[0010] Preferably, two sets of curved plates are fixedly connected to the upper part of the upper mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model allows the chains on both sides of the electric hoist assembly to descend between the limiting plates of the two fixed rods. The second motor drives the inner lifting rod, thereby causing the second threaded platform to rotate along the inside of the outer lifting cylinder, thus changing the descent distance of the lower mounting plate and ensuring that the lower mounting plate can descend to a suitable distance when the chain is at its lowest point. When the chain swings left and right, the limiting plates on both sides are pushed, thereby compressing and stretching the second damping rod and the second spring on both sides, which buffers the swing on both sides. When the chain swings back and forth, the fixed rod is pushed, and the mounting rod drives the moving block to compress and stretch the first spring and the first damping rod, which buffers the vibration back and forth. It can buffer the swaying of the lowered chain at a suitable position in all directions, effectively reducing the shaking of the overall equipment.

[0013] 2. This utility model also uses a first motor to drive a first rotating rod on one side, and a reversing gear to drive a second rotating rod to rotate in the opposite direction. A transmission belt drives the first rotating rod on the other side to rotate. A rotating arm changes the extension distance of the fixed rod, thereby allowing the fixed rod to straighten the chain. By rotating the sleeve rod, the first threaded platform rotates inside the mounting rod, changing the extension distance of the sleeve rod. The mounting plate makes the limiting plates on both sides of the chain tightly attached. The buffer assembly is tightly attached to the chain according to the model of the electric hoist, improving the versatility of the equipment. Attached Figure Description

Detailed Implementation

[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 Figure 1-4This utility model provides a technical solution: an anti-sway control system for a bridge crane, including a lower mounting plate 1. Four sets of first rotating plates 2 are fixedly welded to the outer side of the lower mounting plate 1. A first rotating rod 3 is rotatably installed between the two first rotating plates 2. Rotating arms 4 are fixedly welded to the outer sides of both ends of the first rotating rod 3. A rotating block 5 is rotatably installed inside the other end of the rotating arm 4. An installation block 6 is fixedly welded to the lower part of the rotating block 5. A moving block 7 is slidably installed inside the two mounting blocks 6 facing each other on one side. A first damping rod 8 is threaded between the moving block 7 and the inner wall of the mounting block 6. A first spring 9 is sleeved on the outer side of the first damping rod 8. The two ends of the first spring 9 are fixedly welded to the inner walls of the moving block 7 and the mounting block 6. An installation rod 10 is fixedly welded to one end of the moving block 7. A fixing rod 11 is fixedly welded between the two mounting rods 10. Two sets of mounting plates 17 are fitted together. Two sets of second damping rods 15 are threadedly installed on one side of the mounting plates 17 facing each other. A limiting plate 14 is fixedly welded to the other end of the second damping rod 15. The limiting plate 14 is slidably installed on the outside of the fixed rod 11. A second spring 16 is fitted on the outside of the second damping rod 15. The two ends of the second spring 16 are fixedly welded to the mounting plate 17 and the limiting plate 14. The chains on both sides of the electric hoist assembly are passed between the limiting plates 14 of the fixed rods 11 on both sides. When the chain swings left and right, the limiting plates 14 on both sides are pushed, thereby compressing and stretching the second damping rods 15 and the second spring 16 on both sides, which buffers the swing on both sides. When the chain swings back and forth, the fixed rod 11 is pushed, and the mounting rod 10 drives the moving block 7 to compress and stretch the first spring 9 and the first damping rod 8, which buffers the vibration back and forth.

