Definitions

  • the present disclosure relates to an automated drill bit changing system for a mobile drill rig and a changing process.
  • Another problem of automated drill bit changing is the non-uniform geometry of the drill bit itself. When the bit rotates, a different surface is presented, making it difficult to have a form fitted device to grab onto the bit.

  • the drill bit changing system will be able to withstand all of the incident stresses while in standby and drilling operation. These stresses can range from those caused by the weight of the bit to those caused by vibration during drilling.
  • Alignment is another consideration. To ensure reliability, the drill bit needs to be in a guaranteed position to avoid cross threading a bit to the drill pipe. A cross thread will cause an equipment shutdown because of an inability to remove the drill bit.

As mentioned above, the system is designed based on existing drill rig components' structural robustness to compensate for dangerous conditions.

  • Bit storage holder 22 is arranged to hold a plurality of bits, for example, between 3-6 bits. However, due to space constraints, the bit storage system must not have a size that would interfere with the current drill tower due to rotation of the bit holder 22. Drill bit storage holder 22 must be able to rotate and index to proper position so the drill pipe can connect with a new bit. Accordingly, the drill bit storage holder is indexed by a slew drive 38. Slew drive 38 can be a worm gear mechanism actuated by a hydraulic motor capable of provide rotational actuation. Indexing of the slew drive can be controlled by control unit 16.
  • the slew drive indexes the carousel from one bit cup 28 to the next to allow the drill bit adaptor assemblies 24, 30 to be accessed.

  • bit adaptor has a necked down, round section 46, which is engaged by adaptor arm 40 to hold the adaptor/bit assembly so that the threaded joint between the adaptor and the drill string can be broken and a new adaptor/bit assembly can be added to the drill string.
