    摘要： Some embodiments of the invention concern HDD in an automatic drilling mode. Such embodiments can include maintaining a constant output parameter while performing a drilling operation using an HDD rig (20) having a thrust pump, generating hydraulic fluid pressure measurements from one or more pumps of the HDD rig, comparing the hydraulic fluid pressure measurements to a variable pressure limit, calculating a derivative value using the measured hydraulic fluid pressure measurements, comparing the derivative value to a derivative threshold, decreasing the variable pressure limit when the derivative value exceeds the derivative threshold, wherein the amount that the variable pressure limit is decreased is based on one or more of the hydraulic fluid pressure measurements, and reducing output of the thrust pump when the comparison of the hydraulic fluid pressure measurements to the variable pressure limit indicates that one or more of the hydraulic fluid pressure measurements exceed the variable pressure limit.

    摘要： A method and a device for controlling the feeding on a feed beam (3) of a to and fro movable rock drilling machine (2), which includes a percussive device and a rotation motor providing a rotation moment, wherein a parameter related to the rotation moment is monitored and the feeding is controlled by flow control as a response to variation of the value of the parameter, wherein a feed flow to a fluid motor means providing the feed is reduced as a function of a change of the parameter value corresponding to an increase of the rotation moment over a first level. For parameter values corresponding to the rotation moment being below the first level, feeding is controlled by pressure control as a response to the variation of the value of the parameter, wherein a feed pressure for said fluid motor means is reduced as a function of a change of the parameter value corresponding to an increase of the rotation moment. The invention also concerns a rock drilling machine and a drilling rig.

    摘要： A hydraulic control system includes a first motor, a second motor, a pump operatively associated with the first motor, a first coupling valve operatively associated with the second motor, first parallel valves operatively associated with the second motor, and a first switching valve operatively associated with the first coupling valve and the first parallel valves. The first switching valve is configured to switch the first coupling valve between a first coupling state and a second coupling state opposite the first coupling state and to switch the first parallel valves between a first parallel state and a second parallel state opposite the first parallel state. While the first parallel valves are in the first parallel state a portion of the output of the first motor drives the second motor while the first parallel valves are in the second parallel state, the output of the pump drives the second motor.

    摘要： Die erfindungsgemässe Bohrvorrichtung 1 weist eine Spülvorrichtung zum Spülen einer Bohrung 5 mit einem Spülfluid 7 auf. Eine hydraulisch angetriebene Vortriebseinrichtung 21 ist vorgesehen einen Bohrer 2 in der Bohrung 5 vorzutreiben. Ein Durchflussbegrenzer 30 ist in Hydraulikleitungen 25 der Vortriebseinrichtung 21 angeordnet, um die Vortriebsgeschwindigkeit einzustellen. Der Durchflussbegrenzer 30 weist ein durch Druck betätigbaren Stellelement 38 zum Einstellen einer Durchflussbegrenzung auf. Eine pneumatische, hydraulische und/oder mechanische Kopplung 39 überträgt den Druck des Fluids 7 auf das Stellelement 38.
