Description

TECHNICAL FIELD

[0001] The invention relates to a protection device during assembly work on a passenger transportation device designed as an escalator or moving walk, an assembly unit and a method for assembling such a passenger transportation device. BACKGROUND

[0002] Passenger transportation devices designed as escalators or moving walks are used in architectural structures of the public sector, for example in train stations, subway stations, airports and shopping centers, cultural centers and the like. Escalators or moving walks have a load-bearing structure, which is designated as a support structure. This structure is usually a frame structure, which is manufactured as a whole unit by the manufacturer or is subdivided into support structure modules. The support structure or its support structure modules, precisely the frame structure modules, are constructed in the building, for example the support structure connects two floors of a building. In this support structure the movable components of the escalator or moving walk are arranged, for example the step or slat belt, the rotating handrail belt, the deflection axles, the drive axles and the components of the drive motor and gear and the like. Furthermore, the fixed components of the balustrade, the comb plate, the bearing points, the rollers and guide rails, the controllers, the monitoring system, the safety system and the like are also firmly connected with the support structure. Usually, escalators and moving walks are completely assembled in the factory of the manufacturer and are delivered from the manufacturer's factory to the architectural structure and there to the support points provided for this purpose, either as a whole or due to the subdivision into sections.

[0003] The complete constructed passenger transportation device of the above-mentioned type or its sections have a relatively large cross section, which sometimes causes considerable problems when a new escalator or a new moving walk is to be introduced into an existing architectural structure. In order to reduce the cross section to be delivered from the factory of the manufacturer to the support points of the architectural structure, which receives the escalator or moving walk, the balustrade is usually not assembled in the factory of the manufacturer, but is dismantled into its components and is provided as an accessory. A transparent balustrade with balustrade panels made of glass is also advantageous in that the transparent balustrade can be significantly better protected during transport than a balustrade assembled in an exposed position on the support structure. In order to be able to firmly connect the components of the balustrade to the support structure, balustrade clamps are firmly assembled on the support structure, in which the balustrade components, in particular the balustrade panels made of glass, can be firmly clamped.

[0004] However, since there is no guardrail, the work area of the assembly personnel on the support structure has to be specially secured. For this purpose, WO 2019 / 185573 A1 proposes a protection device designed as a maintenance guardrail, which can be firmly clamped to the upper belt of the support structure by means of a clamping device formed on the support. This protection device is easy to assemble or disassemble. However, due to its clamping structure, this protection device is very expensive and requires the upper belt of the support structure to be freely accessible. This means that, for example, the cladding elements of a guardrail base arranged between the support structure and the guardrail to be assembled cannot be assembled. Furthermore, the profiles for the upper belt of the support structure do not always have the same cross-section, so that this clamping device cannot be used universally. JP 2014141343 A also discloses a corresponding maintenance guardrail. SUMMARY

[0005] Due to the above-mentioned problems, the object of the present application can be seen in proposing a protection device which is less expensive to produce, can be used for various support structure configurations and, if necessary, can be more easily connected to the support structure.

[0006] The object is achieved by a protection device for protecting assembly personnel during assembly work on a personnel transportation device designed as an escalator, staircase or moving walkway.

[0007] The personnel transportation device has at least one clamping device for a guardrail panel, for which the guardrail panel comprises a panel clamping area which is designed to match the clamping device in order to be firmly clamped by the clamping device. Such a clamping device is disclosed, for example, in US 2015122612 A1. The protection device comprises at least one barrier device and at least one support. The at least one barrier device and the at least one support are connected to or connectable to one another. The barrier device extends transversely to the support and in the longitudinal extension of the personnel transportation device at least during assembly work. In order to secure the protection device on the personnel transportation device, the support has a foot region with a clamping area at one end thereof. This clamping area is designed in terms of its configuration and dimensions to be nachempfinden to the panel clamping area and serves to be held in the at least one clamping device of the personnel transportation device in a firmly clamped manner.

[0008] In other words, in a personnel transportation device in which no guardrail is assembled, the clamping device of the guardrail can be used to temporarily receive and firmly hold the protection device. Thus, existing components of the personnel transportation device are used to secure the protection device. This makes it unnecessary to have complex additional components on the personnel transportation device, which are only provided for receiving the protection device and then no longer used.

