Description

L'invention concerne une installation de transport de produit ou de personnes, à câble aérien.The invention relates to an installation for transporting products or people, with overhead cable.

On connait déjà des installations de transport de produit ou de personnes, à câble aérien, du type comportant ou un plusieurs câbles aériens porteurs, tracteurs se tendant entre deux stations d'extrémité respectivement de chargement ou d'embarquement et de déchargement ou débarquement avec éventuellement une ou plusieurs stations intermédiaires, maintenus et guidés par des galets support et des galets de compression portés par un ou plus généralement plusieurs pylônes répartis entre les stations et auxquels sont associés de manière fixe ou débrayable un ou plusieurs véhicules -notamment des cabines-. Ces installations sont de type pulsé ou va et vient ou de tout autre type.There are already known installations for transporting products or people, overhead cable, of the type comprising or one or more overhead carrier cables, tractors stretching between two end stations respectively for loading or boarding and unloading or disembarking with possibly one or more intermediate stations, maintained and guided by support rollers and compression rollers carried by one or more generally several pylons distributed between the stations and with which one or more vehicles (in particular cabins) are associated in a fixed or disengageable manner. These installations are of the pulsed or back and forth type or of any other type.

Souvent, les galets sont associées par paires en étant montés aux deux extrémités de balanciers primaires articulés dans leur partie médiane aux deux extrémités de balanciers secondaires, eux- mêmes montés de la même manière sur un ou des balanciers tertiaires et ainsi de suite, selon le nombre de galets. Le dernier balancier forme une poutre montée articulée dans sa partie médiane à une potence du pylône. Une telle structure a l'avantage d'être standardisée, de permettre aux galets de suivre le cheminement du câble, quel que soit son état de charge, de conduire à une répartition homogène de la charge sur les galets. Cette structure est particulièrement bien adaptée à une charge répartie comme c'est le cas lorsque les cabines ont un poids unitaire compris entre 300 kilogrammes et 1,5 tonne environ, deux cabines voisines étant écartées l'une de l'autre d'une distance comprise entre 15 mètres et 45 mètres environ (ce qui correspond à une charge répartie moyenne de l'ordre de 30 kilogrammes par mètre linéaire).Often, the rollers are associated in pairs by being mounted at the two ends of primary pendulums articulated in their middle part at the two ends of secondary pendulums, themselves mounted in the same way on one or more tertiary pendulums and so on, depending on the number of rollers. The last pendulum forms a mounted beam articulated in its middle part to a gallows of the pylon. Such a structure has the advantage of being standardized, of allowing the rollers to follow the path of the cable, whatever its state of charge, to lead to a homogeneous distribution of the load on the rollers. This structure is particularly well suited to a distributed load, as is the case when the cabins have a unit weight of between 300 kg and approximately 1.5 tonnes, two neighboring cabins being spaced apart from each other by a distance between approximately 15 meters and 45 meters (which corresponds to an average distributed load of around 30 kilograms per linear meter).

Cependant, si l'on envisage une charge concentrée et non répartie, cette structure présente de sérieux inconvénients. Dans ce cas, la charge est d'une part relativement importante -notamment de l'ordre de 1,5 ù 2,5 tonnes par mètre linéaire- et d'autre part concentrée sur une longueur limitée -notamment de l'order de 3 à 6 mètres. Ceci se produit avec des cabines importantes se suivant à proximité immédiate l'une de l'autre. Dans cette hypothèse, et du fait de la concentration de la charge sur le câble, ce dernier peut se déplacer brusquement et avec une grande amplitude lorsque les véhicules passent au droit d'un pylône. Cela conduit à un mouvement de balancelle des véhicules toujours gênant surtout s'il s'agit de cabines pour des passagers, dont le confort est alors loin d'être satisfaisant. Cet inconvénient est d'autant plus grand que la vitesse linéaire du câble est grande.However, if one considers a concentrated and not distributed load, this structure has serious drawbacks. In this case, the load is on the one hand relatively large - in particular of the order of 1.5 to 2.5 tonnes per linear meter - and on the other hand concentrated over a limited length - in particular of the order of 3 at 6 meters. This occurs with large cabins following each other in close proximity to each other. In this case, and due to the concentration of the load on the cable, the latter can move suddenly and with great amplitude when the vehicles pass in front of a pylon. This leads to a vehicle swing movement which is always troublesome, especially if it is a cabin for passengers, the comfort of which is far from satisfactory. This disadvantage is all the greater the greater the linear speed of the cable.

