Description

La présente invention se rapporte à un procédé pour le renouvellement d'un appareil de voie et au train pour la mise en oeuvre de ce procédé.The present invention relates to a method for the renewal of a switchgear and to the train for the implementation of this method.

Contrairement au renouvellement des voies qui peut être à l'heure actuelle effectué d'une manière entièrement mécanisée au moyen d'installations spéciales décrites notamment dans le brevet suisse No.583.822, le renouvellement des appareils de voie, ou aiguillages, n'a pu être effectué jusqu'ici que d'une manière largement manuelle.Contrary to the renewal of the tracks which can at the present time be carried out in a fully mechanized way by means of special installations described in particular in the Swiss patent No.583.822, the renewal of the switches and crossings, could not so far only be done largely manually.

On connaît des dispositifs permettant le remplacement des aiguillages complets à l'aide de plusieurs boggies. Dans ce cas, l'aiguillage à remplacer est tout d'abord surélevé d'une hauteur déterminée, au moyen de dispositifs de levage indépendants, puis on pose sous l'aiguillage soutenu en position surélevée par le dispositif de levage, des rails auxiliaires sur lesquels on fait ensuite se déplacer les boggies; on abaisse l'aiguillage sur les boggies et on le transporte à l'aide de celui-ci vers un emplacement de démontage. La pose de l'aiguillage neuf s'effectue par le processus inverse. Ce dispositif nécessite l'utilisation de moyens de levage particuliers, par exemple des dispositifs de levage hydrauliques, qui prennent appui de part et d'autre des rails et qui sont donc encombrants. Les anciens et nouveaux aiguillages étant transportés à plat sur les boggies, ils occupent un large emplacement qui dépasse le gabarit de la voie. Il est donc nécessaire, lors du transport de ces aiguillages ou parties d'aiguillages, d'arrêter tout trafic sur les voies parallèles et de dégager le long du trajet tout ce qui pourrait gêner le passage de ce convoi spécial. De plus, ces dispositifs nécessitent plusieurs interventions successives qui ne sont pas rationnelles.Devices are known which allow complete switches to be replaced using several bogies. In this case, the switch to be replaced is first of all raised by a determined height, by means of independent lifting devices, then auxiliary rails are placed under the switch supported in the raised position by the lifting device. which then move the bogies; the switch is lowered on the bogies and transported using it to a disassembly location. The installation of the new switch is carried out by the reverse process. This device requires the use of specific lifting means, for example hydraulic lifting devices, which bear on either side of the rails and which are therefore bulky. The old and new switches being transported flat on the bogies, they occupy a large space which exceeds the gauge of the track. It is therefore necessary, during the transport of these switches or parts of switches, to stop all traffic on the parallel tracks and to clear along the route everything that could hinder the passage of this special convoy. In addition, these devices require several successive interventions which are not rational.

On connaît également des wagons-grues pour transporter et manipuler l'aiguillage complet ou en plusieurs parties.There are also known crane wagons for transporting and handling the complete switch or in several parts.

Le but de la présente invention est de créer un procédé et un dispositif qui permettent un changement rationnel des appareils de voie et surtout qui permettent de transporter l'ancien appareil et le nouveau par un convoi normal qui respecte le gabarit de la voie sans couper la circulation sur les voies parallèles.The purpose of the present invention is to create a method and a device which allow rational change of the track apparatus and especially which make it possible to transport the old apparatus and the new one by a normal convoy which respects the gauge of the track without cutting the traffic on parallel tracks.

