Definitions

  • the invention relates to a cable holding device and installation for overhead cable transport comprising such a device.
  • the main constructive characteristic of this known device is that on the one hand the spacing of the rollers corresponding to the two cables and kept positively constant and equal to the spacing of the cables and that, on the other hand, the overall pivoting movements rollers (around the pivoting axis of the flat bars) corresponding to the two cables are made positively in perfect synchronism, that is to say that a symmetrical pivoting of the pendulums is imposed.
  • This positive maintenance of the spacing and of the synchonism as well as of the symmetry of the pivoting is obtained thanks to the rigid stirrup joining in a monobloc and undeformable assembly the rollers (or pk.s precisely their axes of rotation) located in correspondence and associated to the two cables.
  • the stirrup Given the passage to be left free between the cables for the carriage or the like carrying the vehicle, the stirrup has a general shape of an inverted U.
  • This known structure responds to the concerns of ensuring perfect symmetry and synchronism between the two cables and therefore of the members associated with them. If from a theoretical point of view this concern seems legitimate, it is not the same from a practical point of view.
  • these parameters can, in practice, vary widely from one cable to another on the same cross section, if only because the cable paths are distinct from each other (the paths being generally possibly uneven) with all the consequences which result therefrom. Under these conditions, maintaining synchronism or symmetry of movement between the pendulums or the rollers can in fact prove to be a particularly annoying drawback insofar as it generates additional stresses in the cable holding device.
  • the invention aims to remedy these drawbacks and to this end it proposes a device for holding the cables of an installation having one or more vehicles supported by at least two parallel carrying cables and tractors, of the type comprising, for each of the cables, one or generally several elementary pendulums, furnished with at least one roller with which the corresponding cable cooperates, this elementary pendulum being pivotally mounted about an axis orthogonal to the cables on support pendulums, themselves carried by a bearing structure, elementary pendulums, the rollers, the pendulums supporting the different cables being placed facing each other, characterized in that the facing elementary pendulums associated with the different cables are not mechanically connected together in order to form a monobloc assembly such that their symmetrical pivoting be imposed.
  • the device comprises means limiting the amplitude of the pivoting of the elementary pendulums around their pivot axis as well as means limiting the amplitude of the pivoting of the support pendulums around their pivot axis.
  • the invention aims to avoid completely subjecting each other the rollers associated with the different cables. These rollers have a certain freedom in their overall movements. However, this reciprocal travel is limited. Consequently, the stresses on the cables or their holding devices are better distributed.
  • the invention relates to a cable holding device 1 intended in particular for an overhead cable transport installation - in particular two parallel or substantially parallel carrying cables and tractors 1 a, 1 b.
  • the device has an overall symmetry with respect to a median plane P.
  • This plane is generally a vertical plane in the case of an overhead cable transport installation.
  • the device will be described in its generality without referring specifically to one cable or another, the corresponding reference then being devoid of index.
  • the corresponding reference will be followed by the index a or b, respectively.
  • the device comprises, for each of the cables 1, one or more generally several elementary pendulums 2 furnished with at least one roller 3 pivoting about its axis 4 and with which the corresponding cable 1 cooperates.
  • This elementary pendulum 2 is pivotally mounted around an axis 5 orthogonal to the cables 1 on support pendulums 6 themselves carried by a bearing structure 7.
  • the elementary pendulums 2, rollers 3, axis 4, axis 5, support pendulums 6, and components of the supporting structure 7 associated with the various cables 1, are placed facing each other since they are placed as a whole symmetrically with respect to the plane P.
  • the support pendulum 6 is also pivotally mounted on the supporting structure 7 around an axis 8 parallel to the axes 4 and 5.
  • an elementary balance 2 of a cable 1 comprises two rollers 3 placed in close proximity to each other, the axes 4 of these rollers being located at the two end parts 9 of the elementary balance 2.
  • a support pendulum 6 are associated with two elementary pendulums 2, the axes 5 being located at the end portions 10 of the support pendulum 6.
  • the two closest rollers 3 associated with the two elementary pendulums 2 are placed in close proximity to one another.
  • the supporting structure 7 associated with a cable 1 are associated with two support pendulums 6, the pins 8 being placed at the end portions 11 of this structure.
  • the closest rollers of the two support pendulums 6 are also placed in the immediate vicinity of one another.
