Definitions

  • the invention relates to a tunnel boring machine or Pipe jacking machine for hard rock drilling with a die Rotating full cut drill head carrying drilling tools.
  • EP 520 909 A1 includes a tunnel boring machine a drill head in the form of a disc and a hollow shaft
  • the extension has become known, which is connected to two drives stands, whereby the drill head is rotated.
  • the drill head is in a ring joint over the shaft part, consisting of rings opposite an outer ring, which the Shield forms, stored.
  • the multi-ring joint consists of one or more rings that are not concentric with each other stand, whereby when the or the Inner rings opposite the inner ring of the shield and the drill head shaft the axis of rotation of the drill head in any eccentric position to the longitudinal axis of the tunnel can. This measure is particularly advantageous if wear of the drill bits is to be compensated for or a Overlap is needed around the tunnel boring machine and the Insert the drill head into the curvature.
  • the invention now aims to set up a device mentioned type to the extent that without mechanical additional facilities the entire face can be dismantled and withdrawn if necessary can be done from the tunnel tube without digging.
  • the drill according to the invention or Tunneling machine of the type mentioned at the outset essentially in that the drill head and the enveloping circle of the tools unite Have diameter that is smaller than the diameter the bore and that the geometric axis of the enveloping circle Tools of the full cut drilling head relative to the axis of rotation eccentrically arranged or displaceable.
  • the geometrical The axis of the full cut drill head is defined here through the enveloping circle of the tools on the full cut drilling head, and a rotation of such a drill head about an axis of rotation, which is different from the geometric axis, leads to the fact that a larger cross section can be reduced, than this corresponds to the cross section of the full cut drill head alone would.
  • a configuration allows by simply relocating the full cut drill head To take position in which one Pull out the drill head and the entire tunnel boring machine also with existing extensions or pipework or Convergence is easily possible.
  • the tunnel boring machine according to the invention or Pipe jacking machine developed so that the drill head a Has carrier disc on which hard rock tools such e.g. Disks are arranged, their radial distance from each other taking into account the eccentricity of the enveloping circle the disks to the longitudinal axis of the tunnel or to the axis of rotation are selected in this way is that the cutting line distances to the longitudinal axis of the tunnel larger radius are smaller than on a smaller one Radius.
  • Discs or roller chisels are ideal for this as hard rock tools, with a corresponding Arrangement on the drill head with smaller ones on a larger radius Cutting line spacing a safe machining with simultaneous Reduction of the radial force components and the results in off-center loading of the drill head.
  • the order the drilling tools lead to an eccentric envelope which is smaller than the raw diameter of the tunnel tube, when using a carrier plate for drilling tools this can be arranged as usual centrally to the drill head, so that Jamming of larger, detached rocks can be avoided.
  • the arrangement of the individual disks in in a way that an enveloping circle of the entire drilling tool is eccentric to the pipe axis allows the dismantling of the desired clearance over the actual diameter of the Drilling tool or drill head.
  • the training is advantageous to reduce wear hit that the tools are relative to the axis of the drill head arranged asymmetrically, especially along a spiral are, the disks in a particularly advantageous manner larger diameter flatter to the working face than on a smaller diameter. Both of these measures minimize wear and thus reduce the required Maintenance effort and are particularly related with the eccentricity provided according to the invention Cutting movement particularly advantageous.
  • the training can be taken with advantage so that the Tunnel boring machine via sliding or movable supports is supported in the tunnel tube.
  • a movable one Support can take place via a self-propulsion and for example in the form of crawler tracks.
  • Such movable supports are separate from the to provide actual spreading in the tunnel tube with which is basically a step under the respective solution one of the two spreading and advancing or pulling the other spread is possible.
  • the tunnel boring machine according to the invention or Pipe jacking machine developed so that the drill head by rotating the carrier disk relative to the axis of rotation the drive can be pivoted into a position in which the outer contour of the carrier disc and the drilling tools inside the projection of the clear diameter of the removed or piped tunnel on the face. in principle describe the individual disks according to their orientation a circular movement relative to the desired tunnel axis over the face.
  • the drill head in one bring certain, predetermined rotational position and then the pivoting of the axis by means of a support relative to the longitudinal axis of the tunnel to withdraw to ensure.
  • the Training taken so that the axis of rotation of the drive of the drilling tools through the front or rear support the tunnel boring machine in the tunnel tube relative to the longitudinal axis of the tunnel is shiftable, the tunnel boring machine in a simple manner Movable on caterpillars or rails or wheels is trained and equipped with a travel drive can be.
  • a particularly favorable introduction of force with at the same time low Wear can be ensured that the Caliber tools on the carrier plate within a center angle of less than or equal to 90 ° are arranged.
  • the front and the rear vertical Outriggers are usually mandatory components a double braced hard rock machine, the Stepping occurs by actuating the double tension.
  • the elimination of an adjustment mechanism of the drilling tool is reduced the susceptibility to failure in harsh operating conditions in the hard rock driving.
  • Envelope circle can the drilling tool through the above construction measures by different arrangement of the disks can be optimized without this deteriorating the Possibilities, the tunnel boring machine or pipe jacking machine going back would bring with it.
  • the carrier plate or the drilling tool also deviates from the circular shape Have outline shape, so that by simply pivoting one Position can be taken in which the withdrawal is made possible.
  • FIG. 1 shows a side view of a tunnel boring machine in the extended position
  • Figure 2 is an enlarged Detailed view of the full cut head in working position
  • 3 is a front view of a full cut drilling head in the working position
  • 4 shows a drill head according to FIG. 3 in a raised position Position for retraction
  • Fig.5 another embodiment a drill head with a different arrangement of the caliber tools 6 in the working position and a transport position for the embodiment according to FIG. 5, the one shown in FIG Section line II / II essentially with the illustration according to Fig. 2.
  • Fig.1 there are disks 1 to 18, of which the simplicity only discs 8 and 18 are shown, with one Drill head 19 can be seen connected.
  • the drill head 19 is from a geared motor 20 rotatable about an axis of rotation 21 driven, the axis of rotation 21 for propulsion in a position is pivoted which is the longitudinal axis 22 of the tunnel equivalent.
  • the lifting via a hydraulic cylinder-piston unit 23 of a movable support shoe 24 can retract while maintaining a free space 25 of the tool from the working position.
  • the side supports 26 and 27 are retracted, which together with hydraulic cylinder piston units 28 form a walking mechanism.
  • a rear support 29 is provided, which also sliding or with its own drive and a crawler track can be designed to be movable.
  • a conveyor 30 which to subsequent conveying means 32 in the tunnel tube 31 yields.
  • FIG. 2 In the illustration according to FIG. 2 is again a caliber tool 18 and a central disc 1 on the drill head 19 can be seen.
  • the axis of rotation 21 coincides with the longitudinal axis 22 of the tunnel together and the hard rock drilling head is in his Working position.
  • the cut material over baffles 33 is transferred to the conveyor 30 and removed can be.
  • the drill head is located with disks 1 to 18 in the working position, and the axis of rotation 21 coincides with the longitudinal axis 22 of the tunnel.
  • the axis of rotation 21 coincides with the longitudinal axis 22 of the tunnel.
  • the cutting line distances are here, as from the 3 to 6 can be seen, chosen so that in the outer area due to a much flatter position of the drilling tools a significantly smaller cutting line distance was maintained will than in the central area of the bore.
  • the cutting rollers are asymmetrical arranged to optimize for radial forces to surrender.
