The concave part provides a region for access around the butt ends. Each support plate is provided with a retaining clamp which is provided with a jaw able to bear against the opposite vertical side of the head of the rail. The device can be applied to the welding of rails on a track or on a fixed installation.

Description

La présente invention concerne un dispositif de réglage et de maintien de deux abouts de rails à raccorder par soudure.The present invention relates to a device for adjusting and holding two end pieces of rails to be connected by welding.

Dans les opérations de raccordement de deux abouts de rails, en particulier de rails de chemin de fer, il faut procéder à un réglage des rails avant leur raccordement par soudure.In the operations of connecting two ends of rails, in particular railway rails, the rails must be adjusted before they are connected by welding.

Ce réglage consiste à régler la distance intercalaire entre les deux abouts de rails à raccorder, à aligner les côtés verticaux intérieurs des champignons des rails à raccorder et à relever légèrement les abouts vers le haut.This adjustment consists of adjusting the intermediate distance between the two ends of the rails to be connected, aligning the internal vertical sides of the mushrooms of the rails to be connected and slightly lifting the ends up.

Ces opérations de réglage se font soit à la main au moyen de cales appropriées, soit au moyen de machines plus ou moins sophistiquées.These adjustment operations are carried out either by hand by means of suitable shims, or by more or less sophisticated machines.

Les dispositifs connus comportent des presses munies de machoires aptes à venir en appui sur les côtés de l'âme du rail (DE-C-219 944 et FR-A-1 585 696).The known devices include presses fitted with jaws capable of coming to bear on the sides of the rail core (DE-C-219 944 and FR-A-1 585 696).

La présente invention vise à réaliser un dispositif de construction beaucoup plus simple que les machines existant actuellement en vue d'obtenir un réglage semi-manuel des rails à raccorder par soudure. A cette fin, l'invention concerne un dispositif qui permet de régler l'alignement des côtés verticaux intérieurs des champignons des rails, l'opération de réglage de distance intercalaire étant effectuée au préalable, et l'opération de relevage des abouts étant effectuée ensuite soit manuellement au moyen d'un jeu de cales appropriées, soit au moyen de vérins à vis ou hydrauliques.The present invention aims to achieve a much simpler construction device than the machines currently existing in order to obtain a semi-manual adjustment of the rails to be connected by welding. To this end, the invention relates to a device which makes it possible to adjust the alignment of the interior vertical sides of the rail mushrooms, the operation of adjusting the intermediate distance being carried out beforehand, and the operation of lifting the ends being carried out subsequently. either manually by means of a set of suitable shims, or by means of screw or hydraulic cylinders.

Plus précisément, le dispositif de l'invention comprend une structure rigide qui est formée de deux plaques d'appui alignées et reliées entre elles par une partie incurvée et qui est susceptible d'être disposée horizontalement en sorte que les deux plaques d'appui soient appliquées l'une sur un côté vertical du champignon de l'un des rails et l'autre sur le côté vertical du champignon de l'un des rails et l'autre sur le côté vertical correspondant du champignon de l'autre rail, la partie incurvée ménageant une zone d'accès autour des abouts, chaque plaque d'appui étant pourvue d'une presse de maintien munie d'une mâchoire apte à venir en appui sur le côté vertical opposé du champignon du rail.More specifically, the device of the invention comprises a rigid structure which is formed of two support plates aligned and connected to each other by a curved part and which is capable of being arranged horizontally so that the two support plates are applied one on one vertical side of the head of one of the rails and the other on the vertical side of the head of one of the rails and the other on the corresponding vertical side of the head of the other rail, the curved part providing an access zone around the ends, each support plate being provided with a holding press provided with a jaw capable of coming to bear on the opposite vertical side of the rail head.

Dans un mode de réalisation préférentiel du dispositif de l'invention, les deux plaques d'appui sont pourvues chacune de deux appuis espacés de manière à former quatre appuis espacés constituant une ligne de référence pour l'alignement des rails et chaque presse de maintien est située sensiblement à égale distance entre les deux appuis de la plaque d'appui correspondante.In a preferred embodiment of the device of the invention, the two support plates are each provided with two spaced supports so as to form four spaced supports constituting a reference line for the alignment of the rails and each holding press is located substantially at equal distance between the two supports of the corresponding support plate.

L'écart entre les deux presses de maintien permet alors de placer sur le dessus des champignons des rails une règle pour vérifier le bon relevage des abouts. En outre la zone d'accès ménagée autour des abouts par la partie incurvée du dispositif permet d'appliquer une règle sur le côté vertical intérieur des champignons des deux rails pour vérifier le bon alignement vertical de ces côtés.The distance between the two holding presses then allows a ruler to be placed on top of the rail mushrooms to check that the ends are properly lifted. In addition, the access zone formed around the butt ends by the curved part of the device makes it possible to apply a rule on the internal vertical side of the mushrooms of the two rails to verify the correct vertical alignment of these sides.

