Definitions

  • the invention relates to a method according to the preamble of patent claim 1 and to a chassis which uses this method.
  • the known rail processing machines suffered from the disadvantage that they only name the deformed condition of the rail as the starting point for further machining of the rail, without taking into account the track gauge changed by abrasion, which is associated with serious disadvantages.
  • the grinding operations on the rail head were therefore more or less randomly dependent on the current track width of the worn rail profiles of the double strand.
  • the invention is therefore based on the object of providing a method for machining rails and an associated undercarriage which enables high-precision machining of the rail head.
  • the method is characterized by the technical teaching of claim 1.
  • Reference plane is a horizontal plane that is defined at a certain vertical distance below the tread of the rail head. The vertical distance from the tread is 14 mm, for example. The reference plane defined in this way can therefore lie in the region of the deformed or undeformed running edge depending on the height of the rail head.
  • the deformed track profile (this is the changed track width) by taking a measurement between the opposing, deformed running edges at the level of the reference plane.
  • the rail head is traversed only in a certain area, the removal taking place in the area of the lateral running edges in the upper half of this rail head.
  • Such non-contact measuring devices are e.g. Laser measuring devices, infrared measuring devices or the like.
  • the inventive idea of the present invention thus covers both measuring devices that touch the driving edges and non-contact measuring devices.
  • a chassis which essentially consists of a guide chassis and a roller side.
  • the guide carriage of this carriage consists of two mutually spaced subframes that roll on one rail side, while these subframes of the guide carriage are assigned the roller assemblies that roll on the opposite rail.
  • Each subframe of the guide undercarriage is therefore assigned a roller arrangement on the opposite side (roller side) of the undercarriage.
  • the above-mentioned subframes on one side and the roller arrangement on the other side are connected to one another by a chassis, which in a preferred embodiment is designed as a pull-out chassis in order to adapt the entire chassis to different track gauges.
  • gauges of 1,435 mm are used for state railways, for example, and the pull-out undercarriage is then rigidly set to this gauge.
  • other track gauges are used and accordingly the track width of the pull-out undercarriage is on it set.
  • lateral guide rollers are present on the subframe side of the undercarriage, which rest at the level of the reference plane of the deformed traveling edges and thus ensure a precisely defined position of the undercarriage on this rail profile.
  • the track width of the undercarriage is now set with high precision by the track widths of the track rollers arranged there being adjustable and lockable.
  • this actual width is now adjusted to the track width of the rollers on the roller side of the undercarriage, so that the undercarriage now has an overall track width that corresponds exactly to the deformed actual width.
  • the rollers on the roller side can be adjusted using various adjustment mechanisms. All adjustment devices are encompassed by the inventive concept of the present invention.
  • the roller side of the undercarriage is formed in each case from one or more rollers arranged at a distance from one another, wherein in the presence of more than two rollers these rollers are connected to one another by a common bar on which these rollers are rotatable are stored.
  • the free, pivotable end of a track control lever which is designed to be pivotable via a track adjustment cylinder, engages on the beam.
  • the first preferred embodiment is therefore an oscillating suspension of preferably pairs of rollers, which are arranged on a beam connecting the rollers, the beam - as shown - oscillating on lower free end of the track control lever is arranged.
  • rollers or pairs of rollers are slidably held in the manner of a longitudinal guide in the chassis, and this longitudinal guide is designed to be displaceable by corresponding linear drive units.
  • the one or more rollers are then mounted in a carriage which is slidably received in the chassis of the chassis.
  • the undercarriage forms a stable three-point support in that the track roller arrangements are held on the undercarriage in a height-adjustable manner.
  • This height adjustment ensures that a three-point support is achieved because the subframes are rigidly connected to one another on one side of the rail, while the roller assemblies on the opposite side of the rail are designed to be height-adjustable in order to ensure that only three "points" are loaded on each of the two rails .
