Description

La présente invention concerne une structure de mât hissable de véhicule sous-marin.The present invention relates to a hoistable structure of an underwater vehicle.

Un mât hissable, également appelé mât télescopique, est généralement destiné à porter des moyens de communication du véhicule sous-marin, tels que des antennes radio d'émission et/ou de réception, et/ou de porter des moyens d'exploration et de détection de l'environnement du véhicule sous-marin, tels que des antennes radars, des capteurs ou des périscopes.A hoistable mast, also called a telescopic mast, is generally intended to carry means of communication of the underwater vehicle, such as transmitting and / or receiving radio antennas, and / or carrying means of exploration and navigation. detecting the environment of the underwater vehicle, such as radar antennas, sensors or periscopes.

On connaît déjà dans l'état de la technique, notamment d'après FR 2 977 232 , une structure de mât de véhicule sous-marin comportant :

  • un mât hissable, comprenant une partie mobile en translation dans une direction de hissage, entre une position affalée et une position déployée,
  • au moins un support du mât, muni d'au moins un rail de guidage en translation de la partie mobile du mât dans la direction de hissage, et
  • des moyens de fixation du support sur une partie structurelle du véhicule sous-marin.
We already know in the state of the art, in particular according to FR 2 977 232 an underwater vehicle mast structure comprising:
  • a hoistable mast, comprising a part movable in translation in a hoisting direction, between a sloped position and an extended position,
  • at least one support of the mast, provided with at least one guide rail in translation of the movable part of the mast in the hoisting direction, and
  • means for fixing the support on a structural part of the underwater vehicle.

Dans cette structure de mât, chaque rail présente une section transversale en forme de U, comportant des parties latérales formant les branches du U.In this mast structure, each rail has a U-shaped cross section, with side portions forming the branches of the U.

Par ailleurs, la partie mobile du mât porte des patins de glissement, logés entre les parties latérales du rail et coulissant dans ce rail. Ainsi, les parties latérales du rail forment des butées pour chaque patin de glissement, immobilisant latéralement ce patin de glissement.Furthermore, the mobile part of the mast carries sliding pads, housed between the lateral parts of the rail and sliding in this rail. Thus, the lateral portions of the rail form stops for each sliding shoe, laterally immobilizing the sliding shoe.

Ainsi, les rails et patins présentent, en plus de la fonction de guidage du mât en translation le long de la direction de hissage, une fonction de reprise des efforts dans une direction latérale perpendiculaire à ladite direction de hissage.Thus, the rails and shoes have, in addition to the guide function of the mast in translation along the hoisting direction, a load recovery function in a lateral direction perpendicular to said hoisting direction.

Cette fonction de reprise des efforts permet au mât de résister aux contraintes extérieures, notamment aux contraintes appliquées par l'eau dans lequel se déplace le véhicule sous-marin lorsque le mât est hissé en position déployée.This effort recovery function allows the mast to withstand external stresses, including stresses applied by the water in which the underwater vehicle moves when the mast is hoisted in the deployed position.

L'inventeur a constaté que lesdits patins de glissement induisent un effort de frottement important lors du déplacement de la partie mobile du mât, représentant parfois plus de 60% des efforts résistant s'opposant au déplacement du mât.The inventor has found that said sliding pads induce a high friction force during the displacement of the movable part of the mast, sometimes representing more than 60% of the resistant forces opposing the movement of the mast.

Ainsi, les moyens d'entraînement en translation de la partie mobile du mât doivent être dimensionnés pour compenser ces efforts de frottement, ce qui implique un encombrement important de ces moyens d'entraînement, et une consommation énergétique importante.Thus, the translational drive means of the mobile part of the mast must be dimensioned to compensate for these friction forces, which implies a large size of these drive means, and a significant energy consumption.

