The invention discloses a self-walking multi-degree-of-freedom tensioning jack hydraulic trolley. The self-walking multi-degree-of-freedom tensioning jack hydraulic trolley comprises a longitudinal moving mechanism capable of moving in the longitudinal direction, a lifting mechanism capable of rising and falling in the vertical direction is arranged on the longitudinal moving mechanism, a tensioning jack is arranged on the lifting mechanism, and an adjusting mechanism used for adjusting an inclined angle and transverse position of the tensioning jack is arranged between the lifting mechanism and the tensioning jack. According to the self-walking multi-degree-of-freedom tensioning jack hydraulic trolley, tension of inhaul cable prestress can be realized, the jack further can be rapidly andmulti-directionally translated and rotated, and rapid positioning and station switching are achieved.
