Cable tower top line passing tool for suspension bridge steel beam hoisting and construction method of cable tower top line passing tool
The invention discloses a cable tower top line passing tool for suspension bridge steel beam hoisting and a construction method of the cable tower top line passing tool, and belongs to the technical field of suspension bridge construction traction equipment.The cable tower top line passing tool comprises a first cable saddle, a second cable saddle and a third cable saddle; the first cable saddle, the second cable saddle and the third cable saddle are correspondingly installed on the top cross beam and are sequentially and evenly arranged in the direction from the side span to the middle span towards the cable bent tower, the first cable saddle and the third cable saddle are symmetrically arranged relative to the second cable saddle, and the second cable saddle is higher than the first cable saddle and the third cable saddle. Crisscross reinforcing inclined struts are fixedly connected between the first cable saddle and the second cable saddle and between the second cable saddle and the third cable saddle; and the three cable saddles are provided with a traction cable passing wheel, a bearing cable passing wheel and a hoisting traction cable passing wheel. According to the cable tower top line passing tool for hoisting the steel beam, the bearing cable, the traction cable and the hoisting traction cable are integrated on one device, the layout is reasonable, the structure is more compact, the cost is lower, and after the supporting stability of the whole device is better, the problem of large deformation of the bearing cable is avoided.
本发明公开了一种悬索桥钢梁吊装用索塔顶过线工装及其施工方法，属于悬索桥施工牵引设备技术领域，包括第一索鞍、第二索鞍和第三索鞍，第一索鞍、第二索鞍和第三索鞍对应安装在顶部横梁上且朝向索塔从边跨到中跨方向依次均匀布置，其中第一索鞍与第三索鞍相对第二索鞍对称布置，且第二索鞍高于第一索鞍和第三索鞍，第一索鞍与第二索鞍之间和第二索鞍与第三索鞍之间均固定连接有十字交叉的加固斜撑，三个索鞍设置有牵引索过轮、承重索过轮和起重牵引索过轮。本发明吊装钢梁用的索塔顶部过线工装，将承重索、牵引索和起重牵引索集成在一个设备上，布局合理，结构更紧凑，成本更低，而且整个设备支撑稳定性更好后，避免了承重索的变形大问题。
