The invention relates to a special lifting appliance suitable for a transformer shell. The special lifting appliance comprises a lifting lug unit, a lifting beam, a left buckling unit, a left inserting unit, a right buckling unit and a right inserting unit. The lifting lug unit is detachably fixed on the lifting beam. The left buckling unit and the right buckling unit are both fixed to the lifting beam and are opposite in the left-right direction so as to be used for buckling the left free edge and the right free edge on the transformer shell respectively. The left inserting unit and the right inserting unit are fixed to the left buckling unit and the right buckling unit in a one-to-one correspondence mode respectively, and the left inserting unit and the right inserting unit are opposite in the left-right direction so as to be used for inserting and limiting the left limiting part and the right limiting part on the transformer shell respectively. Therefore, on one hand, the overturning phenomenon of the transformer shell in the lifting process is prevented, and time and labor are saved in the whole lifting process; and on the other hand, the phenomenon that the transformer shell body is damaged by clamping or torn is completely eradicated.
本发明涉及适用于变压器壳体的专用吊具,包括吊耳单元、吊梁、左置卡扣单元、左置插入单元、右置卡扣单元以及右置插入单元。吊耳单元可拆卸地固定于吊梁上。左置卡扣单元、右置卡扣单元均与吊梁相固定,且沿着左右方向相对位置,以分别用来实现对变压器壳体上左置自由边、右置自由边的卡扣。左置插入单元、右置插入单元分别一一相对应地实现与左置卡扣单元、右置卡扣单元的固定,且沿着左右方向相对位置,以分别用来实现对变压器壳体上左置限位部、右置限位部的插入限位。这样一来,一方面,防止了变压器壳体在吊装进程中发生“倾覆”现象,整个吊装过程省时、省力;另一方面,还杜绝了变压器壳体本体被“夹伤”或“被撕裂”现象的发生。
