The invention relates to an anti-derailment device which is arranged at the bottom of a train and comprises a first overturning support, a second overturning support and a third overturning support, and the first overturning support comprises a first rotating seat and a first supporting rod which are hinged to each other; the limiting assembly is arranged at the end, away from the first rotating base, of the first supporting rod. The first driving piece can drive the first supporting rod to rotate to a first working position; when the first supporting rod is at the first working position, the limiting assembly is in limiting fit with the track in the width direction of the track; and the control system is electrically connected with the first driving piece, and the control system detects the running state of the train in real time and sends an action instruction to the first driving piece according to the running state. Compared with an anti-derailment device which is arranged at the bottom of a train and cannot be folded in the prior art, the anti-derailment device does not occupy too much vertical space to avoid collision with foreign matter on a railway line and does not make contact with a rail in a non-working state, so that the working time is shortened, and the service life of the anti-derailment device is prolonged.

    本发明涉及一种防脱轨装置,设置在列车的底部,包括:第一翻转支架,第一翻转支架包括相互铰接的第一转动座和第一支杆;限位组件,其设置在第一支杆远离第一转动座的一端;第一驱动件,第一驱动件可带动第一支杆转动至第一工作位置;第一支杆在第一工作位置时,限位组件与轨道在轨道的宽度方向限位配合;以及,控制系统,控制系统与第一驱动件电连接,控制系统实时检测列车的行驶状态,并根据行驶状态向第一驱动件发出动作指令。相对于现有技术中设置在列车底部不可折叠的防脱轨装置,本发明的防脱轨装置在非工作状态下,即不过多的占用竖向空间避免与铁路线上的异物撞击,也不与轨道相互接触,因此减少了其工作时长,延长了其使用寿命。
