Description

Titre de l'invention : Ensemble pour appareil de voie Title of the invention: Switchgear assembly

[001] La présente invention se rapporte au domaine des appareils de voie pour véhicule de type tramway et plus particulièrement au domaine de ces appareils de voie intégrant un mécanisme de gestion de maintenance. The present invention relates to the field of track devices for a tram-type vehicle and more particularly to the field of these track devices incorporating a maintenance management mechanism.

[002] Au même titre que les rails, les appareils de voie sont également soumis à des contraintes régulières générées par les passages des véhicules ou provenant de variations de chaleur ou d’agressions de l’environnement qui conduisent à une usure de certaines des surfaces de l’appareil de voie. Par ailleurs, les appareils de voie étant positionnés stratégiquement le long de voies ferrées pour modifier la direction des véhicules ou au niveau de croisements de voies, certaines portions particulières de ces appareils de voie sont alors soumises à des impacts avec les roues des véhicules qui présentent une récurrence plus importante qu’un simple rail. Soumis à une usure répétée, les appareils de voie et notamment les surfaces de roulement de l’appareil qui tiennent les rôles de contre-aiguilles imposent alors une surveillance et une maintenance régulière de leurs structures susceptibles d’aboutir à leurs réparations voire remplacements. [002] In the same way as the rails, the switches and crossings are also subjected to regular stresses generated by the passage of vehicles or from variations in heat or attacks from the environment which lead to wear of some of the surfaces. switchgear. Furthermore, as the switches are strategically positioned along the tracks to change the direction of vehicles or at track crossings, certain particular portions of these switches are then subjected to impacts with the wheels of the vehicles which present a greater recurrence than a simple rail. Subject to repeated wear, switches and in particular the running surfaces of the device which act as counter-needles then require monitoring and regular maintenance of their structures, which may lead to their repairs or even replacements.

[003] Dans le cadre d’une réparation de la structure d’un appareil de voie formant un contre-aiguille, celle-ci est effectuée sur site et impose un arrêt de l’utilisation de la portion de voie qui comprend l’appareil. Cette réparation consiste pour l’essentiel à des opérations de rechargement avec un métal d’apport adapté de la zone de l’appareil où la fonction de contre-aiguille est opérée, suivies d’une opération de meulage de cette même zone pouvant entraîner le blocage dans le temps de tout déplacement de véhicules sur une portion de voie. Lorsque les réparations à apporter au niveau de cette zone particulière sont trop importantes, une alternative à cette réparation sur site consiste à procéder au remplacement de l’ensemble de la structure qui remplit ce rôle de contre-aiguille. Dans ce cas de figure, des opérations de démontage de la portion d’appareil de voie à remplacer puis d’installation de nouveaux éléments de remplacement conduisent à l’engagement de travaux importants pour la mise en oeuvre de cette solution pour répondre au problème de la dégradation de la structure de l’élément qui forme le contre- aiguille de l’appareil de voie. Par ailleurs, ce type d’intervention est alors susceptible de se compliquer lorsqu’une partie de l’appareil se trouve intégrée au sol par un enrobage ou un béton. As part of a repair of the structure of a track device forming a counter-needle, it is carried out on site and requires stopping the use of the portion of track which includes the device . This repair essentially consists of recharging operations with a suitable filler metal of the area of the device where the counter-needle function is operated, followed by a grinding operation of this same area which may result in the blocking in time of any movement of vehicles on a section of track. When the repairs to be made in this particular area are too extensive, an alternative to this on-site repair consists in replacing the entire structure which fulfills this role of counter-needle. In this case, the dismantling of the portion of the switchgear to be replaced and then the installation of new replacement elements lead to the initiation of major works for the implementation of this solution to respond to the problem of the degradation of the structure of the element which forms the counter-needle of the switchgear. Moreover, this type of intervention is then likely to be complicated when part of the device is integrated into the ground by a coating or concrete.

[004] La présente invention a pour but de pallier ces inconvénients de l’art antérieur en proposant un appareil de voie qui autorise une maintenance facilitée et une intervention rapide pour procéder à la réparation voire au remplacement de surfaces de roulement particulières d’appareil de voie sujettes à l’usure. [004] The present invention aims to overcome these drawbacks of the prior art by proposing a track device which allows easy maintenance and rapid intervention to repair or even replace particular running surfaces of the device. track subject to wear.

[005] L’invention a ainsi pour objet un ensemble pour appareil de voie définissant une voie directe et une voie déviée comprenant : [005] The subject of the invention is thus an assembly for a track device defining a direct track and a deviated track comprising:

- une structure monobloc, - a one-piece structure,

- une aiguille montée mobile sur la structure monobloc, caractérisé en ce que l’ensemble comprend au moins un bloc formant le contre-aiguille, le bloc étant monté amovible sur une partie dédiée de la structure monobloc. - a needle movably mounted on the one-piece structure, characterized in that the assembly comprises at least one block forming the counter-needle, the block being removably mounted on a dedicated part of the one-piece structure.

[006] L’invention a également pour objet un appareil de voie de type aiguillage qui intègre un ensemble selon l’invention. [006] The subject of the invention is also a switch-type track apparatus which integrates an assembly according to the invention.

[0014] [Fig. 7] est une représentation schématique d’une vue supérieure d’un exemple d’appareil de voie intégrant deux ensembles selon l’invention. [0014] [Fig. 7] is a schematic representation of a top view of an example of a turnout incorporating two assemblies according to the invention.

