The invention relates to the technical field of shipbuilding, in particular to a chain block welding-free lifting lug which comprises a welding-free lifting lug body and an upper-layer platform structure, the welding-free lifting lug body is installed below the upper-layer platform structure and comprises a clamping plate A and a clamping plate B, and the clamping plate A is connected with the clamping plate B; a shackle hole used for locking the clamping plate A and the clamping plate B is formed in the connecting position of the clamping plate A and the clamping plate B, a shackle can be inserted into the shackle hole, a chain block connected with the shackle is arranged in the shackle, and a locking piece used for locking the clamping plate A and the clamping plate B is further arranged in the chain block. Compared with the prior art, through the arrangement of the welding-free lifting lug body, a large number of lug plates are prevented from being burnt on site, damage to paint is also prevented, waste of a large number of manpower and material resources is avoided, and follow-up projects that the lifting lug is restored to the original shape due to burning and the like are avoided.
本发明涉及造船技术领域,具体为一种手拉葫芦免焊吊耳,包括免焊吊耳本体与上层平台结构,所述免焊吊耳本体安装在上层平台结构的下方,所述免焊吊耳本体包括卡板A和卡板B,所述卡板A和卡板B相连,所述卡板A和卡板B的连接处设有用于锁死卡板A和卡板B的卸扣孔且该卸扣孔中可插入卸扣,所述卸扣中设有与卸扣相连的手拉葫芦,所述手拉葫芦中还设有用于对卡板A和卡板B进行锁紧的锁紧件。同现有技术相比,通过设置的免焊吊耳本体,避免现场烧大量的耳板,也防止对油漆造成破坏,且避免出现浪费大量的人力物力,以及避免了因烧吊耳等恢复原状等后续工程。
