Description

DISPOSITIF DE SUPPORT D'UN RAIL DE REMPLACEMENT ET PROCÉDÉ D'UTILISATION DE CE DISPOSITIF DEVICE FOR SUPPORTING A REPLACEMENT RAIL AND METHOD FOR USING THIS DEVICE
Domaine technique Technical area
[0001] La présente invention concerne un dispositif de support d’un rail de remplacement, le dispositif étant destiné à être rendu solidaire d’un rail circulé. La présente invention concerne également un procédé de montage du dispositif. The present invention relates to a device for supporting a replacement rail, the device being intended to be made integral with a circulating rail. The present invention also relates to a method of mounting the device.
Technique antérieure Prior art
[0002] Une voie ferrée s’étendant selon une direction longitudinale comprend deux rails longitudinaux espacés selon une direction transverse perpendiculaire à la direction longitudinale et à une direction verticale correspondant à direction du champ de gravité terrestre. Les rails longitudinaux sont dits des rails circulés car un train peut circuler dessus. [0002] A railway track extending in a longitudinal direction comprises two longitudinal rails spaced in a transverse direction perpendicular to the longitudinal direction and in a vertical direction corresponding to the direction of the earth's gravity field. Longitudinal rails are called running rails because a train can travel on them.
[0003] En préalable à une opération de remplacement des rails circulés, il est connu de disposer des coupons de rails, c’est-à-dire des tronçons de rails, le long de la voie et généralement à l’extérieur de celle-ci. Il est souhaitable que les tronçons de rail de remplacement soient disposés et maintenus au sol à un endroit donné pour éviter tout mouvement de ceux-ci au passage d’un train, en particulier à grande vitesse. Ces tronçons de rail de remplacement sont dans une position d’attente. [0003] Prior to an operation to replace the running rails, it is known to place rail coupons, that is to say sections of rails, along the track and generally outside it. this. It is desirable that the sections of replacement rail be arranged and maintained on the ground in a given location to prevent any movement of them when a train passes, particularly at high speed. These replacement rail sections are in a waiting position.
[0004] A cette fin, de nombreuses solutions techniques ont été développées. Parmi celles- ci, on connaît un dispositif de support en L comprenant une partie de fixation sur un patin du rail et une seconde partie fixée rigidement à la première partie. La première partie et la seconde partie ont une forme allongée selon une direction transverse au rail. La seconde partie comprend une partie de réception d’un rail. Si ce type de dispositif s’avère simple à concevoir, il n’est toutefois pas optimal car la rigidité de l’ensemble peut conduire à une torsion importante sur le rail circulé. Par ailleurs, la typologie de certaines traverses et de plusieurs systèmes d’attaches sont incompatibles avec l’installation du dispositif. [0004] To this end, numerous technical solutions have been developed. Among these, we know an L-shaped support device comprising a fixing part on a shoe of the rail and a second part rigidly fixed to the first part. The first part and the second part have an elongated shape in a direction transverse to the rail. The second part includes a part for receiving a rail. Although this type of device is simple to design, it is not optimal because the rigidity of the assembly can lead to significant twisting on the rail being run. Furthermore, the typology of certain crosspieces and several fastening systems are incompatible with the installation of the device.
[0005] Dans un dispositif connu, le dispositif de support d’un rail de remplacement comprend une première partie fixée sur une traverse et une seconde partie aimantée apte à venir se fixer sur l’âme d’un rail circulé. Cependant, l’aimantation doit être suffisamment importante pour garantir une fixation pérenne ce qui rend le dispositif potentiellement très coûteux et s’avère au demeurant pas garantie. Par ailleurs, ce type de système s’avère fragile. [0005] In a known device, the device for supporting a replacement rail comprises a first part fixed on a crosspiece and a second magnetic part capable of being fixed on the core of a running rail. However, the magnetization must be sufficiently significant to guarantee lasting fixation, which makes the device potentially very expensive and is not guaranteed. Furthermore, this type of system turns out to be fragile.
Résumé [0006] Il est ainsi proposé un dispositif de support d'un rail de remplacement destiné à être rendu solidaire d'un rail circulé, comprenant : une première partie s'étendant selon une première direction et comportant des moyens de fixation amovibles à un patin d'un rail circulé, une seconde partie de réception d’un rail d’attente, cette seconde partie étant mobile en rotation autour d’un axe relativement à la première partie et comportant deux portions latérales s’étendant selon une première direction longitudinale parallèle à l’axe de rotation, lesdites deux portions latérales étant destinées à chacune venir en appui sur une traverse, la seconde partie comprenant des moyens de blocage d’un rail d’attente selon au moins une deuxième direction perpendiculaire à la première direction longitudinale. Summary [0006] A device is thus proposed for supporting a replacement rail intended to be made integral with a circulating rail, comprising: a first part extending in a first direction and comprising removable fixing means to a shoe of a circulating rail, a second part for receiving a waiting rail, this second part being movable in rotation around an axis relative to the first part and comprising two lateral portions extending in a first parallel longitudinal direction to the axis of rotation, said two lateral portions each being intended to bear on a crosspiece, the second part comprising means for blocking a waiting rail in at least a second direction perpendicular to the first longitudinal direction.
