Definitions

  • the invention relates to a device for the precise control of the drill pipe during the production of, in particular, overlay bores, the drill pipe carrying the drill head being influenced by the drilling machine in a rotating or rotating manner.
  • the object is achieved in that the drill rod is surrounded by an outer rod which has an eccentric guide comprising the drill rod at the end associated with the drill head and is rotatable.
  • the drill pipe is still used as an inner pipe for the transmission of pressure and torque and drills the entire drill diameter by rotating or rotating.
  • the outer rod encompasses the drill rod and holds the drilled borehole open when drilling in stable and especially in non-stable mountains.
  • this outer rod has the essential task of taking out the necessary measuring technology and at the same time also taking over the control of the drill pipe.
  • an eccentric guide is provided in the front area, ie in the first tube of the outer linkage, so that the inner linkage can be brought into the position that is necessary or desired by rotating this eccentric guide. This is achieved simply by rotating the outer tube accordingly by the necessary amount, which at the same time also rotates the eccentric guide, which thus brings the drill pipe into the new position provided.
  • the outer rod can be rotated from the mouth of the borehole, so that in this way, if the desired / actual deviations are determined accordingly, the course of the borehole can be corrected from the mouth of the borehole, which is particularly due to this It is possible that the outer rod is arranged unaffected by the rotation of the drill pipe.
  • the outer rod is not designed to rotate, so that the end of the outer rod protruding from the borehole mouth simply has to be rotated in order to make the necessary borehole course correction in the deepest part of the borehole.
  • the first tube of the outer linkage which has the guide, is at the same time designed to serve as a support for the measuring technology. This ensures an optimal measurement of the borehole course, precisely where the corrections are initiated or initiated.
  • the eccentric guide is formed by a ring in which the bore and recesses for conveying cuttings are introduced. The eccentricity of this hole or the entire guide can vary depending on the application. In order to be able to carry out an exchange here, if necessary, or to simplify repairs that become necessary, it is provided that the eccentric guide is designed as a ring detachably connected to the outer linkage.
  • This ring can be easily released since it is connected to the outer linkage by means of retaining and centering screws.
  • the retaining and centering screws ensure that the ring is also fixed in the predetermined position in the outer rod and thus always assumes the same or precisely provided position, since this is the only way to carry out the correct borehole course correction from the borehole mouth can.
  • the measuring technology can be optimally attached to the first tube of the outer rod if, as provided according to the invention, the measuring technology is integrated in the area of the guide into the first tube of the outer rod, specifically in a protective ring with recesses on the inside, which is let into the tube is arranged. In this way, the measuring technology can be brought close to the eccentric guide, which optimizes the evaluation of the respective results.
  • the necessary parts of the measuring technology can then be preassembled in the protective ring, so that the necessary work is considerably simplified. At the same time, precise assembly is ensured.
  • Figure 1 the standing in the borehole front area of the drill pipe in longitudinal section
  • Figure 2 - a prehead view in the cut area.
  • Figure 1 shows the usual drill pipe 1, which can either have an inner channel 2 or consists of solid material and which is encompassed by the outer rod 3.
  • the necessary contact pressure and the torque are transmitted via the drill pipe 1, the drill head forming the front end of the drill pipe 1 not being shown here.
  • the first tube 4 of the outer rod 3 is equipped at the end 5 facing the drilling head (not shown here) with both the measuring technique 6 and an eccentric guide 10.
  • the measuring technique 6 is accommodated in a protective ring 8 provided with a recess 7 or more recesses, this protective ring 8 being let into the outer rod 3.
  • the outer linkage 3 has a correspondingly deep groove.
  • Further measuring technology is accommodated in the area 6 ', the measuring technology being designed such that the inclination, the roll angle and the direction can be measured over 360 °. The direction is then influenced by the eccentric guide 10.
  • the eccentric guide 10 consists of a ring 11, which is shown in FIG. 2, in which an eccentric inner bore 12 is provided in this ring 11, through which or in which the drill pipe 1 is supported, and recesses 16 are provided for the removal of cuttings.
  • FIG. 2 illustrates the arrangement of the ring 11, that is to say for the eccentric guide 10 within the outer rod 3, the drill rod 1, which is guided in the eccentric guide 10 or the inner bore 12, being drawn out as a tube and dashed as a solid material is reproduced.
  • the drill pipe 1 and the outer pipe 3 are only connected to one another in the frame of the guide 10 with frictional engagement.
  • the outer rod 3 thus does not rotate with the drill rod 1, but remains in the intended position while the drill rod 1 rotates therein.
  • the friction in the area of the guide 10 is otherwise not sufficient to take the outer linkage 3 with it. So that the drill pipe 1 is guided by the eccentricity of the guide 10 exactly in the direction that it needs for a perfect course of the borehole.
  • the outer rod 3 is rotated by a corresponding amount.
  • the drill pipe 1 thus automatically changes its drilling direction and the course of the drill hole can be changed and corrected as provided.
  • the outer pipe 3 remains in this position until a further correction should be necessary.
  • small changes can also be made by turning the outer linkage 3, so that one can certainly speak of fine adjustment.

Abstract

Pour guider avec précision le train de tiges de forage (1), on utililse un dispositif dans lequel le train de tiges de forage servant à la transmission de l'effort de poussée et du couple est entouré d'un train de tiges extérieur (3) posé sans serrage. Au voisinage de la tête de forage, ce train de tiges extérieur dispose d'un guidage (10) excentrique dans lequel est guidé le train de tiges de forage. En tournant le train de tiges extérieur il est donc possible d'effectuer n'importe quelle correction de direction du trou de forage, cela se faisant en règle générale depuis la bouche du trou de forage, en tournant simplement le train de tiges depuis la bouche. Pour déterminer l'orientation du trou de forage, on détermine l'inclinaison longitudinale, et la direction du train de tiges.
