Definitions

  • the invention relates to a track-traveling machine for cleaning a track superstructure, in particular the ballast surface of a ballast bed located below a track grate formed from cross sleepers and rails, with a machine frame which can be moved on track bogies and a suction device which comprises a suction container with a collecting container
  • a filter and a fan-connected suction head arrangement which is assigned at least one pressure nozzle connected to a compressed air generator via a pressure channel to form an essentially closed pressure-suction system.
  • this suction device consists of a suction head arrangement connected via a suction channel to a collecting container with filter and a fan designed as a radial fan.
  • This suction head arrangement which is referred to as a pressure suction nozzle, is assigned a bell-shaped pressure nozzle which is connected to the radial blower via a pressure channel. Inside this is arranged the suction nozzle connected to the suction channel, through which the compressed air enriched with dirt is to be conveyed to the collecting container.
  • this track surface cleaning machine is relatively complex due to the two vehicles coupled to one another, the arrangement of the pressure nozzle in the outer region of the suction nozzle requiring a significantly higher suction effect of the suction nozzle in order to blow out the surface ballast or to raise dust to avoid the lateral openings formed between the pressure nozzle edge and the ballast surface.
  • the suction mouth opening is connected to height-adjustable end strips which are formed from a plurality of pairs of air guiding elements which are adjacent to one another in the cross-track direction and are height-adjustable independently of one another and are located on both sides of the suction mouth opening.
  • the suction device is connected to the collecting container via suction channels. Due to the special design with a plurality of height-adjustable end strips lying next to one another in the transverse direction, the air guiding elements are largely independent of one another, in particular for a method in track switch areas. This design is therefore structurally particularly complex and is subject to increased wear in the lower end region of the air guide element pairs. In addition, even with such a design, dirt stubbornly stuck to the ballast surface cannot be removed.
  • a track-drivable machine for extracting the entire ballast from ballast bedding is known, which is cleaned in a screening plant located on the machine and then thrown back onto the track.
  • a suction device which is arranged on the machine frame in a height-adjustable manner, is formed from three suction nozzles, each with its own flexible suction channel connected to the screening plant and a compressor, with suction mouth openings. These are assigned rotatable broaching tools for loosening or loosening the ballast in the track level.
  • the suction head arrangement which is shaped as a nozzle and can be adjusted longitudinally and transversely to the machine, is designed with a relatively small, round or rectangular cross-section in order to be able to absorb the heavy ballast - for the subsequent cleaning process.
  • This machine intended for picking up the ballast from smaller surface areas, in particular from difficult to access track areas - for a subsequent cleaning process - is therefore not suitable for efficient surface cleaning of ballast bedding.
  • a device which can be attached to a motor vehicle is only known for cleaning switches and rails.
  • a track wagon which can be raised and lowered and has two nozzle boxes each assigned to a rail track.
  • a suction, compressed air, pressurized water and lubricant nozzle is arranged in each of these. A surface cleaning of a ballast bed is not possible with this device.
  • the object of the invention is to provide a track-traveling machine of the type described in the introduction with which a more efficient and thorough suction of the dirt adhering to the surface, in particular of a ballast bed, can be achieved.
  • the object of the invention is now achieved with a machine described in the introduction in a surprisingly simple manner in that the pressure nozzle is arranged inside the suction mouth opening of the suction head arrangement and via the pressure channel with the exhaust air opening, which acts as a compressed air generator, and the suction head arrangement connected to the suction channel is connected to the suction opening of the radial fan connected to the suction head arrangement - to form the pressure-suction system.
  • the suction flow in a path which can be precisely defined by the inner arrangement of the pressure nozzle with respect to the outer suction mouth opening can be substantially increased, so that on the one hand the compressed air - and, on the other hand, exposed to the suction air flow and, for example, also adhered impurities on the ballast surface, loosened and whirled through and torn off completely.
  • the ballast surface therein is subjected to a particularly intensive pressure-suction air flow for detachment, also particularly sticky dirt or for suction also dirt lying between the ballast stones.
  • a particularly intensive pressure-suction air flow for detachment also particularly sticky dirt or for suction also dirt lying between the ballast stones.
  • the exhaust air of the radial fan can again be used as compressed air for the pressure nozzle in a closed ring system. In this way, especially in connection with a suction air flow prevailing in the edge region of the suction mouth opening, practically no pollution of the environment occurs at all.