[0007] Selon la présente invention, le dispositif de support est formé en deux parties dont l’une est mobile par rapport à l’autre. La première partie peut ainsi être simplement et rapidement fixée à un rail circulé et la seconde partie mobile par rapport à la première partie est disposée sur deux traverses consécutives selon la direction longitudinale. La liaison en rotation entre les deux parties permet de disposer la seconde partie de manière simple et rapide sur deux traverses consécutives et cela indépendamment de la hauteur des traverses. Par ailleurs, cette articulation en rotation couplée à la disposition de la seconde partie sur deux traverses consécutives rend le maintien de cette seconde partie, destinée à supporter un rail de remplacement, indépendante de la hauteur du ballast, ce qui la manipulation du dispositif simple et rapide pour un opérateur. Le rail est ici un rail de remplacement c’est-à-dire un rail destiné à remplacer le rail circulé duquel le dispositif est rendu solidaire. La première direction et la deuxième direction sont fixes relativement à la seconde partie B et sont donc déplaçables relativement à la première partie autour de l’axe X. [0007] According to the present invention, the support device is formed in two parts, one of which is movable relative to the other. The first part can thus be simply and quickly fixed to a running rail and the second part movable relative to the first part is arranged on two consecutive sleepers in the longitudinal direction. The rotating connection between the two parts makes it possible to arrange the second part simply and quickly on two consecutive sleepers, regardless of the height of the sleepers. Furthermore, this rotating articulation coupled with the arrangement of the second part on two consecutive sleepers makes the maintenance of this second part, intended to support a replacement rail, independent of the height of the ballast, which makes the handling of the device simple and fast for an operator. The rail here is a replacement rail, that is to say a rail intended to replace the circulating rail to which the device is attached. The first direction and the second direction are fixed relative to the second part B and are therefore movable relative to the first part around the axis X.
[0008] La première partie peut comprendre une embase sensiblement plane s’étendant selon une quatrième direction perpendiculaire à l’axe de rotation et dont une première extrémité selon la quatrième direction est reliée en rotation à la seconde partie autour dudit axe et une seconde extrémité opposée comprend des moyens de serrage de la première partie sur un patin d’un rail circulé. Les moyens de serrage peuvent être amovibles sur la première partie de manière à notamment faciliter l’insertion de ladite portion transverse de la première partie sous un patin d’un rail circulé. Ainsi, les moyens de serrage sont disposés sur la seconde extrémité lorsqu’elle celle-ci est passée sous le patin du rail circulé sur lequel on souhaite fixer le dispositif. Le terme « plane » en relation avec l’embase vise à définir une forme générale de l’embase. L’embase peut ainsi avoir une forme sensiblement plane et comprendre une ouverture permettant notamment de l’alléger. [0008] The first part may comprise a substantially planar base extending in a fourth direction perpendicular to the axis of rotation and of which a first end in the fourth direction is connected in rotation to the second part around said axis and a second end opposite comprises means for clamping the first part on a shoe of a circulating rail. The clamping means can be removable on the first part so as to facilitate the insertion of said transverse portion of the first part under a shoe of a traveling rail. Thus, the clamping means are arranged on the second end when it has passed under the shoe of the running rail on which it is desired to fix the device. The term “plane” in relation to the base aims to define a general shape of the base. The base can thus have a substantially planar shape and include an opening making it possible in particular to lighten it.
[0009] La première extrémité de l’embase peut comprendre au moins une encoche, de préférence deux encoches, de réception et de retenue, selon une cinquième direction perpendiculaire à la première direction et à la quatrième direction, d’un premier bord d’un patin d’un rail circulé, lesdites deux encoches étant espacées selon l’axe de rotation. [0009] The first end of the base may comprise at least one notch, preferably two notches, for receiving and retaining, in a fifth direction perpendicular to the first direction and to the fourth direction, of a first edge of a shoe of a circulating rail, said two notches being spaced along the axis of rotation.
[0010] Chaque portion latérale de la seconde partie comprend une surface supérieure plane, lesdites deux surfaces supérieures étant comprises dans un même premier plan. De cette manière, les surfaces supérieures planes des portions latérales de la seconde partie peuvent recevoir le patin d’un rail de remplacement à une même position selon la troisième direction, ce qui permet un bon support du rail de remplacement. Les termes supérieure et inférieure doivent être comprises relativement à une direction verticale lorsque le dispositif est installé entre deux traverses. On comprendra que les surfaces visées ne sont alors pas nécessairement strictement perpendiculaires à la direction verticale. [0010] Each side portion of the second part comprises a flat upper surface, said two upper surfaces being included in the same first plane. In this way, the flat upper surfaces of the lateral portions of the second part can receive the shoe of a replacement rail in the same position in the third direction, which allows good support of the replacement rail. The terms upper and lower must be understood relative to a vertical direction when the device is installed between two sleepers. It will be understood that the targeted surfaces are then not necessarily strictly perpendicular to the vertical direction.
[0011] La seconde partie peut comprendre deux cloisons dont des extrémités supérieures sont alignées suivant un même second plan. Ces cloisons peuvent être agencées entre les deux portions latérales de la seconde partie. Les cloisons permettent de rigidifier la seconde partie et peuvent servir d’appui au rail de remplacement lorsque ledit premier plan est confondu avec le premier plan. The second part may comprise two partitions whose upper ends are aligned along the same second plane. These partitions can be arranged between the two side portions of the second part. The partitions make it possible to stiffen the second part and can serve as support for the replacement rail when said first plane coincides with the first plane.
