Abstract
Description
La présente invention est relative à un nouvel ap- pareil d'assemblage de tubes bout à bout par centrage, notamment pour la realisation de tuyauteries ou de canalisations de grande longueur, telles que canalisations de gaz, de petrole ou d'autres produits. The present invention relates to a new device for assembling tubes end to end by centering, in particular for the production of pipelines or pipelines of great length, such as gas, oil or other products.
Les tuyauteries ou les canalisations de grande longueur sont réalisées par soudage bout à bout d'un grand nombre de tubes de longueurs donnees. Toutefois, pour permettre le soudage correct de tels tubes bout à bout il est necessaire de maintenir les extrémités des tubes en regard rigoureusement bout à bout dans le meme axe.Les moyens de maintien proposes conformement à l'Art anterieur sont, globalement, de deux types : - des moyens de maintien exterieurs tels que des colliers, qui constituent une gêne pour l'execution de la soudure ; - et des moyens de maintien intérieurs qui comportent des verins pneumatiques ou hydrauliques ; ces derniers constituent cependant des appareillages très compliques qui necessitent beaucoup d'usinage et sont très coûteux ; en outre, il présentent un grand encombrement et ne sont approprie#s qu'à l'assemblage bout à bout de canalisations de grand diamètre. Par suite, les moyens de maintien interieurs proposes conformement à l'Art anterieur ne conviennent pas à l'assemblage bout à bout de tubes de petit diamètre, et notamment de tubes de 150 mm de diamètre. Long pipes or pipelines are made by butt welding of a large number of tubes of given lengths. However, to allow the correct welding of such tubes end to end it is necessary to keep the ends of the tubes facing each other rigorously end to end in the same axis. The means of maintenance proposed in accordance with the prior art are, overall, two types: - external holding means such as collars, which constitute a hindrance for the execution of the weld; - And interior holding means which include pneumatic or hydraulic cylinders; the latter however constitute very complicated apparatuses which require a lot of machining and are very expensive; in addition, they have a large footprint and are only suitable # s for the end-to-end assembly of large diameter pipes. Consequently, the internal holding means proposed in accordance with the prior art are not suitable for the end-to-end assembly of tubes of small diameter, and in particular of tubes of 150 mm in diameter.
La présente invention a en conse#quence pour but de pourvoir à un appareil d'assemblage de tubes bout à bout par centrage de ceux-ci par l'interieur, qui répond mieux aux ne- cessites de la pratique que les dispositifs d'assemblage de tubes proposes dans l'Art anterieur, notamment en ce qu'il permet l'assemblage de tubes de diamètres variables dans de larges limites, en ce qu'il est d'un prix de revient relativement bas, d'une grande simplicité de construction et, partant, très robuste, en ce qu'il est peu encombrant, en ce qu'il réalise un assemblage bout à bout centre# de façon parfaite et en ce qu'il permet une accessibilite# totale pour l'execution de la soudure. The object of the present invention is therefore to provide an apparatus for assembling tubes end to end by centering them from the inside, which responds better to the needs of the practice than assembly devices. of tubes proposed in the prior art, in particular in that it allows the assembly of tubes of variable diameters within wide limits, in that it is a relatively low cost price, very simple to construction and, therefore, very robust, in that it is not bulky, in that it performs a center butt assembly # perfectly and in that it allows total accessibility # for the execution of the welding.
La pre#sente invention a pour objet un appareil d'assemblage de tubes bout à bout par centrage de ceux-ci par l'interieur, qui est caracterise en ce qu'il comprend une cage rigide de support qui porte une paire de flasques interieurs fixes qui reçoivent des barreaux de centrage, et une paire de flasques intermediaires mobiles par rapport aux flasques interieurs, lesquels flasques intermediaires sont relie#s auxdits barreaux de centrage par l'intermediaire de biellettes ou analogues, et en ce que le deplacement des flasques intermediaires par rapport aux flasques interieurs fixes est commanda par une tige de commande solidaire desdits flasques intermediaires, qu'elle traverse axialement, et dont la manoeuvre est realisee à l'aide d'un organe de commande approprie tel que volant ou manivelle, notamment. The present invention relates to an apparatus for assembling tubes end to end by centering them by the interior, which is characterized in that it comprises a rigid support cage which carries a pair of interior flanges. fixed receiving centering bars, and a pair of intermediate flanges movable relative to the inner flanges, which intermediate flanges are connected # s to said centering bars by means of rods or the like, and in that the displacement of the intermediate flanges relative to the fixed inner flanges is controlled by a control rod integral with said intermediate flanges, which it passes axially, and the operation of which is carried out using an appropriate control member such as a steering wheel or crank, in particular.