A cet effet, le procédé selon l'invention est caractérisé par le fait que le nouvel appareil de voie est prémonté en atelier en au moins deux éléments, le cas échéant à l'exception des traverses dont la longueur dépasse une longueur déterminée ou à l'exception des traverses d'extrémité des éléments dépassant une longueur déterminée, que ces éléments neufs et le cas échéant les traverses neuves isolées, sont transportés vers le chantier dans un wagon surbaissé, lesdits éléments étant maintenus dans une position inclinée dans laquelle ils ne dépassent pas le gabarit prescrit, que l'on sépare l'ancien appareil en au moins deux éléments correspondant aux éléments neufs prémontés et que l'on lève ces anciens éléments à travers l'intérieur d'un cadre vide d'un wagon de travail dont la longueur intérieure est supérieure à la longueur des éléments et dont la largeur intérieure peut être agrandie jusqu'à une valeur supérieure à la largeur maximale des éléments, après avoir le cas échéant démonté les anciennes traverses dont la longueur dépasse une longueur déterminée ou les traverses d'extrémité des anciens éléments dépassant une longueur déterminée, que ces anciens éléments enlevés sont transportés sur un autre wagon de transport surbaissé et maintenus dans une position dans laquelle ils ne dépassent pas le gabarit prescrit et que les éléments neufs prémontés sont transportés au-dessus dudit cadre vide et abaissés à travers ce cadre et posés, le cas échéant après que l'on ait mis en place les traverses neuves isolées.To this end, the method according to the invention is characterized in that the new switchgear is pre-assembled in the workshop in at least two elements, where appropriate with the exception of sleepers whose length exceeds a determined length or at least with the exception of the end crossmembers of elements exceeding a determined length, that these new elements and, where applicable, the isolated new sleepers, are transported to the site in a low-wagon, said elements being kept in an inclined position in which they do not protrude not the prescribed template, that the old device is separated into at least two elements corresponding to the new pre-assembled elements and that these old elements are lifted through the interior of an empty frame of a working wagon the internal length is greater than the length of the elements and the internal width of which can be increased to a value greater than the maximum width of the elements, after having if necessary removed é the old sleepers whose length exceeds a determined length or the end sleepers of the old elements exceeding a determined length, that these old removed elements are transported on another transport wagon lowered and kept in a position in which they do not exceed the prescribed template and that the new pre-assembled elements are transported above said empty frame and lowered through this frame and installed, if necessary after having installed the new isolated sleepers.

En général et dans les cas normaux, il est tout au plus nécessaire de déposer et poser séparément seulement les traverses les plus longues de l'élément de coeur d'un aiguillage, en principe pas plus de trois ou quatre traverses, et si l'aiguillage a des dimensions relativement réduites cela n'est même pas nécessaire, donc le procédé selon l'invention permet de prémonter totalement en atelier tous les éléments y compris l'élément de coeur, sauf dans des cas exceptionnels. C'est seulement pour les aiguillages de grande dimension qu'il pourrait être nécessaire d'enlever outre les traverses les plus longues de l'élément de coeur quelques traverses d'extrémité des autres éléments, donc en général de l'élément intermédiaire et de l'élément de lames afin qu'ils puissent être transportés au lieu de travail.In general and in normal cases, it is at most necessary to deposit and lay separately only the longest crosspieces of the core element of a switch, in principle not more than three or four crosspieces, and if the referral has relatively small dimensions this is not even necessary, therefore the method according to the invention makes it possible to completely pre-assemble in the workshop all the elements including the core element, except in exceptional cases. It is only for large switches that it may be necessary to remove, in addition to the longer crosspieces of the core element, some end crosspieces from the other elements, therefore in general from the intermediate element and from the blade element so that they can be transported to the workplace.

