Description

La présente invention concerne un outil manoeuvrable manuellement pour déplacer un attelage d'un véhicule ferroviaire latéralement par rapport à un châssis du véhicule ferroviaire.The present invention relates to a manually operable tool for moving a coupling of a railway vehicle laterally relative to a chassis of the railway vehicle.

Le document US 357 562 décrit un tel outil. L'outil en question comprend une tige dont l'extrémité est munie d'une fourche. La tige permet à un opérateur d'attraper l'attelage du véhicule ferroviaire et de le déplacer en tirant sur la tige.The document US 357,562 describes such a tool. The tool in question includes a rod whose end is fitted with a fork. The rod allows an operator to grab the rail vehicle's hitch and move it by pulling on the rod.

Toutefois, l'outil tel que décrit requiert de la part de l'opérateur manipulant l'outil d'appliquer un effort de traction conséquent sur l'attelage pour parvenir à le déplacer. L'opération effectuée peut ainsi être difficile pour l'opérateur.However, the tool as described requires the operator handling the tool to apply a significant tractive force on the hitch in order to move it. The operation carried out can therefore be difficult for the operator.

Le document US 3 527 144 A décrit également un outil de ce genre. Le déplacement latéral de l'attelage ferroviaire y est réalisé au moyen d'une vis sans fin, ce qui toutefois requiert une construction complexe.The document US 3,527,144 A also describes a tool of this kind. The lateral movement of the railway coupler is carried out by means of a worm screw, which however requires complex construction.

US 3 227 289 décrit un outil de contrôle d'un élément de verrouillage d'un attelage de véhicule ferroviaire. US 3,227,289 describes a tool for checking a locking element of a railway vehicle coupling.

Un des buts de l'invention est de pallier cet inconvénient en proposant un outil permettant un déplacement aisé de l'attelage avec un entraînement manuel.One of the aims of the invention is to overcome this drawback by proposing a tool allowing easy movement of the hitch with a manual drive.

A cet effet, l'invention concerne un outil selon la revendication 1.For this purpose, the invention relates to a tool according to claim 1.

Grâce à l'outil, il est possible de déplacer l'attelage latéralement par rapport au châssis du véhicule ferroviaire en lui appliquant un effort de traction conséquent par l'intermédiaire du mécanisme d'actionnement, tout en requérant de l'opérateur l'application d'un effort modéré pour entraîner en rotation l'organe de manoeuvre.Thanks to the tool, it is possible to move the coupling laterally in relation to the chassis of the railway vehicle by applying a significant traction force to it via the actuation mechanism, while requiring the operator to apply with a moderate effort to rotate the operating member.

Dans des modes de réalisation particulier, l'outil comprend une ou plusieurs des caractéristiques optionnelles des revendications 2 à 7, prise(s) isolément ou suivant toutes les combinaisons techniquement possibles.In particular embodiments, the tool comprises one or more of the optional characteristics of claims 2 to 7, taken in isolation or in all technically possible combinations.

L'invention concerne également un ensemble selon la revendication 8.The invention also relates to an assembly according to claim 8.

Optionnellement, l'ensemble peut également comprendre les caractéristiques de la revendication 9.Optionally, the assembly can also include the characteristics of claim 9.

L'invention concerne également un procédé d'utilisation d'un outil tel que décrit précédemment, selon la revendication 10.The invention also relates to a method of using a tool as described above, according to claim 10.

L'invention sera mieux comprise à la lecture de la description qui va suivre donnée uniquement à titre d'exemple non limitatif, et faite en se référant aux dessins annexés, sur lesquels :

  • [Fig 1] la figure 1 est une vue schématique en vue de face de l'extrémité de couplage d'un véhicule ferroviaire sur laquelle est installé un outil selon l'invention ; et
  • [Fig 2] la figure 2 est une vue schématique en vue de dessus d'une partie de l'extrémité de couplage illustrée sur la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of non-limiting example, and made with reference to the appended drawings, in which:
  • [ Figure 1 ] there figure 1 is a schematic front view of the coupling end of a railway vehicle on which a tool according to the invention is installed; And
  • [ Figure 2 ] there figure 2 is a schematic top view of part of the coupling end shown in the figure 1 .

