Definitions

  • the present invention relates to a guideway device with at least three longitudinal sections consisting of two head sections, each with a first and second head longitudinal section and at least one intermediate section, wherein the respective longitudinal section has a support structure comprising side wall units, wherein the guideway device can be produced in a comparatively simple and precise manner thanks to advantageous position referencing. Furthermore, the present invention relates to a method for assembling such a guideway device with reference to reference points, in particular when handling the individual longitudinal sections or longitudinal section modules. Last but not least, the present invention also relates to the use or provision of material recesses laser-cut into side walls or side wall units of a support structure of such a guideway device for defining and providing structurally load-bearing reference points. In particular, the invention relates to a device and a method according to the preamble of the respective independent claim.
  • the greatest possible accuracy with regard to the relative installation position and absolute dimensions of the individual components is desirable, for example also in the area of a transition from the inclined to the straight longitudinal section of the escalator.
  • escalators and similar guideway devices must be assembled taking into account a certain tolerance range of the individual components, in particular in order to be able to deal with unavoidable residual inaccuracies without final assembly becoming impossible due to tolerances that are too tight; However, it is usually not possible to ensure the same small dimensional/positional tolerances for all of these components.
  • the tolerances that can be maintained for the lattice-like support structure are usually larger than the permissible and actually observed tolerances for many or even all other usually smaller and in many cases more precisely manufacturable components or at least for most of the other components (such as guide rails, balustrades, drive systems or the like), there is a need for optimization in order to achieve higher precision of the entire escalator, particularly with regard to the design and relative arrangement and as precise as possible positioning of the structural components of the support structure.
  • Examples include the publications EP 3 426 588 B1 and EP 3 426 589 B1 which each describe a device and a method for producing a passenger transport system based on several joining steps. Furthermore, the EP 3 724 118 B1 which indicate measures intended to facilitate order picking or other measures preparatory to production or the production process, particularly in the case of escalators.
  • the task is to provide a device-related concept and a method with which the dimensional/positional accuracy of escalators or guideway devices in general can be improved. and individual assembly steps can be made easier. It is also the task of designing the corresponding device in such a way that at least some of the assembly aids used to date are no longer necessary or can at least be replaced by slimmer/smaller/less expensive or more flexible/variable assembly aids.
  • a guideway device (in particular escalator device, moving walkway device) is provided with at least three longitudinal sections consisting of two head sections, each with a first and second head longitudinal section (in particular platform section and inclined section) and at least one intermediate section, wherein the respective longitudinal section has a support structure comprising side wall units, wherein at least one structurally loadable reference point is arranged on the side wall units, by means of which the respective longitudinal section or the guideway device assembled from several longitudinal sections can be positioned in a predefinable manner, in particular relative to another longitudinal section or relative to the ground at a predefinable tilt angle or relative to a side stop; wherein by means of the side wall units and the reference points arranged therein, a longitudinal section-specific positioning reference is provided integrally for each longitudinal section, with respect to which further components or assemblies or further longitudinal sections (relative to one another or relative to the longitudinal section) can be positioned in a predefinable manner (relative positioning in particular without absolute spatial position specifications).
  • This also provides a good compromise between
  • the present invention could also be conceived in the following context: Tolerances in the escalator structure (truss or sheet metal), which are higher than the permissible tolerances for most other components such as guide rails, balustrade, drive components, led to the consideration of considering it expedient to create an exact system which helps to compensate for tolerances in the manufactured support structure, in particular with regard to good mechanical coordination and optimal functioning of the escalator, and not least with regard to good manufacturing aesthetics and manufacturing quality. According to the invention, the comparatively precise reference system described here can be created in the manufactured support structure, i.e.
  • the reference system described here which is provided integrally on the side wall units with module-specific reference recesses, can not only be designed to absorb the loads to be controlled (in particular the dead weight of the guideway device), but can also make the use of complex assembly aids unnecessary, e.g. also with regard to a rail embedded in the floor for aligned longitudinal alignment.
  • the side wall units or side walls can also be seen as the main components of the support structure to which many or all other assemblies can be attached.
  • This type of referencing is advantageously carried out during the entire manufacturing process of the guideway device or the individual longitudinal sections/longitudinal section modules, so that tolerances of the support structure are minimized or shifted to less important areas such as the base plate, and the same reference system can also be used during final assembly to position/align the support structure in the assembly line and can also be used to position additional attachments or components on the supporting structure.
  • the reference system referred to here is provided by pairs of integral reference recesses or by at least one integral reference axis formed therefrom per longitudinal section (module), wherein the reference recesses are preferably introduced by fully automated laser cutting in a material-removing manner.
