Definitions
- the present invention relates to the field of platform bridging devices, both to the field of bridging devices fixed to the platform and to the field of bridging devices attached to a rail vehicle in the door area.
- the present invention relates to a device for substantially complete bridging of the gap between the car floor of a rail vehicle in the door area and the platform with a bridging plate for bridging the gap, wherein the bridging plate at least between a retracted position in which the gap is not bridged and the Bypass plate essentially not or only slightly over the front edge of the platform (in the case in which the bridging plate is slidably mounted on the platform) or the rail vehicle (in the case in which the bridging plate is slidably mounted on the rail vehicle) protrudes, and a extended position, wherein the gap is substantially completely bridged, is slidably mounted in a substantially linear horizontal direction.
- EP 0913307 describes a device which is intended to be fastened to the rail vehicle.
- a bridging plate in a substantially linear, at the bottom slightly down extending movement of a slot pulled out below the door area, this with the help of at least one, far below the range acheachsten lever.
- JP 2204160, JP 2212257 or JP 2005225310 have the disadvantage that they require a relatively large space below the area to be bridged.
- US 5,845,579 describes a lock-up device which is intended to be attached to a platform.
- it is proposed in one embodiment to store the bridging plate on linear bearings, and there is a relatively low overall height of the device.
- the problem with this design is the fact that when using linear bearings the lock plates blocked at the lowest load and also for the drive due to the large friction in the required heavy structures of the lock plate very powerful engines are required.
- it is necessary when using linear plain bearings due to the existing game to balance the shift in the direction of displacement very accurately.
- a bridging device for substantially complete bridging the gap between the car floor of a rail vehicle in the door area and the platform.
- the bridging plate is slidably mounted on at least two guide rails and the guide rails are formed as ball linear guides or as Rollenlinear Inserten.
- the essence of the invention is therefore to support the bridging plate to allow a low overall height of the entire bridging device in a pure linear sliding movement.
- the guide rails are on the one hand very smooth and allow a drive with a comparatively small sized engine, which allows a compact design.
- they are very directionally stable, so that it is not necessary to balance the process of displacement consuming, that is, it is possible, for example, only one drive on one side, or in the middle, if space permits.
- they are strong resilient, without that suffers the smooth mobility.
- the low friction in particular when realized in combination with a toothed belt, also allows an extremely high traversing speed of the bridging plate (typically 200 mm / s) which on the one hand increases safety and on the other hand significantly increases comfort, especially with short stops in the stations.
- a bridging device can be fastened either to the rail vehicle or to the platform.
- the bridging plate is displaceably mounted on the platform.
- Guide rails include a lower stationary guide rail and an upper movable, connected to the bridging plate guide rail, and that at at least one guide rail, preferably in both guide rails, the upper guide rail with respect to the lower guide rail so far tilted about a horizontal, arranged perpendicular to the direction of tilting axis is tilted slightly that when loads the bridging plate from above with a minimum force in the range of a typical minimum weight of Passengers a non-positive detection of the upper guide rail takes place.
- This automatic detection leads to increased safety, since the bridging plate is mechanically blocked under load from a minimum force (typically about 100N).
- the ease of movement is so high that should be provided such a mechanism, and also in a ball linear guide or roller linear guide the directional stability is so high that this tiltable storage should be expressly provided constructive.
- at least one spring element preferably two offset in the displacement direction spring elements are arranged between the upper guide rail and the lower guide rail, wherein the spring elements are particularly preferably designed as spring plates.
- the lower guide rail has at least one extending in the direction of displacement longitudinal groove, and that the upper guide rail has at least one in this longitudinal groove at least partially engaging horizontal rib, and that the non-positive determination by tilting the rib takes place in the longitudinal groove.
- the lower guide rail has two longitudinal grooves open to the side in the horizontal direction and the upper guide rail has two ribs extending inwards in the horizontal direction, with the ribs particularly preferably extending over at least half of them to substantially the entire length of the upper guide rail or the ribs are respectively arranged in two substantially terminal portions of the upper guide rail.
- a locking device that is essentially provided for this purpose to lock the bridging plate in the extended or in the retracted position (and possibly also in other positions).
- a locking device can be designed preferably electromagnetically releasable, and it has particularly preferably for safety's sake via a manual release.
- the locking device can intervene, for example, via a locking rod in corresponding recesses in or on the bridging plate in specific intended positions.
- the lock preferably fixes on the one hand the sliding step in a defined position (preferably in the retracted) and at the same time the locking device reports this status to the controller or to higher-level systems (in one movement). It is also possible to perform these two functions with two elements (one fixes the position, another indicates the status), but this often causes problems if both elements do not have the same status (sliding step fixed, but signal is not displayed; Signal is displayed but sliding step is not mechanically locked etc.). This problem is circumvented here by the fact that both, locking and status message, are realized with the same device.
