The invention discloses an active anti-derailment device capable of achieving mechanical multi-level adjustment for a high-speed train. Relates to the field of train safety. Comprising a body, the body is used for being connected to the bottom of a train, and distance sensors are arranged on the two sides of the body; an anti-falling assembly is arranged on the main body, the anti-falling assembly comprises two mechanical arms rotationally connected to the main body, the rotating axes of the mechanical arms are arranged in the vertical direction, and rolling wheels used for abutting against the inner side wall of a track are arranged at the ends, away from the main body, of the mechanical arms; the mechanical arm rotates to drive the rolling wheel to abut against or be separated from the inner side wall of the rail. The anti-disengaging assembly further comprises a driving assembly used for driving the mechanical arm to rotate. Through the arrangement of the mechanical arms, when a train has the risk of derailing, the mechanical arms can extend towards the two sides, and the rolling wheels abut against the inner side wall of the rail so as to prevent the train from derailing; meanwhile, the train can be prevented from jumping out of the rail by changing the angle of the idler wheel abutting against the inner side wall of the rail.

    本申请公开了一种高速列车可机械多层次调节的主动防脱轨装置;涉及列车安全领域;包括主体,所述主体用于连接在列车底部,所述主体两侧设有距离感应器;所述主体上设有防脱组件,所述防脱组件包括转动连接在所述主体上的两机械臂,所述机械臂的转动轴线沿竖直方向设置,所述机械臂远离所述主体的一端设有用于抵接轨道内侧壁的滚轮,所述机械臂转动以驱使所述滚轮抵接或脱离轨道内侧壁,所述防脱组件还包括用于驱使所述机械臂转动的驱动组件;本申请通过机械臂的设置,当列车产生脱轨的风险时,机械臂可以向两边伸展,滚轮抵接在轨道内侧壁从而防止列车脱轨;同时,改变滚轮抵接轨道内侧壁的角度还可以防止列车产生跳轨的情况。