  • the reference recesses are provided in side wall section units which can be used in a scalable manner for each side wall level to form a longitudinal section or module (modularity also at the module-internal level).
  • an intermediate module comprises a side wall structure which repeats every two or three meters and which can be provided, for example, from one-piece flat material by side wall section units which can be arranged next to one another and connected to one another in a particularly materially bonded manner, and in which the reference recesses are introduced when the scalable side wall structure is created.
  • a number of reference recesses can be provided in a side wall level which corresponds to the number of side wall section units used to form the entire side wall of the module, e.g. three side wall section units with reference recesses in at least two longitudinal positions each.
  • the positioning of escalators or moving calender/escalator modules with reference to a reference system that is preferably integrated into the side walls of the supporting structure by means of laser cutting makes it possible to use the same reference or reference position throughout the entire assembly process (in particular, including supporting structure production and final assembly).
  • the respective side wall (of the respective module) itself becomes the reference for the assembly process, which enables a comparatively strong decoupling of any assembly aids that may have to be provided separately (for which such accuracy may not be guaranteed), which means that the assembly process can be carried out in a lean and variable manner and also largely independently of the available equipment or design of an assembly hall, which not least also improves global availability.
  • the method of position referencing described here not only enables the required precision for a module-specific design of the support structures, but also noticeably facilitates modular/modular assembly and final assembly (including assembly of all modules) and provides numerous process-related advantages (same reference system preferably for each production step from the introduction of the reference recesses).
  • the respective module "carries" its own reference system or provides position referencing largely independently of separate assembly/alignment aids.
  • the respective reference recess is designed to absorb at least the dead load of the respective module and optionally also the load of at least the support structure of the entire guideway device.
  • several reference recesses can be combined with one another for better support and load distribution, e.g. two or three reference recesses per module-specific side wall. Last but not least, this also provides the option of optionally supporting the entire guideway device at different support points.
  • Such reference points on the side walls can also be used to "skip" tolerances in the lower and upper truss areas, e.g. by providing the reference points in those sections of the supporting structure in which a very small tolerance can be ensured in terms of manufacturing technology, and by positioning assembly/fastening points e.g. for balustrades or guide rails (other built-in components) in relation to these reference points even if these assembly/fastening points are arranged in areas of the supporting structure that can usually only be manufactured or provided with comparatively large tolerances (dimensional deviations).
  • the reference recesses described here can also be used for the arrangement of adapter plates, in particular in a preparatory phase when positioning two modules face to face, before the form-fitting/non-positive connection/marriage of the modules.
  • the adapter plates can be mounted on the reference recesses of a first module and facilitate flush docking of the adjacent (second) module, in particular by providing corresponding tapered guides (at least one) on the respective adapter plate; the adapter plates are advantageously mounted on the outside of the respective side wall, in particular at least approximately centrally with respect to the total height of the cross-section of the support structure.
  • a corresponding guide bolt can be mounted on the adjacent (second) module, in particular also on at least one reference recess, in particular also in the relative position described here relative to the support structure.
  • Such adapter plates can be provided in a simple and cost-effective manner, in particular from sheet metal.
  • the adapter plates can make it easier to connect the modules both when working with a pit (one of the head modules is tilted with its end section below the working level and reaches deeper than a machine hall floor into a pit and can optionally be supported there) and when working without a pit; when working without a pit, the working level for the entire support structure (i.e.
  • the head module to be tilted downwards is still positioned with its free end above the floor of the machine hall; in this phase, at least the head module is suspended from a crane if necessary, so that the adapter plates can make it easier to align or at least guide the module as it approaches the adjacent module until it touches the edge (or until a gap specified/specified by the adapter plate).
  • the steps outlined here show that the form-fitting/non-positive connection concept for marrying the modules can be implemented in a very flexible and variable manner with high precision and with minimal assembly aids, largely independent of location (i.e. both as a preparatory measure at the manufacturer's site and on a construction site for final assembly at the destination).
  • the respective adapter plate can be provided without any problem regardless of location and can also be designed so inexpensively that even a single use (if not reusable) can be priced in without any problems.
  • defined gap dimensions can also be created with high precision, which can be used advantageously, for example, to weld parts or material sections together with butt welds (e.g. at the kink in the transition area from the platform section to the inclined section in the respective head module).
  • the present invention provides an advantageously high level of accuracy, in particular such that the respective longitudinal section module can be referenced in a predefined manner with respect to the relative position to at least one other longitudinal section module, in particular by means of several suitable form-fitting contours (reference system in particular integrally specified in the respective module), so that the greatest possible accuracy can be ensured when positioning relative to one another.
