The invention discloses a winch pressurization control device as well as a control method and a rotary drilling rig of the winch pressurization control device, and relates to the field of engineering machinery control. The winch pressurization control device comprises a pressurizing winch pressure switch, a sensor, a controller, a pressurization control electromagnetic valve and a pressurizing winch brake electromagnetic valve. When winch pressurization is abnormal, the pressurizing winch stops pressurizing, so that the structural damage of the rig can be avoided, and the safety and the reliability of model construction of winch pressurization are improved.
