In this embodiment, when the suspension mechanism 3 is in use, the adjusting rod 32 can be rotated to push the extrusion pad 321 to contact with the hanger plate 34, so as to increase the friction force with the hanger plate 34, so that the movable frame 31 will not slide on the surface of the hanger plate 34 at random during correction, but when the lifting mechanism 5 and the supporting component 4 are detached and separated, the position of the movable frame 31 on the surface of the hanger plate 34 needs to be controlled, so that the supporting plate 412 on one side of the supporting component 4 leaves the inserting groove 12, and before moving, the adjusting rod 32 needs to be rotated reversely, so that the extrusion pad 321 does not extrude the hanger plate 34 any more;
then, the moving frame 31 is controlled to start moving, the moving block 33 moves in the sliding groove 342, so that the limiting effect can be achieved when the moving frame 31 moves, in addition, the moving rods 331 on two sides of the moving block 33 also move in the moving groove 341, so that limiting guide can be achieved for the moving of the moving block 33, therefore, the moving frame 31 can be kept stable when the surface of the hanging plate 34 moves by utilizing the moving block 33 and the moving rods 331, and the hanging mechanism 3 is removed together with the supporting component 4 by utilizing the hanging tool after the supporting plate 412 leaves the inserting groove 12 along with the moving frame 31.
The application method and the working principle of the device are as follows: first, when the floor slab 1 is installed, the hanging hooks 343 on the surface of the hanging plate 34 can be tightly connected with the hanging hooks, when the floor slab 1 and the bottom plate 2 are moved to the top of the beam or the wall by the hanging hooks, and when the floor slab 1 and the bottom plate 2 are moved to the top of 50cm, the floor slab starts to slowly descend until the bottom plate 2 is contacted with the beam or the wall, and after the installation is completed, the lifting mechanism 5 and the supporting component 4 are in a suspended state.
