Description

La présente invention a pour objet un dispositif de reprofilage et/ou de rectification en voie de la surface du champignon d'au moins un rail d'une voie ferrée.The subject of the present invention is a device for reprofiling and / or rectifying the surface of the head of at least one rail of a railroad track.

Sous l'effet des fortes charges et surtout des surcharges dynamiques, une usure ondulatoire se forme progressivement sur la surface du champignon du rail de même qu'une détérioration importante du profil de ce champignon, des bavures plus ou moins importantes peuvent se former.Under the effect of high loads and especially dynamic overloads, wave wear gradually forms on the surface of the rail head as well as a significant deterioration of the profile of this head, more or less significant burrs can form.

Pour permettre une utilisation de plus longue durée des rails on procède au reprofilage des rails notamment à leur rectification; opération qui a pour but de redonner au rail les profils transversaux et longitudinaux désirés.To allow longer use of the rails, the rails are reprofiled, in particular to their rectification; operation which aims to give the rail the desired transverse and longitudinal profiles.

Le reprofilage et la rectification des rails d'une voie de chemin de fer appelle de fréquents changements des outils de travail quelle que soit la nature de ceux-ci. Les outils en forme de fraises, ou de rabots, couteaux, burins sont soumis à des sollicitations et usures extrêmement élevées. Ils se rompent fréquemment. Les outils en forme de sabots abrasifs sont appliqués sur les rails avec une pression très élevée, ils subissent ainsi également des sollicitations pouvant amener leur rupture. D'autre part ils se déforment s'adaptant rapidement au profil de la surface à reprofiler au détriment du profil désiré.The reshaping and straightening of the rails of a railway track calls for frequent changes of work tools whatever their nature. Tools in the form of milling cutters, or planers, knives, chisels are subjected to extremely high loads and wear. They frequently break. The tools in the form of abrasive shoes are applied to the rails with very high pressure, they also undergo stresses which can lead to their rupture. On the other hand they deform quickly adapting to the profile of the surface to be reprofiled at the expense of the desired profile.

Les meules rotatives enfin sont souvent sollicitées d'une manière intensive du fait des puissances utilisées pour les faire tourner et de leur haute pression d'appui en vue d'un rendement maximum. Elles s'usent d'autre part très rapidement. D'où dans tous les cas la nécessité de changer relativement fréquemment les outils de reprofilage.Finally, rotary grinding wheels are often used intensively due to the powers used to rotate them and their high contact pressure for maximum efficiency. They also wear out very quickly. Hence in all cases the need to change the reprofiling tools relatively frequently.

On notera encore le besoin qu'il y a de remplacer en cours de travail un outil d'une forme ou d'un type particulier par un outil d'une autre forme ou d'un autre type en fonction de la nature du travail à effectuer.We will also note the need to replace during work a tool of a particular shape or type with a tool of another shape or another type depending on the nature of the work to be done. carry out.

C'est le cas en particulier avec les outils en forme de burins, couteaux ou avec les fraises qui ne peuvent traiter en une seule fois tout le profil du champignon du rail et qu'il faut remplacer par des couteaux ou des fraises munis d'un tranchant présentant une forme différente.This is the case in particular with tools in the form of chisels, knives or with milling cutters which cannot treat at once the entire profile of the rail head and which must be replaced by knives or milling cutters fitted with a cutting edge with a different shape.

Ces mêmes outils ne permettent du reste qu'un travail grossier de reprofilage et demandent à être remplacés par des outils d'un autre type, sabots abrasifs ou meules rotatives pour le travail de finition.These same tools only allow a coarse reprofiling work and require to be replaced by tools of another type, abrasive shoes or rotary grinding wheels for the finishing work.

Pour les meules rotatives, on relèvera l'intérêt qu'il y a à pouvoir utiliser des meules relativement dures dont l'usure est assez lente. Mais elles ne permettent alors, elles aussi, qu'un travail de dégrossissage et il est souhaitable de les remplacer par des meules plus tendres pour le travail de finition. Ces mêmes meules rotatives, plus particulièrement les meules lapidaires sont d'un diamètre tel qu'elles se prêtent mal au travail de reprofilage dans les aiguillages ou les passages à niveaux. Il est alors nécessaire de les remplacer par des meules lapidaires d'un plus petit diamètre ou par des meules périphériques.For rotary grinding wheels, we note the advantage of being able to use relatively hard grinding wheels whose wear is fairly slow. However, they also only allow roughing work and it is desirable to replace them with softer grinding wheels for the finishing work. These same rotary grinders, more particularly the lapidary grinders are of a diameter such that they do not lend themselves well to the work of reprofiling in switches or level crossings. It is then necessary to replace them with lapidary wheels of a smaller diameter or with peripheral wheels.

Toutes ces raisons entraînent la nécessité de changements fréquents des outils de travail. Mais de tels changements sont pratiquement impossibles en voie, quand bien même ils seraient autorisés au mépris des prescriptions de sécurité. Les différents systèmes de fixation rapide des outils de reprofilage qui ont été proposés ne changent rien à cet état des choses et l'on en arrive fréquemment à renoncer à un travail de finition qui serait pourtant souhaitable ou alors à interrompre le travail, sans profiter entièrement des intervalles déjà trop courts, disponibles entre les circulations de trains pour rentrer changer en gare les outils de reprofilage ou enfin à changer prématurément des outils de reprofilage présentant une certaine usure pour ne pas être obligé d'interrompre le travail en cours d'intervalles.All these reasons lead to the need for frequent changes of work tools. But such changes are practically impossible on the way, even if they would be authorized in disregard of safety regulations. The various quick fixing systems for reprofiling tools that have been proposed do not change this state of affairs and we often come to the point of giving up a finishing job which would be however desirable or else to interrupt work, without taking full advantage of the already too short intervals available between train movements to return to change the reprofiling tools at the station or finally to prematurely change reprofiling tools with some wear so as not to be forced to interrupt work during intervals.

