Definitions

  • This invention relates to an apparatus for percussive, long-hole and down-the- hole drilling operations.
  • Drilling rigs used in percussive, long-hole and down-the-hole (DTH) drilling operations require that drilling rods be added and removed from the drill string during drilling. It is advantageous to automate rod handling as it increases the safety and efficiency of the operation.

  • an electro-actuated magnet 100 with the pick and place mechanism 84 is advantageous as it provides a compact design with few moving parts. Additional advantage is secured by using the rotating magazine, which permits the rig to handle rods of different length and diameters, affording significant versatility to the drilling rig.
  • Proximity sensors may also be integrated into the rig to improve rod handling. The sensors can be used to sense the presence or absence of a rod at a specific position on the magazine.

Abstract

Le magasin est positionné dans un espace central à l'intérieur d'une enveloppe définie par la perforatrice de roches et le cadre sur lequel est monté la perforatrice de roches. Un mécanisme de prélèvement et de placement est positionné entre la perforatrice de roches et le magasin et manipule des tiges ajoutées et retirées du train de tiges de forage. Le cadre est monté pivotant sur une série de tables et de chariots qui permettent la rotation et la translation de la perforatrice autour et le long de trois axes mutuellement perpendiculaires pour orienter l'axe de forage par rapport à une face rocheuse.
