Definitions

  • Machines using pivoting grinding units controlled are currently used for reprofiling the rails because it is thus possible to reduce the number of grinding wheels necessary and therefore to make compact machines.
  • These machines with controlled pivoting grinding units as described in patents CH 606,616 or CH 633,336, have in particular the drawback of requiring, during each angular adjustment of the position of the grinding wheel, to reposition the grinding wheel against the rail to be ground.
  • the angular amplitude of the pivoting of the grinding units is limited.
  • a device for reprofiling the fungus of at least one rail comprising a support carrying at least one grinding unit, pivotally mounted about an axis parallel to the axis longitudinal of the rail, having at least one grinding wheel driven in rotation by a motor and means of axial displacement of this grinding wheel to apply it against a generator of the rail head and thus compensating for its wear.
  • This known device also comprises means for moving the pivot axis of the grinding unit, parallel to itself, in a direction perpendicular to the longitudinal axis of the rail.
  • the object of the present invention is therefore to produce a machine in which the grinding wheel (s) can pivot by a large angle, of approximately 180 °, that is to say by a much greater angle than on existing machines, while avoiding that during its pivoting, the grinding wheel does not come into conflict with the obstacles it might encounter on the way, such as fishplates, lag screws, etc.
  • the subject of the present invention is a reprofiling device comprising the characteristics listed in claim 1.
  • Figure 1 shows schematically the principle of moving a grinding wheel according to the present invention.
  • the center of the active surface moves in 01, 02, 03, 04 and 05 successively for successive angular positions of the grinding wheel offset by 45 ° in the example illustrated, but this active surface of the grinding wheel always remains in contact or at immediate proximity to the rail head.
  • Such movement of the grinding wheel 3 can be obtained by the combination of a rotation of the grinding unit about an axis parallel to the longitudinal axis of the rail and a movement of this pivot axis, parallel to itself, in a direction perpendicular to the longitudinal axis of the rail 11.
  • the first embodiment of the device for the continuous reprofiling of the head of at least one rail of a railway track comprises a carriage 1 provided with flanged wheels 2 which are preferably applied without play against the rails using adequate resources.
  • This carriage 1 is thus guided longitudinally and transversely by the rails and is connected to a rail vehicle (not shown) by means ensuring traction.
  • This carriage 1 is also connected to the rail vehicle by lifting means causing relative displacements in height between the carriage 1 and the rail vehicle.
  • At least one grinding unit is mounted so as to be angularly movable relative to the latter about an axis substantially parallel to the longitudinal axis of the rail.
  • Each grinding unit comprises a grinding wheel 3 driven in rotation by a motor 4 sliding with the aid of slides 5 on a yoke 6 parallel to the axis of rotation of the grinding wheel 3.
  • This axial rectilinear movement of the grinding unit allows to apply it with. a determined force against the surface of the rail head and to compensate for its wear.
  • a jack 7 connects the yoke 6 to the motor 4 and thus allows the wheel 3 to be applied against a generator of the rail to be ground with a determined force causing it to move. axial to compensate for the wear of the grinding wheel.
  • the yoke 6 comprises two concentric pins 8, constituting the pivot axis of the grinding unit, pivoted in a slide 9 sliding on transverse guide bars 10 of the carriage 1, that is to say extending perpendicularly in the longitudinal plane of symmetry of the carriage and therefore of the rail 11 to be ground.
  • the grinding unit 3, 4, 7 is mounted on the carriage 1 so as to pivot around an axis parallel to the longitudinal axis of the rail; this pivot axis being movable parallel to itself in a direction perpendicular to the axis of said rail.
  • this displacement of the axis perpendicular to the axis of the rail 11 is rectilinear but in variants it could be linear, curvilinear or other.
  • the grinding unit 3, 4, 7 comprises means for driving the latter in its pivoting movements around the axis materialized by its two pins 8.
  • These means comprise a toothed wheel 14 , integral with a pin 8, engaged with a helical screw 15 journalled in the slide 9 and driven in rotation for example by a stepping motor 16.
