Definitions

  • the invention relates to a rope fixation point for attaching at least one rope according to the preamble of claim 1 and an elevator for conveying at least one load carrier by means of at least one movable in its longitudinal direction rope with a rope fixation point for a rope end of the respective rope.
  • an elevator ropes which are provided for carrying and carrying load carriers (for example, a car or a counterweight), usually held at the cable ends in rope fixing points and between the rope fixing points at least in sections in their longitudinal direction along tracks which by means of a suitable Guide device for the ropes are controlled, movable.
  • the respective cable fixing points can be arranged or fastened, for example, to the ceiling or the floor of an elevator shaft or to a load carrier of the elevator.
  • the guide device usually comprises one or more rollers around which the cables must move during a movement in their longitudinal direction, in particular a drive roller with which traction forces can be transmitted to the cables, and optionally deflection rollers.
  • the ropes are moved in their longitudinal direction during operation of the elevator, then they may at the same time make a rotational movement about their longitudinal direction on the guide device.
  • Rotation of a rope about its longitudinal direction may be caused, for example, on the guide device when the cable on the guide device is under an "oblique" tension (biasing pull) and moved under boundary conditions allowing rotation of the cable about its longitudinal direction. This is the case when the rope is under a tension in its longitudinal direction and thereby guided on a guide surface (for example on the surface of a roller) in a direction which is not parallel but oblique to the longitudinal direction of the rope.
  • diagonal pull may unintentionally occur, for example, when the guide device for the ropes and the rope fixing points during assembly are not aligned so precisely that each cable is guided on the guide device in each case parallel to the pulling direction.
  • diagonal pull is unavoidable - and therefore intended - due to the design of the cable guide.
  • the latter is the case, for example, when a plurality of ropes are each guided side by side over a first roller and subsequently over a second roller, but the axes of rotation of the rollers are not arranged exactly parallel to one another.
  • one of the ropes can be guided so that it is not under diagonal pull.
  • the remaining ropes are inevitably on at least one of the rollers under a diagonal pull.
  • Rotational movements which are introduced into a cable can in turn lead to torsions of the respective cable or individual longitudinal sections of the respective cable around the respective longitudinal direction. This is the case when the rope is not rotated uniformly over its entire length by the same angle during a rotational movement about its longitudinal direction.
  • twists of the cables are associated with torsional moments, which exerts the respective rope on the guide device or the rope fixing points.
  • a longitudinal section of a rope is to be referred to as a "rope section”.
  • a rope usually consists of several tension members, which are "stranded" together.
  • tension members such as strands, which are made of metallic wires and / or synthetic fibers and / or natural fibers - beaten in a (Zugzz-) layer or several (Zug réelle-) layers around a centrally arranged tension members each spirally.
  • the tension members of a tension carrier layer form a periodic arrangement which repeats in the same direction in the longitudinal direction of the rope in each case after a characteristic distance (the "lay length").
  • a rotation of a cable section should be considered here as "turning” when the rotation is associated with a shortening of the lay length of a Ceichevlage in this rope section.
  • a torsional moment which, when introduced into the rope or into a section of the rope, causes a shortening of the lay length, should be referred to as a "twisting" torsional moment.
  • a rotation of a cable section is referred to here as "revolving" when the rotation is associated with an extension of the lay length of a Ceigool.
  • a torsional moment which - initiated in the rope or in a section of the rope - causes an extension of the lay length, be referred to as a "twisting" torsional.
  • Ropes can be damaged by over-tightening or over-tightening of a tension carrier layer.
  • Many rope constructions are particularly sensitive to untwisting a Werner-on-asted Gannarius, in particular with respect to a loosening of the outermost Werner-on-asted Gannarius. For example, if ropes, which are under the action of a tensile load, turned up, then the various tension members are loaded to varying degrees by the tensile load. The most heavily loaded tension members can increasingly degrade and, if necessary, be destroyed. This effect can significantly shorten the life of a rope.
  • rotational movements of the cables should be controlled in such a way that torsions or moments of torsion, which may be introduced into the cables, do not exceed a certain tolerable level.
  • EP1026115 A1 discloses a cable fixation point for fastening at least one cable, which has in each case a cable end attachment for a cable end of the respective cable and a respective rotary mounting for the respective cable end attachment, wherein each rotary mounting comprises a thrust bearing which rotates the respective cable end attachment about a rigid, vertical axis allows.
