Double-winding-drum transmission device of motor-driven winch

Abstract

The invention relates to a winch, in particular to a double-winding-drum transmission device of a motor-driven winch. The transmission device comprises a reduction gearbox and a double-winding-drum wire reel. The reduction gearbox comprises a shell; a gear shifting shaft, a first input shaft, an intermediate transmission shaft, an output shaft and a brake shaft are installed in the shell through first bearings, the gear shifting shaft, the first input shaft, the intermediate transmission shaft and the output shaft are parallel with one another, and the brake shaft is fixed in the shell; a speed changing power output triple gear and a reversing dual gear are installed on the first input shaft, and a speed changing sliding triple gear and a reversing sliding dual gear are connected to the gear shifting shaft through splines; a reversing idle gear is installed between the reversing dual gear and the reversing sliding dual gear through a rotating shaft. According to the transmission device, the reversing sliding dual gear is adopted, and the transmission ratio of the reversing sliding dual gear to a gear on the left side of the reversing dual gear is equal to that of the reversing sliding dual gear to a gear on the right side of the reversing dual gear to the idle gear, so that the speed of a forward gear of the winch is equal to that of a reverse gear of the winch, and operation is facilitated for operators.

Description

technical field [0001] The invention relates to a winch mill, in particular to a double drum motorized winch mill transmission device. Background technique [0002] At present, during the construction and maintenance of power transmission lines, it is often necessary to erect poles and towers, spread wires, adjust ropes, stay wires and block blocks, and use winches as traction tools. In the prior art, commonly used winches are mainly divided into hand-operated winches and motorized winches. Hand-operated winches are devices that pull cables or tighten wires by manually rotating the rocker to drive the winding shaft to rotate. . The motorized winch is a device that uses a diesel engine to drive the winding shaft to rotate to pull the cable or tighten the wire. [0003] The hand-operated winch rotates the rocker through the operator's arm force, and then drives the winding shaft to work. Due to the limited strength of the operator's arm, the traction force produced by the h...

AI Technical Summary

Problems solved by technology

Due to the limited strength of the operator's arm, the traction generated by the hand winch is also relatively small, and the traction cannot be completed with the hand winch

[0004] There are obvious defects in the structure of the existing motorized winch mill: 1. The structure is unreasonable, and the phenomenon of running and grinding is prone to occur; 2. The single drum is used, the traction speed is slow, and the traction rope is always in a state of mutual extrusion; 3. The speed of forward and reverse rotation is not The same, it is easy to bring the prediction error of hoisting to the operator when operating; 4. The speed adjustment range is narrow