La présente invention a pour but de remédier à ces inconvénients. Elle permet de remplacer rapidement voire automatiquement un outil de reprofilage par un autre identique ou de forme ou de types différents. Elle permet de faire toujours travailler l'outil le plus adapté au travail à exécuter ceci au profit de la qualité du travail.

Pour permettre de pallier les inconvénients cités dans l'introduction et de réaliser les buts que la titulaire s'est fixés, le dispositif de reprofilage selon la présente invention comporte au moins une unité de reprofilage tractée le long de la voie par un véhicule ferroviaire. Des moyens permettent de déplacer cette unité de reprofilage en hauteur par rapport au véhicule ainsi que d'appliquer au moins un outil de l'unité contre le rail avec une pression déterminée ou contre un organe de butée fixe ou réglable.To overcome the drawbacks mentioned in the introduction and achieve the goals that the holder has set, the reprofiling device according to the present invention comprises at least one reprofiling unit towed along the track by a rail vehicle. Means make it possible to move this reprofiling unit in height relative to the vehicle as well as to apply at least one tool of the unit against the rail with a determined pressure or against a fixed or adjustable stop member.

Chaque unité de reprofilage comporte un support déplaçable angulairement comportant une pluralité d'outils de reprofilage, formant un groupe d'outils, dont les faces ou arêtes de travail sont situées dans des plans différents. Par un déplacement angulaire du support par rapport au véhicule ferroviaire, chaque outil d'un même groupe d'outils peut être amené dans sa position de travail, lui permettant d'entrer en contact avec le rail pour le reprofiler, les autres outils de ce même groupe étant alors en position d'attente, ne pouvant pas coopérer avec le rail. Enfin, le dispositif de reprofilage selon l'invention comporte un dispositif de positionnement permettant de positionner le support de manière à amener en position de travail l'outil désiré, et un dispositif de blocage permettant de fixer le support dans la position désirée.Each reprofiling unit comprises an angularly displaceable support comprising a plurality of reprofiling tools, forming a group of tools, the working faces or edges of which are located in different planes. By an angular displacement of the support relative to the railway vehicle, each tool of the same group of tools can be brought into its working position, allowing it to come into contact with the rail to reprofile it, the other tools of this same group then being in the waiting position, unable to cooperate with the rail. Finally, the reprofiling device according to the invention comprises a positioning device making it possible to position the support so as to bring the desired tool into the working position, and a locking device making it possible to fix the support in the desired position.

Ainsi, chaque unité de reprofilage comporte plusieurs outils formant un groupe et pouvant être amenés par un déplacement angulaire du support successivement en position de travail, le déplacement du support pouvant être motorisé, et surtout sans devoir procéder à un changement d'outil. Les outils d'un même groupe peuvent être tous semblables s'il s'agit d'effectuer un même travail pendant une longue durée. Ces outils peuvent également être différents, adaptés chacun à un travail spécifique. C'est ainsi que dans un même groupe d'outils on peut avoir des meules lapidaires de diamètres différents, de granulométrie et de dureté différentes, des meules lapidaires et des meules périphériques, des rabots ou des sabots abrasifs; indifféremment.Thus, each reprofiling unit comprises several tools forming a group and which can be brought by an angular displacement of the support successively in the working position, the displacement of the support being able to be motorized, and above all without having to make a tool change. The tools of the same group can all be similar if it is a question of carrying out the same work for a long period. These tools can also be different, each adapted to a specific job. Thus, in the same group of tools, it is possible to have lapidary wheels of different diameters, of different particle size and hardness, lapidary wheels and peripheral wheels, planes or abrasive shoes; indifferently.

En déplaçant angulairement le support du groupe d'outils d'une unité de reprofilage d'un ou plusieurs pas, on remplace un outil par un autre, ce qui permet d'attein- dre les buts que la titulaire s'étaient fixés.By angularly moving the support of the tool group of a reprofiling unit by one or more steps, one tool is replaced by another, which makes it possible to achieve the goals that the holder had set for themselves.

La première forme d'exécution du dispositif de reprofilage illustrée aux figures 1 à 5 comporte un chariot de guidage 1, formé par un longeron 2 et des traverses 3, présentant des roues à boudins 4 roulant sur les rails 5,5' d'une voie ferrée. Ce chariot de guidage 1 est relié à un véhicule ferroviaire 6 d'une part par des vérins 7,8 pour permettre son relevage pour la marche haut le pied, et d'autre part par un timon 9 pour son entraînement le long de la voie.The first embodiment of the reprofiling device illustrated in FIGS. 1 to 5 comprises a guide carriage 1, formed by a beam 2 and cross members 3, having flanged wheels 4 rolling on the rails 5.5 ′ of a track. This guide carriage 1 is connected to a railway vehicle 6 on the one hand by jacks 7, 8 to allow it to be lifted for walking high, and on the other hand by a drawbar 9 for its drive along the track. .

Dans l'exemple illustré, ce chariot 1 présente des cadres 10 portés par chacune des extrémités des traverses 3, soit au total quatre cadres sur chacun desquels est montée une unité de reprofilage par l'intermédiaire de moyens permettant d'appliquer contre le rail les outils de l'unité, avec une force déterminée.In the example illustrated, this carriage 1 has frames 10 carried by each of the ends of the crosspieces 3, ie a total of four frames on each of which is mounted a reprofiling unit by means of means for applying against the rail the tools of the unit, with a determined force.

