Description

Technical Field

[0001] This utility model relates to the field of belt conveyor anti-deviation technology, and in particular to an adjustable support device for anti-deviation of belt conveyors used in coal mines. Background Technology

[0002] Belt conveyors are used in coal mines to transport raw coal, gangue, and other materials over long distances. Due to uneven material distribution, variations in belt tension, and roller wear, lateral deviation is prone to occur. Traditional fixed support anti-deviation devices are not adjustable and tend to generate rigid friction with the belt edge, leading to accelerated belt wear. Therefore, an adjustable anti-deviation support device for coal mine belt conveyors is needed.

[0003] Coal mines present diverse working conditions. An adjustable anti-deviation support device for coal mine belt conveyors can flexibly adapt to different belt specifications for adjustment, dynamically correcting belt misalignment, adapting to complex working conditions, and ensuring continuous transportation. However, in previous technologies, due to variations in belt width and thickness in coal mine conveyors, and different belt height requirements in different roadways or transportation stages, the lack of adjustable support height and the inability to adjust the support position according to belt specifications could lead to poor contact between the belt and the support components, resulting in a loss of the corrective effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable anti-deviation support device for belt conveyors in coal mines, which aims to improve the problems in the prior art that lack lifting function, have a fixed support height, cannot adjust the support position according to the belt specifications, and may lead to poor contact between the belt and the support components, resulting in loss of the correction effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable anti-deviation support device for a coal mine belt conveyor, comprising a base plate, a limit plate fixedly connected to the upper surface of the base plate, a movable plate slidably connected to the outer wall of the limit plate, a support plate fixedly connected to the outer wall of the limit plate, a motor fixedly connected to the upper surface of the support plate, a bidirectional threaded rod fixedly provided at the output end of the motor, a manual component provided at the other end of the bidirectional threaded rod, a rotatably connected inner wall of the bidirectional threaded rod to the limit plate, a threaded block threadedly connected to the outer wall of the bidirectional threaded rod, a connecting shaft fixedly connected to the outer wall of the threaded block, a rotating rod rotatably connected to the outer wall of the connecting shaft, a second connecting shaft rotatably connected to the inner wall of the rotating rod, a connecting block fixedly connected to the outer wall of the second connecting shaft, an anti-deviation component provided on the upper surface of the movable plate.

[0006] The above technical solution allows for the following: when the belt deviates from its designated path, starting motor one or a manual component can drive the bidirectional threaded rod to rotate. The threaded connection drives the threaded block to move, and the linkage between the rotating rod and connecting shaft one and connecting shaft two can push the moving plate to move horizontally up and down under the limit of the limiting plate. By adjusting the height of the bracket in the anti-deviation component, the force distribution on the belt can be changed, thus achieving belt deviation correction.

[0007] Preferably, the manual component includes a locking block, the outer wall of which is fixedly connected to the other end of the bidirectional threaded rod, and a handle is engaged with the outer wall of the locking block, the handle being disposed on the outer wall of the bidirectional threaded rod.

[0008] Preferably, the anti-deviation component includes a support block one and a support block two, the lower surfaces of the support block one and the support block two are fixedly connected to the lower surface of the moving plate, and the outer walls of the support block one and the support block two are fixedly connected to a fixing block.

[0009] Preferably, a second motor is fixedly connected inside the fixed block, and a threaded shaft is fixedly provided at the output end of the second motor. The outer wall of the threaded shaft is rotatably connected to the outer wall of the fixed block.

[0010] Preferably, the outer wall of the threaded shaft is threadedly connected to a sliding block, the inside of the fixed block is provided with a sliding groove, the outer wall of the sliding block is slidably connected to the inner wall of the sliding groove, the inside of the sliding block is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is rotatably connected to a roller, the outer wall of the fixed block is fixedly connected to a fixed plate, and the outer wall of the rotating shaft is fixedly connected to the inside of the fixed plate.

[0011] Preferably, a first rotating shaft is fixedly connected to the lower surface of the sliding block, a first rotating plate is rotatably connected to the outer wall of the first rotating shaft, and a second rotating shaft is fixedly connected to the lower surface of the first rotating plate.

[0012] Preferably, a second rotating plate is rotatably connected to the outer wall of the second rotating shaft, and a third rotating shaft is rotatably connected to the inside of the second rotating plate. The upper surface of the third rotating shaft is fixedly connected to the lower surface of the fixed block.

