Assembling method of supporting legs in bridge girder erection machine
The invention discloses an assembling method of supporting legs in a bridge girder erection machine, and relates to the technical field of bridge erection construction, which comprises the following steps of: independently manufacturing a connecting beam, a stand column and a lower cross beam according to a drawing, and drawing ground samples of the connecting beam, the stand column and the lower cross beam on a workshop platform according to the drawing; the connecting flanges except for the connecting beams and the main beams are inserted into the connecting seams of the connecting beams in groups to be matched with the connecting beams, three datum lines are delimited on the two connecting beams, three datum lines are correspondingly determined on the two main beams of the bridge erecting machine, the connecting beams and the main beams are correspondingly matched when the three datum lines coincide, and actual assembling is carried out according to the connecting beams and the main beams. According to the assembling method of the middle supporting leg of the bridge girder erection machine, overall scribing and lofting are conducted on the middle supporting leg on the horizontal platform, all parts are assembled, all connecting flange plates are subjected to running-in, and therefore it is guaranteed that all connecting flange holes can be correctly connected. Vertical and horizontal datum lines and a center line are marked on the connecting beam and aligned with a center line on the main beam to check the size, and then a connecting flange is matched, so that the mounting precision of the middle supporting leg and the main beam is ensured.
本发明公开了一种架桥机中支腿的组立方法，涉及桥梁架设施工技术领域，包括将联系梁、立柱、下横梁按图纸单独制作完成，按图纸在车间平台上划好联系梁、立柱、下横梁地样，将除联系梁与主梁之间的各连接法兰成组插入各件的连接缝与各件研配在一起，在两根联系梁上划定三根基准线，在两架桥机主梁对应确定三根基准线，在三线重合时将联系梁与主梁对应研配，并以此进行实际组装。本发明设计的架桥机中支腿的组立方法，为中支腿在水平平台上整体划线放样并组立各部件，配研各连接法兰板，以保证各连接法兰孔能够正确连接。通过在联系梁上划垂直、水平基准线及中心线与主梁上的中心线对位检查尺寸后研配好连接法兰，保证中支腿与主梁的安装精度。
