A multifunctional longitudinal movement driving device for a bridge girder erection machine comprises a driving module arranged on a crown block of the bridge girder erection machine, driving chains on main beams of the bridge girder erection machine and a support rod mechanism between the crown block of the bridge girder erection machine and a main landing leg. Longitudinal movement of the crown block of the bridge girder erection machine and via holes of the main beams can be achieved by one drive mechanism; the problems of insufficient driving power, operation skid, difficult mechanism layout and the like of the bridge girder erection machine during long-span, large-tonnage and heavy-grade bridge construction can be solved; and the device has the characteristics of safety, stability, low cost, compact mechanism layout and the like.
