Construction assembly method of high-speed magnetic levitation bridge large-displacement telescopic device
The invention discloses a construction assembly method of a high-speed magnetic levitation bridge large-displacement telescopic device, which is divided into a factory assembly stage and a field assembly stage, so that a problem of pre-pressure installation of a spring system is solved through temporary construction measures such as a longitudinal beam temporary lengthening section, a longitudinaltemporary fixing steel bar in a longitudinal connecting spring and the like. The system solves the problem of rapid and effective installation of a longitudinal limiting system, a connecting rod system and a spring system in a limited installation operation space. By arranging the rear construction section on the right side, the problem that a longitudinal beam of a large-displacement telescopicdevice extends into a right bridge opening position and is inconvenient to install is solved. Accurate adjustment of the rail elevation and the plane position in the installation period is achieved through multiple height adjusting base plates, quadrilateral holes with round chamfers formed in a fastener system and the like.
本发明公开了高速磁浮桥梁大位移伸缩装置的施工装配方法，分为工厂组装阶段和现场组装阶段，通过纵梁临时接长段、纵向连接弹簧内的纵向临时固定钢棒等临时构造措施，解决了弹簧系统有预压力安装问题；系统解决了纵向限位系统、连杆系统、弹簧系统三个系统在有限安装操作空间下的快速有效安装问题；通过在右侧设置后施工段的方法解决了大位移伸缩装置的纵梁伸入右侧桥梁开孔位置、安装不便的问题；通过多重调高垫板和在扣件系统设置带圆倒角的四边形孔等解决了安装期间的轨道高程及平面位置精确调整。
