Definitions

  • the invention relates to a rail grinding machine, consisting of a first base frame arranged with rollers on a first rail for receiving a grinding device, and a second base frame arranged with rollers on a second rail for receiving a single track device, by means of which the second base frame transversely to Rail longitudinal direction is adjustable relative to the first base frame.
  • a corresponding rail grinding machine is known per se (European patent application No. 90 120 502).
  • a first and a second grinding device are arranged on a base frame, with the first grinding device processing the rail surface in the longitudinal direction and the second grinding device processing the rail surface transversely to the longitudinal direction.
  • Both grinding devices are arranged on the base frame, which is supported on the parallel running rail tracks by means of correspondingly mounted rollers.
  • the distance between the parallel running rollers is changed by means of a hydraulically operated cylinder which is arranged between two parts of the device.
  • this cylinder cannot be used for automatic fine adjustment, as is necessary, for example, in curves. Especially in curves, however, it would be desirable if the track could change automatically.
  • the invention has for its object to provide a corresponding device for a rail grinding machine of the type mentioned, by means of which an engagement and an automatic adaptation of the rollers to any track changes is guaranteed and thus tilting of the rail grinding machine on the track is prevented.
  • the second base frame is arranged on a guide tube fastened to the first base frame and can be adjusted transversely to the longitudinal direction of the rail relative to the first base frame against the pressure of at least one energy accumulator in such a way that the two rollers arranged on the second base frame are moved by the restoring force of the
  • the energy storage device is arranged resiliently against the second running rail.
  • FIG. 1 shows a rail grinding machine, designated as a whole by 100, which essentially comprises a first base frame 30 designed to hold a first grinding device 10 and a second grinding device 20.
  • first base frame 30 designed to hold a first grinding device 10 and a second grinding device 20.
  • rollers 31 and 32 which are arranged at a distance from one another and are arranged on the one rail 2 of a track 1 formed from two rails 2, 2 'arranged parallel to one another.
  • Corresponding guide rollers 3 and 4 are also provided on the base frame 30.
  • the first grinding device 10 is used to machine the rail surface in the longitudinal direction and the second grinding device 20 is used to process the rail in the transverse direction.
  • the two grinding devices 10 and 20 are designed to be height-adjustable relative to the rail surface via elements (not shown) in the direction of the arrows Z and Z '.
  • the first grinding device 10 can also be pivoted in the arrow direction X ′ about an axis body 11 oriented transversely to the transport direction X of the rail grinding machine 100.
  • the second grinding device 20 is transverse to the longitudinal direction of the rails 2, 2 'by means of a corresponding adjusting device 21 adjustable.
  • a single-track device 75 Arranged on the side opposite the first grinding device 10 is a single-track device 75 designed for so-called single-railing of the entire rail grinding machine 100, which is described in detail below.
  • FIG. 2 shows the single track device 75 shown in view and one can see a second base frame 45, two spaced-apart rollers 31 'and 32' on the other rail 2 'of the track 1, which correspond to those on the first base frame 30 (FIG. 1) mounted rollers 31 and 32 are arranged.
  • a support frame 50 for a spindle device 60 is arranged on the second base frame 45, which is operatively connected to the first base frame 30.
  • the second base frame 45 for the single-track operation of the rail grinding machine can be adjusted relative to the first base frame 30, i.e., transversely to the transport or longitudinal track direction.
  • the second base frame 45 essentially comprises a first frame part 40 which is operatively connected to the first base frame 30 and a second frame part 46.
  • the two frame parts 40 and 46 are over a guide tube 44 is operatively connected to one another such that the second frame part 46 is adjustable relative to the first frame part 40.
  • the first frame part 40 has a side member 41 and two side parts 42, 42 'and is fixedly connected to the opposite first base frame 30 in a manner not shown.
  • the second frame part 46 has two longitudinal beams 46 ′, 46 ′′ arranged at a parallel distance from one another and two side parts 47, 47 ′ arranged thereon.
  • the two track rollers 31 'and 32' are arranged between the two longitudinal beams 46 'and 46''and are mounted accordingly.
  • the longitudinal beams 46 ', 46'' are operatively connected to one another by correspondingly arranged tabs 48, 48'.
  • the second frame part 46 is essentially supported with the side parts 47 and 47 'on the side parts 42 and 42' of the first frame part 40 and is connected to one another by the guide tube 44 such that, as already mentioned above, the second frame part 46 with the rollers 31 ' , 32 'for the single track operation relative to the first frame part 40, ie, transverse to the longitudinal direction of the track 1 in the arrow direction Y is adjustable.
  • the two frame parts 40 and 46 are operatively connected to one another by the guide tube 44 penetrating the frame parts and by two spring elements, preferably by two gas pressure springs 49, 49 '.
  • the two gas pressure springs 49, 49 ' are arranged at one end on the side parts 42, 42' of the first frame part 40 and at the other end on the side parts 47, 47 'of the second frame part 46 and fastened accordingly.
  • FIG. 4 shows a side view in the direction of the arrow IV in FIG. 2 of a portion of the single track device 75 with the support frame 50 and the spindle device 60 and one can also see the schematically illustrated base frame 30, the first frame part 40 and the guide tube 44, which has one end 44 ′′ penetrates the side member 41 and with the other end 44 ′ the two side members 46 ′, 46 ′′ (FIG. 3) of the second frame part 46. Furthermore, one can recognize the gas pressure spring 49 'and the one roller 31'.
  • the support frame 50 On the one longitudinal beam 46 '(FIG. 3) of the second frame part 46, the support frame 50, designated in its entirety by 50, for the spindle device 60 is arranged.
  • the support frame 50 is arranged and fastened to the second frame part 46 with a first support part 51 designed for mounting the spindle device 60.
  • a bearing piece 43 ′ for a threaded spindle 62 of the spindle device 60 is provided on the support part 43.
  • FIG. 5 shows, in a sectional view and on a larger scale, a section of the spindle device 60 according to FIG. 2 and one recognizes the support part 51 of the support frame 50 provided with a corresponding opening 51 'for the threaded spindle 62. for example fastened by means of a holding piece 64.
  • the holding piece 64 is provided with a recess 64 ', in which a flange piece 65' of a spindle nut 65 is arranged.
  • the spindle nut 65 is operatively connected to a hub 61 'of a handwheel 61 of the spindle device 60 via a wedge 63 or the like.
  • the handwheel 61 For rough adjustment of the distance between the rollers 31 'and 32' mounted on the frame part 46 of the second base frame 45, relative to the rollers 31 and 32 mounted on the first base frame 30, the handwheel 61 is rotated accordingly.
  • the spindle nut 65 which is operatively connected to the handwheel 61, is correspondingly moved on the fixed threaded spindle 62 and, at the same time, the second frame part 46 mounted on the guide tube 44 with the support frame 50, as indicated by the direction of the arrow Y in FIG.
  • the rough adjustment is carried out in such a way that the two rollers 31 'and 32' with their guides, which are not described in more detail, are at a short distance from the rail body.
  • the frame part 46 with the two rollers 31 ', 32' is pressed against the rail 2 'by the restoring force of the gas pressure springs 49,49' in the arrow direction Y ', as shown in FIG.
  • the resilient restoring force of the gas pressure springs 49, 49 'it is achieved that the two rollers 31' and 32 'with the frame part 46 in the event of any lane changes or in curves depend on the respective distance between the two Automatically adjusts rails 2,2 '.
  • the single-track device 75 described above can be attached to existing rail grinding machines in a simple manner. For this purpose, only the fixed base frame 30 is to be correspondingly coupled to the base frame 45 or slidably mounted on the guide tube 44.
