Bridge girder erection machine and girder erection and hole passing method thereof
The invention discloses a bridge girder erection machine and a girder erection and hole passing method thereof.The bridge girder erection machine comprises a main frame, a supporting leg assembly, a front crane carriage and a rear crane carriage, the main frame comprises two main girders, the two main girders are distributed in parallel at intervals, a connecting beam is arranged between the two main girders, and the supporting leg assembly comprises a front supporting leg, a middle supporting leg and a rear supporting leg; the middle supporting leg is rotatably matched with the main frame, the rear supporting leg is rotatably matched with the main frame, a first longitudinal moving assembly and a second longitudinal moving assembly are arranged on the middle supporting leg and the rear supporting leg respectively, and the middle supporting leg and the rear supporting leg move relative to a bridge through the first longitudinal moving assembly and the second longitudinal moving assembly. According to the bridge girder erection machine, supporting of a rear supporting leg is not needed during girder feeding, and the situation that unfavorable transverse bending moment is generated by a concrete girder flange due to supporting of the rear supporting leg during hole passing can be avoided.
本发明公开了一种一种架桥机及其架梁与过孔方法，包括主框架、支腿组件、前起重小车和后起重小车，所述主框架包括两个主梁，两个所述主梁平行间隔分布，且二者之间设有联系梁，所述支腿组件包括前支腿、中支腿、后支腿，所述后支腿与所述主框架转动配合，所述中支腿与所述后支腿上分别设有第一纵移组件和第二纵移组件，所述中支腿与所述后支腿通过所述第一纵移组件和所述第二纵移组件相对桥梁移动。根据本发明的架桥机可以在喂梁时无需后支腿支撑，还可以规避在过孔时因后支腿支撑导致砼梁翼缘产生不利的横向弯矩。
