Definitions

  • the invention relates to a milling device for removing applied on paved traffic surfaces order.
  • the invention further relates to a method for operating such a milling device.
  • For applied on paved traffic surfaces order is in particular applied road markings or applied tire abrasion of airplanes on a runway.
  • a variety of other applied on paved traffic surfaces order is conceivable, for example, in an accident on the traffic surface arrived cargo, which is an order, such as leaked paint.
  • Application that is applied to paved roads in connection with road markings consists in particular of adhesive tape, spray plastic, cold plastic, thermoplastic, paint or epoxy resin materials.
  • the exhaust hood ensures that the water does not escape and serves as a protective device against solid particles and road dirt, which are released by the demarcation, whirled up and then thrown through the air. Due to the sealing between the extraction hood and the roadway, the jet water accumulates with slurries and solids.
  • the driven spray bar rotates in the liquid bath, so that the high-pressure water jet does not strike the surface to be demarcated, but first has to penetrate the backwater. This significantly reduces the power of the water jet and thus the demarcation result.
  • the liquid in the suction hood and the solids can be sucked off only after a residence time, since a certain level must be reached within the hood.
  • the suction is done with vacuum, d. H. low air volume at high vacuum, about 60% vacuum.
  • vacuum d. H. low air volume at high vacuum, about 60% vacuum.
  • a milling device for removing applied on paved traffic surfaces job has a milling tool arranged within a hood-shaped housing, which is designed as a roller and, during operation, rotates about an axis arranged parallel to the traffic surface. Upon rotation of the milling tool, this thus acts directly on the traffic surface mechanically. This milling device thus operates according to another mode of action, without the use of high-pressure liquid.
  • the object of the present invention is to provide a milling device for removing applied on paved traffic surfaces order, with the above-discussed disadvantages are avoided and in particular a safe operation is ensured at high efficiency.
  • the object of the invention is also to provide an advantageous method for operating the milling device.
  • the object is achieved by a milling device according to the features of patent claim 1 and a method for operating the milling device according to the features of patent claim 15.
  • the milling device according to the invention serves to remove applied on paved traffic surfaces order. These are in particular applied road markings or applied tire abrasion of aircraft on a runway. In a working position, the milling device is movable relative to the traffic area.
  • the milling device according to the invention comprises an outer hood-shaped housing and an inner, hood-shaped housing, which is arranged inside the inner housing, and which can be rotated by means of a drive about a rotation axis spray bar with spray nozzles for passing fluid under high pressure, and one with the outer Housing connected suction, which is connectable to a suction on.
  • the two housings In the working position of the milling device, the two housings are open to the traffic area and it rotates the spray bar with the spray nozzles to an upright to the traffic surface axis.
  • the spray bar When milling out of the spray nozzles output liquid and milled order are sucked through a space formed between the housings and through the suction nozzle.
  • two hood-shaped housing are provided, wherein the outer hood-shaped housing has the function of a suction bell.
  • the outer hood-shaped housing has the function of a suction bell.
  • the liquid dispensed from the spray nozzles in particular water dispensed from the spray nozzles, and by means of the liquid removed from the traffic surface, are sucked in with the order Ambient air mixed and sucked this mixture through the suction nozzle from the milling device. Due to the suction through the gap, the milling device can generate a strong air velocity at low negative pressure, for example at 20% vacuum, and high air volume. The generated flow rate absorbs even the smallest liquid particles. Due to the described suction between the inner housing and the outer housing and the distance of the outer housing to the traffic surface accumulates within the outer housing no liquid.
  • the milling device has a chassis and rolling means mounted thereon, in particular wheels, wherein the rolling means contact the traffic area in the working position of the milling device.
  • rolling means By means of this rolling means it is ensured that the two housings maintain a constant distance to the traffic area in the working position of the milling device.
  • the rolling means can be designed differently, provided that the aforementioned purpose is met.
  • Rolling means can certainly be designed as circulating chains. When using wheels is especially provided that they are steerable.
  • auxiliary means for example a motor vehicle in which the milling device is mounted, to position the milling device in its working position at a small distance from the traffic surface, without thus bringing about contact of the milling device and the traffic surface via said rolling means.

  • the planar opening surface of the outer housing is arranged at a distance of 10 mm to 60 mm, preferably 20 mm to 30 mm, in particular 25 mm to the traffic area. It is thus a relatively small sized gap between the outer housing and traffic area, is sucked through the ambient air into the interior of the outer housing, specifically the space between the inner housing and the outer housing. This causes high flow velocities of the suction air in this area, whereby the liquid discharged from the spray nozzles and the remote application are optimally conveyed by means of the high-velocity air flow.
  • the flat opening surface of the inner housing is arranged at a greater distance from the traffic surface than the flat opening surface is particularly advantageous of the outer housing.
  • the flat opening surface of the outer housing is thus positioned closer to the traffic surface than the flat surface of the inner housing. Due to this greater distance between the inner housing and the traffic area, the liquid dispensed from the spray nozzles and also the remote application can be supplied in a streamlined manner to the air sucked through the outer housing.
  • this circumferential skirt is not required because milled material does not reach the area outside the outer housing due to the air flowing radially outward to radially inward, which flows in as ambient air below the outer housing. Such milled material is entrained inwardly by the suction air.
  • the apron is flexible. It preferably consists of flexible skirt segments.
  • the apron or the skirt segments are, in the working position of the milling device, arranged upright to the traffic area.
  • Schürz segments is therefore advantageous because the apron should seal to the traffic area and with slight unevenness in the traffic area the skirt segments these bumps under the aspect of sealing can better follow than a one-piece apron.
  • the opening for suction air between the skirt and the outer housing is preferably formed as a circumferential annular opening.
  • the intermediate space formed between the housings is formed as an annular space.
  • the intermediate space formed between the housings is subdivided into intermediate regions, such that liquid dispensed from the spray nozzles and milled application flows from the interstitial regions into the suction nozzle.
  • the milling device thus has gap areas for different guidance of suction air, liquid and milled order, so as to achieve optimum suction results.

  • the spraying bar is set in rotation via said components, liquid, specifically water, supplied to the spray nozzles and the suction device of the motor vehicle is actuated, so that suction air is sucked through the suction nozzle of the milling device.
  • the milling device assumes a position in a non-working position, in which it is folded substantially upwards, by means of which the motor vehicle can be driven in a conventional manner. If the milling device is pivoted downwards in its substantially horizontal position, it assumes the working position in which the motor vehicle and thus the milling device can be activated to remove the application applied to the traffic surface.
