Disc-type brake winch for underground coal mining and hoisting method thereof

Abstract

The invention relates to the technical field of underground equipment, and discloses a disc-type brake winch for underground coal mining and a hoisting method thereof. The positions, above driven gears, of inner cavities of shells are movably sleeved with driving shafts, so that two sides above the inner cavities of the shells are directly sleeved with axles of a rotating shaft, and the two sidesof the rotating shaft are limited in the radial direction and can only rotate axially; and driving gears located on the two sides are simultaneously meshed with the driven gears, so that a transmission rod I and a transmission rod II can be linked without connection by a connecting shaft, and the problem of incapability of rotating due to the fact that too many traction lines on a driven shaft areblocked by the connecting shaft since the driving gears need to be connected by the connecting shaft is avoided. The maximum length of traction capable of being carried by the equipment is improved,and meanwhile, the transmission rod I and the transmission rod II are arranged on the driving shafts on the two sides, so that an operator can perform two-hand operation, the operation difficulty of original equipment is reduced, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of underground equipment, in particular to a disc-shaped braking drawworks for underground coal mining and a hoisting method thereof. Background technique [0002] Winch is a kind of equipment commonly used in various construction sites, also known as hoist, it can be divided into two types from the source of power, one is electric control type, and the other is manual type, which can be divided into single shaft from the structure Type and multi-shaft type, in which the disc brake winch is biaxially distributed, consisting of a driving shaft, a driven shaft, a gear set, a brake device and a housing bracket. This disc brake winch has the simplest structure and is easy to operate. Convenient, the effect of labor saving can be achieved through the principle of leverage. By manually rotating the driving shaft to drive the driven shaft to rotate, the rotation of the driven shaft can drive the sleeve sleeved on t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing disc brake winch proposed in the background technology, the present invention provides a disc brake winch for underground coal mining and its lifting method, which has a brake device that does not contact the gear And the advantage of not having too much friction, solves the problem that the contact mode between the brake device and the gear leads to the decrease of the service life of the gear and the problem of easy generation of static electricity
