Mounting device for electric power engineering construction

The utility model discloses a mounting device for electric power engineering construction, which comprises a bottom plate, and a push rod is fixedly mounted on the upper end face of the bottom plate. By arranging a second servo motor, a second rod, a driving gear, driven gears, a second cavity, a threaded sleeve, a railing column, a protective railing and a second threaded rod, when a bottom plate moves to a construction site, after a constructor stands on a platform plate, the second servo motor is started, the output end of the second servo motor drives the second rod to rotate, and the driving gear drives the four driven gears to rotate; four threaded sleeves are driven by four driven gears to rotate, so that four second threaded rods move towards the upper portion of the platform plate in the four threaded sleeves in a threaded mode and drive the four fence columns and the protective railings to move upwards correspondingly, and when the four protective railings ascend to the height matched with the heigh
