Definitions

  • the invention relates to a self-propelled road milling machine for machining road surfaces according to the preamble of claim 1 and a method for machining road surfaces according to the preamble of claim 14.
  • Such road milling machines are already known in principle.
  • small milling machines where the milling drum is at the height of the rear axle of the chassis and between the rear wheels, it is known to provide on the null side of the machine, a rear jockey wheel or track drive, which can swing inward for edge-near milling behind the outer contour of the road milling machine.
  • Large milling machines are, for example, road milling machines in which the milling drum is mounted on the machine frame between the crawler tracks of the front and rear axles, and at a distance therefrom.
  • the EP 11 677 626 A1 describes such a large milling machine.
  • the milling rollers of such milling machines have a plurality of circumferentially preferably helically arranged tools.
  • these are milling tools which are fixed in tool holders welded onto a hollow cylindrical roller body or in chisel holder systems.
  • the tools therefore have a constant line spacing, which corresponds to the axial distance between adjacent tools and is usually between 3 mm and 25 mm.
  • line spacing depends on the respective milling task. Thus, in the development of complete lanes usually a larger line spacing is selected than in fine milling, which only serves the roughening of the road surface with low milling depth.
  • milling depth and desired surface structure also play a variety of other factors, such as the type of substrate to be processed for the choice of line spacing a role, which means that a variety of different milling drums with different line spacing for different tasks are available.
  • the invention is therefore an object of the invention to provide a road milling machine for processing road surfaces, as well as a method for editing road surfaces that allow flexible use for various milling tasks, expand the possibilities of milling, and can be used cost and time saving.
  • the invention advantageously provides that an oscillation drive exerts on the milling drum an oscillation stroke reciprocating in the axial direction relative to the machine frame, the rotational movement of the tools being superimposed by an axial movement parallel to the axis of the milling drum whose stroke is at the line spacing is adaptable between two axially adjacent tools.
  • the advantage of the invention is that with a single roughing or standard roll now large cutting depths can be achieved and at the same time fine surface structures are produced.
  • the line structure on the road surface can be changed or completely eliminated.
  • a road surface can be achieved with a structure that is not directly dependent on the line spacing of the milling drum. It also eliminates the need to use a milling drum, which produces a finer line structure on the milled surface.
  • Another advantage is that the changed surface structure of the road surface can be achieved even with larger cutting depths.
  • the tools perform a rotational movement about the Fräswalzenachse, which is superimposed by an axial movement parallel to the axis of the milling drum.
  • the stroke of the displacement of the milling drum in the axial direction can be adjusted according to the line spacing of two axially adjacent tools, so that the oscillation is variably variable on milling drums with different tool density. This eliminates changeover times and the provision of a variety of milling drums for different applications can be significantly reduced.
  • the invention makes it possible to save time and costs in an advantageous manner, because both coarse structures and fine structures can be produced with a single milling drum.
  • the fine groove structure produced during fine milling can negatively influence the steering behavior, in particular of two-wheeled vehicles, and lead to self-steering behavior.
  • This groove formation is reduced parallel to the traffic lane, even if the oscillation stroke is smaller than the line spacing.
  • the Oszillationshub does not have to correspond exactly to the line spacing, but also can be set lower or greater, or alternatively can be switched off completely, so that the road milling machine can be operated in a conventional manner.
  • the amplitude and / or the frequency of the oscillation are variably adjustable, so that the type of structure produced by the milling drum on the surface can be adapted individually to specific milling tasks.
  • the oscillation stroke in the range between 0.5 to 1.5 times, preferably between 0.9 to 1.1 times the line spacing can be adjusted.
  • the oscillation stroke can be adjustable in the range between 3 mm and 40 mm.
  • the frequency of the oscillation can be adjustable, for example, between 0.1 and 20 Hz.
  • the ratio of the average speed amount of the oscillation stroke to the peripheral speed of the milling drum tools lies in the range between 0.1 and 3, preferably between 0.25 and 2.
  • the milling drum has an axially movable axial bearing.
  • the movable axial bearing can be achieved in that the milling drum housing is displaced together with the milling drum or that the axial bearing is axially movable relative to the Fräswalzengephaseuses.
  • a reciprocating movement in the direction of travel can be superimposed on the axial bearing.
  • the milling drum can oscillate both in the axial direction and in the direction of travel.
  • a further oscillation drive is preferably provided.
  • the displacement of the milling drum in the direction of travel can be done not only linearly but also arcuately about an axis extending above the milling drum parallel to the milling drum axis.
  • a control is provided which automatically controls or regulates the oscillation frequency and / or the amplitude of the oscillation stroke as a function of the milling drum rotational speed and / or the feed rate and / or milling depth of the milling drum.
  • the milling drum oscillates together with the Fräswalzengephaseuse in the axial direction, and that the Oscillation drive the Fräswalzengephaseuse drives relative to the machine frame.
  • the oscillation drive drives the milling drum in the milling drum housing in the axial direction.
  • the milling drum housing is longer in the axial direction than the milling drum at least by the maximum oscillation stroke.
