The invention discloses an adjustable hanging point lifting appliance and a lifting method, and the adjustable hanging point lifting appliance comprises a cross beam, a shaft sleeve, a long plate, a shaft, a lifting ring, a check ring, a fulcrum shaft, a bearing check ring, a roller assembly, a clamping seat, a clamping block, a screw rod, an adapter plate, a rocker arm, a connecting disc, a connecting pin, a movable lifting rod, a pin and a bearing, and the lifting ring can slide on the cross beam through the roller assembly so as to generate horizontal displacement relative to the movable lifting rod. Before hoisting, the rocker arm is rotated to drive the hoisting ring to displace relative to the movable hoisting rod, so that the hoisting ring is moved to the mass center position of the part, and hoisting balance is achieved. The lifting device can be used for lifting parts with lifting points not located at the mass centers of the lifted parts, adjustment is convenient and rapid, and the lifting efficiency is improved.
本发明公开了一种可调挂点吊具及吊装方法,可调挂点吊具包括横梁、轴套、长板、轴、吊环、挡圈、支轴、轴承挡圈、滚轮组件、卡座、卡块、螺杆、转接板、摇臂、连接盘、连接销、活动吊杆、销钉和轴承,吊环可以通过滚轮组件在横梁上滑动从而实现相对活动吊杆产生水平位移。起吊前,通过旋转摇臂驱动吊环相对活动吊杆产生位移,进而将吊环移动到零件的质心位置,达到起吊平衡。本发明可用于吊点不在被吊零件质心处的零件吊装,调整方便迅速,提高了吊装效率。
