Description

La présente invention se rapporte à la mesure continue en voie de la forme du profil transversal de la portion utile du champignon d'un rail d'une voie ferrée. Par portion utile du champignon on entend celle servant d'appui aux roues de véhicules et notamment la surface de roulement, les congés et la partie supérieure de la face intérieure du rail.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. By useful portion of the mushroom 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.

Le développement des machines pour le reprofilage des rails en voie, par meulage ou rabotage, a fait apparaître la nécessité de connaître en tout temps et en tous points d'une voie la forme exacte du champignon des rails pour permettre le réglage précis de la position de travail des outils de reprofilage, (meules, blocs abrasifs, rabots, etc.) pour adapter cette position à l'état d'usure dudit champignon. Seule cette manière de faire permet de reconstituer parfaitement la forme désirée du champignon des rails sans recourir à un enlèvement superflu de matière, ainsi que de contrôler la qualité du travail effectué. <The development of machines for the reprofiling of track rails, by grinding or planing, has made it appear necessary to know at all times and in all points of a track the exact shape of the rail head to allow precise adjustment of the position. working of reshaping tools (grinding wheels, abrasive blocks, planes, etc.) to adapt this position to the state of wear of said mushroom. Only this way of making it possible to perfectly reconstitute the desired shape of the rail head without resorting to unnecessary removal of material, as well as to control the quality of the work carried out. <

C'est à ce besoin que tentait de répondre déjà le brevet CH 606.619 décrivant un dispositif de mesure comportant une série de palpeurs disposés côté à côte autour de la table de roulement, du congé et de la face intérieure du champignon des rails, palpeurs dont les mouvements relatifs par rapport à un chariot porteur guidé le long des rails et servant de base de référence, sont détectés par des capteurs de mesure d'un type supposé connu, propres à délivrer un signal de sortie proportionnel auxdits déplacements des palpeurs. Les palpeurs utilisés en l'occurence ne sont pas décrits dans ce brevet, mais sont seulement illustrés d'une façon purement schématique. En fait, les palpeurs connus à la date de publication du brevet précité avaient un encombrement très important, leur montage côte à côte dans un même plan transversal au rail présentait des difficultés telles qu'il n'était pas possible d'en disposer un nombre suffisant pour obtenir une mesure significative de la forme du champignon d'un rail.Patent CH 606.619, which describes a measuring device comprising a series of feelers arranged side by side around the running table, the fillet and the inner face of the rail head, has already attempted to meet this need. the relative movements with respect to a carrier trolley guided along the rails and serving as a reference base, are detected by measurement sensors of a supposedly known type, capable of delivering an output signal proportional to said displacements of the probes. The probes used in this case are not described in this patent, but are only illustrated in a purely schematic manner. In fact, the pal fears known at the date of publication of the aforementioned patent had a very large bulk, their mounting side by side in the same plane transverse to the rail presented difficulties such that it was not possible to have a sufficient number to obtain a significant measure of the shape of the rail head.

Le présent dispositif de mesure a&Lon l'invention tend à remédier à cet inconvénient majeur des dispositifs existantset se distingue par les caractéristiques énumérées dans la revendication 1.The present measurement device a & Lon the invention tends to remedy this major drawback of existing devices and is distinguished by the characteristics listed in claim 1.

Le dispositif selon l'invention offre l'avantage de permettre la mesure dans un même plan perpendiculaire à l'axe des rails d'un nombre suffisant de génératrices pour obtenir une image complète et fidèle de la surface..de roulement, des congés du rail et de la partie supérieure de la face intérieure de ce rail.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 rolling surface, of the leaves of the rail and the upper part of the inside of this rail.

En outre, cette solution mécanique relativement simple présente un faible encombrement de telle manière que même en travail elle n'empiète pas sur le gabarit d'obstacles libres et permet ainsi une mesure continue même dans les appareils de voie.In addition, 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.

Enfin, la possibilité de monter le même nombre de palpeurs symétriquement par rapport à l'axe des rails permet si on le désire de mesurer le congé extérieur et la partie supérieure de la face extérieure du rail. Dans cette exécution, les palpeurs supplémentaires nécessaires à cette mesure de la partie externe du rail sont escamotables indépendamment des autres palpeurs pour permettre d'éviter les obstacles qui peuvent se présenter dans la voie.Finally, the possibility of mounting the same number of sensors symmetrically with respect to the axis of the rails makes it possible, if desired, to measure the external leave and the upper part of the external face of the rail. In this embodiment, the additional feelers necessary for this measurement of the external part of the rail are retractable independently of the other feelers to allow obstacles which may arise in the track to be avoided.