[0009] In one design of the protection device, the foot region can have a hinge arranged between the support and the clamping region. Thereby, the support can be pivoted between a transport position and an assembly position. This construction makes it possible for the protection device to be firmly clamped in a clamping device provided for this purpose by means of the foot region of the support already in the manufacturer's factory. The support, and possibly also the barrier device connected thereto, which is firmly clamped in the guardrail clamp, is then pivoted into the transport position. In this case, the transport position is a position in which the support extends substantially horizontally and in a direction transverse to the longitudinal extent of the personnel transport device.

[0010] In other words, the transport position makes it possible for the construction height of the personnel transport device to be kept as low as possible with the protection device already assembled, in order to be transported between the manufacturer's factory and the support points provided for it in the building. Once the personnel transport device is used in the support points provided for this purpose in the building structure, the protection device or the support thereof can be pivoted into the assembly position. Here, the assembly position is generally understood to mean the vertical standing of the support. Alternatively, more simply, it is possible for the protection device to be placed in a lying position relative to the personnel transport position at the manufacturer's factory and to be unfolded and secured in a standing position at the construction site.

[0011] In order to prevent the support from being folded back from the assembly position into the transport position unintentionally, in a further design variant the support can have a locking device. The locking device is designed to lock the pivoting of the hinge at least in the assembly position.

[0012] In a first design variant of the locking device, a threaded section can be formed between the clamping region and the hinge, on which a fixing nut is arranged. The fixing nut can be screwed onto the locking face of the hinge or of the support, which is pivotable to the threaded section, in a locking manner.

[0013] In a second design variant of the locking device, a flange having openings can be arranged on each of the two parts of the hinge which are connected to one another in a hinged manner. The openings are positioned in the flange in such a way that they are arranged flush with one another in the assembly position. Furthermore, there is a locking element which can be arranged to protrude from the openings of the two flanges. In this position, the locking element can lock the hinge. For example, a bolt, a screw, a split pin or the like can be used as the locking element in order to hold the two flanges together and thus lock the hinge.

[0014] In a third design variant of the locking device, a detent mechanism having a spring element and a detent element loaded by the spring element can be present in the region of the hinge. Here, in the assembly position, the hinge is locked by the detent mechanism autonomously. For example, a detent bolt or a pawl which locks the hinge in the assembly position can be used as the detent element.

[0015] In another design of the protection device, at least one support of the protection device can have a receiving portion, through which the barrier device can be arranged. In other words, along the longitudinal extension of the personnel transportation equipment, the supports can be individually firmly clamped into the clamping device and the receiving portions of the supports can be arranged with the barrier device, so that the barrier device connects the supports to one another and thus forms a continuous railing.

[0016] The barrier device can be a handrail, a rod, a slat, a rope or the like.

[0017] In another design of the application, at least two supports can be firmly connected with at least one barrier device and form a rigid railing. However, it must be ensured that the spacing of the supports coincides with the spacing of the clamping device. In order to avoid this dependency, all supports of the rigid railing can have a common clamping region.

[0018] In a preferred design, the barrier device can be designed to hang a personal safety device on the barrier device to provide additional safety for the assembly personnel. The barrier device is therefore preferably rod-shaped (circular, oval, or with significantly rounded edges, rectangular or square cross-section) and the safety device has a device such as a spring hook, through the eye of which the barrier device is arranged. The barrier device designed as a rod for hanging a personal safety device can be arranged above or below the hinge. The installation below the hinge has the advantage, for example in terms of the dual function as a common clamping region for connecting a plurality of supports, that the forces and bending moments occurring on the supports in the event of a possible fall are smaller than if the personal safety device is installed on a barrier device arranged above the hinge. A further equally important advantage of the personal safety device that can be hung below the hinge is that the safety device can be used or hung even if the protection device is folded. However, the position of the rod-shaped barrier device can be realized at any height of the protection device and depends on the design of the clamping device and the support structure of the personnel transportation equipment.

[0019] In order to enable the supports to be clamped sufficiently firmly in the clamping device, the clamping region of the supports preferably has two clamping faces designed parallel to one another. The distance between the clamping faces is preferably equivalent to the thickness of the railing panels or glass panels of the personnel transportation equipment, which are provided to be firmly clamped in the clamping device after removal of the protection device.

[0020] As already mentioned, the protection device instead of the guardrail can be fixed in the manufacturer's factory on a personnel transport device which is otherwise completed. The personnel transport device and the protection device form an assembly unit, the personnel transport device having at least one clamping device, at least one clamping region of the protection device being firmly clamped in the at least one clamping device of the personnel transport device. The protection device is preferably brought to a transport position in the manufacturer's factory, the assembly unit is then loaded and transported to the building structure at the destination thereof. When the assembly unit has reached the designated support site of the building structure, the support of the protection device can be pivoted into the assembly position and fixed. The safety device is fixed in the assembly position by means of a locking hinge.