[0021] A second rotating plate 22 is fixedly welded to both sides of the lower mounting plate 1. A second rotating rod 23 is rotatably mounted on the second rotating plate 22. A matching reversing gear 24 is fixedly welded to the outer side of the middle of the second rotating rod 23 and the first rotating rod 3 on one side. A transmission belt 25 is sleeved on the outer side of the second rotating rod 23 and the first rotating rod 3 on the other side. A first motor 26 is mounted on the outer flange of the first rotating plate 2 on one side. The first motor 26 is connected to the first rotating rod 3 by a coupling. The first motor 26 drives the first rotating rod 3 on one side, drives the second rotating rod 23 to rotate in the opposite direction through the reversing gear 24, drives the first rotating rod 3 on the other side to rotate through the transmission belt 25, and changes the extension distance of the fixed rod 11 by the rotating arm 4. This allows the fixing rod 11 to straighten the chain. A first threaded platform 12 is threaded inside the mounting rod 10. A sleeve rod 13 is fixedly welded to one side of the first threaded platform 12. The first threaded platform 12 and the sleeve rod 13 are fitted onto the outside of the fixing rod 11. The other end of the sleeve rod 13 penetrates the mounting rod 10 and is fixedly welded to the mounting plate 17. By rotating the sleeve rod 13, the first threaded platform 12 rotates inside the mounting rod 10, changing the extension distance of the sleeve rod 13. The mounting plate 17 ensures that the limiting plates 14 on both sides are tightly against both sides of the chain. A first balance bar 18 is slidably installed inside the mounting block 6. A balance plate 19 is fixedly welded to the other end of the first balance bar 18. Second balance bars 20 are fixedly welded to both sides of the lower mounting plate 1. The second balance bar 20 has balance grooves 21 on both sides. The balance plate 19 is slidably installed inside the balance groove 21. When the rotating arm 4 rotates, the mounting block 6 moves up and down. The balance plate 19 moves up and down along the balance groove 21, thereby causing the first balance bar 18 to move up and down horizontally, thus ensuring that the mounting block 6 remains horizontal. An outer lifting cylinder 27 is fixedly welded to the upper middle part of the lower mounting plate 1. A second threaded platform 28 is threaded inside the outer lifting cylinder 27. An inner lifting rod 29 is fixedly welded to the upper part of the second threaded platform 28. An upper mounting plate 30 is rotatably installed on the upper part of the inner lifting rod 29. A second motor 31 is installed on the upper flange of the upper mounting plate 30. The second motor 31 is connected to the inner lifting rod 29 by a coupling. 31 drives the inner lifting rod 29, thereby causing the second threaded platform 28 to rotate inside the outer lifting cylinder 27, thus changing the descent distance of the lower mounting plate 1, ensuring that the lower mounting plate 1 can descend to a suitable distance when the chain is below, thereby ensuring that the component can buffer the swaying of the chain. Four sets of inner connecting rods 32 are fixedly welded to the lower part of the upper mounting plate 30, and outer connecting rods 33 are slidably installed on the outside of the inner connecting rods 32. The lower part of the outer connecting rods 33 is fixedly welded to the lower mounting plate 1 to ensure a reliable connection between the lower mounting plate 1 and the upper mounting plate 30. Two sets of bent plates 34 are fixedly welded to the upper part of the upper mounting plate 30. The equipment is installed at the lower part of the electric hoist through the bent plates 34 to realize the connection between the equipment and the crane.

[0022] Working principle: In use, the device is installed at the lower part of the electric hoist via the curved plate 34. The chains on both sides of the electric hoist assembly are lowered between the limiting plates 14 of the two fixing rods 11. The first motor 26 drives the first rotating rod 3 on one side, which drives the second rotating rod 23 to rotate in the opposite direction via the reversing gear 24. The transmission belt 25 drives the first rotating rod 3 on the other side to rotate. The extension distance of the fixing rod 11 is changed by the rotating arm 4, so that the fixing rod 11 can straighten the chain. By rotating the sleeve rod 13, the first threaded platform 12 is driven to rotate inside the mounting rod 10, changing the extension distance of the sleeve rod 13. The mounting plate 17 makes the two side limiting plates 14 fit tightly against both sides of the chain. The second motor 31 drives the inner lifting rod 29, thereby driving the second threaded platform 28 to rotate along the inside of the outer lifting cylinder 27, thereby changing the descent distance of the lower mounting plate 1 and ensuring that the lower mounting plate 1 can descend to a suitable distance when the chain is below. When the chain swings left and right, by pushing the two side limiting plates 14, the second damping rod 15 and the second spring 16 on both sides are compressed and stretched, which buffers the swing on both sides. When the chain swings back and forth, by pushing the fixed rod 11, the mounting rod 10 drives the moving block 7 to compress and stretch the first spring 9 and the first damping rod 8, which buffers the vibration back and forth.
