Description

La présente invention concerne un train de galet pour un câble d'entraînement, et une installation de remontée mécanique comprenant ce train de galet.The present invention relates to a roller train for a drive cable, and a lift installation comprising the roller train.

Les installations de remontée mécanique sont traditionnellement équipées de pylônes comprenant à leur sommet des balanciers ayant un ou plusieurs trains de galets. Ces trains de galet comprennent des galets montés mobiles en rotation et destinés à recevoir un câble d'entraînement aérien et porteur permettant d'entraîner des véhicules de remontée mécanique d'une station aval à une station amont de l'installation de remontée mécanique. Les trains de galet peuvent également équiper une gare.Ski lift facilities are traditionally equipped with pylons comprising at their summit rockers having one or more trains of pebbles. These roller trains comprise rollers rotatably mounted and intended to receive an aerial drive cable and carrier for driving downhill vehicles from a downstream station to an upstream station of the lift. Pebble trains can also equip a station.

Ces trains de galets situés en hauteur et en extérieur sont exposés aux intempéries et soumis à des températures parfois basses. En conséquence, pendant une période d'inactivité, comme par exemple la nuit, au cours de laquelle les galets sont immobiles, il arrive que ces galets deviennent bloqués à cause de la formation de givre. Pour débloquer ces galets et rendre l'installation à nouveau opérationnelle, il est alors nécessaire de recourir à une ou plusieurs équipes de maintenance qui intervient au sommet de chaque pylône pour déstructurer le givre accumulé. Ces opérations de maintenance sont coûteuses et chronophages.These roller trains located in height and outside are exposed to the weather and subject to sometimes low temperatures. Consequently, during a period of inactivity, for example at night, during which the rollers are immobile, it happens that these rollers become blocked because of the formation of frost. To unlock these rollers and make the installation operational again, it is then necessary to resort to one or more maintenance teams that intervene at the top of each pylon to deconstruct the accumulated ice. These maintenance operations are expensive and time consuming.

Aussi, la présente invention vise à pallier cet inconvénient en proposant un train de galet offrant la possibilité de prévenir la formation de givre ou permettre le cas échéant un dégivrage rapide et aisé, c'est-à-dire sans nécessiter une intervention de personnel de maintenance au sommet des pylônes.Also, the present invention aims to overcome this disadvantage by proposing a roller train with the possibility of preventing the formation of frost or allow if necessary a quick and easy defrosting, that is to say without requiring intervention of personnel of maintenance at the top of the pylons.

A cet effet, la présente invention a pour objet un train de galet destiné à recevoir un câble, le train de galet comprenant un châssis, un galet adapté pour recevoir le câble, et un arbre support reliant le galet au châssis, de sorte que le galet est mobile en rotation par rapport au châssis autour d'un axe de rotation confondu avec l'arbre support, caractérisé en ce que le train de galet comprend un dispositif de chauffage fixé contre le châssis et destiné à générer de la chaleur pour chauffer le châssis par conduction, le châssis étant configuré pour conduire à l'arbre support la chaleur générée par le dispositif de chauffage.For this purpose, the present invention relates to a roller train for receiving a cable, the roller train comprising a frame, a roller adapted to receive the cable, and a support shaft connecting the roller to the frame, so that the roller is rotatable relative to the frame about an axis of rotation coinciding with the support shaft, characterized in that the roller train comprises a heater fixed against the frame and intended to generate heat to heat the chassis by conduction, the chassis being configured to drive the support shaft heat generated by the heater.

Ainsi, le train de galet selon l'invention permet de prévenir la formation de givre ou le cas échéant de dégivrer, par chauffage direct et par conduction au plus proche du galet, le long de l'axe de rotation du galet. Ce chauffage est réalisé par le dispositif de chauffage apposé contre le châssis, donc sur une partie fixe du train de galet, ce qui permet de protéger le dispositif de chauffage de la partie mobile du train de galet.Thus, the roller train according to the invention makes it possible to prevent the formation of frost or, where appropriate, to de-ice, by direct heating and by conduction as close as possible to the roller, along the axis of rotation of the roller. This heating is performed by the heating device affixed against the frame, and thus on a fixed part of the roller train, which makes it possible to protect the heating device from the moving part of the roller train.

