Definitions

  • the invention relates to an elevator installation with at least one elevator car carrier which can accommodate two or more elevator cars.
  • the invention relates to the field of elevator systems, which are designed as so-called double-decker elevator systems.
  • a double-decker elevator is known.
  • a first elevator car and a second elevator car are arranged vertically one above the other.
  • a spindle drive is provided, which serves for actuating the two elevator cars. Upon actuation, the two elevator cars are either moved towards or away from each other.
  • the double-decker elevator known from EP 1 074 503 A2 has the disadvantage that the spindle drive has a relatively high degree of friction, resulting in unfavorable efficiency for the adjustment of the two elevator cars. Specifically, this requires a correspondingly large dimensioning of the drive for adjusting the two elevator cars required. Furthermore, an achievable adjustment speed is relatively low. There is also the problem that during operation the spindle is exposed to environmental influences, in particular dusts, which further increases the problems of increased friction. This also requires frequent maintenance and lubrication to allow reliable operation.
  • the object of the invention is to provide an elevator installation in which a distance between the elevator cars arranged on the elevator car carrier can be set quickly and reliably.
  • an elevator system which has at least one elevator cable.
  • a first elevator car which is arranged on the elevator car carrier, a second elevator car, which is arranged on the elevator car carrier, and at least one adjusting device, which for adjusting the first and the second Elevator car relative to the elevator car carrier serves, comprises.
  • the adjusting device has at least one first rack, which is at least indirectly connected to the first elevator car, at least one second rack, which is at least indirectly connected to the second elevator car and at least one gear, which engages in the first and second rack.
  • the first and second racks are arranged with respect to the gear such that rotation of the gear sets the first and second elevator cars in opposite directions.
  • a positive connection is formed in an advantageous manner.
  • This positive connection can absorb both tensile forces and compressive forces, which act on the first and the second elevator car, for example during braking or acceleration of the elevator car carrier.
  • a special catching or braking device which serves to catch or brake the first and the second elevator car with respect to the elevator car carrier, is dispensed with.
  • the adjustment device thus enables not only the adjustment of the first and the second elevator car relative to the elevator car carrier but also a secure attachment of the first and the second elevator car to the elevator car carrier. Thus, a high reliability is guaranteed.
  • the distance between the first and the second elevator car is also very quickly adjustable.
  • the elevator cage carrier can be arranged, for example, in an elevator shaft.
  • an engine unit may be provided in the elevator shaft, which serves for actuating the elevator car carrier.
  • the elevator car carrier can be moved along the intended roadway.
  • the elevator car carrier can be suspended on a traction device.
  • the traction means may in this case be guided in a suitable manner via a traction sheave of the drive machine unit.
  • such a traction means in addition to the function of transmitting the force or torque of the engine unit to the elevator car carrier to operate the elevator car carrier, may also have the function of supporting the elevator car carrier.
  • An actuation of the elevator car carrier is to be understood in particular as a lifting or lowering of the elevator car carrier.
  • the elevator car carrier can be guided by one or more guide rails which are arranged in the elevator shaft.
  • the gear is fixedly connected to the elevator car carrier and can be driven by a drive.
  • the gear is preferably connected in the region of a cross member of the elevator car carrier with the elevator car carrier. The gear thus provides a link between the first and the second rack and the elevator car carrier. Therefore, the first and the second elevator car are at least coupled via the adjusting device to the elevator car carrier.
  • the first rack in the area of the ceiling of the first elevator car is connected to the first elevator car.
  • the second rack in the area of the ceiling of the second elevator car is connected to the second elevator car. Consequently, the length of the respective rack can be kept short.
  • the first and the second rack can also be connected in the area of the floor to the respectively associated elevator car.
  • the mechanism for the conversion to an opposite direction of movement of the first and the second rack and the first and the second elevator car upon rotation of the gear is simply realized.
  • At least one cabin guide rail which is stationarily connected to the elevator car carrier, in order to guide the first and the second elevator car.
  • a movement of the first and the second elevator car is guided relative to the elevator car frame.
  • the adjusting device has a further first rack, a further second rack and a further gear.
  • the other gear is fixedly connected to the elevator car carrier.
  • the further first rack are at least indirectly connected to the first elevator car and the other second rack is at least indirectly connected to the second elevator car.
  • the gear and the further gear are preferably driven by a common drive.
  • a gear is provided between the drive and the gear and the other gear.
  • the gear and the other gear can also connect to the drive via an inclined drive shaft.
  • the control of the drives is less complex, since the requirements for a synchronous rotational movement of the gears can be realized more easily.
  • a further adjusting device which serves for adjusting the first and the second elevator car relative to the elevator car carrier.
  • the further adjusting device is arranged on a side facing away from the adjusting device of the elevator car carrier.
