Description

Technical Field

[0001] The platform door of the present invention is a type of platform door capable of separating a platform from a track area in which a train travels and stops and forming a passage for accessing the stopped train. Background Art

[0002] In a railway system consisting of a series of train stations and a series of trains running between the train stations, it is important that the boarding and alighting of passengers from the trains stopping at each station is carried out in a very flexible manner to avoid cumulative delays that will affect the overall operation of the train service. It is therefore crucial that the transfer between boarding and alighting of passengers can be carried out after the train arrives at the platform, the passengers have already approached the track area, and after the train has stopped and the train doors have been opened quickly.

[0003] In order to position passengers on the platform close to the stopping area of ​​the train, platform doors are usually used, which allow passengers to be safely located very close to the area where the train doors will be located without the risk of falling into the track area, as these platform doors are provided with closed doors that are only opened when the train is stopped at the platform.

[0004] Usually, platform doors are provided in the form of a barrier with a set of doors (usually sliding doors) which allow themselves to open once the train has stopped, thereby forming a passage corresponding to the train doors, thus allowing passengers to leave and enter the train. For example, document EP1964747 describes one of these platform doors.

[0005] However, this type of platform door exhibits the drawback of fixed door positions, which makes them only usable in stations where trains with doors of the same composition and configuration pass through or with overlapping door arrangements. This makes it difficult to use the platform door in stations where trains of different composition and configuration stop. This drawback may even make it impossible to update the train fleet without replacing the doors when new trains have different door arrangements, while gradual updating of trains is not feasible because the same train doors cannot be used in new and old trains.

[0006] Furthermore, it must be taken into account that the trains exhibit an error in the braking distance, making it impossible to clearly determine the position in which the train doors will be after the train has stopped. Therefore, in order to allow access from the train doors regardless of the stopping position of the train, the platform doors must be oversized to take into account this error. Oversized doors mean that they will have greater dimensions, greater weight and therefore, in addition to being more difficult to control, greater opening and closing times, since the doors must travel a greater distance between their open and closed positions. This drawback can be solved by using faster devices for closing and opening the doors. However, this makes the doors more difficult to control, since the doors will have to reach high speeds, especially in the case of oversized doors.

[0007] However, even if the doors are oversized, this does not prevent the train doors from not being properly aligned with the platform doors due to braking errors, which means that passengers will not be able to leave or enter the train and the train will have to move, resulting in loss of time, which may affect the overall service of the railway system.

[0008] To solve this problem, platform doors such as those described in document WO201273658 are known, in which the platform doors consist of a plurality of mobile units, each of which is provided with an expandable door, so that the units can be placed in the target position before the train arrives at the platform according to the distribution of the doors of the next train arriving at the platform (which must be known). Even so, due to the braking errors of the train, it will always be necessary to readjust the position of the mobile units depending on the final stopping position of the train, which will often prevent the train doors from opening immediately.

[0009] Therefore, the object of the present invention is to disclose a platform door which allows its use for different types of trains with different door arrangements and door sizes and further achieves an optimal opening and closing time after the train has stopped, regardless of the braking position of the train. Summary of the invention

[0010] The platform door for entering a train from a platform of the present invention is a type of platform door comprising a plurality of sliding movable plates (panels), which can slide horizontally, ie, slide laterally, along the platform in an independent manner by means of respective traction devices.

[0011] Fundamentally, the platform door is characterized in that each movable panel has a fixed panel length and is adapted to slide laterally (e.g. on one or more tracks) and be arranged adjacent to other movable panels so as to be presented in a closed position leaving no passage between the movable panels (i.e. adjacent panels are in contact with each other or leave a negligible space between them), and each movable panel is also adapted to slide laterally and at least partially overlap with one of its adjacent movable panels so as to be presented in an open position defining a passage between the movable panels for access to the train doors, so that the movable panels of the platform door can be presented in different positions and thus leave different passages (even different passage sizes) between the movable panels to thereby adapt to the arrangement of the doors of the trains parked in the platform (in the open position) and allow users to comfortably and conveniently get on and off the train, and the movable panels can be presented in a position in which the movable panels do not allow passage (in the closed position) to prevent users from entering the tracks when no trains are parked at the platform. In this way, interoperability between trains of different compositions and configurations is facilitated, as the platform doors can be adapted to the train door configuration of each type of train, which configuration may vary between different train companies or even between train models of the same company, or will vary depending on the type of carriages forming each train.

