Definitions

  • the present invention relates to a grinding device for reprofiling on track and a continuous track rails according to the preamble of the main claim.
  • This technique is no longer used because it has the disadvantage of leaving a sinusoidal trace on the rail resulting from the sinusoid described by the two edges of the grinding wheel during its advance, and that of creating a discontinuity between the sections thus ground one following the others. These traces of grinding and this discontinuity between ground sections are no longer admissible with the current circulation speeds of convoys. Finally, as described in this patent, this grinding device does not make it possible to reconstitute the curvilinear profile of the rails because it only allows a plane grinding of the running surface of the rails.
  • the first solution consists in adding to the grinding device a device for periodic reshaping of the active surface of the grinding wheel by means of diamond tools.
  • This solution is advantageous in the case of the use of shaped grindstones whose active surface has a cross section conforming to the original curvature of a portion of the profile of the rail head, but it requires frequent checks of the work carried out to decide of the advisability of a reshaping operation, and the installation of such devices is costly.
  • the consumption of the wheel is important.
  • the second solution which avoids the deformation of the active surface of the grinding wheels and its consequences, consists in using flat lapidary grinding stones working on the face and no longer on the periphery; but the size of these lapidaries poses problems when the rail to be ground is surrounded by obstacles such as for example level crossings and counter rails.
  • the device according to the invention provides a solution making it possible to avoid the drawbacks mentioned. It allows the use of grinding wheels with a peripheral active surface, of low space, at high cutting speed and with progressive attack allowing great depths of pass, without however requiring the addition of a reprofiling device, the back-and-forth movement printed on the grinding wheel having the effect of regularly distributing its wear over the entire width of its active surface and sand leaving sinusoidal traces of grinding inherent in the combination of the movements of forward and back and forth of the grinding wheel.
  • the device shown in FIGS. 1 and 2 is suitable for correcting them by grinding the burrs affecting the clearance of the head from a rail 1.
  • This device comprises a chassis 2 in the form of a bridge resting on the rail 1 by two pairs of rollers 3 with lateral flange 30. Each pair of rollers 3 is mounted on a double lifting beam 4 articulated to a foot 5 of said chassis 2.
  • a cylindrical grinding wheel 6 with rectilinear generators is driven in rotation by a motor 7 fixed to a movable support 8.
  • This support 8 is journalled on an eccentric shaft 9 pivoted in two consoles 10 and 11 fixed to the longitudinal member 12 of the chassis 2.
  • a motor-reduction unit 13 for driving the eccentric shaft 9 is fixed on the console 11.
  • a double-acting hydraulic cylinder 14 is articulated by its cylinder on a console 15, fixed to the side member 12 of the chassis 2, and by the piston rod on a fitting 16 fixed to the motor 7 for driving the grinding wheel 6.
  • the chassis 2 is intended to be connected in the usual way to a railway vehicle having the function of moving along a railway track to be ground. Means are provided for applying it vertically and laterally against a line of rails of the track with a determined force.
  • the cylindrical grinding wheel 6 works by its periphery, the generators of which in contact with the rail 1 are oriented parallel to a tangent of the profile of the mushroom chosen as a function of the deformation to be corrected, here according to an oblique tangent to the part of the contour of the leave outside where the burr is formed.
  • the mobile support 8 on which the grinding wheel 6 is fixed and its drive motor 7 is journalled on the eccentric shaft 9 so that the resulting reciprocating movement is transverse to the rail 1.
  • the axis of rotation of the grinding wheel is perpendicular to the rail and the eccentric shaft 9 is parallel to the rail.
  • the hydraulic cylinder 14 controls the grinding pressure and the rail 1 acts as a guide for the reciprocating movement of the grinding wheel 6.
  • the cylinder 14 is connected to a supply circuit, not shown, controlled by a value pressure preset as a function of the desired depth of pass, itself a function of the amplitude of the deformation to be corrected.
  • An example of such a circuit includes a pressure control valve connected between the pressurized fluid supply pump and one of the two chambers of the hydraulic pack suspension cylinder , here the hydraulic cylinder 14.
  • the adjusting member of this valve is controlled for example by the operator by displaying a preset value according to the desired depth of pass.
  • the amplitude a of the back and forth movement is substantially equal to a preset value which is a function of both the width of the grinding wheel used and the width of the ground part of the profile of the rail head, according to a relation ⁇ - / - f illustrated by Figures 3 and 4.
  • the values a and f of the relation ⁇ - / - f are those of the projections of the amplitude of the movement back and forth and the width of the grinding wheel in a plane perpendicular to the rail.
