The invention belongs to the technical field of thin-wall annular part assembling, and discloses a hoisting auxiliary device. The supporting assembly is arranged in a ring of the annular piece and comprises a main beam and a supporting module, the supporting module comprises a rotating disc and at least three supporting assemblies, and the rotating disc is rotationally connected to the main beam; the supporting assembly comprises supporting legs and pull rods, the supporting legs are slidably connected to the guide parts of the main beams, and the two ends of the pull rods are hinged to the supporting legs and the rotating discs correspondingly; under the joint constraint of the guide part and the pull rod, when the rotary disc is rotated in the first direction, the supporting legs extend outwards along the guide part along with the pull rod so as to be fixed to the annular piece, and when the rotary disc is rotated in the second direction, the supporting legs retract inwards along the guide part along with the pull rod so as to be separated from the annular piece. The lifting auxiliary device has universality and is convenient to disassemble and assemble, so that the lifting efficiency is improved.

    本发明属于薄壁环状零件组装技术领域,公开了一种起吊辅助装置。其设置于环状件的环内,包括主梁和支撑模组,支撑模组包括转盘和至少三组支撑组件,转盘转动连接于主梁;支撑组件包括支撑腿和拉杆,支撑腿滑动连接于主梁的导向部,拉杆的两端分别铰接于支撑腿和转盘;支撑腿在导向部和拉杆的共同约束下,当向第一方向转动转盘时,支撑腿随拉杆沿导向部向外伸出以与环状件相固定,当向第二方向转动转盘时,支撑腿随拉杆沿导向部向内回缩以与环状件相分离。本发明的起吊辅助装置,具有通用性,便于拆装,进而提高了起吊效率。
