Abstract

1. A railway unit for handling and placing cumbersome loads, characterized in that it is made of at least two wagons (1, 2) carrying each a crane (5), whereby said wagons can be coupled to each other by means of a standard coupler (6) disposed between their buffers, and in that the platforms (3) of said wagons carry at least a telescopic stretcher provided at one of its ends with a coupling device (10) adapted for working in traction as well as in thrust.

Description

L'invention concerne un ensemble ferroviaire pour la manutention et la pose de charges encombrantes et plus particulièrement les wagons-grues pour la pose des aiguillages. Les wagons-grues actuellement connus sont constitués d'une plate-forme, généralement automotrice, portant deux grues montées sur tourelle disposées chacune sensiblement au niveau de chacun des essieux ou bogies de la plate-forme.The invention relates to a railway assembly for handling and placing bulky loads and more particularly crane wagons for laying switches. The currently known crane wagons consist of a platform, generally self-propelled, carrying two cranes mounted on a turret each disposed substantially at the level of each of the axles or bogies of the platform.

Ces wagons-grues ne peuvent être utilisés que pour des aiguillages ou charges d'une longueur maximale de l'ordre d'une vingtaine de mètres, alors qu'il est fréquent d'avoir à poser des aiguillages ou charges d'une longueur supérieure à quarante mètres.These crane wagons can only be used for switches or loads of a maximum length of around twenty meters, while it is common to have to put switches or loads of greater length at forty meters.

Cette limitation dans la capacité d'utilisation des wagons-grues est essentiellement due à l'impossibilité d'augmenter dans les proportions voulues l'écartement entre les flèches des deux grues.This limitation in the capacity of use of the crane wagons is essentially due to the impossibility of increasing in the desired proportions the spacing between the jibs of the two cranes.

L'invention a pour but de remédier à cet inconvénient et de procurer un ensemble ferroviaire pour la manutention et la pose de charges encombrantes, dans lequel il est possible de faire varier l'écartement entre les flèches des grues en fonction de la longueur de la charge à manutentionner.The object of the invention is to remedy this drawback and to provide a railway assembly for handling and placing bulky loads, in which it is possible to vary the spacing between the crane jibs as a function of the length of the load to be handled.

A cet effet, l'ensemble ferroviaire selon l'invention est caractérisé en ce qu'il est constitué par deux wagons dont chacun porte une grue et pouvant être attelés ensemble au moyen d'un attelage classique, et en ce que les plate-formes desdits wagons portent au moins un extenseur télescopique muni, à l'une de ses extrémités, d'un dispositif d'attelage capable de travailler aussi bien en traction qu'en poussée.To this end, the railway assembly according to the invention is characterized in that it is constituted by two wagons each of which carries a crane and which can be coupled together by means of a conventional coupling, and in that the platforms said wagons carry at least one telescopic expander provided, at one of its ends, with a coupling device capable of working both in traction and in pushing.

Selon d'autres caractéristiques importantes de la présente invention :

  • - chaque plate-forme porte un extenseur télescopique muni d'un dispositif d'attelage automatique,
  • - l'extenseur est constitué par une barre d'attelage coulissant dans un fourreau ou manchon fixé sur la plate-forme et portant une succession de trous de réglage destinés à recevoir une broche.
According to other important features of the present invention:
  • - each platform carries a telescopic expander fitted with an automatic coupling device,
  • - The expander is constituted by a drawbar sliding in a sheath or sleeve fixed on the platform and carrying a succession of adjustment holes intended to receive a spindle.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'un exemple non limitatif de réalisation d'un ensemble ferroviaire conforme à l'invention.Other characteristics and advantages of the invention will emerge from the description which follows of a nonlimiting example of embodiment of a railway assembly according to the invention.

Pour mieux comprendre la description, on se référera au dessin annexé, dans lequel :

  • La figure 1 est une vue schématique d'un ensemble ferroviaire conforme à l'invention, les deux wagons étant attelés ;
  • La figure 2 est une vue schématique de l'ensemble de la figure 1, les grues étant omises, les deux wagons étant écartés l'un de l'autre au moyen de l'extenseur télescopique.
  • La figure 3 est une vue schématique d'un ensemble selon la figure 2, avec interposition entre les deux wagons porteurs de grues d'une plate-forme prolongatrice.
To better understand the description, reference is made to the appended drawing, in which:
  • Figure 1 is a schematic view of a rail assembly according to the invention, the two cars being coupled;
  • Figure 2 is a schematic view of the assembly of Figure 1, the cranes being omitted, the two wagons being spaced from each other by means of the telescopic expander.
  • Figure 3 is a schematic view of an assembly according to Figure 2, with interposition between the two crane wagons of an extension platform.

L'ensemble ferroviaire selon l'invention comporte deux wagons 1 et 2 constitués chacun d'une plate-forme 3, supportée par deux bogies 4. Chaque plate-forme porte en son milieu une grue 5, montée sur une tourelle, analogue aux grues des wagons-grues actuellement connus.The railway assembly according to the invention comprises two wagons 1 and 2 each consisting of a platform 3, supported by two bogies 4. Each platform carries in its center a crane 5, mounted on a turret, similar to cranes currently known crane wagons.

