Description

Technical area

The present invention relates to a support structure for a guideway device, in particular an escalator device, having two opposing side wall units, each with an upper chord, a lower chord and a side wall extending between the upper chord and the lower chord. Furthermore, the present invention relates to a longitudinal section module of a guideway device that can be assembled in modules, in particular an escalator device, with such a support structure and a corresponding guideway device.

Background of the invention

Support structures for guideway devices or guideway devices themselves are basically known from the state of the art. Support structures form the external supporting structure for components of the guideway device, such as guides with steps/pallets embedded therein, drives and electrical systems as well as for attachment and cladding elements and are usually made up of two side wall units that are opposite one another and connected via cross beams. The side wall units usually have profiles welded together as structural elements, from which lattice-like side walls and an upper and lower chord are formed.

The disadvantage of such support structures is that they have relatively large manufacturing tolerances, which are caused in particular by the welding of the profiles. Components of the guideway device that are attached to the support structure must therefore be positioned and/or aligned using very complex procedures with appropriate assembly aids before they are attached to the support structure. For this purpose, appropriate fastening means are designed for variable positioning/alignment of the component in relation to the support structure. and/or must be laboriously created manually after positioning and/or alignment.

Out of EP 1 321 424 B1 A supporting structure for an escalator or moving walkway is known, which has a lattice element that is designed as a single piece and as a flat, unprofiled, cut plate. The welding work required to build the supporting structure is thus reduced.

Description of the invention

Based on this situation, it is an object of the present invention to enable a simplified and safe positioning/alignment of components of a guideway device.

The object of the invention is achieved by the features of the independent main claims. Advantageous embodiments are specified in the subclaims. If technically possible, the teachings of the subclaims can be combined as desired with the teachings of the main and subclaims.

In particular, the object is accordingly achieved by a support structure for a guideway device, in particular an escalator device, comprising two opposing side wall units, each with an upper chord, a lower chord and a side wall extending between the upper chord and the lower chord, wherein a respective side wall has at least one first recess for positioning a support element on the side wall, wherein the at least one first recess is positioned in a defined manner relative to a reference point of the support structure and wherein the support element has at least one second recess for positioning and aligning at least one guide of the guideway device by striking against the second recess.

Advantageous aspects of the claimed invention are explained below and further preferred modified embodiments of the invention are described below. Explanations, in particular regarding advantages and definitions of features, are given in the Basically descriptive and preferred, but not limiting examples. If an explanation is limiting, this will be expressly mentioned.

If elements are designated by means of a numbering, for example "first element", "second element" and "third element", this numbering is intended purely for differentiation in the designation and does not represent a dependency of the elements on one another or a mandatory order of the elements. This means in particular that, for example, a device or a method does not have to have a "first element" in order to be able to have a "second element". The device or method can also have a "first element" and a "third element" without necessarily having a "second element". Several units of an element of a single numbering can also be provided, for example several "first elements".

In the sense of the present disclosure, the general term "guideway device" refers primarily to escalator devices 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 guides. The guides as well as a/the chain (or a comparable traction device) and other components of the guideway device are held, for example, within support structures extending longitudinally essentially laterally therefrom, 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. 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 individually created support structure, and which can be assembled/mounted in modules.

The support structure of the guideway device or the respective module is preferably formed essentially by opposing side wall units and cross members (also referred to as crossbars) connecting them, with each side wall unit being formed by at least one side wall and in particular by an upper flange and/or a lower flange. The modular manufacturing process described here can also include the connection of a floor unit to the side wall units, but 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 drive and, if necessary, draining it away, or is designed to be optimized 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.

The term "side wall" refers to a side structure that, for example, runs flat in only one side plane at least in sections, but is alternatively or additionally formed and/or reinforced at least in sections by profiles, struts or supports that extend beyond one/the side plane. In general, the side wall is made up of structural elements or structural sections that, as flat structural sections, absorb forces in several directions and/or, as rod-shaped or strut-like structural elements/sections, absorb the respective forces only along the longitudinal extension specified by the orientation (tension or compression). The side wall is therefore designed, for example, as a closed surface, as a pure framework or as a structure with parts of closed surfaces and parts with a framework structure. Optionally, at least some of the structural elements/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 elements/sections.

A "side wall unit" as understood in the present disclosure comprises the side wall described above as well as further structural elements/sections of this Belts associated with the side wall, in particular an upper belt and a lower belt, wherein the belts can be formed in one piece 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 of the entire guideway device. In this respect, the term side wall unit can refer to the entire side structure comprising the upper and lower belts, and the term side wall can refer to the side structure arranged between the upper and lower belts.

