Description

Domaine technique de l'inventionTechnical field of the invention

Un premier aspect de l'invention est relatif à un dispositif de support pour câble-porteur d'une installation de téléphérique, comprenant une pièce de soutien recevant une portion de câble-porteur et reposant sur un sabot de l'installation.A first aspect of the invention relates to a support device for a cable-carrier of a cable car installation, comprising a support piece receiving a portion of cable-carrier and resting on a shoe of the installation.

Un deuxième aspect de l'invention porte sur un procédé de contrôle d'un câble-porteur en appui sur un dispositif de support selon le premier aspect.A second aspect of the invention relates to a method of controlling a carrier cable resting on a support device according to the first aspect.

État de la techniqueState of the art

Dans une installation de téléphérique, les cabines se déplacent le long de lignes comprenant chacune d'une part au moins un câble-porteur tendu de manière fixe entre les stations pour la reprise des efforts de gravité des cabines et d'autre part au moins un câble-tracteur défilant et auxquelles les cabines sont accrochées par des moyens de liaison fixes pour transmettre les efforts nécessaires au déplacement des cabines. Chaque câble-porteur repose sur des sabots de l'installation pour assurer la reprise des efforts. À chaque sabot, une portion de câble-porteur est placée dans une pièce de soutien, généralement munie d'une garniture de maintien latéral du câble-porteur, laquelle pièce de soutien repose sur le sabot proprement dit. Pour limiter les risques d'endommagement du câble-porteur, notamment par cisaillement, chaque pièce de soutien présente une courbure dans la direction du câble-porteur. La valeur du rayon de courbure le long de la pièce de soutien peut éventuellement être variable suivant les applications.In a cable car installation, the cabins move along lines each comprising on the one hand at least one carrier cable tensioned in a fixed manner between the stations for the recovery of the gravity forces of the cabins and on the other hand at least one moving cable-tractor and to which the cabins are hung by fixed connection means to transmit the forces required to move the cabins. Each carrier cable rests on hooves of the installation to ensure the recovery of efforts. At each shoe, a portion of cable-carrier is placed in a support part, usually provided with a lateral support lining of the cable-carrier, which support part rests on the shoe itself. To limit the risk of damage to the carrier cable, in particular by shearing, each support piece has a curvature in the direction of the cable-carrier. The value of the radius of curvature along the support piece may possibly be variable according to the applications.

Malgré un montage fixe, les règlements administratifs imposent un contrôle périodique de l'ensemble des câbles-porteurs, en particulier sur les portions reçues par les pièces de soutien. Le contrôle en dehors desdites portions se pratique visuellement sans souci d'accès. Par contre, le contrôle des portions reposant dans les pièces de soutien solidaires des sabots représente un problème compte tenu de l'impossibilité d'accès à la zone de contact.Despite a fixed set-up, the by-laws require periodic inspection of all load-bearing cables, particularly on the portions received by the support pieces. Control outside said portions is practiced visually without concern for access. On the other hand, the control of the portions resting in the support parts of the hooves is a problem in view of the impossibility of access to the contact zone.

Une technique connue consiste à ménager aux extrémités de chaque câble-porteur une réserve de longueur de câble-porteur. Pour le contrôle de la zone d'appui d'un câble-porteur sur une pièce de soutien solidaire d'un sabot, il suffit d'utiliser la réserve de câble-porteur pour le translater jusqu'à une position de la zone d'appui décalée de la pièce de soutien. Mais une telle pratique nécessite la présence d'au moins une réserve de câble-porteur, susceptible d'être gênante, onéreuse, voire quelquefois impossible à aménager.One known technique is to provide at the ends of each carrier cable a length reserve cable-carrier. For the control of the support zone of a carrier cable on a support piece integral with a shoe, it is sufficient to use the cable-carrier reserve to translate it to a position of the shoe area. offset support of the support piece. But such a practice requires the presence of at least one cable-carrier reserve, which can be annoying, expensive, or sometimes impossible to develop.