Chaque unité de reprofilage comporte un moteur électrique dont les deux extrémités de l'arbre moteur 11 sortent du carter 12 et sont adaptées à recevoir un outil de reprofilage, ici une meuleo Dans l'exemple illustré l'une des meules lapidaires 13 présente un plus petit diamètre que l'autre 14 pour permettre un reprofilage des aiguillages et des passages à niveaux, la meule 14 étant utilisée pour le reprofilage de la surface du champignon du rail 5 en pleine voie. Dans cette exécution, le carter 12 du moteur constitue un support angulairement déplaçable portant un groupe de deux outils 13,14. Ce support formé par le carter 12 du moteur d'entraînement des meules 13,14 en rotation comporte un flasque en forme de disque 15, situé dans un plan parallèle à l'arbre 11 du moteur, tourillonné dans un bloc 16 monté sur le cadre lO.Each reprofiling unit comprises an electric motor, the two ends of the motor shaft 11 of which come out of the casing 12 and are adapted to receive a tool. reprofiling, here a grinding wheel In the example illustrated one of the lapidary grinding wheels 13 has a smaller diameter than the other 14 to allow a reprofiling of switches and level crossings, the grinding wheel 14 being used for the reprofiling surface of the rail 5 head in full track. In this embodiment, the motor casing 12 constitutes an angularly displaceable support carrying a group of two tools 13,14. This support formed by the casing 12 of the motor for driving the grinding wheels 13,14 in rotation comprises a disc-shaped flange 15, located in a plane parallel to the shaft 11 of the motor, journalled in a block 16 mounted on the frame lO.

Comme on le voit à la figure 5, ce flasque 15 comporte sur sa périphérie quatre entailles a,b,c,d coopérant successivement avec un doigt de blocage l7 soumis à l'action d'un ressort 18 et pouvant être actionné manuellement à l'aide d'un organe de manoeuvre 19.As can be seen in FIG. 5, this flange 15 has on its periphery four notches a, b, c, d cooperating successively with a locking finger l7 subjected to the action of a spring 18 and capable of being actuated manually by the using an operating device 19.

Le bloc 16 est monté coulissant sur deux colonnes 20 solidaires du cadre 10. Le bloc 16 comporte des chambres 21 entourant les colonnes 20 qui elles comportent une partie de plus grand diamètre formant un piston 22. Des conduits 23,24 pratiqués dans les colonnes 20 permettent d'amener un fluide sous pression dans les chambres 21 soit d'un côté, soit de l'autre côté du piston 22 pour provoquer un déplacement du bloc 16 le long de ces colonnes. Ce système permet d'appliquer un des outils 13,14 de l'unité de reprofilage contre le rail avec une force déterminée.The block 16 is slidably mounted on two columns 20 integral with the frame 10. The block 16 includes chambers 21 surrounding the columns 20 which have a part of larger diameter forming a piston 22. Conduits 23, 24 made in the columns 20 allow to bring a pressurized fluid into the chambers 21 either on one side or on the other side of the piston 22 to cause a displacement of the block 16 along these columns. This system makes it possible to apply one of the tools 13, 14 of the reprofiling unit against the rail with a determined force.

Ainsi, avec un tel dispositif de reprofilage lorsque les conditions exigent le remplacement de l'outil 14 par l'outil 13, on procède aux opérations suivantes :

  • a. on relève l'unité de reprofilage à l'aide des vérins constitués par les chambres 21 du bloc 16 et le piston 22 et les colonnes 20 du cadre 10 pour que l'outil 14 ne soit plus en contact avec le rail.
  • b. On débloque à l'aide de l'organe de manoeuvre 19 le flasque 15.
  • c. On fait pivoter le support, ici constitué du flasque 15 et du carter 12 du moteur, de 180°. La figure 3 illustre le moteur et les meules pendant leur pivotement.
  • d. On vérouille le support dans cette nouvelle position à l'aide du doigt de blocage 17 entrant dans l'entaille b du flasque 15.
  • e. On applique la meule 13 contre le rail avec la force désirée à l'aide des vérins constitués par les chambres 21 et les colonnes 20,22.
Thus, with such a reprofiling device when the conditions require the replacement of the tool 14 by the tool 13, the following operations are carried out:
  • at. the reprofiling unit is raised using the jacks constituted by the chambers 21 of the block 16 and the piston 22 and the columns 20 of the frame 10 so that the tool 14 is no longer in contact with the rail.
  • b. The flange 15 is released using the operating member 19.
  • vs. The support is pivoted, here consisting of the flange 15 and the casing 12 of the engine, by 180 °. Figure 3 illustrates the motor and the grinding wheels during their pivoting.
  • d. The support is locked in this new position using the locking finger 17 entering the notch b of the flange 15.
  • e. The grinding wheel 13 is applied against the rail with the desired force using the jacks constituted by the chambers 21 and the columns 20, 22.

Il est évident que dans des variantes, le pivotement du support 12,15, et donc du moteur et des meules autour d'un axe parallèle à l'axe longitudinal du rail 5, peut être motorisé et commandé depuis l'intérieur du véhicule ferroviaire, de même que le blocage et le déblocage des positions angulaires du support. Ainsi, l'échange de l'outil de travail s'effectue rapidement et entièrement depuis l'intérieur du véhicule tracteur.It is obvious that in variants, the pivoting of the support 12,15, and therefore of the motor and the grinding wheels around an axis parallel to the longitudinal axis of the rail 5, can be motorized and controlled from inside the rail vehicle , as well as the blocking and unblocking of the angular positions of the support. Thus, the exchange of the working tool is carried out quickly and entirely from inside the towing vehicle.

Lorsque le véhicule ferroviaire est en gare au repos, il est possible de fixer le support 12,15 dans des positions angulaires intermédiaires grâce aux entailles c,d du flasque 15.When the railway vehicle is stationary at rest, it is possible to fix the support 12, 15 in intermediate angular positions thanks to the notches c, d of the flange 15.

Dans ces positions intermédiaires, l'axe des meules 13 respectivement 14 se trouvent à l'horizontale dans une position bien accessible facilitant leur remplacement.In these intermediate positions, the axis of the grinding wheels 13 respectively 14 are located horizontally in a well accessible position facilitating their replacement.

