The invention provides a rotary tower inner support climbing tower crane and a construction method thereof, the crane comprises a load-bearing system, the load-bearing system comprises two telescopic load-bearing beams, a load-bearing plate is welded on the two load-bearing beams, and a horizontal rotation system, a load-bearing system upper support, a truss beam and a hoisting system are sequentially arranged on the load-bearing system; during construction, the two bearing beams of the bearing system are supported on corbels in the cable tower, the cable tower precast blocks are hoisted through the hoisting system, and the angle of the hoisting system is adjusted through the horizontal rotating system. And after one section of the cable bent tower is installed, a bracket is installed on the inner wall, the crane is integrally jacked by the height of one section through the jack and then is supported on the bracket in the cable bent tower again, and circulation construction is conducted. The crane is small in size, high in hoisting capacity, high in construction efficiency and low in cost, a wall-attached structure does not need to be arranged, and ground space is not occupied.
本发明提供一种回转式塔内支撑爬塔吊机及其施工方法,吊机包括承重系统,所述承重系统包括两个伸缩式承重梁,两承重梁上焊接承重板,承重系统上依次设置平转系统、承重系统上支架、桁架梁和起吊系统;施工时,承重系统的两承重梁支撑在索塔内部牛腿上,通过起吊系统起吊索塔预制块,通过平转系统调整起吊系统的角度。索塔一个节段安装完成后,内壁安装牛腿,通过千斤顶将吊机整体顶升一个节段高度后重新支撑在索塔内牛腿上,循环施工。本发明吊机体积小,吊重能力强,不用设置附墙结构,不占用地面空间,施工效率高,成本低。
