Definitions

  • the invention is based on the object of being able to recognize wear, in particular in the form of abrasion, in a simple manner on a drill string section.
  • the main idea of the invention is to provide a marking on the outside of a section of a drill string which is used to drill a hole in the ground, the change of which enables a conclusion to be drawn about abrasion during use.
  • abrasion is not limited to a single application, but when a drill string section is used several times, the change in the marking can provide an indication of the abrasion throughout the use.
  • a marking is advantageously used which enables observation with the naked eye and / or a change in the marking with the naked eye.
  • the invention provides a drill string section of a drill string for drilling in the ground.
  • At least one marking is arranged on the outside of the drill string section, by means of which an abrasion on the outside of the drill string section can be recognized.
  • This enables a simple configuration of a drill string section, a change in the marking allowing conclusions to be drawn about the abrasion and can be designed in such a way that a change is recognized from which, for example, the risk of the drill string section breaking could occur. If such a change is recognized, the drill string section can be renewed in order to avoid breakage of the drill string section and thus possibly loss of part of the drill string.
  • the marking can advantageously be designed in such a way that the change can be clearly seen with the naked eye, in particular in that the marking disappears or is less and less recognizable.
  • drill string section thus encompasses any section of the drill string, a front section of the drill string, in particular the drill head or a drill string section adjacent to the drill head, being preferred.
  • a drill string section can also be a rod section.
  • soil in the sense of the present description includes in particular any type of existing or to be created, preferably at least partially horizontal, channels or bores in a body, in particular earth channels including earth bores, rock bores or earth pipes as well as underground or above-ground pipelines and water channels can be manufactured or pulled in using an appropriate earth drilling device.
  • outside in the sense of the description includes an outer region of the drill string section that can come into contact with the ground.
  • the outside thus comprises an exposed area of the drill string section which, when used correctly, usually comes into contact with the ground and may be subject to abrasion.
  • the outside can form a partial section of a cross section of the drill string section, which can in particular be configured in an otherwise customary manner and on which at least one marking is arranged or formed.
  • the outside can be an outer surface of the drill string section in the usual way.
  • marking in the sense of the description encompasses a structural configuration which is arranged on the outside of the drill string section.
  • the marking can be attached to the outside and / or introduced into the outside.
  • the marking can be a change in the surface of the outside of the drill string section, which is, in particular, non-releasably applied and / or applied to the surface of the outside. Insofar as there is talk of introducing or applying the marking on the outside of the drill string section, this means in particular that the outside of the drill string section itself can be changed or modified in order to create the marking.
  • a further element can be provided on the drill string section, which forms the marking, but the marking is preferably formed by changing the surface of the outside of the drill string section compared to the unchanged surface of the outside on the drill string section.
  • the marking is preferably formed by changing the surface of the outside of the drill string section compared to the unchanged surface of the outside on the drill string section.
  • the marking can be a recess made in the outside of the drill string section, which can be formed, for example, by milling, turning or in some other way, in particular mechanically.
  • a marking in the sense of the description is therefore preferably a depression arranged on the outside of the drill string section, which preferably has an extension in the circumferential direction of the drill string section, at least in sections.
  • the depression can in particular be formed linearly along at least part of the circumference of the drill string section.
  • the depression can be designed as a notch.
  • the depression can be symmetrical to its base, at least in sections along its extent, i.e. the lowest point opposite the outside of the drill string section. An asymmetry with respect to the base of the depression is possible at least in sections.
  • the bottom of the recess can be designed with a radius to avoid notching.
  • a tapering bottom of the recess, which can also be present in sections, is not excluded.
  • the marking is designed at least in sections as a depression and at least in sections along the cross section, the smallest dimension of the "depth", i.e. the bottom of the recess corresponds to a minimum diameter of a worn drill string section. If abrasion occurs to the bottom of such a deep depression, i.e. the marking is almost no longer recognizable, so the minimum diameter of a worn drill string section has been reached. Until the minimum diameter is reached, which is recognized by the fact that the marking at least partially disappears but is still present, the risk of the corresponding drill string section breaking can be virtually ruled out. If the minimum diameter has been reached and the marking is therefore almost no longer recognizable, the drill string section can be renewed in order to avoid breakage of the drill string section and thus possibly the (partial) loss of the drill string.
