    摘要: An apparatus for cutting excavations having a substantially planar face comprises a cutting tool which is rotatably mounted on a jib. The jib is mounted on a mobile machine for a pivotal movement in a plane which is transverse to the heading direction and is divided into two jib sections which are pivotally movable relative to each other about an axis which is substantially parallel to the pivotal axis of the jib. The cutting tool is rotatably mounted close to or at the free end of that jib section which is most remote from the pivotal axis of the jib.

    摘要: A device for guying a drift advancing machine within a drift has props which can be guyed between the drift roof and the drift floor and having articulated caps, connected to it. There are arranged at both sides of the longitudinal center plane of the machine at least one hydraulic cylinder-piston-aggregate between a supporting block fixed on the machine frame and the drift floor as well as between the supporting block and the drift roof in a guyable manner. The cylinder-piston-aggregates are articulatedly connected to floor supporting plates adapted to be pressed against the floor and to roof caps and are articulatedly connected to the supporting block, and the floor supporting plates and the roof caps are connected with the machine frame (1) via thrust supports.

    摘要: A mine drift advancing machine includes a cutting arm pivoted at its rear end to the machine chassis for movement about a horizontal axis and at its front end supporting a carrier which is pivoted to the arm for movement about a vertical axis. At least two horizontally spaced apart rocking levers are pivoted at their rear ends to the carrier for swinging about vertical axes and a lever drive is provided for swinging the levers simultaneously in the same directions. The forward end of each lever carrie at least one cutting tool which is rotatable about a generally vertical axis.

    摘要: Then invention relates to a cutting machine having cutting heads or drums which are supported to be freely rotating on a pivoting cutting arm, with a loading ramp or conveyor which extends in the direction to the work face to receive and transport the cut material, the loading ramp or conveyor being supported on the machine frame to be displaceable in the longitudinal direction of the cutting machine. The pivot axis of the cutting arm, which axis extends at right angles to the longitudinal direction of the machine, is provided to be adjustable relative to the machine frame in the longitudinal direction of the machine. The adjusting movement of the horizontal pivot axis of the cutting arm is coupled to that of the loading ramp or conveyor.

    摘要: A drift advancing or a partial-cut mining machine (1) comprises a cutting arm (11) being swivellable in a height direction around an axis (10). The front end of the cutting arm (11) is equipped with guides (26) transversely extending relative to the longitudinal axis (38) of the cutting arm (11) and having shiftably supported thereon a carrier (27) for the cutting heads (28, 29). The cutting heads (28, 29) are rotatably supported on the carrier (27) for rotation around vertical axes (46). The distance (a) between the axes of rotation (46) is, as measured in a transverse direction relative to the longitudinal axis (38) of the cutting arm, at most equal to half the width (b) of the drift face.

    摘要: A cutting machine (1) includes on its base frame (3) a carrier construction (19) for wall elements (21) and appliances (20) for drilling anchor bores and applying anchors the carrier construction being shiftable in longitudinal direction of the machine. The wall elements (21) are adjoining the drift roof (22) and, respectively, a cutting arm (11) via elastic sealing elements (23). The cutting arm (11) and the charging means (15) are pivotally linked to a shiftable frame (42). The cutting heads (28, 29) can be shifted along guides (31) in transverse relation to the longitudinal axis of the drift, the cutting heads (28, 29) being arranged between drift face (33) and wall elements (21).
