The invention discloses a lifting appliance. The lifting appliance comprises two clamp arms, the middle portions of the two clamp arms are hinged, the tail portions of the two clamp arms are hung, and the head portions of the two clamp arms are provided with opposite clamping jaws at intervals. And the middle parts of the two clamp arms are provided with a hinge shaft and a plurality of hinge hole sites for mounting the hinge shaft. According to the lifting appliance, the two clamp arms capable of doing shear type motion and the clamping jaws arranged on the clamp arms can be used for clamping a to-be-lifted workpiece, and the lifting problem of the to-be-lifted workpiece such as an aluminum alloy round cast ingot can be solved. According to the lifting appliance, to-be-lifted workpieces with different sizes and weights can be clamped by adjusting the mounting positions of the hinge shafts in the hinge hole sites, and the larger the weight of the to-be-lifted workpieces is, the larger the clamping degree of the lifting appliance to the to-be-lifted workpieces is, so that the to-be-lifted workpieces are prevented from falling off in the lifting process. Therefore, the lifting appliance provided by the invention is simple in structure and convenient to use, can adapt to the to-be-lifted workpieces of different specifications, and realizes synchronous operation of clamping and lifting.

    本申请公开了一种吊具,包括两个夹钳臂;两个夹钳臂的中部铰接且尾部吊挂,两个夹钳臂的头部设有间隔相向的夹爪;两个夹钳臂的中部设有一个铰接轴和多个可供铰接轴安装的铰接孔位。该吊具可以利用两个可做剪式运动的夹钳臂和设于夹钳臂的夹爪夹持待吊装工件,可解决铝合金圆铸锭等待吊装工件的吊运问题。该吊具通过调整铰接轴在铰接孔位内的安装位置可以实现夹持不同尺寸和重量的待吊装工件,而且待吊装工件的重量越大,该吊具度对待吊装工件的夹紧程度越大,避免待吊装工件在吊运过程中掉落。可见,本申请所提供的吊具结构简单、使用方便,能够适应于不同规格的待吊装工件,实现夹取和吊装的同步操作。
