The invention discloses a detachable lifting lug mechanism for a shield cutter head and a lifting method of the detachable lifting lug mechanism. The problem that in the prior art, a cutter head lifting device is inflexible to use and poor in cutter head integration is solved. The lifting lug mechanism comprises a main lifting lug for vertical lifting and an auxiliary lifting lug for turnover lifting, wherein the main lifting lug and the auxiliary lifting lug are detachably arranged on the peripheral surface of a cutter head. The detachable lifting lug can meet the lifting operation requirement of the cutter head, welding, welding flaw detection, planing and polishing work is omitted, the working efficiency is improved, the labor intensity of workers is relieved, the construction cost is reduced, and the detachable lifting lug is good in integration with the cutter head and convenient to disassemble and assemble.
