PCT No. PCT/FI94/00245 Sec. 371 Date Dec. 28, 1995 Sec. 102(e) Date Dec. 28, 1995 PCT Filed Jun. 8, 1994 PCT Pub. No. WO95/00737 PCT Pub. Date Jan. 5, 1995Equipment for handling drill rods, comprising a slot-like storage space for storing drill rods side by side, a gripping jaw 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 center of the drilling equipment and back. The equipment comprises a closing device positioned in the outlet opening of the storage space and movable in a direction transverse to the direction of movement of the displacing arm. The closing device has two inclined support surfaces facing away from the storage space, and the displacing arm similarly has an outwardly inclined guide surface at its end close to the storage space. On picking up a drill rod from the storage space, the gripping jaw presses the closing device at its support surface inwards so that the drill rod to be picked up is able to push the closing device inwards when the displacing arm is moved. Correspondingly, the guide surface of the displacing arm pushes the closing device inwards at its tip, so that the tip of the closing device bears against the surface of the displacing arm in such a way that they together close the outlet opening of the storage space during the displacing movement. |
