Definitions
- the invention relates to a protective device for protecting assembly personnel during assembly work on a passenger transport system designed as an escalator or moving walk, and an assembly unit with a corresponding protective device and a method with assembly steps for erecting and dismantling the protective device.
- Passenger transport systems which are designed as escalators or moving walks, are used in buildings in the public sector such as train stations, underground stations, airports, shopping malls, cultural centers and the like. Escalators or moving walks have a load-bearing structure that is referred to as a supporting structure. Most of the time, this supporting structure is a framework construction, which is manufactured by the manufacturer as a whole unit or subdivided into supporting structure modules. The supporting structure or its supporting structure modules, or truss modules, are installed in a building, with the supporting structure connecting two floors of the building, for example.
- the movable components of the escalator or moving walk are arranged in this support structure, for example a step belt or a pallet belt, circulating handrail belts, deflection axles, a drive shaft and parts of the drive motor and transmission and the like. Furthermore, fixed components such as balustrades, comb plates, bearing points, raceways and guide rails, a controller, monitoring systems, safety systems and the like are also firmly connected to the structure. Normally, escalators and moving walks are completely assembled in the manufacturer's works and, as a whole or divided into sections thanks to the supporting structure modules, are transported from the manufacturer's works to the building and used there in the support points provided for this purpose.
- balustrade clamps permanently mounted on the structure, in which the balustrade components, in particular balustrade panels made of glass, can be permanently clamped. Since the balustrades have many components that are visible to users, it is a particular advantage if the balustrades (including those with sheet metal panels) are only installed during the last assembly steps on the construction site.
- WO 2019/185573 A1 proposes a protective device designed as a maintenance railing, which can be fastened to the upper chord of the structure by means of clamping devices arranged on the supports. This protective device is very easy to install or remove.
- WO 2021/175708 A1 also discloses a corresponding maintenance railing, which cannot be clamped to parts of the support structure, but rather in the balustrade clamps of the passenger transport system. When installing the balustrade panels, the protection is then dismantled support by support and the gaps created are immediately fitted with balustrade panels.
- the object of the present invention is to provide a protective device which prevents these negligence and thus prevents accidents.
- a protective device for protecting assembly personnel during assembly work on a passenger transport system designed as an escalator or moving walk.
- the protective device comprises at least one shut-off device and at least one support, which are fixed to one another or can be connected to one another by suitable connection points.
- the shut-off device extends transversely to at least during the assembly work Support and in the longitudinal extent of the passenger transport system, wherein the support has at one of its ends a fastening area which is designed for fastening to a supporting structure of the passenger transport system.
- the protective device has at least one sensor module and a signal connection unit, the signal connection unit being set up to exchange data with the at least one sensor module and with a data transmission module of the passenger transport system.
- the sensor module is arranged in the fastening area of at least one support, with this sensor module being able to record data about a fastening state of the fastening area and transmit this data to the data transmission module of the passenger transport system via the signal connection unit.
- one support, several supports or all supports of the protective device can have a sensor module in their fastening area.
- the sensor module detects whether or not the protective device is attached to the structure and transmits corresponding data to a data transmission module of the passenger transport system via the signal connection unit.
- the data transmission module can forward this data to a service and assembly center, for example, which coordinates and monitors the assembly work. Since the protective device has to be erected at the beginning of the assembly work, a supervisor in the service and assembly center can call up the current data on the attachment status of the protective device and intervene if the protective device has not been installed. As described in more detail below, installation instructions to installation personnel may also be withheld until the protective device has been properly installed. It is also conceivable that assembly tools or parts of the control of the passenger transport system can be automatically locked or unlocked depending on the data reflecting the state of attachment.
- the sensor module includes at least one sensor element from the group consisting of a force measurement sensor, a bipolar switch, a proximity sensor, an optical sensor and the like, and the sensor element is arranged in the fastening area of the support in such a way that it can optimally detect a fastening or a missing fastening of the fastening area.