[0012] In a variant embodiment, starting from the closed position, the mobile plate is adapted to slide transversely and separate from any one of its adjacent mobile plates on one side or the other, thus allowing a passage to be left between any pair of adjacent mobile plates starting from the closed position.

[0013] In a variant embodiment, starting from the closed position, the mobile plate is adapted to overlap at least partially and telescopically with one of its adjacent mobile plates, so that the mobile plate of smaller size can enter the interior of the mobile plate of larger size, generally in the shape of an arch defining a hollow in the manner of a tunnel, in which the adjacent mobile plate of smaller size can be at least partially housed. It is also foreseeable that all the mobile plates have an arched shape, thus allowing each end of the arch to rest on the rail and achieve at least two support points and therefore better stability and resistance to lateral forces.

[0014] In a variant embodiment, starting from the closed position, each mobile panel is suitable for telescopically and completely overlapping one of its adjacent mobile panels, so that the panel of smaller size can be completely hidden inside the panel of larger size.

[0015] In a variant embodiment, starting from the closed position, each mobile plate is adapted to surpass (ie pass) one of its adjacent plates, two adjacent mobile plates being able to completely cross each other, thus enabling the two adjacent mobile plates to exchange positions.

[0016] In a variant embodiment, the plate length of each mobile plate is equal, so that in the closed position all mobile plates present a uniform display of the platform doors, further enabling, when the mobile plates are telescopic, one mobile plate to be inserted inside another mobile plate and to be perfectly adjusted inside the other mobile plate during the open position or during the transition between the closed position and the open position.

[0017] In a variant embodiment, in the closed position, at least one of the moving plates of each pair of adjacent moving plates is provided with a hollow portion defining a tunnel through the interior of the moving plates for the other moving plate to pass therethrough.

[0018] In a variant embodiment, in the closed position, at least one of each pair of adjacent mobile plates has a substantially arched shape, thereby defining two support points on the ground and achieving greater resistance to lateral forces (such as those that may be applied by people waiting for a train on the platform).

[0019] In a variant embodiment, in the closed position, adjacent movable panels have the first panel width and the second panel width in an alternating manner, so that the movable panels are telescopic in pairs.

[0020] In a variant embodiment, the platform door comprises at least one track on which the mobile plate of the platform door slides and is mounted, and the traction means are suitable for moving the mobile plate mounted on the track in an independent manner. Of course, the one or more tracks can be mounted on the platform floor so that the mobile plate will be held by the platform floor, or the one or more tracks can be mounted using the platform ceiling so that the mobile plate will be held by the platform ceiling, that is, the mobile plate will be suspended on the platform ceiling. It also means that the tracks are distributed between the platform floor and the platform ceiling so that some mobile plates are held on the floor and other mobile plates are held on the platform ceiling. In this way, each mobile plate will be able to move independently of the remaining mobile plates and then move between the closed position and the open position, thus presenting the configuration required for the configuration of the train door of the train parked at the platform. These traction means can be wheels actuated by motors that move the mobile plates, which can then be guided as appropriate, preferably along a straight line, because they are mounted on linear tracks. Of course, it is meant that if one moving plate must pass another adjacent moving plate, or overtake another moving plate in a parallel plane, there may be different sets of tracks. Other pulling means are contemplated, such as electromagnetic moving means.

[0021] In a variant embodiment, the platform door comprises a pair of tracks, each mobile plate being mounted on a pair of tracks and thus allowing greater stability and resistance to lateral forces.

[0022] In a variant embodiment, each mobile panel comprises return means adapted to actuate the traction means of each mobile panel to return from the open position to the closed position. These return means can memorize the original position or the movement of each mobile panel between the closed position and the open position, in order to cancel the movement by actuating the traction means in a timely manner, the mobile panel thus returning quickly to the closed position.

