Abstract

The surface re-shaper consists of two milling units equipped with height control cylinders (4,5,6,) and each comprising a frame (8,9), rollers (18) and a milling tool (24,24'), mounted beneath a railway vehicle (2). The two frames are articulated relative to one another about a pivot (20) with its axis perpendicular to the lengthwise axis of the rail, and they are of different lengths. The milling tools are mounted on supports (22,22') which can slide vertically relative to the frames, and connected to jacks (23) which control their positions relative to the rail. The re-shaper also has a rail heater situated in front of the milling tools, and a cooler behind them. A collector with a suction channel or magnet gathers the material removed from the rail surface during re-shaping.

Description

La présente invention concerne une installation de reprofilage des rails de chemin de fer travaillant en voie. Il existe de nombreux dispositifs permettant de reprofiler les rails d'une voie ferrée, ainsi que des véhicules ferroviaires équipés de ces dispositifs, en particulier ceux décrits dans les brevets CH 633.336; CH 654.047; CH 666.068 ou CH 675.440 qui comportent tous des unités de meulage permettant de corriger certains défauts des rails. Les rails en voie présentent non seulement des profils abímés mais encore des ondulations longitudinales dont les amplitudes varient. Le brevet CH 680.672 décrit un procédé permettant de programmer à l'avance de façon optimale les opérations de reprofilage à effectuer sur un tronçon donné. Grâce à ce procédé il est possible d'optimiser les opérations de maintenance dans le but de réduire le temps d'occupation des voies. Si l'on détermine grâce à ce procédé qu'il faut enlever beaucoup de matière pour corriger les défauts du rail, le meulage ou le polissage des rails peuvent nécessiter plusieurs passages sur le même tronçon, même en utilisant des machines à unités de meulage multiple. Ceci est difficilement compatible avec le temps pouvant être affecté aux travaux de reprofilage en fonction du taux d'occupation des voies ferrées. En utilisant des fraises plutôt que des meules, il est possible d'enlever plus de matière et donc de travailler plus rapidement. Le fraisage des rails en atelier est connu et décrit par exemple dans le brevet français 2.659.584. Pour obtenir un reprofilage précis, lors du fraisage ou du meulage en voie, il faut veiller à ce que la meule ou la fraise soit guidée longitudinalement et transversalement. De plus le résultat est influencé par la base de guidage qui porte l'outil. En effet, le point avant de cette base de guidage se déplace sur une surface présentant des défauts qui sont partiellement reproduits par l'outil. Des dispositifs de reprofilage de rail par fraisage en voie ont été proposés notamment dans le brevet AT 234.137 qui utilise comme base de guidage une longue règle qui supporte deux têtes de fraisage inclinées. Le brevet allemand DE 32 22 208 se sert de deux patins réglables en hauteur qui forment une base symétrique de part et d'autre de la fraise. Le brevet FR-2 405 329 utilise comme support pour des meules des cadres articulés les uns aux autres suivant des axes perpendiculaires à l'axe longitudinal de la voie. Ces cadres reposent sur le rail par des patins de longeurs identiques. Les bases de meulage peuvent être de differentes longueurs. Ces dispositifs présentent l'inconvénient de ne pouvoir corriger qu'un type de défaut du rail à la fois. Les ondulations longitudinales des rails n'ayant pas toutes la même longueur d'ondes, il convient d'éliminer à la fois des ondulations longues (30 cm à 3 mètres) et des ondulations courtes (3cm à 30 cm). Les dispositifs existants ont des outils portés par une base de guidage unique et ne corrigent donc que les ondulations d'une certaine longueur d'ondes (longues avec une base de guidage longue) ce qui n'est pas compatible avec la qualité requise pour les réseaux à haute vitesse.The present invention relates to an installation of reprofiling of railroad tracks working in way. There are many devices for reprofiling the rails of a railway track, as well as vehicles railways equipped with these devices, in particular those described in patents CH 633,336; CH 654.047; CH 666.068 or CH 675.440 which all include units of grinding to correct certain rail defects. Track rails not only have profiles damaged but still longitudinal undulations whose amplitudes vary. Patent CH 680,672 describes a process allowing optimal programming of the reprofiling operations to be carried out on a section given. Thanks to this process it is possible to optimize the maintenance operations in order to reduce time lane occupation. If we determine through this process that you have to remove a lot of material to correct rail defects, grinding or polishing the rails may require several passages on the same section, even when using machines with grinding units multiple. This is hardly compatible over time can be assigned to reprofiling work depending the occupation rate of railways. Using strawberries rather than millstones, it is possible to remove more material and therefore work faster. Rail milling in the workshop is known and described by example in French patent 2,659,584. To get a precise reprofiling, when milling or grinding in track, care must be taken that the grinding wheel or cutter is guided longitudinally and transversely. In addition the result is influenced by the guide base which carries the tool. Indeed, the front point of this guide base moves on a surface with defects which are partially reproduced by the tool. Devices rail reshaping by track milling have been proposed especially in patent AT 234,137 which uses as a basis guide a long ruler which supports two heads of inclined milling. German patent DE 32 22 208 is serves as two height-adjustable pads that form a symmetrical base on either side of the cutter. The patent FR-2 405 329 uses as support for grinding wheels frames hinged to each other along perpendicular axes to the longitudinal axis of the track. These frames rest on the rail by skates of identical lengths. The grinding bases can be of different lengths. These devices have the disadvantage of being able to correct only one type of defect of the rail at a time. The longitudinal undulations of not all rails have the same wavelength, both long ripples (30 cm to 3 meters) and short undulations (3cm to 30 cm). Existing devices have tools carried by a single guide base and therefore only correct undulations of a certain wavelength (long with a long guide base) which is not compatible with the quality required for high speed networks.