Il en résulte qu'après serrage des deux presses de maintien, l'alignement des côtés verticaux des champignons des deux rails est automatiquement réalisé grâce aux quatre appuis précités, le réglage de la distance intercalaire ayant été réalise au préalable.As a result, after tightening of the two holding presses, the vertical sides of the mushrooms of the two rails are aligned automatically by means of the four aforementioned supports, the adjustment of the intermediate distance having been carried out beforehand.

Pour permettre d'effectuer en plus de l'opération de réglage des côtés verticaux des champignons des rails, une opération de réglage d'alignement des patins de rails, chaque plaque d'appui est pourvue d'un bloc d'ancrage apte à recevoir une presse de réglage de l'alignement des patins de rails. Cette presse est munie d'une mâchoire susceptible de prendre appui sur l'extrémité du patin du rail dont il convient de modifier le dévers pour que les deux patins de rails soient alignés.To make it possible to carry out, in addition to the operation for adjusting the vertical sides of the rail mushrooms, an operation for adjusting the alignment of the rail pads, each support plate is provided with an anchoring block capable of receiving a press for adjusting the alignment of the rail pads. This press is provided with a jaw capable of bearing on the end of the rail pad, the slope of which should be modified so that the two rail pads are aligned.

La structure du dispositif de l'invention est munie avantageusement d'un porte-creuset apte à recevoir un creuset aluminothermique pour la soudure des rails.The structure of the device of the invention is advantageously provided with a crucible holder capable of receiving an aluminothermic crucible for welding the rails.

Selon une autre particularité du dispositif de réglage de l'invention, celui-ci peut être utilisé pour des soudures sur place ou pour des soudures en poste fixe.According to another particular feature of the adjustment device of the invention, it can be used for spot welding or for welding in a fixed position.

Dans le premier cas, le dispositif de réglage sera avantageusement transporté sur le lieu de soudure au moyen d'un chariot approprié, alors que dans le second cas le dispositif de réglage sera solidiaire d'une installation fixe.In the first case, the adjustment device will advantageously be transported to the place of welding by means of an appropriate trolley, while in the second case the adjustment device will be of a fixed installation.

Le chariot mobile utilisé pour le transport du dispositif de réglage peut être par exemple constitué par un chariot à deux roues du type diable comportant deux supports aptes à recevoir de façon amovible le dispositif de réglage disposé à l'horizontale. Un tel chariot convient tout particulièrement au transport du dispositif de réglage en vue de réaliser des soudures sur des chaussées, par exemple des soudures de rails de tramway.The mobile carriage used for transporting the adjustment device can for example be constituted by a two-wheeled cart of the devil type comprising two supports capable of detachably receiving the adjustment device arranged horizontally. Such a carriage is particularly suitable for transporting the adjusting device in order to carry out welds on roadways, for example welds on tram rails.

Le chariot peut être également constitué par un chariot automoteur du type lorry déplaçable sur voie ferrée et comportant au moins un dispositif de réglage porté par un bras articulé.The trolley can also be constituted by a self-propelled trolley of the lorry type which can be moved on a railway track and comprising at least one adjustment device carried by an articulated arm.

Ce chariot sera muni d'un moteur d'entraînement et d'une source de puissance appropriée et il pourra en outre avantageusement constituer un moyen de transport pour le matériel de soudure, c'est-à-dire les matières consommables pour réaliser les soudures, des outils alimentés ou non par la source de puissance et servant par exemple au tronçonnage des rails, à l'ébavurage des soudures, au meulage des soudures, etc.This carriage will be provided with a drive motor and an appropriate power source and it may further advantageously constitute a means of transport for the welding equipment, that is to say the consumable materials for performing the welds. , tools powered or not by the power source and used for example for cutting rails, deburring welds, grinding welds, etc.

En outre, ce chariot sera avantageusement déraillable, c'est-à-dire muni de moyens pour le déplacer latéralement hors de la voie ferrée pour permettre, le cas échéant, le passage d'un train sur la voie entre deux opérations de soudure.In addition, this carriage will advantageously be derailable, that is to say provided with means for moving it laterally out of the track for allow, if necessary, the passage of a train on the track between two welding operations.

Dans un chariot de ce type, il sera préférable de prévoir au moins deux dispositifs de réglage disposés de façon amovible de manière à permettre d'effectuer deux opérations de réglage simultanées, une sur chaque file de rail.In a carriage of this type, it will be preferable to provide at least two adjustment devices arranged in a removable manner so as to allow two simultaneous adjustment operations to be carried out, one on each rail file.

