Description

Technical Field

[0001] This utility model relates to the field of mine cable relocation, specifically to an automatic mine cable relocation device. Background Technology

[0002] The tail cable of the working face conveyor is fixed on the monorail beam. Each time the coal mining machine returns to the tail of the working face, it is necessary to stop the coal mining machine and manually use a hand-operated hoist to lift the tail cable to prevent the coal mining machine drum from damaging the cable. After the coal mining machine finishes returning to the tail, after pushing the conveyor, it is necessary to manually use a hand-operated hoist to drag the tail cable forward. This is not only time-consuming and labor-intensive, but also requires stopping the operation of the coal mining machine, which affects the continuity of production at the working face. There is also the risk of damage to equipment, cables, and even personnel due to inadequate coordination of end-operators and inadequate cable protection. Utility Model Content

[0003] The purpose of this invention is to provide an automatic relocation device for mine cables, which solves the problem of time-consuming and labor-intensive cable relocation, thus affecting work efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic cable relocation device for mines includes a track laid in the mine, a moving component with a brake mounted on the track, a telescopic cylinder mounted above the moving component, a cylinder sleeve of the telescopic cylinder connected to the moving component via a moving platform, a piston rod connected to a fixed base, and a clamping element for clamping the cable mounted on the fixed base.

[0006] Furthermore, both the movable platform and the fixed base are provided with hinge seats. The cylinder sleeve of the telescopic cylinder is hinged to the movable platform through the hinge seats, and the piston rod of the telescopic cylinder is hinged to the fixed base through the hinge seats.

[0007] Furthermore, the clamping component is disposed at the bottom of the fixed base. The clamping component includes a primary sleeve, a secondary sleeve, and a threaded rod. The primary sleeve is sleeved on the outside of the secondary sleeve, and the threaded rod is disposed inside the secondary sleeve by means of a nut. The primary sleeve and the secondary sleeve are respectively provided with grippers for clamping the cable.

[0008] Furthermore, a bearing is provided in the inner cavity of the secondary sleeve, the bearing is located at the end away from the primary sleeve, and the nut is located at the end close to the primary sleeve; the outer ring of the bearing is fixedly connected to the inner wall of the secondary sleeve, and the inner ring is sleeved on the threaded rod; a wrench position is provided on the threaded rod, and the wrench position is located at the end away from the primary sleeve.

[0009] Furthermore, the gripper is arc-shaped.

[0010] Furthermore, the secondary sleeve is provided with a guide groove, and the inner wall of the primary sleeve is provided with a guide strip, which is adapted to the guide groove.

[0011] By adopting the above technical solution, the beneficial technical effects of this utility model are:

[0012] This invention first drives the threaded rod to rotate, causing the secondary sleeve to move towards the primary sleeve. This allows the clamps on both the primary and secondary sleeves to grip the cable. Then, the brake is engaged, and the telescopic cylinder extends, moving the cable forward. After the cable has moved, the brake is released, and the telescopic cylinder retracts. Under the cable's gravity, the telescopic cylinder moves forward again. This process is repeated to achieve automatic cable movement. This invention enables automatic cable movement, eliminating the need for manual cable movement using a chain hoist, thus improving work efficiency and reducing labor intensity.

[0014] Figure 2 This is a schematic diagram of the clamping component.

[0015] Figure 3 This is a cross-sectional view of the clamping component. Detailed Implementation

[0016] like Figure 1 As shown, an automatic cable relocation device for mines includes a track 1 laid in the mine. A moving component 2 equipped with a brake is mounted on the track 1, stopping the component 2. A telescopic cylinder 3 is positioned above the component 2. The cylinder sleeve of the telescopic cylinder 3 is connected to the component 2 via a moving platform 4. The piston rod of the cylinder 3 is connected to a fixed base 5, and a clamping element 6 for clamping the cable is mounted on the fixed base 5. The moving component 2 is installed on the track 1, and the cable is clamped using the clamping element 6. When the cable needs to move forward, the brake is applied to brake the component 2, and the telescopic cylinder 3 extends to move the cable forward. After reaching a specified length, the telescopic cylinder 3 stops extending, and the brake is released. The telescopic end of the cylinder 3 retracts, and under the weight of the cable, the telescopic cylinder 3 drives the moving component 2 forward along the track 1, completing a single automatic cable relocation. Repeating this process achieves automatic cable relocation, eliminating the need for manual operation of a hand-operated hoist, which is time-consuming, labor-intensive, and inefficient.

