 8 is connected to a power input end of the first walking lifting device 5 and a power input end of the telescopic pushing device 6, respectively.

In the prior art, the motor oil pump unit 8 is generally arranged at the position of the material storage part in fig. 7, so that a connecting pipeline is very long, wiring is troublesome, and the power output of the motor oil pump unit 8 is influenced.

Further, referring to fig. 7 and 10, another embodiment of the stepping self-moving tail of the present invention further includes a rigid transportation portion connected to the rear end of the traction portion 4, the rigid transportation portion includes a first transportation frame body 91, a second walking lifting device 92 and a first support rail 93, the first transportation frame body 91 is hinged to the traction portion frame body 41, the main head rail 7 is hinged to the first support rail 93 along the horizontal direction, two sides of the first transportation frame body 91 are respectively provided with at least one second walking lifting device 92, a body of the second walking lifting device 92 is fixedly connected to the first transportation frame body 91, and a lifting end of the second walking lifting device 92 is connected to a third slider of the first support rail 93.

In the above embodiment, the rigid transportation part is connected to the rear end of the traction part 4, the rigid transportation part is provided with the sliding type belt machine turnabout drum tensioning device 9 and a device for slowly changing the angle of the belt, the inclination angle of the belt is changed from 30 degrees to 20 degrees, then is changed to 15 degrees, and then is wound on the turnabout drum, and the belt is changed.

Referring to fig. 10 to 13, an overall structure of a belt machine direction-changing drum tensioning device 9 in a sliding mode is illustrated, and the belt machine direction-changing drum tensioning device 9 in the sliding mode comprises a direction-changing drum 911, a first guide slide rail 912 and a second guide slide rail 914 which are symmetrically distributed on two sides of the direction-changing drum 911, and a moving device.

The direction-changing drum 911 is a driven drum, that is, the direction-changing drum 911 is rotated by the belt 9111 when the belt 9111 runs. The direction-changing drum 911 is located at the tail end.

The first guide rail 912 and the second guide rail 914 are symmetrically distributed on two sides of the direction-changing drum 911. One end of the direction-changing drum 911 is connected to the first slider 9121 of the first guide slide rail 912, and the other end of the direction-changing drum 911 is connected to the second slider 9141 of the second guide slide rail 914. And the guiding directions of the first guide rail 912 and the second guide rail 914 are the same. The direction-changing drum 911 can be stably moved back and forth under the common guide of the first guide rail 912 and the second guide rail 914. It is ensured that the tension of the belt 9111 can be stably adjusted by adjusting the forward and backward movement of the direction-changing drum 91 during the operation of the belt 9111. The problem of deviation of the belt 9111 is reduced due to the improvement of the stability of the position adjustment of the direction-changing drum 911.

In one example, the first guiding slide rail 912 is a first plate-shaped body having a first guiding through groove in the middle, the first rail 9122 of the first guiding slide rail 912 is the first guiding through groove, the first sliding block 9121 is a first square sliding block matched with the first guiding through groove in shape, the first square sliding block is located in the first guiding through groove, and the first square sliding block is slidably connected with the first guiding through groove. When the tightness of the belt 9111 is adjusted, the requirements on the precision of the guide device and the friction force between the slide block and the slide rail are low. And the requirement on the bearing capacity of the sliding rail and the sliding block of the guide device is high. Therefore, the first guiding sliding rail 912 adopts the combination of the first plate-shaped body and the first square sliding block, so as to simplify the structure, and abandon the use of the roller, so that the roller is firm and durable. And certain friction force is arranged between the first rail 9122 in the first guide through groove and the first sliding block 9121, and the friction force can play a role in reducing the vibration of the direction-changing drum 911 to a certain extent, so that the belt 9111 runs more stably.

First stopper is connected with respectively in first square sliding block both sides, and the diameter of first stopper is greater than the width that first direction led to the groove, first stopper and the surperficial sliding connection of first platelike body. The first stopper is used for preventing the first slider 9121 from deviating from the first rail 9122, and ensuring smooth forward and backward movement of the direction-changing drum 911. In an implementable scheme, the first limiting block is detachably connected with the first square sliding block. The detachable connection has the advantage that when the first limiting block or the first square sliding block is abraded greatly, the first limiting block or the first square sliding block can be conveniently and independently replaced.