Lorsque le dispositif de réglage de l'invention est utilisé sur une installation fixe, celui-ci est monté pivotant autour d'un axe horizontal du bâti de l'installation, parallèlement à la direction d'alignement des plaques d'appui, c'est-à-dire parallèlement à la direction d'alignement des rails. Dans une telle installation, les rails sont amenés et évacués au moyen de rouleaux et d'un dispositif de traction approprié.When the adjustment device of the invention is used on a fixed installation, it is pivotally mounted about a horizontal axis of the frame of the installation, parallel to the direction of alignment of the support plates, it that is to say parallel to the direction of alignment of the rails. In such an installation, the rails are brought in and removed by means of rollers and an appropriate traction device.

Dans une telle installation, les blocs d'ancrage destinés à recevoir la presse de réglage de dévers et le porte-creuset sont avantageusement prévus sur le bâti de l'installation au lieu d'être prévus sur la structure du dispositif comme indiqué précédemment dans le cas des dispositifs portés sur chariot.In such an installation, the anchoring blocks intended to receive the tilt adjustment press and the crucible holder are advantageously provided on the frame of the installation instead of being provided on the structure of the device as indicated previously in the case of devices carried on a trolley.

On a représenté sur la figure 1 un dispositif de réglage 10 selon l'invention mis en place sur deux rails 12 et 14 qu'il convient de régler. Le dispositif 10 est constitué par une structure rigide formée d'une tôle d'acier de forte épaisseur par exemple de 15 mm d'épaisseur. Cette structure affecte la forme d'une partie incurvée 16 en forme de U se terminant par deux plaques d'appui 18 et 20 pourvues de deux tranches respectives 22 et 24. La plaque d'appui 18 est pourvue de deux appuis 26 et 28 solidaires de la tranche 22 et destinés à être appliqués sur le côté vertical 30 du champignon du rail 12. De même, la plaque d'appui 20 est pourvue de deux appuis 3.2 et 34 solidaires de la tranche 24 et destinés à être appliqués sur le côté vertical 36 du champignon du rail 14. Les appuis 26, 28, 32 et 34 sont alignés de manière à constituer une ligne de référence pour l'alignement des côtés 30 et 36 des champignons des rails 12 et 14.There is shown in Figure 1 an adjustment device 10 according to the invention placed on two rails 12 and 14 that should be adjusted. The device 10 consists of a rigid structure formed from a sheet of very thick steel, for example 15 mm thick. This structure assumes the shape of a curved portion 16 in the shape of a U ending in two support plates 18 and 20 provided with two respective edges 22 and 24. The support plate 18 is provided with two supports 26 and 28 integral of the section 22 and intended to be applied to the vertical side 30 of the head of the rail 12. Similarly, the support plate 20 is provided with two supports 3.2 and 34 integral with the section 24 and intended to be applied on the side vertical 36 of the head of the rail 14. The supports 26, 28, 32 and 34 are aligned so as to constitute a reference line for the alignment of the sides 30 and 36 of the mushrooms of the rails 12 and 14.

Les appuis 28 et 32 sont disposés à proximité immédiate de la partie incurvée 16 qui définit une zone d'accès autour des deux abouts 38 et 40 à régler et à souder. L'écart entre les appuis 28 et 32 est déterminé de manière à pouvoir placer une régle, par exemple de 0,50 m de longueur, pour vérifier le bon alignement des côtés verticaux 30 et 36 des rails 12 et 14. Le dispositif 10 peut être renforcé à sa partie inférieure par une tôle pliée 45.The supports 28 and 32 are arranged in the immediate vicinity of the curved part 16 which defines an access area around the two ends 38 and 40 to be adjusted and welded. The distance between the supports 28 and 32 is determined so as to be able to place a rule, for example 0.50 m in length, to check the correct alignment of the vertical sides 30 and 36 of the rails 12 and 14. The device 10 can be reinforced at its lower part by a folded sheet 45.

Le dispositif de réglage 10 est en outre pourvu de deux presses de maintien 42 et 44 situées sensiblement à égale distance entre respectivement les appuis 26 et 28 d'une part et les appuis 32 et 34 d'autre part. L'écart entre les deux presses 42 et 44 permet de placer sur le dessus des champignons des rails 12 et 14 une règle, par exemple de 1 m de longueur, pour vérifier le bon relevage des abouts. Ces deux presses 42 et 44 sont identiques et l'on décrira ci-après la presse 44 en référence aux figures 1 et 3.The adjusting device 10 is further provided with two holding presses 42 and 44 located substantially at equal distance between the supports 26 and 28 respectively on the one hand and the supports 32 and 34 on the other hand. The distance between the two presses 42 and 44 makes it possible to place a ruler, for example 1 m in length, on the top of the rails 12 and 14 mushrooms, to check that the ends are properly lifted. These two presses 42 and 44 are identical and the press 44 will be described below with reference to FIGS. 1 and 3.

