A Toggled Breakout Wrench is described for use with a drilling rig having a drill stem made up of one or more drill pipe sections. The wrench comprises an arm movably connected to the drilling rig such that the arm will move in a substantially arcuate path about a drill pipe section. Pivotally mounted to the arm are a pair of opposed jaws for clamping about the drill pipe section to assist in breaking loose the threaded connections of the drill pipe sections. A toggle linkage enables the opposed jaws to move between a clamping and a non-clamping position about the drill pipe section.

La présente invention concerne une clé de dévissage à mâchoires articulées destinée à une installation de forage dont la masse-tige est constituée d'une ou plusieurs tiges de forage. La clé comporte un bras mobile monté sur l'installation de forage de façon que le déplacement du bras décrive un arc de cercle enveloppant la tige de forage. Deux mâchoires montées face à face s'articulent sur le bras de façon à se serrer sur le pourtour de la tige de forage pour faciliter le déblocage de séparation des raccords filetés entre les tiges de forage. Grâce à des articulations à genouillère, les mâchoires face à face évoluent entre une position serrée et une position desserrée par rapport à la tige de forage.
