Definitions

  • the invention relates to an overhead cable-to-tractor transport installation extending between two end stations, comprising clamps with a pair of jaws, capable of gripping the cable to couple the clamp to the cable in line and to be open to uncouple the cable clamp in stations, seats or cabins, each suspended on a clamp, a transfer rail, which extends in the station to support the uncoupled cable clamp, a section d clutch where the rail is parallel to the cable and is arranged to introduce the cable between the jaws of the clamp at the entrance to the section and couple the clamp by closing the jaws to the cable at the exit of the section and a safety device , located on the clutch section, to detect faulty operation.
  • the safety device triggers the shutdown of the installation, in the event of an incident, in order to avoid leaving the station seat and / or coupling it to the cable.
  • the stop is not instantaneous and it is therefore necessary to provide a safety distance which contributes to the elongation of the station.
  • a particularly dangerous situation results from a closing of the clamp, the cable being outside the jaws, in particular at side of them. The fall of the seat or cabin is then inevitable, when the clamp leaves the transfer rail and safety measures are essential.
  • the present invention aims to improve the operating safety of such an installation by using simple means.
  • the installation according to the invention is characterized in that said safety device comprises a template, the passage section of which corresponds, apart from play, to the external section of the clamp and of the cable introduced between the jaws of the clamp, so as to allow free passage of the clamp towards the exit of the clutch section, when the cable is correctly inserted between the jaws and causing the clamp to jam in the jig, when the cable is outside the jaws, to prevent the clamp from advancing up to 'at the exit of the section.
  • the template in the form of a closed frame has a substantially horizontal or slightly concave base to constitute a cable catcher during a fall. or a lowering thereof, for example due to a failure of a support roller.
  • the template is advantageously mounted on slides, which extend parallel to the cable, and the braking means are incorporated or associated with these slides.
  • the cable remains in movement and it slides forcibly in the template, risking tearing everything out if the movement persists for a certain time.
  • the clamping of the clamp in the template is perceived by the usual safety systems, which control the stopping of the installation, in particular by the detector of excessive oscillations of the cable, due to shock or by the seat tracking controller or cabins, later called seats. Additional safety devices can be provided in order to react, for example during an untimely movement of the template and to stop the drive motor, with a lower response time.
  • a carrier-tractor cable 10 of a transport installation in particular of a gondola or a chairlift, extends in a closed loop between two stations, passing at the station exit by a section of clutch 11 where the seat 12, which circulates in the station while rolling on a rail 13, is re-coupled to the cable 10.
  • the seat 12 is carried by a hanger 14, the upper end 15 of which is articulated on the body of a clamp 16, equipped with a pair of jaws 17, capable of enclosing the cable 10, and rollers 18 for rolling on the rail 13.
  • a lever 19 controls the opening and closing of the clamp 16 and a spring 20 urges the jaw 17 in the cable clamping position 10.
  • the clamp 16 is uncoupled and it rolls at low speed on the transfer rail 13, being driven by friction wheels 21, staggered along the rail 13 and which engage a cross 22 secured to the clamp 16.
  • the cable 10 is t supported and guided in the clutch section 11 by support rollers 23, the path of the cable 10 being parallel to that of the rail 13 with a slight upward slope, to introduce the cable 10, which is below and outside the jaws 17 at the entrance to section 11, gradually between these jaws 17 during the movement of the clamp 16 and allow the clamp 16 to be coupled to the cable 10, at the outlet 24 of this section 11, by closing the jaws 17.
  • the clutch section 11 is equipped with usual safety devices, not shown, which verify in particular the path of the cable 10, the integrity of the clamp 16 and the correct routing of the seats 12. Such an installation is well known to specialists and it is unnecessary to describe it in more detail.
  • the template 25 is mounted on slides 27, parallel to the rail 13, which allow limited sliding of the template 25 in the direction of the outlet 24.
  • the slides 27 are carried by the framework of the station or directly by the rail 13.
  • Braking blocks 28 are associated with these slides 27 or with any other part of the template 25, to vigorously brake this sliding.
  • the internal contour 29 of the sheath 26 conforms with little play to the external contour of the jaws 17 and of the cable 10 introduced between these jaws 17 and the inlet of the sheath 26, which extends parallel to the cable 10, is flared.
  • the base 30 of the sleeve 26 forms a horizontal or concave seat, disposed slightly below the cable 10 and capable of holding or catching the latter in the event of a failure of a support element, in particular of a roller 23.
  • the clamp 16 is of course stopped, while the cable 10 is forcibly pulled in the sheath 26 until the installation drive motor stops.
  • This stopping is triggered by the usual safety systems, which detect the excessive oscillation of the cable 10, due to the shock or the interruption of the path of the seats 12.
  • An additional safety device can detect the sliding of the template 25 and cause the shutdown. After such a stop, it is obviously necessary to check the good condition of the installation and replace the template 25 in place.
  • the mechanical locking of the clamp 16 prevents the latter from exceeding a determined point if the cable 10 is not inserted between the jaws 17 and in any case reaching the output 24 of the clutch section 11.
  • the effort braking exerted on the template 25 and the stroke of this braking are determined to limit the swing amplitude of the seat 12 to an acceptable and non-dangerous value for the occupants.
  • the operation of the installation according to the invention follows from the preceding description and it suffices to note that such a safety device can be easily mounted on an existing installation.
  • the sheath 26 prevents any derailment of the clamp 16 and its length is sufficient to ensure in all cases the clamping of the clamp.
