    description
    Gap bridging and method for operating a
    gap filling
    Technical field
    The invention relates to a gap bridging for a
    Rail vehicle for bridging the gap between a passenger compartment floor and a platform and a method for operating this gap bridging.
    State of the art
    Gap bridges are used in modern rail vehicles to enable passengers to get in and out comfortably and in particular to minimize the risk posed by the gap between the floor of the passenger compartment and the platform. In typical subway lines, this gap has a width of approx. 100 mm, but can also be up to 300 mm, for example, on platforms on a curved track. This variance of the gap dimensions represents a special one
    This is a source of danger, since the passengers would have to watch out for the current platform gap each time they get on or off, which is often not possible when there is a high volume of passengers. To bridge this platform gap, gap bridges can be used, which usually comprise a slidably mounted plate, which can be pushed out of the vehicle with the aid of power. For larger gap widths, this plate and its storage are to be made very solid, so that the installation space requirement increases and thus such gap bridges are only very complicated and underneath
    Impairment of the car body can be provided in the door area. This problem can be partially solved with so-called folding / sliding steps, since in such a case a pivoted lever supports the plate from below and thus significantly reduces the forces on the mounting of the plate. Such folding / sliding steps therefore require less installation space and can be used in the boarding area of a passenger rail vehicle without changes to the body structure, with the conventional floor structure simply being removed at the installation position of this gap bridging and being replaced by the gap bridging. However, the kinematics of these gap bridges in the form of a folding / sliding step means that when the plate is extended, it lowers on its edge on the platform side, thus creating a step to the platform. In addition, a wide extended plate has a steep slope towards the inside of the car. These properties make gap bridging in the form of a folding / sliding step unsuitable for larger platform gaps.
    Presentation of the invention
    The invention is therefore based on the object
    Specify gap bridging in the form of a folding / sliding step and a method for operating this gap bridging, which is suitable for larger platform gaps and in which, in particular, the height difference between a platform and the edge of the step plate on the platform side is minimized with large extension distances.
    The object is achieved by a gap bridging with the features of claim 1 and a method according to claim 8. Advantageous refinements are the subject of subordinate claims.
    According to the basic idea of the invention
    Gap bridging for a rail vehicle to bridge the gap between a passenger compartment floor and a platform, which comprises a horizontally slidable step plate and a pivot arm connected to the tread plate by means of a joint, the pivot arm being equipped with a vertically displaceable pivot joint at its end facing away from the joint is.
    This provides the advantage of being able to build a gap bridging in the form of a folding / sliding step, which can produce entry levels of the step plate that are flexibly adapted to the particular structural conditions of platforms. In particular, a certain height of the platform-side edge of the step plate, which is optimized for this platform, can be set for each platform that is approached, with the step plate in each case having a different extension width, so that the passenger finds the same comfort on each platform. Furthermore, with the objective gap bridging, a different extension distance can be realized for each exit over the length of a train or over the length of a vehicle, the height of the platform-side edge of the step plate always having the same difference in level to the edge of the platform. This is particularly important for platforms along track arches.
    According to the invention, the kinematics of a gap bridging is designed in the form of a folding / sliding step so that the lower articulation point of the swivel arm can be displaced in height in relation to the track level or the platform. In this way, a lowering of the edge of the platform on the platform side can be prevented when the step plate is extended further, since the lower articulation point can be shifted upwards. The movement of the tread plate is independent of the displacement of the lower articulation point and both movements can be carried out essentially independently of one another. At most, the mobility of the lower articulation point with small extension distances is the
    Footplate limited by the risk of collision of the footplate with cladding components, for example a cover plate.
    The pivot point (pivot point, joint) of the swivel arm is slidably mounted along a vertical axis in a certain length section. The exact dimensioning of the required length section is based on the given geometry of a gap bridging and the extension width of the step plate and the required predeterminable height range of the edge of the step plate on the platform side.
    This is advantageously adjusted
    Articulation point by means of an electric power drive, for example by means of a threaded spindle.
    In a further development of the invention, it is proposed to apply a restoring force to the swivel arm, preferably by means of a spring element which attempts to move the swivel arm into its rest position (retracted tread plate). This restoring force causes one
    Supporting the return of the step plate and the swivel arm to their retracted rest position.
    According to the invention, the step plate is horizontally slidably mounted, and is preferably equipped with a power drive, by means of which it can be moved between a rest position (retracted) and any number of different extended positions. In this way, the optimal extension distance can be provided for different structural conditions within a railway line. The tread plate is typically extended until either the maximum extension distance is reached or the tread plate collides with the platform, the power drive being switched off as a result.
