摘要
烟台来福士20 000t固定桥式起重机的横梁是目前世界上跨度最大、起重量最大、起升高度最高的起重机钢梁。施工中采用"预留吊装凹槽、地面整体组装、液压同步提升、液压滑移就位"的施工工艺使钢梁吊装成功。在总结施工难点的基础上,介绍了基座设计、基座施工、整体组装、液压提升、滑移就位、计算机同步控制技术及钢梁稳定保证措施。
The 20 thousand tons fixed bridge crane girder in Yantai Ruffles Offshore Co.,Ltd.owns the largest span,the biggest hoisting weight and the highest hoisting height over the world nowadays.In the construction,it takes several technologies to make sure hoisting successful,such as reserving the hoisting grooves,integral erection on the ground,hydraulic synchronizing hoisting and hydraulic slipping in position.Based on the construction difficulties,this paper introduce base design and construction,entire assembling,hydraulic hoisting,slipping and positioning,synchronization controlling with computer and stability ensuring measures for the steel girder.