[0023] A system is also disclosed, which includes a platform door installed on a platform, and a train with one or more train doors parked at the platform, the system being provided with a detection device for detecting the position of the train door of the train, and a control device, which is suitable for defining one or more movable plates of the platform door arranged in front of each train door, and actuating these movable plates to open respective passages in front of each train door, thereby presenting an open position.

[0024] In a variant embodiment, the length of each moving plate is equal to or greater than the train door length of each train door (ie its width or free passage), so that only one or two plates per train door have to be moved to open the platform door.

[0025] In a variant embodiment, the detection means comprise a detector for detecting the position of the head of a train parked beside the platform, making it possible to quickly report misalignment due to errors in the parking area of ​​the train in order to quickly prepare the mobile plate.

[0026] In a variant embodiment, the distance between the train doors is greater than the panel length, so that several mobile panels can be arranged between the train doors, and the mobile panel can have a smaller size, thereby facilitating its movement and modularity.

[0027] A method of actuating the platform doors of the described system from a closed position in which there is no passage between the moving plates, based on the arrival of a train provided with train doors, is also disclosed, the method comprising the steps of: detecting one or more moving plates arranged in front of each train door once the train has stopped at the platform; and sliding the detected one or more moving plates laterally to open the respective access passage in front of each train door, thereby assuming the open position. In the embodiment of interest, the method further comprises the step of returning each plate that has been moved laterally after assuming the open position until it again assumes the previous closed position of the platform door.

[0039] Figure 1 , Figure 2 and Figure 3A platform door 1 for access to a train door 2 from a platform 3 is shown, the platform door comprising a plurality of sliding mobile panels 5 which can slide transversely in an independent manner, for example on one or more tracks, by means of respective traction devices 6. It is shown that each mobile panel 5 is rigid and has a fixed panel length l1, preferably the panel length l1 of each panel 5 is equal, and is arranged adjacent to the other mobile panels 5, so as to be presented in a closed position A without a passage between the mobile panels 5, and each mobile panel 5 is also suitable for sliding transversely and overlapping at least partially with one of its adjacent mobile panels 5, so as to be presented in an open position B and define a passage 7 between the mobile panels 5 for access to a train door 4 parked at the platform 3. Moreover, starting from the closed position A, the mobile panel 5 is suitable for sliding transversely and separating from any of its adjacent mobile panels 5. Therefore, starting from the closed position A, each movable plate can slide and move independently of other movable plates 5, even at different speeds and in different directions, and can determine different strokes, and the movement of the movable plate 5 starting from the closed position A will not cause the movement of another movable plate.

[0040] Figure 1 and Figure 2 The platform door 1 represented in the figure is formed by a telescopic movable plate 5, which is suitable for at least partially and telescopically overlapping one of its adjacent movable plates 5, so that the movable plate 5 can slide and form a single body (monobody) with at least the adjacent movable plate 5, one inserted into the inside of the other.

[0041] Figure 1 An embodiment with two levels (ie, two plate widths w1, w2) is shown, so that the moving plates 5 can be telescopically overlapped and every two moving plates 5 form a single body; and Figure 2 An embodiment with three levels (i.e., three board widths) is shown, so that the moving boards 5 can slide and form a single body in groups of three. Of course, other platform doors 1 with several telescopic levels can also be envisioned, so that the moving boards 5 can be linked together and combined with their adjacent moving boards 5.

