A heightening seat is fixed at the bottom of a second mast, a transition flange is arranged between a second mast flange and a hydraulic cylinder flange, the second mast flange and the hydraulic cylinder flange are fixed into a whole through bolts, and the transition flange is formed by butting two semicircular flanges. A locking component is reinforced between the hydraulic cylinder and the hydraulic rod; lifting lugs are fixed on two sides of a reinforcing structure at the bottom of the second mast; lifting rings are arranged on two sides of a transition flange; a chain block sequentially penetrates through the lifting lugs and the lifting rings, so that a bolt between the transition flange and a second mast flange is detached, and a cylinder body of the hydraulic cylinder is separated from the second mast; and then the transition flange is separated, the chain block is tensioned, and the two semicircles of the transition flange are detached from the two sides of the hydraulic cylinder correspondingly and hoisted to the ground. Under the condition that the stress form of the hydraulic cylinder is not changed, the large hydraulic cylinder can be independently disassembled and assembled under the condition that a large structure is not disassembled, and the maintenance operation of the hydraulic cylinder is carried out.
一种带有可拆除液压缸构件的风帆及拆除方法,在第二桅杆底部固定增高座,二桅法兰与液压缸法兰之间设置有过渡法兰,通过螺栓固定成一体,过渡法兰由两个半圆形法兰对接形成。增高座对第二桅杆进行支撑,液压缸与液压杆之间加固锁紧构件,在第二桅杆底部的加强结构的两侧固定吊耳,过渡法兰两侧设置吊环,手拉葫芦依次穿过吊耳、吊环,将过渡法兰与二桅法兰之间的螺栓拆卸下来,液压缸缸体与第二桅杆分离,再将过渡法兰分离,拉紧手拉葫芦,过渡法兰的两个半圆分别自液压缸两侧拆卸并吊运至地面。本发明在不改变液压缸的受力形式情况下,让该大型液压缸满足不拆卸大型结构的条件下,可单独拆卸和安装,进行液压缸的维护作业。
