The invention relates to a service module for factories producing aluminium by fusion electrolysis. The turret (9) of the inventive service module (7) is provided with a determined tool set, wherein each tool (101, 102, 103) is mounted on a telescopic arm (111, 112, 113) which is fixed to the turret (9) by a hinge support (121, 122, 123) which enables said telescopic arm to be perpendicularly movable with respect to a determined hinge point without rotating around the main axis thereof. Said telescopic arms are interconnected by a mechanical connection device (200) which maintains the relative angular deviation between the perpendicular movements thereof within a given tolerance range. Said invention makes it possible to bring the tools closer without striking each other during the use thereof.

L'invention porte sur un module de service destiné aux usines de production d'aluminium par électrolyse ignée. Selon l'invention, la tourelle (9) du module de service (7) est équipée d'un ensemble déterminé d'outils, dont chaque outil (101, 102, 103) est monté sur un bras télescopique (111, 112, 113) fixé à la tourelle (9) par un support articulé (121, 122, 123) qui permet des mouvements pendulaires du bras télescopique par rapport à un point d'articulation déterminé tout en interdisant les mouvements de rotation du bras télescopique autour de son axe principal. Les bras télescopiques sont reliés entre eux par un dispositif de liaison mécanique (200) apte à maintenir dans un domaine de tolérance déterminé l'écart angulaire relatif entre les mouvements pendulaires des bras télescopiques. L'invention permet de rapprocher les outils les uns des autres sans risquer qu'ils se percutent en cours d'utilisation.
