20150144402 | HANDLING DEVICE AND METHOD FOR HANDLING DRILL STRING COMPONENTS IN ROCK DRILLING AND ROCK DRILL RIG - A handling device for handling drill string components with respect to a rock drill rig including a rotator device supported on a feed beam and arranged to rotate and drive a drill string component. A gripper grips drill string components. The gripper is swingably supported around a first swing axis between: a first position aligned with the active drill string position, and a second position aligned with a delivering position for drill string components. A swing arm includes a support configured to support a drill string component and is swingable around a second swing axis. A guiding beam is fastenable at end regions in connection with respective regions of the first and second swing axis. The guiding beam forms mechanical stops for the gripper in the second position and for the swing arm in the delivering position. Also, a rock drill rig and a method. | 05-28-2015 |
20130037324 | DEVICE AND METHOD FOR HANDLING DRILL STRING COMPONENTS AND DRILL RIG - A device for handling drill string components for a drill rig. A slide is arranged displaceable on a longitudinal guide. A grip unit is swingable between a first position for receiving and delivering of drill string components beside the drill rig and a second position for assembling and disassembling of drill string components in the drill rig. The grip unit includes a rotator unit for rotation of a gripped drill string component. A rotational actuator supported by the slide has a rotational axis forming an angle with the length guide. A swing unit includes a first link portion that is connected to the rotational axis. A second link portion is connected to the grip unit and a swing joint portion. | 02-14-2013 |
20120313422 | METHOD AND DEVICE FOR WORKING ROCK - A method and rig for driving tunnels, galleries, shafts or the like. The rig has a movable base unit that over a support unit supports a carrying unit which in turn carries a cutting head having outwardly directed cutting elements. The method includes rotating the cutting head around a general axis of rotation and applying the cutting head against a rock surface to be worked. The carrying unit is swung into a first chosen mutual position in respect of the support unit. The support unit is rotated into a second chosen mutual position with respect to the base unit around an axis that is essentially longitudinal with respect to the base unit. An angle of operation of the cutting head is controllable. | 12-13-2012 |
20120125612 | OVERSHOT DEVICE - A device with an overshot including a first part with an elongated body adapted to be connected to a hoisting line in one end and with a tubular opening arranged/designed to receive a spearhead in the other end. The overshot further includes a second part with a scissor like mechanism including two lifting dogs arranged to pivot around a common pivot pin. The lifting dogs are connected via a biasing unit and the elongated body includes a central, axially extending slot. The scissor like mechanism is arranged with the common pivot pin sliding in the slot between a first end position where the biasing unit is arranged to close the lifting dogs such that a spearhead received in the tubular opening is locked and a second end position where an opener including an opening pin is arranged to force the lifting dogs open against the force of the biasing unit, such that a spearhead received in the tubular opening is released. | 05-24-2012 |
20090052995 | Arrangement for injecting and affixing a reinforcing or anchoring element in a rock wall - The present invention relates to an arrangement and to a method for injecting and affixing a reinforcing and/or anchoring element in a rock wall. The arrangement includes means ( | 02-26-2009 |
