The invention discloses a centering device for electric permanent magnet hoisting. The centering device for electric permanent magnet hoisting comprises a machine base, clamping arms, elastic return pieces and clamping arm auxiliary pieces, wherein one ends of the clamping arms are rotationally connected with the machine base, the elastic return pieces are arranged at positions adjacent to the rotating connecting ends between the clamping arms and the machine base, and the elastic return pieces are used for providing inward return force for the clamping arms when the clamping arms are opened under the action of external force. The clamping arms can automatically adjust the relative position between a lifting appliance and a lifted object along with the downward movement of the lifting appliance, balance the stress of four corners, can complete centering before an electric permanent magnet makes contact with the lifted object, and make direct contact with a pipeline on the basis of centering completion, and the electric permanent magnet can make perfect contact; the opening degrees of the clamping arms with elastic structures can be automatically adjusted and adapt to steel pipes inany range; and the mounting structure is simple, and the occupied space is small.

    一种用于电永磁吊装的对中装置,包括:机座、夹臂、弹性复位件以及夹臂辅助件;其中,夹臂一端与机座转动连接,在夹臂与机座转动连接端相邻位置设置弹性复位件,该弹性复位件用于在夹臂在外力作用下张开时给夹臂提供一个向内复位的力;夹臂随着吊具下移能自动进行调节吊具和被起吊物之间的相对位置,平衡四角的受力,可在电永磁铁与被起吊物接触前完成对中,在对中完成的基础上直接与管道接触,电永磁铁能完美接触;弹性结构的夹臂的开度可自动调节,适用任意范围的钢管;安装结构简单,占用空间少。