  • Such rope fixing points are in one Elevator used to fasten the ends of the ropes with which load carriers of the elevator are carried.
  • the thrust bearings ensure that the ropes can freely rotate around the longitudinal direction of the rope-fixing points. In this case, the ropes in the rope fixing points are each held so that no torsional moment is introduced into the respective rope at the rope set points.
  • the latter is intended to cause rotations and / or twists and / or torsional moments, which may under certain circumstances be introduced into one of the cables between the respective cable fixing points - for example when rotating around a traction sheave or pulleys - in the axial bearings of the cable fixing points.
  • rotations and / or twists and / or torsional moments which may under certain circumstances be introduced into one of the cables between the respective cable fixing points - for example when rotating around a traction sheave or pulleys - in the axial bearings of the cable fixing points.
  • the elevator known from EP1026115 A1 has a number of disadvantages when a rope of the elevator fastened to the cable fixation point is guided such that the cable section immediately adjacent to the cable fix point does not run exactly vertically but at a certain angle of inclination with respect to the vertical.
  • the tensile force acting on the rope and thus directed parallel to the longitudinal direction of the rope is introduced at the rope end attachment of the rope in a direction in the rope fixation point inclined by said inclination angle with respect to the vertical.
  • the size of the inclination angle depends under these conditions usually from the current position of the respective load carrier of the elevator and is thus changed in a carriage of the load carrier.
  • the thrust bearing which is connected to the Seilendbefest Trent the rope, loaded radially to the axis of rotation of the thrust bearing.
  • the thrust bearing can wear out quickly under the action of radial forces, unless elaborate countermeasures are taken.
  • the rope is bent at the end of the rope attachment to the side and possibly greatly curved or kinked.
  • the tension members of the rope and possibly other components of the rope eg an outer rope sheath or an intermediate layer arranged between different tension carrier layers
  • a part of the tension members is therefore burdened above average and can therefore degrade faster.
  • the invention has for its object to avoid the disadvantages mentioned and to provide a rope fixation point for attaching at least one rope and a lift for conveying at least one load carrier by means of at least one movable in its longitudinal direction rope with at least one rope fixation point for a rope end, so that rotational movements of the respective Rope are controlled in a gentle way for the rope, even if the rope link point is loaded by a force acting on the rope pulling force whose direction deviates from the vertical and / or whose direction can be arbitrarily specified at least within an angular range.
  • the rope fixation point comprises a Seilendbefest Trent for a rope end of the respective rope and each a pivot bearing for the respective Seilendbefest Trent, each pivot bearing allows rotation of the respective Seilendbefestist about a (rotary) axis.
  • the pivot bearing is constructed so that the axis is alignable by a tensile force acting on the rope.
  • the axis is therefore not rigidly arranged. It automatically changes its direction or orientation when the direction of the pulling force acting on the respective cable is changed.
  • the axis can align under the action of the tensile force such that the component of the tensile force acting radially to the axis becomes minimal.
  • the pivot bearing must therefore be highly resilient only in the direction of the respective tensile force.
  • the respective rope if it is offset at the cable link point in a rotation about its longitudinal direction, only minimally stressed by bending change.
  • the axis can be aligned in the direction of a tensile force acting on the rope and / or in the longitudinal direction of a rope section adjoining the rope tie point.
  • This has the advantage that the pivot bearing is not claimed by any forces acting radially to the axis and therefore can be realized with particularly simple means.
  • the respective rope if it is offset at the cable link point in a rotation about its longitudinal direction, claimed at the cable link point not at all by bending or bending change.
  • the pivot bearing can be realized in various ways within the scope of the invention.
  • the pivot bearing may comprise a thrust bearing having a part rotatable about the axis, the rope end mounting being connected to the rotatable part.
  • the pivot bearing may comprise a pivoting mechanism for the thrust bearing for aligning the axis within an angular range.
  • the pivoting mechanism allows pivoting of the thrust bearing in its entirety, the thrust bearing can have an axis of rotation that is immovable (i.e., oriented in a given direction) with respect to the thrust bearing.
  • Such thrust bearings are particularly simple to implement with standard components, for example as Axial anymorelzlager or Axialgleitlager.
  • the pivot mechanism may include a hinge for pivoting the thrust bearing about a point or hinge for pivoting the thrust bearing about a pivot axis or hinge for pivoting the thrust bearing about a first pivot axis and about a second pivot axis not disposed parallel to the first pivot axis.
