Novel car-running protecting method of rail haulage in mine inclined shaft

Abstract

The invention relates to a novel car-running protecting method of rail haulage in a mine inclined shaft. A car-stopping railing, an opening and closing device of the car-stopping railing and a car-running state monitoring device are arranged; a traction winch of a mine car is provided with a monitoring device for operating state of the winch; the monitoring device for operating state of the winch and the car-running state monitoring device are connected with the opening and closing device of the car-stopping railing by a control circuit; under normal state, when the traction winch is not started, the monitoring device for operating state of the winch controls the opening and closing device of the car-stopping railing by a control circuit and the car-stopping railing is closed and is in a stopping state; when the traction winch is started, the monitoring device for operating state of the winch controls the opening and closing device of the car-stopping railing by a control circuit and the opening and closing device of the car-stopping railing controls the car-stopping railing to be opened; in the process of starting the car-running, the car-stopping railing is in opening state all the time; when the car running accident happens, the car-running state monitoring device detects the car running of the mine car, and a closing signal is sent to the opening and closing device by the control circuit; and the opening and closing device controls the car-stopping railing to fast close and stop the car-running. The method has flexible operation and low fault ratio.

Description

technical field [0001] The invention relates to a protection technology for sports car accidents during the process of lifting materials by a winch pulling a mine car along a track laid in an inclined shaft during rail transportation in an inclined shaft of a mine, in particular to a protection method for a new type of sports car for rail transportation in an inclined shaft of a mine. Background technique [0002] In the mine inclined shaft rail transportation, the mine car is pulled by the winch to lift the material along the track laid in the inclined shaft. In the process of lifting and lowering the material, due to various reasons, the lifted mine car may be out of traction control. The out-of-control mine car slid down the track rapidly, damaging the shaft facilities and posing a great threat to the life of the staff at the disembarkation yard. Therefore, sports car protection is a very important safety measure in mines. [0003] According to the working state of the ...

AI Technical Summary

Problems solved by technology

The disadvantage is: it is not easy to check, and it may be caused by electrical or mechanical failure, which may cause the barrier to not be closed quickly when running a sports car

The disadvantage is: the frequent opening of the car barrier, resulting in a high failure rate, and it is easy to cause mine car scraping or reverse pulling accidents, which is the key point that currently plagues coal mine transportation
