La mise en oeuvre d'une telle chaîne cinématique de transmission est compliquée, et nécessite un encombrement longitudinal important dans la station. La diversité des sous-ensembles, et le temps de montage et de réglage des équipements, augmentent le nombre d'intervenants et le prix de revient de ces installations connues.The vertical axis drive pulley of the single-cable fixed chairlifts is conventionally rotated by a conical torque transmission system allowing a right-angle return of a rotational movement from a geared motor arranged horizontally on a platform elevated from the station. The implementation of such a kinematic transmission chain is complicated, and requires significant longitudinal congestion in the station. The diversity of subsets, and the time of assembly and adjustment of equipment, increase the number of stakeholders and the cost of these known installations.

Description d'un mode de réalisation préférentiel.Description of a Preferred Embodiment

Sur les figures 1 à 4, un câble porteur-tracteur 10 aérien d'un télésiège passe autour d'une poulie de renvoi 12 à axe vertical logée dans une gare ou station d'extrémité 14. Le câble 10 s'étend en boucle sans fin le long d'une voie montante, et d'une voie descendante, et les sièges, dont l'un 16 est représenté sur la figure 2, sont accrochés au câble 10 à intervalles réguliers par des pinces 18 de retenue fixes.On the Figures 1 to 4 , an aerial tractor-carrying cable 10 of a chairlift passes around a vertical axis pulley 12 housed in a station or end station 14. The cable 10 extends in an endless loop along a uplink, and a descending lane, and the seats, one of which 16 is depicted on the figure 2 are hooked to the cable 10 at regular intervals by fixed retaining clips 18.

La station 14 illustrée à la figure 1, est une station aval motrice, dans laquelle la poulie de renvoi 12 horizontale est entraînée en rotation par un mécanisme motoréducteur 20 s'étendant perpendiculairement à la poulie 12, l'ensemble étant porté par un dispositif de support 22 avec un décalage en hauteur prédéterminé.Station 14 illustrated at figure 1 , is a driving downstream station, in which the horizontal idler pulley 12 is rotated by a geared motor mechanism 20 extending perpendicular to the pulley 12, the assembly being carried by a support device 22 with a predetermined height offset .

Le dispositif de support 22 est composé d'un socle 24 fixe en béton ancré au sol, et d'un châssis 26 métallique horizontal comprenant des profilés fixes 28 en l, et un chariot 30 monté à translation horizontale par l'intermédiaire d'organes de roulement 32.The support device 22 is composed of a fixed concrete base 24 anchored to the ground, and a horizontal metal frame 26 comprising fixed profiles 28 in l, and a carriage 30 mounted in horizontal translation through organs rolling 32.

La poulie 12 et le mécanisme motoréducteur 20 sont montés sur l'une des extrémités du chariot 30. La course longitudinale du chariot 30 s'étend sur une longueur de l'ordre de 3 mètres entre les positions A et B de la figure 3, pour assurer la tension du câble 10. Un dispositif tendeur, formé par exemple par un vérin 66 ou un contrepoids, est associé au chariot de manière à agir dans la direction de la ligne.The pulley 12 and the geared motor mechanism 20 are mounted on one of the ends of the carriage 30. The longitudinal travel of the carriage 30 extends over a length of about 3 meters between the positions A and B of the figure 3 , to ensure the tension of the cable 10. A tensioning device, formed for example by a jack 66 or a counterweight, is associated with the carriage so as to act in the direction of the line.

Le mécanisme motoréducteur 20 comporte un moteur électrique 34 disposé sous la poulie 12, et un réducteur 36 de vitesse agencé au-dessus de la poulie 12, et en alignement coaxial avec le moteur 34. L'arbre de sortie vertical du moteur 34 est muni d'un volant 37 d'inertie, et traverse un fourreau 38 tubulaire assujetti au chariot 30, de manière à constituer l'arbre 40 à grande vitesse accouplé à l'entrée du réducteur 36.The geared motor mechanism 20 comprises an electric motor 34 disposed under the pulley 12, and a speed reducer 36 arranged above the pulley 12, and aligned coaxially with the motor 34. The vertical output shaft of the motor 34 is provided with of a flywheel 37 of inertia, and passes through a tubular sleeve 38 secured to the carriage 30, so as to constitute the shaft 40 at high speed coupled to the input of the gearbox 36.

