[0029] Specifically, the adjustment mechanism includes two groups of support frames 12, and sliders 8 are fixedly installed on adjacent sides of the two groups of support frames 12. A slide groove 7 is arranged under the frame 1, and the slide groove 7 and the slider 8 are slidably connected. A driving structure is arranged between the two groups of sliders 8, and the support frames 12 are connected to the fixed plate 11 through the adjustment structure.
[0030] Specifically, the driving structure includes a threaded rod 9, which is rotatably inserted into the interior of the frame 1, the threaded rod 9 and the slider 8 are threadedly connected, and a motor 10 is fixedly installed at one end of the threaded rod 9, and the motor 10 and the frame 1 are fixedly connected.
[0031] Place the frame 1 above the crossbeam 4, with the roller 6 in contact with the upper surface of the crossbeam 4, connect the motor 10 to an external power source, and the motor 10 drives the threaded rod 9 to rotate. Since the threaded rod 9 and the slider 8 are threadedly connected, the threaded rod 9 can drive the two groups of sliders 8 to move closer to or away from each other inside the slide groove 7, and the slider 8 drives the support frame 12 to move synchronously. When the two groups of support frames 12 approach each other, they drive the push plate 17 to move toward the direction of the crossbeam 4.
[0032] Specifically, a connecting rod 14 is fixedly inserted inside the cavity 13 , and the connecting rod 14 is slidably connected to the support frame 12 . A No. 1 spring 15 is movably sleeved outside the connecting rod 14 , and the No. 1 spring 15 is fixedly connected to the support frame 12 .
[0033] The fixing plate 11 can be raised and lowered in the cavity 12 opened inside the support frame 12 . At this time, the fixing plate 11 slides outside the connecting rod 14 , and the No. 1 spring 15 is deformed by the force.
[0034] Furthermore, the moving mechanism includes a mounting plate 18, which is rotatably mounted on the side of the push plate 17 away from the fixed plate 11. Rollers 22 are installed on the upper and lower ends of the mounting plate 18 through a lifting assembly.

[0035] The push plate 17 can rotate with the rotating shaft 16 as the center. The two groups of push plates 17 are separated from each other at one end close to the cross beam 4, so that the two groups of mounting plates 18 are separated from each other. The two groups of mounting plates 18 slide outside the cross bar 19. At this time, the No. 2 spring 20 is deformed by the force.
[0036] Specifically, the lifting assembly includes a rod 21, which is fixedly mounted at the upper and lower ends of the mounting plate 18, and a roller 22 is movably sleeved at one end of the rod 21 away from the mounting plate 18. The outer sleeve of the rod 21 is provided with a No. 3 spring 23, and the No. 3 spring 23 and the roller 22 are fixedly connected.
[0037] The lifting assembly includes a fixed block 24, which is fixedly installed below the roller 22. A roller 26 is provided on the side of the mounting plate 18 away from the push plate 17. The roller 26 is in contact with the beam 4. A mounting block 25 is rotatably installed above the roller 26. The end of the mounting block 25 away from the roller 26 is rotatably connected to the fixed block 24.
[0038] The push plate 17 drives the moving mechanism to move to the inside of the groove 5. When the roller 26 contacts the beam 4, the push plate 17 drives the mounting plate 18 to continue to move. The mounting plate 18 approaches the direction of the roller 26. With the cooperation of the fixed block 24 and the mounting block 25, the mounting block 25 pushes the fixed block 24 to move away from the mounting plate 18. The mounting block 25 drives the roller 22 to move synchronously on the outside of the rod 21. At this time, the No. 3 spring 23 is deformed by the force.
[0039] Furthermore, the coating mechanism includes a mounting frame 27 , a brush 28 is disposed inside the mounting frame 27 , the brush 28 is connected to the push plate 17 via a sliding structure, and a material discharge structure is disposed above the brush 28 .
