The invention discloses an active anti-derailment method for a high-speed railway train based on an electromagnetic driving clasping rail, which is characterized in that a clasping rail device is detachably connected to the lower side of a bogie of the high-speed railway train, the clasping rail device can be automatically opened and closed, and when the train runs normally, the clasping rail device is positioned on the periphery of the rail and does not influence the normal running of the train; when a train tends to derail under the action of sudden earthquakes, the rail buckling assembly of the rail holding and buckling device firstly shrinks the gap between the rail and the rail to be in a rail holding state, and then the rail buckling execution assembly of the rail holding and buckling assembly is driven by electromagnetic force to quickly pop up to buckle the two side faces of a rail flange and the two side faces of a rail web at the same time. When an earthquake occurs, the rail holding and buckling assembly of the rail holding and buckling device is powered on, the rail buckling execution assembly is driven by strong electromagnetic force to buckle the two side faces of the rail flange and the two side faces of the rail web at the same time, a train is locked on the rail to avoid overturning, lateral derailing and upward rail jumping of the train are limited, and the safety of the train is guaranteed to the maximum extent. And the embracing and buckling rail device is not easy to deform and damage.

    本发明公开了一种基于电磁驱动抱扣轨的高速铁路列车主动防脱轨方法,在高铁列车转向架的下侧可拆卸连接抱扣轨装置,抱扣轨装置可自动开合,列车正常行驶时,抱扣轨装置位于轨道外围,不影响列车正常行驶;列车在突发地震作用下出现脱轨倾向时,抱扣轨装置的扣轨组件先缩小与轨道之间的间隙处于抱轨状态,然后通过电磁力驱动抱扣轨组件的扣轨执行组件快速弹出同时扣住轨道翼缘两侧面和轨道腹板两侧面。在遇到地震作用时,给抱扣轨装置的抱扣轨组件通电,通过强大的电磁力驱动扣轨执行组件同时扣住轨道翼缘两侧面和轨道腹板两侧面,将列车锁定于轨道上避免倾覆,限制列车侧向脱轨和向上跳轨,最大限度保证列车安全。且抱扣轨装置不易出现变形损坏。
