Description

Technical Field

[0001] This utility model relates to the field of precast floor slab technology, specifically to a hoisting structure for precast floor slabs. Background Technology

[0002] Precast floor slabs refer to concrete slabs that are prefabricated in a factory or prefabrication yard, formed through standardized production processes, and then transported to the construction site for installation.

[0003] When workers are constructing precast floor slabs, they often need to use a hoisting machine to lift the slabs. During the hoisting process, hooks are usually used to fix the inner cavity of the precast floor slab before the hoisting machine is started to lift it. During the hoisting process, the hooks may come loose, which may pose a certain danger to the lives of the workers. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting structure for precast floor slabs to solve the problems existing in the background art.

[0010] Preferably, gaskets are installed on both sides of the limiting plates on both sides, and the gaskets are made of arc-shaped rubber material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention relates to a system where, during the hoisting of floor slabs by workers, applying force to the top transmission plate causes the bottom transmission plate to limit the movement of the hook within the floor slab's interior, preventing the hook from detaching during hoisting and ensuring worker safety. The transmission rod, fixing block, and fixing rod move the limiting plate to both sides, preventing the hook from shifting within the floor slab's interior and causing the floor slab to tilt during hoisting. The reset component allows workers to easily remove the hook from the floor slab's interior. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-5As shown, a hoisting structure for a precast floor slab includes a hoisting machine 1 and a hook 2 fixed to the bottom of the rope of the hoisting machine 1. A connecting rod 3 is slidably connected through the surface of the hook 2. Both ends of the connecting rod 3 are fixedly connected to a transmission plate 5. A reset assembly 4 is provided on the surface of the connecting rod 3. The reset assembly 4 includes a fixing plate 42 sleeved and fixed on the surface of the connecting rod 3. A spring 41 is sleeved on the surface of the connecting rod 3. A groove 43 is opened on the top of the surface of the hook 2. The two ends of the spring 41 are fixed to the bottom of the fixing plate 42 and the inner cavity of the groove 43, respectively. During the process of the hoisting machine 1 hoisting the floor slab through the hook 2, the floor slab will squeeze the spring 41 through the transmission plate 5 and the fixing plate 42. After the hoisting machine 1 hoists the floor slab to the designated position, the spring 41 will drive the transmission plate 5 and the fixing plate 42 to reset through its own elastic force, so that the workers can easily remove the hook 2 from the inner cavity of the floor slab.

[0016] Both sides of the bottom of the upper transmission plate 5 are hinged with transmission rods 6, and the bottom of the transmission rods 6 is hinged with fixed blocks 7. The upper and lower sides of one end of the fixed block 7 are provided with sliding grooves 12. The sliding block 13 is slidably connected inside the sliding groove 12. The sliding block 13 is fixed to the fixed plate 8. When the fixed block 7 is driven to move on the surface of the fixed plate 8 by the transmission rods 6, the fixed block 7 can be moved on the surface of the fixed plate 8 by the setting of the sliding block 13 and the sliding groove 12. At the same time, the fixed block 7 can also be limited. Both sides of the hook 2 are fixedly connected with fixed plates 8. The fixed plates 8 and the fixed blocks 7 are slidably connected. One side of the fixed block 7 is hinged with a fixed rod 9. Both sides of the hook 2 are hinged with limit plates 10. The limit plates 10 are hinged to the fixed rod 9.

[0017] Both transmission plates 5 on both sides are arc-shaped, and the distance between the two transmission plates 5 is smaller than the diameter of the hole at the outer end of the floor slab. When the workers hoist the floor slab using the hoisting machine 1, the surface of the transmission plate 5 can fit into the inner cavity of the floor slab, thereby preventing the floor slab from falling off during the hoisting process.

[0018] The outer surface of the transmission plate 5 is provided with a number of anti-slip protrusions, and the anti-slip protrusions are evenly arranged on the surface of the transmission plate 5. By setting the anti-slip protrusions, the friction force when the transmission plate 5 contacts the inner cavity of the floor slab can be increased, thereby improving the stability of the hook 2.

[0019] Both sides of the limiting plates 10 are equipped with gaskets 11. The gaskets 11 are made of arc-shaped rubber material. When the transmission plate 5 moves downward, the limiting plates 10 and gaskets 11 will move through the transmission rod 6, the fixing block 7 and the fixing rod 9. At this time, the gaskets 11 are in contact with the inner cavity of the floor slab and limit the hook 2, which can prevent the hook 2 from shifting in the inner cavity of the floor slab.

[0020] It is worth noting that the technical features proposed in this technical solution, such as the hoist 1 and the hook 2, should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0021] Working Principle: When workers use hoisting machine 1 to hoist the floor slab, they first need to insert hooks 2 into the inner cavities on both sides of the floor slab. Then, hoisting machine 1 is started to hoist the floor slab. As hoisting machine 1 applies upward force to hooks 2, the floor slab is lifted. When the upper transmission plate 5 contacts the inner cavity of the floor slab, it exerts a downward force on the upper transmission plate 5. This force, through connecting rod 3, drives the lower transmission plate 5 downward, causing it to contact the bottom of the inner cavity of the floor slab. This prevents the hooks from detaching and ensures the safety of workers. As the upper transmission plate 5 moves downward... The movement will apply force to the transmission rod 6. Since the transmission rod 6 is in an inclined state, it will generate a pushing force on the fixing block 7 and drive the fixing block 7 to slide on the surface of the fixing plate 8. When the fixing block 7 moves, it will apply force to the limiting plate 10 through the fixing rod 9, causing the limiting plate 10 to deflect outward, further limiting the inner cavity of the floor slab. After the hoisting is completed, the hook 2 will be unloaded. At this time, the spring 41 will drive the connecting rod 3, the fixing plate 42 and the transmission plate 5 to reset through its own elastic force, so that the staff can easily remove the hook 2 from the inner cavity of the floor slab for the next use.
