Description

Technical Field

[0001] This invention relates to a track fixing device for fixing guide rails in sections to a guide rail system of an escalator or moving walkway. Background Technology

[0002] Using this guide rail system, the running elements are supported and guided along their circular tracks, where the operation of these running elements should be as quiet and vibration-free as possible. In escalators, the guide rail system is also used to horizontally guide the foot surfaces of the running elements, designed as treads, in the horizontal and ascending areas and in the transition sections when traveling through the upper section.

[0003] An escalator structure is disclosed in EP1902996B1, wherein a guide rail system with guide rail segments is provided in the turning area. These guide rail systems essentially have two vertically arranged side plates interconnected by crossbeams. The guide rail segments are welded to these side plates. To ensure precise alignment of the guide rail segments, special receiving devices are used during manufacturing. These receiving devices include clamping devices for the precise arrangement of components to be welded together, and the parallelism and alignment of the rails are ensured with sufficient precision through appropriate machining. Therefore, for assembly, the guide rail segments are held in a rigid mutual engagement with the clamping devices and connected to them by precision welding. Even small deviations can lead to so-called "misalignment" of the running elements, causing increased wear and thus higher energy consumption and a shorter service life.

[0004] This level of precision can only be achieved in the manufacturer's factory in a workplace prepared for this purpose, and not at the point of use, such as when worn sections of the guide rails of an existing escalator or moving walkway must be replaced.

[0005] Although guide rail sections can be separated from the side plates using a cutting machine, the equipment and labor costs involved in welding new guide rail sections at the point of use are significant, making it far from a smooth and cost-effective assembly. Furthermore, despite this considerable expense, the required level of synchronization of the operating components cannot be guaranteed. This is because the side plates of the guide rail system are assembled into the supporting structure of the escalator or moving walkway, and this occurs due to the introduction of thermal deformation into the structure. This thermal deformation, due to the surrounding trusses, cannot be eliminated by subsequent cold and hot straightening. Moreover, welding work is prohibited on existing escalators or moving walkways in many locations due to fire safety regulations.

[0006] DE102018213647A1 discloses a track fixing device that eliminates the need for welding sections of the guide rail, as the device has an integral track receiving portion and two fastening bolts. The track receiving portion can be inserted into a hole in the side panel from the rear side of the escalator. The track fixing device, passing through the side panel, receives the guide rail disposed on the front side of the side panel in its track receiving area. By tightening the fastening bolts, the guide rail is tensioned relative to the front side of the side panel, as it is clamped between the nose-shaped portion of the track receiving area and the side panel. However, this track fixing device can only be used when both sides of the side panel are accessible.

[0007] The problem, however, is that the side panels assembled in the support structure can only be accessed from the front or side of the guide rail, where the guide rail is segmented and welded there, and not from the rear. This is because the components of the support structure at the point of use, and especially the walls of the recesses in the building that accommodate escalators or moving walkways, block the entrance to the back or opposite side of the side panels. Summary of the Invention

[0008] Therefore, the object of the present invention is to provide a track fixing device for fixing guide rail segments, which enables precise and simple assembly on the side plate of the guide rail system, especially at the place of use.

[0009] This objective is achieved by a track fixing device for securing guide rails in sections to a guide rail system of an escalator or moving walkway. The guide rail system has at least one side plate with perforations, wherein the perforations extend in their planar direction with a perforation length greater than their width. Planar extension refers to the size of the perforation extending in the side surface of the side plate. In other words, this relates to the cross-section of the perforation defined by the perforation length and width, which is preferably constant over the entire thickness of the side plate.

[0010] The track fixing device includes a track receiving part, a threaded connection device, and a tensioning locking element. These components can be brought from a pre-assembled state to a final assembled state. In the pre-assembled state, the tensioning locking element is connected to the track receiving part by means of the threaded connection device in such a way that the tensioning locking element can pivot about the central longitudinal axis of the bolt relative to the track receiving part.

