Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hoisting hook for prefabricated components with an adjustable angle. Background Technology

[0002] Precast components are building parts, such as beams, slabs, and columns, that are prefabricated in a factory or on-site. Due to their large size and weight, they require lifting hooks for precise transport to designated locations for construction. Adjustable lifting hooks allow for flexible adjustment of the angle of precast components during transport to meet the needs of different construction scenarios, ensuring accurate installation and improving construction efficiency and safety.

[0003] An adjustable-angle precast component hoisting hook typically consists of a hook body, connecting components, an angle adjustment device, and stabilizing accessories. The hook body is directly used to hook the precast component and is often forged from high-strength steel to ensure load-bearing capacity. The connecting components are responsible for connecting to the hoisting equipment to achieve power transmission. The angle adjustment device is the core component and commonly includes a hydraulic telescopic rod, a rotatable joint, and a matching control mechanism to achieve precise angle adjustment. Stabilizing accessories, such as anti-derailment locks and reinforcing ribs, ensure the stability and safety of the connection between the hook and the component during hoisting, preventing accidents.

[0004] In existing technologies, the installation of some adjustable-angle precast component hoisting hooks takes too long, which delays construction and directly slows down the overall construction pace, preventing subsequent procedures from being carried out on time, resulting in project delays and increased time costs. Therefore, an adjustable-angle precast component hoisting hook is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an adjustable-angle prefabricated component hoisting hook, comprising a housing 1, which protects the internal installation and disassembly assembly and stabilizes its internal structure. Motors 2 are fixedly connected to both the front and rear sides of the housing 1. A rotating rod 3 is fixedly connected to the drive end of the motor 2, and a gear 4 is fixedly connected to the rear side of the rotating rod 3. The motor 2 is the driving source for the entire installation and disassembly assembly, thereby driving the rotating rod 3 to rotate, which in turn causes the gear 4 to rotate. Multiple guide plates 5 are fixedly connected to the inner wall of the housing 1. A rack 6 is fixedly and slidably connected to the adjacent side of every two guide plates 5. The guide plates allow the rack 6 to move linearly and stabilize it, while the rack 6 receives the rotation of the gear 4. Force is applied to the rack 6, which moves along with the rack 6. A moving plate 7 is fixedly connected to the left side of the rack 6. The moving plate 7 moves along with the rack 6. A force-applying plate 8 is fixedly connected to the top of the moving plate 7. The force-applying plate 8 moves along with the top of the moving plate 7. A force-receiving plate 9 is slidably connected to the top of the force-applying plate 8. The force-receiving plate 9 receives the force transmitted by the force-applying plate 8 and moves accordingly. A limit rod 10 is fixedly connected to the right side of the force-receiving plate 9. The limit rod 10 moves along with the moving plate 9. A fixed rod 11 is slidably connected to the bottom of the outer shell 1. The fixed rod 11 slides inside the outer shell 1 and is limited by the limit rod 10. An adjustment component for adjusting the angle of the hook is fixedly connected to the bottom of the fixed rod 11.

[0033] Reference Figure 2 and Figure 4 The adjustment component includes a protective cover 12, the top of which is fixedly connected to the bottom of a fixed rod 11. The protective cover 12 protects the internal angle adjustment component and stabilizes it. A second motor 14 is fixedly connected to the front of the protective cover 12. A second rotating rod 15 is fixedly connected to the drive end of the second motor 14. The second motor 14 drives the adjustment component, causing the second rotating rod 15 to rotate. Two fixed blocks 16 are fixedly connected to the bottom of the second rotating rod 15. A connecting plate 17 is fixedly connected to the bottom of each of the two fixed blocks 16. A hanging piece 18 is fixedly connected to the bottom of the connecting plate 17. The fixed blocks 16 rotate with the rotation of the second rotating rod 15, thereby driving the connecting plate 17 to rotate. The hanging piece 18 rotates with the connecting plate 17.

[0034] Reference Figures 1 to 3 A connecting rod 23 is fixedly connected to the top of the outer casing 1. The connecting rod 23 connects the equipment and the outer casing 1, allowing the equipment to move the outer casing 1. The outer side of the rack 6 meshes with the outer side of the gear 4. The gear 4 rotates, transmitting rotational force to the rack 6, causing it to move linearly. The outer side of the rotating rod 3 is rotatably connected to the inner wall of the outer casing 1. The rotating rod 3 receives the rotational force from the motor 2, thus rotating. The outer side of the moving plate 7 is slidably connected to the rear side of the guide plate 5. The moving plate 7 receives the moving force of the rack 6, thus moving. Two isolation plates 24 are fixedly connected to the inner wall of the outer casing 1. The isolation plates 24 limit the movement of the two adjusting components and provide a moving place for the fixed rod 11. The inner wall of the moving plate 7 is slidably connected to the isolation plates. Inside 24, the movable plate 7 receives guidance from the isolation plate 24. The top of the force plate 9 is fixedly connected to the fixed plate 20. The inner wall of the outer shell 1 is fixedly connected to two guide plates 19. The top of the fixed plate 20 is slidably connected to the inside of the guide plates 19. The fixed plate 20 moves with the force plate 9. The guide plates 19 allow the fixed plate 20 to move linearly. The right side of the fixed plate 20 is fixedly connected to the telescopic rod 22. The outside of the telescopic rod 22 is provided with a spring 21. The spring 21 and the telescopic rod 22 receive the moving force of the fixed plate 20, thereby moving. The top of the rotating rod 15 is rotatably connected to the limit plate 13. The top of the limit plate 13 is fixedly connected to the top inner wall of the protective cover 12. The limit plate 13 limits the rotation of the rod to prevent excessive rotation.

[0035] Working principle: Motor 2 rotates its rotating rod 3, which in turn drives the rack 6 to move. The moving plate 7 moves with the rack 6, which in turn drives the force plate 8 to move. The force plate 8 pushes the receiving plate 9, which in turn moves the limiting rod 10. At this time, the receiving plate 9 drives the fixed plate 20 to move, causing the spring 21 and the telescopic rod 22 to extend and retract. This fixes the fixed rod 11 to the limiting rod 10, thus realizing the rapid installation of the precast component hoisting hook. In addition, it can greatly reduce the installation time and put it into use quickly, thereby accelerating the overall construction rhythm and making the project process more compact and efficient.

[0036] When motor 2 reverses and moving plate 7 retracts, spring 21 and telescopic rod 22 apply force to return fixed plate 20 to its original position, thereby returning limit rod 10 to its original position and thus disengaging from control of limit rod 10.

[0037] When motor 14 drives rotating rod 15 to rotate, rotating rod 15 drives fixed block 16 to rotate, fixed block 16 drives connecting plate 17 to rotate, and hanging part 18 rotates accordingly, thereby realizing the angle adjustment of the lifting hook. In addition, it can flexibly adapt to prefabricated components of different shapes and placement angles, improve the accuracy of lifting operations, and avoid collision damage caused by angle deviation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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.