D'autre part la qualité du fini de fraisage est nettement insuffisante pour les trains à grande vitesse et il faut donc pour éliminer totalement les marques laissées par les dents de la fraise prévoir un polissage du rail, opération qui dans les dispositifs existants nécessite un passage ultérieur avec une autre machine.On the other hand, the quality of the milling finish is clearly insufficient for high speed trains and it therefore it is necessary to totally eliminate the marks left by the teeth of the cutter provide for a polishing of the rail, operation which in existing devices requires a subsequent passage with another machine.

Le but de la présente invention est d'obvier aux inconvénients cités précédemment. La titulaire propose à cet effet une installation de reprofilage d au moins un rail d'une voie ferrée capable d'enlever une grande quantité de métal et d'éliminer aussi bien les ondulations longues que les ondulations courtes, tout en assurant un fini parfait des rails reprofilés. Un autre but de l'invention est d'augmenter la vitesse du travail de reprofilage du rail. Il faut en outre que l'installation de reprofilage permette d'éliminer et de traiter les résidus de métal résultant du reprofilage en voie.The object of the present invention is to obviate the drawbacks cited above. The licensee proposes that effect a reprofiling installation of at least one rail a railway capable of removing a large amount of metal and eliminate both long ripples and short waves, while ensuring a perfect finish reprofiled rails. Another object of the invention is increase the speed of the rail reprofiling work. In addition, the reprofiling installation must allow to remove and treat the resulting metal residue reprofiling in progress.

Le wagon de fraisage et de stockage des copeaux illustré à la figure 1 constitue l'élément de tête de l'installation de reprofilage des rails. Ce wagon comporte, situé à l'avant du dispositif de fraisage, un dispositif de mesure 1 qui permet d'évaluer les déformations du rail à traiter. Le dispositif de fraisage est fixé au châssis 2 du véhicule ferroviaire 3 à l'aide de vérins 4,5,6 qui permettent de maintenir le dispositif de fraisage en position de travail et de le relever. Un timon 7 relie le châssis 2 au cadre 9 du dispositif de fraisage. Ce timon 7 permet l'entraínement le long de la voie du dispositif de fraisage. Le dispositif de fraisage comporte deux cadres 8,9 articulés entre eux. Ces cadres 8,9 reposent en trois points sur chaque rail par l'intermédiaire d'unités de support et de guidage 10,11,12 de longueurs différentes. Les cadres 8 et 9 ont une longueur différente, le cadre 8 portant l'unité de fraisage 13 étant plus long que le cadre 9 qui porte l'unité de fraisage 14. Ces cadres 8,9 constituent chacun une base de guidage pour l'unité de fraisage 13,14 qu'ils portent. L'unité de fraisage 13 portée par le cadre 8 le plus long permettra d'éliminer les ondulations longues du rail, alors que l'unité de fraisage 14 portée par le cadre 9 éliminera les ondulations courtes.The shaving milling and storage wagon illustrated in Figure 1 is the top element of the installation rail reprofiling. This wagon features, located at the front of the milling device, a device of measurement 1 which makes it possible to evaluate the deformations of the rail treat. The milling device is fixed to the chassis 2 of the rail vehicle 3 using cylinders 4,5,6 which keep the milling device in position work and take it up. A drawbar 7 connects the frame 2 to frame 9 of the milling device. This drawbar 7 allows training along the path of the device milling. The milling device has two frames 8.9 articulated between them. These 8.9 frames rest in three points on each rail through units of support and guide 10,11,12 of different lengths. Frames 8 and 9 have a different length, frame 8 bearing the milling unit 13 being longer than the frame 9 which carries the milling unit 14. These frames 8.9 each constitute a guiding base for the unit of milling 13,14 they carry. Milling unit 13 mounted by the longest frame 8 will eliminate the long undulations of the rail, while the milling unit 14 carried by the frame 9 will eliminate the ripples short.

