The invention concerns a turning device 5 for boiler construction, in order to facilitate the closing together of two hoops 1 and 2, for example before assembling them by welding. At least one of the rollers 6 is carried by the cheek plates 9 of a clevis 10 oscillating about a fixed pin 11, under the action of a jack 13. The latter can be controlled from a hand pump 14. Application: possibility for just one operator to perform the closing-together operations with precision and without external lifting means.

Description

La présenté invention est relative à une traverse de réglage du genre de celles qu'on utilise pour constituer un vireur de chaudronnerie. The present invention relates to an adjustment cross member of the type used to constitute a tacker for boilermaking.

On sait qu'un vireur de chaudronnerie est un mécanisme utilisé pour faire tourner autour de son axe géométrique ( généralement horizontal) , une virole de chaudronnerie qui est une pièce tubulaire en tôle dont le poids est couramment de plusieurs tonnes Q Il est nécessaire de faire virer la virole notamment pour l'assembler , ou pour la souder bord à bord avec une autre virole disposée dans son prolongement , autour du même axe géométrique
Traditionnellement , chaque vireur est formé de deux traverses portant chacune une paire de galets si bien que chaque virole repose à l'avant sur la paire de galets de la première traverse , et à l'arrière , sur la paire de galets de la seconde traverse.On comprend qu'un problème se pose lorsqu'vil s'agit d'accoster deux viroles , ct est-à-dire de les présenter exactement bord à bord , avant de les faire virer pour les assembler par soudage. Ce régla-e ge d'accostage est une opération de réglage fin qui doit être effectuée sur des viroles pesant couramment plusieurs tonnes.We know that a boilermaking tacker is a mechanism used to rotate around its geometric axis (generally horizontal), a boilermaking ferrule which is a tubular piece of sheet metal whose weight is commonly several tonnes Q It is necessary to make turn the ferrule in particular to assemble it, or to weld it edge to edge with another ferrule arranged in its extension, around the same geometric axis
Traditionally, each turner is formed of two crosspieces each carrying a pair of rollers so that each ferrule rests at the front on the pair of rollers of the first crosspiece, and at the rear on the pair of rollers of the second crosspiece . We understand that a problem arises when it comes to docking two ferrules, that is to say to present them exactly edge to edge, before turning them to assemble them by welding. This docking adjustment is a fine adjustment operation which must be carried out on ferrules commonly weighing several tonnes.

Habituellement , on suspend pour cela au moins l'une des viroles à un pont-roulant qui la soulève ou l'abaisse par approximations successives , jusqu a obtenir un positionnement à peu près satisfaisant.Usually, for this purpose at least one of the ferrules is suspended from an overhead crane which raises or lowers it by successive approximations, until an almost satisfactory positioning is obtained.

On comprend que cette opération soit longue et délicate , pour un résultat souvent médiocre.Enfin cette opération met en jeu des efforts importants , et elle ne peut pas être effectuée par un opérateur seul. We understand that this operation is long and delicate, for an often mediocre result. Finally, this operation involves significant efforts, and it cannot be carried out by an operator alone.

La présente invention a pour but d'éviter ces inconvénients , en réalisant une traverse de vireur qui permette à un homme seul d'effectuer avec précision , et sans fournir d'efforts importants , le réglage fin d'accostage de deux viroles. The object of the present invention is to avoid these drawbacks, by making a tacking cross-member which allows a single man to carry out precisely, and without providing significant effort, the fine adjustment of docking of two ferrules.

Une traverse de vireur selon l'invention comporte deux galets tournant chacun autour d'un axe supporté par une chape , et il est caractérisé en ce que l'une au moins des deux chapes a sa base articulée autour d'un axe fixe de la traverse , tandis qu'elle est pourvue d'un bras latéral ri gidement solidaire des flasques , et dont l'extrémité prend appui sur un vérin soutenu par ailleurs par la traverse fixe, des moyens étant prévus pour commander l'allongement ou la contraction du vérin. A tacking crosspiece according to the invention comprises two rollers each rotating around an axis supported by a yoke, and it is characterized in that at least one of the two yokes has its base articulated around a fixed axis of the cross member, while it is provided with a lateral arm that is rigidly secured to the flanges, and the end of which bears on a jack otherwise supported by the fixed cross member, means being provided for controlling the elongation or contraction of the cylinder.

Suivant une autre caractéristique de l'invention , la commande du vérin est effectuée à partir d'une pompe à main , si bien qu'un homme seul peut opérer facilement sur place , les opérations de basculement de la chape ett de son galet autour de leur axe d'oscillation fixe , et ceci même lorsque le galet supporte le poids de la virole. According to another characteristic of the invention, the actuator is operated from a hand pump, so that a single man can easily operate on site, the operations of tilting the yoke and its roller around their fixed axis of oscillation, even when the roller supports the weight of the shell.

