Definitions

  • the invention relates to a method for modernizing an elevator system according to the definition of the preamble of the claim.
  • US5419414 shows an elevator system with several superimposed in a bay cabins.
  • the cabins are moved independently.
  • Each cabin has a drive and a counterweight.
  • the cabins are connected via ropes as a conveyor with counterweights. So that all cabins can serve the same floors of the building, alternative rooms are provided above and below the floors served by the cabins.
  • first cabins can move into these alternative spaces and further cabins can be moved to the place in the shaft of the first cabins.
  • the drives are mounted above the shaft.
  • a disadvantage of the teaching according to US5419414 is that the assembly of multiple drives in a machine room above the shaft is expensive. Such a machine room is often difficult to access. For example. The drives must be disassembled for transport into the engine room so that they pass through aisles and doors, which corridors and doors are on the way to the engine room. It is also disadvantageous that the presence of a machine room above the shaft and the provision of alternative spaces in the shaft keep the potentially usable building space low. In particular, floors that are at the height of the alternative rooms can not be served by the cabins. From these drawbacks follows that the re-installation and modernization of such a lift system causes high costs.
  • WO02 / 030801 discloses an elevator installation with several cabins arranged one above the other in a shaft. The cabins are moved independently. For this purpose, each cabin has a drive placed in the shaft head. In the embodiments shown, two 1: 1 suspended cabs are associated with a single 2: 1 counterweight.
  • the object of the invention is to provide an elevator system that is easy and inexpensive to install, which provides a high capacity and with an existing elevator system is easy and inexpensive to modernize.
  • This elevator system should be compatible with existing and proven elevator manufacturing processes.
  • the invention achieves this object with a method for modernizing an elevator installation, which is characterized in that at least two cabins arranged one above the other in the vertical travel direction are mounted in a shaft, with at least one cabin guide rail for guiding the cars, with one drive per booth which drives are arranged close to various first walls in the shaft, with conveying means for connecting the drives and cabins, with a counterweight per cabin, with at least one counterweight guide rail per counterweight, which counterweights and the counterweight guide rails close to the first walls in the Shaft are arranged, wherein the drives are arranged at substantially the same height in the shaft, and wherein at least one escape space is provided for at least one cabin, which escape space is arranged in the shaft head and / or in the shaft bottom and an existing engine room to at least ei An alternative space for at least one cabin is rebuilt.
  • the drives are thus arranged in the shaft, for example in the shaft head.
  • the engine room falls away, whereby the building space is used optimally and at the same time, by the use of at least two cabins in the same shaft, a significant increase in capacity occurs.
  • An assembly of several drives in the shaft head is much easier to accomplish, than outside the shaft in the engine room.
  • the components of the drives can be transported through the shaft in the shaft head.
  • each drive of a car above the counterweight of that car is located close to the first walls in the manhole.
  • At least one counterweight guide rail per counterweight is provided.
  • the drives are supported on ends of the guide rails for cabin and counterweight.
  • conveyor fixing points are fastened to the guide rails for the car or counterweight.
  • an electrical system for the elevator is at least partially supported on the guide rails for the car or counterweight.
  • the drives and / or the electrical system are supported directly or indirectly via horizontal beams of the guide rails for cabin or counterweight or the constructiveffenfixa are attached directly or indirectly via horizontal support on the guide rails for cabin or counterweight.
  • the guide rails for cabin or counterweight or the horizontal support also form a self-supporting structure for supporting the drives, the cabins, the counterweight and the electrical system as well as for fixing the winning advicefixa.
  • This structure is largely symmetrical and mirrored with respect to a diagonal of the shaft cross-section. Thus, no essential interface to the building is necessary, which simplifies the re-installation and assembly of the elevator system.
  • the access to the cabins is via floor doors, which floor doors are arranged on second walls in the shaft, which second walls are different from the first walls.
  • guide rails, counterweights and drives are mounted close to two first walls, while the floor doors are mounted on two second walls.
  • At least one escape space is provided for at least one cabin, which alternative space is arranged in the shaft head and / or in the shaft floor.
  • an existing engine room is converted into an alternative space for at least one car.
  • a first cabin By providing at least one escape space above or below the served floors of the building, a first cabin can be moved into this escape space.
  • This first cabin occupies now no more space in the shaft area of the served floors and a further cabin can be moved into this place.
  • a further cabin can operate the floor below or above the outside space, in particular in the case of an impact operation leading to an increase in the delivery capacity.