Chacune des unités de fraisage 13,14 est munie d'une fraise ainsi que des moyens de déplacement de cette fraise qui seront décrits en détail ci-dessous. De plus, chaque unité de fraisage est pivotéè sur son support autour d'un axe horizontal, par exemple comme décrit en référence aux figures 4 et 5. La figure 1 illustre encore des dispositifs de chauffage du rail 15,16 situés à l'avant de chacune des deux unités de fraisage 13,14 ainsi qu'un dispositif de refroidissement du rail 17 situé à l'arrière du dispositif de fraisage. Les dispositifs de chauffage du rail sont montés sur les cadres 8,9 respectivement. L'unité de refroidissement 17 est tractée par le second cadre 9 à l'aide d'un timon.Each of the milling units 13,14 is provided with a cutter as well as means for moving this cutter which will be described in detail below. In addition, each milling unit is pivoted on its support around a horizontal axis, for example as described with reference to Figures 4 and 5. Figure 1 further illustrates devices rail heating 15,16 located at the front of each two milling units 13,14 as well as a device cooling of the rail 17 located at the rear of the milling device. Heating devices from rail are mounted on the frames 8.9 respectively. Unity cooling 17 is towed by the second frame 9 using a drawbar.

L'unité de mesure 1 des déformations du rail permet de déterminer la profondeur de coupe à laquelle on désire faire travailler les fraises, ainsi que la puissance à fournir aux unités de chauffage pour une vitesse d'avancement donnée. The measurement unit 1 of the rail deformations allows determine the depth of cut you want work the strawberries, as well as the power to provide heating units for forward speed given.

La figure 2 illustre schématiquement et plus en détail une forme d'exécution du dispositif de fraisage. Ce dispositif comporte un premier cadre 8 relié par l'intermédiaire de deux vérins 4,5 au châssis 2 du véhicule. Ces vérins 4,5 maintiennent le cadre 8 sous le châssis 2 et permettent de le relever lors de la marche haut le pied par exemple. En fonctionnement, ces vérins 4,5 permettent d'appliquer l'unité de fraisage contre le rail avec une force déterminée.Figure 2 illustrates schematically and in more detail an embodiment of the milling device. This device comprises a first frame 8 connected via two cylinders 4,5 to chassis 2 of the vehicle. These 4.5 cylinders hold the frame 8 under the frame 2 and allow to raise it when walking high foot for example. In operation, these cylinders 4.5 allow press the milling unit against the rail with a determined force.

Le cadre 8 vu de coté comporte une partie horizontale s'étendant approximativement entre les deux vérins 4 et 5. Cette partie horizontale se prolonge par un montant oblique vers l'avant et vertical à l'arrière. Le montant oblique est relié à un premier dispositif d'appui et de guidage 10. Ce dispositif 10 est muni de roulettes 18 qui sont en contact avec le rail en position de travail et de patins de guidage 19. Un deuxième dispositif d'appui et de guidage 11 sert de support au montant arrière du cadre 8. Le dispositif de fraisage comporte encore un second cadre 9 portant une seconde unité de fraisage. Le montant avant oblique du deuxième cadre 9 est articulé sur le montant arrière du cadre 8 au moyen d'un axe 20 perpendiculaire à l'axe longitudinal du rail. Le montant arrière du cadre 9 repose sur un dispositif d'appui et de guidage 12 également muni de roulettes et de patins de guidage. Les deux cadres 8,9 articulés entre eux reposent en trois points sur les rails.The frame 8 seen from the side has a horizontal part extending approximately between the two cylinders 4 and 5. This horizontal part is extended by an amount oblique towards the front and vertical at the back. The amount oblique is connected to a first support device and guide 10. This device 10 is provided with rollers 18 which are in contact with the rail in the working position and guide shoes 19. A second support and guide 11 serves as a support for the rear upright of the frame 8. The milling device also has a second frame 9 carrying a second milling unit. The amount before oblique of the second frame 9 is articulated on the upright rear of frame 8 by means of an axis 20 perpendicular to the longitudinal axis of the rail. The rear upright of the frame 9 rests on a support and guide device 12 also fitted with castors and guide shoes. Both 8.9 hinged frames rest at three points on rails.

