Description

La présente invention se rapporte à un dispositif de guidage en translation d'un dispositif mobile de manutention du genre pont roulant, destiné en particulier à assurer un guidage défini d'un pont roulant, pont transbordeur, ou analogue, dont les chemins de roulement ancrés au sol ont été par la suite déformés dans le plan horizontal et ne sont plus réglables.The present invention relates to a device for guiding in translation a mobile handling device of the overhead crane type, intended in particular to provide defined guidance for an overhead crane, transporter bridge, or the like, whose anchored raceways on the ground were subsequently deformed in the horizontal plane and are no longer adjustable.

D'une manière générale, un pont roulant est constitué d'une structure rigide composée d'une ou deux poutres maîtresses transversales reposant par leurs extrémités sur deux sommiers longitudinaux. Cette structure est portée par deux paires de galets porteurs, une de chaque côté du pont, roulant sur deux rails eux-mêmes fixés sur deux profilés, dits "chemins de roulement", ancrés dans le sol ou dans un bâti support de l'ensemble de l'installation. Le pont est guidé en translation par l'intermédiaire d'au moins deux paires de galets de guidage d'axes verticaux, fixés sur au moins un des deux sommiers et roulant sur les faces latérales d'au moins un des deux rails de roulement du pont.In general, an overhead crane consists of a rigid structure composed of one or two transverse main beams resting at their ends on two longitudinal beams. This structure is carried by two pairs of support rollers, one on each side of the bridge, rolling on two rails themselves fixed on two profiles, called "raceways", anchored in the ground or in a frame supporting the assembly of the installation. The bridge is guided in translation by means of at least two pairs of guide rollers with vertical axes, fixed on at least one of the two bed bases and rolling on the lateral faces of at least one of the two running rails of the bridge.

Il arrive quelquefois que le sol dans lequel sont ancrés les profilés dits "chemins de roulement" vienne à se déformer par la suite.It sometimes happens that the soil in which the so-called "raceways" profiles are anchored becomes deformed thereafter.

Dans le cas par exemple d'un pont roulant évoluant au-dessus d'une piscine de stockage de combustible nucléaire, il arrive très fréquem- ment que les murs latéraux, et donc les supports de rails, subissent, après remplissage en eau de la piscine, une déformation assez importante pouvant aller jusqu'à plusieurs centimètres dans le sens transversal. Par suite les rails de roulement, qui pour la bonne transmission des efforts doivent être obligatoirement centrés sur l'âme de leur profilé de support, ne peuvent assurer leur fonction de guidage du pont avec une précision suffisante.In the case, for example, of an overhead crane operating above a nuclear fuel storage pool, it very often happens that the side walls, and therefore the rail supports, undergo, after filling with water, swimming pool, a fairly significant deformation of up to several centimeters in the transverse direction. As a result the running rails, which for the correct transmission of forces must be centered on the core of their support profile, can not ensure their guiding function of the bridge with sufficient precision.

De manière classique on compense ces déformations en reliant les ensembles de galets de guidage associés de part et d'autre du pont par un dispositif comportant des tringles transversales assurant des mouvements de ces blocs de guidage symétriques par rapport à l'axe longitudinal du pont roulant.Conventionally, these deformations are compensated for by connecting the sets of associated guide rollers on either side of the bridge by a device comprising transverse rods ensuring movements of these guide blocks symmetrical with respect to the longitudinal axis of the crane. .

De tels dispositifs sont complexes et de mise au point difficile, surtout dans le cas de ponts de grande largeur, tels que ceux évoluant au-dessus des piscines de stockage de combustible nucléaire.Such devices are complex and difficult to develop, especially in the case of large bridges, such as those operating above nuclear fuel storage pools.

Par ailleurs, les déformations des murs de la piscine n'étant pas symétriques, le pont tend à se déplacer perpendiculairement à la ligne moyenne de déformation des deux rails associés, de sorte qu'il ne se déplace pas parallèlement à lui-même.Furthermore, the deformations of the pool walls are not symmetrical, the bridge tends to move perpendicular to the mean line of deformation of the two associated rails, so that it does not move parallel to itself.

