Problems solved by technology

[0002] The traditional mine damper chain is realized by the two-way connection control of the chain rope. In the past, due to the elastic deformation of the steel wire rope and the lack of design of the coal mine damper chain device, the coal mine damper "simultaneously activated" often occurred, resulting in a temporary wind flow. "Short circuit" causes the ventilation system to be disordered and affects mine safety production

Abstract

A balance weight air door interlocking control device comprises two brackets, a casing pipe is arranged in each bracket and connected with the bracket, a balance weight is arranged in each casing pipe, a digging rope is fixedly connected with the upper end of each balance weight, a limiting buckle is fixedly connected with the upper portion of each digging rope, and a balance component is arranged between the casing pipes.

Description

technical field [0001] The invention relates to a mine ventilation special device, in particular to a counterweight damper locking control device. Background technique [0002] The traditional mine damper chain is realized by the two-way connection control of the chain rope. In the past, due to the elastic deformation of the steel wire rope and the lack of design of the coal mine damper chain device, the coal mine damper "simultaneously activated" often occurred, resulting in temporary wind flow. "Short circuit" causes the ventilation system to be disordered and affects the safe production of the mine. Contents of the invention [0003] The purpose of the present invention is to provide a counterweight damper locking control device that can realize the reliable locking of the damper in the coal mine, avoid the short circuit of the wind flow, ensure the stability of the mine ventilation system, and effectively and fundamentally avoid the occurrence of major ventilation acci...