  • the axial bearing is a fixed-lot storage, in which the fixed bearing is displaceable in the axial direction.
  • the oscillation drive can act on the side of the fixed bearing axially on a running in the Fräswalzenachse drive shaft of the milling drum.
  • the movable bearing allows for a movement stroke that corresponds at least to the oscillation stroke.
  • the milling drum may have a rotary drive which drives a drive shaft on the side of the fixed bearing. If the entire Fräswalzengeophuse can oscillate in the axial direction, this is done along at least two linear guides, which extend parallel to the Fräswalzenachse in the axial direction.
  • the milling drum housing or the milling drum can be oscillated along at least two linear or arcuate guides in the direction of travel.
  • All guides have a first guide, which leads both vertically and horizontally, and at least one further, parallel to the first guide extending second guide, which leads at least in the horizontal direction.
  • the object is also achieved by the method according to claim 14, wherein during operation a reciprocating in the axial direction Oszillationshub is exerted on the milling drum in the axial direction, wherein the rotational movement of the tools is a parallel to the axis of the milling drum extending axial rotational motion is superimposed Hub is variably adjusted to the line spacing of two axially adjacent tools.
  • Fig. 1 shows a large milling machine as they basically from the EP 2 011 921 A is known.
  • the road milling machine 1 has a machine frame 8, which is supported by a chassis with at least three crawler tracks 20 or wheels.
  • the milling drum housing 10 is arranged in the direction of travel 22 between the crawler tracks 20, in small milling, however, rather at the level of the rear support wheels or crawler tracks 20th
  • the milling drum 12 is rotatable about a Fräswalzenachse 24 transverse to the direction 22, wherein the milling drum 12 is mounted in side walls 11, 13 of the Fräswalzengephaseuses 10 or on the machine frame 8.
  • the milling drum 12 may extend with its one end face to the outer side of the machine frame 8 designated as the zero side, whereas a drive device for the milling drum 12 may be arranged on the opposite outer wall of the machine frame 8.
  • the drive device for the milling drum 12 may be, for example, a mechanical drive having a belt drive 38 or a hydraulic or electric drive.
  • the driver's cab 14 Above the milling drum 12 is the driver's cab 14 with a seat for the driver.
  • Fig. 2a shows by way of example the arrangement of the tools 16 on the milling drum 12, as basically from the DE 102 03 732 is known.
  • the tools 16 In the circumferential direction, the tools 16 have a predetermined predominantly constant mutual distance.
  • a series of tools 16 may be provided which are not spirally arranged to produce vertical milling edges. Since the tools 16 do not change their axial position during the rotation of the milling drum 12, they produce on the road surface 2 grooves 18 which form in the direction of travel 22 on the road surface 2 in cross-section groove-shaped recesses, as for example in the FIGS. 2b and 2c are recognizable.
  • the distance 19 between two adjacent grooves 18 is therefore dependent on the line spacing of the milling drum, that is, the axial distance of the circumferentially adjacent tools 16.
  • line spacings are preferably common between 3 mm and 25 mm.
  • Fig. 2c schematically shows the distance 19 between the grooves 18, which results from the line spacing of the spirally arranged on the milling drum 12 tools 16.
  • two counter-rotating spirals of tools 16 are formed on the milling drum 12, which have the task to transport the milled material to the roll center or to a specific axial position of the milling drum 12.
  • Fig. 3 schematically shows a conventional axial bearing of a milling drum 12 in a Fräswalzengephaseuse 10, which is immovable axially relative to the machine frame 8.
  • the Fräswalzenachse 24 is mounted in the side walls 11, 13 of the Fräswalzengephaseuses 10, with the aid of a fixed bearing 30 and a floating bearing 32.
  • the floating bearing is axially movable to a small extent, so that, for example, thermal expansion of the Fräswalzenachse 24 can be compensated.
  • the milling drum drive is usually arranged, which can be done for example by a mechanical belt drive 38 but also hydraulically or electrically.
  • the inventively mounted in the end walls of the Fräswalzengephases 10 milling drum 12 has apart from a radial bearing axially movable axial bearing.
  • the fixed bearing (axial bearing) of the milling drum is moved relative to the machine frame 8, either with the entire Fräswalzengephaseuse 10 or relative to this.
  • Fig. 4 and 5 an embodiment is shown in which the axial movement of the milling drum is achieved in that the entire milling drum housing 10 with the milling drum 12 performs the Oszillationshub.
  • the oscillation drive 28 acts between the milling drum 12 and the milling drum housing 10.
  • the milling drum housing 10 is, as in FIGS. 4 and 5 can be seen along at least two linear mutually parallel guides 42a, 44a and 42b, 44b transversely to the direction of travel 22 movable to allow oscillation of the entire Fräswalzengepuruses 10 with the milling drum 12 in the axial direction parallel to the Fräswalzenachse 24 in a ground-parallel plane.