Une autre technique consiste à soulever la portion de câble-porteur en appui sur la pièce de soutien, grâce à un système de levage adapté. Mais une telle pratique n'est réalisable qu'aux emplacements où le rayon de courbure de la pièce de soutien, et donc celui du câble-porteur, est supérieur à une valeur minimale en dessous de laquelle le soulèvement du câble-porteur nécessiterait des efforts trop élevés et risquerait de provoquer un endommagement local.Another technique is to lift the portion of cable-carrier resting on the support part, thanks to a suitable lifting system. But such a practice is feasible only at locations where the radius of curvature of the support part, and therefore that of the carrier cable, is greater than a minimum value below which the lifting of the cable-carrier would require efforts. too high and may cause local damage.

Le document GB571948 décrit un dispositif de support pour câble-porteur comprenant une pièce de soutien recevant une portion de câble-porteur et subdivisée, dans la direction du câble-porteur, en une pluralité de tronçons élémentaires. Les tronçons élémentaires centraux reposent sur des galets rotatifs solidaires du sabot. Le coefficient de frottement entre le câble et les tronçons élémentaires est supérieur au coefficient de frottement entre les tronçons élémentaires et les galets rotatifs. Le passage d'une masse le long du câble porteur induit une variation angulaire du sabot, et il en résulte un mouvement de rotation des galets, de sorte que le câble ne subit pas d'usure en raison de sa liaison avec le sabot.The document GB571948 discloses a support device for a carrier cable comprising a support part receiving a portion of the carrier cable and subdivided, in the direction of the carrier cable, into a plurality of elementary sections. The central elementary sections are based on pebbles rotary integral with the hoof. The coefficient of friction between the cable and the elementary sections is greater than the coefficient of friction between the elementary sections and the rotary rollers. The passage of a mass along the carrier cable induces an angular variation of the shoe, and this results in a rotational movement of the rollers, so that the cable does not undergo wear due to its connection with the shoe.

Objet de l'inventionObject of the invention

Un objet de l'invention consiste à réaliser un dispositif de support permettant un contrôle visuel aux emplacements où le rayon de courbure du câble-porteur est sensiblement petit, et cela sans nécessiter d'aménager de réserve de longueur de câble-porteur.An object of the invention is to provide a support device for a visual control at locations where the radius of curvature of the carrier cable is substantially small, and without the need to arrange spare length of cable-carrier.

Le dispositif selon l'invention est remarquable en ce que la pièce de soutien est subdivisée, dans la direction du câble-porteur, en une pluralité de tronçons élémentaires reposant chacun sur au moins une cale intermédiaire amovible en contact avec le sabot, pour pouvoir éloigner chaque tronçon élémentaire par rapport au câble-porteur après le retrait de la cale.The device according to the invention is remarkable in that the support piece is subdivided, in the direction of the carrier cable, into a plurality of elementary sections each resting on at least one removable intermediate wedge in contact with the shoe, to be able to move away. each elementary section relative to the carrier cable after removal of the hold.

Ladite au moins une cale intermédiaire intercalée entre le sabot et le tronçon élémentaire associé est avantageusement montée de manière amovible. Le retrait de la cale autorise dans un premier temps l'abaissement du tronçon élémentaire en direction du sabot pour l'éloigner du câble-porteur, puis dans un deuxième temps le retrait du tronçon élémentaire, le rendant amovible sélectivement. Le câble-porteur reste alors en appui sur le dispositif de support au niveau des tronçons élémentaires encore en place et le contrôle visuel du câble-porteur sur la longueur en contact avec le tronçon élémentaire avant le retrait de la cale devient possible. Pour un contrôle complet du câble-porteur sur toute la longueur du dispositif de support, il suffit de répéter cette opération pour l'ensemble des tronçons élémentaires.Said at least one intermediate shim interposed between the shoe and the associated elementary section is advantageously removably mounted. The withdrawal of the wedge initially allows the lowering of the elementary section in the direction of the shoe to move away from the carrier cable, and then in a second step the withdrawal of the elementary section, making it selectively removable. The carrier cable then remains supported on the support device at the level of the elementary sections still in place and the visual control of the carrier cable along the length in contact with the elementary section before removal of the wedge becomes possible. For complete control of the carrier cable over the entire length of the support device, it suffices to repeat this operation for all the elementary sections.

