Cable adjusting device and cable adjusting method for catwalk bearing cable of suspension bridge
The invention discloses a cable adjusting device and method for a catwalk bearing cable of a suspension bridge, and the cable adjusting device comprises a fixed frame fixed on a cable tower of the suspension bridge, the fixed frame is provided with an integral cable adjusting sliding frame capable of vertically lifting, and the cable tower is fixedly provided with an integral cable adjusting driving part for driving the integral cable adjusting sliding frame to lift. The catwalk bearing cable is supported on the integral cable adjusting sliding frame; single-cable adjusting driving parts in one-to-one correspondence with the catwalk bearing cables are fixed on the integral cable adjusting sliding frame, the single-cable adjusting driving parts are connected with the corresponding catwalk bearing cables, and the connecting parts of the catwalk bearing cables and the single-cable adjusting driving parts are vertically jacked when the single-cable adjusting driving parts work. Synchronous adjustment or independent adjustment of the middle span and the side span of the catwalk bearing cable can be achieved, linear control over the catwalk bearing cable is more accurate, and the linear adjustment effect and adjustment efficiency of the catwalk bearing cable are improved; the use of a large number of embedded parts and force bearing components is reduced, the construction period is effectively shortened, and the construction cost is effectively reduced.
本发明公开了悬索桥猫道承重索的调索装置及调索方法，其调索装置包括固定在悬索桥的索塔上的固定架，固定架上设有可竖直升降的整体调索滑动架，索塔上固定有驱动整体调索滑动架升降的整体调索驱动件，猫道承重索支撑在整体调索滑动架上；整体调索滑动架上固定有与猫道承重索一一对应的单索调索驱动件，单索调索驱动件与对应的猫道承重索连接，单索调索驱动件工作时将猫道承重索与单索调索驱动件相连接部位竖直顶升。本发明能够实现对猫道承重索中跨、边跨的同步调整或单独调整，对猫道承重索的线形控制更加准确、提高了猫道承重索的线形调整效果和调整效率；本发明减少了大量预埋件和承力构件的使用，有效降低了施工周期和施工成本。
