Definitions

  • the invention relates to a guide arrangement for an elevator.
  • Elevators for transporting people and goods contain elevator cars that can be moved up and down in an elevator shaft.
  • the elevator cars can be moved in the vertical elevator shaft using support means, for example in the form of support cables or support belts, by means of a drive unit.
  • the elevator usually includes at least one counterweight that is moved in the opposite direction in the elevator shaft.
  • guide rails that are attached to the elevator shaft are used as guide arrangements.
  • T-shaped metal profiles have been known and in use for a long time.
  • the T-profile has a rail foot attached to a shaft wall and a rail web.
  • the rail web has two opposing guide surfaces and a front guide surface along which a sliding or roller guide shoe can slide or roll.
  • the guide surfaces of the rail web also serve as attack surfaces for safety devices that can be used to brake elevator cars to stop the car.
  • the safety device can also be a safety brake for catching the car.
  • the guide rail designed as a T-profile has proven itself for many years.
  • guide rails for guiding elevator cars are also known which are characterized by a more complex shape.
  • Such a guide rail is known, for example, from WO 2020/127787 Al.
  • the guide rails consist of individual guide rail pieces which are fixed in the elevator shaft by means of mounting brackets.
  • WO 2022/117496 Al discloses such mounting brackets as an example.
  • the guide rail in the type of WO 2020/127787 contains guide contours for both the elevator car and the counterweight in the same component.
  • the guide contour for the elevator car is designed as a U-shaped guide channel.
  • the elevator car has corresponding guide shoes which are accommodated in the U-shaped or groove-like guide channel of the elevator rail.
  • this guide rail has a guide contour formed by two web-like projections for guiding a counterweight. The two projections are oriented away from each other.
  • sliding guide shoes can be used to guide the counterweight, as shown in WO2022/136119 Al.
  • An elevator can comprise an elevator car, which elevator car can be moved in the vertical direction (travel direction).
  • the elevator can further comprise a counterweight that can be moved in the opposite direction to the elevator car, which counterweight can be moved in the travel direction.
  • the guide arrangement for an elevator for the vertical transport of people or goods is characterized in that the guide arrangement for guiding an elevator car and/or a counterweight has a base rail structure that runs in a travel direction, preferably designed as a hollow profile, and a secondary structure attached to the base rail structure and runs in the travel direction, along which secondary rail structure the elevator car and/or the counterweight can be guided, is widened or otherwise designed differently compared to the base rail structure in order to adapt to different load-bearing devices, in particular to adapt to larger counterweights, and to enlarge the guide arrangement.
  • the base rail structure is formed by a profile that extends along the travel direction.
  • the aforementioned preferred hollow profile therefore extends in the direction of travel.
  • the secondary rail structure is also formed by a profile extending along the direction of travel. The enlargement refers to the profile cross-section of the
  • the base rail structure can in turn be a guide rail for a virtual elevator.
  • This virtual elevator can be replaced as required by another elevator, for example an elevator with a higher rated load. Since the new or different elevator usually requires larger or heavier counterweights due to an increase in the rated load, the guide rail specified by the base rail structure may no longer be sufficient to guide the counterweight.
  • the secondary rail structure provides optimal guidance of the larger or heavier counterweight.
  • the guide arrangement enables efficient retrofitting or conversion of the elevator.
  • the secondary rail structure can be used to optimize the guide properties of the guide arrangement and the mechanical load capacity.
  • the secondary rail structure can be designed in such a way that the counterweight can be equipped with safety brakes.
  • An elevator system can only have one counterweight per elevator car.
  • such elevator systems only have one drive, for example a traction sheave drive, which drives the support means and thus moves the elevator car and the counterweight in opposite directions.
  • the elevator car can be moved up and down in the elevator shaft, guided vertically between two guide arrangements as linear guides.
  • the counterweight can also be guided on two guide rails.
  • the elevator system can also have two counterweights per elevator car.
  • the guide arrangement can be designed in such a way that it serves as a linear guide for both the elevator car and a counterweight.
  • the base rail structure can thus form a support for the secondary rail structure.
  • a guide rail in the form of a hollow profile can be used as the base rail structure.
  • This guide rail can be manufactured as a one-piece rolling profile, for example. Further details on the design of such special guide rails and on guiding the car and the counterweights with common guide rails can be found in WO 2020/127787 Al.
  • the two-part and modular design of the guide arrangement increases variability and has the advantage that the guide arrangement can be easily adapted to different load handling devices as required.
  • the secondary rail structure can preferably be designed as an open profile part. Such a secondary rail structure can be easily attached to the base rail structure. Detachable fastening means such as screw connections can preferably be used for attachment.
  • closed profile parts could also be conceivable as a secondary structure, for example in order to obtain a particularly rigid secondary rail structure.
  • the aforementioned profile parts refer to the cross section of the guide arrangement. Guide rails are usually made up of several rail elements or sections arranged in a row, and accordingly the secondary rail structure would also usually consist of several sections or profile elements.
  • the secondary rail structure can preferably be formed by a hat profile or by a hat-shaped profile part.
  • the hat profile has the advantage that the guide contour of the secondary rail structure is spaced from the base rail structure and thus a reliable and effective guidance of the counterweight or possibly even another load-bearing device (elevator car) can be ensured.
  • the secondary structure for example the hat profile, can have a fastening section and leg sections adjoining the fastening section at an obtuse angle, wherein guide sections are provided at the outer ends of the leg sections for forming the guide contours for the load-bearing means and in particular for the counterweight.
  • the wall thickness of the profile for the secondary rail structure is preferably greater than the wall thickness of the profile for the base rail structure, wherein the wall of the profile for the secondary rail structure can particularly preferably be at least 30% thicker than the wall of the profile for the base rail structure.
