Title (EN) DRILL ROD CLAMPING SYSTEM AND METHODS OF USING SAME
(FR) SYSTÈME DE SERRAGE DE TIGE DE FORAGE ET SES PROCÉDÉS D'UTILISATION
Abstract:
(EN) A drill rod clamping system for securing a drill rod in a selected position. The drill rod clamping system has a hollow spindle with an upper portion that defines axial slots and a base portion that defines at least one radial opening. A plurality of jaws are moveable radially inwardly to a drill rod gripping position and radially outwardly to a drill rod releasing position. Each jaw is received within a respective axial slot of the hollow spindle. An actuator moves the plurality of jaws between the drill rod gripping position and the drill rod releasing position. A compressed gas spring assembly exerts force on the actuator to close the jaws. A hydraulic operator exerts force on the actuator to overcome the force of the compressed gas spring assembly to open the jaws. The radial openings of the base portion of the spindle permit flushing of material flowing within the spindle.
(FR) La présente invention concerne un système de serrage de tige de forage pour fixer une tige de forage dans une position sélectionnée. Le système de serrage de tige de forage comporte une broche creuse avec une partie supérieure qui définit des fentes axiales et une partie de base qui définit au moins une ouverture radiale. Une pluralité de mâchoires sont mobiles radialement vers l'intérieur vers une position de saisie de tige de forage et radialement vers l'extérieur vers une position de libération de tige de forage. Chaque mâchoire est reçue dans une fente axiale respective de la broche creuse. Un actionneur déplace la pluralité de mâchoires entre la position de saisie de tige de forage et la position de libération de tige de forage. Un ensemble de ressort à gaz comprimé exerce une force sur l'actionneur pour fermer les mâchoires. Un opérateur hydraulique exerce une force sur l'actionneur pour compenser la force e l’ensemble de ressort à gaz comprimé pour ouvrir les mâchoires. Les ouvertures radiales de la partie de base de la broche permettent la purge de matériau s’écoulant dans la broche.