En référence aux figures 1 et 2, un ensemble 2 comprend un véhicule ferroviaire 4 et un outil 6.With reference to figures 1 And 2 , a set 2 includes a railway vehicle 4 and a tool 6.

Le véhicule ferroviaire 4 s'étend selon une direction longitudinale parallèle à une direction de marche du véhicule ferroviaire 4. Dans la suite, les termes « longitudinal » et « latéral » s'entendent par référence à la direction longitudinale du véhicule ferroviaire 4.The railway vehicle 4 extends in a longitudinal direction parallel to a direction of travel of the railway vehicle 4. In the following, the terms "longitudinal" and "lateral" are understood with reference to the longitudinal direction of the railway vehicle 4.

Seule une extrémité de couplage 10 du véhicule ferroviaire 4 est visible sur les figures 1 et 2.Only one coupling end 10 of the railway vehicle 4 is visible on the figures 1 And 2 .

Le véhicule ferroviaire 4, également appelé premier véhicule ferroviaire peut être couplé, à son extrémité de couplage 10, avec un autre véhicule ferroviaire également appelé deuxième véhicule ferroviaire (non illustré).The railway vehicle 4, also called the first railway vehicle, can be coupled, at its coupling end 10, with another railway vehicle also called the second railway vehicle (not illustrated).

Pour ce faire, le véhicule ferroviaire 4 comprend, à son extrémité de couplage 10, un attelage 12 pour le couplage avec un attelage de l'autre véhicule ferroviaire.To do this, the railway vehicle 4 comprises, at its coupling end 10, a coupling 12 for coupling with a coupling of the other railway vehicle.

L'attelage 12 est déplaçable latéralement par rapport à un châssis du véhicule ferroviaire 4 pour permettre le passage de courbes lorsque le véhicule ferroviaire 4 est attelé à l'autre véhicule ferroviaire.The coupling 12 can be moved laterally relative to a chassis of the railway vehicle 4 to allow the passage of curves when the railway vehicle 4 is coupled to the other railway vehicle.

Le véhicule ferroviaire 4 comprend, par exemple, au moins un absorbeur de choc 14. Chaque absorbeur de choc 14 est fixé sur le châssis du véhicule ferroviaire 4.The railway vehicle 4 comprises, for example, at least one shock absorber 14. Each shock absorber 14 is fixed on the chassis of the railway vehicle 4.

Chaque absorbeur de choc 14 est destiné à amortir un choc occurrent, par exemple, entre le véhicule ferroviaire 4 et un autre véhicule ferroviaire lors du couplage du véhicule ferroviaire 4 avec cet autre véhicule ferroviaire.Each shock absorber 14 is intended to absorb a shock occurring, for example, between the railway vehicle 4 and another railway vehicle during the coupling of the railway vehicle 4 with this other railway vehicle.

Comme illustré sur la figure 1, le véhicule ferroviaire 4 comprend par exemple deux absorbeurs de choc 14 situés latéralement de part et d'autre de l'attelage 12.As illustrated on the figure 1 , the railway vehicle 4 comprises for example two shock absorbers 14 located laterally on either side of the coupling 12.

L'outil 6 est manoeuvrable manuellement pour déplacer l'attelage 12 du véhicule ferroviaire 4 latéralement par rapport au châssis du véhicule ferroviaire 4, par exemple, en vue de son couplage avec l'attelage de l'autre véhicule ferroviaire.The tool 6 can be operated manually to move the coupling 12 of the railway vehicle 4 laterally relative to the chassis of the railway vehicle 4, for example, with a view to its coupling with the coupling of the other railway vehicle.

