Definitions

  • the present invention refers to elevator arrangements exhibiting at least one cabin for a lift shaft and at least one drive unit, wherein the at least one cabin is coupled with the drive unit by means of at least one traction means interacting with the drive unit, wherein the at least one cabin is guided by means of at least two cabin guide rails preferably arranged on opposite sides of the cabin, wherein the elevator arrangement exhibits guide rails for at least one counterweight, wherein the elevator arrangement exhibits a bedplate assembly providing support for the at least one drive unit.
  • the present invention also refers to a bedplate assembly for such elevator arrangements, wherein the bedplate assembly is processed by providing at least some structural constituents of the bedplate assembly in a favourable configuration, preferably made of sheet material.
  • the present invention refers to use of sheet material for providing at least some of the structural constituent of such a bedplate assembly providing support via the guide rails.
  • the present invention refers to elevator arrangements and bedplate assemblies according to the respective present independent claim.
  • Elevator arrangements exhibiting at least one cabin for a lift shaft and at least one drive unit usually comprise at least one cabin guide rail for guiding the at least one cabin and further comprise at least one counterweight guide rail for guiding at least one counterweight.
  • Such elevator arrangements comprise two cabin guide rails and two counterweight guide rails, wherein the cabin guide rails are arranged vis-à-vis on opposite sides of the lift shaft, and the counterweight guide rails are arranged on the same side of the lift shaft and on the same lift shaft side one of the cabin guide rails being arranged.
  • a/the object of the present invention is to provide for favourable supporting techniques also allowing for favourable arrangement of the at least one drive unit within the lift shaft and for effective mounting and robust design while remaining slim in construction.
  • an elevator arrangement exhibiting at least one cabin for a lift shaft and at least one drive unit, wherein the at least one cabin is coupled with the drive unit by means of at least one traction means interacting with the drive unit, wherein the at least one cabin is guided by means of at least two cabin guide rails preferably arranged on opposite sides of the cabin, wherein the elevator arrangement exhibits guide rails for at least one counterweight, wherein the elevator arrangement exhibits a bedplate assembly which is attachable/attached to at least one of the cabin guide rails and to at least one of the counterweight guide rails, wherein the bedplate assembly provides a mounting plate for fixing and supporting the drive unit via the guide rails, especially exclusively by means of the bedplate assembly and irrespective of any fixation to a wall of the lift shaft.
  • the drive unit is supported by the bedplate assembly and the guide rails, and the guide rails can be fixed directly to/at the wall(s) of the lift shaft.
  • This configuration also allows for slim design and easy mounting; in particular, a fixation interface to/at the lift shaft wall(s) has to be defined only with respect to the configuration of the guide rails, but not with respect to the drive unit's support (bedplate assembly); this also favours easy realization of design adaptations of the bedplate assembly (e.g. in view of different distances between the guide rails).
  • the bedplate assembly further provides for at least one installation point for mounting at least one electrical component at the bedplate assembly and irrespective of any wall of the lift shaft.
  • the present invention also provides for favourable decoupling of electrical components from the lift shaft walls, which also allows for pre-assembly and for standardized definition of the position/arrangement of these electrical components especially also with respect to the drive unit.
  • the drive unit is mounted within a top area of the lift shaft.
  • the drive unit is mounted/supported by means of the bedplate assembly on two counterweight guide rails and on one cabin guide rail, especially exclusively on/via these guide rails.
  • the inventive concept of supporting the drive unit allows for a design/construction which is independent of a/the specific wall construction of the lift shaft; thereby, installation time can be reduced, also.
  • a/the inverter can be mounted also on the bedplate assembly (instead of fixing the inverter on the wall), e.g., the inverter can be fixed to a protrusion or bracket or the like, e.g. in an arrangement hanging down from the height level of the bedplate assembly.
  • a/the stop button can be mounted also on the bedplate assembly (instead of fixing the stop button on the wall), e.g., the stop button is mounted such that it is reachable for service and maintenance work on the drive unit.