Selon un mode de réalisation préféré, le train de galet comprend des moyens d'isolation thermique configurés pour isoler le dispositif de chauffage de l'extérieur.According to a preferred embodiment, the roller train comprises thermal insulation means configured to isolate the heater from the outside.

Ainsi, le dispositif de chauffage est lui-même protégé de l'environnement, en particulier des intempéries ou encore du rayonnement ultraviolet du soleil. Cela rend le dispositif de chauffage particulièrement adapté à une utilisation en conditions extérieures, si bien que la durée de vie et les performances du train de galet selon ce mode de réalisation de l'invention sont améliorées.Thus, the heating device is itself protected from the environment, particularly the weather or the ultraviolet radiation of the sun. This makes the heater particularly suitable for use in outdoor conditions, so that the life and performance of the roller train according to this embodiment of the invention is improved.

Selon un mode de réalisation préféré, le dispositif de chauffage comprend un fil électriquement conducteur destiné à dégager de la chaleur par effet Joule, et des moyens d'isolation électrique configurés pour réaliser une double isolation électrique du fil électriquement conducteur.According to a preferred embodiment, the heating device comprises an electrically conductive wire intended to release heat by the Joule effect, and electrical insulation means configured to achieve double electrical insulation of the electrically conductive wire.

Cette double isolation électrique contribue à adapter le dispositif de chauffage aux conditions extérieures, et donc à améliorer la durée de vie et les performances du train de galet selon ce mode de réalisation de l'invention.This double electrical insulation contributes to adapting the heating device to the external conditions, and therefore to improving the service life and performance of the roller train according to this embodiment of the invention.

Selon un mode de réalisation préféré, le dispositif de chauffage s'étend au moins partiellement autour de l'axe de rotation du galet par rapport au châssis.According to a preferred embodiment, the heating device extends at least partially around the axis of rotation of the roller relative to the frame.

Ainsi, le dispositif de chauffage est au plus près de l'axe de rotation pour une action à la fois plus rapide et plus économique.Thus, the heating device is closer to the axis of rotation for an action both faster and more economical.

Selon un mode de réalisation préféré, l'arbre de support est fixe par rapport au châssis.According to a preferred embodiment, the support shaft is fixed relative to the chassis.

Cette caractéristique favorise la conduction de chaleur entre le châssis contre lequel est plaqué le dispositif de chauffage et l'arbre support confondu avec l'axe de rotation du galet. Le train de galet selon ce mode de réalisation offre donc un dégivrage plus efficace.This feature promotes the heat conduction between the frame against which the heating device is plated and the support shaft coincides with the axis of rotation of the roller. The roller train according to this embodiment thus provides a more efficient defrosting.

Selon un mode de réalisation préféré, le dispositif de chauffage est en contact surfacique avec le châssis.According to a preferred embodiment, the heating device is in surface contact with the frame.

Cela améliore la transmission de chaleur du dispositif de chauffage au châssis.This improves the heat transfer from the heater to the chassis.

De préférence, le dispositif de chauffage est collé au châssis.Preferably, the heater is glued to the frame.

Cela permet une pose rapide et aisée, y compris sur des trains de galet équipant des installations déjà existantes.This allows quick and easy installation, including on roller trains equipping existing facilities.

Selon un mode de réalisation préféré, le châssis comprend une plaque ayant une face interne située en regard du galet et une face externe opposée, le dispositif de chauffage étant positionné contre la face externe.According to a preferred embodiment, the frame comprises a plate having an inner face facing the roller and an opposite outer face, the heating device being positioned against the outer face.

Cette caractéristique permet de protéger le dispositif de chauffage du galet et en particulier des éventuelles projections de neige générées par le mouvement du galet, notamment au passage de la suspente d'un véhicule de remontée mécanique tracté par le câble. Ainsi, le train de galet selon ce mode de réalisation est particulièrement adapté pour une utilisation en extérieur.This characteristic makes it possible to protect the roller heating device and in particular any snow projections generated by the movement of the roller, in particular when the suspension of a lift vehicle towed by the cable passes. Thus, the roller train according to this embodiment is particularly suitable for use outdoors.

