A hydraulic walking type automatic walking mechanism comprises a guide rail, a counterforce base, a hydraulic oil cylinder and a sliding seat. The counterforce base and the sliding seat are installed on the guide rail. One end of the hydraulic oil cylinder is connected with the counterforce base, and the other end of the hydraulic oil cylinder is connected with the sliding seat. The guide rail is a box beam and the upper end face of the guide rail is provided with a long-hole-shaped safety pin groove. C-shaped inverted hooks are arranged on the two sides of the counterforce base and the counterforce base is provided with a guide groove which is connected with a safety pin. The safety pin is provided with a safety pin bottom surface which is provided with a safety pin oblique angle, and the safety pin is connected with the counterforce base through a tension spring. The problem of complexity in operating hydraulic walking type walking mechanisms is solved, and the automation in the walking type walking process is achieved. The hydraulic walking type automatic walking mechanism has the characteristics of being simple in structure, convenient to operate and high in efficiency and is applicable to various large cranes and other engineering machines.
