CA 2427754

Apparatus for gripping and releasing a tubular and comprising an elevator (13) having slips (15) for gripping and releasing a tubular (39,40). A spider (12) has slips (14) for gripping and releasing the tubular (33). A mechanically operated valve (18) is provided for controlling the supply of pressurised fluid to move the spider slips (14) between a gripping position and a release position, with sensor means (28) detecting when the elevator slips (15) are in the gripping position. Means (31) mechanically inhibits movement of the valve (18) to a position in which the spider slips (14) release the tubular (40) when said sensor means (28) detects that the elevator slips (15) are not in a correctly gripping position. A second valve (20) controls movement of the elevator slips (15) and a guide plate (24) links control of both valves (18, 20).

Appareil pour saisir et relâcher des tubulaires qui comprend un élévateur (13) possédant des éléments glissants (15) destinés à saisir et relâcher des tubulaires (39,40). Une araignée (12) comporte des éléments glissants (14) pour saisir et relâcher des tubulaires (33). Une vanne à commande mécanique (18) sert à commander l'alimentation d'un liquide sous pression pour déplacer les éléments glissants (14) de l'araignée entre une position de prise et une position de relâchement, et un système de capteurs (28) détecte la position de prise des éléments glissants (15) de l'élévateur. Un système (31) ralentit mécaniquement le mouvement de la soupape (18) dans une position dans laquelle les éléments glissants (14) de l'araignée relâchent le tubulaire (40) lorsque le système de capteurs (28) détecte que les éléments glissants (15) de l'élévateur ne se sont pas mis correctement dans une position de prise. Une deuxième vanne (20) commande le mouvement des éléments glissants (15), et une plaque de guidage (24) relie les commandes des deux vannes (18, 20).