Dans une variante de cette forme d'exécution, les moteurs 12 associés à un même rail 5, respectivement 5' pourraient être reliés rigidement les uns aux autres, les deux moteurs ne formant alors qu'un support et une seule unité de reprofilage comportant deux groupes de deux outils. Cette solution présente l'avantage de ne pas avoir des groupes d'outils supportés en porte-à-faux.In a variant of this embodiment, the motors 12 associated with the same rail 5, respectively 5 ′ could be rigidly connected to each other, the two motors then forming only one support and a single reprofiling unit comprising two groups of two tools. This solution has the advantage of not having groups of tools supported in overhang.

Une seconde forme d'exécution du dispositif de reprofilage est illustrée aux figures 6 et 7. Ici également l'unité de reprofilage est montée sur un chariot 30, formé d'un longeron 31 et de traverses 32, roulant sur les rails 33 de la voie par des roues à boudins 34. Comme dans la première forme d'exécution décrite, sans que cela soit à nouveau représenté sur cette figure, ce chariot 30 est relié à un véhicule ferroviaire pour être tracté le long de la voie ainsi que par des moyens permettant un déplacement en hauteur de ce chariot par rapport au véhicule pour mettre hors service le dispositif de reprofilage lors des déplacements haut le pied du véhicule ferroviaire.A second embodiment of the reprofiling device is illustrated in FIGS. 6 and 7. Here also the reprofiling unit is mounted on a carriage 30, formed of a beam 31 and of cross members 32, rolling on the rails 33 of the track by flanged wheels 34. As in the first embodiment described, without this being shown again in this figure, this carriage 30 is connected to a railway vehicle to be towed along the track as well as by means allowing a displacement in height of this carriage with respect to the vehicle in order to deactivate the reprofiling device during movements at the top of the rail vehicle.

Ici l'unité de reprofilage comporte également un moteur 35 dont le carter présente deux oreilles 36,37 chacune reliée au longeron 31 par une bielle 38,39 articulée formant ainsi un parallélogramme déformable. Un vérin 40 est disposé entre une patte 41 solidaire du longeron 31 et un point intermédiaire de la bielle 38 et permet ainsi de provoquer des déplacements en hauteur, parallèlement à lui-même du moteur 35 ce qui comme on le verra permet d'appliquer un outil contre le rail avec une force déterminée ou de le rétracter.Here the reprofiling unit also includes a motor 35, the casing of which has two ears 36, 37 each connected to the spar 31 by an articulated rod 38, 39 thus forming a deformable parallelogram. A jack 40 is disposed between a lug 41 integral with the spar 31 and an intermediate point of the connecting rod 38 and thus makes it possible to cause displacements in height, parallel to itself of the engine 35 which which, as will be seen, makes it possible to apply a tool against the rail with a determined force or retract it.

Le carter de ce moteur 35 présente un flasque 42 du côté où l'arbre moteur 43 émerge. Cet arbre moteur 43 est tourillonné dans la paroi d'un boîtier 44, dont une face plane est appliquée contre la face libre du flasque 42, et se termine par un pignon conique 45.The casing of this motor 35 has a flange 42 on the side where the motor shaft 43 emerges. This drive shaft 43 is journalled in the wall of a housing 44, one flat face of which is applied against the free face of the flas than 42, and ends with a bevel gear 45.

La position angulaire du boîtier 44 par rapport au moteur est fixée à l'aide d'un doigt de blocage 52, soumis à l'action d'un ressort 53, coopérant avec des perçages borgnes 54 du boîtier 44. Un organe de manoeuvre 55 permet de libérer le doigt de blocage pour modifier la position angulaire du boîtier 44 par rapport au moteur. Dans cette forme d'exécution le boîtier 44 constitue le support déplaçable angulairement sur lequel est monté le groupe d'outils de reprofilage.The angular position of the housing 44 relative to the motor is fixed using a locking finger 52, subjected to the action of a spring 53, cooperating with blind holes 54 of the housing 44. An operating member 55 frees the locking finger to modify the angular position of the housing 44 relative to the motor. In this embodiment, the housing 44 constitutes the angularly displaceable support on which the group of reprofiling tools is mounted.

Ici également le groupe d'outils de reprofilage comporte deux meules lapidaires de diamètres différents 46,47 portées par des arbres 48,49 pivotés dans le boîtier 44. Les arbres 48,49 et l'arbre moteur 43 sont coplanaires. Chacun des arbres 48 et 49 comporte un pignon conique 50,51 en prise avec le pignon conique 45 de l'arbre moteur 43 pour l'entraînement en rotation des meules 46,470Here also the group of reshaping tools comprises two lapidary grinding wheels of different diameters 46,47 carried by shafts 48,49 pivoted in the housing 44. The shafts 48,49 and the motor shaft 43 are coplanar. Each of the shafts 48 and 49 has a bevel gear 50,51 in engagement with the bevel gear 45 of the motor shaft 43 for driving the grinding wheels in rotation 46,470

Dans cette exécution également seul un des outils d'un groupe d'outils de reprofilage est en position de travail à un moment donné et le passage d'un outil à partir de la position d'attente jusqu'en position de travail s'effectue par la rotation du boîtier 44 autour de l'arbre moteur 43. Des positions intermédiaires du support 44 peuvent également être prévues pour le remplacement d'une meule. Dans cette position intermédiaire l'axe d'un outil est alors situé approximativement horizontalement dans une position accessible et pratique pour son remplacement.In this execution also only one of the tools of a group of reshaping tools is in the working position at a given time and the passage of a tool from the standby position to the working position is carried out. by rotating the housing 44 around the motor shaft 43. Intermediate positions of the support 44 can also be provided for the replacement of a grinding wheel. In this intermediate position the axis of a tool is then located approximately horizontally in an accessible and practical position for its replacement.

