The intelligent pole changing system for anode height measurement is used in the electrolytic aluminum industry. It is a device that realizes automatic measurement of new and old anodes during the process of changing anodes in the electrolysis workshop. It has the characteristics of more convenient, fast and higher accuracy than the traditional comparison base measurement and marking method, and effectively improves the work efficiency of anode replacement of multi-functional units. The application of the intelligent pole changing system for anode height measurement of electrolytic multi-functional crane not only greatly reduces the pole changing error and meets the production process requirements, but also reduces the labor intensity and production cost of workers, and eliminates the safety hazards of pole changing operations. At the same time, the electrolytic multi-function crane anode height measurement intelligent pole changing system has significantly improved the process technology level and core equipment automation and production efficiency of the electrolytic aluminum industry, and is conducive to the realization of intelligent workshop technology and industrial Internet of Things. It is an indispensable automation equipment for the electrolytic aluminum industry to enhance the competitiveness of enterprises in the future. It has very good market prospects and promotion and application value.
