Preferably, the brake device includes a brake cylinder and a brake disc; the brake cylinder is fixed on the reel support of the reel assembly device through bolts, and the brake disc is fixed through keys and bolts On the reel shaft of the reel combination device; when the brake cylinder is working, the shaft of the brake cylinder protrudes to clamp and fix the brake disc, thereby realizing the fixation of the reel, When the shaft of the brake cylinder is retracted, the brake disc is released.

Preferably, the rope adjusting device includes a cylinder bracket, a cylinder, and an adjusting head; the cylinder bracket is fixed to the frame by bolts, the cylinder is fixed on the cylinder bracket by bolts, the adjustment head is connected to the frame The cylinder shaft of the cylinder is fixedly connected, the adjustment head has two rotatable pulleys, and the rope passes between the two pulleys; the expansion and contraction of the cylinder shaft can drive the adjustment head to move laterally, and then when the rope is retracted Realize the adjustment to the rope arrangement position.

The utility model also relates to a working method of a reducer built-in hoist, the specific steps are as follows: in the retracting stage, the motor rotates, the motor drives the shaft of the reel to rotate through the coupling, and the reel The combination device converts the reel shaft from a higher speed to a lower speed of the reel through the deceleration of the gear train, and the reel rotates to retract the rope, and the reel rotates at the same time The cylinder works, the cylinder shaft of the cylinder stretches and drives the adjustment head to move laterally, and the two pulleys of the adjustment head push the ropes to move to realize the adjustment of the arrangement position of the ropes on the reel. After the drum completes the retraction of the rope, the motor stops working, the brake cylinder works to clamp the brake disc, and then the reel is fixed; in the release stage, the brake cylinder works to make the brake disc The disc is released, the motor rotates in reverse, and the winch enters the release stage.
