Definitions

  • the invention relates to a cutting wheel arrangement for a trench cutter according to the preamble of claim 1.
  • a cutting wheel arrangement comprises a rotating drivable Fräsradnabe and a Fräsradtrommel which axially aufsteckbar on the Fräsradnabe and detachably coupled to the Fräsradnabe (as for example in document EP-A-1580327 described).
  • Trench wall cutters are known in the art and are used in particular to create in the ground in particular vertically extending slots, which are filled with a curable suspension to form a slot wall.
  • trench wall cutters have a carrier device that can be placed on the ground, which can in particular comprise a chassis for moving the trench wall cutter. Furthermore, a milling frame is provided on which at least one cutting wheel arrangement is rotatably mounted. The milling frame is introduced together with the cutting wheel assembly in the slot to be created in the ground.
  • Milling elements are arranged on an outer circumference of the cutting wheel drum. Since the cutting elements are exposed to considerable wear by the milling process, it is known to attach these interchangeable to the Fräsradtrommel.
  • the invention has for its object to provide a cutting wheel assembly for a trench cutter, which allows a particularly economical operation of a trench cutter.
  • the cutting wheel assembly according to the invention is characterized in that for connecting at least one extending in the radial direction locking element and at least one receptacle are provided with a circumferentially extending receiving slot, wherein the locking element is inserted into the receiving slot by rotation of the milled on the Fräsradnabe Fräsradtrommel relative to the Fräsradnabe ,
  • the cutting wheel arrangement according to the invention enables a particularly simple, safe and fast changing of the cutting wheel drum.
  • a basic idea of the invention can be seen to provide a mechanism with which the Fräsradtrommel can be fixed axially to the Fräsradnabe before its final fixation, so its rotationally fixed connection with the Fräsradnabe.
  • the Fräsradtrommel is first attached axially to the Fräsradnabe and then rotated in the circumferential direction, wherein a locking element in a receptacle, which can also be referred to as a lock, is introduced.
  • a locking element in a receptacle which can also be referred to as a lock
  • the Fräsradtrommel is axially fixed to the Fräsradnabe. In this axially secured position the Fräsradtrommel can then relatively easily against rotation secured against the Fräsradnabe, so rotatably secured to the Fräsradnabe.
  • the milling wheel drum fixed axially on the cutting wheel hub can be fastened in a torque-proof manner to the cutting wheel hub, in particular by means of separate fastening elements, preferably screws and / or bolts.
  • the cutting wheel assembly according to the invention thus enables a simple, safe and fast attachment of the cutting wheel drum to the cutting wheel hub.
  • the insertion of the locking element into the receiving slot can be simplified according to the invention in that the receiving slot and / or the locking element has a wedge shape in the circumferential direction.
  • the wedge shapes of the receiving slot and the locking element are coordinated so that at least one lateral edge of the locking element is supported on a lateral inner surface of the receiving slot, so that a torque between Fräsradnabe and Fräsradtrommel can be transmitted via the corresponding contact surface.
  • the torque transmission surface formed in this way is comparatively large and allows a secure transmission of torque.
  • the cutting wheel drum has a direction of rotation for removing soil material and an opposite direction of idling.
  • the wedge shape is aligned so that the locking element is pressed in a milling operation in which the Fräsradnabe is driven in rotation, due to the forces acting on the Fräsradtrommel forces in the receiving slot, so that on the lateral edge of the locking element and the inner side surface of the receiving slot a Torque can be transmitted.
  • the locking element can be arranged on the cutting wheel hub or on the cutting wheel drum.
  • the receiving slot is located on the respective other part of the cutting wheel assembly. A particularly easy to handle Fräsradanowski is achieved in that the receiving slot is formed on the Fräsradnabe and the locking element on the Fräsradtrommel.
  • the wedge shape is preferably formed in the direction of rotation for removing soil material, ie in the idling direction, tapered. In a reverse Arrangement of locking element and receiving slot, the wedge shape is formed counter to the direction of rotation for removing soil material tapered.
  • the Fräsradnabe has a first stop surface, which forms an axial stop for the Fräsradtrommel and along which the Fräsradtrommel is rotatable for insertion of the locking element in the receiving slot.
  • the first stop surface forms a stop for the locking element.

  • the receiving slot is therefore bounded on the one hand by the first stop surface and on the other hand by a web arranged in front of it or next to it in the axial direction.
  • the first stop surface preferably extends annularly on the Fräsradnabe, while the boundary web or the boundary wall is arranged only on a ring segment.
  • a secure screwing of the locking element in the receiving slot can be achieved in that the first stop surface extends transversely, in particular perpendicular to a rotational axis of the Fräsradnabe, while the wedge shape of the receiving slot is provided by an oblique surface of the limiting web.
  • a simple centering of the Fräsradtrommel can be achieved in that the Fräsradnabe has a second stop surface, which forms a radial stop for the Fräsradtrommel and along which the Fräsradtrommel is rotatable for insertion of the locking element in the receiving slot. Analogous to the first stop surface slides the Fräsradtrommel during insertion of the locking element along the second stop surface in the receiving slot.
