Definitions

  • the invention relates to a suspension element according to the preamble of claim 1 and an elevator for conveying at least one load with such a suspension element.
  • Supporting means used in an elevator for carrying loads typically have a hull comprising at least one strand of a plurality of mutually stranded or braided tension members and extending in the longitudinal direction of the suspension element.
  • the suspension elements are usually guided transversely to their longitudinal direction.
  • an elevator with a rope which has a round cross-sectional area with a width A and a height B with a ratio A / B equal to 1 in the unloaded state or near 1 in a loaded state.
  • the cable is guided on the periphery of a traction sheave in a guide groove with a semicircular cross section and can rotate about its longitudinal axis under the influence of torsional moments in the guide groove.
  • WO 99/43589 shows an elevator in which a flat belt is used as the carrying means for carrying loads.
  • the belt comprises a plurality of mutually stranded tension members, extending in the longitudinal direction of the support means, arranged parallel to each other strands and a casing surrounding the strands.
  • the belt has a rectangular cross section whose outline has a width A and a height B with a ratio A / B greater than 1.
  • the belt is guided transversely to its longitudinal direction in each case in guide grooves, which are formed on the periphery of a traction sheave or the periphery of rollers and have a rectangular cross-section.
  • the belt is arranged so that it rests with its broad side respectively on the bottom of the respective guide groove.
  • a preferred embodiment of this belt has a cross section for which the ratio A / B is substantially greater than 1, for example A / B> 4. In this case, the belt is significantly wider than high.
  • the leadership of such a belt is complicated by the fact that arise in a circulation of the belt around the traction sheave or the rollers relatively strong disturbing forces which may fluctuate and act on the belt across its longitudinal direction and parallel to the wide side of the belt. Such disturbing forces act to destabilize the guidance of the belt and may cause the belt in a guide groove to make a fluctuating sideways movement toward the flanks of the guide groove.
  • the belt can be repeatedly pressed in this way in the guide grooves against the flanks of the guide grooves and thereby deformed. In this way, the wear of the belt can be drastically increased. Under the influence of the disturbing forces, the belt may possibly travel over the flanks of a guide groove and leave the guide groove. It may therefore be a problem to reliably hold the belt in the respective guide grooves.
  • the object of the present invention is to avoid the disadvantages mentioned and to provide a support means and a lift for conveying at least one load with such a support means such that the support means can be guided reliably transversely to its longitudinal direction and an excessive rotation of the Supporting means can be avoided around its longitudinal direction.
  • the support means has a hull which comprises at least one strand of a plurality of stranded or braided tension members and extends in the longitudinal direction of the support means.
  • at least one guide body is fastened to the hull, which guide body extends in the longitudinal direction of the suspension element and projects laterally from the hull.
  • the respective guide body can be dimensioned such that a region extending in the longitudinal direction of the fuselage is available on the surface of the fuselage adjacent to the guide body and can be brought into contact with suitable guide means so as to transversely cross the suspension element during a movement in its longitudinal direction lead to the longitudinal direction. Since the guide body is attached to the hull, the guide body would also perform a rotation about the longitudinal direction of the support means upon rotation of the support means about its longitudinal direction. By virtue of the fact that the guide body projects laterally from the fuselage and extends in the longitudinal direction of the suspension element, such rotational movement of the guide body can be kept within predetermined limits by means of a suitably arranged guide device be prevented. Since the guide body is attached to the hull of the support means, in this way a rotation of the support means about its longitudinal direction can be kept within predetermined limits or prevented.
  • the suspension means can be used, for example, in an elevator for carrying loads as follows.
  • the support means may be connected to the respective load and arranged to be movable in its longitudinal direction and the hull of the suspension means is brought into contact with at least one fuselage guide surface for guiding the suspension means transversely to its longitudinal direction.

  • the hull of the suspension element can also comprise more than one strand of a plurality of mutually stranded or braided tension members.
  • the guide body may be attached directly to a strand or possibly to a plurality of strands.
  • the surface of the respective hull may be formed by a jacket which encloses the respective strands.
  • the respective guide body may be attached to the jacket.
  • the jacket and the guide body are integrally formed. This variant is advantageous in terms of production.
  • the jacket and the respective guide bodies can be produced, for example, from the same material and in particular together in a single production step.
  • materials and methods are suitable, which have already proven in the production of coats for conventional ropes.
  • plastics, polymers, elastomers or thermoplastic materials are suitable.
  • the guide body and / or the jacket can also be provided in each case with at least one reinforcing element for mechanically reinforcing the guide body.
  • the support means comprises two guide bodies extending in the longitudinal direction of the support means, projecting laterally from the fuselage and arranged to be separated at a surface of the fuselage by a gap and / or disposed on opposite sides of the support means ,
  • a strip-shaped area is formed, which extends in the longitudinal direction of the guide body.
  • This area of the fuselage can be brought into contact with a fuselage guide surface to guide the suspension means transversely to its longitudinal direction.
  • a guide device for limiting or preventing a rotation of the suspension element about its longitudinal axis can be provided for both guide bodies. This configuration has the advantage that rotations of the suspension element in both a direction of rotation and in the opposite direction of rotation can be limited or prevented by simple means.
  • a guide device for the respective guide body can be realized according to the invention in several variants.
  • the guide device for the respective guide body comprises a mechanical stop.
  • the mechanical stop is arranged on the suspension element such that rotation of the suspension element about its longitudinal direction in a predetermined direction of rotation is limited or prevented by a mechanical contact between the stop and the guide body, at least in the region of a longitudinal section of the suspension element.
  • the guide device for the respective guide body comprises two mechanical stops.
  • the two mechanical stops are arranged with respect to the guide body such that the guide body is guided between the two mechanical stops and a rotation of the support means about its longitudinal direction in a first rotational direction at least in the region of a longitudinal portion of the support means by a mechanical contact between the guide body and one of Stops and a rotation of the support means about its longitudinal direction in the direction opposite to the first direction of rotation at least in the region of Longitudinal section of the support means is limited or prevented by a mechanical contact between the guide body and the other of the stops.
