The invention discloses a hook-shaped rail holding device for preventing a subway train from derailing. The hook-shaped rail holding device comprises a train body mounting seat, a control box, a slideway panel and two hook claws, the control box is mounted on the vehicle body mounting seat; the slideway panel is connected with the vehicle body mounting seat, a plurality of sliding rails are arranged on the slideway panel, the upper ends of the claws are connected with the sliding rails, and the lower ends of the claws are free ends; when the control box collects that the acceleration of the vehicle body is abnormal, the air bag arranged in the control box explodes, and the hook claw moves towards the rail along the sliding rail under the action of the gravity of the hook claw and the impact force of the air bag. When the distance between the vehicle body and the rail surface exceeds a set distance, the lower end of the claw falls below the rail, and when the vertical lifting amount of the vehicle body exceeds a set value, the lower end of the claw is matched with the rail to generate resistance force for preventing the vehicle body from continuing to move upwards, so that the vertical displacement of the vehicle body is limited, and the abnormal movement posture of the vehicle body in the collision process is effectively limited.
本发明公开了一种防止地铁列车脱轨的钩状抱轨装置,包括车体安装座、控制盒、滑道面板、两个钩爪;控制盒安装在车体安装座上;滑道面板与车体安装座连接,滑道面板上设有多个滑轨,钩爪的上端与滑轨连接,钩爪的下端为自由端;当控制盒采集到车体的加速度异常时,控制盒内设置的气囊爆炸,钩爪在自身重力与气囊的冲击力作用下沿滑轨朝向轨道的方向运动;当车体与轨面之间的距离超过设定距离时,钩爪的下端落入轨道的下方,当车体的垂向抬升量超过设定值时,钩爪的下端与轨道配合,产生防止车体继续向上的阻抗力,限制车体的垂向位移,有效限制车体的碰撞过程中异常运动姿态。
