  • the drive motor 3 is rigidly fixed to a gusset 4 secured to the chamber 5 of a double-acting cylinder whose piston 6 is secured to a guide column 7 passing right through the chamber 5.
  • This column guide 7 is secured to a support 8 fixed with bolts 9 to a carriage 10 of a railway vehicle. Due to the lights 11 of the support 8 it can be fixed on the carriage 10 according to several orientations so as to vary the position of the grinding wheel 1 relative to the rail 12 according to the part of the head of the rail that is to be reprofiled .
  • the guide column 7 is provided with conduits 13, 14 opening on one side and the other of the piston 6 in the chamber 5 of the hydraulic or pneumatic cylinder 5, 6.
  • the angle included between the axis of the jack 5, 6 causing the advance movement of the grinding wheel 1, displacement defining the depth of cutting and compensating for the wear of the grinding wheel, and the axis of rotation of the grinding wheel 1 is of the order of 30 °. This angle can be chosen within very wide limits depending on the portion of the rail to be reprofiled.
  • this angle ⁇ is substantially equal to half the angle at the apex a of the conical grinding wheel 1, so that the direction of advance of the grinding wheel 1 towards the rail 12 is substantially parallel to the external generator. the grinding wheel in the vicinity of the point of contact of the latter with the rail.
  • the grinding device is positioned relative to the track so that a counter rail, a signaling box or any other obstacle located along the track is outside the zone in which the grinding wheel moves during the advance of the vehicle along the track.
  • the axis of rotation of the grinding wheel 1 forms an angle ⁇ with the direction of advance of this grinding wheel defined by the axis of the jack 5, 6, 7.
  • the front working surface of the grinding wheel 1 is of frustoconical shape and intersects the peripheral surface of the grinding wheel, also tapered, approximately at right angles.
  • This arrangement is particularly advantageous for reprofiling the upper running surface of the rail 12. It is seen that thanks to this arrangement this upper running surface of the rail can be reprofiled even at level crossings where the rail 12 is practically buried in the roadway.
  • angle f between the axis of rotation of the grinding wheel and the direction of advance of the latter, namely the axis of the jack 5, 6, 7, is substantially equal to half the angle at apex a of the conical grinding wheel 1 and the advancement of the grinding wheel takes place substantially parallel to its generator in the vicinity of its point of contact with the rail.
  • the support 8 can in this embodiment be mounted on the carriage as illustrated for example in Figure 1. Thus, it is possible to tilt the grinding wheel relative to the rail to be reprofiled according to the portion of the rolling table to be reprofiled.
  • Figure 4 illustrates an embodiment of the grinding device used for reprofiling the lateral face of the rail head.
  • the conical wheel 1 is rotated by the motor 3 along a horizontal axis.
  • the gusset 4 secured to the motor 3 slides on two bars 15 secured to the support 8.
  • a lug of the gusset 4 is articulated on the rod 16 of a double-acting cylinder 17 controlling the advance travel of the grinding wheel 1.

  • This angle has been chosen here substantially equal to 45 ° and the angle at the top of the grinding wheel 1 is approximately equal to 90 °.
  • the support 8 can be moved angularly relative to the tool carriage 10 to allow grinding different portions of the surface of the rail head.
  • This movement is a rotation around an axis parallel to the rail, in the examples illustrated around a fictitious axis located inside the rail, more precisely the head of the rail.
  • This movement does not modify the angle between the direction of advance of the grinding wheel and its axis of rotation but allows the direction in which the grinding wheel is moved relative to the rail to be adjusted.
  • FIG. 7 illustrates a railway vehicle for reprofiling the rails of a railway track provided with two tool-carrying carriages 18, 19, rolling on the rail using flanged wheels 20, connected to the chassis of the vehicle on the one hand by drive links 21, 22 of the carriage along the rail and on the other hand by articulated links comprising jacks 23, 24 making it possible to move the carriage vertically relative to the chassis of the vehicle and also allowing d 'apply the carriages against the rail 12 with a determined force.
  • each carriage carries two grinding devices each having two working units formed by a drive motor 25 and a conical grinding wheel 26.
  • the two working units of the same grinding device are rigidly connected together by a support 27.
  • levers forming a deformable parallelogram The connection of this support 27 to the carriage 18 is carried out using levers forming a deformable parallelogram.
  • Two parallel levers 28, 29 are pivoted at one of their ends on the carriage at 30, 31 respectively.
  • the free end of the lever 28 is pivoted at 32 on one of the ends of a connecting rod 33, the other end of which is pivoted on the support 27.
  • the free end of the lever 29 is pivoted at 34 on the connecting rod 33.
  • the distances between the pivot points 30, 31 and 32, 34 as well as the pivot points 30, 32 and 31, 34 are respectively equal so as to form a deformable parallelogram.
  • the connecting rod 33 extends vertically like the line connecting the pivot points 30 and 31.
  • the end of the lever 28 pivoted on the carriage includes an ear 35 articulated on the housing of a double-acting cylinder 36 whose rod 37, integral with the piston, is pivoted on an ear 38 which has the end of the pivoted lever 29 on the connecting rod 33.
  • the axis of rotation of the grinding wheels 26 is not confused with the direction of advance of these grinding wheels, controlled by the connecting rod 33, but forms an angle with respect to this direction. This angle can be adjusted by modifying the angular position of each working unit relative to the support 27.
  • the entire parallelogram device described above can be pivoted around axes 39 in order to be able to orient the advance movement of the grinding wheels as a function of the area of the rail profile to be ground.
  • FIG. 6 is a partial and schematic view along the line VV of Figure 5.
  • each motor unit 25 - grinding wheel 26 is adjusted with another inclination relative to the rail so as to reprofile different portions of the surface of the head of the rail.
  • the pivoting which the motor unit 25 - grinding wheel 26 can carry out relative to the support 27 is preferably carried out in an arc centered on a fictitious axis parallel to the rail 12, that is to say in the direction of movement of the vehicle, this fictitious axis being located in the rail.
  • the units can be inclined either inside the track with an angle f, or outside the track with the angle il without interfering with the obstacles located along the track .
  • the grinding wheel takes an inclined position and its lower peripheral part re is in contact with the rail.
  • Most of the grinding wheel is located above the rail outside the area occupied by obstacles. Thanks to this arrangement, we are able to keep the grinding stones working against the rail permanently even when passing obstacles such as level crossings, signal boxes, counter-rails, etc., which saves appreciable time, ensures high reprofiling precision and above all regular grinding since the grinding wheels are always in contact with the rail.
  • the size of the wheel relative to obstacles remains the same regardless of the advance of the wheel.
