Definitions

  • the invention relates to a screed for a road paver according to the preamble of claim 1.
  • the working width of pavers is usually widened by so-called sliding screeds, which are mounted on the opposite ends of the main screed and can be extended laterally.
  • the storage of the sliding screeds on the main screed must be sufficiently stable so that the sliding screeds do not tilt over the main screed.
  • the invention has for its object to provide a screed that allows the working width to be increased by the full width of each extending screed.
  • the above guide members on the intermediate slides ensure that when the intermediate slides are moved to the ends of the main plank, the guide members assigned to the intermediate slides protrude beyond the outer ends of the main plank.
  • the guiding elements represent "extension arms" of the intermediate slides, which make it possible to move the screeds completely out of the area of the main screed, to the extent that there is no longer any overlap between mutually facing end areas of the main screed and the respective screed.
  • the guide members protrude at least with respect to the outer end plates of the intermediate slides facing the ends of the main screed.
  • the guide members end in the known device of DE 42 08 883 A1
  • the guide members protruding from the outer end plate of the respective intermediate slide according to the invention result in an extension of the guide members of the intermediate slide, with which the extending screeds pass the outer end plates of the main screed are extendable.
  • the guide members are connected to the intermediate slide at opposite ends. In this way, the full length of your guide member is available for moving the screed.
  • the guide members are preferably attached indirectly to the intermediate slides by support members which are firmly connected to the inner and outer end plates of the intermediate slides. End flaps at the ends of the support members serve to fasten the ends of the guide members. This type of attachment makes it possible to attach the guide members to the intermediate slides without twisting them and to move the inner plates of the sliding boards past the outer end plates of the intermediate plates.
  • the figures show a left half of a screed 11 for another paving machine, not shown, viewed from the rear in the direction of production 10.
  • the screed is attached in the production direction 10 behind the paver.
  • the screed 11 is composed of a centrally divided main screed, of which only a left half is shown in the figures. If necessary, both halves of the screed 10 can also be connected to one another.
  • the (left) main screed half 12 is provided with a shifting screed 13.
  • the main screed half (not shown) also has a shifting screed.
  • the shifting screed 13 is supported on the main screed half 12 via an intermediate slide 14.
  • the main screed half 12 and the shifting screed 13 have approximately the same width.
  • the shifting screed 13 can be displaced in relation to the main screed half 12 transversely to the production direction 10, namely extendable into the position shown in FIGS. 1 and 2 and retractable into the position shown in FIGS. In the extended position, the shifting screed 13 doubles the width of the main screed half 12.
  • the main plank half 12 has an outer end plate 16 at its outer end 15.
  • the opposite end of the main plank half 12, which faces away from the longitudinal central axis of the paver, has an inner end plate 17.
  • the end plates 16 and 17 are rigidly connected to one another.
  • the shifting screed 13 has an outer plate 18 and an inner plate 19.
  • the outer plate 18 and the inner plate 19 are also rigidly connected to one another.
  • the intermediate slide 14 has an outer end plate 20 facing the outer end 15 of the main screed half 12 and an inner end plate 21 facing the inner end plate 17 of the main screed half 12.
  • the outer end plate 20 and the inner end plate 21 of the intermediate slide 14 are connected to one another, inter alia, by two support members designed as opposite profile rails 22.
  • the intermediate slide 14 is on the opposite sides of its outer end plate 20 and its inner end plate 21 is mounted on guides 23 fixedly connected to the main screed half 12. As a result, the intermediate slide 14 can be moved transversely to the production direction 10 between the inner end plate 17 and the outer end plate 16 of the main screed half 12. For this purpose, the distance between the outer end plate 20 and the inner end plate 21 of the intermediate slide 14 is less than the distance between the outer end plate 16 and the inner end plate 17 of the main screed half 12.
  • a telescopic guide tube 24 is fastened to the intermediate slide 14, namely between the outer end plate 20 and the inner end plate 21 thereof.
