Dragging device and method for construction of bridge crossing railway line
The invention discloses a dragging device and method for construction of a bridge crossing a railway line, and relates to the technical field of bridge construction dragging. The device comprises two supporting cross beams and a to-be-dragged bridge box girder, and further comprises an erecting and dragging unit which is arranged between the two supporting cross beams and internally comprises an erecting assembly and a limiting assembly; the pushing unit is arranged between the two supporting cross beams, a pushing assembly and an adjusting assembly are arranged in the pushing unit, and the pushing assembly is used for achieving dragging and pushing of the bridge box girder. The device has the advantages that a clamping erection mounting mode is adopted, the stability of the bridge box girder in the dragging process can be guaranteed, real-time horizontal position deviation rectification can be conducted in cooperation with a deviation rectification oil cylinder in the push-pull process, the accuracy of the dragging position of the bridge box girder is guaranteed, and the safety of the bridge box girder is guaranteed. And meanwhile, dragging fixed-distance movement of the bridge box girder can be achieved in a rear hydraulic pushing mode, accurate control over the position of the bridge box girder is achieved, and convenience of follow-up splicing installation of the bridge box girder is improved.
本发明公开了一种横跨铁路线的大桥施工用拖拉装置及方法，涉及桥梁施工拖拉的技术领域。本发明包括两根支撑横梁以及待拖拉的桥梁箱梁，还包括：架设拖拉单元，设置于两根支撑横梁之间，其内包括架设组件与限位组件；推移单元，设置于两根支撑横梁之间，其内包括推移组件与调节组件，其中推移组件用于实现桥梁箱梁的拖拉推移。优点在于：本发明采用夹持架设的安装方式，既能够保证桥梁箱梁拖拉过程的稳定性，又可配合纠偏油缸在推拉过程中进行实时的水平位置纠偏，确保桥梁箱梁拖拉位置的准确性，同时通过采用后部液压推移的方式可实现桥梁箱梁的拖拉定距移动，实现桥梁箱梁位置的精确控制，提高后续桥梁箱梁拼接安装的便捷性。