[0012] La seconde partie peut comprendre un organe réhausseur comportant une surface d’appui d’un rail de remplacement, l’organe réhausseur étant apte à prendre une première position dans laquelle la surface d’appui est agencée en dessous dudit plan et une seconde position dans laquelle la surface d’appui est agencée en dessus dudit plan. L’organe réhausseur permet ainsi de soulever un rail de remplacement des portions latérales de la seconde partie de manière à permettre la libre dilatation de celui-ci lors de son chauffage au vue du soudage. [0012] The second part may comprise a raising member comprising a bearing surface of a replacement rail, the raising member being able to take a first position in which the bearing surface is arranged below said plane and a second position in which the support surface is arranged above said plane. The raising member thus makes it possible to lift a replacement rail of the lateral portions of the second part so as to allow the free expansion of the latter during its heating for welding.
[0013] L’ organe réhausseur peut par exemple comprendre un axe excentrique dont la surface externe forme la surface d’appui. La surface externe peut être formée dans un cylindre libre en rotation. [0013] The raising member can for example comprise an eccentric axis whose external surface forms the support surface. The outer surface may be formed into a free rotating cylinder.
[0014] La seconde partie peut comprendre au moins une butée apte à venir en butée sur un bord supérieur du patin d’un rail circulé la première partie est fixée sur ledit rail circulé. [0014] The second part may comprise at least one stop capable of abutting on an upper edge of the shoe of a running rail; the first part is fixed on said running rail.
[0015] La seconde partie peut comprendre au moins deux butées espacées l’une de l’autre selon l’axe de rotation. [0016] Lorsqu’il y a deux butées, elles peuvent être espacées l’une de l’autre selon l’axe de rotation. Ces butées évitent que le rail de remplacement disposé sur la seconde partie puisse être déplacé sur le rail circulé. On limite ainsi les manipulations mal intentionnées. The second part may comprise at least two stops spaced from one another along the axis of rotation. [0016] When there are two stops, they can be spaced from one another along the axis of rotation. These stops prevent the replacement rail placed on the second part from being moved on the rail being circulated. This limits malicious manipulation.
[0017] Les moyens de blocage selon la deuxième direction peuvent comprendre deux rebords longitudinaux formés sur chaque portion latérale, ces rebords longitudinaux délimitant ensemble une gorge longitudinale de réception d’un rail de remplacement. The blocking means in the second direction may comprise two longitudinal edges formed on each lateral portion, these longitudinal edges together delimiting a longitudinal groove for receiving a replacement rail.
[0018] Les moyens de blocage peuvent être aptes à bloquer le rail selon une troisième direction perpendiculaire à la deuxième direction et à la première direction. La troisième direction est fixe relativement à la seconde partie B et est donc déplaçable relativement à la première partie autour de l’axe X. La première direction, la seconde direction et la troisième direction sont perpendiculaires deux à deux. The blocking means may be able to block the rail in a third direction perpendicular to the second direction and the first direction. The third direction is fixed relative to the second part B and is therefore movable relative to the first part around the axis X. The first direction, the second direction and the third direction are perpendicular in pairs.
[0019] Les moyens de blocage peuvent comprendre au moins un organe mobile entre une première position de libération du rail de remplacement selon la troisième direction et une seconde position de blocage du rail de remplacement selon la troisième direction. The blocking means may comprise at least one movable member between a first position for releasing the replacement rail in the third direction and a second blocking position for the replacement rail in the third direction.
[0020] Ainsi, on comprend qu’un rail de remplacement positionné sur les deux portions latérales est bloqué sur la direction transverse et est également bloqué, en utilisation, selon la direction verticale. Ainsi, le rail est solidaire de la seconde partie, moyennant les espaces prévus entre le rail de remplacement les rebords de la gorge et l’espace entre l’organe mobile et le champignon du rail de remplacement. [0020] Thus, we understand that a replacement rail positioned on the two lateral portions is blocked in the transverse direction and is also blocked, in use, in the vertical direction. Thus, the rail is integral with the second part, through the spaces provided between the replacement rail, the edges of the groove and the space between the movable member and the head of the replacement rail.
[0021] Le dispositif peut comprendre des moyens d’isolation électrique de la première partie et de la seconde de la seconde partie. The device may include means for electrically isolating the first part and the second part of the second part.
[0022] Les moyens d’isolation électrique peuvent comprendre une douille portée par une tige de liaison en rotation de la première partie à la seconde partie, la douille étant intercalée entre la première partie et la seconde partie. The electrical insulation means may comprise a socket carried by a connecting rod in rotation from the first part to the second part, the socket being interposed between the first part and the second part.
[0023] A la différence de la technique antérieure, l’isolation électrique est intégrée à la tige de liaison et n’est pas susceptible d’être endommagée. En effet, dans l’art antérieur, l’isolant électrique était intégré au rail circulé et pouvait être endommagé lors de la circulation des trains et même dans certains cas oublié d’être installé. Unlike the prior art, the electrical insulation is integrated into the connecting rod and is not likely to be damaged. Indeed, in the prior art, the electrical insulator was integrated into the running rail and could be damaged during the movement of trains and in certain cases even forgotten to be installed.