[0013] Preferably, a positioning plate is fixedly connected to the outer wall of the fixing block, a second rotating shaft is rotatably connected inside the positioning plate, and a roller is fixedly connected to the outer wall of the second rotating shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the bidirectional threaded rod can be rotated by starting the motor or manually rotating the handle. Then, through the cooperation between the threaded block, connecting shaft one, rotating rod, connecting shaft two, connecting block, moving plate, and limiting plate, the anti-deviation component can be moved up and down, thereby adjusting the contact pressure with the belt surface. The dynamic adjustment can cope with different degrees of deviation. The conveyor in the coal mine may tilt due to uneven ground. The height range of the anti-deviation component can be flexibly adjusted through the lifting structure.

[0016] 2. In this utility model, through the mutual cooperation between motor 2, fixed block, sliding block, rotating plate 1, rotating shaft 2, rotating shaft 1, sliding block, and fixed plate, two of the threaded shafts can be driven to move back and forth. By precisely adjusting the distance between the rollers, the dynamic tension balance and deviation correction of the belt conveyor can be achieved, and the lateral displacement can be forcibly constrained.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1:

[0026] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an adjustable anti-deviation support device for a belt conveyor in a coal mine, comprising a base plate 1, a limiting plate 2 fixedly connected to the upper surface of the base plate 1, a movable plate 3 slidably connected to the outer wall of the limiting plate 2, a support plate 4 fixedly connected to the outer wall of the limiting plate 2, a motor 5 fixedly connected to the upper surface of the support plate 4, a bidirectional threaded rod 6 fixedly provided at the output end of the motor 5, a manual component 12 provided at the other end of the bidirectional threaded rod 6, the outer wall of the bidirectional threaded rod 6 rotatably connected to the inside of the limiting plate 2, a threaded block 7 threadedly connected to the outer wall of the bidirectional threaded rod 6, a connecting shaft 8 fixedly connected to the outer wall of the threaded block 7, a rotating rod 9 rotatably connected to the outer wall of the connecting shaft 8, a connecting shaft 10 rotatably connected to the inside of the rotating rod 9, a connecting block 11 fixedly connected to the outer wall of the connecting shaft 10, the upper surface of the connecting block 11 fixedly connected to the lower surface of the movable plate 3, and an anti-deviation component provided on the upper surface of the movable plate 3;

[0027] Specifically, the base plate 1 fixes the limiting plate 2, which in turn limits the movement of the moving plate 3, preventing the rotation of the bidirectional threaded rod 6 from causing the moving plate 3 to rotate. The limiting plate 2 also fixes the support plate 4, which in turn fixes the position of the supporting motor 5. When the motor 5 is started, it drives the bidirectional threaded rod 6 to rotate under the support of the limiting plate 2. The rotation of the bidirectional threaded rod 6 drives the two threaded blocks 7 to move back and forth relative to each other. The movement of the threaded blocks 7 can then drive the rotating rod 9 to rotate via the connecting shaft 8. The rotating rod 9, in turn, drives the moving plate 3 to move horizontally up and down under the support of the limiting plate 2 via the connecting shaft 10 and the connecting block 11.

[0028] Example 2:

[0029] Reference Figure 3The manual component 12 includes a locking block 1201. The outer wall of the locking block 1201 is fixedly connected to the other end of the bidirectional threaded rod 6. A handle 1202 is engaged with the outer wall of the locking block 1201. The handle 1202 is located on the outer wall of the bidirectional threaded rod 6.

[0030] Specifically, when motor 5 fails to work due to power failure or malfunction, it can be quickly switched to manual adjustment mode. By manually rotating handle 1202, the bidirectional threaded rod 6 can be rotated by the locking block 1201 under the support of the limiting plate 2. The locking block 1201 has a triangular fitting structure, which is precisely matched with the outer contour of handle 1202, so that it can be linked with handle 1202. When rotating handle 1202, torque can be transmitted through this fitting shape, so that the force of rotating handle 1202 can be accurately transmitted to bidirectional threaded rod 6, causing bidirectional threaded rod 6 to rotate. At the same time, it can lock handle 1202 to prevent slippage and ensure stable transmission of manual operating force. Thus, this embodiment can prevent the correction function from running continuously and avoid equipment downtime.

[0031] Reference Figure 1 , Figure 4 and Figure 5 The anti-deviation component includes a support block 14 and a support block 25. The lower surfaces of both support blocks 14 and 25 are fixedly connected to the lower surface of the moving plate 3. The outer walls of both support blocks 14 and 25 are fixedly connected to a fixing block 16. A motor 2 17 is fixedly connected inside the fixing block 16. A threaded shaft 18 is fixedly provided at the output end of the motor 2 17. The outer wall of the threaded shaft 18 is rotatably connected to the outer wall of the fixing block 16. A sliding block 19 is threadedly connected to the outer wall of the threaded shaft 18. A sliding groove 25 is provided inside the fixing block 16. The outer wall of the sliding block 19 is slidably connected to the inner wall of the sliding groove 25. A rotating shaft 26 is fixedly connected inside the sliding block 19. A roller 28 is rotatably connected to the outer wall of the rotating shaft 26. A fixing plate 29 is fixedly connected to the outer wall of the fixing block 16. The outer wall of the rotating shaft 26 is fixedly connected to the inside of the fixing plate 29.

