Abstract

The grinder is mounted on a carriage (2), carried by a self powered vehicle (1). During rail grinding, the vehicle is fixed, stationary relative to the rail, whilst the grinding carriage moves to and fro along the rail. The distance between carriage and vehicle is adjustable. In addition to rail joints, other localised faults can be ground. During grinding, the carriage may be connected to the vehicle by an electrical supply cable (13). The grinder may have a rotary wheel, driven by a motor and the carriage is also driven back and forth. A lifting device (36) may lift the carriage into the vehicle. There may be several, e.g. two or more, grinding carriages independent of each other, on the vehicle. <IMAGE>

Description

Il est nécessaire, à côté des opérations d'entretien périodiques par reprofilage des rails d'une voie de chemin de fer, de procéder à des opérations d'entretien ponctuelles sur certains tronçons de longueur limitée, généralement très courts, telles les soudures d'abouts de rails, les passages à niveau ou les aiguillages. En effet, lors de la soudure d'abouts de rails, il se produit un bourrelet de soudure qu'il est indispensable d'éliminer. D'autre part, certains points ou zones des rails de la voie, soudés ou non, sont déformés par le trafic et doivent être reprofilés spécialement.It is necessary, in addition to periodic maintenance operations by reprofiling the rails of a railway track, to carry out ad hoc maintenance operations on certain sections of limited length, generally very short, such as welds of end of rails, level crossings or switches. In fact, when welding ends of rails, a weld bead occurs which it is essential to eliminate. In addition, certain points or zones of the rails of the track, welded or not, are deformed by traffic and must be specially reprofiled.

On connaît des modèles d'utilité allemand GM 7710195 et GM 7710735, du brevet français 1.479.320 et du brevet anglais 817.825, de petites machines de meulage dites manuelles. Ces petites machines sont déplaçables manuellement ou de façon motorisée le long de la voie et peuvent être immobilisées, fixées, aux rails de part et d'autre du joint à meuler. Un mouvement de va-et-vient de la tête de meulage, généralement commandé manuellement, parallèlement à l'axe du rail permet d'éliminer progressivement le défaut, notamment les bourrelets de soudure. Un pivotement du dispositif de meulage autour d'un axe parallèle à celui du rail permet de meuler toute la surface du champignon de ce rail.German utility models GM 7710195 and GM 7710735 are known, from French patent 1,479,320 and English patent 817,825, from small so-called manual grinding machines. These small machines can be moved manually or motorized along the track and can be immobilized, fixed, to the rails on either side of the grinding joint. A back-and-forth movement of the grinding head, generally controlled manually, parallel to the axis of the rail makes it possible to gradually eliminate the defect, in particular the weld beads. A pivoting of the grinding device about an axis parallel to that of the rail makes it possible to grind the entire surface of the head of this rail.

Ces machines ou dispositifs de meulage sont légers, peu puissants et de ce fait travaillent lentement. De plus, la qualité du travail dépend grandement de l'habileté de l'opérateur actionnant manuellement la machine.These grinding machines or devices are light, not very powerful and therefore work slowly. In addition, the quality of work greatly depends on the skill of the operator manually operating the machine.

On peut également utiliser des machines de reprofilage des rails conventionnelles qui sont constituées de véhicules automoteurs associés à des groupes d'unités de meulage permettant de traiter toute la surface du champignon du rail. Ces machines sont généralement réservées au reprofilage en continu du rail sur toute leur longueur. Elles peuvent toutefois exceptionnellement être utilisées pour le meulage d'un joint ou d'une zone isolée de faible longueur d'un rail, leur puissance généralement élevée permet de réduire sensiblement le temps de meulage d'un joint.It is also possible to use machines for reprofiling conventional rails which are made up of self-propelled vehicles associated with groups of grinding units making it possible to treat the entire surface of the rail head. These machines are generally reserved for continuous reprofiling of the rail over their entire length. They can however exceptionally be used for grinding a joint or an insulated area of short length of a rail, their generally high power makes it possible to significantly reduce the grinding time of a joint.

Ces machines conventionnelles, du type par exemple de celles décrites dans les brevets CH 680.597, CH 680.672 et CH 68 598 présentent toutefois deux inconvénients majeurs pour le meulage de joints ou de défauts ponctuels d'un rail.These conventional machines, of the type for example of those described in the patents CH 680.597, CH 680.672 and CH 68 598 however have two major drawbacks for grinding joints or point defects in a rail.