Il est connu du DE-A-2 228 196 un train de renouvellement muni d'un wagon cadre qui est extensible latéralement afin de permettre le levage ou la pose de différents éléments de la voie entre les côtés du cadre. L'extension latérale du cadre se fait de façon symétrique au moins par rapport à un axe du cadre transversal à la voie. Ce déploiement symétrique du cadre se fait, au détriment du gabarit de la voie, sur toute la longueur du cadre, même pour le renouvellement d'un aiguillage dont une petite partie seulement présente une longueur dépassant le gabarit. Ce déploiement est d'autant plus important quand le renouvellement s'opère sur une partie en courbe de la voie. D'autre part le déploiement symétrique du cadre engendre des efforts de flexion inutiles sur les deux traverses d'extrémité du cadre.DE-A-2 228 196 discloses a renewal train provided with a frame wagon which is extendable laterally in order to allow the lifting or the laying of different elements of the track between the sides of the frame. The lateral extension of the frame is done symmetrically at least with respect to an axis of the frame transverse to the track. This symmetrical deployment of the frame is done, to the detriment of the gauge of the track, over the entire length of the frame, even for the renewal of a switch, of which only a small part has a length exceeding the gauge. This deployment is all the more important when the renewal takes place on a curved part of the track. On the other hand the symmetrical deployment of the frame generates unnecessary bending forces on the two end crossmembers of the frame.

Le train pour effectuer le renouvellement de l'appareil de voie est caractérisé par la clause caractérisante de la revendication 4.The train for renewing the switchgear is characterized by the characterizing clause of claim 4.

Ce procédé permet donc de poser des appareils de voie prémontés, en deux, préférablement en trois éléments, de les transporter d'une manière rationnelle dans des wagons surbaissés sans dépassement du gabarit et avec des trains normaux, d'échanger le matériel sans occuper les voies parallèles donc sans interrompre le trafic et enfin, grâce à la mécanisation intégrale, en utilisant un temps de travail et une main-d'oeuvre restreints.This process therefore makes it possible to install pre-assembled track devices, in two, preferably in three elements, to transport them in a rational manner in lowered wagons without exceeding the gauge and with normal trains, to exchange the material without occupying the parallel tracks therefore without interrupting the traffic and finally, thanks to the integral mechanization, by using a working time and a restricted manpower.

Le train proposé permet par son cadre extensible asymétriquement de ne déborder le gabarit de la voie que là où c'est nécessaire, de mieux inscrire le cadre travaillant sur un tronçon en courbe de la voie, de limiter les efforts de flexion inutiles au moins sur l'une des traverses d'extrémité du cadre.The proposed train allows by its asymmetrically extendable frame not to exceed the gauge of the track only where it is necessary, to better register the frame working on a curved section of the track, to limit unnecessary bending forces at least on one of the end crosspieces of the frame.

Sur la figure 1 on peut voir un exemple d'aiguillage ou appareil de voie qui, pour les besoins de dépose et pose a été divisé en trois éléments: l'élément de coeur A, l'élément intermédiaire B et enfin l'élément de lames C. La longueur et la largeur de ces différents éléments sont variables selon l'appareil de voie considéré et également selon leur type, selon s'il s'agit d'un aiguillage simple ou double ou d'une traversée- jonction.In Figure 1 we can see an example of a switch or track device which, for the purposes of removal and installation has been divided into three elements: the core element A, the intermediate element B and finally the element of Blades C. The length and width of these various elements are variable depending on the switchway considered and also according to their type, depending on whether it is a single or double switch or a crossing-junction.

