According to the technical scheme, when a mechanical bridge is withdrawn, a swing frame and a basic arm are subjected to amplitude variation to a bridge picking position, the amplitude variation angle of a turnover arm and the telescopic length of a telescopic arm are adjusted according to the height difference and the position of the bridge and the erection mechanism, and an erection vehicle is aligned with the center of the bridge to move forwards; the front bridge picking oil cylinder plug pin is aligned with a hole groove in a bridge and then stretches out to be inserted into the hole groove, the overturning arm amplitude-variable oil cylinder drives the overturning arm to change amplitude upwards, meanwhile, the telescopic arm amplitude-variable oil cylinder drives the telescopic arm to retract, the longitudinal position and angle of the bridge and the erecting vehicle are adjusted, and after the bridge and an erecting vehicle connecting port are aligned and fixedly connected, the front bridge picking oi
