The invention discloses a high-safety rail car door back-pushing system. The system comprises two symmetrically-arranged fork chain seats, door leaf bodies on the corresponding sides are fixed to thelower portions of the fork chain seats, the fork chain seats are connected to horizontal pan head shafts of the door leaf bodies in a sleeving mode, the two ends of the pan head shafts are fixed to the lower portions of fork chain links, and the upper portions of the fork chain links are fixedly connected with a driving mechanism. A first shaft sleeve, an elastic energy storage element and a second shaft sleeve are sequentially connected to the pan head shaft in a sleeving mode, and the distance between the first shaft sleeve and the second shaft sleeve is the limited back-pushing distance.

    本发明专利公开了一种安全性高的轨道车门回推系统,包括对称设置两片钗链座,各钗链座的下方固定有对应侧的门扇体,各钗链座套接在扇体水平的盘头轴上,盘头轴的两端固定在钗链节的下部,钗链节的上部与驱动机构固定连接,第一轴套、弹性储能元件、第二轴套依次套接在盘头轴上,第一轴套、第二轴套之间的距离为限制回推距离。
