Definitions

  • the invention relates to a device for fastening disks in cutting wheels of a tunnel boring machine.
  • the disks are rotatably attached to the surface of a tool carrier and are cheaper for certain stone properties in terms of wear than rigid chisels.
  • the disks are also subject to wear on their circumference and to maintain the contour accuracy at the circumference of the borehole in cutting wheels of a tunnel boring machine, disks must be replaced if they are worn by about ten millimeters, otherwise the accuracy of the contour can no longer be guaranteed.
  • the first problem for changing disks is that the storage or the components for locking and fastening the disks should be accessible from the side facing away from the face when there are long downtimes and a procedure of the tunnel boring machine when changing from Discs in cutting wheels should be avoided.
  • the disks have to be changed from the working face.
  • the known devices for attaching disks in cutting wheels were not readily suitable for enabling readjustment or adjustment of the bearing. In particular, it was not possible with the known designs to readjust from the side of the drill head facing away from the working face.
  • the device according to the invention for attaching disks of the type mentioned essentially consists in that the cutting wheel has axially parallel recesses through which the disks and bearing parts can be pushed, that the bearing parts have an eccentric outline relative to the bearing axis of the disks, that on the face facing the side, in addition to the recess for the bearing parts, recesses are provided for supporting the bearing parts on part of their circumference, and that the bearing parts can be fixed in a rotationally fixed manner in at least two different rotational positions by at least one wedge in the recesses.
  • the design is such that the bearing parts have a polygonal outline, the corners of which are arranged at different distances from the bearing axis of the disks, the fact that the bearing parts have a polygonal outline, in which the corners are at different distances are arranged from the bearing axis, different positions can be set by rotating the bearing parts, the adjustment of the disks being carried out in stages.
  • the polygonal outline makes it possible, when interacting with a wedge-shaped locking member, to achieve a simple, non-rotatable fastening, which cannot lead to an adjustment of the selected adjustment even under high loads.
  • the design according to the invention is such that the wedges are connected to tie rods which pass through the axially parallel recesses and interact with tendons on the side of the cutting wheel facing away from the face, such wedges as well as the bearings through the axially parallel recesses of the Side facing away from the face can be introduced.
  • the design is advantageously made so that the clear width of the axially parallel recesses is greater than the smallest width of the bearing parts and as the largest cross-section of the wedges transverse to the tie rod, which ensures that the bearing parts are in at least one rotational position and in At least one installation position of the wedge, both the bearing parts and the wedges can be passed through the axially parallel recesses, whereupon the locking in the respectively selected position can take place by tightening the wedge from the side of the cutting wheel facing away from the face.
  • the wedge is pressed against the eccentric shaft when tensioning from the face side, whereby the bracing can take place by means of a screw connection on the side facing away from the face face, which ensures that the entire cutting forces are transmitted directly from the disc to the disc bearing.
  • a loosening of the wedge connection by forces that occur during operation is excluded by such a design.
  • the bearing housing for the disc in the form of a corresponding polygonal recess enables secure, rotationally locking locking by the wedge and also enables the disc bearing to be guided through the axially parallel recesses of the cutting wheel by lateral displacement of the disc bearing.
  • the disks can thus be removed to the side of the drill head facing away from the working face, and both an adjustability and an assembly of the drilling tools from the side of the cutting wheel facing away from the working face are made possible in a particularly simple manner. At the same time, all cutting forces are dissipated directly into the bearing housing and thus into the cutting wheel.
  • FIG. 1 shows a schematic sectional illustration through a partial area of a cutting wheel with a disc in a working position
  • Fig. 2 is a section along the line II-II of Fig. 1
  • 3 shows a first expansion position with the wedge connection disassembled for removing the disc storage
  • FIG. 4 shows an illustration similar to FIG. 3, in which the bearing parts for discs are shown in their position required for the exchange of the discs.
  • Fig. 1 the circumference of a disc is indicated schematically by 1 and the disc is fixed in a cutting wheel 2.
  • the bearing parts with a polygonal outline are designated by 3 and are in a recess 4, which on an axially parallel recess 5 then pressed using a wedge 6. Due to the polygonal outline of the bearing parts 3, a non-rotatable locking in the recess 4 is ensured by the wedge 6, whereby after loosening the wedge 6 and rotating the bearing parts 3 different positions of the axis 7 of the disc can be set.
  • the formation of the polygonal outline of the bearing parts 3 is eccentric to the axis 7, so that when the bearing parts 3 are rotated, the axis 7 comes into different positions, which enables adjustment.
  • the mounting of the bearing parts 3 via the wedges 6 is carried out using tie rods 8, which are supported against clamping brackets 9 on the side 10 of the cutting wheel 2 facing away from the face, wherein the wedges 6 can also be released from the side 10 of the cutting wheel 2 facing away from this face .
  • the pull rod 8 is shown unscrewed from the wedge 6, whereby the clamping bracket 9 is also free.
  • the bearing parts 3 of the disc 1 can be rotated or brought in the direction of arrow 11 into a position aligned with the axially parallel recess 5 and likewise pulled out in the same direction as the tie rods 8 to the side of the cutting wheel facing away from the face.
  • FIG. 4 This position, in which an exchange of the disks 1 is readily possible, is illustrated in FIG. 4. It is essential here that the clear width a of the opening 5 is greater than the smallest width b of the bearing parts 3, in order to remove it in the axial direction at least in a rotational position of the bearing parts 3 to enable the side 10 of the cutting wheel 2 facing away from the working face.
