Definitions

  • the present invention relates to a suspension element end connection for fastening one end of a suspension element in an elevator installation, to an elevator installation with suspension element end connection and to a method for fastening one end of a suspension element in an elevator installation.
  • An elevator system usually consists of a car and a counterweight, which are moved in opposite directions in an elevator shaft.
  • Cab and counterweight are connected and supported by means of suspension.
  • One end of the suspension element is fastened with a Tragstoffend für to the cabin, or at the counterweight or in the elevator shaft.
  • the suspension element end connection accordingly has to transmit the force acting in the suspension element to the car or the counterweight or to the elevator shaft. It must be designed so that it can safely transmit a required load capacity of the suspension element.
  • Today more suspension means are used in which several ropes or rope strands are joined together to form a suspension.
  • the support means consists of at least two spaced apart ropes or rope strands and a common cable sheath.
  • the ropes or rope strands serve essentially to transmit carrying and movement forces, and the cable casing protects the cables, or the cable strands, from external influences and improves the transmission capability of drive forces which are introduced into the suspension elements by drive machines.
  • the support means is held by a wedge in a wedge pocket.
  • WO 00/40497 is a Tragstoffenditati for an elastomeric sheath provided suspension means known.
  • the elastomeric sheath envelopes and / or separates the individual ropes or rope strands and defines a force transmission surface to the prime mover.
  • a wedge angle is to be selected such that the pressure load generated by the wedge, given a given length and width, on the suspension element causes smaller values than the permissible pressure loading of the elastomeric envelope.
  • the coefficients of friction within a wire rope or a rope are in many cases less than from the cable sheath to the connecting parts. As a result, a wire rope or a rope is held only insufficiently within the cable sheath, whereby the permissible load capacity of the suspension element is limited.
  • Object of the present invention is to provide an optimized Tragstoffenditati, which maximizes the carrying capacity of the support means and safely transmits.
  • This has the advantage that a cost-effective elevator installation can be provided.
  • the force transmission into the supporting ropes or rope strands can be ensured, the overall stresses in the suspension element can be optimized and a long service life of the suspension element can be achieved.
  • the suspension means end connection can be made resistant to elevated ambient temperatures and can be easily mounted.
  • the invention relates to a suspension element end connection for fastening a suspension element end in an elevator installation and to a method for fastening a suspension element in an elevator installation according to the definition of the claims.
  • the elevator system consists of a car and a counterweight, which are moved in opposite directions in an elevator shaft. Cab and counterweight are connected and supported by means of suspension.
  • the support means consists of at least one rope or rope strand and a cable sheath which encloses the rope or the rope strand.
  • the rope or the rope strand is made of optionally impregnated synthetic fibers or of metallic material, preferably steel wires. Several of these support means together form a suspension element strand.
  • the suspension element is fastened to the car or counterweight or in the elevator shaft by means of a suspension element end connection.
  • the suspension element is held in the suspension element end connection by means of a wedge which fixes the suspension element in a wedge pocket.
  • the wedge-containing part of the TragstoffendENS is formed by a wedge housing.
  • the support means has at its unloaded end on a loose Trumm. This loose strand runs on a, inclined to the vertical direction, Keiltaschenhaft Structure and is there pressed by the wedge, by means of its wedge adhesion surface on the Keettaschenhaft materials.
  • the support means is further guided around a wedge arc and extends between a mutual Keilgleit phenomenon and the Keiltaschengleit Structure, which is oriented substantially vertically, or in the pulling direction of the support means to the supporting run of the support means.
  • the support means wraps around the wedge.
  • the tensile force of the suspension element is thus applied by a pressure along the wedge and wedge pocket surfaces and the wrap of the wedge.
  • the support means is held by the wedge in the wedge pocket and the support means extends between the wedge and wedge pocket.
  • a tolerable tensile force of the suspension element is significantly influenced by the design of the contacting surfaces and the type of power flow from the Tragstoffendthetic to the sheath and the ropes, or the rope strands.
  • the rope, or the rope strand is adhesively bonded, fused or mechanically connected in the regions of the suspension element end connection to the cable sheath.
  • the bonding, merging or mechanical connection of the rope, or the rope strands with each other and with the cable sheath causes no relative movement can take place within the suspension means.
  • a frictional force which is transmitted from the surfaces of the key pocket or the wedge to the cable sheath is forwarded directly into the load-bearing core of the suspension element, to the cables or rope strands.
  • the sustainable tensile force in the suspension element is increased.
  • Bonding takes place, for example, by dropping or pouring a predefined amount of low-viscosity adhesive at the end of the suspension element into the individual ropes or cable strands. Due to the force of gravity and capillary action, the adhesive pulls in between the rope or rope strand and the sheathing and permanently bonds these parts.
  • the adhesive in particular also combines with the impregnating agent, for example polyurethane.
  • the adhesive should have a sufficiently low surface tension. This bond forms a cost effective method for producing a Tragstoffendbefest Trent.