L'invention a notamment pour but de remédier à ces inconvénients, en fournissant une structure de mât autorisant l'utilisation de moyens de guidage impliquant des efforts de frottement réduits, et cela sans réduire la qualité de la reprise des efforts appliqués sur le mât.The object of the invention is in particular to remedy these drawbacks, by providing a mast structure allowing the use of guiding means involving reduced frictional forces, without reducing the quality of the recovery of the forces applied to the mast.

A cet effet, la présente invention a notamment pour objet une structure de mât de véhicule sous-marin, comportant :

  • un mât hissable, comprenant une partie mobile en translation dans une direction de hissage, entre une position affalée et une position déployée, et
  • un support du mât, muni d'au moins un rail de guidage en translation de la partie mobile du mât dans la direction de hissage, ledit support s'étendant dans la direction de hissage entre une extrémité inférieure et une extrémité supérieure,
caractérisé en ce que :
  • la partie mobile du mât comporte un corps et des organes de guidage, portés par ce corps, lesdits organes de guidage coopérant avec le rail de guidage,
  • la structure de mât comporte des premiers moyens de reprise d'efforts dans au moins une seconde direction perpendiculaire à la direction de hissage, destinés à être solidarisés à une partie structurelle du véhicule sous-marin à proximité de l'extrémité supérieure du support, et destinés à former une butée, dans ladite seconde direction, pour le corps de la partie mobile du mât lorsque cette partie mobile est dans sa position déployée.
For this purpose, the subject of the present invention is in particular a submarine vehicle mast structure, comprising:
  • a hoistable mast, comprising a part movable in translation in a hoisting direction, between a sloped position and an extended position, and
  • a mast support, provided with at least one guide rail in translation of the movable portion of the mast in the hoisting direction, said support extending in the hoisting direction between a lower end and an upper end,
characterized in that
  • the mobile part of the mast comprises a body and guide members, carried by this body, said guide members cooperating with the guide rail,
  • the mast structure comprises first force recovery means in at least a second direction perpendicular to the hoisting direction, intended to be secured to a structural part of the underwater vehicle near the upper end of the support, and intended to form a stop, in said second direction, for the body of the mobile part of the mast when the moving part is in its deployed position.

L'inventeur a constaté que les contraintes extérieures sont principalement appliquées au mât lorsque celui-ci est en position déployée. En effet, durant le déplacement de la partie mobile du mât, le mât est moins exposé à ces contraintes que lorsqu'il est entièrement déployé, et la durée d'un tel déplacement est suffisamment réduite pour que les contraintes appliquées durant ce déplacement n'aient pas d'effet négatif sur la structure de mât.The inventor has found that the external stresses are mainly applied to the mast when it is in the deployed position. Indeed, during the displacement of the mobile part of the mast, the mast is less exposed to these constraints than when it is fully deployed, and the duration of such a displacement is sufficiently reduced so that the stresses applied during this displacement n ' have no negative effect on the mast structure.

Ainsi, la présente invention prévoit des moyens de reprise d'efforts solidarisés au massif du sous-marin, formant une butée pour le corps de la partie mobile du mât lorsque cette partie mobile est dans sa position déployée.Thus, the present invention provides force recovery means secured to the submarine body, forming a stop for the body of the movable part of the mast when the movable portion is in its deployed position.

La reprise d'efforts est donc convenablement assurée lorsque cela est principalement nécessaire, c'est-à-dire lorsque le mât est en position déployée.The recovery of efforts is therefore properly ensured when this is mainly necessary, that is to say when the mast is in the deployed position.

Par ailleurs, puisque les contraintes appliquées au mât durant son déplacement sont considérées comme étant peu nuisibles, l'invention permet d'utiliser des moyens de guidage simplifiés, puisque ne nécessitant pas de remplir une importante fonction de reprise des efforts.Moreover, since the stresses applied to the mast during its movement are considered as being only slightly harmful, the invention makes it possible to use simplified guiding means since it does not need to fulfill an important function of recovery of forces.