[0024] Le présent document concerne également un ensemble comprenant un dispositif tel que décrit précédemment, dans lequel un rail circulé est fixé à la première partie est fixé à un rail circulé. The present document also relates to an assembly comprising a device as described above, in which a running rail is fixed to the first part and is fixed to a running rail.
[0025] La première partie peut être intercalée entre deux traverses successives et dans lequel la quatrième direction peut être perpendiculaire au rail circulé. [0026] Une portion latérale peut être portée par une traverse et une autre portion latérale peut être portée par une traverse adjacente. The first part can be inserted between two successive sleepers and in which the fourth direction can be perpendicular to the rail being traveled. [0026] A side portion can be carried by a crosspiece and another side portion can be carried by an adjacent crosspiece.
[0027] Il comprend encore un procédé d’utilisation du dispositif décrit ci-dessus comprenant les étapes suivantes : a) Fixation de la première partie sur un patin d’un rail circulé de manière à ce que la première partie (A) soit agencée entre deux traverses successives, b) Rotation de la seconde partie jusqu’à ce que les deux portions latérales viennent en contact avec lesdites deux traverses successives. [0027] It also includes a method of using the device described above comprising the following steps: a) Fixing the first part on a shoe of a circulating rail so that the first part (A) is arranged between two successive sleepers, b) Rotation of the second part until the two lateral portions come into contact with said two successive sleepers.
[0028] Dans une étape ultérieure, un rail d’attente ou de remplacement est disposée sur les portions latérales. [0028] In a subsequent step, a waiting or replacement rail is placed on the side portions.
[0029] Des cales peuvent être disposées sur lesdites deux traverses, les deux portions latérales étant appliquées sur les cales. Shims can be placed on said two crosspieces, the two side portions being applied to the wedges.
[0030] Dans une étape préalable à l’étape a), la première partie est insérée sous le patin du rail circulé. [0030] In a step prior to step a), the first part is inserted under the shoe of the running rail.

Description des modes de réalisation Description of embodiments
[0042] Il est maintenant fait référence aux figures 1 à 3 qui représentent un dispositif de support d’un rail de remplacement selon l’invention. [0042] Reference is now made to Figures 1 to 3 which represent a device for supporting a replacement rail according to the invention.
[0043] Le dispositif de support 10 comprend une première partie A et une seconde partie B, la première partie A et la seconde partie B étant reliées en rotation l’une relativement à l’autre autour d’un axe X s’étendant selon une direction longitudinale L1 ’. La figure 2 illustre un dispositif 10 dont la seconde partie B repose sur deux traverses T adjacentes. La première partie A comprend des moyens de fixation A1 amovibles à un patin d’un rail circulé RC, ces moyens permettant de fixer rigidement et d’enlever la première partie B du patin du rail circulé RC. Le dispositif sera décrit en référence à six directions de l’espace, une première direction L1 ou direction longitudinale, une deuxième direction L2 et une troisième direction L3 perpendiculaires deux à deux, et une quatrième direction L4, une cinquième direction L5 et une sixième direction perpendiculaires deux à deux. On comprend ainsi qu’un second repère orthonormé est fixe relativement à la première partie A et est défini par la quatrième direction L4, la cinquième direction L5 et une sixième direction correspondant à la direction L1 ’ et qu’un premier repère orthonormé est fixe relativement à la seconde partie B et est défini par la première direction L1 , la deuxième direction L2 et la troisième direction L3. En utilisation, la cinquième direction L5 correspond sensiblement à la direction verticale tandis que la troisième direction L3 coplanaire avec la cinquième direction L5 peut former un angle avec celle-ci, cet angle étant fonction de la position de la première partie A relativement à la seconde partie B autour de l’axe X et donc fonction de la hauteur des traverses comme cela apparaitra clairement dans ce qui suit. La première direction L1 et la sixième direction L1 ’ sont toujours parallèles l’une à l’autre et à l’axe X de rotation de la seconde partie B par rapport à la première partie A. [0044] Lorsque la deuxième direction L2 et la quatrième direction L4 sont parallèles alors la troisième direction L3 et la cinquième direction L5 sont également parallèles. The support device 10 comprises a first part A and a second part B, the first part A and the second part B being connected in rotation relative to each other around an axis a longitudinal direction L1 '. Figure 2 illustrates a device 10 whose second part B rests on two adjacent crosspieces T. The first part A comprises removable fixing means A1 to a shoe of an RC circulating rail, these means making it possible to rigidly fix and remove the first part B from the shoe of the RC circulating rail. The device will be described with reference to six directions of space, a first direction L1 or longitudinal direction, a second direction L2 and a third direction L3 perpendicular in pairs, and a fourth direction L4, a fifth direction L5 and a sixth direction perpendicular in pairs. It is thus understood that a second orthonormal reference frame is fixed relative to the first part A and is defined by the fourth direction L4, the fifth direction L5 and a sixth direction corresponding to the direction L1 'and that a first orthonormal reference frame is fixed relatively to the second part B and is defined by the first direction L1, the second direction L2 and the third direction L3. In use, the fifth direction L5 corresponds substantially to the vertical direction while the third direction L3 coplanar with the fifth direction L5 can form an angle therewith, this angle being a function of the position of the first part A relative to the second part B around the axis The first direction L1 and the sixth direction L1' are always parallel to each other and to the axis X of rotation of the second part B relative to the first part A. When the second direction L2 and the fourth direction L4 are parallel then the third direction L3 and the fifth direction L5 are also parallel.
