Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne une installation de transport par câble, notamment de type bicâble, appelés plus communément téléphérique va-et-vient, va-ou-vient, débrayable, ou de type téléporteur automoteur, l'installation comportant une ligne avec un ou plusieurs câbles porteurs sur lequel roule(nt) le(s) véhicules(s).The invention relates to a cable transport installation, particularly of bicable type, more commonly called back-and-forth, back-and-forth, disengageable, or self-propelled teleporter telehandler, the installation comprising a line with one or more carrying cables on which the vehicle (s) rolls.

Ce type d'appareil comporte des gares d'extrémité dans lesquelles le(s) câbles porteurs sont ancrés. Ils sont guidés en général sur des appuis en sortie de gare appelés « sabots ». En ligne, en fonction de la configuration du terrain et de l'installation, ces câbles porteurs sont aussi supportés et guidés sur des sabots agencés au sommet d'un ou plusieurs pylônes de ligne.This type of device has end stations in which the carrier cable (s) are anchored. They are usually guided on supports at the exit of the station called "hooves". In line, depending on the configuration of the ground and the installation, these carrying cables are also supported and guided on hooves arranged at the top of one or more line towers.

Les câbles porteurs sont statiques, mais le trajet du(des) véhicule(s) en ligne provoque des mouvements de câbles, induisant des flexions accompagnées de variations de flèches et de glissement au niveau de leurs appuis. Les passages de véhicules sur les sabots, avec des charges par galet plus ou moins importantes, créent des contraintes internes dans les câbles. Par conséquent, l'ensemble de ces appuis de câble (en ligne et en gare) sont graissés. Ceci permet un meilleur glissement des câbles porteurs sur les sabots, et une protection de leur structure interne, préservant ainsi, leur durée de vie.The carrying cables are static, but the path of the vehicle (s) in line causes movements of cables, inducing flexions accompanied by variations of arrows and sliding at their supports. The passage of vehicles on the hooves, with more or less significant loads per roller, create internal stresses in the cables. As a result, all of these cable supports (in-line and at the station) are greased. This allows a better sliding of the load-bearing cables on the hooves, and a protection of their internal structure, thus preserving their service life.

Les zones des appuis de ces câbles porteurs en entrée et en sortie de sabot, représentent des zones sensibles de fatigue et d'endommagement. Pour limiter l'usure et l'endommagement de ces câbles porteurs, provoqué par le passage répété des véhicules dans ces zones, les normes et les prescriptions des constructeurs demandent, de déplacer les câbles porteurs périodiquement sur leurs appuis. La périodicité d'inspection des câbles porteurs sur des sabots de gare ou ligne peut aller de 6 ans à 12 ans, suivant le type d'appareil. Pour des câbles porteurs très sollicités, cette périodicité peut être réduite.The support zones of these carrier cables in and out of shoe, represent sensitive areas of fatigue and damage. To limit the wear and damage of these carrying cables, caused by the passage Repeated vehicles in these areas, the standards and requirements of the manufacturers ask, to move the carrier cables periodically on their supports. The periodicity of inspection of the carrying cables on station or line shoes can range from 6 years to 12 years, depending on the type of device. For heavily stressed load-bearing cables, this periodicity can be reduced.

Il est connu que le repositionnement des câbles porteurs sur les sabots d'appui, s'effectue par glissement longitudinal en tirant sur le câble depuis une réserve de câble, laquelle est située dans l'une des gares d'extrémités. La longueur de repositionnement doit être au moins égale à celle de la zone de contact du câble porteur sur l'appui, augmentée d'une longueur de sécurité. La réserve de câble est généralement formée par un tambour rotatif sur lequel sont enroulés quelques tours de câble. L'ensemble de la réserve doit résister à la tension mécanique du câble porteur, et nécessite une structure de support solidement ancrée au sol de la gare.It is known that the repositioning of the support cables on the support shoes is made by longitudinal sliding by pulling the cable from a cable pool, which is located in one of the end stations. The repositioning length must be at least equal to that of the contact zone of the support cable on the support, increased by a safety length. The cable pool is generally formed by a rotating drum on which are wound a few turns of cable. The entire reserve must withstand the mechanical tension of the carrier cable, and requires a support structure firmly anchored to the floor of the station.