- the sensor element is a force measuring sensor, for example a strain gauge, it must be arranged in the fastening area in such a way that it detects expansion or compression of the fastening area as a result of a force applied by fastening means by means of a change in electrical resistance. If necessary, the fastening area must be optimized and designed for the sensor element used.
- the sensor element must be supplied with electrical energy so that a physical change in status in the fastening area can be detected at all.
- the sensor module can include, for example, an accumulator, a capacitor and the like, which can be charged with electrical energy and emit it again.
- a data transmission means is required, which converts the mostly analog signal of the sensor element into electronically processable data and forwards this to the signal connection unit.
- Active or passive systems such as Bluetooth, HF transmission units, a passive or active RFID tag (RFID chip with a ring antenna) and the like can be used as data transmission means.
- wireless, passive data transmission means are preferable for practical reasons, wired systems can of course also be provided, in which case the data transmission means can be a simple plug-in connection or a network node.
- passive RFID tags whose chip is coupled with a strain gauge as a sensor element, for example, is particularly advantageous.
- the changing resistance value of the strain gauge as a result of a force acting on the support provided with the sensor module changes the output response or the output data of the RFID tag.
- Such a sensor module does not require its own energy source either, since the required electrical energy is fed in inductively via the antenna when reading out.
- Such a sensor module is described, for example, in the report “Force Sensor System for Structural Health Monitoring using Passive RFID Tags for Structural Health Monitoring” by authors Yusuke Ikemoto, Shingo Suzuki, Hiroyuki Okamoto, Hiroki Murakami, Xin Lin, Hideo Itoh, and Hajime Asama [https://ieeexplore.ieee.org/document/4681264] from 2008.
- the signal connection unit of the protective device can be an RFID reader, which also has a signal transmission module.
- the signal transmission module is used to transmit the data read out from the sensor module, possibly processed, to the data transmission module of the passenger transport system, which is described in more detail below.
- the fastening area of the support is designed as a clamping area.
- the clamping area is modeled on a panel clamping area of a balustrade panel of the passenger transport system and is intended to be fastened in a clamping device permanently mounted on the support structure of the passenger transport system.
- clamping devices that are already present on the structure are used.
- the sensor module can detect whether the clamping area is fastened in a clamping device or not.
- the term “simulated” here means that the fastening area, like the panel clamping area, is designed in such a way that it fits into a loosened clamping device and is securely clamped by the clamping device after it has been tightened.
- the fastening area of the support is designed as a tensioning device.
- This clamping device is suitable for attachment to the supporting structure of a passenger transport system and is tailored to the corresponding components of the supporting structure, for example to the cross-section of its upper chord steel profile.
- the clamping device has a clamping cheek and at least one clamping claw that can be braced against the clamping cheek.
- the sensor module is arranged in the clamping claw and/or in the clamping jaw, so that the sensor module can detect whether a region of the support structure is fastened between the clamping cheek and the clamping claw or not.
- at least two supports are firmly connected to at least one barrier device and thereby form a rigid railing. This allows them to be assembled and disassembled more easily on the passenger transport system than if the supports and the locking device are separate components of the protective device.
- the at least one support has a receptacle in which the shut-off device can be arranged so as to protrude.
- This configuration can have the disadvantage that the fitters install the supports but not the shut-off devices.
- a sensor module is arranged in the receptacle, which can record data about an arrangement of the shut-off device or its absence in the receptacle. This data is also transmitted to the data transmission module of the passenger transport system via the signal connection unit.
- the support or the supports have a hinge arranged between the fastening area and the shut-off device or its receptacle.
- the support can be pivoted between a transport position and an assembly position.
- a sensor module is also arranged in the area of the hinge, which detects data about a position of the hinge and transmits this data via the signal connection unit to the data transmission module of the passenger transport system.
- the hinged support can be pivoted between a transport position and an assembly position.
