The invention provides a keel beam lifting and positioning system based on electric drive, which belongs to the technical field of aircraft assembly and comprises two groups of identical independent lifting systems, the two groups of identical independent lifting systems can form linkage and independently operate, and synchronous lifting and positioning and independent lifting fine adjustment are realized. Each independent lifting system comprises a right-angle hand-cranking speed reducer, a servo motor, a lifter push rod, supporting rods, a keel beam positioner and the like, the right-angle hand-cranking speed reducer is connected with the servo motor, the output end of the servo motor is connected with the lifter push rod to provide lifting power, and the supporting rods are arranged on the two sides of the lifter push rod and used for auxiliary supporting. And the keel beam positioner is used for positioning and locking the keel beam. The device is reliable in performance, and has relatively high overload capacity and relatively high precision; a double-system linkage design is adopted, the overall stability of the system is improved, and independent lifting can be achieved; an adjustable speed reducer is arranged, so that the lifting speed can be adjusted; the system is small in occupied space, simple in structure and convenient to operate; and the stroke protection function is achieved.
