Definitions

  • a roller reamer is used in conjunction with a drill bit and a drilling string, whereby the drilling string is adapted to rotate both the drill bit and a plurality of roller reamers attached to the drilling string.
  • a roller reamer is used in the drilling process for the purpose of enlarging the diameter of the bore hole being drilled, compacting and cleaning the walls of the bore hole and stabilising the drilling string so that it is central to the bore hole and minimises the possibility of drilling at an incorrect angle.
  • roller reamer requires a quick, efficient and reliable method of attachment to the reamer body.
  • the roller reamer should also be designed to reduce the number of positions where excessive stresses can result in catastrophic failure. As some degree of failure is inevitable, due to the nature of the operating conditions and function of roller reamers, a quick method of attaching and detaching the reamer needs to be employed. This would increase efficiency and ensure that the drilling process is not halted.
  • roller reamer includes a lubricant chamber adapted to prevent contact between the roller and the shaft and prevent debris from the reaming process from entering an aperture between said roller and said shaft.
  • roller reamer 14 attached to a reamer body 12 at one end.
  • the means of attachment comprises an attachment block 21, adapted to be contained in the attachment recess 20 and secured in position by a bolt 26.
  • the bolt 26 is adapted to be retained in position by the bolt recess 28. Due to the extreme operating conditions, roller reamers are typically subject to high levels of wear and deterioration. Therefore, in order to ensure a high rate of reaming, it is important to keep the roller reamer in use in an effective working condition for as long as possible.

Abstract

L'invention concerne un appareil d'alésage de trous de sonde caractérisé en ce qu'il contient un corps d'aléseur comprenant une pluralité d'évidements, chaque évidement recevant un aléseur à cylindre respectifs, ladite pluralité d'aléseurs à cylindre étant adaptée pour se fixer audit corps aléseur de manière circonférentielle et espacée. Chacun des évidements situés sur le corps d'aléseur comporte un évidement de fixation pour corps aléseur permettant à l'aléseur à cylindre de circuler sans entraves et un évidement pour aléseur à cylindre pouvant se fixer au corps aléseur aux extrémités avant et arrière de l'aléseur à cylindre, ledit évidement de fixation de corps d'aléseur pour ledit aléseur à cylindre à fixer au corps d'aléseur aux extrémités avant et arrière de l'aléseur à cylindre comprenant un bloc de fixation adapté pour se loger dans l'évidement de fixation de corps aléseur et un moyen de fixation adapté pour se loger dans l'évidement de fixation de corps d'aléseur. Le procédé de réception dudit bloc de fixation et dudit moyen de fixation dans ledit évidement de fixation de corps d'aléseur est caractérisé par un ajustement à faible serrage, sous forme d'un ajustement conique de positionnement.