[0042] It also means that the mobile plates 5 are arranged in rows 14, for example Figure 3The embodiment of the platform door 1 is shown in the figure, wherein the movable panels 5 are arranged in two rows 14 and they can be arranged adjacent to other movable panels 5 of another row 14 so as to be presented in a closed position A without leaving a passage between the movable panels 5. It can be seen that in the closed position A, the movable panels 5 are arranged one after another in a continuous manner, for example in alternating rows 14 without leaving a passage between the movable panels 5. In addition, each sliding movable panel 5 is suitable for sliding laterally and overlapping at least partially with one of its adjacent movable panels 5, in this case overlapping with the adjacent movable panels in the other row 14, so as to be presented in an open position B and define a passage 7 between the movable panels 5 for access to the train door 4 parked at the platform 3. Of course, although not shown in these figures, it is meant that the movable panels 5 can even surpass their adjacent movable panels 5 to be presented in the closed position A or the open position B as the case may be, thus giving the arrangement of the movable panels 5 great flexibility. It is particularly emphasized that the flexibility of the arrangement of the movable panels 5 is a common feature of all the embodiments of the platform door 1 shown. Although the Figure 3 It is shown that all the moving plates 5 have the same plate length l1, which also means that the plates can have different plate lengths l1 as appropriate, for example, the plate length l1 of the end moving plates 5 is larger, while the plate length l1 of the central moving plate 5 is smaller, thereby facilitating the rapid movement of the central moving plate. In this case, the heights of the moving plates 5 can be the same.

[0043] exist Figure 1 and Figure 2 In the telescopic mobile panels 5 shown, for example, starting from the closed position A, each mobile panel 5 is adapted to telescopically and completely overlap one of its adjacent mobile panels 5. Starting from the closed position A, it is also meant that each mobile panel 5 is not only adapted to overlap one of its adjacent mobile panels 5, but also to even make the mobile panel 5 surpass one of its adjacent mobile panels 5, so that different combinations between the mobile panels 5 are possible, and the passage 7 is defined as appropriate, so that when the train 4 stops at the platform 3, the passage 7 of the train door 1 coincides with the train door 2, thus allowing passengers to enter and leave the train 4.

[0044] Figure 4a It shows that previously Figure 1 , but in an open position B, wherein a passage 7 is defined between the moving plates 5, for example for access to a door of a train 4 parked at the platform 3, as will be described later. It can be seen that some moving plates 5 partially overlap with their adjacent moving plates 5, while some moving plates 5 completely overlap with their adjacent moving plates 5, and moving plates 5 with the same plate width w1, w2 are locked. In this way, great versatility is achieved to form a passage 7 in the platform door 1 and to be able to adapt to different arrangements of train doors 2.

[0045] Figure 4bShows Figure 4a CC cross-sectional view of. The figure shows that, in the closed position A, at least one of each pair of adjacent moving plates 5 is provided with a hollow portion 13 (in the form of a tunnel across the moving plates 5) for the other moving plate 5 to pass therethrough, so that one moving plate 5 can pass through the other moving plate 5. The embodiment shown is a telescopic moving plate 5 with two levels. For a telescopic moving plate 5 with three levels, two moving plates 5 with holes 13 will be provided, and the smaller moving plate can pass through the inside of the hole 13 of the larger moving plate, while the moving plate 5 without the hollow portion 13 can pass through the hole of the smaller moving plate 5 with the hollow portion 13. Therefore, in the closed position A, at least one of each pair of adjacent moving plates 5 has a generally arched shape, and even all the moving plates can have a generally arched shape, which confers greater stability and resistance to lateral forces (such as forces that may be applied by people waiting for the train 4 on the platform 3).

[0046] Figure 4b It is shown that the moving plates 5 of the platform door 1 have a first plate width w1 and a second plate width w2 in an alternating manner, and that one moving plate 5 can pass through the hollow portion 13 of another moving plate 5. The height of each moving plate 5 will also be a height suitable for enabling a telescopic effect, and the heights will generally be alternating, with the moving plate 5 having a smaller height being the moving plate 5 that must pass through the hollow portion 13 of another moving plate 5.

[0047] Furthermore, the mobile board 5 is mounted on a set of rails 12, which may be one or more rails, and the mobile board 5 is in turn provided with traction devices 6 suitable for independently moving the mobile board 5 mounted on the rails 12, which traction devices 6 may be, for example, drive wheels. Of course, other traction devices 6 capable of moving the mobile board 5 laterally along the platform 3 are also intended.

