Definitions

  • the present invention relates to cable lifts as described by the preamble of claim 1.
  • Elevator devices in which the elevator car is raised or lowered using ropes are well known.
  • a common procedure is to arrange the necessary elements within an elevator shaft, such as guide rails for the elevator car and pulleys for the ropes, etc.
  • This procedure is not only extremely complex, since a large number of individual elements have to be transported to the respective assembly site and individually arranged there and connected to the remaining elements of the elevator, but at the same time also essentially unsuitable for retrofitting old buildings with elevator systems, because there are no elevator shafts in which the individual elements of the elevator system to be assembled can be arranged.
  • An elevator device is provided in which the essential elements for operating the elevator, including the cable guides, deflection rollers and drives, are combined in modular assembly frames.
  • these assembly units can be connected to form a self-supporting shaft structure, which can be intercepted on a house wall.
  • a self-supporting shaft frame for the elevator can serve as a support element for protective cladding by mounting cladding panels on it.
  • the modular assembly elements are preferably delivered to the assembly site as a pre-assembled complete unit and are only assembled there. Nevertheless, the modular assembly elements allow, in particular, the drive and the rope pulleys to be attached in a wide variety of ways, both within the shaft cross-section delimited by the modular assembly elements and fastened to the modular assembly elements from the outside.
  • these assembly units can be connected to form a self-supporting shaft structure, which can be intercepted on a house wall.
  • a self-supporting shaft frame for the elevator can serve as a support element for a shaft cladding by mounting cladding panels on this.
  • the modular assembly elements are preferably delivered to the assembly site as a pre-assembled complete unit and are only assembled there.

  • FIG. 6 schematically shows a rope pulley 19 which is mounted in a mounting frame 6.
  • a preferably regulated cable brake 20 is arranged on the mounting frame 6, which is in engagement with a brake disk 21 attached to the cable pulley 19.
  • FIG. 7 schematically shows a rope pulley 22, which is rotatably arranged in a mounting frame 6 and preferably projects upwards through an opening 23 therein.
  • Brake wedges 24 are arranged on both sides of the opening 23. In the event of an axial failure of the rope pulley 22, it is pulled upward into contact with the brake wedges 24 by the load of the elevator acting on the ropes 25, so that the elevator is braked in an emergency.
  • FIG. 8 shows a top view of the arrangement according to FIG. 7.
  • the other figures explain advantageous options for arranging the drive.
  • the drive can be fastened outside the "shaft cross-section" defined by the mounting frame, if the requirement of optimal use of space requires it, be fastened within the shaft cross-section defined by the mounting frame.
  • the mounting frame and the guide rails are therefore no longer shown below, because of this Specialist the various mounting options are familiar.
