Definitions
- This invention relates to a rock cutting machine and has been devised particularly, though not solely for mining rock faces.
- the present invention therefore provides a rock cutting machine including: a boom rotatably mounted at a proximal end to a chassis adapted to be placed adjacent a rock face to be cut such that the boom extends from the chassis to a distal end adjacent the rock face, the boom having a longitudinal boom axis extending between the proximal and the distal ends, and a cutting device having a longitudinal axis and being pivotally mounted to the boom about a pivot axis at or adjacent the distal end of the boom and caused to pivot in use about the pivot axis by a drive mechanism, the pivot axis being offset from the longitudinal axis of the cutting device.
- the cutting device is an oscillating disc cutter and the longitudinal axis of the cutting device is collinear with the axis of oscillation of the disc.
- the pivot axis is offset from the longitudinal axis of the cutting device by a distance sufficient to cause the cutting disc on the oscillating disc cutter to withdraw slightly from the rock face in use during pivoting of the oscillating disc cutter about the pivot axis.
- the longitudinal axis of the cutting device is adjustable with respect to the pivot axis.
- the longitudinal axis of the cutting device is laterally adjustable from a position on a first side of the pivot axis to a position on an opposing side of the pivot axis.
- the boom is rotatably mounted to the chassis about mutually orthogonal rotation axes.
- the rotation axes are vertical and horizontal when the chassis is on a level surface.
- the boom is also rotatable about the longitudinal boom axis, allowing the orientation of the offset to be altered in use relative to the rock face.
- Fig 1 is a plan view of a rock cutting machine according to the invention
- Fig 2 is a plan view of an alternative embodiment of a rock cutting machine according to the invention
- Fig 3 is another plan view of the embodiment shown in Fig. 2.
- a cutting device 10 of the type generally described in international patent specification PCT/AU00/00030 is mounted on a boom 11 which in turn is rotatably mounted about a vertical rotation axis 12 to a chassis 13 adapted to be placed adjacent a rock face 14 to be cut.
- the boom 11 is typically mounted on a turntable 15 and rotated about the vertical rotation axis 12 by operation of piston and cylinder assemblies 16 and 17.
- the boom is also rotatable about a horizontal axis 27 to control the elevation of the cutting device 10, and is rotatable about the longitudinal axis 21 of the boom by piston and cylinder assemblies 28.
- the distal end 18 of the boom 11 is provided with a mounting yolk 19 incorporating bearings arranged to rotatably support a mounting pin or the like and forming a pivot axis 20 about which the cutting device 10 can pivot relative to the longitudinal axis 21 of the boom 11.
- the cutting device 10 has a cutting disc 22 engageable with the rock face 14 and has an axis 23 about which the cutting disc oscillates.
- the cutting device 10 is of the type generally described in PCT/AU00/00030, it will be appreciated that various types of similar cutting devices may be used, with or without the nutating feature described in that patent specification.
- the pivot axis 20 is offset from the axis 23 by a distance 24.
- the edge 25 of the disc cutter 22 that is actively engaging the rock face 14 is pivoting about the pivot axis 20 at a radius Rl.
- the forces acting on the leading edge 25 of the cutter 22, have components both parallel to axis 23 and perpendicular thereto, tending to cause the angle 26 between the axis 23 of the cutter shaft and the longitudinal axis 21 of the boom 11, to increase.
- hydraulic cylinders 29 These forces are typically reacted by one or more hydraulic cylinders 29.
- the hydraulic cylinders also provide for actuation of the cutter about the pivot axis 20.
- the offset also results in a change of the angle of the cutting edge of cutting disc 22 relative to the face 14 which has the effect of preserving the sharpness of the cutting edge.
- FIG. 2 A modification to the invention is shown in Figure 2 in which like numbers refer to like parts as shown in the preceding description of Figure 1.
- the cutting device is laterally movable, with respect to the arm axis 21 and yolk 19.
- the offset of the pivot axis 21 is achieved with a 19 is symmetrical mounting yolk in comparison to that shown in Figure 1.
- the lateral movement may be effected in a number of ways including eccentric cams, sliders or tracks mounted to either the cutting device, the yolk or an intermediate part.
- Figure 2 shows a hydraulically operated slider 30.
- the lateral movement allows the pivot axis 20 to be set on either side of the cutting disc axis, as can be seen by comparing Figures 2 and 3.
- the cutting device may be operated in bi-directional sweeps across the rock face without the need to rotate the entire cutting device around axis 21 as is required with the embodiment shown in Figure 1.
- this functionality reduces the time between sweeps thereby increasing efficiency.
