Definitions

  • the invention relates to a traction device with at least two individual ropes, in particular for an elevator installation, wherein the traction means can be driven by a traction disk with grooves and an elevator installation with a traction means.
  • each individual rope is uniquely assigned its own rope groove on the traction sheave. Each rope dives at least in part of its diameter in the associated cable groove. Each individual rope is an independent tension element and can also be operated individually. For higher outputs, either several ropes can be used in parallel, or the rope diameter is increased accordingly.
  • the single rope is thus not only traction means for transmitting the tensile forces, but is also directly involved in the transmission of traction forces.
  • Ropes have the advantage over belt technology that the force can be transmitted directly from the traction sheave to the ropes.
  • the transmission of traction forces from the traction sheave to the traction means takes place here via the friction between traction disk and elastomer material, the traction forces then being transmitted to the traction elements via shear stresses in the elastomer material and the adhesive mechanism between elastomer material and traction elements.
  • the material properties, especially the shear strength of the elastomeric material therefore play a decisive role in this case.
  • the introduction of force into the individual tension elements thus takes place indirectly.
  • the tension elements themselves are thus responsible only for the transmission of tensile forces.
  • EP 1 396 458 A2 describes an elevator device in which a flat belt of elastomeric material reinforced with reinforcements is used as the traction means.
  • EP 1 555 234 B1 shows an elevator installation with a V-ribbed belt.
  • Belts offer over the ropes the advantage that on the one hand the handling is easier, because not individual ropes must be placed on corresponding grooves of the traction sheave, and that also small traction sheave diameter can be used without problems, since the embedded tension members usually have relatively small diameter.
  • belts as traction means are virtually maintenance-free, since no lubrication is required.
  • the transferable force is, as already described above, in addition to the friction between the traction sheave and elastomer also on the shear strength of the elastomer and the quality of the embedding of the tension members in the elastomer, ie, the adhesion between the elastomer and tension member dependent. The importance of the material properties of the elastomer increases with increasing distance of the tensile carriers from the force application zone.
  • a synthetic fiber rope is disclosed in EP 1 061 172 B1, in which two cables folded in opposite directions are connected to form a twin rope via an elastomer jacket surrounding the cables. Between the individual ropes in each case a kind of web is arranged, which is intended to prevent the twisting of the ropes as a torque arm. In operation, it may happen that a relative movement of the individual ropes is created by different expansion behavior of the individual ropes to each other. This can lead to the cables being released from the adhesive bond with the surrounding elastomer material if the connection of the individual cables is designed as a relatively solid web.
  • EP 1 728 915 discloses a teaching for avoiding the above-mentioned cases of damage, in which the individual cables are connected to one another, as it were, by a positive locking connection, so that a certain relative mobility of the individual cables relative to one another is possible.
  • this design requires complex manufacturing and assembly processes.
  • the invention has for its object to provide a traction device of the type described, which is easy to handle, with high tensile forces are transferable, the traction means over the known belt technology allows a less broad-based drive unit and which is insensitive to relative movements of the individual ropes to each other.
  • the traction means is formed as a composite rope, in which the parallel individual cables are sheathed with a first diameter, each with an elastomer layer of a predetermined thickness to tensile carriers, each with an overall diameter and the tension members by elastomeric connectors substantially over their entire Length are interconnected, the tensile carriers each engage at least 25% of their total diameter in the grooves of the traction sheave and the elastome- ren connectors are designed such that they are so easily separable relative movements of the tension members so that this is the connection of the individual cables the elastomer layers of the individual tension members not impaired.
  • Such a behavior of the connector can be achieved, for example, by the choice of a suitable elastomer, but also by a predetermined, correspondingly small thickness of the connector.
  • the connectors serve as an assembly aid, since the composite rope thus connected from individual tension members is very easy to handle.
