Definitions
- the invention relates to a cutting machine with cutting heads or rollers rotatably mounted on a pivotable cutting arm with a loading ramp or a conveyor running in the direction of the working face for receiving and discharging the cut material, in which the cutting arm abuts on a conveyor is mounted on sliding in the machine longitudinal ver ⁇ running guides sliding carriage.
- Cutting machines or tunneling machines in which the Ab ⁇ building tools are movable relative to the machine frame on a carriage for example, the AT 393295 B ent take.
- this known tunneling machine guide rods are provided on the frame of the tunneling machine within the crawler tracks, on which a slide ver ⁇ go.
- the carriage has for this purpose tubular guides, wherein the corresponding mobility along the guide rods is ensured by the fact that the axial length of the pipe guides is shorter than the axial length of the guide rods.
- discharge conveyor are movable in a backdrop articulated with this carriage.
- AT 404863 B and AT 404282 B disclose a slide which is designed as a self-supporting box profile and on to rods formed longitudinal guides is slidably mounted on the frame.
- the rod-shaped longitudinal guides are again connected to the frame of the crawler track,.
- the conveyor must be guided through the clear cross-section of the carriage designed as a self-supporting box profile.
- the invention now aims to provide a tunneling machine with a low pitch frame slide construction which is suitable for particularly low seams and has improved dome trough handling.
- the Aus ⁇ formation of the tunneling machine according to the invention of the type mentioned above consists essentially in that the carriage carries in the machine longitudinal direction extending guide rods, which engage in tubular guides of a chassis bearing Ma chine frame.
- the tubular guides have curved generatrices to form a convex inner contour.
- the tubular guides are suitable in a particularly simple manner for the formation of particularly stable low-building machine frames, wherein this machine frame as a whole can be constructed relatively short, without losing the required rigidity and strength.
- this machine frame as a whole can be constructed relatively short, without losing the required rigidity and strength.
- the Aus ⁇ education according to the invention therefore made such that the carriage is designed as an upwardly open channel, in the side walls of the pivot axis for the vertical pivoting of the Schrämarms is stored.
- Such an upwardly open channel can be adjusted over a relatively long axial displacement, without causing collisions of the conveyor with frame members of the machine frame.
- the training is so ge ge that the tubular guides between crawlers are arranged and are connected to transverse to the tube axis struts or plates to form a frame, whereby a high stability of the machine frame is ensured with small dimensions ,
- the tubular guides can in this case be welded in accordance with both the crawler track and the connecting plates, resulting in a particularly compact and torsionally rigid construction.
- the short design allows at the same time to divide the Maschinen ⁇ frame itself in the axial direction and also to improve the flexibility, which in turn serves to improve the depression and Kuppenloomkeit.
- the design is advantageously such that a frame part, which is pivotable about at least one pivot axis extending transversely to the machine longitudinal direction, is pivotally connected to the frame comprising the tubes.
- Such an articulated pivotable frame part arranged in the rear part of the machine can be raised in the vertical direction to achieve the desired transfer height of the conveyor, wherein improved cornering can be achieved by further pivoting of a frame part in the rear area of the machine.
- the training is such that at the the Schrämarm ask- arranged rear end of the carriage a transversely to Maschi ⁇ nenlijnsachse extending pivot axis for the conveyor or a conveyor trough is arranged, whereby relatively heavy components, such as the power supply for the drives of the machine can be pivoted laterally in curves.
- the design is advantageously such that the conveyor trough over the entire length of Conveyor is designed as an open-topped channel.
- the pivotability of the rear machine part or of the hinged rear frame part hingedly connected to the machine frame can be further improved by connecting this rear frame part gimbal to the frame part having the tubular guide.
- FIG. 1 shows a perspectiveylon ⁇ view of the machine according to the invention in a diagrammatic Dar ⁇ position
- Figure 2 shows the displaceable in the machine longitudinal direction frame in an enlarged view
- Figure 3 the Maschinen ⁇ frame with hinged on the machine frame connected rear pivotal frame part
- Fig. 4 is a section along the line IV / IV of Figure 3, wherein the carriage has been inserted into the machine frame.
- a tunneling machine 1 is shown, the crawler chassis 2 is connected to a machine frame 3.
- a carriage 4 is displaceable in Maschinen ⁇ longitudinal direction, wherein on the carriage 4 about a schematically indicated with 5 horizontal pivot axis a Aus ⁇ leger or Schrämarm 6 is pivotally mounted with a rotatably mounted cutting roller 7 in the vertical direction.
- a further frame part 9 is pivotable about a pivot axis 8 in the vertical direction, by means of which a conveyor located in the gutter can be pivoted in the vertical direction to set the desired discharge height.
- a further pivotable rear frame member 10 is arranged, which can be pivoted laterally in curves aus ⁇ , as will be explained in more detail in subsequent figures.
- FIG. 2 the carriage 4 is shown enlarged, wherein the boom 6 has been removed. Clearly visible is connected to the carriage 4 end support 11, which carries guide rods 12. These guide rods 12 are inserted into corresponding tubular guides of the machine frame, these tubular guides being designated by 13 in FIG.
- the machine frame with the crawler chassis 2 is now apparent, which consists of a first tubular guides 13 supporting the frame 3 and a pivotable about a substantially vertical axis 14 frame part 10.
- pivoting cylinders 15 for the vertical pivoting of the extension arm 6, as can be seen in FIG. 1 are also shown, as are further pivoting cylinders 16 for a corresponding adjustment of the second frame part 10 with respect to FIG connected to the crawler chassis first frame part 3.
- the schematically indicated with 14 axis is not formed as a pure vertical pivot axis but as a spherical bearing, which allows a gimbal Verschenk- availability also transversely to the axis 14.
- the inner contour of the tubular guides is not formed by straight generatrix, but rather by curved generatrix, so that the rods 12 are guided with corresponding play in the guides 13, which allow a tilting movement about an axis substantially parallel to the ground plane. 4, the frame construction can now be seen in section, the rods 12 of the slide 4 now being pushed in the tubular guides 13.
- the tubular guides are respectively welded to the crawler track 2 and connected to each other via plates 17 to a particularly rigid box-shaped frame member.