Selon un mode de reaalisation avantageux de l'appareil conforme à l'invention, les flasques intérieurs comportent des voies de guidage, de preference sensiblement radiales, dans lesquelles les barreaux de centrage coulissent sous l'effet du deplacement des flasques intermediaires, qui leur est transmis par lesdites biellettes. According to an advantageous embodiment of the device according to the invention, the inner flanges include guide tracks, preferably substantially radial, in which the centering bars slide under the effect of the displacement of the intermediate flanges, which is their transmitted by said links.
Selon un autre mode de realisation avantageux de l'appareil conforme à l'invention, chaque barreau de centrage porte au moins une projection qui s'étend dans un plan sensiblement perpendiculaire au plan dudit barreau de centrage et qui presente la forme d'un segment d'arc de cercle, laquelle projection est entraînez conjointement avec ledit barreau dans la voie de guidage managée dans le flasque interieur correspondant, pour être amende dans une position qui correspond au diamètre intérieur des tubes à abouter. According to another advantageous embodiment of the apparatus according to the invention, each centering bar carries at least one projection which extends in a plane substantially perpendicular to the plane of said centering bar and which has the shape of a segment of an arc of a circle, which projection is driven jointly with said bar in the guide track managed in the corresponding inner flange, to be fine in a position which corresponds to the inside diameter of the tubes to be butted.
Selon une disposition avantageuse de ce mode de realisation, le segment d'arc de cercle porte par chaque barreau de centrage a une courbure egale au diamètre interieur du tube à assembler. According to an advantageous arrangement of this embodiment, the circular arc segment carried by each centering bar has a curvature equal to the inside diameter of the tube to be assembled.
Selon encore un autre mode de realisation avantageux de l'appareil conforme à l'invention, le barreau de centrage situe en position haute de l'appareil porte un element de support d'une pige pour le centrage de l'appareil. According to yet another advantageous embodiment of the apparatus according to the invention, the centering bar situated in the high position of the apparatus carries a support element for a rod for centering the apparatus.
Selon un autre mode de re#alisation avantageux deappareil conforme à l'invention, les barreaux de centrage comportent dans leur zone comprise entre les deux flasques inte- rieurs fixes, un evidement propre à permettre la penetration totale de la soudure. According to another advantageous embodiment of the apparatus according to the invention, the centering bars include in their zone between the two fixed inner flanges, a recess capable of permitting total penetration of the weld.
Selon encore un autre mode de realisation avantageux de l'appareil conforme à l'invention, la cage rigide de support comprend deux flasques d'extremite solidairises entre eux par une pluralité d'axes fixes parallèles entre eux et perpendiculaires au plan desdits flasques d'extremite, lesquels portent des galets de translation de l'appareil à l'in trieur des tubes à abouter ou aboutes. According to yet another advantageous embodiment of the apparatus according to the invention, the rigid support cage comprises two end flanges secured to each other by a plurality of fixed axes parallel to each other and perpendicular to the plane of said flanges of extremity, which carry translation rollers from the device to the sorter of the butted or butted tubes.
Suivant une disposition preeree de ce mode de r4a- lisation, chacun des galets de translation est monté dans un support solidaire de chacun des flasques d'extremite et pourvu de moyens de réglage en position de l'axe de rotation du galet de translation, pour ajuster l'appareil conforme à l'invention aux differences de diamètres des tubes à abouter. According to a preferred arrangement of this embodiment, each of the translation rollers is mounted in a support integral with each of the end flanges and provided with means for adjusting the position of the axis of rotation of the translation roller, for adjust the device according to the invention to the differences in diameter of the tubes to be butted.
Selon une modalite avantageuse de cette disposition, lesdits moyens de réglage sont constitues par un trou oblong comportant une pluralite de positions pour l'axe du galet, qui correspondent chacune à un diamètre de tubes à abouter et dans lesquelles ledit axe est bloque# par un ecrou. According to an advantageous modality of this arrangement, said adjustment means are constituted by an oblong hole comprising a plurality of positions for the axis of the roller, which each correspond to a diameter of tubes to be butted and in which said axis is blocked # by a nut.
En variante, lesdits moyens de reglage sont consitues par un ressort calibre ou par un système de butees. As a variant, said adjustment means are constituted by a caliber spring or by a system of stops.
