A circular hole component lifting clamp comprises a lifting ring, a rotary connecting seat, a conical lifting iron core, an expansion cylinder and a locking adjusting component, the lifting ring is connected with the upper portion of the rotary connecting seat, and the lower portion of the rotary connecting seat is connected with a screw at the top of the conical lifting iron core. The locking adjusting component is connected to the portion, below the rotary connecting base, of the screw rod, the outer wall and the inner wall of the expansion cylinder are smooth surfaces, the outer wall is of a cylinder structure, the inner wall is of a conical cylinder structure, and a conical column of the conical lifting iron core is connected into the expansion cylinder in a matched mode; the locking adjusting component abuts against the top of the expansion cylinder. According to the circular hole part lifting clamp, due to the fact that the outer wall of the expansion cylinder and the center hole of the circular hole part are matched in a strip mode, the mutual contact area is large, and therefore the center hole of the circular hole part cannot be scratched; and when rotating force exists on the lifting rope, the rotating force cannot be transmitted to the circular hole part.
一种圆孔部件起吊夹具,包括吊环、旋转连接座、锥形起吊铁芯、膨胀筒和锁紧调节部件,其中所述吊环与所述旋转连接座的上部连接,所述旋转连接座的下部与所述锥形起吊铁芯顶部的螺杆连接,所述锁紧调节部件连接在所述旋转连接座下方的螺杆上,所述膨胀筒的外壁和内壁均为光滑面,其中外壁为圆筒结构,内壁为锥筒结构,并且所述锥形起吊铁芯的锥形柱适配地连接在所述膨胀筒内;所述锁紧调节部件抵接在所述膨胀筒的顶部。本发明提供的一种圆孔部件起吊夹具,由于膨胀筒的外壁与圆孔部件的中心孔采用的条带式配合,相互接触面积大,从而不会对圆孔部件的中心孔带来划伤;当起吊绳上具有转动力时,不会传递到圆孔部件上。
