Definitions

  • the present invention relates to a suspension device for a lift installation, by means of which suspension means, such as ropes or belts, which hold, for example, an elevator car or a counterweight, for example, can be fastened to a support structure or the elevator car.
  • suspension means such as ropes or belts, which hold, for example, an elevator car or a counterweight, for example, can be fastened to a support structure or the elevator car.
  • Elevator systems are typically used to carry persons or loads in the vertical direction, for example between floors of a building.
  • an elevator car is regularly provided, which by means of a drive unit, e.g. within an elevator shaft along one or more guide rails can be moved.
  • the elevator car is typically connected to the drive unit via suspension elements, so that the drive unit can move the elevator car held thereon by moving the suspension elements.
  • the drive unit has, for example, an electric motor which drives a traction sheave, which in turn drives the suspension element in the form of a belt or rope running over the traction sheave, whereby the elevator car held on the suspension means is moved.
  • a counterweight is additionally provided in the elevator system, which is held at or near an opposite end of the suspension element.
  • a plurality of support means are usually provided for safety reasons or for reasons of suitable load distribution in order to be able to hold and move the elevator car and / or the counterweight.
  • ends of the suspension elements are usually attached to a support structure of the elevator installation. Between these ends the suspension means hold the elevator car and / or the counterweight by e.g. slip underneath the entire component or be wrapped around attached deflecting discs.
  • the suspension elements may also be fastened with their ends to the elevator car and / or the counterweight and may be held in a looping manner in intermediate areas on one or more deflection rollers fastened to the support structure.
  • An attachment of the support means to the support structure of the elevator system or to the elevator car and / or the counterweight should meet several requirements.
  • the attachment should be able to safely and reliably support a force necessary to hold the elevator car and / or the counterweight ultimately on the vehicle Carrier structure of the elevator system to transfer.
  • the attachment should be made mechanically stable suitable to transfer the maximum occurring forces without damage and possible wear on the support structure.
  • the attachment should be designed such that, for example, bending moments can be avoided or kept as low as possible on the support structure.
  • the attachment should also be designed to tolerate or compensate for changes that may occur during the operation of the elevator installation within the elevator installation. For example, in the course of operation of the elevator system, temperature fluctuations may occur, which among other things may lead to changes in the lengths of the suspension elements. Also, different mechanical stresses or different mechanical interpretations of the support means can cause individual or multiple support means change in length over time. The attachment should be able to provide despite such changes in length of support means for their reliable attachment to the support structure of the elevator system.
  • suspension device suspension apparatus for an elevator system which has been advantageously developed with respect to prior art suspension suspension devices.
  • a suspension device for a lift installation has a rocker device, which is designed to hold an elevator car of the elevator installation on a support structure via at least two suspension elements acting on the suspension element suspension device.
  • the luffing device has a holding arm structure with an elongate main holding arm, a central fastening arrangement and at least one deflection roller.

  • the traction sheave of the support means driving drive each of the support means drive different degrees, eg due to locally slightly varying diameters of the traction sheave, so at least in front of and behind the traction sheave located portions of suspension elements different length changes can occur.
  • the support means extends in a looping manner over the guide roller attached to the guide roller and is fastened with its ends, for example, in another area within the elevator installation to a support structure. If there are length changes in this suspension element, they can be at least partially compensated for by the fact that the suspension element wrapping around the deflection roller rotates the deflection roller and displaces a region of the suspension element with which it is looped around the deflection roller and holds the deflection roller.
  • the deflection roller can be rotated by more than 90 ° and thus potentially compensate for large differences in length in the suspension element wrap around them.

  • the pulleys may be disposed on the main support arm at equal intervals to the mounting arrangement.
  • the two pulleys can have an identical diameter.
  • suspension means can be the same.
  • both suspension elements can be looped around the deflection pulleys in identical radii of curvature and thus radii of curvature and therefore be subjected to the same wear caused by the curvature.
