  • DETAILED DESCRIPTION OF THE INVENTION [0022] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but Is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
  • an exemplary embodiment of the present invention provides a borehole reaming cutter retention and fastening/locking system enabling field replacement of borehole reaming cutter assemblies utilized in infrastructure emplacement horizontal drilling (HDD) applications.
  • the borehole reaming cutter assembly retention/fastening system can withstand borehole drilling forces without the necessity of permanent welding, thereby allowing cutter interchangeability/repiacement in the field.
  • the borehole cutter retention assembly shape and design, coupled with the fastening/locking mechanism design, may be robust enough to replace permanent welding and may allow field cutter interchangeability and replacement.
  • the cutter retention system design and shape may spread the borehole drilling forces evenly across a large surface area.
  • This retention system may impart robust cutter assembly holding power, thereby relieving drilling stresses from the rear fastening/locking mechanism.
  • a rear dual fastening/locking mechanism may provide cutter assembly fastening/locking redundancy.
  • the cutter leg assembly is adapted to mate to the cutter leg receptacle and the fastening /locking mechanism may be integrally designed for proper retention without requiring weld attachment.
  • the machined male cutter assembly leg shape is adapted to mate to the machined female receptacle shape thereby equally spreading the loading forces circumferential!y. This may relieve borehole drilling stresses upon the rear fastening/locking mechanism, thereby not requiring physical welding attachment to offset these borehole drilling forces. This permits field interchangeability/replacement of borehole cutting assemblies.
  • a cutter retention system 10 may include a leg 12 for receiving a cutter 20 (see Figure 4), a receptacle 14 for receiving the leg 12 and a fastener 16 for connecting the leg 12 in the receptacle 14.
  • one end of the leg 12 may have threads mating with threads of the fastener 16.
  • the leg 12 may fit entirely inside of the receptacle 14.
  • a retainer 18 may be disposed between the fastener 16 and the receptacle 14.
  • the fastener 16 may fit into a recess 14-2 in the receptacle 14. The retainer 18 may help retain the fastener 16 on the leg 12.
  • the retainer 18 may be, for example, a washer, a lock washer, a star washer, or the like.
  • the receptacle 14 may have a hollow interior designed in a conical shape.
  • the leg 12 may have an exterior conical shape matching the hollow interior shape of the receptacle 14.
  • a space 22 may remain in between the leg 12 and the receptacle 14. Also, a space 24 may remain after the fastener 16 is secured to the threaded end of the leg 12. Further tightening of the fastener 16 may reduce the spaces 22, 24 and cause radial compression of the receptacle 14 against the leg 12. This radial compression force may help secure the cutter 20 inside the leg 12.
  • the receptacle 14 may include at least one locking mechanism 14-1 for receiving and rotationally locking the cutter 20.
  • the locking mechanism 14-1 may include a pair of ridges for mating with corresponding indents in the leg 12.
  • a locking mechanism 12-1 may have a radius of curvature, such as a radius of curvature of about .125.
  • the locking mechanism 12-1 may align with the locking mechanisms 14-1 of the receptacle 14 for securing the cutter 20.

Abstract

Un système de retenue et de fixation/verrouillage d'un outil de découpe d'alésage d'un trou de sonde permet le remplacement sur site d'ensembles d'outils de découpe d'alésage de trou de sonde, utilisés dans des applications de forage horizontal d'un emplacement infrastructurel (HDD). Le système de retenue/fixation d'un ensemble d'outil de découpe d'alésage d'un trou de sonde peut résister aux forces de forage de trou de sonde, sans avoir besoin de recourir à un soudage permanent, permettant ainsi une interchangeabilité/un remplacement de l'outil de découpe sur le terrain. La forme et la conception de l'ensemble de retenue d'un outil de découpe d'un trou de sonde, combinées à la conception du mécanisme de fixation/verrouillage, peuvent être suffisamment solides pour remplacer un soudage permanent et peuvent permettre une interchangeabilité et un remplacement de l'élément de découpe sur site. Les modèles et dispositifs actuels utilisent un soudage permanent des ensembles composants/éléments de découpe, nécessitant ainsi une construction et déconstruction du soudage en atelier pour permettre l'interchangeabilité et le remplacement des ensembles d'outils de découpe.