Lorsque l'on veut remplacer un ancien appareil de voie par un nouvel appareil de voie, il est évident que le démontage, comme le montage, ne peut pas s'opérer en une seule fois, c'est pourquoi l'on démonte les éclisses, ou découpe, dans l'exemple considéré, l'ancien appareil de voie selon les trois éléments définis ci-dessus et on les échange avec des éléments de même longueur prémontés en atelier. L'élément de lames C et l'élément intermédiaire B sont montés intégralement en atelier. C'est seulement dans les cas exceptionnels d'aiguillages très longs que, pour tenir compte des dimensions maximum des wagons surbaissés décrits ultérieurement, on enlève les traverses d'extrémité des éléments et on les manipule séparément. L'élément de coeur A est également complètement prémonté, à l'exception des traverses d'extrémités dépassant une longueur déterminée. Ces deux longueurs limites dépendent de la construction et des dimensions des wagons de transport surbaissés, de la largeur maximale du cadre télescopique à travers lequel doit pouvoir être levé et abaissé l'élément de coeur et également du gabarit de voie a respecter.When you want to replace an old switchgear with a new switchgear, it is obvious that disassembly, like assembly, cannot be carried out at once, this is why we dismantle the fishplates , or cutting, in the example considered, the old switchgear according to the three elements defined above and they are exchanged with elements of the same length pre-assembled in the workshop. The blade element C and the intermediate element B are completely assembled in the workshop. It is only in the exceptional cases of very long switches that, to take account of the maximum dimensions of the lowered wagons described later, the end cross members of the elements are removed and they are handled separately. The core element A is also completely pre-assembled, with the exception of end crosspieces exceeding a determined length. These two limit lengths depend on the construction and dimensions of the lowered transport wagons, on the maximum width of the telescopic frame through which it must be possible to raise and lower the core element and also on the gauge of track to be respected.

Pour effectuer cette opération de démontage de montage, et de transport on utilise un train de renouvellement tel qu'illustré figure 2. Ce train comporte un wagon de pose 1, avec cadré vide, supporté par deux boggies 2,3 et qui sera décrit plus en détail ci-après, au moins un wagon de transport du nouveau matériel 4, placé à l'arrière du wagon de pose 1 et au moins un wagon de transport de l'ancien materiel 5, placé à l'avant du wagon de posé ou inversement. Ces deux wagons de transport 4,5 sont surbaissés et permettent de transporter un appareil de voie complet, prémonté en trois éléments. Ils sont munis de deux boggies, d'installation de choc et de traction et d'un frein automatique, ils peuvent être incorporés dans les trains de marchandise. Deux portiques 6,7 peuvent rouler sur des voies de roulement 24 fixées sur le wagon le pose 1 d'une part et sur les wagons de transport 4, 5 d'autre part. Ces portiques 6,7 sont reliés entre eux par une poutre longitunidale 8 munie dé trois paires de potences 9, 9', 9" avec des treuils de levage 23 pour la manutention des éléments à l'aide de câbles 43 et de crochets 34 (fig.1 0).To carry out this assembly disassembly and transport operation, a renewal train is used as illustrated in FIG. 2. This train comprises a laying wagon 1, with an empty frame, supported by two bogies 2,3 and which will be described more in detail below, at least one wagon for transporting the new equipment 4, placed at the rear of the laying wagon 1 and at least one wagon for transporting the old equipment 5, placed at the front of the laying wagon Or vice versa. These two transport wagons 4,5 are lowered and make it possible to transport a complete track device, pre-assembled in three elements. They are equipped with two bogies, shock and traction installation and an automatic brake, they can be incorporated in the freight trains. Two gantries 6,7 can roll on rolling tracks 24 fixed on the wagon the pose 1 on the one hand and on the transport wagons 4, 5 on the other hand. These gantries 6,7 are connected together by a longitudinal beam 8 provided with three pairs of brackets 9, 9 ', 9 "with lifting winches 23 for handling the elements using cables 43 and hooks 34 ( fig. 1 0).

Le wagon de pose 1, selon la figure 3 est formé par le cadre de pose vide comportant deux poutres longitudinales 10, 10' reliées entre elles par deux traverses d'extrémité télescopiques doubles 11, 12.The laying wagon 1, according to FIG. 3, is formed by the empty laying frame comprising two longitudinal beams 10, 10 'connected to each other by two double telescopic end crossmembers 11, 12.

