Definitions

  • the present invention relates to a road construction machine, in particular a road finisher or a feeder vehicle for a road finisher, according to claim 1.
  • the invention also relates to a method for generating an air flow according to claim 15.
  • vapors and bituminous aerosols can arise in the immediate vicinity of the road finisher or feeder vehicle. They can be caused in particular when hot paving material is being transported or installed.
  • EP 0 843 044 A1 discloses a road finisher and a feeder with an extraction system which is designed to extract vapors and aerosols from an area above the auger positioned in front of the screed and to eject them above the driver's canopy of a driver's operating platform. Furthermore, the extraction system is designed to extract vapors from a bunker area for installation material and eject them above the roof structure. On the feeder vehicle, the extraction system can on the one hand extract vapors and aerosols that arise in the goods bunker area, as well as vapors and aerosols that arise along a conveyor device of the feeder, and eject them above the roof structure in order to reduce the concentration of vapors and aerosols in the area around the feeder vehicle.
  • DE 10 2012 007 869 A1 also discloses a road finisher with a suction device, by means of which vapors and aerosols can be sucked off along a longitudinal transport device for paving material, which runs below the driver's control station within the chassis, and can be introduced into an exhaust gas emission system, so that the vapors end up together with exhaust gases from above the driver's canopy exhaust pipe to be blown out into the environment.
  • JP 2014-139 388 A discloses a further suction system which is designed to suction from an area of the transverse distributor, which laterally distributes the paving material in front of the screed, and to eject it above a driver's operating area.
  • the above suction devices are designed to suck off vapors and/or aerosols at the point of origin and above on road finishers or feeder vehicles of a roof structure or above an operating platform set up for the driver.
  • the disadvantage of this is that experience has shown that the performance of these extraction systems is not entirely sufficient to prevent vapors and/or aerosols from penetrating the driver's operating area or other operating areas provided on the road finisher or feeder that are intended for an operator.
  • WO 2013/185867 A1 discloses a suction device, the suction opening of which is assigned to an area of the transverse distribution auger of a road finisher, with a blowing device for forming an air flushing horizontally covering the suction flow also being provided above the area of material distribution.
  • JP 2014-139 389 A discloses a road finisher with a blowing device positioned at the front of an engine compartment cover, which generates a forward-directed air flow above a material bunker in the direction of travel of the road finisher, with which the rising vapors and/or aerosols from the material bunker can be covered.
  • DE 10 2020 123 723 A1 discloses a road finisher which, viewed in the production direction, has at least one air nozzle unit in front of the screed for generating a vertical and/or horizontal air curtain, with the air curtain produced by means of the air nozzle unit delimiting the area between a first side plate and a second side plate of the screed, so that vapors from the Paving material from this area can be better sucked off by a suction device.
  • Such an air curtain has the same technical effect as a horizontal or vertical cover around the area of the auger.
  • DE 10 2020 123 723 A1 an air nozzle unit, which is arranged at a control station of the paver to create an air curtain around the control station so that vapors cannot reach the area of the control station.
  • the object of the invention is to provide a road construction machine, in particular a road finisher or a feeder vehicle for a road finisher, with which vapors and/or aerosols can be kept away from the operating personnel of the road construction machine even better. Furthermore, it is the object of the invention to provide a corresponding method.
  • the invention relates to a road construction machine which is designed in particular in the form of a road finisher or feeder vehicle for a road finisher.
  • the road construction machine according to the invention comprises at least one driver's control platform for a driver of the road construction machine and/or an external control station for an operator of the road construction machine.
  • the road construction machine according to the invention has at least one first air barrier device for the driver of the road construction machine and/or at least one second air barrier device for the operator of the external control panel of the road construction machine.
  • the road construction machine according to the invention comprises a material bunker arranged in front of the driver's operating platform in the direction of travel, with lateral material bunker halves for receiving a paving material.
  • the invention is characterized in that, viewed from above, the first air barrier device for generating at least one directed air flow in the form of an air wall extending within an area to the side of the driver's operating platform and/or that the second air barrier device for generating at least one air flow within an area to the side of the outside operator's platform present range extending, directed air flow is formed in the form of an air wall.
  • the areas mentioned above are located to the side of the actual geometry of the road construction machine when viewed from above and are often used by the driver and/or operator in practice to control and/or monitor the operation of the road construction machine from there.
  • the air wall formed within these outer regions in the invention provides an air barrier to isolate the driver and/or operator from vapors and/or aerosols. Furthermore, the air flow used to generate the air wall can provide a suction effect for transporting away air that may be contaminated with vapors and/or aerosols.
  • the driver's operating platform can have open outer sides when viewed in the direction of travel. Vapors and/or aerosols can conventionally be drawn into the area of the driver's operating platform through these open outer sides.
  • the air wall according to the invention can be designed in such a way next to the driver's operating platform, i.e. within a laterally adjacent zone of the driver's operating platform, that vapors and/or aerosols can be better kept away from the open outer sides.
