Description

La présente invention concerne une machine roulante pour excaver le ballast des voies ferrées, particulièrement une dégarnisseuse-cribleuse, munie d'une chaine d'excavation ayant un brin inférieur transversal qui passe au-dessous de la voie, et des moyens pour ramasser le ballast aux emplacements des appareils de voie, prévue pour avancer sur une voie de service remplaçant provisoirement l'appareil de voie.The present invention relates to a rolling machine for excavating ballast from railways, in particular a stripping machine, provided with an excavation chain having a transverse lower strand which passes below the track, and means for picking up ballast. at the switchgear locations, intended to advance on a service track temporarily replacing the switchgear.

On connait déjà des machines d'excavation, notamment des dégarnisseuses-cribleuses adaptées à traiter le lit de ballast des voies, en particulier les emplacements des appareils de voie. Une de ces machines actuellement connues, est munie d'une chaîne d'excavation qui passe sous l'appareil de voie et qui transporte le matériel excavé sur un crible où ce matériel est nettoyé et le ballast propre remis sur la voie; les détritus sont chargés sur des wagons se trouvant sur une voie parallèle ou en tête de machine. Pour atteindre le ballast se trouvant en dehors de la largeur du lit normal, dans la zone où l'appareil de voie s'élargit. le brin inférieur de cette chaine d'excavation peut être allongé manuellement. Comme indiqué sur la figure 1, la portée normale du brin inférieur est représentée par la distance A. Au fur et à mesure de l'élargissement de l'appareil de voie, la machine doit être arrêtée pour élargir le brin horizontal inférieur de la chaine d'excavation passant sous la voie au moyen d'un élément supplémentaire d'une largeur B permettant d'excaver une largeur de lit A+B, puis d'un nouvel élément pour excaver une largeur A+2B etc. Le rallongement du brin horizontal exige chaque fois une interruption de l'opération et représente un travail important, diminuant considérablement le rendement de la machine.Excavation machines are already known, in particular screen-strippers suitable for treating the ballast bed of the tracks, in particular the locations of the track apparatus. One of these machines currently known, is provided with an excavation chain which passes under the switchgear and which transports the excavated material on a screen where this material is cleaned and the clean ballast put back on the track; rubbish is loaded onto wagons on a parallel track or at the head of the machine. To reach the ballast outside the width of the bed normal, in the area where the switchway widens. the lower strand of this excavation chain can be extended manually. As shown in Figure 1, the normal reach of the lower strand is represented by the distance A. As the track gauge widens, the machine must be stopped to widen the lower horizontal strand of the chain excavation passing under the track by means of an additional element with a width B making it possible to excavate a bed width A + B, then with a new element for excavating a width A + 2B etc. The extension of the horizontal strand each time requires an interruption of the operation and represents significant work, considerably reducing the efficiency of the machine.

Selon un autre type de machine connu, la cribleuse est munie de chenilles, lesquelles sont mises en oeuvre dès que l'appareil de voie est démonté. Elle est équipée soit de chaines conventionnelles, comme la machine précédemment décrite, soit de chaines pivotantes. Une telle machine présente l'inconvénient de devoir charger les détritus sur une voie parallèle. En outre, il est difficile de maintenir la profondeur de creusage, ainsi que l'inclinaison de la plate-forme, d'une façon constante.According to another known type of machine, the screener is provided with tracks, which are implemented as soon as the track device is dismantled. It is fitted either with conventional chains, like the machine described above, or with pivoting chains. Such a machine has the disadvantage of having to load the trash on a parallel track. In addition, it is difficult to maintain the digging depth, as well as the inclination of the platform, in a constant manner.

En règle générale, lors de l'entretien de l'emplacement des appareils de voie, tels que des aiguillages, des branchements-traversées ou des croisements non seulement on nettoie le ballast, mais on profite de l'occasion pour remplacer ou réviser l'appareil de voie. Pour effectuer ces travaux, il est connu de remplacer l'appareil de voie enlevé par une voie de service, permettant le passage de la dégarnisseuse-cribleuse, avant la pose d'un nouvel appareil de voie. Cette voie de service est installée provisoirement et ses rails ne sont pas maintenus par des traverses mais simplement par des barres d'écartement, ce qui facilite l'enlèvement et la redépose du ballast. Cependant, il existe toujours la difficulté mentionnée précédemment de devoir adapter la largeur du brin inférieur de la chaine d'excavation à la largeur du lit de ballast.As a general rule, during the maintenance of the location of the track devices, such as switches, crossings or crossings, not only do you clean the ballast, but you take the opportunity to replace or revise the switchgear. To carry out this work, it is known to replace the removed track device with a service track, allowing the passage of the screen stripper, before installing a new track device. This service track is provisionally installed and its rails are not held by crosspieces but simply by spreader bars, which facilitates the removal and redeposition of the ballast. However, there is still the previously mentioned difficulty of having to adapt the width of the lower strand of the excavation chain to the width of the ballast bed.