[0017] Both the movable platform 4 and the fixed base 5 are equipped with hinge seats 7. The cylinder sleeve of the telescopic cylinder 3 is hinged to the movable platform 4 via the hinge seats 7, allowing the telescopic cylinder 3 to rotate with the hinge seats 7 on the movable platform 4 as a reference. The piston rod of the telescopic cylinder 3 is hinged to the fixed base 5 via the hinge seats 7, allowing the telescopic cylinder 3 to rotate with the hinge seats 7 on the fixed base 5 as a reference. Due to the heavy weight of the cable, the two ends of the telescopic cylinder 3 are hinged to increase its degree of freedom and extend its service life.

[0018] like Figure 2 As shown, the clamping member 6 is disposed at the bottom of the fixed base 5. The clamping member 6 includes a primary sleeve 11, a secondary sleeve 12, and a threaded rod 13. The primary sleeve 11 is sleeved on the outside of the secondary sleeve 12. The threaded rod 13 is disposed inside the secondary sleeve 12 through a nut 14. The threaded rod 13 is threadedly connected to the nut 14. When the threaded rod 13 rotates clockwise, the threaded rod 13 will move relative to the nut 14, moving towards the primary sleeve 11. At the same time, the threaded rod 13 drives the secondary sleeve 12 to move towards the primary sleeve 11, causing the clamp 21 to move towards each other to clamp the cable. When the threaded rod 13 rotates counterclockwise, the threaded rod 13 moves away from the primary sleeve 11, and at the same time, the threaded rod 13 drives the secondary sleeve 12 to move away from the primary sleeve 11, causing the clamp 21 to move away from each other to release the cable.

[0019] like Figure 3 As shown, the primary sleeve 11 and the secondary sleeve 12 are respectively provided with clamps 21 for clamping the cable. When the threaded rod 13 moves towards the primary sleeve 11, the clamps 21 will clamp the cable. When the threaded rod 13 moves away from the primary sleeve 11, the clamps 21 will release the cable. The clamps 21 are arc-shaped and the radius of the clamps 21 is adapted to the cable to prevent the cable from loosening.

[0020] A bearing 22 is provided inside the secondary sleeve 12. The bearing 22 is located at the end away from the primary sleeve 11, and the nut 14 is located at the end closer to the primary sleeve 11. The outer ring of the bearing 22 is fixedly connected to the inner wall of the secondary sleeve 12, and the inner ring is fitted onto the threaded rod 13. A wrench position 23 is provided on the threaded rod 13, located at the end away from the primary sleeve 11. When the operator uses a tool to rotate the threaded rod 13 through the wrench position 23, the threaded rod 13 will rotate relative to the secondary sleeve 12. When the threaded rod 13 and the nut 14 move relative to each other, the bearing 22 will drive the secondary sleeve 12 to move closer to or away from the primary sleeve 11, shortening the distance between the two clamps 21 and achieving the purpose of clamping the cable.

[0021] The secondary sleeve 12 is provided with a guide groove 24, and the inner wall of the primary sleeve 11 is provided with a guide strip 25. The guide strip 25 is adapted to the guide groove 24. The secondary sleeve 12 slides in the primary sleeve 11. The guide groove 24 has a limiting effect on the secondary sleeve 12, which can effectively prevent the secondary sleeve 12 from rotating relative to the primary sleeve 11 and improve the smoothness of the movement of the secondary sleeve 12.

[0022] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
