Reverse lifting system and method for dismantling bailey beam support
The invention discloses a reverse lifting system and method for dismantling a bailey beam support. The system comprises a reverse lifting device and a monitoring device connected with the reverse lifting device, the reverse lifting device comprises at least two reverse lifting mechanisms which are the same in structure and are arranged at intervals in the longitudinal direction of a simply-supported box girder, each reverse lifting mechanism comprises a reverse lifting beam, a counter-force frame, a loading beam and a hydraulic jack, and each reverse lifting beam, the simply-supported box girder, each loading beam and each counter-force frame are connected through lifting rods. The method comprises the steps of 1 mounting and adjusting the counter-force frames, the hydraulic jacks and the loading beams; 2 mounting lifting rods and the reverse lifting beams; 3 dismounting sand cylinders and steel pipe columns; ad 4 falling the bailey beam support. The system is simple in structure, the levelness of the bailey beam support in the falling process can be improved, the falling speed and safety of the bailey beam support can be improved, the construction period can be shortened, and the construction cost can be saved.
本发明公开了一种拆除贝雷梁支架的反向吊落系统及方法，该系统包括反向吊落装置和与反向吊落装置相连接的监控装置，反向吊落装置包括至少两个结构相同且沿简支箱梁的纵向方向呈间距布设的反向吊落机构，反向吊落机构包括反吊梁、反力架、加载梁和液压千斤顶，反吊梁、简支箱梁、加载梁和反力架通过吊杆连接；该方法包括：一、反力架、液压千斤顶和加载梁的安装与调整；二、吊杆和反吊梁的安装；三、砂筒和钢管柱的拆除；四、贝雷梁支架的下落。本发明结构简单，能够提高贝雷梁支架下落过程中的水平度，能够提高贝雷梁支架下落的速度和安全性，能够缩短施工工期，节约施工成本。