Selon un mode de réalisation préférentiel, chaque tronçon élémentaire comporte des moyens d'accouplement à un organe complémentaire d'un système de levage dudit tronçon élémentaire. Grâce à de tels moyens d'accouplement, le retrait de la cale est possible après une élévation du tronçon élémentaire par le système de levage pour libérer la cale.According to a preferred embodiment, each elementary section comprises means for coupling to a complementary member of a lifting system of said elementary section. With such coupling means, removal of the wedge is possible after an elevation of the elementary section by the lifting system to release the wedge.

D'autres caractéristiques techniques peuvent être utilisées isolément ou en combinaison :

  • chaque tronçon élémentaire est solidarisé au sabot par au moins une vis de fixation assurant une mise en compression de la cale correspondante,
  • les moyens d'accouplement sont constitués par au moins une échancrure débouchant sur un bord longitudinal du tronçon élémentaire,
  • chaque tronçon élémentaire est équipé, sur toute sa longueur dans la direction du câble-porteur, d'une garniture de maintien latéral du câble-porteur perpendiculairement à ladite direction, la garniture étant logée dans une rainure complémentaire.
Other technical characteristics can be used in isolation or in combination:
  • each elementary section is secured to the shoe by at least one fastening screw ensuring compression of the corresponding shim,
  • the coupling means consist of at least one notch opening on a longitudinal edge of the elementary section,
  • each elementary section is equipped, over its entire length in the direction of the carrier cable, with a lateral holding lining of the carrier cable perpendicular to said direction, the lining being housed in a complementary groove.

Comme évoqué ci-dessus, le procédé de contrôle selon le deuxième aspect de l'invention est tel que pour chaque tronçon élémentaire, on réalise les étapes successives suivantes :

  • on accouple le tronçon élémentaire à un organe complémentaire d'un système de levage,
  • on actionne le système de levage vers une position d'élévation du tronçon élémentaire pour libérer la cale disposée au préalable sous le tronçon élémentaire,
  • on retire la cale,
  • on actionne le système de levage vers une position d'abaissement du tronçon élémentaire pour éloigner le tronçon élémentaire par rapport au câble-porteur,
  • on sépare le tronçon élémentaire et le système de levage,
  • on retire le tronçon élémentaire,
  • on contrôle le câble-porteur sur la longueur libérée.
As mentioned above, the control method according to the second aspect of the invention is such that for each elementary section, the following successive steps are carried out:
  • the elementary section is coupled to an element complementary to a lifting system,
  • the lifting system is actuated to an elevation position of the elementary section to release the shim previously arranged under the elementary section,
  • remove the hold,
  • the lifting system is actuated to a lowering position of the elementary section to move the elementary section away from the carrying cable,
  • separating the elementary section and the lifting system,
  • we remove the elementary section,
  • the carrier cable is controlled over the released length.

Description d'un mode préférentiel de l'inventionDescription of a preferred embodiment of the invention

Sur les figures 1 à 3, un dispositif de support pour un câble-porteur 10 d'une installation de téléphérique comprend une pièce de soutien 11 recevant une portion de câble-porteur 10 proche de son extrémité. La pièce de soutien 11 repose sur un sabot 12 de l'installation pour reprendre les efforts appliqués par la portion de câble-porteur 10 en appui sur la pièce de soutien 11 et les transmettre jusqu'au sol.On the Figures 1 to 3 a support device for a carrying cable 10 of a cable car installation comprises a support piece 11 receiving a portion of the cable-carrier 10 close to its end. The support piece 11 rests on a shoe 12 of the installation to take up the forces applied by the cable-carrying portion 10 resting on the support part 11 and transmit them to the ground.