Cette forme d'exécution présente l'avantage que le moteur 35 entraînant en rotation un groupe de meules 46,47 n'effectue par rapport au chariot 30 que des déplacements de translation de faibles amplitudes ce qui facilite son branchement électrique. Un autre avantage réside dans le fait que les engrenages 45,50,51 peuvent constituer si désiré un réducteur, la vitesse de rotation des meules 46,47 étant alors différente de celle de l'arbre moteur 43, voire différentes entre elles.This embodiment has the advantage that the motor 35 driving in rotation a group of grinding wheels 46, 47 only performs translational displacements with small amplitudes relative to the carriage 30, which facilitates its electrical connection. Another advantage lies in the fact that the gears 45, 50, 51 can constitute, if desired, a reduction gear, the speed of rotation of the wheels 46,47 then being different from that of the motor shaft 43, or even different from each other.

Dans cette exécution également on peut motoriser le blocage et le déblocage de la position angulaire du boîtier 44 ainsi que son entraînement en rotation autour de l'arbre moteur 43. Un autre avantage de cette exécution réside dans le fait que le support est plus léger ce qui en facilite l'entraînement en rotation.In this embodiment also, it is possible to motorize the blocking and unblocking of the angular position of the housing 44 as well as its drive in rotation around the motor shaft 43. Another advantage of this version resides in the fact that the support is lighter this which facilitates rotational training.

Les figures 8 et 9 illustrent une variante de cette forme d'exécution dans laquelle le groupe d'outils de reprofilage comporte quatre meules 56,57,58,59, chacune portée par un arbre tourillonné dans une paroi d'un boîtier 60 et engrenant par des pignons 61,62,63,64 avec le pignon 45 de l'arbre moteur 43. Le même système de blocage 52,53,54,55 est utilisé pour fixer les positions respectives du boîtier 60.FIGS. 8 and 9 illustrate a variant of this embodiment in which the group of reshaping tools comprises four grinding wheels 56, 57, 58, 59, each carried by a journaled shaft in a wall of a housing 60 and meshing by pinions 61,62,63,64 with the pinion 45 of the motor shaft 43. The same locking system 52,53,54,55 is used to fix the respective positions of the housing 60.

Dans une telle exécution, on peut prévoir deux meules lapidaires de grands diamètres 57,59, pour le reprofilage du champignon du rail, présentant des grains ou dureté différents la plus dure étant utilisée pour le travail de dégrossissage et la moins dure pour la finition. Il en va de même des meules lapidaires 56,58 de plus faible diamètre utilisées pour la rectification des aiguillages.In such an embodiment, two lapidary grinding wheels of large diameters 57.59 can be provided for the reprofiling of the rail head, having different grains or hardness, the harder being used for roughing work and the less hard for finishing. The same applies to the lapidary wheels 56, 58 of smaller diameter used for the rectification of the switches.

Dans la variante illustrée à la figure 10 le boîtier 65 constituant le support déplaçable angulairement autour de l'arbre moteur 43 porte deux outils rotatifs, une meule 66 entraînée en rotation par un axe 67 et un pignon 68 en prise avec le pignon moteur 45; et une fraise 69 entraînée en rotation par un axe 70 et un pignon 71 en prise également avec le pignon moteur 45. Ce boîtier porte encore deux outils fixes tels que des rabots 72, 73 ou sabots abrasifs. Dans cette variante, l'un des outils statiques 72 est prévu pour être en contact avec le rail 33 lors d'un déplacement du boîtier 65 par rapport à ce rail dans le sens de la flèche F tandis que l'autre outil statique 73 est prévu pour un déplacement relatif en sens inverseIn the variant illustrated in Figure 10 the housing 65 constituting the angularly movable support around the motor shaft 43 carries two rotary tools, a grinding wheel 66 rotated by an axis 67 and a pinion 68 in engagement with the motor pinion 45; and a milling cutter 69 driven in rotation by an axis 70 and a pinion 71 also engaged with the motor pinion 45. This housing also carries two stationary tools such as planes 72, 73 or abrasive shoes. In this variant, one of the static tools 72 is provided to be in contact with the rail 33 during a movement of the housing 65 relative to this rail in the direction of the arrow F while the other static tool 73 is provided for a relative movement in the opposite direction

On voit ainsi que les outils de reprofilage d'un même groupe peuvent être très différents les uns des autres et adaptés chacun à un travail particulier devant être effectué sur le rail.It is thus seen that the reprofiling tools of the same group can be very different from each other and each adapted to a particular job to be carried out on the rail.

Il est évident que le nombre d'outils de reprofilage porté par un même support n'est pas limité à quatre mais pourrait être supérieur. Grâce aux engrenages ou pignons entraînant les outils rotatifs, le rapport de réduction entre l'arbre de chaque outil et l'arbre moteur peut être adapté au type d'outils utilisés pour avoir une vitesse de rotation optimale de celui-ci.It is obvious that the number of reprofiling tools carried by the same support is not limited to four but could be greater. Thanks to the gears or pinions driving the rotary tools, the reduction ratio between the shaft of each tool and the motor shaft can be adapted to the type of tools used to have an optimal speed of rotation thereof.

En outre, chacun des arbres d'entraînement des outils rotatifs peut comporter un embrayage ou un accouplement à crabotspermettant d'entraîner relativement un ou plusieurs outils seulement.In addition, each of the drive shafts of the rotary tools may comprise a clutch or a clutch coupling allowing relatively one or more tools to be driven.

Dans la troisième forme d'exécution du dispositif de reprofilage illustrée à la figure 11, l'unité de reprofilage comporte un moteur 80 et deux supports déplaçables 81,82 portant chacun un groupe d'outils de reprofilage. Cette unité de reprofilage est directement reliée au véhicule ferroviaire 83 qui en assure le guidage le long du rail 84.In the third embodiment of the reprofiling device illustrated in FIG. 11, the reprofiling unit comprises a motor 80 and two movable supports 81, 82 each carrying a group of reprofiling tools. This reprofiling unit is directly connected to the rail vehicle 83 which guides it along the rail 84.