  • An extendable end 25 of the telescopic guide tube 24 is fixedly connected to the outer plate 18 of the shifting screed 13.
  • the shifting screed 13 on the outer plate 18 is guided by the telescopic guide tube 24.
  • a pressure medium cylinder 32 is arranged between the inner end plate 17 of the main screed half 12 and the outer plate 18 of the shifting screed 13 . This serves to retract and extend the shifting screed 13 with respect to the screed half 12, with simultaneous (forcible) taking the intermediate slide 14 with it.
  • the inner plate 19 of the shifting screed 13 is displaceably mounted on guide members 26 and 27 of the intermediate slide 14 designed as guide rods 26 and 27.
  • the guide rods 26 and 27 protrude from the outer end plate 20 of the intermediate slide 14 facing the outer end plate 16 of the main screed half 12 (FIGS. 1 and 2).
  • the extent to which the guide rods 26 and 27 protrude relative to the outer end plates 20 of the intermediate slide 14 is selected such that when the shifting screed 13 is extended, the inner plate 19 of the same is moved outwards relative to the outer wall of the outer end plate 16 of the main plank half 12, so that the entire screed 13 laterally next to that through the outer end plate 16 of the Main plank half 12 formed outer end 15 of the main plank half 12 is (Fig. 1 and 2).
  • the length of the respective guide rod 26 and 27 on the intermediate slide 14 and the length of the respective guide 23 for the intermediate slide 14 on the main screed half 12 together corresponds to the width of the shifting screed 13 or slightly exceeds it.
  • the shifting screed 13 can move out of the main screed half 12 over its entire width, so that the width of the screed when the shifting screeds are fully extended is twice the width of the Main screed corresponds.
  • the guide rods 26 are fastened to the intermediate slide 14 indirectly by means of the profile rails 22.
  • the profile rails 22, which are designed as L-profiles in the exemplary embodiments shown here, are provided at their opposite ends with a front plate 28 or 29.
  • the guide rods 26 and 27 are fastened between the end plates 28 and 29 of the profiled rails 22 by the ends of the guide rods 26 and 27 being connected to one end plate 28 and 29, respectively.
  • the guide rods 26 and 27 are connected via the profile rails 22 to the outer end plate 20 and the inner end plate 21 of the intermediate slide 14. The distance between the outer end plate 20 and inner end plate 21 of the intermediate slide 14 is less than the length of the profiled rails 22 and the guide rods 26 and 27.
  • the profiled rails 22 protrude clearly from the outer end plate 20 facing the outer end 15 of the main plank half 12.
  • the guide rods 26 and 27 also protrude from the outer end plates 20 in a manner similar to a support arm.
  • the distance between the outer ends of the guide rods 26 and 27 relative to the outer wall of the outer end plate 20 of the intermediate slide 14 is slightly more than the thickness of the outer end plate 16 of the main screed half 12 and the inner plate 19 of the shifting screed 13 (FIG. 2).
  • the ends of the profiled rails 22 and the guide rods 26 and 27 held thereon also protrude slightly from the wall of the inner end plate 21 of the intermediate slide 14 facing the inner end plate 17 of the main plank half 12.
  • the ends of the guide rods 26 and 27 and the profile rails 22 can be flush with the wall of the inner end plate 21 of the intermediate slide 14 facing the inner end plate 17 of the main screed half 12.
  • the screed 13 is slidably mounted with its inner end plate 21.
  • the (first) guide rod 26 is provided with a circular cross section.
  • a guide bush 30 corresponding to the cross section of the guide rod 26 is fastened to the inner plates 19 of the shifting screed 13.
  • the (second) guide rod 27 has an approximately square cross section.
  • Opposite (horizontal) guide surfaces 31 of the guide rod 27 are assigned parallel (flat) guide surfaces 31, which are firmly connected to the inner plate 19 of the shifting screed 13 (FIG. 5). Furthermore, FIG.