Selon un mode de réalisation préféré, le châssis comprend une deuxième plaque ayant une face interne située en regard du galet et une face externe opposée, le galet étant agencé entre les deux plaques, et le train de galet comprend un deuxième dispositif de chauffage qui est agencé contre la face externe de cette deuxième plaque.According to a preferred embodiment, the frame comprises a second plate having an inner face facing the roller and an opposite outer face, the roller being arranged between the two plates, and the roller train comprises a second heating device which is arranged against the outer face of this second plate.

Le chauffage est donc effectué de chaque côté du galet, ce qui accélère le dégivrage ou évite la formation de givre sur une partie de l'arbre support éloignée du ou des dispositifs de chauffage.The heating is therefore carried out on each side of the roller, which accelerates the defrosting or prevents the formation of frost on a portion of the support shaft remote from the heating device or devices.

Selon un mode de réalisation préféré, le ou chaque dispositif de chauffage s'étend sur une majeure partie de la superficie de la face externe correspondante.According to a preferred embodiment, the or each heating device extends over a major part of the surface of the corresponding outer face.

Cela permet un chauffage uniforme sur toute la longueur et largeur de la plaque formant châssis, afin de prévenir la formation de givre ou éliminer le givre qui pourrait se former entre la face interne du châssis et le galet.This allows uniform heating over the entire length and width of the frame plate, to prevent the formation of frost or eliminate frost that could form between the inner face of the frame and the roller.

Selon un autre aspect, l'invention a aussi pour objet une installation de remontée mécanique comprenant un train de galet ayant les caractéristiques précitées.According to another aspect, the invention also relates to a ski lift installation comprising a roller train having the aforementioned characteristics.

Cette installation a l'avantage de permettre de prévenir la formation de givre et éliminer le givre pouvant se former de façon rapide, sans nécessiter une action particulière de maintenance.This installation has the advantage of preventing the formation of frost and eliminating frost can form quickly without requiring special maintenance action.

D'autres caractéristiques et avantages de la présente invention ressortiront clairement de la description détaillée ci-après d'un mode de réalisation, donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :

Other features and advantages of the present invention will emerge clearly from the following detailed description of an embodiment, given by way of non-limiting example, with reference to the appended drawings in which:

La figure 1 montre un train 1 de galet selon un mode de réalisation de l'invention. Le train 1 de galet est destiné à recevoir, notamment à supporter, un câble 2 d'entraînement aérien et porteur. Le train 1 de galet peut équiper par exemple un balancier d'une gare ou d'un pylône d'une installation de remontée mécanique, le câble 2 d'entraînement étant destiné à l'entraînement d'un ou plusieurs véhicules de remontée mécanique d'une station à l'autre de l'installation.The figure 1 shows a train 1 of roller according to one embodiment of the invention. The roller train 1 is intended to receive, in particular to support, a cable 2 aerial and carrier training. The roller train 1 can equip, for example, a balance wheel of a station or pylon of a ski lift installation, the drive cable 2 being intended for driving one or more ski lift vehicles. station at the other end of the installation.

Le train 1 de galet comprend un châssis 4, et au moins un galet 6 monté mobile en rotation, notamment libre en rotation, par rapport au châssis 4 autour d'un axe A de rotation qui peut être sensiblement orthogonal au câble 2 d'entraînement.The roller train 1 comprises a chassis 4, and at least one roller 6 rotatably mounted, in particular free to rotate, relative to the chassis 4 about an axis A of rotation which may be substantially orthogonal to the drive cable 2 .

De préférence, le train 1 de galet comprend une pluralité de galets 6 montés mobile en rotation sur un châssis 4 commun. Les galets 6 ont des axes de rotation parallèles et sont alignés les uns à la suite des autres dans un même plan orthogonal à leurs axes A de rotation.Preferably, the roller train 1 comprises a plurality of rollers 6 mounted to rotate on a common chassis 4. The rollers 6 have parallel axes of rotation and are aligned one after the other in the same plane orthogonal to their axes A of rotation.

