Definitions

  • the invention relates to a folding tooth for a cutting wheel with a Swivel bearing, for pivotal holding on a pivot pin on a cutter hub, away from the pivot bearing extending milling tooth holder and one from the pivot bearing essentially opposite to the direction of the Fräsierehalters away extending control arm.
  • folding teeth are known from EP 0 291 027 B1, which also goes back to the applicant.
  • EP 0 291 027 B1 proposed, the adjacent to the bearing plate cutting teeth to store hinged on the cutting wheels.
  • the folding teeth can be in an area below of the milling blade are unfolded to underlying ground area while at a further rotation of the Milling wheel, the folding teeth are folded back, so that The bearing plate is not damaged by the cutting teeth.
  • the folding teeth are by their necessary Tilting exposed to quite considerable forces and loads, especially if harder ground or rocky ground must be edited.
  • the known folding teeth are thus exposed to a very strong wear and can also suffer early damage, which one soon Make replacement necessary.
  • An exchange of the folding teeth leads not only to relatively long and therefore costly downtime the investment-intensive trench cutter, but the folding teeth are because of their necessary pivotal mounting and the required wear resistance relatively expensive.
  • the invention has for its object to provide a folding tooth, which has a simplified manufacturability improved durability.
  • a folding tooth according to the invention is characterized that the pivot bearing, the Fräs leopardhalter and the control arm are formed as a one-piece carrier.
  • the folding tooth can be made by casting or forging, wherein however, a preferred production by flame cutting is given from a sheet metal. Compared to the design as a welded construction results in the one-piece design of the pivot bearing and the individual arms of the folding tooth one improved strength while reducing the Production costs.
  • a preferred embodiment of the invention is in that a receptacle is formed on the milling tooth holder, in which hardened cutting teeth are releasably secured.
  • the integral supports can be the ground breaking cutting teeth made of a specially hardened material.
  • to Connection with the carrier can be conventional non-positive and positive Connecting means and joining methods are used.
  • the Milling belt holder between the pivot bearing and the receptacle for the cutting teeth is formed a taper.
  • Such Rejuvenation allows improved elasticity of the above Milling tooth holder, allowing bending loads in the tapered Job can be recorded and thereby the Swing bearing is relieved.
  • this rejuvenation can also an even better pivoting of the folding tooth on the milling blade allow.
  • the pivot bearing as a single bearing eye be formed by flame cutting or drilling in the carrier has been introduced.
  • the pivot bearing at least two spaced apart Has bearing walls, each with one another Coaxially arranged bearing eye are provided.
  • the warehouse walls can be made by inserting a groove in the one piece Carriers are produced.
  • the bearing eyes can also be made by flame cutting or drilling.
  • a stop element is arranged in the region of the control arm. This serves to make contact with the control arm with the Fräsradnabe on which the folding tooth is mounted. By this stop, the maximum Ausklappwinkel to the end shield limited.
  • the stop element may consist of a highly wear-resistant material, as the folding teeth through the pending soil in operation a considerable pressure on exercise the stopper.
  • a wear plate releasably and replaceably supported.
  • the wear plate serves as a cam follower for contacting of the folding tooth with the control bar on the milling blade, through which Time and extent of the deflection of the folding tooth dependent be predetermined by the rotational position of the cutting wheel.
  • This wear plate functionally exposed to a significant sliding friction.
  • the wear plate therefore preferably has lubricating Metal alloys on which about bronze or brass can contain.
  • the wear plate can be made separately become, whereby the manufacturing costs of the folding tooth reduce overall. With appropriate wear can the wear plate exchanged quickly and inexpensively while the wearer of the folding tooth continues to work on the cutting wheel remains attached.
  • the Wear plate is bolted to the control arm.
  • a Screw is particularly inexpensive to produce and can be easily detached and fastened again.
  • a groove guide between control arm and wear plate is provided.
  • a guide such as a dovetail guide allows a fast and exact arrangement the wear plate on the folding tooth. This allows maintenance times and maintenance costs are further reduced.
  • a Material savings on the wear plate is according to the invention achieved in that the wear plate formed kidney-shaped is.
  • the wear plate on their Side regions is formed chamfered.
  • This bevel which may be straight or curved, allowed a gentle interaction with the control bar, so that the Folded tooth can be folded in and out largely without jerking can. This also has a positive effect on the lifetime of the person Folding tooth off.
  • the folding tooth according to the invention can basically be used on a wide variety of different types Milling wheels are used.
  • a preferred application however, is the use of a trench cutter, as in special foundation engineering for the creation of supporting and sealing walls is used.
  • FIG. 1 the arrangement and the function of an inventive Folding tooth 10 on a bearing plate 5 a Trench wall cutter shown.
  • a bearing plate 5 At the end plate 5 are to two sides each rotatably mounted two cutting wheels, which made For reasons of clarity are not shown.
  • pivot pin 18th At the end of the bearing plate 5 facing side of the cutting wheels are pivot pin 18th arranged on which a folding tooth 10 in a known manner is pivotally mounted.
  • the pivoting movement of the folding tooth 10 is replaced by a fixed to the bearing plate 5 control bar. 7 along which the folding tooth 10 slides along.
  • the operating position is shown in which the Folding tooth 10 is unfolded, leaving the bottom material underneath of the bearing plate 5 can be processed.
  • the structure and the function of the folding tooth 10 are associated with Figs. 2 to 4 explained in more detail.
  • the folding tooth 10 has an integral base body 11, in which a pivot bearing 12 for receiving the at the Fräsradnabe attached pivot pin is provided.
  • a pivot bearing 12 for receiving the at the Fräsradnabe attached pivot pin is provided.
  • the pivot bearing 12 are, as can be seen from Fig. 4, two formed by a groove 15 separate bearing walls 14, in which each bearing eye 16 is drilled out.
  • the two bearing eyes 16 are aligned coaxially with each other, so that the Pivot bolt 18, optionally introduced with a sliding sleeve and so the folding tooth 10 can be pivotally mounted.
  • a so-called Fräs leopardhalter 20 is formed, in which two receptacles 22 introduced for the cutting teeth are.
  • a taper 26th formed so that a total hourglass-like shape on Basic body 11 is given.
  • control arm 30 From the storage area 12 away extends approximately opposite for milling tooth holder 20 a so-called control arm 30, which also integrally formed on the base body 11. At the free end of the control arm 30 is an approximately kidney-shaped wear plate 34 detachable and replaceable by means of screw 36 attached. The wear plate 34 will be below described in more detail in connection with FIG. 5.
  • FIG. 5 shows the kidney-shaped Front surface 38 of the wear plate 34, being laterally on connect a chamfer 40 bevels 42.
  • the bevels 42 serve for a smooth, smooth gliding the Wear plate 34 along the control bar 7 on the bearing plate 5th
  • a guide groove 44 indicated On the side facing away from the front panel 38 back is schematic a guide groove 44 indicated, which for easy and accurately posting the wear plate 34 to the folding tooth 10 serves. Furthermore, at the back are in an upper area two schematically indicated threaded bores 46 are provided, which for screw mounting the wear plate 34 on Base body 11 serve. In the area of the threaded bore 46 are for wear protection and to ensure a sufficient Strength material heaps 48 provided.
