Definitions

  • the invention relates to a drive system for an arched escalator with a frame arranged helically in the vertical direction, which includes a transport section for sector-shaped treads in cross-section, an upper and lower turning section having chain wheels in connection with at least one drive and return tracks for the steps, which are in their hinged lateral edge areas, driven by a plurality of mutually parallel chains formed from inner and outer link plates, and each step in the respective edge area has an axle section equipped with a roller and a trailing roller spaced therefrom, which roll on associated guideways, at least one of which the respective end regions of the individual tabs and / or the associated axle section is provided with a bushing containing a spherical bearing.
  • a roller chain is provided on both sides of the steps, each step having a step axis connecting the roller chains.
  • the connecting links of the chain formed from link plates are connected via the free end sections of each step axis to the step axes or to one another adjacent to the step axis only by two spherical joints.
  • the cylindrical outer surface of the spherical joint which connects the connecting links to one another has essentially the same size as the rollers of the step chain, such that the cylindrical outer surface can interact with the chain wheel like a roller of the step chain.
  • the drive chains for curved escalators are guided on a helically arranged path, the rollers rolling on corresponding guideways.
  • the drive chains run at different circumferential speeds, so that when the path radii change, especially in the transition and deflection areas, deformation problems arise from the slope into the landing area that cannot be completely overcome by the proposed construction.
  • a curved escalator can be found in DE-C 34 32 961, which contains a multiplicity of steps provided with step axes which are separated by step chains are interconnected.
  • Carrier rollers are rotatably mounted on the step axes, and in addition guide rollers running on guide rails are provided which rotate about an axis perpendicular to the step axes.
  • the guide rollers are only provided on the outer end of the stepped axes.
  • the step chains can be deflected three-dimensionally by means of a first connecting element which is connected to the step axis and by means of a second connecting element which adjoins the first connecting element.
  • a first connecting element which is connected to the step axis
  • a second connecting element which adjoins the first connecting element.
  • the object of the invention is to overcome the disadvantages of the St.d.T. to overcome and further develop the drive system so that a transition as free of constraint as possible, in particular in the transition and deflection areas of the curved escalator, can be realized.
  • both end regions of the individual inner plates are provided with bushings containing spherical bearings, and in that the respective roller also having a spherical bearing is mounted on the one hand between parallel inner plates in the area of the associated axle section and on the other hand between the spherical bearing bushes of the respective end regions of the inner plates are each arranged.
  • each roller is provided on the one hand between the inner straps and on the other hand is equipped with a spherical bearing, in addition to a reduction in the installation space, a much improved mobility of the entire components relative to one another is brought about, so that in particular in the transition and deflection areas of the curved escalator the unwanted constraints and deformations can be optimally compensated for without increasing friction and / or deformation or damage to the corresponding components.
  • the respective axle section preferably projects through the roller and ends in the wall area of the inner link facing the frame outer areas without passing through its end face, where it is then fixed, for example, by a snap ring if necessary flush with the end face of this inner link.
  • a supporting element for receiving upper and lower guide rollers can be provided in the region of this inner link plate without influencing the mobility of the respective axle section.
  • the support element can be a separate body, which is detachably connected to the associated tab, or can be formed by approaches which are used when the tabs are produced, e.g. by stamping, molded directly onto it and bent in a further operation.
  • a drive system in which the respective turning section of the curved escalator is formed by two spaced-apart chain wheels, each of which can be connected to one another by a shaft which are provided on the outer circumference for deflecting the chains with a large number of rounded recesses receiving the bushings, depending on the chain pitch for receiving and guiding the roller arranged between the bushings in the region of the respective sprocket, a further recess whose pitch circle diameter is less than that of the sockets.
  • Such a drive system further includes a drive in the area of at least one of the turning sections, the drive shaft of which receives the sprockets, one of the sprockets, in particular the one with the smaller diameter, being adjustable in the circumferential direction relative to the other sprocket.
  • This can be done, for example, through elongated holes into which bolts of the drive shaft protrude.
  • the angular offset of one sprocket relative to the other is dependent on the diameter of the sprockets and the different speeds of the inner and outer chain.
  • the sprockets of the non-driven turning section are freely rotatable on their shaft. Depending on the diameter differences, it can happen that the outer chain runs approx.
  • driver elements are provided in the area of the chain wheels which serve to receive and guide the drag rollers provided in the area of the treads. This measure causes the respective steps to be guided in the deflection area, which increases safety when the steps are inclined.
  • the driver elements can be individual elements which, after the envelopes have been determined, are produced in the course of the rotation of the trailing roller axis and are provided in the region of the chain wheels.
  • the driver elements for example as grooves, in separate disks to bring, which are then placed on the shafts and connected to the sprockets.
