The invention relates to a train emergency brake trigger device. The train emergency brake trigger device comprises a shell, a swing rod, a transmission mechanism and a trigger mechanism; the transmission mechanism comprises a swing rod shaft, a swing rod bearing, a cam, an axial limiting assembly, a limiting column, a torsional spring and a torsional spring seat; the trigger mechanism comprises amounting seat, a roller, a transmission bracket, a contact, a contact bolt and a support block; when the swing rod is impacted by a trackside check block arranged beside a train track to rotate, theswing rod drives the swing rod shaft, the torsion spring seat and the cam to rotate; and when the cam rotates to a certain angle, the roller slides out of the groove of the cam, so that the second endof the transmission bracket is lifted, the first end of the transmission bracket is far away from the first end of the mounting seat, so that the contact bolt is disconnected from the contact, and anemergency braking signal is output. According to the train emergency brake trigger device, on the premise that the trackside check block is arranged, manual monitoring and control are not needed, andit can be ensured that emergency braking is triggered when the train runs to the preset position; and delayed emergency braking of the train due to received wrong instruction or misoperation of a driver is prevented.

    本发明涉及一种列车紧急制动触发装置,包括:壳体、摆杆、传动机构和触发机构;传动机构包括摆杆轴、摆杆轴承、凸轮、轴向限位组件、限位柱、扭簧和扭簧座;触发机构包括安装座、滚轮、传动支架、触头、触头螺栓、支撑块;当摆杆受到设置在列车轨道旁的轨旁挡块的撞击而转动时,带动摆杆轴、扭簧座和凸轮转动;凸轮转动至一定角度时,滚轮从凸轮的凹槽滑出,使得传动支架的第二端抬起,传动支架的第一端远离安装座的第一端,使触头螺栓与触头断开接触,输出紧急制动信号。本发明在设置好轨旁挡块的前提下,无需人为监测和控制,可以确保列车在行驶到预设位置时触发紧急制动。防止因接收错误指令或者驾驶员操作失误导致列车紧急制动不及时。