La présente invention vise à remédier à ces inconvénients en proposant une machine prévue pour rouler sur la voie de service et qui permet de nettoyer facilement le ballast aux emplacements des appareils de voie.The present invention aims to remedy these drawbacks by proposing a machine designed to run on the service track and which makes it possible to easily clean the ballast at the locations of the track apparatus.

Dans ce but, l'invention est caractérisée par les caractéristiques de la revendication 1.For this purpose, the invention is characterized by the features of claim 1.

Donc par ce dispositif d'excavation auxiliaire, on peut très facilement déplacer le ballast qui se trouve en dehors de la portée de la chaine d'excavation normale, vers l'axe de la voie afin qu'il puisse être pris en charge et monté vers le crible par cette chaine d'excavation normale.So by this auxiliary excavation device, one can very easily move the ballast which is outside the reach of the normal excavation chain, towards the axis of the track so that it can be taken in charge and mounted to the screen through this normal excavation chain.

De préférence, ce dispositif d'excavation auxiliaire peut être constitué par une chaine auxiliaire à creusage continu. En outre, afin de pouvoir utiliser la machine dans n'importe quelle direction pour tous les types d'appareils de voie, on peut de préférence prévoir un dispositif d'excavation auxiliaire de chaque côté de la machine. Il est également possible d'utiliser une pelle mécanique montée sur la machine comme dispositif d'excavation auxiliaire.Preferably, this auxiliary excavation device can be constituted by an auxiliary chain with continuous digging. In addition, in order to be able to use the machine in any direction for all types of switchgear, it is preferably provide an auxiliary excavation device on each side of the machine. It is also possible to use a mechanical shovel mounted on the machine as an auxiliary excavation device.

Cette machine présente les avantages suivants : Elle permet tout d'abord une excavation continue de toute la zone de l'appareil de voie ainsi que le chargement des criblures sans utilisation de la voie parallèle. En équipant la machine de deux dispositifs auxiliaires disposés de part et d'autre de ladite machine, il est possible d'excaver des appareils de voie doubles en un seul passage. Par ailleurs, avec cette machine, il est possible d'obtenir une égalisation parfaite du ballast récupéré lors d'un deuxième passage avec la chaine d'excavation principale et les chaines d'excavation auxiliaires, le ballast superflu étant chargé lors du deuxième passage.This machine has the following advantages: First of all, it allows continuous excavation of the entire area of the track apparatus as well as loading of screenings without using the parallel track. By equipping the machine with two auxiliary devices arranged on either side of said machine, it is possible to excavate double track devices in a single pass. Furthermore, with this machine, it is possible to obtain perfect equalization of the ballast recovered during a second pass with the main excavation chain and the auxiliary excavation chains, the superfluous ballast being loaded during the second pass.

Dans ce qui suit, l'invention est exposée plus en détail à l'aide des dessins représentant, schématiquement, plusieurs modes d'exécution de la machine.In what follows, the invention is explained in more detail using the drawings showing, schematically, several embodiments of the machine.

