Description

p;Posltlf d'aPPui latéral PoYr trains de roulement à valets ; Dont roulant antisismiaue équipé de tels trains
La présente invention concerne un dispositif d'appui latéral pour trains de roulement à galets, du type comportant une poutre portant au moins un galet d'appui vertical & axe horizontal, propre à rouler sur un rail, et au moins deux galets d'appui latéral ê axes verticaux
De tels dispositifs d'appui latéral sont connus dans de très diverses applications, lorsqu'il s'agit de maintenir dans l'axe du rail le galet d'appui vertical, à l'encontre des sollicitations qui peuvent s'exercer latéralement sur la poutre.
p; lateral support position for valet undercarriages; Including anti-seismic rolling equipped with such trains
The present invention relates to a lateral support device for roller undercarriages, of the type comprising a beam carrying at least one vertical support roller & horizontal axis, suitable for rolling on a rail, and at least two support rollers lateral to vertical axes
Such lateral support devices are known in very various applications, when it is a question of holding the vertical support roller in the axis of the rail, against the stresses which can be exerted laterally on the beam.

Le problème peut se poser en particulier dans les ponts roulants antisismiques du type en console, mobiles en translation, ces ponts pouvant être destinés par exemple à trans-porter des conteneurs blindés contenant du combustible irradié. Ce type de pont en console roule sur deux rails, sur l'un par l'intermédiaire d'un train de deux galets motorisés et pouvant être freinés, sur l'autre par l'intermédiaire d'un seul galet, lequel, en raison de la charge plus faible en cette extrémité du pont, ou pour une question d'économie, n'est en principe pas motorisé. Ces ponts ont ainsi, vus en plan, une forme générale triangulaire, ce qui présente l'avantage important de diminuer leur encombrement. The problem can arise in particular in anti-seismic overhead traveling cranes of the console type, mobile in translation, these bridges can be intended for example to transport armored containers containing irradiated fuel. This type of console bridge runs on two rails, on one via a train of two motorized rollers which can be braked, on the other via a single roller, which, due the lower load at this end of the bridge, or for reasons of economy, is in principle not motorized. These bridges thus have, seen in plan, a generally triangular shape, which has the important advantage of reducing their bulk.

De tels ponts roulants en console sont cependant très sensibles aux vibrations sismiques horizontales en
X et Y, & savoir à celles qui s'exercent essentiellement dans la direction des rails et accessoirement à celles qui s'exercent dans la direction perpendiculaire à la présente.
However, such console overhead cranes are very sensitive to horizontal seismic vibrations in
X and Y, & namely to those which are exerted essentially in the direction of the rails and incidentally to those which are exerted in the direction perpendicular to the present.

Dans la direction des rails, notamment, tout se passe comme-si les galets motorisés, à une extrémité du pont, étaient bloqués, alors qu'à l'autre extrémité, à la pointe du triangle le galet reste. libre de se déplacer dans la direction du rail. Le pont roulant se comporte alors, vis- & vis de ce type de vibrations sismiques, comme une poutre à extrémité vibrante, très fortement sollicitée au niveau de son encastrement, ce qui, lors de séismes d'amplitude importante, risque de créer une rupture des galets de guidage, et une chute du pont. In the direction of the rails, in particular, everything happens as if the motorized rollers, at one end of the bridge, were blocked, while at the other end, at the tip of the triangle, the roller remains. free to move in the direction of the rail. The overhead crane then behaves, with respect to this type of seismic vibration, like a beam with a vibrating end, very strongly stressed at the level of its embedding, which, during earthquakes of large amplitude, risks creating a rupture. guide rollers, and a fall from the bridge.

I1 convenait donc de prévoir, au niveau des deux galets moteurs, un dispositif d'appui, rappelant élastiquement ces galets dans l'axe du rail, par l'intermédiaire de deux galets d'appui latéral. It was therefore appropriate to provide, at the level of the two drive rollers, a support device, elastically recalling these rollers in the axis of the rail, by means of two lateral support rollers.

Le but de la présente invention est d'obtenir un tel dispositif d'appui qui soit simple, peu encombrant, bon marché, fiable et non soumis à une fatigue permanente, toutes qualités que ne présentent pas les dispositifs connus à systèmes amortisseurs hydrauliques ou en néoprène, qui sont en outre délicats à mettre en oeuvre, avec d'importantes contraintes d'entretien et de surveillance. The object of the present invention is to obtain such a support device which is simple, compact, inexpensive, reliable and not subject to permanent fatigue, all qualities that do not have known devices with hydraulic shock-absorbing systems or in neoprene, which are also delicate to implement, with significant maintenance and monitoring constraints.

Pour ce faire, un dispositif d'appui latéral du type défini au début est, conformément à la présente invention, essentiellement caractérisé en ce qu'il comporte au moins une barre de torsion pour solliciter lesdits galets d'appui latéral à prendre appui élastiquement de part et d'autre du rail. To do this, a lateral support device of the type defined at the start is, in accordance with the present invention, essentially characterized in that it comprises at least one torsion bar for urging said lateral support rollers to be elastically supported by on either side of the rail.

On obtient ainsi un rappel élastique bilatéral qui, outre les qualités requises énoncées plus haut, présente l'avantage de ne nécessiter ni entretien ni surveillance, et d'être parfaitement réversible, au point de vue de son comportement vis-à-vis des efforts. A bilateral elastic return is thus obtained which, in addition to the requisite qualities set out above, has the advantage of requiring no maintenance or supervision, and of being perfectly reversible, from the point of view of its behavior with respect to forces. .

