Definitions

  • the invention relates to an escalator with two deflection areas and with a circumferentially arranged between the deflecting stepped belt according to the preamble of claim 1 and a method according to the preamble of claim 9.
  • Such an escalator and such a method are made US764906A known.
  • the step band has pivotable steps whose pivotal movements are predetermined during the rotation by means of stepped rollers or chain rollers and drag rollers, which are arranged on both sides of the steps and roll on rails.
  • the step band has by its circumferential arrangement serving for the transport of people and goods flow and a return of the stages serving return.
  • the deflection areas also serve as access areas to the step band in the lead of the step belt.
  • the treads are held at least three successive stages on the same horizontal plane, before the treads of the individual steps in the transition areas to the sloping, or inclined section of the escalator move in the vertical direction relative to each other and thereby a staircase is formed.
  • the step rollers and tow rollers arranged on either side of each step are arranged at different levels with respect to the tread of the step. The arrangement on different levels has the advantage that in the oblique portion of the lead on both sides of the step band only one feed rail has to be arranged, on which both the step rolls and the tow rolls roll.
  • each stage side band a first guide rail for guiding the step rollers and a second guide rail for guiding the tow wheels are required.
  • the first guide rails and the second guide rails extend between the two deflection areas over the entire return area of the step belt. This configuration allows to minimize the height of the deflection, since the stages located in the return in which, the height influencing, most advantageous position can be pivoted.
  • the object of the present invention is to provide a reliable escalator with a low-cost designed return.
  • an escalator with two deflection regions and with a step belt arranged circumferentially between the deflection regions, which step belt has pivotable steps.
  • said step band has by circulating arrangement serving for transporting people and goods flow and a return of the stages serving return.
  • a common return rail for the tow rollers and the step rollers are present in the return on both sides of the step belt.
  • the common return rails are arranged in an inclined portion of the return and between the two deflection and common return rails is ever a transition region available. In these two
  • a rotating conveyor is arranged in each case in transition areas, wherein the rotating conveyor conveys the step rollers from the common return rail to a first guide rail arranged in the deflection region and the tow rollers from the common return rail to a second guide rail arranged in the deflection region in a first direction of rotation of the step belt.
  • the tow rollers and the step rollers are accordingly combined on the common return rail.
  • the merging or separation of stepped rollers and towed rollers in the transition region has the particular advantage that the deflection areas have a height that at least do not exceed the heights of existing sentenceeppen.
  • the step band usually has two link chains, which are connected to each other transversely to the direction of rotation by means of stepped axes.
  • the step rollers can be rotatably mounted on these step axes and the steps can be arranged pivotably. Due to this design, the two link chains are arranged on both sides of the step band and the stepped axes traverse the theoretical lane of the towing rollers in the transition areas. Theoretical lane because in this area an interruption or a gap between the second guide rail and the return rail must be present to ensure the passage of the stepped axes.
  • the link chains instead of the link chains, other traction means such as belts, timing belts, steel cables and the like can be used more.
  • rotating conveyor In order for the tow rollers to be able to access the second guide rail assigned to them, a rotating conveyor device is provided in the region of this interruption or gap, which conveys an approaching tow roller to the second guide rail. Furthermore, the rotating conveyor must be designed so that an approaching step axis and step roller can cross this area trouble-free.
  • rotating conveyor is not necessarily to be understood that the entire conveyor rotates. It may be the entire conveyor, but it may also be designed only rotatable parts of the conveyor.
  • the rotating conveyor of a transition region may preferably have two conveyor rotors.
  • one of these conveyor rotors is rotatably arranged in the region of the interruption, so that on both sides of the step belt conveyor rotors are present. It is also possible that only one conveyor rotor is provided, but this could strain the step band asymmetrically.
  • the step rollers and drag rollers cross these conveyor rotors alternately. Due to the design of the conveyor rotors, the step rollers and tow rollers traverse them on different lanes and are thereby separated onto the first guide rail or the second guide rail. In order to ensure a trouble-free function, the two conveyor rotors of a transition region are preferably mechanically interconnected, so that both have the same speed and direction of rotation.