Dans cette exécution, le carter du moteur 80 est relié au véhicule ferroviaire 83 d'une part par un vérin 85 permettant de relever l'unité de reprofilage et simultanément d'en appliquer un outil de chaque groupe contre le rail 84 avec une force déterminée pour le travail. Le carter de ce moteur 80 est d'autre part relié au véhicule ferroviaire 83 par un timon 86 pour une traction le long de la voie.In this embodiment, the motor housing 80 is connected to the rail vehicle 83 on the one hand by a jack 85 making it possible to raise the reprofiling unit and simultaneously to apply a tool from each group against the rail 84 with a determined force for work. The casing of this motor 80 is on the other hand connected to the railway vehicle 83 by a drawbar 86 for traction along the track.

Le moteur 80 comporte des flasques 87,88 situés à ses extrémités, traversés par l'arbre moteur 89.

The ends of this motor shaft 89 are pivoted in the wall of housings 81,82 and end by pinions 90 respectively 91.

Des arbres 92,93 perpendiculaires à l'arbre moteur 89 sont pivotés dans les boîtiers 81 respectivement 82 et portent à leur extrémité émergeant desdits boîtiers deux meules lapidaires 94,95 et 96,97 de diamètres différents. Chaque arbre 92,93 porte une roue conique 98,99 en prise avec les pignons moteurs 90,91 respectivement.Shafts 92,93 perpendicular to the motor shaft 89 are pivoted in the housings 81 respectively 82 and carry at their end emerging from said housings two lapidary wheels 94,95 and 96,97 of different diameters. Each shaft 92.93 carries a bevel wheel 98.99 engaged with the driving pinions 90.91 respectively.

Comme dans la forme d'exécution précédente, chaque support 81, 82 est déplaçable angulairement par rapport au moteur 80 et donc par rapport au véhicule ferroviaire 83 autour de l'arbre moteur 89, une face plane de chaque boîtier 81,82 étant en appui contre le flasque 87 respectivement 88 dudit moteur 80.As in the previous embodiment, each support 81, 82 is angularly movable relative to the motor 80 and therefore relative to the rail vehicle 83 around the motor shaft 89, a flat face of each housing 81, 82 being supported against the flange 87 respectively 88 of said motor 80.

Dans cette exécution, chaque boîtier 81,82 comporte une denture circulaire 100,101 située dans un plan parallèle aux flasques 87,88. Un moteur 102,103 fixé sur le flasque 87 respectivement 88 entraîne un pignon 104, 105 en prise avec la denture 100, respectivement 101 pour l'entraînement en rotation et le positionnement des boîtiers 81, 82.In this embodiment, each housing 81.82 has a circular toothing 100.101 located in a plane parallel to the flanges 87.88.

Un doigt de blocage 106, 109 actionné par un électro-aimant 107,110 coopérant avec des trous borgnes 108,111 permet le blocage de la position angulaire des boîtiers 81,82 par rapport au moteur 80.A locking finger 106, 109 actuated by an electromagnet 107, 110 cooperating with blind holes 108, 111 allows the angular position of the housings 81, 82 to be locked relative to the motor 80.

Dans la quatrième forme d'exécution du dispositif de reprofilage (figures 12, 13) l'unité de reprofilage est montée sur un chariot 120 analogue au chariot 30 de la seconde forme d'exécution, roulant le long de la voie à l'aide de roues à boudins et tracté par un véhicule ferroviaire. Des moyens sont également prévus pour permettre des déplacements en hauteur de ce chariot par rapport au véhicule. Ces moyens sont de types bien connus et ne sont pas illustrés dans cette forme d'exécution.In the fourth embodiment of the reprofiling device (Figures 12, 13) the reprofiling unit is mounted on a carriage 120 similar to the carriage 30 of the second embodiment, rolling along the track using flanged wheels and towed by a railway vehicle. Means are also provided for allowing be displacements in height of this carriage relative to the vehicle. These means are of well known types and are not illustrated in this embodiment.

Le chassis de ce chariot 120 comporte deux glissières 121 transversales formées par des poutres en U dont les parties dorsales se font face. Un portique 122 est fixé à l'aide de goujons 123 sur ces glissières 121 dans une position telle qu'un outil de l'unité de reprofilage soit situé, lorsqu'il est en position de travail, au dessus du rail 124.The chassis of this carriage 120 comprises two transverse slides 121 formed by U-shaped beams whose dorsal parts face each other. A gantry 122 is fixed using studs 123 on these slides 121 in a position such that a tool of the reprofiling unit is located, when it is in the working position, above the rail 124.

L'unité de reprofilage comporte un moteur électrique 125 dont l'arbre d'entraînement 126 est tourillonné dans la paroi d'un boîtier 127 servant de support à un groupe d'outils de reprofilage.The reprofiling unit comprises an electric motor 125, the drive shaft 126 of which is journalled in the wall of a housing 127 serving to support a group of reprofiling tools.

Cette unité de reprofilage est reliée au portique 122 par un vérin dont le piston 128 est solidaire d'une tige 129 articulée en 130 sur le portique et dont le cylindre 131 est solidaire du carter du moteur 125. Le cylindre 131 coulisse dans une douille fendue 132 présentant une patte de fixation 133 fixée à l'aide d'un boulon 134 à la partie supérieure du portique 122. Une fente 135 de forme circulaire permet de modifier l'inclinaison du moteur 125 et par conséquent de la meule par rapport au rail 124.This reprofiling unit is connected to the gantry 122 by a jack whose piston 128 is integral with a rod 129 articulated at 130 on the gantry and whose cylinder 131 is integral with the motor casing 125. The cylinder 131 slides in a split socket 132 having a fixing lug 133 fixed with a bolt 134 to the upper part of the gantry 122. A slit 135 of circular shape makes it possible to modify the inclination of the motor 125 and consequently of the grinding wheel relative to the rail 124.

