Abstract

The invention discloses an overspeed protection rail car which comprises an overspeed detection device, a trigger system and an emergency stop system. The overspeed detection device comprises a speed taking device arranged on the vehicle body, the input end of the speed taking device is in transmission connection with running wheels at the bottom of the vehicle body through a chain, and when the speed of the running wheels exceeds the designed speed, a moving screw sleeve at the output end of the speed taking device moves forwards and presses a valve element of a brake valve set in the trigger system. A pressure spring release device in the trigger system works to drive a swing arm to swing downwards, a ferrule on the swing arm clamps a grab hook device, and the other end of the ferrule is wound on a buffer with damping, so that the rail car is stopped in real time. The steel wire rope on the buffer is used for braking the rail car in real time, active protection of the rail transport vehicle is achieved, and accidents caused after the speed of the rail transport vehicle is out of control are eliminated from the source.

Description

technical field [0001] The invention relates to the field of overspeed protection rail cars, in particular to an overspeed protection rail car. Background technique [0002] In mine production, rail transportation is an important transportation method for auxiliary transportation. In rail transportation, if the speed of the rail car is out of control, it will lead to serious accidents and secondary disasters, threatening the workers, and also affecting the production efficiency of coal mining. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an overspeed protection rail car, which can turn on the trigger system when the rail car exceeds the set movement speed, and use the wire rope on the buffer to immediately stop the rail car, so as to realize The active protection of rail transport vehicles eliminates the occurrence of accidents after the speed of rail transport vehicles is out o...
