Definitions

  • the invention relates to an elevator system according to the preamble of independent claim 1 and a use thereof.
  • JP 2003 312960 A discloses an elevator installation according to the preamble of claim 1.
  • a specially designed elevator shaft according to claim 1, which has a local cross-sectional widening in the area where the elevator car and the counter-counterweight meet in the elevator shaft.
  • Fig. 1 shows an elevator system 1.
  • the elevator system 1 has an elevator shaft 10, which in the example shown by a bottom 10.1 side walls 10.2, 10.3 and an (intermediate) ceiling 10.4 is limited.
  • the elevator shaft 10 is at least one elevator car 11 and a counterweight 12, which are arranged along vertical rectilinear guideways 14, 15 movable. Elevator car 11 and counterweight 12 are connected to each other via suspension means, not shown, that when moving the elevator car 11, the counterweight 12 performs an opposite movement, as indicated by the arrows above the elevator cars 11 and below the counterweight 12. In the snapshot shown, the elevator car 11 moves upward and the counterweight 12 down.
  • a single cabin Of course, a multi-deck cabin, for example, a double-deck cabin could be used. In a multi-deck cabin, several cabs are arranged one behind the other and move as an associated cabin transport unit in the elevator shaft.
  • the elevator car 11 and the counterweight 12 move past each other in a proximity area A.
  • the length LA of this approach area A depends on the length of the elevator car LK and the length of the counterweight LG.
  • the approach area A is located at the location of the elevator shaft 10 where elevator car 11 and counterweight 12 meet.
  • the length LK includes the length of the entire cabin transport unit.
  • an extension E of the cross section Q of the elevator shaft 10 is provided in the approach area A in order to reduce the pressure surge which builds up in the approach area A when the elevator car 11 moves past the counterweight 12.
  • Fig. 3A now shows a section CC in the area of the extension E by the in Fig. 1 shown elevator shaft 10th When in the FIGS. 1 and 3A
  • the solution shown is a first possible embodiment of the invention.
  • the extension E sits on the rear shaft wall 10.3.
  • Fig. 3B a further exemplary embodiment of the invention is shown.
  • the extension E is at the rear shaft wall 10.3 and extends over the entire width of this rear shaft wall.
  • This embodiment has the advantage that it is structurally easier to implement than in Fig. 3A shown variant.
  • Fig. 3C Yet another exemplary embodiment of the invention is in Fig. 3C shown.
  • the extension E extends not only along the rear shaft wall 10.3 but also along at least a part of the side walls. It is of course conceivable to extend this extension over the entire depth of the side walls.
  • the effective cross-sectional extension (called QE) is approximately the same size. However, this dimensioning was chosen only to better compare the embodiments with each other. Of course, those in the Figs. 3A to 3C shown examples also applicable to arrangements in which the counterweight is arranged laterally.
  • the arrangement of the cross-sectional widening QE is advantageously chosen according to the arrangement of the counterweight.
  • the extension E may be provided in the form of one or more local extensions on the elevator shaft 10, wherein the effective cross section QW of the elevator shaft 10 in the region of the extension E is greater than in the remaining region of the elevator shaft 10.
  • the extension E which locally increases the effective cross section QW of the elevator shaft 10 can result from an expansion within the elevator shaft 10, as shown in FIG Fig. 1 and 3A
  • the wall thickness d of a wall of the elevator shaft 10 for example, the back wall 10.3 or a plurality of side walls (see, for example, FIG Fig. 3C ) of the elevator shaft 10 in the proximity area A is / are reduced. In this case, outside the elevator shaft 10 no additional space of other building use is withdrawn.
  • the disadvantage of this variant is that the local reduction of the wall thickness d possibly results in a weakening of the building static in the approach area A of the elevator shaft 10.
  • Next 10 disadvantages may arise from a reduced wall thickness of the side walls of the elevator shaft regarding sound, heat or fire insulation of the elevator shaft 10 with respect to the remaining parts of the building.
