Definitions

  • the invention relates to a cable conveyor system according to the preamble of claim 1.
  • Such a cable conveyor system is already known from CH-PS 671552.
  • a traveling or transfer rail extends along the transfer path of the stations of the system, on which the transport devices uncoupled from the conveyor cable move until after the coupling process, support, guidance and drive thereof have again been taken over by the conveyor cable.
  • the object of the present invention is to create a cable conveyor system which, by means of simplified application of the contact pressure, allows the aforementioned disadvantages to be avoided both on the side of the transport devices and on that of the station installations.
  • the contact pressure required for the frictional connection is applied either completely or partially by the weight of the transport devices themselves.
  • the frictional relationships between these and the friction wheels are changed to a lesser extent even under winter weather conditions. In particular, no snow can settle on the friction surfaces and the tendency to form ice on them is therefore also reduced.
  • the function of the transfer rail in the area of the friction wheels could be restricted to the fulfillment of a guiding task in that it is arranged flexibly in the pressing direction.
  • the friction surface can be attached to an organ of the same, on which pressing rollers or wheels act from above, which are rotatably mounted above the friction wheels.
  • the transport devices have running rails running in the transport direction, which cooperate in the stations with the fixedly rotatably mounted guide members and have known clamps with two movable clamping jaws, the orientation of which allows the path axis of the transport devices in the coupling area, ie during of the coupling and uncoupling process to be straight and parallel to the vertical plane containing the hoisting rope.
  • each transport device is preferably arranged in a downwardly open, U-shaped running rail, the legs of the running rail interacting with guide flanks provided on the friction wheels.
  • the roadway defined by the friction wheels is at least at the transition lower than the running surface of the transfer rail and, on the other hand, the conveyor cable is above this web at the time of coupling or uncoupling.
  • FIG. 1 schematically denotes the conveyor cable entering the station.
  • a running section in the form of a deceleration section 4 is assigned to the entry of the rope 2 in the direction of entry indicated by the arrow 3, which is part of a circular route 1 which continues until the rope (not shown) leaves the station.
  • the deceleration section 4 has a set of alternately arranged wheels 6 and 8 of the same diameter, which are rotatably mounted in a fixed position.
  • Another set of wheels 10 also arranged in this way is found in a driving section in the form of an alighting section 12 adjoining the deceleration section 4. Both the wheels 6 and the wheels 10 are driven friction wheels, the diameter of the latter being the same like that of wheels 6, 8.
  • All of the friction wheels 10 provided in the disembarking section are driven at the same circumferential speed, which is lower than the circulating speed of the conveyor cable 2 and is in a fixed ratio to this.
  • the friction wheels 6 are driven in the inlet direction 3 by the same speed jumps decreasing speeds.
  • the circumferential speed of the friction wheel 6 ' coincides with the rotational speed of the conveyor cable 2, while the friction wheel 6' 'has a circumferential speed that is one speed jump higher than the first friction wheel 10'.
  • the arrangement of the friction wheels 6 and 10 corresponds to known deceleration or alighting sections.
  • the support wheels 8, whose function is discussed below, are freely rotatable.
  • the center distance between adjacent friction wheels 6 is slightly more than twice as large as the center distance 9 between adjacent friction wheels 10.
  • exit section here in the form of a transfer arch 14 adjoins the exit section 12 in a likewise known arrangement.
  • a chain 17 of a chain conveyor, generally designated 16 runs along the transfer arch 14.
  • the chain 18 having driver 18 loops around sprockets, one of which is indicated at 19.
  • a horizontally extending transfer rail 24 present in the transfer arch 14 ends above the two last friction wheels 10 ′′ of the exit section 12. Accordingly, in the area of the sections 4 and 12 there is in any case a rail serving as a carriageway and taking over support tasks not provided. Rather, in these sections 4 and 12, the wheels themselves form a roadway indicated by the broken line 20, which replaces such a rail.
  • a known decoupling rail 26 begins in the area above the first wheels 6, 8 of the deceleration section 4.
  • a support profile 28 on which the decoupling rail 26 and an angle profile designated 30 are attached.
  • the carrier profile 28 and the angle profile which together extend over the length of the sections 4 and 12, together form a U-shaped stabilizing rail 32.
  • a hold-down rail 34 is also flexibly attached to the carrier profile 28 via a spring leg 36, which in the direction of deflection via a rubber-elastic tubular profile 38 is braced against the carrier profile 28 and which can extend in section 4 and optionally also in section 12.
  • the friction wheels 6 are connected in a known manner to two pulleys 40 and 42 of different diameters, this connection being able to have a known, limited freewheel (not shown).
  • CH Patent 671552 in which such a freewheel as well as the drive connection between adjacent friction wheels 6 is explained by means of V-belts, not shown here.
  • the friction wheels 10 are non-rotatably connected to pulleys, all of which have the same diameter, and are also connected to one another and to the drive via V-belts.
  • the transfer rail 24 formed by a round bar is fastened to a C-profile 44 (FIG. 4) which, like the support profile 28, can be hung directly on the ceiling structure of the station.
  • FIG. 1 designates armchairs which are located within the transfer path 1, the design of which is explained below with reference to FIGS. 2, 3 and 4.