[0015] La présente invention porte sur un ensemble pour appareil de voie 10 définissant une voie directe A et une voie déviée B comprenant : une structure monobloc 2, une aiguille 3 montée mobile sur la structure monobloc 2, caractérisé en ce que l’ensemble comprend au moins un bloc 4 formant le contre-aiguille, le bloc 4 étant monté amovible sur une partie dédiée de la structure monobloc 2. Cette construction particulière dans laquelle le bloc 4 formant le contre-aiguille est amovible par rapport à une structure monobloc 2 qui réalise également une base support sur laquelle une aiguille 3 de l’appareil de voie 10 est mobile, permet d’optimiser la durée d’une intervention sur site en s’affranchissant d’un démontage de l’intégralité de la structure du demi-aiguillage de l’appareil de voie 10 pour se restreindre au seul bloc 4 formant le contre-aiguille à retirer. En étant monté sur la structure monobloc 2, le bloc 4 formant le contre-aiguille présente comme avantage d’être accessible par le dessus pour un intervenant qui souhaite séparer l’élément réalisant le contre-aiguille de son support que forme la structure monobloc 2. Aussi, selon un exemple de réalisation, la structure monobloc 2 présente un arrangement configuré pour accéder par la face supérieure de la structure monobloc 2 au bloc 4 formant le contre-aiguille de façon à séparer le bloc 4 formant le contre-aiguille de son support réalisé par la structure monobloc 2. Cet accès au bloc 4 formant le contre-aiguille depuis le côté supérieur de la structure monobloc 2 autorise un accès direct au contre-aiguille et aux éléments de fixation du bloc 4 formant le contre-aiguille sur la structure monobloc 2. Un tel accès au bloc 4 formant le contre-aiguille et aux éléments de fixation autorise ainsi un détachement et un retrait du bloc 4 formant le contre-aiguille de son support réalisé par la structure monobloc 2 sans qu’il ne soit nécessaire d’accéder aux autres faces latérales et inférieures de la structure monobloc 2, de sorte que le retrait du bloc 4 formant le contre-aiguille peut être effectué sans opération de démontage ou dépose de la structure monobloc 2. De façon complémentaire, l’aiguille 3 également montée mobile sur la structure monobloc 2 est configurée pour buter par une de ses faces latérales contre le bloc 4 formant le contre-aiguille de sorte que l’aiguille 3 n’est pas superposée au-dessus du bloc 4 formant le contre-aiguille et n’interfère pas dans l’accessibilité à ce bloc 4 pour un intervenant. Aussi, l’accessibilité au bloc 4 formant le contre- aiguille ne se trouve pas entravée par l’aiguille 3. The present invention relates to an assembly for track apparatus 10 defining a direct track A and a deviated track B comprising: a one-piece structure 2, a needle 3 movably mounted on the one-piece structure 2, characterized in that the assembly comprises at least one block 4 forming the counter-needle, the block 4 being removably mounted on a dedicated part of the one-piece structure 2. This particular construction in which the block 4 forming the counter-needle is removable relative to a one-piece structure 2 which also produces a support base on which a needle 3 of the track apparatus 10 is movable, makes it possible to optimize the duration of an on-site intervention by eliminating the need to dismantle the entire structure of the half switch of the switch 10 to be restricted to the single block 4 forming the counter-needle to be withdrawn. By being mounted on the one-piece structure 2, the block 4 forming the counter-needle has the advantage of being accessible from above for a worker who wishes to separate the element forming the counter-needle of its support formed by the one-piece structure 2. Also, according to an exemplary embodiment, the one-piece structure 2 has an arrangement configured to access the upper face of the one-piece structure 2 to the block 4 forming the counter-needle so as to separate the block 4 forming the counter-needle from its support produced by the one-piece structure 2. This access to the block 4 forming the counter-needle from the upper side of the one-piece structure 2 allows direct access to the back needle and the fixing elements of the block 4 forming the counter-needle on the one-piece structure 2. Such access to the block 4 forming the counter-needle and to the fixing elements thus allows detachment and removal of the block 4 forming the counter-needle. needle of its support produced by the one-piece structure 2 without it being necessary to access the other side and lower faces of the one-piece structure 2, so that the withdrawal of the block 4 forming the con tre-needle can be performed without dismantling or removing the monobloc structure 2. In a complementary manner, the needle 3 also movably mounted on the monoblock structure 2 is configured to abut by one of its side faces against the block 4 forming the counter-needle so that the needle 3 is not superimposed above the block 4 forming the counter-needle and does not interfere with the accessibility of this block 4 for a worker. Also, accessibility to the block 4 forming the counter-needle is not hampered by the needle 3.

[0016] Selon un exemple de réalisation de l’ensemble de l’invention la fonction de contre-aiguille est réalisée par au moins deux blocs 4 juxtaposés dans le prolongement l’un de l’autre et montés sur une même structure monobloc 2 de façon à réaliser au moins une continuité de surfaces de roulement portées successivement par les différents blocs 4. Selon une particularité préférée de construction de la structure monobloc, les différents blocs 4 qui se succèdent présentent également une continuité au niveau des surfaces des différents blocs 4 successifs destinées à être en contact avec l’aiguille 3 de l’appareil de voie. [0017] Selon un exemple de réalisation de l’ensemble de l’invention, la structure monobloc 2 comprend un logement 5 de forme complémentaire au bloc 4 formant le contre-aiguille, configuré pour y permettre le positionnement du bloc 4 par insertion. Il convient de relever que la structure monobloc 2 qui intègre un logement 5 destiné à recevoir un bloc 4 amovible formant le contre-aiguille comprend, en amont et en aval du logement 5, des surfaces de roulement destinées à interagir avec les roues d’un véhicule en déplacement. Par ailleurs, cette structure monobloc 2 illustrée et dénommée « monobloc » est susceptible d’être réalisée sous la forme d’un élément de matière structurellement unitaire ou alternativement sous la forme de plusieurs pièces assemblées, voire soudées, entre elles tout en demeurant dans le domaine de l'invention revendiquée. Selon une particularité, lorsque la fonction de contre-aiguille est remplie par plusieurs blocs 4, les différents blocs 4 sont adaptés pour partager un même logement 5. According to an exemplary embodiment of the assembly of the invention the counter-needle function is performed by at least two blocks 4 juxtaposed in the extension of one another and mounted on the same single-piece structure 2 of so as to achieve at least one continuity of rolling surfaces carried successively by the different blocks 4. According to a preferred feature of construction of the one-piece structure, the different blocks 4 which follow one another also have continuity at the level of the surfaces of the different successive blocks 4 intended to be in contact with needle 3 of the switchgear. According to an exemplary embodiment of the assembly of the invention, the one-piece structure 2 comprises a housing 5 of complementary shape to the block 4 forming the counter-needle, configured to allow the positioning of the block 4 by insertion therein. It should be noted that the one-piece structure 2 which incorporates a housing 5 intended to receive a removable block 4 forming the counter-needle comprises, upstream and downstream of the housing 5, rolling surfaces intended to interact with the wheels of a moving vehicle. Furthermore, this one-piece structure 2 illustrated and called "one-piece" is capable of being produced in the form of an element of structurally unitary material or alternatively in the form of several parts assembled, or even welded, together while remaining in the structure. field of the claimed invention. According to a particular feature, when the counter-needle function is fulfilled by several blocks 4, the different blocks 4 are adapted to share the same housing 5.

