The utility model discloses a remote hydraulic well opening and closing device used for oil-gas well mouth emergency rescue. The remote hydraulic well opening and closing device used for the oil-gas well mouth emergency rescue is designed for conducting quick, safe and effective emergent shut of a burning well mouth in an oil-gas well accident. The remote hydraulic well opening and closing device used for the oil-gas well mouth emergency rescue is formed by connecting an oil tank, a hydraulic pump, an overflow valve, a switching valve, and a pressure regulating valve. A hydraulic power station is connected with a hydraulic gerotor motor through hydraulic pipelines, a balancing bar is fixed on an operation vehicle through hinge pins and a holder, the hydraulic gerotor motor is fixed on the balancing bar, an output end of the hydraulic gerotor motor is connected with a bevel gear set through a transmission shaft, and an output end of the bevel gear set is connected with a wheel claw. According to the remote hydraulic well opening and closing device used for the oil-gas well mouth emergency rescue, increased mechanical torque can be directly exerted on a gate of an accident well mouth, the emergency shut of the gate is achieved in the first time, life safety of field staff is guaranteed, and the environment is prevented from being seriously polluted. The remote hydraulic well opening and closing device used for the oil-gas well mouth emergency rescue can be widely used for opening and closing operation of a manually operated actuating mechanism of large-sized hydraulic ball valves in emergency circumstances.
