摘要：

白莲河抽水蓄能电站金属结构设备安装的最大难点是如何克服现场作业场地狭窄及安装高度大的困难，将位于上库进（出）水口塔体平台以上20m的事故闸门卷扬式启闭机卷筒吊装就位。提出了将1000kN汽车起重机停靠到现有的塔体平台上，在支腿不全部伸出的情况下，利用汽车起重机的极限机械性能，直接在塔体平台上进行卷筒的卸车和吊装的施工方案，快速、经济地完成了吊装任务。

Abstract: In the installation of the metal structure equipment of the Bailianhe Pumpedstorage Power Station, the largest difficult point is how to overcome the difficulties of the straitness of work field and the larger installing height and lift the winding drum of the winchhoist of the emergency gate into its place, which locates 20m above the tower body platform in the inlet (outlet) of the upper reservoir. A construction scheme was put forward, according the scheme, the 1000kN autocrane was stopped on the existing tower body platform; the landing legs was stretched out partly; using the ultimate mechanical property of the autocrane, the winding drum had been unloaded and lifted directly in the tower body platform. The installation task was accomplished quickly and economically. 

Key words: pumped-storage power station, winch-hoist, winding drum, lifting and installing
