Definitions

  • the invention relates to an elevator system for transporting persons / Goods, a method for operating this elevator installation and a method for Modernization of an elevator system according to the definition of the generic terms of the independent claims.
  • US5419414 shows an elevator installation with several superimposed in a shaft arranged cabins.
  • the cabins are moved independently.
  • each Cabin has a drive and a counterweight.
  • the cabins are over ropes connected as a conveyor with counterweights. So all cabins are the same Floors of the building can serve above and below those of the Cabins served floors provided alternate spaces.
  • first Cabins move into these alternate spaces and more cabins can take to the place be moved in the shaft of the first cabins.
  • the drives are above the Shaft mounted. This elevator system achieved by increasing the number of Cabins in the shaft increase the flow rate.
  • a disadvantage of the teaching according to US5419414 is that the assembly of several Drives in a machine room above the shaft is expensive. Such a Engine room is often difficult to access. For example. need the drives for the Transportation will be disassembled into the engine room to allow it through corridors and doors fit which corridors and doors are on the way to the engine room. Also is disadvantageous that the presence of a machine room above the shaft as well as the provision of alternative spaces in the shaft the potentially usable Building space keeps low. In particular, floors that are at height the alternative rooms are not accessible from the cabins. From these Disadvantages follows that the reinstallation and modernization of such Elevator system caused high costs.
  • the object of the invention is to provide an elevator system that is simple and is inexpensive to install, which provides a high flow rate and with the an existing elevator system is easy and inexpensive to modernize.
  • These Lift system should be equipped with existing and proven methods of elevator construction be compatible.
  • the invention solves these problems with an elevator system, in which vertical Traversing not one, but at least two superimposed Cabins are moved.
  • the cabins are powered by one drive per cabin move along at least one cabin guide rail.
  • the drives are over Conveyor connected to the cabins. According to the invention, the drives are close arranged on various first walls in the shaft.
  • the drives are thus arranged in the shaft, for example in the shaft head. To this Way the engine room falls away, making the building space is used optimally and at the same time, by the use of at least two cabins in one and the same shaft is a significant increase in capacity.
  • a Mounting multiple drives in the pit head is much easier too accomplish, as outside the shaft in the engine room. So can the Components of the drives are transported through the shaft in the shaft head.
  • a counterweight per cabin is provided.
  • the drives are largely arranged above the counterweights in the shaft.
  • the drives are at largely the same height in the shaft arranged.
  • each drive is a cabin above the Counterweight of this cabin located near the first walls in the shaft.
  • at least one counterweight guide rail per Counterweight provided.
  • the drives on ends of the Guide rails for cabin and counterweight supported.
  • an electrical system for the elevator is at least partially supported on the guide rails for cabin or counterweight.
  • the drives and / or the electrical system are directly or indirectly via horizontal beams worn by the guide rails for cabin or counterweight or are the redesignstofffixin directly or indirectly via horizontal support to the Guide rails for cabin or counterweight attached.
  • 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.
  • Advantageously Guide rails, counterweights and drives close to two first walls attached, while the floor doors are attached to two second walls.
  • B spw. are Guide rails, counterweights and drives close to two first walls in the Shaft attached while access to the elevator system via landing doors takes place, which floor doors are attached to two second walls.
  • At least one alternative space for at least one cabin provided, which alternative space in the shaft head and / or in the shaft bottom is arranged.
  • an existing Engine room converted to an alternative space for at least one cabin.

  • the various walls 111, 112, 113, 114 are delimited by edges, which edges are, for example, rectangular and extend through the length of the shaft 11 .
  • the shaft 11 may also have other cross-sectional shapes such as a hexagon with six different walls, it may also have a circular cross-section with several different wall areas.
  • a circular shaft consists of four wall areas of 90 ° each or six wall areas of 60 °, etc.

  • a first conveying means 5 connects the lower car 1 to an upper counterweight 2 and a second conveying means 5 ' connects the upper car 1' to a lower counterweight 2 '.
  • the counterweights 2, 2 ' are moved next to the cabins 1, 1' . For example. the cabins are moved 1,1 ' in the middle of the shaft and the counterweights 2, 2' are moved at the shaft edge close to the first walls 111, 112 .
  • the conveyor 5, 5 ' may have any shape, it may also be made of any materials.
  • the conveyor 5, 5 ' is a round rope, double rope or a belt.
  • each of the counterweights 2, 2 ' uses at least one counterweight guide rail 6, 6 ', 7, 7'.
