The invention relates to the technical field of hydraulic steering devices, and provides an aircraft tractor hydraulic steering device which comprises an oil storage tank and a direction lever, one end of the oil storage tank is fixedly sleeved with a steering cylinder, the outer wall of the other end of the steering cylinder is sleeved with an anti-skid sleeve, a guide rod is movably sleeved with the anti-skid sleeve, and one end of the guide rod is fixedly connected with a steering arm. The end of the steering arm is movably connected with a wheel connecting rod, one end of the steering rod is hinged to a cross valve element, the two ends of the cross valve element are rotationally connected to a steering knuckle, one end of the steering knuckle is connected with a steering device, a hydraulic cylinder is arranged in the steering device, and the end, connected with the steering knuckle, of the hydraulic cylinder is fixedly provided with a hydraulic pump. A hydraulic rod is fixedly connected to the output end of the hydraulic pump and engaged with a piston rod. The hydraulic rod is driven to rotate by starting the hydraulic pump, the piston rod is driven to move in cooperation with the tooth groove, and by increasing the flow and pressure of hydraulic oil, the steering performance of a vehicle is improved, the steering torque of the vehicle is increased, and the optimal steering performance is achieved.
