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, with the roller spacing on the slide during the transition from a telescopic section is arranged on the next changing adjusting device.
  • 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 known embodiment is not a forced adaptation to the changed diameter, but an elastic adjustment device. Otherwise, only the inner side rollers are adjusted elastically, but not the upper or lower rollers (US Pat. No. 3,891,062).
  • a further inclined elevator intended for the transport of material is known, in which the carriage has rockers which carry the upper and lower rollers (DE-OS 3 222 508).
  • the bearing of the rollers on the swingarms should make it easier to drive over kink points; on the other hand, the load transfer is evened out when the rail joints are passed over.
  • 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.
  • 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 resulting requirements for the slide guide can be mastered with the technical teaching according to DE-OS 32 22 508 as long as the profile in the area of the upper and lower rollers as well as side rollers (outer or inner rollers) is not particularly profiled experiences, which significantly increases the transition from one profile to another.
  • the object of the invention is therefore to improve an inclined elevator of the type mentioned in such a way that with relatively large changes in the distance 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 definable contact pressure, regardless of the extension length of the individual telescopic sections, so that the load suspension device is guided exactly on the guide rails and - if the load cable breaks, the resulting from the hour . d. T. (DE-OS 32 22 508) known eccentric brake can grip safely.
  • the invention solves the problem by the features of claim 1.
  • a device is provided on the guide rails in the transition area from one guide rail to the next one on the guide rails on the one hand and on the slide on the other hand, such that when the slide passes the transition point, these two devices are forcibly engaged with one another, so that as a result of this, there is a transmission Coupling of the roller distance between the upper roller and the lower roller is gradually reduced when the carriage moves up and is gradually increased when the carriage moves down, so that the roller distance is automatically adapted to the reduced "thickness" or the reduced “diameter” of the next smaller profile or vice versa .
  • This forced adjustment device can be different; it can be realized, for example, by a drive shaft arranged at the upper end of a telescopic section, which comes into positive engagement with a pinion arranged on the slide when it is passed over, the pinion adjusting the roller spacing via a device connected to it in a gearbox; however, it can also be realized by sliding corresponding wedge surfaces onto one another with the consequence of the forced adjustment of the roller spacing or the like.
  • the essential feature of the invention is that coupling elements are provided on the slide on the one hand and on the guide rails on the other hand, which inevitably come into engagement with each other when passed over by the carriage, with the result that, in accordance with this coupling, an inevitable change in the distance between the upper and lower rollers takes place , which is self-locking and only by renewed active coupling in the above Way can be reset.
  • the adjustment can be made by servomotors, hydraulic cylinders or the like.
  • the drive sticks addressed in claims 8-11 can be designed as toothed rack sections or preferably so that they are two side cheeks and pin connecting pins, in which a corresponding pinwheel wheel with appropriate teeth can engage between the free spaces of the pins.
  • pinion gear pinion
  • the spindle nut transmits its movement to the articulated arms of a parallelogram joint, the bearing blocks for the lower roller and the side roller being arranged at the free ends of the articulated arms.
  • the bearing blocks for the lower roller and the side roller being arranged at the free ends of the articulated arms.
  • it is proposed to force-adjust only one of these two roller sets (in each case underneath and. Outside of the guide rails running parallel to one another) and to couple the second roller set to the force-adjusted roller set in such a way that the forced adjustment is transferred to it.
  • an adjustment device should be provided in the second roller set, which allows the adjustment path of the second roller set to be adapted to the first positively adjusted roller set during assembly (claim 14).
  • these headstock sections Since for the forced adjustment when using the proposed headstock sections, these must have a certain length and since these headstock sections are preferably arranged on the crossbars connecting the two adjacent guide rails of a telescopic section at the upper end of the guide rails, it is proposed to laterally offset the headstock sections of adjacent telescopic sections so that the Telescopic shots can be fully retracted in the transport position.
  • a perfect and reliable adjustment is thus possible by means of the arrangement of two pinwheel wheels in a side-by-side arrangement, the one pinwheel wheel coming into engagement for example with the first telescopic shot and the second pinwheel wheel with the following telescopic shot.
  • the crossbars connecting the two adjacent guide rails of a telescopic section are alternately designed differently in the rail sequence, with rectangular sections having closed cross sections 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 expulsion means or forced insertion means can be performed, wherein as a forced expulsion means bolt chains according to the secondary 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.
  • a positive adjustment device 14 which forms the driving element 19 on the rail and is shown in the exemplary embodiment shown as a rack section 20 (see FIGS. 5-10).
  • the rack sections 20 are laterally offset, so that they can engage with the driving element 18 on the slide 9, the driving element 18 being designed as a pinion 21.
  • the pinion 21 is rotated and the roller position on the slide, generally designated 16, is activated.
  • the slide In its basic structure (see FIG. 5), the slide itself consists of two longitudinal beams 40, to which the spindle bearing 43 is connected, and two U-shaped cross beams 41, which have a bow leg 42 pointing downward.
  • the side member 40 also serves to connect the connection bracket 44 for the load rope and the eccentric brake 45.
  • the rotational movement of the spindle 22 is transmitted via the opposite thread 23 to the spindle nut 24, which in turn adjusts both articulated arms 26 of the parallelogram joint via an adjusting arm 34 via the short arm 46 of the upper articulated arm 26.
  • the upper articulated arm 26 is connected to a socket 47 which is fixed on a shaft 49 by means of a wedge 48.
  • the rotational movement of the shaft 49 is inevitably transmitted to the second bushing 47 ', which is fixed on the shaft 49 in the same way.
  • 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 pivoted at one end in the region of the stirrup leg 42 on an axis 50 and at the other end on the roller block 51.
  • 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.
  • the bushing 47 ' can be formed as a short bushing portion 53 compared to FIG. 4A, which is non-rotatable with the shaft 49 is connected.
  • an adjusting device 28 for example formed from a spindle or a screw, can be arranged, with the aid of which the bushing sections 53 and 53' can be rotated relative to one another, so that readjustment of the lower roller 11 and the side roller 12 of the second roller set compared to the first roller set is possible. From Fig.
  • 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.