Le dessin annexé , donné à titre d'exemple non limitatif , permettra de mieux comprendre les caractéristiques de l'invention. The appended drawing, given by way of nonlimiting example, will allow a better understanding of the characteristics of the invention.

Figure 1 est une vue d'ensemble montrant deux viroles qu'on se propose d'accoster , chacune d'elles reposant sur les quatre galets de son vireur. Figure 1 is an overall view showing two ferrules that it is proposed to dock, each of them resting on the four rollers of its tacker.

Figure 2 est une coupe transversale d'une virole , pratiquée au niveau d'une traverse de son vireur. Figure 2 is a cross section of a ferrule, made at a cross of its tacker.

On a rreprésenté sur les dessins deux viroles de chaudronnerie 1 et 2 , qu'on se propose d'accoster, c'est-à-dire de positionner exactement l'une par rapport à 1' autre , avant de les assembler par soudage de leurs bords en regard 3 et 4 . Chaque virole 1 et 2 repose sur les quatre galets 6 d'un vireur 5 . Chaque vireur 5 est constitué par deux traverses 7 dont chacune est équipée d'une paire de galets 6 . Le détail d'une traverse 7 apparaît sur la figure 2. We have represented in the drawings two boiler shells 1 and 2, which we propose to dock, that is to say to position exactly one with respect to the other, before assembling them by welding of their edges opposite 3 and 4. Each ferrule 1 and 2 rests on the four rollers 6 of a tacker 5. Each tacker 5 is made up of two crosspieces 7, each of which is fitted with a pair of rollers 6. The detail of a cross member 7 appears in FIG. 2.

Chaque galet 6 tourne fou autour d'un axe 8 dont les extrémités sont portées par la partie supérieure des flasques 9 d'une chape 10 . La base de cette chape 10 est articulée sur un axe 11 , monté à poste fixe sur la traverse 7 . Par ail- leurs , la chape 10 est prolongée latéralement par un bras 12 , dont l'extrémité reçoit la poussée d'un vérin 13. Ce dernier prend par ailleurs appui sur la traverse 7
Le vérin 13 est préférablement relié à un boîtier de commande 14 , compren#ant une pompe à main , que l'opérateur peut actionner en agissant sur un levier oscillant 15 .Autrement dit - si l'opérateur actionne le levier 15 pour pomper , il provo
que l'allongement du vérin 13 qui soulève le bras 12 > et
fait par conséquent basculer 1 'axe 8 du galet 6 autour
de l'axe 11 , dans le sens indiqué sur la figure 2 par la
flèche 16 - par contre , si l'opérateur actionne le boîtier de commande
14 de façon à relâcher la pression dans le vérin 13 , ce
lui-ci se contracte sous l'effet du poids de la virole 1
ou 2 et l'axe 8 du galet 6 bascule autour de l'axe 11 dans
le sens indiqué par la flèche 17.Each roller 6 turns madly around an axis 8, the ends of which are carried by the upper part of the flanges 9 of a yoke 10. The base of this yoke 10 is articulated on an axis 11, mounted on a fixed post on the cross-member 7. In addition, the yoke 10 is extended laterally by an arm 12, the end of which receives the thrust of a jack 13. The latter also bears on the cross-member 7
The jack 13 is preferably connected to a control unit 14, comprising a hand pump, which the operator can actuate by acting on an oscillating lever 15. In other words - if the operator actuates the lever 15 to pump, it provo
that the extension of the jack 13 which raises the arm 12> and
consequently causes the axis 8 of the roller 6 to tilt around
axis 11, in the direction shown in Figure 2 by the
arrow 16 - on the other hand, if the operator actuates the control unit
14 so as to release the pressure in the cylinder 13, this
it contracts under the effect of the weight of the shell 1
or 2 and the axis 8 of the roller 6 rocks around the axis 11 in
the direction indicated by the arrow 17.

l'utilisation du boîtier de commande 14 permet donc à un opérateur seul de déplacer l'axe 8 du galet 6 suivant une trajectoire en arc de cercle centré sur l'axe fixe 11 . Il en résulte pour la virole 1 ou 2 de petits déplacements permettant de la positionner avec précision , no
tamment avant soudage.0n comprend que le dispositif selon 1' invention permette à un opérateur seul d'effectuer ces opérations sans fournir d'efforts importants , et sans requérir l'utilisation d'autres moyens de levage. the use of the control box 14 therefore allows a single operator to move the axis 8 of the roller 6 along a trajectory in an arc centered on the fixed axis 11. This results in small displacements for the ferrule 1 or 2 allowing it to be positioned precisely, no
So much before welding. It is understood that the device according to the invention allows a single operator to carry out these operations without providing significant efforts, and without requiring the use of other lifting means.