[0018] Selon une construction particulière de ce logement 5, celui-ci est réalisé dans la structure monobloc 2 de façon à présenter au moins une ouverture vers le haut et en direction de l’aiguille 3 montée sur la structure monobloc 2. Une telle construction du logement 5 permet ainsi d’y opérer le positionnement d’un bloc 4 formant le contre-aiguille qui comprend, d’une part, une première surface qui forme une surface de roulement accessible par le dessus pour entrer en contact avec une roue d’un véhicule ferroviaire et, d’autre part, une seconde surface qui forme une surface de contact pour le boudin d’une roue de véhicule ou une butée pour une surface de l’aiguille 3 en appui contre le bloc 4 formant le contre-aiguille. Selon une mise en oeuvre de cet exemple particulier, la structure monobloc 2 comprend, d’une part, une embase 2a sur laquelle repose, directement ou indirectement, l’aiguille 3 montée mobile et, d’autre part, une portion 2b positionnée latéralement à l’embase 2a et qui dépasse au-dessus de celle-ci. Selon un arrangement préféré, la surface de la portion latérale 2b de la structure monobloc 2 qui surmonte la surface supérieure de l’embase 2a est disposée de façon à faire face à la surface de butée de l’aiguille 3 mobile sur la structure monobloc 2. Le logement 5 est ainsi réalisé de façon à comporter au moins une surface de la portion latérale 2b de la structure monobloc 2 et une surface de l’embase 2a, de sorte que ces deux surfaces 2a, 2b réalisent entre elles une concavité configurée et destinée à recevoir le bloc 4 amovible formant le contre-aiguille. Selon une mise en oeuvre préférée de la construction de ce logement 5, la portion latérale 2b et l’embase 2a sont disposées de telle sorte que l’insertion du bloc 4 formant le contre-aiguille dans le logement 5 puisse être effectuée en faisant intervenir une translation opérée selon un déplacement sensiblement vertical et/ou selon un déplacement sensiblement horizontal. According to a particular construction of this housing 5, it is made in the one-piece structure 2 so as to have at least one opening upwards and in the direction of the needle 3 mounted on the one-piece structure 2. Such a construction of the housing 5 thus makes it possible to operate therein the positioning of a block 4 forming the counter-needle which comprises, on the one hand, a first surface which forms a running surface accessible from above to come into contact with a wheel of a rail vehicle and, on the other hand, a second surface which forms a contact surface for the flange of a vehicle wheel or a stop for a surface of the needle 3 bearing against the block 4 forming the counter -needle. According to an implementation of this particular example, the one-piece structure 2 comprises, on the one hand, a base 2a on which rests, directly or indirectly, the mobile mounted needle 3 and, on the other hand, a portion 2b positioned laterally. to the base 2a and which protrudes above it. According to a preferred arrangement, the surface of the lateral portion 2b of the one-piece structure 2 which surmounts the upper surface of the base 2a is arranged so as to face the abutment surface of the moving needle 3 on the one-piece structure 2. The housing 5 is thus made so as to include at least one surface of the lateral portion 2b of the one-piece structure 2 and one surface of the base 2a, so that these two surfaces 2a, 2b form a concavity configured and intended to receive the removable block 4 forming the counter-needle. According to a preferred embodiment of the construction of this housing 5, the lateral portion 2b and the base 2a are arranged so that the insertion of the block 4 forming the counter-needle in the housing 5 can be carried out by involving a translation carried out according to a substantially vertical displacement and / or according to a substantially horizontal displacement.

[0019] Selon une spécificité de réalisation de l’exemple particulier précédemment décrit de l’ensemble de l’invention, l’ensemble comprend au moins un dispositif de retenue verticale et/ou horizontale du bloc 4 formant le contre-aiguille positionné dans le logement 5. Ce dispositif intégré à l’ensemble de l’invention, en fonction de sa construction, assure ainsi tout ou une partie du maintien du bloc 4 formant le contre-aiguille en position dans le logement 5 dédié de la structure monobloc 2. Ce maintien évite ainsi le détachement du bloc 4 formant le contre-aiguille par rapport à la structure monobloc 2 selon au moins un axe de déplacement. According to a specific embodiment of the particular example described above of the assembly of the invention, the assembly comprises at least one vertical and / or horizontal retaining device of the block 4 forming the counter-needle positioned in the housing 5. This device integrated into the assembly of the invention, depending on its construction, thus ensures all or part of the retention of the block 4 forming the counter-needle in position in the dedicated housing 5 of the one-piece structure 2. This maintenance thus prevents the detachment of the block 4 forming the counter-needle relative to the one-piece structure 2 along at least one axis of movement.