  • Les figures 9 et 10 illustrent des variantes des ensembles de palpeurs mécaniques.Figures 9 and 10 illustrate variants of the sets of mechanical probes.

Dans l'exemple illustré, deux dispositifs de mesure 1, l'associés à chacune des files de rails 2, 2' d'une voie ferrée sont montés à l'aide de vérins 3, 3' sur un chariot comportant des roues à boudin 4 reposant sur les rails. Ce chariot formé de longerons 5 et de traverses 6 est relié à un véhicule ferroviaire pour son déplacement le long de la voie ferrée. Chaque dispositif est articulé sur le chariot de manière à pouvoir se déplacer latéralement et verticalement par rapport à celui-ci.In the example illustrated, two measuring devices 1, associated with each of the rows of rails 2, 2 'of a railway track are mounted using jacks 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.

Chaque dispositif de mesure 1, l' comporte un cadre de guidage formé par un dièdre de guidage 7 comportant une face d'appui horizontale 8 destinée à entrer en contact, en position de service, avec la zone centrale de la table de roulement 9 du rail et une face d'appui verticale 10 destinée à entrer en contact, toujours en position de service, avec la partie inférieure de la face latérale interne 11 du champignon 12 du rail.2.Ce dièdre 7 constitue une base de référence pour la mesure du profil du rail et les faces d'appui 8 et 10 peuvent être assimilés à des palpeurs de mesure et utilisés pour la détermination du profil transversal du rail. Les faces d'appui 8, 10 sont de préférence portées par des sabots ou patins 8a, 10a respectivement, articulés suivant des axes perpendiculaires à l'axe longitudinal du rail sur le dièdre 7.Each measuring device 1, l '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 zone of the tread table 9 of the rail and a vertical support face 10 intended to come into contact, always in the service position, with the lower part of the internal lateral face 11 of the head 12 of the rail. This dihedral 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.

Chaque dispositif de mesure 1, 1' est en outre solidaire d'une poutrelle 13, 13' reliée par l'intermédiaire d'un vérin 14, 14' à un support 15 solidaire du chariot 5, 6.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.

Ainsi, en position de service, chaque dispositif de mesure 1, l' est appliqué verticalement et latéralement contre le rail par l'intermédiaire des faces d'appui 8, 10 du cadre 7 avec une force déterminée par l'action des vérins 3, 3'; 14, 14'.Thus, in the service position, each measuring device 1, l 'is applied vertically and laterally against the rail by means of the bearing faces 8, 10 of the frame 7 with a force determined by the action of the jacks 3, 3 '; 14, 14 '.

Ainsi, chaque cadre ou dièdre 7, dont l'arête est, en position de service, parallèle à l'axe longitudinal du rail, constitue une base de référence, guidée avec précision par le rail 2 lui-même, pour la mesure du profil transversal du rail et son interprétation.Thus, each frame or dihedral 7, the edge of which is, in the service position, parallel to the longitudinal axis of the rail, constitutes a reference base, precisely guided by the rail 2 itself, for the measurement of the profile. rail cross-section and its interpretation.

Le dièdre ou cadre 7 sert de support à un ensemble de palpeurs mécaniques 16, 16a ...16e et 17a ... 17e comportant chacun un organe de contact porctuel 20 destiné à entrer en contact avec la surface du champignon 12 du rail dans une zone étroite, transversale par rapport au rail 2, mais de préférence situés tous dans un même plan normal à l'axe longitudinal du rail. Chaque organe de contact 20, de même que les faces d'appui 8, 10 reposent en position de service, sur une génératrice différente du champignon du rail. Le nombre de palpeurs 16, 17 est tel, par exemple compris entre 6 et 12, qu'il permette de mesurer un nombre de génératrices suffisant pour reconstituer fidèlement la forme de ce profil. Dans la forme d'exécution illustrée à la figure 1, les dix palpeurs 16, 17 sont répartis uniformément sur tout le pourtour du champignon du rail, soit sa table de roulement et ses congés internes et externes, ainsi que la partie supérieure du flanc interne du champignon du rail.The dihedral or frame 7 serves as a support for a set of mechanical probes 16, 16a ... 16th and 17a ... 17th each comprising a porctual 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 different generator of 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. In the embodiment illustrated in FIG. 1, the ten feelers 16, 17 are distributed uniformly over the entire periphery of the rail head, that is its tread table and its internal and external leaves, as well as the upper part of the internal flank of the rail head.