Le brevet américain US-A-4 363 945 décrit un dispositif de détection du déraillement d'un câble supporté par un train de galets, mais ne fournit aucune solution au problème visé ci- dessus.American patent US-A-4 363 945 describes a device for detecting the derailment of a cable supported by a train of rollers, but does not provide any solution to the problem referred to above.

L'invention se propose d'apporter une solution à ces inconvénients. A cet effet, elle propose une installation conforme à la revendication 1.The invention proposes to provide a solution to these drawbacks. To this end, it offers an installation in accordance with claim 1.

En contrepartie, de telles structures selon l'invention ne peuvent être totalement standardisées, comme le souhaitent habituellement les concepteurs et constructeurs, et doivent être calculées et adaptées à chaque cas particulier. De même, contrairement aux souhaits habituels des concepteurs et constructeurs, la charge n'est pas nécessairement également répartie sur les galets.In return, such structures according to the invention cannot be totally standardized, as usually desired by designers and constructors, and must be calculated and adapted to each particular case. Similarly, contrary to the usual wishes of designers and builders, the load is not necessarily evenly distributed on the rollers.

L'invention sera bien comprise grâce à la description qui suivra en référence aux dessins annexés dans lesquels:

  • La figure 1 est une vue schématique d'une forme de réalisation possible d'une installation selon l'invention.
  • La figure 2 est une vue schématique partielle, à plus grande échelle, en élévation, d'un pylône d'une installation selon l'invention en l'occurence un train de galets supports, dans un état de charge possible.
  • La figure 3 est une vue schématique de côté du pylône représenté sur la figure 2.
  • La figure 4 est une vue en élévation d'une poutre fixe d'un pylône selon l'invention avec plusieurs courbes de référence possibles; celles-ci n'étant pas limitatives.
  • La figure 5 est une vue schématique en élévation du train de galets représenté sur la figure 2 dans une autre état de charge possible.
The invention will be better understood from the description which follows with reference to the accompanying drawings in which:
  • Figure 1 is a schematic view of a possible embodiment of an installation according to the invention.
  • Figure 2 is a partial schematic view, on a larger scale, in elevation, of a pylon of an installation according to the invention in this case a train of support rollers, in a possible state of charge.
  • FIG. 3 is a schematic side view of the pylon shown in FIG. 2.
  • Figure 4 is an elevational view of a fixed beam of a pylon according to the invention with several possible reference curves; these are not limiting.
  • Figure 5 is a schematic elevational view of the roller train shown in Figure 2 in another possible state of charge.

Ou se réfère maintenant à la figure 1 qui représente une installation de transport de produit ou de personnes à câble aérien, du type comportant un ou plusieurs câbles aériens 1, porteurs, tracteurs, s'étendant entre deux stations d'extrémité respectivement de chargement ou d'embarquement 2a et de déchargement ou débarquement 2b, avec éventuellement une ou plusieurs stations intermédiaires (non représentées), maintenus et guidés par des galets supports et des galets de compression 3 portés par un ou plus généralement plusieurs pylônes 4 répartis entre les stations et auxquels sont associés, de manière fixe ou débrayable, un ou plusieurs véhicules 5 notamment des cabines.Or now referring to FIG. 1 which represents an installation for transporting a product or people with overhead cable, of the type comprising one or more overhead cables 1, carriers, tractors, extending between two end stations respectively for loading or boarding 2a and unloading or disembarking 2b, possibly with one or more intermediate stations (not shown), maintained and guided by support rollers and compression rollers 3 carried by one or more generally several pylons 4 distributed between the stations and which are associated, in a fixed or disengageable manner, one or more vehicles 5 in particular cabins.

L'installation est de type pulsé ou va et vient, ou de tout autre type, sous réserve de ce qui est mentionné ci-dessous en ce qui concerne son caractère "à charge concentrée". Elle comporte un ou plusieurs câbles porteurs et tracteurs ou encore plusieurs câbles chacun porteur ou tracteur. Dans la suite du texte, ou parle "du" câble sans autre précision, ce qui se réfère donc à toutes les variantes possibles.The installation is of the pulsed or back and forth type, or of any other type, subject to what is mentioned below as regards its "concentrated load" character. It comprises one or more carrying cables and tractors or even several cables each carrying or tractor. In the rest of the text, or speaks "of" cable without further specification, which therefore refers to all possible variants.