Le dispositif de guidage de pont roulant, pont transbordeur, ou analogue, conforme à l'invention ne présente pas ces inconvénients. Il est caractérisé en ce qu'au moins un profilé supplémentaire est placé entre au moins un des chemins de roulement ancrés au sol et le rail qu'il supporte, en ce que des galets de guidage sont placés de manière à rouler sur les deux faces latérales de ce profilé supplémentaire, en ce que ledit rail est fixé à son chemin de roulement par l'intermédiaire de moyens destinés à permettre un réglage latéral en position de ce profilé afin qu'il assure une ligne de guidage définie, et en ce que les galets porteurs du pont roulant sont suffisamment larges pour toujours reposer sur leurs rails lorsque le pont parcourt cette ligne. Par exemple, dans le cas précité d'un pont roulant pour piscine de stockage de combustible nucléaire, la ligne de guidage est avantageusement rectiligne.The overhead crane guide device, transporter bridge, or the like, according to the invention does not have these drawbacks. It is characterized in that at least one additional profile is placed between at least one of the raceways anchored to the ground and the rail which it supports, in that guide rollers are placed so as to roll on both sides lateral of this additional profile, in that said rail is fixed to its raceway by means intended to allow lateral adjustment in position of this profile so that it provides a defined guide line, and in that the bearing rollers of the crane are wide enough to always rest on their rails when the bridge crosses this line. For example, in the above-mentioned case of an overhead crane for a nuclear fuel storage pool, the guide line is advantageously rectilinear.

L'invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation, en référence aux dessins annexés dans lesquels :

  • - la figure 1 est une vue en bout d'un des côtés d'un pont roulant équipé du dispositif de guidage de l'invention, à un endroit où le chemin de roulement n'est pas déformé,
  • - la figure 2 est une vue en bout du même côté du pont roulant à un endroit où le chemin de roulement est déformé,
  • - la figure 3 est une vue en perspective du profilé supplémentaire de guidage de l'invention.
The invention will be better understood with the aid of the following description of an exemplary embodiment, with reference to the appended drawings in which:
  • FIG. 1 is an end view of one of the sides of an overhead crane equipped with the guiding device of the invention, at a place where the raceway is not deformed,
  • FIG. 2 is an end view of the same side of the overhead crane at a place where the raceway is deformed,
  • - Figure 3 is a perspective view of the additional guide profile of the invention.

On reconnatt sur la figure 1 une des poutres mattresses transversales 1 et un des sommiers 2 du pont roulant de l'invention. De manière classique, le sommier 2 porte deux galets porteurs 3 qui supportent le pont roulant en lui permettant de rouler sur deux rails 4. De manière classique également, chacun des deux rails 4 est posé et fixé par des boulons 5 sur un profilé 6 en I, appelé "chemin de roulement", lui-même scellé, comme représenté, dans le sol en béton formant les bords de la piscine de stockage de combustible nucléaire par exemple.One recognizes in FIG. 1 one of the transverse mattress beams 1 and one of the bed bases 2 of the overhead crane of the invention. Conventionally, the bed base 2 carries two support rollers 3 which support the overhead crane allowing it to roll on two rails 4. Also conventionally, each of the two rails 4 is placed and fixed by bolts 5 on a section 6 in I, called "raceway", itself sealed, as shown, in the concrete floor forming the edges of the nuclear fuel storage pool for example.

Conformément à l'invention, un profilé supplémentaire 8 en H est interposé entre le rail 4 et le chemin de roulement 6, et ses deux faces latérales servent de chemin de roulement pour deux couples de galets de guidage 9 classiques, à axes verticaux, fixés au sommier 2 du pont roulant.According to the invention, an additional section 8 in H is interposed between the rail 4 and the raceway 6, and its two lateral faces serve as the raceway for two pairs of conventional guide rollers 9, with vertical axes, fixed at the bed base 2 of the overhead crane.

Ce profile supplémentaire, représenté en perspective sur la tigu- re 3, est garni à intervalles réguliers de lumières transversales 10 à travers lesquelles passent les boulons de fixation 5 du rail 4 sur le chemin de roulement 6. Il est donc réglable en position latérale, de sorte qu'il est à même d'assurer, malgré les déformations transversales du sol 7, le guidage désiré du pont, par exemple un guidage rigoureusement rectiligne.This additional profile, shown in perspective on the rod 3, is furnished at regular intervals with transverse slots 10 through which the fixing bolts 5 of the rail 4 pass on the raceway 6. It is therefore adjustable in the lateral position, so that it is able to ensure, despite the transverse deformations of the ground 7, the desired guidance of the bridge, for example a strictly straight guide.

