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 intended for the transport of material, is known, in which the carriage is arranged with rockers which carry the upper and lower rollers (DE-OS 32 22 508).
  • the bearing of the rollers on the swingarms should make it easier to drive over kink points; on the other hand, an equalization of the load transfer at Reached over the rail joints.
  • 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, that is to say "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 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 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 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, the device Coupling of the roller distance between the upper roller and lower roller is gradually reduced as the carriage moves up and is gradually increased as the carriage 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.
  • 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 geared manner; 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 one another when passed over by the slide, 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 can only be reset by renewed active coupling in the manner described above.
  • the adjustment can be made by servomotors, hydraulic cylinders or the like.
  • the top role has proven to be advantageous to be arranged on the carriage without changing the distance and only to force-adjust the lower roller and, if necessary, the side roller (outer roller) for safe lateral guidance, the above-mentioned forced adjustment preferably being used with closed hollow profiles due to the large change in distance for each rail transition from the bottom to the top profile.
  • 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 bolts connecting these pinion sections, in which a corresponding pinion gear with corresponding teeth can engage between the free spaces of the pins. It should be ensured that the rack wheel (pinion) engages exactly between the first two tooth flanks or in the first free space between two cross bolts and after leaving the free space between the last two tooth flanks of the rack section or after leaving the last free space between the two Bolt of a headstock section as a result of self-locking immediately stops its rotary movement so that no impermissibly high or too low contact pressures occur on the guide rails. Small fluctuations can be compensated for by a conditionally elastic design of the roller adjustment device on the slide.
  • a roller adjusting device arranged on the slide details of a roller adjusting device arranged on the slide are proposed, a spindle being used to forcibly rotate a spindle on which a spindle nut runs, which in turn uses a corresponding lever linkage to control the distance between the upper roller on the one hand and the lower role and side role on the other hand changed.
  • 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 on the underside 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 positive adjustment is transferred to it.
  • an adjustment device should be provided in the second roller set, which enables the adjustment path of the second roller set to be adapted to the first positively adjusted roller set during assembly (claim 14).
  • the crossbars connecting the two adjacent guide rails of a telescopic section are alternately different in the rail sequence, rectangular sections with closed cross-sections 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 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 crossbar 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 mutually parallel rail profiles 13 and 13 ⁇ has an upper crossbar 17 at its upper end 15.
  • 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). 1 and 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 carriage 9 with Converts a rack section 20 to the pinion 21 the pinion 21 is rotated and the roller position, generally designated 16, is activated on the slide.
  • 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 in the same way on the shaft 49.
  • 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 connected is.
  • 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 role set compared to the first role 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.