The terms upper chord and lower chord, which are also referred to together as belts, refer to structural elements or structural sections extending longitudinally in the area of an upper edge or a lower edge of the side wall 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 belts 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 belts therefore stiffen the support structure and form outer corner points, with the belts and/or the side walls optionally serving 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 integrally with the side wall, for example by bending the side wall. The upper chord is particularly preferably designed as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made of 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. Furthermore, the lower chord is preferably designed in a similar manner as a hollow profile with four walls, with two walls being formed by the L-shaped side wall made of flat material in this area and two walls being formed by the base unit that is also L-shaped and made of flat material in this area. The components forming the walls are preferably welded together. The upper chord and/or the lower chord 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).

A guide is provided in particular for guiding a guide roller or a chain roller of a step or pallet of a guideway device, on which the respective roller rests or is guided in this way. As an alternative to such a roller, a corresponding guided element is designed as a roller, sliding block or similar. The guide is provided as an alternative for guiding a handrail. The guide in particular has a running/sliding surface. In particular, in the guideway device, two guides are provided for each guided element, opposite one another in the transverse direction of the guideway device and arranged on respective side wall units, which must in particular be positioned/aligned in terms of their distance from one another for safe and trouble-free guidance.

Defined positioning is understood to mean that in the manufacture of the guideway device or the support structure, the elements that are positioned in a defined manner relative to one another are only positioned in relation to one another. If an element such as a recess, a fastening means or a connecting means is positioned in a defined manner relative to the reference point, only the distance from the reference point is taken into account during manufacture. Any dimensional inaccuracies of other components/elements are then irrelevant for the positioning of the element. A reference point is understood to be a material point on a component to which positioning in at least one spatial direction is possible with dimension accuracy. This is, for example, an edge or corner of a component, a connecting means provided on the component and/or a recess or projection provided in the component. In particular, a round recess is provided as the reference point, which is defined as a reference point by its center and enables the engagement of an assembly aid such as a bracket or a gauge.

The solution to the problem with the support structure described above now includes the teaching that on a respective side wall the support element is positioned at the first recess positioned opposite the reference point, for example by positive engagement in the first recess. The first recess is positioned in a defined manner relative to the reference point, i.e. arranged with high dimensional accuracy relative to the reference point, for example by producing the side wall using a correspondingly precise process or by introducing the first recess using a correspondingly precise device, so that the support element is positioned accordingly precisely on a respective side wall. By referencing the reference point on both side wall units and the aforementioned precision, the positioning of the guide on the support element is possible in such a way that alignment can advantageously be carried out without any further aid or further calibration. The striking and the resulting alignment takes place at least in one spatial direction, but preferably in all spatial directions on the support element or the second recess. The invention makes it possible in particular to align opposing and corresponding guides on the two side wall units or side walls in terms of their distance from one another for safe and trouble-free guidance by simply striking on the respective support elements, with all references provided for this purpose being positioned directly or indirectly in relation to the same reference point.

The present disclosure is based in particular on the concept that at least a significant portion of the side walls, which defines the overall shape, is made of flat material, in particular sheet metal, with at least one reference point being defined on the flat material. By means of processing methods with very low tolerances that are available today for flat materials, in particular by processing using laser cutting tools, reference can be made to this at least one reference point in the further course of assembly of the guideway device, so that assembly can be carried out with very small assembly tolerances and the guideway device can be manufactured with advantageously high dimensional accuracy. In this way, the comparatively exact relative or absolute positioning of individual components of the guideway device with respect to the at least one reference point can also be made possible, and further measures for aligning and positioning the components, in particular relative to one another, can largely be dispensed with. In particular, the invention includes the teaching that, in addition to the reference point arranged in particular in the corresponding side wall, a reference point can be defined on the flat material. at least one reference point in the course of the same processing method to introduce further references, in particular corresponding recesses such as the first recess (in the sense of additional component-specific assembly reference points), at which further components can be arranged directly and thus in a defined position relative to at least one (master) reference point with high accuracy. The references are also introduced in particular in areas of the flat material which can be subjected to further processing steps, in particular bending processes, following the aforementioned processing method, 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 described referencing system also has the advantage that a particularly light support structure is created compared to the usual truss construction.

