Definitions

  • various types of drilling machines are known mounted for transportation on a truck or on a trailer or half trailer and provided with independent motive power units for rotating a cutting tool to form a hole, or enlarge a hole previously formed, in the ground.
  • the rods are contained in a well immediately adjacent to the borehole, to be taken up (or deposited) one by one by the driving head.
  • a further object of the invention is to provide a drilling machine comprising a simple and functional device for moving the driving head to enable it to tale up and/or deposit the individual drill rods when necessary.
  • the drilling machine comprises a series of hydraulic jacks 19 and mechanical screw jacks 20 to ensure that the drilling rig 10 is stable and vertical.
  • a cable, chain or other flexible transmission means 28 passes about upper end pulleys 27 on the tower 22 and has one end fixed at 29 ( Figures 1 and 3) to the truck 11 and its other end supporting a driving head of traditional type, indicated overall by 30, in which the drilling rods (not shown for simplicity) are clamped.
  • the driving head 30 is fixed to a frame 31 slidable vertically on the lattice 24 via rollers 32.
  • To this frame there is fixed at 33 ( Figure 3) one end of a secondary cable (or chain or other flexible means) 34, slidable about a pulley 35 pivoted in proximity to the lower end of the tower 22.
  • the other end of the secondary cable 34 is fixed at 36 to a fixed point on the lattice 24 via a tensioning device 46.
  • the frame 31 supports the driving head 30 via an articulated quadrilateral linkage composed of a pair of rigid arms 40 and 41, both pivoted both to the frame 31 and to the head 30 and comprising a hydraulic piston 42 hinged at 43 to the frame 31 and at 44 to a lug 45 welded to the arm 41.
  • the piston 42 of the articulated quadrilateral linkage is made to expand, to move the driving head 30 into the dashed configuration 30' to enable a new drilling rod taken from the service well to be fitted.
  • a main hydraulic circuit (not shown for simplicity) the piston 23 is made to expand, with consequent raising of the tower 22 within the lattice 24. During this movement the head 30 is raised upwards with twice the speed of the tower 22 plus the pulleys 27 and 35.
  • the jib crane 63 is mounted at the top of the drilling tower 122 and by means of a cable 80 supports a coupling device 81. This can be used both to carry the individual rods 50 from the containers 61 to the service well 151 and vice versa, and for hooking the top of the containers 61' when in their lying position and raising them into their erect position, or laying them on the ground on finishing boring.
  • the invention is not limited to the aforegoing description, which is to be considered purely as an illustration of the best method of implementing the equipment, and modifications in terms of the shape, dimensions and arrangement of the parts and of the constructional and operational details.
  • the base can be straight instead of arched, with the containers being consequently of comb arrangement when laid on the ground.
  • the invention includes all modifications which fall within its scope, as defined by the following claims.
