Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a laminated plate hoisting device, as Figure 1 and Figure 2 shown, which includes a pallet 1, a clamping mechanism, a threaded connecting rod 3 and a clamping assembly 4. A lifting ring 11 is fixedly connected to the upper end of the pallet 1, a plurality of main hook steel cables 12 are fixedly connected to the bottom surface of the pallet 1, a plurality of clamping mechanisms are arranged at the lower end of the pallet 1, and the plurality of clamping mechanisms are arranged in a linear arrangement. The clamping mechanism is composed of two sets of symmetrically arranged clamping units 2. The clamping unit 2 includes a horizontal plate 21, a grooved plate 22 and a support plate 23. A vertical plate 211 is fixedly connected to one side of the horizontal plate 21, and the vertical plate 211 is arranged vertically upward. A threaded connecting rod 3 is penetrated between the vertical plates 211 of the two sets of symmetrically arranged clamping units 2.

[0027] As Figure 2 and Figure 4As shown in the figure, on the other side of the horizontal plate 21, a plurality of groove plates 22 are fixedly connected. The groove plates 22 are arranged vertically downward. Adjacent groove plates 22 are paired in twos. A sliding groove 221 is formed through the side surface of the groove plate 22. A support plate 23 is arranged between two paired groove plates 22. One end of the support plate 23 is fixedly connected with a bolt rod 231. A through hole 232 is formed through the side surface of the support plate 23. The bolt rod 231 is slidably connected in the sliding groove 221. The support plate 23 is rotatably and slidably connected with the groove plate 22 through the bolt rod 231. A plurality of auxiliary hook cables 214 are arranged on the lower surface of the horizontal plate 21. The plurality of auxiliary hook cables 214 are linearly arranged along the length direction of the horizontal plate 21. A clamping assembly 4 is arranged at one end of the horizontal plate 21. The clamping assembly 4 connects and fixes the horizontal plate 21 and the support plate 23. Hook the plurality of auxiliary hook cables 214 on the lifting bars protruding from the surface of the concrete composite slab for hooking. Start the crane to lift the composite slab through the auxiliary hook cables 214, so that the bolt rod 231 on the support plate 23 slides downward along the sliding groove 221 on the groove plate 22. Rotate the support plate 23 to make the support plate 23 lie flat at the bottom of the composite slab. Tighten the fixing nut on the bolt rod 231 to fix the support plate 23. The support plate 23 can play a role in assisting the support of the bottom of the composite slab lifted by the auxiliary hook cables 214, reduce the tension borne by the auxiliary hook cables 214, and avoid the composite slab falling due to excessive force on the auxiliary hook cables 214 resulting in fracture.

[0028] As Figure 5 and Figure 6 shown, the clamping assembly 4 includes a long hook cylinder 41, a hook post 42 and a threaded connection cylinder 43. The long hook cylinder 41 is arranged at one end of the horizontal plate 21. The hook post 42 is arranged at the upper end of the long hook cylinder 41. Threads are provided on the outer circumferential sides of the long hook cylinder 41 and the hook post 42. The threaded connection cylinder 43 is sleeved at the connection of the long hook cylinder 41 and the hook post 42.

The free end of the hook post 42 is clamped to the upper surface of the cross plate 21. The interior of the threaded connection cylinder 43 is divided into two sections. The inner diameter of one section of the threaded connection cylinder 43 is the same as the diameter of the hook post 42 and is in threaded connection with the hook post 42. The inner diameter of the other section of the threaded connection cylinder 43 is the same as the diameter of the long hook cylinder 41 and is in threaded connection with the long hook cylinder 41. The long axis section of the long hook cylinder 41 is disposed through the through holes 232 of multiple support plates 23 to connect the multiple support plates 23. The hook post 42 is pulled to make the hook post 42 closely adhere to the upper surface of the cross plate 21. The threaded connection cylinder 43 is screwed downward so that the threaded connection cylinder 43 moves to the connection position between the long hook cylinder 41 and the hook post 42. The threaded connection cylinder 43 is threadedly connected to the outside of the long hook cylinder 41 and the hook post 42 to fix the hook post 42 on the long hook cylinder 41. The clamping assembly 4 can provide auxiliary support for keeping the support plate 23 in a flat state, preventing the fixing of the bolt rod 231 from loosening after the support plate 23 is stressed, resulting in the inclination of the support plate 23 and unable to provide good support for the bottom of the laminated plate.

A threaded sleeve 52 is threadedly connected between the adjacent two side threaded rods 51. According to the length of the laminated plate to be hoisted, different numbers of clamping mechanisms are selected and evenly linearly arranged in the length direction of the laminated plate to prevent the laminated plate from deflecting due to the offset of the center of gravity after being lifted. By controlling the distance that the side threaded rods 51 at both ends extend into the threaded sleeve 52, the distance between adjacent two groups of clamping mechanisms is adjusted.

[0030] Adopting the present utility model, as Figure 1 and Figure 2As shown, hook the lifting hook of the crane on the lifting ring 11, hook the main lifting hook cable 12 on the pulling ring 212, adjust the distance between the two sets of clamping units 2 arranged symmetrically so that the two sets of clamping units 2 clamp on both sides of the laminated slab, and then tighten the fixing nuts on the threaded connecting rod 3 to fix the positions of the two sets of clamping units 2. According to the length of the laminated slab to be lifted, select different numbers of clamping mechanisms and arrange them evenly in a linear manner in the length direction of the laminated slab. By controlling the distance that the two end side threaded rods 51 extend into the threaded sleeve 52, adjust the distance between adjacent two sets of clamping mechanisms. Hook multiple auxiliary lifting hook cables 214 on the lifting bars protruding from the surface of the concrete laminated slab for hooking. Start the crane and lift the laminated slab through the auxiliary lifting hook cables 214, so that the bolt rod 231 on the support plate 23 slides downward along the sliding groove 221 on the groove plate 22, and rotate the support plate 23 so that the support plate 23 is placed flat at the bottom of the laminated slab. Tighten the fixing nut on the bolt rod 231 to fix the support plate 23. The support plate 23 can play an auxiliary supporting role for the bottom of the laminated slab lifted by the auxiliary lifting hook cables 214. Pass the long axis section of the long hook cylinder 41 through the through holes 232 of multiple support plates 23 to connect the multiple support plates 23. Pull the hook post 42 so that the hook post 42 closely adheres to the upper surface of the cross plate 21, and screw down the threaded connection cylinder 43 downward so that the threaded connection cylinder 43 moves to the connection part of the long hook cylinder 41 and the hook post 42. The threaded connection cylinder 43 is threadedly connected to the outside of the long hook cylinder 41 and the hook post 42 to fix the hook post 42 on the long hook cylinder 41. The clamping assembly 4 can provide auxiliary support for the support plate 23 to maintain a flat state.
