Title (EN) APPARATUS FOR DISCONNECTING DRILL RODS
(FR) DISPOSITIF DE DEMONTAGE DE TIGES DE FORAGE
Abstract: front page image
(EN) An apparatus (10) for disconnecting a drill rod (30) from a string of drill rods is arranged to be mounted to a drilling rig (42). The apparatus (10) includes a body (11) having an opening (28) arranged to loosely receive the drill rod (30) and a plurality of jaws (12, 14) which are arranged to exert a clamping force on the drill rod (30). Jaw (14) is arranged such that the clamping force exerted on the drill rod (30) is increased as the body (11) is rotated about the longitudinal axis of the drill rod (30).
(FR) Selon la présente invention, l'appareil (10) à démonter les tiges de forage (30) d'un train de tiges est agencé pour se monter sur une installation de forage (42). L'appareil (10) comporte un corps (11) pourvu, d'une part d'une ouverture (28) se présentant de façon à recevoir sans contrainte importante le train de tiges (30) et d'autre part d'une pluralité de mâchoires (12, 14) se présentant de façon à exercer une force de serrage sur la tige de forage (30). L'ensemble mâchoires (14) est agencé de façon que la force de serrage s'exerçant sur la tige de forage (30) augmente lorsqu'on fait tourner le corps (11) autour de l'axe longitudinal de la tige de forage (30).
