Re-railing device suitable for rail car

A rerailing device suitable for a rail car comprises a rerailing part. The number of the re-railing parts is two, and the re-railing parts are symmetrically arranged on the two sides of the rail car. The rerailing part comprises a push-back mechanism, a horizontal sliding rail, a lifting mechanism, an angle adjusting mechanism, a double-sided sliding rail piece, a propelling mechanism, a rerailing device, a PLC and a detection mechanism; the push-back mechanism and the horizontal sliding rail are both arranged on the side wall of the rail car. The lifting mechanism is arranged on the horizontal sliding rail; an angle adjusting mechanism is arranged at the bottom end of the lifting mechanism; the upper end of the double-face sliding rail piece is connected with the angle adjusting mechanism, and the lower end of the double-face sliding rail piece is connected with the propelling mechanism. And the detection mechanism and the rerailer are arranged on the propelling mechanism. The rail car re-railing device impr