[0011] The track receiving part has a track receiving area and a support surface. In the final assembled state, the support surface faces the side plate and supports it, and the guide rail is segmentally fixed in the track receiving area. The tensioning locking member is coordinated in length and width with the perforation width and length in such a way that, in the pre-assembled state, the tensioning locking member can pass through the perforation in a first position, and in a second position, in the final assembled state, it can be supported on the material of the side plate surrounding the perforation. In other words, in the final assembled state, the area of ​​the track fixing device extends through the perforation and clamps the edge portion of the perforation of the side plate between the support surface and the surface of the tensioning locking member facing and abutting the side plate. This achieves very stable and wide support for forces acting on the track receiving part and which must be supported by the side plate.

[0012] It should be mentioned here that the guide rail or guide rail segment to be fixed can be secured to the rail receiving part by means of other fixing mechanisms, such as bolts, pins, rivets, clamps, etc. In one embodiment, the rail receiving part may have a support surface and a protrusion in the rail receiving area. Here, the width of the support surface defined by the protrusion is slightly shorter than the width of the guide rail. If the threaded connection of the rail fixing device is now tightened, the support surface is supported on the side plate on one hand, and the guide rail or guide rail segment is clamped between the side plate and the protrusion on the other hand. This is more precise because a large leverage effect can be obtained with respect to the clamping force between the side plate and the protrusion by providing a threaded connection between the support surface and the protrusion.

[0013] Regarding the cross-section of the tensioning locking element that will pass through the perforation, any shape can be considered, as long as it allows the tensioning locking element to be inserted through the perforation in a first position and then pivoted to a second position where the side plate is located. For ease of manufacturing, the outline of the tensioning locking element, or the cross-section to be penetrated, has a rectangular shape that corresponds to the planar extension of the perforation.

[0014] To simplify assembly, a pivoting counterweight can be provided on the tensioning locking member, which causes the pre-assembled track fixing device's tensioning locking member to pivot autonomously from a first position to a designated second position due to gravity after it passes through the perforation.

[0015] To reinforce the threaded connection of the final assembled track fixing device, anaerobic or microencapsulated adhesive materials can be used. During pre-assembly, the anaerobic adhesive is applied to the threads so that it is only present between the bolt and nut threads when the bolt is tightened. Bolt application is very simple; the bolt manufacturer has already applied microencapsulated adhesive to the bolt threads, and the adhesive is released by screwing it into the nut threads. Of course, other thread-fastening methods are also feasible, among which the most reliable and simplest possibility lies in providing sufficient extension length for the threaded connection.

[0016] Furthermore, the track fixing device may include mating brackets that can be fixed to the side plate. When the track fixing device is in its final assembled state, the guide rail segments fixed to the side plate are positioned between the track receiving portion and the mating brackets. Therefore, these mating brackets prevent the guide rail segments from potentially being lifted off the track receiving portion.

[0017] In one embodiment of the track fixing device, an anti-torsion device can be provided on the tensioning locking member. With this anti-torsion device, the torque applied to the tensioning locking member via the threaded connection can be profiled and supported in the perforation. This facilitates the assembly process and, on the other hand, prevents the anti-torsion device from pivoting even when the preload of the tightened threaded connection is insufficient, due to vibration itself. To enable the tensioning locking member to pivot from the first position to the second position, it is only necessary to ensure that, in the pre-assembled state, the tensioning locking member is spaced apart from the track receiving portion to such an extent that the anti-torsion device of the track receiving portion does not engage with the perforation profile.

[0018] Alternatively, or in combination with the aforementioned anti-torsion device, in another embodiment of the track fixing device, the anti-torsion device can be installed on the track receiving portion. With the aid of this anti-torsion device, the torque applied to the track receiving portion via the threaded connection can also be supported in the perforation with a surface-locking mechanism.

