Description

ta présente invention est relative aux crémaillères entrant dans la construction de jambes de plate-formes pour forages pétroliers en mer. your present invention relates to racks used in the construction of platform legs for offshore oil drilling.

Les plate-formes de ce type sont généralement constituées d'une coque montée sur des jambes composées ou non de membrures plantées dans le fond du site sur lequel doit avoir lieu le forage. ladite coque étant déplaçable le long des jambes de la plateforme au moyen de mécanismes de levage solidaires de la coque et comportant des pignons de sortie coopérant avec des crémaillères montées sur une partie au moins de la longueur des jambes. Platforms of this type generally consist of a hull mounted on legs composed or not of members planted in the bottom of the site on which the drilling is to take place. said hull being movable along the legs of the platform by means of lifting mechanisms integral with the hull and comprising output pinions cooperating with racks mounted on at least part of the length of the legs.

Les crémaillères connues sont des pièces massives usinées montés dans des fentes longitudinales ménagées dans les jambes. Ce sont donc des pièces d un coüt relativement élevé. Known racks are machined solid parts mounted in longitudinal slots in the legs. They are therefore parts of a relatively high cost.

Compte tenu de la longueur importante de crémaillères nécessaire pour chaque jambe de la plateforme. notamment lorsque chaque jambe comporte deux crémaillères diamétralement opposées. le prix de ze- vient des jambes de plate-formes s en trouve considé- rablement accru. Given the large length of racks required for each leg of the platform. especially when each leg has two diametrically opposite racks. the price of the platform legs is considerably increased.

L invention vise à remédier à cet inconvé- nient en créant une construction de pilier. notamment de jambe de plate-forme pétrolière qui soit relativement simple et de ce fait d'un prix de revient réduit par rapport aux constructions de la technique antérieure. The invention aims to remedy this drawback by creating a pillar construction. in particular an oil platform leg which is relatively simple and therefore of a reduced cost price compared to the constructions of the prior art.

Elle a donc pour objet un pilier. notamment une jambe pour plate-forme de forage pétrolier. constitube par un corps tubulaire dans au moins une por tion longitudinale de laquelle est montée une cré maillera destinée à coopérer avec des pignons de sortie d un mécanisme de levage de la coque de la plate-forme. caractérisé en ce que ladite crémaillère est c3nstituce par une échelle dont les barreaux sont fixés audit corps tubulaire. Its object is therefore a pillar. in particular a leg for an oil drilling platform. constitubed by a tubular body in at least one longitudinal por tion from which is mounted a cre mesh designed to cooperate with output gears of a mechanism for lifting the hull of the platform. characterized in that said rack is c3nstituce by a ladder whose bars are fixed to said tubular body.

La jambe ou membrure de jambe de la plateforme de forage petrolier représentée à la Fig.1. The leg or leg frame of the oil drilling platform shown in Fig. 1.

comporte un corps tubulaire 1 formé de deux portions de cylindre creuses 2 dont les concavités sont dirigées l'une vers l autre. Les portions de cylindre 2 sont renforcées par des plaques longitudinales 3 dont les bords sont fixés aux bords des portions de cylindres 2 par des- cordons de soudure 4. Entre les plaques 3 de renforcement des portions de cylindres 2 est ménagé un espace 5 dans lequel est logée une crémaillère 6. Cette crémaillère est constituée par une série de barreaux cylindriques 7 disposés à intervalles réguliers et pourvus de prolongements axiaux 8 de plus petit diamètre engagés dans des trous 9 ménagés dans les plaques de renforcement 3.Les barreaux 7 constituent ainsi une crémaillère en forme d échelle avec laquelle peut engréner un pignon du type de ceux représentés à la Fig.5.comprises a tubular body 1 formed by two hollow cylinder portions 2, the concavities of which are directed towards one another. The cylinder portions 2 are reinforced by longitudinal plates 3, the edges of which are fixed to the edges of the cylinder portions 2 by weld beads 4. Between the plates 3 for reinforcing the cylinder portions 2 is a space 5 in which is housed a rack 6. This rack is constituted by a series of cylindrical bars 7 arranged at regular intervals and provided with axial extensions 8 of smaller diameter engaged in holes 9 formed in the reinforcing plates 3. The bars 7 thus constitute a ladder-shaped rack with which a pinion of the type shown in Fig. 5 can mesh.

Dans le mode de réalisation de la Fig.1. les barreaux 7 sont fixés dans les plaques de renforcement 9 des portions de cylindre 2 à proximité de l'un des bords de 1 espace 5 délimite par lesdites plaques. Les barreaux sont par exemple soudés en 10 aux plaques de renforcement 3 dans leurs zones de contact avec lesdites plaques. In the embodiment of Fig. 1. the bars 7 are fixed in the reinforcing plates 9 of the cylinder portions 2 near one of the edges of 1 space 5 delimited by said plates. The bars are for example welded at 10 to the reinforcing plates 3 in their contact zones with said plates.

La jambe ou membrure de jambe représentée à la Fig.1 est complétée par des entretoises 11 disposées à intervalles réguliers à proximité du bord de l'espace 5 opposé à la crémaillère 6. Les entretoises sont constituées par des rouleaux 12 comportant des embouts 13 engagés dans des trous 14 ménagés dans les plaques de renforcement 3 et traversés par des pasages 15 pour des boulons 16 cooperant avec les écrous de serrage 17 avec interposition de rondelles 18. The leg or leg member shown in Fig.1 is completed by spacers 11 arranged at regular intervals near the edge of the space 5 opposite the rack 6. The spacers are constituted by rollers 12 having end pieces 13 engaged in holes 14 made in the reinforcement plates 3 and traversed by passages 15 for bolts 16 cooperating with the tightening nuts 17 with the interposition of washers 18.