  • FIG. 1 shows a schematic sketch of an arched escalator 1, which essentially contains the following components: a vertically helical base 2, which forms the frame for the curved escalator 1 and receives the essential drive elements, frame outer sides 2a, 2b, an analogous helical balustrade 3 including handrails 4 and steps 5, which in the area of the helix a transport section 6 , form an upper and a lower turning section 7, 8 and return tracks 9 for the drive chains 10 only indicated here.
  • a vertically helical base 2 which forms the frame for the curved escalator 1 and receives the essential drive elements
  • frame outer sides 2a, 2b an analogous helical balustrade 3 including handrails 4 and steps 5, which in the area of the helix a transport section 6 , form an upper and a lower turning section 7, 8 and return tracks 9 for the drive chains 10 only indicated here.
  • FIG 2 shows a perspective partial view of a drive chain 10, which consists of a plurality of interconnected inner plates 11 and outer plates 12, which are connected to one another in their end regions via bolts 13 are connected.
  • the bolts 13 are surrounded by a bush 14 in the area of the inner plates 11, a spherical bearing 15 extending between the bolts 13 and bush 14.
  • a roller 17 extends on the step side, which is arranged between the spaced inner plates 11, the axle section 16 projecting through the inner plate 11 and the roller 17 on the one hand and ending in the wall section 18 of the inner plate 11 on the other hand, where it is fixed, for example, by a snap ring, not shown here.
  • Each roller 17 includes a spherical bearing 19, similar to the bolts 13, so that this drive chain 10 is optimally movable.
  • a support element 21 is provided, which is detachably connected to the associated inner plate 11.
  • the support element 21 serves to receive upper and lower guide rollers 22, 23, which are provided for reducing external forces and roll on guide profiles (not shown here).
  • FIGS. 3 and 4 show a partial area of the drive chain 10 according to FIG. 2 on the one hand as a side view and on the other hand as a top view.
  • the inner plates 11 and the outer plates 12, the bolts 13 and the bushings 14 surrounding them, including spherical bearings 15, the roller 17 can be seen , the axle section 16, which extends into the area of an only indicated step 5 including the drag roller 5 ', the support element 21 and the guide rollers 22, 23, which are fastened in the support element 21 by means of a pin 24.
  • the end face 25 of the axle section 16 ends in the wall area 18 of the respective inner link 11 without passing through the end face 20 there and is fixed there in this area by means of a snap ring 35.
  • FIG. 5 shows, as a further component of the drive system according to the invention, a sprocket 26 provided in the respective turning section.
  • the run-up area, the link chain 10 not shown here is indicated by dash-dotted lines.
  • the diameter of the bushings 14 is on the circumference 27 of the chain wheel 26 adapted recesses 28, 29 are arranged, the dashed area 30 representing the pitch circle of the bush axis 36.
  • a deeper recess 31 is provided between the recesses 28, 29 and serves to receive the roller 17, the pitch circle 32 of which has a smaller radius than that 30 of the bush axis 36.
  • FIG. 6 shows a schematic diagram of a turning section 7 which contains two chain wheels 26, 26 'with different diameters, which are connected to one another by a shaft 37.
  • the recesses 31 for receiving the rollers 17, which are held between the inner plates 11, can be seen. Due to the differences in diameter of the outer and inner sprockets 26, 26 ', the smaller inner sprocket 26' runs 10-15% faster than the outer 26 depending on the diameter difference. Accordingly, the distance a 'of the shaft 37 is also greater than the distance a es for sprockets of the same size would. Since the chains 10 should not run obliquely but straight on the associated chain wheel 26, 26 ', these parameters must also be taken into account, which is illustrated in FIG. 7.
  • FIG. 7 shows the arrangement of an outer and an inner sprocket 26, 26 '.
  • the drive axle 38 which is only indicated here, is provided in the region of the smaller sprocket 26 'with bolts 33 which are guided in elongated holes 34 of the smaller sprocket 26', so that an optimum before the arc escalator is put into operation Adjustment of the two sprockets 26, 26 'to one another can be brought about, and the chains (not shown) can run evenly and in a straight line onto the sprockets 26, 26'.
  • the respective angle of rotation alpha is dependent on the difference in diameter of the chain wheels 26, 26 'and the difference in length of the distances a, a' according to FIG. 6.
  • FIG. 8 shows a drive plate 39 for the towing rollers of the treads 5, which are not shown here, which can be placed, for example, on the drive axle 38 and connected to the associated chain wheel 26, 26 '(not shown).
  • driving elements 40 introduced in the form of grooves which correspond to the rolling geometry of the towing rollers when the treads 5 rotate around the chain wheels 26, 26 'in the region of the respective turning section.