On peut citer, par exemple, la demande de brevet français FR2935945 , qui divulgue une installation de téléphérique comportant un tambour d'ancrage pour fixer un câble porteur dans une station.We can cite, for example, the French patent application FR2935945 , which discloses a cable car installation comprising an anchor drum for securing a carrier cable in a station.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser une installation à téléporteur roulant sur au moins un câble porteur aérien, dont le repositionnement sur les sabots de gares et de lignes ne nécessite pas de réserve de câble dans les gares d'extrémités.The object of the invention is to provide a teleporter system rolling on at least one overhead cable, whose repositioning on the station and station hooves does not require a cable reserve in the end stations.

L'installation selon l'invention, comporte :

  • au moins un câble porteur sur lequel roule le véhicule le long de la ligne entre deux gares d'extrémités,
  • des sabots d'appui prévus dans les gares d'extrémités pour le support et le guidage du câble porteur,
  • et des moyens de repositionnement du câble porteur pour renouveler périodiquement la surface directement en contact avec les sabots d'appui, caractérisée en ce que les moyens de repositionnement du câble porteur sont configurés pour faire tourner ledit câble sur lui-même en modifiant angulairement la zone de contact en fonction du profil de la gorge de logement des sabots d'appui.
The installation according to the invention comprises:
  • at least one carrier cable on which the vehicle rolls along the line between two end stations,
  • support shoes provided in the end stations for supporting and guiding the carrying cable,
  • and means for repositioning the carrier cable to periodically renew the surface directly in contact with the support shoes, characterized in that the means for repositioning the carrier cable are configured to rotate said cable on itself by angularly changing the area contact depending on the profile of the housing groove of the support shoes.

De préférence, l'angle de rotation pour le repositionnement du câble porteur est compris entre 90° et 180°.Preferably, the angle of rotation for repositioning the carrier cable is between 90 ° and 180 °.

Selon une caractéristique de l'invention, le câble porteur est un câble clos de section circulaire, faisant partiellement saillie de la gorge de logement, et prenant appui sur une zone de contact en arc de cercle de chaque sabot d'appui.According to a characteristic of the invention, the carrier cable is a closed cable of circular section, partially projecting from the housing groove, and bearing on an arcuate contact area of each support shoe.

Selon un mode de réalisation préférentiel, le repositionnement du câble porteur est opéré au moyen d'un dispositif d'actionnement hydraulique ou mécanique, ou électromécanique, lequel est agencé dans les gares d'extrémités pour produire le couple nécessaire à la rotation partielle du câble.According to a preferred embodiment, the repositioning of the carrier cable is operated by means of a hydraulic or mechanical actuation device, or electromechanical, which is arranged in the end stations to produce the torque necessary for the partial rotation of the cable. .

Le dispositif d'actionnement comporte un système de mordaches ou autre moyens de coincement pour le serrage du câble porteur, ledit système étant fixé sur une roue dentée engrenant avec un pignon commandé par un mécanisme. Le câble porteur traverse le système de mordaches, et est relié à un ancrage , lequel est configuré pour être libre en rotation sur lui-même pendant l'opération de repositionnement angulaire.The actuating device comprises a system of jaws or other jamming means for clamping the carrier cable, said system being fixed on a gear meshing with a pinion controlled by a mechanism. The carrier cable passes through the jaws system, and is connected to an anchor, which is configured to be free to rotate on itself during the angular repositioning operation.

