    摘要: A mining machine (10) including a frame (14), a cutting head (26) movably coupled to the frame (14) and pivotable about an axis (52) that is substantially perpendicular to the first mine surface, and a first actuator (542) for stabilizing the frame (14) relative to the first mine surface. The first actuator (542) is coupled to the frame (14) and includes a first end (598) extendable in a first direction to engage the first mine surface. The extension of the first actuator (542) is automatically controlled based on measurements of at least one indicator of the force between the first actuator (542) and the first mine surface.

    摘要: An oscillating disc cutter (10) including a cutting disc (602) and a drive mechanism. The drive mechanism including a drive shaft (612) to effect eccentric oscillation of the cutting disc and a radial bearing (609) disposed to permit relative rotation between the drive shaft and the cutting disc. The cutter further including a hydrostatic axial bearing (700) disposed to react axial forces while accommodating induced rotation of the cutting disc when operatively engaged and to induce a rotational drag thereby limiting rotational peed of the cutting disc when free running. A water pressurised fluid bearing (605) induces a predetermined axial load in the hydrostatic bearing such that a predetermined maximum running clearance in the hydrostatic bearing is maintained.

    摘要: A rotary trench cutting or rock milling saw unit (12) is supported on a head (18) for movement about two mutually perpendicular axes (50,62). The head is adapted for pivotal mounting on a backhoe boom (20) or similar positioning structure. Rotary rock cutting wheels are driven by a hydraulic motor and a support vehicle (24) for the saw unit includes a hydrostatic drive system with a variable displacement hydraulic pump driving variable displacement track drive motors which may be set in a slow speed operating mode for trench cutting operations or a high speed mode for tramming between work sites. A constant rate of power input to the saw unit is maintained by sensing saw drive motor supply pressure and adjusting tract drive motor supply pump displace­ment to maintain a constant feed or rock cutting rate. The apparatus includes hydraulically operated actuators for rotating the saw unit and its support boom about a vertical axis (40) with respect to the apparatus undercarriage, elevating the boom with respect to the undercarriage, and moving the saw unit about three mutually perpen­dicular axes (40,50,62) with respect to the support boom. Each of the actuators includes a control valve which may be selectively positioned to operate the actuators in reverse directions, lock the actuators in a predetermined position, or permit the actuators to oscillate or rotate the saw unit with respect to the various positioning axes of rotation when the saw unit is confined in a trench.

The head is adapted for pivotal mounting on a backhoe boom or similar positioning structure. Rotary rock cutting wheels are driven by a hydraulic motor and a support vehicle for the saw unit includes a hydrostatic drive system With a variable displacement hydraulic pump driving variable displacement track drive motors which may be set in a slow speed operating mode for trench cutting opations or a high speed mode for tramming between work sites. A constant rate of power input to the saw unit is maintained by sensing saw drive motor supply pressure and adjusting tract drive motor supply pump displacementto maintain a constantfeed or rock cutting rate. The apparatus includes hydraulically operated actuators for rotating the saw unit and its support boom about a vertical axis with respect to the apparatus undercarriage, elevating the boom with respect to the undercarriage, and moving the saw unit about three mutually perpendicular axes with respect to the support boom.

    摘要: A cutting assembly for a rock excavation machine including a frame. The cutting assembly includes a boom supported on the frame and a cutting device. In some aspects, the boom includes a first portion and a second portion, and the first portion includes a first structure and a second structure slidable relative to the first structure. The second portion includes a first member pivotably coupled to the second structure, and a second member pivotably coupled to the first member. The cutting device is supported on the second member. In some aspects, a material handling device is supported independently of the boom and movable between a retracted position and an extended position independent of the boom.
