Device and method for handling drill string components and drill rig

摘要

A device (1) for handling drill string components (28) for a drill rig (13) includes a slide (3) which is arranged displaceable on a longitudinal guide (2), a grip unit (7) being swingable between a first position for receiving and delivering of drill string components beside the drill rig (13) and a second position for assembling and disassembling of drill string components in the drill rig (13), wherein said grip unit includes rotator means (26,27,29,30) for rotation of a gripped drill string component (28). A rotational actuator (8) being supported by the slide (3) has a rotational axis forming an angle with the length guide (2). A swing unit (4) includes a first link portion (11) which is connected to said rotational axis, a second link portion (12), which is connected to the grip unit (7) and a swing joint portion (10).