  • this makes it easier to handle and hold the individual modules, and on the other hand, it can also make the process of connecting/marrying modules in pairs easier.
  • the corresponding supporting structure components of the respective module are referenced/positioned two-dimensionally, i.e. in only one spatial plane. This also reduces the process complexity and can ensure a lean process, especially in connection with material-bonded joining/welding.
  • guideway device refers primarily to escalator devices (in particular including moving walkways) and moving walkway devices (the latter in particular in a stepless design in an at least approximately flat alignment or with a negligible gradient) as well as related passenger transport devices with a continuously rotating transport device.
  • a guideway device comprises, for example, segments or units forming the transport device, in particular steps or pallets, which are connected to driven chains or comparable drive means and guided in guide rails.
  • the guide rails as well as a/the chain (or a comparable traction means) and other components of the guideway device are held, for example, within load-bearing constructions or support structures extending substantially laterally therefrom in the axial direction, which are usually formed from two side wall units lying opposite one another and connected to one another via crossbeams and optionally also a floor unit, and can also comprise struts arranged in a lattice-like manner.
  • the term "guideway device” also refers in particular to modularly constructed guideway devices which are modularly constructed from several longitudinal sections or longitudinal section modules, each with an individual or longitudinal section-specific support structure and which can be assembled/mounted modularly.
  • the guideway devices described here can also each comprise moving walkway devices, i.e. at least approximately horizontally aligned guideway devices without steps but with individual guideway elements which are not intended to overcome an incline but form a largely flat route; in this respect, a reference to a bend or an inclined section is to be understood here to mean that the corresponding section is described largely independently of any incline actually realized.
  • the general term "assembly” or the more specific term “final assembly” generally refers to the assembly of the entire/complete support structure of the guideway device, which can also include all of the intended longitudinal section modules (two head modules and at least one intermediate module); this final assembly is also described here as a pairwise modular connection/marriage of the support structures of at least two longitudinal section modules, or at least comprising this connection step.
  • the term "assembly” can also include preparatory steps such as picking/providing/keeping components ready for a respective longitudinal section or module or for the entire guideway device; according to the present disclosure, the invention primarily relates to steps and aspects that are downstream of picking, i.e. do not include picking in the narrower sense.
  • module refers specifically to the assembly or assembly of only certain individual modules or their components in the corresponding module, for example specifically in the case of a head module, where, for example, components of a/the drive are installed in the upper head module, or guides, rails, cladding parts or components of the balustrade are (pre-)assembled in only one of the modules.
  • the assembly of components can take place at least partially in a phase in which the modules are still handled separately from one another, or in a phase in which the modules are already married to one another; this variation possibility applies, for example, to the individual steps/pallets; in this respect, too, the use of the term "assembly" is not to be understood as restricting certain phases of the process of creating the complete guideway device or its supporting structure.
  • longitudinal section module is to be understood in the sense of the present disclosure generally as a load-bearing longitudinal module of the guideway device, i.e. as a module that forms a longitudinal or length section of the guideway device and provides the support structure for it (i.e. a component of the guideway device in the corresponding length range that is at least structurally complete).
  • This term therefore includes the terms “head module” and “intermediate module”.
  • head module refers to a module arranged at one of the ends of the guideway device and refers optionally to both types of head modules (upper and lower head module, also referred to as upper part and lower part); in this respect, this term can equally refer to the module at the upper or lower end of the guideway device.
  • head modules In guideway devices designed as escalators, head modules usually extend over one or the angle of inclination of the guideway device and thus span the bend or the transition from the inclined longitudinal section to the respective horizontal longitudinal section.
  • the term "platform section” refers to the section of the respective head module that is aligned at least approximately in a horizontal plane in the intended arrangement; in this respect, when describing the arrangement/alignment of the respective head module, reference is also made to the alignment of this platform section (or its main extension plane), in particular if or when the absolute length of the platform section is greater than the absolute length of the inclined section.
  • the "connecting inclined section” (also referred to as a stub in the specialist literature) is to be understood in particular as the inclined/inclined section intended for connecting/marrying with another longitudinal section module, and this inclined section can be more or less long depending on the function of the respective head module; this means that the individual modules are intended to be connected to one another in the area of a/the intended inclined longitudinal section; if several intermediate modules are provided, the intermediate modules are first connected/married to one another or the respective head module and intermediate module are first connected, depending on the procedural preference.
  • the general term “longitudinal section” can refer either to a longitudinal section module or to a specific longitudinal section, in particular of the head module (i.e. platform section or inclined section).
