[0012] In this technical solution, when it is necessary to adjust the height of the rope winding cylinder, through the provided driving component, the sliding block can be driven to slide upward, and the sliding block drives the rope winding cylinder to move upward, achieving the function of adjusting the height of the rope winding cylinder;

[0013] When it is necessary to disassemble the rope winding cylinder, through the provided power component, the disc can be driven to rotate. The disc drives a plurality of movable columns to slide and rotate respectively through a plurality of arc-shaped grooves. A plurality of movable columns drive a plurality of limiting strips to slide and move away from each other respectively. When one ends of a plurality of the limiting strips all break away from the rectangular plate, the personnel can pull the rope winding cylinder and drive the rectangular plate to break away from the power cavity, and the rope winding cylinder can be disassembled, and the operation is simple without using tools;

[0014] When it is necessary to install the rope winding cylinder, first insert the rectangular plate into the power cavity. Through the provided power component, the disc can be driven to rotate in the reverse direction. The disc drives a plurality of movable columns to slide and rotate respectively through a plurality of arc-shaped grooves.