  • the axes 5 and 8 are placed in the middle parts of the elementary balance 2 and of the support balance 6, respectively.
  • the rollers 3 are normally identical and consist of grooved pulleys.
  • the invention applies to the case of an elementary balance 2 furnished with a different number of rollers 3, to the case of a support balance 6 furnished with a different number of elementary balance 2 and to the case of a bearing structure 7 furnished with a different number of support pendulums 6.
  • the invention also applies to the case where the structure which has just been described (first pendulum mounted to pivot by its middle part to the end part of a second pendulum) and multiplied more significantly.
  • the rollers 3 are either support rollers, when the cables 1 are located above, or compression rollers, when the cables 1 are located below.
  • the supporting structure 7 is symmetrical with respect to the plane P, and external to the cable channel 1 and the rollers 3, the elementary pendulums 2, the supporting pendulums 6 are placed laterally, towards the outside of the supporting structure 7 therefore, or near or symmetrically on either side of the planes P A and P B parallel to the plane P and passing through the cables 1a, 1b respectively.
  • the structure 7 is central (not shown).
  • each elementary balance 2 associated with a cable 1 is in two parts 2 ′, 2 "placed respectively on either side of the rollers 3.
  • each balance associated with a cable 1 is also in two parts 6 ', 6 ", on either side of the rollers 3 and outside of the parts 2 ′ and 2" of the elementary pendulums 2.
  • the supporting structure 7 forms two lateral beams fixed to and carried by a super structure not shown in particular forming part of a pylon.
  • Each axis 8 is fixed and extends on either side of the supporting structure 7 in the direction of the planes Pa and Pb.
  • On the axis 8 are mounted the two parts 6 'and 6 "of a support pendulum 10 and this for each of the cables 1 a, 1 b.
  • the two parts 6 'and 6 are spaced transversely from one another to allow the accommodation between them of the parts 2" and 2 "of the two elementary pendulums 2 and of the rollers 3.
  • the elementary pendulums 2 in correspondence associated with the different cables are not mechanically connected together in order to form a one-piece assembly such that their symmetrical pivoting is imposed. This absence of direct and rigid mechanical connection is clearly visible in FIG. 1.
  • the corresponding support pendulums 6 associated with the different cables are not mechanically connected together in order to form a one-piece assembly such as their pivoting symmetrical be imposed. This characteristic is also clearly visible in FIG. 1.
  • means are provided limiting the amplitude of the pivoting of the elementary pendulums 2 about their pivot axis 5.
  • means are provided limiting the amplitude of the pivoting of the elementary pendulums 2 around their pivot axis 5 at a value between 0 °, terminal excluded, and 10 ° .
  • These means limiting the amplitude of the pivoting of the elementary pendulums 2 about their axis 5 are constituted for example by a central part 12 associated with / or constituted by the support balance 6 cooperating with a double lateral part 13 forming a fork associated with / or constituted by the support balance 6 or the elementary balance 2.
  • the central part 12 is constituted by one of the parts - in particular the internal part - of the balance 2 and the lateral double part 13 is constituted by an insert on the support balance 6.
  • This central part 12 and double lateral part 13 assembly is spaced from the axis 5 by a distance that is not too great so that the amplitude of the pivoting is sufficient, nor too low so that this amplitude is not too large and this with a clearance of the central part 12 in the double lateral part 13 limited.
  • the central part 12 and double lateral part 13 assembly is placed between the axis 5 of the elementary balance 2 and the axis 4 of one of the rollers 3 that it supports.
  • the central part 12 and double lateral part 13 assembly is placed from the axis 5 at about a third of the distance separating the axis 5 from the axis 4.
  • the clearance between the central part 12 and the part double lateral 13 is for example of the order of a few millimeters.
  • part 12, part 13 assembly is provided for each elementary balance 2.
  • this central part 12 and double lateral part 13 assembly is placed on the internal part of a pendulum 2, that is to say the part facing the bearing structure 7. Also, preferably, each central part 12, double lateral part 13 assembly is placed at the extended end part 14 of the part internal 6 'of the support balance 6.
  • means are provided limiting the amplitude of the pivoting of the support pendulums 6 about their pivot axis 8. These means limit the pivoting for example to a value between 0 ° terminal excluded and 10 ° .
