Definitions

  • the invention relates to a mechanical device for adjusting a supporting rocker and guiding an aerial cable of a mechanical lift installation, said rocker being provided with rotating rollers for guiding the cable rotatably mounted on a chassis-carrier according to parallel axes of rotation staggered along the carrier frame in a longitudinal direction of the balance parallel to the direction of the cable, said carrier frame comprising a shoe fixed by clamping means to a bracket of a pylon of the installation in a position where an upper face of the shoe is facing a lower face of the bracket.
  • Such a pendulum is described for example in the document FR 2 801 267 .
  • the aerial cable is guided and maintained at each pylon by a lower beam with rotating rollers for supporting and guiding the cable when it is traveling and / or by a beam greater than rotating rollers for compression and guidance.
  • a mixed balance includes both a lower balance and an upper balance.
  • the pylons are distributed between the departure and arrival stations of the installation. Seats and / or cabins are fixed to the cable by fixed or disengageable gripping clamps.
  • the rotary rollers of the beam are generally associated in pairs by being mounted at the ends of primary beams, articulated in their middle part at the ends of secondary beams, themselves mounted in the same way on tertiary beams, and so on according to the number of pebbles.
  • the last beam is articulated in its middle part on a hoof attached to a pole of the pylon.
  • the assembly formed by the elementary beams (primary, secondary, tertiary etc ...) and the shoe is a chassis-carrier balance. In this way, the rollers of the balance are rotatably mounted on the carrier frame along parallel axes of rotation staggered along the carrier frame in a longitudinal direction of the balance which is substantially parallel to the direction of the cable.
  • the lack of inclination of the rollers relative to a vertical plane is a determining factor in terms of maintenance and safety of the balance and more generally of the installation. Indeed, a rocker in which the rollers have an inclination causes premature wear of the cable, all of the rollers of the balance wheel, particularly at the level of the bandages, and detachable clips of the vehicles. Such a defect may also have the consequence of causing the horizontality of vehicles suspended near the rollers to lose their level.
  • the object of the invention is to provide a mechanical device for adjusting a support beam and guiding an aerial cable of a mechanical lift installation which makes the adjustment more reliable while reducing the associated costs.
  • the device according to the invention is remarkable in that it comprises means for adjusting the inclination, obtained after clamping, of the bracket relative to the shoe in a lateral direction oriented parallel to the axes of rotation of the rollers.
  • such adjustment means allow to adjust in situ the inclination that the gallows has, after tightening, relative to the shoe (or vice versa) to make the balance wheels perfectly vertical.
  • proper handling of the adjustment means ensures that after adjustment of the balance (and after clamping the shoe against the stem), there is no vertical defect of the balance wheels. The reliability of the adjustment of the balance is thus reinforced.
  • the actual function of the adjusting means that is to say ensuring an adjustment of the lateral inclination that the bracket has with respect to the shoe (or conversely) after tightening, allows the adjustment means to be identical for all the stems where such adjustment is necessary.
  • Such an advantage makes possible the standardized manufacture of the adjustment means. The result is lower production costs.
  • the adjustment means comprise a first spacer of fixed height interposed between a first zone of the upper face of the shoe and the underside of the bracket and a second spacer of variable height interposed between the lower face of the gallows and a second zone of the upper face of the shoe, the second zone being offset relative to the first zone in the lateral direction.
  • the adjustment of the final lateral inclination after tightening is practiced very simply, by adjusting the length of the second spacer.
  • the figures 1 and 2 illustrate two rotary rollers 10a, 10b of a rocker supporting and guiding an aerial cable of a lift installation.
  • the rotary roller 10a is mounted for free rotation at one end of a first primary beam 11a
  • the second roller 10b is mounted for free rotation at one end of a second primary beam 11b aligned with the first primary beam 11a.
  • the rollers 10a, 10b are therefore rotatably mounted on the primary beams 11a, 11b of the rocker arm along parallel axes of rotation staggered along a longitudinal direction D1 (see arrow on FIG. figure 2 ) of the balance which is parallel to the direction of the cable.
  • the end of the first primary beam 11a carrying the first roller 10a is longitudinally opposite the end of the second primary beam 11b carrying the roller 10b.
  • the rollers 10a, 10b are longitudinally adjacent, although they are mounted on different primary beams 11a, 11b.
  • Each primary beam 11a, 11b is articulated, in its median part, at the end of a secondary beam 12.
  • the axes of rotation of the rollers 10a, 10b on the primary beams 11a, 11b, as well as the axes of articulation of the primary beams 11a, 11b on the secondary beam 12, are all parallel to each other in a lateral direction D2 of the pendulum (see arrow on the figure 1 ).
  • the lateral direction D2 is therefore oriented parallel to the axes of rotation of the rollers 10a, 10b.
  • the primary beams 11a, 11b are arranged on one side of the rollers 10a, 10b while the secondary beam 12 is placed on the other side.
  • the side comprising the primary beams 11a, 11b corresponds to the side outside of the beam and the side comprising the secondary beam 12 corresponds to the inner side of the balance.
  • the rocker arm is equipped, on the outside, with several rope catches 13 in case of derailment of the cable, and on the inside, of several anti-derailment stops 14.
  • a cable catcher 13 and an anti-derailment stopper 14 are associated with a pair of rollers mounted on a primary beam 11a, 11b.
  • the balance is fixed to the top of a tower of the lift installation, more precisely to the end of a tubular bracket 15 of square section whose main axis P is substantially horizontal.
  • the bracket 15 comprises an upper face 16 and a lower face 17, connected by two lateral faces 18, 19.
  • the shoe 20 For its attachment to the bracket 15, the balance has, on the inner side, a shoe 20 interposed between the secondary beam 12 and the bracket 15.

