The invention provides a high-thrust hydraulic jacking device for a diesel engine generator, and belongs to the technical field of heavy equipment installation. Comprising a hydraulic jack, a two-position four-way hydraulic valve, a hydraulic cylinder, a threaded piston rod, a bracket and a motor, an oil outlet and an oil return opening in the left end of the hydraulic cylinder are connected with an oil inlet and an oil outlet of the hydraulic jack through a two-position four-way hydraulic valve, a hydraulic piston is arranged in the hydraulic cylinder, the right end of the hydraulic cylinder is fixedly connected with a support, the right end of the support is fixedly connected with a motor, and a sleeve is coaxially and fixedly connected to an output shaft of the motor. The threaded piston rod can freely move in the sleeve in the axial direction and is screwed with a center thread at the left end of the support, and the left end of the threaded piston rod is freely and rotatably connected with the hydraulic piston. The device is small in size, large in jacking thrust, high in adjusting precision and easy to operate, and the high-precision adjusting efficiency of heavy equipment is greatly improved.
