Supporting leg structure of bridge erecting machine for erecting bridge in tunnel
The invention belongs to the technical field of bridge construction, and particularly relates to a supporting leg structure of a bridge erecting machine for erecting a bridge in a tunnel. The structure comprises a bridge erecting machine base, a supporting leg main body is arranged at the bottom of the bridge erecting machine base, steel cable drums are mounted on the front and rear sides of the supporting leg main body, hydraulic cylinders are arranged at the bottoms of the steel cable drums, a movable leg is arranged at the bottom of the supporting leg main body, a supporting leg base is arranged at the bottom of the movable leg, a supporting leg foundation is arranged at the bottom of the supporting leg base, a connecting protruding block is arranged in the middle of the supporting leg foundation, and steel cable hubs are installed at the two ends of the supporting leg foundation. According to the supporting leg structure for erecting the bridge in the tunnel, the supporting leg foundation and the supporting leg main body can be stably connected together through a base fixing groove and a connecting hole, the supporting leg main body can bear oblique tension of a steel cable through the steel cable hubs and the steel cable drums, the height of the base of a bridge erecting machine can be set according to requirements through the hydraulic cylinders, and the height of the base of the bridge erecting machine can be accurately adjusted in a small range through a cylindrical hydraulic pump.
本发明属于桥梁建设技术领域，尤其为一种架桥机隧道内架设桥梁的支腿结构，包括架桥机底座，所述架桥机底座底部设置有支腿主体，所述支腿主体前后两边都安装有钢索卷筒，所述钢索卷筒底部设置有液压缸，所述支腿主体底部设置有活动腿，所述活动腿底部设置有支腿底座，所述支腿底座底部设置有支腿基础，所述支腿基础中间设置有连接凸块，所述支腿基础两端安装有钢索轮毂；本发明的隧道内架设桥梁的支腿结构，利用底座固定槽和连接孔可以使支腿基础与支腿主体稳固的连接在一起，利用钢索轮毂和钢索卷筒可使支腿主体受到钢索的斜向拉力，利用液压缸使架桥机底座高度可依据要求设置，而柱形液压泵使架桥机底座的高度可以在小范围内精确调节。
