  • Patent number: 10895111
    Abstract: A guide for a top drive unit includes a lower track member connected to a lower mast section and an upper track member connected to an upper mast section and telescoped with the lower track section. A slider is slidably positioned about the upper track member so the slider is movable along the upper track member. The slider has a lateral cross-sectional profile substantially the same size and shape as a lateral cross-sectional profile of the lower track member. The skate is slidably positioned about the lower track member to be movable along the lower track member and onto the slider. The skate travels along the upper track member via the slider. The skate is connectable to a top drive unit so the top drive unit is movable along the lower track member and the upper track member.

  • Patent number: 6257349
    Abstract: A top head rotary drive and mast assembly for drilling which is adapted to be readily mounted on a derrick of a conventional truck, crawler or other vehicle so as to be movable from a stored position adjacent the derrick to a deployed position spaced from the derrick for drilling. The mast is adapted to be pivotally connected by at least one upper support arm to the derrick of the vehicle. The deployment and retraction of the mast and the top head rotary drive relative to the derrick are accomplished utilizing either a control device for moving a holding plate which is movable along the mast and to which the top head rotary drive is mounted or by separate lifting device. The invention is also directed to a combination top head drive and mast assembly and drilling rig and method for their use.

  • Patent number: 6234719
    Abstract: A method in or relating to piling of e.g. tubular bases which are placed and, possibly, casted within a hole drilled out in earth mass in ground or the like is described. One uses a generally known drilling rig, in which a bit is assigned a drilling hammer, and drills a hold having a depth approximately corresponding to the base pipe. If there exists a need for piling, the drill string is swung aside, away from the hole, after having been pulled up, and one or, possibly, a plurality of piles is/are rammed down with a starting point at the bottom level of the bore hole. In order to drive the pile(s) down, the drilling hammer of the drilling rig is used.

  • Patent number: 6227306
    Abstract: A pipe gripping device is taught which is useful for moving pipe into and/or out of a well. The pipe gripping device includes a first set of slips for holding a pipe in a pipe light condition and a second set of slips for holding a pipe in a pipe heavy condition. The second set of slips are actuatable independently from the first set of slips. The pipe gripping device can include a slip moving system which prevents the slip carrier blocks from being driven outwardly against the housing, to thereby prevent the carrier blocks from locking, by being driven against the housing.

  • Patent number: 6216797
    Abstract: A thrust system for a horizontal directional drill is provided. The thrust system includes a drill boom having a drive sprocket positioned at the first end thereof and a driven sprocket positioned at the second end thereof. A carriage for supporting the horizontal drill is slidably received on the drill boom. The carriage includes idler sprockets positioned between the drive sprocket and driven sprocket in the drill boom. A serpentine chain extends about the drive sprocket, the driven sprocket and the idler sprockets in order to provide greater thrust and pullback of the drill at given torques. Rotation of the drive sprocket in a first direction draws the carriage towards the first end of the drill boom, and rotation of the drive sprocket in a second direction draws the carriage towards the second end of the drill boom.

  • Patent number: 6105684
    Abstract: The present invention relates to improvements in the operation and construction of roof bolters or roof bolt installation apparatus. The improvements comprise a roof bolter constructed so that the critical moving parts of its timber jack, feed frame, feed carrier and rotational unit are comprised of a rod and sleeve construction. Such construction allowing the protection of surfaces. The construction also includes feature of a spaced apart rod and sleeve construction which allows motive power units to be housed within the confines of the timber jack and feed carrier. The spaced apart arrangement also provides stability to the roof bolter.

  • Patent number: 6105683
    Abstract: The most dangerous task in mechanically driving a post into the ground is initially holding the post in an upright position while it is hammered to start it into the ground. When used with mobile equipment having an hydraulically driven post pounder the post picker not only eliminates the danger in starting a post into the ground, but additionally eliminates the necessity of using more than one man to do the job! A method is disclosed wherein a single hydraulic valve on a piece of mobile equipment may be used to control both the post picker and pounder.

  • Patent number: 5988298
    Abstract: A drilling device has a drilling mast and a movable drifter thereon with a drill rod stabilizing device for stabilizing drill rods in position during drilling. The stabilizer travels along the mast along with the drifter, and includes a locking arm that automatically opens and closes the stabilizer to allow passage of drill rods into an out of the drill line from storage, while supporting the drill rods during drilling. In a substantially vertical drilling position, the stabilizer is moved downwardly by gravity, and upwardly by the drifter's drive chain, which is retained in contact with the stabilizer by a pick-up link on the drive chain contacting stop blocks on the stabilizer. In a substantially horizontal drilling position, the stabilizer is moved in a return direction by the pick-up link and stop block combination.

  • Patent number: 5762148
    Abstract: A boring tool with two driving heads which are used to sink a casing string and a borer string includes a controllable coupling mechanism fitted between the two driving heads. A mechanism is also provided for the lower driving head, such that the driving head is subjected to an additional downwards acting force. When both driving heads are coupled, the upper driving head is also subjected to an additional, downwards acting vertical force. In order to free the top end of the casing string, the coupling mechanism can be released so that the upper driving head can be fully raised, whilst the lower driving head remains in position adjacent to the ground.

  • Patent number: 5746277
    Abstract: Augering device is disclosed which is useful for drilling holes in the ground at various angles under relatively low overhead or ceiling conditions. The device is suitable for mounting on a wide variety of vehicles ranging from the bed of small pickup trucks to very large track type caterpillars with booms. The device has an extendable mast powered by a downcrowding mechanism, a kelly assembly, and a kelly rotating mechanism. The extendable mast has a first mast member and a second mast member. A downcrowding hydraulic cylinder extends the second mast member away from the first mast member and pulls the second mast member towards the first mast member. The telescoping kelly sections include at least an outer kelly section and an inner kelly section. The outer kelly section has an axis parallel to but spaced apart from the axis of the first mast member. A bearing rotatable supports the outer kelly section and prevents axial displacement of the outer kelly section relative thereto.

  • Patent number: 5667021
    Abstract: A grade stake driver includes a frame for supporting a hammer and a grade stake under the hammer. A shuttle secured to the hammer movably mounts onto the frame to connect the hammer to the frame. A hoist secured to the shuttle mounts onto the frame to permit the raising and lowering of the hammer. A receiver mounted on the frame outputs a control signal in response to a transmitted signal. A switch mounted on the frame transforms the control signal into an on/off signal. A relay mounted on the frame connects the hammer to a power source in response to the on/off signal, thereby effecting the driving of the grade stake.
