Definitions

  • the present invention relates to the rectification and more particularly to the final polishing of the rails of a railroad track by grinding and / or reprofiling of the rails of a railroad track and in particular in the tight curves thereof.
  • GB-A-1,151,010 a device for the reprofiling of the mushroom of at least one rail comprising a support carrying at least one grinding unit, having at least one grinding wheel driven in rotation by a motor and means for axial displacement of this grinding wheel to apply it against a generator of the rail head and thus compensating for its wear.
  • a problem which arises for rail reprofiling machines is to be able, with the same wheel, to grind the internal leave, the rolling table and the external leave of the rail. This is especially essential when preparing rails for scaffolding. With existing machines, this can only be done with long manual adjustments and bulky grinding units, their axial stroke, parallel to the axis of rotation of the grinding wheel, must be large, finally these large axial strokes affect the precision of grinding.
  • Patent EP 0 145 919 describes a machine in which the grinding wheel (s) can pivot by a wide angle, of approximately 180 °, that is to say by a much greater angle than on previous machines, while avoiding that during its pivoting the grinding wheel does not conflict with obstacles it might encounter on the way, such as fishplates, lag screws, etc.
  • a change in the inclination of the grinding wheel is prevented from causing a significant correction of its axial position, parallel to its axis of rotation, to bring it back into contact with the rail.
  • the grinding units are mounted on carriages or chassis suspended under a railway vehicle and rest on one of the rails by guide rollers.
  • the grinding reference plane is defined by the running surface of the working rail and not by the plane of the track.
  • the plane of the tread table thereof is modified so that the reprofiling of the rail is carried out on the basis of an imprecise reference plane.
  • pivoting grinding units comprising a motor driving two rotating grinding wheels, the height of these units requires a large available space under the rail vehicle and it becomes difficult to accommodate trolleys under it. guide.
  • the reprofiling device described in patent CH 675,440 overcomes this drawback by mounting the grinding units on the chassis of a railway vehicle comprising a two-wheeled axle at one of its ends and articulated around an axis parallel to the longitudinal axis of the track at its other end on a rigid frame having two wheels. In this way the chassis is guided by the track and defines a reference plane parallel to the track plane.
  • All the above-mentioned devices use grinding wheels whose working face is flat and which therefore leave longitudinal facets after grinding on the rail head.
  • the use of lapidary grindstones creates grooves, transverse to the rail. These facets and these streaks during high power grinding can be significant and negatively influence the fatigue strength of the rail.
  • Grinding devices are also known as described in the patents DE-26 12 174 (cf. preamble to claim 1) and DE-26 12 173 in which the grinding units are pivotally mounted on a frame itself mounted so as to move vertically relative to a trolley rolling on the track.
  • This carriage is extendable laterally and comprises means tending to move it apart so that its flanged wheels are always applied against the inner flank of the rail to guide this carriage along the track.
  • This device comprises, unlike the previous one, grinding wheels of form reprofiling a relatively long length of the perimeter of the profile of the rail head and not only a straight facet of small width thereof.
  • the bearing force will be equal and opposite to that exerted on the outer rail, increased by the component of the weight of the corresponding carriage, therefore this bearing force is very high.
  • the rails are laid with an overlap of 15 to 35 mm depending on the networks and the rolling stock.
  • the axis of the grinding wheel is offset by a value equal to the deflection between the rollers of the carriage increased the gauge of the track. This significant offset from the axis of the grinding wheel results in a lowering of the lower angle of the grinding wheel which can go up to 50 mm and more for a grinding wheel inclined at 45 °. This is not acceptable because the grinding wheel interferes in particular with the fasteners of the rail leading to ruptures of grinding wheels.
  • the carriages extendable transversely must exert on the flanges of the wheels a very high spacing force to compensate for the cant components of the weight of the carriage in its entirety, as well as the weight of the grinding units and the grinding support forces. Due to this high spacing force, derailments of the carriages are frequent, particularly when the rails exhibit chamfering wear.
  • the object of the present invention is to produce a device for reprofiling the rails of a railroad track in which the guide of the grinding units with respect to the rail is very precise using simple means and which also eliminates any risk of derailment of the carriage.
  • the present invention naturally obviates all the aforementioned drawbacks and makes it possible to obtain perfect reprofiling.
  • the subject of the present invention is a device for grinding the surface of the head of at least one rail of a railway track comprising a rigid frame connected to the chassis of a railway vehicle, by lifting means for walking up and down. -foot of the vehicle; this frame being guided along the track; device comprising at least one grinding unit formed by an assembly of at least one grinding wheel, driven in rotation by a motor, each assembly constituting a grinding unit being mounted on a corresponding support in a linearly movable manner so as to bring the distance or distance wheel surface grinding wheel; and in which the axis of each grinding wheel is situated in a plane perpendicular to the longitudinal axis of the rail; characterized in that each support is mounted independently on the frame by means of translation allowing this support to move relative to the frame transversely to the rail; and by the fact that each support comprises at least one support roller and support means, connecting this support to the frame and tending to apply this support roller against one of the sides of the rail in the immediate vicinity of the corresponding grinding unit.

  • the licensee designed that it was necessary to make a pass for finishing or polishing the rail. with a special polishing unit, whose grinding wheel is a shaped grinding wheel, therefore in contact with a large and therefore curved portion of the surface of the rail head. It is also necessary that this shaped wheel has a constant off-center such that the normal to the radius connecting the axis of the wheel to each of its points of contact with the rail is parallel to the axis of the rail. In doing so, the facets and transverse ridges have been eliminated and by constant off-centering, i.e. precise positioning of the grinding wheel relative to the rail and no longer relative to the track, it is possible to avoid any deterioration of the shaped grinding wheel. and to ensure an unequaled precision in the reprofiling of the rail head.

It is understood that to guarantee such positioning of the grinding wheel of form 3 relative to rail 1, very precise guiding of the grinding wheel is required relative to rail 1.
  • FIG. 2 shows the principle of this guidance by a roller 5 journalled on an axis 6 secured to the support 7 of the grinding wheel.
  • FIG. 2 also schematically illustrates the use of two grinding wheels of form 3.3a each machining a part (A-B; C-D) of the perimeter P of the head 2 of the rail 1, parts which moreover overlap over a certain length (C-B).
  • the wheels 3.3a are thus guided directly by the rail using the roller 5, this roller also being located in the immediate vicinity of the wheels in the longitudinal direction of the rail, the theoretical optimum being to accommodate this roller in the plane containing the axis of the grinding wheel.