De tels moyens de guidage simplifiés peuvent par exemple comporter des organes de guidage roulant plutôt que glissant, ce qui implique peu d'efforts de frottement s'opposant au déplacement du mât.Such simplified guide means may for example comprise rolling guide members rather than sliding, which involves little friction efforts opposing the movement of the mast.

Une structure de mât selon l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables.

  • Les premiers moyens de reprise d'efforts comportent au moins un organe de reprise d'efforts, destiné à être solidarisés à ladite partie structurelle du véhicule sous-marin, et un organe de calage complémentaire, porté par le corps de la partie mobile et destiné à coopérer avec l'organe de reprise d'efforts.
  • Chaque organe de reprise d'efforts présente une première surface inclinée par rapport à la direction verticale, de manière à former une surface de butée s'opposant au déplacement de la partie mobile au-delà de sa position déployée, et l'organe de calage complémentaire présente une seconde surface inclinée par rapport à la direction verticale, sensiblement parallèle à la première surface, et destinée à coopérer avec la première surface lorsque la partie mobile est dans sa position déployée.

On a représenté sur la figure 1 une structure 10 de mât de véhicule sous-marin. Cette structure de mât 10 est destinée à être rapportée sur une partie structurelle 11 du véhicule sous-marin, également appelée massif 11.We have shown on the figure 1 a submarine vehicle mast structure 10. This mast structure 10 is intended to be attached to a structural part 11 of the underwater vehicle, also called solid mass 11.

La structure de mât 10 comporte un mât hissable 12 et un support 14 pour ce mât. Sur cette figure 1, le mât 12 est représenté en position déployée, également appelée position hissée. En effet, le mât 12 comporte une partie mobile 22, déplaçable en translation dans une direction de hissage Z, entre une position affalée et une position déployée. Cette partie mobile 22 comporte un équipement 13, comprenant par exemple des moyens de communication ou d'exploration.The mast structure 10 comprises a hoistable mast 12 and a support 14 for this mast. On this figure 1 , the mast 12 is shown in the deployed position, also called hoisted position. Indeed, the mast 12 comprises a movable portion 22, movable in translation in a hoisting direction Z, between a sloped position and an extended position. This mobile part 22 comprises an equipment 13, comprising, for example, communication or exploration means.

Le support 14 s'étend dans la direction de hissage Z, entre une extrémité inférieure (non représentée) et une extrémité supérieure 14B. Le support 14 comporte par exemple deux montants latéraux 15 sensiblement identiques, agencés l'un en regard de l'autre dans une direction Y transversale perpendiculaire à la direction de hissage Z, le mât 12 étant agencé entre ces montants latéraux 15 dans cette direction transversale Y. Dans l'exemple représenté, les montants latéraux 15 sont séparés, mais ils pourraient en variante être reliés par des traverses ou par un ou deux montants transversaux.The support 14 extends in the Z hoisting direction, between a lower end (not shown) and an upper end 14B. The support 14 comprises for example two substantially identical lateral uprights 15 arranged one facing each other in a transverse Y direction perpendicular to the hoisting direction Z, the mast 12 being arranged between these lateral uprights 15 in this transverse direction Y. In the example shown, the lateral uprights 15 are separated, but they could alternatively be connected by sleepers or by one or two transverse uprights.

Chaque montant 15 comporte des moyens de fixation sur la partie structurelle 11 du véhicule sous-marin.Each upright 15 has fastening means on the structural part 11 of the underwater vehicle.

Le mât 12 est relié au support 14, et plus particulièrement à chaque montant 15, par l'intermédiaire de moyens 16 de guidage du mât en translation dans une direction de hissage Z, pour le hissage et l'affalage de ce mât 12.The mast 12 is connected to the support 14, and more particularly to each upright 15, by means 16 for guiding the mast in translation in a hoisting direction Z, for hoisting and lowering this mast 12.

