The invention relates to the field of lifting appliances, in particular to a large ring component self-locking lifting device which comprises a bearing circular truncated cone. A plurality of locking clamp mechanisms are uniformly distributed and mounted on the bearing circular table, the plurality of locking clamp mechanisms can slide along the radial direction of the bearing circular table, each locking clamp mechanism comprises a clamping bracket, a supporting part for supporting the bottom of the ring component is mounted on the clamping bracket in a hinged manner, and an abutting part for abutting against the outer ring surface of the ring component is mounted on one side of the supporting part; the centering locking mechanism drives the multiple locking clamp mechanisms to slide synchronously, and the centering locking mechanism is in transmission connection with the locking clamp mechanisms. The outer ring face of the ring component is locked through the abutting parts of the locking clamp mechanisms, the bottom of the ring component is supported through the supporting parts, clamping and fixing of the ring component are achieved, and the centering locking mechanism is convenient to use. Damage to the ring component in the hoisting process is reduced, and meanwhile the universality of the device is improved.
本发明涉及吊具领域,具体涉及一种大型环构件自锁定吊装装置,包括:承载圆台;承载圆台上均布安装有多个锁定夹具机构,多个所述锁定夹具机构可沿承载圆台的径向滑动,锁定夹具机构包括夹持支架,所述夹持支架上铰接安装有承托环构件底部的支撑部,所述支撑部的一侧安装有抵靠住环构件外环面的抵靠部;带动多个所述锁定夹具机构同步滑动的对心锁定机构,对心锁定机构与所述锁定夹具机构传动连接,本发明通过锁定夹具机构的抵靠部对环构件的外环面进行锁定,支撑部对环构件的底部进行承托,实现对环构件的夹持固定,减少了吊装时对环构件的损伤,同时提高了装置的通用性。