- This configuration makes it possible for the protective device to be fastened to the supporting structure in the manufacturer's factory. Then the supports attached to the supporting structure and, if necessary the shut-off device connected to them is also pivoted into the transport position.
- the transport position is that position in which the support extends essentially horizontally and in the transverse direction to the longitudinal extension of the passenger transport system.
- the transport position allows the overall height of the passenger transport system to be kept as low as possible for its transport between the manufacturer's plant and the support points provided for it in the building, despite the protective device already being installed.
- the protective device or its supports can be pivoted into the assembly position.
- the assembly position is essentially to be understood as a vertical towering of the supports.
- the protective device leaves the manufacturer in a lying position relative to the personnel transport position and can be unfolded and fixed in a standing position on the construction site.
- the support can have a blocking device.
- This blocking device is designed to block pivoting of the hinge at least in the assembly position.
- the position of the blocking device can also be detected with a sensor module.
- the shut-off device is designed such that personal protective equipment can be attached to it.
- the personal protective equipment includes a harness, which usually has two short pieces of rope (slings) with snap hooks.
- the fitter wears the harness on his body over his clothes and at least one of the snap hooks is attached to the locking device or the support. It is usually stipulated that both snap hooks must be attached. If the fitter falls, his fall height is limited by the rope length of the slings. Their ability to stretch is also specified in the relevant standards, so that the fall is cushioned.
- At least one sensor module can be arranged in the support in such a way that a fall caused by a fall and onto the protective device acting voltage peak can be detected by the sensor module and corresponding data can be transmitted via the signal connection unit to the data transmission module of the passenger transport system.
- the aforementioned sensor module does not necessarily have to be independent of the sensor module that monitors the fastening area.
- the sensor module of the attachment area can also be arranged in such a way that it can detect such voltage spikes.
- a people-transport system and at least one protective device together form an assembly arrangement that also includes a user interaction module and an assembly script.
- the subsequent assembly process can be carried out with this assembly arrangement, with the assembly personnel being forced to comply with the prescribed safety measures by the structured guidance of the assembly script to be processed.
- the procedure for carrying out assembly work on an assembly arrangement comprises the steps:
- the assembly script can require that the assembly personnel use personal protective equipment to secure themselves to the supports and/or to the shut-off device.
- data of a voltage peak detected by a sensor module can be transmitted to the data transmission module of the passenger transport system via the signal connection unit and permanently stored in a storage medium. This makes it possible to check whether the fitter was exposed to excessive forces during the fall and whether the safety concept (e.g. the length of the straps of the personal protective equipment or the number and/or position of the available fastening points) needs to be adjusted.
- the installation script may include the following additional steps:
- the at least one protective device is successively replaced by balustrade panels of the passenger transport system. This is done in that, after at least one of the clamping devices of the passenger transport system has been released, the support of the protective device is removed and, instead of the support, a balustrade panel, for example, is clamped in the clamping device becomes.
- the assembly personnel should use their personal safety equipment to secure themselves at the adjacent protective device (before or after) in order to avoid a possible fall. This ensures a complete safety chain.
- FIG. 1 shows a simplified view of an assembly arrangement with a protective device in a first embodiment variant and with a passenger transport system in the central part of which no balustrade has yet been constructed;
- FIG. 2 a three-dimensional, enlarged view of detail A indicated in FIG. 1, the fastening area shown having a hinge and a latching mechanism;
- Figure 3 in a three-dimensional view of a second possible embodiment variant of the protective device.
- FIG. 1 shows a simplified view of an assembly arrangement 1 with a passenger transport system 11 and a protective device 51.
- the passenger transport system 11 connects a lower level El with an upper level E2 of a building 5.
- the passenger transport system 11 designed as an escalator has a framework construction running structure 33 on.
- a circumferential step band 13 is arranged in the support structure 33, which is deflected in the upper level E2 and in the lower level E1 and thus has a leading section and a returning section.
- the receding section was not shown, nor were frames, guide rails, rail blocks and a drive unit shown.
