HYDRAULIC HEIGHT ADJUSTMENT DEVICE FOR INSTALLING ULTRA-HEAVY STRUCTURE

摘要

The present invention relates to a hydraulic height adjustment device for installing an ultra-heavy structure, which can secure a stable horizontal supporting force against a horizontal load of an upper structure. The present invention comprises: a lower frame installed in a transport vessel and provided with a plurality of insertion portions each having a space with an upper portion opened; and a hydraulic cylinder device which is seated in the insertion portions of the lower frame and regulates the height of an upper structure by vertically expanding and contracting in a state where the upper end of the hydraulic cylinder device supports the upper structure, wherein the insertion portions are provided with a support guide which surrounds the hydraulic cylinder device in an annular shape and is positioned between the inner wall of the insertion portions and the hydraulic cylinder device to provide resistance to tilting of the hydraulic cylinder device.