En se référant aux figures 3 et 4, la machine, une dégarnisseuse-cribleuse, roule sur une voie de service 1 qui a été installée sur le ballast 2 à l'emplacement de l'ancien appareil de voie, après le démontage de celui-ci, d'une manière connue en soi. La machine, qui avance dans la direction indiquée par la flèche F1, comporte un châssis 3 roulant au moyen de boggies 4,5 sur la voie de service 1. Sur ce châssis 3 est montée une chaine d'excavation principale 6 d'une construction normale et connue en soi, dont le brin inférieur 6a passe sous la voie de service 1 pour excaver le ballast lequel est ensuite transporté, par l'intermédiaire de sections inclinées, vers le sommet de la chaine d'excavation 6, au-dessus de l'ouverture d'entrée d'un crible à vibration 8. Un dispositif 7 permet d'ajuster la position de la chaine d'excavation principale 6. Le ballast nettoyé tombe sur un transporteur 9 pour être redéposé derrière la zone d'excavation. Il est prévu deux transporteurs 9,9', situés chacun au-dessus de chaque rail. Sur la figure 4 on a illustré de quelle manière ces transporteurs 9,9' peuvent être tournés autour d'un axe vertical afin de régler leur position pour permettre de faire tomber le ballast nettoyé à l'endroit désiré. Le déplacement possible de ces transporteur 9,9' est illustré par les doubles flèches F2.Referring to Figures 3 and 4, the machine, a stripper-screener, rolls on a service track 1 which was installed on the ballast 2 at the location of the old track device, after dismantling of this, in a manner known per se. The machine, which advances in the direction indicated by the arrow F1, comprises a chassis 3 rolling by means of bogies 4.5 on the service track 1. On this chassis 3 is mounted a main excavation chain 6 of a construction normal and known per se, the lower strand 6a of which passes under the service track 1 to excavate the ballast which is then transported, by means of inclined sections, to the top of the excavation chain 6, above the entry opening of a vibrating screen 8. A device 7 makes it possible to adjust the position of the main excavation chain 6. The cleaned ballast falls on a conveyor 9 to be redeposited behind the excavation area. Two 9.9 'conveyors are provided, each located above each rail. In Figure 4 there is illustrated how these conveyors 9,9 'can be rotated about a vertical axis in order to adjust their position to allow to drop the cleaned ballast at the desired location. The possible movement of these conveyor 9,9 ′ is illustrated by the double arrows F2.

Les déchets résultant du criblage sont repris par un transporteur 10 qui les transporte dans la direction d'avancement de la machine, sur un autre transporteur 11 de telle manière que ces déchets peuvent être chargés sur un wagon de transport disposé à l'avant de la machine, non illustré, ou être déchargés directement à côté de la voie ou sur un wagon de transport se déplaçant sur une voie parallèle, et dans ce but, le transporteur 11 peut également tourner autour d'un axe vertical d'une manière connue.The waste resulting from the screening is taken up by a conveyor 10 which transports it in the direction of advancement of the machine, on another conveyor 11 so that this waste can be loaded on a transport wagon placed at the front of the machine, not illustrated, or be unloaded directly next to the track or on a transport wagon moving on a parallel track, and for this purpose, the conveyor 11 can also rotate around a vertical axis in a known manner.

Selon l'invention, il est prévu deux chaines d'excavation auxiliaires 12,12' munies de pelles 13 et disposées de part et d'autre du châssis 3 et qui permettent de ramasser tout le ballast situé en dehors de la portée de la chaine d'excavation principale 6. Ces chaines d'excavation auxiliaires 12.12' sont mises en action dès que le lit de ballast s'élargit aux emplacements des appareils de voie et sont prévues pour ramasser la totalité du ballast dépassant de la portée A de la chaine d'excavation principale 6, comme illustré dans les figures 2 et 5. La figure 2 montre comment, selon la forme de l'appareil de voie, la chaine auxiliaire 12 est mise en action et est déployée progressivement pour couvrir toute la zone qui était hors de portée de la chaine d'excavation principale 6 au fur et à mesure de l'élargissement du lit de ballast. Cette chaine auxiliaire 12 ne soulève pas le ballast mais l'excave en le déplaçant dans un plan essentiellement horizontal vers l'axe de la voie où il est repris par la chaine d'excavation principale 6. Ce ballast déplacé est illustré par le tas 2a figure 5. La portée maximum des deux chaines d'excavation auxiliaires est naturellement adaptée à la largeur maximum des appareils de voie.According to the invention, two auxiliary excavation chains 12, 12 ′ are provided, provided with shovels 13 and arranged on either side of the chassis 3 and which make it possible to pick up all the ballast located outside the range of the chain. of main excavation 6. These auxiliary excavation chains 12.12 'are put into action as soon as the ballast bed widens at the locations of the track equipment and are provided to collect all of the ballast protruding from the range A of the chain main excavation 6, as illustrated in FIGS. 2 and 5. FIG. 2 shows how, depending on the shape of the switchgear, the auxiliary chain 12 is put into action and is gradually deployed to cover the entire area which was out of reach of the main excavation chain 6 as the ballast bed widens. This auxiliary chain 12 does not lift the ballast but the excavate by moving it in an essentially horizontal plane towards the axis of the track where it is taken up by the main excavation chain 6. This displaced ballast is illustrated by heap 2a figure 5. The maximum reach of the two auxiliary excavation chains is naturally adapted to the maximum width of the switches and crossings.