[0020] Selon un premier exemple de réalisation de ce dispositif de retenue, celui-ci est réalisé de sorte que la structure monobloc 2 comprend un relief 6 disposé au niveau d’une surface du logement 5 et destiné à interagir avec une surface du bloc 4 formant le contre-aiguille. Selon la surface du logement 5 qui porte ce relief 6 et qui interagit avec le bloc 4 formant le contre-aiguille, l’axe de blocage du déplacement du bloc 4 est susceptible de différer. Aussi, le relief 6 est disposé de façon à coopérer avec une partie du bloc 4 formant le contre-aiguille pour s’opposer à un déplacement selon au moins un plan vertical ou horizontal. Ce relief 6 est susceptible de prendre la forme d’un téton ou d’une structure axiale arrangée pour coopérer avec une forme sensiblement complémentaire portée par le bloc 4 formant le contre-aiguille. According to a first embodiment of this retaining device, the latter is made so that the one-piece structure 2 comprises a relief 6 disposed at a surface of the housing 5 and intended to interact with a surface of the block 4 forming the counter-needle. Depending on the surface of the housing 5 which bears this relief 6 and which interacts with the block 4 forming the counter-needle, the axis of blocking the movement of the block 4 is likely to differ. Also, the relief 6 is arranged so as to cooperate with a part of the block 4 forming the counter-needle to oppose a movement along at least one vertical or horizontal plane. This relief 6 is capable of taking the form of a stud or of an axial structure arranged to cooperate with a substantially complementary shape carried by the block 4 forming the counter-needle.

[0021] Selon un autre exemple de réalisation susceptible d’être combiné avec le premier exemple, le dispositif de retenue fait intervenir un relief 6 positionné en bordure d’une surface du logement 5. Ainsi, le dispositif de retenue positionné au niveau d’un bord supérieur du logement 5 de la structure monobloc 2 comprend une lèvre de blocage 6 de la translation verticale d’un bloc 4 formant le contre-aiguille positionné dans le logement 5. Cette lèvre 6 réalise ainsi un dépassement du bord supérieur de la portion latérale 2b de la structure monobloc 2 de façon à être positionnée au-dessus de la surface supérieure de l’embase 2a. Aussi, l’espace séparant la face inférieure de la lèvre 6 et la face supérieure de l’embase 2a définit une partie du volume du logement 5 pour l’insertion du bloc 4 formant le contre-aiguille. La distance qui sépare la face inférieure de la lèvre 6 et la face supérieure de l’embase 2a correspond sensiblement à la hauteur du bloc 4 formant le contre-aiguille au niveau de sa portion d’insertion. Selon une mise en oeuvre particulière de cette lèvre 6 dans l’ensemble de l’invention, cette lèvre 6 est disposée au niveau de toute la longueur du bord supérieur de la portion latérale 2b de la structure monobloc 2, de sorte que tout déplacement vertical du bloc 4 formant le contre-aiguille inséré dans le logement 5 de la structure monobloc 2 soit empêché. Toutefois, selon une alternative à cette mise en oeuvre particulière, la lèvre 6 est réalisée de façon discontinue au niveau d’au moins deux points espacés du bord supérieur de la portion latérale 2b de la structure monobloc 2. Selon une alternative de mise en oeuvre, une lèvre de blocage est positionnée en périphérie de l’embase 2a pour s’opposer à une translation horizontale du bloc 4 formant le contre- aiguille par rapport au logement 5. According to another exemplary embodiment capable of being combined with the first example, the retaining device involves a relief 6 positioned on the edge of a surface of the housing 5. Thus, the retaining device positioned at the level of an upper edge of the housing 5 of the one-piece structure 2 comprises a lip 6 for blocking the vertical translation of a block 4 forming the counter-needle positioned in the housing 5. This lip 6 thus protrudes from the upper edge of the portion side 2b of the one-piece structure 2 so as to be positioned above the upper surface of the base 2a. Also, the space between the lower face of the lip 6 and the upper face of the base 2a defines part of the volume of the housing 5 for the insertion of the block 4 forming the counter-needle. The distance between the lower face of the lip 6 and the upper face of the base 2a corresponds substantially to the height of the block 4 forming the counter-needle at its insertion portion. According to a particular implementation of this lip 6 in the whole of the invention, this lip 6 is arranged at the level of the entire length of the upper edge of the lateral portion 2b of the one-piece structure 2, so that any vertical displacement of the block 4 forming the counter-needle inserted into the housing 5 of the one-piece structure 2 is prevented. However, according to an alternative to this particular implementation, the lip 6 is produced discontinuously at the level of at least two points spaced from the upper edge of the lateral portion 2b of the one-piece structure 2. According to an alternative implementation , a locking lip is positioned on the periphery of the base 2a to oppose a horizontal translation of the block 4 forming the counter-needle relative to the housing 5.

[0022] Selon un autre exemple de réalisation susceptible d’être combiné avec au moins un des deux autres exemples précédemment décrits, le dispositif de retenue fait intervenir une pièce de fixation, telle un tire-fond ou une vis, qui maintient assemblé le bloc 4 formant le contre-aiguille avec la structure monobloc en traversant au moins l’un de ces deux éléments. Selon une première variante de cet exemple, la structure monobloc 2 est traversée de part en part au niveau d’un alésage dédié par la pièce de fixation pour coopérer avec un alésage taraudé du bloc 4 formant le contre-aiguille. Selon une variante alternative de cet exemple, la pièce de fixation traverse le contre-aiguille 4 de part en part au niveau d’un alésage dédié pour coopérer avec un alésage taraudé de la structure monobloc 2. Selon une autre variante de cet exemple, la pièce de fixation traverse le bloc 4 formant le contre-aiguille et la structure monobloc 2 de part en part de sorte que le bloc 4 et la structure monobloc 2 soient pris en tenaille entre la tête de la pièce de fixation et une pièce associée tel un boulon. According to another exemplary embodiment capable of being combined with at least one of the other two examples described above, the retaining device involves a fastener, such as a lag bolt or a screw, which keeps assembled the block 4 forming the counter-needle with the one-piece structure by passing through at least one of these two elements. According to a first variant of this example, the one-piece structure 2 is traversed right through at the level of a dedicated bore by the fixing part to cooperate with a threaded bore of the block 4 forming the counter-needle. According to an alternative variant of this example, the fastening piece passes right through the counter-needle 4 at the level of a dedicated bore to cooperate with a threaded bore of the one-piece structure 2. According to another variant of this example, the fastening piece passes through block 4 forming the counter-needle and the one-piece structure 2 right through so that the block 4 and the one-piece structure 2 are gripped between the head of the fastening piece and an associated piece such as a bolt.

