Definitions

  • the invention relates to a rod coupling, as used for connecting rods in underground horizontal drilling and trenchless laying or replacement of pipes (hereinafter horizontal drilling).
  • the linkage consists of several boom sections, which are gradually connected to each other or separated from each other according to the drilling progress.
  • the single section has a limited length and must be very short, especially when drilling from a short excavation, such as a shaft, inspection shaft or manhole, from happening.
  • Such shafts may have diameters of sometimes less than one meter.
  • a linkage coupling in which a first coupling point is inserted into a second coupling point.
  • the coupling point of the linkage is under a worm of about 60 ° relative to the longitudinal axis of the In this case, hemispherical projections of the first coupling part engage in recesses of the second coupling part.
  • connection is secured by a securing element in the form of a securing sleeve
  • a peg-like projection is brought over the groove into a bearing bore of the slot by pivoting of the following linkage section This is brought from the angled insertion position in the extended position and then coaxially with the preceding section of the rod The axial fixation is ensured only in this position, while lateral fixation is carried out by the side walls of the barge shoots Alternatively, the zapfenformige projection is laterally in the Sc In order that the pin does not fall out of the slot, a lateral fixation is provided by protruding side walls of the rod shots, which prevent the coupling from falling apart in the extended position
  • a coupling is described, are plugged together in the rod shots by connecting corresponding ends of the rod shots by a parallel displacement of the Gestebeschußachsen, wherein the rod assembly axes when parallel displacement an angle of ⁇ ⁇ 180 ° to each other.
  • a first rod section in this case has a pin which engages in a corresponding recess of a second rod section. Falling out of the pin is also prevented by an undercut, which engages after Einrotieren in a shoulder on the subsequent rod section or a
  • the object of the invention is to provide a simplified or more widely applicable linkage coupling for horizontal drilling.
  • the invention is based on the idea of providing a drill pipe with a plug-in coupling, in which the geometric shape of a transverse web permits insertion in a certain space of widening (insertion angle), i. in a defined angular position outside the working angle allows and at the same time a fixation over a wide
  • Angle range ensured in a corresponding receptacle.
  • the insertion may be possible both in the radial direction and in the axial direction.
  • crosspiece and / or recess may differ in their geometry from a circular cross-section.
  • the transverse web can be designed, for example, as a pin to be inserted laterally into the recess, as described in DE 100 65 533, but then have one or more shoulders.
  • the corresponding recess allows in a certain angular position of the rod sections to each other a lateral insertion of the pin (insertion angle) by recess and pins have a flattening or in a circular segment of the recess one or more corresponding grooves are provided for the shoulders. Outside this angular position, i. At working angle, the shoulders of the pin ensure radial fixation of the rod sections with respect to each other by locating the recess outside of the socket
  • the transverse web can also be provided as an axially inserted into the recess coupling part.

  • the coupling according to the invention can be used with different types of linkage and also with a support device for redirecting the pushing or pulling forces from the drive axle into the channel axis.
  • the linkage may independently be a circular arc segment on both sides, i. concave / concave or concave / convex, be designed to image the shape of various support means or to be operated in different Kurven ⁇ richtu ⁇ gen.

  • Fig. 10 shows the embodiment of Fig. 8 in an extended position.
  • the coupling members each have a coupling surface 3 and 4, wherein the coupling surface 3 has a not completely cylindrical pin 6, which is provided with a recess 8 of the coupling surface 4th corresponds.
  • the pin 6 has at its end two shoulders 12, 14 oriented vertically to the longitudinal axis of the bar.
  • the recess 8 has a non-cylindrical shape (see section 13b) and a corresponding to the shoulders 12, 14 groove 16 which is oriented horizontally with respect to the linkage axis.
  • the orientation of the shoulders 12, 14 and the flats 13a and 13b and the groove 16 causes the rod sections when joining at right angles (insertion angle) must be arranged to each other to bring the shoulder 12 in alignment with the groove 16 (see. Position in Fig. 3). If flattening 13a and 13b are aligned (insertion angle), the pin 6 can be inserted into the recess 8. As soon as the rod sections leave their right-angled relative position, the shoulders 12, 14 secure the pin 6 in the recess 8 at all angles up to the extended position via an undercut 19 (see FIG. 4) or on the opposite side of the recess 8 escape (not shown).
