Definitions

  • the present invention relates to continuous measurement on the way of the shape of the transverse profile of the useful portion of the head of a rail of a railroad track.
  • useful portion of the head is meant that serving as a support for vehicle wheels, and in particular the running surface, the leaves and the upper part of the inner face of the rail.
  • Patent CH 606,616 which describes a measuring device comprising a series of feelers arranged side by side around the tread table, the fillet and the inner face of the rail head, is trying to meet this need.
  • the relative movements with respect to a carrying carriage guided along the rails and serving as a reference base are detected by measurement sensors of a type assumed to be known, capable of delivering an output signal proportional to said movements of the probes.
  • the probes used in this case are not described in this patent, but are only illustrated in a purely schematic manner.
  • the present measuring device according to the invention tends to remedy this major drawback of existing devices and is distinguished by the characteristics listed in claim 1.
  • the device according to the invention offers the advantage of allowing the measurement, in the same plane perpendicular to the axis of the rails, of a sufficient number of generators to obtain a complete and faithful image of the running surface, of the leaves of the rail and of the upper part of the inner face of this rail.
  • this relatively simple mechanical solution has a small footprint so that even in work it does not encroach on the template of free obstacles and thus allows continuous measurement even in the switches.
  • two measuring devices 1, associated with each of the rows of rails 2, 2 'of a railway track are mounted using cylinders 3, 3' on a carriage comprising flanged wheels 4 resting on the rails.
  • This carriage formed of side members 5 and cross members 6 is connected to a rail vehicle for its movement along the railway track.
  • Each device is articulated on the carriage so as to be able to move laterally and vertically with respect thereto.
  • Each measuring device 1, 1 ′ comprises a guide frame formed by a guide dihedral 7 comprising a horizontal bearing face 8 intended to come into contact, in the service position, with the central area of the tread table 9 of the rail and a vertical support face 10 intended to come into contact, still in the service position, with the lower part of the internal lateral face 11 of the head 12 of the rail 2.
  • This dihedron 7 constitutes a reference base for measuring the profile of the rail and the bearing faces 8 and 10 can be assimilated to measuring probes and used for determining the transverse profile of the rail.
  • the bearing faces 8, 10 are preferably carried by shoes or pads 8a, 10a respectively, articulated along axes perpendicular to the longitudinal axis of the rail on the dihedron 7.
  • Each measuring device 1, 1 ' is also secured to a beam 13, 13' connected by means of a jack 14, 14 'to a support 15 secured to the carriage 5, 6.
  • each device measuring 1, 1 ' is applied vertically and laterally against the rail via the bearing faces 8, 10 of the frame 7 with a force determined by the action of the jacks 3, 3'; 14, 14 '.
  • the dihedral or frame 7 serves as a support for a set of mechanical probes 16, 16a ... 16th and 17a ... 17th each comprising a point contact member 20 intended to come into contact with the surface of the head 12 of the rail in a narrow area, transverse to rail 2, but preferably all located in the same plane normal to the longitudinal axis of the rail.
  • Each contact member 20, as well as the bearing faces 8, 10 rest in the service position, on a generator that differs from the head of the rail.
  • the number of probes 16, 17 is such, for example between 6 and 12. that it makes it possible to measure a number of generators sufficient to faithfully reconstruct the shape of this profile.
  • the ten feelers 16, 17 are distributed uniformly over the entire periphery of the rail head, that is to say its stable bearing and its internal and external leaves, as well as the upper part of the internal flank of the rail head.
  • Each mechanical probe 16, 17 is carried by two arms 18, respectively 19, pivoted on two axes 21, 21a respectively, integral with the frame 7 and extending parallel to the longitudinal axis of the rail 2 when the frame 7 is in the position of service guided by its pads 8, 10 on the rail.
  • the arms of the probes 16, 17 are nested one inside the other thus forming a very compact assembly, compact and allowing the positioning of all the point contact members 20 in the same plane normal to the longitudinal axis of the rail.
  • the probes are nested pair by pair, but in other examples not illustrated, the probes could be nested individually in each other.
  • Each probe is subjected to the action of at least one spring 22, tending to maintain its point contact member 20 in contact with the surface of the rail head.
  • These springs 22 are for example compression springs bearing on the one hand on a block 23 secured to the frame 7 and on the other hand on one of the arms 18, 19 of a probe.
  • each probe is integral with a control lever 24, respectively 25, extending vertically above the frame 7 and the upper end of these levers is provided with a ball roller 26.
