Definitions

  • the invention relates to an elevator system according to the preamble of claim 1 and a combination of termination device and tension element, in particular for elevator systems.
  • An elevator system according to the preamble of claim 1 is known for example from DE 699 33 107 T2.
  • clamping devices are used as termination devices to secure the ends of the rope. These can be, for example, wedge-type clamping devices, compressed chewing or cable locks.
  • the rope is usually a steel cord which has a high compressive strength, so that a high clamping force has no damaging effects on the rope, such as squeezing or creeping.
  • coated tension members comprising a relatively flat tension member.
  • the flat tensile member has a plurality of individual load-bearing strands encased within a common sheath layer.
  • the cladding layer surrounds and / or separates the individual strands.
  • the rope pressure can be distributed more uniformly over the tension element.
  • These flat tension elements are usually flat belts.
  • clamping devices are also used as Closing devices used to attach the ends of the flat belt. These may be, for example, wedge clamping devices or clamping devices in the form of two interconnectable plates.
  • a disadvantage of the use of flat belts is that they have only a low compressive strength, so that a high clamping force can have damaging effects on the tension element, for example a squeezing or a creep, in particular of the cables. Since the contact pressure is usually the same over the entire Werelementbach, the flat belt can be adversely pushed wide. As a result, the outer ropes embedded in the flat belt are disadvantageously more heavily loaded than the inner ones, and the distribution of the pressure over the tension element is no longer uniform. Such a disadvantageous end fastening is described, for example, in WO 01/53186 A1.
  • the object of the invention is to make an elevator system according to the preamble of claim 1 and a combination of termination device and tension element, in particular for an elevator system, safer.
  • the elevator system comprises a car, a counterweight, a relatively flat tension member of a plurality of individual load-bearing ropes, each surrounded by an elastomeric sheath layer and interconnected by a unilateral elastomeric backsheet, for suspending and moving the cab and the Counterweight and a terminating device for securing one end of the tension member, wherein the terminating device has at least two surfaces, between which see the tension element is clamped.

  • the elevator system is made even safer. It has been shown that slipping of the tension element is reliably prevented when clamping the tension element according to the invention in the termination device according to the invention.
  • the tension element according to the invention is securely fixed in the closure device according to the invention, without the risk of lateral tilting or so-called wide squeezing of the tension element.
  • the elastomer which surrounds the individual ropes when clamping due to the inventive design of the tension element and the termination device, can be pressed deep into the ropes. As a result, the pull-out force of the tension element from the termination device is further increased.
  • the elastomer is preferably polyurethane use.
  • the individual ropes are round ropes.
  • the individual ropes are composed of round strands.
  • each recess in its cross-sectional contour substantially corresponds to the cross-sectional contour of each sheathed cable, wherein the cross-sectional contour is preferably U-shaped.
  • the depth a of the recess is smaller than the height b of the cable track.
  • Too small a depth could cause the tension member to be crushed and lose the bonds between the ropes and the elastomer. This would greatly decrease the pull-out force of the tension member from the termination device.
  • clamping surface wherein the wedge is arranged in the base, the at least one clamping surface is adjacent to the jaw surface and the tension member between the clamping surface and the jaw surface is arranged, wherein preferably the clamping surface has the recesses.
