Abstract:The handling device of electrolytic cell cover plate is an auxiliary production device which is installed on the aluminum electrolytic multi-function crane. In this paper, the importance of the design and research of the loading and unloading device is described. The research status at home and abrguoneiwai oad and the structure and shape of the groove cover plate is introduced. Based on a kind of structure of groove cover and considering the shape of other groove cover, the design scheme of the device is introduced. The layout form and structure composition of the device are described in detail, and the functions and characteristics of each component are analyzed and discussed. In this paper, the working principle and working process of the loading and unloading device of electrolytic cell cover plate are described in detail. The design and calculation of the key part of the supporting spring in the fixture ensure its strength, stability and function.