[0021] Escalators and moving walks are usually designed so slender that they cannot be transported as a whole on a transport vehicle between the manufacturer's factory and the building structure provided therefor. Such slender personnel transport devices are usually subdivided into sections and transported. Once at the building structure, the individual sections are connected to one another and fitted into the support site provided therefor in the building structure. In the context of the present invention, such sections of the personnel transport device can also be logically provided with at least one protection device and thus form an assembly unit. This is particularly advantageous in that the protection device can be moved from the transport position to the assembly position before the individual sections are assembled to the whole personnel transport device in order to fully protect the assembly personnel participating in the connection of the sections.

[0022] The protection device can be used as follows. The method for assembling a personnel transport device designed as an escalator or moving walk in a support site of a building structure provided therefor can basically comprise the following method steps.

[0023] First, an assembly unit is created in the manufacturer's factory, the assembly unit comprising a personnel transport device or a section of a personnel transport device. In addition, the assembly unit also comprises a protection device, the protection device having a support with a hinge.

[0024] In a further method step, the at least one protection device is connected to the personnel transport device, the clamping region of the protection device being firmly clamped in the clamping device of the personnel transport device. Then, the at least one protection device is installed to a transport position before being transported from the manufacturer's factory to the building structure. In other words, the protection device can be said to be folded up and transported lying flat on the personnel transport device.

[0025] In a further step, the assembly unit is transported to the building structure and used in the support site provided therefor. After fitting in, the protection device can be pivoted into the assembly position and fixed in this position. Of course, it is also possible to pivot the protection device into the assembly position before fitting in the personnel transport device.

[0026] The above method can be supplemented with further steps. For example, the method may include the step of continuously replacing at least one protective device with the guardrail panel of the personnel transport equipment. This is done by removing the clamping area of ​​at least one support member of the protective device from the clamping device after releasing at least one clamping device of the personnel transport equipment, and then securely clamping at least one guardrail member into the clamping device in place of the removed clamping area. Assembly personnel should use personal safety equipment to secure themselves to adjacent protective devices (before or after) to avoid possible falls. This ensures a complete safety chain.

[0027] The preceding description also points out that, similar to the arrangement of the guardrail panels, it is preferable to securely clamp multiple protective devices arranged side-by-side along the longitudinal direction into the guardrail clamps, rather than simply having a single rigid railing extending along the entire length of the personnel transport equipment on each side. The shorter, side-by-side protective devices are also easier to operate, thereby further reducing the risk of accidents. Attached Figure Description

[0037] Figure 1 A simplified view of a personnel transport device 1 with a support structure 11 designed as a frame structure is shown. The personnel transport device 1, designed as an escalator, connects the lower plane E1 and the upper plane E2 of a building. A rotating step belt 9 is arranged in the support structure 11, deflecting in both the upper plane E2 and the lower plane E1, thus having a forward section and a return section. For clarity, the return section, frame, guide rails, track modules, and drive unit are not shown. The personnel transport device 1 also has two guardrails 15 extending along each longitudinal side of the step belt 9. Figure 1 Only the guardrails 15 arranged in the foreground of the observation plane are visible. Handrails 17 are arranged around each guardrail 15, with the return sections of the handrails arranged in guardrail bases 13, which connect the guardrails 15 to the support structure 11. Each guardrail 15 includes multiple (preferably transparent) guardrail panels 31, 32, 33, 35, and 36, wherein the uppermost guardrail panels 31 and 32 and the lowermost guardrail panels 35 and 36 have specific shapes. The middle guardrail panel 33 is typically a rectangular plate.

[0038] Figure 2 The basis for showing the line AA is shown. Figure 1 A cross-section of the personnel transport equipment 1. In this cross-section, both the forward and return sections of the ladder belt 9 are visible. The ladder belt 9 is guided on guide rails 19 within the support structure 11. When the personnel transport equipment 1 is installed as intended, guardrails 15 and guardrail bases 13 are respectively arranged on the left and right sides of the forward section arranged on the upper part of the ladder belt 9. Inside the guardrail base 13 is a clamping device 21 covered by lining plates 5 and 7, which serves as a clamping and receiving part for each guardrail panel 31, 32, 33, 35, and 36 (see also...). Figure 1 Here, the guardrail panels 31, 32, 33, 35, and 36 are fixedly clamped in position within at least one of the clamping devices 21 at their lower end panel clamping areas 34. The clamping devices 21 are arranged on the support structure 11 in a longitudinal direction within the guardrail base 13. Furthermore, the return section of the handrail 17 is also guided within the guardrail base 13.