Deux colonnes de guidage 21,21' solidaires de la partie horizontale du cadre 8 s'étendent perpendiculairement à cette dernière en direction du rail. Un support 22 muni de deux alésages correspondant aux colonnes de guidage 21,21' est relié par l'intermédiaire d'une vis 23 au cadre 8. Ce support 22 comporte une fraise 24 ainsi que le moteur servant à son entraínement.Two guide columns 21,21 'integral with the part frame 8 extend perpendicularly to the latter towards the rail. A support 22 provided two bores corresponding to the guide columns 21.21 'is connected via a screw 23 to the frame 8. This support 22 includes a cutter 24 as well as the motor used for his training.

Grâce au dispositif de commande 25 de la vis 23, il est possible de faire varier la distance entre le support 22 et le rail, et de ce fait de régler la profondeur de coupe de la fraise 24. Une deuxième unité de fraisage est agencée de la même façon sous le cadre 9.Thanks to the control device 25 of the screw 23, it is possible to vary the distance between the support 22 and the rail, and thereby adjust the depth of cutter cutter 24. A second milling unit is arranged in the same way under the frame 9.

La figure 3 qui est une vue en bout du dispositif de fraisage montre le dispositif qui permet de régler l'écartement des cadres 8,9 associés à chaque rail. Un vérin hydraulique 26 couplé à un dispositif de guidage 27 permet de plaquer les patins de guidage 19 contre le flanc intérieur de chaque rail. Ces patins 19 peuvent être remplacés par des galets de guidage prenant appui contre le flanc intérieur du rail. Le dispositif de guidage est encore muni d'une roulette de guidage 28 qui est appliquée sous l'action d'un vérin 29 contre le flanc extérieur du rail assurant de ce fait un guidage transversal parfait. Les dispositifs d'appui et de guidage 10,11,12 comportent plusieurs roulettes 18 et patins 19. Les roulettes 18 peuvent dans une variante être remplacées par des patins d'appui. Ces roulettes 18 et leurs patins 19 peuvent être espacés les uns des autres d'une valeur fixe ou selon une fonction déterminée. En définissant un espacement irrégulier entre les roulettes 18, par exemple un espacement correspondant aux nombres premiers, on évite qu'en présence d'ondulations régulières du rail, les roulettes reposent toutes sur un maximum ou un minimum de l'amplitude de l'ondulation du rail. Grâce aux dispositifs d'appui et de guidage 10,11,12 ainsi qu'aux vérins d'écartement 26 on assure un positionnement parfait des cadres 8,9 par rapport au rail. Ce guidage transversal du dispositif de fraisage permet d'obtenir une grande précision lors du fraisage. Les cadres 8 et 9 ont des longueurs différentes et servent de base de guidage aux fraises 24,24'. La base de guidage de la première fraise, formée par le cadre 8 et les dispositifs d'appui 10,11, est plus longue que la base de guidage 9,11,12 de la seconde fraise 24'. Ainsi la première fraise va pouvoir corriger les ondulations les plus longues alors que la deuxième fraise 24' portée et guidée par une base 9 plus courte corrige les ondulations plus courtes. La distance entre les deux fraises est déterminée pour assurer la meilleure fonction de transfert de l'ensemble, c'est-à-dire la meilleure correction des ondulations longues et courtes du rail. On obtient ainsi non seulement une très forte diminution de l'amplitude des défauts, mais aussi une excellente qualité de surface grâce au fait que la deuxième fraise 24' travaille à une profondeur de coupe pratiquement constante, les défauts importants ayant été éliminés par la première fraise 24.Figure 3 which is an end view of the device milling shows the device for adjusting the spacing 8.9 frames associated with each rail. A hydraulic cylinder 26 coupled to a guide device 27 allows to press the guide pads 19 against the inner flank of each rail. These pads 19 can be replaced by guide rollers bearing against the side inside the rail. The guide device is still provided with a guide roller 28 which is applied under the action of a jack 29 against the outer flank of the rail thereby ensuring perfect transverse guidance. The support and guiding devices 10,11,12 comprise several 18 wheels and skates 19. The 18 wheels can in a variant be replaced by support pads. These rollers 18 and their pads 19 can be spaced each other of a fixed value or according to a function determined. By defining an irregular spacing between the rollers 18, for example a corresponding spacing with prime numbers, we avoid that in the presence of ripples regular rail, the casters all rest on a maximum or a minimum of the amplitude of the ripple of the rail. With support and guiding devices 10,11,12 as well as with the spacers 26 a perfect positioning of the frames 8.9 relative to the rail. This transverse guidance of the milling device allows obtain high precision during milling. The frames 8 and 9 have different lengths and serve as 24.24 'strawberry guide base. The guiding base of the first cutter, formed by the frame 8 and the devices support 10,11, is longer than the guide base 9,11,12 of the second 24 'cutter. So the first strawberry will be able to correct the longest ripples then that the second cutter 24 'carried and guided by a base 9 shorter corrects shorter ripples. The distance between the two strawberries is determined to ensure the best transfer function of the whole, i.e. the best correction for long ripples and short of the rail. We thus obtain not only a very sharp decrease in the amplitude of the defects, but also excellent surface quality thanks to the fact that the second 24 'cutter works at a cutting depth practically constant, the significant defects having been eliminated by the first cutter 24.

