Abstract

L'invention concerne un dispositif de raccordement Le dispositif comporte un corps annulaire 14 s'emmanchant sur l'élément 10 à raccorder, des griffes de verrouillage 32 pouvant coulisser radialement dans le corps en direction de l'élément 10, des biellettes de liaison à genouillère 34 articulées sur les griffes 32 et sur des paliers 44, un chariot annulaire 30 mobile longitudinalement et portant les paliers 44, un ressort annulaire 46 porté par le chariot 30 et des pistons à double effet 21 dont les tiges 22 sont reliées au chariot 30 et servent à le déplacer en va-et-vient, ce qui provoque le verrouillage ou le déverrouillage des griffes. Application notamment au raccordement de conduits sur des têtes de puits sous-marins.The invention relates to a connecting device. The device comprises an annular body 14 which engages on the element 10 to be connected, locking claws 32 which can slide radially in the body in the direction of the element 10, connecting rods to toggle 34 articulated on the claws 32 and on the bearings 44, an annular carriage 30 movable longitudinally and carrying the bearings 44, an annular spring 46 carried by the carriage 30 and double-acting pistons 21 whose rods 22 are connected to the carriage 30 and are used to move it back and forth, which causes the locking or unlocking of the claws. Application in particular to the connection of conduits to subsea well heads.