L'outil 6 comprend un support 20 configuré pour être fixé sur le châssis du véhicule ferroviaire 4, un mécanisme d'actionnement 18 configuré pour être disposé entre l'attelage 12 et le support 20 fixé sur le châssis du véhicule ferroviaire 4 de manière à agir sur l'attelage 12 et le support 20 pour les rapprocher ou les écarter l'un de l'autre et un organe de manoeuvre 24 monté rotatif autour d'un axe de rotation, la rotation de l'organe de manoeuvre 24 permettant d'entraîner manuellement le mécanisme d'actionnement 18 pour rapprocher ou écarter l'attelage 12 et le support 20 l'un de l'autre.The tool 6 comprises a support 20 configured to be fixed on the chassis of the railway vehicle 4, an actuation mechanism 18 configured to be arranged between the hitch 12 and the support 20 fixed on the chassis of the railway vehicle 4 so as to act on the hitch 12 and the support 20 to bring them closer or further apart from each other and a operating member 24 rotatably mounted around an axis of rotation, the rotation of the operating member 24 making it possible to manually drive the actuating mechanism 18 to bring the hitch 12 and the support 20 closer or apart, one of the other.

Le mécanisme d'actionnement 18 comprend par exemple une tige d'actionnement 22 configurée pour s'étendre entre l'attelage 12 et le support 20 en étant reliée à l'attelage 12 et au support 20. La tige d'actionnement 22 est configurée pour appliquer un effort entre l'attelage 12 et le support 20 pour les rapprocher ou les écarter l'un de l'autre.The actuation mechanism 18 comprises for example an actuation rod 22 configured to extend between the hitch 12 and the support 20 while being connected to the hitch 12 and to the support 20. The actuation rod 22 is configured to apply a force between the hitch 12 and the support 20 to bring them closer or further apart from each other.

Le support 20 est configuré pour être fixé sur le châssis du véhicule ferroviaire 4, par exemple, sur un absorbeur de choc 14.The support 20 is configured to be fixed on the chassis of the railway vehicle 4, for example, on a shock absorber 14.

Le support 20 comprend, par exemple, un corps 30 et un bras 32.The support 20 comprises, for example, a body 30 and an arm 32.

Le corps 30 est configuré pour être fixé au véhicule ferroviaire 4, par exemple, sur un absorbeur de choc 14 du véhicule ferroviaire 4.The body 30 is configured to be fixed to the railway vehicle 4, for example, on a shock absorber 14 of the railway vehicle 4.

Le corps 30 est, par exemple, formé par une platine servant de base pour le bras 32. Lorsque le corps 30 est fixé sur le véhicule ferroviaire 4, il s'étend, par exemple, sensiblement dans un plan vertical perpendiculaire à la direction de marche du véhicule ferroviaire 4.The body 30 is, for example, formed by a plate serving as a base for the arm 32. When the body 30 is fixed on the railway vehicle 4, it extends, for example, substantially in a vertical plane perpendicular to the direction of walking of the railway vehicle 4.

Le bras 32 s'étend depuis le corps 30. Par exemple, lorsque le corps 30 est fixé sur le véhicule ferroviaire 4, le bras 32 s'étend sensiblement dans un plan vertical parallèle à la direction de marche du véhicule ferroviaire 4.The arm 32 extends from the body 30. For example, when the body 30 is fixed on the railway vehicle 4, the arm 32 extends substantially in a vertical plane parallel to the direction of travel of the railway vehicle 4.

Le bras 32 est configuré pour lier la tige d'actionnement 22 au support 20.The arm 32 is configured to connect the actuating rod 22 to the support 20.

Le bras 32 définit par exemple une ouverture 34 (visible sur la figure 2) pour le passage de la tige d'actionnement 22. L'ouverture 34 est par exemple une encoche débouchant sur une surface supérieure du bras 32.The arm 32 defines for example an opening 34 (visible on the figure 2 ) for the passage of the actuating rod 22. The opening 34 is for example a notch opening onto an upper surface of the arm 32.

Le mécanisme d'actionnement 18 comprend un premier organe de liaison 26 et un deuxième organe de liaison 28 disposés sur la tige d'actionnement 22 pour lier la tige d'actionnement 22 respectivement au support 20 et à l'attelage 12, de manière à pouvoir exercer un effort entre l'attelage 12 et le support 20 par l'intermédiaire de la tige d'actionnement 22.The actuating mechanism 18 comprises a first connecting member 26 and a second connecting member 28 arranged on the actuating rod 22 to connect the actuating rod 22 respectively to the support 20 and to the hitch 12, so as to be able to exert a force between the hitch 12 and the support 20 via the actuating rod 22.

