BIN YUHUA / WEI FUTANG / DOU YONGZHI / WEI JIE / XIONG JIAWEN

The invention discloses a rapid installation method of a stay cable, belongs to the technical field of stay cable installation, and solves the technical problems of large occupied field area and low efficiency in the existing stay cable installation process. The method comprises the steps that a cable releasing disc, a discharging cutting platform, a disc winding device, a cable releasing frame, a lifting device, a movable construction platform and a high tower cable penetrating machine are prepared and arranged in the early stage, and a standard cable is manufactured; the standard cable is installed on a high tower cable penetrating machine; circularly blanking according to the length of the standard cable; manufacturing a finished product standard cable; loading the finished standard cable into a cable releasing frame; and the cable releasing frame is transported to the position to be connected, and then cable penetrating is conducted till the whole stay cable is installed. Discharging is conducted through the reel winding device to obtain a coiled standard cable, and the site area occupied in the discharging process can be greatly reduced; in the circulating discharging process, finished standard cables can be manufactured or loaded into a cable releasing frame or penetrated at the same time, multiple procedures can be carried out at the same time, and the installation efficiency is greatly improved.

本发明公开了一种斜拉索的快速安装方法，属于斜拉索安装技术领域，解决现有斜拉索安装过程占用场地面积大、效率低的技术问题。方法包括：前期准备布置好放索盘、下料切割平台、绕盘器、放索架、提升装置、移动施工平台、高塔穿索机、制做标准索；标准索安装到高塔穿索机；标准索的长度循环下料；制做成品标准索；成品标准索装入放索架；将放索架运输到待连接位置后进行穿索，直到将整个斜拉索安装好。本发明通过绕盘器进行下料得到成盘的标准索，可以大大减少下料过程占用的场地面积；在循环下料过程，可以同时进行制做成品标准索或成品标准索装入放索架或穿索，多下工序可以同时进行，大大提高了安装效率。