En se référant aux figures 3 à 5, on peut voir que chaque paire de traverses 11, 12 est composée de deux tubes de guidage 13, 13' adjacents, fixés sur le boggie 2 ou 3 par un axe d'articulation commun 15 autour duquél ils peuvent pivoter, chaque tube de guidage 13, 13' étant destiné à recevoir un tube télescopique 14, 14'. Le premier tube télescopique 14 de chaque paire qui coopère avec un des tubes de guidage 13 est fixé à la poutre latérale 10 tandis que l'autre tube télescopique 14' de chaque paire qui coopère avec l'autre tube de guidage 13' est fixe à la poutre latérale 10'. Ainsi les poutres latérales 10, 10' peuvent être déplacées télescopiquement par rapport au châssis du wagon de pose pour élargir le cadre jusqu'à une valeur telle que les éléments de l'appareil de voie anciens ou neufs puissent être levés, respectivement abaissés, à travers ce cadre. La commande de ces traverses télescopiques est effectuée individuellement au moyen de verins hydrauliques non représentés. Ainsi, avec cette disposition, on peut déplacer indépendamment l'une ou l'autre poutre latérale ou les deux ensemble et donc on peut élargir le cadre soit symétriquement c'est-à-dire en conservant le parallélisme des poutres 10, 10' en agrandissant les traverses télescopiques de la même valeur, soit asymétriquement selon le gabarit de l'appareil de voie à manipuler, comme par exemple illustré sur la figure 3, en agissant sur les vérins hydrauliques de la manière appropriée. Pour faciliter l'ouverture et la fermeture du cadre, les poutres longitudinales 10, 10' sont fixées sur les extrémités 14a des éléments télescopiques 14, 14' par sur la figure 3a. En marche haut le pied, pendant la circulation des portiques, les tubes télescopiques 13, 13' sont bloqués entre eux et forment un cadre rigide avec les poutres 10, 10'.With reference to FIGS. 3 to 5, it can be seen that each pair of crosspieces 11, 12 is composed of two adjacent guide tubes 13, 13 ′, fixed to the bogie 2 or 3 by a common articulation axis 15 around which they can pivot, each guide tube 13, 13 'being intended to receive a telescopic tube 14, 14'. The first telescopic tube 14 of each pair which cooperates with one of the guide tubes 13 is fixed to the lateral beam 10 while the other telescopic tube 14 'of each pair which cooperates with the other guide tube 13' is fixed to the side beam 10 '. Thus the lateral beams 10, 10 ′ can be moved telescopically relative to the chassis of the laying wagon to widen the frame to a value such that the elements of the old or new switchgear can be raised and lowered respectively. through this frame. The control of these telescopic sleepers is carried out individually at by means of hydraulic cylinders not shown. Thus, with this arrangement, one or the other lateral beam or both can be moved independently and therefore the frame can be widened either symmetrically, that is to say while preserving the parallelism of the beams 10, 10 'in enlarging the telescopic crosspieces of the same value, either asymmetrically depending on the gauge of the track device to be manipulated, as for example illustrated in FIG. 3, by acting on the hydraulic cylinders in the appropriate manner. To facilitate the opening and closing of the frame, the longitudinal beams 10, 10 'are fixed on the ends 14a of the telescopic elements 14, 14' by in FIG. 3a. When walking high, during the movement of the gantry cranes, the telescopic tubes 13, 13 'are locked together and form a rigid frame with the beams 10, 10'.

Leg boggies 2, 3 sur lesquels s'appuie ce cadre du wagon de pose 1 sont équipés d'installations de choc et de traction ainsi que d'un frein automatique. Un des boggies est muni d'un moteur Diesel qui entraîne une pompe hydraulique pour les différents systèmes de commande du wagon de pose.Leg bogies 2, 3 on which this frame of the laying wagon 1 rests are equipped with shock and traction systems as well as an automatic brake. One of the bogies is fitted with a diesel engine which drives a hydraulic pump for the various control systems of the laying wagon.

