Definitions

  • the invention relates to an inclined elevator consisting of a plurality of telescopic sections, the individual telescopic sections, which can be telescoped by means of at least one rail cable, have guide rails for a load platform or the like that can be moved thereon, wherein a pivoting device is provided for pivoting a partial length of the inclined elevator relative to a further partial length.
  • European patent application 00 80 038 discloses an inclined elevator of the aforementioned type, in which the upper "partial length” can be moved as a telescopic part into the underlying "partial length” of the inclined elevator.
  • the upper part length is partially extended so that corresponding swivel joints are made to coincide.
  • the kink can then be made using the rail cable.
  • Inclined lifts of the aforementioned type have proven themselves. In particular, they enable the last (upper) telescopic section to be bent by the operator located on the floor by means of a hydraulic thrust piston transmission or with the aid of the rope which also extends the individual telescopic sections to one another, i.e. no second cable winch is required, for which purpose appropriate pulley-type cable guides have to be accepted.
  • a disadvantage of the known solution was that the two joints of the last telescopic section and the second last telescopic section have to be moved over one another almost exactly in order to be able to bend them. Since the second to last telescopic section also has an articulated joint, there are at least four parts which are guided into one another and which have to be matched to one another in a relatively precise fit in order to keep the friction as low as possible. With corresponding wear due to high stress caused by the load platform moving over the kink area, the guide parts may be deformed, which in turn leads to increased friction and malfunctions when driving through the load platform.
  • the invention has set itself the task of finding a solution in which the aforementioned disadvantages are avoided while maintaining the advantages of the known solution.
  • the task is therefore to reduce the number of immediately bendable kink area of the guide rails lying in the reduction of the merged
  • the aim is to achieve a displacement of the swivel device that is as space-efficient as possible and a more advantageous design of the swivel joints. with a compact design, a favorable introduction of force into the parts to be pivoted against one another is to be achieved.
  • the invention thus frees itself from the idea that - as is usual with inclined lifts - the last telescopic section must be insertable into the penultimate one and must have a joint at its lower end for the purpose of kinking. Rather, the measure that the articulated joint itself does not belong to the telescopic area, i.e. cannot enter an adjacent telescopic section, can be used with the help of the hydraulic thrust piston transmission to form the swiveling guide rail which forms the upper part length or at least forms part of this upper part length with a corresponding arrangement of the hydraulic thrust piston transmission are pivoted so far that they can be brought into a stowage position running parallel to the adjacent lower guide rail.
  • Claims 2-12 relate to the arrangement and design of the swivel joint (and the swivel paths resulting therefrom), which is arranged with the direct connection of the two adjacent guide rails in the region of the guide rail raceway, so that the load platform or the like can drive over the swivel joint without problems, without a gap opening in the pivot point during the bending process.
  • claims 14-21 contain advantageous configurations of the bearing of the thrust piston transmission.
  • the features listed here result in a bending-free mounting, in particular of the piston rod (link guide), and at the same time an advantageous spatial arrangement has been found between the adjacent rails of the telescopic boom.
  • the design of the link directly or indirectly adjoining the piston rod of the hydraulic thrust piston transmission has resulted in a compact design which can be arranged in a space-saving manner in the area of the wheel support, but which nevertheless has a pivoting angle of over 180 ° can be achieved.
  • the special design of the handlebars allows a relatively short stroke of the thrust piston transmission.
  • the fork-shaped design simultaneously stabilizes the telescopic section to be swiveled transversely to its longitudinal axis. Details of this are characterized in claims 23-25.
  • Claim 26 clarifies that the telescopic shots which can be swiveled against one another are practically shots of "normal length", i.e. there is no kinking within a telescopic shot, but the swivel joint connects the upper end of a telescopic shot with the lower end of a subsequent shot.
  • the inclined elevator 1 can be seen, which is formed from the telescopic sections a - f.
  • the telescopic sections a - d are telescopic by means of a rope, not shown. Each individual telescopic section forms the guide rail for a load platform 3 or similar truck that can be moved on it.
  • the total number of telescopic shots a - d was designated with partial length 1; the total number of telescopic sections e and f with partial length 1 '.
