The invention discloses an undercarriage emergency discharge actuation unlocking device based on load detection and a working method, and relates to the technical field of undercarriage emergency discharge actuation unlocking. The landing gear emergency discharge actuation unlocking device based on load detection comprises a piston rod, a load sensor, a motor, a speed reducer and a lead screw, the load sensor, the motor, the speed reducer and the lead screw are sequentially and coaxially arranged in the piston rod, and a nut in threaded connection with the lead screw is arranged on the lead screw and connected with one end of a push rod. The load sensor is used for making contact with the motor, the load sensor and the piston rod are relatively fixed, the motor drives the speed reducer to rotate, the speed reducer drives the lead screw to rotate, and the nut drives the push rod to move in the length direction of the lead screw. An in-place sensor is not needed, the weight of the mechanism is reduced, fault detection is convenient, and maintenance is easy.
