Definitions

  • the subject of the invention is a load bearing system, an installation comprising such a system and a method of mounting such a system.
  • This invention is more particularly intended for installations of the type cable cars or chairlifts.
  • the vehicle drives on a path of bearing which ensures its sustenance.
  • This raceway which sometimes also serves as a guide, is mounted rigidly on the load-bearing structures of the station so as to ensure the transmission of lift and guide forces.
  • the running rail In addition, in conventional running rails, the running rail must be adjusted according to the construction tolerances of the supporting structure. Of more, it is difficult to be able to adapt different forms of path bearing on the same load-bearing structure, these different shapes being able to match different vehicles.
  • the invention aims to overcome these drawbacks and proposes a rolling system to limit or even eliminate the vibrations and noise generated by the vehicle, to be able to use different raceways for a same load-bearing structure, and to be able to overcome the tolerances of construction.
  • the subject of the invention is, according to a first aspect, a system of bearing for a conveying installation, intended for support and rolling of a mobile load with respect to a fixed supporting structure, the system comprising at least one running rail arranged on a certain length of the supporting structure, the rail and the supporting structure being separated by a space, the system comprising support means and cushioning intended to be placed in the space between the rail and the structure load-bearing so that the rail is not rigidly and fixedly linked directly on the supporting structure, said means being flexible enough to absorb the noise and vibrations generated by the rolling of the load, and rigid enough to withstand the mechanical stresses applied to the rail.
  • the running rail has a straight cross section a general form of U, or V.
  • the support structure comprises a receptacle extending in the direction of the rail, the support and damping means being of a material at least partially filling the space between the rail and the supporting structure, the width of the receptacle being greater than the width of the rail, so that different rails can be used for the same structure carrier.
  • the receptacle has in cross section a general shape of U or V, complementary to that of the rail.
  • the damping means comprise a material cushioning cast in place, occupying the space between the rail and the receptacle carrier.
  • the material is an elastomer, a foam, a thermosetting plastic or the like.
  • the damping means comprise a seal extruded able to receive at least one rail mounting key.
  • the damping means comprise at at least one part in an intermediate assembly including absorbent elements vibration and noise.
  • the intermediate parts include studs elastics spaced along the raceway.
  • the running rail comprises, according to one embodiment, means anchoring in the damping means.
  • the invention relates to an installation embarkation and disembarkation of detachable chairlifts or gondolas, comprising at least one bearing system as described above.
  • the rolling system 1 is typically intended for a embarkation or disembarkation station for chairlifts and gondolas or disengageable analogs.
  • the vehicle follows the running rail 3 by a running roller 4 of a disengageable pliers not shown.
  • the rail 3 is mounted on a support structure 5.
  • the supporting structure 5 has a fixed part 6 comprising a zone receptacle 7 for the running rail 3.
  • Rail 3 follows a direction D in the station comprising rectilinear portions and typically horizontal curved portions.
  • the rail 3 is intended to be mounted on the fixed part 6, at the level of the zone receptacle 7.
  • a space 8 is located between the rail 3 and the receptacle area 7.
  • Support and damping means 9, designated indifferently means in the text, are located in space 8.
  • the rail 3 comprises a horizontal wall 10 and two side walls 11, 12 substantially vertical. Rail 3 is typically made of steel. Rail 3 has a width l and depth h.
  • the receptacle zone 7 comprises a horizontal face 13 facing the wall 10, a side face 14 facing the side wall 11, and a side face 15 opposite the side wall 12.
  • the horizontal face 13 has a width L, the sides 14 and 15 have a height H.
  • the distance L is greater than the distance I in order to accommodate the rail 3 in the receptacle 7.
  • I 65mm
  • L 110mm
  • h 36mm
  • H 50mm.
  • the receptacle zone 7 typically extends continuously over the entire length of rail 3 and below. According to a variant, this zone 7 is discontinuous but of sufficient width and strength to support the rail.
  • the upper ends 16, 17 of the side walls 11, 12 are located substantially in the plane, or close to the plane comprising the ends 18, 19 of the side faces 14, 15.
  • the roller 4 is in contact with the side wall 10, and bordered by the lateral faces 14, 15 of the rail 3.
  • the space 8 is filled by the damping means 9 which are provided under the shape of an elastomer or similar material matrix 20.
  • the space 8 is filled substantially at the ends 18, 19.
  • the elastomer 20 ensures the horizontal and vertical positioning and maintenance of the rail 3.
  • the mounting of the rail 3 on the fixed part 6 of the supporting structure 5 is done from the as follows: we place, by pouring it, the damping product in this case elastomer 20, which will both support and hold in place so secure the rail 3.
  • this rail is positioned 3 compared to a general geometrical need which is then freed from construction imperfections of the fixed part 6.
  • damping means 9 While the load is rolling, noise and vibrations are transmitted to damping means 9 and not directly to the receptacle 7, which are suitable absorb the mechanical stresses applied to rail 3 in the directions horizontal and vertical.
  • absorb we mean, depending on the material used, absorb by accumulating energy without dissipating it, or by dissipating it.
  • a another rail 3 of different dimensions for example of smaller width.
  • the structure of the rail 3 and of the receptacle zone 7 described can be adjusted if necessary if necessary.
  • the walls 11, 12 of the rail 3 are not parallel.
  • the receptacle zone 7 can moreover be made in one piece with, or fixed to, the fixed part 6.
  • the supporting structure 5 comprises a receptacle 7 ( Figure 2).
  • the receptacle zone 7 has a central face 21, a lateral face 22 and a lateral face 23. Face 22 ends in a fold 24, face 23 ends in a downturn 25.
  • the rail 3 comprises a central wall 26 facing the face 21, a wall side 27 facing face 22, and a side wall 28 facing face 23.
  • the damping means 9 are in the form of an extruded seal 9a for mounting and hanging the rail 3.
  • this rail may for example have two wings 29, 30 for anchoring in the extruded joint.
  • the two wings include multiple non-aligned segments.
  • the rolling system 1 may further comprise for a rail length defined, two keys 31a, 31b on either side of the rail 3, in the form of profiles, extending longitudinally between the folds 24, 25 and the walls 27, 28. These keys are in extruded joint.
  • the means damping 9 can be arranged continuously along the rail 3, or in several successive spaced zones. The choice is made in particular depending on the type of station used, the size of the devices, the noise reduction and desired vibration, cost and difficulty of mounting.
  • the elastomer 20 includes stiffening elements in metal or an alloy extending continuously or discontinuously in the elastomer.
  • the supporting structure 5 does not include a receptacle 7 (FIG. 3).
  • the fixed part 6 and the running rail 3 are connected by means damping 9 in the form of intermediate parts 32 incorporating vibration and noise absorbing elements.
  • the coins intermediate 32 are studs spaced along the rail 3 every 10 cm approximately or forming a continuous or discontinuous strip along the rail 3.
  • the elastic pads 32 are standard pads fixed on the part fixed 6 and able to receive different rails 3.
  • the pads 32 are connected to rail 3 using fixing screws 33, 34.
  • the screws 33, 34 are fixed on two wings 35, 36 horizontal and straight extending the face 37 of the rail 3.
  • the rail 3 and the intermediate parts 32 can be combined by gluing, tightening, screwing or the like, depending on the mechanical strength required for support rail 3.
  • the studs are capable of withstanding the forces in the vertical and horizontal due to the rolling of the load.
  • the structure of the rail 3 and depreciation means 9 can be very variable depending on the needs related to noise and vibration, and the ease of changing the rail 3 for the same part fixed 6 of a supporting structure 5.