  • the telescopic section f is preferably telescoped by hand with respect to the telescopic section e.
  • a swivel joint is arranged at 6; the swivel device itself was assigned position number 2.
  • the guide rail 7 ' can be angled relative to the guide rail 7 - for example against the roof of a house 5.
  • the entire inclined elevator can be moved by means of a chassis 4.
  • FIGS. 2-4 Details of the swivel device can be seen from FIGS. 2-4.
  • the swivel joint 6 is arranged in the region of the guide rail track 11 at the free ends 9 and 9 'of the guide rails 7 and 7'.
  • the guide rail track 11 is formed by the mutually facing flanges 12 of the guide rails 7 and 7 '.
  • a link guide 18 is arranged, which consists of two U-profiles 19 facing each other with the flanges.
  • the hydraulic thrust piston gear 8, the cylinder 13 of which is located within this link guide 18 supports its lower end on a cross member 14 which connects the two guide rails 7 to one another.
  • the piston rod 16 assigned to this cylinder carries at its free end 15 a slide bearing 17 which is designed as a roller bearing and which is positively guided in the link guide 18.
  • the upper end of this link guide 18 is (see FIG. 3) additionally supported by support struts 20 in order to prevent bending.
  • the support struts 20 are connected at their other end to a cross member 32 which connects the two support struts 31 of the wheel support 10 to one another.
  • the free end 15 of the piston rod 16 rotatably connects to a link 22, which acts with its free end 23 on an arm 24 of a stiff, three-armed link 25.
  • This rigid three-arm link 25 is connected with a further second arm 26 via a swivel joint 34 to the cross member 32 arranged on the wheel support 10 and with its third arm 27 via a further swivel joint 35 to a swivel lever 28 which (see FIG. 4) is fork-shaped.
  • the connecting joints 30 of this fork are articulated via a further swivel joint 36 to the lower mutually facing flanges 12 'of the guide rails 7'.
  • FIGS. 3 and 5-7 The individual pivot positions can be seen from FIGS. 3 and 5-7, FIG. 5 showing the stowed position when pivoted completely, FIG. 6 showing an intermediate position in a semi-erect position, and FIG. 3 the stretched bottom sition and Fig. 7 shows the actual position of use when resting against the roof.
  • the special design of the swivel joint in connection with the swivel device ensures that the joint point (swivel joint 6) is passed over correctly, the bevel 37 being chosen so that a sufficient swivel angle against the roof is made possible.
  • profile cross sections of the same size can be used beyond the pivoting area without losing effective usable length.
  • the hydraulic thrust piston gear is free of bending stresses and is stored in a space-saving manner within the last telescopic guide rail.
  • the hydraulic pivoting device shown in FIGS. 8-10 is generally designated 38. It essentially consists of the support strut 43, which is angularly rigidly connected to the hydraulically actuated, non-pivotable guide rail 39 and a hydraulic thrust piston gear 42 which is articulated on this support strut and which in turn acts on two links 44 and 45, the link 45 on the pivotable guide rail 40 and the link 44 is articulated on the non-pivoting guide rail 39. It can be seen that when the thrust piston gear 42 is actuated, the pivotable guide rail 40 pivots about the pivot joint 41 as shown in FIGS. 9 and 10 until the position shown in FIG. 10 is reached, which corresponds to the transport position.
  • Part length 1 in the illustrated embodiment has three mutually telescopic guide rails, of which the guide rail provided with the smallest cross section forms the last inner telescopic section g of this part length 1.
  • This telescopic section g is adjoined by the first outer telescopic section of partial length 1 ′, designated h.
  • This has a larger cross-section than the telescopic section g, so that the cross-sectional dimensions of the telescopic section, which is indicated as indicated, does not have to be reduced inadmissibly.
  • the telescopic sections g and h are connected by the hydraulic swivel device 38 shown in more detail in FIGS. 8-10.
  • the hydraulic swivel device 38 can be supported in the area of the eaves.
  • the load rope can be carried out to the extreme end 46 of the boom, so that the load platform can be moved over all part lengths 1, 1 'and 1 ". This is possible by combining the hydraulic swivel device 38 with the cable-operated swivel device 47.