    The tread plate is mounted in a sliding guide, the end of the tread plate on the car side being guided and the end on the platform side being freely movable so that it is supported by the swivel arm. The swivel arm transfers most of the load on the tread plate
    Weight forces, the sliding guide can thus be made very compact.
    The advantage of being able to build a gap bridging according to the invention so flat that it has the same thickness as a surrounding floor structure can be achieved in this way. Thus, a gap bridging can be installed without changes to the body structure, in particular the side members on the side of the door sill.
    It is advantageous to equip the tread plate with a sensor for determining the distance to a platform or for determining whether the platform has been touched.
    This sensor can be based on the capacitive measuring principle or optically detect the distance (infrared sensor) or mechanically actuate an electrical contact when touched. With this sensor, the horizontal distance of the platform-side edge of the step plate can be determined, or additionally or alternatively the vertical height difference of the platform-side edge of the step plate to the edge of the platform can be determined.
    A control device is advantageously to be provided, which includes devices for operating the power drives for the tread plate and the height shift of the pivot point of the pivoting lever, for example corresponding power and protective electronics. Furthermore, it is
    To equip control device for the reception of signals from a sensor. This signal is used to transmit a signal which is proportional to the distance between the platform-side edge of the step plate and the platform to the control device. A computing unit contained in the control device determines from the information supplied to it a specific combination of the extension of the tread plate and the position (displacement) of the lower linkage of the swivel arm. The information supplied to the control device can include: signal received by the sensor, describing the distance from the platform-side edge of the step plate to a platform, or the height difference to the platform, the position of the train in the route network (current stop), position of the carriage in the train set , Position of the exit in a wagon, loading condition of the wagon.
    In this case, a data memory can be provided in the control device, in which the combination of extension width of the step plate and position (displacement) of the lower linkage of the swivel arm to be used for each stop is stored. In particular, it is advisable to also store the position of the entry in the train set associated with the gap bridging in the data memory and to use it to determine the respective combination of the extension width of the step plate and displacement of the lower linkage. In this way, use cases of stops arranged in curves can be taken into account, in which different extension widths of the gap bridges at entrances near the end faces compared to entrances in the middle of the car are required.
    These data can be stored unchangeably in the data memory or can be determined continuously during processing while the sensor signal is being processed.
    The last embodiment creates a continuously self-learning system, which increases the precision of the actuation of the tread plate and the swivel arm and thus increases the comfort of the passengers. Furthermore, the advantage of being able to continue operating the gap bridging even in the event of a sensor failure can be achieved, with at most a slightly reduced precision of the
    Positioning of the step plate occurs. The control device uses the values for the extension distance and vertical positioning of the swivel joint stored in the data memory and operates the gap bridging in a controlled, unregulated operating method.
    A data connection to a train control system is preferably to be provided, via which the control device receives information about the position of the train in the route network, the current loading condition of the wagon as well as the necessary exit and entry commands as well as a status feedback from
    Gap bridging can be transmitted to the train control. It is particularly important that the
    Sequence of actuation of gap bridging - door opening can run correctly and the vehicle cannot start, especially when the gap bridging is extended.
    The data connection to a train control system can take place by means of certain control signals or can be implemented as a transmission of data telegrams, for example in the manner of the Internet protocol.
    In a further development of the invention, a manually operable emergency drive is to be provided, by means of which the driving personnel can bring a gap bridging according to the invention into its retracted rest position if the drives or the control device should fail. In this way, the vehicle can continue to operate, possibly with a locked entry point.
    In a further development of the invention, it is advisable to equip the gap bridging with a device for preventing the entry of dirt (wipers). A cover plate is to be provided above the tread plate in the area of the passenger compartment floor, this cover plate being provided with a scraper on its edge on the platform side. This cover plate has essentially the same height level as the vehicle floor surrounding it, so that no level differences due to the gap bridging, in particular no steps, are required inside the car. A scraper is to be arranged on the edge of this cover plate on the platform side, which closes or significantly reduces the gap between the cover plate and the step plate when the tread plate is retracted, so that foreign bodies do not penetrate, or only up to a certain size, into the space under the cover plate can.
    It is particularly advantageous if the scraper touches the tread plate and the contact force is at least increased by an elastic element.
    For example, rubber lips, brushes or metal strips with friction-reducing pads can be used as wipers.
    Brief description of the drawings
    The following are examples:
    Fig. 1 gap bridging retracted, prior art.
    Fig.2 extended gap bridging, prior art.
    Fig. 3 Retracted gap bridging.
    Fig. 4 Gap bridging extended.
    Fig. 5 gap bridging, view from above.