La figure 2 illustre encore schématiquement une unité de chauffage 31 montée sur le châssis 22. Cette unité de chauffage 31 permet d'amener la pellicule superficielle du champignon du rail à une température de l'ordre de quelques centaines de degrés, ce qui facilite grandement le travail des fraises 24,24'. La température de travail est adaptée à chaque type d'acier des rails. Le chauffage est généralement réalisé grâce à un dispositif de chauffage par induction HF, mais on peut également envisager un dispositif de chauffage par laser ou tout autre dispositif permettant d'amener rapidement la couche superficielle du rail à une température élevée. Une deuxième unité de chauffage (non illustrée) peut être agencée sur le support 22' de la deuxième fraise 24'. Le chauffage du rail permet d'une part d'augmenter la productivité (vitesse d'avancement et enlèvement de matière) du fraisage d'un facteur de l'ordre de 5 et d'autre part l'usure des fraises est réduite d'un facteur du même ordre de grandeur. Associées à chaque unité de fraisage, on trouve les entrées 32,32' d'un dispositif d'aspiration qui permet de récupérer les copeaux produits par les fraises. Le dispositif d'aspiration et de stockage des copeaux est décrit en référence à la figure 13.Figure 2 again schematically illustrates a unit heater 31 mounted on chassis 22. This unit heating 31 makes it possible to bring the surface film of the rail head at a temperature of around a few hundred degrees, which greatly facilitates the work of strawberries 24.24 '. Working temperature is suitable for each type of rail steel. Heating is usually achieved through a heater by HF induction, but we can also consider a laser heater or other device allowing to quickly bring the surface layer of the rail at a high temperature. A second unit of heating (not shown) can be arranged on the support 22 'from the second cutter 24'. Rail heating allows on the one hand to increase productivity (speed of advancement and material removal) from milling by a factor of the order of 5 and on the other hand the wear of the cutters is reduced by a factor of the same order of magnitude. Associated with each milling unit, there are 32,32 'inputs a suction device that collects the chips produced by strawberries. The suction device and chip storage is described with reference to Figure 13.

