Definitions

  • the present invention relates to a tunneling machine with a chassis and a cutting boom or frame, wherein the cutting boom or frame at least two rotating cutting heads whose axes of rotation extend in the advancing direction or include an acute angle with the advancing direction and which together define a cutting profile with a profile width , And two substantially parallel and behind the cutting heads arranged cutting rollers, which are positioned on the sole or the ridges.
  • Jacking machines with cutting rotors are commonly referred to as "Marietta drills", the cutting unit having two or more rotating cutting heads.
  • the two cutting heads define a cutting profile with a maximum profile width, wherein the cutting tools are usually arranged on the cutting heads such that cutting tools of one cutting head engage in rotation between cutting tools of the other cutting head, so that the circular surfaces of the respective cutting profiles overlap each other.
  • the common cutting profile of the two or more juxtaposed and preferably arranged at the same height cutting heads therefore usually corresponds to a corresponding number of mutually partially overlapping circular areas, with so-called profile gussets remain between the individual circular areas in the region of the sole and the ridges.
  • the edge of the profile is bounded by two semicircles.
  • US Pat. No. 3,343,882 discloses a Cutting chain known, with the sole profile and the ridge profile can be partially straightened.
  • the present invention therefore aims to provide a tunneling machine with which it is possible to drive or form a substantially rectangular tunnel profile and to avoid the disadvantages described above.
  • the tunneling machine according to the invention of the aforementioned type is characterized essentially by the fact that both cutting rollers have to extend a substantially rectangular cutting profile on the profile width end sections.
  • both the top, that is, the positionable at the ridge, as well as the lower, that is positioned on the sole cutting roller extendable end portions the effective cutting width of the cutting rollers on the other by the cutting tools, namely the rotating cutting heads defined Profile width can be increased.
  • the cutting gussets remaining between the individual circular surfaces of the cutting heads can be substantially completely cut away, so that a substantially rectangular cutting profile can be achieved.
  • the quarter-circle-shaped round profiled corners can be cut away, so that in fact a rectangular overall profile can be achieved.
  • the provision of extendable end sections of the cutting rollers provides the possibility of retracting the end sections in turn, so that the cutting roller width is reduced and the maneuvering of the tunneling machine is facilitated in the route.
  • the cutting rollers each have a diameter which corresponds to at least one fifth, preferably at least one quarter of the cutting diameter of the cutting heads. With a correspondingly large diameter of the cutting rollers, a particularly good approximation to the desired rectangular profile shape takes place.
  • the cutting heads are provided with cutting tools which can be displaced or extended in the radial direction. Thereby, the size of the driven by the individual rotating cutting heads circular profile can be adjusted.
  • Another advantage of this design is that the cutting tools, for example, for better maneuverability of the tunneling machine when moving back from the tunnel driven tunnel can be moved radially inwardly to reduce in this way the space requirement and thus the risk of collision with the tunnel walls or the like.
  • the training is advantageously made such that the cutting rollers are height-adjustable articulated on the cutting boom or frame.
  • the drive of the individual cutting units is usually carried out via a central drive and via appropriate transmission.
  • a central drive can be used in the tunneling machine according to the invention, for example, for driving the at least two rotating cutting heads use.
  • the two cutting rollers are each driven separately from each other according to a preferred embodiment, wherein the cutting rollers each have a single drive.
  • the energy consumption for the individual cutting tools can be better coordinated with one another than would be the case with a central drive with drive shafts.
  • central drives have the problem that, when one of the central drive driven cutting units is spinning due to a defect or other unforeseen circumstances, the driving force is automatically distributed to the remaining drive units, which are often not designed for such increased driving force. so that it can be damaged. In the case of individual drives for the cutting units and in particular for the two cutting rollers such problems do not occur because the drive can be controlled separately.
  • a further embodiment is preferred in which the cutting tools are placed on the cutting edge. Heads are arranged such that cutting tools of a cutting head engage in rotation between cutting tools of the other cutting head, so that the circular areas of the respective cutting profiles overlap each other. With such a design, the cutting gussets remaining between the overlapping circular surface profiles are correspondingly smaller, so that the recutting process is simplified.