  • the secondary beam 12 is mounted in its central part to pivot on the shoe 20. This assembly is performed using a pivot shaft 28, parallel to the lateral direction D2 of the balance, connecting the two longitudinal flanges 26 , 27 and attached to them.
  • Each flange 26, 27 comprises, in its portion opposite the base 21, a through hole for the passage of one end of the pivot shaft 28.
  • the articulation of the beam secondary 12 on one end of the pivot shaft 28 can be obtained by any suitable means.
  • the attachment of the pivot shaft 28 to the shoe 20 is carried out at the opposite end of the pivot shaft 28, for example by means of a clamping clamp 29 integral with the longitudinal flange 27 and capable of exerting a radial clamping of the pivot shaft 28.
  • the clamping clamp 29 comprises a U-shaped clamping element whose branches are provided with a thread at their ends. Each of the threads cooperates with a screw nut 30.
  • the pivot shaft 28 passes through the U-shaped clamping element, the branches of which pass through the flange 27 through passage orifices arranged in a horizontal shelf of the flange.
  • Each screw nut 30 is screwed onto the part of a branch of the clamping element which protrudes from the through-holes of the flange 27.
  • the shoe 20 and the secondary beam 12 are mounted to pivot freely relative to each other.
  • the relative orientation of the secondary beam 12 relative to the shoe 20 is variable in a plane perpendicular to the lateral direction D2.

  • the angle formed by the longitudinal direction D1 (which is associated with the secondary beam 12) relative to the base 21 and the side wings 22, 23 is variable.
  • the assembly constituted by the elementary beams (primary 11a, 11b and secondary 12) and by the shoe 20 forms the frame-carrier balance.
  • the set of rollers (in variable number as a function of the number of elementary beams) of the balance are rotatably mounted on the carrier frame along parallel axes of rotation staggered along the frame- carrier in the longitudinal direction D1 of the balance.

  • This position of the lateral flanges 22, 23 on either side of the bracket 15 in the longitudinal direction D1 makes it possible to avoid the rotation of the shoe 20 relative to the bracket 15 about an axis parallel to the lateral direction D2.
  • the gap between a lateral flange 22, 23 and the corresponding lateral face 18, 19 is adjusted by means of an adjusting screw 35 mounted helically on the lateral flange 22, 23 and whose end bears against the lateral face 18, 19.

Regardless, the rest of the description could be adapted to a support and guide beam of the upper type which would be provided with rotary rollers for compressing and guiding the cable.
  • the main axis P of the bracket 15 may have a horizontal defect.
