Definitions
- the invention relates to a tunneling or extraction machine for the extraction of rock with disc or roller tools working according to the undercut principle, which are rotatably mounted on a pivotable cantilever arm of the machine, with a head carrying the tools, the axis of rotation of which essentially in the direction the axis of the cantilever arm.
- Undercut cutting roller or milling drilling tools in which removal is carried out in layers from the center of a tunnel, tunnel or shaft without a pre-drilled hole from the inside to the outside, are also described in DE 41 42 800 AI. With this device, radial undercuts are removed from inside to outside, layer by layer, the tools being attached to a rotatingly driven drill head.
- Low-profile devices which are equipped with milling heads and generally have their own drive, have already been known for driving low seams. With such known devices, which also known as "narrow reef miners", but the material was usually cut.
- the tunneling or extraction machine essentially consists in the fact that the axis of rotation of the head bearing the tools on the cantilever arm is pivotally mounted on the machine frame about an axis crossing the axis of the cantilever arm and extends in the direction of advance in front of the pivot axis of the cantilever arm.
- the axis of rotation of the head carrying the tools which is fixed on the extension arm, is pivotally mounted on the machine frame about an axis crossing the axis of the extension arm, creates a configuration in which the working face can be broken down essentially along an arc, with the individual disc or roller tools can be used in the optimal position. Because the axis of rotation of the head carrying the tools runs in the direction of advance in front of the swivel axis of the cantilever arm, the disc or roller tools can be set up in such a way that a corresponding clearance angle is guaranteed over the entire front of the excavation and each is particularly economical when the cantilever arm is pivoted Crushing work can be done.
- the first cutting tool of a plurality of cutting tools arranged in one plane is used while maintaining the desired free cutting angle, the subsequent tools each entering the track of this tool.
- an optimal free cutting angle can be achieved since the tools used one behind the other are not used in the tangential plane of the swiveling movement and therefore also for subsequent following tools a corresponding clearance angle is always guaranteed.
- the design here is advantageously made such that the pivot axis of the cantilever arm is arranged normal to the direction of advance, such a design offering the possibility of making the machine extremely low and compact overall.
- the design is advantageously made such that the diameter of the enveloping circle of the cutting tools is greater than or equal to the machine height, the pivoting angle of the axis of the cantilever arm preferably starting from a direction of the axis of the cantilever arm that is transverse to the direction of advance less than 150 °, preferably about 120 °.
- the design is advantageously made such that the pivot bearing of the cantilever arm is arranged on a slide which is displaceable in the longitudinal direction of the machine frame.
- a machine positioned in the route can thus first be appropriately braced or fixed in the route, whereupon a burglary cut can be achieved by moving the sliding carriage in the direction of the working face, from which the further one starts at a clearance angle of, for example, approximately 5 ° Cutting work can be done while optimizing the broken portion.
- the design is such that the cutting edges of the disks are arranged on the head in a plane normal to the axis of rotation of the head, which is at an angle between 2 ° and 10 ° with the tangent to the enveloping circle of the swiveling movement of the arm. preferably about 5 °.
- Such training allows a particularly quick and economical breaking of hard rock, in the frame such a configuration at least 3, preferably at least 4, disks are arranged on the end face of the head.
- the design is advantageously made such that the cantilever arm is fixed to the swivel bearing in a manner that can be displaced relative to the swivel axis of the swivel bearing normally to the swivel axis.
- the relative displacement of the axis of the cantilever arm relative to the pivot axis of the pivot bearing crossing this axis leads to an adjustment of the clearing angle, which can be adjusted in this way, via the defined pivot angle.
- the design is advantageously made such that the machine frame can be braced with spreaders or punches in the tunnel or excavation tunnel or seam.
- a particularly simple maneuverability of the entire device can be achieved in that on the rear end of the slide facing away from the swivel bearing there is arranged a plunger which is displaceable transversely to the longitudinal direction of the machine and can be extended essentially parallel to the swivel axis for support to the sole or for tensioning in the seam.
- the design is advantageously made such that a loading chute is arranged at the end of the machine adjacent to the swivel mechanism, a safe and complete clearing of such a loading chute being achieved in a particularly simple manner in that with the swiveling boom with the Loading chute interacting clearing blades are connected.
- the clearing blades interacting with the loading chute can be designed to be pivotable or extendable, so that they only interact with the loading chute in one of the two pivoting directions of the extension arm.
- the machine can be arranged asymmetrically in the path, so that on the side on which the burglary cutting process begins, a corresponding space is created for the tracking of discharge devices. Since the cutting drum is used with a clearance angle of about 5 ° to the lateral face when cutting, and a break-in is carried out via the feed device, whereupon the cantilever arm is subsequently pivoted by approximately 120 °, the disks lying one behind the other are used Always in the same track, which means that a further material cut is made so that material with a high proportion of crushing is broken out.
- the material can be removed over the entire cross-section to be dismantled, so that the corresponding space is created for the displacement of the machine frame, a distance predetermined by the length of the permissible displacement path of the slide being able to be reduced without displacement of the machine frame, for which only the Slide is to be moved accordingly.
- the swivel mechanism with which the cantilever arm can be pivoted about an axis lying transversely to the direction of advance, can be driven in a simple manner by means of hydraulic cylinders which are supported on the machine frame, so that it can also be found here with low-profile devices.
- FIG. 1 shows a plan view of the machine according to the invention
- FIG. 2 shows a view of the machine in the direction of arrow II in FIG. 1
- FIG. 3 shows a view of the machine according to FIG 1 in the direction of arrow III in FIG. 1
- FIG. 4 is a view of the machine according to FIG. 1 in the direction of arrow IV in FIG. 1.
- a machine frame 1 is shown, on which a carriage 2 is mounted for longitudinal displacement in the direction of the double arrow 3.
- An abutment bracket is arranged on the carriage 2 at the rear end, on which pivot cylinders 4 and 5 are supported for pivoting a pivoting mechanism 6 about a pivot axis 7 crossing the direction of advance 10.
- a cantilever arm 8 is fixed, the axis 20 of which, like the drill head axis 9 of the cutting head 13, lies in the direction of advance 10 in front of the swivel axis 7 of the swivel mechanism 6.
- the boom can also be cranked or kinked.
- the alignment of the drill head axis ensures that when the swivel mechanism 6 is pivoted in the direction of the double arrow 11 over the entire swivel angle of approximately 120 °, a corresponding free cutting angle ⁇ of the cutting disks 12 of a cutting head 13 is ensured.
- a loading chute 15 can be seen, via which material can be pushed in the direction of arrow 16 onto a discharge device, not shown.
- Lateral support claws 17 are arranged on the machine frame or on the slide, with which the machine can be clamped between the roof and the sole.
- a further support ram 18 is arranged, which can be moved laterally in a corresponding guide via a hydraulic cylinder olbenaggregat 19, so that when the ram 18 is extended, the slide and thus the machine frame 1 can be moved laterally, provided the support rams 17 are retracted are.