[0045] Comme cela est visible sur les figures 1 à 3, la première partie A comprend une embase A2 sensiblement plane s’étendant selon la quatrième direction L4. Cette embase A2 comprend une découpe A3 à contour fermé et porte une tige A4 à une première extrémité selon la quatrième direction L4 et des moyens de serrage A5 à une seconde extrémité. Les moyens de serrage appartiennent aux moyens de fixation amovibles et sont aptes à réaliser un serrage de la première partie A sur un patin P d’un rail circulé RC comme cela apparaitra ultérieurement. La tige A4 est insérée dans des orifices de deux branches A6 portées par l’embase A2, la tige A4 étant solidaire desdites deux branches A6. On observe que la tige A4 est engagée en rotation dans des orifices de deux branches B3 de la seconde partie B. Ainsi, la première partie A et la seconde partie B sont articulées en rotation l’une par rapport à l’autre autour de l’axe X de la tige A4. As can be seen in Figures 1 to 3, the first part A comprises a substantially flat base A2 extending in the fourth direction L4. This base A2 comprises a cutout A3 with a closed contour and carries a rod A4 at a first end in the fourth direction L4 and clamping means A5 at a second end. The tightening means belong to the removable fixing means and are capable of tightening the first part A on a shoe P of a circulating rail RC as will appear later. The rod A4 is inserted into the orifices of two branches A6 carried by the base A2, the rod A4 being integral with said two branches A6. We observe that the rod A4 is engaged in rotation in orifices of two branches B3 of the second part B. Thus, the first part A and the second part B are articulated in rotation relative to each other around the X axis of rod A4.
[0046] Comme cela est illustré en figure 8, le dispositif 10 comprend des moyens d’isolation électrique de la première partie A et de la seconde partie B. De cette manière, le courant qui circule dans le rail circulé RC ne peut pas passer dans la seconde partie B. Dans le cas contraire, le courant pourrait passer de la première partie A à la seconde partie B, puis dans un rail de remplacement RA porté par la seconde partie B puis de nouveau dans une seconde partie B d’un autre dispositif 10 agencé plus loin le long de la voie ferrée, le courant passant ensuite dans la première partie A de cet autre dispositif 10 puis vers le rail circulé RC. Une telle circulation de courant évite de parasiter la circulation de courant qui s’effectue dans les rails circulés RC. Les moyens d’isolation électrique comprennent une douille A7 comportant une partie cylindrique A7-1 et une partie annulaire radiale A7-2 (figure 8). Chaque partie cylindrique A7-1 entoure la tige A4 et est montée dans un orifice d’une branche A6 de la première partie A. Par ailleurs, la partie annulaire radiale A7-2 est intercalée selon la sixième direction longitudinale L1 ’ entre une branche A6 de la première partie A et une branche B3 de la seconde partie B. Ainsi agencés, les moyens d’isolation électrique A7 permettent d’isoler électriquement la première partie A de la seconde partie B. Les douilles A7 sont ici rendues solidaires de la tige A4. As illustrated in Figure 8, the device 10 comprises means of electrical insulation of the first part A and the second part B. In this way, the current which circulates in the circulating rail RC cannot pass in the second part B. Otherwise, the current could pass from the first part A to the second part B, then in a replacement rail RA carried by the second part B then again in a second part B of a another device 10 arranged further along the railway track, the current then passing through the first part A of this other device 10 then towards the circulating rail RC. Such current circulation avoids interfering with the current circulation which takes place in the RC circulating rails. The electrical insulation means include a socket A7 comprising a cylindrical part A7-1 and a radial annular part A7-2 (figure 8). Each cylindrical part A7-1 surrounds the rod A4 and is mounted in an orifice of a branch A6 of the first part A. Furthermore, the radial annular part A7-2 is interposed in the sixth longitudinal direction L1 'between a branch A6 of the first part A and a branch B3 of the second part B. Thus arranged, the electrical insulation means A7 make it possible to electrically isolate the first part A from the second part B. The sockets A7 are here made integral with the rod A4.
[0047] Les branches A6 de la première partie A comprennent chacune un doigt A6-1 , s’étendant selon la quatrième direction L4, vers les moyens de serrage A5 de la seconde extrémité de la première partie A. Ces doigts A6-1 ou ergots délimitent chacun avec l’embase A2 une encoche E destinée à recevoir un premier bord d’un patin P d’un rail circulé RC. Les deux encoches E sont ainsi espacées l’une de l’autre selon la sixième direction longitudinale L1 ’. Les doigts A6-1 appartiennent aux moyens de fixation amovibles puisqu’ils coopèrent avec les moyens de serrage A5. [0048] Les moyens de serrage A5 de la première partie comprennent un organe mobile A8 selon la cinquième direction L5 et recevant une tige filetée A9 traversant ledit organe mobile A8 et vissée dans l’embase A2. L’organe mobile A8 comprend un téton A8-1 orienté vers les ergots A6-1 selon la quatrième direction L4 et délimitant avec l’embase une encoche de réception d’un second bord d’un patin d’un rail circulé RC. La tige filetée A9 peut être rendue solidaire de l’organe mobile afin d’éviter de perdre ou égarer la tige filetée. Le terme « solidaire » indique ici que les deux pièces précitées sont manipulables simultanément, le mouvement relatif de l’une des pièces par rapport à l’autre étant toujours permis pour permettre la fixation de la partie fixe A sur le rail circulé RC. The branches A6 of the first part A each comprise a finger A6-1, extending in the fourth direction L4, towards the clamping means A5 of the second end of the first part A. These fingers A6-1 or lugs each delimit with the base A2 a notch E intended to receive a first edge of a shoe P of a circulating rail RC. The two notches E are thus spaced from one another in the sixth longitudinal direction L1 '. The fingers A6-1 belong to the removable fixing means since they cooperate with the clamping means A5. The clamping means A5 of the first part comprise a movable member A8 in the fifth direction L5 and receiving a threaded rod A9 passing through said movable member A8 and screwed into the base A2. The movable member A8 comprises a pin A8-1 oriented towards the lugs A6-1 in the fourth direction L4 and delimiting with the base a notch for receiving a second edge of a shoe of a circulating rail RC. The threaded rod A9 can be made integral with the movable member in order to avoid losing or misplacing the threaded rod. The term "integral" indicates here that the two aforementioned parts can be manipulated simultaneously, the relative movement of one of the parts relative to the other always being permitted to allow the fixing of the fixed part A on the circulating rail RC.
