    Abstract: A control system for an air driven drill is described, wherein the control system is of the kind that provides a feed stroke to a drill bit. The system comprises an interrupt line so that compressed air fed to a feed chamber is also fed to a clamp chamber whereby the unbalanced force on the feed piston becomes balanced so as to stop the feed stroke. An adjustable frequency generator is provided to impose a pulsating pressure variation in an air pressure supply. During a feed stroke under which compressed air is fed to the feed chamber, air fed to the clamp chamber via the interrupt line is caused by the adjustable frequency generator to have a pulsating pressure, so that the feed stroke is caused to be stopped for a first period, then resumed for a second period, to provide a periodically interrupted feed stroke.

The oscillation of the drill and housing causes the lever (18) to pivot about the fixed fulcrum (8) against the bias of the biasing means (10). This disengages the grip of the engaging formation (20) and the drill is advanced along the rail (4).

  • Patent number: 7410008
    Abstract: A ground rod driver that uses an industry standard connecting plate to physically attach the driver to Skid Steer type equipment. The driver has a hydraulic, impact driving hammer connected to an alignment beam that enables vertical movement of the hammer. Operation of the driving hammer, as well as up and down motion of the driving hammer is derived from the accessory hydraulic system and connections of the Skid Steer. Simple operating control valves, flow control valve and hydraulic hoses, and an operating station are mounted directly to the driver.

  • Patent number: 7040413
    Abstract: The striking mechanism has a hammer barrel (3), which has at least one control opening (23) through which, in an idle position, the air can escape from the hammer barrel (3), and which in a striking position is closed by a covering (25) that prevents the escape of air. To achieve the greatest possible sealing off of the at least one control opening (23) and thus high efficiency of the striking mechanism, the covering (25) is molded from an elastomer.

  • Publication number: 20030047332
    Abstract: A carriage system supports an impact or driver tool. The carriage system has a support member that extends upwardly from a base platform. Support arms are rotatably connected to the support member at medial portion of the arms at different elevations above the support member. A proximal end of each of the arms rotatably connects to a weight, while a distal end of each of the arms is adapted to rotatably connect to the driver tool. The weight is located on an opposite side of the support member from the driver tool when the driver tool is attached. When the weight is moved in a vertical direction, the arms rotate in combination with the movement of the weight. The arms rotate about their respective medial connections, thereby forcing the ends that rotatably connect to the driver tool to move in a vertically opposite direction than the weight.

  • 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: 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.