- the upper guide rail comprises a profile portion and an upper guide plate, which guide plate is fixedly connected to an upper guide insert, which together with a lower guide insert which is fixed to the lower guide rail, the ball linear guide or roller linear guide forms, and that the guide plate is tiltably connected via two offset in the direction of displacement spring plates with a horizontal portion of the profile area.
- a further preferred embodiment is characterized in that at least three, in particular preferably at least four parallel guide rails are provided for a bridging plate.
- the toothed belt is preferably attached with its two ends to the bridging plate and / or on the upper guide rail and is coupled via at least one pulley to a drive gear of a stationary motor , and wherein furthermore preferably the axis of the motor is arranged substantially horizontally and the shaft of the drive gear, which is preferably driven via a worm gear, is arranged vertically, for example.
- the entire apparatus is preferably designed substantially box-shaped and intended to be either embedded in a recess in the platform or to be embedded in a recess in the region of the rail vehicle, or to be placed on the platform.
- the overall height of the entire device is particularly preferably in the range of less than 70 mm, particularly preferably in the range of less than 55 mm.
- the entire device has insulating coatings in the surface areas exposed to the passengers. Possible coatings consist of plastics such as e.g. Polyester or polyamides, preferably as fiber-reinforced coatings, e.g. fiber reinforced polyamide.
- the individual components that are exposed to the passengers, as a whole may consist of an insulating material, such as profiles or plates, etc. made of glass fiber reinforced plastic (for example, glass fiber reinforced polyester).
- glass fiber reinforced plastic for example, glass fiber reinforced polyester
- materials or coatings as available from Fiberline Composites A / S, DK; Gatex Kunststoffbearbeitung GmbH, DE; or Durapol type, available from Von Roll Isola, FR If the device is e.g. attached to the railway car, insulation is not mandatory.
- Housing comprising a bottom, lateral side walls, a rear wall and a front wall, wherein in this housing, the guide rails are arranged, and that a stationary cover plate is provided on the platform, or the rail vehicle in the event that the device is fastened to the rail vehicle, under which the bridging plate essentially lies in the retracted position, and below which the bridging plate in the extended position only comes to rest with the rear edge area.
- a stationary cover plate is provided on the platform, or the rail vehicle in the event that the device is fastened to the rail vehicle, under which the bridging plate essentially lies in the retracted position, and below which the bridging plate in the extended position only comes to rest with the rear edge area.
- sliding elements also rollers are possible
- the sliding elements are particularly preferred than in the formed over the entire width of the bridging plate extending plastic strips or plastic ribs substantially.
- only one drive is arranged in such a device, and this drive engages only on a single guide rail, in particular preferably only on one of the two outermost guide rails.
- means are arranged, which couple the movement of the driven guide rail to the movement of at least one further guide rail, in particular preferably the opposite outermost guide rail.
- Fig. 1 is a perspective view of a lock-up device, wherein the Cover is removed;
- FIG. 2 is a perspective view of the region of a guide with the bridging plate and the cover plate omitted;
- 3 is a plan view of a lock-up device; 4 shows a vertical section perpendicular to the running direction of the platform, wherein the bridging plate is in the retracted state.
- Figure 5 is a vertical section perpendicular to the direction of travel of the platform, wherein the bridging plate is in the extended state.
- FIG. 7 shows the upper guide rail, wherein in a) a perspective view from below is shown, in b) a vertical section perpendicular to the direction of displacement and in c) a vertical section parallel to the direction of displacement is shown.
- FIG. 1 shows a perspective view of a bridging device.
- the bridging device in this case comprises a bridging plate 1, which is displaceably mounted with respect to a housing 3.
- the housing 3 is either bolted to a platform or attached to the rail vehicle.
- the proposed lock-up device can be used both to bridge the gap by being fixed to the platform and extended after retraction of the train, or it can be used to bridge the gap between the platform and the rail vehicle by moving it Door region of the rail vehicle is attached and after reaching the end position of the train is extended in the direction of the platform.
- the lock-up device finds application in that the housing is mounted on the platform.
- the housing 3 comprises a bottom 9, two side walls 7 and a rear wall 8.
- the side walls and rear wall are not absolutely necessary, however, if the device is arranged, for example, in a recess in the platform.
- the housing may have a front wall 16.
- the housing has a cover plate 26, which has been omitted for better visibility of the suspension of the bridging plate 1 in the perspective view according to FIG.
