Definitions

  • the invention relates to a drilling device with a tubular outer rod carrying a ring drill bit, an inner rod running in the outer rod, a central inner bit bearing inner rod, a common feed device for both rods in the form of a carriage which can be moved in the longitudinal direction of the rod and which has a rotary drive for the outer rod and a rotary percussion drive for the inner linkage, and with an adjusting device for changing the mutual distance between rotary impact drive and rotary drive on the slide.
  • a known drilling device of this type (DE-OS 29 24 393) is provided with a rotary drive for the outer linkage.
  • the inner rod extends through the rotary drive.
  • a rotary impact drive is attached to the slide in axial alignment with the rotary drive. While the inner rod is being rotated and struck, the outside becomes boom only rotated.
  • the rotation suppression g drive can be adjusted relative to the rotary drive in the axial direction of the rod to change in the borehole, the axial position of the centric réellebohrkrone with respect to the ring bit.
  • it is possible to extend the inner drill bit operate both drill bits at the same height, or pull the inner drill bit back to seal the outer rod against water or quicksand. In any case, the outer linkage is only rotated while the inner linkage is rotated and struck.
  • a drilling device requires only a single rotary drive for both rods.
  • the inner linkage and the outer linkage cannot be adjusted relative to one another, so that the two drill bits are always in a fixed axial relationship to one another.
  • the outer rod Since the outer rod is subjected to blows that are transmitted to the borehole wall, the soil near the borehole wall is compacted. The compacted soil tightly surrounds the outer boom and prevents the two booms from rotating together.
  • the directional accuracy suffers from hitting the outer linkage.
  • the pipes of the outer linkage are subject to high wear due to the constant impact.
  • drilling devices are known in which an eccentric drill bit is attached to the front end of the inner rod, which is rotated and struck while the outer rod is only rotated.
  • the eccentric drill bit drills a hole that is larger than the inner diameter of the outer rod, so that the outer rod can be easily pushed under rotation.
  • eccentric drill bits When using eccentric drill bits, the directional accuracy of the drilling is poor.
  • a drilling device For drilling in earthy soils, a drilling device with a central inner core bit that is turned and struck and with a ring core bit that is only turned is particularly suitable.
  • the rotating (not beaten) outer rod does not cause soil compaction and the impacts on the inner rod are transmitted to the inner drill bit through the surrounding soil without damping. If you encounter rock temporarily during such drilling work, the inner core bit works its way through this rock, but the ring core bit, which is only rotated, cannot follow. For this reason, in the event of such difficulties, at least part of the drilling equipment must be replaced in order to overcome the difficult section of the borehole. This requires a considerable amount of material, which must be kept at the drilling site, in terms of time and assembly work.
  • the invention has for its object to provide a drilling device of the type mentioned can work in different operating modes in different soil conditions with high propulsive power without having to replace parts of the drilling device.
  • a pipe section passing through the rotary drive is attached to the rear end of the outer linkage, the end of which lies behind the rotary drive, and that the inner linkage has a radially projecting ring collar in the area between the rotary drive and rotary impact drive, the front of which Front side can be attached by the adjusting device against the end of the pipe section.
  • the drilling device according to the invention is used in light soils in such a way that the outer rod is only rotated and the inner rod is rotated and struck. This results in the greatest possible drilling with high directional accuracy of the drilling.
  • the blows of the inner drill bit not only cause the axial expansion of the drill hole, but they also radially radiate into the area covered by the ring drill bit, so that the material in front of the exclusively rotating ring drill bit is partially loosened and the ring drill bit can then easily remove this material . If one encounters rocky ground at the bottom, the inner tube is advanced relative to the outer tube until the ring collar of the inner tube abuts against the pipe section which forms the rear end of the outer tube.
  • the drilling device according to the invention can optionally be used in two operating modes by simply axially displacing the two rods relative to one another, the outer rod being struck only when the ground conditions so require.
  • Front generally refers to the direction facing the bottom of the borehole, ie the direction of drilling, while “rear” denotes the opposite direction.
  • the end of the pipe section and the end face of the ring collar can have flat surfaces which can be placed against one another. As a result, the impact energy that is transmitted from the inner linkage to the outer linkage is distributed over a relatively large transmission area.
  • the end of the pipe section and the end face of the ring collar have interlocking toothings for the rotationally fixed coupling of the outer linkage and inner linkage.
  • the ring works here collar and the pipe section not only as impact transmission elements, but also for the rotationally fixed coupling of both rods.
  • the rotary drive of the inner linkage supports the rotary drive of the outer linkage. While the outer rod rubs against the borehole wall and has to overcome a high rotational resistance, the performance of the rotary drive of the inner rod is generally not fully utilized.
  • the support of the rotary drive of the external linkage acts by those of the internal linkage advantageous.
  • the pipe section of the outer linkage should be mounted in a longitudinally displaceable manner in the corresponding rotary drive, so that blows which are exerted on the pipe section via the ring collar do not act on the rotary drive. Adequate clearance must therefore be provided so that the pipe section can dodge axially with every impact.
  • a spring device should be attached to this housing in order to cushion axial movements of the pipe section relative to the housing of the rotary drive.
