Abstract

The safety mechanism consists of two or more retaining members (3, 4) fixed to a common support that can be moved between at least two positions. Between the positions at least one of the retaining members extends in line with one side of the guide pulley (14), with one retaining member being replaced by another as the pulley passes a cable fixing (16). Once past, the retaining members are returned to their initial position by a spring (5).

Description

La présente invention se rapporte à un dispositif de sécurité, destiné à empêcher un câble de traction et/ou de suspension d'un système de transport à entraínement et suspension par câble de sortir d'une poulie de guidage et de suspension.The present invention relates to a security device, intended to prevent a traction and / or suspension cable of a transport system with drive and suspension by cable out of a guide and suspension pulley.

Un des risques majeurs lié aux systèmes de transport à suspension et entraínement par câble est celui de la sortie latérale du câble de traction et/ou de suspension des poulies de guidage qui sont généralement disposées en batteries. Une des joues de ces poulies est généralement adjacente à un rail fixe qui empêche le câble de sortir des gorges respectives des poulies, tandis que l'autre joue est dégagée latéralement pour permettre le passage des moyens d'accrochage du véhicule suspendu au câble, de sorte que ce dernier, n'étant pas retenu, peut sortir latéralement de la gorge de la poulie d'un côté de celle-ci. La sortie du câble d'une poulie entraíne la sortie de ce câble de toutes les poulies d'une batterie de poulies et peut avoir des conséquences dramatiques.One of the major risks linked to transport systems suspension and drive by cable is that of the output side of the traction and / or pulley suspension cable which are generally arranged in batteries. A cheeks of these pulleys is generally adjacent to a rail fixed which prevents the cable from coming out of the respective grooves of the pulleys, while the other cheek is released laterally for allow the suspension means of the suspended vehicle to pass to the cable, so that the latter, not being retained, can come out laterally from the pulley groove on one side of it. The output of the cable from a pulley causes the output of this cable from all the pulleys of a pulley battery and can have dramatic consequences.

Le but de la présente invention est d'apporter une solution permettant d'éliminer, au moins en partie, ce risque.The purpose of the present invention is to provide a solution allowing this risk to be eliminated, at least in part.

A cet effet, la présente invention a pour objet un dispositif de sécurité, destiné à empêcher un câble de traction et/ou de suspension d'un système de transport à entraínement et suspension par câble de sortir d'une poulie de guidage et de suspension, tel que défini par la revendication 1. D'autres particularités de ce dispositif sont décrites dans la description qui va suivre et font l'objet des revendications dépendantes.To this end, the subject of the present invention is a device safety device, intended to prevent a traction cable and / or suspension of a driven transport system and cable suspension from a guide pulley and suspension, as defined by claim 1. Others peculiarities of this device are described in the description which will follow and are the subject of the dependent claims.

Les avantages de la solution proposée résident dans sa fiabilité et dans sa simplicité. Un autre avantage important de ce dispositif vient du fait qu'il peut non seulement équiper les nouvelles installations, mais qu'il peut aussi être monté sur les installations existantes, ce qui donne aussi la possibilité d'améliorer la sécurité de ces installations.The advantages of the proposed solution lie in its reliability and simplicity. Another important advantage of this device comes from the fact that it can not only equip new installations, but can also be installed on existing installations, which also gives the possibility improve the security of these facilities.

    • The appended drawing illustrates, schematically and by way of example, an embodiment of the security device which is the subject of the present invention.
  • Figure 1 is a perspective view of this device;
  • Figure 2 is a sectional view along II-II of Figure 1;

    • Le dispositif de sécurité illustré par les figures 1 à 3 comporte un bâti vertical 1 à la partie supérieure duquel un arbre 2 est monté pivotant autour d'un axe horizontal. Cet arbre 2 porte, d'un côté du bâti vertical 1, deux bras de retenue radiaux 3, 4, formant un angle d'à peu près 90° entre eux et de l'autre côté du bâti vertical 1, une came circulaire 5, contre laquelle un galet palpeur 6 est pressé en direction de l'axe de pivotement de l'arbre 2, par un ressort 7. Le galet palpeur 6 est lui-même monté pivotant autour d'une tige 8 d'axe parallèle à celui de l'arbre 2 et solidaire de l'extrémité d'un coulisseau 9 monté coulissant dans un carter 11, fixé au bâti vertical 1 par des vis 12.The safety device illustrated in Figures 1 to 3 has a vertical frame 1 at the top of which a shaft 2 is pivotally mounted about a horizontal axis. This shaft 2 door, on one side of the vertical frame 1, two arms of radial retainers 3, 4, forming an angle of approximately 90 ° between them and on the other side of the vertical frame 1, a circular cam 5, against which a feeler roller 6 is pressed in the direction of the pivot axis of the shaft 2, by a spring 7. The roller probe 6 is itself pivotally mounted around a rod 8 with an axis parallel to that of shaft 2 and integral with the end of a slide 9 mounted sliding in a casing 11, fixed to the frame vertical 1 by screws 12.