D'une part, ces machines de par leur construction sont longues, environ six à dix mètres selon les modèles, et lourdes, entre 15 et 25 tonnes. Pour effectuer l'opération de meulage d'un joint, la machine doit être déplacée entièrement de part et d'autre du joint plusieurs fois de suite. Il faut donc accélérer et freiner une masse très importante successivement à de faibles intervalles de temps. La machine doit également être déplacée sur une distance très grande par rapport à la longueur de la zone à meuler. Ceci entraîne des pertes de temps et un gaspillage d'énergie.On the one hand, these machines by their construction are long, around six to ten meters depending on the model, and heavy, between 15 and 25 tonnes. To perform the grinding operation of a joint, the machine must be moved completely on both sides of the joint several times in succession. It is therefore necessary to accelerate and brake a very large mass successively at short time intervals. The machine must also be moved a very long distance from the length of the area to grind. This results in wasted time and wasted energy.

D'autre part, la charge par essieu de ces machines est importante et engendre une déformation du rail au droit de la roue (cf. Die Eisenbannschiene, Wilhelm Ernst und Sohn, Berlin, p. 25), et donc au voisinage de la zone à meuler ce qui rend l'opération de meulage plus délicate et moins précise. Le résultat obtenu par de telles grosses machines pour le meulage de joints est ainsi peu productif par rapport au temps et à l'énergie dépensée.On the other hand, the axle load of these machines is high and generates a deformation of the rail in line with the wheel (cf. Die Eisenbannschiene, Wilhelm Ernst und Sohn, Berlin, p. 25), and therefore in the vicinity of the area to grind which makes the grinding operation more delicate and less precise. The result obtained by such large machines for grinding joints is thus not very productive in relation to the time and the energy expended.

Une inconvénient supplémentaire réside dans le fait que l'opérateur subit les forces d'accélération du mouvement de va-et-vient de la machine ce qui à la longue est très désagréable. On peut noter que cet inconvénient pour le personnel, qui était également présent dans les bourreuses traditionnelles de réfection du ballast de la voie a conduit à la conception des bourreuses en continu modernes.An additional drawback lies in the fact that the operator undergoes the forces of acceleration of the reciprocating movement of the machine which in the long run is very unpleasant. It can be noted that this drawback for the personnel, which was also present in the traditional tamping machines for repairing the track ballast, has led to the design of modern continuous tamping machines.

La machine de meulage selon l'invention a pour but de permettre le meulage de joints ou de zones de longueur reduite d'un rail de façon économique, rapide, avec précision et exactitude et sans inconvénients pour le personnel servant.The purpose of the grinding machine according to the invention is to allow the grinding of joints or areas of reduced length of a rail economically, quickly, with precision and accuracy and without disadvantages for the personnel serving.

La machine de meulage selon la présente invention tend à obvier aux inconvénients précités des machines, grandes ou petites, existantes et se distingue par les caractéristiques énumérées à la revendication 1.The grinding machine according to the present invention tends to obviate the aforementioned drawbacks of existing machines, large or small, and is distinguished by the characteristics listed in claim 1.

Le dessin annexe illustre schématiquement et à titre d'exemple deux formes d'exécution de la machine de meulage selon l'invention ainsi qu'à plus grande échelle, le chariot de meulage de ces machines.The accompanying drawing illustrates schematically and by way of example two embodiments of the grinding machine according to the invention and on a larger scale, the grinding carriage of these machines.

La figure 1 est une élévation d'une première forme d'exécution de la machine de meulage selon l'invention en position de déplacement d'un chantier à l'autre.Figure 1 is an elevation of a first embodiment of the grinding machine according to the invention in the displacement position from one site to another.

La figure 2 illustre la machine représentée à la figure 1 en position de travail, soit de meulage d une zone ponctuelle d'un rail.FIG. 2 illustrates the machine represented in FIG. 1 in the working position, that is to say for grinding a point area of a rail.

La figure 3 illustre la machine illustrée aux figures 1 et 2 en position de déplacement le long de la voie ferrée pour une courte distance.Figure 3 illustrates the machine illustrated in Figures 1 and 2 in the position of movement along the railway for a short distance.

La figure 4 est une vue, a plus grande échelle, en élevation du chariot de meulage de la machine.Figure 4 is a view, on a larger scale, in elevation of the grinding carriage of the machine.

