Movable tool for repositioning anode assembly in electrolytic cell
The patent US12065752B2 describes a movable intervention tool specifically designed for repositioning the anode assembly of an electrolytic cell. The tool features a mount equipped with one or more bearing surfaces that provide stable support directly on elements of the electrolytic cell. This design allows for the intervention tool to be securely attached to a fixed element relative to the anode frame. The intervention unit is capable of vertical displacement of the anode assembly and includes mechanisms for tightening or loosening connectors that hold the anode assembly in place. Additionally, the tool incorporates position detection means and can be integrated with a handling device that facilitates movement along the superstructure of the electrolytic cell.
The handling device is equipped with a chassis that carries the intervention tool and includes displacement means for maneuvering the chassis over the superstructure. It features lifting mechanisms, such as a motorized hoist, to transition the intervention tool between a parking position and a working position. The design also includes guide means to ensure the tool follows a predetermined path during operation. The intervention device can accommodate multiple tools or a single tool on a rotary platform, enhancing its versatility. Overall, the invention aims to improve the efficiency and safety of maintenance operations within electrolytic cells by providing a reliable means for repositioning anode assemblies.
