Cantilever bridge girder erection machine and modular assembling method of supporting truss system of cantilever bridge girder erection machine
The invention discloses a cantilever bridge girder erection machine and a modular assembling method of a supporting truss system of the cantilever bridge girder erection machine. The cantilever bridge girder erection machine comprises a supporting truss system, and the supporting truss system is formed by assembling a plurality of modular components prefabricated in a factory on site; the modularized components prefabricated in each factory comprise a movable front supporting rod module, a front supporting point parallel connection, a movable rear supporting rod module, a rear supporting point parallel connection, an anchoring section truss connecting section and a cantilever section truss connecting section. The two movable front supporting rod modules are spliced in a parallel connection mode through a front supporting point arranged between the two movable front supporting rod modules to form a movable front supporting rod segment. The two movable rear supporting rod modules are horizontally connected through a rear supporting point arranged between the two movable rear supporting rod modules to be spliced to form a movable rear supporting rod section; the anchoring section truss connecting section and the cantilever section truss connecting section are arranged on the two sides of the movable front supporting rod section respectively. Therefore, on the premise that the requirements for rigidity and bearing capacity are met, on-site assembly precision is effectively improved, and on-site operation difficulty and risks are reduced.
本发明公开了一种悬臂架桥机及其支承桁架体系的模块化拼装方法。悬臂架桥机包括支承桁架体系，支承桁架体系采用多个工厂预制的模块化构件在现场进行组装而成；各工厂预制的模块化构件包括可移动前支杆模块、前支点平联、可移动后支杆模块、后支点平联、锚固段桁架连接节段、悬臂段桁架连接节段；两个可移动前支杆模块通过置于其间的前支点平联拼接形成可移动前支杆节段；两个可移动后支杆模块通过置于其间的后支点平联而拼接形成可移动后支杆节段；锚固段桁架连接节段以及悬臂段桁架连接节段分设在可移动前支杆节段的两侧。由此可见，本发明在满足自身刚度和承载力需求的前提下，有效地提高了现场拼装精度，降低现场作业难度以及风险。