L'invention concerne également le procédé de repositionnement du câble consistant à :

  • maintenir le câble porteur sous tension lors du repositionnement,
  • faire tourner chaque extrémité dudit câble porteur sur son axe selon un angle compris entre 90° et 180° pour renouveler la zone de contact avec la gorge de logement des sabots d'appui et de guidage,
  • et contrôler le déplacement angulaire dudit câble dans chaque gare d'extrémité.
The invention also relates to the method of repositioning the cable consisting of:
  • hold the carrier cable under tension when repositioning,
  • rotating each end of said carrier cable on its axis at an angle of between 90 ° and 180 ° to renew the contact zone with the housing groove of the support and guiding shoes,
  • and controlling the angular displacement of said cable in each end station.

L'invention s'applique à tout type de téléphériques bicâbles porteur(s) et tracteur(s), par exemple 2S ou 3S, ou à système automoteur, nécessitant le repositionnement du(des) câble(s) porteur(s) sur les sabots à des intervalles prédéterminés en fonction du nombre de passages de véhicules.The invention applies to any type of bicable carrier cable (s) and tractor (s), for example 2S or 3S, or self-propelled, requiring the repositioning of (the) cable (s) carrier (s) on the clogs at predetermined intervals according to the number of vehicle passes.

Description d'un mode particulier de réalisationDescription of a particular embodiment

En référence à la figure 1, une installation 10 de transport par câble aérien de type téléporteur ou téléphérique va-et-vient, va-ou-vient, débrayable, comporte au moins un câble porteur 11 statique s'étendant le long de la ligne entre deux gares d'extrémités 12, 13, et un câble tracteur 14 accouplé aux véhicules 15 pour leur déplacement le long de la ligne de transport.With reference to the figure 1 , a conveyor-type telegraph or shuttle-type aerial transport installation 10, which can be disengageable, comprises at least one static carrying cable 11 extending along the line between two end stations. 12, 13, and a traction cable 14 coupled to the vehicles 15 for their movement along the transport line.

Le câble porteur 11 est solidarisé par ses deux extrémités à des ancrages 16, 17 fixés dans les gares d'extrémités 12, 13. Il est mis sous tension mécanique, et ancré de manière à rester tendu lorsque les galets du chariot 20 des véhicules 15 roulent sur lui le long de la ligne.The carrying cable 11 is secured by its two ends to anchors 16, 17 fixed in the end stations 12, 13. It is put under mechanical tension, and anchored so as to remain taut when the rollers of the carriage 20 of the vehicles 15 roll on him along the line.

Le guidage et le support du câble porteur 11 s'effectuent au moyen de sabots d'appui 18 prévus à la sortie ou à l'entrée des gares d'extrémités 12, 13, et au sommet d'un ou de plusieurs pylônes 19 de ligne.The guidance and support of the carrying cable 11 is effected by means of support shoes 18 provided at the exit or at the entrance of the end stations 12, 13, and at the top of one or more pylons 19 of line.

Le câble tracteur 14 des véhicules 15 est représenté en traits pointillés. Il longe le câble porteur 11 avec un certain décalage, et fait partie d'une boucle d'entraînement avec une poulie motrice et une poulie de renvoi (non représentées). Le câble tracteur 14 est maintenu en tension, par exemple par un contrepoids ou des vérins hydrauliques.The towing cable 14 of the vehicles 15 is shown in broken lines. It runs along the carrying cable 11 with a certain offset, and is part of a drive loop with a driving pulley and a pulley (no shown). The traction cable 14 is held in tension, for example by a counterweight or hydraulic cylinders.

Dans le cas d'une variante de téléporteur faisant usage d'un système automoteur d'entraînement du véhicule, le câble tracteur est supprimé, étant donné que le véhicule est autotracté de manière autonome en roulant sur le câble porteur.In the case of a teleporter variant using a self-propelled vehicle drive system, the towing cable is removed, since the vehicle is self-propelled by rolling on the carrier cable.

