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 coupling pliers of a load to a carrier-tractor cable of a overhead cable transport, comprising a clamp body extending transversely on one side of the cable, in position coupled to the latter, and carrying a joint of a load support hanger, clamping jaw cable, consisting of 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 this last by stretching and wrestling in the foreground containing the clamp body, to control the opening and closure of the jaw, and a pair of springs of coil compression arranged symmetrically on both sides said foreground and urging the control lever in closing 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. Une pince correspondant au préambule de la Revendication 1 est connue également de EP-A-0 174 701 (LEITNER).A known clamp of the kind mentioned (EP-A-0 056 919) is particularly simple and can stay online overnight without risk of blockage by ice or frost. This clamp has springs interposed between the ends, on the side opposite the fixed jaw, the gripper body and the lever ordered. This arrangement implies a robust structure and bulky pliers, suitable for large forces to transmit. Pliers corresponding to the preamble of the Claim 1 is also known from EP-A-0 174 701 (LEITNER).
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 a disengageable pliers 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 near the end of the control lever, opposite the movable jaw, that the other end springs is anchored near the fixed jaw, that the two springs extend in a second plane, which is perpendicular to the foreground and is tilted relative to the clamp body and that the distance in said second plane between the points of 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 carried near the fixed jaw and the hanger joint and it's easy to see that efforts are concentrated in this area which is arranged Consequently.
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 crosspiece, which carries the support and guide rollers for the gripper. The clamp is uncoupled from the cable at the entrance to a station and the rollers roll on a transfer rail. Pebbles and dots anchor springs are near the ends of the crosspiece and this is interposed between the fixed jaw and the articulation of the line. The clamp has advantageously a third roller mounted for rotation on the end of the clamp body, opposite the fixed jaw. The lever control door at its end opposite the movable jaw a control roller, which cooperates at the entrance to a station with a clamp opening control rail for uncoupling the cable clamp. In a similar way a rail, arranged at the output, controls re-coupling of the clamp to the cable of a way 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 spring anchor points on the side of the fixed jaw, is greater than the size of the joint of the line, which can thus be adjacent to the cross member being framed by two springs. The anchor points of springs on the side of the fixed jaw are substantially at the level of the clamp body and springs extend up above of the gripper body being doubly inclined by compared to the latter. These inclinations influence the action of springs on the control lever and allow modulation characteristics of these springs.
L'entraínement 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 cable clamp in the stations is preferably carried out by wheel trains tires, which engage a friction track arranged above of the crosspiece 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:
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'entraínement 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
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
