Abstract

The attachment hook consists of an attachment body (10) which extends transversely on one side of the cable (9), and carries a suspension link (11) to carry the load. The jaw for gripping the cable consists of a fixed jaw (13) carried by the body of the attachment, and a moving jaw (14), linked to the fixed jaw. A control lever (17) attached to the fixed jaw is used to control the opening and closing of the jaw. A pair of compression springs are arranged symmetrically on each side of a primary plane and assist the operating lever in its closed position. One of the stops for the springs is attached near the end of the control lever, opposite the mobile jaw. The other stop is attached near to the fixed jaw, so that the two springs extend in a second plane perpendicular to the first. The distance in the second plane between the points of attachment of the second stop is greater than that at the control lever end.

Description

L'invention est relative à une pince débrayable d'accouplement d'une charge à un câble porteur-tracteur d'une installation de transport à câble aérien, comprenant un corps de pince s'étendant transversalement d'un côté du câble, en position accouplée à ce dernier, et portant une articulation d'une suspente de support de la charge, une mâchoire de serrage du câble, constituée par un mors fixe porté par le corps de pince et un mors mobile articulé sur le mors fixe, un levier de commande, qui est solidaire du mors mobile et prolonge ce dernier en s'étendant et en se débattant dans un premier plan contenant le corps de pince, pour commander l'ouverture et la fermeture de la mâchoire, et une paire de ressorts de compression à boudin disposés symétriquement de part et d'autre dudit premier plan et sollicitant le levier de commande en position de fermeture de la mâchoire.The invention relates to a disengageable clamp for coupling a load to a carrier-tractor cable of an overhead cable transport installation, comprising a clamp body extending transversely on one side of the cable, in position coupled to the latter, and carrying an articulation of a load support hanger, a cable clamping jaw, constituted by a fixed jaw carried by the clamp body and a movable jaw articulated on the fixed jaw, a lever control, which is integral with the movable jaw and extends the latter by extending and struggling in a first plane containing the clamp body, to control the opening and closing of the jaw, and a pair of compression springs to rod placed symmetrically on either side of said first plane and urging the control lever in the closed position of the jaw.

Une pince connue du genre mentionné ( EP-A-0 056 919 ) est particulièrement simple et peut rester en ligne pendant la nuit sans risque de blocage par la glace ou le givre. Cette pince comporte des ressorts intercalés entre les extrémités, du côté opposé au mors fixe, du corps de pince et du levier de commande. Cette disposition implique une structure robuste et encombrante de la pince, adaptée aux efforts importants à transmettre.A known clamp of the kind mentioned (EP-A-0 056 919) is particularly simple and can remain in line overnight without risk of blockage by ice or frost. This clamp has springs interposed between the ends, on the side opposite the fixed jaw, of the clamp body and of the control lever. This arrangement implies a robust and bulky structure of the clamp, adapted to the large forces to be transmitted.

La présente invention a pour but de permettre la réalisation d'une pince débrayable de structure simple et compacte.The present invention aims to allow the realization of a disengageable clamp of simple and compact structure.

La pince selon l'invention est caractérisée en ce que l'un des bouts des ressorts est ancré au voisinage de l'extrémité du levier de commande, opposée au mors mobile, que l'autre bout des ressorts est ancré près du mors fixe, que les deux ressorts s'étendent dans un deuxième plan, qui est perpendiculaire au premier plan et est incliné par rapport au corps de pince et que la distance dans ledit deuxième plan entre les points d'ancrage des bouts des ressorts du côté du mors fixe est supérieure à celle du côté du levier de commande.The clamp according to the invention is characterized in that one of the ends of the springs is anchored in the vicinity of the end of the control lever, opposite the movable jaw, that the other end of the springs is anchored near the fixed jaw, that the two springs extend in a second plane, which is perpendicular to the first plane and is inclined relative to the clamp body and that the distance in said second plane between the points the ends of the springs on the side of the fixed jaw is greater than that on the side of the control lever.

Le point d'ancrage des ressorts est reporté près du mors fixe et de l'articulation de la suspente et il est facile de voir que les efforts sont concentrés dans cette zone qui est agencée en conséquence.The anchor point of the springs is transferred near the fixed jaw and the articulation of the hanger and it is easy to see that the forces are concentrated in this zone which is arranged accordingly.