The side walls are therefore preferably each formed essentially from a flat material, in particular from a metal sheet, wherein the first recess is formed by means of laser cutting in order to achieve the aforementioned advantages of a particularly precise arrangement of the first recess. Insofar as a recess is formed by means of laser cutting or by means of a laser cutting tool, the material is severed by a correspondingly aligned and designed laser beam. A (corresponding) laser cutting tool is designed in particular for processing from one direction, wherein a laser head is aligned perpendicular to the workpiece and is designed to be movable relative to the workpiece in a plane parallel to the workpiece. The laser cutting tool is then preferably intended for processing flat material, wherein the laser head can also be aligned in a manner deviating from its vertical orientation. A laser cutting tool can also comprise a laser head that can be spatially movable around a workpiece, in particular the profile, wherein recesses can be made particularly advantageously on the profile from any spatial direction and independently of the geometry of the profile. In addition, it is possible to create recesses in a wall of a profile with opposing walls, such as a hollow profile, without the laser beam reaching the wall behind the wall in its direction. damaged. Laser cutting is also known as tube laser cutting for profiles with opposing walls, especially hollow profiles.

In one embodiment, the support element forms at least one wall of a structural post placed on the side wall. A structural post is a structural element that runs along the side wall in a vertical direction and is preferably arranged at recurring intervals along the longitudinal extension of the side wall. In particular, the structural post serves to stiffen the side wall or the support structure and/or to absorb loads on the side wall or the support structure. The support element preferably extends vertically from the side wall and forms a hollow profile with an L-angle welded to the support element and the side wall. For this purpose, the side wall, the support element and/or the L-angle each have recesses and projections that engage with one another for positioning. The recesses and projections are preferably formed by means of laser cutting, with all parts of the structural post in particular being positioned in a defined manner relative to the reference point. By integrating the support element into the structural post, the support element is particularly well suited to supporting loads resting on the guides, or such loads are introduced into the side wall in a particularly favorable manner, namely at the rigid structural post. Furthermore, by integrating the support element, which is only made possible by the defined positioning of the parts to one another, the provision of separate support elements and structural posts is replaced, so that the support structure is designed with fewer components overall.

In a configuration of the aforementioned embodiment, the support element and/or the structural post is/are particularly preferably formed from a flat material, in particular from a metal sheet. The recesses and/or projections can then be formed thereon in a simple and particularly precise manner by means of laser cutting and a support structure is created that is particularly light compared to the usual framework construction. In particular, projections are formed on edges of the flat material by appropriate contouring.

Preferably - and essentially already described above - the at least one second recess is designed for positioning a guide for guiding a chain roller and/or for guiding guide rollers of at least one step or pallet of the guideway device. The dimensional accuracy achieved by the invention and the low tolerances when positioning and aligning the guide lead to particularly great advantages, especially with such chain or guide rollers, since precise alignment is essential for safe, quiet and trouble-free operation of the guideway device.

In a further embodiment, the support element has at least one third recess for receiving, in particular for positioning and aligning by striking against the third recess, a base of the guideway device. Such a base serves to cover the support structure or side wall unit to an inner side of the guideway device in an area above the steps or pallets. Advantageously, the base is also easily held securely positioned and aligned on the support element and no further support element or other fastening of the base to the support structure or side wall unit or side wall is required.

In yet another embodiment, the support element has at least one fourth recess for receiving, in particular for positioning and aligning by striking against the fourth recess, at least one handrail guide. A handrail is guided on such a handrail guide in a direction opposite to the direction of travel of the guideway device in the region of the support structure in order to form a circuit of the handrail. In accordance with the third recess with the base received thereon/in it, the fourth recess makes it possible to dispense with a further support element or to provide another means of fastening the handrail guide.

In one embodiment, the support structure has at least one fifth recess adjacent to the second recess, the third recess and/or the fourth recess for receiving a fastening means for fastening the guide, the base and/or the handrail guide. The guide, the base and/or The handrail guides are then easily fixed to the support element in the position/orientation defined by the attachment, so that a change in the defined position/orientation during operation of the guideway device is reliably avoided. The fastening means are designed as clamps or screw clamps, for example.

Alternatively or additionally, the second recess, the third recess and/or the fourth recess is/are designed for the direct fastening of the guide, the base or the handrail guide. The second recess, the third recess and/or the fourth recess are then designed, for example, for the guide, the base or the handrail guide to be clicked in. This achieves particularly simple fastening, in particular without any additional fastening means.

