high-low tower cable-stayed bridge closure center line deviation adjusting device and method
The invention provides a high-low tower cable-stayed bridge closure center line deviation adjusting device which comprises two traction pipes, two traction ropes and two traction power devices, the middles of the two traction pipes are hinged to form an X-shaped structure, and in the X-shaped structure, the traction pipe end on one side is fixed to two steel box girders; one end of each of the twotraction ropes is wound and fixed with the traction pipe end on the other side in the X-shaped structure; the two traction power devices are connected with the other end of each of the two traction ropes, located on the outer side of the X-shaped structure and fixed to the two steel box girders, and the traction power devices pull the two steel box girders through the traction ropes so as to be aligned with the center lines of the two steel box girders. The invention further correspondingly provides an implementation method of the device. Deviation rectification is conducted after the centerlines of the two sides of the closure opening deviate, the traction devices at the two ends are started at the same time till the center lines of the steel box girders at the two cantilever ends of the closure opening are aligned, and after traction alignment, steel plates are welded to the free ends of the stiff frameworks on the two sides of the closure opening to complete framework overall locking.
本发明提供了一种高低塔斜拉桥合拢口中心线偏差调整的装置，包括包括两根牵引管、两牵引绳和两牵引动力装置，两根牵引管在中部铰接形成X形结构，X形结构中，其中一侧的牵引管端分别固定在两钢箱梁上；两牵引绳的一端分别与X形结构中另一侧的牵引管端缠绕固定；两牵引动力装置分别与两牵引绳的另一端连接，且两牵引动力装置位于X形结构外侧并分别固定在两钢箱梁上，牵引动力装置通过牵引绳拉动两钢箱梁以对齐两钢箱梁的中心线。且还相应提供了该装置实施方法。在合拢口两侧中心线出现偏移后进行纠偏，同时启动两端牵引设备，直至合拢口两悬臂端钢箱梁中心线完成对齐，当牵引对齐后，合拢口两侧的劲性骨架自由端焊接钢板完成骨架整体锁定。