[0049] Le positionnement de la première partie A sur un rail circulé est réalisée de la manière suivante. L’organe mobile A8 de serrage est retiré, l’embase A2 est insérée sous un rail circulé RC et de manière à ce qu’un premier bord d’un patin dudit rail circulé RC vienne dans les encoches délimitées par les ergots A6-1. Dans un second temps, l’organe mobile A8 est montée sur l’embase A2 et est serré de manière à bloquer le second bord opposé du patin du rail circulé RC. Ainsi positionné, la première partie A est bloquée sur le patin du rail circulé RC et la seconde partie B peut être déplacé en rotation autour de l’axe X de la tige (figure 3). Dans cette position l’axe X de la tige est parallèle à l’axe longitudinale du rail circulé RC. The positioning of the first part A on a circulating rail is carried out in the following manner. The movable clamping member A8 is removed, the base A2 is inserted under an RC circulating rail and so that a first edge of a shoe of said RC circulating rail comes into the notches delimited by the lugs A6-1 . Secondly, the movable member A8 is mounted on the base A2 and is tightened so as to block the second opposite edge of the shoe of the circulating rail RC. Thus positioned, the first part A is blocked on the shoe of the circulating rail RC and the second part B can be moved in rotation around the axis X of the rod (figure 3). In this position the X axis of the rod is parallel to the longitudinal axis of the RC circulating rail.
[0050] On décrit maintenant la seconde partie B du dispositif 10 de support d’un rail de remplacement RA. Cette seconde partie B est proprement dite destinée à supporter un rail de remplacement RA. Elle comprend une structure rigide formée d’une première paroi longitudinale B1 et d’une seconde paroi longitudinale B2 espacées l’une de l’autre selon la deuxième direction L2. Les parois longitudinales B1 , B2 sont reliées par deux portions latérales B3, B4 et par deux cloisons B5, B6 s’étendant suivant le plan formé par les directions L2 et L3. We now describe the second part B of the device 10 for supporting a replacement rail RA. This second part B is itself intended to support a replacement rail RA. It comprises a rigid structure formed of a first longitudinal wall B1 and a second longitudinal wall B2 spaced from one another in the second direction L2. The longitudinal walls B1, B2 are connected by two lateral portions B3, B4 and by two partitions B5, B6 extending along the plane formed by the directions L2 and L3.
[0051] Les deux portions latérales B3, B4 servent de support à un rail de remplacement RA et comprennent chacune une surface supérieure plane B3-1 , B4-1 qui sont comprises dans un même premier plan de manière à supporter le rail de remplacement RA sur ce plan. De même, les deux cloisons B5, B6 présentent des extrémités supérieures selon la troisième direction L3 qui sont alignées suivant un même second plan, ce second plan étant confondu ici avec le premier plan de manière à aussi pouvoir supporter le rail de remplacement RA. Des cales C peuvent être intercalées entre les branches B3 et B4 et une traverse pour compenser, lorsque cela est nécessaire, une différence de hauteur importante entre un plan horizontal passant par l’axe X de la tige A4 et la surface supérieure des traverses T. De cette manière, on peut garantir un positionnement sensiblement horizontal de la partie B et donc des surfaces B3-1 et B4-1 . Les cales C peuvent être fixées par des vis de fixation traversant les branches B3, B4. The two lateral portions B3, B4 serve as supports for a replacement rail RA and each comprise a flat upper surface B3-1, B4-1 which are included in the same first plane so as to support the replacement rail RA on this level. Likewise, the two partitions B5, B6 have upper ends in the third direction L3 which are aligned along the same second plane, this second plane being merged here with the first plane so as to also be able to support the replacement rail RA. Shims C can be inserted between the branches B3 and B4 and a crosspiece to compensate, when necessary, for a significant difference in height between a horizontal plane passing through the axis X of the rod A4 and the upper surface of the crosspieces T. In this way, we can guarantee a substantially horizontal positioning of part B and therefore surfaces B3-1 and B4-1. The wedges C can be fixed by fixing screws passing through the branches B3, B4.
