Definitions

  • This invention relates to a tangential grinding machine.
  • Tangential grinding machines comprising a grinding device consisting essentially of a grinding wheel of abrasive material which when rotated removes by abrasion a part of the material with which it comes into contact.
  • each grinding device consists generally of a disc of abrasive material, or grinding wheel, built to operate with its circumferential edge.
  • a further drawback of a tangential grinding wheel is the fact that to reprofile a rail a system with a negative contour is required, such a system being of high cost.
  • cup-type grinding wheels generally have to work on both rails simultaneously for mass balancing reasons. This makes it more difficult to carry out grinding work on a single rail, such as the central earth rail or the outer live lateral rail for subway trains.
  • FR-A-2.703.084 describes a machine for grinding rails of a railway track.
  • This machine is of the type comprising a main chassis and at least one grinding module comprising at least one chassis supported by two wheels bearing on the same rail and mounted on the main chassis, at least one grinding unit provided with a grinding head and with a motor for rotationally driving the grinder of this head, a device for supporting the grinding head, which device is articulated to the said module chassis so that it can pivot about the rail in a plane perpendicular to this rail and a device for controlling the angular positioning of the grinding head.
  • DE-A-2.612.174 describes a mobile rail grinding machine for grinding the running surface of the rails of a track comprising a grinding module mounted for power-driven vertical movements on a machine frame which runs on undercarriages on the track rails
  • a grinding machine is provided as described in claim 1.
  • the machine comprises a base frame 2 mounted on four wheels 4 which run on the rails 6 to be ground.
  • the grinding units 8 are movable transversely to the base frame 2 driven by hydraulic systems 14 (only one system is shown on the figures).
  • Each grinding unit 8 comprises a frame 9 formed from two parallel longitudinal members 16 joined together by cross-members 18, at the junctions between the longitudinal members and cross-members there being provided four uprights 20 for stiffening the frame.
  • the upper ends of the uprights are connected together by beams 22 provided with two guide arms 24 which engage in the uprights 26 of the grinding unit 8.
  • beams 22 provided with two guide arms 24 which engage in the uprights 26 of the grinding unit 8.
  • a further pair of arms 24 parallel to the aforesaid to enable the frame 9 to be moved vertically in a rigid manner relative to the grinding unit 8.
  • Said vertical movement is achieved by means of a plurality of pneumatic systems 28 fixed to the grinding unit 8 and having their rods rigid with the frame 9.
  • the force required at any given time for the various operations can be set by a pressure regulator (not shown on the drawings).
  • the frame 9 comprises a pair of bushes 30 in which there engage two pins 31 oppositely projecting from the longitudinal edges of a rocking platform 32.
  • the rocking platform consists of a rectangular frame 34 to which there are hinged, on a longitudinal side, two plates 36 which can be spaced apart at the other longitudinal side by a screw mechanism 35.
  • the plates 36 are hinged to the rectangular frame 34 on different sides.
  • Each plate 36 is fixed to a corresponding flange 38 provided with brackets 40 for securing an abrasive grinding wheel 42.
  • Each flange 38 can be adjusted by axial rotation relative to the overlying plate 36 and can be locked relative to it by bolts which engage in a plurality of corresponding holes 44.
  • Each grinding wheel 42 can be rotatably driven by a pulley 46 rigid with the shaft of a corresponding electric motor 48 mounted on the flange 38.
  • Each flange 38 is also provided with pairs of slotted holes 49 to enable it to be shifted outwards relative to the overlying plate so that the two grinding wheels 42 are not longitudinally aligned with each other, but are positioned on opposite sides of the centre line of the rail 6 to be ground.
  • each grinding wheel 42 has its axis of rotation non-parallel with the rolling surface of the track, and because of the facility for axially rotating the flange 38 relative to the plate 36 the two grinding wheels 42 can be inclined inwards relative to the direction of advancement along the rail.
  • the angle between the grinding wheel axis and the horizontal plane of the rail varies, and on varying the position of the flange 38 to the plate 36, the angle between the grinding wheel axis and the rail axis (convergence) varies.
  • the machine of the invention also uses a plurality of reference sensors for the rail position, which activate the various controls for effecting the grinding cycle.
  • the machine To operate the machine, it has firstly to be transferred to the site on which the rail to be ground is located. This transfer is preferably done by a locomotive 50, which can also be provided with an electrical generator unit 52 for remotely powering the grinding machine, especially if the railway line is not electrified or if the power supply has been temporarily switched off for maintenance reasons.
  • a locomotive 50 which can also be provided with an electrical generator unit 52 for remotely powering the grinding machine, especially if the railway line is not electrified or if the power supply has been temporarily switched off for maintenance reasons.
  • the horizontal cylinder-piston units 14 are then operated to transversely move the units 8 until the sensors sense the position of the rail 6 and halt the travel of the frame 9. At this point the frame is lowered by the pneumatic system 28 such that the grinding wheels 42 make contact with the rail head 53. During this operation the frame descends substantially rigidly as the arms 24, 24' are guided within the uprights 26.
  • the motors 48 are then operated to rotate the grinding wheels, which perform their abrasive action with a working pressure suitably regulated by the aforesaid pressure reducers.
  • a working pressure suitably regulated by the aforesaid pressure reducers.
  • the rail can be restored by using grinding wheels in which the profile is defined at the grinding wheel preparation stage by setting it at a particular inclination, convergence and shift with respect to the rail.
  • the flange 38 can also be shifted relative to the plate 36 to vary the position of the grinding wheel centre line about the rail axis.
  • These two units 54 have the function of supporting, in the case of deformation of the horizontal surface of the rail, the grinding wheel which is near this surface.