    Implementation of the invention
    1 shows an example and schematically one
    Gap bridging according to the prior art in the retracted position. It is a cross section through one
    Passenger rail vehicle shown in the area of an exit, a gap bridging 1 ′ being provided according to the prior art. The passenger rail vehicle is shown in the form of its body 12, comprising a side member and a floor structure made up of a floor plate 13 and a cover plate 2. Between the vehicle and a platform 3 is a gap 4, which by the
    Gap bridging device 1 'is to be bridged. This comprises a step plate 6 according to the prior art, which is mounted horizontally displaceably at its end on the side of the car body by means of a sliding bearing 8, a slide 9 being arranged on the step plate 6. The slide 9 enables a lateral displacement of the tread plate 6 with respect to the sliding bearing 8 and a pivoting of the tread plate 6 about a longitudinal axis of the car body 12. The tread plate 6 is supported from below by a swivel arm 5 according to the prior art, which is about an axis of rotation 7 is pivotally mounted. At the end facing away from the axis of rotation 7, the swivel arm 5 is connected to the step plate 6 via a joint 10, this joint 10 is arranged in a stationary manner on the step plate 6. The swivel arm 5 is acted upon by a restoring force which attempts to pull it back into its rest position. For this purpose, a spring 11 is shown as an example in FIG. 1. Fig. 1 shows the retracted state of the gap bridging 1 'as it is used in particular while driving. A power drive acting on the tread plate 6 is not shown to simplify the illustration.
    2 shows an example and schematically one
    Gap bridging according to the prior art in the extended position. The gap bridging 1 ′ from FIG. 1 is shown, the tread plate 6 being pushed into its further extended position and the gap 4 being thus bridged. In this position is a big one
    Level difference between the platform 3 and the platform-side end of the step plate 6 and the inclination of the step plate 6 is particularly large.
    3 shows an example and schematically one
    Gap bridging in the retracted position. It is a gap bridging 1 according to the invention in a cross section through a passenger rail vehicle, very similar to that in FIG
    Fig.1 shown. The construction of the passenger rail vehicle is identical to the exemplary embodiment shown in FIGS. 1 and 2, but the gap bridging 1 differs in that the swivel arm 5 is connected to the car body 12 in a rotatable and vertically displaceable manner at its lower end by means of a displaceable swivel joint 14. As a result, the axis of rotation about which the swivel arm 5 is rotatably mounted is in its vertical position relative to the
    Body can be moved in a certain area. An extension drive 19 is provided for the movement of the tread plate 6, the displacement of the displaceable
    Swivel joint 14 takes place by means of a vertical drive 20.
    The drives 19, 20 are constructed as electric motors and are controlled by a control device 23. At the
    Step plate 6 has a sensor 21 arranged on its platform-side edge, which detects the relative position of the platform-side edge of step plate 6 to platform 3 and transmits a corresponding signal to control device 23. Furthermore, the control device 23 comprises interfaces for data communication with a door control 24 and a train control 25. In the exemplary embodiment shown, the gap bridging 1 is with a wiper 15, which is arranged on the platform-side edge of the cover plate 2 and can be pivoted with the cover plate 2 by means of a joint 16 connected is equipped. The joint 16 can be equipped with an elastic device which increases the pressing force of the scraper 15 on the tread plate 6. An edge of the scraper 15 touches the tread plate 6, as a result of which dirt adhering to the tread plate 6 is removed from the scraper 15 and thus cannot penetrate into the space below the cover plate 2. In this way, excessive contamination of the sliding bearing 8 and associated drive components can be prevented.
    4 shows an example and schematically one
    Gap bridging in the extended position. It is the
    Gap bridging 1 shown in Figure 3, the
    Step plate 6 is in the extended position and thus bridges the gap 4. The displaceable swivel joint 14 is displaced upwards by a certain vertical displacement 22 by means of the vertical drive 20, so that the edge of the step plate 6 on the platform side has only a minimal level difference to the platform 3.
    5 shows an example of and schematically a view of
    On top of a gap bridging 1 in its installation situation in a car body 12. In this view, sections of the car body 12 through two door pillars and parts of the outer wall are visible. The tread plate 6 is partially extended
    Position, its surface is divided into areas with non-slip surface or covering 18 and sliding surfaces 17, the sliding surfaces 17 occupying a significantly smaller proportion of the total surface. The
    Sliding surfaces 17 are advantageously arranged deeper than the surfaces 18 with an anti-slip covering, so that they cannot be entered directly. As shown in FIG. 6, a stripper 15 is connected to the cover plate 2 in an articulated manner.