[0052] On observe que les deux parois longitudinales B1 , B2 s’étendent en saillie selon la troisième direction L3 relativement aux surfaces B3-1 , B4-1 ou au premier plan de manière à former des rebords longitudinaux B1-1 , B2-1. De cette manière, les rebords longitudinaux B1-1 , B2-1 forment ensemble une gorge longitudinale de réception d’un rail de remplacement RA, cette gorge permettant de bloquer le rail de remplacement RA selon la deuxième direction L2. Chaque rebord B1-1 et B2-1 comprend une partie formée sur une portion latérale B3 et une autre partie formée sur l’autre portion latérale B4. [0052] It is observed that the two longitudinal walls B1, B2 extend projecting in the third direction L3 relative to the surfaces B3-1, B4-1 or in the foreground so as to form longitudinal edges B1-1, B2- 1. In this way, the longitudinal edges B1-1, B2-1 together form a longitudinal groove for receiving a replacement rail RA, this groove making it possible to block the replacement rail RA in the second direction L2. Each edge B1-1 and B2-1 comprises a part formed on a side portion B3 and another part formed on the other side portion B4.
[0053] La première paroi longitudinale B1 porte les deux branches B7, ces deux branches B7 s’étendant depuis cette première paroi longitudinale B1 dans un sens opposé à la deuxième paroi longitudinale B2. Chaque branche B7 de la seconde partie B comprend des doigts ou ergots B7-1 de blocage en rotation de la seconde partie B sur le patin P du rail circulé RC sur lequel la première partie A est fixée (figure 1 A, 2B, 6 et 7). Ces ergots B7-1 sont aptes à venir en butée sur un bord du patin P d’un rail circulé RC pour empêcher le basculement de la seconde partie B sur le rail circulé RC. The first longitudinal wall B1 carries the two branches B7, these two branches B7 extending from this first longitudinal wall B1 in a direction opposite to the second longitudinal wall B2. Each branch B7 of the second part B comprises fingers or lugs B7-1 for blocking the rotation of the second part B on the shoe P of the circulating rail RC on which the first part A is fixed (figure 1 A, 2B, 6 and 7). These lugs B7-1 are able to abut on one edge of the shoe P of an RC circulating rail to prevent the tilting of the second part B on the RC circulating rail.
[0054] Le dispositif 10 comprend également des moyens de blocage du rail de remplacement RA sur la seconde partie B et selon la troisième direction L3. Ces moyens de blocage s’avèrent optionnels et permettent de limiter les déplacements selon la troisième direction L3 du rail de remplacement RA lorsqu’un train, plus particulièrement du type à grande vitesse, circule sur les voies ferrées. The device 10 also includes means for blocking the replacement rail RA on the second part B and in the third direction L3. These blocking means are optional and make it possible to limit movements in the third direction L3 of the replacement rail RA when a train, more particularly of the high-speed type, is traveling on the railway tracks.
[0055] Dans la réalisation représentée aux figures, les moyens de blocage selon la troisième direction L3 comprennent au moins un organe mobile B8 entre une première position de libération du rail de remplacement RA selon la troisième direction L3 et une seconde position de blocage du rail de remplacement RA selon la troisième direction L3. Cet organe mobile est mobile en rotation suivant un axe Y perpendiculaire à l’axe X de la tige A4 de la première partie A. Cet axe Y est perpendiculaire aux surfaces B3-1 et B4-1. Dans la seconde position de blocage du rail de remplacement RA, l’extrémité libre de l’organe mobile B8 est positionnée au-dessus du patin P du rail de remplacement RA comme cela est représenté en figure 7. [0055] In the embodiment shown in the figures, the blocking means in the third direction L3 comprise at least one movable member B8 between a first position for releasing the replacement rail RA in the third direction L3 and a second blocking position of the rail replacement RA according to the third direction L3. This movable member is movable in rotation along an axis Y perpendicular to the axis X of the rod A4 of the first part A. This axis Y is perpendicular to the surfaces B3-1 and B4-1. In the second blocking position of the replacement rail RA, the free end of the movable member B8 is positioned above the pad P of the replacement rail RA as shown in Figure 7.
