Beam changing, jacking and longitudinal and transverse moving equipment of railway box type rigid frame bridge and construction method of beam changing, jacking and longitudinal and transverse moving equipment
The invention discloses beam changing jacking longitudinal and transverse moving equipment of a railway box type rigid frame bridge and a construction method, and belongs to the technical field of railway bridge construction. According to the construction method, a rail transportation beam body is adopted; comprising the following steps of separating a beam body, arranging beam changing jacking longitudinal and transverse moving equipment, making contact with the beam body, jacking the beam body, stopping lifting of the beam body, combining rails, longitudinally moving the beam body, lifting a rail car, rotating rail wheels of the rail car, laying a temporary ferry rail, falling the rail car from the rail, transversely moving the beam body, lifting the rail car, returning the rail wheels of the rail car, falling the rail car from the rail again and removing the beam body. Installing a new beam body; the beam body needing to be replaced does not need to be cut on site, and the operation period is short. The beam changing jacking longitudinal and transverse moving equipment comprises a track beam, a lifting mechanism and a track car. The longitudinal moving and transverse moving integrated function is achieved, jacking, longitudinal moving and transverse moving of a beam body can be safely and efficiently achieved in a narrow space, and interference to existing lines and under-bridge driving roads is greatly reduced.
本发明公开了一种铁路箱型刚构桥的换梁顶升纵横移装备及施工方法，属于铁路桥梁施工技术领域。其中，施工方法采用轨道运输梁体，包括以下步骤：分离梁体、设置换梁顶升纵横移装备、接触梁体、梁体顶升、停止梁体抬升、轨道连同、梁体纵移、轨道车抬升、旋转轨道车轨道轮、铺设临时摆渡轨道、轨道车落轨、梁体横移、轨道车抬升、轨道车轨道轮回位、轨道车再落轨、梁体移除、新梁体安装；无需对需要置换的梁体进行现场切割，作业周期短。本发明的换梁顶升纵横移装备包括轨道梁、升降机构和轨道车；具备纵移、横移一体功能，能够在狭小空间下安全高效地实现梁体的顶升、纵移和横移，大大减小了对既有线路和桥下行车道路的干扰。
