Front supporting structure of bridge girder erection machine and construction method of front supporting structure
The invention relates to a front supporting structure of a bridge girder erection machine and a construction method of the front supporting structure. The front supporting structure comprises front supporting leg assemblies, wherein the front supporting leg assemblies are installed on a main beam in a movable adjusting mode in the length direction of the main beam and are vertically arranged, and the height is adjustable; supporting beam assemblies which are rotatably connected between the two front supporting leg assemblies, wherein the length of the supporting beam assemblies is adjustable, the arrangement direction of the supporting beam assemblies is consistent with the width direction of the pier, and the supporting beam assemblies can adapt to the staggered state of the two front supporting leg assemblies by rotating and adjusting the supporting beam assemblies. The front supporting leg assemblies and the supporting beam assemblies are adjusted to adapt to construction of orthogonal bridges and skew bridges with different skew angles, the construction range is wide, passing of the road below is not affected by construction of the bridge erecting machine, high-cost huge cranes are not needed, and the safety risk problem that the crane turns over due to the fact that the prefabricated bridge plate is too heavy and the suspension arm is too long during crane construction is avoided.
本发明涉及一种架桥机的前支撑结构及其施工方法，包括：以可沿主梁长度方向移动调节的方式安装于主梁上的前支腿组件，竖向设置且高度可调；可转动地连接于两个前支腿组件之间的支撑梁组件，长度可调，支撑梁组件的设置方向与桥墩的宽度方向一致，通过转动调节支撑梁组件以使得支撑梁组件可适应两个前支腿组件呈相错开的状态。通过调节前支腿组件和支撑梁组件以适配正交桥、不同斜交角的斜交桥的施工，施工范围广，架桥机施工不会影响下方路面的通行，无需使用费用高昂的巨型吊车，避免了吊车施工时由于预制桥梁板过重、吊臂过长而导致吊车翻车的安全风险问题。