Les moyens de guidage 16 comportent des rails de guidage 18, portés par le support 14 et s'étendant dans la direction de hissage Z. Plus particulièrement, chaque montant 15 porte au moins un rail de guidage 18 respectif. Ainsi, la structure de mât 10 comporte deux rails de guidage 18, agencés l'un en regard de l'autre dans la direction transversale Y.The guide means 16 comprise guide rails 18 carried by the support 14 and extending in the hoisting direction Z. More particularly, each upright 15 carries at least one guide rail 18 respectively. Thus, the mast structure 10 comprises two guide rails 18, arranged one opposite the other in the transverse direction Y.

Les moyens de guidage 16 comportent, pour chaque rail de guidage 18, au moins un élément 20 de guidage complémentaire, porté par le mât 12, et destiné à coopérer avec ce rail 18.The guide means 16 comprise, for each guide rail 18, at least one complementary guiding element 20, carried by the mast 12, and intended to cooperate with this rail 18.

Plus particulièrement, les éléments de guidage 20 sont portés par un corps 26 de la partie mobile 22 du mât 12.More particularly, the guide elements 20 are carried by a body 26 of the mobile part 22 of the mast 12.

Avantageusement, ladite partie mobile 22 porte, pour chaque rail 18, un organe de guidage 20 supérieur et un organe de guidage 20 inférieur, agencés à une distance prédéterminée l'un de l'autre dans la direction de hissage Z. Cette distance prédéterminée permet une bonne stabilisation du mât 12, et le maintien de ce mât 12 parallèlement à la direction de hissage Z. Habituellement, ladite distance prédéterminée est supérieure ou égale à 1 mètre.Advantageously, said movable portion 22 carries, for each rail 18, an upper guide member 20 and a lower guide member 20, arranged at a predetermined distance from each other in the direction of hoisting Z. This predetermined distance allows a good stabilization of the mast 12, and maintaining the mast 12 parallel to the hoisting direction Z. Usually, said predetermined distance is greater than or equal to 1 meter.

Dans l'exemple représenté, chaque rail de guidage 18 présente une section transversale en U, comprenant une piste de roulement sensiblement plane.In the example shown, each guide rail 18 has a U-shaped cross section, comprising a substantially flat raceway.

Chaque organe de guidage 20 comporte au moins un élément de roulement 28, porté par le corps 26, agencé en contact de la piste de roulement du rail 18 et destiné à rouler sur celle-ci dans la direction de hissage Z. Ainsi, cet élément de roulement 28 présente une partie de roulement mobile en rotation autour d'un axe perpendiculaire à la direction de hissage, et sensiblement parallèle à la piste de roulement. Cette partie de roulement est de préférence réalisée en polyuréthane, afin de ne générer que peu de bruit lors de son roulement sur la piste de roulement.Each guide member 20 comprises at least one rolling element 28, carried by the body 26, arranged in contact with the rolling track of the rail 18 and intended to roll on it in the hoisting direction Z. Thus, this element rolling bearing 28 has a rolling portion rotatable about an axis perpendicular to the hoisting direction, and substantially parallel to the raceway. This rolling part is preferably made of polyurethane, so as to generate little noise during its rolling on the raceway.

Plus particulièrement, chaque organe de guidage 20 comporte avantageusement deux éléments de roulement 28, et un élément de support 32, comme cela est représenté sur la figure 2. Chaque élément de roulement 28 est relié au premier élément de support 32 par une liaison pivot 34 respective autour dudit axe de rotation A.More particularly, each guide member 20 advantageously comprises two rolling elements 28, and a support element 32, as shown in FIG. figure 2 . Each rolling element 28 is connected to the first support member 32 by a respective pivot connection 34 about said axis of rotation A.

En outre, l'élément de support 32 est relié au corps 26 par une liaison pivot 36 autour d'un axe sensiblement parallèle aux axes de rotation A des éléments de roulement.In addition, the support member 32 is connected to the body 26 by a pivot connection 36 about an axis substantially parallel to the axes of rotation A of the rolling elements.

