Abstract

La présente invention vise un appareil mécanique servant à visser et à dévisser les joints d'une tige de forage, comportant un cylindre de serrage (24) à déplacement en sens unique, conçu pour visser et dévisser les raccords de tiges. Le cylindre est du type à trois mâchoires (21, 22, 23), les mâchoires supérieure et inférieure (21, 23) étant identiques, et les trois étant reliées par un bâti commun. D'autres cylindres referment les mâchoires (36, 37) à chaque niveau. L'appareil se déplace dans le sens vertical. Une combinaison de deux mâchoires sert à visser les joints, et une autre combinaison de deux mâchoires sert à les dévisser. Des outils à came (66) spéciaux servent à retenir les tiges. Des dispositifs (94, 101) servent à repositionner la mâchoire médiane après chaque intervention sur des tiges de diamètres différents. Les mâchoires sont constituées de paliers, d'une articulation et de réglages spéciaux (66, 73). Elles fonctionnent dans un seul sens et sont autoserrantes.