En nous référant aux figures 4, 5, 6 et 7 plus particulièrement, nous allons maintenant décrire d'une manière plus détaillée les chaines d'excavation auxiliaires 12,12' qui sont disposées dans un plan perpendiculaire à la voie mais qui travaillent dans un plan horizontal grâce à des pelles 13 illustrées figure 7.With particular reference to FIGS. 4, 5, 6 and 7, we will now describe in a more detailed manner the auxiliary excavation chains 12, 12 ′ which are arranged in a plane perpendicular to the track but which work in a horizontal plane using shovels 13 illustrated in FIG. 7.

Nous ne décrirons ci-après qu'une chaine d'excavation auxiliaire 12 étant entendu que l'autre chaine d'excavation auxiliaire 12' lui est symétrique et comporte les mêmes éléments, comme illustré figure 4.We will only describe below an auxiliary excavation chain 12, it being understood that the other auxiliary excavation chain 12 ′ is symmetrical to it and has the same elements, as illustrated in FIG. 4.

Sur le châssis 3 sont articulés autour d'un axe 16 vertical deux bras 17,17a superposés, entre les extrémités desquels est montée une pièce formant pivot 15 qui tourne autour d'un axe vertical. Sur cette dernière sont articulés deux leviers 14, 14a auxquels la chaine d'excavation auxiliaire 12 est suspendue. Les deux leviers 14, 14a sont chacun articulés sur un axe horizontal 18, 18a porté par le pivot 15. Sur la figure 5, on a illustré la manière dont est fixée la chaine d'excavation auxiliaire 12 aux leviers 14.14a. à savoir pour le bras 14, par l'intermédiaire d'un pivot 21 porté par une projection 20 solidaire du carter de la chaine 12, et pour le bras 14a par l'intermédiaire d'une articulation analogue.On the chassis 3 are articulated around a vertical axis 16 two superimposed arms 17, 17a, between the ends of which is mounted a part forming a pivot 15 which rotates around a vertical axis. On the latter are articulated two levers 14, 14a to which the auxiliary excavation chain 12 is suspended. The two levers 14, 14a are each articulated on a horizontal axis 18, 18a carried by the pivot 15. In FIG. 5, the manner in which the auxiliary excavation chain 12 is fixed to the levers 14.14a. namely for the arm 14, by means of a pivot 21 carried by a projection 20 secured to the casing of the chain 12, and for the arm 14a by means of a similar articulation.

Pour faire tourner la chaine d'excavation auxiliaire 12 autour du pivot 15, suivant la double flèche F3 (fig.6), il est prévu un câble 22 passant sur une roue de renvoi 23 et actionné par un cylindre 24 (fig.4). Ce dispositif permet de tracter la chaine d'excavation auxiliaire 12 dans la position angulaire voulue à l'encontre de la force de résistance résultant de l'avance de la machine et également de régler la largeur du travail.To rotate the auxiliary excavation chain 12 around the pivot 15, along the double arrow F3 (fig. 6), a cable 22 is provided passing over a deflection wheel 23 and actuated by a cylinder 24 (fig. 4) . This device makes it possible to tow the auxiliary excavation chain 12 in the desired angular position against the resistance force resulting from the advance of the machine and also to adjust the width of the work.

De cette manière, il est possible d'une part de régler la largeur maximum de la chaine d'excavation auxiliaire 12 en faisant basculer les bras 17 autour de l'axe 16 et d'autre part de faire varier la largeur effective de la chaine auxiliaire 12 pendant le travail en faisant basculer celle-ci autour du pivot vertical 15. En reprenant la figure 2, on peut voir deux positions angulaires possibles de la chaine d'excavation auxiliaire 12 après basculement autour du pivot 15.In this way, it is possible on the one hand to adjust the maximum width of the auxiliary excavation chain 12 by tilting the arms 17 around the axis 16 and, on the other hand, varying the effective width of the auxiliary chain 12 during work by tilting the latter around the vertical pivot 15. Taking again figure 2, we can see two possible angular positions of the auxiliary excavation chain 12 after tilting around the pivot 15.

Sur la figure 5 on a montré d'une manière schématique un vérin 19 permettant d'ajuster la hauteur, respectivement l'inclinaison de la chaine auxiliaire 12 qui peut tourner selon la double flèche F4 autour des axes horizontaux 18, 18a.In Figure 5 there is shown schematically a cylinder 19 for adjusting the height, respectively the inclination of the auxiliary chain 12 which can rotate according to the double arrow F4 around the horizontal axes 18, 18a.

