The invention discloses a quick-detachable support-leg lifting appliance which comprises a lifting ring and a bolt. The lifting ring is connected with the bolt in a fastening way; after the lifting appliance is installed at the end part of a workpiece, the workpiece can be lifted through the lifting appliance; when the lifting appliance arrives at an allocation position, only the lifting ring needs to be pulled through a pull rope so as to drive the bolt until the head part of the bolt is separated from an installation hole of the workpiece, so that the lifting appliance can automatically falloff; furthermore, the working intensity of operating personnel can be reduced, and the efficiency is improved; and meanwhile, in-air operation is not needed for in-air lifting operation, so that thepotential safety hazard is reduced, and the safety accidents are reduced.
本发明公开了一种快速拆卸支腿吊具,包括吊环和插销,吊环和插销紧固连接,将吊具安装在工件端部后,可以直接通过吊具实现工件的吊运,到达调运位置时,只需要通过拉绳拉动吊环带动插销至插销头部脱离工件的安装孔,则吊具会自动脱落;进而可以降低操作人员的工作强度,提高效率,同时对于空中吊运安装也不需要进行空中作业,降低安全隐患,减少安全事故。
