Definitions

  • the present invention relates to devices at rock drilling machines or similar machines which comprise a feed beam, a slide movable along the feed beam, and a drilling machine connected to the slide and defining the drill axis of a drill string.
  • the drilling machine is usually rigidly connected to the slide to which a feed force is applied which does not act coaxially with the drill axis.
  • the slide is subjected to a moment which tilts the slide backwards. This occurs partly because of play between the slide and the feed beam and partly because of deformations of the feed beam and the slide.
  • the drill string is subjected to a bending load from which risk for buckling and for contact with the edge of the drill hole will follow.
  • the latter risk is especially serious in connection with so-called diamond drilling which takes place at high numbers of revolution.
  • the drill string is rapidly cut off against the edge of the drill hole. This particulary if the drill string consists of aluminum tubes.
  • the drilling machine is connected to the slide by means of a hinge which is directed transversly to the drill axis such that the drill axis is situated between the hinge and the thrust line of the feed force.
  • An elastic element is arranged between the drilling machine and the slide and is so dimensioned relative to the distance between the hinge and the drill axis that the backward tilting of the slide is compensated.
  • a further advantage in the invention is that the vibration level is kept low because the stiffness of the suspension is different in different planes through the drill axis.
  • FIG. 1 shows a drill ring in which the invention forms a part.
  • FIG. 2 shows a part of the rig according to FIG. 1 on a larger scale.
  • FIG. 3 shows the machine in section according to 33 in FIG. 2.
  • the drill rig shown in FIG. 1 is mainly meant for drilling with diamond bits and comprises a frame 1.
  • the frame 1 is provided with runners 2 and a power aggregate 3 which comprises a motor and one or more hydraulic pumps.
  • the runners 2 can, if that be the wish, be substituted by wheels.
  • a holder 24 for a feed beam 4 is via a hinge 5 connected to the frame 1 and maneuvered by means of a hydraulic cylinder 6.
  • a hydraulic cylinder 7 is arranged to move the feed beam 4 in relation to the holder 24 via a fixture 25.
  • a motor 8 is arranged on the feed beam 4 for moving a drilling machine 12 along the feed beam 4 via a chain 9 in a conventional manner.
  • the feed beam is furthermore provided with a staiffily arranged chain 11 which cooperates with a sprocket on a reel 10.
  • This sprocket also cooperates with the chain 9.
  • a slide 13, 19 is, which is best shown in FIG. 3, by
  • the drilling machine 12 is connected to the slide 13, 19 by means of a hinge 20, 26 which consists of two screws 16 provided with pivots 20 which are arranged on the slide and cooperating with recesses 26 in the drilling machine.
  • the drilling machine 12 defines a drill axis 15 for a drill string 14.
  • the drill axis 15 is situated between the hinge 20, 26 and the thrust line of the chain 9.
  • An elastic element l7, 18, which consists of a rubber cushion 17 and two therewith by means of vulcanization connected metal plates 18, is connected partly to the slide l3, l9 and partly to the drilling machine 12 by means of screws 29.
  • a device relating to drilling machines and comprising a feed beam, a slide movable along the feed beam, and a drilling machine to which a drill string is connectable, said drilling machine being connected to the slide by means of a hinge, directed transversely to the drill axis of said drill string, and an elastic element arranged between the drilling machine and the slide for opposing rotation round said hinge, said drill axis being situated between said hinge and the feed beam.
  • a device in which the hinge comprises two pivots arranged on the slide and two therewith cooperating recesses in the drilling machine.
