Abstract

Cette invention concerne un dispositif de glissement d'électrode (1), comprenant une bague de support supérieure (2) et une bague de support inférieure (3) ayant un ou plusieurs ensembles de serrage comprenant un sabot de serrage (4) et un dispositif de serrage (5). Le sabot de serrage (4) peut être actionné entre une position de serrage et une position de libération. Le dispositif de serrage (5) comprend un élément de cadre (6) pouvant être solidarisé à une bague de support (2, 3) de sorte à être fixe par rapport à la bague de support, une partie de cylindre (7), un plongeur (8) et un ressort de pression (11) disposé à l'intérieur du logement cylindrique (9) du plongeur (8) pour pousser le plongeur (8) vers le sabot de serrage (4) et pour pousser en force le sabot de serrage (4) contre l'électrode (E). Une barre de tension (12) est fixée de manière amovible à la plaque d'extrémité (10) du plongeur (8). Un élément de piston est disposé mobile à l'intérieur de la partie de cylindre pour former des moyens de commande hydraulique (16). Le dispositif de serrage (5) comprend une barre de tension unique (12) agencée de manière centrale par rapport à l'élément de cadre (6), au plongeur (8), au ressort de pression (11) et à l'élément de piston (15).