Furthermore, the second recess, the third recess and/or the fourth recess is/are preferably formed on the support element by means of laser cutting. The dimensional accuracy or the low tolerances achieved in accordance with the above-described referencing concept is/are then achieved for the second recess, the third recess and/or the fourth recess, so that guides, bases and/or handrail guides positioned/aligned thereon are particularly securely positioned and aligned.

Furthermore, at least one projection of the support element is preferably designed to engage in the first recess for positioning the support element on the side wall by means of laser cutting. The dimensional accuracy achieved according to the above-described referencing concept or the low tolerances is/are then achieved for the positioning/alignment of the support element on the first recess, so that guides, bases and/or handrail guides positioned/aligned thereon are particularly securely positioned and aligned.

The object is further achieved by a longitudinal section module of a modularly assembled guideway device, in particular an escalator device, having a support structure as described above. The term "longitudinal section module" is generally understood in the sense of the present disclosure as a longitudinal module of the The term "head module" is to be understood as a guideway device, i.e. as a module that forms a longitudinal or lengthwise section of the guideway device (i.e. a component that is at least structurally complete in the corresponding length range). This term therefore includes the terms "head module" and "intermediate module". The term "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 usually extend over one or the angle of inclination of the guideway device, i.e. they span the bend or the transition from the inclined longitudinal section to the respective horizontal section. In this context, 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/orientation of the respective head module, reference is also made to the orientation of this platform section (or its main extension plane), in particular if the absolute length of the platform section is greater than the absolute length of the inclined section. The term "connecting inclined section", which is also referred to in the literature as a stub, is also to be understood in particular as the inclined/inclined section intended for connecting/marrying with another longitudinal section module and 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 an inclined longitudinal section. 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).

Such a longitudinal section module has the advantages described above with regard to the support structure. In particular, in a longitudinal section module, it is provided that a connecting means serves as a reference point for forming a supporting module connection of the longitudinal section module with another longitudinal section module or that the connecting means is related to the same reference point are positioned. The further longitudinal section module can then have a corresponding absolute reference point or reference an absolute reference point of the longitudinal section module, wherein the absolute reference point is preferably also referenced during assembly of the guideway device. The longitudinal section module is preferably designed as an intermediate module between two head modules.

In one embodiment, the support element or a structural post integrating the support element forms a connection with a cross member for connecting two side wall units. In this way, the distance of the guides, bases and/or handrail guides in the transverse direction determined by the cross member and the support elements is determined particularly reliably or with small tolerances.

The object is also achieved by a guideway device, in particular an escalator device, having a support structure as described above. In particular, the guideway device has at least one longitudinal section module as described above. Such a guideway device has the advantages described above with regard to the support structure or with regard to the longitudinal section module.

Detailed description of the drawings

The described embodiments are merely examples that can be modified and/or supplemented in many ways within the scope of the claims. Each feature described for a specific embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an embodiment of a specific claim category can also be used in a corresponding manner in an embodiment of another claim category.

The Figures 1a to 1c show several longitudinal section modules 1.1, 1.2, 1.3 of a modularly assembled guideway device 1, namely Figure 1a a first longitudinal section module 1.1 designed as a lower head module, Figure 1b a second longitudinal section module 1.2 designed as an intermediate module and Figure 1c a third longitudinal section module 1.3 designed as an upper head module. The head modules extend beyond bends or have a bent stub. The longitudinal section modules 1.1, 1.2, 1.3 each have a support structure 2 with two side wall units 2.1, 2.2 extending mainly in a longitudinal direction L and cross beams 2.3 extending in a transverse direction Q. Each side wall unit 2.1, 2.2 in turn has a side wall 3, an upper flange 4.1 extending in the longitudinal direction L and a lower flange 4.2 extending in the longitudinal direction L.

The structure of the supporting structures 2 is shown in the Figures 1d and 1e shown in detail. The side wall 3 is made of a flat material in which structural sections 6.1, 6.2 are formed by recesses 5. The structural sections 6.1 divide the side wall 3 or the side wall unit 2 into fields. Furthermore, structural posts 7 are arranged or fastened, in particular welded, to the structural sections 6.1 and the cross braces 2.3 are arranged or fastened, in particular welded, to the structural posts 7. In the structural posts 7, the side wall 3 forms a first wall 7.1, a support element 11 a second wall 7.2 and an L-angle 23 a third wall 7.3 and a fourth wall 7.4, as in Figure 3 is shown in detail. Figure 3 shows a structural post 7 in the area of a bend in a head module. The side wall 3, the support element 11 and the L-angle 23 are each made of flat material, with the side wall 3 having laser-cut first recesses 24.1 for positioning the support element 11 on the side wall and the structural post 7 having further recesses 25, 26, 27 for positioning the L-angle 23 and the cross member 2.3 on the side wall 3 or the support element 11. The recesses 24.1, 25, 26, 27 are each assigned projections arranged on edges of the support element 7 and the L-angle 23 and also formed by means of laser cutting, which engage in these for positioning/aligning the components with one another.

