Definitions

  • the invention relates to a milling cylinder for levelling verges along roads, comprising several ribs extending over the length of the milling cylinder and sweeping by rotation of the milling cylinder a cylindrical surface of revolution, wherein at least the side of each rib facing forwards in the direction of rotation extends substantially radially, viewed in a section perpendicular to the axis of rotation.
  • the invention further relates to an apparatus for levelling verges along roads, comprising a milling cylinder and a peg cylinder, which cylinders are both suspended at an inclination relative to horizontal corresponding to the intended inclination of the verge surface and such that the peg cylinder relative to the travelling direction of the apparatus is positioned behind the milling cylinder, as well as driving devices for rotating the two cylinders about their respective longitudinal axes.
  • gravel verges are normally provided, the surface of which, when the road has just been laid out, extends from the roadway substantially on a level therewith and somewhat out to the side, the verge having a certain slope to ensure that for instance rainwater running off the roadway is conducted further beyond the verge, until it seeps down into the ground or is conducted down into a ditch.
  • This drainage of water is important, as the water, if it seeps down into the ground immediately outside the roadway, on the long view may undermine the roadway.
  • Fig. 5 shows a drawing from an official, Danish instruction concerning re-profiling of verges.
  • Fig. 5 thus illustrates the purpose of re-profiling, namely that the material from a bank 18 is to be moved towards the roadway 2 to fill up a ditch 19.
  • the height of the bank and the depth of the ditch will typically be in the range of 0-15 cm.
  • the width b 1 will typically be in the area of 30-50 cm, and the width b 2 of the bank or the area, from which it is desired to remove the material to ensure a downward inclination, will typically be in the range of 75-100 cm.
  • the verge will, as mentioned, often be covered by grass. It is desirable when re-profiling that the cover of grass can be re-established without subsequent seeding. Therefore, a minimum damage of the existing roots of the verge is desired. After the re-profiling the verge has to be compacted, as a minimum by being run over by a vehicle used for the work (a lorry), to obtain the same carrying capacity as the adjacent areas.
  • DK-B-173221 describes a milling cylinder and an apparatus comprising the milling cylinder, which is suited for use in re-profiling of verges.
  • the milling cylinder comprises ribs extending from the lateral surface to a height of up to 30 mm from the lateral surface, and the ribs extend continuously over the whole length of the cylinder, along the generatrices of the lateral surface.
  • the milling cylinder and the peg cylinder are driven to rotation with a peripheral speed of 1-2 m/sec. and 1.6-3.2 m/sec., respectively. With this apparatus it is possible to work at a travelling speed of approximately 4-5 km/h.
  • the ribs only extend up to approximately 25 mm beyond the lateral surface of the cylinder in order not to become too power consuming.
  • the object of the invention is therefore to provide an improved apparatus for levelling or re-profiling verges.
  • each individual rib follows a helical line, which in the surface of revolution forms an angle in the range of approximately 10°-20°, with the generatrix direction of the surface of revolution. This corresponds to the fact that the helical line from one end to the other of the milling cylinder, relative to the generatrices, turns 1-2 times the peripheral distance between adjacent ribs.
  • the individual ribs in a preferred embodiment are divided into sections to facilitate the manufacture, then not more than 2 cm of spacing in axial direction (underlap) is present between two adjacent sections of a rib. If the spacing becomes too big, the desired degree of fineness of the treated verge surface will not be obtained.
  • the adjacent sections of a rib may be mutually overlapping in the axial direction, or the ends of adjacent sections of a rib may be substantially in line in the peripheral direction.
  • the individual sections extend preferably in the generatrix direction of the surface of revolution to make the manufacture as easy as possible.
  • the milling cylinder preferably comprises a substantially circular cylindrical body carrying the ribs, the body having a diameter of 20-50 cm, in particular approximately 30 cm, and the ribs have preferably a height of 25-50 mm, in particular 35-45 mm, and most particular approximately 40 mm.
  • a milling cylinder according to the invention it is possible in operation to travel at a speed of up to 15 km/h, dependent on the condition of the verge to be treated, without the power consumption becoming excessive.
  • DE-A-197 39 915 discloses an implement for digging off the top of a verge, said implement comprising a shovel bucket and a milling cylinder for digging off the top of the verge and throwing the dug off material into the shovel bucket.
  • the milling cylinder may comprise one of many known structures: ribs, knives, teeth, etc.
  • the milling cylinder is preferably floatingly suspended with the possibility of rotating about an axis extending in the intended travelling direction.
  • the floatingly suspended cylinder(s) is/are forced by a spring towards a basic position, in which the cylinder has the intended inclination.
  • the milling cylinder is preferably suspended such that the side facing forwards in operation is obliquely facing the roadway, the peg cylinder is suspended such that its side facing forwards in operation is obliquely facing away from the roadway, and the driving devices of the cylinders are adapted to drive the cylinders reversely relative to the travelling direction in operation.
  • the driving device of the milling cylinder is preferably adapted to give the milling cylinder a peripheral speed in the range of 1 to 4 m per sec.
  • the driving device of the peg cylinder may be adapted to give the peg cylinder a peripheral speed of 1 to 4 m per sec.
  • the apparatus also comprises a rotating brush.
  • the apparatus further comprises a support wheel connected with the end of the peg cylinder facing the roadway and running in parallel with the travelling direction.
  • the apparatus further comprises a screening device positioned on the side of the milling cylinder facing the roadway.
  • the apparatus is preferably carried by a motor vehicle, for instance a lorry.