  • a locally thinner wall can be strengthened statically by structural measures and also the fire regulations can be complied with, for example, by the installation of suitable insulation.
  • Another variant for the local extension of the effective cross section QW of the elevator shaft 10 is the extension of the elevator shaft 10 in the approach area A.
  • the wall thickness of the elevator shaft 10 in the proximity area A is not reduced, but it is backpack-like at a (or several sides) of the elevator shaft 10 an extension E provided.
  • Disadvantage of this variant, however, is that additional space of other building use is withdrawn.
  • extension E considered in cross-section should have an extension which approximately corresponds to the cross-section QG of the counterweight 12 in order to avoid the possibility of the air displaced by the counterweight 12, when the elevator car 11 on the Counterweight 12 moved past. It is therefore necessary to provide a cross-sectional widening which is significantly smaller than the cross-section QA of the elevator car 11. This result is interesting and has not been considered so far. If the elevator shaft 10 had to be locally expanded by the cross-section QA of the elevator car 11, this would lead to large and quite complicated structural measures, and the implementation would not make economic sense.
  • the extension E should have a length LE, viewed in the vertical direction of the elevator shaft 10, which is greater than the length LA of the approaching area A. Since the first contact of the dynamic pressure in front of the counterweight 12 and the dynamic pressure in front of the elevator car 11 is already established Passing the car 11 and the counterweight 12 occurs, in the design of the length LE of the extension E is preferably based on the following formula: 1 . 2 ⁇ L ⁇ A ⁇ L ⁇ e ⁇ 1 . 5 ⁇ L ⁇ A ,
  • a small length extension LE requires little space, a large linear expansion LE favors the ride comfort.
  • a length LE which includes a 25% addition to the length LA, ie L ⁇ e ⁇ 1 . 25 ⁇ L ⁇ A ,
  • the length LE can be adapted to the arrangement of building false ceilings, so that the length LE extends over a number of floors, for example over two floors. This is easy to implement in the building.
  • the cross-section Q of the elevator shaft 10 should preferably expand slowly in the extension region E to the effective cross-section QW.
  • a sudden extension of the effective cross section QW by an edge can lead to additional pressure surges or disturbances. It should therefore be ensured that the extension E viewed in cross-section has a gentle cross-sectional enlargement from the normal shaft cross-section Q to the expanded cross-section Q + QE in the region of the extension E.
  • this transition is easy to recognize. Ideal is an angle W of the transition of less than 10 degrees, wherein an angle W of less than 7 ° proves to be particularly advantageous. (please refer Fig. 4 ).
  • the extension of the cross section QE should be as close as possible to the location of the cross section Q of the elevator shaft 10, at which the dynamic pressure areas of the elevator car 11 and the counterweight 12 meet.
  • the avoidance behavior of the air masses can additionally be favorably influenced by an aerodynamic fairing 13 of the elevator car 11 and / or the counterweight 12.
  • the aerodynamic fairing of the counterweight 12 as in FIG Figure 4 shown, be designed in such a way that the air masses are pushed away from the elevator car 10, in the cross-sectional widening QE.
  • An aerodynamic fairing of the counterweight 12 also has the advantage that the counterweight 12 generates less air resistance when driving through the elevator shaft 10. Due to the shape of the aerodynamic fairing 13 fewer disturbances occur.
  • the extension E is located in the vertical direction of the elevator shaft 10 approximately in the center of the area of the elevator shaft 10 accessible by the elevator car 11. In this area, the elevator car 10 and the counterweight 12 come together ,
  • the invention has proven particularly useful in elevator systems designed as high-speed elevator systems for transporting at speeds of at least 4 m / sec, but an application of this invention also makes sense at lower speeds, if the remaining space is used for the purpose of reducing the space enclosed by the elevator installation Shaft cross-section QV is reduced.
