The invention relates to the technical fields of lifting and transferring of annular workpieces, in particular to a lifting appliance for rapidly lifting annular workpieces and a lifting method. The lifting appliance comprises an outer lifting appliance set, a movable supporting mechanism and an inner lifting appliance set, and the lifting method comprises the steps of stacking, lifting applianceplacement, bearing positioning, lifting and reset separation. Through the arrangement of switching between the outer lifting appliance set and the inner lifting appliance set, the movable supporting mechanism is controlled to expand and contract, so that the lifting appliance can be quickly separated from an annular workpiece after the annular workpiece is lifted, the situation that the lifting appliance and the annular workpiece are synchronously heated is avoided, and the technical problem that a traditional lifting appliance cannot be quickly separated from the annular workpiece is solved.

    本发明涉及环形工件的起吊转移技术领域,具体为一种环形工件快速吊装吊具及吊运方法,吊具包括外吊具组、移动支撑机构及内吊具组,吊运方法包括堆垛、吊具置入、承载定位、吊运及复位脱离步骤,通过设置外吊具组与内吊具组的切换,实现对移动支撑机构的扩张与收缩的操控,使得吊具在对环形工件完成吊运后,可以快速的脱离环形工件,避免了吊具与环形工件同步进行加热的情况,解决了传统吊具无法从环形工件快速脱离的技术问题。