Chaque palpeur mécanique 16, 17 est porté par deux bras 18, respectivement 19, pivotés sur deux axes 21, 21a respectivement, solidaires du cadre 7 et s'étendant parallèlement à l'axe longitudinal du rail 2 lorsque le cadre 7 est en position de service guidé par ses patins 8, 10 sur le rail. Comme on le voit sur la figure 6, les bras des palpeurs 16, 17 sont imbriqués les uns dans les autres formant ainsi un ensemble très compact, peu encombrant et permettant le positionnement de tous les organes de contact ponctuels 20 dans un même plan normal à l'axe longitudinal du rail. Dans cet exemple, les palpeurs sont imbriqués paire par paire, mais dans d'autres exemples non illustrés, les palpeurs pourraient être imbriqués individuellement les uns dans les autres.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. As can be seen in FIG. 6, 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. In this example, the probes are nested pair by pair, but in other examples not illustrated, the probes could be nested individually in each other.

Chaque palpeur est soumis à l'action d'au moins un ressort 22, tendant à maintenir son organe de contact ponctuel 20 en contact avec la surface du champignon du rail. Ces ressorts 22 sont par exemple des ressorts de compression prenant appui d'une part sur un bloc 23 solidaire du cadre 7 et d'autre part sur l'un des bras 18, 19 d'un palpeur.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.

Les bras 18, 19 de chaque palpeur sont solidaires d'un levier de commande 24, respectivement 25, s'étendant verticalement au-dessus du cadre 7 et l'extrémité supérieure de ces leviers est munie d'un galet à bille 26. Chaque levier 24, 25 est relié à l'organe mobile 27 d'un capteur 28 transformant les déplacements angulaires de ces leviers 24, 25 en signaux électriques proportionnels aux déplacements des palpeurs et qui sont donc représentatifs de la position du point de contact 20 du palpeur 16, 17 avec la surface du champignon 12 du rail 2.The arms 18, 19 of each probe are 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 displacements res of these levers 24, 25 in electrical signals proportional to the displacements of the probes and which are therefore representative of the position of the point of contact 20 of the probe 16, 17 with the surface of the head 12 of the rail 2.

L'ensemble de ce dispositif de mesure mécanique est très compact et peut se loger à l'intérieur du gabarit d'obstacle libre G de la voie.The whole of this mechanical measuring device is very compact and can be housed inside the free obstacle gauge G of the track.

Grâce à ce dispositif de mesure purement mécanique on peut mesurer le profil exact, à l'aide de 6 à 12 points de mesure par exemple, d'une section transversale de la partie utile du champignon du rail représentant la table de roulement et les congés internes et extérieurs et la partie supérieure du flanc intérieur du champignon du rail. Dans l'exemple illustré on dispose de douze points de mesures situés sur des génératrices différentes du champignon du rail, dix palpeurs mécaniques 16, 17 et les deux surfaces d'appui 8, 10 du cadre 7.Thanks to this purely mechanical measuring device, the exact profile can be measured, 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 the leaves internal and external and the upper part of the internal side of the rail head. In the example illustrated, there are twelve measurement points located on different generatrices of the rail head, ten mechanical feelers 16, 17 and the two bearing surfaces 8, 10 of the frame 7.

Grâce à l'encombrement réduit du dispositif de mesure, celui-ci se trouve à l'intérieur du gabarit de voie libre G et peut donc être déplacé le long de tout le tracé d'une voie ferrée.Thanks to the reduced size of the measuring device, it is located inside the clear gauge G and can therefore be moved along the entire route of a railroad track.

Lorsque le dispositif doit être mis hors service pour un déplacement rapide du véhicule ou pour éviter des obstacles accidentels, il est relevé à l'aide des vérins 3, 3'.When the device must be taken out of service for rapid movement of the vehicle or to avoid accidental obstacles, it is raised using the cylinders 3, 3 '.

Pour permettre de franchir les lacunes des aiguillage sans encombres, le dispositif illustré est équipé d'un système d'escamottage automatique des palpeurs 16, 17 commandé par la présence d'un contre-rail 29.To make it possible to cross the gaps in the switches without problems, the device illustrated is equipped with an automatic retraction system for the probes 16, 17 controlled by the presence of a counter rail 29.

Ce système d'escamotage automatique comporte un organe de commande 30 dont la partie inférieure est destinée à coopérer avec un contre-rail 29, articulé sur une traverse 6 du chariot en 31 et solidaire d'un levier 32 articulé sur la poutrelle 13. D'une façon analogue, ce système comporte encore un second organe de manoeuvre 33 destiné à coopérer avec un contre-rail associé à l'autre file de rail, également pivoté,en 34, sur la traverse 6 du chariot et solidaire d'un levier 35 articulé sur la poutrelle 13'.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. D similarly, this system also includes a second member maneuver 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 '.