The second guide slide rail 914 is a second plate-shaped body with a second guide through groove in the middle, the second track 9142 of the second guide slide rail 914 is a second guide through groove, the second slider 9141 is a second square sliding block matched with the second guide through groove in shape, the second square sliding block is located in the second guide through groove, and the second square sliding block is connected with the second guide through groove in a sliding manner. When the tightness of the belt 9111 is adjusted, the requirements on the precision of the guide device and the friction force between the slide block and the slide rail are low. And the requirement on the bearing capacity of the sliding rail and the sliding block of the guide device is higher. Therefore, the second guide rail 914 is a combination of the second plate-like body and the second square slide block, so as to simplify the structure thereof, and the use of the roller is abandoned, so that the roller is strong and durable. In addition, a certain friction force is arranged between the second rail 9142 and the second sliding block 9141 in the second guiding through groove, and the friction force can play a role in reducing the vibration of the direction-changing drum 911 to a certain extent, so that the belt 9111 runs more stably.

The two sides of the second square sliding block are respectively connected with a second limiting block, the diameter of the second limiting block is larger than the width of the second guide through groove, and the second limiting block is connected with the surface of the second plate-shaped body in a sliding mode. The second stopper is used for preventing the second slider 9141 from deviating from the second rail 9142, and ensuring smooth forward and backward movement of the direction-changing drum 911. In an implementable scheme, the second limiting block is detachably connected with the second square sliding block. The above-mentioned benefit of dismantling the connection is, when second stopper or the square sliding block wearing and tearing of second are great, can conveniently change second stopper or the square sliding block of second alone.

The driving end of the driving means is connected to the first slider 9121 and/or the second slider 9141. The driving device functions to drive the direction-changing drum 911 to move forward and backward and to increase the interaction force between the direction-changing drum 911 and the belt 9111, so that the direction-changing drum 911 can open the belt 9111 to give a tension to the belt 9111.

In one example, the driving device includes a first driving portion 913 and a second driving portion 915 distributed on both sides of the direction-changing drum 911, the first driving portion 913 is in transmission connection with the first slider 9121, and the second driving portion 915 is in transmission connection with the second slider 9141. The first driving part 913 or the second driving part 915 has various options in selection, for example, a combination of an air cylinder, a driving oil cylinder, a ball screw pair and a servo motor or a combination of a link device and a servo motor capable of outputting linear power is used. By adopting the first driving portion 913 and the second driving portion 915 which are positioned on both sides of the direction-changing drum 911, the forward and backward movement of the direction-changing drum 911 is adjusted by a dual-drive manner, so that the first driving portion 913 or the second driving portion 915 can be effectively prevented from being in direct contact with the direction-changing drum 911, and the mounting manner of the first driving portion 913 and the second driving portion 915 is also simplified, that is, the first driving portion 913 and the second driving portion 915 are directly in transmission connection with the first slider 9121 and the second slider 9141 which are positioned on the outermost sides.

Referring to fig. 10-13, in operation, the direction-changing drum 911 is operated in conjunction with a belt 9111. When the belt 9111 is in a slack condition, the working end of the first driving portion 913 and the working end of the second driving portion 915 simultaneously extend leftward, the first slider 9121 is driven by the first driving portion 913 to move leftward, and the second slider 9141 is driven by the second driving portion 915 to move leftward. The direction-changing drums 911 disposed between the first and

second sliders

9121 and 9141 are moved leftward by the first and

second sliders

9121 and 9141. The bend drum 911 stretches the belt 9111, and the tensioning of the belt 9111 is realized.

In summary, in the sliding belt conveyor direction-changing drum tensioning device 9, the direction-changing drum can stably move forward and backward through the first guide slide rail and the second guide slide rail, so that the belt tension can be stably adjusted without stopping the belt.
