Main cable transverse moving system of space cable-shaped suspension bridge and construction method
The invention provides a main cable transverse moving system of a space cable-shaped suspension bridge and a construction method.The system comprises a traction device guide rail, the traction device guide rail is sleeved with a dynamic counter-force frame and a dynamic traction frame of a right traction device and a left traction device, and the dynamic traction frame is fixedly connected with a self-adaptive rotating main cable holding clamp; and a space main cable is arranged in the self-adaptive rotating main cable holding clamp. According to the system, a traction elastic automatic lock and a counter-force elastic automatic lock are arranged in the traction device, and a guide elastic automatic lock is arranged on a guide rail of the traction device, so that a dynamic counter-force frame or a dynamic traction frame of the traction device can be limited, small-displacement pushing can be realized, a main cable can be accurately positioned, and the service life of the main cable is prolonged. And the shape of the spatial main cable can be accurately controlled. According to the construction method, a main cable transverse moving system of the space cable-shaped suspension bridge is adopted, multi-step small-displacement pushing is carried out in main cable transverse moving construction, and it is guaranteed that the space main cable is smoothly formed.
本发明提供了一种空间索形悬索桥的主缆横移系统及施工方法，该系统包括牵引装置导向轨，牵引装置导向轨上套设有右牵引装置和左牵引装置的动态反力架和动态牵引架，动态牵引架与自适应转动主缆抱夹固定连接，自适应转动主缆抱夹内设置有空间主缆。该系统通过在牵引装置中设置牵引弹性自动锁和反力弹性自动锁，在牵引装置导向轨上设置导向弹性自动锁，能够对牵引装置的动态反力架或动态牵引架进行限位，进而能够实现小位移顶推，使得主缆能够精准定位，并能精准控制空间主缆线形。该施工方法通过采用空间索形悬索桥的主缆横移系统，在主缆横移施工进行多步小位移顶推，保证了空间主缆顺利成形。
