Definitions

  • the invention relates to an elevator installation in a building with at least one transfer floor. This invention is defined in the preamble of the independent claim.
  • Modern elevator concepts for buildings with 30 or more floors have transfer floors, which are served by a lift system.
  • Such an elevator installation comprises a group of at least two elevators.
  • a first elevator directly services the transfer floors from an entrance lobby, i.e. passengers are roughly distributed from the entrance lobby by a high performance lift to the various transfer floors.
  • a second elevator performs a fine distribution of the passengers from the transfer floors to their destination floors.
  • An elevator usually has an elevator car that can be moved vertically in a shaft and accommodates passengers in order to transport them to a desired floor of a building. To perform this task, the elevator usually has at least the following elevator components: a drive with a motor and a traction sheave, pulleys, traction means, a counterweight, as well as a pair of guide rails for guiding an elevator car and a counterweight.
  • the engine generates the power required for the transport of the passengers present in the elevator car.
  • an electric motor performs this function.
  • This drives directly or indirectly to a traction sheave, which in Frictional contact with a traction means is.
  • the traction means may be a belt or a rope. It serves for the suspension and the promotion of the elevator car and the counterweight, which are both suspended so that their gravitational forces act in opposite directions along the traction means. Accordingly, the resulting gravity, which must be overcome by the drive significantly reduced.
  • a larger drive torque can be transmitted from the traction sheave to the traction means by the larger Aufliegekraft the traction means on the traction sheave.
  • the traction means is guided by deflection rollers.
  • EP 1 526 103 shows an elevator system with at least two elevators in a building, which is divided into zones.
  • a zone comprises a defined number of floors served by a lift.
  • Each elevator is assigned a zone.
  • a transfer floor is provided.
  • At least one of the elevators has two elevator cars that can be moved vertically one above the other on two car guide rails independently of each other. The arrangement of two feeder or transfer booths should help to avoid unnecessary waiting times in the transfer floors.
  • Out EP 1 489 033 is an elevator with at least two elevator cars located one above the other in the same shaft known.
  • Each elevator car has its own drive and its own counterweight.
  • the drives are arranged close to first and second shaft walls and also the counterweights are each suspended below the associated drive to drive or tethers close to first or second shaft walls.
  • the axes of the traction sheaves of the drives are perpendicular to the first and second shaft walls.
  • the two independently movable lift cabins ensure a high flow rate.
  • the positioning of the drives in the shaft near the first or second walls eliminates the need for a separate machine room and allows a space-saving compact arrangement of the drive elements in the shaft head.
  • the object of the present invention is to further increase the delivery rate of an elevator installation for a given shaft cross-section in a building with zoning and at least one transfer floor.
  • the elevator installation according to the invention is located in a building with at least two elevators, the building being divided into building zones and each elevator having at least one elevator cage.
  • Each elevator car can be moved independently via its own drive in an assigned car zone.
  • each cabin zone has at least one transfer deck.
  • a first elevator has at least three elevator cars arranged vertically one above the other in a shaft which have a middle and two adjacent elevator cars, wherein the middle elevator car can be moved independently in a central car zone and the two adjacent elevator cars can be moved independently in two adjacent car zones.
  • the middle cabin zone and an adjacent cabin zone serve at least one common floor. In addition, at least one of these car zones is allocated to two building zones.
  • the elevator installation has a significantly higher delivery rate.
  • waiting times in transfer floors are further reduced and the emergence of queues largely avoided.
  • the elevator system has a greater flexibility in the assignment of trips. Because the change from one building zone to the next is possible in a classic elevator model only via the transfer floors. Here areas of adjacent building zones can be reached without detour via a transfer floor.
  • Another advantage of the elevator installation with such overlapping cabin zones is that passengers on any floor located in the overlapping area of the cabin zones can change from a central cabin zone to an adjacent cabin zone. This allows a more flexible guidance of the passengers.
  • floors are served in the overlapping area of the cabin zones of two elevator cars and thus the delivery capacity of the elevator system is increased.
  • this at least one elevator car of a second elevator is a multicab with at least two vertically stacked cabins. These two cabins are assigned to the same car zone because they are physically connected and thus can only be moved together.
  • the advantage of the elevator installation with double cabin is the doubling of the available cabin volume of an elevator car. Thus, one trip can carry up to twice as many passengers.
  • the multi-cab serves at least two superimposed transfer floors.
  • the advantage of the elevator system is that, when the transfer floors are doubled, the waiting times on the respective transfer floors can be further reduced.
