Definitions

  • the invention relates to a machine for cleaning dirty ballast of a track, comprising a screening system which has at least one outlet opening for cleaned ballast with a guide device adjustable by a drive, the screening system being assigned transport devices for transporting cleaned ballast and overburden.
  • the invention also relates to a method which is carried out by means of the machine.
  • ballast bedding of a track becomes soiled during the idle time due to environmental influences and due to the driving operation and must therefore be cleaned at regular intervals.
  • ballast is excavated by a clearing device and fed to a screening system of the cleaning machine. There, the excavated material is separated into reusable ballast and waste, which is designated as overburden and no longer needs to be used for a new ballast bedding. The ballast is thrown off with suitable transport devices to form a new bedding, while the overburden is separated and fed to storage and disposal with further transport devices.
  • EP 2 852 706 A1 it is also known to reintroduce the overburden as a formation protection layer below the ballast bed.
  • GB 2 023 206 A shows a cleaning machine with a storage container for cleaned ballast. This can result in a deficiency or an excess of Ballast can be reliably compensated for during the ballasting of the track.
  • the invention is based on the object of developing a machine and a method with which the cleaning can be carried out under special conditions, in particular when the track is lowered.
  • the cleaned ballast can be partially fed to the transport device for the overburden by means of the guide device.
  • a machine in which ballast that has already been cleaned in part, is removed again and is not used to build a new track bed, is used under certain conditions or certain specifications from railway administrations. It is possible that a track that has already been tamped up through several tamping processes is too high. In the course of a necessary cleaning, the track is lowered and the resulting excess ballast is compensated for by removing the ballast.
  • the track is optimally prepared for the subsequent processing by removing ballast beforehand.
  • This training also ensures a particularly simple routing of the excess ballast using existing transport facilities.
  • a particularly simple design of the guide device provides that it can be pivoted about an axis. The amount of diverted purified Gravel is then determined by the position into which the guide device is pivoted.
  • the outlet opening is assigned a chute which forms a gravel channel delimited by side walls and a floor, the guide device forming part of a side wall.
  • a chute is particularly suitable for retrofitting in existing cleaning machines, which increases their possible uses.
  • An extension provides that the screening system has two outlet openings with two guide devices, which are spaced apart from one another in a cross-machine direction. This embodiment achieves a high volume or mass throughput and a particularly favorable distribution of the cleaned ballast.
  • the transport device for the cleaned ballast is assigned a measuring device for measuring the volume or mass flow, which is connected to a control device and the drive of the guide device.
  • a wedge-shaped design of the guide device wherein a cross section of the guide device tapers towards an end of the guide device opposite the vertical axis, enables a favorable ballast flow and high stability of the guide device.
  • the drive is designed as a hydraulic piston / cylinder unit arranged below the floor, which is connected to the guide device by a lever. This ensures a protected drive and increases operational safety.
  • the cleaned ballast is partially introduced into the track.
  • This provides a simple method for cleaning processes with excess ballast.
  • the cleaned ballast is partly returned to the overburden.
  • the Superfluous ballast can be transported away in a logistically simple manner with existing transport capacities.
  • a previous removal of soiled ballast ie direct removal of ballast and overburden while bypassing the sieve, has proven to be technically very difficult to achieve and to be almost impossible to control. This is mainly due to the fact that the dirt on the ballast varies constantly. Controlling the flow of material is therefore very difficult.
  • the required amount of cleaned ballast can be provided very well.
  • a volume or mass flow of the cleaned ballast is measured, the guiding device for the cleaned ballast being actuated as a function of this. This means that the amount of cleaned ballast can be continuously recorded and precisely the required amount of cleaned ballast can be brought in or transported away.
  • a section of a machine 1 for cleaning dirty ballast 2 of a track 3 is shown.
  • the machine 1 consists essentially of a movable machine frame 5 supported on rail bogies 4 on track 3 and a ballast clearing device 6 and transport devices 7 for receiving it and arranged for transporting the soiled ballast 2 and a screening system 9 consisting of two screening units 8.
  • the screening plant 9 is assigned further transport devices 10, 11 for transporting cleaned gravel 12 and screened overburden 13 ( Fig. 2 ).
  • the cleaned ballast 12 is transported against a working direction 14 of the machine 1 and dropped back onto the track 3 at a dropping point 15 behind the ballast clearing device 6.
  • the ballast clearing device 6 is arranged in its own machine.
  • the machine 1 according to the invention then only comprises the screening system 9 and various transport devices 10, 11.
  • the screening system 9 or each screening unit 8 has at least one outlet opening 16.
  • the embodiment shown includes two outlet openings 16, spaced from one another in a machine transverse direction 17, for each sieve unit 8.
  • a transport device 10 and a guide device 18 are assigned to each outlet opening 16. This enables the cleaned ballast 12 to be fed to the transport device 11, which mainly serves to transport the overburden 13 away.
  • FIG Fig. 3 The structure of the guide device 18 is shown in FIG Fig. 3 shown in more detail.
  • a chute 19 is assigned to each outlet opening 16. This forms a ballast channel 22 delimited by side walls 20 and a floor 21, which serves to convey the cleaned ballast 12 to the transport devices 10, 11.
  • the guide device 18 forms part of a side wall 20.
  • the guide device 18 is connected to a drive 23 which enables the guide device 18 to pivot about an approximately vertical axis 24.
  • the transport device 10 is assigned a measuring device 25, designed for example as a scanner, for measuring the volume or mass flow.
  • the measuring device 25 is connected to a control device 26 and the drive 23 of the guide device 18.
  • ballast clearance the cleaning of soiled ballast 2 of the track 3 and the separation of ballast 2 and overburden 13 in the screening plant 9 are not discussed in more detail.
  • the cleaned ballast 12 is reintroduced into the track 3 in accordance with the known prior art. In this case, however, not all of the cleaned ballast 12 is brought in, but rather this is partially separated. This is expediently done by partially feeding the ballast 12 to the overburden 13. If the volume flow of the cleaned ballast 12 is measured, the guide device 18 can be actuated as a function of the measurement and the amount of ballast brought back into the track 3 can be precisely regulated.
  • Fig. 2 the guide devices 18 are shown in a position in which the cleaned ballast 12 is brought in its entirety onto the transport devices 10 for cleaned ballast 12 and subsequently into the track 3.
  • Fig. 3 the guide device 18 has been pivoted by actuating the drive 23. This creates, on the one hand, an opening 31 in the side wall 20 and, on the other hand, the gravel flow, which is indicated by arrows 27, divides. Thus, part of the cleaned ballast 12 passes through the opening 31 onto the transport device 11 for the overburden 13 and is transported away together with the overburden 13.
  • a further embodiment of the guide device 18 is shown. This is wedge-shaped, with a cross section of the guide device 18 tapers to an end 28 of the guide device 18 opposite the axis 24.
  • the drive 23 is designed as a hydraulic piston / cylinder unit 29 and is arranged below the base 21. In order to achieve an advantageous articulation and pivoting about the vertical axis 24, the drive is connected to the guide device 18 by a lever 30.
  • the guide device 18 is in Fig. 4 shown in a pivoted position, the divided gravel flow is again illustrated by arrows 27. A position in which the guide device 18 closes the opening 31 is shown in phantom.