  • These means may also include, as in the example illustrated, a sensor 17 supplying an indicator i of the angular position of the helical screw 15 relative to the slide. This angular indication corresponds to the inclination of the grinding unit 3, 4, 7 relative to the carriage 1.
  • An electromagnetic brake 18 can be provided to lock the grinding unit in a given angular position, which is necessary so that the angular position of this grinding unit is fixed during a grinding operation in the selected position corresponding to the grinding of a determined generator of rail 11.
  • the grinding unit 3, 4, 7 also comprises means for moving the pivot axis of the grinding unit comprising a screw 19 cooperating with a part 20 fixed to the cross member 12 of the carriage forming nut.
  • This screw is pivoted in the holes of the slide 9 but cannot move axially relative to the latter:
  • a stepping motor 21 drives the screw 19 in rotation and moves the slide 9 along its guide bars 10.
  • Means are provided for slaving between them the pivoting of the grinding unit and the movement of its pivot axis.
  • these means are constituted by an electrical synchronization device S of the two stepping motors 16 and 21 so that the angular displacements of the grinding unit and the displacement of its pivot axis are such that the center 0 of the active surface of the grinding wheel 3 follows the line A of FIG. 1. In this way the grinding wheel 3 can pass from a horizontal position to a vertical position, its active surface always remaining substantially at the same distance from the surface of the rail head 11, or even in contact with it.
  • the axial stroke of the grinding wheel is practically reduced to the axial stroke necessary for compensating for the wear of the grinding wheel and for positioning it. removal, out of service. Under these conditions, the size of the grinding unit is greatly reduced and therefore the guidance of the grinding wheel is more precise.
  • the grinding wheel 3 has four degrees of freedom; pivoting about the pivot axis 8 of the grinding unit; a translation of this axis 8 in a direction perpendicular to the longitudinal axis of the rail, an axial displacement in the direction of the rail and a rotation about its own axis.
  • two translational drives 19, 20, 21 and two pivoting drives 15, 16 can be provided, respectively. on either side of the slides 5.
  • the mounting of the grinding unit 3, 4, 7 on the carriage 1 is the same as in the first embodiment, only the drive means of the unit in its pivoting and driving the pivot axis of the grinding unit in its movements, are different.
  • a sensor 25 delivers an indication relating to the inclination of the grinding unit as a function of the linear position of the piston of the jack 22.
  • a position sensor 27 delivers an indication of the position of the slide 9 relative to the carriage 1 to a position indicator i.
  • a servo device S causes the cylinders to be supplied with working fluid in a synchronized manner so that the center 0 of the active surface of the grinding wheel 3 follows the path A illustrated in FIG. 1 so that for all the inclinations from the grinding wheel its distance from the rail head remains substantially constant.
  • the grinding unit 3, 4, 7 sliding in the yoke 6 is pivotally mounted via the pins 8 of the yoke 6 on the free end of levers 32 the other end of which is pivoted on the crosspieces 12 of the carriage 1.
  • These levers are actuated in angular framings around their articulation on the crosspieces 12 by jacks 33 fixed to the carriage and the piston of which is connected to the middle part of the lever 32.
  • pin (s) 8 are integral with toothed wheels 28 meshing with the internal toothing of toothed rings 29 which they are integral with the carriage.
  • a desmodromic connection is produced between the pivoting of the grinding unit and the displacement of its pivot axis which here always takes place parallel to itself and in directions perpendicular to the axis of the rail 11 but following a circular and no longer straight path.
  • the number of teeth of the crowns 29 and of the toothed wheels 28 is such that the center of the active surface of the grinding wheel 3 travels along the path A of FIG. 1 during the angular displacements of the levers 32.
  • the grinding unit is mounted on its support carriage so as to be able to pivot around an axis parallel to the longitudinal axis of the rail and so on the other hand that its pivot axis jointly undergoes a translation perpendicular to the longitudinal axis of the rail.
  • the grinding units can include grindstones, lapidaries or peripherals.
