Definitions

  • the invention relates to a cutting body for generating a road marking with a rotating body rotatable about an axis of rotation, which can interchangeably accommodate a plurality of cutting elements which define a cutting curve.
  • a road milling machine with a cutting body which has a milling drum tube as a rotating body.
  • the roller surface is barrel-shaped and convex in the direction of the axis of rotation. It holds chisel holders in which chisels can be exchangeably held.
  • the chisels are equipped with carbide tips that serve as cutting elements.
  • the carbide tips form a convex cutting curve in the direction of the axis of rotation of the milling drum tube. This convex cutting curve results during the rotation of the rotating body.
  • a concave trough is produced transversely to the longitudinal extent of the roadway. Due to the circular cross-section of the rotating body, the depression has a concave shape even in the longitudinal direction.
  • a plurality of depressions are milled into the lane at an equal spacing from one another. The road marking thus forms a deliberate geometric unevenness in the road. When rolling over with a vehicle tire, noises and vibrations occur which are perceived by the driver and which signal him to leave the road, for example.
  • the road markings thus have the function and task of emitting an acoustic and haptic warning signal.
  • this noise source is sometimes perceived as disturbing by the surrounding area adjacent to the road.
  • Another disadvantage of the known road markings arises when driving over with a two-wheeler. The two-wheeler is moved laterally, which can then trigger dangerous steering corrections for the driver. If rainwater collects in the depressions, the driving situation of the two-wheeler can also become unstable.
  • a cutting body for producing a road marking is known.
  • a rotary body which has a large number of cutting elements.
  • the cutting elements are formed by diamond particles that are attached to a contoured surface of the rotating body.
  • the rotating body forms a cutting curve with the cutting elements.
  • the cutting curve is formed by four convex elevations and three concave transition sections.
  • the concave transition sections merge into these between the convex elevations.
  • This known cutting body can be set in rotation during the use of the tool and placed on the road surface to be machined.
  • the cutting bodies grind themselves into the road surface.
  • Line-shaped depressions can thus be introduced into the roadway. These line-shaped depressions serve to receive color, so that, for example, road side markings can be generated. Due to the grinding technology used, the indentations in the road surface can only be created with a low penetration depth.
  • Cutting bodies with which road markings can be milled into the road surface are also known from the prior art.
  • the US 2004/0005190 A1 shows such an arrangement.
  • Interchangeable cutting teeth are mounted on a cylindrical cutting roller.
  • the cutting teeth are positioned with respect to one another in a predetermined arrangement.
  • the cutting roller can be rotated.
  • the roller rotating device is assigned a lifting device which periodically raises and lowers the cutting roller.
  • the lifting and lowering movement is superimposed on a linear movement of the construction vehicle along the direction of the road. This creates a cutting movement, with each cutting tooth lifting a comma-shaped chip out of the road surface.
  • This essentially results in part-circular recesses in the road surface. Such recesses are unsuitable for use as vibrating strips.
  • Vibrating strips form deliberate geometric bumps in the road.
  • noises and vibrations occur which are perceived by the driver and which signal him to leave the road, for example.
  • the road markings according to the D2 result in sharp-edged transitions between the road surface and the road marking. These jagged transitions move a two-wheeler sideways when driving over it, which can then trigger dangerous steering corrections for the driver.
  • a relatively large amount of water collects in the depressions, which further unstabilizes the driving situation of the two-wheeler. It has also proven to be disadvantageous that there is a relatively high level of noise when driving over, which is sometimes perceived as annoying in the area adjacent to the road.
  • the cutting curve forms a concave cutting area in the direction of the axis of rotation, and that a concave cutting area connects to the convex cutting area on both sides.
  • depressions for road markings can be milled, in which the road surface is continuously transferred over the convex area into the concave floor.
  • the geometry of the lane markings also enables a two-wheeler to drive over it more easily and to reduce side distortion that unsettles the driver.
  • the volume formed by the depression is reduced with the convex region of the depression. This means that less water can collect in it, which significantly reduces the risk of instability of a two-wheeler on wet roads.
  • the rotary body has a fastening surface on which tool holders are fastened, which can receive the cutting elements interchangeably, that the fastening surface has a convex fastening section assigned to the convex cutting region and one has the concave cutting portion associated concave attachment portion.
  • the cutting curve can be generated in a simple manner using the same bit holder and cutting elements.
  • the concave cutting areas ends at the end facing away from the convex cutting area in an end area parallel to the axis of rotation. In this way, a harmonious transition to the road surface is created in the recess, which withstands particularly robust mechanical loads.
  • the radius of the convex cutting area is between 200 mm and 400 mm, and / or that the radius of the concave cutting area is between 400 mm and 800 mm, then corresponding geometries result at the depression, which have a reduced influence on the Sufficient noise can be generated by the tire guide.
  • a cutting body according to the invention can be characterized in that a fastening flange is arranged in the hollow area enclosed by the rotating body and that the fastening flange is coupled to the rotating body on the inner wall section assigned to the convex cutting area.