Comme représenté sur la figure 3, la presse 44 est pourvue d'une mâchoire fixe 46 fixée sur la tranche 24 de la plaque d'appui 20 de manière à être alignée avec les appuis 32 et 34. La presse 44 est par ailleurs pourvue d'un support 48 de section en forme de U, dont une extrémité 50 est solidaire de la plaque d'appui 20 et dont l'autre extrémité 52 est solidaire d'un bloc 54 fileté intérieurement. Ce bloc 54 sert au passage d'une tige filetée 56 dont une extrémité est pourvue d'une mâchoire 58 montée à rotation libre et constituant la mâchoire mobile de la presse 44 et dont l'autre extrémité est pourvue d'une manette de commande 60.As shown in FIG. 3, the press 44 is provided with a fixed jaw 46 fixed on the edge 24 of the support plate 20 so as to be aligned with the supports 32 and 34. The press 44 is moreover provided with 'A support 48 of U-shaped section, one end 50 of which is integral with the support plate 20 and the other end 52 of which is integral with a block 54 internally threaded. This block 54 is used for the passage of a threaded rod 56, one end of which is provided with a jaw 58 mounted for free rotation and constituting the movable jaw of the press 44 and the other end of which is provided with a control handle 60 .

Le support 48 est par ailleurs pourvu sur sa face inférieure, dans la portion comprise entre ses extrémités 50 et 52, d'un appui 62 destiné à venir coopérer avec le dessus du champignon du rail 14.The support 48 is also provided on its lower face, in the portion between its ends 50 and 52, with a support 62 intended to come to cooperate with the top of the head of the rail 14.

Comme représenté sur la figure 3, la presse 44 peut s'adapter aussi bien à un rail 14 des faibles dimensions qu'à un rail 14' de plus grandes dimensions.As shown in FIG. 3, the press 44 can be adapted to a rail 14 of small dimensions as well as to a rail 14 'of larger dimensions.

Le dispositif 10 est en outre pourvu de deux poignées 64 et 66 destinées à faciliter son transport et de deux pieds escamotables et réglables 68 et 70 destinés à maintenir le dispositif à l'horizontale.The device 10 is further provided with two handles 64 and 66 intended to facilitate its transport and with two retractable and adjustable feet 68 and 70 intended to keep the device horizontal.

Les presses de maintien 42 et 44 permettent d'assurer le réglage de l'alignement des côtés verticaux des champignons des rails 12 et 14. Pour permettre de régler en plus l'alignement des patins, ou semelles, des rails 12 et 14, le dispositif 10 est muni de deux blocs d'ancrage 72 et 74 prévus à proximité des appuis 28 et 32. Ces blocs peuvent recevoir de façon amovible une presse de réglage 76 qui sera expliquée plus particulièrement en référence à la figure 4. Sur les figures 1, 2 et 4, la presse 76 est représentée ancrée sur le bloc 72, mais celle-ci peut être aussi bien ancrée sur le bloc 74 en fonction de la disposition relative des patins des rails 12 et 14.The holding presses 42 and 44 make it possible to adjust the alignment of the vertical sides of the mushrooms of the rails 12 and 14. In order to allow the alignment of the pads, or soles, of the rails 12 and 14 to be adjusted, the device 10 is provided with two anchoring blocks 72 and 74 provided near the supports 28 and 32. These blocks can detachably receive an adjustment press 76 which will be explained more particularly with reference to FIG. 4. In FIGS. 1 , 2 and 4, the press 76 is shown anchored on the block 72, but it can also be anchored on the block 74 depending on the relative arrangement of the pads of the rails 12 and 14.

La presse 76 comporte un bras 78 susceptible d'être ancré sur le bloc 72 ou sur le bloc 74 avec possibilité de pivotement et pourvu à son extrémité libre d'un prolongement coudé 80. Le prolongement 80 se termine par un fourreau 82 fileté intérieurement pour recevoir une tige filetée 84 dont une extrémité est pourvue d'une mâchoire 86 montée librement et dont l'autre extrémité est pourvue d'un levier 88 destiné à assurer l'entraînement de la tige filetée 84 et par suite le déplacement de la mâchoire 86. Comme représenté sur la figure 4, la mâchoire 86 vient en appui sur l'extrémité extérieure du patin d'un rail 14 de petites dimensions. Cette mâchoire peut occuper une position 86' pour venir en appui sur l'extrémité extérieure du patin d'un rail 14' de plus grandes dimensions, le prolongement coudé 80 occupant alors une position angulaire 80' différente (cf. figure 2).The press 76 comprises an arm 78 capable of being anchored on the block 72 or on the block 74 with the possibility of pivoting and provided at its free end with a bent extension 80. The extension 80 ends in a sheath 82 internally threaded for receive a threaded rod 84, one end of which is provided with a freely mounted jaw 86 and the other end of which is provided with a lever 88 intended to drive the threaded rod 84 and consequently the displacement of the jaw 86 As shown in Figure 4, the jaw 86 comes to bear on the outer end of the shoe of a rail 14 of small dimensions. This jaw can occupy a position 86 ′ to come to bear on the outer end of the shoe of a rail 14 ′ of larger dimensions, the bent extension 80 then occupying a different angular position 80 ′ (cf. FIG. 2).