Conformément au premier aspect de l'invention, la pièce de soutien 11 est subdivisée, dans la direction du câble-porteur 10, en une pluralité de tronçons élémentaires 13a, 13b,...,13i, ...,13n. Chaque tronçon élémentaire 13i repose sur au moins une cale intermédiaire 14 en contact avec le sabot 12. Chaque cale 14 est donc interposée entre le tronçon élémentaire 13i associé et le sabot 12. Dans l'exemple particulier illustré, trois cales intermédiaires 14 sont associées à chaque tronçon élémentaire 13i en étant échelonnées le long du tronçon élémentaire 13i dans la direction du câble-porteur 10. Chaque cale intermédiaire 14 est directement rapportée sur le sabot 12 sans aucun moyen de fixation prévu entre ces deux pièces. D'une manière identique, chaque tronçon élémentaire 13i est directement rapporté sur les cales élémentaires 14 associées, sans utiliser de moyen de fixation vis-à-vis des cales intermédiaires 14.According to the first aspect of the invention, the support part 11 is split in the direction of the supporting cable 10, into a plurality of elementary sections 13 a, 13 b, ..., 13 i, ..., 13 n . Each elementary section 13 i rests on at least one intermediate shim 14 in contact with the shoe 12. Each shim 14 is thus interposed between the elementary section 13 i associated with the shoe 12. In the particular example illustrated, three intermediate shims 14 are associated with each elementary section 13 i being staggered along the elementary section 13 i in the direction of the carrier cable 10. Each intermediate shim 14 is directly attached to the shoe 12 without any fastening means provided between these two parts. In an identical manner, each elementary section 13 i is directly attached to the associated elementary shims 14, without using means of attachment with respect to intermediate shims 14.

Chaque tronçon élémentaire 13i est solidarisé, par contre, directement au sabot 12 par l'intermédiaire d'au moins une vis de fixation 15 assurant une mise en compression des cales intermédiaires 14 correspondantes. Chaque vis de fixation 15 se compose d'une tête d'appui 16 et d'un corps allongé 17 subdivisé en un premier tronçon lisse du côté de la tête d'appui 16 et en un deuxième tronçon fileté du côté opposé à la tête d'appui 16. L'organisation est telle que la tête d'appui 16 vient en contact par le dessus avec le tronçon élémentaire 13i, et que le deuxième tronçon fileté vient se visser dans un orifice taraudé prévu dans la face supérieure du sabot 12 en traversant un passage prévu dans l'épaisseur du tronçon élémentaire 13i. Quatre vis de fixation 15 sont disposées deux à deux de part et d'autre latéralement par rapport à la portion de câble-porteur 10 reçue. De chaque côté, les deux vis de fixation 15 sont décalées dans la direction du câble-porteur 10.Each elementary section 13 i is secured, on the other hand, directly to the shoe 12 by means of at least one fixing screw 15 ensuring a compression of the intermediate shims 14 corresponding. Each fastening screw 15 consists of a bearing head 16 and an elongated body 17 subdivided into a first smooth section on the side of the bearing head 16 and a second threaded section on the opposite side to the head of the head. 16. The organization is such that the support head 16 comes into contact from above with the elementary section 13 i , and that the second threaded portion is screwed into a threaded orifice provided in the upper face of the shoe 12 crossing a passage provided in the thickness of the elementary section 13 i . Four fixing screws 15 are arranged in pairs on either side laterally relative to the cable-carrier portion 10 received. On each side, the two fixing screws 15 are offset in the direction of the carrying cable 10.

