Definitions

  • the invention relates to an elevator system with at least two shafts, in which several elevator cars move in one-way traffic.
  • elevator systems with, for example, two shafts in which three or four elevator cars move upwards in the first shaft and downwards in the second shaft.
  • Such elevator systems are designed so that the elevator cars move between a lower end station and an upper end station and can be stopped at these end stations as well as at several intermediate stations.
  • the term elevator car should also be understood to mean load-bearing platforms and similar devices.
  • the mentioned end and intermediate stations can be stations on floors where passengers get on or off, but they can also be stops in which the elevator cars are brought only for logistical purposes.
  • Such elevator systems may have an upper lateral transfer device in the region of the upper end station and a lower lateral transfer device in the region of the lower end station, in order in each case to shift one of the elevator cars from one to the other, also in the one-way system.
  • the system is therefore referred to as a one-way system and the shafts as one-way shafts.
  • Elevator systems comprising a plurality of elevator cars and in particular more elevator cars than shafts are mainly used in relatively tall buildings in which many passengers have to be carried at least at certain times since these elevator systems are more space-saving than a larger number of conventional elevators where each shaft has only one Elevator car serves. With the one-way shafts In a simple and effective way, collisions between elevator cars can be avoided.
  • Elevator systems with several elevator cars and with separate shafts for the ascending and descending movements of the elevator cars are known.
  • US-2003/0217893-A1 describes an elevator system comprising a plurality of elevator cars, a first shaft for the upward movement of the elevator cars and a second shaft for the downward movement of the elevator cars and a third, serving as a parking slot shaft between the first and the second Shaft is arranged.
  • Lateral transfer devices are provided in the area of the upper and lower end stations and in at least one height area located between the end stations in order to move the elevator cars from one shaft to one of the other shafts.
  • This elevator system has cabin-side drive systems.
  • a major disadvantage of this previously known elevator system is the fact that the space requirement is relatively large because of the additional parking shaft, which extends over the entire height of the elevator system. In certain cases, it may also be a disadvantage that cabin-side drive systems are provided.
  • the object of the invention is therefore to provide an improved elevator system of the type mentioned, with which the disadvantages of the prior art are avoided.
  • the new elevator system has only shafts in which elevator cars move, but no parking shafts, so that the space required for one-way movement of the elevator cars is as small as possible.
  • the drive systems are assigned to the shafts, with at least two drive systems per shaft. At least three elevator cars are provided in four drive systems, and there are usually at most as many elevator cars available as drive systems, although additional redundant drive systems may be provided.
  • each elevator car With only two shafts, four elevator cars can be operated, thus the traffic performance is greater than with two conventional elevators, each with a shaft and a total of only two elevator cars.
  • the passenger does not have to orientate for a long time at which shaft door he has to enter the elevator car, as is the case with conventional elevator systems which comprise two separate elevators, because each shaft is assigned a direction.
  • Each elevator car can preferably approach all floors, so operate over the entire lift height.
  • there are four drive systems namely two drive systems per shaft, and a total of four elevator cars. It is assumed that passengers use the elevator system both ascending and descending.
  • the elevator system is used only ascending, while descending a staircase or escalator is to be used.
  • three drive systems can be present in one shaft and only one drive system in the other shaft, so that three elevator cars can simultaneously move passengers upwards in a single shaft at a relatively slow speed, while in the other shaft only one empty elevator car is moved downwards at a comparatively fast speed.
  • the directions of movement of the elevator cars can also be reversed so that, depending on the number of passengers, the shaft can be used with the three drive systems for up or down passengers, in an office building, for example, at the start of work for uphill and at the end of work for downhill.
  • the new elevator system preferably has a central control in order to control the movements of the elevator cars.
  • the movements of the elevator cars are controlled so that the number of elevator cars, which are located simultaneously in a shaft, is limited to the number of this shaft associated drive systems.
  • two drive systems per shaft so are each a maximum of two elevator cars in a slot.
  • the central control can further cause an elevator car located in an end station to be moved into the other shaft via the lateral transfer device at the latest when a subsequent elevator car wishes to reach this end position.
