Definitions

  • a device for grinding long undulation waves of railway rails comprises a train of rotatable grinding wheels mounted on a rigid runner of a length greater than the longest undulation to be ground and oriented in the direction of the rail.
  • the runner is supported from a chassis rollable on the rails by means of a suspension such that the resultant of the driving force of the runner and of the force applying the grinding wheels against the rail passes substantially through the center of the active surface of the grinding wheels to avoid the development of a force tending to pivot the runner about a transverse axis.
  • the present invention provides for a train of grinding wheels mounted on a rigid runner, of a length greater than the longest undulation to be eliminated and extending in the direction of the rail and driven by a suspension to provide passage of the resultant of the driving force of the runner and of the force applying the grinding wheels against the rail through the center of the active surface of the grinding wheels.
  • the grinding may be effected in horizontal, vertical or inclined planes so as to be parallel to any one of the generatrix surfaces of the rail head.
  • a grinding vehicle may be fitted with several of these arrangements.
  • FIG. I is a side elevational view partly in section of a first embodiment forgrinding rails in a horizontal plane
  • FIG. 2 is an end view thereof partially in section
  • FIG. 3 is a plan view ofa detail of the grinding wheels of FIG. 1,
  • FIG. 4 is a side elevational view of a vehicle carrying second and third embodiments of a grinding means
  • FIG. 5 is a transverse sectional view through the third embodiment in FIG. 4,
  • FIG. 6 is a side elevational view of a particular arrangement of individually driven wheels applicable to the first embodiment
  • FIG. 7 is a top plan view of the arrangement in FIG.
  • FIGS. 8-10 are diagrammatic representations, of the force diagrams of the grinding apparatus with two further embodiments.
  • a runner formed by an elongate frame 1 rotatably supports four grinding wheels 2, 3, 4, 5.
  • the grinding wheels lie in a common plane, parallel to the longitudinal axis of the runner, itself oriented in the direction of the rail 6, over which it is suspended and advanced.
  • the support of the runner is such as to allow the run- .ner to oscillate, the axis of suspension of the runner passing through two trunnions 7 and 8, and being substantially in the-center of the horizontal active surface defined by the grinding wheels.
  • the trunnions 7 and 8 are supported at the ends of two stems 9 and 10, slidable in guides in the chassis ll of the vehicle transporting the runner.
  • the runner is free to travel up and down at will, but is advanced longitudinally along the rail under the power applied to the stems at the level of the trunnions 7 and 8.
  • FIG. 1 shows a long undulation on the rail surface, designated by 6 on evidently exaggerated scale as to its amplitude and it is evident that the length of the runner is greater than the undulation.
  • the grinding wheels are driven in rotation by a single motor 12 common to all the wheels, through gears 13, 14, 15 and 16 mounted on the shafts of respective grinding wheels 2, 3, 4 and 5.
  • Frame 1 and grinding wheels 2 to 5 can be raised and lowered to adjust the grinding pressure to values greater than or less than the weight of these elements, by pivotal connection of two jacks 17 and 18 between the ends of the frame l and the chassis 11.
  • FIG. 4 In the second embodiment at the left of FIG. 4 there is shown an arrangement identical to that previously described, except for the position of the wheels sup ported by the frame 19, suspended identically from the chassis20 of the vehicle.
  • the vehicle In FIG. 4, the vehicle is shown in entirety on the rail 21 to be worked.
  • the undulation to be corrected is not confined to the upper face of the rail head, but may extend over the lateral rounded part of the head, it is preferable to dispose, not only at least one grinding wheel to even off the top surface of the rail, but of grinding wheels for restoring the straightness of lateral rounded part of the rail head.
  • the third embodiment is shown at the right in FIG. 4 and in elevation in FIG. 5 and comprises a runner 26, extending parallel to the rail and supporting three grinding wheels 27, 28 and 29, disposed in a vertical plane for grinding the inner face of the rail head.
  • the grinding wheels 27, 28, 29 are driven, as in the case of the first embodiment, by a common motor 30 visible in FIG. 5.
  • the runner 26 can oscillate around a vertical median shaft 31, supported by a block 31'. adapted to be dis J placed horizontally in a direction grinding plane.
  • a jack 32 serves to displace the block 31' relative to perpendicular to the i the rail to adjust the pressure of the grinding wheels against the rail and thus, to determine the grinding pressure.
  • the suspension shaft 31 of the runner 26 is substantially in the grinding plane, to effect driving of the runner by a force in the grinding plane.
  • FIGS. 6 and 7 show a variation of the arrangement and driving of the grinding wheels in the case of grinding in horizontal plane.
  • the grinding wheels 33, 34, 35, 36, are supported by the frame 37 and are driven by individual motors 38, 39, 40 and 41.
  • the grinding wheels grind the rail 42, not by their face as in the previous embodiments, but by their peripheries.
  • the grinding wheels are vertical and form an angle with the longitudinal direction of the rail.
  • FIGS. 8 and 9 illustrate theoretically a suspension and the forces acting therein.
  • the grinding wheels 43 When operating, the grinding wheels 43 are subjected to a force R resisting their travel along the rail.
  • the force R must be overcome by the advancing force Ra pushing the wheel holding frame 44.
  • FIGS. 8 and 9 show that the identical result may be obtained, even when suspending the frame 44 at pivot 45, above the working plane.
  • F F it is indispensable to unbalance these forces as represented in the drawing where the jack F exerts greater force than jack F and in such a ratio that the resultant of the forces Ra and F and F passes substantially through the center of the active surface of the grinding wheels whereby to cancel any tendency of the frame to pivot fore and aft.
  • FIG. 10 Another embodiment based on a similar solution is shown in FIG. 10.
  • the frame 46 supporting the grinding wheels 47 is supported by a rigid connecting rod 48 supporting a part F, ofthe means for applying pressure ofthe wheels against the rail.
  • a second connecting rod is formed by a single jack 49 developing a force F 'lhese connecting rods are convergent, so that their developed forces intersect at point 0 located in the center of the active surface defined by the grinding wheels.
  • the jack or jacks can also be used for retracting the grinding wheels by raising the runners or frames when the device is out of service.
  • a rail repairing vehicle will, of course bear one device on each side, so as to simultaneously grind both rails of the travelled track.
