  • Patent number: 9074455
    Abstract: The present disclosure provides drilling and tripping equipment packages and control schemes and methods using two or more lifting systems that operate simultaneously and continuously in a synchronized manner such that the feeding of tubular into or out of a well bore is achieved with continuous or near continuous movement, without the need for periodic interruptions. The drilling and tripping equipment packages and control schemes are also able to rotate the tubular in the well bore with continuous speed and torque sufficient for both drilling and back-reaming operations. The drilling and tripping equipment package and control scheme is additionally able to circulate drilling fluid into the internal bore of the tubular with sufficient pressure and flow to facilitate both drilling and back-reaming operations, with minimal interruption to circulation.

    Abstract: A vehicle typified by a front-end loader is provided with a driver's cab that pivots up and down along a long pivot arm. This gives both high elevation for better visibility and low profile, e.g. for travelling or getting into low overhead places. The long pivot arm provides a lot of vertical adjustability for the cab, with relatively little tilting. The tilting that does occur may be accommodated by also adjusting the back rest of the operator. A system for pivotally attaching the cab roof is also shown. In one variation shown, the cab is mounted transversally, i.e. sideways to the normal travel direction of the vehicle; in another, the cab is oriented longitudinally. Preferably most or all of the shell of the cab is stationary and only the operator's station part thereof is vertically adjusted.

  • Patent number: 4256186
    Abstract: An operator cab and drilling assembly for a roof drilling and bolting device. The cab comprises a floor and a canopy having extensible hydraulic means for adjusting the distance between the cab floor and at least the front edge of the canopy. A horizontal rail extends along the entire length of the front edge of the floor and is spaced therefrom. A roof bolting and drilling apparatus slidably engages the horizontal rail. The rail is mounted by swinging arms to always be parallel to the cab floor.

  • Patent number: 4250975
    Abstract: A system for mounting two operator cabs to a vehicle chassis for transverse extension. At least one large tube is mounted to the vehicle with its axis pointed in the direction of the operator cab movement. Two smaller tubes of different diameters telescopically engage the large tube and each other and project at opposite ends of the large tube. A bushing is fixed in the opening of the large tube from which the smallest tube extends. Two cab brackets slidably engage the outer surface of the large tube. An outer edge of each cab bracket is fixed relative to one of the smaller tubes which is a cantilever support therefor when the cab is extended outwardly of the length of the large tube. The cabs are slidably mounted to the cab brackets for vertical movement relative thereto.

  • Patent number: 4210213
    Abstract: A Kelly Bushing Guard is comprised of an outer protective guarding shell which coverably mounts on the kelly bushing portion of a drilling apparatus. The outer shell is comprised of an upper smaller shell section which is mountable on the kelly bushing itself, there being provided an upper opening through the upper shell portion allowing the passage of the kelly therethrough. A lower shell section is integrally attached to the upper shell section, the lower shell section coverably registering with and guarding the rotary table portion of a well drilling apparatus. An improved cushioned mounting is provided which can be in the form of a plurality of pliable rubberized rings. The larger lower shell section provides a free space under the upper shell section which free space allows the kelly bushing to freely rotate therewithin.

  • Patent number: 4116287
    Abstract: A well drilling assembly including a platform adapted to support a person while drilling a well therebeneath through an opening in the platform includes a clamp assembly carried by the platform and mounted for rotation with respect thereto. The clamp assembly includes a pair of open jaws disposed in confronting relatively movable relation and with respect to each other for engaging and for readily releasing a drilling stem so as to be able to support a column of drilling sections as new sections are added and also to permit the clamp to rotate while the drilling sections are rotated at a position supported by the clamp to hold the sections in spaced relation from the bottom of the hole being drilled. The method of drilling includes manipulations involved in supporting the sections of pipe spaced from the bottom of the drilled hole while flooding water through the pipe to flush out the opening and also to permit the pipe to be rotatably driven while so held without exerting manual lifting force on the pipe.

  • Patent number: 4108253
    Abstract: A drill boom is connected at its rear end portion to a mobile body and supports at its front end portion a drill pot for rotating a drill steel. The drill boom raises the drill pot along a predetermined straight-line path to advance the rotating drill steel into the mine roof to form a bore hole for insertion of a roof bolt assembly. An operator's compartment is slidably mounted on the front end of the mobile body laterally of the drill boom. A hydraulic cylinder positioned on the mobile body raises the operator's compartment along a plane aligned with the plane of movement of the drill pot. A protective canopy overlies and is movable with the operator's compartment. A drill steel guide is secured to the canopy and includes movable guide portions that extend into surrounding relation with the drill steel. The drill steel guide is elevated with the canopy to a position adjacent the mine roof.
