Definitions

  • the invention relates to a method for modernizing an elevator door system of an elevator installation and a modernization kit with components required for carrying out the method. It relates to the problem of modernizing elevator door systems of older elevator systems so that they have achievable, advantageous operating characteristics with new technologies.
  • the elevator door system includes a car door which when closed closes a door opening area of a car and releases this door opening area when opened, a door operator which can move the car door, and a hoistway door which when closed closes a door opening area of a floor-level shaft access and this door opening area in an opened state releases.
  • the car door opening and the landing door opening are in coincidence when the car is in a stop on a corresponding floor. So that the movement of the car door can be transferred to the landing door present on each floor, a car door / landing door coupling is usually present on the car door, which is actuated on one floor when the elevator car stops and connects the car door to the corresponding landing door. To do this, the car door / landing door coupling engages on one floor in a shaft door lock provided on the shaft door and couples the car door with the shaft door.
  • a large number of older elevator door systems are in use worldwide, in which a door operator with a crank mechanism often moves at least one car door via a drive linkage.
  • a crank arm which may also be present in the form of a crank disc, driven by a drive motor via a countershaft so that the crank arm for generating an opening movement or a closing movement of the at least one car door performs a pivoting movement of preferably about 180 °.
  • a crank rod is connected at its one end to the end of the crank arm and at its other end to a door drive lever which is pivotally mounted on a frame of the door operator and coupled at its end to the car door.
  • a second car door may be driven by the same crank arm via a second crank rod and a second door drive lever symmetrically to the first car door.
  • the doors are now opened synchronously and closed again later.
  • the two Mit supportivekufen be folded on the car door by the action of the release lever on the car door / landing door coupling, whereby the play-free connection between the car door and the landing door is canceled.
  • the car door / shaft door coupling Due to the arrangement and the space requirement of the crank mechanism, the car door / shaft door coupling is below the door drive and it is attached to a substantial part in the areas of the car door opening on the car door.
  • the shaft door-side shaft door lock is naturally fastened to the shaft door in the area of the shaft door opening.
  • the door openings of the car door and shaft door are defined by a passage height HT and a passage width BT of the car or shaft entrance.
  • Door drives of the type described are increasingly due to age repair and maintenance.
  • the mechanically relatively complex door drive with drive motor, engine brake, crank gear with countershaft and multiple lever joints already requires considerable effort for the review, maintenance and readjustment due to its construction.
  • This effort increases strongly with increasing age of the door drive parts, as more and more parts due to Altersverschleiss need to be repaired. Many of these parts are no longer used in new door systems and therefore have to be reconstructed in elaborate individual work.
  • the crank gear with countershaft and drive linkage also forms a strong source of noise, it is poorly adaptable to changing building use and it sets the design of a door driving curve mechanical limits. These limits and disadvantages are hardly accepted in today's elevator systems.
  • Out JP2000-289955 discloses a method for replacing shaft doors, wherein a car door is provided with a second car door / shaft door coupling, whereby the car door can operate both old and new shaft doors during a period of shaft door conversion.
  • This method does not provide a solution for replacing a car door while retaining major parts of the existing landing door.
  • Out EP1621510 a modular elevator door system is known, wherein the car door and landing door are built with identical basic modules. The disadvantage is that no efficient way is shown how such a system can be used for modernization without shut down a lift system for a long time.
  • the invention has for its object to propose measures that make it possible to eliminate the above disadvantages in existing elevator systems with the least possible effort.
  • an existing repair-prone door system in particular a car door drive, can be easily modernized and a downtime of the elevator system for carrying out such a modernization should be kept low.
  • the object is achieved by a method according to the invention for modernizing an elevator door system of an elevator installation as well as a modernization kit with components required for carrying out the method.
  • the modernization kit according to the invention is characterized in that the modernization kit consists of two groups of components, a first group comprising at least one new door drive and at least one new car door / shaft door coupling, and a second group comprises new manhole locks and intermediate or door panels at least corresponding to a number of floors or hoistway doors of the elevator system, the components of the first group being parts for rebuilding the car door system, and the components of the second group being for rebuilding the hoistway doors.
