Definitions

  • the invention relates to an elevator system for transporting people or loads, with a car that hangs on at least one support rope running over at least one roller or on which at least one weight compensation rope is attached to compensate for the car and / or payload and that is driven by means of a traction sheave or hydraulically is, in which flexible, multi-core electrical conductors are attached to the elevator car at one end as a power supply to the car for safety devices, lighting, door drive etc. as well as for command and data transmission to the operating and display elements and at the other end it is continued from a fixed point on the shaft wall or shaft ceiling and on a fixed elevator control is connected.
  • the flexible electrical conductors are sheathed, for example, with plastic and form a so-called hanging cable, which, independently of the supporting rope or weight balancing rope, is fastened separately in the car and at the fixed point in the shaft and often has to be additionally guided because it is from the car hanging cable bend in every car height requires a space necessary for the constantly changing deflection.
  • the hanging cable which is usually attached at one end to the underside of the car, runs through the cable arch traveling downwards and very easily causes the cable side attached to the shaft to vibrate. Conversely, experience has shown that the cable side hanging underneath the car oscillates particularly easily when driving upwards.
  • the object of the invention is to eliminate the above-described disadvantages arising from the use of a fixed conductor line or a hanging cable, including those of the unfavorable overall visual impression, in an elevator installation of the type specified above, and - while at the same time improving the previous quality of the feed and / or transmission security - To reduce the effort for energy supply and data transmission between the car and the stationary elevator control.
  • this object is achieved in that in the at least one support rope or weight compensation rope, which is attached with one end of the rope to the car and with the other end of the rope to the shaft ceiling or in the shaft, multi-wire electrical conductors for supplying energy to the car and for Command and data transmission are integrated, the conductor wires of which the cable end attached to the car end can be connected to the corresponding connections of the car and the conductor wires of which the cable end attached to the shaft ceiling or in the shaft can be connected to the corresponding connections of the fixed elevator control.
  • Facade lifts for cleaning the outside of buildings are known in which a carrying cable provided with a multi-core electrical conductor is firmly attached to the nacelle at one end and can be rolled up or rolled off on a driven cable drum with its other end.
  • the electrical conductor or conductors are connected to a manipulable control element / control device in the area of the nacelle.
  • energy and electrical signals from the integrated electrical cables, carbon brushes and one or more slip rings by commutator type must be transferred from the rotating to the fixed component of the cable drum or vice versa.
  • elevator systems have the great advantage that neither a separate hanging cable nor a conductor line or similar separate devices are required for the energy supply and for the command and data transmission to the car, and thus all associated guide and fastening parts including the necessary assembly.
  • the material and assembly costs thus reduced also result in a considerable cost advantage, which also includes the time advantage for faster plant construction.
  • the fact that the maintenance or repair work resulting from the susceptibility of a suspension cable or dragging pantograph is no longer necessary is highly advantageous for the customer or operator of such an elevator system.
  • the advantages described above apply in particular to external elevator systems which are additionally at risk from the effects of weather or other environmental conditions. In elevator systems on external facades or in free-moving lifts in large interiors, the lack of the hanging cable gives an improved overall visual impression.
  • all these ropes contain integrated multi-core electrical conductors and have the same structure and dimensions, so that all ropes are equally loaded and exposed to the same wear.
  • only one electrical conductor can of course also be integrated in a rope according to the invention. If the required transmission capacity is sufficient, it is possible to connect only the electrical conductors integrated in one or a part of the ropes for the energy supply and for command and data transmission at both ends, while one or more ropes integrated with electrical conductors as a replacement line are available and can be connected in the event of transmission errors. Basically, the other ropes do not need to contain any integrated electrical conductors.
  • the electrical conductors are not integrated in the at least one support rope or weight compensation rope, but are arranged as one or more sheathed conductors (cables) next to the weight-loaded rope and routed continuously over the same rollers .
