Definitions

  • the invention relates to a device for fastening a sealing brush to a tunnel boring machine, with at least two fastening elements arranged on two opposite sides of the sealing brush, with which a retaining plate of the sealing brush is held on a base element. Furthermore, the invention relates to a tunnel boring machine with a base element on which a plurality of sealing brushes are fastened by means of such a device.
  • a generic device is from the DE 26 23 223 A1 known.
  • a corresponding tunnel boring machine is for example in the DE 38 21 754 C2 described.
  • the sealing brushes used in such tunnel boring machines used, for example, for the production of subway or road tunnels seal against the soil and retain groundwater.
  • an additional sealant is introduced into the area of the sealing brushes, such as a suitable sealing grease.
  • the sealing brushes are due to the nature of their use to a certain wear and it is necessary with increasing wear of Abdichtbürsten to introduce a greater amount of the sealant in the range of Abdichtbürsten to ensure adequate sealing.
  • the amount of sealant to be introduced increases with the wear of the sealing brushes, the operating costs of using the tunnel boring machine increase steadily until a point is reached at which it is less expensive to replace the Abdichtbürsten as an ever-increasing amount of the sealant initiate.
  • the sealing brushes on holding plates which are preferably welded at two points with a base element of the tunnel boring machine.
  • these welds must be solved, which is usually carried out by means of cutting and is associated with a very high cost. Since the tunnel boring machine and thus also attached to the sealing brushes are in a very dirty environment, this separation of the welded joints is a very unpleasant and sometimes dangerous work, which is also very time consuming and relatively long downtime of the tunnel boring machine.
  • the holding plate is held by only one of the fasteners by means of a positive connection, which is located on the side of the holding plate of the sealing brush over which a brush head of the sealing brush extends.
  • a positive connection which is located on the side of the holding plate of the sealing brush over which a brush head of the sealing brush extends.
  • the positive connection is provided on both sides of the retaining plate by means of the respective fastening elements.
  • a very simple production of the positive connection results when the at least one positive connection has a holding plate of the sealing brush cross-element.
  • a holding plate cross-over element results in a reliable attachment of the holding plate and thus the entire sealing brush.
  • the holding plate cross-element is designed as the holding plate cross-projection.
  • the holding plate of the sealing brush can be attached particularly easily to the base element of the tunnel boring machine.
  • the holding plate cross-member has an inclined surface which is arranged opposite an inclined surface of the holding plate, that the inclined surface of the cross-member on the Sloping surface of the holding plate rests.
  • the fastening elements are welded to the base member. This represents a particularly simple way to connect the fasteners with the base element.
  • the fastening elements are screwed to the base element. Even by such screwing, the fasteners can be attached to the base element in a simple manner.
  • Fig. 1 shows a very schematic representation of a part of a tunnel boring machine 1, which has a plurality of sealing brushes 2. Furthermore, two supply lines 3 are provided in the present case, with which a sealing means, not shown, can be introduced in a manner known per se into the region of the sealing brushes 2.
  • the sealing brushes 2 seal in known manner concrete slabs 4, which are mounted by the tunnel boring machine 1, opposite to the soil designated by the reference numeral 5, wherein in the present case between the concrete slabs 4 and the soil 5 is liquid concrete 6, with which the concrete slabs 4 on the soil. 5 be attached.
  • a plurality of brushes are arranged side by side in a manner not shown, which together form a closed circle.
  • the tunnel boring machine 1 may be a tunnel boring machine known per se from the prior art.
  • FIGS. 2 to 5 Several embodiments of a device 7 for fastening one or more of the sealing brushes 2 to the tunnel boring machine 1 are shown. From the tunnel boring machine 1 is in the FIGS. 2 to 5 only to recognize a base element 8, on which the sealing brush 2 is attached.
  • the sealing brush 2 has a brush head 9 which is held between two holding plates 10, in the present case a lower holding plate 10 and an upper holding plate 10.
  • the brush head 9 is formed by a plurality of individual wires held between the holding plates 10.
  • the individual wires of the brush head 9 may for example consist of a steel with a relatively high carbon content of about 0.8%, which may additionally have a brass coating in order to improve the corrosion protection of the wires formed therefrom.
  • the tensile strength of the steel used for the individual wires of the brush head 9 may be up to 3,000 N / mm 2 .
  • the device 7 furthermore has two fastening elements 11 and 12 arranged on two opposite sides of the sealing brush 2.
  • the holding plate 10, in the illustration according to the FIGS. 2 to 5 the lower, resting on the base member 8 retaining plate 10 is, by at least one of the fasteners, in the present case by the fastener 12, fixed by means of a positive connection 13 on the base element 8.
  • Fig. 2 and Fig. 3 The embodiments of Fig. 2 and Fig. 3 is common that the holding plate 10 is held by only one of the fastening elements, namely by the fastening element 12 by means of the positive connection 13.
  • This positive connection 13 is located on that side of the holding plate 10, over which the brush head 9 extends.
  • the opposite side of the holding plate 10, ie the side which is connected by means of the fastening element 11 with the base element 8, is in the embodiments of FIGS. 2 and 3 connected by means of a material connection with the fastening element 11, welded in the present case.
  • the retaining plate 10 could also be welded directly to the base element 8 or connected in a materially cohesive manner in other ways.
  • the positive connection 13 a the holding plate 10 cross-element 14 While in the embodiment of Fig. 2 the holding plate 10 cross-member 14 is formed as the holding plate 10 cross-projection 14a, has in the in Fig. 3 illustrated embodiment, the holding plate 10 cross-member 14 has an inclined surface 14b and is formed by this.
  • the inclined surface 14b which is thus located on the fastening element 12, cooperates with an inclined surface 10a attached to the retaining plate 10, so that in the mounted state of the fastening element 12, the inclined surface 14b of the retaining plate 10 cross member 14 on the inclined surface 10a of the holding plate 10th is applied, whereby ultimately the positive connection 13 between the fastening element 12 and the holding plate 10 is formed.
  • FIGS. 4 and 5 show an embodiment of the device 7, in addition to that by the fastener 12 and the holding plate 10th formed form-locking connection 13 between the fastening element 11 and the other side of the holding plate 10 is a positive connection 15 is provided.
  • the formed by the fastening element 11 positive connection 15 also has in the embodiment according to the FIGS. 4 and 5 a holding plate 10 cross-element 16. Both at the in Fig. 4 as well as at the Fig. 5
  • the support plate 10 cross member 16 is formed as a projection 16a, but it would also be possible, if appropriate, a solution analogous to the inclined surfaces 14b and 10a of Fig. 3 provided.
  • the holding plate 10 of the sealing brush 2 is fixed on both sides by means of the respective fastening elements 11 and 12 with positive connections 13 and 15 on the base member 8, both during assembly and during disassembly, the individual Abdichtbürsten 2 under the fasteners 11th or introduced 12 or pulled out during disassembly under the fasteners 11 and 12.
  • a combination of positive connections and cohesive connections is possible to prevent slippage of the individual Abdichtbürsten 2 in the circumferential direction.
  • the attachment of the fasteners 11 and 12 to the base member 8 may, as in the Figures 2 and 5 represented by welding, or, as in the Figures 3 and 4 shown, done by screwing.