Selon un développement de l'invention les deux ressorts sont ancrés du côté du mors fixe à une traverse, qui porte les galets de support et de guidage de la pince. La pince est désaccouplée du câble à l'entrée d'une station et les galets roulent sur un rail de transfert. Les galets et les points d'ancrage des ressorts sont au voisinage des extrémités de la traverse et celle-ci est intercalée entre le mors fixe et l'articulation de la suspente. La pince comporte avantageusement un troisième galet monté à rotation sur l'extrémité du corps de pince, opposée au mors fixe. Le levier de commande porte à son extrémité opposée au mors mobile un galet de commande, qui coopère à l'entrée d'une station avec un rail de commande de l'ouverture de la pince pour désaccoupler la pince du câble. D'une manière analogue un rail, disposé à la sortie, commande le réaccouplement de la pince au câble d'un manière bien connue des spécialistes.According to a development of the invention, the two springs are anchored on the side of the jaw fixed to a cross member, which carries the support and guide rollers of the clamp. The clamp is uncoupled from the cable at the entrance to a station and the rollers roll on a transfer rail. The rollers and the anchor points of the springs are in the vicinity of the ends of the cross member and the latter is interposed between the fixed jaw and the articulation of the hanger. The clamp advantageously comprises a third roller mounted for rotation on the end of the clamp body, opposite the fixed jaw. The control lever carries at its end opposite to the movable jaw a control roller, which cooperates at the entrance to a station with a control rail for opening the clamp to uncoupling the clamp from the cable. Similarly, a rail, disposed at the outlet, controls the re-coupling of the clamp to the cable in a manner well known to specialists.

La distance entre les points d'ancrage des ressorts, du côté du mors fixe, est supérieure au gabarit de l'articulation de la suspente, laquelle peut ainsi être adjacente à la traverse en étant encadrée des deux ressorts. Les points d'ancrage des ressorts du côté du mors fixe sont sensiblement au niveau du corps de pince et les ressorts s'étendent vers le haut au-dessus du corps de pince en étant doublement inclinés par rapport à ce dernier. Ces inclinaisons influencent l'action des ressorts sur le levier de commande et permettent une modulation des caractéristiques de ces ressorts.The distance between the anchoring points of the springs, on the side of the fixed jaw, is greater than the gauge of the articulation of the hanger, which can thus be adjacent to the cross member while being framed by the two springs. The anchoring points of the springs on the side of the fixed jaw are substantially at the level of the clamp body and the springs extend upwards above the clamp body while being doubly inclined relative to the latter. These inclinations influence the action of the springs on the control lever and allow modulation of the characteristics of these springs.

L'entraînement de la pince désaccouplée du câble dans les stations est de préférence réalisé par des trains de roues pneumatiques, qui engagent une piste de friction disposée au-dessus de la traverse qui porte les galets de support.The drive of the uncoupled clamp of the cable in the stations is preferably carried out by sets of wheels tires, which engage a friction track arranged above the cross member which carries the support rollers.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention donné à titre d'exemple et représenté aux dessins annexés, dans lesquels:

  • la figure 1 est une vue en élévation, partiellement en coupe, d'une pince selon l'invention, représentée en trait plein en position de fermeture et en pointillés en position d'ouverture;
  • la figure 2 est une vue en plan de la pince selon la figure 1.
Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention given by way of example and shown in the appended drawings, in which:
  • Figure 1 is an elevational view, partially in section, of a clamp according to the invention, shown in solid lines in the closed position and in dotted lines in the open position;
  • FIG. 2 is a plan view of the clamp according to FIG. 1.

Sur les figures une pince débrayable présente un corps allongé 10, qui s'étend, en position accouplée de la pince au câble 9, transversalement au câble. Le corps 10 porte une articulation 11 d'une suspente 12 et il est prolongé par une paire de mors 13,14 formant une mâchoire de serrage du câble 9, l'un 13 des mors étant fixe et l'autre mobile 14 étant articulé sur un axe 15 porté par le corps 10. En position de serrage du câble 9 par les mors 13,14, l'axe 15 s'étend parallèlement au-dessus du câble 9. Le mors mobile 14 est conformé à l'extrémité 16 d'un levier de commande 17, qui s'étend et peut se débattre, lors d'un pivotement sur l'axe 15, dans un premier plan contenant le corps de pince 10 et correspondant au plan de la figure 1. A l'extrémité 18, opposée au mors mobile 14, du levier 17 est fixé un axe 19 de rotation d'un galet de commande 20. Le corps de pince 10 porte trois galets 21,22,23 de support et de guidage de la pince désaccouplée du câble 9 et susceptibles de rouler sur des rails dans les stations. L'un 21 des galets est monté à rotation sur l'extrémité du corps de pince 10, opposée au mors fixe 13 et les deux autres 22,23 sont fixés aux extrémités 24,25 d'une traverse 26 portée par le corps de pince 10. La traverse 26 est intercalée entre le mors fixe 13 et l'articulation 11 et elle s'étend dans la direction du câble 9. Au-dessus de la traverse 26 est disposée une piste de friction 27, susceptible de coopérer avec des roues à pneumatique pour l'entraînement de la pince dans les stations. Une telle pince est bien connue et il est inutile de la décrire plus en détail.In the figures, a disengageable clamp has an elongated body 10, which extends, in the coupled position of the clamp to the cable 9, transversely to the cable. The body 10 carries an articulation 11 of a hanger 12 and it is extended by a pair of jaws 13,14 forming a cable clamping jaw 9, one of the jaws being fixed and the other movable 14 being articulated on an axis 15 carried by the body 10. In the cable 9 clamping position by the jaws 13,14, the axis 15 extends parallel above the cable 9. The movable jaw 14 is shaped at the end 16 d 'a control lever 17, which extends and can be struggled, during a pivoting on the axis 15, in a first plane containing the clamp body 10 and corresponding to the plane of Figure 1. At the end 18, opposite the movable jaw 14, of the lever 17 is fixed an axis 19 of rotation of a control roller 20. The clamp body 10 carries three rollers 21,22,23 for supporting and guiding the clamp uncoupled from the cable 9 and likely to roll on rails in stations. One 21 of the rollers is rotatably mounted on the end of the clamp body 10, opposite the fixed jaw 13 and the other two 22,23 are fixed to the ends 24,25 of a crosspiece 26 carried by the clamp body 10. The cross member 26 is interposed between the fixed jaw 13 and the articulation 11 and it extends in the direction of the cable 9. Above the cross member 26 is arranged a friction track 27, capable of cooperating with wheels pneumatic for the gripper drive in the stations. Such pliers are well known and there is no need to describe them in more detail.

