  • Patent number: 10648321
    Abstract: A drilling rig apparatus is disclosed for improving autodriller control during directional drilling. A BHA determines a relationship between downhole WOB and downhole differential pressure and sends the relationship to a surface controller. The relationships may be sent on a set periodic basis or dynamically in response to the relationships over time differing from each other above a threshold amount. The surface controller estimates downhole WOB by inputting surface differential pressure into a formula implementing the relationship from downhole. The estimated downhole WOB is input into the autodriller for control and is used to estimate MSE. Downhole WOB, either estimated or actual values, may further be used to determine a ratio between downhole WOB and surface-determined WOB values. If the ratio falls below zero in comparison to a prior ratio, then a slack-off rate is adjusted until the ratio reaches zero or a positive value again.

  • Patent number: 9010455
    Abstract: When the mode change knob of a multi-mode hammer drill is moved to the hammer only position, an electronic sensor sends a signal to a control logic circuit. When the user then depresses the trigger mechanically closing the ON/OFF switch, the control logic circuit applies a voltage either to a holding relay or to the gate of a triac which enables the relay or triac to conduct, thus providing a parallel circuit by-passing the ON/OFF switch. Consequently, when the user releases the trigger and opens the ON/OFF switch, the parallel relay or triac maintains current flow to the motor. It can be seen that in hammer only mode the user can activate the hammer drill by simply tapping the trigger to depress it and does not need to hold down trigger during use of the hammer in operation.

  • Patent number: 8372082
    Abstract: A force-limiting clutch for a surgical instrument includes a drive element and a transmission element. An actuator is coupled to the drive element, and a drive shaft is coupled to the transmission element for providing an output force. If the force input from the actuator to the clutch reaches a predetermined threshold, the force-limiting clutch “slips” and does not transfer the actuator force to the drive shaft to prevent excessive force/pressure output. Normally, drive features on the drive element engage with transmission features on the transmission element to transfer forces from the actuator to the drive shaft. When a threshold force is reached, the drive features slip past the transmission features. This clutch “breakpoint” determines the maximum loading that the surgical instrument can provide at its output. In various embodiments, multiple transmission features can be arranged in a serial manner, such that the force-limiting clutch provides multiple breakpoints.

  • Publication number: 20120097449
    Abstract: Method and apparatus for controlling rock drilling with a percussion device belonging to a rock drill to deliver stress waves to rock through a tool by pushing the tool against the rock by means of a feed motor and rotating simultaneously the tool by means of a rotation motor, whereby the maximum feed force is determined, pressure medium is supplied to the feed motor and to the rotation motor and the feed force is controlled according to the drilling conditions. The feed force is controlled on the basis of the feed speed and the rotation torque. The apparatus has a load control valve which controls the feed.

  • Patent number: 8151899
    Abstract: A method for producing Shockwave pulses in a tool direction (R) of a pulse machine (1) having a housing (2), wherein an impulse piston (4) is arranged, wherein the impulse piston is influenced by a first force in a direction opposite to said tool direction through a first fluid pressure (Pi) in a first chamber (7), and by a second force in said tool direction, wherein 'a Shockwave pulse is produced through a rapid relief of the first fluid pressure after displacement of the impulse piston (4) relative to the housing in a direction opposite to the tool direction, is distinguished in that the length of the shock wave is controlled by the length (L) of said displacement is regulated. The invention also concerns a device, rock drilling machine and a rock drilling rig.

  • Patent number: 8122974
    Abstract: Apparatus for controlling a drilling machine to drill a series of parallel holes, where the drilling machine comprises a carrier vehicle movable over the terrain, a boom mounted on the vehicle for movement side to side on the vehicle, a mast carried on an outer end of the boom and movable about two separate axes relative to the end of the boom, includes a first sensor responsive to an azimuth angle relative to the earth's magnetic north direction and two additional sensors, which are used to measure the two inclinations relative to two vertical planes transverse to and longitudinal of the boom. The sensor system is mounted in an housing on the mast close to the longitudinal center of the mast and offset to the side. A controller calculates from the sensed values of the azimuth and inclination angles required target angles for the mast for drilling each hole.

  • Patent number: 8092125
    Abstract: A pneumatic feed drill has a control unit that repeatedly advances and retracts the drill bit in peck cycles while drilling the hole. The drill has a hydraulic damper cylinder with a damper rod protruding from it that limits the speed of advancement of the drill bit. A retainer device is mounted to the damper rod and prevents the damper rod from resetting to its initial position during the peck cycles. The retainer device releases the damper rod to reset when the drill bit has reached total depth. A safety device is pivotally mounted to the housing and has a closure tab that blocks access to the start button of the drill unless the damper rod is in its initial position.

  • Patent number: 7896099
    Abstract: The object of the invention is to provide a drilling device which is compact and has good sliding properties. The object is achieved by an upper beam for use with a lower beam in a telescopic feeder for a drilling device for rock drilling. The upper beam extends along a longitudinal axis and has a generally U-shaped cross section comprising a bottom wall and a first and a second side wall. Each side wall has an inward surface and an outward surface. The upper beam comprises a cooperating member intended for sliding cooperation with the lower beam. The cooperating member comprises an attachment structure extending outwardly from each outward surface of each side wall. Each attachment structure is intended for fixed mounting of a crank block bracket, which crank block bracket faces the outward surface of each side wall.

  • Patent number: 7896098
    Abstract: Power tools are taught that may include, for example, means for detecting impact sounds generated, e.g. by a hammer strikes an anvil or by oil pulse from an oil unit. The detecting means may include a receiver (30) adapted to selectively convert sound within a narrow frequency range into electric signals. Preferably, the impact sounds fall within the narrow frequency range of the receiver (30). A processor 38 may be utilized to control the motor (22) in order to stop the rotation of the hammer when a pre-determined number of impact sounds has been detected by the detecting means. In addition or in the alternative, various means for setting various operating conditions are taught, including dials 34, sound sensors 30, keypads and remote control devices 250. Further, means for performing maintenance condition status checks are taught.

  • Patent number: RE44311
    Abstract: A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The controller may opt to reduce the torque applied to shaft to a non-zero value that enables the operator to regain control of the tool.