La figure 5 est dans sa partie gauche une coupe suivant la ligne A-A de la figure 4 et dans sa partie droite une vue en bout du chariot de meulage.Figure 5 is in its left part a section along the line A-A of Figure 4 and in its right part an end view of the grinding carriage.

Les figures 6 et 7 illustrent une seconde forme d'exécution de la machine de meulage selon l'invention, en élévation, dans des positions correspondant à celles illustrées aux figures 1, respectivement 3.FIGS. 6 and 7 illustrate a second embodiment of the grinding machine according to the invention, in elevation, in positions corresponding to those illustrated in FIGS. 1, respectively 3.

En référence aux figures 1 à 5 la première forme d'exécution de la machine de meulage, notamment des joints d'abouts de rails, ou d'autres défauts localisés d'un rail d'une voie ferrée, est une machine dite rail-route, c'est-à-dire pouvant se déplacer soit le long d'une voie ferrée, soit sur route.With reference to FIGS. 1 to 5, the first embodiment of the grinding machine, in particular rail end joints, or other localized defects of a rail of a railroad track, is a machine called rail- road, that is to say able to move either along a railway track, or on road.

Cette machine de meulage comporte d'une part un véhicule 1 automoteur et producteur d'énergie, d'énergie électrique notamment, et d'autre part, au moins un chariot de meulage 2.This grinding machine comprises on the one hand a self-propelled vehicle 1 and producer of energy, in particular electrical energy, and on the other hand, at least one carriage grinding 2.

Le véhicule automoteur rail-route 1 comporte un chassis 3 monté sur un train routier avant 4 et un train routier arrière 5 propulsé par un moteur diesel conventionnel. Ce véhicule 1 comporte une cabine de pilotage 6 regroupant toutes les commandes habituelles d'un véhicule rail-route.The rail-road self-propelled vehicle 1 comprises a chassis 3 mounted on a front road train 4 and a rear road train 5 propelled by a conventional diesel engine. This vehicle 1 comprises a pilot cabin 6 grouping together all the usual commands for a rail-road vehicle.

Ce véhicule comporte encore des bogies 7 rétractables à l'aide de vérins hydrauliques 8,9 munis de roues permettant, en position de service (figure 2) de reposer sur les rails d'une voie ferrée et de soulever les trains-routiers 4,5.This vehicle also includes retractable bogies 7 using hydraulic cylinders 8, 9 fitted with wheels making it possible, in the service position (FIG. 2), to rest on the rails of a railway track and to lift the road trains 4, 5.

L'énergie hydraulique nécessaire à l'actionnement des vérins 8,9 est délivrée par un groupe hydraulique 10 alimenté par un moteur diesel 11 porté par le chassis 3. Ce moteur diesel 11 entraîne également un générateur électrique 12 qui, comme on le verra plus loin, alimentera en électricité les unités de meulage du chariot de meulage 2 par l'intermédiaire d'un câble électrique souple 13.The hydraulic energy required to actuate the cylinders 8, 9 is delivered by a hydraulic unit 10 powered by a diesel engine 11 carried by the chassis 3. This diesel engine 11 also drives an electric generator 12 which, as will be seen more away, will supply electricity to the grinding units of the grinding carriage 2 via a flexible electric cable 13.

Le véhicule automoteur est encore muni d'une cabine de commandes 14 des opérations de meulage regroupant les commandes des unités de meulage et du chariot de meulage luimême.The self-propelled vehicle is also provided with a grinding operations control cabin 14 grouping together the controls of the grinding units and of the grinding carriage itself.

Le chariot de meulage 2, illustré en détail aux figures 4 et 5, comporte un cadre muni de galets 15 destinés à coopérer avec les rails 16. Ce cadre porte de façon conventionnelle des unités de meulage, déplaçables angulairement autour d'un axe parallèle à celui du rail 16 à l'aide de vérins ou de moteurs électriques 17. Chaque unité de meulage comporte un moteur électrique 18 entrainant une meule lapidaire 19. Dans l'exemple illustré le chariot de meulage 2 comporte quatre unités de meulage 18,19 montées par paire dans des berceaux 20 articulés sur le cadre. La capacité d'enlèvement de métal des unités de meulage est déterminée par la force d'appui des meules 19 sur le rail et par leur vitesse de rotation.The grinding carriage 2, illustrated in detail in FIGS. 4 and 5, comprises a frame provided with rollers 15 intended to cooperate with the rails 16. This frame conventionally carries grinding units, angularly displaceable about an axis parallel to that of the rail 16 using jacks or electric motors 17. Each grinding unit comprises an electric motor 18 driving a lapidary wheel 19. In the example illustrated the grinding carriage 2 comprises four grinding units 18,19 mounted in pairs in cradles 20 articulated on the frame. The metal removal capacity of the grinding units is determined by the bearing force of the grinding wheels 19 on the rail and by their speed of rotation.