[0039] Figure 3A three-dimensional view of the protective device 41 in the first embodiment is shown, which can be securely clamped in the clamping device 21 of the personnel transport equipment 1. In this embodiment, the protective device 41 has three supports 43. The three supports 43 are securely connected to each other by three blocking devices 45 to form a rigid railing. Here, the blocking devices 45 may be designed differently, but have essentially the same characteristics. The blocking devices 45 block the gaps between the supports 43, thereby preventing assembly personnel from falling from the personnel transport equipment 1 through the gaps between the supports 43.

[0040] Foot areas 47 are designed at the lower end of the support member 43. Figure 3 In this embodiment, the foot region 47 includes a hinge 51 arranged between the end of the support member 43 and a clamping region 49 formed in the foot region 47. The clamping region 49 is the area of ​​the foot region 47 that is securely clamped in the clamping device 21. As indicated by the double arrow 53, the support member 43 further includes a portion of a protective device 41 located above the hinge 51 that can pivot relative to the clamping device 21. As described below, the protective device 41 must be secured in the indicated position, hereinafter referred to as the "assembly position," during assembly operations so that the protective device does not pivot accidentally when the assembly personnel are performing assembly operations on the personnel transport equipment 1.

[0041] In order to avoid the need for the universal protective device 41 to be specifically coordinated with the distance P of the clamping device 21 arranged on the support structure 11, the clamping areas 49 of multiple supports 43 can be connected to each other, as shown by the double-dotted line 91. The continuously constructed clamping areas 49 also have the additional function of a barrier device.

[0042] The barrier device 45 can be a slat, rod, pipe, etc., suitable for connecting the support members 43 to each other. Preferably, the barrier device 45, mounted on the upper end of the support member 43, is designed as a rod and has a cross-section with rounded longitudinal edges. Advantageously, for example, a personal safety device 37 can be hung there and easily moved along the barrier device 45.

[0043] The rod-shaped barrier 45, used for suspending the personal safety device 37, can be positioned above or below the hinge 51. Installation below the hinge 51 offers advantages in terms of the dual function of connecting multiple supports 43 in a common clamping area 49: compared to mounting the personal safety device 37 on the barrier 45 positioned above the hinge 51, the forces and bending moments occurring on the supports 43 in the event of a fall. Another equally important advantage of suspending the personal safety device 37 below the hinge 51 is that it can be used or suspended even when the protective device 41 (in the transport position) is folded. However, the position of the rod-shaped barrier 45 can be achieved at any height of the protective device 41 and depends on the construction of the clamping device 21 and the support structure 11 of the personnel transport equipment 1.

[0044] Figure 4 Show Figure 3 The enlarged 3D view of detail B shows that the foot area 47 shown here does not have hinge 51. Hinge 51 is only shown here with a dashed line to indicate that it can also be used here. When the protective device 41 is only to be fitted into the clamping device 21 of the personnel transport equipment 1 in the building 5, for example when replacing the guardrail 15 or when modernizing the entire personnel transport equipment 1, the support member 43 of the foot area 47 with this rigid design is preferably used.

[0045] To securely clamp the clamping region 49, the clamping device 21 has a clamping jaw 29 with a wedge-shaped groove 27, as well as a wedge element 25 and a tensioning element 23. Here, the clamping region 49 is introduced into the wedge-shaped groove 27, and then the wedge element 25 is tightened together with the clamping region 49 by the tensioning element 23 in the wedge-shaped groove 27. For effective and reliable clamping, the clamping region 49 has two parallel clamping surfaces 93 with a thickness gap S matching the wedge-shaped groove 27 and the wedge element 25. The thickness gap is preferably equivalent to the thickness of the material to be securely clamped after the guardrail panels 31, 32, 33, 35, and 36. If the thickness gap S is too small, additional inserts (not shown) can be added to the clamping region if necessary.

