Detachable front supporting leg structure for wide-body bridge girder erection machine and use method of detachable front supporting leg structure
The invention discloses a detachable front supporting leg structure for a wide-body bridge erecting machine and a using method of the detachable front supporting leg structure, and relates to the technical field of bridge erecting machine frames. The bridge girder erection machine comprises two longitudinal trusses and a bridge girder erection machine main beam, the two longitudinal trusses are located at one end of the top of the bridge girder erection machine main beam respectively, and a first front supporting leg assembly, a second supporting leg assembly and a first rear supporting leg assembly are assembled at the two ends of the bottom of the bridge girder erection machine main beam respectively. The first rear supporting leg assembly is located between the second supporting leg assembly and the first front supporting leg assembly. Through a series of structural improvements, when the bridge girder erection machine forwards paves a steel main beam, a bridge rail and the like, the first front supporting leg does not need to be integrally dismantled, and only connecting bolts between the first front supporting leg supporting column and the first front supporting leg lower column need to be dismantled, and then a hydraulic pump is operated to achieve upward folding of the two front supporting leg supporting columns. The transition and hoisting efficiency of the bridge girder erection machine is greatly improved, and safety risks are reduced.
本发明公开了一种用于宽体架桥机的可拆卸前支腿结构及其使用方法，涉及架桥机架技术领域。本发明包括两个纵行桁车和架桥机主梁，且两个纵行桁车分别位于架桥机主梁顶部的一端，架桥机主梁底部的两端均分别装配了第一前支腿总成、第二支腿总成和第一后支腿总成，第一后支腿总成位于第二支腿总成和第一前支腿总成之间。本发明通过一系列结构的改进，使得架桥机向前铺设钢主梁、桥轨等的时候不需要整体拆除第一前支腿,只需要拆卸掉第一前支腿支撑柱和第一前支腿下柱之间的连接螺栓后操纵液压泵实现两个前支腿支撑柱分别向上折叠,大大提高架桥机转场及吊装效率,降低安全风险。