[0056] Le dispositif 10 peut également comprendre un organe réhausseur B9 formé sur la seconde partie B apte à prendre une première position (figure 4A) dans laquelle une surface d’appui B10 est agencée en dessous du premier plan de référence formé par les surfaces B3-1 , B4-1 des portions latérales B3, B4 et une seconde position dans laquelle la surface d’appui B10 est agencée en dessus dudit plan (figure 4B). Cette seconde position est illustrée sur la figure 5 où l’on voit la surface d’appui B10 agencée au-dessus, selon la troisième direction L3. Dans l’exemple illustré aux figures, l’organe réhausseur B9 comprend un axe excentrique B11 dont la surface externe forme la surface d’appui B10. Cette organe réhausseur B9 peut être manipulé entre la première position (figure 4A) et la seconde position (figure 4B) par l’intermédiaire d’un manipulateur permettant de déplacer la surface d’appui B10 de la première position à la seconde position, par exemple une manivelle B12. L’organe réhausseur B9 permet dans sa seconde position ou position haute que le rail de remplacement ne repose plus sur les surfaces supérieure B3-1 , B4-1 des portions latérale B3, B4. L’organe réhausseur est tel que la surface d’appui B10 qui peut être cylindrique est librement rotative autour d’un axe parallèle à la deuxième direction L2. Lorsque le rail d’attente RA est en appui sur la surface d’appui, il réalise de préférence un appui linéique selon la deuxième direction L2 sur la surface d’appui B10. Ainsi, dans la seconde position de l’organe réhausseur B9, l’appui linéique s’étend de préférence selon la deuxième direction L2 afin de faciliter la libre dilation du rail d’attente RA. Dans la première position, l’organe réhausseur agencé entre les portions latérales B3, B4 est ainsi agencé en dessous du premier plan défini par les surfaces B4-1 et B4-2. Il est également alors agencé entre les deux traverses T de support de la seconde partie B. [0056] The device 10 can also comprise a raising member B9 formed on the second part B capable of taking a first position (FIG. 4A) in which a support surface B10 is arranged below the first reference plane formed by the surfaces B3-1, B4-1 of the lateral portions B3, B4 and a second position in which the support surface B10 is arranged above said plane (Figure 4B). This second position is illustrated in Figure 5 where we see the support surface B10 arranged above, in the third direction L3. In the example illustrated in the figures, the raising member B9 comprises an eccentric axis B11 whose external surface forms the support surface B10. This raising member B9 can be manipulated between the first position (Figure 4A) and the second position (Figure 4B) via a manipulator making it possible to move the support surface B10 from the first position to the second position, by example a B12 crank. The raising member B9 allows in its second position or high position that the replacement rail no longer rests on the upper surfaces B3-1, B4-1 of the side portions B3, B4. The raising member is such that the support surface B10 which can be cylindrical is freely rotatable around an axis parallel to the second direction L2. When the waiting rail RA is supported on the support surface, it preferably provides linear support in the second direction L2 on the support surface B10. Thus, in the second position of the raising member B9, the linear support preferably extends in the second direction L2 in order to facilitate the free expansion of the waiting rail RA. In the first position, the raising member arranged between the lateral portions B3, B4 is thus arranged below the first plane defined by the surfaces B4-1 and B4-2. It is also then arranged between the two support crosspieces T of the second part B.
[0057] On notera que les moyens de blocage B8 sont conformés de manière à réaliser un blocage du patin du rail d’attente RA selon la troisième direction avec un jeu J non nul lorsque l’organe réhausseur B9 est dans sa seconde position (figure 10). Ainsi, les moyens de blocage ne restreignent pas la libre dilatation du rail d’attente. Les moyens de blocage B8 assurent un maintien du rail d’attente en position sur la seconde partie B selon la troisième direction L3 sans contrainte de dilatation du rail d’attente selon la première direction L1. [0057] It will be noted that the blocking means B8 are shaped so as to block the pad of the waiting rail RA in the third direction with a non-zero clearance J when the raising member B9 is in its second position (figure 10). Thus, the blocking means do not restrict the free expansion of the waiting rail. The blocking means B8 ensure that the waiting rail is maintained in position on the second part B in the third direction L3 without constraining the expansion of the waiting rail in the first direction L1.
[0058] La figure 9 illustre une variante de réalisation du dispositif selon le présent document, qui est similaire à celui décrit en référence aux figures précédentes et en diffère par les caractéristiques décrites ci-après. L’organe réhausseur est ici actionnée par une manivelle B12 apte à être bloquée par une goupille G engagée dans un rebord latéral B2- 1 afin de bloquée l’organe réhausseur en position haute et ainsi maintenir le rail de remplacement en position de libre dilatation selon sa direction d’extension longitudinale L2. Sur cette figure 10, on observe que le dispositif 10 peut comprendre deux organes B8 de blocage du patin P du rail de remplacement PA selon la troisième direction L3. [0058] Figure 9 illustrates a variant embodiment of the device according to the present document, which is similar to that described with reference to the previous figures and differs by the characteristics described below. The raising member is here actuated by a crank B12 capable of being blocked by a pin G engaged in a lateral rim B2-1 in order to block the raising member in the high position and thus maintain the replacement rail in the position of free expansion according to its direction of longitudinal extension L2. In this Figure 10, we observe that the device 10 can comprise two members B8 for blocking the pad P of the replacement rail PA in the third direction L3.
[0059] La figure 10 illustre une vue selon la première direction longitudinale L1. Le rail de remplacement est positionné sur le dispositif de support 10 lequel est fixé au rail circulé RC. On observe une zone en hachure ZH qui permet correspondant à une zone admissible d’utilisation par des dispositifs ou installation sur la voie ferrée. Toutefois, il s’avère impossible de dépassée cette zone hachurée en hauteur et également en direction latérale, c’est-à-dire vers le rail circulé afin de pas venir en contact avec des parties d’un train circulant. On observe clairement que l’installation du dispositif 10 entre deux traverses permet de réduire l’encombrement du dispositif de support selon la direction vertical puisque celui-ci est agencé entre deux traverses contrairement aux dispositifs de la technique antérieure. [0059] Figure 10 illustrates a view along the first longitudinal direction L1. The replacement rail is positioned on the support device 10 which is attached to the RC circulating rail. We observe a hatched zone ZH which corresponds to an admissible zone of use by devices or installations on the railway track. However, it turns out impossible to go beyond this hatched area in height and also in the lateral direction, that is to say towards the running rail in order to avoid coming into contact with parts of a running train. It is clearly observed that the installation of the device 10 between two crosspieces makes it possible to reduce the bulk of the support device in the vertical direction since it is arranged between two crosspieces unlike the devices of the prior technique.