La tige d'actionnement 22 s'étend suivant un axe d'extension A-A'.The actuating rod 22 extends along an extension axis A-A'.

Le premier organe de liaison 26 et le deuxième organe de liaison 28 sont mobiles l'un par rapport à l'autre le long de la tige d'actionnement 22 pour rapprocher ou écarter l'attelage 12 et le support 20 l'un de l'autre.The first connecting member 26 and the second connecting member 28 are movable relative to each other along the actuating rod 22 to bring the hitch 12 and the support 20 closer or apart from one another. 'other.

Dans un exemple de réalisation, le premier organe de liaison 26 est configuré pour prendre appui contre le support 20.In an exemplary embodiment, the first connecting member 26 is configured to bear against the support 20.

Ainsi, les efforts de rapprochement ou d'écartement de l'attelage 12 et du support 20 sont transmis au support 20 par l'intermédiaire du premier organe de liaison 26 en appui contre le support 20.Thus, the forces of bringing together or separating the hitch 12 and the support 20 are transmitted to the support 20 via the first connecting member 26 bearing against the support 20.

En particulier, la tige d'actionnement 22 est prévue pour s'étendre à travers l'ouverture 34 du bras 32, le premier organe de liaison 26 prenant appui sur une face du bras 32 tournée à l'opposé de l'attelage 12.In particular, the actuating rod 22 is designed to extend through the opening 34 of the arm 32, the first connecting member 26 bearing on a face of the arm 32 facing away from the hitch 12.

Dans un exemple de réalisation, le premier organe de liaison 26 est mobile le long de la tige d'actionnement 22 pour rapprocher ou écarter l'attelage 12 et le support 20 l'un de l'autre.In an exemplary embodiment, the first connecting member 26 is movable along the actuating rod 22 to bring the hitch 12 and the support 20 closer to or further from each other.

En particulier, le premier organe de liaison 26 et la tige d'actionnement 22 sont munis de filetages complémentaires, de telle sorte que la rotation de la tige d'actionnement 22 autour de son axe d'extension A-A' par rapport au premier organe de liaison 26 provoque le déplacement du premier organe de liaison 26 le long de la tige d'actionnement 22.In particular, the first connecting member 26 and the actuating rod 22 are provided with complementary threads, such that the rotation of the actuating rod 22 around its axis of extension A-A' relative to the first member of connection 26 causes the first connecting member 26 to move along the actuating rod 22.

Dans un exemple de réalisation, l'organe de manoeuvre 24 est couplé à la tige d'actionnement 22 de telle sorte que la rotation de l'organe de manoeuvre 24 provoque la rotation de la tige d'actionnement 22 autour de son axe d'extension A-A'.In an exemplary embodiment, the operating member 24 is coupled to the actuating rod 22 such that the rotation of the operating member 24 causes the rotation of the actuating rod 22 around its axis of extension A-A'.

Lors de la rotation de la tige d'actionnement 22 autour de son axe d'extension A-A', la rotation du premier organe de liaison 26 autour de l'axe d'extension A-A' est bloquée du fait du contact de premier organe de liaison 26 avec le support 20 et/ou bloquée manuellement par l'opérateur.During the rotation of the actuating rod 22 around its extension axis A-A', the rotation of the first connecting member 26 around the extension axis A-A' is blocked due to the contact of the first member connection 26 with the support 20 and/or blocked manually by the operator.

Ainsi, la rotation de l'organe de manoeuvre 24 provoque le déplacement du premier organe de liaison 26 le long de la tige d'actionnement 22.Thus, the rotation of the operating member 24 causes the movement of the first connecting member 26 along the actuating rod 22.

La tige d'actionnement 22 possède une première extrémité 44 et une deuxième extrémité 46.The actuating rod 22 has a first end 44 and a second end 46.