[0019] To simplify the assembly of the guide rail segments, pre-assembled rail fixing devices are preferred. In the pre-assembled state, the rail receiving part is connected to the tensioning locking member via a threaded connection. To secure the pre-assembled rail fixing device to the side plate, a pre-set assembly gap must be established between the rail receiving part and the tensioning locking member, this gap being greater than the thickness of the side plate in the perforated area. This is because otherwise, the tensioning locking member would still partially extend into the perforation and therefore could not pivot.

[0020] The aforementioned track fixing device is also applicable to guide rail systems for escalators or moving walkways, wherein the guide rail system has at least one guide rail segment and at least one side plate with at least one perforation. If no perforation is present, at least one perforation can be cut into the side plate at a suitable location, for example, using a template and suitable tools. Here, the perforation must have a perforation length in its planar extension, said perforation length being greater than its perforation width. At least one track fixing device of the aforementioned type can be arranged in said at least one perforation, by means of which the at least one guide rail segment can be fixed to the at least one side plate.

[0021] Therefore, this track fixing scheme is particularly suitable for escalators or moving walkways with at least one guide rail system, wherein the guide rail system has at least one side plate on which guide rail segments can be fixed.

[0022] During the maintenance or modernization of the guide rail system of an escalator or moving walkway, various steps are required. The guide rail system includes at least one side plate with at least one perforation. If no perforation exists, it can be created as described above. If necessary, it is easier to assemble a new side plate with a corresponding opening, provided that the new side plate is secured to the support structure of the escalator or moving walkway using a threaded connection and is not welded to it. As mentioned above, the perforation must have a perforation length greater than its width within its planar extension. To secure the guide rail sections to the guide rail system, the rail fixing device is pre-assembled by connecting the rail receiving part to the tensioning locking member using a threaded connection. Here, a pre-set assembly gap is established between the rail receiving part and the tensioning locking member, which is greater than the thickness of the side plate in the perforated area.

[0023] In another step, the tensioning locking member of the pre-assembled rail fixing device is brought into a first position and thereby aligned with the perforation length and width according to its length and width. In another step, the tensioning locking member can be guided through the perforation until the support surface of the rail receiving part abuts against the side plate. Then, the tensioning locking member is pivoted about the central longitudinal axis of the threaded connection and thereby brought into a second position. Next, in another step, the rail fixing device is brought into its final assembly state by tightening the threaded connection with a pre-given bolt tightening torque. Here, the tensioning locking member should remain in the second position until it is positioned on the material surrounding the perforation of the side plate and the support surface of the rail receiving part and / or the rail segment to be fixed is pressed against the side plate. The retention of the tensioning locking member in the second position can be achieved, for example, by means of the described anti-torsion device or by means of a screwdriver that is temporarily inserted through the perforation from the side during tightening of the threaded connection and thus prevents further pivoting of the tensioning locking member. Attached Figure Description

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings, which should not be construed as limiting the invention.

[0025] Figure 1 The middle longitudinal section shows the portion of the escalator located on the lower floors of the building, which has a supporting structure and a guide rail system installed in the supporting structure.

[0026] Figure 2 The track fixing device in a pre-assembled state is shown in a 3D diagram;

[0027] Figure 3 The track fixing device is shown in a 3D diagram, arranged from a side view accessible to the assembler. Figure 1 The side plate of the guide rail system shown in the figure; and

[0028] Figure 4 The diagram is presented in three dimensions, showing a view from a side inaccessible to the assembler. Figure 3 Track fixing device in the middle.

[0029] The accompanying drawings are schematic only and are not to scale. The same reference numerals in different drawings denote the same or serve the same function of features. Detailed Implementation

[0030] Figure 1 The portion of the escalator 1 located on floor E1 below building 3 is shown in a mid-section longitudinal view. The escalator 1 has a support structure 5 and a guide rail system 7 assembled within the support structure 5. The guide rail system 7 includes two side panels 9 (only one is shown due to the mid-section longitudinal view), with a step belt (not shown) between the two side panels guided on guide rail segments 11, 13. To keep the structural width of the escalator 1 relatively small, the side panels 9 are arranged close to the laterally extending structural elements (such as uprights 15 and braces 17) of the support structure 5. The walls 19 of building 3 are typically connected to the outer side of the support structure 5 at small intervals, making the faces of the side panels 9 facing the structural elements 15, 17 of the support structure 5 inaccessible for assembly work. However, when the step belt has been removed as shown, the side of the side panels 9 facing away from the structural elements 15, 17, on which the guide rail segments 11, 13 are arranged, is readily accessible.