[0046] Similar to Figure 2 As shown, Figure 5A cross section through the personnel carrier 1 is shown, in which instead of the guard rail 15 a protection device 41 with a foot region 47 is fitted in the clamping device 21 of the personnel carrier 1. Thereby, a fitting unit 101 is formed. The protection device 42 can be arranged to be arranged lying horizontally for an upcoming transport or to be arranged on the upper side of the personnel carrier 1 in a transport position 61. As shown by the dashed line, the protection device 41 can be brought into or pivoted into a fitting position 63 due to its hinge 51, the support 43 of the protection device 41 extending essentially in vertical direction in the fitting position 63.

[0047] In order to enable the protection device 41 to be fixed in the fitting position 63, various possibilities for reliably locking the hinge 51 exist, as Figure 6 to Figure 8 are exemplary shown in the figures.

[0048] Figure 6 The protection device 41, designed as a rigid barrier, is shown, in particular its support 43. The hinge 51 is constructed in the foot region 47 of the protection device. The hinge 51 essentially comprises a hinge bearing 55, which is firmly connected with the clamping region 49, and a hinge bracket 57, which is firmly connected with the support 43. The hinge bracket 57 is pivotably supported on the hinge bearing 55 by means of a hinge shaft 59. The firm connection of the hinge bearing 55 with the clamping region 49 is achieved by means of a threaded section 65. A fixing nut 67 is rotatably supported on this threaded section 65. In order to at least in the fitting position 63 prevent pivoting of the hinge 51, the fixing nut 67 can be tightened or jammed towards a pivotable locking face 69 of the hinge bracket 57 relative to the fixing nut 67. The threaded section 65, the fixing nut 67 and the locking face 69 thus together form a locking device 77.

[0049] Figure 7 Another possible design of the locking device 77 with a locking element 71 is shown, which is arranged in the foot region 47 of the protection device 41. In order to lock the hinge 51, the locking element 71 can be brought into a through-going portion 73 provided for this purpose, which is constructed on the support 43 and the clamping region 49. Thereby, the support 43 and the clamping region 49 are rigidly fixed to one another. In a specific embodiment, the support 43 and the clamping region 49 for this purpose have a leg or a flange 75, into which two through-going portions 73 are constructed. For example, a simple threaded connection can be used as locking element 71. Of course, also ball locks, bolts, cotter pins, etc. can be used for this purpose.

[0050] Figure 8Another possible design of the foot region 47 of the protection device 41 with a detent mechanism 81 is shown. In this design, the support 43 is also connected with the clamping region 49 by means of a hinge 51, which is here firmly clamped in the schematically shown clamping device 21. The detent mechanism 81 mainly has a spring element 83 and a detent element 85. In the shown assembled position, the detent element 85 is in detent engagement with a detent edge 87. This detent edge 87 is configured in the clamping region 49. The detent mechanism 81 and the detent edge 87 together form the locking device 77. Figure 8 In the present embodiment, the detent element 85 is pivotably supported on the support 43 and is loaded there by the spring element 83. In the shown assembled position, the detent element 85 is in detent engagement with a detent edge 87. This detent edge 87 is configured in the clamping region 49. The detent mechanism 81 and the detent edge 87 together form the locking device 77.

[0051] Furthermore, Figure 8 a rigid barrier (which is formed by the support 43 and the barrier device 45, which are not detachably connected from one another) is not shown, as in the previous embodiments of Figure 6 and Figure 7 but a barrier is shown, which is formed by components of the protection device 41, which can be assembled. Here the support 43 has a receptacle 89, which serves as a holder for the barrier device 45. Such a protection device 41 is arranged on the personnel conveyor 1 in the following way. First, the support 43 is firmly clamped into the existing clamping device 21 of the personnel conveyor 1. After the personnel conveyor 1 is fitted into the support site 3 of the building structure 5 provided for this purpose, the support 43 can be pivoted from the transport position 61 to the assembled position 63 and detented. The barrier device 45 is then pushed through the receptacle 89, so that the barrier device 45 is held by at least two supports 43. If necessary, the barrier device 45 can be fixed in the receptacle 89 or on the support 43 by suitable fastening elements, such as ball lock pins, split pins or screws.

[0052] Although Figure 1 to Figure 8 different aspects of the invention are shown on the basis of a personnel conveyor 1 designed as an escalator, which is used to connect vertically spaced floors E1, E2, it is clear that the devices and corresponding method steps introduced can also be used for inclined moving walks or moving walks arranged on a horizontal plane.

[0053] Finally, it should be noted that the terms "comprising", "including", etc. do not exclude other elements or steps, and the terms "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps which have been described with reference to one or more of the above embodiments can also be used in combination with other features or steps of other embodiments. Reference signs in the claims should not be construed as limiting the scope of the claims.
