The invention relates to the field of clamps, and discloses a special lifting appliance for a concrete prefabricated part. The bottom end of a spring is fixedly connected with a pressing block, the outer surface of the pressing block is slidably connected with the inner wall of a connecting cylinder, the bottom of the pressing block is fixedly connected with a connecting disc, and rotating blocks are symmetrically arranged at the top of the connecting disc; the bottom of the rotating block is fixedly connected with the top of the connecting disc, the top of the rotating block is fixedly connected with a connecting plate, bent plates are symmetrically arranged on the outer surface of the connecting cylinder, the inner walls of the bent plates are fixedly connected with the outer surface of the connecting cylinder, and the ends, away from the connecting cylinder, of the bent plates are fixedly connected with the top of the connecting plate. By arranging the connecting plate and the spring, through cooperation of the connecting plate and the spring, the two sides of the clamping plate mechanism are opened at the same time, and the situation that clamping arms of the clamping plate mechanism are placed on the two sides of a prefabricated slab through workers as before, and clamping injuries are caused under cooperation of a crane is avoided.

    本发明涉及夹具领域,且公开了一种混凝土预制件专用吊具,所述弹簧的底端固定连接有压块,所述压块的外表面与连接筒的内壁滑动连接,所述压块的底部固定连接有连接盘,所述连接盘的顶部对称设置有转块,所述转块的底部与连接盘的顶部固定连接,所述转块的顶部固定连接有连接板,所述连接筒的外表面对称设置有曲板,所述曲板的内壁与连接筒的外表面固定连接,所述曲板远离连接筒的一端与连接板的顶部固定连接,通过设置连接板与弹簧,通过连接板与弹簧的配合,使夹板机构两侧同时张开,避免在将夹板机构的夹臂像原先通过工人将夹臂放置在预制板的两侧,导致在于起重机配合下造成夹伤。
