Suspension bridge catwalk cable rotating saddle structure assembly
The invention belongs to the technical field of suspension bridge catwalk construction, and particularly relates to a cable rotating saddle structure assembly of a suspension bridge catwalk. The system at least comprises a main cable saddle grating reaction frame, a tower top gantry, a second rotating cable saddle and a suspension bridge catwalk, two pairs of main cable saddle grating reaction frames are arranged on the left and the right; the number of the second rotating cable saddles is four, and the four second rotating cable saddles are symmetrically arranged on the two sides of the suspension bridge catwalk and connected to the gantry column feet of the tower top gantry; the second rotating cable saddle comprises a second rotating cable saddle supporting seat and a second rotating cable saddle body, and the second rotating cable saddle body is connected to a column foot of the tower top gantry through the second rotating cable saddle supporting seat; the device further comprises two first cable rotating saddles. The two first cable rotating saddles are symmetrically arranged on the two sides of the suspension bridge catwalk and connected to the outer sides of the two main cable saddle grating reaction frames correspondingly. Under the condition that the pre-deviation of the main cable saddle is large, the horizontal force difference in operation is overcome, so that the catwalk line shape is consistent with the line shape of the main cable, and the main cable construction is facilitated.
本发明属于悬索桥猫道施工技术领域，具体涉及一种悬索桥猫道转索鞍结构总成。本发明包括至少包括主索鞍格栅反力架、塔顶门架、第二转索鞍和悬索桥猫道；主索鞍格栅反力架左右设置两副；第二转索鞍设置有四个，四个第二转索鞍对称的设置在悬索桥猫道的两侧且连接在塔顶门架的门架柱脚处；第二转索鞍包括第二转索鞍支撑座和第二转索鞍鞍体，第二转索鞍鞍体通过第二转索鞍支撑座连接在塔顶门架的柱脚处；还包括两个第一转索鞍；两个第一转索鞍对称的设置在悬索桥猫道的两侧，且分别连接在两副主索鞍格栅反力架外侧上。本发明在主索鞍预偏量大的情况下，克服了作业中的水平力差，使猫道线形与主缆的线形的一致，便于主缆施工。
