초록 ▼

A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.

대표청구항 ▼

1. A mining machine comprising: a frame;a cutting head moveably coupled to the frame;a first actuator for stabilizing the frame relative to a mine surface, the first actuator being coupled to the frame and including a first end extendable in a first direction to engage the mine surface; anda control system in communication with the first actuator and configured to operate the first actuator, the control system detecting a time required for the first end to extend to a position such that at least one indicator of a force between the first actuator and the mine surface reaches a predetermined value, the control system controlling the extension of the first end based on the detected time. 2. The mining machine of claim 1, further comprising a second actuator for stabilizing the frame relative to the mine surface, the second actuator being coupled to the frame and including a first end extendable in a second direction to engage the mine surface, wherein the control system is in communication with the second actuator and is configured to operate the second actuator, the control system detecting a time required for the first end of the second actuator to extend to a position at which at least one indicator of the force between the second actuator and the mine surface reaches a predetermined value, the control system controlling the extension of the first end of the second actuator based on the detected time. 3. The mining machine of claim 1, further comprising a second actuator for stabilizing the frame relative to a second mine surface, the second actuator being coupled to the frame and including a first end extendable in a second direction to engage the second mine surface, wherein the control system is in communication with the second actuator and is configured to operate the second actuator, the control system detecting a time required for the first end of the second actuator to extend to a position at which at least one indicator of the force between the second actuator and the second mine surface reaches a predetermined value, the control system controlling the extension of the first end of the second actuator based on the detected time. 4. The mining machine of claim 1, further comprising a headboard pivotably coupled to the first end of the first actuator and configured to engage the mine surface. 5. The mining machine of claim 4, wherein the headboard is pivotably coupled to the first end of the first actuator by a ball-in-socket joint. 6. The mining machine of claim 4, wherein the headboard has a substantially triangular profile. 7. The mining machine of claim 1, further comprising at least one spacer positioned between the first end of the first actuator and the first mine surface. 8. The mining machine of claim 1, wherein the first actuator is a hydraulic cylinder, and the at least one indicator of force between the first actuator and the mine surface is a hydraulic pressure within the hydraulic cylinder. 9. The mining machine of claim 1, wherein the first actuator is a hydraulic cylinder, and further comprising a directional control valve for controlling fluid flow into and out of the first actuator in order to extend and retract the first actuator. 10. The mining machine of claim 1, wherein the cutting head is pivotable about an axis that is substantially perpendicular to the mine surface and includes at least one oscillating cutting disc. 11. The mining machine of claim 1, further comprising a sensor in communication with the control system, the sensor detecting the at least one indicator of the force between the first actuator and the mine surface. 12. The mining machine of claim 1, wherein the sensor is a pressure transducer detecting a pressure in the first actuator. 13. The mining machine of claim 1, further comprising a displacement sensor in communication with the control system, the displacement sensor detecting a position of the first actuator. 14. The mining machine of claim 1, wherein the control system includes a timer detecting the time required for the first end to extend to a position such that at least one indicator of a force between the first actuator and the mine surface reaches a predetermined value.