Les figures 4,5 illustrent en détail une deuxième forme d'exécution des unités de fraisage ainsi que leur mode de fixation sur le cadre qui leur sert de base de guidage. L'unité de fraisage comporte une fraise 40 montée sur un mandrin 41. Cette fraise 40 est entraínée en rotation par un moteur 42 couplé à un entraínement 43 qui peut être muni d'un réducteur de vitesse ou d'un embrayage. Cet ensemble est monté sur un support 44 par l'intermédiaire d'un élément de liaison 45. Cet élément de liaison 45 est monté pivotant sur le support 44 selon un axe contenu dans un plan vertical passant par un axe parallèle à l'axe longitudinal du rail. Des moyens (non illustrés) sont agencés dans le support 44 permettant de faire varier la position angulaire de l'élément de liaison 45 par rapport au support 44 sous l'action d'un organe de commande. Ainsi l'unité de fraisage peut effectuer une rotation de 90 degrés, ce qui permet d'amener successivement la fraise d'une position de travail sur le rail (figure 4) à une position de changement des outils comme illustré à la figure 5. Le cadre 8 qui sert de base de guidage à l'unité de fraisage comporte une pièce 46 munie d'une butée mécanique 47. Le support 44 est monté pivotant sur la pièce 46 autour d'un axe 48. En actionnant un vérin 49 dont la tige est solidaire du support 44, et dont le cylindre est fixé à la pièce 46, il est possible de déplacer la fraise 40 dans le plan vertical perpendiculairement aux rails. Ceci permet d'amener la fraise plus ou moins près du rail en fonction de la profondeur de coupe désirée pour le reprofilage. L'unité de fraisage en position relevée est indiquée en pointillés à la figure 4.Figures 4,5 illustrate in detail a second form of execution of the milling units and their method of attachment to the frame which serves as their basis for guidance. The milling unit has a 40 cutter mounted on a mandrel 41. This milling cutter 40 is rotated by a motor 42 coupled to a drive 43 which can have a speed reducer or a clutch. This assembly is mounted on a support 44 via of a connecting element 45. This connecting element 45 is pivotally mounted on the support 44 along an axis contained in a vertical plane passing through an axis parallel to the longitudinal axis of the rail. Means (not shown) are arranged in the support 44 allowing the position to be varied angle of the connecting element 45 relative to the support 44 under the action of a control member. So unity milling machine can rotate 90 degrees, which allows to successively bring the cutter from a position working on the rail (figure 4) at a position change of tools as illustrated in figure 5. The frame 8 which serves as a guide base for the milling unit comprises a part 46 provided with a mechanical stop 47. The support 44 is pivotally mounted on part 46 around a axis 48. By actuating a jack 49 whose rod is integral of the support 44, and the cylinder of which is fixed to the piece 46, it is possible to move the cutter 40 in the vertical plane perpendicular to the rails. this allows to bring the cutter more or less close to the rail in function the desired depth of cut for reprofiling. The milling unit in the raised position is indicated in dotted in Figure 4.

La figure 6 illustre le dispositif de fraisage vu de dessus qui comporte quatre unités de fraisage agencées dans leurs cadres respectifs 8,9,8',9'. Les vérins d'écartement 26 permettent de régler l'écartement entre les dispositifs d'appui et de guidage 10,10',11,11',12,12 sur lesquels reposent les cadres 8,9,8',9' qui portent les unités de fraisage.Figure 6 illustrates the milling device seen from above which has four milling units arranged in their respective frames 8,9,8 ', 9'. The spacers 26 allow to adjust the spacing between the devices support and guide 10,10 ', 11,11', 12,12 on which rest the frames 8,9,8 ', 9' which carry the milling units.

Le wagon de fraisage et de stockage des copeaux illustré en coupe longitudinale à la figure 7 montre le dispositif qui permet le changement de l'outil depuis l'intérieur du wagon. Un chariot 50 portant un palan 51 peut se déplacer longitudinalement le long d'un rail 52 fixé au plafond du wagon et venir charger une fraise située dans la partie avant du wagon qui constitue le stock de fraises. La fraise est amenée grâce au palan 51 à travers une ouverture 53 pratiquée dans le plancher du wagon, au dessus de l'unité de fraisage sur laquelle on désire effectuer un changement d'outil.The shaving milling and storage wagon illustrated in longitudinal section in Figure 7 shows the device which allows the tool to be changed from the inside from the wagon. A carriage 50 carrying a hoist 51 can be move longitudinally along a rail 52 fixed to the ceiling of the wagon and come and load a cutter located in the front part of the wagon which constitutes the stock of strawberries. The cutter is brought through the hoist 51 through an opening 53 made in the floor of the wagon, at above the milling unit on which you wish to perform a tool change.

