Abstract
A rod positioning device for aligning a drilling rod with a rod string having complementary mating threads, comprising a base, an arm mounted to the base about a first rotation axis, and a rod-gripping device mounted on the arm. The arm is for displacement about the first rotation axis between a rod loading position and a rod alignment position. The rod-gripping device is for operating between a rod-gripping configuration and a rod-releasing configuration. The rod-gripping device comprises jaws for gripping the drilling rod while the rod-gripping device is in the rod-gripping configuration and the arm is in the rod loading position, and guiding elements mounted on the jaws, the guiding elements aligning the drilling rod with the rod string and enabling longitudinal displacement of the drilling rod to contact the rod string.
