Abstract

The invention discloses an active catcher which is characterized by comprising a frame, a primary brake, a secondary brake and a secondary braking starter; the bottom of the frame is respectively provided with a fixed pair wheel axle and a transmission pair wheel axle; the transmission pair wheel axle is fixedly provided with a first chain wheel; the first chain wheel is used for detecting a travelling speed of a series of cars, when the travelling speed of the series of cars is higher than a set value, the primary brake and the secondary brake are successively started, and safety braking is realized. The active catcher disclosed by the invention has simple structure, accurate speed measurement, stable braking and high safety and reliability.

Description

technical field [0001] The invention relates to safety equipment in mines and tunnels, more specifically to an anti-running device used in the hoisting of inclined shafts. Background technique [0002] At present, the regulations that must be followed when using string cars to lift in inclined shafts are: install sports car protection devices that can stop vehicles that break the rope and decouple in inclined shafts; A vehicle arrester that strays into a non-operating yard or section; install a vehicle arrester at the entrance of the upper flat yard that can control the vehicle from entering the decoupling point; The vehicle slides into the vehicle stop device of the inclined lane; a barrier bar is set not far below the slope point to prevent unconnected vehicles from continuing to go down the sports car. However, such protective devices for sports cars, stoppers and barriers are all limited to passive anti-sports cars in a certain section, and cannot block the vehicles in ...