  • the invention is therefore based on the idea to modernize an old elevator door system with the least possible effort, being maintained primarily existing original shaft doors with the associated existing shaft door frame and shaft door guides.
  • the cabin door can also be left on a case-by-case basis. Only the wear-intensive parts such as the existing car door drive and the car door / shaft door coupling are replaced by a new door drive with new car door / shaft door coupling and the old shaft door shaft lock is replaced by a new shaft door lock tuned to the new car door / landing door coupling.
  • the original cabin door is occasionally replaced by a new cabin door as part of the renovation, or as part of the modernization even an entire cabin body with cabin doors, door drive and cabin door / shaft door coupling is replaced.
  • This alternative is interesting, as it allows essential elevator components which are subject to aging and wear to be renewed in a modernization order, without the need for wall and building renewal.
  • the new shaft door lock is connected by means of wire or Bowden cable to an existing in the existing shaft door emergency release lock.
  • An emergency release serves to open a shaft door from the floor from the outside. This serves, for example, for the liberation of trapped passengers in the event of a defect in the elevator installation or it also serves for service purposes.
  • This emergency release is arranged according to the arrangement of the old shaft door lock usually in the door panel area of the shaft door. By means of a wire or Bowden cable, this existing emergency release can easily be connected to the new shaft door lock. This is inexpensive, requires no intervention in the structure of the building and the handling of the emergency release remains unchanged for the user.
  • the new shaft door lock is connected by means of intermediate plate to the original shaft door.
  • This is advantageous since such an intermediate plate can be prepared in a production plant and provided with necessary connection points, such as threads, stops, etc. This will accelerate a conversion in the building.
  • the new landing door lock is integrated into the original landing door by means of a door support panel by removing original door roller supports and replacing them with the new door support panel, with the new door support panel providing connection points for door guide rollers and the new shaft door lock.
  • counterparts belonging to the shaft door lock are placed by means of an assembly jig in relation to the new shaft door lock.
  • the shaft door lock requires a counterpart, in which the lock, or the locking hook of the lock, engages for the purpose of locking.
  • an electrical contact that monitors for proper interlocking requires a corresponding contact counterpart.
  • These counterparts are attached to the existing, old hoistway door frame.
  • An assembly jig is optimally suited to place such counterparts with respect to a reference location corresponding to the new hoistway door lock. As a result, the conversion in the building can be carried out quickly, safely and cost-effectively.
  • An elevator door system 2 consists of a car door system 4 and a hoistway door system 21.
  • the car door system 4 closes and opens access to an elevator car 3 as needed, and the hoistway door system 21 closes and opens access from a floor E to a hoistway 40 in which the car 3 is arranged movable.
  • Cab door and landing door define a door opening.
  • the door opening or a corresponding area of the door opening is defined by a free passage height HT and a free passage width BT of the car or shaft entrance.
  • this door opening area HTxBT corresponds to the passage which is free to enter the car when the car door and the landing door are opened.
  • Cabin door system 4 and shaft door system 21 are connected to each other such that a common opening or closing is possible when the car door system 4 stops in the area of a landing door system 21.
  • An old cabin door system 4a as in Fig. 1k shown, in the illustrated example consists of two car doors 5 and a door drive 6a.
  • the old car door system 4a is part of the elevator car 3.
  • the illustrated door drive 6a moves the two car doors 5 via a drive linkage by means of a crank gear 9a.
  • a crank arm 13a here in shape a crank pulley 10a is present, is driven by a drive motor 11a via a countershaft 12a so that the crank arm 13a to generate an opening movement or a closing movement of the car doors 5 performs a pivoting movement of about 180 °.
  • a crank rod 14a is connected at its one end to the crank arm 13a, and crankshaft 10a, and at its other end to a door drive lever 15a.
  • the door drive lever 15a is in turn pivotally mounted at one end to a frame 16a of the door drive and coupled at its other end to the car door 5.
  • the second door 5 is mirror-inverted connected to the same effect as the crank arm 13a.
  • this door drive 6a are designed and arranged so that a half turn of the crank arm 13a produces a complete opening or closing movement of the car door 5, wherein the crank mechanism 9a generates an approximately sinusoidal, jerk-free movement of the car door with precisely defined end positions.
