Bridge erecting machine and construction method thereof
The invention relates to the technical field of bridge girder erection machine construction, in particular to a bridge girder erection machine and a construction method thereof. The bridge girder erection machine comprises a main girder, two longitudinal ends of the main girder are respectively provided with a front guide beam and a rear guide beam, the front guide beam and/or the rear guide beam comprises a plurality of sections of assembly units, and any two adjacent sections of assembly units are detachably connected; the main crown block is movably arranged on at least one of the main beam, the front guide beam and the rear guide beam; a plurality of groups of hangers, one end of each hanger is suspended and moved by the main crown block and is suitable for being selectively suspended on the main beam, the other end of each hanger is fixedly connected with a segmental beam, and any group of hangers is suitable for being suspended with the adjacent hangers in a staggered manner, so that the segmental beams are arranged in a staggered manner along the height direction; and the main crown block is suitable for driving the hanger to move longitudinally or transversely or move up and down or rotate. According to the bridge erecting machine provided by the invention, through hole forward stretching can be carried out in a narrow construction site with obstacles at a bridge head, and girder erection is successfully completed.
本发明涉及架桥机施工技术领域，具体涉及一种架桥机及其施工方法。所述种架桥机包括：主梁，其纵向两端分别设置有前导梁和后导梁，所述前导梁和/或后导梁包括若干节拼装单元，且任意相邻两节所述拼装单元可拆连接；主天车，活动设置于所述主梁、所述前导梁和所述后导梁的至少其中一个上；若干组吊挂，所述吊挂一端经由所述主天车悬吊移动并适于选择性悬挂于所述主梁上，所述吊挂另一端固定连接节段梁，任意一组所述吊挂适于与相邻所述吊挂错层悬挂以使节段梁沿高度方向彼此错位设置；所述主天车适于带动所述吊挂纵向移动或横向移动或升降移动或旋转运动。本发明提供的种架桥机，在桥头有障碍的狭小施工场地能够进行过孔前伸，成功完成架梁。
