The invention provides a turnover lifting appliance. The turnover lifting appliance comprises a lifting unit, a first clamp body, a second clamp body, a first force transmission unit and a second force transmission unit, wherein an upper clamp part is arranged on the first clamp body; the second clamp body comprises a lower clamp part and a connecting part; the lower clamp part is opposite to the upper clamp part; the connecting part is rotationally connected with the first clamp body; the first force transmission unit and the second force transmission unit are arranged between the lifting unit and the first clamp body; when the lifting unit drags the first clamp body through the first force transmission unit, the first clamp body rotates relative to the connecting part in the first direction; and when the lifting unit drags the second clamp body through the second force transmission unit, the first clamp body rotates relative to the connecting part in the second direction. In the process that the first clamp body rotates relative to the connecting part, the upper clamp part and the lower clamp part which are oppositely arranged get close to each other or get away from each other, opening and closing actions are completed, so that a workpiece is grabbed. The whole structure of the turnover lifting appliance is simple and light, and the turnover lifting appliance can be easily transferred by virtue of hoisting equipment such as a travelling crane, so that the turnover lifting appliance can work in a large range.

    本发明提供一种翻转吊具,包括:起吊单元;第一钳体,第一钳体上设有上钳部;第二钳体,包括下钳部和连接部,下钳部与上钳部相对,连接部与第一钳体转动连接;和设置在起吊单元与第一钳体之间的第一传力单元和第二传力单元。起吊单元通过第一传力单元牵引第一钳体时,第一钳体相对于连接部沿第一方向旋转;起吊单元通过第二传力单元牵引第二钳体时,第一钳体相对于连接部沿第二方向旋转。在第一钳体相对于连接部旋转的过程中,相对设置的上钳部和下钳部相互靠拢或者远离,完成张合动作,从而实现对工件的抓取。翻转吊具的整体结构简单轻便,借助行车等起重设备可以轻易地转移位置,从而能够在大范围内作业。