  • the base rail structure and/or the secondary rail structure can each be rolled steel profiles. Such structures are easy and relatively inexpensive to manufacture. To ensure sufficiently high rigidity, it can be advantageous if the guide sections are created by U-shaped ends bent from sheet metal.
  • the secondary rail structure can be attached to the base rail structure using screw connections. Holes already present in the base rail structure can be used to attach the secondary rail structure, so that no holes need to be drilled on site.
  • the base rail structure may have a plurality of holes distributed at equal intervals along the direction of travel for optionally fastening the secondary rail structure.
  • the direction of travel corresponds to a vertical direction when the guide arrangement is fully installed in the elevator shaft.
  • the invention could then relate to an elevator comprising the guide arrangement described above.
  • a further aspect of the invention is characterized in that, in order to create a guide arrangement for an elevator for the vertical transport of people or goods, a base rail structure, preferably designed as a hollow profile, is first provided, which base rail structure forms a guide arrangement for a first elevator, and that a secondary rail structure is attached to the base rail structure, which is suitable for guiding an alternative second elevator adapted to the elevator, for example with a different counterweight.
  • a hollow profile is a closed profile.
  • the figure shows a cross-sectional view of a guide arrangement according to the invention for an elevator for the vertical transport of people or goods.
  • the guide arrangement designated as a whole by 1, essentially consists of a base rail structure 2 and a secondary rail structure 3 attached to the base rail structure.
  • the base rail structure 2 is known per se and corresponds to the guide rail shown in WO 2020/127787 Al. Thanks to the secondary rail structure 3 described in detail below, a guide arrangement for an elevator is created which allows further applications and in particular enables the elevator to be retrofitted or converted.
  • the base rail structure 2 and the secondary rail structure 3 are profiles that run in the direction of travel.
  • the secondary rail structure 3 thus forms a guide rail attached to the former guide rail 2.
  • Elevators are used for vertical transport in multi-story buildings.
  • the building has an elevator shaft in which an elevator car can be moved up and down to individual floors.
  • the vertical elevator shaft is limited at its lower end by a shaft floor.
  • the elevator shaft has a shaft door opening for each floor in the form of a wall opening.
  • the shaft door opening provides access from the floor into the elevator car.
  • the elevator car is moved by means of support means to which the elevator car is attached; the support means can be one or more support cables or support belts.
  • the elevator car can, for example, be self-supporting or arranged in a support structure, such as a support frame.
  • the elevator car can, in simplified terms, have a cuboid-shaped car body and comprises a car floor, car walls and a ceiling.
  • the elevator car also usually has a car door (not shown) that closes off the interior of the elevator car and faces the shaft wall on the door side.
  • Guide rails are arranged in the elevator shaft to guide the elevator car.
  • One such guide rail is the base rail structure 2 mentioned at the beginning and shown in the figure.
  • the base rail structure 2 could be used to guide an elevator (not shown here).
  • This elevator referred to below for simplicity as the "first elevator" can be, for example, an elevator of the type shown and described in WO2022/136119 A1.
  • This first elevator is designed for a specific nominal load.
  • the counterweights must be adjusted for larger elevator cars or for elevators with a higher nominal load. Heavy elevator cars require counterweights that are adjusted accordingly in weight. This may make it necessary for the original guide of the counterweight to no longer meet the higher demands on the guide of the counterweight. Thanks to a Various advantages can be achieved by using a secondary rail structure 3 attached to the base rail structure 2.
  • a counterweight (not shown) for another or second elevator can be guided along the secondary rail structure 3. This heavier second counterweight requires a modified guide compared to the guide of the first counterweight.
  • the base rail structure 2 is obviously a hollow profile and can be manufactured as a one-piece roller profile.
  • the base rail structure 2 has a U-shaped guide channel 12.
  • a guide shoe for guiding the elevator car can be arranged in this guide channel 12.
  • This guide shoe can be a roller guide shoe with which the elevator car can be guided safely and reliably.
  • the base rail structure 2 also has a mounting area 13, via which the base rail structure 2 is connected to a mounting bracket (not shown) for mounting the base rail structure 2 in the elevator shaft.
  • 10 and 11 designate the guide sections of the base rail structure 2, with which guide sections 10, 11 the counterweight of the first elevator would interact for its guidance.
  • the two guide sections 10, 11 are now, however, without function, since other guide sections are provided for guiding the counterweight of the second elevator, which replaces the first elevator.
  • These guide sections are assigned to the secondary rail structure 3 and are designated 8 and 9 in the figure.
  • the secondary rail structure 3 is wider than the base rail structure 2 to accommodate the larger counterweight and to enlarge the guide arrangement.
  • the clear distance between the guide sections 8, 9 is designated L2. This distance L2 is significantly larger than the distance LI between the old guide sections 10, 11.
  • the secondary rail structure 3 is designed as an open profile part, whereby in the present case the secondary rail structure 3 is formed by a hat profile.
  • the hat profile has a central fastening section 5 and leg sections 6, 7 adjoining the fastening section 5 at an obtuse angle, whereby the aforementioned guide sections 8, 9 are provided at the outer ends of the leg sections 6, 7.
  • the secondary rail structure 3 can be a rolled steel profile just like the base rail structure 2.
  • the guide sections 8, 9 are created by ends bent in a U-shape from sheet metal.
  • the wall thickness of the profile for the secondary rail structure 3 is obviously greater than the wall thickness of the profile for the base rail structure 2. In the present embodiment, the wall of the profile for the secondary rail structure 3 is approximately 50% thicker than the wall of the profile for the base rail structure 2.
  • the secondary rail structure 3 lies flat against a flat side wall 14 of the base rail structure 2, which connects the sections 8, 9 to one another, and is fastened to the base rail structure 2 by means of screw connections 4.