  • a fusion can take place by means of a heat source from the outside, or via a source of ultrasound a selective fusion of the cladding material with the ropes, or the rope strands done.
  • a fusion when using similar materials such as polyurethane, in the Seillitzenim Weggntechnik and the coat.
  • a mechanical connection is made by, for example, a pin is inserted into the end of the rope or rope rope, which increase the local pressures.
  • a pin is inserted into the end of the rope or rope rope, which increase the local pressures.
  • This version is particularly cost-optimal and the wood screw causes an increase in the sustainable pull-out force in two respects.
  • the local pressure is increased and, on the other hand, the head of the wood screw is attached to the housing or the wedge in the event of slippage. This increases the sustainable pull-out force.
  • Another mechanical connection can also be achieved by a knotting or intertwining the ends of the rope strands, or ropes of the suspension element.
  • This compound is preferably used for thin and correspondingly flexible cables or rope ends
  • the cable sheath consists essentially of thermoplastic or elastomer.
  • An advantageous embodiment provides that a wedge adhesion surface or Keiltaschenhaft Construction closer to the loose Trumm of the support means is provided with a Lfitskeilrille.
  • This is particularly advantageous because under load of the support means resulting from the drawing of the wedge pressing force of the wedge on the wedge pocket in particular increases the possible retention force in the support means on the side of the Keiltaschenhaft materials and the rope, or the rope seats with each other and with the cable sheath compresses - since this surface has Lfitskeilrillen -, whereby the max. possible Tragstoffstoff, as a result of the deflection around the wedge arch, increased.
  • the power is continuously increased, as the increase in power is further built on the side of the loose Trumms.
  • the key groove can be made over the arch of the wedge.
  • the looseness of the support means closer Keettaschenhaft Chemistry and / or wedge adhesion surface is provided with a relation to the remaining surface of the wedge pocket, or the wedge increased roughness, or these surfaces are provided with transverse grooves or transverse grooves.
  • the loose run of the suspension element is held securely and it can be transmitted a high load capacity.
  • the Keiltaschengleit Structure on which the support member slides during the loading process designed with a corresponding lower roughness, which counteracts damage to the suspension element, since its surface is not damaged.
  • a wedge sliding surface and / or wedge pocket sliding surface which is closer to the supporting run of the suspension element is provided with coefficient of friction reducing measures.
  • Reibwertreduromizingde measures are for example a sliding spray, an intermediate layer of lubricious plastic or a surface coating. This allows a sliding of the support means during the loading process which counteracts damage to the support means on the tensile side of the TragstoffendENS because its surface is not injured and a load in the jacket and rope or rope rope is uniform.
  • a low-cost Tragstoffendthetic can be provided with high load capacity.
  • a wedge sliding surface or wedge slipper sliding surface closer to the supporting run of the suspension element has a first and a second surface area, wherein the first surface area is arranged at the zone of the outlet of the suspension element from the suspension end mounting and this first surface area has a larger wedge angle than the wedge sliding surface second surface area, which adjoins the first surface area and which forms the transition to a further surface area or to the upper end of the wedge pocket surface or the wedge surface.
  • the first surface area moves away towards the outlet side wedge end increasingly from the corresponding counter surface.
  • the transitions between the individual surface areas continuously executed.
  • the surface regions are designed in such a way that a transition from the first to the nth surface region runs continuously, ie according to a transitional contour, wherein the nth surface region determines the main pressing region.
  • the first surface area extends over less than 50% of the total wedge or Keetaschengleit Chemistry.
  • the suspension element undergoes no sudden load transitions. This increases the service life of the support system.
  • the zugseilnessen ends of the Keilgleit evaluation and the Keiltaschengleit configuration are advantageously provided with radii or curved.
  • the use of a radius or curved transitions causes a pressure of the suspension element to be gradually built up. There are no forced changes in tension forced and a sliding of the support means in the highly loaded tensile zone of the support means is made possible without damaging the support means.
  • the wedge is designed to be resilient at its wedge-shaped end. This leads to a slow reduction of the pressing force of the suspension element. Also by the suspension means undergoes no sudden load transitions. This increases the service life of the support system.
  • the wedge adhesion surface of the loose strand is connected to the wedge sliding surface of the supporting run at the upper end of the wedge by means of the wedge arc and this wedge arch connects tangentially to the two-sided wedge surfaces
  • the radius of curvature of the bow to the wedge adhesion surface of the loose strand gets smaller.
  • a smaller radius of curvature causes a greater curvature of the support means and thereby indexed greater deformation stresses in the support means itself.
  • the tensile force acting in the suspension means according to the Eytelwein'schen Umschlingungs must from loose Trumm down, which causes decreasing tensile stresses in the suspension element.
  • Increasing deformation stresses thus face decreasing tensile stresses and ideally compensate each other. This causes an optimization of the total stress in the suspension element and extends the life of the suspension element as a whole.
