The invention provides a hydraulic driving device, and relates to the technical field of driving devices, the hydraulic driving device comprises a bearing part, a traction rope, a reset rope, a driving assembly and a plurality of guide pulleys, and the guide pulleys are used for guiding the extension directions of the traction rope and the reset rope; the driving assembly comprises a pulley block, the pulley block comprises a first fixed pulley block, a first movable pulley block, a second movable pulley block and a second fixed pulley block, and the first movable pulley block and the second movable pulley block are connected through a support. The end, away from the bearing piece, of the reset rope alternately bypasses pulleys of the second fixed pulley block and the second movable pulley block. The driving assembly further comprises a thrust oil cylinder and a buffering oil cylinder, the thrust oil cylinder is used for driving the first movable pulley block and the second movable pulley block to move synchronously, and therefore high-speed acceleration of a large-mass load is achieved.