    Comme on le voit en particulier sur la figure 1, le carter 11 a la forme d'un parallélépipéde rectangle creux constitué par plusieurs plaques 11b assemblées par des vis 11a. Le ressort 7 est disposé entre le fond de ce carter 11 et une douille 13 fixée dans le coulisseau 9. La figure 3 illustre la came circulaire 5 dans la position stable de l'arbre de pivotement 2 et des bras 3 et 4, correspondant à la position des bras illustrée par les figures 1, 4 et 6. Comme on le remarque sur la figure 3, cette position stable correspond à l'endroit où la came circulaire 5 présente une courbure concave 5a, dont le rayon correspond à celui du galet palpeur 6. De part et d'autre de cette partie concave 5a, la came circulaire comporte deux courbes convexes 5b symétriques par rapport à une ligne passant par l'axe de l'arbre de pivotement 2 et le milieu de la courbure concave 5a. La distance séparant chacune de ces courbures convexes 5b de l'axe de pivotement de l'arbre de pivotement 2 croit en s'éloignant de la courbure concave 5a, de sorte que la pression exercé sur cette came circulaire 5 par le ressort 7 par l'intermédiaire du galet palpeur 6 crée sur cette came circulaire 5 un couple tendant à la ramener constamment dans la position illustrée par la figure 3, dès qu'elle est écartée angulairement de cette position stable.As seen in particular in Figure 1, the housing 11 has the shape of a hollow rectangular parallelepiped constituted by several plates 11b assembled by screws 11a. The spring 7 is disposed between the bottom of this casing 11 and a socket 13 fixed in the slide 9. Figure 3 illustrates the cam circular 5 in the stable position of the pivot shaft 2 and arms 3 and 4, corresponding to the position of the arms illustrated by Figures 1, 4 and 6. As can be seen in the Figure 3, this stable position corresponds to the place where the circular cam 5 has a concave curvature 5a, the radius corresponds to that of the feeler roller 6. On both sides of this concave part 5a, the circular cam has two convex curves 5b symmetrical about a passing line by the axis of the pivot shaft 2 and the middle of the concave curvature 5a. The distance between each of these convex curvatures 5b of the pivot axis of the shaft of pivot 2 grows away from the concave curvature 5a, so that the pressure exerted on this circular cam 5 by the spring 7 by means of the feeler roller 6 created on this circular cam 5 a torque tending to bring it constantly in the position illustrated in Figure 3, as soon as it is angularly moved away from this stable position.

    Comme on le remarque sur la figure 2, chaque bras de retenue radial 3, 4, (seul le bras 3 est représenté sur cette figure 2) comporte un noyau cylindrique 3a fixé à un moyeu 2a solidaire de l'arbre 2 et un élément tubulaire recouvert d'élastomère 3b est monté pour tourner librement autour du noyau cylindrique 3a. Cet élément tubulaire 3b est retenu axialement sur le noyau cylindrique 3a par un organe de retenue 3c maintenu par une vis 3d.As seen in Figure 2, each retaining arm radial 3, 4, (only arm 3 is shown in this figure 2) has a cylindrical core 3a fixed to a hub 2a integral with shaft 2 and a tubular element covered with elastomer 3b is mounted to rotate freely around the core cylindrical 3a. This tubular element 3b is retained axially on the cylindrical core 3a by a retaining member 3c maintained by a 3d screw.

    La figure 4 illustre le dispositif de sécurité décrit ci-dessus associé à une chape de poulies 13 portant deux paires de poulies de guidage 14, dont seule une paire est représentée, ainsi qu'un câble de traction et/ou de suspension 15, auquel est accroché un organe de fixation 16 d'un dispositif de transport (non représenté). Ce dispositif de transport peut être de n'importe quel type à entraínement et à suspension par câble, tel qu'un remonte-pente, un télésiège, une télécabine, un téléphérique, qui est entraíné par le câble 15 dans le sens de la flèche F. Figure 4 illustrates the safety device described above associated with a yoke of pulleys 13 carrying two pairs of guide pulleys 14, of which only one pair is shown, as well as a traction and / or suspension cable 15, to which is attached a fixing member 16 of a transport (not shown). This transport device can be of any type with drive and suspension by cable, such as a ski lift, chairlift, gondola, a cable car, which is driven by cable 15 in the direction of arrow F.