Avantageusement, chaque organe de guidage 20 comporte des moyens élastiques 38 de stabilisation, à effet de compression, s'étendant entre l'élément de support 32 et un organe d'appui (non représenté) porté par le corps 26, de manière à appliquer un effort de pression sur les éléments de roulement portés par cet élément de support, contre la piste de roulement correspondante.Advantageously, each guide member 20 comprises resilient compression means 38 extending between the support member 32 and a support member (not shown) carried by the body 26 so as to apply a pressure force on the rolling elements carried by this support element against the corresponding raceway.

Les moyens élastiques de stabilisation 38 comportent par exemple, pour chaque élément de roulement portés par cet élément de support correspondant, un organe élastique à effet de compression 40, s'étendant entre un premier siège porté par ledit organe d'appui, et un second siège porté par l'élément de support à proximité de cet élément de roulement.The elastic stabilizing means 38 comprise, for example, for each rolling element carried by this corresponding support member, an elastic member with a compression effect 40 extending between a first seat carried by said support member, and a second seat carried by the support member near this rolling element.

Chaque organe élastique 40 est par exemple formé par un empilement de rondelles de type Belleville, chaque rondelle s'étendant longitudinalement entre un petit contour et un second contour, les rondelles étant empilées et solidarisées entre elles de sorte que deux rondelles adjacentes ont soit leurs petits contours respectifs en contact, soit leurs grands contours respectifs en contact.Each elastic member 40 is for example formed by a stack of Belleville washers, each washer extending longitudinally between a small contour and a second contour, the washers being stacked and secured together so that two adjacent washers have either their small ones. respective contours in contact, their respective large contours in contact.

Les organes de guidage 20 décrits précédemment permettent d'assurer un contact d'au moins un élément de roulement 28 avec la piste de roulement correspondante, et cela même si la piste de roulement est irrégulière.The guide members 20 described above make it possible to ensure contact of at least one rolling element 28 with the corresponding raceway, even if the raceway is irregular.

Ainsi, les rails de guidage 18 peuvent être relativement sommaires, donc particulièrement économiques, puisque toute irrégularité de la piste de roulement est rattrapée par les organes de guidage 20.Thus, the guide rails 18 can be relatively simple, and therefore particularly economical, since any irregularity of the raceway is caught by the guide members 20.

En outre, de tels moyens de guidage 16 comprenant des éléments roulants, ils ne génèrent que peu ou pas d'efforts de frottement s'opposant au déplacement de la partie mobile 22 du mât 12.In addition, such guiding means 16 comprising rolling elements, they generate little or no friction forces opposing the displacement of the movable portion 22 of the mast 12.

Toutefois, il convient de noter que de tels moyens de guidage 16 sommaires ne permettent pas d'assurer une reprise satisfaisante des efforts appliqués sur le mât 12, dus à des contraintes extérieures.However, it should be noted that such summary guide means 16 can not ensure a satisfactory recovery of the forces applied to the mast 12, due to external constraints.

Ainsi, afin d'assurer une reprise satisfaisante des efforts appliqués sur le mât 12, lorsque cela est le plus nécessaire, la structure de mât 10 comporte des premiers moyens 42 de reprise d'efforts dans au moins une seconde direction Y perpendiculaire à la direction de hissage Z, destinés à être solidarisés à la partie structurelle 11 du véhicule sous-marin, à proximité de l'extrémité supérieure 14B du support 14, et destinés à former une butée, dans ladite seconde direction Y, pour le corps 26 de la partie mobile 22 du mât 12 lorsque cette partie mobile 22 est dans sa position déployée.Thus, in order to ensure a satisfactory recovery of the forces applied to the mast 12, when it is most necessary, the mast structure 10 comprises first means 42 for taking up forces in at least a second direction Y perpendicular to the direction of hoisting Z, intended to be secured to the structural part 11 of the underwater vehicle, near the upper end 14B of the support 14, and intended to form a stop, in said second direction Y, for the body 26 of the mobile part 22 of the mast 12 when the movable portion 22 is in its deployed position.