Le levier de commande 17 est sollicité en position de serrage du câble 9, représentée en trait plein sur les figures, par une paire de ressorts de compression à boudin 28,29, intercalés entre le levier de commande 17 et le corps de pince 10. Les deux ressorts 28,29 sont disposés symétriquement de part et d'autre du premier plan, défini par le levier de commande 17 et le corps de pince 10 et ils s'étendent dans un deuxième plan perpendiculaire au premier et incliné par rapport au corps de pince 10. Les bouts supérieurs 30,31 des ressorts 28,29 sont ancrés par des articulations sphériques 37 à un bras transversal 32, fixé à l'extrémité 18 du levier de commande 17. D'une manière analogue les bouts inférieurs 33,34 des ressorts 28,29 sont ancrés au voisinage des extrémités 24,25 de la traverse 26 par des articulations sphériques 37 et des bras 35,36. Les points d'ancrage des bouts inférieurs 33,34 sont sensiblement au niveau du corps de pince 10 et leur écartement est suffisant pour libérer le gabarit de logement et de pivotement de la suspente 12 et de son articulation 11. L'écartement des points d'ancrage des bouts supérieurs 30,31 est notablement plus faible et il est facile de voir que les ressorts 28,29 sont à la fois inclinés dans le premier et dans le deuxième plan. Cette disposition oblique permet un rapprochement des parties actives de la pince soumises à d'importants efforts, en l'occurrence les mors 13,14, la suspente 12, la traverse 26 et les bouts inférieurs 33,34 des ressorts 28,29. La structure de la pince est particulièrement compacte, tout en conservant un dégagement des parties mobiles qui ne risquent pas d'être bloquées par la glace ou le givre. La double inclinaison des ressorts 28,29 modifie la composante de la force des ressorts agissant sur le levier de commande 17 et cette inclinaison varie avec le pivotement du levier de commande 17 de la manière représentée en pointillés sur les figures.The control lever 17 is biased in the cable tightening position 9, shown in solid lines in the figures, by a pair of compression coil springs 28, 29, interposed between the control lever 17 and the clamp body 10. The two springs 28, 29 are arranged symmetrically on either side of the first plane, defined by the control lever 17 and the gripper body 10, and they extend in a second plane perpendicular to the first and inclined relative to the body. of clamp 10. The upper ends 30, 31 of the springs 28, 29 are anchored by spherical articulations 37 to a transverse arm 32, fixed to the end 18 of the control lever 17. In a similar manner the lower ends 33, 34 springs 28, 29 are anchored in the vicinity of the ends 24, 25 of the cross-member 26 by spherical joints 37 and arms 35, 36. The anchoring points of the lower ends 33, 34 are substantially at the level of the clamp body 10 and their spacing is sufficient to free the housing and pivoting template of the hanger 12 and its articulation 11. The spacing of the points d anchoring of the upper ends 30, 31 is appreciably weaker and it is easy to see that the springs 28, 29 are both inclined in the first and in the second plane. This oblique arrangement allows a bringing together of the active parts of the clamp subjected to significant forces, in this case the jaws 13, 14, the hanger 12, the cross member 26 and the lower ends 33, 34 of the springs 28, 29. The structure of the clamp is particularly compact, while retaining a clearance from the moving parts which are not likely to be blocked by ice or frost. The double inclination of the springs 28, 29 modifies the component of the force of the springs acting on the control lever 17 and this inclination varies with the pivoting of the control lever 17 as shown in dotted lines in the figures.