[0048] Figure 5a to Figure 5d It shows the different configurations that the sliding mobile plate 5 of the platform door 1 can assume (or take), in particular, Figure 5a A position is shown in which the mobile plates 5 are arranged adjacent to each other without leaving any space between them; Figure 5b The movement of one of the moving plates 5 (the smaller plate) is shown until it is partially inserted inside (through the hollow 13 of) the other moving plate 5 (the larger plate), leaving a passage 7 between the moving plates 5. Figure 5c The method of showing that the smaller moving plate 5 can completely cross the larger moving plate 5, which moves in one direction while the larger plate moves in the opposite direction, the larger plate and the smaller plate relative to each other Figure 5cSince each mobile plate 5 can be moved in an independent manner, they can even be moved away from each other, making it possible to Figure 5d The respective channel 7 is realized in the manner shown in FIG.

[0049] Figure 6a and Figure 6b Another sliding mobile plate 5 of a platform door 1 is shown, wherein the mobile plates 5 are rigid, can slide transversely and can be moved in two rows 14 in two parallel planes so that they can at least overlap their adjacent mobile plates 5 . Figure 6a The mobile panels 5 are shown in the closed position A of the platform door 1, wherein there are no passages 7 between the mobile panels 5, the mobile panels 5 being arranged in an alternating manner in each row 14, and Figure 6b The moving plates 5 are shown in an open position B of the platform door 1 , wherein there is a passage 7 between the moving plates 5 and a moving plate 5 at least overlaps its neighboring moving plates 5 , or even exceeds its neighboring moving plates 5 .

[0050] It is further pointed out that Figures 5a to 6b The platform door 1 shown in the figure is presented with a pair of tracks 12, on which each movable plate 5 is mounted, so that, for example, a movable plate having a generally arched shape can support each of its ends on a track 12 different from the pair of tracks 12, thereby imparting enhanced stability and resistance to lateral forces.

[0051] Figure 7a , Figure 7b and Figure 7c A system 100 is shown, which comprises a platform door 1 mounted on a platform 3 and a train 4 having one or more train doors 2 (three train doors 2 in this case), the train 4 being parked at the platform 3 . Figure 7a and Figure 7b The system 100 is shown with the platform door 1 in the closed position A. The system 100 is provided with a detection device 9 for detecting the position of the train door 2, and a control device 10 adapted to define one or more sliding movable plates 5 of the platform door 1 arranged in front of each train door 2 and to actuate these movable plates 5 to move them and open the respective access passage 7 in front of each train door 2, thereby presenting Figure 7cThe open position B shown. The detection device 9 can obtain information from the train 4 (for example from the railway signal system) and can be combined with (including) a transponder suitable for receiving information directly from the train and detecting the stopping point of the train at the platform 3. It means that the detection device 9 includes a detector that detects the position of the head 11 of the train 4 parked beside the platform 3, so that the misalignment caused by errors in the parking area of ​​the train can be quickly reported to quickly prepare the mobile plate 5. Therefore, the detection device 9 can obtain information from the train 4 (for example its length and door configuration) and transmit this information to the control device 10 that will define the mobile plate 5 that must be moved to present in the open position B. Of course, it also means that the detection device 9 can be arranged along the platform 3 or in the platform door 1 (for example in the mobile plate 5) and is suitable for detecting a passive signal placed in the train 4 (when the train is parked at the platform 3, the passive signal can define the position of the train door 2 so that the control device 10 actuates the mobile plate 5). It is also meant that the detection device 9 can communicate with active devices arranged in the train 4 so that communication is established between the train 4 and the platform 3 to obtain the door configuration of the train. It is also meant that it is envisaged that the detection device 9 can also be arranged away from the platform 3 and, for example, provided with a camera oriented toward the platform 3, so that the door configuration of the train 4 and the position of the mobile plate 5 can be obtained by processing the captured image, so as to define the mobile plate 5 that must be moved to open the platform door. It is also meant that the detection device 9 and the control device 10 can be integrated in the same device. It is also meant that each mobile plate 5 has a dedicated detection device 9 and control device 10, for example, which detects that when the train 4 stops at the platform 3, one of the train doors 2 is arranged in front of the mobile plate 5, and the mobile plate 5 can thus be moved in an autonomous manner between the closed position A (at which the mobile plate 5 is arranged in front of the train door 2) and the open position B (at which the mobile plate 5 is away from the train door 2).