Quant à sa réalisation, c'est-à-dire à la liaison mécanique entre la barre de torsion et les galets d'appui latéral, elle peut avantageusement se caractériser en ce que les axes desdits galets d'appui latéral sont portés par les extrémités d'un palonnier dont le point milieu est articulé à l'extrémité d'une chape, l'autre extrémité de cette chape étant calée sur la barre de torsion. As for its embodiment, that is to say the mechanical connection between the torsion bar and the side support rollers, it can advantageously be characterized in that the axes of said side support rollers are carried by the ends a lifting beam whose midpoint is articulated at the end of a yoke, the other end of this yoke being wedged on the torsion bar.

D'autres détails de réalisation seront vus maintenant à la lecture de l'exemple décrit ci-dessous avec référence aux figures du dessin annexé dans lequel
- la figure 1 est une vue de détail, en perspective, avec arrachement partiel, d'un dispositif d'appui latéral conforme à l'invention ; et
- la figure 2 est une vue d'ensemble schématique, en perspective, montrant un pont roulant du type en console, équipé de tels dispositifs.
Other details of embodiment will now be seen on reading the example described below with reference to the figures of the appended drawing in which
- Figure 1 is a detail view, in perspective, partially broken away, of a lateral support device according to the invention; and
- Figure 2 is a schematic overview, in perspective, showing an overhead crane of the console type, equipped with such devices.

Sur la figure 1 on a référencé en 1 la poutre portant un galet d'appui vertical 2, à axe horizontal 3, apte à rouler sur un rail 4. Les galets d'appui latéral ont été référencés 5 et sont à axes 6 verticaux, ces axes étant contenus dans un plan perpendiculaire au rail 4. Ces axes 6 sont portés par les extrémités d'un palon nier 7 dont le point milieu 8 est articulé & à extrémité d'une chape verticale 9. L'autre- extrémité de cette chape est calée sur une barre de torsion 10 qui est montée entre un encastrement il et un palier 12 solidaires de la poutre 1. Enfin, ledit palonnier 7 est maiptenu å ses extrémités par deux guides 13 en U solidaires de la poutre I et propres à n'autoriser ses déplacements que dans la direction perpendiculaire audit rail 4. In FIG. 1, the beam carrying a vertical support roller 2, with a horizontal axis 3, able to roll on a rail has been referenced in 1. The lateral support rollers have been referenced 5 and are with vertical axes 6, these axes being contained in a plane perpendicular to the rail 4. These axes 6 are carried by the ends of a nier block 7 whose mid point 8 is articulated & at the end of a vertical yoke 9. The other end of this yoke is wedged on a torsion bar 10 which is mounted between a recess il and a bearing 12 secured to the beam 1. Finally, said spreader 7 is maiptenu at its ends by two guides 13 in U secured to the beam I and suitable for authorize its movements only in the direction perpendicular to said rail 4.

Ceci étant, on voit que tout effort latéral s exerçant dans un sens ou dans l'autre sur ce train de roulement (flèches f) se traduira par une sollicitation de la barre de torsion 10, par l'intermédiaire des galets 5, du palonnier 7 et de la chape 9, tendant à ramener à chaque fois le galet d'appui vertical 2 dans l'axe de la poutre 1.  This being the case, it can be seen that any lateral force exerted in one direction or the other on this undercarriage (arrows f) will result in stress on the torsion bar 10, via the rollers 5, of the lifter 7 and the yoke 9, tending to bring each time the vertical support roller 2 in the axis of the beam 1.

On peut faire en sorte que la chape 9 puisse ne pivoter qu'en cas de dépassement d'un effort minimum, par exemple grâce à une goupille d'arrêt cassant sous une charge prédéterminée.  We can make sure that the yoke 9 can only pivot in the event that a minimum effort is exceeded, for example by means of a locking pin breaking under a predetermined load.

Sur la figure 2, on a utilisé les mêmes références pour désigner les mêmes organes que sur la figure 1. In FIG. 2, the same references have been used to designate the same members as in FIG. 1.

On voit que le pont roulant a une forme générale pratiquement triangulaire, et est constitué d'un assemblage de poutres 1, 14 et 15 dont l'extrémité pointue est portée par un rail 16, par l'intermédiaire d'un galet de roulement 17. Le rail 4 porte deux galets verticaux 2, ayant chacun son dispositif à galets d'appui latéral 5, chape 9 et barre de torsion 10, organes qui permettent à la poutre 1 de rester dans l'axe du rail 4, nonobstant les efforts transversaux f qui seraient dus à la conjugaison des vibrations sismiques horizontales dans une direction X parallèle aux rails, et de la forme en console du pont roulant.  We see that the traveling crane has a generally triangular general shape, and consists of an assembly of beams 1, 14 and 15, the pointed end of which is carried by a rail 16, by means of a rolling roller 17 The rail 4 carries two vertical rollers 2, each having its device with lateral support rollers 5, yoke 9 and torsion bar 10, members which allow the beam 1 to remain in the axis of the rail 4, notwithstanding the efforts transverse f which would be due to the combination of horizontal seismic vibrations in a direction X parallel to the rails, and the console shape of the crane.
