Abstract

The hydraulic actuator (2) is fixed to the frame of a lifting machine by a cradle (3). The cradle is welded to the front end (21) of the actuator cylinder (20) on the extraction side of the actuator rod (22). The cradle is welded by its base onto a plate (4) extending, parallel to the actuator axis, beyond the actuator front end and held in a casing (5) fixed to the frame. The plate has partial longitudinal cut outs dividing it into several parts (43). The casing has longitudinal compartments each of which contains one of these parts. The actuator fixing provides a third support point preventing transverse displacement of the actuator cylinder front end, thereby halving the buckling length.

Description

La présente invention a pour objet un dispositif de solidarisation d'un vérin hydraulique sur le bâti d'un engin de levage ou analogue. The present invention relates to a device for securing a hydraulic cylinder to the frame of a lifting machine or the like.

Un vérin hydraulique est généralement solidarisé uniquement par son extrémité arrière, opposée à celle d'où sort la tige, afin d'offrir un meilleur appui. A hydraulic cylinder is generally secured only by its rear end, opposite to that from which the rod comes out, in order to provide better support.

Cette solidarisation en un point unique, présente toutefois un inconvénient pour des vérins hydrauliques dont les tiges sont de grande longueur, on est effet confronté à un problème de flambage du fait de l'éloignement des deux points d'appui, ce qui risque de tordre ladite tige. This attachment at a single point, however has a drawback for hydraulic cylinders whose rods are very long, we are indeed faced with a problem of buckling due to the distance of the two support points, which may bend said rod.

Pour pallier cet inconvénient, on est obligé de surdimensionner le diamètre du vérin, notamment sa tige, avec pour inconvénients une augmentation importante de l'encombrement, des volumes, du poids et du prix du vérin, et une baisse de ses performances, notamment sa vitesse. To overcome this drawback, it is necessary to oversize the diameter of the jack, in particular its rod, with the drawbacks of a significant increase in the size, volumes, weight and price of the jack, and a drop in its performance, in particular its speed.

La présente invention a pour but de proposer un dispositif de solidarisation d'un vérin hydraulique sur le bâti d'un engin de levage ou analogue permettant de remédier à ces divers inconvénients. The present invention aims to provide a device for securing a hydraulic cylinder on the frame of a lifting device or the like to overcome these various drawbacks.

Le dispositif de solidarisation d'un vérin hydraulique sur le bâti d'un engin de levage ou analogue, alors que ledit vérin est solidarisé par son extrémité arrière audit bâti, se caractérise essentiellement en ce qu'il comporte un berceau, soudé à l'extrémité avant du cylindre dudit vérin, du côté d'extraction de la tige de ce dernier, ledit berceau étant soudé par sa base sur une platine s'étendant, parallèlement à l'axe dudit vérin, audelà de l'extrémité avant de celui-ci, et destinée à être introduite et maintenue dans un boîtier solidarisé audit bâti. The device for securing a hydraulic cylinder to the frame of a lifting machine or the like, while said cylinder is secured by its rear end to said frame, is essentially characterized in that it comprises a cradle, welded to the front end of the cylinder of said cylinder, on the extraction side of the rod of the latter, said cradle being welded by its base on a plate extending, parallel to the axis of said cylinder, beyond the front end of it ci, and intended to be introduced and maintained in a housing secured to said frame.

Selon une caractéristique additionnelle du dispositif selon l'invention la platine comporte des découpes longitudinales partielles la divisant en plusieurs parties, tandis que le boîtier comporte des compartiments longitudinaux destinés chacun à contenir l'une desdites parties. According to an additional characteristic of the device according to the invention, the plate comprises partial longitudinal cutouts dividing it into several parts, while the housing comprises longitudinal compartments each intended to contain one of said parts.

Le dispositif objet de la présente invention permet de créer un troisième point d'appui empêchant un déplacement transversal de l'extrémité avant du cylindre, et divisant ainsi par deux la longueur de flambage. The device which is the subject of the present invention makes it possible to create a third fulcrum preventing transverse displacement of the front end of the cylinder, and thus dividing the buckling length by two.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.

Dans le dessin annexé
- la figure 1 représente une vue en perspective et en éclaté d'un dispositif de solidarisation d'un vérin hydraulique selon l'invention.
In the attached drawing
- Figure 1 shows a perspective and exploded view of a device for securing a hydraulic cylinder according to the invention.

- la figure 2 représente une vue de profil d'un vérin équipé du même dispositif. - Figure 2 shows a side view of a jack fitted with the same device.

- la figure 3 représente une vue de dessus du même vérin. - Figure 3 shows a top view of the same cylinder.

Si on se réfère à la figure 1, on peut voir une dispositif 1 de solidarisation d'un vérin 2 sur le bâti d'un engin de levage ou analogue, non représenté. Referring to Figure 1, we can see a device 1 for securing a cylinder 2 on the frame of a lifting device or the like, not shown.

Le dispositif 1 comporte un berceau 3, soudé sur une platine 4, à une extrémité 40 de celle-ci, tandis que dans 1 l'autre extrémité 41 sont pratiquées deux découpes longitudinales partielles 42, qui séparent cette extrémité 41 en plusieurs parties 43 de manière à créer une sorte de fourche. The device 1 comprises a cradle 3, welded to a plate 4, at one end 40 of the latter, while in 1 the other end 41 are made two partial longitudinal cuts 42, which separate this end 41 into several parts 43 of so as to create a kind of fork.

Si on se réfère maintenant aux figures 2 et 3 on peut voir que le berceau 3 est solidarisé par soudage sur le cylindre 20 du vérin 2, à l'extrémité avant 21 de celui-ci du côté d'extraction de la tige 22 du vérin 2, de manière que les parties 43 de la platine 4 débordent le bord extrême du cylindre 20. If we now refer to Figures 2 and 3 we can see that the cradle 3 is secured by welding on the cylinder 20 of the cylinder 2, at the front end 21 thereof on the extraction side of the rod 22 of the cylinder 2, so that the parts 43 of the plate 4 extend beyond the end edge of the cylinder 20.

Sur ces figures, on peut également voir un boîtier 5, destiné à être solidarisé par des moyens appropriés au bâti, non représenté.  In these figures, one can also see a box 5, intended to be secured by means suitable for the frame, not shown.

Le boîtier 5 comporte une paroi supérieure 50, des parois latérales 51 et des parois internes 52, ces dernières délimitant des compartiments 53 dans chacun desquels peut être introduite l'une des parties 43 de la platine 4. The housing 5 has an upper wall 50, side walls 51 and internal walls 52, the latter defining compartments 53 into each of which can be inserted one of the parts 43 of the plate 4.

L'introduction des parties 43 de la platine 4 dans le boîtier 5 permet de solidariser la partie avant 21 du vérin 2 au bâti, tandis que la partie arrière 23 du vérin 2 lui est solidarisée de manière traditionnelle au moyen d'un anneau 24. The introduction of the parts 43 of the plate 4 into the housing 5 makes it possible to secure the front part 21 of the jack 2 to the frame, while the rear part 23 of the jack 2 is fixed to it in the traditional way by means of a ring 24.

I1 va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention.  It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.