  • the shafts can be at a certain lateral distance from each other. In the area of lateral transfer devices, space can thus be created for one temporary parking station. The space required for this remains small, since the space between the shafts is used only in the area of Lateraltransfer Roaden for the elevator system, while in between other purposes, such as a storage room, for example as a broom, available.
  • the illustrated elevator installation 1 has two elevator shafts 10.1, 10.2 and a total of four elevator cars 12.1, 12.2, 12.3, 12.4.
  • the elevator installation 1 is shown in a state in which two elevator cars are located in each of the elevator shafts 10.1, 10.2.
  • the shaft 10.1 on the left for the upward movement of the elevator cars, and the shaft 10.2 for the downward movement on the right, are arranged on the right.
  • the directions of travel are shown by arrows 11.1 and 11.2.
  • the elevator car 12.4 is located at the bottom in the shaft 10.1, the elevator car 12.1 at a medium height in the shaft 10.1, the elevator car 12.2 is located at the top in the shaft 10.2 and the elevator car 12.3 at a medium height in the shaft 10.2.
  • the elevator cars 12.1, 12.2, 12.3, 12.4 consist essentially of a rigid frame and a cabin body, but it can also be used elevator cars with self-supporting structure.
  • a total of four drive systems are provided, namely the drive systems 14.1, 14.4 in the left shaft 10.1 and the drive systems 14.2, 14.3 in the right shaft 10.2.
  • Each of the drive systems 14.1, 14.2, 14.3, 14.4 comprises an endless drive element 16, preferably in the form of a belt.
  • Each Endlostreibelement 16 is driven up by a drive unit via a drive pulley 18 and runs down to a deflection and tensioning roller 20.
  • each of the drive systems 14.1, 14.2 14.3, 14.4 includes a counterweight 22.
  • the traction sheave bottom and the deflection and Tensioner be arranged above. It could also be provided above or below arranged pulleys and lateral tension rollers.
  • Fig. 1A only the drive systems 14.1 and 14.2 are visible.
  • Fig. 1B only the elevator cars 12.1 and 12.2 are visible.
  • the elevator car 12.1 is coupled to the drive system 14.1 and the elevator car 12.3 to the drive system 14.2.
  • the elevator cars 12.4 and 12.2 are not yet verkuppelt with drive systems. Details regarding this coupling will be described below with reference to Figs. 2A to 2C.
  • FIG. 1A An upper lateral transfer device 24 and a lower lateral transfer device 26, both of which are shown in FIG. 1A only as arrows. Details of the lateral transfer means 24 and 26 will be described below with reference to Figs. 2A to 2C.
  • each shaft is in each case next to each other on one side of the shaft, namely on the shaft side facing away from the other shaft, arranged.
  • the drive systems can also be mounted on the car door opposite side of the shaft, whereby the lateral space requirement is lower, but then only elevator cars can be used, which have a single door or optionally. Two arranged above the corner doors.
  • Figures 2A to 2C show details of the coupling and the lateral transfer means.
  • Fig. 2A shows the elevator system 1 from the side
  • Fig. 2B the top area of the elevator system 1 from above
  • Fig. 2C the bottom area of the elevator system 1 from the side.
  • guide rails 30 are provided, on which the elevator cars 12.1, 12.2 are guided by means of guide bodies 31. Shown are sliding guides formed as sliders guide bodies on the elevator cars, but there are also roller guides in question, which have the advantage of generating lower friction losses. It is not mandatory 4 guides per shaft necessary. It could also be worked with only 2 guide rails per shaft. These would then have to be replaced in the uppermost and lowermost stop, in the area between the shafts, eg by pivoting guides, as shown in FIG. 2B.
  • the guide rails 30 are each on the drive systems 14.1, 14.2 opposite shaft side not available. They are there by pivoting guide systems, in the present embodiment by pivoting guide rollers, replaced. These guide rollers guide an elevator car when the elevator car is not received by the respective lateral transfer device 24. If the corresponding elevator car is effectively accommodated in the lateral transfer device 24, then these pivotable guide systems are pivoted into a release position to allow the horizontal displacement of the elevator car.
