Definitions

  • the present invention relates to a rock drilling rig and in particular to a rig having an extension boom.
  • the boom comprises two members which have square cross-sections.
  • the second boom member 15b is longitudinally movable relative to the first boom member 15a by means of a hydraulic cylinder 16' in the first boom member.
  • the first boom member is furthermore provided with a rotary motor positioned at about the midpoint of the first boom member 10,15a for rotation of the front part of the first boom member 15a relative to the rear part 10 of the first boom member. Because of the square cross-sections the second boom member 15b follows the front part of the first boom member in its turning movement.
  • the present invention aims at providing a rock drilling rig with an extension boom where the extension part of the boom is rotatable about the longitudinal axis of the boom by means of a motor positioned at the proximal end of the boom.
  • This gives the advantage of having the weight of the rotary motor near the carrier so that the boom does not have to be heavy in order to be sufficiently stiff.
  • Another advantage is that the rotary motor does not interfere with other manoeuvering means for the feed beam which sometimes are desirable.
  • An important advantage with the invention is that the extension and rotation movement of the boom can be guided in a common bearing arrangement which allows savings of weight and cost. All sensitive bearings for extension and rotation can with this invention be easily sealed off with a simple and reliable circular sealing which will significantly increase service life and decrease maintenance costs of the boom.
  • fig 1 shows a side view of a drill rig according to the invention.
  • Fig 2 shows a part of the drill rig and indicates possibilities of movement of the feed beam.
  • Fig 3 shows how a rock drilling machine can be moved close to the rock surface.
  • Fig 4 shows a longitudinal section through the boom of the drill rig.
  • Fig 5 is a section according to 5-5 in fig 4.
  • the rock drilling rig shown in the drawings comprises a carrier 11 on which a first elongated boom member 12 is mounted by means of a universal joint 13.
  • the first boom member is swingable relative to carrier 11 by means of two hydraulic cylinders 32, only one visible in the drawing.
  • a second elongated boom member 14 is guided by the first boom member for longitudinal movement therein.
  • a sliding bearing 28 is placed between the first and second boom members.
  • a rotary motor 17 is mounted at the rear or proximal end of first boom member 12 .
  • the outgoing shaft 19 of the rotary motor is by means of a splined coupling 29 connected with a hydraulic cylinder 18 which can be rotated by means of the rotary motor 17.
  • the external surface of the hydraulic cylinder is provided with a number of longitudinal lands 25 and intervening grooves 26.
  • the second boom member 14 is at its rear end of its internal surface provided with ridges 27 which extend into the grooves 26 of the hydraulic cylinder 18. In this way turning of hydraulic cylinder 18 is transferred to second boom member 14 independent of the position of the second boom member along the hydraulic cylinder.
  • a plastic sheet 30 is positioned over ridges 27 to form a bearing between hydraulic cylinder 18 and second boom member 14.
  • a piston 31 with a piston rod 20, having a longitudinal axis 21, are movable along the hydraulic cylinder 18 by means of hydraulic fluid entered into the hydraulic cylinder on either side of the piston 31. Piston rod 20 is connected with second boom member 14 so that movement of piston 31 causes relative longitudinal movement between the first and second boom members 12,14.
  • a boom head 24 comprising a turning motor 22 is mounted.
  • This turning motor makes it possible to turn the boom head about its axis 23 in addition to the movements made possible by the second boom member.
  • a holder 33 for the feed beam 15 is pivotable about a pivot 34 by means of a hydraulic cylinder 35.
  • Feed beam 15 is displaceable in holder 33 by hydraulic cylinder 36.
  • a rock drilling machine 16 is movable along feed beam 15 in a conventional way.

Claims (3)

  1. Ein Gesteinsbohrgerät mit einem Träger (11), einem ersten langgestreckten Auslegerelement (12), einem das hintere Ende des ersten Auslegerelementes mit dem Träger verbindenden Kreuzgelenk (13), einem durch das erste Auslegerelement für eine Längsbewegung relativ zu diesem geführten zweiten langgestreckten Auslegerelement (14), einem mit dem zweiten Auslegerelement schwenkbar verbundenen Vorschubbalken (15) und einer entlang dem Vorschubbalken bewegbaren Gesteinsbohrmaschine (16), einem Drehmotor (17) im ersten Auslegerelement (12) zum Drehen des zweiten Auslegerelementes (14) um seine Längsachse (21), einem mit der Austrittswelle (19) des Drehmotors verbundenen Hydraulikzylinder (18), wobei eine Kolbenstange (20) des Hydraulikzylinders mit dem zweiten Auslegerelement (14) verbunden ist, um relative Längsbewegungen zwischen dem ersten und dem zweiten Auslegerelement zu verursachen, dadurch gekennzeichnet, daß der Drehmotor (17) am hinteren Ende des ersten Auslegerelementes (12) montiert ist, daß die äußere Oberfläche des Hydraulikzylinders (18) mit einer Reihe von Längsstegen (25) und dazwischenliegenden Nuten (26) versehen ist, und daß die Innenfläche des zweiten Auslegerelementes (14) mit Rippen (27) für das Zusammenwirken mit diesen Nuten versehen ist, wodurch eine Aktivierung des Drehmotors ein Drehen des zweiten Auslegerelementes um seine Längsachse (21) relativ zum ersten Auslegerelement (12) verursacht.
  2. Ein Gesteinsbohrgerät gemäß Anspruch 1, dadurch gekennzeichnet, daß der Vorschubbalken (15) mit einem Auslegerkopf (24) schwenkbar verbunden ist, welcher am zweiten Auslegerelement (14) montiert ist und eine zur Längsachse (21) des zweiten Auslegerelementes (14) senkrechte Achse (23) besitzt.
  3. Ein Gesteinsbohrgerät gemäß Anspruch 2, dadurch gekennzeichnet, daß der Auslegerkopf (24) einen Drehmotor (22) umfaßt, mittels welchem der Auslegerkopf um seine Achse (23) drehbar ist.