A l'endroit tel que représenté sur la figure 1, le sol 7 n'est pas déformé, de sorte que la position transversale du profilé de guidage 8 est réglée pour se trouver centrée sur l'axe de symétrie de l'ensemble constitué par le rail 8 et son chemin de roulement 6. Comme représenté par la flèche 11, la force d'appui du pont roulant s'exerce sur l'âme du rail 8 et de son chemin de roulement 6, de sorte que les efforts sont correctement transmis.At the place as shown in Figure 1, the ground 7 is not deformed, so that the transverse position of the guide profile 8 is adjusted to be centered on the axis of symmetry of the assembly formed by the rail 8 and its raceway 6. As shown by the arrow 11, the bearing force of the crane is exerted on the web of the rail 8 and of its raceway 6, so that the forces are correctly transmitted.

On a représenté sur la figure 2 le pont roulant passant à un endroit où le sol 7 en béton s'est trouvé décalé vers la droite de quelques centimètres après que l'on y ait scellé le chemin de roulement 6. A cet endroit, et conformément à l'invention, le profilé 8 de l'invention est réglé de manière à être décalé d'autant vers la gauche par rapport à sa position médiane de la figure 1, afin d'assurer avec les galets 9 un guidage rectiligne du pont roulant. Evidemment, comme représenté sur le dessin, il est nécessaire que le galet porteur 3 soit assez large pour toujours reposer sur le rail 8 à cet endroit. La force d'appui du pont roulant s'exerce toujours dans ce cas, comme représenté par la flèche 12, sur l'âme du rail 8 et de son chemin de roulement 6.FIG. 2 shows the overhead crane passing at a location where the concrete floor 7 has been shifted to the right by a few centimeters after the raceway 6 has been sealed there. At this location, and in accordance with the invention, the profile 8 of the invention is adjusted so as to be shifted correspondingly to the left relative to its median position in FIG. 1, in order to ensure with the rollers 9 a rectilinear guide of the bridge rolling. Obviously, as shown in the drawing, it is necessary that the carrier roller 3 is wide enough to always rest on the rail 8 at this location. The bearing force of the crane is always exerted in this case, as shown by the arrow 12, on the core of the rail 8 and of its raceway 6.

Dans l'exemple représenté, le côté représenté du pont roulant est muni de deux couples, décalés longitudinalement, de galets de guidage 9 roulant sur les deux faces latérales du profilé 8. Ce guidage d'un seul côté est suffisant, de sorte que l'autre côté du pont ne comporte pas les galets 9 ni le profilé 8. Ses deux galets porteurs ont néanmoins, comme les galets 3, une largeur suffisante pour rouler sur le deuxième rail déformé correspondant au côté où ils se trouvent.In the example shown, the side shown of the crane is provided with two pairs, longitudinally offset, of guide rollers 9 rolling on the two lateral faces of the profile 8. This guidance on one side is sufficient, so that the 'other side of the bridge does not have the rollers 9 or the profile 8. Its two supporting rollers, however, like the rollers 3, have a width sufficient to roll on the second deformed rail corresponding to the side where they are located.

En pratique, surtout dans le cas où le chemin de roulement du pont est assez long, on prévoit, conformément à l'invention, plusieurs profilés supplémentaires de guidage tels que le profilé 8, et on place ces profilés bout à bout. Il est ensuite assez aisé de les régler séparément en position transversale pour qu'ils définissent tous ensemble une certaine ligne de guidage, soit droite dans le cas général, soit avec une forme définie telle qu'une forme de S pour certaines applications particulières. A titre d'exemple de réalisation, un ensemble de dix profilés alignés, tels que le profilé 8 de chacun dix mètres de long et cinquante centimètres de large, conviennent très bien pour assurer le guidage rectiligne d'un pont roulant se déplaçant sur une piscine de stockage de combustible nucléaire de cent mètres de long et de vingt mètres de large.In practice, especially in the case where the raceway of the bridge is long enough, provision is made, in accordance with the invention, for several additional guide sections such as the section 8, and these sections are placed end to end. It is then quite easy to adjust them separately in transverse position so that they all define a certain guide line, either straight in the general case, or with a defined shape such as an S shape for certain particular applications. AT As an example of an embodiment, a set of ten aligned profiles, such as profile 8, each ten meters long and fifty centimeters wide, are very suitable for ensuring the rectilinear guidance of an overhead crane moving over a swimming pool of storage of nuclear fuel one hundred meters long and twenty meters wide.
