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 lift has at least three vertically stacked elevator cars in a shaft. At least three of these cabin zones are allocated to a building zone.
  • the elevator installation has a significantly higher delivery rate.
  • waiting times in transfer floors are further reduced and the emergence of queues largely avoided.
  • 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 therefore in any case more pleasant.
  • the at least three elevator cars of the first elevator have a central and two adjacent elevator cars.
  • 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 central car zone overlaps adjacent car zones.
  • the advantage of the elevator installation with such overlapping cabin zones is that passengers on any floor lying in the overlapping area of the cabin zones can change from a central cabin zone into 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.
  • 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 associated with 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 allows space in the shaft head or Schachtgrube be saved, 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 management 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. However, it is also conceivable that an upper or lower road boundary represents a boundary plane. 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.

  • the drives A1, A2, A3 alternately on opposite shaft walls.
  • 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 of adjacent elevator cars 7b, 7c are positioned above or below the drive A1 of the central elevator car 7a.
  • the distance in the vertical direction between a central drive A1 and an adjacent drive A2, A3 is at least one cabin height.
  • 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 advantage of this arrangement lies in the simple maintenance of the two drives A1, A3. They can be maintained from a common platform.
  • a drive A1, A2, A3 each have a motor M1, M2, M3 and a traction sheave 1a, 1b, 1c.
  • the motor M1, M2, M3 is in operative contact with the traction sheave 1a, 1b, 1c and drives the traction means Z1, Z2, Z3 by means of this traction sheave 1a, 1b, 1c.
  • the traction sheave 1a, 1b, 1c is designed so that it is suitable to receive one or more traction means Z1, Z2, Z3.
  • the traction means Z1, Z2, Z3 are preferably belts, such as V-ribbed belts with unilateral ribs, which engage in one or more drive-disk-side recesses.
  • Belt variants such as smooth belts and single-sided or double-sided toothed belt with corresponding Traction sheaves 1a, 1b, 1c are also usable.
  • various types of ropes such as single ropes, double ropes or multiple ropes can be used.
  • the traction means Z1, Z2, Z3 have strands of steel wire or aramid or Vectran.
  • the at least three elevator cars 7a, 7b, 7c and three counterweights 12a, 12b, 12c are suspended on the traction means Z1, Z2, Z3 as a bottle.
  • the elevator cars 7a, 7b, 7c have at least a first and a second deflection roller 2a, 2b, 2c, 3a, 3b, 3c which are fastened in the lower region of the elevator cars 7a, 7b, 7c.

  • the traction means Z1, Z2, Z3 runs along a first or second shaft wall down to the second deflection roller 3a, 3b, 3c wraps around from outside to inside at an angle of approximately 90 ° and leads to the first deflection roller 2a, 2b, 2c.
  • the traction means Z1, Z2, Z3 wraps around this first deflection roller 2a, 2b, 2c from inside to outside again by approximately 90 ° and is then guided along the elevator cage 7a, 7b, 7c up to the traction sheave 1a, 1b, 1c and wraps around it from inside to outside about 150 °.

  • the counterweights 12a, 12b, 12c are advantageously suspended in their center of gravity S to the traction means Z1, Z2, Z3 between the car guide rails 10.1, 10.2 and first or second shaft walls. Since the elevator cars 7a, 7b, 7c are now centrally suspended, the counterweights 12a, 12b, 12c are also located in a middle region of the first and second shaft walls. Thanks to this central position of the counterweights 12a, 12b, 12c, the clearance between the lateral ends of the counterweights 12a, 12b, 12c and third and fourth shaft walls increases. This gives room for maneuver for the counterweights 12a, 12b, 12c. Thus, e.g.

  • the central car zone K1.2 preferably has two floors less than the number of floors allocated to the building zone G2. Because the middle elevator car can serve all middle floors of the building zone G2 except the two border floors. Because of the vertical stacking of the elevator cars of a group of three 14.2, the middle elevator car can not pass the upper or lower adjacent cars, which occupy at least one perimeter storey of the building zone G2.
  • this includes the two transfer floors U2.1, U2.2.
  • the middle elevator car of the triple group 14.2 for the building zone G2 assumes the function of an escalator 16 by transporting passengers from the upper transfer floor U2.1 to the lower transfer floor U2.2 and vice versa.
  • the two transfer floors U2.1, U2.2 are then the only floors of the building zone G2, which are each served by two elevator cars of the group of three 14.2.
  • the two peripheral floors of the building zone G2 remain the only floors served only by the adjacent lower or upper elevator car of the triple group 14.2. All other floors are served by two elevator cars at maximum extension of the central cabin zone K1.2.
  • the arrangement of the car zones K1.1, K2.1, K3.1, the associated elevator units and the transfer floors U1.1, U1.2 in the building zone G1 essentially corresponds to the arrangement of said elements of the building zone G2.
  • An important additional aspect concerns the transfer floors U1.1, U1.2 of the lower 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, then the incoming passengers arrive as needed thanks to the high capacity of the escalator 16 quickly to the upper transfer floors U1.1 or get when leaving the building quickly from this back to the building lobby.
  • 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 two additional building zones G3, G4 and associated triplets 14.3, 14.4 with the cabin zones K1.3, K2.3, K3.3, K1.4, K2.4, K3.4 and the associated transfer floors U3.1, U3.2, U4.1, U4.2. It can be any number of triads 14 arranged vertically above each other.
  • 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.
  • these car zones K are free to the specific building conditions customizable.
  • the transfer floors U are also freely arrangeable with respect to number and position in a building zone G as a function of car zones K or number of cabins of a multicabine.
  • each elevator car has a conveyor coefficient of 1/9 weighted by the number of floors to be served, which measures the output of the elevator car on a certain floor.
  • the adjacent car zones K2.2 and K3.2 each serve five upper and five lower floors and the central car zone K1.2 eight floors.
  • the result for the area of overlapping cabin zones is a coefficient of promotion of 1/5 plus 1/8 or 13/40 and for the peripheral floors a coefficient of promotion of 1/5.