La partie frontale du moteur 125 d'où émerge l'arbre moteur 126 présente un flasque 136 portant un cliquet d'indexage 137 soumis à l'action d'un ressortThe front part of the motor 125 from which the motor shaft 126 emerges has a flange 136 carrying an indexing pawl 137 subjected to the action of a spring

138 dont le doigt 139 coopère avec des encoches 140 pratiquées à la périphérie d'un disque 141, parallèle au flasque 136, du support ou boîtier 127.138, the finger 139 of which cooperates with notches 140 formed on the periphery of a disc 141, parallel to the flange 136, of the support or housing 127.

L'extrémité de l'arbre moteur 126 porte un pignon d'entraînement 142 en prise avec deux autres pignons 143, 144 portés par des arbres d'entraînement 145,146 tourillonnés dans le boîtier 127, formant entre eux et avec l'arbre d'entraînement des angles de 120°o Chaque arbre d'entraînement 145,146 porte à son extrémité libre émergeant hors du boîtier un outil rotatif, ici des meules lapidaires 147,148.The end of the drive shaft 126 carries a drive pinion 142 in engagement with two other pinions 143, 144 carried by drive shafts 145,146 journalled in the housing 127, forming between them and with the drive shaft angles of 120 ° o Each drive shaft 145,146 carries at its free end emerging from the housing a rotary tool, here lapidary wheels 147,148.

Dans la position illustrée, l'axe de la meule 147 en position de travail est situé dans le plan longitudinal, vertical du rail 124 mais grâce à la fente 135 la meule 147 peut être inclinée autour de l'axe longitudinal du rail pour meuler des génératrices différentes de la surface du champignon du rail.In the illustrated position, the axis of the grinding wheel 147 in the working position is located in the longitudinal, vertical plane of the rail 124 but, thanks to the slot 135, the grinding wheel 147 can be inclined around the longitudinal axis of the rail for grinding generators different from the surface of the rail head.

Dans cette exécution, lorsqu'une meule 147 est en position de travail, l'autre meule 148 est dans une position d'attente inactive qui est simultanément une position dans laquelle son remplacement s'effectue aisé- mentoIn this embodiment, when a grinding wheel 147 is in the working position, the other grinding wheel 148 is in an inactive waiting position which is simultaneously a position in which its replacement is carried out easily.

Dans cet exemple, l'axe du moteur 125 est compris dans un plan perpendiculaire à l'axe longitudinal du rail mais dans une variante il pourrait être situé dans le plan vertical contenant l'axe longitudinal du rail 124. Dans cette variante, les glissières 121 seraient longitudinales et la position du rail illustrée en 124'.In this example, the axis of the motor 125 is included in a plane perpendicular to the longitudinal axis of the rail but in a variant it could be located in the vertical plane containing the longitudinal axis of the rail 124. In this variant, the slides 121 would be longitudinal and the position of the rail illustrated at 124 '.

Il est évident que l'entraînement en rotation du support 127 pour placer la meule 148 en position de travail et escamoter la meule 147 ainsi que l'actionnement du dispositif d'indexage 137, 138, 139 pour bloquer les positions de travail successives du boîtier peuvent être motorisés et commandés depuis l'intérieur du véhicule ferroviaire tractant le chariot 120.It is obvious that the drive in rotation of the support 127 to place the grinding wheel 148 in the working position and retract the grinding wheel 147 as well as the actuation of the indexing device 137, 138, 139 to block the successive working positions of the housing can be motorized and controlled from inside the rail vehicle towing the carriage 120.

Dans la cinquième forme d'exécution du dispositif de reprofilage illustrée aux figures 14 et 15 l'unité de reprofilage comportant un moteur 150 et un support déplaçable 151 portant un groupe d'outils de reprofilage est montée par l'intermédiaire d'un cadre 152 sur deux plaques 153 solidaires d'un chariot 154 guidé et tracté le long de la voie par un véhicule ferroviaire.In the fifth embodiment of the reprofiling device illustrated in FIGS. 14 and 15, the reprofiling unit comprising a motor 150 and a movable support 151 carrying a group of reprofiling tools is mounted by means of a frame 152 on two plates 153 secured to a carriage 154 guided and towed along the track by a rail vehicle.

Le cadre 152 est fixé par des boulons 155 traversant une fente 156 des plaques 153 et peut ainsi être incliné de manière à modifier l'orientation de l'outil en position de travail par rapport au rail 157.The frame 152 is fixed by bolts 155 passing through a slot 156 in the plates 153 and can thus be tilted so as to modify the orientation of the tool in the working position relative to the rail 157.

Ce cadre 152 comporte deux colonnes 158 présentant chacune un piston 159 situé dans une chambre 160 faisant partie du carter du moteur 150. Grâce aux vérins pneumatiques ou hydrauliques ainsi constitués, on a réalisé des moyens permettant d'appliquer un outil contre le rail avec une force déterminée; ces moyens permettent également de relever l'unité de reprofilage pour permettre le positionnement angulaire du support 151.This frame 152 comprises two columns 158 each having a piston 159 located in a chamber 160 forming part of the motor casing 150. Thanks to the pneumatic or hydraulic cylinders thus formed, means have been made allowing a tool to be applied against the rail with a determined force; these means also make it possible to raise the reprofiling unit to allow the angular positioning of the support 151.

Ici également le support 151 peut se déplacer angulairement autour de l'arbre 161 du moteur 150. Un électro-aimant 162, ou un vérin, actionnant un verrou 163 coopérant avec des trous borgnes 164 du support 151 permet un blocage des positions successives de travail du boîtier 151.Here also the support 151 can move angularly around the shaft 161 of the motor 150. An electromagnet 162, or a jack, actuating a lock 163 cooperating with blind holes 164 of the support 151 allows a blocking of the successive working positions of housing 151.

Dans cette forme d'exécution le groupe d'outils comporte une meule lapidaire 165 et une meule périphérique 166 montées sur des arbres 167,168 tourillonnés dans le boîtier 151 et entraînés par l'arbre moteur 161 par l'intermédiaire d'engrenages 169,170,171 et 172.In this embodiment, the group of tools comprises a lapidary wheel 165 and a peripheral wheel 166 mounted on shafts 167,168 journalled in the housing 151 and driven by the drive shaft 161 by means of gears 169,170,171 and 172.

