Title (EN) DEVICE FOR GRIPPING AN ANODE FOR LIFTING OPERATIONS AND METHOD FOR OPERATING SAME
(FR) DISPOSITIF DE PRÉHENSION D'ANODE POUR MANŒUVRES DE LEVAGE ET SON PROCÉDÉ DE MANIEMENT
Abstract:
(EN) The invention relates to a gripping device (21) for mating an anode rod (1) having a recess (9) between two legs (2, 3) at its top end, and further having a bolt (6) securely fixed in the legs. The invention also relates to a method for operating the gripping device. The gripping device (21) has an overall frame structure (15, 15') provided with two locking elements (7, 8) pivotably arranged in supports (9, 10). The locking elements (7, 8) are allowed to rotate from a fixed position to provide a gap between them as the lifting device (21) and the top end of the anode rod (1) are mated. The locking elements (7, 8) are rotated back to the fixed position after the bolt (6) has passed the gap thereby locking the lifting device (21) to the anode rod. The anode rod (1) can be released from the gripping device (21) by moving at least one support (9, 10) apart from the other, and thereby forming a gap between the locking elements (7, 8) allowing the bolt (6) to pass in a reverse direction through said gap.
(FR) L'invention concerne un dispositif de préhension (21) destiné à s'accoupler à une tige d'anode (1), présentant un évidement (9) entre deux jambes (2, 3) à son extrémité supérieure, et pourvu en outre d'un boulon (6) solidement fixé dans les jambes. L'invention concerne également un procédé destiné à manier le dispositif de préhension. Le dispositif de préhension (21) présente une structure de cadre globale (15, 15') pourvue de deux éléments de verrouillage (7, 8) disposés à pivotement dans des supports (9, 10). Les éléments de verrouillage (7, 8) peuvent tourner depuis une position fixe pour former un espace entre eux lorsque le dispositif de levage (21) et l'extrémité supérieure de la tige d'anode (1) sont accouplés. Les éléments de verrouillage (7, 8) sont tournés de nouveau vers la position fixe après que le boulon (6) a traversé l'espace, fixant ainsi le dispositif de levage (21) à la tige d'anode. La tige d'anode (1) peut être libérée du dispositif de préhension (21) par déplacement d'au moins un support (9, 10) à distance de l'autre, ce qui crée un espace entre les éléments de verrouillage (7, 8) et permet au boulon (6) de traverser ledit espace en sens inverse.