Le deuxième organe de liaison 28 est par exemple disposé à la deuxième extrémité 46 de la tige d'actionnement 22.The second connecting member 28 is for example arranged at the second end 46 of the actuating rod 22.

Le deuxième organe de liaison 28 est par exemple configuré pour s'accrocher à l'attelage 12. Le deuxième organe de liaison 28 présente par exemple la forme d'un crochet configuré pour s'accrocher à un pion de l'attelage 12.The second connecting member 28 is for example configured to hook onto the hitch 12. The second connecting member 28 has for example the shape of a hook configured to hook onto a pin of the hitch 12.

Le deuxième organe de liaison 28 est monté à la deuxième extrémité 46 de la tige d'actionnement 22 en étant rotatif par rapport à la tige d'actionnement 22 autour de l'axe d'extension A-A'.The second connecting member 28 is mounted at the second end 46 of the actuating rod 22 while being rotatable relative to the actuating rod 22 around the extension axis A-A'.

Ainsi, lorsque la tige d'actionnement 22 est lié à l'attelage 12 par l'intermédiaire du deuxième organe de liaison 28, la tige d'actionnement 22 peut pivoter librement autour de son axe d'extension A-A' par rapport à l'attelage 12 tout en restant liée à l'attelage 12 par l'intermédiaire du deuxième élément de liaison 28.Thus, when the actuating rod 22 is linked to the hitch 12 via the second connecting member 28, the actuating rod 22 can pivot freely around its axis of extension AA' relative to the hitch 12 while remaining linked to the hitch 12 via the second connecting element 28.

Dans un exemple de réalisation, le deuxième organe de liaison 28 est fixe en translation le long de la tige d'actionnement 22.In an exemplary embodiment, the second connecting member 28 is fixed in translation along the actuating rod 22.

L'organe de manoeuvre 24 est destiné à être manipulé par un utilisateur désirant déplacer latéralement l'attelage 12 par rapport au châssis du véhicule 4.The operating member 24 is intended to be manipulated by a user wishing to move the hitch 12 laterally relative to the chassis of the vehicle 4.

L'organe de manoeuvre 24 est mobile en rotation autour d'un axe de rotation.The operating member 24 is movable in rotation around an axis of rotation.

La rotation de l'organe de manoeuvre 24 autour de son axe de rotation provoque le déplacement du premier élément de liaison 26 et du deuxième élément de liaison 28 l'un par rapport à l'autre le long de la tige d'actionnement 22.The rotation of the operating member 24 around its axis of rotation causes the first connecting element 26 and the second connecting element 28 to move relative to each other along the actuating rod 22.

Par exemple, comme illustré sur les figures 1 et 2, l'axe de rotation de l'organe de manoeuvre 24 et l'axe d'extension A-A' de la tige d'actionnement 22 sont confondus. L'organe de manoeuvre 24 est mobile en rotation autour de l'axe d'extension A-A' de la tige d'actionnement 22.For example, as illustrated in the figures 1 And 2 , the axis of rotation of the operating member 24 and the extension axis AA' of the actuating rod 22 coincide. The operating member 24 is movable in rotation around the extension axis AA' of the actuating rod 22.

Dans un exemple de réalisation, la rotation de l'organe de manoeuvre 24 entraîne la rotation de la tige d'actionnement 22 autour de son axe d'extension A-A'.In an exemplary embodiment, the rotation of the operating member 24 causes the rotation of the actuating rod 22 around its axis of extension A-A'.

Comme illustré, l'organe de manoeuvre 24 est, par exemple, formé par une manivelle solidaire en rotation de la tige d'actionnement 22.As illustrated, the operating member 24 is, for example, formed by a crank integral in rotation with the actuating rod 22.

L'organe de manoeuvre 24 est par exemple disposé à la première extrémité 44 de la tige d'actionnement 22.The operating member 24 is for example arranged at the first end 44 of the actuating rod 22.

Dans ce qui suit, on décrit un procédé d'utilisation d'un outil 6 tel que décrit précédemment.In what follows, we describe a method of using a tool 6 as described previously.

