The invention discloses a rail clamping constraint type active anti-derailing device for a high-speed railway train. The active anti-derailing device comprises a fixed seat, a rail pressing wheel frame, a clamping arm, a rail pressing wheel and a rail clamping wheel, a cross-shaped groove is formed in the fixing base, rail pressing wheel frames are elastically installed at the two ends of a transverse groove of the cross-shaped groove respectively, a pair of clamping arms which are located in a longitudinal groove of the cross-shaped groove and can be opened and closed is hinged between the two rail pressing wheel frames, rail pressing wheels are installed at the bottoms of the rail pressing wheel frames, and rail clamping wheels are installed at the tail ends of the clamping arms. The fixing seat is fixed on a bottom plate of a side beam of a train bogie, and the device does not affect normal running of a train. When a train tends to derail, on the premise that the rail pressing wheels press the top face of the rail, the two rail clamping wheels clamp and buckle the two sides of the top of the rail at the same time, all-directional rapid and safe braking is achieved, and it is guaranteed that the train stably stops on the rail. When the train runs back to normal, the wheel bogie resets upwards, the rail pressing wheels are separated from the top face of the rail, the rail pressing wheel frame restores downwards to the initial state, the clamping arms are opened to the initial state, and normal running of the train is not affected.

    本发明公开了一种夹轨约束型高速铁路列车主动防脱轨装置,包括固定座、压轨轮架、夹持臂、压轨轮和夹轨轮;固定座上设置有十字形槽,十字形槽的横向槽两端分别弹性安装有压轨轮架,两压轨轮架之间铰接一对位于十字形槽纵向槽中可开合的夹持臂,压轨轮安装于压轨轮架的底部,夹持臂的末端安装夹轨轮。固定座固定于列车转向架侧梁底板上,本装置不影响列车正常行驶。有脱轨倾向时,压轨轮压住轨道顶面的前提下,两夹轨轮同时夹紧并扣住轨道顶部两侧,实现全方位快速安全的制动,保证列车稳稳的停在轨道上。当列车行驶恢复正常后,车轮转向架向上复位,压轨轮脱离轨道顶面,压轨轮架向下恢复至初始状态,夹持臂打开至初始状态,不影响列车正常行驶。
