[0036] In the present embodiment, a rope brake assembly is also included, including a friction hoop 16, a brake pad 17 and a telescopic member 18.

Furthermore, the spring is connected to the frame 1 by a connecting rod to limit the position of the spring, so as to avoid the overall shaking of the clamping plate 20 and improve the stability of the device.

[0038] Working principle: During the rope threading operation, initially, the rope guide clutch assembly 10 and the large rope clutch assembly 11 are both in a separated state, and the rope guide brake assembly and the large rope brake assembly are both in a free state with the brakes opened; the power member 2 is started, the output end of the power member 2 drives the small gear 7 to rotate, the small gear 7 engages and drives the large gear 8 to rotate, the central axis of the large gear rotates, the rope guide clutch assembly 10 is closed, the rope guide drum 4 starts to rotate, the rope guide on the rope guide drum 4 passes through the pulley block to be threaded and then is connected to the large rope to pull the large rope through the pulley block, thereby realizing the large rope threading operation; at this time, since the large rope clutch assembly 11 is in a separated state, the large rope drum 6 is in the rope guide The rope reel 4 is freely rotated under the action of the pulling force. During the operation, when the operation needs to be interrupted, the rope clutch assembly 10 is separated, so that there is no power transmission on the rope reel 4 at this time, and then the telescopic member 18 is extended to make the brake pad 17 contact with the friction hoop 16, and the rotation of the rope reel 4 is slowed down by the friction force. Due to the large weight and inertia of the large rope reel 6, it is also necessary to brake the large rope reel 6, clamp the clamping plate 20 in the direction of the brake disc 19 and contact the brake disc 19, and slow down the rotation of the large rope main shaft 5 through the friction between the friction pad and the brake disc 19, so that the large rope reel 6 stops rotating through the lever assembly to avoid the phenomenon of large rope winding disorder;

[0039] During the rope collection operation, initially, the rope-leading clutch assembly 10 and the large rope clutch assembly 11 are both in a separated state, and the rope-leading brake assembly and the large rope brake assembly are both in a free state with the brakes turned on; the power member 2 is started, and the output end of the power member 2 drives the small gear 7 to rotate, and the small gear 7 drives the large gear 8 to mesh and rotate, and the central axis of the large gear rotates, and the large rope clutch assembly 11 is closed, and the arm 10 connected through the large rope main shaft 5 rotates as a whole, so that the pin 11 on the arm 10 rotates to drive the large rope drum 6 to rotate, so that the large rope drum 6 can be rotated to collect the rope. When the rope is collected and braking is required, the large rope clutch assembly 11 is separated, and the clamping plate 20 is clamped in the direction of the brake disc 19 and contacts the brake disc 19, and the rotation of the large rope main shaft 5 is slowed down by the friction between the friction plate and the brake disc 19, so that the rotation of the large rope drum 6 is stopped through the lever assembly.