Le dispositif de réglage 10 est par ailleurs pourvu à ses deux extrémités de deux blocs de fixation 90 et 92 destinés le cas échéant à la solidarisation du dispositif de réglage avec un chariot de transport du type lorry, comme cela sera expliqué plus loin en référence à la figure 6.The adjustment device 10 is moreover provided at its two ends with two fixing blocks 90 and 92 intended, where appropriate, for securing the adjustment device with a lorry-type transport carriage, as will be explained below with reference to Figure 6.

Le dispositif 10 est par ailleurs muni d'un creuset aluminothermique 94 porté par une colonne 96 pivotante et réglable en hauteur, dont la base est fixée sur le dispositif de réglage lui-même. Des poignées de manutention 98, 100 et 102 sont prévues pour déplacer le creuset et l'amener au-dessus de l'intervalle entre les deux abouts 38 et 40, comme représenté sur les figures 1 et 2.The device 10 is moreover provided with an aluminothermic crucible 94 carried by a pivoting column 96 which is adjustable in height, the base of which is fixed to the adjustment device itself. Handles 98, 100 and 102 are provided to move the crucible and bring it above the gap between the two ends 38 and 40, as shown in FIGS. 1 and 2.

Le dispositif représenté sur les figures 1 à 4 s'utilise de la manière suivante.The device shown in Figures 1 to 4 is used as follows.

Après avoir procédé au préalable au réglage de la distance intercalaire entre les deux abouts 38 et 40 à souder par un procédé approprié connu en soi, on amène le dispositif en position comme représenté sur les figures 1 et 2. On effectue alors un serrage provisoire des presses 42 et 44 de manière à maintenir le dispositif en position et à aligner les côtés verticaux intérieurs des champignons des deux rails. On relève alors légèrement les deux abouts à souder en utilisant les cales appropriées ou des vérins à vis ou hydrauliques de manière à conférer un "pointu" aux rails. On vérifie alors à l'aide d'une régie que l'alignement des côtés intérieurs des champignons des rails est correct et on vérifie à l'aide d'une autre règle placée sur le dessus des champignons des rails entre les presses 42 et 44 que le "pointu" des rails est correct.After having previously adjusted the intermediate distance between the two ends 38 and 40 to be welded by an appropriate method known per se, the device is brought into position as shown in FIGS. 1 and 2. A temporary tightening of the presses 42 and 44 so as to maintain the device in position and to align the internal vertical sides of the mushrooms of the two rails. The two butt ends to be welded are then slightly raised using the appropriate shims or screw or hydraulic jacks so as to give the rails a "sharp". We then check with the help of a control room that the alignment of the inner sides of the rail mushrooms is correct and we check with another rule placed on top of the rail mushrooms between the presses 42 and 44 that the "point" of the rails is correct.

Si l'alignement des patins des deux rails n'est pas correct, on utilise la presse 76 que l'on fixe sur le bloc d'ancrage approprié, c'est-à-dire celui correspondant au rail dont le patin est le plus écarté par rapport au dispositif. A l'aide de la manette 88 on déplace la mâchoire 86 pour amener progressivement le patin du rail correspondant en alignement avec le patin de l'autre rail. On bloque alors les deux rails en serrant complètement les deux presses 42 et 44. On peut alors procéder au soudage des rails en utilisant le creuset aluminothermique 94 puis à l'élimination de l'excédent de soudure au moyen d'une ébaveureuse appropriée.If the alignment of the pads of the two rails is not correct, use the press 76 which is fixed on the appropriate anchoring block, that is to say that corresponding to the rail whose pad is the most moved away from the device. Using the lever 88, the jaw 86 is moved to gradually bring the pad of the corresponding rail into alignment with the pad of the other rail. The two rails are then blocked by completely tightening the two presses 42 and 44. It is then possible to weld the rails using the aluminotherm crucible 94 and then to eliminate the excess weld by means of an appropriate deburring machine.