[0023] Selon un autre exemple de réalisation susceptible d’être combiné avec au moins un des trois autres exemples précédemment décrits, le dispositif de retenue fait intervenir une construction particulière de la complémentarité du bloc 4 formant le contre-aiguille avec la structure monobloc 2. Ainsi, dans un plan sensiblement horizontal, au moins une première extrémité du bloc 4 formant le contre-aiguille présente une construction de forme convexe en pointe arrangée pour coopérer avec une extrémité de forme complémentaire concave 2d du logement 5 porté par la structure monobloc 2. Selon une préférence de mise en oeuvre de cet exemple particulier, la concavité 2d de l’extrémité du logement 5 est réalisée pour être portée par la portion latérale 2b de la structure monobloc 2 qui dépasse en hauteur la surface supérieure de l’embase 2a de cette structure monobloc 2. Selon une autre préférence complémentaire de mise en oeuvre de cet exemple particulier, la concavité 2d du logement 5 est arrangée pour entourer l’extrémité du bloc 4 formant le contre-aiguille au niveau de plusieurs de ses faces. Ainsi, l’extrémité concave du logement 5 interagit avec la pointe du bloc 4 formant le contre-aiguille, d’une part, au niveau de l’extrémité de sa pointe et, d’autre part, au niveau de chacune des faces latérales de l’extrémité du bloc 4 formant le contre-aiguille ou d’une composante de ces faces latérales de l’extrémité. Selon une préférence de construction, la partie de la pointe positionnée au niveau de l’extrémité de la face latérale du bloc 4 destinée à faire face à l’aiguille 3, réalise un angle avec la face latérale compris entre 0° et 90°, préférentiellement compris entre 35° et 60°, idéalement de l’ordre de 45° pour présenter la forme d’un chanfrein dans un plan horizontal. Cet arrangement convexe de l’extrémité du bloc 4 formant le contre-aiguille permet, d’une part, une insertion du bloc 4 dans le logement 5 qui se trouve facilitée lorsqu’elle est effectuée au niveau de cette première extrémité préalablement au positionnement du reste du corps du bloc 4 formant le contre-aiguille dans le logement 5 et, d’autre part, un blocage du bloc 4 inséré selon une direction différente du plan horizontal. According to another exemplary embodiment capable of being combined with at least one of the other three examples described above, the retaining device involves a particular construction of the complementarity of the block 4 forming the counter-needle with the one-piece structure 2 Thus, in a substantially horizontal plane, at least a first end of the block 4 forming the counter-needle has a construction of convex shape at a point arranged to cooperate with an end of concave complementary shape 2d of the housing 5 carried by the one-piece structure 2. According to an implementation preference of this particular example, the concavity 2d of the end of the housing 5 is made to be carried by the lateral portion 2b of the one-piece structure 2 which exceeds in height the upper surface of the base 2a. of this one-piece structure 2. According to another complementary preference for implementing this particular example, the concavity 2d of the housing 5 is a rrangée to surround the end of the block 4 forming the counter-needle at the level of several of its faces. Thus, the concave end of the housing 5 interacts with the point of the block 4 forming the counter-needle, on the one hand, at the level of the end of its point and, on the other hand, at the level of each of the lateral faces. the end of the block 4 forming the counter-needle or a component of these side faces of the end. According to a construction preference, the part of the point positioned at the level of the end of the lateral face of the block 4 intended to face the needle 3, makes an angle with the lateral face of between 0 ° and 90 °, preferably between 35 ° and 60 °, ideally of the order of 45 ° to have the shape of a chamfer in a horizontal plane. This convex arrangement of the end of the block 4 forming the counter-needle allows, on the one hand, an insertion of the block 4 into the housing 5 which is facilitated when it is carried out at this first end prior to the positioning of the rest of the body of the block 4 forming the counter-needle in the housing 5 and, on the other hand, a blocking of the block 4 inserted in a direction different from the horizontal plane.

[0024] Selon un exemple complémentaire à cet exemple de mise en oeuvre particulier d’une concavité 2d au niveau de l’extrémité du logement 5 destinée à recevoir la première extrémité du bloc 4 formant le contre-aiguille, la seconde extrémité du bloc 4 présente une construction réalisant un chanfrein ou un biseau dans un plan horizontal et destiné à coopérer avec un arrangement complémentaire 2e formé, au niveau de l’extrémité du logement 5, par une surface dédiée de la portion latérale 2b de la structure monobloc 2. Selon une préférence de construction, l’angle du biseau avec la face latérale du bloc 4 est compris entre 0° et 90°, préférentiellement compris entre 35° et 60°, idéalement de l’ordre 45°. Cet arrangement permet alors à la surface dédiée 2e de la structure monobloc 2 de remplir la fonction de rampe de glissement qui par réaction translate le bloc 4 formant le contre- aiguille en direction de l’extrémité concave du logement 5 lorsque la seconde extrémité en biseau du bloc 4 est appuyée, dans un plan horizontal, contre la surface dédiée du logement 5. Un avantage de la réalisation d’un bloc 4 formant le contre-aiguille dont les extrémités présentent des arrangements différents et respectivement complémentaires du logement 5 porté par la structure monobloc 2 est d’imposer un sens d’insertion unique du bloc 4 formant le contre-aiguille dans son logement 5 et d’éviter en conséquence un assemblage erroné de l’ensemble selon l’invention. According to a complementary example to this particular example of implementation of a concavity 2d at the end of the housing 5 intended to receive the first end of the block 4 forming the counter-needle, the second end of the block 4 presents a construction making a chamfer or a bevel in a horizontal plane and intended to cooperate with a complementary arrangement 2e formed, at the level of the end of the housing 5, by a dedicated surface of the lateral portion 2b of the one-piece structure 2. According to one construction preference, the angle of the bevel with the lateral face of the block 4 is between 0 ° and 90 °, preferably between 35 ° and 60 °, ideally of the order of 45 °. This arrangement then allows the dedicated surface 2e of the one-piece structure 2 to fulfill the function of a sliding ramp which by reaction translates the block 4 forming the counter-needle in the direction of the concave end of the housing 5 when the second bevelled end of the block 4 is pressed, in a horizontal plane, against the dedicated surface of the housing 5. An advantage of the production of a block 4 forming the counter-needle, the ends of which have different and respectively complementary arrangements of the housing 5 carried by the monoblock structure 2 is to impose a single insertion direction of block 4 forming the counter-needle in its housing 5 and consequently to avoid incorrect assembly of the assembly according to the invention.

