Bridge girder erection machine main girder structure suitable for multiple working conditions and assembly technology of bridge girder erection machine main girder structure
The invention discloses a bridge girder erection machine girder structure suitable for multiple working conditions and an assembling technology thereof.The bridge girder erection machine girder structure comprises a box-type girder structure, a front transverse connecting beam and a rear transverse connecting beam, the box-type girder structure comprises upper-layer girders and lower-layer girders, the two upper-layer girders are fixedly connected with the two ends of the front transverse connecting beam and the two ends of the rear transverse connecting beam, the box-type girder structure is made of high-strength steel, and the lower-layer girders are fixedly connected with the two ends of the front transverse connecting beam and the two ends of the rear transverse connecting beam; the upper-layer main beam and the lower-layer main beam are both single-box type beams formed by splicing a plurality of sections, in the upper-layer main beam and the lower-layer main beam, the adjacent sections are connected through pin shafts, the sections between layers are fixedly connected through bolts, an interlayer base plate is arranged between the upper-layer main beam and the lower-layer main beam, and the interlayer base plate is arranged between the upper-layer main beam and the lower-layer main beam. The bridge girder erection machine has multiple functions, is suitable for multiple working conditions, can be used for erecting a wide variety of box girders, has light-weight combination of a main machine structure, and improves the construction operation performance and the application range of hoisting machinery.
本发明公开一种适用于多工况的架桥机主梁结构及其装配工艺，包括箱型主梁结构和前、后横连梁，所述箱型主梁结构包括上层主梁和下层主梁，两根上层主梁与前、后横联梁的两端固定连接，其中箱型主梁结构采用高强钢材制作而成，上层主梁和下层主梁均为多个节段拼接而成的单箱式梁，所述上层主梁和下层主梁中，相邻节段之间通过销轴完成连接，层与层之间的节段采用螺栓完成固定连接，位于上层主梁和下层主梁之间设置有夹层垫板，本发明实现了架桥机一机多能，适用工况多、可架箱梁种类广、主机结构轻量化组合，提高了起重机械施工作业性能和适用范围。
