Definitions

  • the invention relates to a cutting wheel for a trench cutter according to the preamble of claim 1 and to a method for creating a trimming slot in a floor according to the preamble of claim 14.
  • the cutting wheel comprises a drum-shaped basic body, on the outer circumference of which fixed supports are arranged in at least one circumferential row, in which milling tools for removing soil are received.
  • EP 2 020 462 A2 shows a trench cutter with multiple cutting wheels, which are equipped with cutting teeth.
  • the trench wall cutter is therefore particularly suitable for removing soft floors.
  • a equipped with chisels cutting wheel is in the EP 2 060 375 A1 described.
  • the invention has for its object to provide a cutting wheel and a method for creating a Frässchlitzes in a soil, which allow a particularly economical and fast creation of the slot.
  • milling tools with a substantially point-shaped removal tip as well as cutting teeth with a substantially linear cutting edge are arranged as milling tools.
  • a trench wall cutter with at least one cutting wheel formed in this way is introduced into the ground and the ground is removed by the milling tools.
  • a first basic idea of the invention can be seen in providing on the cutting wheel both milling tools for targeted removal of soft soil and milling tools for targeted removal of hard soil.
  • the cutting wheel according to the invention is therefore suitable for milling through different soil layers, without the need to replace the milling tools in the transition between the soil layers.
  • the chisels and the cutting teeth are stored in separate receptacles or holders.
  • a point load is generated on the material to be removed, in particular hard material such as rock, which leads to a chipping or blasting off of the material.
  • Soil removal is carried out by a breaking process.
  • the cutting or milling teeth are suitable for penetration into soft soil, so that a soil removal essentially takes place by means of a cutting process.
  • the chisels may in particular be round shank chisels which have a shank with a round cross section.
  • the round shank bits can be rotatably mounted in a bit holder, which is preferably designed as a hollow cylindrical bore.
  • the shank of the bit may also have a different cross-sectional shape, for example a polygonal cross-sectional shape.
  • a second basic idea of the invention is to arrange the milling tools, which are each adapted to a specific soil condition, in a common circumferential row or in a common circumferential line around the drum-shaped basic body.
  • the holders for the chisels and for the cutting teeth of a circumferential row in this case preferably lie in a plane perpendicular to the axis of rotation of the cutting wheel. This is based on the knowledge that due to the specific designs of the bit and the cutting teeth excessive wear of the milling tools can be avoided if the bit and the cutting teeth are arranged in the direction of rotation of the cutting wheel behind the other, so cover substantially the same circular line. With a correct rotation of the cutting wheel, the chisels automatically perform a greater removal work on hard rock strata than the cutting teeth. On the other hand, in softer, especially cohesive soils, the cutting teeth take over a large part of the soil erosion. This can be with the cutting wheel according to the invention without replacing the milling cut through both hard and soft soil layers.
  • a cutting tooth in a Abtragsnavraum the cutting wheel at least one bit is disposed in such a way that the Scheid leopard is arranged in a Abtragsschatten the at least one bit.
  • the cutting tooth is therefore preferably arranged at the same axial height of the cutting wheel in the circumferential direction behind the bit, so that the cutting tooth moves off an already swept by the bit ring surface.
  • the stone is loosened by means of the chisel by breaking or knocking off the material.
  • the punctiform Abtrags rotate beyond a large-scale removal of material by chipping off of the material. Due to the punctiform erosion point of the chisel, therefore, sufficient material is usually removed during rotation of the cutting wheel, so that the cutting tooth with the cutting edge does not or only slightly engages with the pending ground.
  • a cutting tooth in a Abtragsnavraum of the cutting wheel are preceded by a plurality of chisels, which are aligned at different angles of attack.
  • the cutting edges of the cutting teeth preferably extend in an axial direction of the cutting wheel, so that a blade-like soil removal of soft soil material can take place.
  • the punctiform erosion tips of the chisel each only cover a comparatively narrow line.
  • the individual bits located in front of the respective cutting tooth are differently set or inclined in the axial direction, so that soil removal lines axially offset from one another by the individual bits are swept over.
