Definitions

  • the invention relates to an elevator installation with a maintenance area, the upper limit of which is designed to be liftable according to the subject matter of the claims.
  • a maintenance technician usually moves to the roof of the cabin and carries out the maintenance work on the drive unit or further components from there. For this maintenance can be carried out safely is to provide a minimal shelter between the roof of the cabin and the shaft end. This prevents possible crushing accidents in the event of a malfunction or incorrect manipulation of the elevator installation.
  • the space provided for maintenance must be sufficiently large enough for the service technician to easily and quickly access the drive unit or other components to be serviced. The latter applies both to the design of the upper shaft area of a machine room-less elevator system as well as for the design of a separate engine room.
  • such a machine room which is arranged above the shaft space, be provided in high-performance elevator systems in high-rise buildings.
  • the object is achieved by an elevator system with a cab, a drive unit for
  • Procedure of the cabin and a maintenance area in the upper area of the elevator system solved.
  • the maintenance area is delimited against the top with a roof structure which is designed to be raised.
  • Maintenance area here is to be understood as the area in which a service technician resides in order to service components, such as the drive unit.
  • the roof structure covers the maintenance area and closes it against the top.
  • the roof structure replaces a solid concrete or masonry shaft end used in a conventional elevator installation. During normal operation of the elevator system, this roof structure is in a lowered position on a part of the building structure, which encloses the maintenance room.
  • the roof structure is raised. This creates a temporarily enlarged maintenance area. This has the advantage that the maintenance area during normal operation of the elevator system, in which there are no people on the roof of the cabin, can be kept small.
  • the roof structure preferably has a base area which substantially corresponds to the base area of the maintenance area.
  • the footprint of the maintenance area is limited by the lateral shaft walls or side walls of an engine room.
  • the advantage here is the optimal accessibility of all components throughout the maintenance area.
  • the elevator installation comprises a lifting mechanism for lifting the roof structure.
  • the lifting mechanism is connected to a drive.
  • the drive converts electrical, pneumatic or hydraulic drive energy by means of the lifting mechanism into a vertical lifting movement.
  • the roof structure can be lifted quickly and effortlessly. This has an advantageous effect on the maintenance work of the service technician.
  • the components to be serviced are quickly accessible and the maintenance technician can concentrate fully on the essential work steps of the maintenance.
  • the drive of the lifting mechanism of a control unit of the elevator system controllable.
  • a particular advantage of this configuration lies in the automatic raising of the roof structure when the elevator installation is put into a maintenance mode.
  • the maintenance technician preferably sets the elevator installation into maintenance mode via a command input at a command input interface to the control unit.
  • the control unit sends a control command to the drive of the lifting mechanism to raise the roof structure to the maintenance position.
  • the elevator system can be brought back into the normal operating mode via a command input at the command input interface.
  • the control unit preferably sends a control command to the drive of the lifting mechanism to lower the roof structure to the rest position again.
  • the command input interface is preferably arranged outside the maintenance area, for example at a floor door, so that the roof structure is already raised before entering the maintenance area.
  • the lifting mechanism can be prestressed with a spring arrangement against gravity.
  • the spring arrangement thus enables a particularly power-saving operation of the lifting mechanism.
  • the drive of the lifting mechanism can be made smaller.
  • the lifting mechanism is easily manually operated in this embodiment, with a drive can also be omitted.
  • the manual operation of the lifting mechanism in the maintenance area or in an area above the roof structure is made. The latter operating position is preferably on the roof of the building.
  • a side wall is arranged laterally on the underside of the roof structure, which expands downwards.
  • the vertical extent of the side wall corresponds at least to the lifting height of the roof structure.
  • the side wall prevents dirt, water or other unwanted objects from entering the maintenance area or machine room or shaft area after lifting the roof structure.
  • the sidewall is made of tent fabric, tarpaulin fabric, plastic film, sheet metal or other suitable materials that are sufficiently dense and stable to protect the maintenance area from environmental influences. and at the same time not unnecessarily increase the weight of the ceiling structure.
  • the elevator system is designed without a machine room.
  • the cabin and the drive unit are installed in a shaft space, the drive unit preferably in an upper area of the shaft space. Accordingly, the maintenance area is arranged in the upper region of the shaft space.
  • the roof structure closes the shaft space from above.
  • the roof structure is in lowered position largely at the same height as the roof of the building. This results in a particularly advantageous appearance of the roof of the building in the operating mode of the elevator system. Permanent projecting shaft end structures of the shaft space on the roof are thus avoidable.
  • the cabin comprises a roof hatch, via which access to the maintenance area can be released.
  • a first safety switch is connected to the roof hatch in such a way that, when the roof hatch is opened, the first safety switch opens and the elevator system stops. This ensures that a maintenance technician when entering the maintenance area between the car roof and the shaft end or the roof structure is not trapped by a faulty manipulation between the cabin and the shaft end.
  • Another aspect relates to a second safety switch which is connected to the lifting mechanism.
  • the second safety switch is configured so that when raising the roof structure of the first safety switch is reset and the elevator system can be brought into a maintenance mode.
  • the advantage of the second safety switch is that the elevator installation can only be brought into a maintenance mode if the maintenance area is temporarily increased by the lifting of the roof structure. This ensures that the service technician can only carry out manipulations on the elevator installation if the planned safety-related and ergonomic measure is effective for protecting the health of the maintenance technician.
  • the elevator installation is with a machine room fitted.
  • the drive unit is installed in the machine room.
  • the cabin is installed in the shaft as before.
  • the machine room is arranged above the shaft space.
  • the maintenance area is arranged in the engine room.
  • the roof structure closes the engine room from above.
  • the roof structure is preferably approximately at the same height as the roof of the building, thus allowing a favorable appearance of the roof of the building.
  • the FIGS. 1 and 2 show a first machine room-less design variant of the elevator system 10.
  • the elevator system 10 in this case has a cabin 11 which is movable in a shaft space 3 along guide rails 23.

  • These are, for example, electric motors, spindle drives and pneumatic or hydraulic drives.
  • the lifting mechanism 6 is on the one hand indirectly or directly attached to the building structure, namely on the roof 20 or on the shaft walls 21, and on the other hand connected to the roof structure 2.
  • the lifting mechanism 6 is prestressed with a spring arrangement against gravity.
  • the spring arrangement is connected to the building structure and via a lever with at least one arm of the scissors mechanism, that the spring arrangement emits a stored elastic energy to the lifting mechanism 6 during a lifting movement.
  • the spring arrangement absorbs the potential energy emitted by the roof structure 2 and the lifting mechanism 6. This allows the drive of the lifting mechanism 6 smaller dimensions.
  • the lifting mechanism 6 could conveniently be manually raised or lowered in this spring-loaded configuration.
  • the drive can be omitted here if necessary.