  • An oscillating drive 28, in particular a linear drive, e.g. from a piston-cylinder unit or a mechanical eccentric drive, or a spindle drive allows the oscillation of the milling drum housing 10 relative to the machine frame eighth
  • Fig. 5 is a schematic plan view of the an embodiment of FIG., From which it can be seen that the linear guides 42a, 42b parallel to the linear guides 44a and 44b and the Fräswalzenachse 24 extend.
  • each linear guide 42a, 42b and 44a, 44b may be made in one piece. This means that the guide elements 42a, 42b and 44a, 44b can be connected to one another or extend over the entire width of the milling drum housing 10.
  • Fig. 6 schematically shows a second embodiment in which the Fräswalzengepuruse 10 is rigidly fixed to the machine frame 8 and the milling drum 12 is mounted in the side walls 11, 13 via movable bearings 32a, 32b.
  • the oscillation drive 28 acts between the milling drum 12 and the milling drum housing 10.
  • the milling drum housing 10 is longer in the axial direction than the milling drum 12 by at least the maximum oscillation stroke.
  • Fig. 7 schematically shows the oscillating movement of the Fräswalzengepuruses 10 in the direction of travel 22, while Fig. 8 an embodiment in which the milling roller 12 can oscillate within the side walls 11, 13 in the direction of travel.
  • the Fräswalzenachse 24 is in the embodiment of Fig. 8 guided in the milling drum housing 10 in a horizontal slot 25.
  • the linear guides 42, 44, 46, 48 may for example also be provided in the manner of a cross slide.
  • the amplitude and / or the frequency of the oscillation in the axial direction and parallel to the direction of travel 22 are variably adjustable.
  • the oscillation stroke can be set in a range of 0.5 to 1.5 times the line spacing.
  • the maximum oscillation stroke is oriented at the line spacing and differs only slightly therefrom.
  • the oscillation stroke in a range between 3 mm, preferably 5 mm, and 40 mm adjustable.
  • the frequency of the oscillation can be set between 0.1 Hz and 40 Hz.
  • the frequency may be adjusted to achieve a certain ratio of the average axial velocity amount to the feed rate of the milling drum 12 or the peripheral speed of the tools of the milling drum 12 or the addition of the peripheral speed of the tools and the feed rate of the milling machine.
  • a relatively high milling roll speed in the range of 180 rpm to 600 rpm (or milling drum rotational frequency between 3 Hz to 10 Hz), preferably between 240 rpm to 360 rpm (or 4 Hz to 6 Hz) a relatively low oscillation frequency between 0.1 Hz to 5 Hz, more preferably between 1 Hz to 3 Hz, to be combined.
  • the oscillation frequencies refer to the specified range for the oscillation.
  • a low milling roll speed can be combined with a high oscillation speed.
  • the milling roll speed may range from 30 rpm to 180 rpm (corresponding to milling drum rotation frequency 0.5 Hz to 3 Hz), preferably between 60 rpm to 150 rpm (corresponding to 1 Hz to 2.5 Hz). at an oscillation frequency in the range between 2 Hz to 40 Hz, preferably between 5 Hz to 15 Hz.
  • this embodiment is preferable because it allows lower tool wear to be achieved (lower peripheral speed of the bits, i.e. lower forces on the tool being cut).
  • the oscillation frequency should not correspond to an integer multiple of the rotational frequency of the milling drum (or vice versa), since thus the cut could be made each time in the same, running in the direction of travel line. However, this effect is negligible in the case of fast oscillation, eg five times the rolling rotational frequency.
  • variable oscillation frequency is possible by superposition with a harmonic of the rotational frequency of the milling drum, e.g. with a bandwidth of 30% around the oscillation frequency.
  • the superimposed oscillating movement of the milling drum 12 parallel to the direction of travel 22 may also be linear instead of as in the FIGS. 7 and 8 illustrated, circular arc-shaped about a pivot axis 50 take place, which extends above and parallel to the Fräswalzenachse 24.
  • Fig. 9 shows an embodiment in which the milling drum housing 10 with the milling drum 12 about the pivot axis 50 in the direction of travel 22 can oscillate circular arc.
  • Fig. 10 shows an alternative embodiment in which the milling drum 12 can oscillate within the Fräswalzengephaseuses 10 about the pivot axis 50 in the direction of travel 22.
  • the slot 25 is curved in this case about the pivot axis 50 in the side walls 11 of the Fräswalzengephaseuses 10 arranged curved.
  • Fig. 11 shows a cross section through the longitudinal guides 42, 44, 46, 48, from which it can be seen that in each case one of the two mutually parallel guides 42, 48 has only one degree of freedom, namely in the axial direction and the respective other guide 44, 46 a degree of freedom in axial direction and a degree of freedom in the horizontal direction.
  • This design of the guides is suitable both for the linear guides 42, 44 acting in the axial direction and for the linear guides 46, 48 acting in the direction of travel.
  • the road milling machine may have a controller 14, the oscillation frequency and / or the amplitude of the oscillation depending on the Fräswalzennaviere and / or the feed rate of the milling machine and / or Cutting depth of the milling drum automatically controls or regulates.
  • parameters of the road surface for example, the consistency of the road surface can be taken into account.