  • the fastening flange is thus fixed in the thickened section of the rotary body formed by the convex cutting area in a manner optimized for strength.
  • road markings can be produced in the form of depressions, the depressions having two lateral longitudinal walls running in the longitudinal direction of the road, which merge into a floor area, the depressions being delimited by two transverse walls running transverse to the direction of the road, with a convex area at least one of the longitudinal walls in a concave area of the floor is transferred and / or wherein the convex area of at least one of the side walls is transferred into the road surface.
  • depressions are created that have little impact on the lateral guidance of the wheel.
  • the transverse walls can have a concave region which is passed directly or indirectly into the road surface. Then a sufficiently high sound pressure is created when the wheel hits the transverse wall.
  • the depressions can be spaced apart from one another in the same division grid to form the road marking, or it is conceivable that the individual depressions directly adjoin one another.
  • Figure 1 shows a cutting body having a roller-shaped rotating body 10.
  • the rotary body 10 is tubular and has a cylindrical inner receptacle, which is formed by the jacket of the rotary body 10.
  • a fastening flange 11 with fastening receptacles 12 is arranged in the inner receptacle, to which the output shaft of a drive train can be flanged.
  • the jacket of the rotary body 10 forms a support part 13 with a barrel-shaped circumferential fastening surface 14.
  • the fastening surface 14 is composed of a central convex fastening section 14.2 and two concave fastening sections 14.1 adjoining it laterally.
  • the concave fastening sections 14.1 merge directly into the convex fastening section 14.2.
  • On the two mounting sections 14.1 and 14.2 are tool holder changing systems, consisting of a base part and a tool holder 20 which can be exchangeably fastened to it.
  • the base parts are welded to the fastening sections 14.1, 14.2.
  • the base parts are arranged offset to one another in the circumferential direction, so that there are clearing and loading turns that run spirally on the fastening sections 14.1, 14.2.
  • the chisel holders 20 are welded directly onto the fastening sections 14.1, 14.2, so that base parts can be dispensed with.
  • the chisel holders 20 have chisel holders in which chisels 21, preferably round-shank chisels, can be exchangeably received.
  • the chisels 21 are equipped with cutting elements which, when the rotary body 10 rotates about the axis of rotation R, define a cutting curve 15.
  • the cutting curve 15 forms a kind of envelope.
  • the cutting curve 15 forms a convex cutting area 15.2 and laterally adjoining concave cutting areas 15.1 corresponding to the configuration of the fastening sections 14.1, 14.2.
  • the radius R 1 of the concave cutting areas 15.1 is preferably between 400 mm and 800 mm.
  • the particularly preferred ratio R 1 : R 2 of approximately 2: 1 can be set.
  • the cutting body can be used to mill road markings, consisting of depressions 31 arranged in a row one behind the other, into the roadway 30.
  • the recess 31 has a concave bottom 31.2 complementary to the cutting curve 15 transversely to the longitudinal direction of the roadway, of which two convex longitudinal walls 31.1 rising up.
  • the longitudinal walls 31.1 merge into the road surface 32.
  • the transverse walls 31.3 running transversely to the longitudinal extent of the roadway are concavely curved in accordance with the circumference of the roller.
  • Figure 3 shows an embodiment variant in which the cutting body is fed perpendicular to the road surface 32 and after the cutting body has reached its deepest infeed position is reset again before it is offset by the desired division in the longitudinal direction of the road, etc.
  • Figure 4 shows one too Figure 3 changed procedure.
  • the cutting body is not reset above the level of the road surface 32, but is continuously advanced to the lowest infeed position during the feed movement along the longitudinal direction of the road and is returned to the level of the road surface, so that the depressions 31 are lined up directly.
  • the feed and reset movement can be coordinated with the feed movement in such a way that an alternating arrangement of convex and concave curved regions of the depression is likewise produced in the longitudinal direction of the carriageway. It can thereby be achieved that each individual depression of the series of depressions in the longitudinal section receives a curve shape similar to that of the cross section.
  • Figure 5a shows a cutting body 10 according to the prior art, which generates a cylindrical envelope with its chisels 21.
  • 10 road markings 31 with a partially cylindrical geometry can be milled with this cutting body, such as Figure 5b shows. That the Figure 5b removed enlarged detail acc.
  • Figure 5c shows that this road markings 31 rugged 90 ° transition between the road surface 32 and the subsequent longitudinal wall 31.1 results.
  • Figure 6a shows a further cutting body 10 according to the prior art (for example according to FIG US 6,547,484 B2 ).
  • the chisels 21 produce a spherical cutting curve.
  • This cutting body results in 10 road markings 31 of the in Figure 6b shown form.
  • Figure 6c shows one of the Figure 6b extracted detail. It can be seen here that the transition from the road surface 32 into the longitudinal side walls 31.1 compared to the variant of FIG Figures 5b and 5c is clearly flattened, but still forms a relatively steep transition.