Dans toutes les formes d'exécution décrites jusqu'ici tous les outils rotatifs portés par un support sont de préférence tous simultanément en rotation. Les outils rotatifs entraînés qui sont en position d'attente constituent alors un volant important permettant d'absorber les variations brusques de charge de l'outil en travail.In all the embodiments described so far, all the rotary tools carried by a support are preferably all simultaneously in rotation. The driven rotary tools which are in the standby position then constitute a large flywheel making it possible to absorb the sudden variations in the load of the tool in work.

La sixième forme d'exécution du dispositif de reprofilage illustrée aux figures 16 à 19 comprend un chariot 180 formé d'un longeron 181 et de traverses 182 et roulant sur les rails 183 de la voie par des roues à boudins 184. Ce chariot 180 est relié de façon connue, comme dans la première forme d'exécution décrite par exemple, à un véhicule ferroviaire par des moyens en assurant la traction le long de la voie et des moyens permettant de le déplacer en hauteur et éventuellement transversalement par rapport au véhicule ferroviaire.The sixth embodiment of the reprofiling device illustrated in FIGS. 16 to 19 comprises a carriage 180 formed of a spar 181 and cross members 182 and rolling on the rails 183 of the track by flanged wheels 184. This carriage 180 is connected in a known manner, as in the first embodiment described for example, to a railway vehicle by means ensuring traction along of the track and of the means making it possible to move it vertically and possibly transversely with respect to the railway vehicle.

Ce chariot 180 comporte pour chaque file de rails un coulisseau 185, monté coulissant dans des glissières 186 solidaires du chariot, pouvant se déplacer sensiblement perpendiculairement à l'axe longitudinal du rail. Des butées réglables 187 motorisées par des moteurs électriques 188 règlent la hauteur du coulisseau 185.This carriage 180 comprises for each row of rails a slide 185, mounted to slide in slides 186 secured to the carriage, capable of moving substantially perpendicular to the longitudinal axis of the rail. Adjustable stops 187 motorized by electric motors 188 regulate the height of the slide 185.

Ce coulisseau 185 porte un support déplaçable angulairement constitué par un plateau 189 situé dans un plan vertical parallèle à l'axe longitudinal du rail 183, comportant un moyeu 190 pivoté suivant un axe horizontal dans le coulisseau 185.This slider 185 carries an angularly displaceable support constituted by a plate 189 situated in a vertical plane parallel to the longitudinal axis of the rail 183, comprising a hub 190 pivoted along a horizontal axis in the slider 185.

Ce support rotatif 189,190 porte un groupe d'outils de reprofilage constitué par des burins de forme 191,192 et 193 fixés rigidement à la périphérie du plateau 189. La face de travail ou arête de coupe de ces rabots présente une forme correspondant à une partie du profil désiré pour le champignon du rail. Les burins 191 et 192 sont orientés de manière à coopérer avec le rail pour le reprofiler par rabotage lorsque le chariot se déplace dans le sens de la flèche H tandis que le burin 193 est orienté pour travailler sur le rail lorsque le chariot se déplace en sens inverse.This rotary support 189,190 carries a group of reshaping tools constituted by chisels of form 191,192 and 193 rigidly fixed to the periphery of the plate 189. The working face or cutting edge of these planes has a shape corresponding to a part of the profile desired for the rail head. The chisels 191 and 192 are oriented so as to cooperate with the rail to reprofile it by planing when the carriage moves in the direction of the arrow H while the chisel 193 is oriented to work on the rail when the carriage moves in the direction reverse.

La mise en place des outils en position de travail s'effectue à l'aide d'un dispositif de positionnement du support 189 comportant une chaîne 194 en prise avec une couronne dentée 195 solidaire de l'arbre 190 et entraînée par un pignon 196 solidaire de l'arbre d'un moteur 197 flasqué sur le support 1850The tools are put into working position using a support positioning device 189 comprising a chain 194 engaged with a toothed ring 195 secured to the shaft 190 and driven by a pinion 196 secured from the tree of a motor 197 flanged on support 1850

Un verrou 198 actionné par un vérin 199 coopère avec des entailles 200 de la périphérie du plateau 189 pour en fixer les positions de travail successives.A latch 198 actuated by a jack 199 cooperates with notches 200 on the periphery of the plate 189 to fix the successive working positions.

Dans une telle exécution la profondeur de coupe des burins 191, 192,193 est déterminée par les butées motorisées 188 définissant la position du coulisseau 185 et la force d'appui des burins sur le rail est donnée par le poids de ce coulisseau et des organes qu'il porte.In such an execution, the cutting depth of the chisels 191, 192, 193 is determined by the motorized stops 188 defining the position of the slider 185 and the bearing force of the chisels on the rail is given by the weight of this slider and of the members that he is wearing.

Toutes les formes d'exécution décrites, qu'elles utilisent des outils de reprofilage rotatifs ou non, permettent de substituer rapidement et facilement un outil en travail par un outil en attente pour tenir compte de son usure ou pour utiliser un outil particulièrement adapté à un genre de travail souhaité. Ainsi, les intervalles entre deux convois peuvent être utilisés au maximum pour le reprofilage des rails de la voie.All of the embodiments described, whether they use rotary reshaping tools or not, make it possible to quickly and easily replace a tool in work by a tool on standby to take account of its wear or to use a tool particularly suited to a kind of work desired. Thus, the intervals between two convoys can be used to the maximum for the reprofiling of the rails of the track.

Grâce au dispositif de reprofilage selon l'invention, il n'est pas nécessaire de sauter lors du travail de la voie les aiguillages ou les passages à niveaux, le meulage peut continuer, et toute la voie peut être reprofilée.Thanks to the reprofiling device according to the invention, it is not necessary to skip when working the track switches or level crossings, the grinding can continue, and the whole track can be reprofiled.
