Definitions

  • the invention relates to a device for controlling a A drill pipe according to the preamble of claim 1.
  • Such a device is known from DE 41 04 992 C2.
  • this device there is an eccentric guide in the front area, d. H. in the first tube of the outer rod intended.
  • the drill string can be turned by turning this eccentric leadership can be brought into a position which is necessary or desired for the directional corrections if the drill head deviates from the intended one Direction.
  • the outer linkage is adjusted accordingly necessary amount rotated, which at the same time the eccentric guide turns the drill pipe in the new intended location. That way the desired course of the borehole is made and the previous one Borehole course to be corrected.
  • This device must also be used when the drill hole is straight a control take place.
  • the invention has for its object a device to control a drill pipe to create the straight Borehole management does not require a control process but only requires a correction if a deviation from the target rate is determined.
  • the eccentricity can be changed by an axial displacement of the outer linkage.
  • the axial displacement is converted into a rotary movement.
  • both the drill pipe in the control housing is eccentrically guided as well as the control housing in the The outer linkage is mounted eccentrically, the changes Guiding the drill pipe through an overlay of the two Eccentricities.
  • the control housing is for a straight borehole so arranged in the outer linkage that the eccentric Storage of the control housing in the outer linkage and the eccentric guidance of the drill pipe through the Overlay the control housing in such a way that the drill pipe is centered is arranged to the outer linkage.
  • the two eccentricities thus cancel each other out.
  • This device is suitable for controlling the drill pipe for all soil classes.
  • the device is suitable especially for bores where a straight line Borehole course is desired, such.
  • the drill is either in a starting pit or set up and aligned directly in the basement.
  • the drilling is first started in the position in which the drill pipe is arranged centrally to the outer pipe is. Only if there is a deviation from the straight borehole course the axial displacement of the Outer linkage.
  • a skid can be arranged on the outer linkage.
  • control housing there are recesses for flushing away available. So that these recesses do not go through coarser particles are added is in a further training the invention behind the drill bit one or more Wing provided. These wings are on the inside bore assigned to the outer linkage webs, which is a shredding ensure the larger drilling particles. A clogging of the Exceptions are no longer possible. A flushing removal is guaranteed at all times.
  • the control housing arranged is bores with the device according to the invention advantageously combined with the placement of empty pipes become.
  • FIG. 1 is the front part of a drill pipe 1 with an inner channel 2 for the rinse water supply and a drill bit 7 and an outer rod 3 in two different Positions shown.
  • the drill bit 7 with its outer diameter 8 arranged centrally to the outer linkage.
  • the lower Longitudinal section shows a position at which the drill bit 7 with its outer diameter 8 eccentric to the outer rod is arranged.
  • control housing 4 In the outer linkage 3 is a control housing 4 with a Guide groove 5 arranged.
  • the control housing 4 is through a spacer tube 9 with a fitting ring 10 in the outer linkage 3 held. Both the outer linkage 3 and that Control housing 4 has an eccentric bore. Thereby the control housing 4 in the outer linkage 3 is eccentric stored and the drill string 1 is in the control housing 4 eccentrically guided.
  • the control housing 4 In the upper longitudinal section 1, the control housing 4 is such in the outer linkage 3 arranged that the eccentric storage of the Control housing 4 in the outer linkage 3 and the eccentric Guiding the drill pipe 1 through the control housing 3 so overlay that the drill string 1 with the drill bit of 7 is arranged centrally to the outer linkage 3. By this arrangement becomes a straight hole when drilling achieved.
  • FIG. 1 A result of the axial displacement of the outer linkage 3 is shown in the lower longitudinal section of FIG. 1.
  • the outer linkage 3 is axial from the drill bit 7 to the right been postponed.
  • the drill pipe 1 is now arranged eccentrically to the outer linkage 3.
  • the outside diameter 8 of the cores 7 coincide in the lower part that of the outer linkage, while on the opposite Side the drill bit 7 accordingly opposite Projecting outer linkage.
  • control housing 4 In the control housing 4 are recesses 11 and 12 for the Rinsing removal provided. Are on the drill string 1 7 wings 14 and 15 arranged behind the drill bit. In the front The area of the outer linkage 3 is webs 16 and 17 intended. With this arrangement, during the drilling process larger drilling particles in the returned rinse water crushed. Clogging of the recesses 11 and 12 is no longer possible.
  • a skid 13 can be arranged on the outer linkage 3 be in soft rock or soil according to the invention Drilling control supported.
  • FIG. 4 shows the arrangement of the invention Drilling control on a drill carriage 20 out.
  • the rotating bracket 21 is via a carriage 25 with a gear 28 and a hydraulic motor 29 existing slewing gear connected.
  • a cylinder 26 with a piston 27 By means of a cylinder 26 with a piston 27 the outer linkage 3 by means of the rotatable bracket 21 move axially.
