Rapid transfer method and equipment of super-large bridge girder erection machine for assembled steel-concrete composite bridge

Abstract

The invention provides a rapid transfer method and equipment of a super-large bridge girder erection machine for an assembled steel-concrete composite bridge. The rapid transfer of the bridge girder erection machine is realized by using a front folding leg, a fixture crossbeam special for transferring and an anti-overturning leg. The involved equipment is simple in structure and high in transfer efficiency; when the bridge girder erection machine encounters the working conditions that the bridge girder erection machine performs integrated amplitude-change erection, integrally passes through atunnel, integrally returns to a starting point and integrally advances and transfers to the next installation location, the operations that the bridge girder erection machine performs integrated amplitude-change erection, integrally passes through the tunnel, integrally returns to the starting point and integrally advances and transfers can be completed without dismantling the main body of the bridge girder erection machine, thereby saving the construction cost, accelerating the construction progress and reducing the safety risk. The rapid transfer method and equipment of the super-large bridge girder erection machine for the assembled steel-concrete composite bridge are suitable for erection and installation of the assembled steel-concrete composite bridge and can be also applied to otherfields of similar structure types.

Description

technical field [0001] The invention relates to a fast transfer method and equipment for a super-large bridge erecting machine of an assembled steel-concrete composite bridge, which belongs to the field erection and installation equipment transfer technology for large-scale components, and is mainly used in the overall rapid variable-amplitude erection of super-large bridge erecting machines and the rapid passage of tunnels as a whole , the overall rapid return to the starting point, the overall rapid transfer to the next installation site, and can also be applied to other fields of similar structure types. Background technique [0002] Prefabricated steel bridges have been widely used all over the world. Bridges can be divided into reinforced concrete girder bridges, prestressed concrete girder bridges, steel structure girder bridges and concrete and steel composite structure girder bridges according to the different materials used. Reinforced concrete girder bridges mostly...