La configuration relative décrite ci-dessus entre la pièce de soutien 11 (composée par la réunion des tronçons élémentaires 13i), le sabot 12 et les cales intermédiaires 14 permet, après le démontage des vis de fixation 15 associées à un tronçon élémentaire 13i et le soulèvement dudit tronçon 13i, de retirer les cales intermédiaires 14 disposées au préalable sous le tronçon élémentaire 13i. Une telle possibilité confère à chaque cale intermédiaire 14 un caractère amovible sans aucun démontage. Le retrait de l'ensemble des cales intermédiaires 14 associées à un tronçon élémentaire 13i donné autorise ultérieurement ledit tronçon élémentaire 13i à pouvoir être abaissé en direction du sabot 12 pour s'éloigner par rapport au câble-porteur 10, puis à être retiré. Il en résulte que les tronçons élémentaires 13i sont amovibles sélectivement, indépendamment les uns des autres, notamment indépendamment des deux tronçons adjacents 13i-1 et 13i+1. Le caractère amovible de chaque tronçon élémentaire 13i permet de générer un espace libre sous le câble-porteur 10 à l'emplacement dudit tronçon 13i par retrait de ce dernier. L'espace libre généré sous le câble-porteur 10 sur une longueur égale à la longueur du tronçon élémentaire 13i retiré permet un contrôle visuel du câble-porteur 10 sur cette longueur.The relative configuration described above between the support piece 11 (composed by the union of the elementary sections 13 i ), the shoe 12 and the intermediate wedges 14 makes it possible, after the dismounting of the fixing screws 15 associated with an elementary section 13 i and lifting said section 13 i , to remove the intermediate shims 14 previously arranged under the elementary section 13 i . Such a possibility gives each intermediate shim 14 a removable character without any disassembly. The withdrawal of all Intermediate shims 14 associated with a given elementary section 13 i later allow said elementary section 13 i to be able to be lowered in the direction of the shoe 12 so as to move away from the carrying cable 10 and then be removed. As a result, the elementary sections 13 i are selectively removable, independently of each other, in particular independently of the two adjacent sections 13 i-1 and 13 i + 1 . The removable nature of each elementary section 13 i makes it possible to generate a free space under the carrying cable 10 at the location of said section 13 i by removing the latter. The free space generated under the carrying cable 10 over a length equal to the length of the elementary section 13 i removed allows a visual check of the carrier cable 10 over this length.

En vue de l'utilisation décrite ci-dessus de la pièce de soutien 11, chaque tronçon élémentaire 13i comporte des moyens d'accouplement à un organe complémentaire d'un système de levage (non représenté en entier) dudit tronçon élémentaire 13i. À titre d'exemple, les moyens d'accouplement sont constitués par au moins une échancrure 18 débouchant sur un bord longitudinal du tronçon élémentaire 13i. Le bord longitudinal correspond à un bord orienté dans la direction du câble-porteur 10. Dans la variante illustrée, le tronçon intermédiaire 13i comporte quatre échancrures 18 réparties deux à deux sur les deux bords longitudinaux du tronçon élémentaire 13i.With a view to the use described above of the support part 11, each elementary section 13 i comprises means for coupling to a complementary member of a lifting system (not shown in full) of said elementary section 13 i . By way of example, the coupling means consist of at least one notch 18 opening on a longitudinal edge of the elementary section 13 i . The longitudinal edge corresponds to an edge oriented in the direction of the carrier cable 10. In the variant illustrated, the intermediate section 13 i comprises four notches 18 distributed in pairs on the two longitudinal edges of the elementary section 13 i .

