Definitions

  • the invention relates to an elevator system with at least one car movable in a shaft, which is connected via two cable strands, which are assigned to different sides of the car, with a counterweight, and with a motor-driven traction sheave, over which the two cable strands are guided, wherein the Car is kept in a suspension ratio of 1: 1.
  • Such elevator systems are from the EP-A-1 329 412 known.
  • This elevator system two in a shaft independently upwards and downwards movable cars are used.
  • the upper car is connected to a traction sheave and a counterweight via a single, multi-strand cable harness. Starting from this counterweight, the rope strand is then guided to a traction sheave of the lower car, and then the rope strand is divided into two rope strands, which run at a distance from each other and each associated with one side of the lower car.
  • the lateral arrangement of the two cable strands of the lower car makes it possible to guide the cable strands each on one side of the upper car, which occupies a position between the two strands of rope.
  • a separate drive is used, which is coupled to the respective traction sheave and causes it to rotate.
  • the different expansion behavior of the two cable strands is not negligible.
  • the car is maintained in a suspension ratio of 1: 1, so that the change in height of the car is identical to the feed of the cable strands and consequently there is no relative movement between the cable strands and the car.
  • Object of the present invention is to develop an elevator system of the type mentioned in such a way that a different elongation behavior of the two cable strands can be compensated.
  • the cable length compensation device By means of the cable length compensation device, a different elongation behavior of the two cable strands can be compensated, in particular larger, resulting in operation of the elevator system length differences of the two cable strands can be compensated despite the suspension ratio of 1: 1 with a cable guide the rope strands on two different ways.
  • the two cable strands are loaded in the elevator installation according to the invention with the same tensile force, so that sets for both cable strands practically the same friction behavior in the range of the traction sheave. In addition, a tilt of the car is avoided.
  • the rope length compensation device can be positioned on the car or on the counterweight. It can be arranged, for example, above or below the car or the counterweight.
  • the car is both a user-accessible car cabin without a car frame and a car cabin including a car frame, on which the car cabin is held.
  • the cable length compensation device has two connecting members, via which the two cable strands are operatively connected to the car or the counterweight, wherein the cable strands are coupled together between the two connecting members or via the two connecting members.
  • the cable strands each act on a connecting member which is associated with the respective cable strand.
  • the link is disposed adjacent to a plane defined by the side of the car or counterweight to which the respective cable strand is associated.
  • the rope strands comprise several single ropes.
  • the connecting members comprise a plurality of connecting elements, wherein each individual cable is assigned a connecting element and individual cables of the two cable strands between the respective connecting elements or via the respective connecting elements are coupled together.
  • Such a configuration has the advantage that a rope length compensation and thus a train compensation is made possible between individual ropes of the two cable strands, so that a different elongation behavior of the individual ropes can be compensated.
  • a locking device is arranged between the connecting links for non-displaceable mounting of the cable strands relative to the car or to the counterweight.
  • Such a configuration makes it possible to prevent a cable length compensation in the presence of certain operating conditions of the elevator system, for example in the presence of a malfunction.
  • an immovable mounting of the two cable strands relative to the car or the counterweight can be ensured by means of the locking device.
  • the locking device can be deactivated, so that a rope length compensation is possible during normal operation of the elevator system.
  • the locking device may for example comprise a cable clamp with which the cable strands can be fixed immovably on the car or on the counterweight.
  • the connecting links at least one cable tension compensation element is assigned to compensate for the rope strands prevailing rope tensions.
  • the cable tension compensation elements can be counteracted in addition to the compensation of the rope lengths directly a difference in the rope tensions by the rope tension is increased in the one strand of rope and reduced in the other strand of rope.
  • the cable strands have a plurality of individual cables, then it is particularly advantageous if a plurality of cable tension compensation elements are assigned to the connecting elements to compensate for the cable stresses prevailing in the individual cables. This can be ensured in a structurally simple manner that the individual cables of a rope strand have virtually the same cable tension and therefore loaded in the same way and are not overloaded.
  • the at least one cable tension compensation element can interact in different ways with at least one cable strand and a connecting member.
  • a cable tension compensation element is arranged between a cable strand and a connecting link.
  • a cable tension compensation element is arranged between a connecting link and the car or the counterweight.

  • the links can hereby be movably held on the car or on the counterweight be, so that by moving at least one link, a difference in the pitches of the two cable strands can be compensated.
  • the cable length compensation element has a linear adjustment system, for example a linear drive element, in particular an electrical, mechanical, hydraulic or pneumatic drive element for a linear (linear) movement, for example a hydraulic or pneumatic piston-cylinder unit.
  • a linear adjustment system has the advantage that by means of an electric, mechanical, hydraulic or pneumatic adjusting actively a difference in the cable lengths of the two cable strands can be counteracted by the linear adjustment is activated according to a present pitch difference and thus extended or shortened.
