Abstract

The invention relates to a method allowing a bi-cable teleferic cabin (cable car), in conjunction with its own attachment 4, the variable-geometry haulage cable 1, its swing arm 15, the suspension cable 13, to uncouple, when stationary, at the entry to the station, run round the station and recouple, when stationary, onto the haulage cable, the latter participating in the manoeuvre in conjunction with the roller 2 itself controlled by the thrust cylinder 3. The method according to the invention is particularly intended for one-way bi-cable teleferics where the cabin is loaded when stationary.

Description

On sait qu'il existe différents types de téléphériques utilisant des cables dits porteurs associés a des cables dits tracteurs.We know that there are different types of cable cars using so-called carrier cables associated with so-called tractor cables.

Parmi ceux-ci, il existe une catégorie de téléphériques comportant des cabines munies d'attaches désaccouplables au niveau des stations. Ainsi la cabine se dessolidarise du cable tracteur tout en continuant de rouler sur le cable porteur ou sur un tube le remplaçant, pour contourner la station.Among these, there is a category of cable cars comprising cabins provided with uncouplable fasteners at the stations. Thus the cabin is detached from the tractor cable while continuing to roll on the carrying cable or on a tube replacing it, to bypass the station.

Ce contournement est réalisé grace à un système de trainage auxiliaire qui replace la cabine du coté de la station réservé au départ.This bypass is achieved thanks to an auxiliary drag system which replaces the cabin on the side of the station reserved for departure.

les perfectionnements qui font l'objet de la présente invention visent à.permettre de-résoudre la phase de désaccouplement, de contournement de la station, du réaccounlement sur le cable tracteur.the improvements which are the subject of the present invention are intended to enable the resolution of the uncoupling phase, bypassing the station, and re-coupling on the tractor cable.

t cet effet, le cable tracteur 1 est dévié en élévation de sa trajectoire par un galet 2 lui même commandé par un vérin 3, au moment de l'arrivée de la cabine en station. t this effect, the tractor cable 1 is deflected in elevation of its path by a roller 2 itself controlled by a jack 3, at the time of the arrival of the cabin in the station.

Dès que l'attache 4 fixée a la suspente 5 de la cabine 6, est présente dans la zône 7, la barre 8 commandée par le vérin 9, se baisse pour agir sur le levier 10 de l'attache 4 ce qui a pour effet d'ouvrir celle-ci.As soon as the fastener 4 fixed to the hanger 5 of the cabin 6 is present in the area 7, the bar 8 controlled by the jack 9, is lowered to act on the lever 10 of the fastener 4 which has the effect to open it.

Dès cet instant, le galet 2 passe en position haute ce qui permet au cable 1 de sortir nettement de l'attache.et de redémarrer à pleine vitesse sans risquer de par les vibrations, de frotter sur les mors I de l'attache 4.From this instant, the roller 2 goes to the high position which allows the cable 1 to come out clearly from the fastener. And to restart at full speed without risking vibration, to rub on the jaws I of fastener 4.

la figure 1 montre une vue en élévation représentant aussi bien le coté arrivée que le coté départ de la station.Figure 1 shows an elevational view showing both the arrival side and the departure side of the station.

On peut voir la poulie 12 contournée par le cable tracteur 1, le cable porteur '13 sur lequel roulent les roues14 du palonnier 15 , le trait pointillé long 16 représentant la trajectoire de l'attache 4 et notamment au dessus des galets supports 17. We can see the pulley 12 bypassed by the tractor cable 1, the carrying cable '13 on which the wheels 14 of the spreader 15 roll, the long dotted line 16 representing the trajectory of the fastener 4 and in particular above the support rollers 17.

La figure 2 montre le détail de l'attache 4 fixée sur la
suspente 5 . On peut voir les mors en contact avec le cable &
soit lia le mors fixe et 11 b le mors mobile.Figure 2 shows the detail of the fastener 4 fixed on the
line 5. We can see the jaws in contact with the cable &
either bind the fixed jaw and 11b the movable jaw.

Be ressort précontraint lu pousse le mors mobile 11b contre le cable par l'intermédiaire de la rondelle 19 , des butées mobiles 20 a, 20 b . Be prestressed read spring pushes the movable jaw 11b against the cable by means of the washer 19, movable stops 20a, 20b.

