Eccentric lifting appliance for lifting upper structure of aluminum electrolysis cell

Abstract

The utility model discloses an eccentric lifting appliance for lifting an upper structure of an aluminum electrolysis cell, which comprises a lifting appliance body, a lifting hole is arranged at the top of the lifting appliance body, horizontal friction plates are mounted on the lifting appliance body on two sides of the lifting hole through a mounting mechanism, and vertical contact plates are symmetrically mounted on two sides of the lifting hole through a driving mechanism. 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.