- the bridging plate 1 is an elongated, generally rectangular metal plate, which comprises a horizontal plate 15 and preferably one of the
- the bridging plate is somewhat L-shaped with the short leg directed downwards.
- This embodiment also has the advantage that when retracted
- the bridging plate has a top 13, as well as a bottom 14.
- the top 13 is intended as a tread for the
- the bridging plate is slidable at the stationary
- Guide rails are arranged substantially perpendicular to the platform edge horizontally and comprise a lower guide rail 6 which is fixed to the housing is and is stationary, and an upper guide rail 11, which are fixedly secured to the bridging plate 1, specifically on the underside 14 of the bridging plate 1. It has to be pointed out that in FIG. 1 only the lower guide rail 6 shown on the far left is shown completely. For illustration, only the base plate 10 has been illustrated in the two middle guide rails (see below), and the far right guide rail 6 has been omitted altogether.
- the bridging device also has a motor 4, which is ideally designed as an electric motor and is arranged only on one side in the region of the front edge of the housing.
- the motor may also be located in the center, if space permits, with respect to the uniformity of the movement, this is actually preferred.
- the proposed bridging device is preferably used in connection with so-called Platform Screen Doors, ie with a barrier device with a height in the range of one meter to two meters to delineate the platform area from the track area, as in such constructions due to existing doors in the Platform Gate Doors a clear definition for the position of the doors of the rail vehicle for entering and exiting is given.
- the invention can be applied to other platform terminations as well as at platform terminations, which are provided over the entire height and thus completely separate the rail area spatially from the platform area.
- the positioning of the motor 4 advantageously comes to lie behind a wall element of the separation structure between the platform and the rail area or behind the remainder of the sliding door remaining with the door open.
- FIG. 1 it can be seen in FIG. 1 that two parallel slide strips are arranged in the region of the trailing edge on the upper side 13 of the bridging plate.
- These are plastic strips which ensure that no strong friction between the underside of the cover plate 26 and the top of the lock-up plate can occur, which would hinder the displacement of the lock-up plate.
- the surface of the bridging plate is typically provided with a non-slip and insulating coating 27, and it is inevitable that the cover plate has to bridge a large distance between the two side walls 7 of the housing 3. It is thus very possible that when several passengers are on the cover plate 26 in particular in the central region, this cover plate 26 bends considerably downwards.
- the wear strips 5 are provided. As already explained, these are plastic strips which are screwed tight to the upper side 13.
- the plastic may be, for example, Teflon or else other plastics such as polyethylenes, in particular UHMW-PE, for example UHMW-PE / PE-1000 polyethylene as available from Maagtechnic, CH, or Duragliss from Plüss & Co, CH.
- UHMW-PE for example UHMW-PE / PE-1000 polyethylene as available from Maagtechnic, CH, or Duragliss from Plüss & Co, CH.
- the same function can be fulfilled by providing 5 small rollers instead of the slide bars. Under certain circumstances disadvantageous to such roles or balls is the fact that they are generally larger in terms of height and are associated with significant additional design effort.
- FIG. 2 shows a perspective view of the region of a guide, wherein again the cover plate has been omitted, and in this case also the bridging plate 1 has been left for better visibility of the suspension. Also not shown is the timing belt, whose function will be explained below.
- the housing 3 not only has a bottom 9 and side walls 3, but also preferably a front wall 16 for preventing soiling etc.
- the side walls 7 usually have an inwardly directed flange at the top edge which holes 18 are provided for fastening the cover plate 26.
- the housing for attachment of the motor has a lateral projection, on which a mounting plate 17, which, for example, as in Figure 2, L-shaped configuration, is attached.
- This mounting plate 17 is preferably designed such that the motor 4 attached thereto can be fastened in different positions in a direction substantially parallel to the platform leading edge. It is thus possible to adjust the tension of the toothed belt. Furthermore, it may prove advantageous to provide a spring force, so that an automatic tension of the toothed belt is ensured.
- the upper guide rail 11 is formed as a kind of downwardly directed U-shaped profile, wherein on the two downwardly directed legs additionally inwardly directed horizontal ribs 42 are arranged. Furthermore, this U-shaped profile is on both sides
- Reinforced L-shaped reinforcing profiles 39 are, for example, welded to the U-profile and increase the load capacity of the guide rail.
- the function of the two inwardly directed horizontal ribs 42 will be explained in detail below.
- the upper guide rail 11 moves together with the bridging plate 1. Accordingly, the drive is provided so that a toothed belt (not shown) via a front driver 19 is fixedly secured to the upper guide rail, then around the fixed on the housing 3 angeachste front guide roller 21st for the toothed belt, then to the left to the (not visible) drive gear of the motor 4, around this, again towards the upper guide rail to the rear pulley 22 for the toothed belt around and then to the rear driver 20, with which the other End of the belt is also connected to the upper guide rail.