Les portiques 6, 7 selon les figures 6 et 7 sont constitués par deux éléments de roulement 20 surmontés de colonnes 21 supportant la voute supérieure 22 laquelle est réglable en hauteur par des vérins hydrauliques. Les deux portiques 6, 7 sont liés entre eux par une poutre longitudinale 8 qui peut se déplacer transversalement par rapport à eux, sur des poutres transversales 31, 32 selon la flèche double F de la figure 8. Sur cette poutre longitudinale 8 sont montées trois paires de potences pivotantes 9, 9' 9" commandées individuellement par des vérins hydrauliques et qui sont équipées chacune, comme déjà mentionné, de leur propre treuil de levage 23 avec câble 43 et crochet 34 (fig.10). L'accrochage de l'élément de l'appareil de voie au treuil est de préférence effectué par l'intermédiaire de palonniers spéciaux facilement adaptables aux différents écartements des appareils de voie. Un exemple de palonnier 33 est illustré figures 10, 11 et 12 sur lesquelles on peut voir un palonnier 33 réglable en longueur et composé de deux parties télescopiques 33, 33a munies de moyens de fixation entre elles et de moyens de suspension 39, 39a aux crochets 34 des câbles 43. Des mâchoires 35 déplaçables longitudinalement et qui peuvent être serrées par un système de vis-écrou 40 sont destinées à agripper les rails 36 de l'élément de voie à transporter.The gantries 6, 7 according to FIGS. 6 and 7 are constituted by two rolling elements 20 surmounted by columns 21 supporting the upper vault 22 which is adjustable in height by hydraulic jacks. The two gantries 6, 7 are linked together by a longitudinal beam 8 which can move transversely with respect to them, on transverse beams 31, 32 according to the double arrow F of FIG. 8. On this longitudinal beam 8 are mounted three pairs of pivoting brackets 9, 9 '9 "individually controlled by hydraulic cylinders and which are each equipped, as already mentioned, with their own lifting winch 23 with cable 43 and hook 34 (fig.10). the element of the track device in the winch is preferably carried out by means of special spreaders easily adaptable to the different spacings of the track devices. An example of a spreader 33 is illustrated in FIGS. 10, 11 and 12 on which a spreader 33 adjustable in length and composed of two telescopic parts 33, 33a provided with means for fixing them and suspension means 39, 39a to the hooks 34 of the cables 43. Jaws 35 movable longitu linearly and which can be tightened by a screw-nut system 40 are intended to grip the rails 36 of the track element to be transported.

Sur la figure 9 on peut voir les grandes possibilités offertes par le système de levage qui permet de soulever, pivoter, transporter l'élément à poser ou déposer grâce à la commande indépendante des treuils de levage 23 et au déplacement transversal de la poutre longitudinale 8 dans les portiques 6, 7. Les traverses seules peuvent être également posées ou déposées à l'aide du système de levage des portiques muni à cet effet d'une poutre de pose permettant le transport simultané de plusieurs traverses.In FIG. 9 we can see the great possibilities offered by the lifting system which makes it possible to lift, pivot, transport the element to be placed or deposited thanks to the independent control of the lifting winches 23 and to the transverse displacement of the longitudinal beam 8 in gantries 6, 7. The sleepers alone can also be laid or removed using the gantry lifting system fitted for this purpose with a laying beam allowing the simultaneous transport of several sleepers.

Chaque portique est équipé d'un moteur Diesel qui entraîne des pompes hydrauliques pour le système de traction, pour le système se chariotage transversal de la poutre longitudinale 8 sur les poutres transversales 31, 32 pour la commande hydraulique des potences 9, 9', 9" et des treuils de levage 23.Each gantry is equipped with a diesel engine which drives hydraulic pumps for the traction system, for the system of transverse carriage of the longitudinal beam 8 on the transverse beams 31, 32 for the hydraulic control of the brackets 9, 9 ', 9 "and lifting winches 23.

