Title (EN) MECHANICAL ROTATING CONTROL DEVICE LATCH ASSEMBLY
(FR) ENSEMBLE DE VERROUILLAGE DE DISPOSITIF DE COMMANDE ROTATIF MÉCANIQUE
Abstract:
(EN) A remotely and mechanically actuated RCD control tool adjusts at least one component of an RCD latch assembly between at least two settings. The mechanical RCD control tool comprises a rotational cylinder and a guide cylinder, the rotational cylinder configured to rotate in a rotational direction to adjust the RCD latch assembly from a first setting to a second setting and from the second setting to the first setting based on movement of the drive cylinder in a selected direction. Additional apparatus, methods, and systems are disclosed.
(FR) L'invention concerne un outil de commande RCD actionné à distance et mécaniquement qui règle au moins un composant d'un ensemble verrou RCD entre au moins deux réglages. L'outil de commande RCD mécanique comprend un cylindre rotatif et un cylindre de guidage. Le cylindre rotatif est configuré pour tourner dans un sens de rotation afin de régler l'ensemble verrou RCD d'un premier réglage à un deuxième réglage et du deuxième réglage au premier réglage en fonction du mouvement du cylindre d'entraînement dans une direction sélectionnée. L’invention concerne en outre un appareil, des procédés et des systèmes supplémentaires.