Des zones de flexion F peuvent apparaître en entrée et sortie des sabots d'appui 18 suite aux passages répétés des véhicules 15. Pour limiter l'usure et l'endommagement du câble porteur 11, on le déplace périodiquement en fonction du nombre de passages des véhicules, par exemple tous les 6 à 12 ans, pour modifier et renouveler la surface directement en contact et en engagement avec les sabots d'appui 18.Bending zones F may appear at the entrance and exit of the support shoes 18 following the repeated passages of the vehicles 15. To limit the wear and damage of the carrier cable 11, it is periodically displaced according to the number of passes of the vehicles, for example every 6 to 12 years, to modify and renew the surface directly in contact and in engagement with the support shoes 18.

La figure 2 montre le guidage du câble porteur 11 dans une gorge de logement 21 sensiblement semi-circulaire, située à la partie supérieure du sabot d'appui 18. Le câble porteur 11 utilisé est un câble clos, c'est à dire de section circulaire à surface extérieure lisse, sans torons apparents. Il fait saillie partiellement de la gorge de logement 21, et prend appui sur une zone de contact en arc de cercle faisant un angle A inférieur à 180°.The figure 2 shows the guide of the carrier cable 11 in a substantially semicircular housing groove 21 located at the upper part of the support shoe 18. The carrier cable 11 used is a closed cable, that is to say of circular section to surface smooth exterior, without exposed strands. It projects partially from the housing groove 21, and bears on an arcuate contact zone making an angle A less than 180 °.

Selon l'invention, l'installation de transport 10 est équipée d'un dispositif 22 d'actionnement (figures 5 et 6) pour la mise en rotation du câble porteur 11 de manière à assurer son repositionnement angulaire au niveau de la zone de contact des sabots d'appui 18. Ce repositionnement modifie de manière circulaire, la position de la zone en contact entre le câble porteur 11 clos et la gorge de logement 21 du sabot.According to the invention, the transport installation 10 is equipped with an actuating device 22 ( Figures 5 and 6 ) for the rotation of the carrier cable 11 so as to ensure its angular repositioning at the contact zone of the support shoes 18. This repositioning circularly modifies the position of the zone in contact between the carrier cable 11 closed and the housing groove 21 of the hoof.

Pour réaliser cette modification d'appui des surfaces en contact du câble porteur 11, ledit câble est tourné sur son axe X dans le sens de la flèche D (figure 3). Il en résulte un mouvement en rotation de course suffisante, afin de déplacer angulairement la zone de contact dudit câble avec le sabot 18. L'angle de rotation pourra se situer entre 90° et 180°, en fonction des profils des gorges de logement 21 des sabots 18.To make this support modification of the surfaces in contact with the carrying cable 11, said cable is rotated on its axis X in the direction of the arrow D ( figure 3 ). This results in a sufficient running rotation movement, in order to angularly move the contact zone of said cable with the shoe 18. The angle of rotation may be between 90 ° and 180 °, depending on the profiles of the housing grooves 21 hooves 18.

Avant de procéder à cette mise en rotation partielle du câble porteur 11 sur lui-même, il est possible de le soulever (flèche S) légèrement en le décalant du fond de la gorge de logement 21. Des éléments de roulement 23, notamment des rouleaux ou des aiguilles, peuvent être introduits dans l'intervalle 24 de séparation pour faciliter sa rotation (figure 4) Le repositionnement en rotation du câble porteur 11 clos, est effectué depuis les gares d'extrémités 12, 13, de manière simultanée ou pas.Before proceeding to this partial rotation of the carrier cable 11 on itself, it is possible to lift it (arrow S) slightly by shifting it from the bottom of the housing groove 21. Rolling elements 23, in particular rollers or needles, can be introduced into the separation gap 24 to facilitate its rotation ( figure 4 The repositioning in rotation of the closed carrying cable 11 is carried out from the end stations 12, 13, simultaneously or not.