  • Such hinges allow the axis to be aligned by pivoting in one dimension through an angle within a predetermined angular range or aligning the axis in two dimensions within a predetermined solid angle range.
  • a joint that allows pivoting in two dimensions in this context has the advantage that the cable link point does not have to be precisely aligned during assembly, since the axis of the pivot bearing self-aligns with respect to the direction of the tensile force within a solid angle range.
  • the thrust bearing can be designed as Axialpendellager, the rotatable part is mounted pendulum.
  • the axis of rotation of the thrust bearing is not rigidly aligned relative to parts of the thrust bearing, but within a predetermined angular range or solid angle range aligned.
  • An additional one Swing mechanism for pivoting the thrust bearing in its entirety is therefore not required in this embodiment.
  • the rope fixation point comprises means for controlling a torsional moment acting on the rope at the end of the rope.
  • the rope is held rotatably on the rope fixation point, but not kept freely rotatable.
  • Rotations of the rope can be controlled with the means mentioned so that the rope initiates a torsional moment in the pivot bearing whose size is within predetermined limits.
  • the means may for this purpose comprise, for example, a braking device for braking a rotational movement of the cable and / or a drive for transmitting a torsional moment to the rotatable part and / or to the cable end attachment and / or to the cable.
  • the rotational movements of the rope at the rope fixation point are controlled so that the rope is held at the rope fixation point under a twisting torsional moment.
  • the rope - should it not be rotation-free - does not turn up under the tensile load.
  • the torsional moment acting on the cable at the cable fix point does not exceed a predetermined limit. In this way, ropes can be kept gentle, which are not rotation-free.
  • the rope fixation point according to the invention can be used in an elevator for conveying at least one load carrier by means of at least one rope movable in its longitudinal direction, wherein the rope fixation point serves for fastening a rope end of the respective rope and the respective rope is under tensile force at the rope end whose direction is dependent is changeable from a position of the load carrier.
  • the construction of the cable hinge point ensures that the axis of the rotary bearing is aligned by the tensile force, for example in the respective direction of the tensile force and / or in the longitudinal direction of a cable section adjacent to the cable hinge point.
  • the axis of the pivot bearing is automatically aligned so that rotational movements of the rope are controlled in a manner as gentle as possible for the rope.
  • the rope fixing point does not have to be arranged very precisely during assembly, since the axis of the pivot bearing optimally aligns under the effect of the tensile force anyway.
  • Fig. 1 shows a lift 1 for conveying at least one load carrier with at least one movable cable connected to the respective load carrier.
  • FIGS. 2-7 illustrate various details of the elevator 1.
  • the elevator 1 comprises two load carriers which can be transported by a cable 7: an elevator car 3, which is guided on guide rails 4 in the vertical direction, and a counterweight 5, which is guided on guide rails 6 in the vertical direction.
  • the cable 7 has two cable ends 7 ', 7 ", which in each case at a cable fix point 12 or 13 are arranged rotatably about an axis L 12 and L 13 .

  • the drive roller 20 and the guide rollers 11.1, 11.2, 11.3 influence the path which follows the cable 7 during its movement in its longitudinal direction.
  • the drive roller 20 and the guide rollers 11.1, 11.2, 11.3 thus form a guide device for the cable 7: serve as guide surfaces, the areas of the surfaces of the rollers 11.1, 11.2, 11.3 and 20, with the cable 7 when driving the car 3 in Contact advised.

Due to the rotation of the drive roller 20, the cable 7 is moved in its longitudinal direction, i. moved in the direction of the arrows 31 and guided along the surface of the drive roller 20 through the groove 21. Furthermore, it is assumed that the cable 7 - due to the relative arrangement of the drive roller 20 and the groove 21 with respect to the guide rollers 11.1, 11.2, 11.3 on the elevator car 3 and the counterweight 5 - is not performed exactly parallel to the plane 27.

  • the drive 80 is controlled by means of the control device so that the cable section 7.1 at the rope fixation point 12 or the rope section 7.5 at the rope fixation point 13 is under a torsional moment, which is directed so that it on the cable section 7.1 or on the cable section 7.5 zufitend acts, and its size is limited so that the rope 7 is not damaged. In this way, the cable section 7.1 or the cable section 7.5 can be kept under a twisting torsional moment.
  • the drive 80 can be regulated, for example, so that the torsional moment acting on the cable section 7.1 or the torsional moment acting on the cable section 7.5 during operation of the elevator 1 is constant.
