The invention relates to an element (300) for handling an anode connector (200) which is equipped with two lateral trunnions (212, 212') and a clamping screw (210). According to the invention, the aforementioned connector can co-operate with the hook fasteners (10, 10') of a cell (1) for the production of aluminium by means of fused-salt electrolysis, such that anodes can be connected to said cell. Moreover, the inventive element comprises a clamping member (302) which can co-operate with the clamping screw (210) of the connector, such as to alter the clamping condition thereof. The invention is characterised in that it comprises a locking system (310, 310', 320) which can co-operate with the clamping member (302) and the connector (200), such as to lock the latter in a determined position, known as the normal position, in the handling element (300) by loosening the connector using the clamping member. The invention is further characterised in that it also comprises at least one mobile member (312, 312') having an open position and a closed position and in that each mobile member (312, 312') consists of: a support (313, 313') which can support the connector (200) in the closed position, typically by means of the above-mentioned lateral trunnions (212, 212'); and a means (315, 315') for moving each mobile member (312, 312') from the closed position to the open position. The invention prevents a connector from being dropped during the handling thereof.
L'invention a pour objet un organe de manutention (300) d'un connecteur d'anode (200) muni de deux tourillons latéraux (212, 212') et d'une vis de serrage (210), ledit connecteur étant apte à coopérer avec des crochets de fixation (10, 10') d'une cellule (1) de production d'aluminium par électrolyse ignée de manière à permettre le raccordement d'anodes sur ladite cellule, ledit organe comportant un organe de serrage (302) apte à coopérer avec la vis de serrage (210) du connecteur de manière à modifier son état de serrage, et caractérisé en ce qu'il comporte un système de blocage (310, 310', 320) apte à coopérer avec l'organe de serrage (302) et le connecteur (200) de manière à bloquer celui-ci dans une position déterminée, appelée position normale, dans l'organe de manutention (300) par desserrage du connecteur à l'aide de l'organe de serrage, en ce qu'il comporte en outre au moins un membre mobile (312, 312') ayant une position ouverte et une position fermée et en ce que le ou chaque membre mobile (312, 312') comprend un support (313, 313') apte à supporter le connecteur (200), typiquement par lesdits tourillons latéraux (212, 212'), dans la position fermée et un moyen (315, 315') pour provoquer le déplacement du ou de chaque membre mobile (312, 312') de la position fermée à la position ouverte. L'invention permet d'éviter les chutes intempestives d'un connecteur lors de sa manutention.
