The invention relates to a synchronous jacking and replacing device and method for shock insulation supports of an LNG storage tank, and the system comprises a plurality of auxiliary supports which are installed at the bottom of the LNG storage tank at intervals; the top of each auxiliary support is correspondingly provided with one hydraulic jack, and the hydraulic jacks are used for synchronously jacking or descending the LNG storage tank; the hydraulic pump is connected with the plurality of hydraulic jacks through the hydraulic pipelines; a plurality of electromagnetic control valves; and the PLC is electrically connected with the hydraulic pump and the electromagnetic control valve, and controls the action of the plurality of hydraulic jacks. The replacing device is used for synchronous jacking of the LNG storage tank shock insulation support, it can be guaranteed that jacking point positions are synchronously lifted in the synchronous jacking and falling process, and stress and deformation of an original LNG storage tank are not changed.
本发明涉及一种LNG储罐隔震支座同步顶升更换装置和方法,所述系统包括:若干个辅助支座,若干个所述辅助支座间隔安装在所述LNG储罐的底部;若干个液压千斤顶,每个所述辅助支座的顶部对应安装一个所述液压千斤顶,所述液压千斤顶用于将所述LNG储罐同步顶升或降落;液压泵和液压管线,所述液压泵与若干个所述液压千斤顶之间通过所述液压管线连接;若干个电磁控制阀;PLC控制器,所述PLC控制器与所述液压泵和电磁控制阀电连接,并控制若干个所述液压千斤顶动作。所述更换装置用于LNG储罐隔震支座的同步顶升,可以在同步顶升以及回落的过程中保证各顶升点位同步提升,不改变原有LNG储罐的受力和变形。