  • the drilling device according to the invention can also be used so that the percussion drive of the inner rod is switched off, so that both rods are only rotated. This method of working will be used, for example, on sandy soils. Finally, it is also possible to make the rotary part of the rotary impact drive reversible for the inner linkage, so that the inner linkage can be rotated in the same direction or in the opposite direction to the outer linkage.
  • the inner rod 11 runs in the tubular outer rod 10, which is preferably also tubular.
  • Each of these rods consists of numerous pipes, the ends of which are either screwed directly to one another or connected to one another by means of sleeves.
  • the rear end of the outer linkage 10 is connected to a pipe section 12 which projects axially through the rotary drive 13.
  • the rotary drive 13 has a rotary motor 14 which drives a gear 15 via a gear.
  • the gear wheel 15 is supported with radial bearings 16 and axial bearings 17 in a housing 18 which surrounds the pipe section 12.
  • the gear 12 leads coaxially through the gear 15.
  • the pipe section 12 has radially projecting teeth 19 which fit into keyways 20 on the inside of the gear wheel 15, so that the gear wheel 15 is connected to the pipe section 12 in a rotationally fixed manner.
  • the splines 20 have a greater length than the teeth 19, so that there is a free space 21 in front of each spline tooth 19 and the pipe section 12 can be moved axially inside the gear 15.
  • the space in which the teeth 19 can move axially is limited laterally by two rings 22, 23 which surround the tube piece 12.
  • the front ring 23 rests on a support ring 24 which is accommodated in a cover 25 screwed onto the housing 18.
  • This cover 25 contains a spring device 26 made of several plate springs.
  • the rear end 27 of the tube piece 12 protruding from the housing 18 is designed as a radial impact transmission surface.
  • the rotary impact drive 28 is arranged, which is a hydraulic Impact device 29 and a rotary motor 30.
  • the striking device 29 strikes a rod 31 which is rotated by the rotary motor 30 via a gear 32.
  • the rod 31 protrudes axially through the gear 32 and the striker 29 strikes the rear end of this rod.
  • the front end of the rod 31 is connected to the rear rod 34 of the inner rod 11 via a sleeve 33.
  • This rod 34 is provided with a radially projecting ring collar 35, the end face 36 of which faces the end 27 of the pipe section 12.
  • the rotary drive 13 and the rotary impact drive 28 are mounted on a carriage 37 which can be moved along a guide 38 in the longitudinal direction of the linkages 10 and 11.
  • a feed device (not shown) drives the carriage 37 towards the borehole.
  • the rotary drive 13 is fixedly attached to the carriage 37.
  • the rotary impact drive 28, however, is displaceable in the longitudinal direction of the slide. This displacement takes place by means of an adjusting device 39, one end of which is attached to the slide 37 and the other end of which is connected to the rotary impact drive 2.8.
  • the actuator 39 is a piston-cylinder unit that can be operated to change the axial distance between the rotating device 13 and the rotary impact device 28.
  • the rotary impact device 28 is moved to the rotary drive 13 by actuating the adjusting device 39, so that the end face 36 is pressed firmly against the end 27. In this state, the strikes of the striking device 29 are transmitted from the inner linkage to the outer linkage. However, both linkages rotate independently of one another.
  • FIGS. 2 and 3 differs from that of Figure 1 only in that the end 27 'of the pipe section 15 and the end face 36' of the ring collar 35 are not flat, but have interlocking teeth 35 which have a rotationally fixed coupling between the rod 34 and the Pipe piece 35 cause when they are pressed axially against each other.
  • the rotary drive 13 is thus supported by the rotary motor 30 of the inner linkage. This results in a more even load distribution between the rotary drives.
  • Fig. 4 shows the state of the drill bits in which in the Figs. 1 and 2 shown mode of operation, are decoupled from each other in the inner linkage and outer linkage.
  • a ring drill bit 42 is fastened, in which the central inner drill bit 43 connected to the inner rod 11 is guided in a longitudinally displaceable manner. Flushing liquid is pumped through the channel 44 of the hollow inner rod 11 to the bottom of the borehole. The flushing liquid exits through the inner drill bit 43 and drives the drill material through lateral grooves of the inner drill bit into the space between the inner rod 11 and outer rod 10.
  • the diameter of the inner drill bit 43 is adapted to the inner diameter of the ring drill bit 42, so that the inner drill bit is centered in the ring drill bit.
  • the retebohrkrone 43 is retracted with respect to the ring bit 42nd
  • Both drill bits can also be arranged with their cutting elements in one plane. It is also possible to let the inner drill bit advance in relation to the ring drill bit without an impact coupling occurring.
  • Fig. 5 shows the state that the drill bits assume when the inner rod 11 is advanced so far that the annular shoulder 35 abuts the pipe section 12.
  • the inner drill bit 43 protrudes from the ring drill bit 42, but is still guided centrally by the latter.
  • the inner drill bit 43 strikes the borehole bottom 45 and works a relatively large area.
  • the ring core bit only has to machine that part of the bottom of the borehole that has not been covered by the inner core bit 43. The blows of the inner core bit already loosen part of the material lying in the area of the ring core bit.