  • Each lever 24, 25 is connected to the movable member 27 of a sensor 28 transforming the angular movements of these levers 24, 25 into electrical signals proportional to the movements of the feelers and which are therefore representative of the position of the contact point 20 of the feeler 16, 17 with the surface of the mushroom 12 of the rail 2.
  • the whole of this mechanical measuring device is very compact and can be housed inside the free obstacle gauge G of the track.
  • this purely mechanical measuring device it is possible to measure the exact profile, using 6 to 12 measuring points for example, of a cross section of the useful part of the head of the rail representing the tread and leave internal and external and the upper part of the internal side of the rail head.
  • 6 to 12 measuring points for example, of a cross section of the useful part of the head of the rail representing the tread and leave internal and external and the upper part of the internal side of the rail head.
  • the measuring device is located inside the freeway gauge G and can therefore be moved along the entire route of a railroad track.
  • the device illustrated is equipped with an automatic retraction system of the probes 16, 17 controlled by the presence of a counter rail 29.
  • This automatic retraction system comprises a control member 30, the lower part of which is intended to cooperate with a counter rail 29, articulated on a cross-member 6 of the carriage at 31 and secured to a lever 32 articulated on the beam 13.
  • this system also includes a second operating member 33 intended to cooperate with a counter rail associated with the other rail file, also pivoted, at 34, on the cross-member 6 of the carriage and secured to a lever 35 articulated on the beam 13 '.
  • one of the control members 30, 33 when, during the movement of the carriage along the railway track, one of the control members 30, 33 is moved under the effect of a counter rail, towards the outside of the track, it is that is to say in the direction of the rail 2, 2 ′ with which it is associated, it causes a relative displacement of the beams 13, 13 ′ with respect to each other causing a reduction in the distance separating the measuring devices 1, 1 'relating to each of the rows of rails 2, 2'.
  • Each control plate 45 is slidably mounted on the frame 7 of its measuring device using screws 46.
  • the lateral edges of this plate 45 include notches 47 in which are disposed, in the rest position of the plate 45, the rollers 26 of the levers 24, 25 of the feelers 16, 17.
  • control members 30, 33 causing the measurement device 1, 1 'to be raised by a cam 48 of these control members cooperating with a stop 49 carried by the measurement device.
  • the feelers are retracted and the measuring devices are raised automatically by the action of a counter rail on one of the control members 30, 33 during the movement of the carriage along the track.
  • Contact of one of the control members 30, 33 with the counter-rail 29 which is associated with it also prevents the measuring device from penetrating laterally into the gap in the switches.
  • the measuring device also includes a manual system for retracting the probes 17d and 17e coming into contact with the external flank of the rail.
  • These probes 17d and 17e must indeed be able to be raised selectively to allow the passage of the measuring device in work, the other probes remaining in contact with the rail, in level crossings for example.
  • This manual retraction system includes a second control plate 50 slidingly mounted on the frame 7 parallel to the first plate 45.
  • This plate 50 is subjected to the action of a return spring 51 and to a connecting rod 52 connected by a connection not illustrated to a manual control member.
  • One of the lateral edges of this plate 50 has notches 52, one of the sides of which cooperates with rollers 54 carried by the levers 24 of the probes 17d and 17e.
  • a displacement of this plate 50 enables the probes 17d and 17e to be selectively retracted as illustrated diagrammatically in FIG. 10.
  • this comprises two axes 21, 21a for pivoting the probes 16, 17 which are located symmetrically with respect to a vertical plane passing through the longitudinal axis of the rail 2.
  • these axes 21, 21a a can very well be arranged asymmetrically with respect to this plane.
  • the measuring device has a single axis 55, offset from the vertical plane passing through the longitudinal axis of the rail 2, around which all the probes 56a, 56b ... 56x are rotated. At least two of these feelers 56 are in contact with points on the surface of the rail head located on the other side of this vertical plane of the rail 2.
  • the measuring device generally comprises at least three feelers coming into contact with the tread of the rail and at least two feelers in contact with the internal leave and the internal upper side of the rail.
  • the device also comprises at least two feelers in contact with the external leave of the rail.
  • the articulated part or parts 8 forming the bearing surface of the dihedron 7 on the rail can simultaneously define a reference base for measuring the longitudinal undulations of the surface of the rail head.
  • the pads 8a articulated on the dihedral 7 are arranged on either side of the group of probes 16, 17 and this distance is sufficient to create the reference base of a measuring device as described for example in the European patent No. 0107833 (application No. 83110242.1).
  • this very compact measuring device can not only measure the transverse profile of a rail but also the longitudinal undulations, short or long, of its tread table.