[0040] Specifically, the sliding structure includes a support block 29, a guide groove 30 is opened inside the mounting frame 27, the guide groove 30 and the support block 29 are slidably connected, a groove body 32 is opened inside the mounting frame 27, a protrusion 31 is slidably installed inside the groove body 32, and the protrusion 31 is fixedly connected to the push plate 17.
[0041] The end of the push plate 17 away from the mounting plate 18 can drive the protrusion 31 to move, and the protrusion 31 moves inside the groove body 32, thereby driving the support block 29 to slide inside the guide groove 30, and the support block 29 drives the brush 28 to move, and the two groups of brushes 28 approach each other, and the wire rope 3 passes between the two groups of brushes 28.
[0042] The material discharge structure includes a transverse plate 33, which is fixedly installed above the mounting frame 27, a material storage box 34 is fixedly installed above the transverse plate 33, a material discharge pipe 35 is fixedly installed below the material storage box 34, and a sealing plate 36 is fixedly installed between the two groups of support blocks 29, and the sealing plate 36 is in contact with the material discharge pipe 35.
[0043] Lubricating oil is stored inside the storage box 34. In the initial state, the sealing plate 36 is below the discharge pipe 35, and the lubricating oil cannot flow out. When the two groups of brushes 28 approach each other, the support block 29 drives the sealing plate 36 to move. At this time, the sealing plate 36 and the discharge pipe 35 are separated, and the lubricating oil inside the storage box 34 can intermittently drip onto the top of the brush 28.
[0044] Working principle: Place the frame 1 above the beam 4, the roller 6 is in contact with the upper surface of the beam 4, connect the motor 10 to the external power supply, and the motor 10 drives the threaded rod 9 to rotate. Since the threaded rod 9 and the slider 8 are threadedly connected, the threaded rod 9 can drive the two groups of sliders 8 to approach or move away from each other inside the slide groove 7. The slider 8 drives the support frame 12 to move synchronously. When the two groups of support frames 12 approach each other, they drive the push plate 17 to move toward the direction of the beam 4.
[0045] The push plate 17 drives the moving mechanism to move to the inside of the groove 5. When the roller 26 contacts the beam 4, the push plate 17 drives the mounting plate 18 to continue to move. The mounting plate 18 approaches the direction of the roller 26. With the cooperation of the fixed block 24 and the mounting block 25, the mounting block 25 pushes the fixed block 24 to move away from the mounting plate 18. The mounting block 25 drives the roller 22 to move synchronously on the outside of the rod 21. At this time, the No. 3 spring 23 is deformed by the force.
[0046] At the same time, the push plate 17 can rotate with the rotating shaft 16 as the center, and the two groups of push plates 17 close to the end of the beam 4 move away from each other, so that the two groups of mounting plates 18 move away from each other, and the two groups of mounting plates 18 slide on the outside of the cross bar 19. At this time, the No. 2 spring 20 is deformed by the force.
[0047] At the same time, the end of the push plate 17 away from the mounting plate 18 can drive the protrusion 31 to move, and the protrusion 31 moves inside the groove body 32, thereby driving the support block 29 to slide inside the guide groove 30, and the support block 29 drives the brush 28 to move, and the two groups of brushes 28 approach each other, and the wire rope 3 passes between the two groups of brushes 28. When the drum 2 is winding and unwinding the wire rope 3, the brush 28 can clean the wire rope 3, and at the same time can ensure that the position of the wire rope 3 will not change with winding and unwinding, which is beneficial to increase the stability when carrying objects.
[0048] Furthermore, lubricating oil is stored inside the storage box 34. In the initial state, the sealing plate 36 is below the discharge pipe 35, and the lubricating oil cannot flow out. When the two groups of brushes 28 approach each other, the support block 29 drives the sealing plate 36 to move. At this time, the sealing plate 36 and the discharge pipe 35 are separated, and the lubricating oil inside the storage box 34 can intermittently drip onto the top of the brush 28, so that the brush 28 can apply the lubricating oil to the surface of the wire rope 3.