Le chariot de meulage est entouré de protections 21 portées par le caisson 22 d'un filtre 23 relié à une turbine 24 d'aspiration des poussières de meulage entrainée par un moteur électrique 25.The grinding carriage is surrounded by protections 21 carried by the casing 22 of a filter 23 connected to a turbine 24 for sucking grinding dust driven by an electric motor 25.

Le chariot de meulage comporte un dispositif de propulsion autonome formé ici par exemple d'un moteur électrique 26 entraînant un des galets 15 par une liaison à chaine 27.The grinding carriage comprises an autonomous propulsion device formed here for example of an electric motor 26 driving one of the rollers 15 by a chain link 27.

Le chariot de meulage est encore muni d'un mât repliable et télescopique 28 portant à son extrêmité un connecteur électrique 29 alimentant les différents moteurs électriques 18,25,26 en énergie lorsque ce connecteur est branché à l'extrêmité du câble électrique 13. L'extrêmité du mât 28 sert de point d'ancrage à un câble 30 de support du câble électrique 13. Ce câble 30 passe sur une poulie 31 d'un système d'enroulement 32 porté par le véhicule automoteur 1.The grinding carriage is also provided with a foldable and telescopic mast 28 carrying at its end an electrical connector 29 supplying the various electric motors 18,25,26 with energy when this connector is connected to the end of the electrical cable 13. L the end of the mast 28 serves as an anchor point for a cable 30 for supporting the electric cable 13. This cable 30 passes over a pulley 31 of a winding system 32 carried by the self-propelled vehicle 1.

Le chariot de meulage 2 comporte enfin des axes de relevage 33 destinés à coopérer avec des crochets 34 à l'extrêmité de bras 35 pivotants sur le chassis du véhicule automoteur sous l'action de vérins de relevage 36. Ainsi, grâce à ce dispositif de relevage le chariot 2 peut être porté par le véhicule automoteur (figure 1) pour ses déplacements d'un chantier à l'autre. Dans cette position portée par le véhicule, le bras télescopique 28 du chariot 2 est rentré et replié et le câble d'alimentation électrique 13 est déconnecté. Le câble de support 30 est décroché du mât 28.The grinding carriage 2 finally comprises lifting axes 33 intended to cooperate with hooks 34 at the end of pivoting arms 35 on the chassis of the self-propelled vehicle under the action of lifting cylinders 36. Thus, thanks to this device lifting the trolley 2 can be carried by the self-propelled vehicle (figure 1) for its movements from one site to another. In this position carried by the vehicle, the telescopic arm 28 of the carriage 2 is retracted and folded and the electrical supply cable 13 is disconnected. The support cable 30 is released from the mast 28.

Lorsque le véhicule automoteur rail-route arrive sur une voie ferrée à proximité d'un joint à meuler le véhicule s'aligne sur la voie et les bogies 6,7 sont descendus, coopérant avec les rails et soulèvent les trains routiers 4,5.When the rail-road self-propelled vehicle arrives on a railway track near a grinding joint, the vehicle aligns with the track and the bogies 6,7 are lowered, cooperating with the rails and lifting the road trains 4,5.

Le chariot 2 est descendu et posé sur les rails. Le mât 28 est relevé, relié au câble 30 et le câble électrique 13 est branché au connecteur 29.The carriage 2 is lowered and placed on the rails. The mast 28 is raised, connected to the cable 30 and the electric cable 13 is connected to the connector 29.

