Damping type over discharge buffering device for mine hoisting system

Abstract

The invention relates to a damping type over discharge buffering device for a mine hoisting system. The damping type over discharge buffering device comprises a steel truss, a damping buffer and a buffering bracket, the steel truss is arranged on the mine wall of the bottom of a mine, one end of the damping buffer is connected with the steel truss, the other end of the damping buffer is connected with the buffering bracket, and a cage of the mine hoisting system falls on the buffering bracket during falling. By means of the damping type over discharge buffering device, a new over discharge prevention device is designed; the damping type over discharge buffering device is installed above over discharge prevention space at the mine bottom of the mine, the steel truss is arranged at the mine bottom, an over discharge prevention buffering device is hung on the steel truss, a damping groove is formed in a piston rod of a hydraulic cylinder, the depth size of the damping groove is changed along with stroke changes, the problem of insufficient over discharge prevention space of old mine transformation is solved, the over discharge prevention device can be additionally arranged in an old mine hoisting system, and security coefficients of mine production can be effectively improved; meanwhile, construction is simple, the construction period is short, the old-mine transformation halt period is short, and the old mine safety transformation problems are decreased as many as possible.

Description

Technical field: [0001] The invention belongs to the technical field of coal mine safety, and in particular relates to a damping type over-discharging buffer device for a mine hoisting system used in the reconstruction of an old mine. Background technique: [0002] With the development of my country's socialist market economy, the coal industry is facing a good opportunity for development, and coal enterprises are developing towards high output, low consumption, safe and intensive production. However, the safety production situation of coal enterprises is still relatively severe: on the one hand, the mining depth of coal mines is continuously increasing, and the production conditions are becoming more complicated, especially in old mines, where electromechanical equipment has been in debt for a long time, and some even operate with diseases; on the other hand, Some coal enterprises still blindly pursue economic benefits and neglect safety production. These have put a lot ...
