Description
Technical Field
[0001] This utility model relates to the field of engineering technology, specifically to a hoisting equipment for prefabricated engineering construction. Background Technology
[0002] In the fields of building construction and large equipment installation, hoisting is a crucial and widely used operation method. It is a general term for the precise installation and positioning of various equipment with the hoisting mechanism as the core. This process involves the coordinated operation of a variety of professional tools. By skillfully using the special lifting tools equipped with various hoisting equipment, heavy equipment, a large amount of building materials and other heavy objects are lifted smoothly from the ground and moved to their designated installation positions according to the predetermined plan. In actual engineering construction, there are many common hoisting methods. Among them, cable hoisting has become the preferred solution in many projects due to its high flexibility and strong adaptability.
[0003] However, in actual hoisting operations, existing hoisting equipment faces some pressing problems. Specifically, when hoisting precast components, a particular operating method is typically used: hooks with open designs are attached to plate hooks, and then tension is applied with ropes to slowly lift the entire component. During this process, once the component is in the air, as the height increases, external environmental factors begin to play a significant role, especially in outdoor working environments where there is often airflow, or "wind." When the wind blows towards the suspended precast component, due to aerodynamic principles, the precast component will experience significant wind force and produce noticeable impacts. The swaying is not a slight wobble, but a swaying that can cause the entire component to swing significantly. More importantly, the surfaces of the slab hooks and the components they work with are usually designed to be smooth for easy installation and disassembly. While this smooth surface improves operational efficiency to some extent, it also brings serious consequences. Under the continuous action of wind, combined with the swaying of the component itself, the slab hook is very likely to fall accidentally from the opening of the component. Once this happens, it will not only damage the precast wall panel, but may also cause a serious safety accident, posing a huge threat to the lives of construction workers, and will also affect the progress and quality of the entire project.
[0004] Therefore, this utility model provides a hoisting device for prefabricated engineering construction to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a hoisting equipment for prefabricated engineering construction, which solves the problem that the hoisting hook is very likely to fall accidentally from the opening of the component under the continuous action of wind and the swaying of the component itself.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A hoisting device for prefabricated engineering construction includes a hook and a hoisting plate. The top of the hoisting plate is fixed with a lug plate, and a pull rope is installed between the lug plate and the hoisting plate. The bottom of the suspended platform is equipped with a hook assembly, which includes multiple base plates installed at the bottom of the platform. The base plates are installed at the bottom of the platform with bolts and nuts. One side of the base plate has a slot and a receiving opening, and the receiving opening is connected to the slot. The inside of the base plate has two receiving grooves, and the receiving grooves are connected to the receiving opening. The two receiving grooves are symmetrical about the receiving opening. A connecting plate is provided between the two receiving grooves. Both sides of the connecting plate are slidably connected to the inner wall of the corresponding connecting plate. The connecting plate is used to support the platform hook.
[0007] Preferably, a clamping assembly is installed inside the base plate. The clamping assembly includes two side frames fixed to the inner wall of the receiving groove. The two side frames are symmetrical about the connecting plate. Each receiving groove has two corresponding side frames inside. An inner plate is provided between two adjacent side frames. Both sides of the inner plate are slidably connected to the inner wall of the corresponding side frame. A linkage plate is fixed to the side of the two inner plates facing the receiving opening. A pressing block is fixed to the bottom of the two linkage plates.
[0008] Preferably, each of the two inner plates has a side shaft fixed on the side away from the connecting plate, and each of the two connecting plates has two end plates fixed on one side. A pushing block is fixed on the side of the end plate facing the corresponding side shaft, which is used to push the inner plate to slide inside the side frame through the side shaft so that the pressing block presses and limits the plate hook.
[0009] Preferably, a pressing assembly is installed inside the base plate. The pressing assembly includes a first sliding plate fixed to one side of the connecting plate, a first sliding groove adapted to the first sliding plate and slidably connected to the inside of the first sliding groove on the base plate, a second sliding plate fixed to the top of the first sliding plate, a second sliding groove adapted to the second sliding plate and connected to the first sliding groove on the base plate, a pressure plate fixed to one side of the second sliding plate, a third sliding groove adapted to the pressure plate and connected to the second sliding groove on the base plate, and a pressure plate slidably connected to the inside of the third sliding groove.
[0010] Preferably, the extrusion block has an inclined surface, and the plate hook located inside the arc groove is initially positioned at the bottom end of the inclined surface of the extrusion block.
[0011] Preferably, a second return spring is fixed between one end of the inner plate located inside the side frame and the inner wall of the side frame to support the inner plate.
[0012] Preferably, the surface of the connecting plate is provided with an arc-shaped groove, and the arc-shaped groove is used for assembling the plate hook.
[0013] Preferably, a first return spring is fixed between the bottom of the connecting plate and the inner bottom wall of the receiving groove to support the connecting plate.
[0014] Preferably, a rubber pad is provided at the bottom of the pressure plate.
[0015] The beneficial effects of this utility model are as follows: 1. The hook and the plate are quickly connected by using a combination of ear plate and pull rope. The base plate design with bolt and nut fixation facilitates quick assembly and disassembly on site, shortening the construction preparation time. The bayonet-accommodation guide structure allows the plate hook to slide smoothly into the arc groove, reducing the difficulty of manual alignment and improving hooking efficiency.
[0016] 2. The first reset spring is set through the connecting plate, which can be dynamically compressed and buffered according to the weight of the precast component, so as to ensure stable bearing under different loads and avoid rigid impact damage to the component.
[0017] 3. By utilizing the gravity of the prefabricated components to move the connecting plate downwards, the clamping assembly is triggered, causing the extrusion block to automatically squeeze and limit the plate hook, thereby improving transportation stability.
[0018] 4. By pressing down the connecting plate with the pressing component, the pressure plate is pressed against the top of the linkage plate, which strengthens the limiting strength of the pressing block on the plate hook. Attached Figure Description

