Abstract
This intervention tool is movable and designed to reposition an anode assembly of an electrolytic cell. The intervention tool comprises a mount provided with one or more bearing surfaces allowing the intervention tool to bear and be stably supported directly on at least one element of the electrolytic cell, and an intervention unit designed to reposition the anode assembly.
Claims25
A movable intervention tool in combination with an electrolytic cell, the movable intervention tool operable to reposition an anode assembly of the electrolytic cell, the intervention tool comprising:
- a mount provided with one or more bearing surfaces seated upon the electrolytic cell for fully supporting the intervention tool directly on at least one element of the electrolytic cell;
- and
- an intervention unit operable to reposition the anode assembly.
An intervention device designed to reposition an anode assembly of an electrolytic cell, the intervention device comprising:
- an intervention tool having a mount provided with one or more bearing surfaces for allowing the intervention tool to bear and be stably supported directly on at least one element of the electrolytic cell, and an intervention unit designed to reposition the anode assembly;
- and
- a handling device having a chassis carrying the intervention tool, and displacement means adapted to allow displacement of the chassis, the displacement means being adapted to bear on a superstructure of the electrolytic cell.
An electrolytic cell comprising:
- a superstructure;
- an anode assembly including an anode frame supported by the superstructure;
- and
- an intervention device including:
- an intervention tool having a mount provided with one or more bearing surfaces for allowing the intervention tool to bear and be stably supported directly on the superstructure of the electrolytic cell, and an intervention unit designed to reposition the anode assembly;
- a handling device having a chassis carrying the intervention tool, and displacement means adapted to allow displacement of the chassis, the displacement means being adapted to bear on a superstructure of the electrolytic cell;
- wherein the superstructure comprises a surface on which the displacement means are bearing.
