Description

Technical Field

[0001] This utility model relates to the field of hydraulic support maintenance technology, specifically a tail beam pin disassembly device. Background Technology

[0002] Because the hydraulic supports at the working face operate underground for extended periods, critical load-bearing components such as the top beam and shield beam experience excessive stress, frequently causing deformation of the tail beam hinge pins. These pins become difficult to remove during disassembly, hindering the disassembly process and reducing efficiency. Existing technologies use a cutting torch to melt the hinge pins or a pry bar to disassemble them, but this requires prolonged exposure to high temperatures, increasing the risk of burns to workers and resulting in high labor intensity. Therefore, a tail beam pin disassembly tool is proposed to facilitate the disassembly of tail beam pins. Utility Model Content

[0003] The purpose of this invention is to provide a tail beam pin disassembly tool to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The tail beam pin disassembly tool includes a support tube, one end of which is fixedly connected to a stop plate, and the other end of which is fixedly connected to a placement groove. A screw jack is placed in the placement groove. The telescopic head of the screw jack corresponds to and is adapted to the tail beam pin. The base of the screw jack is adapted to and inserted into the placement groove. The stop plate abuts against the inner side wall of the hydraulic support corresponding to the end face of the tail beam pin. A clamping mechanism is also provided on the outside of the support tube. The screw jack is equipped with a handle. The screw jack is a currently available product.

[0006] As a further embodiment of this utility model: the clamping mechanism includes a clamping ring, the inner diameter of which is adapted to the telescopic end of the screw jack, and an anti-slip pad is fixedly connected to the end face of the clamping ring. The anti-slip pad increases the friction of the end face of the clamping ring, which facilitates the clamping and fixing effect. Connecting arms are symmetrically fixedly connected to both sides of the clamping ring, and the ends of the connecting arms are bent inward.

[0007] As a further improvement of this utility model: the end of the connecting arm away from the clamping ring is fixedly connected to a movable ring, and the movable ring is sleeved on the support tube.

[0008] As a further embodiment of this utility model: three guide rods and one threaded rod are circumferentially connected to the moving ring. The guide rods slide through the moving ring, and the moving ring has a circular hole for the guide rods to pass through and slide. The threaded rod is threaded through the moving ring, and the moving ring has a threaded hole for the threaded rod to pass through.

[0009] As a further embodiment of this utility model: the two ends of the guide rod are fixedly connected to the corresponding side walls of the abutment and the placement groove, respectively, and the two ends of the threaded rod are rotatably installed to the corresponding side walls of the abutment and the placement groove.

[0010] As a further improvement of this utility model: a rotating head is fixedly connected to the threaded rod, and the threaded rod can be rotated by a tool through the rotating head.

[0011] As a further improvement of this utility model: the outer sliding buckle of the connecting arm is provided with a U-shaped guide buckle that is adapted to it. The U-shaped guide buckle is fixedly connected to the outer wall of the placement groove. The connecting arm is assisted in sliding and guided by the U-shaped guide buckle to improve stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention supports the screw jack by using a support tube in conjunction with a placement groove. The support tube abuts against the inner side wall of the hydraulic support through abutment plates. The telescopic end of the screw jack presses against the tail beam pin, thereby pushing the tail beam pin out of the other end of the mounting hole and completing the disassembly. Compared with using a cutting torch to melt the hinge pin or a pry bar to disassemble the pin, the operation is more convenient, labor-saving and safe.

[0014] The rotating threaded rod and the guiding rod drive the moving ring, which in turn drives the moving clamping ring through the connecting arm. The clamping ring and the clamping plate then press against the two end faces of the inner cavity of the disassembler's installation position, forming a clamping fixation. This limits the position of the support tube and keeps it vertical. As a result, only the screw jack needs to be operated during operation, without needing to hold the support tube by hand. Since both end faces of the support tube are pressed against the clamp, it can maintain linear alignment and prevent the support tube from tilting and failing to provide support when the screw jack applies force.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 In this embodiment of the utility model, the tail beam pin disassembly device includes a support tube 1, which is a steel pipe with a diameter of 24mm. One end of the support tube 1 is fixedly connected to a stop plate 2, and the other end of the support tube 1 is fixedly connected to a placement groove 3. The placement groove 3 is made by welding together a 15cm*15cm steel plate and four 14cm*3cm steel plates. A spiral jack 4 is placed in the placement groove 3. The telescopic head of the spiral jack 4 corresponds to and is adapted to the tail beam pin. The base of the spiral jack 4 is adapted to the placement groove 3 and inserted into the placement groove 3. The stop plate 2 abuts against the inner side wall corresponding to the end face of the hydraulic support and the tail beam pin. A clamping mechanism 5 is also provided on the outside of the support tube 1. The spiral jack 4 is provided with a handle 6. The spiral jack 4 is a product currently on the market.

