Definitions

  • the invention relates to a drive system for escalators and moving walkways with at least one drive chain and spaced from each other Deflecting elements for the drive chain, wherein the drive chain via bolts connected to steps or pallets of the escalator or the moving walkway, the positioned between two joints of the drive chain and each with a Castor are provided.
  • escalators which are heavy duty escalators outdoors, for example in underground shafts or the like, are used.
  • link chains used as drive elements, with respect to the larger dimensioned drives the step rollers outside the drive chain are provided.
  • the design effort given here is essential larger than a so-called department store escalator, which at the same time Also, the total width of heavy duty escalators to provide greater than at a department store escalator.
  • DE-A 17 56 813 is a roller step-chain connection of Escalators to take, in which the stepped bolt between two Joints of the drive chain is provided.
  • the rollers between two joints of the drive chain inside or outside the Inner tabs or outer plates are provided.
  • US-A 6,016,902 shows the upper deflection of a Escalator.
  • the steps here are like a bicycle chain with a Variety of rollers provided outside the deflection on one unroll the corresponding guideway. Due to the multitude of Guide rollers must the sprocket in a similar manner with a high Number of dome be provided.
  • the aim of the subject invention is that in the generic part of the first drive described drive system for escalators and To further develop moving walkways such that a simplification of the Construction costs, in particular the heavy-duty escalators or wheel platforms, is given, so that possibly identical or similar parts for use can come without this being detrimental to the different Driving forces affects.
  • the respective drive chain - without the bias to reduce - before unloading into the sprocket taking one Another idea of the invention according to a so-called particular arcuate trained relief device for the rollers for use arrives.
  • the relief device is preferably in the upper Transition region of the slope positioned in the horizontal and ensures for the rollers to be slightly off their associated track lifted and thus depressurized.
  • On the approximately the contour of the Transition region corresponding arc-like discharge device is running a cooperating with support elements link chain, wherein the Engage support elements in the region of the joints or protective rollers and deflect it upwards.
  • This revolving link chain is preferably made of plain bearing material and is dragged through the step chain.
  • the advantage is in the sheet-like support of the protective roller in the respective support element of Relief device that without relative movement a very small Wear is exposed and compared to conventional solutions as well in the relatively large areal sliding area of the element, thereby Sliding friction on a low surface pressure level allows.
  • the drive system 1 shows the drive system 1 according to the invention as a schematic diagram, including a deflecting element 2 designed as a sprocket and a Drive chain 3.
  • the drive chain 3 includes a plurality of each other connected tabs 4, which are connected to each other via joints 5. Approximately at half height between the joints 5 extend rollers 6, the on stepped bolts 7 with the unrecognizable steps of an escalator in Active compound stand.
  • the deflecting element 2 has chain teeth 8, the adapted the division of the drive chain 3 in a correspondingly reduced manner are.
  • a step tread surface length of 400 mm be accepted.
  • Other parameters with regard to the tread surface length require different chain pitches, respectively numbers of teeth.
  • the chain teeth 8 are provided on the chain side with recesses 9, the Recording the joints 5 are used while the rollers 6 in corresponding Recesses 10 of the deflecting element 2 are positioned.
  • the rollers. 6 in a relatively pressure-relieved form around the deflection element 2 around. This can be done in a simple manner by the recesses 10 larger be designed as the roller diameter, so that selbige only partially or not at all with the corresponding wall portions of the recesses 10 come into contact.
  • Fig. 2a shows a drive system 11, which represents the prior art and used for a heavy duty escalator. Recognizable are steps 12, the provided on stepped bolt 13 with outside the drive chain 14 Casters 15 interact. The step bolts 13 extend here through the joints 16 of the drive chain 14. If assumed Tread length of about 400 mm results in a chain pitch of 133 mm, so that each stage 12 three links of the drive chain 14 are assigned.
  • FIGS. 2b + c show the drive chain 3 according to the invention
  • Drive chain 11 according to FIG. 2 a are the rollers 6 between the joints 5 the drive chain 3 is positioned and above the step pin 16 with the respective stage 12 connected.
  • Fig. 2b shows a drive chain 3 with 200 pitch, i. each level is two Links of the drive chain 3 provided while Fig. 2c a drive chain 3rd with 400 pitch and internal rollers 6 shows that between the Joints 5 of the drive chain 3 are positioned.
  • Fig. 3 shows a relief device 17, for example, in the upper Transition area 18 of an escalator not shown here is arranged. Recognizable is the drive chain 3 together with joints 5 and inside lying rollers 6. The joints 5 are in this example of Schonrollen 19 surrounded.
  • the relief device 17 is arcuate in cross section trained and represents a so-called relief curve, which in An operative connection with a circumferential link chain 20 is.
  • the link chain 20 is in this case entrained by the drive chain 3, i. she is herself drive-free. Between the links of the link chain 20 are so-called Cross-section approximately triangular support members 21 are provided, the on the roller side with corresponding profiles 22 for receiving the same are formed. Characterized in that the support elements 21, the protective rollers 19th record, the rollers 6 in a relieving manner of the individual Limbs of the link chain 20 added, making the straight in this Transition region 18 given increased contact pressure on the rollers. 6 is lowered.
  • FIG. 4 shows a schematic diagram of the drive region 23 of a moving walkway. Visible is the deflecting element 2 and the plurality of links 4 including drive chain 3. The teeth 8 of the deflection element 2 are merely indicated, but can also those of FIG. 1 constructive correspond.
  • the drive motor is provided with the reference numeral 24 and is required, with a gear not shown in Operatively connected. The connection between the drive motor 24 and the Deflection element 2 is ensured by a drive member 25.
  • the Running direction of the drive chain 3 and the deflection of the Deflection element 2 is indicated by arrows.
  • a sensor 28 determines the phase angle of the deflection element 2 and this the To provide control device 27.
  • Another parameter can be the Circulation speed of the drive chain 3 be, for example, via a another sensor 29 is detected and these measurements of the Control device 27 are provided.
  • Frequency converter 26 are now supplied with electrical measurements, that a continuous control of the drive motor 24, for example, on different rotational speeds of the drive chain 3 brought about can be.
