本发明提供一种钢衬里底板及截锥体模块化吊装装置及吊装方法,包括吊机和吊装桁架,吊装桁架顶端通过第一吊索吊装在吊机上,底端通过第二吊索对底板及截锥体模块吊装;吊装桁架包括外桁架、内桁架、核心筒桁架和辐射桁架,内桁架均匀分布在外桁架内侧,形成同心圆环结构,核心筒桁架位于圆心位置;辐射桁架径向分布,与外桁架、内桁架和核心筒桁架同时连接,形成一体化结构。本发明吊装桁架通过索具、一字钢、工字钢与截锥体、底板模块吊耳连接,通过吊索与吊机吊钩连接,通过吊机吊至反应堆厂房完成就位,本方法提高了安装、焊接质量,降低安全风险,改善了现场焊接条件,提高了劳动效率,节约工期50天,创造了较大的经济效益和社会效益。

    The invention provides a modularized hoisting device and hoisting method for a steel lining bottom plate and a truncated cone. The modularized hoisting device comprises a crane and a hoisting truss, the top end of the hoisting truss is hoisted on the crane through a first sling, and the bottom end of the hoisting truss is used for hoisting a bottom plate and a truncated cone module through a second sling; the hoisting truss comprises an outer truss, inner trusses, a core tube truss and radiation trusses, the inner trusses are evenly distributed on the inner side of the outer truss to form a concentric circular ring structure, and the core tube truss is located at the circle center position; the radiation trusses are distributed in the radial direction and connected with the outer truss, the inner truss and the core tube truss at the same time to form an integrated structure. The hoisting truss is connected with the truncated cone and the bottom plate module lifting lug through the rigging, the straight steel and the I-shaped steel, is connected with the lifting hook of the crane through the sling, and is hoisted to the reactor building through the crane to be completed in place, the mounting and welding quality is improved, the safety risk is reduced, the field welding condition is improved, the labor efficiency is improved, and the construction period is saved by 50 days; and great economic benefits and social benefits are created.
