When the circular piece 38 moves to one side of the friction anti-slip assembly 5, the reset spring 37 is compressed, and the cable transmission roller assembly 3 can be reset automatically after losing external force by the compression of the reset spring 37.

[0027] Further, in the embodiment, the friction anti-slip assembly 5 comprises a fixed seat 51, a first friction surface 52, a second friction surface 53 and a mounting ring 54, the mounting ring 54 is installed on the side wall of the fixed seat 51, the first friction surface 52 is constructed on the inner side wall of the fixed seat 51, the second friction surface 53 is constructed on the inner periphery of the fixed seat 51, and the mounting ring 54 and the fixed seat 51 are fixedly installed by a plurality of bolts.

When the traction device controls the release or winding of the cable, the cable is brought into contact with the rope cable, and the rope cable is rotated at a corresponding speed when the cable moves. When the cable is released, if the traction device fails and the speed is out of control, the cable will accelerate under its own gravity, causing the rope roller 32 to further increase in speed.

After the speed is reduced, the limiting spring 614 offsets the centrifugal force to move the penetrating rod 613 to the inside of the straight rod 611, so that the rope roller 32 restores the normal rotation speed. If the traction device is still in the out-of-control state, the rope roller 32 will constantly switch in the above state, and the speed of the rope roller 32 will always be kept within a safe range;

[0032] When the rope roller 32 needs to be stationary to stop the traction or release operation of the cable, the hydraulic push rod 35 is started. After the hydraulic push rod 35 is elongated, the rotating plate 36 is in contact with the end of the long rod 33, and then the long rod 33 is pushed to one side of the fixed seat 51 until the first friction disc is attached to the first friction surface 52 of the fixed seat 51. Thus, the rope roller 32 is limited and fixed. After the hydraulic push rod 35 is retracted, the return spring 37 is reset to the side of the hydraulic push rod 35, pushing away the round plate 38 so that the long rod 33 is reset.
