Definitions

  • the invention relates to a trench cutter according to the Preamble of claim 1.
  • Trench wall cutters are used to manufacture trench walls for building pit securing, sealing and foundations.
  • the invention has the object of providing a trench cutter with cylindrical Abtragwerkmaschineen whose bearings have a particularly long service life.
  • the roller axis is substantially radial is directed to the axis of rotation of the cutting wheel, and that a Shell surface of the roller on one facing away from the gear shield Face of the milling wheel opposite this in Protrudes in the direction of the axis of rotation of the milling wheel.
  • the roller can basically have a smooth surface be formed, so to a desired compression the side wall of the sunk slot leads.
  • a preferred one Embodiment is that the roller with removal devices, such as cutting teeth, is provided.
  • the roller is also used as a removal tool Ground breaking trained. There can be a slot with it well-defined walls.
  • the removal tools are roller chisels.
  • the removal tools are frustoconical are.
  • the respective Axis of rotation of the cylindrical removal tool from an axially parallel position to the axis of rotation of the milling wheel be, so that continue through the removal tools with the cutter wheel rotating, a cutter wheel cutting surface is formed that runs parallel to the axis of rotation of the milling wheel.
  • Another embodiment according to the invention exists in that a total of four rollers are provided on a milling wheel are over the milling wheel at predetermined angular intervals are distributed. By the arrangement of several rollers reduces the load on the individual roller. Preferably the rolls are uniform Angular distance or alternately at an angle of 60 ° and 120 ° offset from each other.
  • a total of four milling wheels are provided, two of which are on one side of the shield are arranged.
  • FIG. 1 In the schematic view of Figure 1 is an inventive Trench wall cutter 10 with one of two shield walls 12, 13 constructed transmission shield 11 shown.
  • the Gear shield 11 is not in the usual way on one shown milling frame attached.
  • On both sides of the Gear shields 11 are each a milling wheel 20a and 20b arranged, which by a conventional drive device an essentially horizontally directed axis of rotation 21 are driven in rotation.
  • inner roller bits 22 and outer roller chisel 23 provided as removal tools.
  • the inner roller chisel 22 and the outer roller chisel 23 have truncated cone-shaped roller bodies on the outer surface Removal devices 28 are attached.
  • the inner roller chisels 22 and the outer roller chisel 23 by means of a star arranged brackets on the circumference of the milling wheels 20a, 20b rotatably held.
  • the axes 24 of the inner roller chisel 22 and the axes 25 of the outer roller chisel 23 are substantially axially parallel to the axis of rotation 21 of the Milling wheel 20a, 20b, depending on the taper angle frustoconical roller body of the inner roller chisel 22 or outer roller chisel 23 a certain angle is provided.
  • the angle adjustment is included chosen so that the roller chisel when the cutter wheel 20a, 20b is rotating 22, 23 a ground-contacting cutting wheel cutting surface form, which are essentially axially parallel to the axis of rotation 21 of the milling wheel 20a, 20b.
  • the touch surfaces the enveloping surfaces of the outer roller bits 23 and Envelope surface of the slot 41 are substantially parallel to each other and parallel to the axis of rotation 21 of the milling wheels 20a, 20b arranged.
  • roller axes 27 are essentially radial to the axis of rotation 21 of the milling wheel 20a, 20b and parallel to the shield walls 12, 13 of the gear shield 11 directed.
  • the rollers 26 are star-shaped on the corresponding Milling wheel hub arranged brackets attached so that a The lateral surface of the roller 26 continues in the horizontal direction protrudes from the gear shield 11 as the peripheral surface the outer roller chisel 23. So while the outer roller chisel 23 first a slot at a predetermined Milling width with a side wall 43, this is by the Rollers 26 provided with a widening 44. The broadening 44 depends on how far the rollers 26 face each other protrude the outer roller bits 23. In the shown Embodiment are the rollers 26 themselves with removal devices, such as milling teeth, which are only indicated schematically.
  • rollers 26 on each milling wheel 20a, 20b the lateral forces provided.
  • the total of four rollers 26 are alternately at an angular distance of 60 ° and 120 ° distributed over the circumference of the milling wheel 20a, 20b.
  • This arrangement is for both opposite milling wheels 20a, 20b the same, with the opposite cutting wheels 20a, 20b arranged on the axis of rotation 21 rotated relative to one another are so a particularly good support of the To ensure trench wall cutter 10 in the sunk slot 41.
  • only two cutter wheels 20a, 20b are shown are, the described embodiment of the invention a total of four milling wheels, the two opposite one another are arranged side by side.