Outre les dispositions qui pre#cèdent, l'invention comprend encore d'autres dispositions, qui ressortiront de la description qui va suivre. In addition to the foregoing provisions, the invention also comprises other provisions, which will emerge from the description which follows.
La presente invention vise plus particulièrement les appareils d'assemblage de tubes bout à bout par centrage par l'interieur des tubes, conformes aux dispositions qui pre#cèdent, ainsi que les postes de soudure de canalisations équipes de tels appareils. The present invention relates more particularly to devices for assembling tubes end to end by centering by the interior of the tubes, in accordance with the provisions which precede #, as well as the welding stations for pipes fitted with such devices.

- la figure 1 est une vue de cote dlun mode de rea- lisation de l'appareil conforme à la présente invention,
- la figure 2 est une vue en bout, du côte de la tringlerie de commande de l'appareil de la figure 1, et
- la figure 3 est une vue en perspective d'un barreau de centrage.The invention will be better understood using the additional description which follows, which refers to the accompanying drawings in which
FIG. 1 is a side view of an embodiment of the apparatus according to the present invention,
FIG. 2 is an end view, from the side of the control linkage of the device in FIG. 1, and

Il doit être bien entendu, toutefois, que ces dessins et les parties descriptives correspondantes, sont donnes uniquement à titre d'illustration de l'objet de l'invention, dont ils ne constituent en aucune mantière une limitation. It should be understood, however, that these drawings and the corresponding descriptive parts, are given solely by way of illustration of the subject of the invention, of which they do not in any way constitute a limitation.
L'appareil conforme à l'invention tel que represente# aux dessins, comprend une cage rigide de support constituee par des flasques d'extremite 2 et 3 relies entre eux par des axes fixes 1 dont le nombre est variable en fonction de la gamme de diamètres interieurs de tubes qu'il est destine à abouter ; c'est ainsi que l'appareil destine à abouter des tubes conformes à l'invention, peut abouter des tubes de tous diamètres compris entre 150 et 450 mm, notamment ; il peut comporter, comme dans l'exemple represente, trois axes 1 dispose#s à 1200 l'un de l'autre ou un nombre d'axes different, 1, 4 ou 6 par exemple, pour former une cage de support d'une rigidite suffisante. The apparatus according to the invention as shown in the drawings, comprises a rigid support cage constituted by end flanges 2 and 3 connected together by fixed axes 1, the number of which varies according to the range of internal diameters of tubes which it is intended to abut; this is how the apparatus intended to abut tubes in accordance with the invention, can abut tubes of all diameters between 150 and 450 mm, in particular; it can include, as in the example shown, three axes 1 has # s at 1200 from one another or a different number of axes, 1, 4 or 6 for example, to form a support cage for sufficient rigidity.
La cage rigide de support 1-2-3 porte une paire de flasques intérieurs 4-5 fixes qui presentent chacun deux voies de guidage, à savoir une voie de guidage radiale 6 èn partie inférieure et une voie de guidage radiale en partie supérieure (non visible à la figure 1). The rigid support cage 1-2-3 carries a pair of fixed inner flanges 4-5 which each have two guide tracks, namely a radial guide track 6 in the lower part and a radial guide track in the upper part (not visible in Figure 1).
Ladite cage de support porte en outre une paire de flasques intermediaires 7-8 mobiles dont chacun porte sur sa face interieure une projection 9 sur laquelle est fixée à pivotement autour de l'axe 10, une biellette 11 dont l'extr4mi- te# opposee est fixee, également à pivotement autour de l'axe 13, à une extremite d'un barreau de centrage 14-15#qui est reçu dans la voie de guidage 6 correspondante ménagée dans chacun des flasques intérieurs 4 5
Chaque barreau de centrage 14-15 porte deux projections 16-17 presentant la forme d'un segment d'arc de cercle, dont chacune vient en butée contré la face interne correspondante du flasque interieur 4-5.Le barreau de centrage 14-15 comporte en outre dans sa zone comprise entre les flasques intérieurs 4-5, un evidement 18. Said support cage further carries a pair of movable intermediate flanges 7-8 each of which carries on its inner face a projection 9 on which is pivotally fixed around the axis 10, a rod 11 whose end # oppose is fixed, also pivotally about the axis 13, to one end of a centering bar 14-15 # which is received in the corresponding guide track 6 formed in each of the inner flanges 4 5
Each centering bar 14-15 carries two projections 16-17 having the shape of an arc segment, each of which abuts against the corresponding internal face of the inner flange 4-5. The centering bar 14-15 further includes in its area between the inner flanges 4-5, a recess 18.