Chaque galet 6 est supporté par un arbre 8 support qui s'étend à travers celui-ci et le relie au châssis 4. L'axe A de rotation coïncide avec l'arbre 8 support correspondant, c'est-à-dire que l'arbre 8 de support s'étend longitudinalement selon l'axe A.Each roller 6 is supported by a support shaft 8 which extends therethrough and connects it to the frame 4. The axis A of rotation coincides with the corresponding support shaft 8, that is to say that support shaft 8 extends longitudinally along the axis A.

Les galets 6 sont destinés à supporter le câble 2 d'entraînement. A cette fin, comme illustré sur la figure 1, les galets 6 peuvent comprendre une gorge 10 destinée à recevoir et maintenir le câble 2 d'entraînement.The rollers 6 are intended to support the drive cable 2. For this purpose, as illustrated on the figure 1 , the rollers 6 may comprise a groove 10 intended to receive and hold the drive cable 2.

Les galets 6 peuvent être de support ou de compression selon que le câble 2 d'entraînement s'étend respectivement au-dessus ou en-dessous de leur axe A de rotation.The rollers 6 may be of support or compression depending on whether the drive cable 2 extends respectively above or below their axis A of rotation.

Le train 1 de galet comprend un ou plusieurs dispositifs 12 de chauffage par conduction. Comme illustré sur la figure 1, le dispositif 12 de chauffage est positionné en applique, en contact direct, contre le châssis 4, afin de transmettre au châssis 4 la chaleur générée en fonctionnement.The roller train 1 comprises one or more conductive heating devices 12. As illustrated on the figure 1 , the heating device 12 is positioned in contact, in direct contact, against the frame 4, in order to transmit to the frame 4 the heat generated during operation.

Le châssis 4 est quant à lui configuré pour transmettre, par conduction, aux arbres 8 support la chaleur générée par le dispositif 12 de chauffage, afin d'éviter la formation de givre le long de l'axe A de rotation des galets 6. Les arbres 8 de support et le châssis 4 comprennent un matériau thermiquement conducteur, notamment la partie du châssis 4 en contact avec le dispositif 12 chauffant et la partie d'arbre 8 support en contact avec cette partie du châssis 4. De préférence, les arbres 8 de support et le châssis 4 sont métalliques.The chassis 4 is itself configured to transmit, by conduction, to the shafts 8 support the heat generated by the heating device 12, to prevent the formation of frost along the axis A of rotation of the rollers 6. The support shafts 8 and the frame 4 comprise a thermally conductive material, in particular the part of the frame 4 in contact with the heating device 12 and the part support 8 in contact with this part of the frame 4. Preferably, the support shafts 8 and the frame 4 are metallic.

Les arbres 8 de support sont avantageusement fixés au châssis 4, solidaires de celui-ci, afin de faciliter la conduction thermique. Ainsi, les galets 6 pivotent autour des arbres 8 support correspondants.The support shafts 8 are advantageously fixed to the frame 4, integral with the latter, to facilitate thermal conduction. Thus, the rollers 6 pivot around the corresponding support shafts 8.

On notera que le dispositif 12 de chauffage s'étend de préférence uniquement sur une partie fixe du train 1 de galet.It will be noted that the heating device 12 preferably extends only over a fixed part of the roller train 1.

Le dispositif 12 de chauffage est avantageusement du type comprenant une corde ou fil résistif électriquement conducteur et destiné à dégager de la chaleur par effet Joule. Ce fil résistif est enfermé dans une matrice électriquement isolante et thermiquement conductrice destinée à être plaquée contre le châssis 4. Le fil résistif comprend des extrémités s'étendant hors de cette matrice en vue d'être connectées à une alimentation électrique externe équipant l'installation qui comprend le train 1 de galet.The heating device 12 is advantageously of the type comprising an electrically conductive cord or resistive wire and intended to release heat by Joule effect. This resistive wire is enclosed in an electrically insulating and thermally conductive matrix intended to be pressed against the frame 4. The resistive wire comprises ends extending out of this matrix in order to be connected to an external power supply equipping the installation which includes the roller train 1.

