摘要

A transportation and erection integrated machine with displacement platforms and a method for erecting a bridge using the same are provided. The transportation and erection integrated machine with displacement platforms comprises a girder transportation and erection equipment and a guide girder equipment with platform. The girder transportation and erection equipment comprises a main girder (2), front and rear running pulley groups (1, 5) and a lifting gear (4), the guide girder equipment with platform comprises a guide girder (10) with platform, a folding leg (7), front, middle and rear roller legs (11, 12, 13) and a girder erection trolley (6) arranged on the guide girder (10) with platform, and the displacement platforms (8) are fixed on both sides of the tail portion of the guide girder (10) with platform. When the bridge is erected, the front running pulley group (5) is moved to the displacement platforms (8), which can be lifted and folded according to conditions of the first and last bridge spans of different bridges, so that the bridge erection is achieved.
