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.

    本发明公开了一种超速保护轨道车,包括超速检测装置、触发系统以及急停系统;超速检测装置包括设在车体上的取速装置,取速装置的输入端与车体底部的行驶轮通过链条传动连接,当行驶轮速度超过设计速度时,取速装置输出端运动丝套前移并压紧触发系统内制动阀组的阀芯,触发系统内压簧释放装置工作带动摆臂向下摆动,摆臂上的套圈卡住抓钩装置,套圈另一端缠绕在带有阻尼的缓冲器上从而即时制停轨道车,本装置能够在轨道车超过设定运动速度时打开触发系统,利用缓冲器上的钢丝绳对轨道车进行即时制停,实现轨道运输车辆的主动防护,从源头上消除轨道运输车辆速度失控后的事故发生。
