Definitions

  • the invention relates to an elevator installation with a first elevator cage and at least one second elevator cage, which are preferably arranged in an elevator cage frame of the elevator installation.
  • the invention relates to the field of elevator systems, which are designed as so-called biplane elevator systems.
  • From the WO 2005/014461 A1 is an elevator with two elevator cars known, wherein the two elevator cars are coupled together so that they are movable together in an elevator shaft.
  • a vertical distance between the two elevator cars can be adjusted by moving at least one elevator car relative to the other elevator car. This is done by an adjustment cable.
  • One end of the adjusting cable is fastened to the shaft bottom. At the other end of the adjusting cable hangs a counterweight.
  • the adjusting cable is guided via a drive letter of an adjusting drive, which comprises an elevator machine.
  • This elevator machine is provided in addition to a further elevator machine, wherein the further elevator machine serves to move the entire arrangement with the two elevator cars through the elevator shaft.
  • the from the WO 2005/014461 A1 known elevator system has the disadvantage that to a certain extent two complete arrangements with elevator machines and counterweights and the pulleys required in this regard are required to allow on the one hand the joint movement of the two elevator cars through the elevator shaft and on the other the adjustment mechanism for adjusting the distance between the two elevator cars to realize.
  • the elevator machine which allows the movement of the two elevator cars through the shaft, must be so strong that it alone can move the biplane arrangement with the two elevator cars.
  • the drive machine which is provided for the distance change, must be strong enough to ensure the relative movement of the two elevator cars to each other even in unfavorable loading conditions of the two elevator cars.
  • the relevant components including the traction means or ropes must be designed for a correspondingly high performance. Overall, this results in a high effort, a large amount of space and the associated high costs in the realization.
  • An elevator installation according to the preamble of claim 1 is made JP2003146561 known.
  • the object of the invention is to provide an elevator system, which has an improved structure. Specifically, it is an object of the invention to provide an elevator system in which an adjustment of several elevator cars to each other in an optimized manner is possible and / or at an optionally provided elevator car frame the forces acting on the suspension of the elevator car frame and in the elevator car frame are reduced.
  • the elevator installation has a first elevator car and a second elevator car.
  • further elevator cars can be provided.
  • At least one of the elevator cars, in particular the second elevator car are in this case adjustable relative to the first elevator car with respect to their spacing therebetween.
  • the adjustment mechanism provided for this purpose is described below in a mode of operation which allows an adjustment of the second elevator car relative to the first elevator car.
  • corresponding modifications and additions are conceivable to adjust individually or together and other elevator cars via at least one further adjusting mechanism.
  • a so-called double-decker elevator system can be realized.
  • the driving space provided for the travel of the elevator cars can be arranged in an elevator shaft.
  • the drive machine unit can then also be arranged in the elevator shaft.
  • the prime mover may also be housed in a separate engine room.
  • the adjusting mechanism can then advantageously also be accommodated in the elevator shaft or in the machine room.
  • the drive machine unit is accommodated, for example, in a machine room, while the adjusting mechanism is accommodated in the elevator shaft. In this way, depending on local conditions, in particular the available space, a suitable solution can be realized. This results in a broad scope.
  • the traction means are divided into a first Werschverbund, a second Werschverbund and optionally in at least one further Buchstoffverbund.
  • the traction means may be formed by six cables.
  • the first Werstoffverbund can then include, for example, three of these ropes, while the second Werstoffverbund comprises the other three ropes.
  • both a matching, as well as a different distribution with respect to the number of traction means on the individual Werstoffverbünde is possible. It is also conceivable that at least one of the Werstoffverbünde only from a traction means, in particular a Rope exists.
  • the traction means are guided in a suitable manner over the traction sheave of the drive machine unit.
  • the traction sheave may have a corresponding number of grooves.
  • the term of the traction sheave is not limited to a one-piece traction sheave. If it is expedient, then several discs can be arranged side by side on the axis of the drive unit, over which the traction means run. The term of the traction sheave is thus to be understood in terms of the function of transmitting the output torque of the prime mover unit to the traction means.
  • the traction means may, in addition to the function of transmitting the force or torque of the prime mover unit, also have the function of supporting the elevator cars. Under the method of the elevator cars in the designated driving room is in particular a lifting or lowering to understand. However, an embodiment as an inclined lift is conceivable.
  • the adjustment mechanism cooperates with the second traction mechanism so that a length of a section of the second traction mechanism can be varied between the adjusting mechanism and the second elevator cage.
  • the second elevator car can be moved closer to or further away from the adjusting mechanism. This then changes the distance of the second elevator car from the first elevator car.
  • the adjusting mechanism has a roller arrangement, through which the second Werstoffverbund runs and in this case forms a free loop.
  • the roller assembly has at least one adjustable roller, which preferably cooperates in the region of the free loop with the second Glasstoffverbund.
  • the first Switzerlandstoffverbund and the second Switzerlandstoffverbund can run together on the traction sheave. After the adjustment by the adjusting mechanism is obtained by the rotation of the traction sheave then a steady moving, in particular lifting or lowering, the elevator cars while maintaining the set distance, which have the two elevator cars to each other.
  • the load of the first elevator car is received by the first Switzerlandstoffverbund, while the load of the second elevator car is received by the second Switzerlandstoffverbund.
  • the first Switzerlandstoffverbund can be connected, for example, with the elevator car frame. Since the second Switzerlandstoffverbund is connected to the second elevator car, thus resulting in a reduction of the mechanical load of the elevator car frame.
  • the elevator car frame can be constructed in this respect in terms of its strength with reduced requirements. This makes a cost-effective design possible.
  • the elevator car frame also requires no special modification, so that the design effort is low.
  • At least one guide rail can be provided in the elevator car frame, on which the second elevator car can be moved by the adjusting mechanism relative to the elevator car frame.
  • the relative positioning of the second elevator car with respect to the first elevator car is predetermined when the distance is adjusted via the adjusting mechanism. Apart from the executives, however, no additional load is transmitted to the elevator car frame by the second elevator car.
  • the adjusting mechanism can for example be fixedly mounted on a shaft wall or in a machine room.
  • the adjusting mechanism in particular the roller arrangement of the adjusting mechanism, can also be designed such that in the extreme position in which the two elevator cars are closest, a safety distance is still ensured.
  • the adjusting mechanism has an adjusting drive for adjusting at least one adjustable roller of the roller arrangement.

  • the guide can in this case be provided in an advantageous manner as a linear guide, so that the axis of rotation of the roller along a straight line is movable, which is oriented perpendicular to the axis of the roller.
  • the guide can thus be configured as a horizontal guide, in which the adjustable roller of the roller assembly is guided horizontally.
  • the role of the roller assembly is in this case horizontally and perpendicular to the axis of the roller movable.
