Definitions

  • THIS INVENTION relates to a pile driver, pile drawer ond/or drilling machine for use in geological explorotion, mineral prospecting, mining, foundation engineering, building and the like.
  • Previously proposed drilling machines for small scale drilling operations comprise a collapsible most on a mobile chassis.
  • One disadvantage of this arrangement is that a single most is inadequate when a large number of holes are to be drilled, so that a number of machines must be used.
  • pile drivers comprise a frame which is erected above the spot where a pile is to be driven into the ground and is provided with one or more sets of guide rails along which a heavy weight is allowed to fall onto the pile, thus driving the pile into the ground.
  • Such pile drivers can thus only operate when the guide rails ore substantially vertical, although drilling machines which can drill horizontally have been previously proposed.
  • a further disadvantage of previously proposed pile drivers and drilling machines is that the some machine cannot be used both for pile driving and for drilling.
  • a machine which comprises a chassis carrying a turntable, on elongate lifting and/or tool carrying means and support means for the lifting ond/or tool carrying means, wherein the support means is mounted to a surface of the turntable so as to be rotatable relative to the turntable about two non-parallel axes irrespective of the orientation of the lifting and/or tool carrying means relative to the said surface, the orientation of one of the said axes of rotation being dependent on the rotation of the support means about the other of the said axes, and wherein the lifting and/or tool carrying means is rotatable with respect to the support means.
  • the present invention provides a machine which comprises a lifting and/or tool-carrying means and support means therefor, wherein the support means is rotatable about two non-parallel axes and comprises two members, one of which members is rotatably mounted on the other, and wherein the lifting and/or tool carrying means is fixed to the said rotatable member, the said rotatable member being rotatable by hydraulic or pneumatic means comprising two piston and cylinder arrangements pivotally connected to a first gear and operable in opposition so that, in use, when the piston of one piston and cylinder arrangement is extended the first gear rotates in one direction and when the piston of the other piston and cylinder arrangement is extended the first gear rotates in the other direction, the first gear meshing with a second gear disposed at right angles thereto the second gear being connected for rotating the said rotatable member.
  • the invention also provides a machine which comprises a lifting and/or tool-carrying means and support means therefor, wherein the support means is rotatable about two mutually perpendicular axes and the lifting and/or tool carrying means is rotatable with respect to the support means.