La figure 8 montre dans une autre vue le principe de changement des fraises. L'unité de fraisage 55 située sur la gauche de la figure est en position de service en train de fraiser le rail, alors que l'unité de fraisage 56 est illustrée dans une position permettant le changement de l'outil après avoir subi une rotation de 90° autour d'un axe parallèle au rail dans le sens de la flèche F. Dans cette position, le palan 51 peut aligner la fraise 40 en regard du mandrin 41 de l'unité de fraisage. La fixation par cône morse de la fraise permet un changement rapide et aisé des fraises.Figure 8 shows in another view the principle of change of strawberries. Milling unit 55 located on the left of the figure is in train service position to mill the rail, while the milling unit 56 is illustrated in a position allowing the change of the tool after having been rotated 90 ° around a axis parallel to the rail in the direction of arrow F. In this position, the hoist 51 can align the cutter 40 in look of the mandrel 41 of the milling unit. Fixation by Morse taper of the strawberry allows a quick change and easy strawberries.

La figure 9 illustre le dispositif de refroidissement 17 situé à l'arrière des unités de fraisage. Ce dispositif est relié au châssis 2 du véhicule ferroviaire par un vérin 70 qui permet de relever le dit dispositif. Le piston de ce vérin 70 est relié au bâti 71 du refroidisseur par l'intermédiaire d'une pièce de liaison 72. Cette pièce de liaison 72 reçoit également une des extrémités d'un timon 73 dont l'autre extrémité est solidaire du cadre 9 formant la base de guidage de la deuxième unité de fraisage. Ce timon 73 permet l'entraínement et le guidage du refroidisseur. Le bâti 71 du refroidisseur comporte des roulettes de guidage 74 qui viennent prendre appui sur le rail en position de service. A l'intérieur du bâti 71, des chicanes 75 sont agencées de telle façon qu'elles provoquent un écoulement tourbillonnaire du fluide de refroidissement qui circule dans le bâti. Le bâti 71 comporte encore sur la partie supérieure une entrée 76 et une sortie 77 du fluide de refroidissement. La figure 10 illustre en coupe partielle le refroidisseur et montre un vérin 78 connecté à la pièce de liaison 72 et qui permet d'ajuster l'écartement entre les refroidisseurs associés à chacun des rails et d'assurer de ce fait un guidage transversal des refroidisseurs sur les rails.Figure 9 illustrates the cooling system 17 located at the rear of the milling units. These measures is connected to chassis 2 of the rail vehicle by a jack 70 which allows the said device to be raised. The piston of this jack 70 is connected to the frame 71 of the cooler via a connecting piece 72. This piece link 72 also receives one end of a drawbar 73 the other end of which is integral with frame 9 forming the guide base of the second milling unit. This drawbar 73 allows the drive and guidance of cooler. The frame 71 of the cooler includes guide rollers 74 which come to bear on the rail in service position. Inside the frame 71, baffles 75 are arranged in such a way that they cause a vortex flow of the coolant which circulates in the frame. Frame 71 has still on the upper part an entry 76 and an exit 77 of the coolant. Figure 10 illustrates in partial section the cooler and shows a jack 78 connected to the connecting piece 72 and which makes it possible to adjust the spacing between the coolers associated with each rails and thereby ensure transverse guidance coolers on the rails.

La figure 11 illustre le wagon de puissance utilisé dans l'installation de reprofilage des rails. Ce wagon de puissance fournit l'énergie électrique nécessaire à l'alimentation des unités de fraisage ainsi qu'à l'alimentation des unités de chauffage. Ce wagon de puissance est situé derrière le wagon de fraisage qui est en tête du convoi et devant un wagon illustré à la figure 12 qui porte des unités 80,81 de meulage et de finition permettant d'éliminer les stries laissées sur le rail par le travail des fraises. Ces unités de meulage ou de polissage sont par exemple du type décrit dans les brevets US 4 615 150 ou US 5 265 379. Les meules utilisées peuvent être des meules lapidaires, périphériques, des meules de forme ou des blocs abrasifs de forme à mouvement alternatif. Ce wagon est de plus équipé d'un dispositif d'aspiration et de stockage des poussières produites par le meulage. Le wagon de meulage comporte également une unité de mesure 82 située derrière les unités de meulage. Cette unité 82 permet de mesurer la qualité du reprofilage obtenu et grâce à un asservissement des unités de fraisage et des unités de chauffage, de corriger le cas échéant le réglage de la profondeur de coupe des unités de fraisage, et/ou la puissance de chauffe des unités de chauffage. Figure 11 illustrates the power wagon used in the rail reprofiling installation. This wagon of power provides the electrical energy needed to power milling units as well as food heating units. This power wagon is located behind the milling wagon which is at the head of the convoy and in front of a wagon shown in Figure 12 carrying units 80.81 grinding and finishing to eliminate the streaks left on the rail by the work of strawberries. These grinding or polishing units are by example of the type described in US Patents 4,615,150 or US 5,265,379. The grinding wheels used may be grinding wheels lapidaries, peripheral, grinding stones or reciprocating shaped abrasive blocks. This wagon is also equipped with a suction device and storage of dust produced by grinding. The cart also has a measuring unit 82 located behind the grinding units. This unit 82 allows to measure the quality of the reprofiling obtained and thanks to a servo control of milling units and heating, correct the setting of the cutting depth of milling units, and / or power heating of the heating units.