  • This ensures that a resultant force is generated in the middle of the chassis between the two roller assemblies, which ensures the aforementioned stable three-point support.
  • a virtual support point on the rail is thus created in the area between the two caster arrangements, which take a mutual distance from one another, and this virtual support point is opposed by the two stable, fixed support points opposite each other in the area of the subframe.
  • the track width sensors are then in contact with the deformed running edges on the subframe side at the level of the reference level and also on the deformed driving edges at the level of the reference level and measure the actual state of the track profile in the deformed state.
  • Another essential feature of the invention is that, according to the invention, with the method and the chassis which have been described above, it is now possible for the first time to machine rail areas in the area of simple crossings and points as well as in the area of double crossing points. (This was not possible before, because all previously known undercarriages only recorded the deformed actual condition of the roadway edges and therefore attached a new rail profile more or less undefined).
  • a rail head 26 subject to wear is first machined on its running surface 27 and a corrugated surface 28 results in the region of the running surface 27. If the rail head 26 is used as an outer rail, then the left-hand running edge 33 is deformed, as shown in FIG. 1, causing deformation a removal profile 30 results, which is shown with dash-dotted lines. This means that the entire profile in the area of line 39 is traversed and a concave removal profile 30 results.
  • the deformed actual width between mutually opposite rail heads 26 is measured in that in the area of the undeformed running edge 33, namely at the level of the reference plane 34, a contact or non-contact measurement is carried out between the mutually opposite running edges 33. This ensures that the deformed driving edge is measured at the level of the reference plane and the distance between deformed driving edges at the level of the reference level is set as a measure for the setting of the wheel of the chassis on the roller side.
  • the undercarriage according to the invention essentially consists of a main frame 1, which consists of a longitudinal beam 40 to which the crossbeams are fastened parallel to one another at a mutual distance.
  • These cross bars 41 form between them a receptacle for a pull-out trolley 3, which essentially consists of a slide which is designed to be displaceable in the transverse direction with corresponding guide rollers in the profile between the cross bars 41.
  • a lifting cylinder 6 is arranged in the pull-out undercarriage 3 and is directed downward in the direction of the track bed.
  • the entire undercarriage By acting on the lifting cylinder 6, the entire undercarriage can thus be lifted out of the rail bed; it is then rotated around the lifting cylinder 6 and inserted back into the rail bed in the rotated position.
  • the longitudinal beam 40 is connected on both sides to an upper and a lower pivot bearing 4, these pivot bearings 4 being part of a main bogie 2.
  • This main bogie 2 is formed from two subframes 35, 36 which are at a mutual distance from one another, the upper pivot bearing being designated 4a and the lower pivot bearing 4b.
  • a telescopic tube is held, which is part of the main bogie and in which an extension trolley 3 is telescopically guided.
  • brackets 42 are firmly welded to the larger tube of the main bogie 2 and carry on their underside main support rollers 8 which, according to FIGS. 5 and 6, roll on the running surface 27 of the rail head 26.
  • These main support rollers 8 thus have essentially horizontal axes of rotation.
  • lateral guide rollers 7 Perpendicular to these main support rollers 8 are lateral guide rollers 7 with vertical axes of rotation on the underside of the main bogie 2, the guide rollers 7 in a bearing 7a on the Bottom of the main bogie 2 are held. It is important that these guide rollers 7 have a trapezoidal profile on the outer circumference, which is relatively narrow, so that only the deformed driving edges 33 are touched at the level of the reference plane 34. A precisely defined, lateral contact of the entire main bogie 2 on the subframe side 35, 36 for this chassis is thus achieved.
  • track sensors 12b act on the same running edge 33 at the level of the reference plane 34 and are pressed by spring force against the deformed driving edge 33 at the level of the reference plane 34 of the rail head 26.
  • the precisely defined contact of the guide rollers 7 on the deformed driving edges 33 at the level of the reference plane 34 thus ensures a precisely defined contact of the track sensors 12b on this surface.