Comme indiqué précédemment, le dispositif des figures 1 à 4 peut être transporté sur le lieu de soudure au moyen d'un chariot approprié.As indicated above, the device in FIGS. 1 to 4 can be transported to the place of welding by means of an appropriate trolley.

On a représenté sur la figure 5 un chariot 104 à deux roues du type diable muni de deux supports 106 et 108 aptes à recevoir, de façon amovible, le dispositif de réglage 10 disposé à l'horizontale. Les supports 106 et 108 sont identiques et découpés de manière à constituer respectivement des appuis inférieurs rectilignes 110 et 112 et des évidements 114 et 116 ayant une ouverture légèrement supérieure à l'épaisseur de la tôle constituant le dispositif 10, de manière à tenir le dispositif 10 par simple effet de porte-à-faux.FIG. 5 shows a carriage 104 with two wheels of the devil type provided with two supports 106 and 108 capable of receiving, in a removable manner, the adjustment device 10 arranged horizontally. The supports 106 and 108 are identical and cut so as to constitute respectively rectilinear lower supports 110 and 112 and recesses 114 and 116 having an opening slightly greater than the thickness of the sheet metal constituting the device 10, so as to hold the device 10 by simple cantilever effect.

Un tel chariot 104 convient plus particulièrement au transport du dispositif de réglage pour l'amener sur le lieu de soudure dans le cas où les rails sont disposés sur des chaussées, comme dans le cas des rails de tramway.Such a carriage 104 is more particularly suitable for transporting the adjustment device to bring it to the place of welding in the case where the rails are arranged on roadways, as in the case of tram rails.

On a représenté sur la figure 6 un chariot automoteur 118, du type lorry, déplaçable sur voie ferrée. Ce chariot 118 est constitué par un caisson 120 équipé de quatre roues telles 122 et 124 et d'une source de puissance (non représentée) destinée à alimenter un moteur d'entraînement des roues telles 124.There is shown in Figure 6 a self-propelled carriage 118, of the lorry type, movable on railroad tracks. This carriage 118 consists of a box 120 equipped with four wheels such as 122 and 124 and a power source (not shown) intended to supply a motor for driving the wheels such as 124.

Le chariot 118 est pourvu de deux dispositifs de réglage 126 et 128 analogues au dispositif 10 décrit précédemment, portés respectivement par des bras articulés 130 et 132 prévus à chacune des extrémités du chariot. Sur la figure 6, le dispositif 126 est représenté à l'horizontale en position de transport en appui sur des supports 134 et 136 solidaires du caisson 120 alors que le dispositif 128 est représenté en position d'utilisation, c'est-à-dire à l'horizontale au niveau des rails à régler. Les positions intermédiaires 128' et 128" représentent le dispositif en position de déplacement entre deux opérations de soudure, le creuset aluminothermique restant sur le dispositif. Le bras 130 est articulé autour d'un axe horizontal 138 solidaire du caisson 120 et est muni à son extrémité libre d'une chappe 140 destinée à recevoir de façon amovible le dispositif 126 au moyen d'une goupille détachable 142 passant au travers de l'un des blocs de fixation 144 prévus aux deux extrémités du dispositif 126. Le bras 132 est réalisé de façon analogue au bras 130.The carriage 118 is provided with two adjustment devices 126 and 128 similar to the device 10 described above, carried respectively by articulated arms 130 and 132 provided at each end of the carriage. In FIG. 6, the device 126 is shown horizontally in the transport position bearing on supports 134 and 136 integral with the box 120 while the device 128 is shown in the use position, that is to say at the horizontal at the level of the rails to be adjusted. The intermediate positions 128 ′ and 128 "represent the device in the displacement position between two welding operations, the aluminotherm crucible remaining on the device. The arm 130 is articulated around a horizontal axis 138 secured to the box 120 and is provided at its free end of a cap 140 intended to removably receive the device 126 by means of a detachable pin 142 passing through one of the fixing blocks 144 provided at the two ends of the device 126. The arm 132 is made of analogous to arm 130.

Les dispositifs de réglage 126 et 128 sont amenés sur le lieu de soudure au moyen du chariot 118 et peuvent être ensuite détachés du chariot 118 si les deux soudures à réaliser ne sont pas en parfait vis-à-vis pour permettre d'effectuer deux opérations de réglage simul-. tanées.The adjustment devices 126 and 128 are brought to the place of welding by means of the carriage 118 and can then be detached from the carriage 118 if the two welds to be produced are not in perfect opposite to allow two operations to be carried out simulated adjustment. tanned.