- the passenger transport system 11 also has two balustrades 15 which extend along each longitudinal side of the step band 13, only the balustrade 15 arranged in the viewing plane in the foreground being visible in FIG.
- a handrail 17 is arranged circumferentially on each balustrade 15 , the returning section of which is arranged in a balustrade base 19 .
- the balustrade base 19 also connects the balustrade 15 to the deck 33.
- the balustrade 15 has a plurality of (possibly transparent) balustrade panels 21, 23, 25, 27, 29, with the top balustrade panels 25, 27 and the bottom balustrade panels 21, 23 being specially shaped are.
- the center balustrade panels 29 are generally rectangular panels.
- a guide profile 31 for guiding the handrail 17 is arranged on at least one edge area of the balustrade panels 21, 23, 25, 27, 29 in each case.
- the passenger transport system 11 has not yet been completely installed.
- the central balustrade panels 29 still have to be assembled.
- the handrail 17 sags in the central area of the passenger transport system 11 down to the base 19 of the balustrade. If assembly personnel are in this central area and work, they must be secured against falling down to the side.
- the protective device 51 In order to protect the assembly personnel, the protective device 51 already mentioned is therefore temporarily installed in place of the missing balustrade panels 29 .
- the protective device 51 has a plurality of railings 53, each with three supports 55 and two blocking devices 57, the blocking devices 57 arranged parallel to one another connecting the supports 55 to one another.
- the supports 55 and shut-off devices 57 are profile tubes that are firmly welded together.
- the shut-off devices 57 extend at least when mounted on the personnel transport system 11 and thus during the Assembly work, transverse to the supports 55 and in the longitudinal extension of the passenger transport system 11. So that the supports 55 can be attached to the support structure 33 of the passenger transport system 11, they have a fastening area 59 at one of their ends. Due to the use of profile tubes, the shut-off device 57 is also suitable for personal protective equipment 121 to be attached to it, for example with its snap hook.
- the protective device 51 has at least one sensor module 61 and a signal connection unit 71, with the signal connection unit 71 being set up to communicate with the at least one sensor module 61 (double arrows 75 shown with a broken line) and with a data transmission module 93 (double arrow 75 shown with a dot-dash line) of the passenger transport system 11 to exchange data.
- the sensor module 61 is therefore arranged in the attachment area 59 of the support 55, with the sensor module 61 capturing data about an attachment state of the attachment area 59 and transmitting this data via the signal connection unit 71 to the data transmission module 93 of the passenger transport system 11.
- the assembly arrangement 1 also includes a user interaction module 95 and an assembly script 101.
- the user interaction module 95 can be a laptop, a tablet or a smartphone, for example.
- the assembly script 101 is retrieved from the storage medium 97 via a first data connection 77 (dash, double-dotted arrow) between the user interaction module 95 and the data transmission module 93 of the passenger transport system 11 and via a second data connection 79 (dash, three-dotted double arrow) between a storage medium 97 and the data transmission module 93.
- the storage medium 97 can be contained in the controller 91 of the passenger transport system 11 or in the data transmission module 93, for example. As shown, it can Storage medium 97 but also a data cloud 99 can be implemented, which is formed from a large number of interconnected servers.

After the implementation of each assembly step 103, ..., 115 its completion must be acknowledged by a user input 119 to the subsequent assembly step 103,. . . , 115 to call.
- the assembly script 101 requires the assembly of the supports 55 and blocking devices 57 as a first step 105.
- the attachment states of all attachment areas 59 provided with a sensor module 61 must be called up. Since the sensor module 61 is based on RFID technology, the fastening states are read out by means of the signal connection unit 71 designed as an RFID reader and this data is forwarded to the data transmission module 93 by means of an integrated signal transmission module 73 (dash-dotted double arrow 75). The data is transmitted from the data transmission module 93 to the user interaction module 95 (dash-double-dotted double arrow 77) and checked there.
