Railway locomotive rescue hoisting machine tool

The invention discloses a railway locomotive rescue hoisting machine tool which comprises a base, a lifting hook support, a hoisting pin shaft, an adjusting oil cylinder and a hoisting arm, the adjusting oil cylinder and the hoisting arm are symmetrically arranged at the two ends of the base, the lifting hook support is rotationally connected to the top of the base, the hoisting pin shaft is connected with the lifting hook support, the hoisting arm is rotationally connected with the base, and the adjusting oil cylinder is arranged below the hoisting arm. One end of the adjusting oil cylinder is rotationally connected with the base, and an output shaft of the adjusting oil cylinder is rotationally connected with the bottom end of the lifting arm. The overall size of the hoisting machine tool is small, so that the hoisting operation of the locomotive can be realized in a low and narrow space; the angle of the hoisting arm can be adjusted by adjusting the adjusting oil cylinder, so that the length of the hoistin
