description The invention discloses a hydraulic lifting device for a petroleum drilling machine. The hydraulic lifting device for the petroleum drilling machine comprises a lifting main machine, a lifting wire rope, a guiding pulley and an electric control system. The lifting main machine is fixed on a petroleum drilling frame, and comprises a lifting main machine cylinder body, a lifting main machine pistonrod, a movable pulley group and a static pulley group. A main shaft of the movable pulley group is perpendicular to a main shaft of the static pulley group in space, and the lifting main machine cylinder body is connected with an electric control system through a hydraulic pipeline and is connected with a hydraulic system in the petroleum drilling machine through the electric control system. One end of the lifting wire rope is fixed to the lifting main machine cylinder body, and the other end of the lifting wire rope penetrates through the movable pulley group and the static pulley group.