- the next assembly step 109, . . . . . , 115 are displayed on the screen 96. If one of the attachment areas 59 is not attached, it will be displayed so that it can be properly attached.
- the assembly step 109 shown with a broken line represents a large number of assembly steps 109 in chronological order, which must be processed in order to get to an operational passenger transport system 11 .
- its completion is acknowledged by a user input 119 in order to call up the subsequent assembly step 109 .
- the assembly script 101 may also require assembly personnel to familiarize themselves with the personal protective equipment 121 secured to the supports 55 and/or to the locking device 57. Due to a suitable arrangement of the sensor modules 61 or by the arrangement of additional sensor modules 61 in the supports 55, voltage peaks caused by an excessive force acting on the shut-off device 57 or the supports 55 can be detected. During the implementation of assembly steps 103, . . . , 115 data of a voltage peak detected by a sensor module 61 can be transmitted via the signal connection unit 71 to the data transmission module 93 of the passenger transport system 11 and permanently stored in a storage medium 97 . This makes it possible to check whether the fitter was exposed to excessive forces in the event of a fall and whether the safety concept (e.g. the length of the safety rope or the available fastening points) needs to be adjusted.
- the safety concept e.g. the length of the safety rope or the available fastening points
- the assembly script 101 also provides for the disassembly of the protective device 51.
- this assembly step 111 is acknowledged, data about the state of attachment of the attachment areas 59 is retrieved via the data transmission module 93 and the signal connection unit 71 (assembly step 113).
- the acknowledgment by means of a user input 119 is permitted if the attachment area 59 is not attached and rejected if the attachment area 59 is attached. It can thereby be ensured that no part, for example no support 55 or clamping device (see FIG. 3) of a support 55 remains on the supporting structure 33 .
- Figure 2 shows a three-dimensional, enlarged view of detail A indicated in Figure 1, with the fastening area 59 shown here having a hinge 131 and a blocking device 133 which is designed to block pivoting of the hinge 131 at least in an assembly position M.
- Supports 55 with hinges 131 are preferably used when the protective device 51 is to be fastened in clamping devices 151 of the passenger transport system 11 in the factory.
- the supports 55 (with or without locking devices 57) can then be folded down into a transport position T and transported from the factory to the structure 5. After inserting the passenger transport system 11 in the building 5, the supports 55 must only be opened from the transport position T into the assembly position M and, if necessary, with the Shut-off devices 57 are provided.
- the fastening area 59 of the support 55 can be fastened in the clamping device 151 permanently mounted on the support structure 33 of the passenger transport system 11, it has a clamping area 135 which corresponds to a panel clamping area (not shown) of a balustrade panel 21, 23, 25, 27, 29 the passenger transport system 11 is modeled on.

- the RFID chip sends the measured resistance value R together with a value stored in the RFID chip 63 Resistance value RA back as a data packet via the ring antenna 65 to the signal processing unit 71.
- the resistance value RA stored in the RFID chip 63 represents the electrical resistance of the Bridge circuit 67 in the unloaded state.
- a slightly protruding plunger 137 which is arranged in the clamping area 135, transmits the clamping force of the tightened clamping device 151 to the zone of the sensor module 61 provided with the bridge circuit 67.
- the blocking device 133 is shown schematically to show its function. Since the sensor module 61 is arranged in the vicinity of the blocking device 133, the blocking device 133 and the position of the hinge 131 are also monitored with it. The blocking device 133 can only be actuated and act on a switch tongue 62 of the sensor module 61 when the support 55 is in the mounting position M. The switching position of the switching tongue 62 can be detected by the RFID chip 63 in that the switching tongue 62 is pressed onto a contact pin 64 by the blocking device 133 and a current pulse is used, for example, to check whether this circuit is closed. The sensor module 61 transmits corresponding data about the position of the hinge 131 via the signal connection unit 71 to the data transmission module 93 of the passenger transport system 11.