[0052] After moving the defined moving plate 5 (indicated by the corresponding dashed arrow), and after presenting the Figure 7c In the open position B shown, passengers can board the train 4 (get on the train) and get off the train 4. Preferably, the plate length l1 of each mobile plate 5 will be equal to or greater than the train door length l2 of each train door 2 to minimize the number of mobile plates 5 to be moved between the closed position A and the open position B. However, since the train door length l2 or its arrangement will generally not be known in advance, the necessary movements of the mobile plates 5 will have to be performed to enable access to the train 4 from the platform 3. It is also desirable that the distance l3 between the train doors is greater than the plate length l1 to thereby minimize the movement of the mobile plates 5. However, as previously mentioned, if the type of train 4, the arrangement of the train doors 2 or the distance l3 between the train doors are not known, the necessary movements of the mobile plates 5 will have to be performed to open the passage 7 and enable access to the train 4 from the platform 3.

[0053] Each mobile plate 5 of the platform door 1 is intended to also include return means suitable for actuating the traction means 6 of each mobile plate 5 to return the mobile plate 5 to the closed position A so that the passage 7 possibly between the mobile plates 5 is closed and the platform door 1 can be ready to receive another train 4. The return means can be a computer programmed to undo the path travelled by each mobile plate 5 between the closed position A and the open position B, or even simply a rotary encoder which counts the number of revolutions of the wheels of each mobile plate 5 during movement on the track 12 and actuates the traction means 6 so that the wheels turn the same number of revolutions in the opposite direction to return the mobile plate 5 to the previous closed position A. It is meant that these return means can also be centralized and allow issuing instructions to each of the mobile plates 5 to return them to the closed position A.

[0054] Thus, in a case where the platform door 1 is in the closed position A and there is no passage 7 between the moving plates 5 and in which the train 4 is provided with a train door 2 Figure 7a and Figure 7b As shown in FIG. 1 , based on the arrival of a train 4, an actuation method for opening the platform door will be executed, the actuation method comprising the following steps: once the train 4 stops beside the platform 3, detecting one or more moving plates 5 arranged in front of each train door 2; and sliding or moving the detected one or more moving plates 5 laterally to open respective access passages 7 (such as Figure 6b As shown by the arrow in the figure, Figure 7c The open position shown in B.

[0055] Of course, after assuming the open position B, and preferably before the train 4 leaves the platform 3, for example, once the train door 2 is closed, or while the train door 2 is closed, the platform door 1 will perform the following steps, namely, returning each movable plate 5 that has been moved laterally until it again assumes the previous closed position A of the platform door 1, so that the passage 7 between the platform 3 and the train 4 is closed, thereby preventing access to the track without a train 4 parked next to the platform.

[0056] The platform door 1 of the present invention allows adapting to a wide variety of train door 2 arrangements without prior adjustment or pre-programming, and only requires moving its moving plate 5 as needed. Therefore, if a train 4 arriving at the platform 3 has other numbers and arrangements of train doors 2 (e.g. Figure 8a , 8b and train 4 shown in 8c, Figure 9a and 9b Train 4 or Fig.10a and Fig.10bThe detection device 9 for detecting the position of the train door 2 will allow the required mobile plate 5 to be actuated and moved to open the respective passage 7 in front of each train door 2, thereby presenting the open position B and thus enabling access to the train door 2 from the platform, and then returning the mobile plate 5 to its initial position, thereby closing the passage 7 and returning again to the closed position A, waiting for the arrival of a new train 4.

[0057] Although in the foregoing embodiment, the moving plate 5 of the platform door 1 slides and moves in a lateral straight line, it means that the platform door 1 may have other shapes according to the shape of each platform 3. For example, Fig.11a and Fig.11b Another embodiment of the platform door 1 of the present invention is shown in a curved arrangement. Fig.10a The closed position A is shown. Fig.11b The open position B is shown.