[0031] Using a cutting machine, the guide rail segments 11 and 13, welded to the side plate 9 and to be replaced, can now be removed. The welds to be separated are typically arranged in areas known as welding windows. These welding windows are rectangularly designed and therefore appear as pre-existing perforations 21, which can be used to assemble the new guide rail segments 11 and 13. A rail fixing device 23 is provided for assembling the guide rail segments 11 and 13.

[0032] The perforation 21 has a rectangular cross-section in its planar extension, the cross-section having a perforation length L. s and perforation width B s Wherein, the perforation length L s Significantly larger than the perforation width B s The lower guide rail segment 13 is also welded to the side plate 9. The upper guide rail segment 11 has been replaced, so it is fixed to the side plate 9 by the rail fixing device 23.

[0033] like Figure 2As shown in the 3D diagram, the track fixing device 23 mainly includes: a track receiving part 25, a threaded connection device 27, and a tensioning locking element 29. The track receiving part 25 has a track receiving area 31 and a support surface 33. In the final assembled state, the support surface 33 rests on the side plate 9. The track receiving area 31 basically includes a support surface 35 and a protrusion 37. The following description, in conjunction with... Figure 3 and Figure 4 The description will further elaborate on the detailed functions of protrusion 37.

[0034] Tensioning locking element 29 in its length L R and width B R The aspect is in the following manner with the perforation width B of the perforation 21. s and perforation length L s (See Figure 1 In coordination with each other, the tension locking element 25 is in a pre-assembled state. Figure 2 The first position shown allows passage through the perforation 21, and the second position is in the final assembled state (see...). Figure 4 It can be supported on the material surrounding the perforated 11 of the side plate 9.

[0035] In other words, in the final assembled state, the middle region of the track fixing device 23 extends through the perforation 21 and clamps the perforation 21 or the edge portion of the side plate 9 between the support surface 33 and the surface 37 of the tensioning locking member 29 facing and abutting the side plate 9. This achieves very stable and wide support for forces that may act on the track receiving part 25 and must be supported by the side plate 9.

[0036] like Figure 2 As shown, to simplify the assembly of guide rail segments 11 and 13, it is preferable to pre-assemble the rail fixing device 23. In the pre-assembled state, the rail receiving portion 25 is connected to the tension locking member 29 via a threaded connection device 27. Furthermore, the tension locking member 29 is connected to the rail receiving portion 25 via the threaded connection device 27, allowing the tension locking member 29 to pivotally support relative to the rail receiving portion 25 about the central longitudinal axis 43 of the bolt or threaded connection device 27. For subsequent fixing of the threaded connection device 27, an anaerobic adhesive material can be applied to the area indicated by arrow A. Of course, bolts can also be used for the threaded connection device 27, which already have a micro-encapsulated adhesive material applied to their threads by the manufacturer.

[0037] In order to secure the pre-assembled track fixing device 23 to the side plate 9, a pre-set assembly gap t must be provided between the track receiving part 25 and the tensioning locking member 29. This assembly gap is greater than the thickness s of the side plate 9 in the area of ​​the perforation 21 (see...). Figure 3This is because otherwise the tension locking element 29 would still partially extend into the through hole 21 and therefore could not pivot.

[0038] To further simplify assembly, a pivoting counterweight 45, schematically shown by dashed lines, can be arranged on the tensioning locking member 29. This pivoting counterweight causes the pre-assembled tensioning locking member 29 of the track fixing device 23 to pivot autonomously from a first position to a designated second position due to a torque M caused by gravity after passing through the through-hole 21. Of course, this pivoting counterweight 45 is not mandatory, and the torque M can also be generated by a screwdriver and transmitted to the tensioning locking member 29 through the threaded connection device 27.