[0025] Selon un autre exemple de réalisation susceptible d’être combiné avec les quatre autres exemples précédemment décrits, le dispositif de retenue fait intervenir une pièce de blocage 7 configurée pour être fixée directement ou indirectement à la structure monobloc 2 et comprenant au moins une surface d’appui 7a destinée à interagir avec une surface du bloc 4 formant le contre-aiguille de façon à presser le bloc 4 contre la structure monobloc 2. La pièce de blocage 7 comprend une interface 7b de fixation sur la structure monobloc 2, par exemple au niveau de la surface supérieure de l’embase 2a. Selon une préférence de mise en oeuvre non-limitative de l’invention, la pièce de blocage 7 est arrangée de sorte que l’interface 7b de fixation coopère avec la surface supérieure de l’embase 2a de la structure monobloc 2. Selon un exemple, la fixation de la pièce de blocage 7 fait intervenir une pièce, telle un tire-fond ou une vis, qui traverse la pièce de blocage 7 de part en part au niveau d’un alésage dédié depuis une partie de la surface supérieure de la pièce de blocage 7 pour coopérer avec un alésage taraudé de la structure monobloc 2. Cette insertion de la pièce de fixation au niveau de la surface supérieure de la pièce de blocage 7 autorise un accès facilité pour l’utilisateur ou l’intervenant sur le site lorsqu’il est nécessaire de détacher la pièce de blocage 7 de la structure monobloc 2 pour libérer le bloc 4 formant le contre-aiguille du logement 5 de la structure monobloc 2. Par ailleurs, la pièce de blocage 7 est arrangée pour être montée et fixée sur la structure monobloc 2 de sorte que la surface supérieure de cette pièce monobloc 7 n’impacte pas le déplacement d’une roue de véhicule sur la surface de roulement du bloc 4 et notamment le bord périphérique du boudin d’une roue en déplacement le long d’une face latérale du bloc 4 formant le contre-aiguille. Pour ce faire et selon un arrangement préféré, la pièce de blocage 7 est positionnée en appui contre une surface du bloc 4 formant le contre-aiguille à distance de la surface de roulement du bloc 4, de sorte que la distance entre la surface de roulement du bloc 4 et la surface supérieure de la pièce de blocage 7 soit supérieure à la hauteur du boudin d’une roue de véhicule ferroviaire destiné à se déplacer sur un appareil de voie 10 intégrant un ensemble selon l’invention. According to another exemplary embodiment capable of being combined with the other four examples described above, the retaining device involves a locking part 7 configured to be fixed directly or indirectly to the monobloc structure 2 and comprising at least one bearing surface 7a intended to interact with a surface of the block 4 forming the counter-needle so as to press the block 4 against the one-piece structure 2. The locking part 7 comprises an interface 7b for fixing to the one-piece structure 2, by example at the upper surface of the base 2a. According to a non-limiting implementation preference of the invention, the locking part 7 is arranged so that the fixing interface 7b cooperates with the upper surface of the base 2a of the one-piece structure 2. According to one example. , the fixing of the locking part 7 involves a part, such as a lag screw or a screw, which passes right through the locking part 7 at the level of a dedicated bore from part of the upper surface of the locking part 7 to cooperate with a threaded bore of the one-piece structure 2. This insertion of the fastening part at the level of the upper surface of the locking part 7 allows easy access for the user or the worker on the site when it is necessary to detach the blocking piece 7 from the one-piece structure 2 to release the block 4 forming the counter-needle from the housing 5 of the one-piece structure 2. Furthermore, the blocking piece 7 is arranged to be mounted and fixed on the monob structure loc 2 so that the upper surface of this one-piece part 7 does not impact the movement of a vehicle wheel on the running surface of the block 4 and in particular the peripheral edge of the flange of a wheel moving along a lateral face of the block 4 forming the counter-needle. To do this and according to a preferred arrangement, the locking piece 7 is positioned resting against a surface of the block 4 forming the counter-needle at a distance from the rolling surface of the block 4, so that the distance between the rolling surface of the block 4 and the upper surface of the locking part 7 is greater than the height of the flange of a rail vehicle wheel intended to move on a track device 10 incorporating an assembly according to the invention.

[0026] Selon une spécificité de réalisation de cet exemple particulier, la pièce de blocage 7 est configurée pour empêcher la translation du bloc 4 formant le contre-aiguille selon au moins un axe horizontal. Selon un arrangement préféré de cette spécificité de réalisation, la surface d’appui 7a de la pièce de blocage 7 est configurée pour faire face à la portion latérale 2b de la structure monobloc 2. Cet arrangement permet la prise en tenaille, voire le pincement, du bloc 4 formant le contre-aiguille dans un plan sensiblement horizontal entre, d’une part, la surface d’appui 7a de la pièce de blocage 7 et, d’autre part, une surface du logement 5 formée par la portion latérale 2b de la structure monobloc 2. Selon une spécificité complémentaire de mise en oeuvre proposée à titre d’exemple, la structure monobloc 2 comprend une portion supplémentaire 2c configurée pour réaliser une butée pour la pièce de blocage 7 dans un plan horizontal au niveau d’une surface d’appui 7c, de sorte que la pièce de blocage 7 et le bloc 4 formant le contre-aiguille sont positionnées entre deux portions de la structure monobloc 2 que sont, d’une part, la portion latérale 2b et, d’autre part, la portion supplémentaire 2c. According to a specific embodiment of this particular example, the locking part 7 is configured to prevent the translation of the block 4 forming the counter-needle along at least one horizontal axis. According to a preferred arrangement of this specificity of embodiment, the bearing surface 7a of the locking part 7 is configured to face the lateral portion 2b of the one-piece structure 2. This arrangement allows gripping, or even pinching, of the block 4 forming the counter-needle in a substantially horizontal plane between, on the one hand, the bearing surface 7a of the locking part 7 and, on the other hand, a surface of the housing 5 formed by the lateral portion 2b of the one-piece structure 2. According to an additional specificity of implementation proposed by way of example, the one-piece structure 2 comprises an additional portion 2c configured to produce a stop for the locking part 7 in a horizontal plane at the level of a bearing surface 7c, so that the blocking part 7 and the block 4 forming the counter-needle are positioned between two portions of the one-piece structure 2 which are, on the one hand, the lateral portion 2b and, on the other hand part, the supplement portion area 2c.