  • This embodiment also solves the problem of the invention, namely the to eliminate disadvantages arising from the use of a hanging cable, since the sheathed conductors running next to the weight-loaded rope are tensioned and guided exactly like this, without oscillating movements or premature conductor breaks occurring.
  • the sheathed electrical conductors are preferably guided next to or between the support cables or weight compensation cables in empty cable grooves in the traction sheave and / or deflection pulleys.
  • a support cable 10 is attached at one end to a clamping device 14 attached to the top of a car 12 and from there is guided over a driven traction sheave 18 mounted on an upper shaft ceiling 16. From the other side of the traction sheave 18 from runs back into the shaft 20 support rope 10 via a roller 22 which is mounted on an axle loaded with a counterweight 24.
  • the support cable 10 electrical conductors are integrated, which protrude or extend behind the cable end points determined by the clamping devices 14 and 26 beyond the respective end of the cable rope ends there or nearby and for the energy supply to the car and for the command and Serve data transmission.
  • the exposed flexible multi-core electrical conductor bundle or cable 28 protruding beyond the supporting sheath or outer region of the support cable 10 is guided to an elevator control 30 arranged on the shaft ceiling 16, where corresponding conductor cores are connected to a power supply, to switches and to command and data transmission devices.
  • the conductor strand integrated into the suspension cable 10 is also extended beyond the end of the suspension rope fixed in the clamping device 14 on the elevator car, the conductor wires of this conductor strand 32 leading to a switch box 34 arranged on the elevator car, where they connect to corresponding terminals for supplying energy for lighting, Door operator, etc. and on Terminals for command and data transmission from and to the operating and display elements in the car are connected.
  • FIG. 2 shows a hydraulically driven car 12, wherein a schematically illustrated hydraulic cylinder 38, supported vertically on the shaft floor or base 36, acts laterally on the car 12 with its piston rod.
  • a hydraulic drive the car 12 can be driven just as well with an electric linear motor with a force application on the car or on the counterweight or with a spindle drive or with other mechanical drive elements.
  • a weight compensation cable 40 is fastened to the car 12 and, like the load cable in FIG. 1, is fixed with a cable end in a clamping device 14 arranged on the top of the car.
  • the weight compensation cable 40 is guided over a deflection roller 42, the axis of which is mounted in support parts 44 projecting downward from the shaft ceiling 16.
  • the area of the weight compensation cable 40 leading downward from the other side of the deflection roller 42 runs similarly to FIG. 1 via a roller 22 which is mounted on an axle loaded with a balance weight 46. That from the other side of the Roll 22 upward weight balancing cable 40 is fastened by means of a clamping device 26 fixed on or above the shaft ceiling 16.
  • the weight compensation cable contains the electrical cable integrated in the cable, which are extended as conductor or cable strands via the clamping devices 14, 26 or the load-bearing cable sheath held there or protrude from it and for energy supply and for command and data transmission are connected between the elevator control 30 and the switch box 34 attached to the car 12.
  • FIG. 3 a car 12 with an indirect hydraulic drive is shown in FIG. 3.
  • This drive comprises a hydraulic cylinder 50 supported vertically on the shaft floor 36 or above it, a supporting part 54 fixed to the piston rod 52 thereof, a deflection roller 56 mounted on the supporting part, and a supporting rope 58 guided over the height-adjustable deflection roller 56, which like the supporting rope in FIG. 1 contains integrated electrical conductors.
  • One end of the supporting cable is fastened in a clamping device 14 arranged on the upper side of the car 12 and the other end of the supporting cable 58 in a clamping device 26 anchored to the bottom of the shaft or above.
  • the electrical conductors of the support cable are as conductor or cable strands over the clamping devices 14, 26 or extended beyond the load-bearing cable sheath held there, the conductor ends projecting from the cable sheath for energy supply and for command and data transmission being connected between the elevator control 30 and the switch box 34 fastened to the car 12.