  • the cutting tooth is set axially.
  • the upstream bits are preferably adapted to the corresponding orientation of the angled cutting tooth.
  • a particularly reliable wear protection of the cutting tooth and an effective soil removal in hard rock is achieved in that in the at least one circumferential row of a group of chisels is formed from at least three bits, with a first bit largely aligned radially, a second bit in an axial direction of the Cutting wheel is angled sideways and a third bit in an opposite Axial direction is angled laterally.
  • the chisels of the group are preferably arranged directly one after the other in the direction of rotation in front of a cutting tooth. Due to the different angles of the chisel, the removal area in the axial direction of the cutting wheel is increased and, in particular, a so-called full cut can be achieved, in which substantially the entire axial extent of the cutting wheel can be removed along the ground.
  • a cutting tooth in a Abtragsnavraum is at least one bit ahead, the Abtragsspitze of the bit relative to the cutting edge of the cutting tooth protrudes defined in the radial direction.
  • the distance between the removal tip of the bit from the axis of rotation of the cutting wheel is thus greater than a maximum distance of the cutting edge of the cutting tooth from the axis of rotation.
  • the cutting teeth are preferably displaced radially back by an amount relative to the bits, which is in the range of a few millimeters to centimeters. Be particularly advantageous, an amount between 5 millimeters and 3 centimeters, in particular between 1 centimeter and 2.5 centimeters has been found.
  • a sheet metal ring is welded, in which the chisel and the cutting teeth of a circumferential row are arranged.
  • the metal ring thus carries the different milling tools in the form of chisels and cutting teeth and ensures the arrangement of the cutting teeth and the chisel in a line or circumferential row around the main body of the cutting wheel.
  • the sheet metal ring extends in a direction perpendicular to the axis of rotation of the cutting wheel level. It may be formed in one piece or from a plurality of sheet metal ring segments, and between individual sheet metal ring segments also free spaces or distances may be formed.
  • the sheet metal ring has radially open first recesses which are adapted to receive the chisel, and radially open second recesses which are adapted to receive the cutting teeth.
  • the first and second recesses are designed differently and tailored to the cutting teeth or the chisel.
  • the recesses for the cutting teeth may have a U-shape to receive cutting teeth with a U-shaped mounting portion.
  • the recesses for the flat teeth can be provided in the circumferential direction inclined recesses.
  • the recesses for the flat teeth are in this case preferably more inclined in the circumferential direction than the recesses for the chisel.
  • the cutting teeth or the chisels can be attached either directly or with additional holders, adapters or sockets in the recesses of the sheet metal ring.
  • receiving bushes are used for releasably holding the chisel and / or the Scheidzähne in the sheet metal ring.
  • the receiving bushes preferably have an insertion opening for receiving a shank of the milling tool.
  • the receiving shells can have round receiving openings.
  • the receiving bushing can in particular provide a sliding bearing for a chisel in which a bearing shank of the chisel is rotatably mounted about its longitudinal axis extending through the ablation tip.
  • the receiving bushes preferably have a dome-shaped base surface for attachment in either different orientations on the sheet metal ring.
  • an ejection opening can be formed on the receiving bush, which communicates with the receiving opening.
  • the milling tool can be driven out of the receiving socket.
  • the individual receiving bushes in particular for the chisels, are arranged in different orientations in the sheet-metal ring.
  • the different orientations may relate to axial and / or radial angles of attack.
  • the receiving sockets are preferably releasably attached to the sheet metal ring. For example, the receiving sockets welded to the sheet metal ring or pressed into these, where they must be knocked out for replacement.
  • the flexibility of the cutting wheel can be further increased by arranging different types of cutting teeth in the at least one circumferential row. For example, cutting teeth for sandy soils and cutting teeth for cohesive soils can be used on the one hand. It is also conceivable to provide cutting teeth for gravel soils or softer rock layers.
  • On the outer circumference of the drum-shaped body is preferably formed a plurality of circumferential rows.
  • exclusively chisels are arranged in at least one axially outer circumferential row, preferably in both axially outer circumferential rows.
  • the chisels are preferably employed at least predominantly axially outward.