Lors de l'échange des appareils de voie, on procède de la manière suivante: avant l'arrivée du train de renouvellement sur le chantier, l'ancien appareil de voie doit être démonté en démontant les éclisses ou éventuellement en coupant les rails en trois parties de longueurs égales à celles du nouvel appareil et, si nécessaire, on déboulonne les traverses d'extrémité dont la longueur dépasse le gabarit admis. Le train de renouvellement est ensuite amené sur le chantier pour la dépose de l'ancien appareil de voie et la pose du nouveau. Cet échange peut être effectué pièce par pièce c'est-à-dire qu'un ancien élément déposé est immédiatement remplacé par un nouvel élément sans déplacement du wagon de pose seuls les portiques 6, 7 se déplaçant sur les voies de roulement 24 une première fois selon la flèche D (fig.2) après la dépose de l'ancien élément et une seconde fois selon la flèche P pour la pose du nouvel élément.When exchanging the switchgear, the procedure is as follows: before the renewal train arrives on site, the old switchgear must be dismantled by dismantling the fishplates or possibly cutting the rails in three parts of length equal to those of the new device and, if necessary, the end crossbars are unbolted, the length of which exceeds the allowed gauge. The renewal train is then brought to the site for the removal of the old switch and the installation of the new one. This exchange can be carried out piece by piece, that is to say that an old deposited element is immediately replaced by a new element without moving the laying wagon only the gantry cranes 6, 7 moving on the tracks 24 a first times according to arrow D (fig. 2) after removing the old element and a second time according to arrow P for installing the new element.

Dans le cas où l'on désire combiner le travail de remplacement des appareils de voie avec celui de criblage du ballast ou, le cas échéant, assainissement de la plate-forme, on applique de préférence un second procédé qui consiste à déposer un premier élément, à le remplacer par un élément de voie auxiliaire de même longueur 37, comme illustré fig.3, à déplacer le wagon de pose pour déposer le second élément et le remplacer par un autre élément de voie auxiliaire, ainsi de suite. Puis on procède aux travaux d'assainissement désirés de la plate-forme à l'aide de machines connues.In the case where it is desired to combine the work of replacing the track equipment with that of screening the ballast or, if necessary, cleaning up the platform, a second method is preferably applied which consists in depositing a first element , to replace it with an auxiliary track element of the same length 37, as illustrated in fig.3, to move the laying wagon to deposit the second element and replace it with another auxiliary track element, and so on. Then we proceed to the desired remediation works of the platform using known machines.

Enfin, on remplace le premier élément de voie auxiliaire par le premier élément de voie neuf, etc.Finally, the first auxiliary track element is replaced by the first new track element, etc.