  • a marking designed as a depression on the outside of the drill string section to be considered provides the advantage that there is a marking precisely in the material, the abrasion and the associated wear itself should be considered.
  • the inventors have recognized that although a marking designed as a depression can bring about a "weakening" of the material of the drill string section, the supposed weakening provides a decisive advantage with which it is possible to focus in particular on the minimum diameter of the drill string section that has not yet been reached, as long as the marking can be recognized.
  • Markings in particular depressions, can be assigned to different degrees of abrasion or wear. For example, depressions of different depths can indicate that a certain abrasion has already occurred on the drill string section, but - where at least one marking of greater depth can still be recognized - the abrasion is still in the uncritical range.
  • a marking designed as a depression can have a depth which can be dependent on the material of the outside or the coating or coating of the outside of the drill string section.
  • a marking designed as a depression usually has a depth which is less than 5 mm, preferably less than 4 mm, further preferably less than 3 mm, particularly preferably less than 2 mm, particularly preferably less than 1 mm, very particularly preferably less than 0 , 8mm and particularly preferably less than 0.5mm.
  • Markings designed as depressions can have a depth that can lie essentially by 0.5 mm, essentially by 0.3 mm and essentially by 0.15 mm.
  • the naming of a numerical value includes not only the actual numerical value, but also - in order to take into account manufacturing tolerances in particular - a range around the specific numerical value that can be +/- 15%, preferably +/- 10%, of the specified numerical value can.
  • the marking extends completely around the circumference of the drill string section.
  • the marking can be made closed around the circumference of the drill string section. In this way, it can be achieved that, in particular when the marking is formed uniformly around the circumference of the drill string section, an abrasion detection is possible in which the entire circumference of the drill string section can be detected. In particular, in the event of an uneven loading of the drill string section, which leads to a non-uniform, different abrasion along the circumference of the drill string section, the abrasion can nevertheless be recognized by considering the entire circumference.
  • a marking formed along the entire circumference of the drill string section can in particular be arranged in a closed circle around the longitudinal axis of the drill string section.
  • the circular shape can in particular essentially have an angle of 90 ° to the longitudinal axis of the drill string section. Deviations of 90 ° are possible. Shapes other than a circular shape can also result, for example an elliptical shape.
  • a marking is also possible for a marking to be formed only in sections along the entire circumference of the drill string section and for there to be no marking between the sections. This can further reduce a supposed weakening.
  • the marking can be made spirally in the circumferential direction of the drill string section.
  • the depth of the circumferential spiral marking can change, for example, in its course.
  • a spiral circumferential marking in the direction of the longitudinal axis of the drill string section can be made larger, in particular continuously, in a region (for example from 0 mm to 0.5 mm depth) in order to recognize different degrees of wear.
  • the depth of the circumferentially spiral-shaped marking in the direction of the longitudinal axis of the drill string section can (again) decrease to, for example, 0 mm.
  • a circumferentially spiral-shaped marking can thus be provided, which initially increases in depth in the direction of the longitudinal axis of the drill string section and decreases again in the further course in the direction of the longitudinal axis.
  • Different start and end values of the spiral marking are possible.
  • a symmetrical arrangement of the circumferential spiral marking with regard to the depth thereof can offer the advantage that a control function with regard to the uniform abrasion is possible.
  • Different degrees of abrasion can be determined by means of a marking that changes along its extent.
  • identically designed markings are possible on the drill string section in order to effect a control function.
  • the identically designed markings can be present at different angular positions with respect to the longitudinal axis of the drill string section.
  • the identically designed markings can alternatively or additionally be spaced apart from one another with regard to their position in the direction of the longitudinal axis.
  • the extent of a plurality of markings can be different or the same along the circumferential direction of the drill string section for the markings.
  • markings of the same depth can have a different extent in the circumferential direction.
  • differently designed markings different depths have an essentially identical extension in the circumferential direction.
  • a pattern can be created using the marking or markings are available, the appearance of which is optimized for the detection of a change. Symmetry with respect to an axis along a circumference can be helpful for recognizing a change in the marking or markings.
  • the marking or the markings can be rounded in the longitudinal extent radially to the longitudinal axis of the drill string section. With this shape, notch effects can be avoided or at least reduced.
  • the invention also provides an earth drilling device with a drill string, as described in particular above.
