[0002] In construction and engineering projects, hoisting, as an important construction method, plays a crucial role. A reasonable hoisting plan can not only improve work efficiency but also ensure safety. However, special hoisting devices are still needed when hoisting some special building materials.

[0003] The utility model with the authorized publication number of CN220766285U discloses a plate hoisting device for building construction, which includes a support beam, with two lifting rings and a driving motor arranged at the top. The output shaft of the driving motor penetrates through the support beam and extends to the lower part of the support beam and is provided with a driving bevel gear. A guide groove is arranged on the lower surface of the support beam, and a bidirectional lead screw is arranged below the support beam, with both ends rotatably connected to the support beam respectively. A driven bevel gear meshing with the driving bevel gear is arranged at the middle position of the bidirectional lead screw. Two sliders are arranged on the bidirectional lead screw, and the top ends of the sliders are matched with the guide groove. A hook assembly is connected to the lower part of each slider, and a telescopic pressing member is fixed on the support beam for pressing the plates on the two hook assemblies.

[0004] Although the above technical solution improves the stability of the plate hoisting process through two hook assemblies and a telescopic pressing member, preventing the risk of the plate shifting or falling during hoisting, the above technical solution can only fix the four surfaces of the plate, and there is no fixing method for the other two surfaces. When the plate is hoisted to a high altitude, strong winds may blow the plate up from the two unfixed surfaces, and there may be a certain risk. Therefore, those skilled in the art provide a plate hoisting device for building construction to solve the problems raised in the above background technique. Utility Model Content

[0005] In view of this, it is necessary to provide a plate hoisting device for building construction to solve the problem that the plate is easily blown by strong winds when hoisted at a high altitude, posing a certain safety hazard.

[0006] According to one aspect of the present utility model, there is provided a plate hoisting device for building construction, including a wooden board. Below the wooden board, there are eight hoisting frames. On one side of each group of hoisting frames that are close to each other, two supporting rods are fixedly connected.

On the inner wall of each group of bearings, a threaded rod is fixedly connected. On the outer surface of each threaded rod, a lifting plate is threadedly connected. The bottom surface of each lifting plate is in contact with the upper surface of the wooden board. On the upper surface of each threaded rod, a manual rotating wheel is fixedly connected.

[0007] According to some embodiments, on the outside of each hoisting frame, a lifting ring is provided. On the outer surface of each lifting ring, it is rotatably connected to the inner wall of the hoisting frame.

[0008] According to some embodiments, on the outer surface of each hoisting frame, an anti-slip pad is fixedly connected. On the outer surface of each anti-slip pad, it is in contact with the outer surface of the wooden board.

[0012] According to some embodiments, on the outside of each elliptical ring, two chains are provided. On the outer surface of each group of chains, it is in contact with the outer surface of the elliptical ring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Detailed implementation manners

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Please refer to Figures 1 to 4 , the present invention provides a plate hoisting device for building construction, including a wooden board 1. There are eight hoisting frames 2 arranged below the wooden board 1. Two support rods 3 are fixedly connected to the side surfaces of each group of hoisting frames 2 close to each other. Fixing frames 4 are fixedly connected to the outer surfaces of each group of support rods 3. Two bearings 5 are fixedly connected to the inner walls of each fixing frame 4. Threaded rods 6 are fixedly connected to the inner walls of each group of bearings 5. Lifting plates 7 are threadedly connected to the outer surfaces of each threaded rod 6. The bottom surfaces of each lifting plate 7 are in contact with the upper surface of the wooden board 1. Manual rotating wheels 8 are fixedly connected to the upper surfaces of each threaded rod 6.

[0023] First, the lifting frame 2 can support the bottom surface and the four surrounding surfaces of the wooden board 1. Then, the height of the lifting plate 7 can be adjusted according to the thickness of the lifted wooden board 1. By turning the manual wheel 8, the threaded rod 6 can be driven to rotate. The rotation of the threaded rod 6 can achieve the effect of lifting or lowering the lifting plate 7, and further can achieve the purpose of compacting the lifted wooden board 1.

[0024] Furthermore, a lifting ring 9 is provided on the outer side of each lifting frame 2. The outer surface of each lifting ring 9 is rotatably connected to the inner wall of the lifting frame 2. The lifting ring 9 rotates inside the lifting frame 2, which is convenient for the lifting ring 9 to automatically adjust the evenness of the force when it is lifted.

[0025] Furthermore, an anti-slip pad 10 is fixedly connected to the outer surface of each lifting frame 2. The outer surface of each anti-slip pad 10 is in contact with the outer surface of the wooden board 1. The anti-slip pad 10 plays a protective role to avoid scratching the lifted board.

[0026] Furthermore, a hook 11 is provided above the wooden board 1. A suspension rod 12 is fixedly connected to the outer surface of the hook 11. The hook 11 is used to connect the hook of the tower crane, and the suspension rod 12 is convenient for adjusting the overall angle of the lifting frame 2.

[0027] Furthermore, a swivel hook 13 is provided on the outer side of the suspension rod 12. The inner wall of the swivel hook 13 is rotatably connected to the outer surface of the suspension rod 12. The cooperation between the swivel hook 13 and the suspension rod 12 can facilitate the workers to adjust the placement angle of the wooden board 1 when it is lifted to the destination.

[0028] Furthermore, four elliptical rings 14 are provided inside the swivel hook 13. The outer surface of each elliptical ring 14 is in contact with the outer surface of the swivel hook 13. The elliptical rings 14 play a role in dispersing the directions of the four groups of lifting frames 2 and preventing the two groups of lifting frames 2 from getting entangled with each other.

[0029] Furthermore, two chains 15 are provided on the outer side of each elliptical ring 14. The outer surface of each group of chains 15 is in contact with the outer surface of the elliptical ring 14. The chains 15 play a connecting role, and controlling the length of the chains 15 can determine the size of the lifted wooden board 1.

[0030] Working principle: When in use, first place the whole lifting mechanism around the wooden board 1, and cooperate with the tower crane at the construction site to lift the device to an appropriate height. The staff place the lifting frame 2 under the wooden board 1, and the height of the lifting plate 7 can be adjusted according to the thickness of the lifted wooden board 1. At this time, the four groups of lifting frames 2 can firmly support the bottom surface and the four surrounding surfaces of the wooden board 1;

[0031] Then manually rotate the manual rotating wheel 8. Utilizing the fixed connection between the manual rotating wheel 8 and the threaded rod 6, when the manual rotating wheel 8 rotates, it can drive the threaded rod 6 to rotate. Utilizing the threaded connection between the threaded rod 6 and the lifting plate 7, when the threaded rod 6 rotates, it can control the lifting or lowering effect of the lifting plate 7. Furthermore, the purpose of compacting the hoisted wooden board 1 can be achieved by means of the lifting plate 7, avoiding the problem that the wooden board 1 is blown up by strong winds when it is lifted in the air.
