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 pin can according to the invention for axial fixation in a region having a flattening.
- the recess, the coupling jaw or the insertion channel of the recess has a corresponding in this case
- the invention does not exclude that a radial or axial fixation are transmitted via an additional groove / spring coupling, in which, for example, groove and tongue are part-arc-shaped and the groove is rotated in the spring when connecting the rod shots.
- 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. 2 is a detail view of a coupling pin according to the invention.
- Figure 3 shows two rod sections after insertion in the angular position.
- Fiq. 4 two rod sections after pivoting into the extended position;
- Figure 5 shows two rod sections of Figure 4 after pivoting in the extended position in another view ..;
- Figure 6 shows the ready clutch in an angular working position.
- Figure 7 shows an alternative embodiment of the coupling according to the invention with axially insertable coupling.
- FIG. 9 shows the embodiment of FIG. 8 in an angular position (plug-in angle);
- 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).
- Fig. 7 shows an embodiment according to the invention, in which one of the first
- Coupling part 20 located transverse web 26 with a frontal flattening 22 axially
- the transverse recess 28 has a non-cylindrical portion 23. Due to the frontal flattening 22 on the transverse web 26, the rod shanks must slide into the transverse recess 28 when the transverse web 26 is inserted are in a 90 ° -W ⁇ nkel to each other (plug angle)
- the circular cross-section in cross-section 28 ensures a secure hold of the crosspiece 26 in the transverse recess 28 for all other angles to the extended position
- the second coupling member 31 is an L-form ⁇ ges coupling jaw 30 on the coupling jaw 30 is in relation to the transverse recess
- the rod shot 4 axially rotated by 90 ° and then pushed along the axis of the rod shot in the end position of Figure 7, which is possible due to the flattening 32
- the two rod shots 4, 7 are in turn connected to each other, as soon as they leave the 90 ° -W ⁇ nkelloid because the geometry of the crosspiece 36 permits leaving the transverse recess 38 only when the flattening 32 is in the plane of the longitudinal web 34.
- the rod shots can be pivoted against each other, for example from the