  • the two subframe arrangements 35, 36 are formed exactly on one side of the undercarriage, so that it is sufficient to describe only one subframe.
  • the opposite side of the subframe is also symmetrical and consists of two identically constructed roller assemblies 37, 38, with each roller assembly 37, 38 being assigned two rollers 9 in the exemplary embodiment shown.
  • two rollers are through a roller lever 13 connected to each other and rotatably supported on this roller lever.
  • a pivot bearing 43 for attacking a lifting device, which essentially consists of a pivot frame 44, which consists of triangular converging beams, which are combined in the lower pivot bearing 43.
  • the upper part of the swivel frame 44 is held in a swivel bearing 45 on which one end of a rocker arm 46 engages, the other end of which is held in a rocker bearing 47 fixed to the chassis.
  • a first bearing eye 48 is provided for engaging one end of a height compensation cylinder 17, which engages with the other end in the region of the pivot bearing 45 on the pivot frame 44.
  • rollers 9 are rotatably mounted on the roller lever 13.
  • a steering pin 49 is fixedly connected to the roller lever 13 and engages in a slot-shaped recess 50 of a fork 51 which is pivotally received in a pivot bearing 52.
  • the steering pin 49 is fixed in the region of a handlebar 14 arranged, which in turn is firmly connected to the roller lever 13.
  • This pivot bearing 52 is fixed to the chassis on the side of the chassis.
  • the fork 51 is connected in a rotationally fixed manner to a track control lever 14, on the free, pivotable end of which one side of a track adjustment cylinder 16 engages, the other side of which is received in a bearing eye 53 fixed to the chassis.
  • the impeller 9 is thus pivoted in the arrow directions 54 to the rail head of the rail 18, so that the actual width between the two opposite rails 18 in the region of the deformed running edge 33 is set precisely at the level of the reference plane 34.
  • track sensors 12 are also pressed onto this rail 18 (left side in FIG. 6) under spring force in order to carry out the desired measurement.
  • the track sensors 12 are in turn - as described above - pivotally held on the underside of the chassis and are pressed under spring force against the driving edge 33 at the level of the reference plane of the rail 18.
  • the measured dimension is entered into a controller and this controller controls the tracking cylinder 16 so that the rollers 9 of the roller assembly 37, 38 of the main frame 1 are set exactly to this dimension.
  • wheel links 19, 20 are anchored in the rail bed in a known manner. It is therefore not possible to measure the distance between the track sensors 12.
  • Wheel control sensors 10 are provided (see FIGS. 2 and 3), which, according to FIG. 7, rest on the respective inner sides of the wheel control arms 19, 20. If such a presence of a wheel control arm is detected by the wheel control arm sensors 10a, 10b, then the previously made settings of the track width and the height of the roller arrangement are frozen and locked.
  • the rail processing machines are arranged in different locations on the running gear. It was mentioned only by way of example beforehand that the corresponding driver's cab and the supply units are arranged on the unit frame 5.
  • the grinding machines 21 for processing the driving edges 33 are fastened to the front of the main bogie 2 and the corresponding grinding wheel processes the vertical driving edges 33.
  • a further grinding machine arrangement 22 is preferably arranged in the center area on the longitudinal beam 40 for de-stripping the corrugated surface 28, while in the rear area of the undercarriage a processing machine, e.g. a grinding machine 23 is provided for profile regeneration of the driving edges and the treads. All grinding machines 21-23 are equipped with corresponding grinding wheels 24, only a few of which are shown as examples.
  • grinding wheel should also not be understood as limiting. Any machining tools that do not necessarily have the shape of a grinding wheel can be present. Likewise, different milling cutters can be used, and instead of the grinding machines 21-33 shown here, other tools for rail machining can also be carried, such as welding machines or measuring devices, which only the actual state of the deformed and / or undeformed track profile without having to edit it yourself.