Le caisson 120 du chariot constitue également un moyen de transport pour le matériel destiné au soudage des rails, comme par exemple un creuset aluminothermique, les matériaux nécessaires à la soudure aluminothermique, des cales de réglage, des outils, alimentés ou non par la source de puissance du chariot. Ainsi, cette source de puissance pourra servir à alimenter, par exemple hydraulique- ment, des outils de tronçonnage de rails, des outils d'ébavurage de soudure, des outils de meulage, etc.The box 120 of the carriage also constitutes a means of transport for the material intended for welding the rails, such as for example an aluminothermic crucible, the materials necessary for the aluminothermic welding, shims for adjustment, tools, powered or not by the source of carriage power. Thus, this power source can be used to supply, for example hydraulically, rail cutting tools, welding deburring tools, grinding tools, etc.

Le chariot 118 est en outre pourvu de quatre roues escamotables, telles 146 et 148, portées par des bras, tels 150 et 152, solidaires d'un pivot, tel 154, dirigé dans le sens longitudinal, du chariot, c'est-à-dire parallèlement à sa direction d'avancement. Ces roues 146 et 148 peuvent être amenées par des moyens appropriés (non représentés) dans une position pour faire dérailler le chariot, c'est-à-dire le déplacer transversalement et lui faire quitter les rails sur lesquelles il se déplace pour permettre par exemple le passage d'un train entre deux opérations de réglage. Pour réaliser cette opération de déraillage, il faut également placer des tronçons de rails d'une part entre les deux rails de la voie, perpendiculairement à la direction de la voie et d'autra part du côté extérieur de la voie vers lequel on désire déplacer le chariot.The carriage 118 is further provided with four retractable wheels, such as 146 and 148, carried by arms, such as 150 and 152, integral with a pivot, such as 154, directed in the longitudinal direction, of the carriage, that is to say - say parallel to his direction of advancement. These wheels 146 and 148 can be brought by appropriate means (not shown) in a position to derail the carriage, that is to say to move it transversely and make it leave the rails on which it moves to allow for example the passage of a train between two adjustment operations. To carry out this shifting operation, it is also necessary to place sections of rails on the one hand between the two rails of the track, perpendicular to the direction of the track and on the other hand on the outside of the track towards which it is desired to move. carriage.

On a représenté sur les figures 7 à 10 une installation fixe équipée d'un dispositif de réglage selon l'invention. Cette installation fixe comprend un bâti 156 fixé au sol et pourvu d'une pluralité de rouleaux 158 destinés à faire glisser deux rails 160 et 162 au moyen d'un dispositif de traction (non représenté) pour les amener dans une position telle que leurs abouts respectifs 164 et 166 se trouvent en position de réglage et de soudage, c'est-à-dire sensiblement au milieu du bâti 156 en ménageant entre eux la distance intercalaire nécessaire pour le coulée ultérieure de la soudure aluminothermique. Le bâti 156 est pourvu d'un dispositif de réglage 168 selon l'invention. Ce dispositif 168 est solidaire de deux bras 170 et 172 montés pivotants autour d'un axe 174 du bâti 156, disposé parallèlement à la direction des rails à régler. Le dispositif 168 peut être déplacé entre une position de service, c'est-à-dire une position horizontale dans laquelle les appuis 176, 178, 180 et 182 du dispositif viennent s'appliquer sur les côtés des champignons des rails (cf. figures 7, 8 et 10) et une position verticale d'escamotage 168' (cf. figures 9 et 10). Pour faciliter le déplacement du dispositif de l'une à l'autre de ces deux positions, un ressort de compensation 184 est prévu autour de l'axe 174 (cf. figure 9).FIGS. 7 to 10 show a fixed installation equipped with an adjustment device according to the invention. This fixed installation comprises a frame 156 fixed to the ground and provided with a plurality of rollers 158 intended to slide two rails 160 and 162 by means of a traction device (not shown) to bring them into a position such that their ends respectively 164 and 166 are in the adjustment and welding position, that is to say substantially in the middle of the frame 156, leaving between them the intermediate distance necessary for the subsequent casting of the aluminothermic weld. The frame 156 is provided with an adjustment device 168 according to the invention. This device 168 is integral with two arms 170 and 172 pivotally mounted around an axis 174 of the frame 156, arranged parallel to the direction of the rails to be adjusted. The device 168 can be moved between a service position, that is to say a horizontal position in which the supports 176, 178, 180 and 182 of the device come to apply on the sides of the mushrooms of the rails (cf. figures 7, 8 and 10) and a vertical retracting position 168 ′ (cf. FIGS. 9 and 10). To facilitate the movement of the device from one to the other of these two positions, a compensation spring 184 is provided around the axis 174 (cf. FIG. 9).