En référence à la figure 2, le système de levage utilisé pour l'élévation et l'abaissement successifs des tronçons élémentaires 13i peut mettre en oeuvre au moins un vérin, par exemple de type hydraulique, comprenant chacun un corps 19 et une tige coulissante 20 associée à un piston monté mobile dans le corps 19. À titre d'exemple, le système de levage comporte quatre vérins indépendants. Toujours dans une variante possible en aucun cas limitative, l'organe complémentaire aux moyens d'accouplement formés par les échancrures 18 est constitué par une collerette radiale 21 disposée en saillie de chaque corps 19 pour venir par le dessous au contact du tronçon élémentaire 13i après la mise en place latéralement des corps 19 dans les échancrures 18. Dans ce cas, les tiges coulissantes 20 sont destinées à venir prendre appui par leur extrémité libre sur le sabot 12 (voir figure 2). Dans une variante non représentée, les collerettes radiales 21 peuvent être prévues en saillie des tiges coulissantes 20 tandis que les corps 19 sont destinés à venir prendre appui sur le sabot 12 pendant le mouvement relatif des tiges 20 par rapport aux corps 19.With reference to the figure 2 , the lifting system used for the successive raising and lowering of the elementary sections 13 i can implement at least one jack, for example of the hydraulic type, each comprising a body 19 and a sliding rod 20 associated with a mounted piston In the example, the lifting system has four independent cylinders. Still in a possible variant that is in no way limitative, the member complementary to the coupling means formed by the notches 18 is constituted by a radial collar 21 arranged projecting from each body 19 to come from below in contact with the elementary section 13 i after the laterally placing of the bodies 19 in the notches 18. In this case, the sliding rods 20 are intended to be supported by their free end on the shoe 12 (see figure 2 ). In a variant not shown, the radial flanges 21 may be provided in projecting sliding rods 20 while the bodies 19 are intended to bear on the shoe 12 during the relative movement of the rods 20 relative to the body 19.

Chaque tronçon élémentaire 13i est équipé, sur toute sa longueur prise dans la direction du câble-porteur 10, d'une garniture de maintien latéral 22 du câble-porteur 10. La notion de « latéral » correspond à une direction perpendiculaire à la direction du câble-porteur 10. La garniture 22 est logée dans une rainure complémentaire 23. La fixation de la garniture de maintien latéral 22 à l'intérieur de la rainure complémentaire 23 est réalisée par une pluralité de vis auxiliaires de fixation 24 réparties le long du tronçon élémentaire 13i dans la direction du câble-porteur 10 et chacune engagée dans un taraudage 25 débouchant sur le fond de la rainure 23.Each elementary section 13 i is equipped, over its entire length taken in the direction of the carrying cable 10, with a lateral holding pad 22 of the carrying cable 10. The notion of "lateral" corresponds to a direction perpendicular to the direction The liner 22 is housed in a complementary groove 23. The attachment of the lateral liner 22 within the complementary groove 23 is formed by a plurality of auxiliary fastening screws 24 distributed along the elementary section 13 i in the direction of the carrier cable 10 and each engaged in a tapping 25 opening on the bottom of the groove 23.

La forme extérieure de la garniture 22 est un cylindre droit. Par définition mathématique, un cylindre est une surface de l'espace définie par une droite génératrice passant par un point variable décrivant une courbe plane fermée (appelée courbe directrice) et gardant une direction fixe. Dans le cas d'un cylindre droit, la direction de la droite génératrice est perpendiculaire au plan de la courbe directrice. En application à la garniture 22, la courbe directrice correspond donc à une section latérale de la garniture et la direction de la droite génératrice est parallèle à la direction du câble-porteur 10.The outer shape of the liner 22 is a straight cylinder. By mathematical definition, a cylinder is a surface of the space defined by a generating line passing through a variable point describing a closed plane curve (called the guiding curve) and keeping a fixed direction. In the case of a straight cylinder, the direction of the generating line is perpendicular to the plane of the guide curve. In application to the lining 22, the guide curve thus corresponds to a lateral section of the lining and the direction of the generating line is parallel to the direction of the carrying cable 10.

Pour assurer sa fonction de maintien latéral du câble-porteur 10, la face supérieure de la section de la garniture 22, étant définie comme la face opposée à la rainure complémentaire 23, comporte au centre, dans la direction latérale, une gorge de positionnement 26 du câble-porteur 10. À titre d'exemple, la matière utilisée pour la garniture de maintien latéral 22 est du polyéthylène à haute densité.To ensure its lateral holding function of the carrier cable 10, the upper face of the section of the seal 22, being defined as the face opposite to the complementary groove 23, has in the center, in the lateral direction, a positioning groove 26 of the carrying cable 10. To For example, the material used for the side-hold liner 22 is high-density polyethylene.

