The invention provides a jacking device, and relates to the field of large-span space structure construction. The jacking device comprises a supporting frame, a moving frame and a translation structure, the supporting frame is connected with the moving frame through the translation structure, the translation structure comprises a plurality of longitudinal sliding rails and a plurality of transverse sliding rails which are arranged in a staggered mode, the longitudinal sliding rails and the transverse sliding rails are slidably connected with the top end of the supporting frame, and the bottom end of the supporting frame is in one-to-one sliding fit with the longitudinal sliding rails through longitudinal sliding blocks; the bottom end of the supporting frame is in one-to-one sliding fit with the transverse sliding rails through transverse sliding blocks, so that the longitudinal sliding rails and the transverse sliding rails support the moving frame at the same time, and the top end of the supporting frame is rotationally connected with a push-pull element abutting against the moving frame. Aiming at the problem that jacking equipment is difficult to meet the translation and jacking requirements during large-span space structure construction at present, a segmented structure is adopted, so that a movable frame can translate relative to a supporting frame to change the jacking position, the movable frame and the supporting frame keep stable contact, and the height and position adjusting requirements in the external structure jacking process are met.
本发明提供一种顶升装置,涉及大跨空间结构施工领域;包括支撑架、移动架和平动结构,支撑架通过平动结构连接移动架,平动结构包括交错布置的多条纵向滑轨和多条横向滑轨,各纵向滑轨和各横向滑轨均滑动连接支撑架顶端,支撑架底端通过纵向滑块与纵向滑轨一一滑动配合,支撑架底端通过横向滑块与横向滑轨一一滑动配合,使纵向滑轨和横向滑轨同时支撑移动架,支撑架顶端转动连接有抵接移动架的推拉元件;针对目前大跨空间结构施工时顶升设备难以满足平动和顶升需求的问题,采用分段结构,使得移动架能够相对于支撑架平动以改变顶升位置,移动架与支撑架之间保持稳定接触,满足顶升外部结构过程中的高度和位置调节需求。
