Description

Mine lifting machine safety arrangement Technical Field The utility model relates to the technical field of mining machinery safety, in particular to a safety protection device of a mine hoist. Background The mine hoisting machine is used as core equipment in the mine exploitation process, bears the vertical transportation task of personnel and materials, the operation safety and reliability of the mine hoisting machine are directly related to the production efficiency and economic benefit of a mine and the life safety of miners, and along with the continuous increase of the mine exploitation depth and the increasing expansion of the exploitation scale, the mine hoisting machine faces more complicated working conditions and higher safety risks, and higher requirements are put forward on the performance and the function of the safety protection device. Because part of the steel wire rope is wound on the left side and the right side of the roller shaft when the steel wire rope is wound on the winding roller shaft, the steel wire rope is always in a state of being led downwards in an inclined way when the steel wire rope is loosened, the braking equipment is generally arranged on the steel wire roller shaft, in this case, the braking of the steel wire rope is deviated, and particularly, the braking effect and the protection effect are poor for the steel wire rope positioned at the left end or the right end part; The prior patent (bulletin number: CN 221565470U) discloses a safety protection device of a mine hoist, a plurality of guide rollers can guide a steel wire rope, so that the steel wire rope is vertically and downwards guided, a mounting frame is controlled to move towards the guide rollers through a safety system, the steel wire rope can be tightly pressed between the guide rollers and a pressing piece through the pressing piece, the safety protection performance is improved, the guide rollers and the pressing piece can be kept a safe distance under a normal state by a length adjusting frame, the pressing piece can be pulled to move towards the guide rollers by the length adjusting frame under the control or power failure condition of a safety system, the steel wire rope on the guide rollers is tightly pressed, and the safety is higher.