  • the drive unit is configured for being mounted/arranged in the top area (head) of the lift shaft, which arrangement allows for quite thin/slim guide rails and less supporting structure (less structural reinforcement).
  • the bedplate assembly also allows for favourable adjustment of the drive unit's position and/or alignment on the bedplate assembly resp. on the respective mounting plate.
  • the bedplate assembly may further comprise levelling screws (e.g. four levelling screws) to adjust the drive shaft's alignment, e.g. in conjunction with gauge plates (calibrated spacer plates) provided between a foot of the drive unit and the mounting plate. Any gap resp. distance/height deviation can be filled/compensated by means of such gauge plates.
  • the bedplate assembly also allows for favourable (mechanical) isolation of the drive unit in view of potential vibrations transmitted to the bedplate assembly resp. on the respective mounting plate.
  • the bedplate assembly may further comprise at least one damping isolation unit (especially in a configuration comprising first and second isolator parts, especially nylon and/or rubber elements), wherein the respective damping isolation unit is advantageously arranged and implemented such that when compressing forces are exerted on the damping isolation unit, at least one screw (or any such pretensioning means) ensures steadiness and adequate pretension.
  • bushes are used/implemented to effect such damping characteristics, wherein two different isolator parts in each damping isolation unit may provide for even more advantageous damping isolation characteristics.
  • the at least one electrical component comprises at least one of a stop button, an inverter, a control unit.
  • the bedplate assembly also provides for functionality for arranging or accommodating at least one of these electrical components, especially irrespective of any additional fixation to a lift shaft wall.
  • the bedplate assembly is configured for arranging two electrical components in predefined positions with respect to each other, namely both a/the stop button and an/the inverter, wherein the installation point for the stop button preferably is arranged within an area limited by the guide rails, and wherein the installation point for the inverter preferably is arranged within a section out of an/the area limited by the guide rails.
  • the bedplate assembly comprises at least one supporting section defining the installation point for a/the stop button, wherein the bedplate assembly comprises a bedplate protrusion, preferably extending in the direction (y) of main extension of the bedplate assembly, defining the installation point for a/the inverter, preferably at the same height level of the mounting plate.
  • the bedplate protrusion allows for favourably arranging/supporting the inverter next to the drive unit and such that no additional space is needed; preferably, the inverter can be mounted in hanging arrangement at the installation point(s) provided by the bedplate protrusion.
  • the bedplate protrusion extends horizontally, especially in (y)-direction as shown in the figures.
  • a/the supporting section for defining the installation point for arranging a/the stop button is provided by a/the respective side plate of the bedplate assembly, especially integrally in one piece. This also reduces complexity of the bedplate assembly.
  • the bedplate assembly is attached to only one of the cabin guide rails and to two counterweight guide rails, especially by supporting the mounting plate and the drive unit on/at these three guide rails. This allows for slim design of the bedplate assembly, especially for a bedplate assembly being reduced to extend only on one side of the cabin resp. of the lift shaft.
  • the bedplate assembly provides for three fixation interfaces to three guide rails, namely a first fixation interface to a first counterweight guide rail, a second fixation interface to a second counterweight guide rail, and a third fixation interface to a/the cabin guide rail.
  • This configuration also favours transmission of forces and torques via a quite great/extended area or surface section, wherein (indirect) load transmission to a lift shaft wall can optionally be realized also at different/several lift shaft walls, i.e., in different spatial planes.
  • the first and second fixation interfaces are arranged in vertical fixation planes.
  • the third fixation interface is arranged in a horizontal fixation plane.
  • each fixation interface may comprise screws and/or rivets or the like, especially such that the bedplate assembly can be mounted based on form-fitting and/or force-fitting attachment techniques (but not based on welding or any such adhesive or material-bonding technique).
  • the bedplate assembly is made/constituted of sheet material, at least substantially. This also allows for a slim and cost-effective design which can easily be adapted for different lift shaft designs or for different guide rail designs or different guide rail arrangements.
  • the bedplate assembly comprises a top cover unit and side plates each fixed to at least one of the guide rails, wherein the mounting plate covers the top cover unit, wherein at least the mounting plate of the top cover unit and the side plates are made of sheet material.