  • Another advantage of the composite cable according to the invention is that a separation of the connector after assembly by relatively low forces of the composite elastomeric coating and individual cables to the individual tension members is not affected. Since a composite rope in operation acts like a plurality of individual tension members by the individual tension members each engage at least 25% of their diameter in a separate groove of the traction discs and therefore the connectors for traction Transmission contribute only a negligible part, the composite rope remains fully functional even when disconnecting the connector after assembly.
  • the composite rope is so easy to handle and is almost maintenance-free like a belt. Due to the directly engaging in the grooves of the traction sheave tension member is given a high power transmission. The zone of power transmission between traction sheave and traction means lies directly in the engagement zone. Due to their small thickness, the shear strength of the sheath is of very little importance.
  • Thin ropes can be used so that small traction disc diameters and narrow traction discs are possible. For each compound rope only one connecting element for connection to the example to be lifted elements is necessary.
  • the thickness of the sheathing of the individual cables in the range of 0.2 - 2 mm.
  • the thickness of the sheathing of the individual cables in the range of 0.5 - 1 mm.
  • the ratio of the diameter of the individual cables to the thickness of the sheathing u d / u is greater than or equal to 3.
  • the thickness of the casing is so thin in relation to the diameter of the individual ropes that the properties of the casing play a particularly small role.
  • the sheath is formed of an elastomer which differs from the elastomer of the connector layer.
  • the elastomer or the elastomers is preferably a polyurethane or polyurethane.
  • Polyurethane has both good friction and good adhesion properties and is relatively insensitive to shear.
  • the sheathing of the individual cables has an outer contour facing the traction sheave whose cross-section is deviating from a partial circle shape.
  • the cross section of the outer contour is trapezoidal.
  • the cross section of the outer contour is square.
  • the cross section of the outer contour is conical.
  • the configuration of the cross sections of the casing in different geometries has the advantage that the composite rope is therefore adaptable to a large number of traction disk profiles.
  • each composite rope has at least four individual cables.
  • the individual cables are arranged alternately between S and Z impact.
  • the number of individual ropes per compound rope is even.
  • the individual cables are made of steel.
  • the diameter of the individual ropes is between 1, 5mm and 8mm.
  • the diameter of the individual cables is between 1.8 and 5.5 mm.
  • adjacent tensile carriers are at least partially combined in groups to at least two tension members such that the Glasierigrup- pen each engage in a common corresponding groove of the traction discs.
  • the side of the composite cables facing away from the traction sheave has a cover coating.
  • the side of the composite cables facing the traction sheave has a cover coating.
  • the cover coating is formed from a flat textile, for example a fabric.
  • the traction means is formed as a composite rope, in which the parallel individual cables are sheathed with a first diameter, each having an elastomer layer of a predetermined thickness to tensile carriers, each having a total diameter, the tension members by elastomeric connectors substantially are interconnected over their entire length, the tensile carriers so engage in the grooves of the traction discs, that the immersion depth of the individual cables of the tension members in the grooves of the traction discs at least 25% of the diameter of the individual ropes and the elastomeric connectors are designed such that they are in relative movements the tension members are so easily separable from each other, so that this does not affect the connection of the individual ropes with the elastomer layers of the individual tension members.
  • the advantageous developments according to the dependent subclaims of the invention according to the main claim also make the solution of the problem according to the independent claim advantageous and are therefore also based on the secondary claim.
  • the invention is further based on the object to provide an elevator system whose traction means over the said prior art, a further reduced width of the traction disc allows and play in the properties of elastomeric materials only a minor role.
  • Such an elevator system has the advantage that on the one hand the assembly is facilitated due to the good handling of the composite cables according to the invention, on the other hand, no wide-build traction drum is required.
  • Fig. 2 shows a composite rope
  • the sheathing of the individual ropes has a deviating from the circular geometry
  • the composite rope 1 shown in cross-section in FIG. 1 has five individual cables 2, which are each encased in a jacket 3 made of an elastomer.

  • FIG. 2 shows a composite cable 6 whose casing 3 of the individual cables 2 has a geometry 7 deviating from the circular shape. Again, the tension cords 4 are interconnected by connector 5.
