Reverse automatic anti-collision arrester for coal mine inclined drift runway vehicle protective device

Abstract

The invention relates to a reverse automatic anti-collision arrester for a coal mine inclined drift runway vehicle protective device, belonging to the technical field of safety devices for mines. The arrester comprises an arrester installation frame, an arrester, an arrester retraction mechanism and an arrester electric control system, wherein the arrester electric control system is used for detecting first and second lifting or descending points of the arrester, opening and closing of the arrester retraction mechanism and running and stopping of a mine car; the arrester and the arrester retraction mechanism are installed on the arrester installation frame; the opening direction of the arrester is the same with the collision direction of the mine car on the arrester during reverse ascending; and the arrester retraction mechanism is provided with an upper limit sensor and a lower limit sensor which are used for detecting the opening, closing or partly opening state of the arrester. The reverse automatic anti-collision arrester has the advantage that: as the arrester on the arrester installation frame is designed into the condition that the opening direction of the arrester is the same with the collision direction of the mine car on the arrester during reverse ascending, an accident that the mine car collides the arrester during the reverse ascending process is effectively prevented.

Description

technical field [0001] The invention relates to a reverse automatic anti-collision barrier for a sports car protection device in an inclined lane in a coal mine, and belongs to the technical field of mine safety facilities. Background technique [0002] When the car barrier plays a role to block the sports car and prevent the mine car from rolling down to the bottom of the well, in order to reduce the damage of the car barrier and the mine car due to collision, a buffer energy absorber is arranged above the inclined track where the car barrier is located, and used The steel wire rope connects the buffer energy absorber with the bumper, which can realize buffering and interception when the mine car and the bumper collide. [0003] However, because the original intention of the design of the car barrier is to prevent the mine car from getting out of control and slipping to the bottom of the well during the downward process, it does not consider the situation that the mine car ...
