Definitions

  • the invention relates to a roller chisel for tunnel boring machines.
  • Known tunnel boring machines are with cutting heads and roller chisels equipped with cutting elements, e.g. Cutting pins, load-bearing cutting rings are provided, which consist of one part. These cutting rings are on the Cutting body pressed on, shrunk on or by means of a circlip and groove secured. Furthermore, cutting rollers without cutting rings are known, in which Cutting pins are soldered or shrunk directly into the base of the roller chisel are. The cutting rings and the cutting rollers provided with cutting pins can have different profiles.
  • a disadvantage of the known designs is that if necessary Repair of the complete roller chisel or its cutting ring in the Whole must be replaced, even if only a part of the Cutting ring is affected. This causes long repair times, as well as one Technically unacceptable effort, because the roller chisel from the Drill head must be removed completely to carry out such a repair to be able to.
  • the invention is therefore based on the object of a generic roller chisel for tunnel boring machines to create the disadvantages of the known avoids technical solutions.
  • the cutting ring consists of at least two or there are more segments that are interchangeably attached to the roller base are. This makes it possible for the cutting ring itself or worn Renew parts of the cutting ring in segments, without the disassembly previously required and assembly of the complete roller chisel from the drill head with the associated transport costs. The total advance time is thus minimized by shorter repair times because the segments of the cutting ring are in front Location can be changed. The material costs are also reduced.
  • the segments of the cutting ring can be positively preferably with a dovetail guide or T-slot and adapters arranged on the roller base body in a determined position and by means of screwable Segment brackets and / or by means of threaded rings with the roller base be connected.
  • Figure 1 shows an example of a cutting ring 1 from four segments 2.
  • the number of segments 2 can be between two segments 2 and several segments 2 are located according to the respective application.
  • the cutting elements 3 for example carbide cutting pins used.
  • the cutting rings 1 can be arranged so that they are available in one, two or more lanes are, i.e. it can optionally several cutting rings 1 in parallel side by side arranged on the roller base body 4 recognizable in the following figures be.
  • the diameter of the cutting rings 1 in not shown Ascending from the first to the subsequent cutting rings 1 graded can be chosen so that the cutting roller has a conical shape receives.
  • FIG. 2 shows the arrangement of a 2-track cutting body with attachment the roller base 4, in a sectional view. It can be seen that in The circumference of the roller base 4 has a dovetail-shaped recess is incorporated. In the central area, this recess is wedge-shaped Axis offset. There is a thread in this wedge-shaped center provided, in which a screw 6, a clamping element 7 is screwed is after the cutting rings 1 in the dovetail guides worked out on both sides were introduced. Both are in this arrangement Cutting rings 1 over surfaces by the clamping element 7 against the inside of the Dovetail guide securely and firmly clamped. By loosening the screw 6 and removal of the tensioning element 7 are the segments 2 of the cutting rings 1 easily removable and replaceable on site with little effort.
  • FIG. 3 shows the arrangement of a 3-track cutting body with a screw connection shown.
  • the outer cutting rings 1 in turn engage outwards the dovetail guide and have a collar 8 on the Scope of the roller base body 4 rests.
  • the inward facing profiles of the outer cutting rings 1 are continuously wedge-shaped, so that the middle Cutting ring 1 ', which is wedge-shaped on both sides, between the two outer Cutting rings 1 is arranged.
  • a through hole is provided for a screw 6 with which the outer Cutting rings 1 over the middle cutting rings 1 'against the dovetail guide of the roller body 4 are firmly and securely clamped.
  • the shape of the Tension rings 1,1 ' secure the individual segments 2.
  • Figure 4 shows another embodiment of a 2-track cutting body with a dovetail guide arranged at the bottom on the roller base 4.
  • the segments 2 of the cutting ring 1 are recessed on both sides Provide dovetail guides so that their inward-facing surfaces enclose an intermediate ring 9 provided with such a counter profile.
  • the lower cutting ring 1 is on the guide of the basic roller body 4 created. This is followed by the intermediate ring 9 and the upper cutting ring 1.
  • a clamping nut 10 the plan side from above on the Roller body 4 is screwed on, secures the segments 2 of the cutting rings 1 against the roller body 4 by tightening it positively and non-positively.
  • cutting ring 1 does not have individual cutting elements, but rather forms a circumferential when assembling the individual segments 2 Cutting ring.
  • the individual segments 2 are in turn by a clamping nut 10 held on the roller base 4.
  • Figures 6 and 7 show a special embodiment of a cutting ring 1, in which the individual cutting elements 3 are not soldered into the segments 2 or shrunk, but releasably connected to them. This makes possible to take even better account of partial wear and tear on individual segments 2, by then not the entire segment 2, but only the worn ones Cutting elements 3 must be replaced. This will make even fewer Repair and maintenance times and further reduced material requirements reached. The required driving time of the roller chisel can therefore go even further be reduced.
  • the releasable connection the cutting elements 3 with the segments 2 achieved in that the Cutting elements 3 are chisel-shaped with a chisel shaft 11, the engages in a corresponding receptacle 12 of segment 2.
  • the chisel shafts 11 of the cutting elements 3 of the embodiment shown in FIGS. 6 and 7 are cylindrical and in the also cylindrical receptacles 12 secured by clamping elements. As shown, these can be used as clamping sleeves 13 on the chisel shaft 11 and / or in the receptacle 12.
  • recesses 16 are introduced through which a shoulder region 14 of the Cutting elements 3 are gripped by a suitable tool and that Cutting element 3 can be pushed out.
  • FIG. 3 Shape with conical chisel shafts 11 and correspondingly conical receptacles 12.
  • the cutting elements 3 so clamped can be inserted into the Cutting rings 1 corresponding bores 15 pressed out for replacement become.
  • chisel shank 11 and holder 12 can be used in all selected connection types with coordinated holes for one Locking pin. This configuration is also the only connection with cylindrical chisel shafts 11 and receptacles 12 without a clamping element possible.
  • the cutting rings 1 can be segmented according to the invention made of different materials, for example steel, cast steel, chilled cast iron or Tungsten carbide exist. A pairing of materials is also possible, e.g. the Cutting rings 1 made of steel and the associated cutting elements 3 Carbide are made. With chisel-shaped cutting elements 3, these can uniform e.g. consist of hard metal or of different materials, for example, a chisel shaft 11 made of steel and a chisel head made of hard metal put together.
