<p>Equipment for handling drill rods, comprising a slot-like storage space for storing drill rods side by side, a gripping jaw (13) for gripping the drill rod, and a linearly movable displacing arm for displacing the drill rod from the outlet opening of the storage space by a linear movement to the drilling centre of the drilling equipment and back. The equipment comprises a closing device (9) positioned in the outlet opening of the storage space (7) and movable in a direction transverse to the direction of movement of the displacing arm (11). The closing device (9) has two inclined support surfaces (9a, 9b) facing away from the storage space (7), and the displacing arm (11) similarly has an outwardly inclined guide surface (11a) at its end close to the storage space (7). On picking up a drill rod from the storage space (7), the gripping jaw (13) presses the closing device (9) at its support surface (9b) inwards so that the drill rod (3) to be picked up is able to push the closing device (9) inwards when the displacing arm is moved. Correspondingly, the guide surface (11a) of the displacing arm (11) pushes the closing device (9) inwards at its tip, so that the tip of the closing device (9) bears against the surface of the displacing arm (11) in such a way that they together close the outlet opening of the storage space (7) during the displacing movement.</p> |
