Bridge erecting machine and method for erecting spliced wide girders
The invention provides a bridge erecting machine for erecting spliced wide girders and a bridge erecting method, and belongs to the technical field of bridge engineering. The bridge erecting machine comprises a top frame and first supporting legs, wherein the top frame at least comprises two transverse bearing girders; the number of the first supporting legs is one below each transverse bearing girder; the first supporting legs are connected with the transverse bearing girders in a sliding mode; and the first supporting legs are suitable for sliding to the positions of piers for supporting thespliced wide girders. According to the invention, after the position of the bridge pier of the spliced wide girders is changed in the transverse direction, the first supporting legs can slide along the transverse bearing girders, so that the positions of the first supporting legs and the transverse bearing girders are changed, and the first supporting legs are promoted to realize transverse spanchange until the first supporting legs slide to the bridge pier position for supporting the spliced wide girders; in the construction process of the spliced wide girders on the ramp, the working condition that two single-side trusses are arranged side by side can be met, the working condition that a single truss is arranged side by side with a main line box girder can also be met, and the universalization degree is high.
本发明提供了一种架设拼宽梁的架桥机及架桥方法，属于桥梁工程技术领域，该架桥机包括：顶框架，所述顶框架至少包括两个横向承载梁；第一支撑腿，所述第一支撑腿在每个所述横向承载梁的下方均设有一个，所述第一支撑腿与所述横向承载梁滑动连接，且所述第一支撑腿适于滑动至支撑拼宽梁的桥墩位置上。本发明中，在拼宽梁桥墩的位置在横向发生变化后，第一支撑腿能够沿着横向承载梁滑动，从而改变其与横向承载梁的位置，促使第一支撑腿实现横向变跨，直至滑动至支撑拼宽梁的桥墩位置上；在匝道上的拼宽梁施工过程中，其既能满足单边2榀并置的工况，也能满足单榀与主线箱梁并置的工况，通用化程度高。