The support element 11 protrudes vertically from the side wall 3 into an interior of the guideway device 1 and has a second recess 24.2 for receiving a guide 14.1, a third recess 24.3 for receiving a base 13 and further recesses 28, 29 for receiving further guides 14.2, 14.3. The recesses 24.1, 28, 29 are held by striking, both in the transverse direction Q and in a vertical direction H, so that the components received in each case are positioned and aligned, as described in more detail in Figure 2 is shown. Below the second recess 24.2 and the further recesses 28, 29, fifth recesses 24.5 are also arranged, which are designed to receive a fastening means (not shown in more detail), such as a clamp.

The side wall 3 is also integrally formed with the upper flange 4.1 and the lower flange 4.2. The flat material forming the side wall 3 thus forms a first Wall 8.1 and a second wall 8.2 of the upper chord 4.1 is formed by an L-shaped bent from the first wall 8.1. A third wall 8.3 and a fourth wall 8.4 of the upper chord 4.1 are formed by a further element made from an L-shaped bent flat material and welded to the flat material forming the side wall 3. In the same way, a first wall 9.1 is formed by the flat material forming the side wall 3, bent from the side wall 3 in an L-shape, and a second wall 9.2 of the lower chord 4.2 is formed by an L-shaped bent from the first wall 9.1. A third wall 9.3 and a fourth wall 9.4 of the lower chord 4.2 are formed by an L-shaped bent floor unit 10.

Again with reference to the Figures 1a to 1c The longitudinal section modules 1.1, 1.2, 1.3 are shown with several components of the guideway device. The lower head module ( Fig. 1a ) a comb plate 12, a base 13, a balustrade 16 with a handrail 17 arranged thereon and several guides 14.1, 14.2, 14.3 for chain rollers, step/pallet rollers and/or a handrail (not shown). Corresponding guides 14.1, 14.2, 14.3, a base 13 and a balustrade 16 are also in the intermediate module ( Fig.1b ). The guides 14.1, 14.2, 14.3 rest on the support elements 7. The upper head module ( Fig. 1c ) has, in addition to the components already present in the lower head module and/or intermediate module, a drive 15 for driving a chain and/or a handrail circuit. In the illustration of the upper head module, a balustrade 16 provided is not shown.

The longitudinal modules 1.1, 1.2, 1.3 each have reference points 18 on the supporting structures 2, or side wall units 2.1, 2.2, or side walls 3 in the flat material, which in Fig. 1d are shown. In the Figures 1a to 1c the reference points 18 are covered by mounting brackets 19, which in turn are attached to slides 20. By hanging the longitudinal sections 1.1, 1.2, 1.3 on the reference points 18, it is possible to refer to the reference points 18 again and again during assembly and, ideally, only when positioning/aligning components. The reference points 18 are formed on the flat material during the manufacture of the side walls 3 by laser cutting, whereby all other points on the flat material are formed by laser cutting due to the precision typical for laser cutting. introduced recesses 22, 24.1, 25 or cutouts are positioned exactly opposite the reference points 18 and can therefore serve as references for the positioning/alignment of components, in particular the support element 11. In particular, this also applies to the connecting center 21 and slots 22 provided for connecting the longitudinal section modules 1.1, 1.2, 1.3 for receiving components of the guideway device 1. The recesses 24.2, 24.3, 24.4, 24.5 26, 27, 28, 29 are also formed on the respective components by means of laser cutting. Projections associated with the recesses 24.1, 25, 26, 27 for positioning/aligning the components with respect to one another are also formed on the respective components, in particular on the support element 11, by means of laser cutting, so that the reference to the reference point 18 continues through all components by precisely positioning the components with respect to one another, in particular between the side wall 3 and the support element 11. By means of the reference points 18 and in particular the suspension of the longitudinal section modules 1.1, 1.2, 1.3, an exact alignment of the longitudinal section modules 1.1, 1.2, 1.3 with respect to one another is also possible when they are connected to one another via the connecting means 21.
