Bridge erecting machine capable of realizing small curve line
The invention discloses a bridge girder erection machine capable of realizing a small curve line, and belongs to the technical field of bridge girder erection machines. A bridge girder erection machine capable of achieving a small curve line comprises a main beam arranged on a bridge, two crane carriages capable of moving in the length direction of the main beam are arranged on the main beam, the bridge girder erection machine further comprises a rear supporting leg, the rear supporting leg is arranged at the tail end of the main beam, and the main beam is rotationally provided with a mounting base connected with the rear supporting leg through a rotating shaft; the front supporting leg is arranged at the front end of the main beam, and a position adjusting mechanism used for driving the main beam to rotate is arranged on the front supporting leg; the middle supporting leg is arranged on the main beam and is arranged between the front supporting leg and the rear supporting leg; the main beam drives the box beam to deflect through the position adjusting mechanism, so that the box beam is convenient for building a small-curve line, the connection stability between the front supporting leg and the bridge is enhanced through the auxiliary supporting mechanism, the main beam and the box beam which deflect out of a straight line are effectively supported, the transverse deflection stability of a main beam system is guaranteed, and the requirement of small-radius curve span construction is met.
本发明公开了一种可以实现小曲线线路的架桥机，属于架桥机技术领域。一种可以实现小曲线线路的架桥机，包括设置于桥梁上的主梁，主梁上设置有两个可沿其长度方向移动的起重小车，还包括：后支腿，后支腿设置在主梁的末端，主梁通过转轴转动设置有与后支腿相连的安装座；前支腿，前支腿设置在主梁的前端，前支腿上设置有用于驱动主梁转动的调位机构；中支腿，中支腿设置在主梁上且置于前支腿和后支腿之间；本发明通过调位机构使主梁带动箱梁偏转，使箱梁便于小曲线线路的搭建，通过辅助支撑机构加强前支腿与桥梁之间连接稳固性，有效对偏移出直线的主梁和箱梁支撑，保障了主梁系统的横向偏移稳定，满足小半径曲线跨度施工的需求。
