Definitions

  • the invention relates to a device for driving the handrails and the steps or pallets of passenger conveyor systems together and in the same direction.
  • a drive unit for escalators which is arranged within the circumferential step belt and consists of an electric motor, gearbox and handrail drive, the drive shaft of the gearbox simultaneously serving as the main drive shaft of the step belt.
  • the rotor that forms the housing of the electric motor and is designed as a brake drum on its outer circumference is overhung on the input shaft of the transmission.
  • the torque of the transmission is supported by a torque support on the handrail drive shaft, which is arranged perpendicular to the input shaft and is driven by means of positive locking means.
  • the stator of the electric motor flanged to the gearbox serves as an end cover for the bearing of the input shaft.
  • the handrail drive now located directly behind the electric motor is driven by an intermediate gear from an intermediate shaft.
  • the handrail drive wheels carrying the handrail drive wheels are now driven by means of a positive connection between the main drive shaft and the handrail drive chain.
  • the disadvantage here is that the drive concept selected requires a relatively high level of construction to be able to drive the drive wheels and the handrail steering wheels together. Aids such as chains are used for this purpose.
  • Aids such as chains are used for this purpose.
  • the handrails advance or lag behind the step belt due to slippage, stretching of the chains or the like, which is suitable for people on the step or pallet belt stand and hold on to the handrail, can have problematic effects.
  • the installation space required to implement this drive concept is considered to be relatively large.
  • the object of the invention is to overcome the disadvantages of the Std.T. to overcome and to provide a drive concept that can be accommodated in a space that is limited in space and by means of which the leading and trailing of the handrail or handrails compared to the step or pallet belt is largely avoided.
  • This goal is achieved with a device for jointly and in the same direction driving the handrails and the steps or pallets of passenger conveyor systems, in particular escalators and moving walks, by means of at least one drive unit containing a drive shaft or several drive shaft areas, by the drive wheels designed as chain wheels for the steps or pallets are provided coaxially to the handrail deflecting wheels and in particular are detachably connected to them, the drive shaft or the drive shaft regions being guided in the region of at least the drive wheels for the steps or pallets.
  • the structure and arrangement of the drive are negligible for realizing the subject matter of the invention, since only the action of the forces of either a common drive shaft or a plurality of drive shaft areas is at least important for the drive wheels for the steps or pallets, which are then in the same way via the corresponding connecting elements affect the handrail idler wheels.
  • the handrail deflection wheels can be formed in one piece. However, these are preferably designed in segments, with either the one-piece handrail deflection wheels or the segments being provided with friction linings for taking the handrails with them.
  • the segment-like design in connection with the friction linings is to be regarded as more advantageous than a one-piece version that wear of the friction linings without having to loosen or remove the associated handrail, the segments can be replaced individually.
  • the development of the drive elements goes in the direction of low-maintenance or maintenance-free design.
  • chains that are not insignificant are still used today. If the drive wheels are provided coaxially with the handrail deflecting wheels, it can happen that due to the continuous or discontinuous lubrication of the chains, lubricants can also get into the area of the handrail deflecting wheels, so that contamination of the handrails or other peripheral components cannot be ruled out.
  • oil deflectors between the drive wheels and the handrail deflection wheels, so that an undesired penetration of lubricant into the area of the handrail deflection wheels is reliably avoided.
  • the oil deflectors are preferably made of sheet metal and can also be segment-like, analogous to the segments of the handrail deflection wheels. It is also conceivable that the oil deflectors are connected directly to the segments of the handrail deflection wheels.
  • the subject of the invention is thus distinguished from the Std.T. as a space-saving design, the undesired leading or lagging of the handrail or handrails compared to the step or pallet belt largely avoided, if not excluded, since both wheels in the same direction, i.e. run at the same peripheral speed.
  • FIGS. 1 and 2 different views of the drive area of an escalator, not shown.
  • Figures 1 and 2 show a schematic diagram of the drive area 1 of an escalator, not shown.
  • a drive unit not shown, can be seen 2
  • drive shaft areas 3, 4 drive wheels 5, 6 designed as sprockets, coaxial handrail deflection wheels 7, 8, drive chains 9, 10 for driving steps of the escalator (not shown), the steps being carried by the bolts mounted on the chains 9, 10 11.12 are connectable.
  • the drive unit 2 which usually consists of a motor-gear combination, is also provided in this example coaxially with the drive wheels 5, 6, although other drive concepts are also conceivable.
  • the handrail deflection wheels 7, 8 are formed, as can be seen in particular in FIG.
  • both the drive wheels 5, 6 and the segments 13 are provided with axial projections 20, 21 on the face side, in the region of which the screws 14 are provided.
  • the screws 14, starting from the drive wheels 5, 6, are guided in the direction of the handrail deflection wheels 7, 8.

Abstract

L'invention concerne un dispositif permettant d'entraîner en commun dans le même sens les mains courantes et les marches ou palettes d'installations de transport de personnes, à l'aide d'au moins une unité d'entraînement contenant un arbre primaire ou plusieurs zones d'arbres d'entraînement. Les pignons d'entraînement prévus pour les marches ou palettes se présentent sous forme de pignons à chaîne et sont disposés coaxialement aux roues de renvoi des mains courantes, roues auxquelles ils sont notamment reliés de manière amovible. L'arbre primaire ou les zones d'arbres d'entraînement est(sont guidé(es) dans la zone au moins des pignons d'entraînement prévus pour les marches ou palettes.
