[0025] Working principle: When working, first, under the action of the mounting bolts 2, the top plate 1 is fixed and installed, and then the rotating disk 30 is pulled downward, the rotating disk 30 drives the rotating support rod 28 to move downward, the rotating support rod 28 drives the movable block 24 to move downward, the movable block 24 drives the sliding block 25 to slide inside the sliding groove, and at the same time, the movable block 24 moves downward to squeeze the spring 29, so that the spring 29 undergoes elastic deformation, and at the same time, the rotating disk 30 drives the positioning column 31 to move downward, the positioning column 31 moves downward and disengages from the positioning hole 32, and the top of the rotating disk 30 is released. The rotating disk 30 is then rotated to drive the rotating support rod 28 to rotate, the rotating support rod 28 drives the movable block 24 to rotate, the movable block 24 drives the rotating sleeve 22 to rotate through the interaction of the sliding block 25 and the sliding groove 26, the rotating sleeve 22 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the second bevel gear 14 to rotate, the second bevel gear 14 drives the bidirectional screw 8 to rotate, the bidirectional screw 8 drives the threaded movable sleeve 9 to move, the threaded movable sleeve 9 drives the first positioning slider 16 to rotate. The first positioning slot 17 slides inside to ensure that the threaded sleeve 9 achieves better stability when moving. At the same time, the threaded sleeve 9 drives the first connecting shaft 10 to move, and the first connecting shaft 10 drives the connecting rod 11 to move. The connecting rod 11 applies a thrust to the top plate 1 through the second connecting shaft 12. Then, under the action of the force, the positioning sleeve 18 slides downward on the outside of the positioning support rod 19, and the positioning sleeve 18 pushes the support plate 3 to move downward through the positioning frame 7, and the support plate 3 drives the pipe clamp 4 to move downward. After the pipe clamp 4 reaches the required height, the rotation of the rotating disk 30 is stopped, and then the rotating disk 30 is released. Under the rebound force of the spring 29, the movable block 24 is pushed to move up and reset. The movable block 24 drives the rotating disk 30 to move up and reset through the rotating support rod 28. The rotating disk 30 drives the positioning column 31 to be inserted into the corresponding positioning hole 32, and the rotating disk 30 is repositioned. In this way, the seismic bracket can be used to hoist the fire pipe. It is convenient to adjust the hoisting height according to needs, reducing limitations, so as to achieve better practicality.