De plus, le barreau de centrage superieur 14 comporte un 4le'ment de support, tel que le tube creux 19, destine à recevoir la pige de centrage (non representee) de l'appareil conforme à l'inventions
Le deplacement des flasques intermédiaires mobiles 7-8 par rapport aux flasques interieurs fixes 4-5, est commande au moyen d'un organe de commande extérieur 20, tel que manivelle ou volant par exemple, associe# par une tringlerie 21 à une tige de commande 22 qui traverse axialement les flasques intermediaires 7-8 à travers des orifices centraux menages dans ces derniers (non visibles aux dessins) ; la tige de commande 22 est visse au moyen de la vis 12 sur la fa ce externe du flasque intermediaire 7, le plus eloigne de l'organe de commande 20, et porte une butee 23 qui est montee dans une position telle sur ladite tige 22 qu'elle est susceptible de se deplacer entre la face interne du flasque d'extremite 3, le plus proche de l'organe de commande 20, et la face externe du flasque intermédiaire 8.In addition, the upper centering bar 14 includes a support element, such as the hollow tube 19, intended to receive the centering pin (not shown) of the apparatus according to the invention.
The displacement of the movable intermediate flanges 7-8 relative to the fixed interior flanges 4-5 is controlled by means of an external control member 20, such as a crank or flywheel for example, associated # by a linkage 21 with a rod of control 22 which passes axially through the intermediate flanges 7-8 through central orifices provided in the latter (not visible in the drawings); the control rod 22 is screwed by means of the screw 12 on the external face of the intermediate flange 7, the furthest from the control member 20, and carries a stop 23 which is mounted in such a position on said rod 22 that it is capable of moving between the internal face of the end flange 3, closest to the control member 20, and the external face of the intermediate flange 8.
Les flasques d'extrémité 2-3 portent des joues de support, 24-25 et 27-28 respectivement, entre lesquelles est monté un galet 26, 29, respectivement, de translation de l'appareil conforme à l'invention dans les tubes à abouter (non repre'sent4s). The end plates 2-3 carry support cheeks, 24-25 and 27-28 respectively, between which is mounted a roller 26, 29, respectively, for translating the apparatus according to the invention in the tubes to abut (not shown4s).
Dans le mode de realisation represente aux dessins, les joues de support 24-25 et 27-28 comportent un trou 30 pour le passage de l'axe de rotation 31 du galet de rotation 26 ou 29. La forme oblongue donnee à ce trou 30 permet le reglage en position dudit axe 31 pour ajuster l'appareil aux différences de diamètres des tubes à abouter, l'axe 31 etant ensuite bloqué dans la position choisie, au moyen d'un ecrou de serrage 32. L'on comprendra cependant aisement que tout autre moyen de reglage en position de l'axe 31 de rotation des galets de translation 26, 29 peut être utilise en variante du mode de realisation représente aux dessins, qui vient d'être decrit. In the embodiment shown in the drawings, the support cheeks 24-25 and 27-28 have a hole 30 for the passage of the axis of rotation 31 of the rotation roller 26 or 29. The oblong shape given to this hole 30 allows the adjustment in position of said axis 31 to adjust the device to the differences in diameters of the tubes to abut, the axis 31 then being locked in the chosen position, by means of a tightening nut 32. It will however be easily understood that any other means for adjusting the position of the axis 31 of rotation of the translation rollers 26, 29 can be used as a variant of the embodiment shown in the drawings, which has just been described.
Le fonctionnement de l'appareil d'assemblage de tubes bout à bout par centrage, qui vient d'être decrit dans ce qui precède, est le suivant
L'appareil conforme à l'invention est engage dans un premier tube, au moyen des galets de translation 26, 29.The operation of the apparatus for joining tubes end to end by centering, which has just been described in the foregoing, is as follows
The device according to the invention is engaged in a first tube, by means of the translation rollers 26, 29.
