The invention discloses a tetragonal body turnover holding and clamping lifting appliance which comprises two L-shaped clamping arms. The middles of transverse rods of the two clamping arms are connected with each other through a hinge, lifting lugs are arranged at the ends of the transverse rods of the clamping arms, bearing packs are arranged at the ends of vertical rods of the clamping arms, rotating shafts are installed in the bearing packs, and clamping plates are arranged at one ends of the clamping arm inner sides of the rotating shafts. The clamping plates are connected with the rotating shafts through hinges, a winch is arranged on one of the clamping arm vertical rod, and the winch is connected with the end of the other clamping arm transverse rod through a steel wire rope. The opening size of the clamping arms can be adjusted through the winch, the lifting lugs are lifted and installed through a cantilever crane, a crown block and the like, meanwhile, the winch is loosened,the clamping arms can automatically clamp a tetragonal body through the lever principle, the direction of the tetragonal body can be easily adjusted, operation can be conducted by one person, easinessand labor saving are achieved, and meanwhile, damage to the tetragonal body or injury to personnel is avoided.
本发明公开了一种四方体翻转抱夹吊具,抱括两个“L”型夹臂,两个所述夹臂横杆中部通过铰链相互连接,所述夹臂横杆端部设有吊耳,所述夹臂竖杆端部设有轴承组,所述轴承组内安装有转轴,所述转轴夹臂内侧一端设有夹板,所述夹板通过铰链与转轴连接,其中一个夹臂竖杆上设有绞盘,所述绞盘通过钢丝绳与另一夹臂横杆端部连接。通过绞盘可以调整夹臂开口尺寸,通过悬臂吊、天车等对吊耳进行吊装,同时松开绞盘,夹臂通过杠杆原理可以自动对四方体进行夹紧,这时可轻松对四方体方向进行调整,可以单人进行操作,轻松省力,同时避免了四方体的损坏或对人员产生伤害。
