Definitions

  • the present invention relates to a drilling machine, more specifically a drilling machine intended for removably coupling to a machine for manoeuvring the drilling machine, e.g. an excavator.
  • the excavator can thus be utilized optionally for excavating or drilling, and when the excavator is utilized during drilling the person normally carrying. out drilling and who is idle during excavating work may be appointed to other tasks.
  • a still further object is to provide a drilling machine connectable to an operating machine and which comprises a hand drilling machine modified with simple means and in a simple way.
  • Figure 1 is a schematic side view of a portion of a drilling machine in accordance with the invention, coupled to gripping means on the bucket of an excavator, and
  • Figure 2 is a schematic side view of the drilling machine in accordance with Figure 1 , coupled to the excavator bucket in a different angular attitude relative thereto.
  • the drilling machine in accordance with the invention comprises an ordinary pneumatic or hydraulic drilling machine 1 , of which an upper portion is illustrated in Figures 1 and 2, and which is provided with two handles 2 and 3, with the aid of which the user operates the drilling machine during manual drilling, the inventive drilling machine also including a means 4 attached to the machine 1.
  • the means 4 includes a holder 5 partially surround ⁇ ing a head 6 on the upper portion of the machine 1 , and with the aid of which a bolt 7 and handles 2 and 3, which are threaded on a shaft 8 taken through the head 6 and removable therefrom, are removably attached to the head 6.
  • a rubber block 9 is attached to the upper side of the holder 5.
  • the upper portion of the rubber block 9 is attached to the lower portion of a tube 10, and to the lower portion of a piston rod 11 incorporated in a gas spring which also includes a cylinder 12.
  • a tube 13, the interior cross section of which somewhat exceeds the exterior cross section of the tube 10 is telescopically displaceable on the tube 10 and is provided with a slot 14, in which thrusts a pin 15 attached to the tube 10. Withdrawal of the tube 10 from the tube 13 is restricted by the pin 15 when it contacts a locking plate 16, attached to the lower portion of the tube 13, and cover ⁇ ing the open, lower portion of the slot 14.
  • the pin 15 and slot 14 serve as guide means for preventing rotary movement between the tubes 10 and 13. Such movement is also inhibited by the tubes themselves, if they are made with a quadratic cross-section.
  • the upper portions of the cylinder 12 and tube 13 are attached to two members 17 and 18, the upper ends of which are attached to the ends of a circular tube 19.
  • the gripping arms 20 and 21 are inserted in both ends of the tube 19 in the manner illustrated in Figure 1, said gripping arms 20 and 21 being pivotably mounted on an excavator bucket 22 provided with a recess 23, e.g. of the kind described in the Swedish Patent 7714027-5 and marketed under the registered trade name of CRAB JOHN.
  • the drilling machine 1, 4 can lie on the ground during this procedure.
  • the bucket is then lifted to a suitable height, during which the machine 1, 4 assumes a substantially vertical position, since the gripping arms are not clamped in the tube but only loosely inserted therein.
  • the bucket is then lowered
  • the lateral misalignment forces to which the drilling machine 1 , 4 is subjected during drilling are taken up by the rubber block 9 which thus functions as a yielding joint.
  • drilling machine 1 , 4 When the drilling machine 1 , 4 is to be used for horizontal drilling, the gripping arms 20, 21 grip round the tube 19 in the manner illustrated in Figure 2, the bucket 22 then being lifted and taken toward the material to be drilled.
  • the gas spring 11, 12 and block 9 take up the forces acting on the drilling machine 1 , 4 in horizontal drilling as well, so that effective drilling without damage to the machine 1 , 4 is achieved.
  • drilling can also be executed in directions other than those illustrated on the drawings, and the directions corrected during work by manoeuvring the bucket 22 an d machine 1 , 4 so as to alter the angle between the gripping arms 20, 21 and the tube 19 when the arms grip the tube as in Figure 1 , or as in Figure 2.
  • the rubber block and/or the gas spring 11, 12 can comprise any kind of elastic elements at all, such as one or more springs. The invention is thus only restricted by what is disclosed in the claims.

Abstract

Une perforatrice comporte un mécanisme de couplage (19) pour coupler de manière libérable la perforatrice (1) au godet d'une excavatrice à l'aide de bras de saisie (20, 21). Entre la perforatrice et le mécanisme de couplage se trouve un organe en caoutchouc (9) compensant les contraintes dues à un défaut d'alignement, ainsi qu'un ressort à gaz (11, 12) compensant les contraintes dues à des chocs et à des compressions survenant pendant la perforation.