  • the suction head arrangement consists of three transversely to the machine longitudinal direction arranged next to one another and which can be adjusted in height and possibly also transversely on a support frame by means of drives, and which are essentially designed with a rectangular suction mouth opening and each with an internally arranged pressure nozzle combined suction heads.
  • Such a design with three suction heads arranged side by side enables complete coverage of the entire track cross-section Except for the rails.
  • the suction heads can be placed in a particularly advantageous manner to increase the suction power with the edges on the sleepers or the adjacent rail foot, so that the intake of false air from openings between the ballast surface and the suction mouth opening is largely excluded.
  • Another useful development of the invention is that for the optional connection of the central suction head provided for arrangement between the rails or the two suction heads provided outside next to one or the other rail with the exhaust air opening and the suction opening of the Fan is arranged in each case a control device provided in the pressure and suction channel or in the end region thereof, which can be acted upon in particular by means of a remotely actuated drive and is preferably designed as a flap or slide.
  • a control device provided in the pressure and suction channel or in the end region thereof, which can be acted upon in particular by means of a remotely actuated drive and is preferably designed as a flap or slide.
  • the sleeper head area located next to a platform and therefore particularly dirty, while the exhaust air from the fan is passed on to the pressure nozzle, can be increasingly extracted, while the other two suction heads are used for suction without compressed air.
  • a suction head can be put out of operation if necessary.
  • the suction head arrangement preferably each suction head in the area above the suction mouth opening, has water nozzles which are connected via lines to a pump arranged on the machine frame and a water container, and preferably approximately pass horizontally through the suction head.
  • the arrangement of water nozzles in the area above the suction mouth opening allows water to be sprayed finely in the area of the formation of the suction air stream surrounding the pressure nozzle, and thus immediate moistening of the suctioned dust can be achieved, so that it adjoins the suction channel Collecting container fails due to gravity.
  • a further advantageous embodiment of the invention is that the suction mouth opening of the suction head arrangement or of the individual suction heads is connected to height-adjustable, in particular elastic end strips that extend to the surface of the track - except in the area of the two rails. With such end strips, in connection with placing the suction heads on two adjacent sleepers or the rail foot, a substantial seal between the track and the suction mouth opening can be achieved, as a result of which the suction power can be significantly increased.
  • the width of the suction head arrangement or of each suction head of the in particular rectangular shaped suction mouth opening is in accordance with another advantageous development of the invention in the machine longitudinal direction as an average threshold distance corresponding to or larger than the sleeper crib width, preferably about 6 0 cm is formed.
  • This configuration ensures that even at different threshold spacing, it is possible to place the side edges of the suction mouth openings running transversely to the machine longitudinal direction on two thresholds delimiting a threshold compartment. Covering the entire threshold compartment means that the ballast surface in this area is subjected to particularly intensive suction cleaning.
  • the pressure nozzle arranged within at least one suction head protrudes above the suction mouth opening as a blow pipe which is approximately circular or slit-shaped in cross section and has a lower, preferably conical, shape Blowing openings located end region is formed.
  • a particularly advantageous development of the invention provides that the blow pipe for height adjustment in relation to the suction head is connected to a height adjustment drive and a vibrator.
  • This height adjustability allows the blowing tube to be immersed selectively, for example, only for those track sections in which the ballast is particularly dirty.
  • it is also advantageous without having to lift the suction nozzle while reducing the suction effect, by repeatedly dipping into the ballast in order to be able to clean extremely dirty areas even better and with a greater depth effect.
  • a simplified penetration and an improved cleaning effect can also be achieved by the vibrator.
  • Another expedient embodiment of the invention consists in that the suction mouth opening of the suction head arrangement or the suction head is covered by a grid, the mesh size of which is smaller than the average ballast size of a ballast bed.
  • the invention further relates to an advantageous method for cleaning particularly heavily soiled ballast beds.
  • This method is characterized in that the suction heads provided with the pressure nozzles are lowered at a short distance to the sleeper surface and the machine travels continuously on the track in a first work approach, whereby the coarse, superficial dirt is removed by the compressed air extraction and whereupon the suction head arrangement with the suction heads under the side edges of the suction mouth openings is lowered to the upper edge of the threshold and the machine moves up in a second work approach cyclically from one to the next intermediate threshold compartment for stationary suction.
  • the sleeper compartments are subjected to a particularly intensive, second suction cleaning by placing the suction heads on the sleepers while placing the edges of the suction mouth.
