The invention provides a large-span net rack jacking horizontal displacement limiting device which comprises a self-adaptive device arranged on a net rack in the circumferential direction, a structural column is arranged in the net rack in a penetrating mode, the self-adaptive device is connected with a roller assembly through a third jack, and the roller assembly is arranged on the side wall of the structural column in a sliding mode. The middle of the net rack is jacked through a bearing support and a first jack, and a limiting rail unit is detachably arranged at the top of the structural column and used for expanding the moving range of the rolling wheel assembly. The net rack jacking device can guarantee high accuracy and stable position in the net rack jacking process, can solve the safety problem when the net rack is separated from the top surface of a structural column, is convenient to mount and dismount, and has good economic benefits.
本发明提供一种大跨度网架顶升水平位移限位装置,包括沿周向设置在网架上的自适应装置,结构柱穿设在网架内,自适应装置通过第三千斤顶连接有滚轮组件,滚轮组件滑设在结构柱的侧壁,网架的中部通过承载支架和第一千斤顶进行顶升,结构柱的顶部可拆卸的设有限位轨道单元,限位轨道单元用于拓展滚轮组件的移动范围。本发明能保证网架顶升过程中精确度高,位置稳定,且能解决脱离结构柱顶面时的安全性问题,安拆方便,具有良好的经济效益。
