Definitions

  • the invention relates to a device for applying a Binder for an asphalt surface on a traffic area with an asphalt paver, with one carried by the asphalt paver's chassis, one Downstream distribution device for the asphalt mix Screed for compacting and smoothing the installed asphalt mix and with one connected to a storage container for the binder, the distributor for the asphalt mix upstream, with spray nozzles equipped spray bar, a middle part and extendable side parts includes.
  • Paving an asphalt surface in a street bed will be better Adhesion of the asphalt mix before application of the asphalt mix a binder sprayed onto the street bed.
  • Asphalt paver known (US 5 279 500 A)
  • the distribution device a spray bar for applying the asphalt in the direction of travel Binder is upstream, so that the asphalt material on the immediately before binder sprayed onto the street bed is applied before the in Asphalt mix installed in this way through a downstream screed is compressed and smoothed.
  • US 5 324 136 A the spray nozzles of Spray bar to move transversely to the direction of travel.
  • a Spray bar with a frame-fixed middle part and extendable side parts intended. While in the area of the middle part fixed to the frame on a Spray nozzles arranged transversely to the direction of travel are merely arranged are moved over a spray area that cannot be changed in width, the extendable side panels can be adjusted with regard to the extension length be what adapting the entire width of the spray area to different Conditions allowed.
  • a disadvantage of this known device for applying a binder to a traffic area is that through the spray nozzles, which can be moved back and forth across the direction of travel none of the middle part and the side parts of the spray bar sufficiently precise dosing across the entire width of the spray area can be ensured.
  • the cross to the direction of travel Asphalt paver movable side parts of the spray bar additional Installation space in the longitudinal direction that is not readily available.
  • Binder for an asphalt surface is also known (EP 971 072 A1) to apply the binder through spray nozzles that are intermittent can be switched on and off.
  • the invention is therefore based on the object of a device for Applying a binder for an asphalt surface on a traffic area the type described in such a way that with simple structural Measures to adapt to different working widths of the asphalt paver is possible without having to apply an exact dosage of the To do without the binder.
  • the invention solves the problem in that the extendable Side parts of the spray bar one led around a pulley and through the Deflection roller in a along the long side of the chassis and one transversely running strand subdivided link chain have that the transverse to each side of the vehicle running side of the link chain of the two extendable side parts of the spray bar on an extendable side part the screed attacks while the along the long side of the vehicle frame extending chain center is connected to a return drive, and that the link chains carry individually controllable spray nozzles.
  • the extendable Side part of the screed drive-connected strand of the link chain with the spray nozzles associated with this chain center the effective extension of the forms a central part of the spray bar, there is a spray bar, the total length of which is determined by the screed Working width of the asphalt paver is adjusted. That for the respective extension of the spray bar with the associated nozzles runs on the long side of the chassis frame, which is advantageous Construction creates relationships because of the for the fixed middle part of the Installation space provided for the spray bar does not additionally accommodate the extendable side panels must be used.
  • the screed can be adjusted in height using swivel arms stored on the chassis of the asphalt paver, it is recommended that the side parts of the spray bar on the swivel arms of the screed, to avoid special design measures for length compensation between the chain center running transversely to the direction of travel and the screed to have to provide for their height shift.
  • the viscosity of the binder is advantageous for spraying can be ensured, the binder must be warmed up accordingly.
  • the storage container for the binder on the screed facing wall or on the asphalt paver to provide arranged tipping trough into which the hot to be processed Asphalt mix is brought in to be discharged over a scraper floor the distributor device downstream of the spray bar, usually one Auger to be fed.
  • the binder can thus be heated in the storage container so that to reach the desired binder temperature, the binder only can be warmed up with a comparatively small amount of heat got to.
  • the device for applying a binder for an asphalt surface on a traffic area is built on an asphalt paver, the one Chassis 1 with one arranged at the front end of the chassis 1
  • Tipping trough for the hot asphalt mix has a scraper floor discharged from the tipping body and a distribution device in the form a distribution screw is fed, but for reasons of clarity is not shown.
  • a spray bar 2 is arranged upstream of this distributor device, that of a central part 3 indicated by dashed lines in FIGS. 2 and 3 and extendable side parts 4 and the distance between the middle part 3 and bridging the side parts 4 in the area of the wheels 5 of the asphalt paver Spray nozzles 6 there.
  • a screed 8 is arranged downstream of the distributor device in the direction of travel 7, which is mounted on swivel arms 9 on the chassis 1 and with With the help of a swivel drive 10, for example a swivel cylinder, the Height can be adjusted.
  • the screed 8 is extendable Provided side parts 11, the guide rods 12 in a frame 13th of the middle part of the screed 8 slidably mounted transversely to the direction of travel 7 are.
  • the screed 8 is with sliding plates 14 for compacting and smoothing the asphalt mix installed in a road bed via the distribution device Mistake.
  • the side parts 4 of the spray bar 2 are each connected by a link chain 15 formed, which is guided around a deflection roller 16.
  • This pulley 16 divides the link chain 15 into one along the long side of the chassis 1 running chain center 17 and a chain center 18 running transversely thereto. While the chain center 18 on a side plate 19 of the respective side part 11 of the screed 8 is articulated, the free end of the chain center engages 17 on a return drive 20, for example from an actuating cylinder 21 for a pivot lever 22, on which in turn a connecting link 23 is supported at the end of the chain center 17.
  • This chain end is in a sliding guide 24 extending in the direction of travel 7, the Carrier 25 also receives the deflection roller 16.
  • the link chain 15 is deflected around the deflection roller 16 taken against the return drive 20, which is transverse to Direction of travel 7 extending chain center 18 extended accordingly. Since on the individual chain links of the link chain 15 spray nozzles 26 are arranged, which can be controlled individually results from the nozzles in the Region of the respective chain center 18 an extension of the nozzle bar 2 to the extent of the adjustment of the side parts 11 of the screed 8.
  • the nozzles 26 in the area of the chain center 18 thus form together with the nozzles 6 and the nozzles 27 of the middle part 3 of the spray bar 2 a row of nozzles, the one has uniform nozzle spacing transversely to the direction of travel 7, which with matching Spray nozzles 6, 26 and 27 are an essential requirement for an even distribution of the binder over the respective working width of the asphalt paver. Because the amount of binder sprayed through the spray nozzles with given spray nozzle dimensions and a given Viscosity of the binder only from the application pressure of the Binder and the pulse duration of the spray pulses depends on the device to apply the binder in a simple manner using these parameters can be controlled precisely.