[0027] Selon un exemple spécifique complémentaire de réalisation de la pièce de blocage 7, cette pièce 7 comprend, au niveau de sa surface d’appui 7a destinée à interagir avec le bloc 4 formant le contre-aiguille, une pente de sorte que la surface d’appui 7a réalise une rampe dont l’avancée au niveau supérieur est plus importante que l’avancée au niveau inférieur. Cette rampe de la surface d’appui 7a est configurée pour interagir avec une surface complémentaire du bloc 4 formant le contre-aiguille de sorte que les forces de déplacement verticales du contre-aiguille 4 génèrent une composante horizontale au niveau de la pièce de blocage 7. Aussi, le bloc 4 formant le contre-aiguille se trouve également bloqué en translation verticale par la pièce de blocage 7 par la réalisation de cette surface d’appui 7a sous la forme d’une rampe ou d’une surface inclinée. According to a complementary specific example of embodiment of the locking part 7, this part 7 comprises, at its bearing surface 7a intended to interact with the block 4 forming the counter-needle, a slope so that the bearing surface 7a produces a ramp whose projection at the upper level is greater than the projection at the lower level. This ramp of the bearing surface 7a is configured to interact with a complementary surface of the block 4 forming the counter-needle so that the vertical displacement forces of the counter-needle 4 generate a horizontal component at the level of the locking part 7 Also, the block 4 forming the counter-needle is also blocked in translation. vertical by the blocking part 7 by producing this bearing surface 7a in the form of a ramp or an inclined surface.

[0028] Selon un autre exemple particulier de réalisation de l’ensemble de l’invention complémentaire des exemples précédemment détaillés, la pièce de blocage 7 est configurée pour interagir au niveau d’au moins une des extrémités du bloc 4 formant le contre-aiguille. En combinaison avec la mise en oeuvre d’une concavité au niveau de l’extrémité du logement 5 destinée à recevoir la première extrémité du bloc 4 formant le contre-aiguille, la pièce de blocage 7 est préférentiellement positionnée au niveau de la seconde extrémité du logement 5 de sorte que, dans un plan horizontal, le bloc 4 formant le contre-aiguille se trouve maintenu en position dans le logement 5 de la structure monobloc 2 grâce à un blocage en deux points du bloc 4, à savoir, d’une part, au niveau de l’interaction concave/convexe du logement 5 et, d’autre part, au niveau de la pièce de blocage 7. According to another particular embodiment of the assembly of the invention complementary to the previously detailed examples, the locking part 7 is configured to interact at at least one of the ends of the block 4 forming the counter-needle . In combination with the implementation of a concavity at the level of the end of the housing 5 intended to receive the first end of the block 4 forming the counter-needle, the locking piece 7 is preferably positioned at the level of the second end of the needle. housing 5 so that, in a horizontal plane, the block 4 forming the counter-needle is held in position in the housing 5 of the one-piece structure 2 thanks to a two-point locking of the block 4, namely, a on the one hand, at the level of the concave / convex interaction of the housing 5 and, on the other hand, at the level of the locking part 7.

[0029] Selon un autre exemple particulier de réalisation de l’ensemble de l’invention complémentaire des exemples précédemment détaillés, au moins une surface du bloc 4 formant le contre-aiguille destinée à être en appui contre la structure monobloc 2 comprend au moins un logement 8 configuré pour intégrer un élément de chauffage 9. Selon une mise en oeuvre préférée, ce logement 8 est réalisé sous la forme d’un alésage dans l’épaisseur du bloc 4 formant le contre-aiguille qui comporte un orifice au niveau de la surface du bloc 4 destinée à être en contact contre la structure monobloc 2. Préférentiellement, l’orifice de ce logement 8 est porté par la surface destinée à interagir avec une surface de la portion latérale 2b de la structure monobloc 2. Toutefois, la position de ce logement 8 dans l’épaisseur du bloc 4 formant le contre-aiguille est susceptible d’être adaptée en fonction de la position et de l’encombrement spécifique de l’élément de chauffage 9. According to another particular embodiment of the assembly of the invention complementary to the previously detailed examples, at least one surface of the block 4 forming the counter-needle intended to bear against the one-piece structure 2 comprises at least one housing 8 configured to integrate a heating element 9. According to a preferred embodiment, this housing 8 is produced in the form of a bore in the thickness of the block 4 forming the counter-needle which comprises an orifice at the level of the surface of the block 4 intended to be in contact against the one-piece structure 2. Preferably, the orifice of this housing 8 is carried by the surface intended to interact with a surface of the lateral portion 2b of the one-piece structure 2. However, the position of this housing 8 in the thickness of the block 4 forming the counter-needle is capable of being adapted as a function of the position and of the specific size of the heating element 9.