  • longitudinal section compared to the term “longitudinal section module” refers, unless further specified, equally to the head sections and the at least one intermediate section and is used according to the present disclosure when modularity or a modular design or a strictly modular process is not necessarily required or can also be varied or modified according to the invention, or when reference is made to a process or a device-related state which is still prior to the intended modular construction of the individual modules, e.g. relating to connecting individual longitudinal sections of a head module to form the entire head module.
  • individual longitudinal sections are referred to without explicitly referring to them as longitudinal section modules, not only the individual modules but also longitudinal sections of an individual module can be affected, in particular a platform section (e.g. first longitudinal section) and an inclined section (e.g. second longitudinal section) of a head module, for which two sections a specific connection process can be provided (in particular in the area of the bend);
  • a platform section e.g. first longitudinal section
  • an inclined section e.g. second longitudinal section
  • individual longitudinal sections of a module can be positioned relative to one another by means of form-fitting contours, e.g. in connection with a material-locking connection of these longitudinal sections to create the entire supporting structure of the respective module.
  • A/the support structure of a/the guideway device or of a/the respective module can essentially be formed by opposing side wall units and cross members (also referred to as crossbars) connecting them, wherein a/the side wall unit is formed by at least one side wall and in particular by an upper chord and/or a lower chord; the modular manufacturing process described here can also include the connection of a floor unit to the side wall units; however, it has been shown that such a floor unit does not necessarily have to fulfill a support function, but is designed, for example, with regard to the function of collecting oil from a/the drive and, if necessary, draining it away, or is designed in an optimized manner with regard to a cover and/or accessibility from below to the support structure or the guideway device; in this respect, the floor unit is to be understood as an optional structural unit, which can also be functionally provided separately from the support structure, but which can optionally also take on an additional supporting load-bearing function if desired in individual cases.
  • side wall refers to a side structure which, for example, runs flat in only one side plane at least in sections, but alternatively or additionally at least in sections by profiles, struts or supports extending beyond one/the side plane formed and/or reinforced.
  • the side wall is made of structural elements or structural sections which, as flat structural sections, absorb forces in several directions and/or, as rod-shaped or strut-like structural parts/sections/elements, absorb the respective forces only along the longitudinal extent specified by the orientation (tension or compression); such components of the load-bearing structure can also be referred to by the English term “truss member” or "truss section”, whereby according to the present disclosure, a truss-like structure does not necessarily have to be present; the term “truss” can nevertheless be considered appropriate here, because the side wall usually has a truss-like structure at least in sections, i.e.
  • the side wall is therefore designed, for example, as a closed surface, as a pure truss or as a structure with parts (or sections) of closed surfaces and parts with a truss structure.
  • at least some of the load-bearing structural parts/sections of the side wall are made of flat material, in particular sheet metal, e.g. structurally flat sections or stiffening (in particular) curved L- or U-profile sections in the area of welded connections to other structural parts/elements/sections.
  • a “side wall unit” comprises the side wall described here and belts associated with this side wall, in particular an upper belt and a lower belt, wherein the belts can be formed integrally with the side wall, integrated or separate from one another. These belts are alternatively also referred to as bands.
  • the respective side wall/unit can also be understood as a side wall/unit provided in modules, depending on the reference to a/the respective phase of the manufacturing process of the individual modules or the entire guideway device.
  • the term side wall unit can refer to the entire side structure comprising upper and lower belts, and the term side wall can refer to the side structure arranged between the upper and lower belts.
  • chords refer to structural parts/elements extending longitudinally in the area of an upper edge or a lower edge of the side wall or corresponding load-bearing sections for absorbing loads in the longitudinal direction of the guideway device, in particular bending loads, which primarily lead to tensile stresses in the lower chord and to compressive stresses in the upper chord.
  • the chords are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles or hollow profiles and thus have a favorable area moment of inertia for absorbing the bending loads.
  • the chords therefore stiffen the supporting structure and form external corner points, whereby the chords and/or the side walls can optionally be used to attach further Components of the guideway device.
  • the belts can also be designed as components separate from the side wall; however, at least some of the belts are preferably formed in one piece with the side wall, for example by bending the side wall.
  • the upper belt is particularly preferably designed as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two further walls being formed by a flat material component that is also L-shaped and separate from the side wall.
  • the lower belt is also preferably designed in a similar way as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made from flat material in this area, and two walls being formed by the floor unit that is also L-shaped and made from flat material in this area.
  • the components forming the walls are preferably welded to one another.
  • the upper belt and/or the lower belt can also be provided entirely in one piece with the side wall or entirely separately from the side wall (particularly in the sense of a process variation).
