The invention relates to the technical field of steel net rack lifting systems, in particular to a synchronous integral lifting system for a double-curved-surface cantilever steel net rack and a construction method.The synchronous integral lifting system comprises a stand column, a weight reduction assembly is arranged at the top of the stand column and comprises a fixed support, a first pulley, a second pulley and a movable pulley, and the fixed support is arranged at the top of the stand column; according to the double-curved-surface overhanging steel net rack, the connected parts of the double-curved-surface overhanging steel net rack form a movable pulley set, the tensile force borne by the steel rope can be effectively reduced, and compared with the prior art, the double-curved-surface overhanging steel net rack has the advantages that the construction cost is reduced, and the construction efficiency is improved. According to the double-curved-surface cantilever steel net rack lifting device, the single center hole type hydraulic jack can load larger weight and is wider in application range, lifting of the double-curved-surface cantilever steel net rack can be completed by installing the center hole type hydraulic jack on a transport vehicle, the center hole type hydraulic jack does not need to be repeatedly installed and dismantled, the construction difficulty can be effectively lowered, the construction process is simplified, and the construction efficiency is improved.
本发明涉及钢网架提升系统技术领域,具体是双曲面悬挑钢网架同步整体提升系统和施工方法,包括有立柱,立柱的顶部设置有减重组件,减重组件包括有固定支架、第一滑轮、第二滑轮以及移动滑轮,固定支架设置在立柱的顶部,钢绳依次绕过移动滑轮、第一滑轮以及第二滑轮,立柱的旁侧设置有地面提升组件,本发明中,将双曲面悬挑钢网架相连接的部分组成一个动滑轮组,可有效降低钢绳所受到的拉力,相较于现有技术,单个穿心式液压千斤顶能够负载的重量更大,适用范围更广,将穿心式液压千斤顶安装在运输车上,即可完成对双曲面悬挑钢网架的提升,无需反复对穿心式液压千斤顶进行安装与拆除,可有效降低施工难度,简化施工过程,提高施工效率。
