The eccentric lifting appliance for lifting the upper structure of the aluminum electrolysis cell comprises a lifting appliance body, a lifting hole is formed in the top of the lifting appliance body, horizontal friction plates are installed on the positions, on the two sides of the lifting hole, of the lifting appliance body through installation mechanisms, and vertical abutting plates are symmetrically installed on the two sides of the lifting hole through driving mechanisms. The driving mechanism is arranged to drive the two abutting plates to oppositely move in the length direction of the lifting appliance body, so that the rubber plates on the two abutting plates are both attached to the surface of the lifting hook, and the situation that the lifting appliance body slips and rotates on the surface of the lifting hook in the subsequent lifting process is avoided. Moreover, the friction plate on the lifting appliance body is in contact with the surface of the lifting equipment, and the friction groove in the friction plate greatly increases the friction force between the lifting appliance body and the lifting equipment, so that the cross beam of the lifting appliance body is prevented from deviating on the surface of the lifting equipment, the safety and reliability in the lifting process are ensured, and the practicability is high.
本发明公开了一种起吊铝电解槽上部结构用偏心吊具,包括吊具本体,吊具本体顶部设有吊装孔,吊装孔两侧的吊具本体上通过安装机构安装有水平的摩擦板,吊装孔两侧通过驱动机构对称安装有竖直的抵触板。设置驱动机构分别驱动两个抵触板沿吊具本体的长度方向相向移动,使得两个抵触板上的橡胶板均贴合于起吊钩表面,避免后续吊运过程中,吊具本体在起吊钩的表面打滑转动。而且,吊具本体上的摩擦板与起吊设备表面相接触,摩擦板上的摩擦槽大大增加了吊具本体与起吊设备之间的摩擦力,避免吊具本体的横梁在起吊设备表面发生偏移,保障起吊过程安全可靠,实用性强。