  • two opposing gears of the adjusting device and the further adjustment by means of a common drive shaft operatively connected.
  • at least one transmission couples the drive to the drive shafts.
  • two opposing gears of the adjusting device and the further adjusting device are each driven by a common drive.
  • a synchronous operation of the drives by means of a control unit is ensured.
  • a rack is forcibly guided by means of a counter-pressure roller with respect to the gear.
  • a rack is guided by one or more sliding guides on the elevator car carrier.
  • FIG. 1 shows a lift installation in a schematic representation according to a first embodiment of the invention
  • the elevator car carrier 2 has side members 6, 7, which are connected to one another via cross members 8, 9, 10. On the cross member 10 rollers 11, 12 are arranged, around which a traction means 13 is guided. The traction means 13 also runs around a traction sheave 14 of a drive unit 15.
  • the elevator car carrier 2 According to the current direction of rotation of the drive unit 15 driven traction sheave 14 of the elevator car carrier 2 is moved in a direction 16 upwards or in a direction 17 down through the driving compartment 3. Thus, the elevator car carrier 2 can travel in the driving directions 16, 17 through the driving space 3.
  • a first elevator car 20 and a second elevator car 21 are arranged at the elevator car carrier 2.
  • both the first elevator car 20 and the second elevator car 21 are suspended by means of an adjusting unit 34 relative to the elevator car carrier 2.
  • the adjusting unit 34 comprises at least a first rack 60.1, a second rack 61.1 and a gear 29.
  • the first rack 60.1 engages from outside into the gear 29 and the second rack 61.1 engages from inside the gear 29 a.
  • an operative connection between the gear 29 and the second rack 60.1 and on the other hand an operative connection between the gear 29 and the second rack 61.1 is formed.
  • the first rack 60.1 is connected to the first elevator car 20 and the second rack 61.1 is connected to the second elevator car 21.
  • the first and the second rack 60.1, 61.1 are connected to the respective elevator car 20, 21 in the area of the ceiling 54, 52. This results in stability and weight advantages over a version with longer racks.
  • the first and the second rack 60.1, 61.1 only have a toothing in their upper area 61.1. The toothing is tuned to the lifting height of the first elevator car 20.
  • a drive is provided, which is attached to the elevator car carrier, for example in the region of the upper cross member 10.
  • the drive is used to drive the gear 29.
  • the drive via a drive shaft to the gear 29 is connected.
  • a torque of the drive can be converted by the interaction of the gear 29 with the racks 60.1, 61.1 in an adjusting force to the first and the second elevator car 20, 21 relative to the elevator car carrier 2 to adjust.
  • the first and the second elevator cars 20, 21 are adjustable in opposite adjustment directions 32, 36 or 33, 35, depending on the direction of rotation of the gear 29.
  • the adjusting device 34 thus allows an opposing lifting 35 and lowering 36 of the first elevator car 20 and lifting 32 and lowering 33 of the second elevator car 21 relative to the elevator car carrier 2. In this way, a distance between the elevator cars 20, 21 can be varied within certain limits. Thus, advantageously, a positioning of the two elevator cars 20, 21 with respect to the floors 4, 5 take place.
  • the distance between the first and the second elevator car 20, 21 is set so that it coincides with the distance between two adjacent floors 4, 5.
  • the elevator car frame 2 with the two elevator cars 20, 21 is moved by means of the drive machine unit 15 to the level of the breakpoints of the floors 4, 5.
  • an exit level 40 of the first elevator car 20, which is given by a floor 53 of the first elevator car 20, and an exit level 50 of the second elevator car 21, which is given by a floor 51 of the second elevator car 21, is at least approximately equal to the level of the breakpoint 4 and the level of the holding point 5 in accordance.
  • positioning of the first and the second elevator cars 20, 21 relative to the elevator car carrier 2 can take place even before reaching the stopping points 4, 5.
  • a floor distance may vary within the building, as partial levels are provided for receiving ventilation or air conditioning facilities.
  • Another example is a different floor height.
  • a reception with a greater ceiling height can be provided in a ground floor.
  • the adjusting device 34 has a further toothed wheel 28, which is connected to the elevator car frame 2 on a side of the elevator cars 20, 21 opposite the gear wheel 29.
  • the gear 28 is preferably arranged in the region of the upper cross member 10.
  • a further first rack 60.2 and another second rack 61.2 are provided.
  • the further first rack 60.2 is also connected to the first elevator car 20 and engages from the outside into the further gear 28.
  • the further second rack 61.2 is connected to the second elevator car 21 and engages from the inside into the further gear.
  • the other first and second racks 60.2, 61.2 are interlocked only in an upper region 30.2, 31.2.
