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.
