Description

Technical Field

[0001] This utility model relates to the field of mechanical positioning technology, and in particular to an auxiliary device for hoisting and positioning prefabricated components. Background Technology

[0002] Traditional prefabricated component hoisting and positioning auxiliary devices are typically used for precise positioning and fixing of prefabricated components in building construction. They are widely used in the construction of high-rise buildings, bridges, industrial plants, and other fields. Since their working principle is based on the precise coordination of mechanical structures, the positioning and fixing of components are achieved through steps such as clamping, locking, and guiding. Therefore, the flexibility, positioning accuracy, and ease of maintenance of the device have become key factors in improving construction efficiency and quality. Most existing traditional hoisting and positioning auxiliary devices adopt relatively complex fixed structures. Although they can meet basic positioning requirements, they have certain shortcomings in terms of the flexibility of changing the grippers.

[0003] Existing traditional hoisting positioning auxiliary devices have some shortcomings in positioning effect. Traditional positioning pins usually rely on manual operation for locking and unlocking, which is cumbersome and time-consuming and easily affected by human factors. After the hoisting operation is completed, the resetting operation of the positioning pins is complicated and requires manual intervention, which increases construction costs and safety risks.

[0004] In the existing technology, the auxiliary device for hoisting and positioning prefabricated components has some shortcomings in the replacement and maintenance of the grippers. The existing gripper system adopts a fixed structure, which makes it difficult to disassemble and replace the grippers. This design makes the maintenance work complicated and time-consuming, unable to adapt to different needs, and leads to increased costs. During long-term use, the grippers are prone to wear or failure, which affects the normal operation of the device and thus affects the construction progress. Therefore, an improved auxiliary device for hoisting and positioning prefabricated components is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary device for hoisting and positioning prefabricated components, which aims to improve the problem that the maintenance of positioning auxiliary devices is complicated and time-consuming, unable to adapt to different needs, and thus increases costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for hoisting and positioning prefabricated components, including a bracket, a second load-bearing plate fixedly connected to the outer wall of the bracket, a first connecting column rotatably connected inside the second load-bearing plate, a pin slidably connected inside the first connecting column, a first limit column slidably connected to the outer wall of the pin, and a fixing component provided on one side of the outer wall of the second load-bearing plate.

[0007] The fixing component includes a protective cover, which is disposed on one side of the outer wall of the load-bearing plate 2. One end of the connecting column 1 is fixedly connected to a limiting plate. The limiting plate is slidably connected to the connecting column 2. One end of the connecting column 2 is fixedly connected to a connecting plate. The outer wall of the protective cover is fixedly connected to the outer wall of the connecting plate. The outer wall of the protective cover is fitted with a clamping claw.

[0008] Furthermore, load-bearing plates three are fixedly connected to both sides of the outer wall of the bracket, and a limit component is provided at the bottom of the load-bearing plates three.

[0009] Furthermore, the limiting component includes a positioning pin, which is disposed at the bottom of the load-bearing plate three. A limiting post two is fixedly connected to the bottom of the load-bearing plate three. The positioning pin is rotatably connected to the outer wall of the limiting post two. A connecting post three is fixedly connected to the top of the positioning pin. A spring is sleeved on the outer wall of the connecting post three. One end of the spring is fixedly connected to the inside of the load-bearing plate three.

[0010] Furthermore, the limiting plate is provided with a sliding groove for the second connecting column to slide.

[0011] Furthermore, the positioning pin is provided with a groove for the sliding of the second limiting post.

[0012] Furthermore, a load-bearing plate is fixedly connected to the outer wall of the bracket.

[0013] Furthermore, a connecting ring is fixedly connected to one top of the load-bearing plate.

[0014] Furthermore, the second load-bearing plate is provided with a sliding groove for the first connecting column to slide.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pulling out the pin in the first connecting column, the fixing of the first connecting column is removed. The first connecting column is rotated to drive the groove on the limiting plate to move the second connecting column inside it, thereby driving the two connecting plates connected to it to move, and finally driving the two protective covers to move to remove the fixing of the gripper, which facilitates its replacement and improves the convenience of gripper replacement. This allows the device to adapt to different application scenarios and enhances the practicality of the device.

