The nylon drum 21 is driven by the motor reducer 26, and its speed is adjustable. The winch frame 27 is spliced with aluminum alloy profiles, and a universal wheel is installed at the bottom for convenient and flexible movement.

The tension compensation mechanism 12 is mainly composed of three sets of spring-loaded movable pulleys and is equipped with a proximity switch. When the tension of the optical fiber reaches a certain value, the proximity switch senses a signal, and at this moment the motor driving the nylon reel 21 is powered off and the optical fiber is no longer retracted;

The automatic cable arrangement mechanism 13 mainly adopts the form of a reciprocating screw, and uses a small sprocket 46 on the drum shaft 25 to drive a large sprocket 44 on the reciprocating screw 49 through a chain 45 to achieve reciprocating automatic cable arrangement;

The automatic pay-off mechanism 14 mainly adopts the method of clamping the optical fiber with upper and lower belts, and uses a servo motor to actively pay out the optical fiber. When collecting the optical fiber, the servo motor is in a power-off state, and the damping of the automatic rope-laying machine body is used to provide the tension required for optical fiber recovery to prevent the optical fiber on the reel from becoming tangled.

When releasing the optical fiber, the first step is to open the motor brake of the motor reducer 26 of the winch mechanism 11 to ensure that the brake is in the energized state, the second step is to start the servo motor 55 of the automatic pay-off mechanism 14, and after the optical fiber is tensioned, start the motor of the winch mechanism 11 (to let the motor rotate), and the third step is to release the optical fiber under the joint action of the servo motor 55 and the motor of the winch mechanism 11;

When retracting the optical fiber, the first step is to cut off the power of the motor of the hoisting mechanism 11, the second step is to cut off the power of the servo motor 55, and the third step is to start the motor of the hoisting mechanism 11 to rotate in the reverse direction to retract the optical fiber.