La figure 13 illustre en détail le dispositif permettant l'aspiration et le stockage des copeaux pendant l'opération de fraisage. La partie arrière du wagon de fraisage comporte un container à copeaux 90. Un tapis roulant 91 est agencé dans le fond du container 90. Derrière chacune des fraises 24,24' se trouve une bouche d'aspiration 32,32' connectée à un tuyau d'aspiration 92 qui débouche dans un dispositif séparateur 93. Un ventilateur 94, fixé sur le wagon, provoque l'aspiration des copeaux qui tombent dans le dispositif 93. Ce dispositif 93 est muni de pales 95 entraínées en rotation qui empêchent l'accumulation des copeaux à l'intérieur du dispositif et facilite leur évacuation vers le container 90 et leur distribution dans celui-ci.Figure 13 illustrates in detail the device for chip extraction and storage during operation milling. The rear part of the milling wagon has a 90 chip container. A conveyor belt 91 is arranged in the bottom of the container 90. Behind each strawberries 24,24 'there is a suction mouth 32.32 'connected to a suction pipe 92 which opens in a separating device 93. A fan 94, fixed on the wagon, causes the aspiration of the chips which fall into device 93. This device 93 is provided blades 95 driven in rotation which prevent accumulation chips inside the device and facilitates their evacuation to container 90 and their distribution In this one.

La figure 14 illustre l'opération de déchargement des copeaux. L'installation de reprofilage étant à l'arrêt, un camion benne 96 vient se ranger à proximité de l'installation. On déconnecte le tuyau 92 de l'embout reliant les bouches d'aspiration 32,32' et on le connecte à la sortie d'un récipient de décharge 97 situé en dessous du container 90 et dans lequel débouche le tapis roulant 91. La mise en marche du tapis roulant 91 provoque l'évacuation des copeaux vers le récipient de décharge 97.Figure 14 illustrates the operation of unloading shavings. With the reprofiling installation stopped, a tipper truck 96 is parked near the installation. The pipe 92 is disconnected from the end piece connecting the 32.32 'suction ports and connect it to the outlet a discharge container 97 located below the container 90 and into which the conveyor belt 91 opens. turning on the treadmill 91 causes evacuation chips to the discharge container 97.

Une grue hydraulique à pivot 98 montée sur le wagon de fraisage permet de déplacer le dispositif séparateur 93 en dessus du camion benne 96. Le ventilateur 94 provoque ensuite l'aspiration des copeaux tombés dans le récipient de décharge 97 vers le dispositif séparateur 93 qui les évacue dans la benne du camion. Dans une variante non illustrée, l'aspiration des copeaux peut être remplacée par un dispositif comme un tambour magnétique qui permet de récupérer les copeaux par attraction magnétique.A 98 pivot hydraulic crane mounted on the wagon milling tool moves the separating device 93 above the dump truck 96. The fan 94 causes then the suction of the chips which have fallen into the container discharge 97 to the separating device 93 which dumped into the truck’s dumpster. In a variant not illustrated, the chip extraction can be replaced by a device like a magnetic drum which allows collect the chips by magnetic attraction.

L'installation de reprofilage telle que décrite comporte un wagon de fraisage à l'avant, un wagon de puissance au centre et un wagon de meulage et de polissage des rails. Il va de soi que ces opérations peuvent être dissociées si par exemple les vitesses de travail ne sont pas les mêmes pour les différentes opérations. De même, on peut prévoir que les différentes unités (fraisage, chauffage, mesure, meulage) soient agencées sous un véhicule unique.The reprofiling installation as described comprises a milling wagon at the front, a power wagon in the center and a wagon for grinding and polishing rails. It goes without saying that these operations can be dissociated if for example the working speeds are not the same for the different operations. Likewise, we can provide that the different units (milling, heating, measurement, grinding) are arranged under a vehicle unique.
