Definitions

  • the invention relates to an inclined elevator, in particular material or passenger elevator with a plurality of telescopic sections, which form guide rails for a carriage which can be moved there and which carries a load-carrying means and which is guided on the rail profile by means of upper rollers and lower rollers.
  • Such an inclined elevator is known in which, in addition to the usually outer lateral guide rollers, inner lateral guide rollers are arranged, which are elastically adjustable relative to the outer lateral guide rollers. This enables adaptation to different diameters (widths) of the guide rails.
  • the roll assembly after the aforementioned hour d. T. is preferably suitable for inclined lifts for the exclusive material transport, as they have become known from DE-OS 35 41 836.
  • Such inclined elevators consist of telescopic sections, which are formed from ladder-like connected rail profiles.
  • the known rail profiles are approximately U-shaped, ie "open" profiles, which are connected in the region of their mutually facing lower double legs by cross belts.
  • the upper and lower rollers run above and below the upper flange of these open profiles, so that in the transition from one telescopic section to the following telescopic section, a flange thickness must be passed by the slide.
  • the object of the invention is therefore to improve an inclined lift of the type mentioned in such a way that with relatively large changes in the distance of the profile height of the rail guide during the transition from a telescopic shot to the next one there is a safe and reliable slide guide. It should be ensured that the upper and lower rollers are always in contact with the guide rails with a determinable play or with a determinable contact pressure, regardless of the extension length of the individual telescopic sections, so that the load-carrying means are guided exactly on the guide rails and - if the load cable breaks - which from the hour d. T. (DE-OS 32 33 508) known eccentric brake can grip safely.
  • the invention solves the problem by the features of claim 1.
  • a device is provided on the slide which automatically changes the distance of the rollers when the slide passes over the transition point, so that as a result of this automatic adjustment, the roller distance between the upper roller and lower roller is gradually reduced when the slide moves up and is gradually increased as the slide moves down , so that the roller spacing is automatically adapted to the reduced “thickness” or the reduced “diameter” of the next smaller profile or vice versa.
  • a device is provided exclusively on the carriage, which is suitable for imparting such pressure to the rollers that they automatically change in width and height according to the reduced or enlarged rail profile when changing from one rail to the other consequences.
  • the roller adjustment is a gas spring which is clamped between the carriage on the one hand and the lower roller or the lower roller and the side roller on the other.
  • Gas springs of this type with a preload of, for example, 190 Kp are suitable for applying the necessary pressure for the rollers and, because of their large adjustment range, reliably guide the slide on the rails, which change in cross-section.
  • the parallelogram joint enables simultaneous adjustment of both the lower roller and the side roller using only a single gas spring, whereby the adjustment of the swivel angle and articulated arms to the rail profile when moving from one rail profile to the other always means that the lower roller is in contact as well as the installation of the side roller.
  • two sets of rollers i.e. a total of four sets of rollers
  • each set of rollers consisting of an upper roller, a lower roller and a side roller, and at least the respective "upper” and “lower” roller sets can be set separately (claim 5).
  • this can be carried out by means of an adjustable mounting of the gas spring on the slide or on the roller set (claim 7), preferably a gas spring being assigned to each roller set (claim 8).
  • the crossbars connecting the two adjacent guide rails of a telescopic section are alternately designed differently in the rail sequence, rectangular sections having a closed cross-section being provided in the case of one telescopic section and two U-sections arranged at a distance from one another in the next telescopic section, such that the length of the longer side of the rectangle of the rectangular profile closed in cross section is smaller than the distance between the webs of the U-profiles of the subsequent larger profile.
  • the forced extension means or forced insertion means characterized in claims 10 and 11 can be performed, with pin chains according to the second-order hour d. T.
  • FIG. 1 shows the inclined elevator 7, which has telescopic rails 1-6, the rail 5 being telescopic relative to the rail 6 by means of a thrust piston transmission 37 consisting of cylinder 35 and piston rod 36, the piston rod 36 on the cross-beam 17 ( Fig. 10) of the rail 5 is connected.
  • the rails 1-6 are pivotally supported on a chassis 38 designed as a mobile single-axle trailer via a telescopic support 39.
  • the load-bearing means designated 8 rests on a carriage 9 which is moved by means of winches 40 over a load rope.
  • each rail formed from two parallel rail profiles 13 and 13 ' has at its upper end 15 an upper crossbar 17.
  • the basic structure of the slide itself (see FIG. 5) consists of two longitudinal beams 40 and two U-shaped cross beams 41 which have a bow leg 42 pointing downward.
  • the longitudinal member 40 also serves to connect the connection bracket 44 for the load rope and the eccentric brake 45.
  • gas springs 34 are connected to brackets 14 of the slide base frame, which are connected at the other ends to bushings 47 and 47 ', respectively. (Only one gas spring 34 is shown in FIG. 5, a gas spring is preferably assigned to each roller set formed from the upper roller 10, lower roller 11 and side roller 12.)
  • the gas spring 34 acts via the short arm 46 of the upper articulated arm 26 on the two articulated arms 26 of a parallelogram joint, so that the parallelogram joint can be adjusted by the gas spring 34.
  • the lower articulated arm 26 (two articulated arms 26 are provided next to each other in the direction of movement of the slide (arrow direction 27)) is articulated at one end in the area of the stirrup leg 42 on an axis 50 and at the other end on the roller block 53.
  • the lower free end of the articulated arm 26, which is offset in the direction of the arrow 27, is rotatably connected to the free end of the axis 50.
  • the lower ends of the stirrup legs 42 are connected to one another by a longitudinal member 52.
  • a return cable 33 which is guided from the upper end 15 of one rail over the lower end 31 of the following rail to the upper end 15 of the next rail and is fastened there.
