The invention discloses a pump valve joint control hydraulic steering gear device based on a frequency conversion technology and a control method. The pump valve joint control hydraulic steering gear device comprises a pump control hydraulic loop and a valve control hydraulic loop. The pump control hydraulic loop is composed of a frequency conversion hydraulic pump, a one-way valve and a two-way overflow valve, wherein the frequency conversion hydraulic pump is connected with a frequency conversion motor. The valve control hydraulic loop is composed of an electric-hydraulic direction valve, a low-pressure overflow valve, a load valve, an overflow valve and an auxiliary oil pump, wherein the auxiliary oil pump is further connected with an auxiliary motor and an oil tank. The pump control hydraulic loop and the valve control hydraulic loop are connected in parallel and then connected with a shifting fork type steering mechanism set through manual isolation valves. By the adoption of the control method for the device, the angle value of rudder blades is monitored, so that the frequency conversion motor is used for working independently or used for working in cooperation with electromagnetic valves. By the adoption of the pump valve joint control hydraulic steering gear device based on the frequency conversion technology, the valve control technology and the pump control technology are combined, the steering speed is high, steering operation is convenient, energy consumption is low, service life is long, practicality is high, and the market prospect is wide.