  • the device described combines the advantages of permanent self-reshaping of the grinding wheel by the rail with those of peripheral grinding while avoiding the formation of grooves in the rail, which also makes it possible to save time and material.
  • the grinding wheel 6, seen according to arrow F in FIG. 2 is arranged obliquely relative to the rail.
  • the back-and-forth movement, represented by the arrow T takes place either in the direction of the axis of rotation of the grinding wheel (FIG. 6), or obliquely with respect to said axis of rotation (FIG. 5).
  • the position of the motor 7 on the movable support 8 and the orientation in space of the eccentric shaft 9 obviously depend on the orientation given to the grinding wheel 6.
  • the motor 7 for driving the grinding wheel 6 can be independent of the mobile support 8 and / or of the grinding wheel 6 and connected to the latter by a transmission.
  • the back and forth movement is obtained by a translation.
  • the grinding wheel 6 is mounted on a shaft 31 guided in a bearing 32 carried by an arm, not shown, articulated to the chassis 2.
  • the free end of the shaft 31 is provided with an annular shoulder 33 journalled in a clamp 34 of which it is thus integral axially.
  • This bush 34 is connected by a connecting rod 35 to the crank pin 51 of a crankshaft 36 driven in rotation by a motor-reduction unit 37.
  • the shaft 31 is driven in rotation, by means of a transmission by pulleys, 38, 39 and belt 40, using a motor 41 fixed on the bearing 32.
  • the crankpin 51 is fixed in a radial groove 52, of the crankshaft plate 36.
  • This adjustment is made by modifying the radial difference between the crankpin 51 and the axis of rotation of the crankshaft 36 by displacement of said crankpin along the groove 52.
  • the eccentricity of the shaft 9 is modified to adjust the value of the amplitude a.
  • the grinding wheel 42 is frustoconical and the back and forth movement is directed in a direction close to those of the generators of contact of the frustoconical wheel with the rail.
  • the motor 43 of the grinding wheel 6 is mounted on a support 44 pivoting about a fixed axis 45 offset in a plane transverse to the line of rails 1 and secured to the chassis 2.
  • the opposite end of the support 44 is driven in a reciprocating movement of the pendulum type by a rod-crank drive 46 along a path T 1 in an arc.
  • This trajectory T 1 is substantially transverse with respect to the file of rails 1 and has as its center the pivot axis 45 of the support 44.
  • the motor 47 of the grinding wheel 6 is pivotally mounted around a fixed axis 48 offset in a plane transverse to the line of rails 1 and carried by a console 49 secured to the chassis 2.
  • the motor 47 of the grinding wheel is driven around its pivot axis 48 in a pendulum-type reciprocating movement by a rod-crank drive 50 along a path T 2 in an arc of a circle oriented substantially in the direction of the line of rails 1 and having as its center the pivot axis 48 of the motor 47.
  • the lever arms of the movable elements are determined so that the projection A of the path T 2 in a plane perpendicular to the line of rails 1 or, in this case also equal to the value a defined by the relation a ⁇ / -f.
  • each unit 53 and 54 the two grinding wheels 6 are mounted according to the principle of the variant shown in FIG. 9, that is to say pivoting around a deported shaft 52, but oriented at an angle relative to the line rails 1.
  • the motors of the two grinding wheels of each unit are fixed on a common frame 55 mounted to pivot and slide within predetermined limits on one of the two trees 52.
  • These two trees 52 are rigidly fixed to the frame 100 and each of the two frames 55 is connected audi chassis by a grinding depth adjustment cylinder, not shown, of the type already described in the first embodiment shown in Figures 1 and 2.
  • Each frame 55 is connected by a connecting rod 56 to a drive mechanism in a back and forth movement comes common constituted by a crankshaft 58 actuated in rotation by a reduction engine group 59 fixed to the chassis 100.
  • This last variant makes it possible to increase the grinding capacity of the device and its use at high speed of movement along the rail 1.
  • the adjustment of the cutting depth of the grinding wheel can be carried out directly and manually, without slaving to a preset displayed value.
  • the device will simply include, in place of the jack 14, a screw-nut connection controlled by a handwheel for example.
  • the set of mechanisms (8 to 13) actuating the grinding wheel 6 in its combined rotational and reciprocating movements will be connected to the chassis 2 by the intermediate of an adjustable frame in a transverse plan to the track.
  • several of these assemblies each comprising a grinding wheel may be mounted on the same chassis, each oriented in a different direction appropriate to the deformation to be corrected.
  • the whole of the mobile assembly is mounted on the chassis by means of a mobile support relative to the chassis 2 (not shown) to allow adjusting the cutting depth of the grinding wheel and compensating for its wear.