Le bâti 156 est par ailleurs pourvu d'un creuset aluminothermique 186 porté par l'intermédiaire d'une colonne 188 pivotante et réglable en hauteur dont le pied est solidaire du bâti 156. Ce creuset 186 peut être déplacé entre une position de service 186 dans laquelle il se trouve juste au-dessus de l'intercalaire entre les deux abouts 164 et 166 et une position 186' où il se trouve escamoté (cf. figure 8).The frame 156 is moreover provided with an aluminothermic crucible 186 carried by means of a pivoting and height-adjustable column 188 whose base is secured to the frame 156. This crucible 186 can be moved between a service position 186 in which it is located just above the insert between the two ends 164 and 166 and a position 186 'where it is retracted (see Figure 8).

Sur le bâti 156 est par ailleurs prévu un support 190 équipé d'un outil d'ébarvurage 192 destiné à éliminer l'excédent de soudure formé autour des abouts après réalisation de la soudure aluminothermique au moyen du creuset 186. L'outil d'ébravurage 192 est porté, suspendu à l'horizontale, par un bras 194 pivotant autour d'un axe horizontal 196 sous l'action d'un vérin 198 (cf. figure 7). Cet outil peut être déplacé entre une position haute d'escamotage (cf. figure 7) et une position basse de service en suivant une trajectoire circulaire T.On the frame 156 is also provided a support 190 equipped with a deburring tool 192 intended to remove the excess weld formed around the ends after completion of the thermite welding by means of the crucible 186. The deburring tool 192 is carried, suspended horizontally, by an arm 194 pivoting about a horizontal axis 196 under the action of a jack 198 (cf. FIG. 7). This tool can be moved between a high retraction position (see Figure 7) and a low service position by following a circular path T.

L'outil 192 comporte deux couteaux pivotants 200 et 202 susceptibles d'être déplacés dans le sens longitudinal des rails sous l'action de deux vérins parallèles 204 et 206 prenant appui par une base 208 sur le support 190 lorsque l'outil 192 est en position de service.The tool 192 comprises two pivoting knives 200 and 202 capable of being displaced in the longitudinal direction of the rails under the action of two parallel cylinders 204 and 206 bearing by a base 208 on the support 190 when the tool 192 is in service position.

Le déplacement des couteaux provoque l'élimination de l'excédent de soudure formé à la jonction des deux abouts. Pendant lés opérations de soudage et d'ébavurage, le rail 162 est maintenu par un ensemble de blocage 210 solidaire du bâti 156. Cet ensemble comporte deux coins mobiles 212 et 214 déplaçables selon des directions angulaires symétriques de part et d'autre de l'axe longitudinal des rails.The displacement of the knives causes the elimination of the excess weld formed at the junction of the two ends. During the welding and deburring operations, the rail 162 is held by a locking assembly 210 integral with the frame 156. This assembly comprises two movable corners 212 and 214 displaceable in symmetrical angular directions on either side of the longitudinal axis of the rails.

Les deux coins 212 et 214 sont actionnés respectivement sous l'action de têtes rotatives d'entraînement 216 et 218 à l'encontre de deux ressorts 220 et 222.The two corners 212 and 214 are actuated respectively under the action of rotary drive heads 216 and 218 against two springs 220 and 222.

L'installation des figures 7 à 10 s'utilise de la manière suivante. On amène les deux rails à souder en les faissant glisser sur les rouleaux de manière que les abouts à souder se trouvent dans la zone centrale du bâti en ménageant une distance intercalaire convenable entre lesa bouts. On amène le dispositif de réglage en position de service et on effectue le réglage comme indiqué précédemment. On actionne l'ensemble de blocage pour bloquer le rail correspondant. On amène le creuset aluminothermique en position de soudure et on effectue la soudure.The installation of Figures 7 to 10 is used as follows. The two rails to be welded are brought by sliding them over the rollers so that the butt ends to be welded are located in the central zone of the frame, leaving a suitable intermediate distance between the ends. The adjustment device is brought into the operating position and the adjustment is carried out as indicated above. We actuate the blocking assembly to block the rail corresponding. The aluminothermic crucible is brought into the welding position and the welding is carried out.

On écarte ensuite le creuset en on ramène le dispositif de réglage en position d'escamotage.Then the crucible is moved aside and the adjustment device is brought back to the retracted position.

On réalise l'ébavurage de la soudure et on débloque l'ensemble de blocage. On peut alors déplacer le rail sur les rouleaux pour l'évacuer ou pour y adjoindre un nouveau troçon par soudage.The weld is deburred and the blocking assembly is released. We can then move the rail on the rollers to evacuate it or to add a new section by welding.

Le dispositif de l'invention peut être ainsi utilisé à la soudure de rails, en particulier de rails de chemin de fer, en voie ou en installation fixe.The device of the invention can thus be used for welding rails, in particular railway rails, on track or in a fixed installation.
