Definitions

  • the invention relates to a screed for a paver according to the preamble of claim 1.
  • Asphalt pavers are usually provided with a base screed and with two screeds, the latter being extendable to one side of the paver according to the width of the material to be installed. However, widening to twice the width of the base screed is prevented by the necessary guidance and support of the extension screeds.
  • the object of the invention is to provide a screed according to the preamble of claim 1, which makes it possible to widen practically half the width of the base screed on each side.
  • the screed shown comprises a basic screed 1 of a predetermined width, which is arranged on a paver and is connected to two central upright cheeks 2, the main planes of which extend in the direction of travel of the paver.
  • the two extension cylinders 3 are used to extend extension screeds 4, which are arranged behind the base screed 1 in the retracted state and have half the width of the base screed 1.
  • the extending screeds 4 are each provided with an outer displaceable cheek 5, on which the respective extending cylinder 3 engages, and with an inner displaceable cheek 6.
  • the outer cheek 5 is connected to the inner cheek 6 via at least one guide rod 7.
  • the cheek 6 receives a bearing bush 8, which engages around the extension cylinder 3 in the region of its outer tube 3, slidably receives and guides.
  • the extension cylinder 3 is fixedly connected at the outside end of its outer tube 3 'via a flange 3' with a sliding block 9, which in turn can comprise two plates 10 connected to one another and parallel to the cheek 2 and is provided with guide bushings 11 for the guide rod (s) 7 .
  • the flange 3 ⁇ is aligned with the extended screed 4 with the outer edge of the base screed 1.
  • the respective side cheek 12 of the base screed 1 carries a guide 13, which extends in the area above the base screed 1 at least over the width of the sliding block 9 and outwards at least by the width of the sliding block 9 plus that for extending the extending screed 4 by half the width of the
  • the basic screed extends the necessary route.
  • the sliding block 9 can be moved along the guide 13 by means of a cylinder 14 which acts between the cheek 2 and the sliding block 9.
  • the guide 13 has two strips 15, which extend parallel to the extension direction of the extension screed 4, with mutually facing lateral guide grooves 16, the guide 13 receiving a guide plate 17 on the underside of the sliding block 9, which is profiled laterally in accordance with the guide grooves 16.
  • the sliding block 9 or its guide plate 17 (or guide strips arranged at an appropriate distance from one another) is sufficiently wide to ensure good guidance when adjusting the sliding block 9.
  • the extension cylinder 3 extends the extension screed 4 sideways relative to the pusher 9 by a predetermined stroke H with respect to the paver, whereby the inner cheek 6 comes close to the inside of the pusher 9.
  • the sliding block 9 - and with this the extending screed 4 and the extending cylinder 3 - is pushed sideways outwards by the cylinder 14 in the guide 13, so that the extending screeds 4 can be extended by half the width of the basic screed 1, so that the extending screeds 4 can double the basic screed 1 in width. If necessary, too Stops to limit the displacement path of the sliding block (9) may be provided.
  • the axes of the extension cylinder 3 and the guide rod (s) 7 can expediently be offset from one another in the vertical direction in order to achieve greater stability and rigidity.
  • the cylinders 3, 14 can have a sequential circuit for successive opening and closing, but this can also be dispensed with. Then the cylinder with the lowest section modulus first moves in or out.