Pour permettre de sortir le cable de l'attache, le vérin 9
par la barre 6 appuie sur le levier 10 qui, de par ses articu
lations, tire sur la tige 21 qui elle même surcomprime le
ressort 1o par l'intermédiaire de l'axe 22 et de la rondelle
19
Dompte tenu que l'axe du cable 1 est décalé côté mors fixe
par rapport à l'axe normal 23, par la présence de l'ensemble
de la cabine dans-les zones 7 a et 7 b correspondant aux lieu
de solidarisation et de désolidaridation, celui-ci exerce une
force tendant à écarter le mors mobile 11 b
C'est cette force qui permet donc l'ouverture du mors mobile
des l'action induite sur le levier 10
Côt départ de la station, le même décalage du cable 1 permet
permet G ce dernier de retrouver sa place dans l'attache 4
en évitant le bec supérieur du mors fixe lita. To allow the cable to be removed from the clip, the jack 9
by the bar 6 presses on the lever 10 which, by its articu
lations, pull on the rod 21 which itself overcompresses the
spring 1o via axis 22 and washer
19
Given that the axis of cable 1 is offset on the fixed jaw side
relative to the normal axis 23, by the presence of the assembly
of the cabin in-zones 7 a and 7 b corresponding to the place
of solidarity and decoupling, it exercises a
force tending to spread the movable jaw 11 b
It is this force which therefore allows the opening of the movable jaw.
action induced on lever 10
On the departure side of the station, the same offset of cable 1 allows
allows G the latter to find its place in the fastener 4
avoiding the upper beak of the lita fixed jaw.

On peut voir aussi le verrou 24 solidaire de l'écrou de fixation
25 de l'attache 4, normalement relevé par son ressort 26, le
tout collaborant avec la barre 27 coulissant verticalement
sur les axes 28 a et b eux-mêmes solidaires de l'infrastructure
de la station.We can also see the lock 24 secured to the fixing nut
25 of the fastener 4, normally raised by its spring 26, the
all collaborating with the bar 27 sliding vertically
on axes 28 a and b, which are themselves integral with the infrastructure
from the station.

Be fonctionnement est le suivant:
Une cabine arrive dans la zône 7 et s'arrête. A ce moment, la
barre 27 exerce une force,due à sa masse,sur le verrou 24 qui vient en butée sur le levier 10. Le vérin 9 est alors actionné
pour déplacer le levier 10 vers le bas, ouvrant ainsi l'attache.The operation is as follows:
A cabin arrives in area 7 and stops. At this moment
bar 27 exerts a force, due to its mass, on the latch 24 which abuts on the lever 10. The jack 9 is then actuated
to move the lever 10 down, thus opening the clip.

Dès que le levier est suffisamment écarté, le verrou 24 vient
se glisser entre le corps de l'attache et le levier 10.As soon as the lever is sufficiently apart, the latch 24 comes
slip between the body of the fastener and the lever 10.

le vérin est aussitôt relevé et le levier vient coincer le verrou 24 ce qui à pour effet de maintenir l'attache ouverte. the cylinder is immediately raised and the lever jams the latch 24 which has the effect of keeping the fastener open.

Ainsi, le contournement de la station est effectué avec l'atta
che ouverte jusqu'au positionnement de l'attache dans la zône
7 de réaccouplement côté départ de la station. Thus, bypassing the station is carried out with the attack.
che open until the clip is positioned in the area
7 for re-coupling on the departure side of the station.

A cet endroit, on retrouve les mêmes éléments de commandes sans toutefois la barre 27 de commande du verrou 24.At this point, the same control elements are found without, however, the bar 27 for controlling the latch 24.

Le dérlement chronolcgique des opérations de réaccouplement de l'attache 4 sur 1 cable tracteur 7, est le suivant: le vérin 3 pousse le galet 2 pour remettre le cable 1 entre les mors de l'attache.The chronological sequence of operations for re-coupling the fastener 4 on 1 tractor cable 7 is as follows: the jack 3 pushes the roller 2 to put the cable 1 between the jaws of the fastener.

le vérin 9 exerce une pression sur le levier 10 créant un petit déplacement permettant au verrou 24 de se libérer entre montant en position haute par l'action de son ressort 26.the jack 9 exerts pressure on the lever 10 creating a small movement allowing the lock 24 to be released between the upright in the high position by the action of its spring 26.

le circuit hydraulique du vérin 9 est alors aiguillé vers une vanne dont l'agencement ne permet un débit de vidange du vérin que si ce dernier applique une pression minimum donnant l'ima ge,d'une force correcte induite par la détente du ressort 18 de l'attache.the hydraulic circuit of the jack 9 is then directed to a valve, the arrangement of which allows the jack to be drained only if the latter applies a minimum pressure giving the image, of a correct force induced by the relaxation of the spring 18 of the fastener.

Cet agencement permet de contrôler avant chaque départ, le rendement mécanique des axes d'articulation du levier 10.This arrangement makes it possible to control, before each departure, the mechanical efficiency of the axes of articulation of the lever 10.

Dès le retour du vérin en positon haute, un contact 28 placé sur le haut de la tige du vérin 9, vérifie que la force du ressort I & de l'attache est correcte sur toute sa course.As soon as the cylinder returns to the high position, a contact 28 placed on the top of the cylinder rod 9, verifies that the spring force I & of the fastener is correct over its entire travel.

il est à noter que si le verrou 4 était empoché de pénétrer tout ou partie dans son lieu de calage par un corps étranger (givre, glace etc), un contact 29, placé en aval du lieu de désaccouplement viendrait signaler la non pénétration complète du verrou de calage.it should be noted that if the lock 4 was pocketed to penetrate all or part of its stalling place by a foreign body (frost, ice, etc.), a contact 29, placed downstream of the uncoupling place would signal the complete non penetration of the timing lock.

