The invention discloses a rail transit vehicle reverse sliding prevention device which comprises bases symmetrically installed on the bottom face of a vehicle frame, a supporting barrel is vertically arranged in the middle of each base, the bases and the supporting barrels form a T shape, and a guide rod on each supporting barrel extends out of the bottom end of the corresponding supporting barrel and is fixedly connected with the middle of a double-end hydraulic cylinder. The two ends of the top face of the double-end hydraulic cylinder are fixedly connected with the base through hydraulic ejector rods, the double-end hydraulic cylinder, the hydraulic ejector rods and the base form a triangular structure, and the two movable ends of the double-head hydraulic cylinder are movably connected with iron shoes of a triangular structure. According to the device, the hydraulic ejector rod and the double-end hydraulic cylinder extend in sequence, the double-end hydraulic cylinder can move downwards through unfolding of the hydraulic ejector rod, stable ascending or descending of the double-end hydraulic cylinder is achieved under the cooperation effect of the supporting barrel and the guide rod, and after the double-end hydraulic cylinder descends to the designated position, the two movable ends extend out to feed iron shoes into the positions between the wheels and the track, so that the iron shoes are conveyed to position between wheels and a track, the iron shoes are attached to the wheels, and rolling of the wheels is hindered.

    本发明公开了一种轨道交通车辆防倒溜装置,包括对称安装在车架底面上的基座,所述基座的中部竖直布置有支撑筒,且基座与支撑筒构成T形,所述支撑筒上的导杆伸出支撑筒的底端并与双头液压缸的中部固定连接,所述双头液压缸顶面两端处均通过液压顶杆与基座固定连接,且双头液压缸、液压顶杆和基座构成三角形结构,所述双头液压缸的两活动端均活动连接有三角形结构的铁鞋。本发明中,液压顶杆和双头液压缸先后伸展,液压顶杆的展开可以将双头液压缸下移,且在支撑筒和导杆的配合作用下,实现双头液压缸的平稳上升或下降,待双头液压缸下降到指定位置后,两活动端伸展出去,将铁鞋送入车轮和轨道之间,铁鞋与车轮贴合,实现车轮滚动的阻碍。