La machine de meulage est en position de travail (figure 2). Le lourd véhicule automoteur est immobilisé sur la voie. Le léger chariot 2, relié uniquement par les câbles 30 et 13 au véhicule 1, est entraîné dans un mouvement de va-et-vient de part et d'autre du joint à meuler par le moteur 26 et la liaison à chaine 27. La masse réduite et la courte longueur du chariot de meulage 2 permettent des mouvements de va-et-vient courts et rapides. Le poids du chariot étant très faible, la déformation du rail au droit des galets 15 est donc très faible ce qui améliore la précision du meulage.The grinding machine is in the working position (Figure 2). The heavy self-propelled vehicle is immobilized on the track. The light carriage 2, connected only by cables 30 and 13 to the vehicle 1, is driven in a reciprocating movement on either side of the joint to be ground by the motor 26 and the chain link 27. The reduced mass and the short length of the grinding carriage 2 allow short and rapid back-and-forth movements. The weight of the carriage being very low, the deformation of the rail in line with the rollers 15 is therefore very low, which improves the precision of grinding.

La principale caractéristique de cette machine de meulage, qui permet de résoudre le problème posé est de réaliser les buts et avantages proposés, est qu'en position de travail le chariot de meulage se déplace seul le long de la voie dans ses déplacements de va-et-vient, le véhicule automoteur restant immobile et servant alors uniquement à alimenter en énergie les organes du chariot et à en assurer le contrôle à partir du poste de pilotage 14.The main characteristic of this grinding machine, which solves the problem posed is to achieve the goals and advantages offered, is that in the working position the grinding carriage moves alone along the track in its movements of va- back and forth, the self-propelled vehicle remaining stationary and then serving only supplying power to the components of the truck and ensuring their control from the cockpit 14.

D'autres avantages découlent de cette configuration dont les principaux sont, notamment :

  • une meilleure inscription en courbe, la longueur du chariot de meulage étant petite.
  • Le contrôle de la zone meulée est facile soit depuis la cabine de pilotage 14, soit visuellement en se plaçant à côté du chariot de meulage.
  • Le confort des opérateurs est amélioré, ils peuvent soit rester sur le véhicule automoteur à l'arrêt et contrôler le meulage à distance, soit descendre de la machine et contrôler le meulage visuellement. En tous les cas, les opérateurs ne sont pas soumis à des accélérations et freinages multiples successifs.
Other advantages stem from this configuration, the main ones being, in particular:
  • better inscription on the curve, the length of the grinding carriage being small.
  • Control of the ground area is easy either from the cockpit 14, or visually by standing next to the grinding carriage.
  • Operators' comfort is improved, they can either remain on the self-propelled vehicle at a standstill and control grinding from a distance, or get off the machine and control grinding visually. In all cases, operators are not subject to successive multiple accelerations and brakes.

Lorsque de courtes distances doivent être franchies entre deux joints à meuler le chariot de meulage 2 peut rester sur la voie et être accouple mécaniquement à l'aide d'un timon 37 au véhicule automoteur qui peut ainsi tracter le chariot le long de la voie.When short distances have to be crossed between two joints to be ground, the grinding carriage 2 can remain on the track and be mechanically coupled using a drawbar 37 to the self-propelled vehicle which can thus tow the carriage along the track.

La seconde forme d'exécution illustrée aux figures 6 et 7 de la machine de meulage se différencie par rapport à la première déjà décrite uniquement du fait que le véhicule automoteur est un véhicule ferroviaire uniquement. Les trains routiers 4,5 sont donc supprimés. De plus, les commandes du chariot de meulage 2 sont regroupées dans la cabine de pilotage du véhicule ferroviaire. Enfin, dans cette exécution, le véhicule automoteur ferroviaire ne comporte qu'un moteur diesel servant à sa traction ainsi qu'à l'entraînement du groupe hydraulique et du générateur électrique alimentant les moteurs du chariot de meulage 2.The second embodiment illustrated in Figures 6 and 7 of the grinding machine differs from the first already described only because the self-propelled vehicle is a rail vehicle only. Road trains 4.5 are therefore eliminated. In addition, the controls of the grinding carriage 2 are grouped in the cockpit of the rail vehicle. Finally, in this embodiment, the self-propelled rail vehicle only has a diesel engine used for its traction as well than driving the hydraulic unit and the electric generator supplying the motors of the grinding carriage 2.

Dans des variantes, on peut imaginer que le véhicule automoteur comporte plusieurs chariots de meulage 2, notamment l'un à l'arrière comme décrit et illustré précédemment et l'autre à l'avantIn variants, one can imagine that the self-propelled vehicle comprises several grinding carriages 2, in particular one at the rear as described and illustrated above and the other at the front