Le dispositif d'actionnement 22 pour la mise en rotation pourra être agencé dans les gares 12, 13 au voisinage des sabots d'appui 18, pour faciliter la rotation du câble porteur 11, et le contrôle de l'angle de rotation. Pendant toute l'opération, le câble porteur 11 sera maintenu en tension dans les gares 12, 13 de manière à limiter ses mouvements et glissements sur les sabots d'appui 18. Les zones des sabots d'appui seront repérées par marquage du câble 11 à manipuler, afin de contrôler son déplacement angulaire dans la gorge de logement 21 de leurs sabots d'appui.The actuating device 22 for the rotation can be arranged in the stations 12, 13 in the vicinity of the support shoes 18, to facilitate the rotation of the carrier cable 11, and the control of the angle of rotation. During the entire operation, the carrier cable 11 will be maintained in tension in the stations 12, 13 so as to limit its movements and slips on the support shoes 18. The zones of the support shoes will be identified by marking the cable 11 to manipulate, to control its angular displacement in the housing groove 21 of their support shoes.

Sur les figures 5 et 6, le dispositif d'actionnement 22 est composé à titre d'exemple d'un système de mordaches 25 serrés sur le câble porteur 11, et entraînés en rotation par un mécanisme 26 hydraulique ou mécanique ou électromécanique, afin de produire le couple nécessaire. La rotation se fera de manière lente, pour éviter tout mouvement brusque et violent du câble 11.On the Figures 5 and 6 , the actuating device 22 is composed as an example of a system of jaws 25 clamped on the carrier cable 11, and rotated by a mechanism 26 hydraulic or mechanical or electromechanical, to produce the necessary torque. The rotation will be slow, to avoid abrupt and violent movement of the cable 11.

Le système de mordaches 25 est fixé sur une roue dentée 27 engrenant avec un pignon 28 du mécanisme 26. La roue dentée 27 est dotée d'un orifice 29 central pour le passage du câble porteur 11, lequel est serré par le système de mordaches 25, en se prolongeant vers l'ancrage 17.The jigging system 25 is fixed on a toothed wheel 27 meshing with a pinion 28 of the mechanism 26. The toothed wheel 27 is provided with a central orifice 29 for the passage of the carrying cable 11, which is clamped by the jaws system 25. , extending to the anchor 17.

Le système de mordaches 25 peut bien entendu être remplacé par tout autre moyen de coincement du câble 11.The jaws system 25 can of course be replaced by any other means of jamming the cable 11.

L'ancrage 17 de la figure 5 est configuré pour laisser sa rotation sur lui-même libre pendant l'opération de repositionnement angulaire où la câble 11 doit rester sous tension.Anchorage 17 of the figure 5 is configured to allow its free rotation during the angular repositioning operation where the cable 11 must remain energized.

Pour éviter tout endommagement du câble 11 porteur, le mouvement de repositionnement en rotation est opéré dans le sens compatible avec celui du pas de câblage du câble clos.To prevent damage to the carrier cable 11, the repositioning movement in rotation is operated in the direction compatible with that of the cable pitch of the closed cable.

L'invention est bien entendu aussi applicable à une installation de transport comportant deux câbles porteurs, par exemple du type 3S, c'est à dire ayant deux câbles porteurs et un câble tracteur. Dans ce cas, le procédé de repositionnement sera effectué sur chacun des deux câbles porteurs.The invention is of course also applicable to a transport installation comprising two load-bearing cables, for example of the 3S type, that is to say having two carrying cables and a towing cable. In this case, the repositioning process will be performed on each of the two carrying cables.

L'invention est également applicable à des téléporteurs équipés d'un système automoteur pour le déplacement par roulement le long du câble porteur 11. Dans ce cas, le câble tracteur 14 de la figure 1 est supprimé.The invention is also applicable to teleporters equipped with a self-propelled system for rolling movement along the carrying cable 11. In this case, the towing cable 14 of the figure 1 is deleted.

Le déplacement du véhicule le long du câble porteur 11 s'effectue ainsi soit par traction au moyen d'un câble tracteur 14 dans le cas d'un téléphérique 2S ou 3S, soit de manière autonome par un système automoteur solidaire du véhicule.The movement of the vehicle along the carrier cable 11 is thus performed either by traction by means of a towing cable 14 in the case of a 2S or 3S cable car, or autonomously by a self-propelled system secured to the vehicle.