  • Structurally loadable is understood to mean a point or component of the supporting structure that is temporarily loadable to absorb at least the forces resulting from the dead mass of the guideway device or the corresponding module, e.g. in connection with individual assembly steps. This term is used, for example, in relation to the reference points described here.
  • load-bearing is understood to mean a component or a part (section) of the supporting structure which is designed to withstand the prevailing static and dynamic forces and moments, even under continuous loading over several years, when the guideway device is used as intended.
  • connecting means in the sense of the present disclosure is to be understood as a screw connection or a rivet connection, in particular a so-called locking ring bolt connection, particularly in connection with a connection between modules.
  • the person skilled in the art can specify whether such a preferred rivet connection or locking ring bolt connection should be replaced in individual cases or at individual connection points by, for example, a screw connection.
  • the rivet connection or locking ring bolt connection preferably comprises at least one visual inspection marking, in particular one that lifts off the material.
  • the present invention is also based in particular on the concept that at least a significant portion of a side wall, an upper flange, a lower flange and/or the entire side wall unit, which portion defines the overall shape, is made of flat material, in particular sheet metal, with at least one reference point preferably being defined on the flat material.
  • a side wall, an upper flange, a lower flange and/or the entire side wall unit, which portion defines the overall shape is made of flat material, in particular sheet metal, with at least one reference point preferably being defined on the flat material.
  • the invention particularly preferably includes the teaching of introducing further references, in particular corresponding recesses (in the sense of additional component-specific assembly reference points) on the flat material in addition to the at least one reference point arranged in particular in the corresponding side wall during the course of the same processing method, on which further components can be arranged directly and thus in a defined position relative to the at least one (master) reference point with high accuracy.
  • references or reference recesses are also introduced in particular in areas of the flat material which can be subjected to further processing steps, in particular bending processes, following laser cutting, whereby the referencing concept described here can also be implemented for multi-dimensional positioning in space with respect to at least two or all three spatial directions.
  • the invention further includes the teaching that the reference point is defined by, for example, a circular recess or by its center, to which further positioning devices (i.e. assembly aids such as, for example, side support units) for positioning individual longitudinal sections or components can be clamped, for example.
  • the respective component with the reference point or the entire module or the entire guideway device is lifted at at least one reference point or supported around a reference axis formed by several reference points, e.g.
  • an upper chord or a lower chord can also be formed from a profile, whereby corresponding processing methods, in particular tube laser cutting methods, for forming a reference point and/or further references are also available for profiles.
  • components refers to components to be installed in the respective guideway devices or in the respective modules of the guideway device, e.g. relating to electrics, drive, guidance or the like. If a load-bearing function is to be fulfilled by a structural component, in particular for the intended continuous load, the term “load-bearing components” or structural parts/elements/sections is used in connection with the supporting structure.
  • structurally loadable reference point in the sense of the present disclosure is to be understood as an application point arranged in particular in the respective side wall, which transmits the forces into the supporting structure and via which the respective module can be lifted and/or supported in a predefined/predefinable positional relationship and preferably also tilted about a horizontal axis (in particular when stored about at least two reference points, in particular on opposite side wall sections, which form a structurally loadable reference axis) and in this way the assembly process can be supported, and on the other hand the individual components and/or modules can also be dimensioned relative to one another; in this respect, the term “longitudinal section-specific positioning reference” here declares the technical teaching of equipping a respective longitudinal section module with a module-specific position reference, via which the relative and optionally also absolute positioning can take place.
  • the respective module can also be advantageously moved on first and second support and movement devices or supports or rollable flat carriages, in particular without the need for rails or the like integrated into a floor; optionally, a side stop in the form of a guard rail or the like can be provided at the level of the support and movement devices to support an exactly aligned axial alignment of one or more modules.
  • the respective reference recess can be provided as part of a position reference coupling, which together with an assembly aid that can be provided at least as precisely/exactly as possible and e.g. a bolt plug connection provides a/the position reference coupling, preferably with three-dimensional positioning in space.

  • the support and movement devices described here by means of which the individual modules can be arranged, positioned and aligned, can also be provided by so-called trolleys or carts, which are available in many machine halls or production plants, especially if the trolleys or carts have a have integrated height and/or lateral adjustment. It has therefore been shown that the positioning accuracy described here cannot necessarily be achieved solely by means of the reference hole grid described here in predefined/standardized positioning means (see the disclosure of the positioning units equipped in particular with standardized guides or plug connections on alignment plates), but also by means of comparatively simply designed trolleys or trolleys, which can be used, for example, in conjunction with a traverse tree placed on them.