L'outil 6 est utilisé pour déplacer l'attelage 12 latéralement par rapport au châssis du véhicule ferroviaire 4, par exemple, en vue de son couplage avec l'attelage de l'autre véhicule ferroviaire.The tool 6 is used to move the coupling 12 laterally relative to the chassis of the railway vehicle 4, for example, with a view to its coupling with the coupling of the other railway vehicle.

Ceci peut s'avérer nécessaire lorsque le couplage du véhicule ferroviaire 4 et de l'autre véhicule ferroviaire est effectué dans une courbe de la voie ferroviaire, de sorte que l'attelage 12 du véhicule ferroviaire 4 et celui de l'autre véhicule ferroviaire ne sont pas en regard l'un de l'autre avant leur attelage mutuel.This may prove necessary when the coupling of the railway vehicle 4 and the other railway vehicle is carried out in a curve of the railway track, so that the coupling 12 of the railway vehicle 4 and that of the other railway vehicle does not are not facing each other before their mutual coupling.

L'outil 6 est d'abord positionné sur le véhicule ferroviaire 4. Pour ce faire, le support 20 est fixé sur le véhicule ferroviaire 4. Par exemple, le corps 30 du support 20 est fixé sur le véhicule ferroviaire 4, en particulier sur un absorbeur de choc 14 du véhicule ferroviaire 4.The tool 6 is first positioned on the railway vehicle 4. To do this, the support 20 is fixed on the railway vehicle 4. For example, the body 30 of the support 20 is fixed on the railway vehicle 4, in particular on a shock absorber 14 of the railway vehicle 4.

Le mécanisme d'actionnement 18 est disposé entre le support 20 et l'attelage 12. En particulier, la tige d'actionnement 22 est engagée dans l'ouverture 34 du bras 32, le premier organe de liaison 26 venant en appui contre le bras 32 du support 20, et le deuxième organe de liaison 28 étant attaché à l'attelage 12.The actuation mechanism 18 is arranged between the support 20 and the hitch 12. In particular, the actuation rod 22 is engaged in the opening 34 of the arm 32, the first connecting member 26 bearing against the arm 32 of the support 20, and the second connecting member 28 being attached to the hitch 12.

L'organe de manoeuvre 24 est tourné par l'opérateur dans le sens d'un rapprochement de l'attelage 12 du support 20, si besoin, par exemple au début de l'opération, en immobilisant manuellement en rotation le premier organe de liaison 26.The operating member 24 is turned by the operator in the direction of bringing the hitch 12 closer to the support 20, if necessary, for example at the start of the operation, by manually immobilizing the first connecting member in rotation 26.

Du fait de la rotation de la tige d'actionnement 22 autour de son axe d'extension A-A', le premier organe de liaison 26, qui est immobilisé en rotation, tend à se déplacer le long la tige d'actionnement 22 vers le deuxième organe de liaison 28.Due to the rotation of the actuating rod 22 around its axis of extension A-A', the first connecting member 26, which is immobilized in rotation, tends to move along the actuating rod 22 towards the second connecting member 28.

Dès lors que le premier organe de liaison 26 est en appui contre le support 20, la rotation de la tige d'actionnement 22 provoque un déplacement de la tige d'actionnement 22 par rapport au support 20 dans le sens d'un rapprochement du deuxième organe de liaison 28 et du premier organe de liaison 26, et donc d'un rapprochement de l'attelage 12 et du support 20.As soon as the first connecting member 26 bears against the support 20, the rotation of the actuating rod 22 causes a movement of the actuating rod 22 relative to the support 20 in the direction of an approach of the second connecting member 28 and the first connecting member 26, and therefore a rapprochement of the hitch 12 and the support 20.

L'effort nécessaire au déplacement latéral de l'attelage 12 est exercé par l'intermédiaire de la tige d'actionnement 22 en étant repris par le support 20 qui est fixé sur le châssis du véhicule 4.The force necessary for the lateral movement of the hitch 12 is exerted via the actuating rod 22 while being taken up by the support 20 which is fixed on the chassis of the vehicle 4.