Ainsi lorsqu'au cours du déplacement du chariot le long de la voie ferrée, l'un des organes de commande 30, 33 est déplacé sous l'effet d'un contre-rail, vers l'extérieur de la voie, c'est-à-dire en direction du rail 2, 2' auquel il est associé, il provoque un déplacement relatif des poutrelles 13, 13' l'une par rapport à l'autre provoquant une diminution de la distance séparant les dispositifs de mesure 1, 1' afférent à chacune des files de rails 2, 2'.Thus 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'.

Lors de ce déplacement relatif des poutrelles 13, 13', parallèlement à leurs axes longitudinaux, une butée 36 fixée sur la poutrelle 13' et une butée 37 fixée sur la poutrelle 13 entrent en contact avec l'extrémité coudée 38, respectivement 39 d'un levier d'actionnement 40 respectivement 41, pivoté sur la poutrelle 13, respectivement 13'. Puis toujours au cours de ce déplacement relatif des poutrelles 13, 13', les leviers de commande 40, 41 sont entraînés en rotation.During this relative displacement of the beams 13, 13 ', parallel to their longitudinal axes, a stop 36 fixed on the beam 13' and a stop 37 fixed on the beam 13 come into contact with the bent end 38, respectively 39 d ' an actuating lever 40 respectively 41, pivoted on the beam 13, respectively 13 '. Then still during this relative movement of the beams 13, 13 ', the control levers 40, 41 are rotated.

L'extrémité des leviers 40, 41 soumise à l'action de ressorts de rappel 44, est reliée par des bielles 42, 43 à des plaques de commande 45 de chaque dispositif de mesure 1, 1'.The end of the levers 40, 41 subjected to the action of return springs 44, is connected by connecting rods 42, 43 to control plates 45 of each measuring device 1, 1 '.

Cnaque plaque de commande 45 est montée coulissante sur le cadre 7 de son dispositif de mesure à l'aide de vis 46. Les bords latéraux de cette plaque 45 comportent des échancrures 47 dans lesquelles sont disposés, en position de repos de la plaque 45, les galets 26 des leviers 24, 25 des palpeurs 16, 17.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.

Ainsi, lors d'une rotation des leviers de commande 40, 41, provoquée par un déplacement linéaire relatif des poutrelles 13, 13', les bords des échancrures 47 entrent en contact avec les galets 26 et provoquent 1 un pivotement des palpeurs autour des axes 21, 21a et ainsi un escamotage des palpeurs 16, 17 qui ne sont plus en contact avec le champignon 12 du rail 2.Thus, during a rotation of the control levers 40, 41, caused by a relative linear movement of the beams 13, 13 ', the edges of the notches 47 come into contact with the rollers 26 and cause 1 a pivoting of the feelers around the axes 21, 21a and thus a retraction of the feelers 16, 17 which are no longer in contact with the head 12 of the rail 2.

D'autre part, les organes de commande 30, 33 provoquent le soulèvement du dispositif de mesure 1, l' par une came 48 de ces organes de commande coopérant avec une butée 49 portée par le dispositif de mesure.On the other hand, the control members 30, 33 cause the measurement device 1 to be raised, the by a cam 48 of these control members cooperating with a stop 49 carried by the measurement device.

De cette manière, les palpeurs sont escamotés et les dispositifs de mesure sont relevés automatiquement par l'action d'un contre-rail sur l'un des organes de commande 30, 33 au cours du déplacement du chariot le long de la voie. Le contact d'un des organes de commande 30, 33 avec le contre-rail 29 qui lui est associé empêche également le dispositif de mesure de pénétrer latéralement dans la lacune des aiguillages.In this way, 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.