En effet, cet aménagement garantit le libre åeu 30 permettant au ressort 18 d'exercer son effort sur le cable 1.Indeed, this arrangement guarantees free åeu 30 allowing the spring 18 to exert its force on the cable 1.

Ainsi, avant chaque départ d'une cabine, un contrôle garantit, quelque soit la circonstance, le bon serrage de l'attache sur le cable.Thus, before each departure from a cabin, a control guarantees, whatever the circumstance, the correct tightening of the fastener on the cable.

La figure 4 montre en vue de dessus le palonnier 15 roulant sur le cable porteur 13 dans la zône de contournement de la station.Figure 4 shows a top view of the spreader 15 rolling on the carrying cable 13 in the bypass area of the station.

Pour que les roues 14 puissent rouler correctement sur la courbe, il convient que 'l'axe de chaque roue soit perpendiculaire à la tangente de la courbe. Pour répondre à cette exigen ce, le palonnier comporte des articulations en plan 31 a à a. So that the wheels 14 can roll correctly on the curve, the axis of each wheel should be perpendicular to the tangent of the curve. To meet this requirement, the lifter has planar joints 31 a to a.

munies chacune d'un axe de blocage 32 (fig.5) collaborant avec une patte 33 comportant un alésage 34.each provided with a locking pin 32 (fig. 5) collaborating with a tab 33 having a bore 34.

Be fonctionnement est le suivant
En amont de la courbe, un rail 3 soulève les leviers 36 de chaque articulation qui libèrent ainsi les axes 32 (fig6) de leurs alésages 34.Be functioning is as follows
Upstream of the curve, a rail 3 lifts the levers 36 of each articulation which thus release the pins 32 (fig6) from their bores 34.

Ainsi dès l'abord de la courbe, les roues 14 s'auto-alignent sur la tangente de la courbe Ia butée 37 interdit une orientation assymétrique pour chaque élément du palonnier.Thus from the start of the curve, the wheels 14 self-align on the tangent of the curve. The stop 37 prohibits an asymmetrical orientation for each element of the lifter.

En sortie de courbe, les roues 14 s'auto-alignent à nouveau sur la partie droite ce qui à pour effet de remettre en regard les alésages par rapport aux axes 32 qui, par l'action de la gravité, reviennent en place rigidifiant à nouveau le palonnier en plan.At the end of the curve, the wheels 14 self-align again on the right-hand side, which has the effect of bringing the bores back into relation with respect to the axes 32 which, by the action of gravity, come back into place stiffening at again the lifting beam in plan.

La figure 5 contre en outre, l'axe 3u qui avec le palier 39 réalise l'articulation en élévation normale du palonnier.Figure 5 against against, the axis 3u which with the bearing 39 provides the articulation in normal elevation of the lifter.

Ia figure y montre la vue en élévation du palonnier roulant sur la courbe. Ia figure there shows the elevation view of the spreader on the curve.

il est à noter que le blocage des articulations en plan est obligatoire pour une bonne tenue du palonnier à grande vitesse sur le cable après acceleration hors de la station.it should be noted that the locking of the planar joints is compulsory for good behavior of the spreader at high speed on the cable after acceleration out of the station.

En variante, un rail supplémentaire situé en sortie de courbe à la verticale des axes 3 > , vérifie que les axes sont bien descendus dans leur logement respectif.As a variant, an additional rail located at the end of the curve vertical to the axes 3>, checks that the axes have indeed descended into their respective housings.

Ce rail, articulé dans le sens vertical, est muni d'un contact destiné à contrôler le bon replacement des axes 32 dans leurs alésages 34.This rail, articulated in the vertical direction, is provided with a contact intended to control the correct replacement of the axes 32 in their bores 34.

il est à noter que le corps extérieur de l'attache 4 est conçu d'une seule pièce comportant une ouverture occupée par le mors mobile Il b. Cette ouverture permet de sortir sans démontage préalable, tout le mécanisme intérieur.it should be noted that the external body of the fastener 4 is designed in one piece having an opening occupied by the movable jaw It b. This opening allows to exit without prior disassembly, the entire interior mechanism.

Pour ce faire, le ressort 18 est éventuellement constitué en plusieurs parties ayant une longueur compatible avec la dite ouverture. Une ouverture 40 dans le mors fixe 11 a, permet d'introduire un outil pour décomprimer le ressort 18 et sortir le tout en otant l'axe 41 hors contrainte. To do this, the spring 18 is optionally made up of several parts having a length compatible with said opening. An opening 40 in the fixed jaw 11 a makes it possible to introduce a tool for decompressing the spring 18 and removing it while removing the axis 41 without stress.