Ainsi qu'il est mentionné plus haut, l'installation est de type "à charge concentrée", c'est-à-dire que la répartition des véhicules 5 le long du câble 1 et le capacité des véhicules 5 sont telles que la charge qu'ils exercent sur le câble 1 est d'une part relativement importante -notamment de l'ordre de 1,5 à 2,5 tonnes par mètre linéaire-et, d'autre part, concentrée sur une longueur limitée -notamment de l'ordre de 3 à 6 mètres-. Le cas d'une installation à charge concentrée se présente avec plusieurs cabines -par exemple trois- se suivant à proximité immédiate l'une de l'autre et éventuellement associées l'une à l'autre.As mentioned above, the installation is of the "concentrated load" type, that is to say that the distribution of the vehicles 5 along the cable 1 and the capacity of the vehicles 5 are such that the load that they exert on the cable 1 is on the one hand relatively large - in particular of the order of 1.5 to 2.5 tonnes per linear meter - and, on the other hand, concentrated over a limited length - in particular of l '' order from 3 to 6 meters. The case of a concentrated load installation is present with several cabins - for example three - following each other in close proximity to each other and possibly associated with one another.

Les valeurs indiquées ne sont pas à considérer strictement, mais permettent d'opposer une installation selon l'invention aux installations de l'etat connu de la technique, à charge répartie (charge moyenne répartie de l'ordre de 30 kilogrammes par mètre linéaire de câble et véhicules espacés les uns des autres de 15 à 45 mètres environ).The values indicated are not to be considered strictly, but allow an installation according to the invention to be opposed to installations of the known state of the art, with distributed load (average distributed load of the order of 30 kilograms per linear meter of cable and vehicles spaced approximately 15 to 45 meters apart).

Préférentiellement, l'installation est également du type à défilement rapide, la vitesse linéaire de éfilement du câble 1 étant comprise entre 7 et 8 mètres par seconde, notamment égale ou de l'ordre de 7,5 mètres par seconde.Preferably, the installation is also of the fast-scrolling type, the linear threading speed of the cable 1 being between 7 and 8 meters per second, in particular equal to or of the order of 7.5 meters per second.

Ainsi que cela est représenté sur les figures 2 et 3, un pylône 4 comporte au moins une poutre fixe 6 portée par au moins une potence 7 et sur laquelle sont montés les galets 3 (support ou de compression).As shown in Figures 2 and 3, a pylon 4 has at least one fixed beam 6 carried by at least one bracket 7 and on which are mounted the rollers 3 (support or compression).

Les galets 3 sont donc individuellement ou par groupes -notamment par paires comme dans l'exemple représenté- totalement indépendants des galets 3 ou des groupes de galets 3 voisins (ceci par opposition à l'état de la technique ou d'une extrémité à l'autre d'un train de galets, les galets sont associés cinématiquement les uns aux autres grâce aux balanciers primaires et secondaires, etc.... articulés).The rollers 3 are therefore individually or in groups - in particular in pairs as in the example shown - completely independent of the rollers 3 or of the neighboring groups of rollers 3 (this as opposed to the prior art or from one end to the other). 'other of a train of rollers, the rollers are kinematically associated with each other thanks to the primary and secondary pendulums, etc. articulated).

Cette structure a pour fonction d'imposer au moins partiellement le cheminement ou des limites au cheminement du câble 1 (ceci par opposition à l'état de la technique où c'est le cheminement du câble qui détermine la position des galets). Cette structure permet donc d'éviter le déplacement brusque et de grande amplitude du câble 1, lorsque les véhicules 5 passent au droit d'un pylône 4.The function of this structure is to impose at least partially the routing or limits to the routing of the cable 1 (this as opposed to the prior art where it is the routing of the cable which determines the position of the rollers). This structure therefore makes it possible to avoid the sudden and large amplitude movement of the cable 1, when the vehicles 5 pass in line with a pylon 4.

Ainsi, grâce à l'invention, on évite que les véhicules 5 constituant une charge concentrée ne soient affectés d'un mouvement de balancelle en passant au droit d'un pylône 4, alors même que les véhicules 5 crééent sur le câble 1 une charge concentrée.Thus, thanks to the invention, it is avoided that the vehicles 5 constituting a concentrated load are affected by a swinging movement while passing in line with a pylon 4, even though the vehicles 5 create a load on the cable 1 concentrated.

Les galets 3 sont montés sur la poutre fixe 6 le long d'une courbe de référence C. Cette courbe de référence C est une courbe intermédiaire entre les différentes courbes correspondant aux différents états de charge possibles. La courbe C peut, par exemple, correspondre à l'état ou le câble 1 subit la charge maximale. La courbe C peut correspondre à un état de charge soit particulier, soit fictif entre les différents états de charge possibles et ceci selon la configuration de l'installation.The rollers 3 are mounted on the fixed beam 6 along a reference curve C. This reference curve C is an intermediate curve between the different curves corresponding to the different possible states of charge. The curve C can, for example, correspond to the state where the cable 1 undergoes the maximum load. Curve C can correspond to a particular or fictitious state of charge between the different possible states of charge, depending on the configuration of the installation.

