Front supporting leg diagonal bracing structure of bridge girder erection machine and construction method
The invention relates to the technical field of bridge construction, in particular to a diagonal bracing structure of a front supporting leg of a bridge erecting machine and a construction method, the diagonal bracing structure of the front supporting leg of the bridge erecting machine is located between the front supporting leg of the bridge erecting machine and an erected box girder and used for fixing and supporting the front supporting leg of the bridge erecting machine on a girder head of the erected box girder, and the diagonal bracing structure comprises a diagonal bracing rod and a supporting rod, the fixing mechanism is arranged at the lower end of the inclined supporting rod and comprises a first fixing piece arranged on the upper side of the girder head of the erected box girder and hinged to the lower end of the inclined supporting rod. The second fixing piece is arranged on the lower side of the front end of the first fixing piece, the rear side of the second fixing piece abuts against the front side of the girder head of the erected box girder, and the second fixing piece comprises a protruding block which is vertically arranged on the rear side of the second fixing piece and located below the top wall of the erected box girder; the first screw rod is in self-locking threaded connection with the convex block, and the upper end of the first screw rod penetrates through the convex block from bottom to top and is perpendicular to the top wall. According to the front supporting leg diagonal bracing structure of the bridge girder erection machine, the construction efficiency of the bridge girder erection machine is improved, and the reliability of the front supporting leg diagonal bracing structure is improved.
本发明一种架桥机前支腿斜撑结构及施工方法，涉及桥梁施工技术领域，架桥机前支腿斜撑结构位于架桥机的前支腿和已架箱梁之间，用于固定和支撑架桥机的前支腿于已架箱梁梁头上，包括：斜撑杆，其上端与前支腿铰接；固定机构，其设置在斜撑杆下端，包括：第一固定件，其设置在已架箱梁梁头上侧，且与斜撑杆下端铰接；第二固定件，其设置在第一固定件前端下侧，且其后侧与已架箱梁梁头前侧抵接，第二固定件包括：凸块，其垂直设置在第二固定件后侧，且位于已架箱梁的顶壁下方；第一螺杆，其与凸块自锁螺纹连接，上端从下往上穿过所述凸块且与顶壁垂直。本发明提供的架桥机前支腿斜撑结构，提高架桥机的施工效率，以及前支腿斜撑机构的可靠性。