    La figure 4 montre cet organe de fixation 16 situé en amont du bras de retenue radial 3. Dans cette position, ce bras 3 est adjacent à une joue de la première poulie 14, empêchant ainsi toute sortie latérale du câble 15. La partie tubulaire 3b de ce bras de retenue radial 3 avec son revêtement élastomère lui permet d'être entraíné en rotation autour du noyau 3a par contact avec la joue de la poulie 14.FIG. 4 shows this fixing member 16 located at upstream of the radial retaining arm 3. In this position, this arm 3 is adjacent to a cheek of the first pulley 14, preventing thus any lateral outlet of the cable 15. The tubular part 3b of this radial retaining arm 3 with its elastomeric coating allows it to be rotated around the core 3a by contact with the pulley cheek 14.

    Lorsque l'organe de fixation 16 rencontre la bras radial 3 comme illustré par la figure 5, il le fait pivoter dans le sens inverse de celui des aiguilles d'une montre, en même temps que le bras 4, à l'encontre du couple exercé par le ressort 7 sur la came circulaire 5. Pendant un certain temps, les deux bras 3, 4 empêchent le câble de sortir latéralement des poulies. Ensuite, les bras 3 et 4 continuent de pivoter dans le même sens jusqu'à ce que l'organe de fixation 16 quitte l'extrémité du bras radial 3. A la fin de ce mouvement de pivotement des bras 3, 4, seul ce dernier se trouve en position d'empêcher le câble de sortir latéralement des poulies 14.When the fixing member 16 meets the radial arm 3 as illustrated in figure 5, it rotates it in the direction opposite to that of clockwise, at the same time as arm 4, against the torque exerted by spring 7 on the circular cam 5. For a while, the two arms 3, 4 prevent the cable from coming out laterally from the pulleys. Then, arms 3 and 4 continue to rotate in the same direction until the fixing member 16 leaves the end of the radial arm 3. At the end of this pivoting movement of the arms 3, 4, only the latter is in a position to prevent the cable laterally out of the pulleys 14.

    Lorsque l'extrémité du bras radial 3 quitte l'organe de fixation 16, le couple exercé sur la came circulaire 5 par le galet palpeur 6 et le ressort 7 ramène immédiatement les bras radiaux de retenue 3, 4 dans une position déterminée, illustrée par la figure 6 et correspondant à la position d'équilibre de la came circulaire 5, illustrée par la figure 3.When the end of the radial arm 3 leaves the attachment 16, the torque exerted on the circular cam 5 by the feeler roller 6 and the spring 7 immediately brings the arms back retaining radials 3, 4 in a determined position, illustrated by Figure 6 and corresponding to the equilibrium position of the circular cam 5, illustrated in FIG. 3.

    Ainsi, comme on peut s'en rendre compte de la description et des dessins qui l'accompagne, étant donné que la trajectoire décrite par les bras de retenue radiaux 3, 4 se situe dans un plan adjacent à la joue d'une poulie 14 opposée à celle tournée vers le bâti 1 et donc aussi adjacent à la trajectoire du câble 15, quelle que soit la position angulaire de ces bras 3, 4 au cours du passage d'un organe de fixation 16, il y a constamment au moins un bras radial de retenue 3, 4 dont une partie se situe à un niveau inférieur à celui du câble 15, retenant ainsi celui-ci latéralement. De ce fait, le dispositif de sécurité selon l'invention est constamment en action, même pendant le passage de l'organe de fixation 16 d'un véhicule au câble.So, as we can see from the description and accompanying drawings, given that the trajectory described by the radial retaining arms 3, 4 is located in a plane adjacent to the cheek of a pulley 14 opposite to that turned towards frame 1 and therefore also adjacent to the cable path 15, whatever the angular position of these arms 3, 4 at during the passage of a fastener 16, there is constantly at least one radial retaining arm 3, 4 of which a part is located at a level lower than that of cable 15, thus retaining this laterally. As a result, the safety device according to the invention is constantly in action, even during passage of the fastening member 16 of a vehicle to the cable.

    Bien entendu, la forme d'exécution décrite ici à titre d'exemple peut subir de nombreuses modifications sans sortir du cadre de la présente invention. Les moyens de rappel élastiques pourraient aussi être par exemple formés par un ressort spiral pré-armé dont une extrémité serait solidaire du bâti 1 et l'autre de l'arbre 2. On pourrait aussi imaginer un ressort de flexion pré-armé portant le galet palpeur 6 et dont les extrémités respectives seraient solidaires des deux bras de retenues 3, 4. On pourrait aussi utiliser une butée pour définir la position stable du dispositif de retenue, sans sortir du cadre des revendications.Of course, the embodiment described here under example can undergo many modifications without leaving the part of the present invention. Elastic return means could also be for example formed by a spiral spring pre-armed, one end of which is secured to frame 1 and the other of the tree 2. One could also imagine a spring of pre-armed flexion carrying the feeler roller 6 and the respective ends would be integral with the two arms of retained 3, 4. We could also use a stop to define the stable position of the retainer, without leaving the scope of claims.