  • the counterweight guide rails are arranged on a/the side of the cabin of at least one of the cabin guide rails, wherein the bedplate assembly extends (only) on that side of the cabin resp. of the lift shaft. This also allows for a slim design and for favourable mounting of the bedplate assembly (only/exclusively on one side of the lift shaft).
  • the bedplate assembly is configured for providing support for the drive unit by force transmission exclusively into/via the guide rails, thereby providing for indirect support and fixation on/at the respective lift shaft wall by means of the guide rails (via the guide rails).
  • This kind of decoupling from any (direct) fixation to a lift shaft wall also provides for considerable improvements as to mounting and handling requirements (especially in an area at the head of a/the lift shaft).
  • the bedplate assembly is configured for being arranged such that a drive zone of the drive unit (resp. the traction means) is arranged at least approximately in the middle of a distance between the counterweight guide rails.
  • a drive zone of the drive unit resp. the traction means

  • the bedplate assembly is configured for arranging and supporting the drive unit such that the drive zone (resp. traction means interacting with the drive zone) is arranged on a/the side of the bedplate assembly on which the bedplate assembly is fixed to the (respective) cabin guide rail.
  • This configuration also allows for spatially limiting the bedplate assembly's area to one side of the cabin resp. lift shaft.
  • a/the top cover unit of the bedplate assembly exhibits a U-shaped cross section. This also provides for high structural resistance and resistibility.
  • the U-shaped profile is arranged such that the U-shape faces upwards, in order to provide for a cavity (which is open to the top) optionally accommodation further structural sections e.g. for structural reinforcement.
  • the top cover unit and the mounting plate provide for a rectangular cross section provided by sheet material sections attached to each other (fastened together) in a form-fitting and/or force-fitting manner, especially by sheet material sections made of same material and preferably having same thickness, especially by maximum three or four different configurations/forms of sheet material sections (especially maximum three or four different blanket parts or laser-cut parts). This also provides for high structural resistance and resistibility.
  • the bedplate assembly exhibits a rectangular base area geometry, wherein the bedplate assembly is connected to the cabin guide rail by means of a cabin guide rail supporting section (resp. supporting unit or profile) optionally also adjusting a lateral offset between the counterweight guide rails and the cabin guide rail, wherein the mounting plate is configured for arranging the drive unit such that a/the drive unit's drive zone is arranged in lateral distance with respect to the cabin guide rail resp. with respect to the laterally extending section, especially in scalable lateral distance.

  • the mounting plate is configured for arranging the drive unit such that a/the drive unit's drive zone is arranged in lateral distance with respect to the cabin guide rail resp. with respect to the laterally extending section, especially in scalable lateral distance.
  • This also allows for providing a compact design for the main structural parts (especially top cover unit, mounting plate, side plates) of the bedplate assembly (especially depending on the relative arrangement of the guide rails to be coupled with the bedplate assembly), and at the same time, a lateral protrusion for most favourable relative position of the drive unit can be realized e.g. by means of additional supporting sections (especially separate parts) laterally extending from the mounting plate.
  • the bedplate assembly comprises at least one laterally extending section configured for further supporting the drive unit in an arrangement protruding a/the top cover unit (resp. mounting plate) of the bedplate assembly, especially at least approximately centrically with respect to the main direction of elongation/extension of the top cover unit.
  • a/the top cover unit resp. mounting plate
  • This also facilitates definition of favourable relative position of the drive unit while not being limited to the geometry of the mounting plate.
  • the bedplate assembly is configured for supporting the drive unit on the guide rails and irrespective of any additional fixation to/on the lift shaft, especially by exclusively coupling with the guide rails (support exclusively via the guide rails but not directly via the lift shaft wall(s)). This also facilitates the creation of a certain standard as far as load-bearing components are concerned, without having to deal with the special features of the lift shaft wall.
  • a/the mounting plate of the top cover unit provides for an even/plane support surface for arranging at least one gauge plate for aligning the drive unit.