La rainure complémentaire 23 prévue dans le tronçon intermédiaire 13i pour la fixation de la garniture 22 dont il est pourvu est incurvée du côté du sabot 12. Par exemple, la rainure 23 est une portion de surface de révolution ayant une génératrice constituée par un U dont les branches sont perpendiculaires à sa base. Le rayon séparant l'axe mathématique de la surface de révolution et la génératrice en U détermine la valeur locale du rayon de courbure de la pièce de soutien 11, et donc celle du rayon de courbure du câble-porteur 10. La valeur du rayon de courbure le long de la pièce de soutien 11 peut éventuellement être variable suivant les applications.The complementary groove 23 provided in the intermediate portion 13 i for fixing the lining 22 which it is provided is curved on the side of the shoe 12. For example, the groove 23 is a portion of surface of revolution having a generator constituted by a U whose branches are perpendicular to its base. The radius separating the mathematical axis from the surface of revolution and the U-shaped generator determines the local value of the radius of curvature of the support piece 11, and therefore that of the radius of curvature of the carrying cable 10. The value of the radius of curvature along the support piece 11 may possibly be variable according to the applications.

Le procédé de contrôle selon le deuxième aspect de l'invention correspond à une utilisation idoine du dispositif de support selon le premier aspect de l'invention, de la manière suivante. Le contrôle de la portion de câble-porteur 10 reçue par la pièce de soutien 11 se pratique par un contrôle successif du câble-porteur 10 sur la longueur reçue par chacun des tronçons élémentaires 13i.The control method according to the second aspect of the invention corresponds to an appropriate use of the support device according to the first aspect of the invention, as follows. The control of the portion of the cable-carrier 10 received by the support part 11 is practiced by a successive control of the cable-carrier 10 over the length received by each of the elementary sections 13 i .