  • a so-called backpack guide would also be suitable, that is, a guide device which guides the elevator cars only on one side, for example on the side of the drive systems.
  • a backpack guide would have to be replaced in the area of the lateral transfer devices 24, 26 by a guide system which can be pivoted or moved.
  • Each Endlostreibelement 16 is equipped with a first coupling unit in the form of a coupling plate 32.
  • Each elevator car 12.1, 12.2 has a second clutch unit 34 in order to couple the elevator car with one of the endless drive elements 16 if required.
  • This cabin-side coupling unit is in the present embodiment as horizontally displaceable Bolt assembly formed with a plurality of coupling pins 34.
  • the coupling pins 34 are, when they are in engagement with the coupling plate 32, lockable by means of a locking device, not shown. Instead of coupling bolts and engageable hook arrangements could be provided.
  • the upper lateral transfer device 24 is shown in Figs. 2A and 2B.
  • the upper lateral transfer device 24 is located above the elevator cars when they occupy their uppermost position. Shown in FIGS. 2A and 2B is a state in which the elevator car 12.1 has not yet been decoupled from the drive system 14.1 or endless drive element 16, but is already suspended in the upper transfer arrangement 24.
  • the upper transfer assembly 24 comprises two upper rails 36 and pivoting rollers 38, which can be brought by pivoting in the rails 36 in a working position in which they engage in the rails 36. As soon as these rollers 38 are pivoted into their working position, the elevator car 12.1 can be uncoupled from the drive system 14.1.
  • a lateral drive system 40 in the present exemplary embodiment a chain drive system.
  • a chain 42 or a belt of the lateral drive system 40 must be drivingly connected to the elevator car 12.1 or the rollers 38, to which end an unillustrated additional clutch mechanism is required.
  • the lateral drive system 40 is arranged on the profiled rails 36 and can be driven by means of an electric motor 44.
  • the lower lateral transfer device 26 and the elevator car 12.4 in their lowest position in the shaft 10.1 are shown in Fig. 2C.
  • the lower Lateraltransfer annoyed 26 is analogous to the structure of the upper transfer assembly 24, but it is below each of the elevator car to be transferred when it assumes its lowest position. While the elevator car respectively located in the upper lateral transfer device 24 hangs on the upper profiled rails 36, the elevator car respectively located in the lower lateral transfer device 26 rests on lower profiled rails 46. Shown in Fig. 2C is a state after completion of the lateral displacement of the elevator car 12.4, but with still in the guide rails 46 engaging rollers 38.
  • the elevator system 1 also has an unillustrated speed limit system.
  • This speed limit system is optional.
  • a speed limiter drivable with a friction wheel can be arranged on each elevator car.
  • a safety cable must be coupled to the elevator car if it is not accommodated in one of the lateral transfer devices 24, 26, or the safety cable must be firmly connected to the coupling plate.
  • An electronic speed limiter could also be used.
  • each elevator car that is going upwards serves incoming service calls from the bottom to the top, but in principle only follows operator calls for getting in or out of intermediate stations, which are located above their current height.
  • the elevator car ultimately drives to the upper end station, where all remaining passengers have to get off.
  • the elevator car is decoupled from the drive system and translated by means of Lateraltransfer inevitable for downward travel in the other shaft.
  • the downward journey is analogous to the upward journey in front of him.
  • the elevator car follows the service calls in the downward direction, as far as stops are required in intermediate stations, which are below the current height of the elevator car. In the lower end station, the last passengers leave the elevator car, and this is translated by the lower lateral transfer means for further upward travel into the other shaft.
  • the drive systems make empty runs for counterbalancing without cab. These empty runs can be carried out at high speed because no persons are involved.
  • the whole elevator system has to move clocked. Although it is conceivable to move only the called cabin in a small volume of traffic. Nevertheless, it must be ensured that the readiness is kept, if possible all possible To be able to serve calls as fast as possible.
  • the central control must constantly check the positions of the individual cabins and the GG depending on the traffic volume. The central control would have to be intelligent and optimize between traffic performance, waiting times and energy consumption.