En particulier, le dispositif 12 de chauffage peut être un tissu chauffant. Ce tissu chauffant peut comporter un fil 13 chauffant qui est destiné à dégager de la chaleur. Le fil 13 chauffant est par exemple un fil résistif électriquement conducteur destiné à dégager de la chaleur par effet Joule quand ce fil 13 est parcouru par un courant électrique.In particular, the heating device 12 may be a heating fabric. This heating fabric may comprise a heating wire 13 which is intended to release heat. The heating wire 13 is for example an electrically conductive resistive wire intended to release heat by Joule effect when the wire 13 is traversed by an electric current.

Le fil 13 chauffant peut être métallique et spiralé autour d'une âme en fibre de verre et qui est enfermé entre deux couches tissées de fibre de verre imprégnées d'élastomère de silicone.The heating wire 13 may be metal and spiral around a fiberglass core and is enclosed between two woven fiberglass layers impregnated with silicone elastomer.

On notera que le dispositif 12 de chauffage comprend avantageusement une double isolation électrique du fil résistant électriquement conducteur. Selon l'exemple de la figure 4, la double isolation électrique comprend une gaine 15a isolante entourant le fil 13 chauffant, et deux couches 15b isolantes entre lesquelles s'étendent le fil 13 chauffant et la gaine 15a. La gaine 15a peut être une extrusion du fil 13 chauffant, en élastomère de silicone, tandis que les deux couches 15b isolantes, par exemple en tissu de silicone, forment une matrice électriquement isolante encapsulant la gaine 15a et le fil 13 chauffant.It will be noted that the heating device 12 advantageously comprises a double electrical insulation of the electrically conductive resistant wire. According to the example of the figure 4 , the double electrical insulation comprises an insulating sheath 15a surrounding the heating wire 13, and two insulating layers 15b between which the heating wire 13 and the sheath 15a extend. The sheath 15a may be an extrusion of the heating wire 13, made of silicone elastomer, while the two insulating layers 15b, for example made of silicone fabric, form an electrically insulating matrix encapsulating the sheath 15a and the heating wire 13.

Le dispositif 12 de chauffage peut par ailleurs présenter une face 14 de contact destinée à venir en appui contre le châssis 4 afin de transmettre au châssis 4, par contact surfacique, la chaleur dégagée par le fil 13 chauffant. La face 14 est directement en appui contre le châssis 4 pour un meilleur rendement.The heating device 12 may furthermore have a contact face 14 intended to bear against the frame 4 in order to transmit the heat generated by the heating wire 13 to the frame 4 by surface contact. The face 14 is directly against the frame 4 for better performance.

Le train 1 de galet peut en outre comprendre des moyens de maintien configurés pour maintenir le dispositif 12 de chauffage, notamment la face 14 de contact, en appui contre le châssis 4. Les moyens de maintien peuvent comprendre par exemple un étau ou de la colle.The roller train 1 may further comprise holding means configured to hold the heating device 12, in particular the face 14 of contact, bearing against the frame 4. The holding means may comprise for example a vise or glue.

La face 14 d'appui peut donc être adhésive pour permettre de fixer le dispositif 12 de chauffage au châssis 4. Ainsi, le dispositif 12 de chauffage est collé au châssis 4.The bearing surface 14 can therefore be adhesive to enable the heating device 12 to be fixed to the frame 4. Thus, the heating device 12 is bonded to the frame 4.

De manière avantageuse, le train 1 de galet comprend des moyens d'isolation thermique destinés à isoler le dispositif 12 de chauffage de l'environnement extérieur, et plus précisément la partie du dispositif 12 de chauffage exposée à l'environnement extérieur.Advantageously, the roller train 1 comprises thermal insulation means intended to isolate the heating device 12 from the external environment, and more specifically the part of the heating device 12 exposed to the external environment.

Les moyens d'isolation thermique recouvrent au moins en partie le dispositif 12 de chauffage fixé contre le châssis 4.The thermal insulation means cover at least partially the heating device 12 fixed against the frame 4.