[0017] 2. In this utility model, the positioning pin stops moving when it reaches the designated groove under the action of the connecting column three and the spring, thus achieving rapid positioning. When the hoisting is finished, it only needs to be moved downwards. Under the combined action of the connecting column three and the spring, the positioning pin will rotate upwards around the limiting column two and return to its original state, which is convenient for the next use. No manual operation is required, thus improving the positioning efficiency of the device. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of an auxiliary device for hoisting and positioning prefabricated components, including a bracket 1. The bracket 1 connects the entire device to ensure its integrity. A load-bearing plate 2 5 is fixedly connected to the outer wall of the bracket 1. The load-bearing plate 2 5 connects the entire fixing assembly and serves as a connection. A connecting column 1 8 is rotatably connected inside the load-bearing plate 2 5. The rotation of the connecting column 1 8 drives the limiting plate 11, which indirectly drives the connecting column 2 12 to move. A pin 6 is slidably connected inside the connecting column 1 8. The pin 6 cooperates with the limiting column 1 7 to fix the connecting column 1 8. The limiting column 1 7 is slidably connected to the outer wall of the pin 6. The limiting column 1 7 has a groove inside to limit the pin 6. A fixing assembly is provided on one side of the outer wall of the load-bearing plate 2 5.

[0027] The fixing component includes a protective cover 9, which is set on one side of the outer wall of the load-bearing plate 2 5. The two protective covers 9 are tightly fitted together to fix the gripper 4. One end of the connecting column 1 8 is fixedly connected to a limiting plate 11. The rotation of the limiting plate 11 drives the connecting column 2 12 to move, indirectly changing the position of the protective cover 9. The connecting column 2 12 is slidably connected inside the limiting plate 11. The connecting column 2 12 moves with the limiting plate 11, driving the connecting plate 10 to move. One end of the connecting column 2 12 is fixedly connected to the connecting plate 10. The connecting plate 10 moves with the connecting column 2 12, driving the protective cover 9 to move. The outer wall of the protective cover 9 is fixedly connected to the outer wall of the connecting plate 10. The gripper 4 is fitted to the outer wall of the protective cover 9. The gripper 4 can rotate around the protective cover 9 to clamp the object.

[0028] Reference Figure 4 and Figure 5 Both sides of the outer wall of bracket 1 are fixedly connected to load-bearing plates 3 13. Load-bearing plates 3 13 connect the entire limiting assembly and serve a connecting function. A limiting assembly is set at the bottom of load-bearing plates 3 13, including a positioning pin 14. The positioning pin 14 can be inserted into the groove of an object to achieve quick positioning. The positioning pin 14 is located at the bottom of load-bearing plates 3 13. A limiting post 2 17 is fixedly connected to the bottom of load-bearing plates 3 13. The limiting post 2 17 facilitates the rotation of the positioning pin 14 and can change the angle of the positioning pin 14. The positioning pin 14 is rotatably connected to the outer wall of the limiting post 2 17. A connecting post 3 16 is fixedly connected to the top of the positioning pin 14. The connecting post 3 16 slides inside the load-bearing plates 3 13 to assist the positioning pin. 14. Changing the angle, a spring 15 is sleeved on the outer wall of the connecting column 3 16. The spring 15 is elastic, ensuring that the positioning pin 14 can return to its original state after being fixed and achieve automatic disengagement. One end of the spring 15 is fixedly connected to the inside of the load-bearing plate 3 13. The limiting plate 11 is provided with a sliding groove for the connecting column 2 12 to slide. The positioning pin 14 is provided with a sliding groove for the limiting column 2 17 to slide. The outer wall of the bracket 1 is fixedly connected to the load-bearing plate 1 2. The load-bearing plate 1 2 connects the bracket 1 and the connecting ring 3, and plays a connecting role. The top of the load-bearing plate 1 2 is fixedly connected to the connecting ring 3. The connecting ring 3 is hollow inside and can be connected to the hoisting device through it. The inside of the load-bearing plate 2 5 is provided with a sliding groove for the connecting column 1 8 to slide.

[0029] Working Principle: When a prefabricated component hoisting and positioning auxiliary device is needed, it is first connected to the hoisting device via the connecting ring 3. The clamp 4 is then replaced with the appropriate one according to the actual requirements. The fixing of the connecting column 8 is removed by pulling out the pin 6 in the connecting column 8. Rotating the connecting column 8 causes the limiting plate 11 to rotate. The groove in the limiting plate 11 allows the connecting column 12 to move inside, causing the two connecting plates 10 connected to it to move, ultimately moving the two protective covers 9 to remove the fixing of the clamp 4. After replacing the clamp 4, the above operation is reversed to complete the fixing. This allows the device to adapt to different needs. During positioning, the positioning pin 14 stops moving when it reaches the designated groove under the action of the connecting column 16 and the spring 15, accelerating the positioning efficiency. At the end of the hoisting, simply move it downwards. Under the combined action of the connecting column 16 and the spring 15, the positioning pin 14 will rotate upwards around the limiting column 17, restoring its original shape for future use. This device not only meets more application scenarios but also provides rapid positioning without manual intervention, accelerating hoisting efficiency and improving the practicality and flexibility of the device.