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0022] As attached Figures 1-6 As shown, a hoisting device for prefabricated engineering construction includes a hook 10 and a hoisting plate 11. A lug plate 12 is fixed to the top of the hoisting plate 11, and a pull rope 13 is installed between the lug plate 12 and the hoisting plate 11.
[0023] The bottom of the hanging plate 11 is equipped with a hook assembly 20 for assembling prefabricated components, thereby facilitating the transportation of prefabricated components.
[0024] The hook assembly 20 includes multiple base plates 21 installed at the bottom of the hanging plate 11. The multiple base plates 21 are all installed at the bottom of the base plate 21 by bolts and nuts. One side of the base plate 21 is provided with a snap 22 and a receiving opening 23, and the receiving opening 23 is connected to the snap 22. The inside of the base plate 21 is provided with two receiving grooves 24, and the receiving grooves 24 are connected to the receiving openings 23. The two receiving grooves 24 are symmetrical about the receiving openings 23. A connecting plate 25 is provided between the two receiving grooves 24.

A first return spring 27 is fixed between the bottom of the connecting plate 25 and the inner bottom wall of the receiving groove 24 to support the connecting plate 25, thereby facilitating the resetting of the connecting plate 25.
[0025] The base plate 21 is equipped with a clamping assembly 30, which is used to limit the position of the plate hook, thereby improving the stability of the prefabricated components during transportation.
[0026] The clamping assembly 30 includes two side frames 31 fixed to the inner wall of the receiving groove 24, and the two side frames 31 are symmetrical about the connecting plate 25. Each receiving groove 24 has two corresponding side frames 31 inside. An inner plate 32 is provided between two adjacent side frames 31, and both sides of the inner plate 32 are slidably connected to the inner wall of the corresponding side frame 31. A linkage plate 33 is fixed to the side of the two inner plates 32 facing the receiving opening 23. A pressing block 34 is fixed to the bottom of the two linkage plates 33. The pressing block 34 has an inclined surface, and the plate hook located inside the arc groove 26 is initially located at the bottom end of the inclined surface of the pressing block 34. Openings 35 are provided on both sides of the connecting plate 25 for the linkage plate 33 and the pressing block 34 to slide.
[0027] Two inner plates 32 are fixed with side shafts 36 on the side away from the connecting plate 25. Two end plates 37 are fixed on one side of each of the two connecting plates 25. Pushing blocks 38 are fixed on the side of the end plates 37 facing the corresponding side shafts 36. These blocks are used to push the inner plates 32 to slide inside the side frame 31 through the side shafts 36, thereby squeezing and limiting the plate hook through the squeezing blocks 34.
[0028] A second return spring 39 is fixed between one end of the inner plate 32 located inside the side frame 31 and the inner wall of the side frame 31 to support the inner plate 32, thereby facilitating the inner plate 32 to return to its original position.
[0029] The base plate 21 is equipped with a pressing component 40, which is used to press down the extrusion block 34, thereby increasing the extrusion strength of the extrusion block 34 on the plate hook.
[0030] The pressing assembly 40 includes a first sliding plate 41 fixed to one side of the connecting plate 25, a first sliding groove 42 adapted to the first sliding plate 41 on the bottom plate 21, and the first sliding plate 41 is slidably connected inside the first sliding groove 42.

[0031] In use, the workers will prefabricate the components and attach plate hooks. After the plate hooks are installed, the hook 10 is connected to the ear plate 12 on the hanging plate 11 via the pull rope 13 to secure it. Then, the slot 22 of the base plate 21 is aligned with the plate hook, and the base plate 21 is slid so that the plate hook slides through the slot 22 to the receiving opening 23 on the surface of the connecting plate 25. When the hook 10 moves the hanging plate 11 upward via the pull rope 13, the plate hook will move downward inside the receiving opening 23. Due to the weight of the prefabricated components, the prefabricated components move downward inside the receiving groove 24 via the plate hook, and the connecting plate 25 will compress the first return spring 27.
[0032] When the connecting plate 25 moves downward, the connecting plate 25 drives the pushing block 38 to move downward through the end plate 37, and the inclined surface of the pushing block 38 pushes the inner plate 32 to slide inside the side frame 31 through the side shaft 36. The inner plate 32 drives the linkage plate 33 to slide towards the connecting plate 25, and the plate hook slides from the bottom end to the top end of the inclined surface of the pressing block 34. At this time, the pressing block 34 can press and limit the plate hook. While the connecting plate 25 moves downward, it also drives the first sliding plate 41 to move downward inside the first slide groove 42. The first sliding plate 41 drives the second sliding plate 43 to move downward in the second slide groove 44, and the second sliding plate 43 drives the pressure plate 45 to move downward inside the third slide groove 46, so that the pressure plate 45 abuts against the top of the linkage plate 33, thereby strengthening the limiting strength of the pressing block 34 on the plate hook.