Plus particulièrement, les premiers moyens de reprise d'efforts 42 comportent au moins un organe de reprise d'efforts 44 solidarisé à ladite partie structurelle 11 du véhicule sous-marin, et un organe de calage complémentaire 45, porté par le corps 26 de la partie mobile 22 et destiné à coopérer avec l'organe de reprise d'efforts 44.More particularly, the first force recovery means 42 comprise at least one force-transfer member 44 secured to said structural part 11 of the underwater vehicle, and a complementary wedging member 45 carried by the body 26 of the movable part 22 and intended to cooperate with the force recovery member 44.

Chaque organe de reprise d'efforts 44 présente une première surface 44A inclinée par rapport à la direction verticale, de manière à former une surface de butée s'opposant au déplacement de la partie mobile 22 au-delà de sa position déployée. Ainsi, l'organe de calage 45 complémentaire présente une seconde surface 45A inclinée par rapport à la direction verticale, sensiblement parallèle à la première surface 44A, et destinée à coopérer avec la première surface 44A lorsque la partie mobile 22 est dans sa position déployée.Each force recovery member 44 has a first surface 44A inclined relative to the vertical direction, so as to form an abutment surface opposing the displacement of the movable portion 22 beyond its deployed position. Thus, the complementary wedging member 45 has a second surface 45A inclined relative to the vertical direction, substantially parallel to the first surface 44A, and intended to cooperate with the first surface 44A when the movable portion 22 is in its deployed position.

Ainsi, en considérant un sens d'orientation pris depuis l'extrémité inférieure du support 14 vers l'extrémité supérieure 14B de ce support 14, la première surface 44A est inclinée de manière à se rapprocher du mât dans la seconde direction Y en suivant ledit sens d'orientation.Thus, by considering a direction of orientation taken from the lower end of the support 14 towards the upper end 14B of this support 14, the first surface 44A is inclined so as to approach the mast in the second direction Y by following said direction of orientation.

Avantageusement, les moyens de reprise d'effort 42 comportent au moins deux organes de reprise d'effort 44, agencés en regard l'un de l'autre dans ladite seconde direction Y, et au moins deux organes de calage 45, chacun destiné à coopérer avec l'un des organes de reprise d'effort 44 respectif. Les premières surfaces 44A des organes de reprise d'effort 44 convergent donc l'uns vers l'autre en suivant ledit sens d'orientation.Advantageously, the force recovery means 42 comprise at least two force-absorbing members 44, arranged facing each other in said second direction Y, and at least two wedging members 45, each intended for cooperate with one of the respective force recovery members 44. The first surfaces 44A of the force-absorbing members 44 thus converge towards one another along said direction of orientation.

De préférence, les moyens de reprise d'effort 42 comportent au moins deux ensembles de deux organes de reprise d'effort 44 agencés en regard l'un de l'autre dans ladite seconde direction Y, les ensembles étant séparés par une distance prédéterminée dans la direction de hissage Z, et au moins deux ensembles de deux organes de calage 45, chaque organe de calage 45 étant destiné à coopérer avec un organe de reprise d'effort 44 respectif. Ladite distance prédéterminée est par exemple sensiblement égale à la distance entre deux organes de guidage 20 alignés dans la direction de hissage Z.Preferably, the force recovery means 42 comprise at least two sets of two force-absorbing members 44 arranged facing each other in said second direction Y, the sets being separated by a predetermined distance in the hoisting direction Z, and at least two sets of two wedging members 45, each wedge member 45 being adapted to cooperate with a respective force-taking member 44. Said predetermined distance is for example substantially equal to the distance between two guide members 20 aligned in the direction of hoisting Z.