Pour chaque tronçon élémentaire 13i, à partir de la configuration normale d'exploitation (figure 4), il convient dans un premier temps de retirer l'ensemble des vis de fixation 15 associées audit tronçon 13i et d'accoupler le tronçon élémentaire 13i à un organe complémentaire d'un système de levage (figure 5). Pour réaliser cette dernière opération dans l'exemple illustré, les corps 19 des vérins sont engagés latéralement dans les échancrures 18 pour positionner les collerettes radiales 21 en appui en dessous du tronçon élémentaire 13i, sous deux ailes latérales constitutives des bords longitudinaux du tronçon élémentaire 13i. Dans une étape suivante (figure 6), le système de levage est actionné vers une position d'élévation du tronçon élémentaire 13i pour libérer les cales intermédiaires 14 disposées au préalable, c'est-à-dire avant l'élévation du tronçon 13i, sous le tronçon élémentaire 13i. Pour réaliser cette opération dans l'exemple illustré, les tiges coulissantes 20 sont actionnées vers une position de sortie pour, dans un premier temps, venir en appui par leur extrémité libre contre le sabot 12, puis dans une deuxième phase, provoquer l'élévation proprement dite grâce au mouvement relatif du corps 19 par rapport à la tige 20 lorsque cette dernière est en appui contre le sabot 12. Toujours en référence à la figure 6, les cales 14 sont ensuite retirées, par exemple latéralement. Dans une étape suivante, le système de levage est actionné vers une position d'abaissement du tronçon élémentaire 13i pour le rapprocher du sabot 12 et l'éloigner par rapport au câble-porteur 10. Dans l'exemple, il suffit de commander les tiges coulissantes 20 vers une position rentrée jusqu'à un état où les collerettes radiales 21 ne supportent plus le poids du tronçon élémentaire 13i. Le câble-porteur 10 vient alors en appui au moins sur les deux tronçons élémentaires directement adjacents encore en place sur le sabot 12. Ensuite, le tronçon élémentaire 13i et le système de levage sont séparés (figure 7). Pour réaliser cette dernière opération dans l'exemple illustré, les corps 19 des vérins sont dégagés latéralement depuis les échancrures 18. En référence à la figure 8, le tronçon élémentaire 13i est ensuite retiré pour générer un espace libre sous le câble-porteur 10 à l'emplacement dudit tronçon 13i après retrait de ce dernier. L'espace libre généré sous le câble-porteur 10 sur une longueur égale à la longueur du tronçon élémentaire 13i retiré permet un contrôle visuel du câble-porteur 10 sur cette longueur libérée. Avant de contrôler le câble-porteur 10 sur une longueur en appui sur un autre tronçon élémentaire 13i, il convient de remettre en place le tronçon élémentaire préalablement retiré en réalisant les étapes suivantes dans un ordre inverse. Pour réaliser le procédé de contrôle selon le deuxième aspect de l'invention, les étapes décrites ci-dessus an application à un tronçon élémentaire 13i particulier doivent être répétées pour l'ensemble des tronçons élémentaires 13i formant la pièce de soutien 11.For each elementary section 13 i , from the normal operating configuration ( figure 4 ), it is first necessary to remove all the fixing screws 15 associated with said section 13 i and to couple the elementary section 13 i to a member complementary to a lifting system ( figure 5 ). To perform this last operation in the illustrated example, the bodies 19 of the cylinders are engaged laterally in the notches 18 to position the radial flanges 21 bearing below the elementary section 13 i , under two lateral wings constituting the longitudinal edges of the elementary section I. In a next step ( figure 6 ), the lifting system is actuated to an elevation position of the elementary section 13 i to release the intermediate shims 14 arranged at the prior, that is to say before the elevation of the section 13 i , under the elementary section 13 i . To perform this operation in the example shown, the sliding rods 20 are actuated to an output position to, at first, abut by their free end against the shoe 12, then in a second phase, cause the elevation strictly speaking thanks to the relative movement of the body 19 relative to the rod 20 when the latter is in abutment against the shoe 12. Still with reference to the figure 6 shims 14 are then removed, for example laterally. In a next step, the lifting system is actuated to a lowering position of the elementary section 13 i to bring it closer to the shoe 12 and away from the carrier cable 10. In the example, it is sufficient to order the sliding rods 20 to a retracted position to a state where the radial collars 21 no longer support the weight of the elementary section 13 i . The carrier cable 10 then bears at least on the two directly adjacent elementary sections still in place on the shoe 12. Then, the elementary section 13 i and the lifting system are separated ( figure 7 ). To carry out this last operation in the illustrated example, the bodies 19 of the jacks are released laterally from the notches 18. With reference to FIG. figure 8 , the elementary section 13 i is then removed to generate a free space under the carrying cable 10 at the location of said section 13 i after removal of the latter. The free space generated under the carrying cable 10 over a length equal to the length of the elementary section 13 i removed allows a visual check of the carrier cable 10 on this released length. Before controlling the carrier cable 10 over a length bearing on another elementary section 13 i , it is necessary to replace the elementary section previously removed by performing the following steps in reverse order. To carry out the control method according to the second aspect of the invention, the steps described above for application to a particular elementary section 13 i must be repeated for all the elementary sections 13 i forming the support part 11.

Le nombre de tronçons élémentaires 13i pourra être variable suivant les applications, notamment en fonction de la longueur de la pièce de soutien 11 dans la direction du câble-porteur 10 et en fonction de la masse maximale pour laquelle le système de levage est dimensionné. Il est clair qu'un nombre suffisant de tronçons élémentaires 13i devrait être choisi de manière à diminuer les efforts de levage au moment de l'élévation de chacun des tronçons élémentaires 13i, afin de limiter les risques d'endommagement local du câble-porteur 10.The number of elementary sections 13 i may vary according to the applications, in particular as a function of the length of the support piece 11 in the direction of the carrying cable 10 and as a function of the maximum mass for which the lifting system is dimensioned. It is clear that a sufficient number of elementary sections 13 i should be chosen so as to reduce the lifting forces at the time of the rise of each of the elementary sections 13 i , in order to limit the risks of local damage to the cable. carrier 10.