  • the earth boring device furthermore has a drive which is designed to introduce a drill string having the drill string section into the ground.
  • the invention also provides use of a drill string section for drilling in the ground using a mark on the outside of the drill string section by means of which abrasion can be detected.
  • ram boring device or "earth rocket”, which is used essentially synonymously with the “ram boring device”, includes, in the sense of the description, a self-propelled impact device which works to displace the earth and can strike a pipe or pipe into the ground.
  • ram boring device includes both earth displacement devices in which the drill head tip is firmly connected to the housing and ram boring devices with axially displaceable drill head tip which is displaceable independently of the housing.
  • the drill head tip can in particular be a chisel.
  • a ram boring device can be both a one-stroke device and a two-stroke device. In the case of a two-stroke device, the percussion piston first strikes the drill head tip, which leads in the first bar. The piston strikes the housing in the second cycle.
  • more than one marking can be arranged on the drill string section.
  • the markings can preferably be in different configurations in order to be able to recognize a degree of abrasion by means of a marking.
  • the markings can differ in particular in terms of their type, position, dimension and / or orientation with which they are arranged on the outside of the drill string section.
  • the marking can have different depths.
  • depth encompasses the extent of the depression in a direction radial to the longitudinal direction of the drill string section.
  • two or more degrees - depending on the number of total markings - can be recognized by providing several, for example two, markings with different depths.
  • markings which have a different depth, is still visible or is no longer visible due to the abrasion on the drill string section during the operations or after the operations when the drill string section is examined by a user, can be concluded on the degree of wear of the drill string section without the need for expensive measuring instruments. It is therefore not only possible to decide whether the drill string section is approaching a possible service life section, but rather what degree of abrasion or wear is present, whereby not only the end of life, but also degrees in between, can be recognized.
  • the markings can have different widths, for example in that the markings are present on the outside of the drill string section as V-shaped depressions or as rounded depressions with different slopes of the sides - in order to form the different widths. Increasing wear due to the continuous use of the drill string section also reduces the width of the markings.
  • a preferred embodiment has markings of different depths and / or widths, wherein widths and / or depths can be selected such that the different ones Markings can indicate a different degree of wear of the drill string section, regardless of which marking is still recognizable - or no longer recognizable.
  • a preferred arrangement of these, in particular uniformly, graduated markings can be carried out as follows: The markings on the drill string section are arranged transversely, in particular orthogonally, to the direction of the longitudinal axis of the drill string section, preferably in mirror image with respect to an axis transverse to the longitudinal direction of the drill string section. You can start with the mark or markings with the greatest depth, which can be 0.5 mm, for example. Further markings, for example 0.3 mm and 0.15 mm deep, can follow the drill head towards or away from it, starting from the mark or markings with the greatest depth.
  • Fig. 1 shows a drill string section 1 designed as a ram boring device, with a housing 2, within which a (not visible) percussion piston is arranged.
  • the percussion piston is supplied with compressed air via a compressed air hose 4 in order to be able to perform reciprocating movements within the housing 2.
  • the percussion piston can be reversed in such a way that it either strikes the front area of the ram boring device in order to drive the ram boring device with the drill head 3 ahead through the soil, or in such a way that it hits the rear area of the ram boring device in order to drive it backwards.
  • the drill string section 1 marks 5, 6, 7 are arranged on the housing 2 of the ram boring device.
  • the markings 5, 6 7 make it possible to recognize different degrees of abrasion on the housing 2.
  • the abrasion that occurs on the housing 2 and increases over time arises from the resistance of the soil during the drilling progress.
  • Fig. 2 shows the section Y greatly enlarged Fig. 1 .
  • three depressions 7 designed as grooves are screwed in. These outer recesses 7 have a screw-in depth of 0.15 mm.
  • the material on the outside of the housing 2 is removed by the abrasion to such an extent that the depressions 7 are initially hardly or no longer recognizable. This indicates the start of wear of the drill string section 1 or the housing 2 and enables a first estimate of when the housing 2 will be worn out to such an extent that it has to be replaced.
  • Fig. 3 shows an example of a further possible embodiment of the markings 5, 6, 7 for recognizing the wear of a housing 2.
  • this embodiment instead of circumferential depressions 5, 6, 7, depressions 10, 11, 12, which extend only over a partial area of the circumference, milled into the housing 2 with different depths.
