Abstract

The present invention relates to mine runaway preventer, and is especially a kind of normally closed slope mine car runaway preventer interlinked with winch. The mine car runaway preventer includes two mine car barriers, each of which comprises a energy absorber fixed on the ground, mine car arresting nets on two sides of the energy absorber and one lifting motor to elevate the arresting nets, set in certain interval inside the inclined shaft; one mine car depth indicator and one control circuit to control the operation of the mine car barriers. The present invention has reasonable structure, capacity of interlinking with different types of winch and function of preventing mine car runaway effectively, and is suitable for use in inclined lifting transportation tunnel of inclination below 30 deg.

Description

technical field [0001] The invention relates to a mine anti-car device, in particular to a normally closed anti-car device for an inclined shaft linked with a winch. Background technique [0002] According to the requirements of Article 370 of the "Coal Mine Safety Regulations", the inclined shaft (inclined lane) of the coal mine must be installed with a normally closed anti-running device. Set up a set of car blocking protection devices at a distance. When the mine car passes by, the device is opened to let the mine car pass by. After the mine car passes, the device is in the car blocking state. At present, most of the anti-car devices use mechanical control methods that cannot be linked with the operation of the winch to realize opening and closing, but the mechanical control is easy to fail and cause accidents; The condition of the anti-sports car device, but due to human factors or the situation that the car blocking device is in an open state when a sports car accident...
