Description

       

  La présente invention est relative à une installation de transport  aérien par téléphérique qui est caractérisée en ce qu'elle comporte deux câbles porteurs et tracteurs sans fin passant sur des poulies de renvoi aux extrémités du téléphérique et auxquels sont suspendues des 'bennes de transport en forme d' auges accouplées entre elles au moyen de tiges*. transversales fixées à ces câbles.

  
Une forme d'exécution de l'invention est représentée à titre d'exemple sur le dessin annexé.

  
La figure 1 est une vue de côté d'une section de l'installation avec station de chargement côté montagne;  La figure 2 est une vue analogue d'une autre section de l'installation avec station de déchargement côté vallée; La figure 3 est une coupe longitudinale à plus grande échelle d'un tronçon du téléphérique proprement dit; La figure 4 est une vue en plan correspondant à la figure 

  
Les figures 5 et 6 montrent à une échelle encore plus grande des détails de construction de ce téléphérique;

  
La figure-7 montre en coupe un poste d'inversion du téléphérique et

(voir fig. 5). Les brides entourent le câble a ou le &#65533;âble b et sont assujetties aux endroits de fixation par serrage des vis e. Pour empêcher'que les brides ne glissent dans la direction opposée à celle du déplacement du téléphérique, une douille f (fig.6) remplissant les fonctions d'une butée peut être aménagée derrière les brides sur le câblé considéré; cette douille présente un alésage conique dans lequel -s'engage un manchon de serrage fendu longitudinalement qui entoure étroitement le câble et présente une surface extérieure conique correspondant à la surface de l'alésage.

   Le serrage exercé par le manchon de calage g sur le câblé est d'autant plus grand que la pression des brides considérées sur la douille f est plus élevée, ce qui a pour effet d'éviter un glissement dans toutes les circonstances. 

  
La fixation.des tiges transversales aux câbles peut toutefois se  faire au moyen d'extrémités .-établies d'une autre manière, comme c'est représenté pour les tiges transversales c à droite sur la figure 4. Les extrémités des ti-

Les figures 8 et 9 montrent deux formes d'exécution différentes d' une griffe serre-câble. Les deux demi-spires sont désignées par dl et d . Alors que celles-ci dans le cas de la griffe:-suivant la figure 9 constituent ensemble une spire continue, dans la forme d'exécution suivant la figure 8 elles sont constituées chacune par un coude formé d'un fer plat recourbé sous forme semi-circulaire tantôt vers le haut tantôt vers le bas, ces coudes étant reliés



  The present invention relates to an air transport installation by cable car which is characterized in that it comprises two endless carrying cables and tractors passing over return pulleys at the ends of the cable car and from which are suspended shaped transport buckets. of troughs coupled together by means of rods *. transverse cables attached to these cables.

  
One embodiment of the invention is shown by way of example in the accompanying drawing.

  
FIG. 1 is a side view of a section of the installation with a loading station on the mountain side; FIG. 2 is a similar view of another section of the installation with an unloading station on the valley side; FIG. 3 is a longitudinal section on a larger scale of a section of the cable car proper; Figure 4 is a plan view corresponding to Figure

  
Figures 5 and 6 show on an even larger scale construction details of this cable car;

(see fig. 5). The clamps surround the cable a or the cable b and are secured to the fixing places by tightening the screws e. To prevent the flanges from sliding in the opposite direction to that of the movement of the cable car, a socket f (fig.6) fulfilling the functions of a stop can be fitted behind the flanges on the cable in question; this sleeve has a tapered bore in which engages a longitudinally split adapter sleeve which closely surrounds the cable and has a tapered outer surface corresponding to the surface of the bore.

   The tightening exerted by the setting sleeve g on the cable is all the greater as the pressure of the flanges considered on the sleeve f is higher, which has the effect of preventing slippage in all circumstances.

  
The fixing of the transverse rods to the cables can however be done by means of ends established in another way, as is shown for the transverse rods c on the right in figure 4. The ends of the rods

CLAIMS.

l. Cable car transport installation, characterized in that it comprises two endless carrying cables and tractors passing at the ends of the cable car on return rollers and from which are suspended trough-shaped transport buckets, coupled to each other by means of rods trans-

2. Cable car transport installation according to revendicatioi 1, characterized in, that the transverse rods are fixed to the cables using

stems.

3. Cable car transport installation according to claim 1; characterized in that the ends of the transverse rods are provided with two double bent cable clamps, arranged symmetrically with respect to the axis of the rod, which, when the conveyor buckets are suspended, extend in the direction of the length of the cable and surround the latter approximately by a turn, each cable clamping claw being established in such a way that each of the half-turns exerts a pressure on the cable under prestressing.

4. Cable car transport installation. Following claim 3, characterized in that the cable clamps each consist of

'semicircular shape, these elbows being interconnected by a bridge extending

approximately parallel to the longitudinal axis of the claw.

Cable car transport installation according to claims 1 to 4, characterized in that a sliding of the transverse rods relative to the cable in the direction opposite to that of the movement of the latter is avoided because a Tapered tightening sleeve tightly surrounding the cable is placed behind the cross rod in question and engages in a socket provided with a corresponding tapered bore.

6. Installation de-transport by cable car according to claim 1, characterized in that the \ transporters have at the upper part at their front ends of the legs extending in the longitudinal direction: of the cable car and provided with slots or slides, the corresponding legs of two successive buckets overlapping each other and the transverse rods passing through these slots or slides.