Avantageusement, au moins l'un parmi chaque organe de reprise d'effort 44 et chaque organe de calage 45 comporte une partie en élastomère, par exemple en caoutchouc, portant ladite première 44A ou seconde 45A surface correspondante. Cette partie en élastomère permet d'amortir un choc lorsque l'organe de reprise d'effort 44 et l'organe de calage 45 viennent en contact, dans la position déployée du mât 12.Advantageously, at least one of each force-absorbing member 44 and each wedging member 45 comprises an elastomer part, for example rubber, bearing said first 44A or second 45A corresponding surface. This elastomer part makes it possible to dampen a shock when the force-taking member 44 and the wedging member 45 come into contact, in the deployed position of the mast 12.

De manière optionnelle, on peut également prévoir des moyens de reprise d'effort supplémentaires dans une troisième direction X perpendiculaire à la seconde direction Y et à la direction de hissage Z. Ces moyens de reprise d'effort supplémentaires sont dans ce cas similaires aux premiers moyens de reprise d'effort 42 décrits précédemment.Optionally, it is also possible to provide additional force-recovery means in a third direction X perpendicular to the second direction Y and the direction of hoisting Z. These additional force-recovery means are in this case similar to the first effort recovery means 42 described above.

Avantageusement, la structure de mât 10 comporte également des seconds moyens de reprise d'efforts (non représentés), destinés à être solidarisés à la partie structurelle 11 du véhicule sous-marin à proximité de l'extrémité inférieure du support, destinés à former une butée, dans au moins une direction perpendiculaire à la direction de hissage, pour le corps 26 lorsque la partie mobile 24 du mât est dans sa position affalée. En effet, la position affalée est également une position dans laquelle le mât 12 est susceptible d'être soumis à des contraintes importantes, notamment en cas de chocs militaires.Advantageously, the mast structure 10 also comprises second force recovery means (not shown), intended to be secured to the structural part 11 of the underwater vehicle near the lower end of the support, intended to form a stop, in at least one direction perpendicular to the direction of hoisting, for the body 26 when the movable portion 24 of the mast is in its lowered position. Indeed, the down position is also a position in which the mast 12 is likely to be subject to significant constraints, especially in case of military shocks.

Ces seconds moyens de reprise d'efforts sont similaires aux premiers moyens de reprise d'efforts 42, à l'exception du fait que les surfaces inclinées des organes de reprise d'effort et des organes de calage sont inversées par rapport à celles des premiers moyens de reprise d'effort 42, pour former des butées de fin de course dans la direction de hissage Z, entrant en contact lorsque le mât 12 est dans sa position affalée.These second force recovery means are similar to the first force recovery means 42, with the exception that the inclined surfaces of the force take-up members and the wedging members are reversed relative to those of the first effort recovery means 42, to form end stops in the hoisting direction Z, coming into contact when the mast 12 is in its lowered position.

On a représenté sur la figure 3 une structure de mât 10 selon un deuxième exemple de mode de réalisation de l'invention. Sur cette figure, les éléments analogues à ceux du premier mode de réalisation sont désignés par des références identiques.We have shown on the figure 3 a mast structure 10 according to a second exemplary embodiment of the invention. In this figure, elements similar to those of the first embodiment are designated by identical references.

Conformément à ce deuxième mode de réalisation, chaque rail de guidage 18 présente des première 18A et seconde 18B pistes de roulement sensiblement planes, agencées de manière à converger l'une vers l'autre depuis le montant 15 portant ce rail, en direction du mât 12, de sorte que ce rail 18 présente une section en forme de V dans tout plan perpendiculaire à la direction de hissage Z.According to this second embodiment, each guide rail 18 has first 18A and second 18B substantially planar tracks, arranged so as to converge towards one another from the upright 15 carrying this rail, towards the mast 12, so that this rail 18 has a V-shaped section in any plane perpendicular to the Z hoisting direction.

