Abstract

The invention discloses a mine safety device. A horizontal traffic lane is provided with a winch, a first support and a second support; one end of a steel wire rope is connected with the winch, and the other end of the steel wire rope is used for connecting a mine vehicle; the steel wire rope between the first support and the second support is connected with a tension force induction rope; the other end of the tension force induction rope is conneced with the rotary arm of a kick-up block arranged on an inclined shaft; a return spring is installed between the vehicle blocking plate and a vehicle blocking frame of the kick-up block; and when the steel wire rope is not connected with the mine vehicle, the steel wire rope is not stressed, the return spring on the vehicle blocking plate enables the vehicle blocking plate to be in a vehicle blocking state, only when the mine vehicle and the steel wire rope are connected well, the steel wire rope is stressed, and the vehicle blocking state can be released for the vehicle blocking plate. The device does not need manual operation and proffesional motive power, and the mine vehicle which is not connected with the steel wire rope can be prevented from sliding downward along the inclinded shaft to further hurt people below the inclined shaft, and the vehicle sliding problem which puzzles people in the mine well over the years is solved easily.

Description

Technical field [0001] The invention relates to a mine equipment, in particular to a mine safety device. Background technique [0002] Inclined shafts are the main traffic lanes for mining and transportation of mines. In some mines, there are many inclined shafts, and inclined shafts are built below them. There is no uniform standard for the slope of the inclined shaft, ranging from thirty degrees to forty degrees, and its depth varies from tens of meters to thousands of meters. Above each inclined shaft there is a large horizontal road with tracks and electric winches on which are placed mine carts. The mine carts are divided into heavy and empty mine carts. When the winch pulls the heavy mine cart up from the inclined shaft, the worker pulls out the latch, and the wire rope on the winch is separated from the mine cart; for empty mine carts, first group the empty mine carts, connect the adjacent mine carts, and plug in the latch , Hang the wire rope, check it carefully, then p...