Les deux wagons peuvent être attelés entre eux au moyen des attelages classiques 6 disposés entre leurs tampons.The two wagons can be coupled to each other by means of conventional couplings 6 arranged between their buffers.

Comme on le voit sur la figure 1, sur chaque plate-forme 3 est fixé un extenseur 7, constitué par un fourreau ou manchon 8, à l'intérieur duquel une barre 9 est montée coulissante. L'extenseur 7 est disposé dans le sens longitudinal de la plate-forme 3, de telle sorte que, en position rétractée, l'extrémité de la barre 9 ne dépasse pas le bord de ladite plate-forme. A son extrémité libre, la barre 9 porte des moyens d'accrochage 10, destinés à coopérer avec des moyens d'accrochage correspondants, fixés sur la plate-forme du second wagon, ou, comme dans l'exemple représenté, à l'extrémité libre de la barre 9 de l'extenseur fixé sur ladite plate-forme.As seen in Figure 1, on each platform 3 is fixed a stent 7, consisting of a sleeve or sleeve 8, inside which a bar 9 is slidably mounted. The expander 7 is arranged in the longitudinal direction of the platform 3, so that, in the retracted position, the end of the bar 9 does not exceed the edge of said platform. At its free end, the bar 9 carries hooking means 10, intended to cooperate with corresponding hooking means, fixed on the platform of the second wagon, or, as in the example shown, at the end free from the bar 9 of the expander fixed on said platform.

De préférence, les moyens d'accrochage 10 sont constitués par un attelage automatique pouvant travailler aussi bien en traction qu'en poussée, de type connu en soi, afin de permettre un déplacement d'ensemble dans les deux sens le long des voies, sans risquer de diminuer l'écartement des flèches ou de dételer les barres 9.Preferably, the hooking means 10 are constituted by an automatic coupling which can work both in traction and in thrust, of a type known per se, in order to allow an overall movement in both directions along the tracks, without risk reducing the spacing of the arrows or uncoupling the bars 9.

Chaque barre 9 comporte, sur toute sa longueur, une succession de trous non représentés, destinés à recevoir une broche de blocage. On peut ainsi fixer la barre 9 dans la position correspondant à l'écartement désiré des flèches des grues.Each bar 9 has, over its entire length, a succession of holes not shown, intended to receive a locking pin. It is thus possible to fix the bar 9 in the position corresponding to the desired spacing of the crane jibs.

De préférence, l'un des deux wagons est automoteur.Preferably, one of the two wagons is self-propelled.

Comme on le voit sur la figure 2, lorsque l'on veut obtenir un écartement des flèches des grues supérieur à celui qu'elles présentent lorsque les deux wagons sont attelés l'un à l'autre, on dételle lesdits wagons, l'on solidarise les deux parties de l'attelage automatique fixées respectivement à l'extrémité libre de chacune des barres 9 et l'on éloigne les deux wagons l'un de l'autre de la distance désirée. On fixe l'écartement obtenu en introduisant une broche dans le trou approprié de chacune des barres.As can be seen in FIG. 2, when it is desired to obtain a spacing of the crane jibs greater than that which they present when the two wagons are coupled to one another, the said wagons are uncoupled, secures the two parts of the automatic coupling fixed respectively to the free end of each of the bars 9 and the two wagons are moved away from each other by the desired distance. The distance obtained is fixed by inserting a pin into the appropriate hole in each of the bars.

Lorsque l'on a atteint l'extension maximale de chacune des barres, il est encore possible, comme on le voit sur la figure 3, d'augmenter encore l'écartement des flèches en interposant entre les deux wagons un wagon supplémentaire 11, dépourvu de grue, dont la plate-forme porte à ses extrémités des dispositifs d'accrochage 10 destinés à coopérer avec ceux qui sont fixés aux extrémités des barres 9.When the maximum extension of each of the bars has been reached, it is still possible, as can be seen in FIG. 3, to further increase the spacing of the arrows by interposing between the two wagons an additional wagon 11, devoid of crane, the platform of which carries at its ends hooking devices 10 intended to cooperate with those which are fixed to the ends of the bars 9.

Bien que cela ne soit pas représenté sur les dessins, la plate-forme du wagon 11 peut être elle-même équipée d'extenseurs 7, destinés à coopérer avec les extenseurs de wagons porteurs de grue.Although this is not shown in the drawings, the platform of wagon 11 can itself be equipped with extenders 7, intended for cooperate with the expanders of crane-carrying wagons.

On peut également, à l'aide des éléments ci- dessus, constituer des ensembles ferroviaires pour la manutention de charges de très grande longueur, en utilisant plus de deux wagons porteurs de grues avec ou sans wagons prolongeurs intercalés.It is also possible, using the above elements, to form railway assemblies for handling very long loads, using more than two crane wagons with or without interposed extension wagons.

A titre indicatif, avec un ensemble constitué par trois wagons-grues et deux wagons prolongeurs intercalés, on peut manipuler des charges d'une longueur d'environ soixante mètres.As an indication, with a set consisting of three crane wagons and two interposed extension wagons, we can handle loads with a length of about sixty meters.

Selon une variante de réalisation non représentée, on peut utiliser comme extenseur un ou plusieurs vérins hydrauliques au lieu des barres décrites.According to an alternative embodiment not shown, one or more hydraulic cylinders can be used as the expander instead of the bars described.
