The invention relates to a device for the mechanical and electrical rotatable connection (100) between a transportation module (6) and the material handling and interaction organs of an aluminium producing plant by fire electrolysis. The inventive device is characterised in that it comprises a fixed rack (101) provided with a core (102) and a sleeve (121) which encompasses the core (102) and rotates therearound, first (110) and second (120) rotatable racks rotating around the sleeve (121), sliding and rotatable electric contacts (113, 114) between the bodies and an actuating system (140, 141, 142, 150, 151, 152) which initiates the rotation of the racks with respect to each other around a common axis (103). The inventive connecting device makes it possible to carry out an angularly unlimited rotation between three racks providing with a permanent electrical contact therebetween.
L'invention a pour objet un dispositif de liaison mécanique et électrique rotatif (100) entre un module de transport (6) et des organes de manutention et d'intervention d'une usine de production d'aluminium par électrolyse ignée, caractérisé en ce qu'il comprend un châssis dit "fixe" (101) muni d'un moyeu (102), un manchon (121) entourant le moyeu (102) et apte à tourner autour de celui-ci, un premier (110) et un deuxième (120) châssis dits "rotatifs" aptes à tourner autour du manchon (121), des contacts électriques glissants rotatifs (113, 114) entre les châssis et des systèmes d'entraînement (140, 141, 142, 150, 151, 152) pour provoquer la rotation des châssis les uns par rapport aux autres autour d'un axe commun (103). Le dispositif de liaison selon l'invention permet une rotation angulairement illimitée entre les trois châssis, tout en assurant une liaison électrique permanente entre ceux-ci.