Les moyens d'isolation thermique comprennent par exemple une couche 16 en mousse destinée à protéger le dispositif 12 de chauffage des intempéries et du rayonnement ultraviolet du soleil.The thermal insulation means comprise, for example, a layer 16 made of foam intended to protect the device 12 from heating the weather and the ultraviolet radiation of the sun.

Cette couche d'isolation s'étend de préférence sur toute la partie du dispositif 12 de chauffage qui n'est pas au contact du châssis 4, c'est-à-dire qui est orientée vers l'extérieur. La couche d'isolation s'étend préférentiellement au moins sur une face du dispositif 12 de chauffage opposée à la face 14 en applique contre le châssis 4. Cette couche d'isolation est par exemple une mousse expansée de silicone. Cette couche d'isolation est avantageusement collée au dispositif 12 de chauffage.This insulating layer preferably extends over the entire part of the heating device 12 which is not in contact with the frame 4, that is to say which is facing outwards. The insulation layer preferably extends at least on one side of the heating device 12 opposite the face 14 applied against the frame 4. This insulation layer is for example an expanded foam of silicone. This insulation layer is advantageously bonded to the heating device 12.

Comme visible sur les figures, le châssis 4 peut être en forme de plaque 18 s'étendant dans un plan sensiblement perpendiculaire à l'axe A de rotation. La plaque 18 présente une face 20 interne du côté de laquelle sont situés les galets 6 et une face 22 externe opposée. Le dispositif 12 de chauffage est avantageusement agencé contre cette face 22 externe, c'est-à-dire contre la face opposée à celle à partir de laquelle s'étendent le ou les arbres 8 support.As shown in the figures, the frame 4 may be plate-shaped 18 extending in a plane substantially perpendicular to the axis A of rotation. The plate 18 has an inner face 20 on the side of which are located the rollers 6 and an opposite outer face 22. The heating device 12 is advantageously arranged against this outer face 22, that is to say against the face opposite to that from which extend the shaft or 8 support.

De préférence, le châssis 4 comprend aussi une deuxième plaque 24, qui s'étend de façon sensiblement parallèle à la première plaque 18, et qui est reliée à celle-ci par l'intermédiaire des arbres 8 support. Ainsi, les galets 6 sont agencés entre la première plaque 18 et la deuxième plaque 24.Preferably, the frame 4 also comprises a second plate 24, which extends substantially parallel to the first plate 18, and which is connected thereto via the support shafts 8. Thus, the rollers 6 are arranged between the first plate 18 and the second plate 24.

La deuxième plaque 24 a aussi une face 26 interne située en regard des galets 6 et une face 27 externe opposée. Le train 1 de galet comprend avantageusement un deuxième dispositif 12 de chauffage qui est agencé contre la deuxième plaque 24, de préférence contre la face 27 externe de cette deuxième plaque 24.The second plate 24 also has an inner face 26 facing the rollers 6 and an opposite outer face 27. The roller train 1 advantageously comprises a second heating device 12 which is arranged against the second plate 24, preferably against the external face 27 of this second plate 24.

Le châssis 4 peut par ailleurs comprendre un ou plusieurs dispositifs 28 d'entretoise reliant différentes parties du châssis 4, comme par exemple la première et la deuxième plaques 18, 24. Ce ou ces dispositifs 28 d'entretoise comprennent un matériau thermiquement conducteur, par exemple métallique, permettant d'établir un pont thermique entre les différentes parties de châssis 4 ainsi reliées. Cela permet un chauffage relativement uniforme et rapide de la structure du châssis 4 pour prévenir la formation de givre sur le châssis 4.The frame 4 may also comprise one or more spacer devices 28 connecting different parts of the frame 4, such as, for example, the first and the second plates 18, 24. This or these spacer devices 28 comprise a thermally conductive material, for example metal example, to establish a thermal bridge between the different parts of chassis 4 and connected. This allows a relatively uniform and rapid heating of the frame structure 4 to prevent the formation of frost on the frame 4.