[0032] Specifically, the movable plate 3 serves to fix the positions of support block 14 and support block 25. Both support block 14 and support block 25 fix the position of the fixed block 16. The fixed block 16 fixes the position of motor 2 17. Starting motor 2 17 drives the threaded shaft 18 to rotate under the support of the fixed block 16. The rotation of the threaded shaft 18 drives the threaded sliding block 19 to reciprocate. Simultaneously, the sliding block 19 fixes the two rotating shafts 26 at both ends, allowing the rotating shafts 26 to support the rotation of the roller 28. The fixed block 16 also fixes the fixed plate 29, which in turn fixes the other two rotating shafts 26. These two rotating shafts 26 then support the rotation of the other two rollers 28.

[0033] Reference Figure 4 and Figure 5 A rotating shaft 20 is fixedly connected to the lower surface of the sliding block 19. A rotating plate 21 is rotatably connected to the outer wall of the rotating shaft 20. A rotating shaft 22 is fixedly connected to the lower surface of the rotating plate 21. A rotating plate 23 is rotatably connected to the outer wall of the rotating shaft 22. A rotating shaft 24 is rotatably connected to the inside of the rotating plate 23. The upper surface of the rotating shaft 24 is fixedly connected to the lower surface of the fixed block 16. A positioning plate 13 is fixedly connected to the outer wall of the fixed block 16. A rotating shaft 27 is rotatably connected to the inside of the positioning plate 13. A roller 30 is fixedly connected to the outer wall of the rotating shaft 27.

[0034] Specifically, the rotation of the fixed block 16 can drive the threaded sliding block 19 to slide within the inner wall of the sliding groove 25 opened inside the fixed block 16. At the same time, the movement of the sliding block 19 can drive the rotating plate 21 to rotate through the rotating shaft 20. Then, the rotating plate 21 can drive the rotating plate 23 to rotate under the support of the rotating shaft 24 through the rotating shaft 22. The fixed block 16 serves to fix the position of the rotating shaft 24. The rotating plates 23 and 21 support the movement of the sliding block 19. The horizontal distance between the two rollers 28 can adjust the belt tension distribution and forcibly correct belt deviation. At the same time, the positioning plate 13 supports the rotation of the rotating shaft 27. The rotating shaft 27 fixes the position of the idler roller 30. The idler roller 30 can support the weight of the belt and materials and prevent the belt from sagging.

[0035] Working principle: When in use, the motor 5 is started first, which drives the bidirectional threaded rod 6 to rotate under the support of the limiting plate 2. Then, the rotation of the bidirectional threaded rod 6 drives the threaded block 7 to move back and forth. While the threaded block 7 is moving, it can drive the rotating rod 9 to rotate through the connecting shaft 8. The rotation of the rotating rod 9 then drives the moving plate 3 to move under the support of the limiting plate 2 through the connecting shaft 10 and the connecting block 11. This can drive the active anti-deviation component to adjust the height position and improve the correction efficiency. Similarly, the bidirectional threaded rod 6 can be driven to rotate by manually rotating the handle 1202. The locking block 1201 can limit and fix the handle 1202 to prevent it from rotating suddenly and can stably transmit the rotational force to the bidirectional threaded rod 6.

[0036] The starting motor 17 drives the threaded shaft 18 to rotate under the support of the fixed block 16. The rotation of the threaded shaft 18 drives the threaded sliding block 19 to slide within the inner wall of the sliding groove 25. While the sliding block 19 is sliding, the rotating shaft 20 drives the rotating plate 21 to rotate. The rotation of the rotating plate 21 can then drive the rotating plate 23 to rotate under the support of the rotating shaft 24. The rotation of the rotating plates 21 and 23 can stably support the movement of the sliding block 19. The movement of the sliding block 19 can drive the rotating shaft 26 fixed at both ends to move synchronously. The rotating shaft 26 then drives the two rollers 28 to move back and forth. In coal mine conveying, uneven material distribution can cause the belt to be loose or tight in some places. The reciprocating movement of the rollers 28 can compensate for the length difference in real time and maintain tension balance. At the same time, the idler rollers 30 can prevent the belt from directly rubbing against the support when rotating, reducing the edge wear rate.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