  • the rotating conveyor may comprise at least one, between two pulleys circumferentially arranged, in the transition region at the stage attacking conveyor belt.
  • the pulleys are arranged so that the step in the transition area comes into contact with a belt rim of the conveyor belt.
  • the conveyor belt acts directly on the step body of the stage, so that it is pivoted under the action of the conveyor belt in the desired direction. Since the step body has a triangular cross-section along its width, it preferably rests with its stepped trailing edge on the conveyor belt, so that the tow roller is pressed in the transition region against a guide surface which connects the second guide rail with the common return rail and above the lanes of the tractor wheel and the Step roller is arranged. The drag roller thereby enters the lane of the second guide rail.
  • the step body Since the conveyor belt is arranged only in the transition region, the step body loses contact with the conveyor belt as soon as the tug roller has reached a functionally reliable position on the lane of the second guide rail.
  • the arranged in the region of the stepped axis step leading edge never comes into contact with the conveyor belt, so that is held by the tensile force of the articulated chain, the step roller on their lane, which runs between the common return rail and the first guide rail or is arranged.
  • the rotating conveyor may comprise at least one, in the transition region at the stage engaging conveyor wheel.
  • the feed wheel acts on the steps in substantially the same manner as the conveyor belt described above.
  • the step body of the step is pivoted, so that the feed roller is guided along the guide surface into the second guide rail.
  • the shape or the curve of the guide surface is preferably matched to the position and the diameter of the feed wheel, so that the stage when passing through the transition region are exposed to the lowest possible caused by the rotating conveyor mechanical loads.
  • All three embodiments described above may be purely passive rotary conveyors whose movable parts such as the conveyor rotors, the conveyor belt or the impeller are driven only by the direct contact with parts of the step belt.
  • the rotating conveyor or its conveyor rotors, conveyor belt or conveyor wheel can also be actively driven.
  • the rotating conveyor can be driven directly by the step belt.
  • the movement of the traction means are mechanically tapped and transmitted to the movable parts of the rotating conveyor.
  • a mechanical tap can be done for example by a sprocket when the traction means is a link chain.
  • the rotating conveyor can also be driven by a conveyor belt independent of the conveyor belt.
  • a conveyor drive may for example be an electric motor, hydraulic motor and the like.
  • a monitoring device with at least one sensor and / or switch in the escalator can be present, which monitors the correct separation of the step rollers and tow rollers in the transition area. For example, if a tow role instead of being directed into the first guide rail in the second guide rail, an error signal is generated by the monitoring device, which is forwarded to a control device of the escalator. The control device of the escalator brakes immediately in the presence of an error signal from the tapes.
  • the rotating conveyor may also cause noise that could unsettle the users of the escalator.
  • a noise compensation device with at least one sound pick-up sensor and with at least one loudspeaker may be present in the escalator.
  • the at least one noise pickup sensor and the at least one loudspeaker are preferably arranged in the region of the transition region and / or the deflection region.
  • the noise compensation device and other operating noise of the escalator such as running noise of the step band in the deflection or the noise of the drive motor can be compensated.
  • the escalator should have the broadest possible step band with the narrowest possible width, so that as little as possible sales area is lost.
  • the common return rail contributes significantly to a favorable construction width ratio, since the step rollers and the tow rollers roll on very close to each other, parallel lanes on the associated common return rail. The distance of the lanes is determined only by the design and arrangement of the traction means, since the tow roller must cooperateschwenken the traction means. If the traction means are fastened on both sides of the step belt at the outermost ends of the step axles, the step rollers and trailing rollers can also roll on overlapping lanes on the common return rails. Preferably, the two lanes of the towing rollers and the step rollers are arranged on a same plane of the return rail.
  • a possible A method for modernizing an existing escalator comprises the steps of first removing all existing mechanical components except for the supporting structure or framework of the existing escalator. Subsequently, the new mechanical components are installed, wherein the new mechanical components comprise a circumferentially arranged step band, which has pivotable steps whose pivotal movements are specified during the circulation by both sides of the stages arranged on rolling rails rolling rollers and tow rollers. Furthermore, the mechanical components arranged on both sides of the step band, each having a common return rail for the tow rollers and the step rollers of the step band.
