Definitions

  • the invention relates to an elevator, in particular an external elevator.
  • Exterior lifts are used, for example, on construction sites of building construction to transport people and material in the upper floors of the building to be built or renovated.
  • Such external elevators regularly have a guide which is fixed to a wall of the building and extends in the vertical direction.
  • the guide consists of one or two mast towers on which / which a car is movably arranged.
  • the car serves to accommodate the persons to be transported or the goods to be transported.
  • the mast towers thus serve to guide the movement of the car, which may also represent a part of the drive train.
  • at least one of the mast towers is provided with at least one toothed rack which extends in the longitudinal axial direction of the guide and in which a pinion of an electric traction drive engages.
  • the travel drive is thus accommodated in the area of the car and is thus moved along with the car.
  • a structure of such a lift is associated with a considerable effort.
  • the guidance is successively extended by attaching individual guide segments, wherein the guide segments in the car are transported to the upper end of the already constructed guide section and set from the car to this end.
  • a problem with such a construction is the guidance of the cable during construction.
  • the cable must in fact follow the up-and-down movement of the car, this movement taking place by the successive extension of the guidance over increasing distances.
  • the invention was based on the object of specifying an improved in particular with regard to its construction ability elevator.
  • a generic elevator comprising a guide, a ground station, a car guided on the guide, a cable guided along the guide to the car, in particular flat cable, which is guided via a cable trolley with a deflection device following a movement of the car, and a central feed , which serves for the clamping fixation of the cable and can be fixed to the guide, according to the invention further developed in that both at the ground station and on the car a storage device for supporting a portion of the cable (hereinafter cable section) is provided.
  • Such an elevator allows a structure according to a method in which the guide is successively extended by attaching individual guide segments to a total length, wherein the central feed, following the extension of the guide, is fastened at different heights to the guide.
  • the invention provides that a required to increase the center feed extension of the guided between the central feed and the ground station cable section is made up from the storage facility of the ground station and made necessary due to the extension of the extension of the guided over the cable car cable section from the storage facility of the car becomes.
  • a section of the cable can be stored both in the area of the ground station and on the car (which are preferably of essentially the same length) during construction.
  • the center feed can already be fixed at the beginning of the construction at that point of the cable, at which this is to fix the cable during operation.
  • the cable may preferably be provided with a length scale (eg printed). The extension of the cable section between the ground station and the central feeder, which is necessary because of the displacement of the central feed-in, can be achieved by tracing from the Store the cable in the area of the ground station.
  • Dismantling of the elevator according to the invention is possible in a corresponding manner.
  • the increasingly shortened cable section between the center feed and the ground station can be stored in the storage facility of the ground station, while the increasingly shorter required length of the process of the car enabling, guided over the cable car cable section is compensated by a storage in the storage device of the car.
  • An advantageous possibility to store the cable sections in the storage device of the ground station and / or the car may be to stack them in the form of 8ern ("aft") or simple loops one above the other.
  • This can be a space-saving and cable-friendly storage option.
  • Significant advantages of this type of storage on the one hand are the relatively large length of the cable section deposited in the individual layers and, on the other hand, the advantageous handling during stripping during the construction of the elevator.
  • An aft bearing is particularly useful when using a round cable (cable with a round, in particular circular cross section) to avoid the generation of a twist of the cable during stripping.
  • the storage devices may include storage rods around which the corresponding cable portion is laid to form the individual figure-of-eight or loop layers.
  • the storage rods may be provided for storage in "straight" aft or loops.
  • a particularly good utilization of the storage area available in the storage facility can be achieved in that the storage facility of the ground station and / or the car supports the respective cable section in angled aft or loops (at their intersection points).
  • the storage device can have (for example) (at least) three storage rods that are not lying in a straight line.
  • the storage device of the car is arranged on the roof.
  • the area available there can be used advantageously.
  • such an arrangement of the storage device in contrast to a storage on one or more of the side walls of the car, which is also possible in principle, have the advantage that the storage device does not increase the base of the car. Thus, for example, this can not come into collision with a defense of the ground station.
  • the corresponding cable section is mounted in angled aft.
  • the central feed can have fastening means, such as an eyelet, for receiving a lifting element (eg a hook).
  • fastening means such as an eyelet

  • a cable holder arranged on the car or moving along with it can be provided, in which the cable can be fixed.
  • the cable holder can, if the cable is fixed therein, primarily serve as a strain relief for the connection of the cable to the drive arranged on the car.
  • the cable holder can guide the cable so that it runs at a sufficient distance from the car. As a result, contact of the cable with the car during operation can be avoided.
  • cables can be made up of the arranged on the car storage device.
  • this may have a clamping device for fixing the cable.
  • This can in particular be designed such that the clamping action is self-reinforcing in cooperation with the weight of the guided over the cable car cable section.
  • the clamping device in its clamping position is spring-loaded.
  • a pulling device can be provided, in which the cable can be fixed and has the means for moving (the pulling device) along or for fixing to the guide.
  • the pulling device can be used in particular if the central feed at the beginning of the construction is not at the correct, i. final location on the cable has been fixed and therefore the center feed is to be fixed at a different point of the cable during assembly. Then the center feed can be fixed to the guide and the cable pulled up by means of the pulling device, i. be retrieved from the storage facility of the ground station, without the central feed is moved.