La jambe ou membrure de jambe de la plateforme représentée à la Fig.2 est analogue à celle de la Fig.1 à l'exception du fait que les plaques de renforcement des portions de cylindre 2 du corps tubulaire de la jambe sont formées chacune de deux demi-plaques 20,21 dont les bords extérieurs sont soudés par des cordons 22 aux bords correspondants des portions de cylindre 2 et dont les bords intérieurs sont soudés entre eux par des cordons 24 et également à un voile axial de renforcement 25. The leg or leg member of the platform shown in Fig. 2 is similar to that of Fig. 1 except that the reinforcing plates of the cylinder portions 2 of the tubular body of the leg are each formed of two half-plates 20, 21 whose outer edges are welded by cords 22 to the corresponding edges of the cylinder portions 2 and whose inner edges are welded together by cords 24 and also to an axial reinforcement web 25.

La jambe ou nembrure de jambe de la plateforme représentée à la Fig.3 comporte elle aussi un corps tubulaire formé de deux portions de cylindre 2.  The leg or leg nembrure of the platform shown in Fig.3 also has a tubular body formed by two cylinder portions 2.

Des plaques de renforcement de ces partions de cylindre sont formees chacune de deux demi-plaques 26.27 dont les bords extérieurs sont soudés par des cordons de soudure 28,29 aux bords correspondants des portions de cylindre et dont les bords intérieurs sont fixés par les cordons de soudure 30 et 31 à un voile de renforcement axial 32. A proximité de chacun des bords de espace 33 ménagé entre les plaques de renforcement 26,27, sont disposées deux crémaillères formees chacune de barreaux 34,35 disposés à intervalles réguliers et pourvus de prolongements axiaux de plus petit diamètre respectifs 36.37 engagés dans des trous correspondants prévus dans les plaques de renforcement. Les barreaux 34,35 de forme cylindrique sont fixés par soudage aux plaques 26,27 dans leurs zone de contact avec lesdites plaques.Reinforcement plates for these cylinder partitions are each formed from two half-plates 26.27, the outer edges of which are welded by weld beads 28, 29 to the corresponding edges of the cylinder portions and the inner edges of which are fixed by the beads of welding 30 and 31 to an axial reinforcement veil 32. Near each of the edges of the space 33 formed between the reinforcement plates 26, 27 are arranged two racks, each formed by bars 34, 35 arranged at regular intervals and provided with extensions respective smaller diameters 36.37 engaged in corresponding holes provided in the reinforcing plates. The rods 34, 35 of cylindrical shape are fixed by welding to the plates 26, 27 in their zone of contact with said plates.

La jambe ou membrure de jambe de la plateforme représentée à la Fig.4 diffère essentiellement de celle de la Fig.3 en ce que la partie centrale de renforcement de la jambe est constituée par une cornière en I 40 dont les extrémités des ailes sont soudées par des cordons 41 à des plaques longitudinales 42 de faible largeur qui s'étendent jusqu'au bord correspondant des portions de cylindre 2 et qui sont soudés à ces bords par des cordons de soudure 43. The leg or leg member of the platform shown in Fig. 4 differs essentially from that of Fig. 3 in that the central part of the leg reinforcement is constituted by an I-angle iron 40 whose ends of the wings are welded by beads 41 to longitudinal plates 42 of small width which extend to the corresponding edge of the cylinder portions 2 and which are welded to these edges by weld beads 43.

Lame de la cornière 40 forme entretoise de renforcement. Les barreaux 44 et 45 de chacune des deux crémaillères en échelle prévues dans cette jambe étant fixés de la meme manière que précédemment entre les plaques 42 disposées en regard l'une de l'autre.Angle bar 40 form reinforcement spacer. The bars 44 and 45 of each of the two ladder racks provided in this leg being fixed in the same manner as above between the plates 42 arranged opposite one another.

La Fig.5 montre schematiquement une jambe ou membrure de jambe de la plate-forme pourvue de deux crémaillères en echelle du type décrit à la Fig.4 et dont les barreaux 44 et 45 coopèrent avec des pignons 46,47 de sortie de mécanisme de levage de la plate forme non représentés. Fig.5 shows schematically a leg or leg frame of the platform provided with two ladder racks of the type described in Fig.4 and whose bars 44 and 45 cooperate with pinions 46,47 output mechanism lifting of the platform not shown.

On voit que l'agencement qui vient entre décrit permet d obtenir rapidement sans usinage des cremaillêres incorporées par construction aux jambes de force de plate-formes pour forages pétroliers. Les crémaillères en échelle comportent des barreaux cylindriques de sorte que les pignons destines à coopérer avec de telles crémaillères présentent des formes complémentaires de manière à assurer un bon engrénement.  It can be seen that the arrangement which comes between described makes it possible to quickly obtain without machining the racks incorporated by construction into the struts of platforms for oil drilling. The ladder racks have cylindrical bars so that the pinions intended to cooperate with such racks have complementary shapes so as to ensure good meshing.