  • the clamp 52 can correspond to that which is known from the CH patent 661013 is known. In any case, it is important for the present exemplary embodiment that the clamp 52 has two movable jaws 54 and 56. Thus, when the clamp 52 is opened, both jaws 54, 56 can remove themselves from the conveyor cable 2 by the opening movement. This means that for separating the rope and clamp when uncoupling or for joining together when coupling the chair 50, the chair 50 can be held on a path that runs parallel to a vertical plane 5 containing the conveyor cable 2 (FIG. 3).
  • the clamping jaws 54, 56 are articulated to one another via a bolt 58 and, moreover, to a support shaft 62 in a manner not shown.
  • the clamping jaw 54 has an actuating arm 64 rigidly connected to it, on which, at a distance from one another, two actuating rollers 66 intended to cooperate with the stationary decoupling rail 26 are rotatably mounted.
  • the support axle 62 rotatably passes through a chassis body 70 and a self-aligning bearing 72 of an armchair suspension 74.
  • the end 68 of the support axle 62 facing away from the clamp 52 carries a rotatable guide roller 76 which interacts with the stabilizing rail 32 in order to prevent the armchair from swinging sideways.
  • a straight running rail 80 is rigidly fastened to the undercarriage body 70 below the support axis 62 and runs transversely to this and therefore parallel to the vertical plane 5 containing the conveyor cable 2.
  • the U-shaped running rail 80 which is open at the bottom, has legs 82, on the inner sides of which guide surfaces 84 are formed and, with this but firmly but interchangeably connected, contains a profile body 86, on which a downwardly directed cross section concave friction surface 83 is provided.
  • the profile body 86 is preferably made of an abrasion-resistant material, for example polyamide 6, which has a high coefficient of friction even when wet, by casting. In order to enable the replacement when worn, the profile body 86 could also be non-detachably connected to the running rail 80 and be interchangeable with it.
  • the running rail 80 interacts with one of the friction wheels 6 and 10, which, like the wheels 8, are equipped with a correspondingly profiled convex tire 46.
  • the wheels 6, 8 and 10 have guide flanks 48 on both sides of the tire, which are overlapped by the legs 82 of the running rail 80, so that the guide surfaces 84 cooperate with the guide flanks 48.
  • the length of the running rail 80 and the surfaces 84 and 83 is somewhat greater than the center distance 7 or twice the center distance 9, so that in sections 4 and 12 it always interacts with two wheels 6, 8 and 10. Accordingly, the armchair 50 is not only stably supported on the wheels in the direction of transport, but also its straight running is achieved by lateral guidance.
  • the undercarriage body 70 carries two rollers 90 which are spaced apart from one another in the transport direction and are rotatably mounted and have a concave profile 92.
  • the transfer rail 24 engages in the profile 92 of the rollers 90 and guides the armchairs 50 located on the transfer arch 14 when these are moved further by the chain conveyor 16.
  • An armchair 50 ' is shown in the delay section 4, an armchair 50' 'which has run in earlier in the alighting section 12 and finally an armchair 50' '' in the transfer sheet 14.
  • the armchair 50 ' is coupled to the conveyor cable 2, but the latter has already reached the carriageway 20 and is supported on the wheels 6 and 8 according to the invention.
  • the armchair 50 ′′ which also moves on the road 20, is supported exclusively on the wheels 10.
  • the armchair 50 '' ' is located on the transfer rail 24, which supports and guides it in a conventional manner.
  • an armchair 50 runs into the station in the direction of arrow 3 when the conveyor cable 2 rotates, it comes into contact with its running rail 80 with the wheels 8 and 6 ′ which form the start of the roadway 20.
  • the guide roller 76 has also run into the stabilization rail 32, which determines the transverse position of the armchair 50.
  • the rollers 90 engage with the hold-down rail 34, thus preventing the chassis body 70 from swinging longitudinally and thus also lifting the rail 80 from the wheels 6, 8 accordingly.
  • the actuating rollers 66 of the clamp 52 now reach the area of influence of the decoupling rail 26, which, when the armchair moves further in the direction of entry 3, causes the clamp 52 to be opened while the clamp jaws 54, 56 are moved transversely to the conveyor cable 2.
  • the chair is now guided by the friction wheels 10 and the guide flanks 48 provided on them.
  • the chair 50 ''' is taken over and conveyed on by the chain conveyor 16 in a known manner. It can be seen from FIG. 4 that in the open state of the clamp 52, it deviates downwards, so that the engagement of the C-profile carrying the transfer rail 24 under the rollers 90 has become possible.
  • the chain conveyor 16 transfers the armchair 50 '''at the end of the transfer sheet 14, not shown, to the friction wheels of an entry section, also not shown, which corresponds to the exit section 12.
  • the subsequent acceleration section not shown, corresponds in structure to the deceleration section, whereby - initiated by a Coupling rail - the clamp 52 at the outlet end of the same finally couples the armchair to the conveyor cable 2.
  • rollers above the supporting axis and therefore also above the clamp allows the transfer rail 24 to be supported directly or in any case without great effort by means of a suitable profile, since a suspension encompassing the clamp is superfluous.
  • circular route 1 could also be replaced by a continuous route in an intermediate station of a cable car system having several sections.