[0030] Selon un autre exemple particulier de réalisation de l’ensemble de l’invention complémentaire des exemples précédemment détaillés, le bloc 4 formant le contre-aiguille est réalisé à partir d’un acier de plus grande résistance que l’acier de la structure monobloc 2. Aussi, l’ensemble de l’invention comprenant un bloc 4 formant le contre-aiguille structurellement indépendant de la structure monobloc 2 qui le porte autorise d’adapter le matériau de construction à la fonction de la pièce ou de l’élément particulier qui participe à l’ensemble de l’invention. Cette adaptation permet, d’une part, une combinaison de matériaux différents aux propriétés spécifiques et, d’autre part, de limiter l’utilisation de matériaux dont les coûts de production sont plus élevés aux seuls éléments au niveau desquels ils sont nécessaires, voire indispensables. Ainsi, le bloc 4 formant le contre-aiguille qui est conduit à supporter, notamment au niveau de sa surface de roulement, des efforts plus importants en raison de passages répétés de roues de véhicules est réalisé dans un matériau mieux adapté à de telles contraintes, par exemple un acier ou un alliage haute résistance ou présentant une facilité de soudure améliorée, que ne l’est la structure monobloc 2 qui réalise la structure support de l’ensemble de l’invention réalisée dans un acier moins noble tel que, à titre d’exemple, le S355 JO. According to another particular embodiment of the assembly of the invention complementary to the previously detailed examples, the block 4 forming the counter-needle is made from a steel of greater strength than the steel of the one-piece structure 2. Also, the assembly of the invention comprising a block 4 forming the counter-needle structurally independent of the one-piece structure 2 which carries it allows the construction material to be adapted to the function of the particular part or element which contributes to the whole of the invention. This adaptation allows, on the one hand, a combination of different materials with specific properties and, on the other hand, to limit the use of materials whose production costs are higher to only those elements for which they are necessary, even indispensable. Thus, the block 4 forming the counter-needle which is made to withstand, in particular at the level of its running surface, greater forces due to repeated passages of vehicle wheels is made of a material better suited to such constraints, for example a steel or a high resistance alloy or having an improved ease of welding, than is the one-piece structure 2 which produces the support structure of the assembly of the invention made in a less noble steel such as, by way of example, the S355 JO.

[0031] L’invention porte également sur un appareil de voie 10 de type aiguillage qui intègre au moins un ensemble selon l’invention. Préférentielle, l’appareil de voie 10 intègre un ensemble au niveau de chacune des lignes de rails d’un branchement d’une voie ferrée. Cet ensemble selon l’invention est ainsi intégré au niveau d’un appareil de voie 10 pour former un demi- aiguillage 1 . Aussi, l’ensemble de l’invention est doublé dans le cadre d’un appareil de voie 10 selon l’invention. Un exemple d’appareil de voie selon l’invention est notamment illustré de façon schématique par la figure 7. The invention also relates to a switch-type track apparatus 10 which incorporates at least one assembly according to the invention. Preferably, the track apparatus 10 integrates an assembly at each of the rail lines of a branch of a railway track. This assembly according to the invention is thus integrated at the level of a switchgear 10 to form a half-switch 1. Also, the whole of the invention is doubled as part of a switchgear 10 according to the invention. An example of a switchgear according to the invention is particularly illustrated schematically in Figure 7.

[0032] Dans le cadre de la substitution d’un bloc 4 formant le contre- aiguille au niveau d’un ensemble d’un appareil de voie 10 selon l’invention, l’intervenant opère : [0032] As part of the substitution of a block 4 forming the counter-needle at the level of an assembly of a track apparatus 10 according to the invention, the intervenor operates:

- un déplacement de l’aiguille 3 par rapport au bloc 4 de façon à écarter ces deux éléments, - un retrait de la pièce de blocage 7 de la structure monobloc 2 sur laquelle elle est montée, - a movement of the needle 3 relative to the block 4 so as to separate these two elements, - removal of the blocking part 7 from the one-piece structure 2 on which it is mounted,

- un retrait du bloc 4 formant le contre-aiguille du logement 5 de la structure monobloc 2, - a withdrawal of the block 4 forming the counter-needle of the housing 5 of the one-piece structure 2,

- une insertion d’un nouveau bloc 4 de substitution formant le contre- aiguille dans le logement 5 de la structure monobloc 2, - insertion of a new substitution block 4 forming the counter-needle in the housing 5 of the one-piece structure 2,

- un verrouillage du bloc 4 de substitution dans le logement 5 par positionnement de la pièce de blocage 7 contre le bloc 4 et sa fixation à la structure monobloc 2. - A locking of the substitution block 4 in the housing 5 by positioning the locking part 7 against the block 4 and its attachment to the one-piece structure 2.

[0033] Lorsque l’ensemble selon l’invention intègre des éléments de chauffage, l’intervenant procède, d’une part, à la dépose des éléments de chauffage précédemment à l’étape de déplacement de l’aiguille 3 et, d’autre part, à la remise en place de ces éléments de chauffage en fin de procédé. When the assembly according to the invention incorporates heating elements, the practitioner proceeds, on the one hand, to the removal of the heating elements previously to the step of moving the needle 3 and, of on the other hand, when these heating elements are replaced at the end of the process.

[0034] De façon plus particulière, l’insertion du bloc 4 formant le contre- aiguille dans le logement 5 de la structure monobloc 2 est réalisée en insérant et en calant la première extrémité qui forme la pointe du bloc 4 dans l’extrémité concave 2d du logement 5, puis en insérant le reste du corps du bloc 4 formant le contre-aiguille dans le logement 5 de sorte que la seconde extrémité en biseau du bloc 4 soit également positionnée dans l’arrangement complémentaire 2e du logement 5 de la structure monobloc 2 et que les surfaces de roulement, d’une part, du bloc 4 formant le contre- aiguille et, d’autre part, de la structure monobloc 2 soient positionnées de niveau, de façon à présenter une continuité de surface de roulement. More particularly, the insertion of the block 4 forming the counter-needle in the housing 5 of the one-piece structure 2 is carried out by inserting and wedging the first end which forms the point of the block 4 in the concave end. 2d of the housing 5, then inserting the rest of the body of the block 4 forming the counter-needle into the housing 5 so that the second bevelled end of the block 4 is also positioned in the complementary arrangement 2e of the housing 5 of the structure one-piece 2 and that the rolling surfaces, on the one hand, of the block 4 forming the counter-needle and, on the other hand, of the one-piece structure 2 are positioned level, so as to have a continuity of the rolling surface.
