The invention relates to the technical field of lifting lugs, and discloses a barrel turnover lifting lug which comprises a bottom plate and a main connecting plate, the main connecting plate is fixed to one side of the bottom plate, a first lifting lug plate is arranged on one side of the main connecting plate, a plurality of through holes are formed in the bottom plate, and a main connecting bolt is arranged on the through hole in the middle of the bottom plate; during hoisting, the lifting lug at one end is lifted, so that the rotor sail cylinder body can be overturned and hoisted from a horizontal state to a vertical state, subsequent mounting and fixing of the rotor sail cylinder body are facilitated, and the rotor sail cylinder body is convenient to mount and dismount. Meanwhile, the influence of thermal cutting after welding and hoisting on paint is avoided through bolt connection; and the bolt connection can be reused, so that the manufacturing of the lifting lug is saved.

    本发明涉及吊耳技术领域,公开了筒体翻身吊耳,包括:底板和主连接板,所述底板一侧固定有主连接板,所述主连接板一侧设有第一吊耳板,所述底板内开设有若干通孔,位于所述底板中部的通孔上设有主连接螺栓,位于所述底板两侧的通孔上设有副连接螺栓,所述主连接板两侧设有第一加强板、第二加强板和第三加强板,本发明在吊装时,抬升一端的吊耳,即可将转子帆筒体由水平状态翻转吊装至垂直状态,便于转子帆筒体后续的安装固定,同时通过螺栓连接避免焊接和吊装后的热切割对油漆的影响;而且螺栓连接可以重复使用,节省吊耳的制作。