Cette courbe C est déterminée par calcul pour chaque implantation particulière. Dans certains cas, cette courbe C peut être à concavité, tournée vers le haut ou vers le bas et se rapprocher d'une parabole ou d'une chainette. Elle peut avoir aussi, dans d'autres cas, une forme plus complexe.This curve C is determined by calculation for each particular location. In some cases, this curve C can be concavity, turned upwards or downwards and approach a parabola or a chain. In other cases, it can also have a more complex form.

Préférentiellement et pour des raisons de résistance, la courbe C s'étend dans la partie médiane de la poutre fixe 6. Pour cette raison, la poutre fixe 6 peut avoir des formes plus ou moins complexes selon les cas.Preferably and for reasons of resistance, the curve C extends in the middle part of the fixed beam 6. For this reason, the fixed beam 6 can have more or less complex shapes depending on the case.

La poutre fixe 6 peut avoir, en particulier, une forme générale de pseudo segment circulaire, ce qui permet de l'utiliser avec des courbes de référence différentes. Cette caractéristique qui permet une certaine standardisation est illustrée par la figure 4 sur laquelle on voit qu'une même poutre fixe 6 peut concerner plusieurs-en l'oc- curence trois- courbes de référence C1, C2, C3, etc. Selon les nécessités, les galets 3 sont répartis régulièrement ou non le long de la courbe de référence C.The fixed beam 6 can have, in particular, a general form of pseudo circular segment, which allows it to be used with different reference curves. This characteristic which allows a certain standardization is illustrated by FIG. 4 in which it can be seen that the same fixed beam 6 can relate to several - in fact three reference curves C1, C2, C3, etc. Depending on the requirements, the rollers 3 are distributed regularly or not along the reference curve C.

Selon une variante de réalisation possible, non représentée, les axes 3a des galets 3 sont montés fixes sur la poutre fixe 6. Dans ce cas, les galets 3 n'ont qu'une courbe enveloppe (tangente aux galets 3) unique.According to a possible alternative embodiment, not shown, the axes 3a of the rollers 3 are mounted fixed on the fixed beam 6. In this case, the rollers 3 have only a single envelope curve (tangent to the rollers 3).

Selon une autre variante de réalisation possible, représentée sur la figure 2, les axes 3a des galets 3 sont montés mobiles sur la poutre fixe 6. Ces galets 3 ou certains d'entre eux ont alors plusieurs courbes enveloppe possibles. A cet effet, les galets 3 peuvent être portés par des balanciers 8 articulés sur la poutre fixe 6 autour d'axes 8a, parallèles aux axes 3a. Dans une forme de réalisation possible, un balancier 8 supporte deux galets 3 placés respectivement à chacune de ses parties extrêmes 8b, l'axe d'articulation 8a du balancier 8 se trouvant dans sa partie médiane 8c. Cette disposition permet une certaine standardisation tout en assurant un minimum de contact entre le câble 1 et les galets 3, dans les différents états de charge possibles du câble 1.According to another possible alternative embodiment, shown in FIG. 2, the axes 3a of the rollers 3 are mounted mobile on the fixed beam 6. These rollers 3 or some of them then have several possible envelope curves. To this end, the rollers 3 can be carried by pendulums 8 articulated on the fixed beam 6 around axes 8a, parallel to the axes 3a. In one possible embodiment, a balance 8 supports two rollers 3 placed respectively at each of its end parts 8b, the hinge pin 8a of the balance 8 being in its middle part 8c. This arrangement allows a certain standardization while ensuring a minimum of contact between the cable 1 and the rollers 3, in the different possible states of charge of the cable 1.

Il est clair qu'un balancier 8 peut recevoir un nombre de galets différents. La poutre fixe 6 peut, de son côté, recevoir un nombre quelconque et approprié de galets 3 allant de quelques uns -huit par exemple- à plusieurs dizaines -une trentaine par exemple- la longueur de la poutre fixe 6 est donc adaptée en conséquence.It is clear that a balance 8 can receive a number of different rollers. The fixed beam 6 can, for its part, receive any suitable number of rollers 3 ranging from a few - eight for example - to several tens - thirty for example - the length of the fixed beam 6 is therefore adapted accordingly.