Le réducteur 36 mécanique est doté de plusieurs étages d'engrenages 42 démultiplicateurs, et d'un arbre de sortie 44 à petite vitesse pour l'entraînement en rotation de la poulie 12. Une paire de roulements 46 est intercalée coaxialement entre le fourreau 38 fixe et un alésage 48 cylindrique du moyeu 50 de la poulie 12. L'arbre de sortie 44 du réducteur 36 est creux, et est accouplé directement à un manchon 52 d'entraînement fixé au moyeu 50 par des vis et pions 54 d'assemblage. Le carter du réducteur 36 est supporté par une paire de bras de couple 55.The mechanical gearbox 36 is provided with several stages of reduction gears 42 and an output shaft 44 at a low speed for driving the pulley 12 in rotation. A pair of bearings 46 is interposed coaxially between the fixed sleeve 38 and a cylindrical bore 48 of the hub 50 of the pulley 12. The output shaft 44 of the gearbox 36 is hollow, and is coupled directly to a drive sleeve 52 fixed to the hub 50 by screws and 54 pieces of assembly. The housing of the gearbox 36 is supported by a pair of torque arms 55.

Les deux arbres 40, 44 sont coaxiaux en s'étendant perpendiculairement par rapport à la poulie 12. Le montage modulaire en ligne d'arbres du mécanisme motoréducteur 20 permet d'obtenir une chaîne cinématique courte sans nécessiter des moyens de transmission intercalaires du type couple conique. La structure d'entraînement selon l'invention permet de réduire le temps de montage, ainsi que l'encombrement longitudinal de la station 14.The two shafts 40, 44 are coaxial extending perpendicularly with respect to the pulley 12. The modular in-line shaft assembly of the geared motor mechanism 20 makes it possible to obtain a short kinematic chain without the need for inter-torque transmission means of the torque type. conical. The drive structure according to the invention makes it possible to reduce the assembly time as well as the longitudinal space requirement of the station 14.

Un train de galets 56 est monté sur un balancier 58 articulé à l'entrée de la station 14 autour d'un axe transversal 60 de manière à dévier le câble 10 vers le bas en direction de la poulie 12.A roller train 56 is mounted on a rocker arm 58 articulated at the inlet of the station 14 around a transverse axis 60 so as to deflect the cable 10 downwards toward the pulley 12.

Une roue dentée 62 de secours est rigidement fixée à la face inférieure de la poulie 12 pour coopérer avec un moteur de secours 64 solidaire du chariot 30. Le moteur de secours 64 peut un motoréducteur électrique entraîné par un groupe électrogène, ou un moteur hydraulique. La poulie de renvoi 12 peut ainsi être entraînée en rotation par le moteur de secours 64 en cas d'intervention sur le mécanisme motoréducteur 20.A spare gear wheel 62 is rigidly fixed to the underside of the pulley 12 to cooperate with an emergency engine 64 integral with the carriage 30. The emergency engine 64 may an electric geared motor driven by a generator, or a hydraulic motor. The return pulley 12 can thus be rotated by the emergency engine 64 in case of intervention on the geared motor mechanism 20.

Le montage de la poulie de renvoi 12 sur le chariot 30 mobile, et l'utilisation d'éléments standards pour constituer le mécanisme motoréducteur 20, permettent d'obtenir une modularité des sous-ensembles de stations de télésièges.The mounting of the pulley 12 on the movable carriage 30, and the use of standard elements to constitute the geared motor mechanism 20, allow to obtain a modularity of the subassemblies of chairlift stations.

Dans le cas d'une station aval 14 selon la figure 1, la poulie 12 est une poulie motrice entraînée en rotation par le mécanisme motoréducteur 20. Le déplacement vers la droite du chariot 30 (flèche F, figure 3) entre les positions A et B, permet en plus d'assurer une tension du câble 10.In the case of a downstream station 14 figure 1 , the pulley 12 is a driving pulley rotated by the geared motor mechanism 20. The displacement to the right of the carriage 30 (arrow F, figure 3 ) between the positions A and B, in addition makes it possible to ensure a tension of the cable 10.

La poulie 12 peut également être transformée en simple poulie de tension, par exemple pour la station amont du télésiège. Dans ce cas, le moteur électrique 34 et le réducteur 36 ne sont pas montés. II suffit de supprimer la liaison d'accouplement du réducteur 36 et du moteur électrique 34 avec la poulie 12. En coulissant sous l'action du vérin 66 du dispositif tendeur agissant dans la direction de la ligne, le chariot 30 maintient le câble 10 en permanence sous tension constante.The pulley 12 can also be transformed into a simple tension pulley, for example for the upstream station of the chairlift. In this case, the electric motor 34 and the gearbox 36 are not mounted. It is sufficient to remove the coupling connection of the gearbox 36 and the electric motor 34 with the pulley 12. Sliding under the action of the jack 66 of the tensioning device acting in the direction of the line, the carriage 30 holds the cable 10 in position. constant under constant voltage.

Selon une variante sans réducteur mécanique, le moteur peut être équipé d'un commutateur électronique de vitesse pour l'entraînement direct de la poulie à axe vertical.According to a variant without a mechanical gearbox, the motor can be equipped with an electronic speed switch for the direct drive of the vertical axis pulley.