[0039] The final assembly state of the track fixing device 23 is described below. Figure 3 and Figure 4 As shown in the image. Figure 3 It shows in Figure 1 A three-dimensional detail view of the track fixing devices 23, indicated by arrow X. All others are shown in... Figure 1 The track fixing device 23 shown is preferably the same as the track fixing device 23. Figure 3 The track fixing device 23 is shown here from the side of the side panel 9, which is easily accessible to the assembler. Figure 4 Shown in three dimensions from a perspective that is difficult for assemblers to access. Figure 3 The same track fixing device 23.

[0040] The track fixing device 23 mounted on the side plate 9 has a track fixing device 23 with ... Figure 2 The components shown in the figure. Here, the width W of the support surface 35 of the track receiving part 25, defined by the protrusion 37, is... A Slightly shorter than the width W of the guide rail segment 11 located on the support surface 35 T If now tighten the threaded connection device 27 of the track fixing device 23 (in Figure 3 (shown via its central longitudinal axis 43), so the support surface 33 supports the side plate 9 on one hand and clamps the guide rail or guide rail segment 11 between the side plate 9 and the protrusion 37 on the other hand. However, this is only possible if there is always a gap Z between the rail receiving part 25 and the tension locking member 29 in the tightened threaded connection device 27.

[0041] exist Figure 4The operation of the anti-torsion device 39 constructed on the track receiving part 25 is also clearly visible. With the aid of this anti-torsion device 39, the torque M applied to the track receiving part 25 via the threaded connection device 27 is surface-locked and supported in the through hole 21. With this torque, the tension locking member 29 should pivot during the assembly process. This simplifies the assembly process and prevents the track receiving part 25 from rotating before the threaded connection device 27 is tightened and before the guide rail segment 11 is against the support surface 35. Furthermore, the weight of the step belt acting on the guide rail segment 11 is surface-locked by the anti-torsion device 39, thus requiring the threaded connection device 27 to be designed in a light-load manner to achieve, for example, sufficient frictional fit between the support surface 33 and the side plate 9.

[0042] like Figure 3 As shown, the track fixing device 23 may also include a mating bracket 47, which in this embodiment can be fixed to the side plate 9 by means of bolts 49. When the track fixing device 23 is in the final assembled state, the guide rail segment 11 fixed to the side plate 9 is disposed between the track receiving part 25 and the mating bracket 47. Therefore, the mating bracket 47 prevents the guide rail segment 11 from potentially being lifted off the track receiving part 25.

[0043] Although Figure 1 A portion of the escalator 1 is shown, but it is clear that the track fixing device 23 can also be used for the guide rail system 7 of the moving walkway. Furthermore, as an alternative to this, or in conjunction with... Figure 2 The anti-torsion device 39 assembly shown can also be fitted with a similar locking anti-torsion device 51 on the tensioning locking member 29. With the aid of this locking anti-torsion device 51, the torque M applied to the tensioning locking member 29 via the threaded connection 27 can also be form-locked and supported in the through hole 21. However, during assembly, care must be taken that the assembly gap t be large enough so that the locking anti-torsion device 51 is located outside the through hole 21 for pivoting. After pivoting, the entire track fixing device 23 can be slightly pulled back until the locking anti-torsion device 51 is inserted into the through hole 21. Thereafter, the threaded connection 27 can be tightened with the set tightening torque.

[0044] Finally, it should be noted that concepts such as "having" or "comprising" do not exclude other elements or steps, and terms such as "an" or "a" do not exclude multiple. Furthermore, it should be pointed out that the features or steps described with reference to one of the above embodiments can also be used in combination with other features or steps of the other embodiments described above. Reference numerals in the claims should not be considered limiting.