Chaque organe de guidage 20 comporte alors au moins un premier élément de roulement 28, porté par le corps 26, agencé en contact de la première piste de roulement 18A et destiné à rouler sur celle-ci dans la direction de hissage Z. Ainsi, cet élément de roulement 28 présente une partie de roulement mobile en rotation autour d'un axe A perpendiculaire à la direction de hissage, et sensiblement parallèle à la première piste de roulement 18A. Cette partie de roulement est de préférence réalisée en polyuréthane, afin de ne générer que peu de bruit lors de son roulement sur la piste de roulement 18A.Each guide member 20 then comprises at least one first rolling element 28, carried by the body 26, arranged in contact with the first rolling track 18A and intended to roll on the latter in the hoisting direction Z. Thus, this rolling element 28 has a rolling portion rotatable about an axis A perpendicular to the hoisting direction, and substantially parallel to the first rolling track 18A. This rolling part is preferably made of polyurethane, in order to generate little noise during its rolling on the track 18A.

Chaque organe de guidage 20 comporte également au moins un second élément de roulement 30, porté par le corps 26, et agencé en contact de la seconde piste de roulement 18B et destiné à rouler sur celle-ci dans la direction de hissage Z. Ainsi, cet élément de roulement 30 comporte également une partie de roulement mobile en rotation autour d'un axe perpendiculaire à la direction de hissage et sensiblement parallèle à la seconde piste de roulement 18A. Cette partie de roulement est de préférence réalisée en polyuréthane, afin de ne générer que peu de bruit lors de son roulement sur la piste de roulement 18B.Each guide member 20 also comprises at least one second rolling element 30, carried by the body 26, and arranged in contact with the second rolling track 18B and intended to roll on it in the hoisting direction Z. Thus, this rolling element 30 also comprises a rolling portion rotatable about an axis perpendicular to the hoisting direction and substantially parallel to the second raceway 18A. This rolling part is preferably made of polyurethane, so as to generate little noise during its rolling on the track 18B.

Plus particulièrement, chaque organe de guidage 20 comporte avantageusement deux premiers éléments de roulement 28, et un premier élément de support 32, comme cela est représenté sur la figure 3. Chaque premier élément de roulement 28 est relié au premier élément de support 32 par une liaison pivot 34 respective autour dudit axe de rotation A.More particularly, each guide member 20 advantageously comprises two first rolling elements 28, and a first support element 32, as shown in FIG. figure 3 . Each first rolling element 28 is connected to the first support element 32 by a respective pivot connection 34 about said axis of rotation A.

En outre, le premier élément de support 32 est relié au corps 26 par une liaison pivot 36 autour d'un axe sensiblement parallèle aux axes de rotation A des premiers éléments de roulement.In addition, the first support member 32 is connected to the body 26 by a pivot connection 36 about an axis substantially parallel to the axes of rotation A of the first rolling elements.

De la même manière, chaque organe de guidage 20 comporte deux seconds éléments de roulement 30, et un second élément de support (non représenté), chaque second élément de roulement 30 étant relié au second élément de support par une liaison pivot respective, et ledit second élément de support étant relié au corps par une liaison pivot.Similarly, each guide member 20 has two second rolling members 30, and a second support member (not shown), each second rolling member 30 being connected to the second support member by a respective pivot link, and second support member being connected to the body by a pivot connection.

Avantageusement, chaque organe de guidage 20 comporte, pour chacun des premier 32 et second éléments de support, des moyens élastiques 38 de stabilisation, à effet de compression, s'étendant entre cet élément de support 32 et un organe d'appui (non représenté) porté par le corps 26, de manière à appliquer un effort de pression sur les éléments de roulement portés par cet élément de support, contre la piste de roulement correspondante.Advantageously, each guide member 20 comprises, for each of the first 32 and second support members, elastic means 38 of stabilization, compression effect, extending between this support member 32 and a support member (not shown ) carried by the body 26, so as to apply a pressure force on the rolling elements carried by the support member, against the corresponding raceway.

On notera que l'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pourrait présenter diverses variantes sans sortir du cadre des revendications.Note that the invention is not limited to the embodiment described above, but could have various variants without departing from the scope of the claims.

En particulier, on pourrait prévoir d'autres moyens de guidage que ceux décrits ci-dessus. In particular, it could provide other guiding means than those described above.
