A lifting device for a shell-piercing cylinder

Abstract

This utility model relates to the field of aluminum electrolysis technology, and in particular to a lifting device for a shell-breaking cylinder. It includes a support base, several guide rails, a lifting assembly, and a drive assembly. The guide rails are housed within the support base. The lifting assembly includes a lifting seat connected to the guide rails, and the lifting seat can slide along the guide rails. The drive assembly includes a lead screw and a lead screw nut. The shell-breaking cylinder is connected to the lifting assembly. In this utility model, the lifting seat connects the shell-breaking cylinder and the lead screw nut, resulting in a significant amount of vibration generated by the shell-breaking cylinder being absorbed at the lifting seat, reducing damage to the lead screw and lead screw nut from vibration and improving the lifespan of the lifting device. With the guide rails, the lifting seat is connected not only to the lead screw nut but also to the guide rails, and the guide rails and lifting seat are interlocked, increasing the stability of the entire lifting process and making the entire device more stable, preventing significant shaking during the lifting process of the shell-breaking cylinder.
