Handling device for intervention on electrolytic cell superstructure
The granted patent US12043913B2 describes a handling device designed for conveying an intervention tool to perform operations on an electrolytic cell equipped with a superstructure. The device features a chassis that supports the intervention tool and is capable of movement above the superstructure. It includes displacement means that allow the chassis to move while resting against the superstructure. Additionally, the handling device is equipped with lifting means to raise or lower the intervention tool between a rest position, where it is kept away from the electrolytic cell, and a working position, where it can make contact with the cell. Various configurations for the lifting means are outlined, including cable lifting systems and motorized hoists, along with guide means to ensure the intervention tool follows a predetermined path during operation.
Further claims detail the intervention device’s components, including a mount for the intervention tool that provides stable support on the electrolytic cell. The mount features reversible attachment means for secure connection to the cell’s elements. The intervention tool may also include a movable part designed to engage with an anode rod, facilitating the securing and manipulation of the rod within the cell. The patent also describes the electrolytic cell itself, which comprises a superstructure and an anode frame, with the intervention device integrated to allow for efficient operation. The displacement means are designed to guide the chassis along the superstructure, ensuring smooth movement over the entire length of the anode frame, with provisions for storage and drive mechanisms to enhance functionality.
