[0001] This utility model relates to the field of bridge crane technology, specifically a positioning and anti-sway structure for bridge cranes. Background Technology

[0002] Bridge cranes are important lifting equipment widely used in factories, warehouses, logistics centers, and construction sites. They are mainly used for moving heavy objects and can significantly improve work efficiency and safety. As an important material handling equipment, bridge cranes play an irreplaceable role in modern industrial production and construction. With the development of technology, their performance is constantly improving, and more intelligent and automated designs are gradually becoming the mainstream trend.

[0003] When traditional bridge cranes are in operation, the hook of the crane will sway when lifting heavy objects. The swaying increases the risk of collision, which may lead to equipment damage or personnel injury. For operations that require precise placement of heavy objects, the swaying makes accurate positioning difficult. It is not convenient to add anti-sway structures to bridge cranes to enhance their stability during operation.

[0004] Therefore, this utility model provides a positioning and anti-sway structure for a bridge crane to solve the above problems. Utility Model Content

[0026] 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.

[0027] This utility model provides a positioning and anti-sway structure for a bridge crane, such as Figures 1-6 As shown, the positioning and anti-sway structure of the bridge crane includes a crane frame 1, with adjustment mechanisms fixedly connected to both sides of the crane frame 1. A slide rail is provided on the upper surface of the crane frame 1, and a frame rod 2 is slidably connected inside the slide rail. A stabilizing mechanism is fixedly connected to the bottom of the frame rod 2.

[0028] The stabilizing mechanism includes a connecting block 3, the upper surface of which is fixedly connected to the bottom of the support rod 2. Electric push rods 4 are fixedly connected to both sides of the bottom of the connecting block 3. One end of the electric push rod 4 is fixedly connected to the chassis 5. Threaded holes are opened on both sides of the upper surface of the chassis 5. A threaded rod 6 is threadedly connected to the inside of the threaded hole, and a nut 7 is threadedly connected to the outer surface of the threaded rod 6. Through the stabilizing mechanism, the swing range can be reduced when using the bridge crane, preventing the crane from swaying at the far end or side, improving the stability during operation. The stable structure reduces the safety risks in lifting operations, avoids cargo falling or operation errors caused by swinging, and reduces wear caused by mechanical stress and vibration by improving structural stability, thereby reducing the failure rate and maintenance frequency.

[0029] The adjustment mechanism includes a support plate 8, the inner wall of which is fixedly connected to one side of the crane frame 1. A servo motor 9 is fixedly connected to the outer surface of one of the support plates 8. A B-thread rod 10 is splinedly connected to the output end of the servo motor 9. A threaded sleeve 11 is threadedly connected to the outer surface of the B-thread rod 10. The bottom of the threaded sleeve 11 is fixedly connected to the upper surface of the frame rod 2. The adjustment mechanism adjusts the position of the stabilizing mechanism as needed, so that the stabilizing mechanisms on both sides of the bottom of the bridge crane are kept on the same horizontal line, maintaining balance and improving the stabilization effect.

[0030] Friction plate A 12 is fixedly connected to the outer surface of the frame rod 2, and friction plate B 13 is fixedly connected to the inside of the slide rail on the upper surface of the crane frame 1. When the frame rod 2 moves, friction is increased by friction plate A 12 and friction plate B 13 to prevent the threaded sleeve 11 from slipping when the crane is working, thus affecting the stability.

[0031] A chain 14 is fixedly connected to the middle of the bottom of the frame 2, and a telescopic sleeve 15 is fixedly connected to the edge of the bottom of the frame 2. The electric push rod 4 is activated according to the height of the bridge crane. The electric push rod 4 drives the chassis 5 to rise and fall and extend. When the chassis 5 extends and retracts, it drives the connecting sleeve 16 and the telescopic sleeve 15 to extend and retract. The telescopic sleeve 15 drives the internal chain 14 to extend and retract.

[0032] The bottom of the telescopic sleeve 15 is fixedly connected to the connecting sleeve 16. The bottom of the connecting sleeve 16 is fixedly connected to the middle of the upper surface of the chassis 5. When the chassis 5 extends or retracts, it drives the connecting sleeve 16 and the telescopic sleeve 15 to extend or retract. The telescopic sleeve 15 drives the internal chain 14 to extend or retract. Both the telescopic sleeve 15 and the chain 14 play a supporting role.

[0033] A flexible rope 17 is fixedly connected to the middle of the bottom of the chassis 5. One end of the flexible rope 17 is fixedly connected to a load-bearing block 18, which can increase the load-bearing effect and improve the stability.

[0034] A sleeve 19 is fixedly connected to the upper surface of the threaded sleeve 11. A telescopic rod 21 is threadedly connected to the inside of the sleeve 19 through a fixing bolt 20. A bracket 22 is fixedly connected to one end of the telescopic rod 21. The height of the bracket 22 is adjusted according to the height of the crane hook, and the telescopic rod 21 is adjusted inside the sleeve 19. After the adjustment is completed, it is reinforced with the fixing bolt 20 to facilitate the smooth operation of the crane.

[0035] Specifically, when using a bridge crane, to prevent excessive swaying during operation, stabilizing mechanisms are added to both sides of the bottom of the crane frame 1. The servo motor 9 is activated, and its rotation drives the B threaded rod 10 to rotate. The B threaded rod 10 then moves the threaded sleeve 11, which in turn moves the frame rod 2. During movement, the frame rod 2 utilizes friction plates A and B to increase friction, preventing the threaded sleeve 11 from slipping and affecting the stabilizing effect. Subsequently, the electric push rod 4 is activated according to the height of the bridge crane. The electric push rod 4 drives the chassis 5 to rise, fall, and extend. During this extension and retraction, the chassis 5 drives the connecting sleeve 16 and the telescopic sleeve 15 to extend and retract. The telescopic sleeve 15 then drives the internal chain 14 to extend and retract. Adjust the threaded rod 6 to the appropriate depth and adjust the height of the load-bearing block 18. After adjustment, fix it with nut 7 to add a stabilizing mechanism at the bottom of the crane frame 1, preventing the crane from swaying at the far end or side, improving the stability during operation. The stable structure reduces the safety risks in lifting operations and avoids cargo falling or operation errors caused by swinging. By improving structural stability, it reduces wear caused by mechanical stress and vibration, and reduces the failure rate and maintenance frequency. Then, adjust the height of the bracket 22 according to the height of the crane hook, and adjust the telescopic rod 21 inside the sleeve 19. After adjustment, reinforce it with fixing bolt 20 to facilitate the smooth operation of the crane.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