  • the transfer floors have a transfer or a waiting room for the transfer. With a double number of such Umsteigeschreib the changeover is largely conflict-free and if there should be waiting times despite the increased capacity, the passengers have twice the volume waiting room available. A stay in the transfer floors, or transfer or waiting rooms is thus in any case more pleasant.
  • the at least three cabin zones can be allocated to at least two adjacent building zones.
  • the central car zone is assigned to a building zone and the two adjacent car zones are each assigned to the same building zone and to an adjacent upper or lower building zone.
  • the advantage of the elevator system lies in the flexible passenger guidance.
  • the at least three drives associated with the elevator cars can be driven over by the elevator cars.
  • the elevator system has the advantage that the drives can be arranged space-saving and flexible in the shaft without being in conflict with the elevator cars.
  • the at least three drives (A1) assigned to the elevator cars are positioned on a first shaft wall or second shaft wall opposite.
  • the advantage of the elevator system lies in the position of the drives between elevator cars and first and second shaft walls. This space can be saved in the shaft head or pit, where usually the drives are arranged.
  • the drive of the middle elevator car is positioned on the first shaft wall and the two drives of the adjacent elevator cars are positioned on the opposite second shaft wall.
  • the advantage of the elevator system is the flexible and easy positioning of any number of drives and the associated elevator cars in the same shaft.
  • the number of installable drives is limited by the space available in the shaft head.
  • a conflict-free guidance of the tension elements in such a conventional Arrangement of the drives in the shaft head narrow limits.
  • the shaft is defined by six boundary planes space in which one or more elevator cars are moved along a roadway. Usually, four shaft walls, a ceiling and a floor form these six boundary planes. This definition of the shaft can be extended to the effect that a plurality of lanes are also arranged horizontally next to one another in a shaft, along which one or more elevator cars can each be moved.
  • the Fig. 1 shows an elevator with at least three elevator cars 7a, 7b, 7c each have their own drive A1, A2, A3 and are movable independently of each other in the vertical direction.
  • a middle elevator car 7a is arranged between two adjacent elevator cars 7b, 7c, which are located below respectively above the middle elevator car 7a.

  • additional drives other elevator cars are arranged according to the alternating sequence of the drives according to alternately on the first and second shaft walls.
  • the drives A1, A2, A3 are in Fig. 1 positioned at three different shaft heights, the drives A2, A3 adjacent elevator cars 7b, 7c above or below of the drive A1 of the middle elevator car 7a are positioned.

  • the drive A1 of the middle elevator car 7a on a first shaft wall and the drive A3 of the adjacent upper elevator car 7c on the opposite second shaft wall can be arranged at the same shaft height.

  • the upper transfer floor U2.1 is operated accordingly from the upper cabin of the double-decker cabin and the middle and the upper adjacent elevator car of the group of three 14.2.
  • the passengers whose destination floor is located in the central car zone K1.2 always two elevator cars of the group of three 14.2 for the onward journey are available.
  • the adjacent car zones K2.2, K3.2 preferably each contain half of the floors of a building zone G2.
  • the upper cabin zone K3.2 is bounded by the end of the building zone G2.
  • the lower cabin zone K2.2 extends beyond the lower end of the building zone G2 into the building zone G1 and is bounded below by the central cabin zone K1.1 of the building zone G1 or by the associated drive.
  • the middle car zone K1.2 has at least two floors, which correspond to the transfer floors. Preferably, however, the central cabin zone K1.2 extends over as many floors as possible of the building zone G2. Towards the top, the central cabin zone K1.2 is delimited by the elevator car of the upper adjacent cabin zone K3.2. Because the elevator car of the middle cabin zone K1.2 can not pass the upper adjacent elevator car because of the vertical stacking of the elevator cars of a group of three 14.2. The lower boundary of the central cabin zone K1.2 results from the position of the drive, which is assigned to the next but one underlying elevator car. This drive is assigned to the upper cabin zone K3.1 of the lower triple group 14.1.
  • the middle elevator car of the triple group 14.2 takes over the function of an escalator 16 for the building zone G2 by transporting passengers from the upper transfer floor U2.1 to the lower transfer floor U2.2 and vice versa.
  • the lower group of three 14.1 and the associated cabin zones K1.1, K2.1, K3.1 are arranged point-symmetrically with respect to the upper triple group 14.2, wherein the point of symmetry in the center of the shaft 15.1 at a shaft height, that of the boundary line between the building zones G1, G2 corresponds, lies.
  • the transfer floors U1.1, U1.2 are located in a central area of the building zone G1.
  • the middle car zone K1.1 serves both transfer floors U1.1, U1.2 as well as further floors of the building area G1.
  • Said cabin zone K1.1 is bounded above by its associated drive and below by the lower adjacent elevator car.