  • the air wall generated outside of the driver's operating platform by means of the first air barrier device makes it possible, in particular, to seal off the area lying to the side of the driver's operating platform Area in front of the bunker, especially from the lateral halves of the bunker, rising vapors and/or aerosols.
  • this positive foreclosure effect for the driver of the road construction machine occurs when he is positioned to the side of the driver's control platform, for example when the driver's seat console he uses is swung out to the side, beyond the driver's control platform, which means that the driver himself is within this zone, i.e. to the side positioned on the driver's control platform.
  • the air wall created by the second air barrier device next to the outside control station offers an operator positioned to the side of the outside control station a comparable sealing effect against rising vapors and/or aerosols as the first air barrier device to the side of the driver's operating platform. Above all, vapors and/or aerosols from a transverse distribution channel can thus be better kept away from the operator.
  • an air wall formed in these zones is special for them effective for sealing off rising vapors and/or aerosols.
  • the air wall generated by means of the first and/or by means of the second air barrier device is preferably designed as an air wall that intersects the direction of travel of the road construction machine.
  • the air flow for generating the air wall can be blown out from the road construction machine transversely to the direction of travel or at a predetermined angle to the side. This achieves a double effect.
  • the air wall designed in this way as such can excellently shield a driver and/or operator positioned within the side zones, ie a driver and/or operator positioned next to the driver's control platform and/or next to the outside control station, from rising vapors and/or aerosols.
  • Such an air wall forms, so to speak, an air curtain for the driver and/or the operator of the road construction machine, which serves to at least reduce vapors and/or aerosols in the area in which it is located at the side.
  • the air flow that is expelled outwards from the road construction machine or tends to be angled forwards can transport aerosols and/or vapors sideways away from the driver and/or operator.
  • the air wall created is next to the Driver's control platform and/or next to the outside control station within adjoining zones at an angle of between 30° and 60° to the direction of travel.
  • the first air barrier device comprises at least one nozzle arranged on a roof segment that can be extended transversely to the direction of travel, at least one nozzle arranged on a driver's seat console that can be pivoted sideways to the driver's operating platform, at least one nozzle arranged on an A-pillar of a roof structure and/or at least one Nozzle arranged on the bunker halves to generate the air wall.
  • the area to the side of the driver's operating platform can be effectively sealed off from rising vapors and/or aerosols.
  • the nozzle of the first air barrier device is formed integrally on a component of the extendable roof segment.
  • the nozzle is arranged on a carrier of the extendable roof segment that faces the material bunker, for example in the form of a blowing strip, which extends essentially along the carrier.
  • the air wall that can be generated from top to bottom within the area on the side of the driver's operating platform by means of this blowing bar is essentially transverse to the direction of travel of the road construction machine and can protect a driver positioned behind, outside of the driver's operating platform or on the driver's operating platform from vapors rising from the bunker area and/or Shield aerosols.
  • the nozzle of the first air barrier device is preferably formed integrally on a substructure of the driver's seat console, for example on a floor panel, and/or integrally on a fall-out protection of the driver's seat console, for example within a railing section. This ensures that the air wall that can be generated by means of the nozzle is assigned directly to the driver's seat console and thus to the driver sitting on it for shielding from vapors and/or aerosols, especially when the driver's seat console is swung out laterally beyond the driver's operating platform.
  • the nozzle would be possible, for example, for the nozzle to run along an outer edge of the substructure at the front in the direction of travel or to be designed as part of an upper railing section of the fall-out protection, for example in the form of a cylindrical tube with a number of blow-out openings that serve to generate the directed air flow.
  • the nozzle of the first air barrier device is designed to be integrated within the A pillar, so that the A pillar forms a housing for the nozzle.
  • the A pillar is designed in the form of a hollow profile, with the nozzle extending in the form of a pipeline at least in sections within the A pillar.
  • nozzle blow-out openings be aligned with exhaust ports formed in the A-pillar to create the air wall of the invention to protect the driver from rising vapors and/or aerosols.
  • the first air barrier device preferably comprises a first nozzle fitted along the A pillar and a second nozzle fitted along a B pillar positioned behind the A pillar in the direction of travel, so that the two air walls generated by these nozzles at a distance from one another have a side of the driver's operating platform for train the driver positioned in this zone at least to the front and to the rear with limited air ducts.
  • the driver can be shielded from both vapors and/or aerosols from the material bunker area and from vapors and/or aerosols rising from a transverse distribution duct behind him in the direction of travel, especially when he is positioned on the driver's seat console to the side of the driver's operating platform.
  • An advantageous embodiment of the invention provides that the nozzle of the first air barrier device is formed within an upper edge of the half of the material bunker. In this way, vapors and/or aerosols escalating from an outer area of the halves of the material bunker can be shielded directly at the upper edge of the material bunker.
