The motor 1 adjusts the rotation speed and torque through the input shaft 4 and then drives the output gear 9 to rotate through the output shaft 7 after the speed is adjusted by the speed reducer 5, the output gear 9 provides rotating power for the gear ring 25, and the gear ring 25 drives the flywheel 24, the aligning roller bearing 20, the main shaft 19 and the roller 29 to synchronously rotate;
the rope arranging roller 16 gives axial force to the steel wire rope 23 so that the steel wire rope 23 is orderly wound on the surface of the roller 29 layer by layer, and the baffle 30 limits the boundary position of the steel wire rope 23 wound on the roller 29;
When the winch is required to be stopped, the friction plate of the electric hydraulic drum brake 3 holds the main shaft 19, so that the rotating speed of the output gear 9 is reduced, the rotating speed of the drum 29 and the main shaft 19 is reduced, the hydraulic oil pressure of the first hydraulic brake 32 and the second hydraulic brake 35 is reduced, the friction part of the brake clamps the surface of the brake disc 34 under the action of the belleville spring in the brake, and the generated friction force stops the rotation of the brake disc 34, so that the aim of stopping is fulfilled;
the wire rope 23 stops to be lowered or lifted, the ratchet 39 and the pawl 41 prevent the sudden failure of the brake after the roller 29 is stopped, the roller 29 is reversed, and the safety of the winch is ensured.
These and other changes can be made to the embodiments in light of the above detailed description, which includes examples of the best mode contemplated for carrying out the invention. The scope of the invention is defined by the appended claims, which are not limited by the present disclosure, but by the scope of the invention, and any equivalents or modifications thereof, which are within the scope of the invention as disclosed by those skilled in the art, are intended to be included in the scope of the invention.