  • the upper adjacent car zone K3.1 is arranged analogously to the lower car zone K2.2 of the upper building zone G2 across building zones.
  • the car zone K3.1 extends from its associated drive down to the drive of the next-to-last underlying elevator car, which operates floors in the car zone K2.1.
  • This lower adjacent cabin zone K2.1 borders above as said to the upper adjacent car zone K3.1 and below to the lower end of the building zone G1.
  • the two transfer floors U1.1, U1.2 of the lower building zone G1 are connected by an escalator 16.
  • the escalators are often used on building lobbies.
  • the building lobbies are floors in which the passengers enter and leave the building and are therefore frequented by numerous passengers. If, for example, the lower transfer floor U1.2 is now a building lobby, the incoming passengers, if necessary, thanks to the high delivery rate of the escalator 16, quickly reach the upper transfer floors U1.1 or, when leaving the building, quickly return to the building lobby , Depending on the type and location of the building, the building lobby may in principle be located on any floor of the building.
  • the building lobby is usually operated at least by the high-performance lift of the second shaft 15.2.
  • Fig. 6 shows a building with an elevator system that according to the example Figure 4 is configured.
  • the building has two additional building zones G3, G4 with two associated triple groups 14.3, 14.4.
  • These two triplets 14.3, 14.4 have six elevator cars, which can be moved in six assigned car zones K1.3, K2.3, K3.3, K1.4, K2.4, K3.4.
  • each of the two additional building zones G3, G4 are each assigned two transfer floors U3.1, U3.2, U4.1, U4.2.
  • any number of triple groups 14 in a shaft 15.1 can be arranged vertically above one another.
  • Fig. 7 describes an elevator installation in a building with three building zones G1, G2, G3 and two shafts 15.1, 15.2.
  • a first shaft 15.1 five elevator units with corresponding elevator cars 17.1-5 are arranged one above the other, which are independently movable in five car zones K1.1, K1 / 2, K1.2, K2 / 3, K3.1.
  • the three building zones G1, G2, G3 each have two transfer floors U1.1, U1.2, U2.1, U2.2, U3.1, U3.2, each located in a central area of the associated building zones G1, G2, G3 are located.
  • the lowermost elevator car 17.1, the next-highest elevator car 17.3 and the uppermost elevator car 17.5 each define three associated car zones K1.1, K1.2, K1.3, which substantially correspond to the three associated building zones G1, G2, G3. Between these three elevator cars 17.1, 17.3, 17.5 there are two more elevator cars 17.2, 17.4. These two elevator cars 17.2, 17.4 can be moved in two associated cabin zones K1 / 2, K2 / 3. These two car zones K1 / 2, K2 / 3 are cross-building zones arranged. In the lowermost building zone G1, an escalator transports 16 passengers between the two transfer floors U1.1, U1.2.
  • Fig. 8 shows an elevator system with a building zoning and cabin zoning as in the example of Fig. 7 ,
  • the building has four additional building zones G4, G5, G6, G7 with associated transfer floors U4.1, U4.2, U5.1, U5.2, U6.1, U6.2, U7.1, U7.2 and four car zones K1.4, K1.5, K1.6, K1.7 with corresponding elevator cars 17.7, 17.9, 17.11, 17.13, which serve exclusively floors of associated building zones G4, G5, G6, G7.
  • the invention is not limited only to the embodiments shown. With knowledge of the invention it is obvious for the expert to optimize different parameters for concrete building forms. Instead of a double-decker cabin, it is also possible for a plurality of individual single cabins or multi-cabins, which have more than two interconnected cabins, to be moved in a second shaft 15.2.
  • the number of floors allocated to a building zone G is also freely selectable.
  • the building zones G need not have an equal number of floors, but may vary from building zone to building zone. It also does not always have to be assigned only triads 14 a building zone G. Thus, groups of four, five or six, etc. can be assigned to the building zones G.
  • the cabin zones for example, need not be symmetrical within a group of three.
  • each elevator car moved in the building zone G3 has an associated car zone, which comprises eight floors. Since each floor of the building zone G3 is served by two elevator cars, the result is a continuous coefficient of 2/8 or 1/4. The delivery rate is thus clearly above the values of a comparable elevator installation according to the prior art
  • the conveyor coefficient is calculated for floors of a central building zone G4 after similar considerations as before.
  • Elevator car has an associated car zone, which comprises 12 floors.
  • each floor of the building zone G4 is served by two elevator cars. This results in a conveying coefficient of 2/12 for each floor of the building zone G4.
  • the peripheral floors can be operated much more frequently in this example than in an elevator system according to the prior art.
