Definitions

  • This method relates to a drill bit assembly, where a hole is drilled with several drill bits detachable from one another and where, by means of a component transmitting the turning motion, the bit that drills the inner hole portion rotates the ring bit that drills the outer hole portion.
  • the sequence of their opening can be made to follow as wanted in arranging the coupling that is to be opened at first more easily opened with respect to its oblique angle on rotating the bit in its opening direction.
  • Fig. 1 shows a ring bit
  • Fig. 2 shows an inner bit used in combination with the ring bit.
  • Fig. 3 shows another inner bit and ring bit combination.
  • Fig. 4 shows a third inner bit and ring bit combination.
  • Figure 1 shows extensions 3 and 4 in three rows on the inner ring bit surface and similarly placed on the inner circumference. Most suitably the extensions are arranged with equal spacings on three spots. In the lower part of the ring bit there are special elevations 5, three of them, too, placed at the extensions. The upper surface of elevations 5 has a level portion and a slanting portion 10.
  • Figure 2 shows a corresponding inner bit with grooves 7 and 8 for ring bit extensions 3 and 4. There are grooves also with equal spacings in three spots on the inner bit outer surface. Further, there are in the bit three axial grooves 9 along which the ring bit extensions can shift over by ring bit assembly onto the inner bit.
  • the ring bit With the ring bit in proper place, the ring bit is turned so that extensions 3 and 4 enter the corresponding grooves 7 and 8. Also the lower edg elevation 5 enters the matching hollow 6. When turnig is carried out to its end, the ring bit is tightened with respect to the inner bit by the slanting surface of elevation 5 so that the backlash between the extensions is eliminated.
  • Figure 3 shows another embodiment, where elevation 5 is on the inner surface of ring bit 1'.
  • the counter faces d,d' are tightened so as to be free of backlash.
  • the upper surface of elevation 5 is divided into a level portion 13 and a slanting portion 10.
  • the oblique angle is ⁇ and its value most suitably between 4° - 30°.
  • a big angle reduces the tightening effect and facilititates also the falling of ring bit off its locking when the inner ring is not being rotated.
  • the most advantageous oblique angles are between 5° - 10°. Drill waste is conveyed through the inner bit along the channel marked with broken lines.
  • FIG 4 there is still one version, where the counter- faces are marked with references e,e'.
  • the drill waste is conveyed along the same channel 9 as where the axial motion is carried out by elevation 5 in the detaching and fitting stage of the bits.
  • Level portion 13 of the elevation secures the ring bit in place on the inner bit when the bit assembly is upright on starting drilling, for instance.
  • the elevation 5 itself, by its axial locking effect, prevents the ring bit and then also the protecting tube 12 from moving moving farther than inner but if drilling is done downward into soft ground.
  • the inner bit turning motion in proper direction secures the function of elevation 5 as well as the functions of locking and elimination of backlash.
  • the elevation can be either in the ring bit or in the inner bit and, correspondingly, the hollows 6,9,11 in the ring bit or in the inner bit.
  • the bit opening arrangement can be adjusted by means of slanting surface 10 and angle .
  • the coupling opens in which a greater angle is used and the last to open is the coupling with a smaller angle.
  • the coupling with the smaller angle gets more effectively tightened and, accordingly, it is the last to open.

Abstract

La présente invention concerne un ensemble trépan permettant de forer un trou dans un sol ou une roche comprenant un trépan interne (2) mis en mouvement de rotation au moyen d'un ensemble de forage et une couronne de trépan (1) pouvant être verrouillée et libérée du trépan interne. Le verrouillage entre les trépans peut être ouvert et le trépan interne dégagé ou trou la couronne de trépan restant dans le trou, une surface située entre les trépans transmettant une force axiale dans le sens du forage du trépan interne à la couronne de trépan. Le système, par exemple, un évidement (11) ou une partie saillante correspondante (5), présente une contre-surface inclinée destinée à éliminer les effets de rebond pendant les opérations de forage et à produits un resserrage ininterrompu des surfaces de transmission des forces axiales des trépans. Les contre-surfaces des éléments considérés (l'évidement ou la partie saillante) empêchant tout ou partie de la commande de trépan et/ou du tube de protection (12) d'aller plus loin que le trépan intérieur.
