  • the invention is also intended to provide a working head for tunneling machines and the like which is particularly suitable for carrying out the method. created, which among other things characterized by advantageous training and possible uses. Further problems connected with all of this, with which the invention is concerned, result from the respective explanation of the indicated solution.
  • the invention provides that the profile enlargement is based on the undercut principle.
  • existing problems with borehole enlargements in particular the generation of an overcut, have been considerably reduced or eliminated and favorable conditions for the execution of the process and the stressing of the elements involved have been achieved.
  • the undercut is an effective working principle in which mostly only the low tensile strength of the rock compared to the compressive strength has to be overcome. It is also important that an overcut or other enlargement of the profile is made possible in this particularly advantageous manner without conversion measures on the drilling head, for example on loading devices.
  • the extent and shape of the profile enlargement, in particular an overcut, can be achieved in the desired manner by appropriately controlling the movement of one or more undercut tools.
  • the working head can be given a feed movement during the generation of the profile enlargement. This includes then of advantage if an overcut is to be produced over a certain section simultaneously with the opening of the main cross section, for example in view of the particular convergence of the mountains.
  • the method can also be carried out in such a way that the working head is given a rotation without movement in the direction of advance during the generation of the profile enlargement. This can include then come into consideration if an enlargement of the profile is to be generated only at a certain point, the working head being able to be set apart from the working face or else still attacking it.
  • the invention furthermore relates to a working head which can be driven in rotation and is provided with tools for working out a circular cross section and has at least one tool which can be moved from the inside to the outside and from the outside to produce a profile enlargement, for a machine for advancing Lines, tunnels or the like, in particular a machine for carrying out the method explained above.
  • the invention provides that the movable profile enlarging tool is an undercut cutting roller. In particular, it is a so-called disc role.
  • a holder for the cutting roller is arranged on the working head in a radially displaceable manner by means of a controllable drive.
  • the drive can be provided laterally by a guide for the holder.
  • the displacement drive is arranged in the displacement direction of the holder for the cutting roller.
  • a holder for the cutting roller can be pivoted by means of a controllable drive about an axis located on the working head.
  • the swivel axis can include be provided in the front area of the working head or in the rear area of the working head.
  • the tunnel boring machine shown in FIG. the following parts: a working or drilling head 1, an inner part 2 (so-called inner kelly), an outer part 3 (so-called outer kelly) with tensioning devices 4 and adjusting cylinders 5, feed cylinders 6, one or more drive motors 7 for the working head 1, a rear one Support 8, a conveyor belt 9 and an anchor boring machine 10.
  • a working or drilling head 1 an inner part 2 (so-called inner kelly), an outer part 3 (so-called outer kelly) with tensioning devices 4 and adjusting cylinders 5, feed cylinders 6, one or more drive motors 7 for the working head 1, a rear one Support 8, a conveyor belt 9 and an anchor boring machine 10.
  • This is only an example of tunneling machines to which the invention can be applied.
  • the working head 1 of such or a similar machine can be designed as shown in FIG. 2. Depending on the design of the machine and the type of operation, it can receive a continuous feed movement and / or a batch movement in the direction of advance.
  • the working head 1 is normally used to work out a circular cross section and for this purpose is provided with center tools 11, with roller drilling tools 12 distributed over its end face and with caliber tools 13. To pick up the loosened pile or small rock, the working head 1 has rotating shovels 14 or the like. on.
  • the letter U designates the outer working contour of the drilling head 1, determined by the caliber tools 13, which is the same as the circular contour of the route traveled on the face is (see also Figures 3 to 5). The diameter of this circular cross section is shown in FIG. 2 at the letter D.
  • the working head 1 is provided with tools 15 at two positions offset by 180 ° from one another, which can be brought from a radially inwardly retracted rest position into a radially outer working position in which their areas intended for attacking the mountains are selectable Project the amount beyond the working contour U of the drill head.
  • These tools are undercut cutting rolls or disc rolls.
  • the lower tool 15 in FIG. 2 is in its radially inner rest position, while the upper tool 15 has assumed a radially outer working position.
  • the movement of both tools 15 is controlled in such a way that they work out a contour denoted by K1, indicated by dash-dotted lines, which results in a so-called overcut.
  • the contour K1 coincides at the lowest point of the working head 1 with the deepest point of the working face or the working contour U of the drilling head, while there is a difference E1 at the highest point between the two. This is the maximum overcut amount.
  • the movements of the two tools 15 are controlled continuously in the course of a rotation of the drill head in such a way that the contour K1 results.
  • a second overcut contour K2 is drawn in as an example in FIG. 2, with a larger difference E2 compared to the circular contour U, which is, for example, twice as large as the overcut amount E1.
  • FIGS. 3 to 5 illustrate some designs for the design and arrangement of a profile rotatable mounted, undercut working disc roller 15.
  • the working head 1 is only shown largely schematically with its supporting structure 16 and without its tools 11, 12, 13 (FIG. 2) which work the face B.
  • the cutting rollers 15 are each shown in FIGS. 3 to 5 in a position moved beyond the normal working contour U of the drilling head 1.
  • a holder 21 for the cutting roller 15 is designed as a double piston 22a, 22b, which is radially displaceable in a cylinder 23. If a pressure medium is supplied to the upper cylinder chamber 23a through a line 24, the piston 22a, 22b with the holder 21 and the cutting roller are displaced radially outward into the position shown. A profile enlargement is worked out when the working head 1 rotates and a feed movement thereof, for example an overcut according to FIG. 2 with the contour K1.
  • Figure 3 is shown by the dash-dotted contour line that the cutting roller 15 in the course of a feed movement of the working head 1 from its retracted rest position can be gradually pushed out to the shown position corresponding to the contour K1.
  • the holder 21 with the cutting roller 15 is pushed in by releasing the pressure medium from the cylinder space 23a via the line 24 and supplying pressure medium to the cylinder space 23b through the line 25, via which pressure medium could flow out in the reverse process.
