The hoisting frame 1 is provided with a hoisting component 2 in the horizontal groove 11, and the hoisting component 2 includes a rope column 24 and a main hoisting rope 241 that can drive the lifting and moving of building materials. One end of the main hoisting rope 241 is fixedly connected to the rope column 24, and a limit component 3 is provided at the end of the rope column 24.

The limiting component 3 also includes balls 312 rotatably connected to both sides of the support plate 31. Each ball 312 corresponds to and contacts the position of each slide groove 12. The limiting component 3 is also provided with a clamping component 4 for fixing the hoisted building materials. This design solves the problem in the prior art that the hoisted building materials will shake due to their own gravity and inertia during transportation, which in turn leads to the risk of collision or even falling off the hook.

[0024] See also Figure 2 The lifting assembly 2 also includes a first forward and reverse motor 21, which is fixedly mounted on the top of the lifting frame 1. The lifting assembly 2 also includes a worm 211. The top of the worm 211 is fixedly connected to the output end of the first forward and reverse motor 21. The worm 211 is rotatably connected to the transverse groove 11 through the first forward and reverse motor 21. The lifting assembly 2 also includes a support plate 23, which is fixedly connected to the bottom of the transverse groove 11. The lifting assembly 2 also includes a rotating column 22, which is rotatably connected to the support plate 23. The lifting assembly 2 also includes a worm gear 221, which is fixedly connected to the rotating column 22. The worm gear 221 is in contact with the worm 211 and rotates in meshing engagement. The lifting assembly 2 also includes a bearing 251, which is arranged in a slot on the side wall of the transverse groove 11. The outer ring of the bearing 251 is in contact with the transverse groove 1 1 side wall is fixedly connected, and the lifting assembly 2 also includes a rotating rod 25, one end of the rotating rod 25 is fixedly connected to the inner ring of the bearing 251. The bearing 251 can make the rope column 24 rotate more smoothly in the transverse groove 11. The other end of the rotating rod 25 is fixedly connected to the rope column 24. By starting the first forward and reverse motor 21, the worm 211 is driven to rotate, and then the worm wheel 221 located on the side of the worm 211 is synchronously meshed and rotated. At this time, the worm wheel 221 will drive the rope column 24 to rotate in the transverse groove 11 through the rotating column 22. Through this design, the main lifting rope 241 wrapped around the outside of the rope column 24 can drive the supporting plate 31 and the building materials on the top of the supporting plate 31 to achieve the lifting work.

The clamping assembly 4 also includes two groups of clamping plates 42, which are respectively threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 411. After the building material is placed on the top of the supporting plate 31, the second forward and reverse motor 41 can be started to drive the bidirectional threaded rod 411 to rotate, so that the clamping plates 42 threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 411 move synchronously toward each other until the building material is fixed. This design can prevent the building material from loosening and slipping during the lifting and transportation process with the supporting plate 31.

[0027] The working principle and use process of this utility model are as follows:

[0028] The staff first places the building material to be hoisted on top of the support plate 31, then starts the second forward and reverse motor 41 to drive the bidirectional threaded rod 411 to rotate, thereby causing the clamping plates 42 threadedly connected to the opposite threads on both sides of the bidirectional threaded rod 411 to move synchronously towards each other until the building material is fixed;

[0029] Then the first forward and reverse motor 21 can be started to drive the worm 211 to rotate, and the worm gear 221 can be used to complete the rotation of the rope column 24 in the horizontal groove 11. Through this design, the main lifting rope 241 wrapped around the outside of the rope column 24 can lift the limiting component 3 and the building materials on the top of the limiting component 3. At the same time, the worm 211 cooperates with the worm gear 221 to avoid falling back during the lifting and transportation process. At the same time, this design provides balls 312 corresponding to the position of the slide groove 12 on both sides of the support plate 31 to ensure that the hoisted building materials can only move vertically, thereby avoiding shaking during the lifting and transportation process.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
