The invention discloses a multipurpose lifting appliance for annular components of an aero-engine. The multipurpose lifting appliance comprises a long lifting ring and a plurality of lifting belts; the upper end of each lifting belt is mounted on the long lifting ring; and a hanging lug is mounted at the lower end of each lifting belt, a lifting ring bolt block is mounted on each hanging lug, a plurality of studs with different thread specifications are arranged on each lifting ring bolt block, and a hexagon nut and a spacer sleeve are arranged on each stud. The plurality of lifting belts are arranged on the long lifting ring, and the plurality of studs with different thread specifications are arranged on the lifting ring bolt block at the end of each lifting belt, so that the same lifting appliance can be used for covering the lifting of annular components of the whole machine; and in addition, the lifting belts, the long lifting ring and the hanging lugs are installed in a bow shackle mode, dismounting and mounting are convenient, and quick replacement of the lifting ring bolt blocks is facilitated. The lifting belts are adopted to replace traditional steel wire ropes, and the lifting belts are softer than the steel wire ropes and do not prick hands, so that operators can be protected.
一种航空发动机圆环形零组件多用吊具,包括:长吊环以及多根吊装带;每根吊装带的上端均安装在所述长吊环上;在每根吊装带的下端安装有挂耳,在所述挂耳上安装有吊环螺栓块,在吊环螺栓块上设置有多根具有不同螺纹规格的螺柱,在每根螺柱上设置有六角螺母和挡套。本发明通过在长吊环上设置多根吊装带,并在每根吊装带端的吊环螺栓块设置多根具有不同螺纹规格的螺柱,实现了采用同一吊具即可覆盖整机圆环形零组件的吊装;另外,吊装带与长吊环、挂耳之间采用弓形卸扣的方式安装,拆卸安装方便,便于吊环螺栓块的快速更换。在本发明中,采用吊装带替代传统的钢丝绳,吊装带相对钢丝绳较为柔软,不扎手,有利于保护操作工人。