Ainsi, l'effort exercé par l'opérateur pour faire tourner l'organe de manoeuvre 24 est converti en un effort de déplacement latéral de l'attelage 12 exercé entre l'attelage 12 et le support 20 qui est fixé sur le châssis du véhicule 4. L'opérateur n'exerce pas directement un effort de traction sur l'attelage 12.Thus, the effort exerted by the operator to rotate the operating member 24 is converted into a lateral movement force of the hitch 12 exerted between the hitch 12 and the support 20 which is fixed on the chassis of the vehicle 4. The operator does not directly exert a traction force on the hitch 12.

Par ailleurs, la liaison entre la tige d'actionnement 22 et chacun de l'attelage 12 et du support 20 permet de maintenir l'attelage 12 dans la position atteinte en l'absence d'effort appliqué sur l'organe de manoeuvre 24.Furthermore, the connection between the actuating rod 22 and each of the hitch 12 and the support 20 makes it possible to maintain the hitch 12 in the position reached in the absence of force applied to the operating member 24.

Lorsque le déplacement de l'attelage 12 n'est plus nécessaire, par exemple, l'opérateur retire le mécanisme d'actionnement 18 en détachant le premier organe de liaison 26 du support 20 et le deuxième organe de liaison 28 de l'attelage 12, et sépare le support 20 du véhicule ferroviaire 4.When moving the hitch 12 is no longer necessary, for example, the operator removes the actuating mechanism 18 by detaching the first connecting member 26 from the support 20 and the second connecting member 28 from the hitch 12 , and separates the support 20 from the railway vehicle 4.

L'outil 6 peut alors être rangé en vue d'une éventuelle nouvelle future utilisation.Tool 6 can then be stored for possible new future use.

L'invention facilite le déplacement manuel de l'attelage 12. Il permet d'appliquer sur l'attelage une force de traction conséquente tout en ne requérant d'un utilisateur qu'une application d'un effort modéré sur l'organe de manoeuvre 24.The invention facilitates the manual movement of the hitch 12. It makes it possible to apply a substantial traction force to the hitch while only requiring a user to apply a moderate effort to the operating member. 24.

En outre, l'invention permet à l'utilisateur de déplacer l'attelage 12 en lui évitant de descendre sur la voie. Ceci améliore donc la sécurité de l'utilisateur lors du déplacement de l'attelage 12.Furthermore, the invention allows the user to move the hitch 12 without having to go down the track. This therefore improves the safety of the user when moving the hitch 12.

L'invention n'est pas limitée aux exemples de réalisation décrits ci-dessus, d'autres exemples de réalisation étant envisageables.The invention is not limited to the exemplary embodiments described above, other exemplary embodiments being possible.

Ainsi, dans un exemple de réalisation, le deuxième organe de liaison 28 est mobile le long de la tige d'actionnement 22.Thus, in an exemplary embodiment, the second connecting member 28 is movable along the actuating rod 22.

Dans ce cas, le deuxième organe de liaison 28 est par exemple vissé sur une portion filetée de la tige d'actionnement 22. Dans un tel cas, le premier organe de liaison 26 est immobile le long du tirant ou mobile le long de la tige d'actionnement 22 comme prévu précédemment.In this case, the second connecting member 28 is for example screwed onto a threaded portion of the actuating rod 22. In such a case, the first connecting member 26 is stationary along the tie rod or movable along the rod actuation 22 as previously planned.

Dans l'exemple illustré, le premier organe de liaison 26 permet de lier la tige d'actionnement 22 au support 20 de manière amovible. Ceci facilite le transport de l'outil 6 et/ou l'installation de l'outil 6 sur le véhicule ferroviaire 4. En variante, le deuxième organe de liaison 26 est monté à demeure sur le support 20.In the example illustrated, the first connecting member 26 makes it possible to connect the actuating rod 22 to the support 20 in a removable manner. This facilitates the transport of the tool 6 and/or the installation of the tool 6 on the railway vehicle 4. Alternatively, the second connecting member 26 is permanently mounted on the support 20.