  • the connecting members are spaced from each other and the two cable strands are preferably integrally connected to one another between the connecting members.
  • Such a configuration makes it possible to guide the interconnected cable strands around the connecting members and thereby to achieve an immediate tension and length compensation between the cable strands.
  • the connecting members are designed as deflection members, around which a cord is guided around each. It can be provided that the cable strands are slidably supported on the respective deflecting member so that they can move relative to the deflecting member to compensate for an unequal tensile load of the two cable strands.
  • the deflecting members are designed as freely rotatable deflection rollers.
  • the deflecting rollers have a plurality of deflecting disks, with each individual cable being guided around a separate deflecting disk. This allows a particularly simple tension and length compensation between the individual cables of the two cable strands.
  • the deflecting pulleys of a deflection roller are rotatably supported relative to each other.
  • the deflection pulleys can rotate independently, so that in a rope length compensation only the affected individual rope is moved, while the other individual ropes of the rope strand experience no relative movement.
  • the deflecting members are held on a common carrier, which is arranged on the car or on the counterweight.
  • the deflecting members are each held on a separate carrier, which is arranged on the car or on the counterweight.
  • the carriers can, for example, each form a bearing block, on which a deflection member in the form of a deflection roller is freely rotatably mounted.
  • the deflecting members are held by means of a spring element on the car or on the counterweight.
  • the spring element not only allows the compensation of different cable lengths and cable tensions, but secures also a very low-vibration storage of the car or the counterweight.
  • the deflecting members are held by means of a linear adjustment system, for example a piston-cylinder unit, on the car or on the counterweight. By activating the linear adjustment system, the deflecting members can be moved relative to the car or to the counterweight.
  • the mutual distance of the deflecting members is variable.
  • the deflecting members each protrude beyond a side of the car or the counterweight and are held perpendicular to the plane defined by the respective car or counterweight side plane, thereby changing the distance between the deflecting members.
  • the compensating movement of the deflecting members can also take place in the vertical direction.
  • the connecting members each form a pivotally mounted lever arm on which a cable strand is held.
  • a rope length compensation can be achieved in a structurally simple way.
  • the lever arms have a plurality of lever arm elements, on each of which a single cable is held. As a result, a different expansion behavior of the individual ropes of a rope strand can be compensated.
  • the two lever arms are rigidly connected to each other and form a rocker.
  • the rocker may for example be mounted on a stand projecting from the car bearing block.
  • the rocker is pivotally held in the region of a vertical center axis of the car or the counterweight.
  • the rocker is formed symmetrically such that the two lever arms each have the same length.
  • the individual cables of the two cable strands are each coupled to one another via a rocker.
  • the individual cables can each be arranged on a cable tension compensation element at the ends of the rocker.
  • the cable tension compensation elements can be configured, for example, as a one-piece or multi-part spring.
  • the two cable strands have a different number of individual cables.
  • Such a configuration may be particularly advantageous for high shafts. It is advantageous if a rocker is used, which is held in the direction of the cable strand with the larger number of individual cables offset from the vertical center axis of the car or the counterweight pivotally. The rope strand with the larger number of individual ropes is thus held on a shorter lever arm than the rope strand with the smaller number of individual ropes.
  • a rope length compensation and thus a train compensation between the rope strands can be achieved.
  • the pivoting movement of the rocker can be monitored by means of a sensor.
  • a sensor for this purpose, in particular a non-contact sensor, for example a magnetic field sensor, preferably a Hall sensor, can be used or else a conventional incremental encoder which is coupled to the pivot axis of the rocker. It can also be the approach of a lever arm of the Rocker be monitored to the car by the distance between the lever arm and the car is detected by a sensor.
  • a control signal can be output from the sensor when a predetermined pivoting angle of the rocker or a predetermined distance between the lever arm and the car is exceeded.
  • the control signal may be provided to an elevator controller of the elevator system so that the elevator controller may issue a visual or audible warning signal upon the presence of the control signal to indicate to the user that the two cable strands have a very different cable length, for example due to a longer service life of the cable strands.
  • the two connecting members are each configured as pivotally mounted angle lever with a first side arm and an angle, preferably oriented at right angles to this second side arm, wherein the first side arm a cable strand is held and the second side arms connected to each other via a coupling member are.
  • the first side arms may each protrude beyond a side wall of the car or counterweight and may face in opposite directions, with each of the free ends of the first side arm adjacent to a cable strand.
  • the cable strand can be rigidly connected to the respective side arm. It is particularly advantageous, however, if the cable strand is fixed to the first side arm via a cable tension compensation element, in particular a spring element.
  • the second side arms may be vertically aligned with each other via the coupling member.
  • the coupling member may comprise a spring element which is clamped between the second side arms.
  • the coupling member has a linear adjustment system, so that the second side arms, for example, electrically, mechanically, pneumatically or hydraulically coupled to each other.