Sur la figure 4, on a montré les éléments de l'autre chaîne d'excavation auxiliaire 12' par les mêmes références que celles de la première chaine d'excavation auxiliaire 12, mais avec un prime, à savoir: le levier 14', le pivot 15', l'axe vertical 16', le bras 17' (visible également sur la figure 5), le cable 22' et enfin le cylindre 24'.In FIG. 4, the elements of the other auxiliary excavation chain 12 ′ have been shown by the same references as those of the first auxiliary excavation chain 12, but with a bonus, namely: the lever 14 ′, the pivot 15 ', the vertical axis 16', the arm 17 '(also visible in Figure 5), the cable 22' and finally the cylinder 24 '.

Sur les figures 8 et 9, on a illustré une deuxième forme d'exécution de la chaine d'excavation auxiliaire 12 comportant des pelles 13, la machine se déplaçant toujours dans le sens de la flèche F1. Dans ce cas, cette chaîne auxiliaire 12 travaille dans un plan incliné, et les pelles 13 ne font pas que pousser le ballast dans un plan horizontal, comme dans la forme d'exécution précédente, mais le soulèvent pour le jeter directement en avant ou dans les pelles de la chaine d'excavation principale 6, sur le brin ascendant de cette chaîne. Cette chaine auxiliaire 12 est également montée d'une manière réglable sur le châssis 3 de la machine. Par la flèche F6 on a illustré le sens de ramassage du ballast par les pelles 13 qui le jettent sur le brin ascendant de la chaine principale 6 au moyen duquel il est transporté vers le crible dans le sens de la flèche F7.In Figures 8 and 9, there is illustrated a second embodiment of the auxiliary excavation chain 12 comprising shovels 13, the machine always moving in the direction of arrow F1. In this case, this auxiliary chain 12 works in an inclined plane, and the shovels 13 do not only push the ballast in a horizontal plane, as in the previous embodiment, but lift it to throw it directly forward or into the shovels of the main excavation chain 6, on the ascending strand of this chain. This auxiliary chain 12 is also mounted in an adjustable manner on the chassis 3 of the machine. The arrow F6 illustrates the direction in which the ballast is picked up by the shovels 13 which throw it onto the ascending strand of the main chain 6 by means of which it is transported towards the screen in the direction of the arrow F7.

Sur les figures 10 et 11 est illustrée une troisième forme d'exécution du dispositif d'excavation auxiliaire. Au lieu d'une chaine excavatrice travaillant de façon continue, il est prévu une pelle mécanique 30 articulée au châssis 3 par l'intermédiaire d'un axe d'articulation horizontal 35. Cette pelle mécanique 30 comprend un tube télescopique 31 avec un bras 32 extensible, selon la double flèche F9, à l'extrémité duquel est articulée d'une manière connue, par l'intermédiaire d'un système de vérins 33, la pelle 34. Un vérin 36 articulé d'une part sur le châssis 3 et d'autre part sur le tube télescopique 31 permet de basculer la pelle mécanique 30 autour de l'axe 35 vers le haut ou vers le bas selon la flèche F8.In Figures 10 and 11 is illustrated a third embodiment of the auxiliary excavation device. Instead of an excavator chain working continuously, there is provided a mechanical shovel 30 articulated to the chassis 3 by means of a horizontal articulation axis 35. This mechanical shovel 30 comprises a telescopic tube 31 with an arm 32 extendable, according to the double arrow F9, at the end of which is articulated in a known manner, by means of a system of jacks 33, the shovel 34. A jack 36 articulated on the one hand on the chassis 3 and on the other hand on the telescopic tube 31 makes it possible to tilt the mechanical shovel 30 around the axis 35 upwards or downwards according to arrow F8.

Donc, pendant le travail, partant de la position illustrée figure 10 avec la pelle en position basse, celle-ci creuse et déplace le ballast vers l'axe de la voie en rentrant le tube 32, puis elle est basculée vers le haut, déployée de nouveau vers l'extérieur et ensuite basculée vers le bas pour recommencer l'opération.So, during work, starting from the position illustrated in Figure 10 with the shovel in the low position, it digs and moves the ballast towards the axis of the track by returning the tube 32, then it is tilted upwards, deployed again outwards and then tilted down to start the operation again.

L'invention n'est, bien entendu, pas limitée aux formes d'exécution décrites, mais laisse la possibilité de prévoir de nombreuses variantes.The invention is, of course, not limited to the embodiments described, but leaves the possibility of providing numerous variants.
