Definitions

  • the invention relates to an inclined elevator consisting of a plurality of telescopic sections, the individual telescopic sections forming guide rails which are guided against one another for a load suspension means which can be moved thereon, the upper section of an outer guide rail being able to be bent by means of a device which can be operated from the ground, and the angle of inclination of the upper section relative to the outer guide rail can be ascertained and a further guide rail is guided in the bendable upper section of the outer guide rail, using an articulated support boom at one end at the upper end of the outer guide rail and the other end at the bendable upper section of the outer guide rail, the length and / or inclination thereof relative to the outer guide rail for the purpose of adjustment the angle of inclination is changeable.
  • a support strut is arranged below the bendable section, which serves to support a cantilever which carries at its free end a sliding shoe which forms the bendable section of the penultimate guide rail.
  • the aforementioned slide shoe comprises the last guide rail guided in the penultimate guide rail.
  • the known kinking device enables kinking by an angular amount of approximately 44 degrees; This kink angle is not sufficient if the non-kinkable guide rails of the inclined cable must be set up steeply - for example at an angle of about 80 degrees - on a house wall and if at the same time the load to be transported by means of a slide on the guide rails is placed on a roof with a relatively flat surface Inclination - for example 30 degrees - or must be spent on a flat roof.
  • the object of the invention is therefore to provide a ground-operated kinking device, with the aid of which the roofing with a relatively low roof pitch or the loading of flat roofs with a relatively steep inclined elevator is possible, while still reliably driving over the so-called sledge over the Kinks should be guaranteed.
  • the aim is to increase the previous articulation angle by about 44 degrees; this kink angle could not be increased due to the given cable routing for the inclined elevator according to DBP 31 20 048.
  • the invention solves this problem by the teaching of claim 1.
  • a second support boom practically two articulation angles are created, so that the hitherto possible articulation angle is doubled with appropriate training.
  • kink angles of almost 90 degrees can thus be achieved, so that even with an inclined elevator that is very steep for reasons of space, it can be bent down to a flat roof and the sled with its load can travel over the double-kinked outer guide rail to the flat roof.
  • Each of the two articulated joints of the outer guide rail can be designed as a single joint or as a multiple joint.
  • the outer guide rail can be the penultimate guide rail; for example, it can also represent the third to last guide rail if, for example, a further, manually extendable guide rail is slidably guided in the second last guide rail provided with corresponding joints.
  • the kinking is preferably carried out by means of a winch operated from the ground by pulling rope; however, it can also be carried out hydraulically by means of one or two hydraulic thrust piston gears which can be operated from the ground.
  • the bendable sections arranged at the upper end of the outrigger arms practically form an extension of the outer guide rail, so that two extensions of the upper end of the outer guide rail are formed by the assignment of two outrigger arms, both of which are supported directly or indirectly at the upper end of the outer guide rail which form bendable sections.
  • Each of these two bendable sections is suitable for supporting and guiding a bendable section of an inner guide rail, so that two defined bend angles can be determined.
  • a double Ab kinking the outer guide rail proposed; the double kink is basically sufficient because kink angles of about 90 degrees can be achieved; in principle, the solution according to the invention can also be used for more than two bends.
  • each of the bendable sections of the outer guide rail is supported directly or indirectly on the outer guide rail below the lower joint, wherein according to claim 4 the bendable sections of the outer guide rail consist of corresponding outer guide rail or forming guide sections.
  • the bendable sections thus comprise the inner guide rail in the form of sliding shoes in a manner known per se.
  • Claim 5 defines the position of the support boom and the bendable sections with respect to the associated joints.
  • the maximum bending angle of each joint is between 30 degrees and 45 degrees; maximum angles between 60 degrees and 90 degrees are possible.
  • each of the two joints can be designed as a multiple joint.
  • Claim 9 specifies a preferred embodiment, with both joints kinking at substantially the same angular amounts simultaneously with the beginning of the kinking during the kinking. This is due to the gear coupling of the two sliding shoes, which is also characterized in claim 8, i.e. the movement imposed on the first (lower) slide shoe is automatically transferred to the second slide shoe as a result of the rigid coupling between the first and the second slide shoe.
  • both sliding shoes are supported on a respective support strut by means of an associated handlebar, i.e. the outer (upper) slide shoe is supported via its handlebar on the support strut assigned to it, but is at the same time forcibly coupled via its support arm to the second (lower) slide shoe, which in turn is supported on the outer guide rail via a handlebar on the support strut assigned to it.
  • an associated handlebar i.e. the outer (upper) slide shoe is supported via its handlebar on the support strut assigned to it, but is at the same time forcibly coupled via its support arm to the second (lower) slide shoe, which in turn is supported on the outer guide rail via a handlebar on the support strut assigned to it.