  • the nozzle preferably extends at least in sections along an upper edge of a rear wall of the half of the crop bunker and/or at least in sections along an upper edge of an outer wall of the half of the crop bunker in order to advantageously intercept, dilute and remove the vapors and/or aerosols rising from the outer area of the crop bunker to transport.
  • the air wall thus generated functionally forms an extension on the rear wall of the bunker and/or on the outer wall of the bunker and can form an air drop side that extends beyond the bunker wall made of metal. In this way, vapors and/or aerosols from the material bunker can both be shielded better and transported away better above a height level of the driver and other operators working in the area of the road construction machine.
  • the first air barrier device or at least one fan device that is provided on the road construction machine and supports the first air barrier device is designed to generate at least one directed air flow in the direction of travel that is assigned at least in sections along a front area of the driver's operating platform in the form of an air wall.
  • This air wall can extend in the direction of travel directly in front of the driver's operating platform and in particular protrude as an air barrier from the driver's operating platform.
  • the air flow formed along the front area of the driver's operating platform preferably has the same flow direction as the air flow generated by means of the first air barrier device for generating the air flow within the area present at the side of the driver's operating platform.
  • the two air flows can be controlled in such a way that they merge into one another across areas, resulting in an enlarged, closed air barrier for the driver of the road construction machine.
  • the airflow formed in front of the driver's operating platform could be directed transversely to the direction of travel in order to entrain air that may be contaminated with aerosols and/or vapors sideways from the front area of the driver's operating platform.
  • polluted air can be pushed sideways out of the driver's area.
  • This further improves the air quality in the area of the driver's operating platform.
  • a nozzle could be used, for example, which is attached at least in sections along the A-pillar and is preferably integrated therein. The air flow generated by means of this nozzle can extend transversely from the A pillar having the nozzle in the form of an air wall to a further A pillar arranged offset to the side.
  • the air wall generated in front of the driver's operating platform could be formed by an upwardly directed airflow flowing out of an engine cover part adjacent to the front area of the driver's operating platform.
  • an air flow which is preferably directed vertically upwards, can entrain polluted air upwards, i.e. transport it away to an area above the operator.
  • the air flow formed in front of the driver's operating platform is in the form of an air wall formed directly behind a windshield in the direction of travel.
  • the windscreen can thus be defogged and, on the other hand, it can also serve as a guide geometry for the air flow.
  • an air wall running essentially parallel to the windscreen and formed directly behind it has the advantage that the driver on the driver's operating platform is not blown on as a result.
  • the second air barrier device preferably has at least one nozzle arranged on a side slide of the outside control station for generating the air wall and/or at least one nozzle arranged on a roof of the outside control station for generating the air wall.
  • the nozzle could be in the form of a substantially vertical blowing bar, offset laterally in the direction of travel relative to the outside control station to create an air wall in the adjacent area to shield vapors and/or aerosols.
  • the nozzle located on the canopy of the outside control station is positioned along a cross-directional front beam of the canopy to form a top-down curtain of air to the side of the outside station immediately in front of an operator positioned below.
  • the second air barrier device has at least one nozzle arranged on a rear wall of the screed for generating an upward air flow and/or at least one nozzle arranged below a screed walkway for generating an air flow directed counter to the direction of travel of the road construction machine.
  • Such nozzles can effectively supplement the air wall generated by the second air barrier device on the side of the outside control station in order to additionally protect the operator of the outside control station from rising vapors and/or aerosols, even if he changes sides of the screed via the catwalk attached to the rear wall of the screed.
  • a nozzle arranged below the screed walkway would have the advantage that the air wall thus generated could spread out like a carpet above a newly laid paving course, which means that vapors and/or aerosols can be retained on the surface of the newly laid paving course.
  • the nozzle arranged along the rear wall of the screed and/or the nozzle arranged below the screed catwalk can generate an air flow that can be dynamically adjusted depending on a distance measurement to a following compactor vehicle, for example to a roller.
  • the air flow produced by means of these nozzles could be automatically increased in order to better protect the driver of the following compactor vehicle from rising aerosols and/or vapors.
  • the first and/or the second air barrier device can be operated using a fan configured in the engine compartment of the road construction machine to generate a flow of cooling air and/or comprises at least one filter unit for cleaning the air conveyed therein.
  • a fan thus fulfills a dual function in that it can be used on the one hand to drive the cooling air flow to dissipate heat in the area of the motor and on the other hand as a drive for the first and/or second air barrier device.
  • a volume flow generated by means of the first and/or the second air barrier device can be varied dynamically as a function of a set and/or recorded process parameter of the road construction machine.
  • the first and/or the second air barrier device may therefore be connected to a controller configured to dynamically control the fan speed of a separate fan drive or the aforesaid fan based on a temperature of the mounting material.
  • this can be designed in the form of a rail or a blowing strip which has a plurality of blowing-out openings.
  • a wall of air created in this way can thus be designed directly as a transparent border of the outer work areas available to the driver and/or the operator of the outside control station.
