Large-span dome structure spiral lifting system and method

The invention discloses a large-span dome structure spiral lifting system and method, and relates to the field of overall lifting of buildings, bridges and large-span equipment. The large-span dome structure spiral lifting system comprises a plurality of lifting devices, one ends of two adjacent lifting devices are close to each other or overlapped in the length direction of a truss structure and staggered by a certain distance in the width direction of the truss structure, and thus a bent and upward extending structure is formed. A propelling device comprises two fixing platforms, a one-way slope guide rail, a propelling sliding block and a hydraulic propelling machine. According to the scheme, the safety of a large-span dome structure in the lifting process can be guaranteed, and the height limitation on existing traditional lifting can be overcome. 本发明公开了一种大跨度穹顶结构螺旋提升系统及方法，涉及建筑、桥梁及大跨度设备的整体提升领域，其包括多个提升装置，相邻的两提升装置的一端沿所述桁架结构长度方向接近或重叠而沿所述桁架结构宽度方向错开一定距离，形成弯折向上延伸的结构；所述推进装置包括：两固定平台，单向斜坡导轨，推进滑块以及液压推进机。该方案既能解决大跨度穹顶