Lorsque appareil est mis en place dans le premier tube, une pige de centrage (non repr4sente'e) est mise en place dans l'element tubulaire creux 19 de support de la pige de centrage fixe au barreau de centrage superieur 14 ; le deuxième tube est alors engage côté tringlerie, autour de l'appareil jusqu'à ce qu'il arrive en butee contre ladite pige ; on enlève alors cette dernière pour commencer l'ope'ration d'assemblage par centrage bout-à-bout des deux tubes.When the device is placed in the first tube, a centering rod (not shown) is placed in the hollow tubular element 19 for supporting the centering rod fixed to the upper centering bar 14; the second tube is then engaged on the linkage side, around the apparatus until it abuts against said rod; the latter is then removed to start the assembly operation by centering the two tubes end-to-end.
Cette operation est realisee en manoeuvrant l'organe de commande 20 jusqu'à ce que la butee 23 heurte contre la face externe du flasque intermediaire 8 provoquant ainsi le placement des flasques intermediaires 7-8 en direction l'un de l'autre ; ce deplacement des flasques intermediaires 7-8 a pour effet de faire pivoter les biellettes 11 autour des axes 10 et 13, entraînant ainsi le coulissement des barreaux de centrage 14-15 dans les voies de guidage correspondantes 6 la course de coulissement des barreaux de centrage 14-15 et des projections 16-17 que portent ceux-ci, amène les projections 16-17 dans une position qui correspond au diamètre interieur des tubes à abouter. L'on comprendra ainsi aisément que la grandeur conferee par la manoeuvre de l'organe de commande 20 à la course de coulissement des barreaux de centrage 14-15 et des projections 16-17 qui leur sont associees, permet de faire varier la position desdites projections en fonction des différents diamètres des tubes à abouter. This operation is carried out by maneuvering the control member 20 until the stop 23 strikes against the external face of the intermediate flange 8 thus causing the placement of the intermediate flanges 7-8 in the direction of one another; this displacement of the intermediate flanges 7-8 has the effect of pivoting the rods 11 around the axes 10 and 13, thus causing the sliding of the centering bars 14-15 in the corresponding guide tracks 6 the sliding stroke of the centering bars 14-15 and the projections 16-17 which these bear, brings the projections 16-17 in a position which corresponds to the inside diameter of the tubes to be butted. It will thus be easily understood that the magnitude conferred by the operation of the control member 20 to the sliding stroke of the centering bars 14-15 and the projections 16-17 which are associated with them, makes it possible to vary the position of said projections according to the different diameters of the tubes to be butted.
Une fois les tubes centres et aboutes, ceux-ci sont en position pour la realisation de la soudure, qui est de preference realisee par pénetration et qui est grandement fa cilitee par la disposition de l'evidement 18 ménage dans les barreaux de centrage 14-15 dans la zone d'aboutement comprise entre les deux flasques interieurs 4-5 fixes. La grande accessibilite# à la zone d'aboutement permet de realiser la soudure des deux tubes aboutes, avec une grande facilite. Une fois la soudure realisee, l'appareil est retire des tubes aboutes, soudes, par manoeuvre de l'organe de commande 22, à l'aide des galets de translation 26, 29. Once the tubes are centered and butted, these are in position for carrying out the welding, which is preferably carried out by penetration and which is greatly facilitated by the arrangement of the recess 18 housed in the centering bars 14- 15 in the abutment area between the two fixed inner flanges 4-5. The great accessibility # to the abutment area allows the welding of the two butted tubes, with great ease. Once the welding has been carried out, the device is removed from the butted tubes, welded, by maneuvering the control member 22, using the translation rollers 26, 29.
L'appareil conforme à l'invention d'assemblage de tubes bout à bout par centrage, en vue de leur soudage, pour la realisation de canalisations de grande longueur, présente une grande souplesse d'utilisation en ce qu'il est adaptable à tous les diamètres de canalisations, des plus petits aux plus grands et en ce qu'il permet, du fait du coulissement réglable des barreaux de centrage 14-15, l'assemblage bout à bout par centrage non seulement de tubes à section sensiblement circulaire, mais également de tubes ovalises ou de tubes comportant des meplats. The apparatus according to the invention for assembling tubes end to end by centering, with a view to their welding, for the production of very long pipelines, has great flexibility of use in that it is adaptable to all the pipe diameters, from the smallest to the largest and in that it allows, due to the adjustable sliding of the centering bars 14-15, the end-to-end assembly by centering not only of tubes of substantially circular section, but also oval tubes or tubes with flats.
Ainsi que cela ressort de ce qui precède, l'invention ne se limite nullement à ceux de ses modes de realisation et d'application qui viennent d'être decrits de façon plus explicite ; elle en embrasse au contraire toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans slecarter du cadre, ni de la porte de la presente invention. As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework or from the door of the present invention.
