Multifunctional front supporting leg mechanism of single-girder bridge girder erection machine
The invention relates to a multifunctional front supporting leg mechanism of a single-girder bridge girder erection machine, which comprises an upper cross beam, a first jacking oil cylinder, a first-stage telescopic column, a climbing oil cylinder, a conversion cross beam, a second-stage telescopic column, an oil cylinder bolt assembly, a first manual bolt assembly, a second manual bolt assembly and a ground anchor assembly, the upper cross beam is connected with first-level telescopic columns through first jacking oil cylinders and oil cylinder plug pin assemblies, the first-level telescopic columns are installed in sliding grooves in the two sides of the upper cross beam, inner column bodies of the first-level telescopic columns are used for sliding in the sliding grooves in the two sides of the upper cross beam, and outer column bodies of the first-level telescopic columns are connected with second-level telescopic columns through first manual plug pin assemblies. The second-level telescopic column is used for sliding in a sliding groove of the first-level telescopic column, the conversion cross beam and the second-level telescopic column are used for sliding in the sliding groove of the first-level telescopic column through a second manual bolt assembly, the middle of the second-level telescopic column is connected with a ground anchor assembly, and the ground anchor assembly is tightly connected and locked with the front two rows of lifting holes of the erected box girder through a tensioning device. And the overall stability of the front supporting leg can be greatly improved.
本发明涉及一种单主梁架桥机多功能型前支腿机构，包括上横梁、第一顶升油缸、一级伸缩柱、爬升油缸、转换横梁、二级伸缩柱、油缸插销组件、第一手动插销组件、第二手动插销组件和地锚组件，上横梁通过第一顶升油缸和油缸插销组件与一级伸缩柱相连，一级伸缩柱安装在上横梁两侧滑槽内，一级伸缩柱的内柱体用于在上横梁两侧滑槽内滑动，一级伸缩柱的外柱体通过第一手动插销组件与二级伸缩柱相连，二级伸缩柱用于在一级伸缩柱的滑槽内滑动，转换横梁通过第二手动插销组件与二级伸缩柱用于在一级伸缩柱的滑槽内滑动，二级伸缩柱中部与地锚组件相连，地锚组件通过拉紧装置与已架箱梁的前两排吊孔紧密拉接并锁紧，能够极大提升了前支腿的整体稳定性。