  • the apparatus is preferably provided with a driving device yielding up to 90 kW, but very often the apparatus will only consume down to 15 kW. Of this amount approximately 1-2 kW is consumed by the rotating brush, approximately 20% or presumably 4-5 kW is consumed by the peg cylinder, whereas the major part is consumed by the milling cylinder.
  • the consumption of the milling cylinder is by far more dependent on the condition of the verge to be treated than is the consumption of the brush and the milling cylinder.
  • the line 1 symbolizes the border between a roadway 2 and a verge 3.
  • the apparatus comprises a milling cylinder 4 suspended in a frame 5 (see also Fig. 2 ).
  • a circular plate 7 is fastened by means of bolts 8, said plate being provided with two triangular flaps 9.
  • the flaps are provided with two coaxial holes 10 for being mounted at the end of a lift arm or the like.
  • a peg cylinder 11 is provided with a shaft 13 suspended in a frame 14 provided with a plate 6, which by means of bolts 8' is connected with a plate 7' provided with flaps 9' having coaxial holes 10' for suspension.
  • the two frames 5 and 14 each carry a motor, like for instance a hydraulic motor 15, 15', respectively, which through suitable gears 16 and 16', respectively, is adapted to run the milling cylinder 4 and the shaft 13 with the peg cylinder 11, respectively.
  • a motor like for instance a hydraulic motor 15, 15', respectively, which through suitable gears 16 and 16', respectively, is adapted to run the milling cylinder 4 and the shaft 13 with the peg cylinder 11, respectively.
  • the two frames 5 and 14 are for instance carried by a lorry, the frames being suspended by means of the holes 10, 10' in the flaps 9, 9', such that they may each rotate about a basic position, towards which they are stressed by means of springs (not shown), and about axes extending in parallel with a travelling direction 24 of the apparatus.
  • the angular position of the frames 5, 14' in horizontal plane can be adjusted, the plates 7, 7' being provided with a number of bolt holes (not shown).
  • the motor 15 of the milling cylinder 4 is positioned closest to the road, which enables the milling cylinder 4 to operate close to poles at the edges, crash barriers and the like objects at the roadside.
  • a rotating brush 12 with a substantially vertical axis of rotation is placed behind the cylinders relative to the travelling direction 24.
  • the rotational direction of the brush 12 is indicated by an arrow 12a.
  • a screen 21 is provided to prevent the milling cylinder 4 from throwing material on to the roadway 2.
  • a support wheel 22 is mounted on the frame 14.
  • the apparatus travels along a road in the direction shown by the arrow 24 with the milling cylinder in front to mill away a bank 18 and to move its material to a ditch 19 between the bank 18 and the roadway 2. In this manner material is moved from the hatched area of the bank 18 in Fig. 5 to the area of the ditch 19 likewise hatched.
  • the milling cylinder thereby divides the material milled away from the bank into fine particles, which is a prerequisite for its being re-used immediately after.
  • the succeeding peg cylinder 11 has the function of levelling the material from the previous bank and of removing roots, bigger stones and the like, which on account of the oblique position of the peg cylinder 11 is guided to the edge of the verge.
  • the brush 12 takes care of bringing material, which in spite of the screen 21 of the milling cylinder 4 may have been thrown on to the roadway 2, out into the verge 3 again.
  • the support wheel 22 runs in operation on the roadway 2 and ensures that the peg roller 11 does not hit the roadway.
  • the verge may be rolled, and the treatment is then finished.
  • the longitudinal direction of the milling cylinder 4 forms an angle relative to the transverse direction of the road of approximately 35°
  • the longitudinal axis of the peg roller 11 relative to the transverse direction of the road forms an angle of approximately 33°.
  • the two angles may according to conditions be adjusted up till 15° to one side or the other.
  • the milling cylinder 4 is according to the invention provided with ribs 25 extending along helical lines.
  • the ribs 25 are in the embodiment shown each divided into four sections, 25a, 25b, 25c, 25d, which are staggered relative to one another such that they, like steps, follow a helical line 30.
  • the sections are staggered in such a manner that the first section 25a of a rib is in line with the last section 25d' of the adjacent rib, the sections each extending along a generatrix of the lateral surface of the milling cylinder 4.
  • the helical line 30 in the plane of the lateral surface forms an angle ⁇ of approximately 15° with the generatrices.
  • ⁇ the angle
  • the milling cylinder 4 comprises in the embodiment a tubular piece 26, onto which carrier pieces 27 have been welded, on which carrier pieces the rib sections 25a-25d in the form of steel slats are fastened.
  • the ribs 25 protrude in the embodiment approximately 40 mm from the lateral surface of the tubular piece 26.
  • the milling cylinder has preferably a length of approximately 75 cm and an outer diameter (the diameter swept by the ribs 25) of approximately 38 cm, whereas the peg cylinder has a diameter of approximately 35 cm.
  • the peripheral speed of the milling cylinder as a consequence of its rotation is in the example of the embodiment between 1 and 4 m per sec.
  • the peripheral speed of the peg cylinder also lies between 1 and 4 m per sec.
  • the travelling speed of the apparatus in operation is 4-15 km/h depending on the condition of the verge 3.
  • the treated verge 3 has, where the bank 18 was previously situated, in spite of the use of a milling cylinder with ribs divided into sections a solid, untreated bottom, and the ditch 19 has been filled with the material from the bank and may subsequently be rolled over, for instance by means of the wheels of the lorry.