Le ou les dispositifs 12 de chauffage s'étendent avantageusement à proximité des arbres 8 support. En particulier, comme visible sur les figures 1 à 3, le ou les dispositifs 12 de chauffage cernent au moins en partie les axes A de rotation des galets 6.The heating device or devices 12 advantageously extend close to the support shafts. In particular, as visible on Figures 1 to 3 the heating device or devices 12 at least partially define the axes A of rotation of the rollers 6.

Préférentiellement, le ou les dispositifs 12 de chauffage s'étendent sur la majeure partie, voire toute la superficie, de la face 22, 27 externe contre laquelle ces dispositifs 12 de chauffage sont en applique.Preferably, the heating device or devices 12 extend over most or even the entire surface area of the external face 22, 27 against which these heating devices 12 are applied.

Comme visible plus particulièrement sur les figures 2 et 3, le ou les arbres 8 support sont avantageusement reliés à une partie supérieure de la ou des plaques 18, 24, c'est-à-dire que la majeure partie des plaques 18, 24 s'étend sous les arbres 8 support. Le ou les arbres 8 support s'étendent au-dessus d'un plan médian de la ou des plaques 24. Les plaques 18, 24, et les dispositifs 12 de chauffage que ces plaques 18, 24 supportent, s'étendent ainsi essentiellement en regard d'une moitié inférieure du ou des galets 6. Cela permet une répartition optimale de la chaleur dégagée par le ou les dispositifs 12 de chauffage.As visible more particularly on figures 2 and 3 the support shaft or shafts 8 are advantageously connected to an upper part of the plate (s) 18, 24, that is to say that the majority of the plates 18, 24 extend under the support shafts. The support shaft or shafts extend above a median plane of the plate or plates 24. The plates 18, 24, and the heating devices 12 that these plates 18, 24 support, thus extend essentially in view of a lower half of the roller or rollers 6. This allows an optimal distribution of the heat generated by the or 12 heating devices.

L'invention a aussi pour objet une gare ou une installation 100 de remontée mécanique comprenant un ou plusieurs trains 1 de galet ayant tout ou partie des caractéristiques décrites précédemment, et plus particulièrement un pylône 102 ayant un balancier comprenant ce train 1 de galet.The invention also relates to a station or a lift installation 100 comprising one or more roller trains 1 having all or part of the characteristics described above, and more particularly a tower 102 having a balance comprising the train 1 roller.

Cette installation 100 peut comprendre deux stations d'extrémité (non représentées), dont une station d'extrémité aval et une station d'extrémité amont, le câble 2 aérien et porteur, des moyens d'entraînement de ce câble 2, comme par exemple une poulie, un ou plusieurs véhicules de remontée mécanique supportés par le câble 2, un ou plusieurs pylônes 102 répartis à intervalles prédéterminés entre les stations d'extrémité, l'un au moins de ces pylônes 102, de compression et/ou de support, ayant un balancier équipé d'au moins un train 1 de galet tel que décrit précédemment, et une sous-station d'alimentation électrique reliée au(x) dispositifs 12 de chauffage afin d'alimenter ceux-ci en courant électrique et permettre ainsi au(x) dispositifs 12 de chauffage de dégager de la chaleur pour empêcher la formation de givre ou le faire disparaître.This installation 100 may comprise two end stations (not shown), including a downstream end station and an upstream end station, the aerial cable 2 and carrier, drive means of this cable 2, such as for example a pulley, one or more lifts supported by the cable 2, one or more towers 102 distributed at predetermined intervals between the end stations, at least one of these pylons 102, compression and / or support, having a rocker arm equipped with at least one roller train 1 as described above, and a power supply substation connected to the (x) heating devices 12 in order to supply them with electric current and thus to enable the (x) Heating devices 12 release heat to prevent the formation of frost or make it disappear.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit ci-dessus, ce mode de réalisation n'ayant été donné qu'à titre d'exemple. Des modifications sont possibles, notamment du point de vue de la constitution des divers dispositifs ou par la substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described above, this embodiment having been given as an example. Modifications are possible, particularly from the point of view of the constitution of the various devices or by the substitution of technical equivalents, without departing from the scope of the invention.