  • outrigger in the claims 11-14 possible embodiments of the outrigger are characterized; they can be formed from tension or compression struts, from hydraulic thrust piston gears or from combinations between hydraulic thrust piston gears and lever linkages, whereby according to claim 15 (using tension and compression struts) the kinking takes place by means of a pulley-like pull rope, according to claim 16 both Support brackets are connected in a common connecting joint to the first bendable section, whereby the positive coupling is given.
  • Claim 17 is directed to a further embodiment, wherein there is no forced coupling of the two bendable sections designed as sliding shoes; in this case, the first section that can be bent bends over its maximum possible angular range; only then does the second section begin the bending process. The re-erection takes place in reverse order.
  • Claim 18 designates an embodiment of the associated cable guide which is advantageous with reference to the teaching of claim 17 and which is expedient for moving the sliding shoes. It is understood that when using thrust piston gears, the bendable sections need not be designed as sliding shoes, provided the thrust piston gears are connected to the outer guide rail in an articulated manner.
  • Claim 19 is directed to the assignment of the corresponding joints of the inner guide rail in such a way that the joints of the outer and inner guide rails are in the same plane and can be bent.
  • the upper end 13 of the guide rail 2 can be seen, in which the lower section of the guide rail 1 is guided and locked.
  • the locking takes place by means of locking elements 41 and 41, which can be seen from the rope plan according to FIG. 5, such locking mechanisms are basically known from the German patent specification 31 37 847.
  • a support strut 25 is arranged which carries a support wheel 30 in the region of its free end 29.
  • a first support arm 14 is supported on the support strut 25, which is articulated at the other end to the bent section 16 designed as a sliding shoe 20.
  • a further support bracket 15 is connected at the same time, which in turn is articulated with its other end in the connecting joint 44 to the bent section 17, which is also designed as a sliding shoe 21.
  • the bent sections 16 and 17 form practically foldable extensions of the upper end of the guide rail 2 - although the foldable section 16 is dimensioned larger than the dimensions of the guide rail 2. It can be seen that the movement imposed on the bent section 16 by the support bracket 14 is transmitted via the support bracket 15 to the bent section 17.
  • the support arm 14 is assigned a link 31 designed as an insertion and extension limiter; the support arm 15 is a link 32 which is supported in the region of the support wheel 30 on a support strut 28.
  • a lower joint 18 is connected, which connects the guide rail 2 to a guide rail section 24 which is encompassed by the bent section 16 designed as a sliding shoe 20.
  • an upper joint 19 is connected, which connects the guide rail section 24 to another guide rail section 27 in an articulated manner.
  • the inner guide rail 1 has corresponding corresponding joints 36 and 37 which lie in the same plane with the joints 18 and 19 in the bent position.
  • a support strut 25 is arranged at an angle-rigid manner, which supports a support wheel 30 at its free end.
  • two support arms 14 and 15 ' are connected in an articulated manner, of which the first support arm 14 supports the bendable section 16 - which is also designed as a slide shoe 22 - while the support arm 15' supports the bendable second section which is also designed as a slide shoe 23 17 supports.
  • the connecting joint 47 on the first bendable section 16 two links 31 and 31 are connected, which form entry and exit limiters.
  • a lower joint 18 is connected, which connects the guide rail 2 with a guide rail section 42.
  • an upper joint 19 is connected to the lower bent section 16, which connects the foldable section 16 to a further guide rail section 43.
  • the inner guide rail 1 has joints 36 and 37 corresponding to the joints 18 and 19. From Fig. 6 it can be seen that in the extended position, the joints 18 and 36 lie one above the other, while the joints 19 and 37 are strongly displaced against each other. From this and from the rope guide to be explained, the kink situation shown in Fig. 7 results, i.e. it is only after the first bendable section 16 has been completely bent that the second bendable section 17 begins the bending process.
  • Fig. 8 explains in connection with the rope plan according to Fig. 9 that the pull rope 33 'coming from the winch via a rope bottle 35 on the lower bendable section 16 back to a rope bottle 47 at the upper end of the guide rail 2 and further arranged side by side ten cable bottles 48 and 49 on the upper bendable section 17 and the lower bendable section 16 and back to the winch 40 is guided.
  • the result of this is that the lower bendable section 16 first performs a pivoting movement; only after the swivel angle has been exhausted is the relaxation of the rope or the tightening of the rope transferred to the upper bendable section 17. 5 and 9, only five guide rails were shown, while the schematic representation of the inclined elevator according to FIG. 1 shows six guide rails. For the rest, the representation of the joints in the guide rail 1 has been omitted in the cable plans, because this can be seen from FIGS. 4 and 8 with sufficient clarity.