[0021] By supporting the screw jack 4 with the support tube 1 and the placement groove 3, the support tube 1 is pressed against the inner side wall of the hydraulic support through the abutment plate 2. The telescopic end of the screw jack 4 presses against the tail beam pin, thereby pushing the tail beam pin out of the other end of the mounting hole and completing the disassembly. Compared with using a cutting torch to melt the hinge pin or a pry bar to disassemble the pin, the operation is more convenient, labor-saving and safe.

[0022] The clamping mechanism 5 includes a clamping ring 7. The inner diameter of the clamping ring 7 is adapted to the telescopic end of the screw jack 4. An anti-slip pad is fixedly connected to the end face of the clamping ring 7. The anti-slip pad increases the friction of the end face of the clamping ring 7, which facilitates the clamping and fixing effect. Connecting arms 8 are symmetrically fixedly connected to both sides of the clamping ring 7. The ends of the connecting arms 8 are bent inward.

[0023] The end of the connecting arm 8 away from the clamping ring 7 is fixedly connected to a movable ring 9, which is sleeved on the support tube 1.

[0024] The moving ring 9 is circumferentially connected with three guide rods 10 and one threaded rod 11. The guide rods 10 slide through the moving ring 9. The moving ring 9 has a circular hole for the guide rods 10 to pass through and slide. The threaded rod 11 is threaded through the moving ring 9. The moving ring 9 has a threaded hole for the threaded rod 11 to pass through.

[0025] The two ends of the guide rod 10 are fixedly connected to the corresponding side walls of the abutment 2 and the placement groove 3, respectively, and the two ends of the threaded rod 11 are rotatably installed to the corresponding side walls of the abutment 2 and the placement groove 3.

[0026] A rotating head 12 is fixedly connected to the threaded rod 11, and the threaded rod 11 can be rotated by a tool through the rotating head 12.

[0027] The outer side of the connecting arm 8 is provided with a U-shaped guide buckle 13 that is adapted to it. The U-shaped guide buckle 13 is fixedly connected to the outer side wall of the placement groove 3. The connecting arm 8 is assisted in sliding and guided by the U-shaped guide buckle 13 to improve stability.

[0028] The rotation of the threaded rod 11 and the guidance of the guide rod 10 drive the moving ring 9, which in turn drives the moving of the clamping ring 7 through the connecting arm 8. Thus, the clamping ring 7 and the clamping plate 2 abut against the two end faces of the inner cavity of the disassembler installation position, forming a clamping fixation. This limits the position of the support tube 1 and keeps it vertical. Therefore, during operation, only the screw jack 4 needs to be operated, without having to hold the support tube 1 by hand. Since both end faces of the support tube 1 are clamped, it can maintain linear alignment and prevent the support tube 1 from tilting and failing to support when the screw jack 4 applies force.

[0029] The working principle of this utility model is as follows:

[0030] In use, place the support tube 1 on the outside of the tail beam pin to be disassembled, and further align the abutment 2 with the inner wall of the hydraulic bracket corresponding to the end of the tail beam pin. At this time, rotate the threaded rod 11 by rotating the head 12. The rotation of the threaded rod 11 and the guidance of the guide rod 10 drive the moving ring 9, which in turn drives the abutment ring 7 to move through the connecting arm 8. Thus, the abutment ring 7 and the abutment 2 abut against the two end faces of the inner cavity of the disassembler installation position, forming a tight fixation, which limits the position of the support tube 1 and keeps it vertical. At this time, place the base of the screw jack 4 into the placement slot 3, and then support the screw jack 4 with the handle 6. Then, shake the operating rod of the screw jack to make the screw jack 4 work. The telescopic end of the screw jack 4 passes through the abutment ring 7 and abuts against the tail beam pin, pushing the tail beam pin out, completing the disassembly.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