On peut commencer l'echange des éléments de l'appareil de voie goit avec l'élément de coeur A, soit avec l'élément de lames C. Les trois éléments sont remplacés à l'aide des portiques de la manière suivante: les portiques 6, 7 sont manoeuvrés sur la voie de roulement jusqu'à ce qu'ils occupent la position illustrée figure 6, c'est-à-dire qu'ils se trouvent de part et d'autre du wagon de pose 1. On écarte les poutres latérales 10,10' du wagon de pose 1 jusqu'à ce que l'élément de l'appareil de voie puisse passer à travers le cadre. A cet effet, les traverses télescopiques 11, 12 sont actionnées jusqu'à ce que le cadre occupe la position voulue. On accroche l'élément de voie aux treuils par l'intermédiaire de palonniers 33 et on soulève ledit élément jusqu'à ce qu'il ait traversé le wagon cadre 1. On replace les poutres latérales 10, 10' dans leur position initiale et l'on bloque les traverses télescopiques dans la position fermée de manière à permettre aux portiques 6, 7 de se déplacer selon la flèche D de la figure 2 sur le chemin de roulement 24 pour transporter l'élément démonté sur le wagon de transport de l'ancien matériel 5. Pendant ce temps, le ballast peut être égalisé avec une herse à ballast. Ensuite, l'ensemble portiques 6, 7 et poutre longitudinale 8 est déplacé vers l'arrière pour soulever et transporter selon la flèche P de la figure 2 l'élément neuf, lequel est manoeuvre par les treuils de la manière illustrée en traits mixtes sur la figure 11. Cet élément neuf, qui a été préalablement monté en atelier, est éventuellement dépourvu de ses traverses d'extrémité si sa longueur excède la longueur de la partie surbaissée du wagon de transport. Dans ce cas, les traverses isolées sont posées avec les portiques avant l'élément de l'appareil de voie.We can start exchanging the elements of the goit track device with the core element A, or with the blade element C. The three elements are replaced using the gantries as follows: the gantries 6, 7 are maneuvered on the track until they occupy the position illustrated in FIG. 6, that is to say that they are on either side of the laying wagon 1. We move aside the side beams 10,10 'of the laying wagon 1 until the element of the track device can pass through the frame. For this purpose, the telescopic crosspieces 11, 12 are actuated until the frame occupies the desired position. The track element is hooked to the winches via spreaders 33 and the said element is lifted until it has passed through the frame wagon 1. The lateral beams are replaced 10, 10 'in their initial position and the telescopic cross members are blocked in the closed position so as to allow the gantries 6, 7 to move according to the arrow D in FIG. 2 on the raceway 24 to transport the element disassembled on the transport wagon of old equipment 5. Meanwhile, the ballast can be leveled with a ballast harrow. Then, the set of gantries 6, 7 and longitudinal beam 8 is moved rearward to lift and transport according to arrow P in FIG. 2 the new element, which is operated by the winches in the manner illustrated in dashed lines on Figure 11. This new element, which has been previously assembled in the workshop, is possibly devoid of its end crosspieces if its length exceeds the length of the lowered part of the transport wagon. In this case, the insulated sleepers are laid with the gantries before the element of the switchgear.

Sur la figure 8 on peut voir, d'une manière schématique, montrant seulement la silhouette des éléments comprenant rails et traverses, comment ceux-ci sont rangés, après manipulation, dans le wagon de transport 4 surbaissé; les éléments sont calés à l'aide d'une barre articulée 25 et d'un levier 26. Les voutes 22 des portiques 6, 7 sont réglées en hauteur pour permettre le passage des éléments d'appareil de voie. Des cales 27 montées dans le fond du wagon de transport 4 assurent un bon positionnement des éléments. Comme déjà signalé, les traverses d'extrémité des éléments dépassant la longueur de la partie surbaissée du wagon ne sont pas montées en atelier, mais seulement sur le chantier, ceci afin de reduire l'encombrement des éléments dans le wagon illustré figure 7.In Figure 8 we can see, schematically, showing only the silhouette of the elements comprising rails and sleepers, how they are stored, after handling, in the transport wagon 4 lowered; the elements are wedged using an articulated bar 25 and a lever 26. The arches 22 of the gantry cranes 6, 7 are adjusted in height to allow the passage of the switchgear elements. Wedges 27 mounted in the bottom of the transport wagon 4 ensure good positioning of the elements. As already indicated, the end crosspieces of the elements exceeding the length of the lowered part of the wagon are not assembled in the workshop, but only on the site, this in order to reduce the bulk of the elements in the wagon illustrated in FIG. 7.

L'invention n'est pas limitée à l'exemple décrit notamment en ce qui concerne le choix du nombre d'éléments constituant l'appareil de voie. On pourrait, par exemple pour les aiguillages de moindre longueur, réduire le nombre d'éléments à deux, c'est-à-dire supprimer l'élément intermédiaire ou, pour les aiguillages très longs, prévoir plus de trois éléments lors du prémontage en atelier et de la découpe de l'ancien appareil de voie.The invention is not limited to the example described in particular as regards the choice of the number of elements constituting the switchgear. One could, for example for shorter switches, reduce the number of elements to two, that is to say remove the intermediate element or, for very long switches, provide more than three elements during pre-assembly in workshop and cutting of the old switchgear.
