Definitions

  • This disclosure relates to a hydraulic boom for drilling holes, including a supporting assemblage, a swingable boom member supported by said supporting assemblage, a cradle member hingedly supported on one end of said boom member and having a feed member, slidably supporting a drill and power and control means for actuating and controlling the movement of the movable parts of the hydraulic boom and the drill.
  • the hydraulic boom arrangement provides for powered adjustment of the cradle member about vfive pivot points relative to the supporting assemblage. The adjustment about two of the pivot points is interrelated by a closed hydraulic servo arrangement.
  • This invention relates to a hydraulic boom particularly for blast hole drilling methods for mining and tunneling.
  • One of the requirements for hydraulic booms of this type is to reduce the so-called blind spots or those areas of a surface, which cannot be correctly reached by a boom, to a minimum.
  • An object of this invention is to provide a highly versatile hydraulic boom, simple in structure and reliable in operation which will be able practically to eliminate the so-called blind spots and will be able to cover a drilling hole pattern of any kind and which will reduce the number of steering or setting operations and the time and effort for reaching a drilling spot to a minimum.

  • a vertical pin 4 is pivotally supported for rotation.
  • one or more hydraulic cylinders 5 (FIGS. 1 and 6).
  • hydraulic cylinder 5 is pivoted to a part of the jumbo 3, and its attendant piston 5' is pivotally connected to a lug of the connecting group 4a in a point offset with respect to said pin 4.
  • Supported by the pin 4 is a sleeve 6 on which a hydraulic motor 7' which actuates a worm screw 7 is supported.
  • Journalled in the axial bore' of the sleeve 6 and coaxial therewith is a shaft 8 on which a gear 9 is keyed.
  • the shaft 8 defines a second pivot means having an axis of rotation perpendicular to the axis of rotation defined by said first pivot means 4.
  • the gear 9 meshes with the worm 7 and is driven thereby in rotation also through a full circle of 360 in either direction.
  • a fork member 10 In rigid relation with the shaft 8 is a fork member 10 which, through a pivot connection 11, pivotally carries the boom 12 proper and pivotally carries at a point 13 a hydraulic cylinder 14 controlling the swinging of said boom 12.
  • the pivot connection 11 defines a third pivot means having an axis of rotation perpendicular to the axis of rotation of the shaft 8.
  • the boom 12 may have a fixed length, however in more sophisticated embodiments, such as the illustrated one, the boom 12 can be fitted with a power cylinder 15 so as to permit an extension and retraction of the boom member.
  • Pivoted in 24 at the free end of the boom member 12 is a short arm 16 which bears the feed unit.
  • the feed unit may be of any known type and is briefly described hereinafter so as to facilitate the understanding of the operability of the hydraulic boom of this invention.
