The invention discloses a jacking device and method for a large component of a stadium, and belongs to the technical field of jacking equipment and methods. The jacking device comprises a movable base, a folding lifting rod and a top plate. The movable base is movably connected with the top plate through the folding lifting rod, a first sliding block is slidably installed on the movable base, andthe first sliding block is hinged to the movable end of one side of the lower end of the folding lifting rod. Positioning tooth blocks are arranged on the two sides of the first sliding block, a row of positioning racks parallel to the moving direction of the first sliding block are correspondingly arranged below each positioning tooth block, the positioning tooth blocks are connected with a hydraulic driving mechanism, and the hydraulic driving mechanism is used for driving the positioning tooth blocks to move up and down. By the adoption of the jacking device, the phenomenon that a jacking plate ascends and descends freely due to failure of a hydraulic device can be effectively avoided, potential safety hazards are reduced, and the jacking device is good in stability and reliable to use.
本发明公开了一种场馆大型构件用顶升装置及顶升方法,属于顶升设备及方法技术领域。该顶升装置包括移动底座、折叠升降杆和顶板,移动底座与顶板之间通过折叠升降杆活动相连,所述移动底座上可滑动安装有第一滑块,第一滑块与折叠升降杆下端一侧的活动端铰接相连;所述第一滑块两侧设有定位齿块,定位齿块下方分别对应设有一排与第一滑块运动方向相平行的定位齿条,且定位齿块与液压驱动机构相连,该液压驱动机构用于驱动定位齿块上下移动。采用本发明的顶升装置能够有效避免了液压装置失效使顶升板自由升降的现象,降低了安全隐患,其稳定性较好,使用可靠。