Dans la forme d'exécution illustrée, le dispositif de mesure comporte encore un système manuel d'escamotage des palpeurs 17d et 17e entrant en contact avec le flanc extérieur du rail. Ces palpeurs 17d et 17e doivent en effet pouvoir être relevés sélectivement pour permettre le passage du dispositif de mesure en travail, les autres palpeurs restant en contact avec le rail, dans des passages à niveaux par exemple. Ce système d'escamotage manuel comporte une seconde plaque de commande 50 montée coulissante sur le cadre 7 parallèlement à la première plaque 45. Cette plaque 50 est soumise à l'action d'un ressort de rappel 51 et à une bielle 52 reliée par une liaison non illustrée à un organe de commande manuel. L'un des bords latéraux de cette plaque 50 présente des entailles 52 dont l'un des côtés coopère avec des galets 54 portés par les leviers 24 des palpeurs 17d et 17e. Ainsi, un déplacement de cette plaque 50 permet d'escamoter sélectivement les palpeurs 17d et 17e comme illustré schématiquement à la figure 10.In the illustrated embodiment, the measuring device further comprises a manual retraction system sensors 17d and 17 e in contact with the outer sidewall of the rail. These probes 17d and 17e must in fact 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 comprises 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. Thus, a movement of this plate 50 enables the probes 17d and 17e to be selectively retracted as illustrated diagrammatically in FIG. 10.

On voit ainsi sur cette figure 10 que tout le dispositif de mesure est disposé à l'intérieur du gabarit de voie libre G, G' lorsque les deux palpeurs 17d et 17e sont escamotés, les autres palpeurs restant en contact avec le rail.It can thus be seen in this FIG. 10 that the entire measuring device is disposed inside the freeway gauge G, G 'when the two feelers 17d and 17e are retracted, the other feelers remaining in contact with the rail.

Dans le dispositif qui vient d'être décrit, celui-ci comporte deux axes 21, 21a de pivotement des palpeurs 16, 17 qui sont situés symétriquement par rapport à un plan vertical passant par l'axe longitudinal du rail 2. Ceci est un cas particulier, ces axes 21, 21a pouvant très bien être disposés dissymétriquement par rapport à ce plan.In the device which has just been described, 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. This is a case particular, these axes 21, 21a can very well be arranged asymmetrically with respect to this plane.

Dans la forme d'exécution illustrée schématiquement à la figure 9, le dispositif de mesure comporte un seul axe 55, décalé par rapport au plan vertical passant par l'axe longitudinal du rail 2, autour duquel T tous les palpeurs 56a, 56b ... 56x sont pivotés. Deux au moins de ces palpeurs 56 sont en contact avec des points de la surface du champignon du rail situé de l'autre côté de ce plan vertical du rail 2.In the embodiment illustrated schematically in Figure 9, the measuring device has a single axis 55, offset from the vertical plane passing through the longitudinal axis of the rail 2, around which T 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.

Le dispositif de mesure comporte généralement au moins trois palpeurs entrant en contact avec la table de roulement du rail et au moins deux palpeurs en contact avec le congé intérieur et le flanc supérieur interne du rail. De préférence ce dispositif comporte encore au moins deux palpeurs en contact avec le congé externe du rail.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. Preferably, this device also comprises at least two feelers in contact with the external leave of the rail.

Grâce à ce dispositif de mesure purement mécanique dont la conception originale permet le positionnement d'un grand nombre d'organes de contact du rail dans un même plan normal de l'axe de ce rail, le profil transversal d'un rail peut être mesuré avec grande précision. En effet 10 à 14 génératrices distinctes du champignon du rail peuvent être mesurées simultanément en voie sans problème. D'autre part du fait de son encombrement réduit, toute la voie peut être mesurée, le dispositif se logeant à l'intérieur du gabarit de voie libre. Enfin, grâce au dispositif d'escamotage automatique des palpeurs, ceux-ci ne tombent pas dans les lacunes des aiguillages.Thanks to this purely mechanical measuring device whose original design allows the positioning of a large number of rail contact members in the same normal plane of the axis of this rail, the transverse profile of a rail can be measured with great precision. Indeed 10 to 14 generators distinct from the rail head can be measured simultaneously on track without problem. On the other hand because of its reduced size, the whole track can be measured, the device being housed inside the clear track gauge. Finally, thanks to the automatic sensor retraction device, they do not fall into the gaps of the switches.

Il est à noter que le ou les parties articulées 8 formant la surface d'appui du dièdre 7 sur le rail peuvent simultanément définir une base de référence pour la mesure des ondulations longitudinales de la surface du champignon du rail. En effet, les patins 8a artïculés sur le dièdre 7 sont disposés de part et d'autre du groupe de palpeurs 16,17 et cette distance est suffisante pour créer la base de référence d'un dispositif de mesure tel que décrit par exemple dans le brevet européen No......(demande No.83110242.1). Ainsi, ce dispositif de mesure très compact peut non seulement mesurer le profil transversal d'un rail mais également les ondulations longitudinales, courtes ou longues, de sa table de roulement.It should be noted that 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. Indeed, the pads 8a articulated on the dihedron 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 ...... (application No.83110242.1). Thus, 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.