Dans le cas de plusieurs câbles 1 parallèles, il est prévu plusieurs poutres fixes 6 réunies par des entretoises ou une poutre fixe unique ayant en section droite transversale un profil en V (ou en V renversé).In the case of several parallel cables 1, there are provided several fixed beams 6 joined by spacers or a single fixed beam having in cross-section a V-shaped (or inverted V-shaped) profile.

L'installation peut comprendre, le cas échéant, des moyens formant butée limitant le pivotement des balanciers 8 ou encore des moyens classiques de rappel sollicitant les balanciers 8 vers leur position de référence.The installation may include, if necessary, means forming a stop limiting the pivoting of the pendulums 8 or even conventional return means urging the pendulums 8 to their reference position.

Sur la figure 5 est représenté -en tant que cas fictif et à titre seulement illustratif- le train de galets 3 de la figure 2 dans une configuration différente (respectivement à vide figure 5, et en charge figure 2). Certains ou tous les balanciers 8 se sont déplacés à pivotement autour de leurs axes 8a induisant une nouvelle courbe enveloppe -correspondant au cheminement du câble 1-.In FIG. 5 is shown - as a fictitious case and by way of illustration only - the roller train 3 of FIG. 2 in a different configuration (respectively when empty in FIG. 5, and when loaded in FIG. 2). Some or all of the pendulums 8 have pivoted around their axes 8a inducing a new envelope curve -corresponding to the routing of the cable 1-.

Dans cette situation, certains galets 3 sont en contact avec le câble 1 -et d'ailleurs avec une pression variable plus ou moins importante- alors que d'autres galets 3 sont inactifs car écartés du cable 1. Cette disposition est acceptée, en tant que contrepartie à l'absence de mouvement brusque et d'amplitude importante du câble 1.In this situation, some rollers 3 are in contact with the cable 1 - and moreover with a variable pressure more or less important - while other rollers 3 are inactive because they are spaced from the cable 1. This arrangement is accepted, as a counterpart to the absence of sudden movement and significant amplitude of the cable 1.

Claims (8)

1. Aerial-rope installation for transporting goods or persons, of the type having one or more carrying-hauling aerial ropes (1) extending between two end stations respectively for loading or embarking (2a) and unloading or disembarking (2b), possibly with one or more intermediate stations, the ropes being held and guided by support rollers and compression rollers (3) carried by one or more generally several pylons (4) which are distributed between the stations (2a) (2b) and with which are associated in fixed or disengageable manner one or more generally several carriers (5), in particular cabins, a pylon (4) having at least one fixed beam (6) carried by at least one support bracket (7), the rollers (3) being mounted on the beam (6), characterized in that the rollers (3) are mounted on the fixed beam (6) along an intermediate reference curve C between the various rope curves corresponding to the different loading states possible, this reference curve C being determined by calculation for each particular placement, the rollers (3) being mounted on the fixed beam (6) totally independently-individually or in groups-of the neighbouring rollers or groups of rollers (3), the spindle (3a) of each roller (3) being fixedly mounted on the beam (6) or else movably mounted on the beam (6) by way of a rocker (8) articulated on the beam (6), which has the function of determining at least partly the path or the limits of the path of the rope (1) with a view to preventing sudden displacement or displacement of large amplitude of the rope (1) when the carriers (5) pass at right angles to a pylon (4) and thus preventing a swinging movement of the carriers.
2. Installation according to Claim 1, characterized in that its load is concentrated, the distribution and capacity of the carriers (5) being such that the resulting load is on the one hand relatively large-in particular in the order of 1.5 to 2.5 tonnes per linear metre- and on the other hand concentrated over a limited length, in particular in the order of 3 to 6 metres.
3. Installation according to either of Claims 1 and 2, characterized in that the spindle (3a) of a roller (3) is carried by a rocker (8) articulatedly mounted on the fixed beam (6) about a spindle (8a) parallel to the spindle (3a) of the roller (3).
4. Installation according to Claim 3, characterized in that a rocker (8) has at least two rollers (3), in particular at each of its end parts (8b), the rocker (8) being articulated to the fixed beam (6) in its central part (8c).
5. Installation according to any one of Claims 1 to 4, characterized in that the reference curve C corresponds at least substantially to the state where the rope (1) undergoes maximum load.
6. Installation according to any one of Claims 1 to 5, characterized in that the rollers (3) are distributed regularly or otherwise along the reference curve C.
7. Installation according to any one of Claims 1 to 6, characterized in that the linear speed of the rope (1) is between 7 and 8 metres per second, in particular equal to or in the order of 7.5 metres per second.
8. Installation according to any one of Claims 2 to 7, characterized in that it has a plurality of-in particular three-cabins (5) following one another with immediate proximity and associated with one another.
