Curve hole passing method
The invention relates to the technical field of bridge erection, and provides a curved hole passing method which is applied to a bridge girder erection machine, and the method comprises the steps that a rear supporting leg and a front temporary supporting leg are folded so that the rear supporting leg and the front temporary supporting leg can be suspended, and a main beam is driven to move by a first distance in the advancing direction of bridge erection; the middle supporting leg is driven to move towards the outer side of the curve of the curvature bridge section to be erected by a second distance; driving the middle supporting leg to move towards the advancing direction of bridge erection for a third distance; erecting a middle supporting leg, folding a rear supporting leg, and driving the main beam to move towards the forward direction of bridge erection by a fourth distance; the middle supporting leg and the front supporting leg are driven to drive the main beam to move towards the inner side of the curve of the curvature bridge section to be erected by a fifth distance; the middle supporting leg is driven to move towards the outer side of the curve of the curvature bridge section to be erected by a sixth distance; and driving the middle supporting leg to move a seventh distance towards the advancing direction of the bridge erection, and driving the front supporting leg to move an eighth distance towards the advancing direction of the bridge erection. By means of the method, the safety and construction efficiency of hole passing operation can be improved.
本发明涉及桥梁架设技术领域，并提供一种曲线过孔方法，应用于架桥机，所述方法包括：收后支腿和前临时支腿，以使后支腿和前临时支腿悬空，驱动主梁朝向桥梁架设前进方向移动第一距离；驱动中支腿朝向待架设曲率桥梁节段的曲线外侧移动第二距离；驱动中支腿朝向桥梁架设前进方向移动第三距离；立中支腿，收后支腿，驱动主梁朝向桥梁架设前进方向移动第四距离；驱动中支腿和前支腿带动主梁朝向待架设曲率桥梁节段的曲线内侧移动第五距离；驱动中支腿朝向待架设曲率桥梁节段的曲线外侧移动第六距离；驱动中支腿朝向桥梁架设前进方向移动第七距离，驱动前支腿朝向桥梁架设前进方向移动第八距离。通过本方法，可提高过孔作业的安全性和施工效率。
