Definitions

  • the invention relates in the first place to an elevator installation and then also to a method for converting or modernizing an elevator installation.
  • An object of the present invention is to provide a further embodiment of an elevator installation and a method for retrofitting an elevator installation.
  • an elevator system having the features of claim 1.
  • the invention comprises an elevator system with an elevator car - instead of a previously commonly used, simultaneously acting as a power and signal suspension cable suspension cable - a power suspension cable for the supply of electrical energy
  • At least two individual, independent suspension cables namely a current suspension cable and a signal suspension cable, replace the single suspension cable acting simultaneously as a power and signal suspension cable.
  • signal hanging cable independent of the power suspension cable in the present context means a suspension cable for the transmission of signals and / or data that does not form a common cable with the power suspension cable.
  • suspension cables can be multicore cables, for example so-called flat cables.
  • a suspension cable can be mechanically coupled to at least one further suspension cable.
  • at least two flat cables can be coupled together along their entire length at several points, so that several suspension cables form a unit.
  • the advantage of the invention is that such a lift system with a power suspension cable and at least one independent signal hanging cable is easily convertible to an elevator system with wireless transmission of signals and / or data between the elevator control device and the elevator car, wherein after such Conversion the suspension cable arrangement advantageously only the power suspension cable with the required for the supply of electrical energy (power supply) to the elevator car wires. For this purpose, only the disassembly of the at least one, in a future wireless transmission of signals and / or data no longer needed signal suspension cable is required while the power suspension cable is installed.
  • Another advantage of the invention is that the division of the hitherto customary, acting as a power and signal hanging cable suspension cable in a power suspension cable and a signal hanging cable reuse of the need in the course of retrofitting the elevator installation signal become suspension cable in one other lift system allows.
  • the effort for the periodic control and possibly for necessary corrections of the suspension geometry and the rolling behavior of the suspension cable arrangement is reduced after a conversion to wireless transmission of signals and / or data between the elevator control device and the elevator car .
  • the reason for this effort reduction is that only the power suspension cable is to be monitored, which is relatively narrow and flexible and therefore causes fewer problems than a sauadriges wide suspension cable or more parallel to each other suspension cables.
  • a connection unit electrically and / or communicatively connected to the elevator control device is provided for connecting the power suspension cable and the signal suspension cable.
  • a connection unit allows the physical separation of the connection points of the current suspension cable and the signal suspension cable from the elevator control device.
  • a signal suspension cable connected to the connection unit or to the elevator control device is automatically detectable.
  • means for the wireless transmission of signals and / or data between the elevator control device and the elevator car can be activated.
  • transmit / receive units come into consideration.
  • the advantage of such an embodiment is that the elevator system quasi automatically and automatically switches between a wired transmission of signals and / or data by means of the signal suspension cable and a wireless transmission of signals and / or data, depending on whether a connected signal Suspension cable was detected.
  • the signal suspension cable can be removed independently of the current suspension cable at the elevator car and at a respective opposite connection point, that is to say at the elevator control device or at the connection unit, for example.
  • electrical and mechanical contact elements are provided on the elevator car and on the respective opposite connection point, wherein the electrical contact elements, for example plug-in / socket combinations known per se, and the mechanical contact elements are basically also plug-in housings known per se, which form-fit with a plug housing receptacle, in particular form-fitting and lockable, can be combined.
  • the above formulated object is also achieved by means of a method for modernizing an elevator installation of the type described here and below.
  • a signal suspension cable independent of a power suspension cable is disassembled and the signal suspension cable is replaced by wireless transmission of signals and / or data using means for wireless transmission of signals and / or data between the elevator control device and the elevator car.
  • FIG. 1 schematically shows in a very simplified manner an elevator installation 10 in a building (not shown) with an elevator car movable in an elevator car 12 and an elevator control device 14 arranged in the building.
  • the elevator control device 14 is provided in a manner known per se for controlling the elevator installation 10.
  • the elevator car 12 is movable in a manner known per se in the elevator shaft so that different floors 16 of the building can be reached.
  • a drive device 18 for example in the form of an electric motor, is provided in a manner known per se.
  • the drive device 18 drives in a likewise known form a traction sheave or the like, so that by means of one or more guided over the traction sheave carrying cables 20, the respective movement of the elevator car 12, usually a vertical movement, and a movement of a counterweight 22 takes place.
  • FIG. 2 shows this again in a schematically simplified form and with further details.
  • the approach proposed here can be seen, according to which, instead of the hanging cable 24 (FIG. FIG. 1 ) for the joint transmission of energy as well as signals and / or data a first, designated for distinction as a current-hanging cable 26 hanging cable, and a second, designated for distinction as a signal hanging cable 28 hanging cable use.
  • the two suspension cables 26, 28 may, insofar as they otherwise hang freely and in parallel in the elevator shaft, be mechanically coupled to each other along their entire length at some points.
  • connection unit 30 which also functions as a fixed point or as one of several fixed points for the suspension cables 26, 28 (junction box).
  • connection unit 30 has for insertion of the suspension cables 26, 28 each have a corresponding cable gland with or without strain relief, or a socket for attaching a mounted on the cable ends connector housing, so that both an electrical and a mechanical connection of each suspension cable 26, 28 with the Connection unit 30 takes place.
  • FIG. 3 shows the elevator system 10 after a conversion to a wireless transmission of signals and / or data between the elevator control device 14 and the elevator car 12, which transmission is referred to briefly as wireless signal transmission.
  • a first and a second transceiver unit 32, 34 which are referred to below as communication modules 32, 34, function as such means.
  • a first communication module 32 is included as a functional unit of the elevator control device 14 or associated with the elevator control device 14, for example by the communication module 32 is installed in or on the connection unit 30.
  • a second communication module 34 is located in or on the elevator car 12. Both communication modules 32, 34 are in a manner known per se for the wireless transmission and reception of signals and / or data between the two communication modules 32, 34 or other similar communication modules (not shown).
  • connection unit 30 comprises means for detecting whether a signal hanging cable 28 is connected to the connection unit. If it is automatically detected that no signal hanging cable 28 is connected, the communication module 32 is automatically activated, and the elevator cabin side communication module 34 is activated due to a first reception of signals and / or data from the communication module 32. The transmission of signals and / or data between the elevator control device 14 and the elevator car 12 then takes place in the future by means of the communication modules 32, 34 wirelessly. In contrast, when a connected, leading to the elevator car 12 signal cable 28 is detected, the transfer of data between the elevator control device 14 and the elevator car 12 via the signal cable 28th
  • An elevator installation 10 and a method for retrofitting an elevator installation 10 are indicated, wherein instead of a common suspension cable 24 for the supply of electrical energy to the elevator car 12 and the transmission of signals and / or data between the elevator control device 14 and the elevator car 12, a power suspension cable 26 and a signal suspension cable 28 independent of the power suspension cable 26 is installed so that in case of conversion of the elevator installation 10 to wireless signal transmission, the signal suspension cable 28 can be removed without affecting the supply of electrical energy to the elevator car 12, and in place of the wire-bound signal transmission between the elevator control device 14 and the elevator car 12, a wireless signal transmission 32, 34, 28A can occur.
