Title (EN) DRILLING DIRECTION CONTROL DEVICE
(FR) CONDUCTRICE DE FOREUSE EN FORAGE DIRIGE
Abstract: front page image
(EN)A drilling shaft deflection assembly for a drilling direction control device of the type comprising a rotatable drilling shaft and a housing for supporting a length of the drilling shaft for rotation therein. The deflection assembly is contained within the housing and is axially located between a first support location and a second support location for bending the drilling shaft between the first support location and the second support location. The deflection assembly includes a deflection mechanism for imparting lateral movement to the drilling shaft to bend the drilling shaft, a deflection actuator for actuating the deflection mechanism in response to longitudinal movement of the deflection actuator, and a deflection linkage mechanism between the deflection mechanism and the deflection actuator for converting longitudinal movement of the deflection actuator to lateral movement of the drilling shaft.
(FR)L'invention concerne un ensemble de flexion de corps de sonde équipant une conductrice de foreuse en forage dirigé, du type qui comprend un corps de sonde rotatif, et une enveloppe habillant une longueur du corps de sonde et dans laquelle tourne ce dernier. L'ensemble de flexion est logé dans l'enveloppe à une position axiale située entre un premier emplacement de support et un second emplacement de support pour fléchir le corps de sonde entre ces deux emplacements. L'ensemble de flexion comprend un mécanisme de flexion qui imprime un mouvement latéral au corps de sonde pour le fléchir; un actionneur de flexion qui accomplit un mouvement longitudinal pour actionner le mécanisme de flexion; et un mécanisme de liaison de flexion disposé entre le mécanisme de flexion et l'actionneur de flexion pour convertir un mouvement longitudinal de l'actionneur de flexion en un mouvement latéral du corps de sonde.
