Braking device of steel wire traction rail passenger conveying car for mine

Abstract

The invention provides a braking device of a steel wire traction rail passenger conveying car for a mine for ensuring the safety of car conveying passengers and belongs to the technical field of equipment for the mine. The braking device solves the technical problem by adopting the technical scheme that the braking device comprises a brake shoe and an arc-shaped brake clamp, wherein one end of the arc-shaped brake clamp is hinged with the brake shoe, the other end of the arc-shaped brake clamp is hinged on a passenger conveying mine car, the brake shoe is in matched arrangement with wheels of the mine car, the middle part of the brake shoe is fixedly connected with a piston rod of a pushing air cylinder, a cylinder body of the pushing air cylinder is fixedly arranged at the bottom of the passenger conveying mine car, a spring capable of making the piston rod of the pushing air cylinder reset is arranged inside the pushing air cylinder, the pushing air cylinder is communicated with an air storage tank arranged on the passenger conveying mine car through an air guide pipe, and a control valve is arranged on the air guide pipe. The braking device can be widely applied to the braking of the mine car.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a safety device for a passenger car pulled by a steel wire. Background technique [0002] At present, the steel wire traction and hoisting rail mine car used in the inclined shaft of mining has a kind of passenger car specially used for carrying people. The operation of this car is the same as that of the mine car, and there is no braking device. When waiting for an accident, people and cars slide down at a high speed along the inclined shaft, which can easily cause a major accident of car crash. Contents of the invention [0003] The invention provides a braking device for a passenger car on a mine steel wire traction track, which overcomes the shortcomings of the prior art and provides a braking device for a passenger car on a mine steel wire traction track that ensures the safety of passengers. [0004] In order to solve the above-mentioned technical pr...