- a toothed belt allows a very robust, reliable and yet strong coupling of the motor 4 to the upper guide rail 11.
- a displacement parallel to the platform edge of the mounting plate 17 is used to adjust the tension of the toothed belt can.
- the engine is as already explained preferably an electric motor, this can, for example, in the proposed arrangement at the front edge slightly laterally offset very easy to the controller resp.
- the engine has in this case via a worm gear 24, with which on the horizontally arranged shaft of the Engine generated power can be transmitted to a vertically arranged shaft 23 for the Antriebszalinrad.
- a pair of pulleys 25 is shown for the transverse compensation.
- These rollers make it possible, in particular when a motor is arranged only on one side of the bridging device, to couple the movement of the driven rail to adjacent rails via transverse compensation belts 43 or transverse compensation cords. Ideally, this coupling takes place so that it takes place on the opposite (in Figure 1 rightmost) guide rail, this to ensure that the sliding movement of the lock-up plate 1 runs as parallel as possible.
- a simple way of arranging such transverse balancing belt is, for example, given by in turn two drivers 44 are arranged on the upper guide rail, one at the front edge and one at the trailing edge.
- a cross balancing belt is then attached to the front driver 44, guided around the front pulley shown on the right and guided to the top right to the mirror-symmetrically arranged pair of guide rollers 25 in the upper right outer guide rail.
- the cross balancing belt is now guided over the rear pulley to the rear driver 44 of the upper rightmost guide rail arranged there and firmly connected to the upper guide rail.
- Figure 3 a plan view of a lock-up device.
- the cross compensation belt thus runs in the illustration according to Figure 3, first from the lower left position of the driver 44 to the lower guide roller 25 on the left side, then right to the upper guide roller 25 on the right side and then the rear driver 44 of the whole guided upper right guide rail 11 guided and fixed there.
- FIGS. 4 and 5 show the bridging device in the retracted position (FIG. 4) and in the extended position (FIG. 5) in a section in a vertical plane perpendicular to the direction of the platform edge, wherein different sectional planes have been used for FIGS. 4 and 5 to represent different components.
- FIG. 4 shows the bridging device in the retracted position (FIG. 4) and in the extended position (FIG. 5) in a section in a vertical plane perpendicular to the direction of the platform edge, wherein different sectional planes have been used for FIGS. 4 and 5 to represent different components.
- an insulating coating is useful for all areas exposed to the passengers, since it can not be ruled out that the rail vehicle is at a different potential than the track area.
- the Uberbrückungsplatte has on the lower inner side of the downwardly directed projection 2 via a parallel to the platform edge extending stabilizer plate 28. Furthermore, it can be seen in this figure that the lower guide rail has a base plate 10, which with screws 31st attached to the bottom 9 of the housing. Also on the bottom 9 of the
- Attached housing is the article 29, which will be explained in more detail below with reference to FIG 6.
- the Uberbschungsplatte 1 is designed tiltable with respect to the lower guide rail 6 about an axis perpendicular to the paper plane in Figure 1 by a small angle.
- the linear ball bearing or linear roller bearing is arranged so that the upper guide plate 37 is not rigidly and firmly connected to the Uberbrückungsplatte 1, but by in each case a flexible construction is provided at two offset in the displacement direction positions.
- this is a spring plate 38 at the two positions.
- Attachment 29 is secured by screws 31 on the bottom 9 of the housing 3. From above into this base plate 6 in an elongated recess in the cap 29 and in the base plate 6 of the lower guide insert 32 is screwed over the screws 33.
- Ball linear guide are not shown in Figure 6, they are located in the channel 35 and can either be provided freely or in a ball cage.
- This channel 35 is formed by corresponding elongated recesses in the upper guide insert 34 and in the lower guide insert 32.
- the upper guide insert 34 is thus mounted displaceably with respect to the lower guide insert 32.
- the upper guide insert 34 is now only indirectly connected to the upper guide rail 11, by the upper guide insert 34 is first firmly connected to an upper guide plate 37.
- This upper guide plate 37 is now connected to the horizontal portion 40 of the upper guide rail 11 via the two staggered, for example.
- Well-visible in Figure 4 spring plates 38.
- the spring plates 38 are screwed for this purpose with fastening screws 45 on section 40.
- spring plates 38 come z.
- metal sheets eg spring steel
- the already mentioned to some extent automatic non-positive mechanism for detecting the bridging plate under a load is now guaranteed as follows.
