Definitions

  • the present invention relates to a method and a device for machining the treads of rails according to the preambles of claims 1 and 7.
  • DE-OS 28 01 110 and DE-OS 28 01 111 are rail grinding machines in which a plurality of sliding blocks arranged one behind the other in the longitudinal direction of the rail are moved back and forth during operation in an oscillating manner.
  • the slide stones are therefore continuously in contact with the surface of the rail during operation.
  • Continuous action of the slide stones on the rail surface is disadvantageous in that the pores between the abrasive particles are gradually blocked, which causes a significant deterioration in the abrasiveness.
  • the oscillating movement of the slide stones in accordance with the prior art loosens the grinding sludge formed on the work surfaces, this self-cleaning effect is limited. Due to the use of the oscillating sliding stones, a play-free drive mechanism of the rail vehicle is also necessary in order to produce a perfect grinding effect. This means that additional costs are required.
  • An object of the present invention is to provide a method and an apparatus for machining the running surfaces of rails, which (s) enable inexpensive but highly effective machining of rail running surfaces with the aid of simple means.
  • the invention ensures that the disadvantageously acting grinding sludge can be removed from the working surfaces of the grindstones during operation.
  • the grindstones are periodically brought into a cleaned state again and again during the operation of the device. This results in a significant increase in the grinding effect of the grindstones and thus a higher processing quality.
  • the method according to the invention therefore ensures a very high processing quality with a significantly longer service life of the grindstones compared to known methods. Otherwise, it is not necessary for the drive mechanism of the rail vehicle to be free of play got to. Expedient refinements of the method according to the invention result from subclaims 2-6.
  • the cleaning is expediently carried out by simply spraying in water.
  • the possibility of cleaning the working surfaces of whetstones in general and here in particular cleaning by simply spraying water also ensures that not only the working surfaces of the whetstones but also, secondarily, the rail running surface can be cleaned during operation of the device.
  • An increased grinding effect with simultaneous effective cleaning of the work surfaces is expediently achieved when the majority, in particular at least two, of the grinding stones are in the working position.
  • a simple activation or passivation of the device can be achieved in that all grindstones are lowered via a common support and in this position individual grindstones are lifted or lowered via separate drives. At the end of the machining process, the complete device can be brought into a passive position via the common carrier.
  • the grindstones can be moved vertically individually or in groups, in such a way that a periodic lifting and alternating between the grindstones (rest position) and lowering (working position) of the grindstones can be achieved and a cleaning device is provided which cleans the working surface of the grinding stone which is in the rest position.
  • the device according to the invention enables continuous cleaning of the individual grindstones during operation, thereby substantially increasing the grinding action of the grindstones and, as a result, increasing the processing quality of the rail surface.
  • Water nozzles located in the area of the respective grinding stone are expediently provided as the cleaning device.
  • the possibility of cleaning in general and here in particular cleaning by jetting water offers the additional advantage that, in addition to cleaning the working surfaces of the grindstones, the rail surface is also cleaned secondarily, so that the grindstones in the working position can process a freshly cleaned rail surface.
  • Each grindstone or grindstone unit is expediently assigned its own holding frame.
  • the vertical movement of the grindstone can therefore advantageously be controlled independently of the remaining grindstones. Leave in addition achieve further movement possibilities of the holding frame with a separate holding frame.
  • a hydraulic unit which is connected to the central frame or central support, is expediently used as the drive for the vertical movement of the grindstone, the holding frame serving as a counter bearing for the hydraulic unit.
  • This configuration is particularly easy to implement in terms of construction.
  • the holding frame and / or the hydraulic unit are connected to the central support via a transverse guide, the holding frame and / or the hydraulic unit of each grindstone can be moved vertically independently of the other grindstones.
  • the tracking of the position of a grindstone transverse to the longitudinal direction of the rail described in subclaim 11 can expediently be achieved in that by means of the transverse guide the drive causing the vertical movement, in particular the hydraulic unit, can be displaced transversely to the longitudinal axis of the rails, the holding frame both in the transverse direction and perpendicular to Rail is movably arranged on the hydraulic unit and the proximity switch are provided for detecting a displacement of the holding frame which is transverse to the rail.
