摘　　要：研究了一种桥梁钢塔浮吊提升转体工艺,即由工厂拼装成整体,船运至施工现场,然后通过大型浮吊转体吊装,最后利用导向及精调位装置进行匹配。分析了转体吊装过程中可能遇到的各种问题,并对应提出了具体的、行之有效的解决措施。对转体吊耳、转动铰、滑移系统以及导向调位装置进行了深入研究,并进行了详细设计,各结构新颖,可拆装性好,对钢塔损伤较小,承载能力强。最后对转体吊装及精确调位过程中钢塔的稳定性进行了系统分析,证明了整个过程安全可行。This paper researches a kind of lifting and swiveling technology to the steel tower with floating crane： it was assembled in the factory,transported to the construction site by vessels,then swiveled and hoisted by a floating crane,matching using guide and refined adjustment device at last. The various kinds of problems occurring in the process are analyzed and the effectively specific solutions are proposed. The further study to swivel lifting lugs,rotating hinge,slip system,guiding and adjustable device is carried out as well as detailed design. The structure is original and removable,which is limited damage to steel tower with high bearing capacity. Finally,systematic analysis of the steel tower stability is conducted,which proves the feasibility and safety of the process.