  • This configuration has the advantage that deviations from the target position of the grinding tool due to the special arrangement of the holding frame are detectable and the transverse position can be adjusted via the transverse guide.
  • the holding frame is expediently U-shaped and has the tool holder on its open side.
  • the holding frame and tool holder then enclose the hydraulic unit, so to speak, thus forming a closed unit, but transverse mobility of the hydraulic unit remains possible.
  • a further embodiment is characterized in that at least one elastic member is provided between the holding frame and the hydraulic unit. This elastic member brings about an elastically loaded vertical mobility and transverse mobility of the holding frame.
  • a structurally particularly simple solution provides that at least one rubber buffer is used as the elastic member, which can be both compressed and has a transverse elasticity.
  • the device 1 shows, with reference number 1, the device according to the invention for machining the running surfaces of rails 3.
  • the device 1 comprises a chassis 2, which is itself driven or can be moved via a tractor (not shown).
  • a processing unit which has a central carrier 4 which is arranged so as to be vertically movable via hydraulic cylinders 6 and rockers 5.
  • the processing unit can consequently be lowered via the common carrier 4 into an active position that prevails during operation.
  • the entire machining unit is raised via the hydraulic cylinders 6.
  • the processing unit comprises a plurality of grinding stones 7 arranged one behind the other in the longitudinal direction of the rail 3 along the carrier 4 and which act on the surface of the rail during operation.
  • the underside of the respective grindstone 7 has a profile adapted to the surface contour of a rail.
  • the construction of the mounting or suspension of the individual grinding stones 7 can be seen from FIG.
  • the common carrier 4 stands with a hydraulic unit 11 via a transverse guide 10 in connection.
  • the hydraulic unit 11 comprises a pressure stamp 15 which is carried by a support part 16.
  • Support part 16 and pressure ram 15 form hydraulic unit 11.
  • the plunger 15 and the support part 16 are surrounded by a U-shaped holding frame 8, the open end of which is closed by a tool holder 9 to which the grindstone 7 is attached.
  • the U-shaped holding frame 8 and the tool holder 9 surround the hydraulic unit 11, the pressure ram 15 of the hydraulic unit 11 engaging on the inside of the narrow side of the U-shaped frame 8.
  • two rubber buffers 13 are inserted.
  • the plunger 15 of the hydraulic unit 11 When the plunger 15 of the hydraulic unit 11 is actuated, the two rubber buffers 13 permit vertical movement from the holding frame 8 to the hydraulic unit 11, the hydraulic unit 11 being supported on the tool holder 9 via the two rubber buffers 13.
  • this construction not only allows a vertical movement from the holding frame 8 to the hydraulic unit 11, but also a horizontal displacement of the two parts relative to one another.
  • the two rubber buffers 13 are deformed in the direction of the deflection.
  • the hydraulic unit 11 is arranged to be displaceable transversely to the longitudinal axis of the rail via the transverse guide 10 by means of a hydraulic cylinder 6. Furthermore, proximity switches 12 are provided on the holding frame 8 for determining changes in the distance from the hydraulic unit to the respective proximity switch 12. The proximity switches 12 are connected to a controller, which acts on a hydraulic valve 17.
  • Figures 2 and 3 denote the grindstone or its control in the working position, i. H. in direct contact with the running surface of the rail.
  • water nozzles 14 are provided in the area of the grindstone 7, which free the working surfaces of the grindstone 7 and secondarily also the rail surface from adhering grinding sludge during the period of rest of the respective grindstone 7.
  • the hydraulic valve 17 is actuated, whereby the hydraulic cylinder 6 performs a compensation movement of the hydraulic unit 11 via the transverse guide 10. This compensation movement is activated until the respective proximity switch 12 switches off when the desired position of the grindstone 7 is reached.
  • the method according to the invention and the related device enable a highly efficient machining of rail surfaces with a longer service life of the grindstones 7 compared to the prior art. Furthermore, an increased structural density of compared to the known devices mentioned at the outset Allows grinding stones. Ultimately, there are no special requirements for the drive mechanism of the towing vehicle. All in all, the invention proves to be an important advance in the field of surface processing of rails.
