Description

Platform screen door device for heterogeneous railway vehicles

The present invention relates to a platform screen door device for heterogeneous railway vehicles. More specifically, it is installed on a platform where different types of railroad cars stop to separate the track and platform, and an entrance or exit that can be opened and closed selectively or in common corresponding to the entrance door for different types of railroad cars is installed, and the entrance is installed. The present invention relates to a platform screen door device for heterogeneous railroad vehicles that enables a stable boarding and disembarkation process for all different types of railroad cars by controlling the selective opening and closing of only the entrances corresponding to the railroad cars.

In general, subway or subway stations have tracks on which trains can move or stop, and platforms at a certain height for passengers to board or get off the train. According to this structure, when the train enters the platform through the tracks and stops, when the door of the train is opened, passengers get on or get off.

However, since most platforms and tracks do not have any protective guards or security measures installed, accidents occur frequently where passengers fall onto the tracks and are injured, or when a train enters the train, they fall voluntarily or intentionally, resulting in fatal injury or loss of life. There was a problem.

In order to prevent such accidents, various types of safety guards have recently been installed at certain locations on the platforms. However, when the train is stopped, these safety guards cannot be installed in the area where the door is located, so accidents such as the above-mentioned ones are completely prevented. There was a problem that could not be prevented.

Accordingly, platform screen doors (PSDs: Platform Screen Doors) have recently been installed to enable passengers to board and disembark safely by sliding the screen doors in conjunction with the doors of electric trains.

This platform screen door has a plurality of vertical beams installed at equal intervals along the direction of travel of the train at the podium of the platform, and screen door modules are installed between adjacent vertical beams. The screen door module generally includes a horizontal rail disposed in the space between the vertical beams, a fixed door fixedly mounted between the vertical beams to form an entrance for passengers to board and disembark in some of the areas between the vertical beams, and a horizontal rail between the vertical beams. It is composed of a movable door that moves horizontally along the rail and operates to open and close the entrance. The movable door is controlled by the control unit to open and close in conjunction with the train's entrance door.

A typical platform is installed to allow one type of train to enter. Accordingly, the platform screen door is also installed in a position corresponding to the entrance door of the train when the train enters and stops, and is linked to the open/closed state of the train's entrance door. The movable door is configured to open and close.

However, with the recent expansion of railway lines, there is a situation where various types of railway vehicles, such as general railway vehicles or high-speed railway vehicles as well as subway-type electric trains, must enter one railway station. In particular, the space of the railway station has arisen. Taking utilization aspects into consideration, platforms are being designed in such a way that various types of railroad vehicles can all enter one platform.

In this way, when various types of railroad cars enter one platform, the length and shape of the railroad cars as well as the positions of the entrance doors are formed differently for each railroad car, so the existing general platform screen doors alone can be used to It is not possible to provide safe entry and exit functions for rail vehicles. In particular, since the positions of the entrance doors are different for each type of railway vehicle, there is a problem that a general platform screen door device in which the entrance and exit position of the screen door opened and closed by a movable door is fixed cannot be applied to all different railway vehicles.

The present invention was invented to solve the problems of the prior art, and the purpose of the present invention is to install on a platform where different types of railroad cars stop, to separate the track and the platform, and to provide an access door for different types of railroad cars. A heterogeneous railway that enables a stable boarding and disembarking process for all different types of railway vehicles by installing entrances and exits that can be opened and closed selectively or in common, and controlling only the entrances corresponding to the entering railway vehicles to be opened and closed selectively. The purpose is to provide a vehicle platform screen door device.

In this way, the opening width ( .

Meanwhile, the screen door module 200 is formed as a single slide structure as shown in FIG. 8 or a double slide structure as shown in FIG. 9 depending on the operation method of the movable door 220.

As shown in FIG. 8, the screen door module 200 of a single slide structure has fixed doors 210 disposed at both ends and a movable door 220 at the center, and the movable door 220 has two The door panels 220a are formed to slide simultaneously in opposite directions.

A horizontal rail 230 is formed at the upper end of the space between the vertical beams 100, and the door panel 220a is configured to move horizontally along the horizontal rail 230. The door driver 240, which moves the door panel 220a, is disposed at the upper end of the space between the vertical beams 100. The door driver 240 includes a rotary pulley 241 disposed at both ends, and a rotary pulley ( It is configured to include a transfer belt 242 that is wound around 241 and rotates, and a drive motor 243 that rotates the rotation pulley 241. Each door panel 220a is coupled to the upper section and lower section of the transfer belt 242 through separate connection brackets, and moves in opposite directions as the transfer belt 242 rotates.

As shown in FIG. 9, the screen door module 200 of a double slide structure has fixed doors 210 disposed at both ends and a movable door 220 at the center, and the movable door 220 has 2 The two left door panels 220a and the two right door panels 220a slide and move simultaneously in opposite directions, and the two left door panels 220a move in the same direction so as to be folded or deployed into the fixed door 210 area on the left. The two right door panels 220a are configured to slide in the same direction so as to be folded or unfolded into the area of the fixed door 210 on the right.

In the double slide structure, two horizontal rails (230,230-1) are arranged so that one pair of left and right door panels (220a) and the remaining pair of left and right door panels (220a) move along different horizontal rails (230,230-1), respectively. do. The door driving unit 240 includes two pairs of rotary pulleys 241 disposed at both ends, two transport belts 242 and 242-1 that are wound around each pair of rotary pulleys 241 and rotate, and a rotary pulley. It is configured to include a drive motor 243 that rotates 241. The two transport belts 242 and 242-1 are connected through a separate coupler 244 and configured to rotate simultaneously. According to this structure, when the drive motor 243 rotates only one rotation pulley 241, both transport belts 242 and 242-1 rotate in the same direction.

A pair of left and right door panels 220a are coupled to the upper section and lower section of one transfer belt 242 through separate connection brackets, and the remaining pair of left and right door panels 220a are connected to the remaining one transfer belt.

The double slide structure shown in FIG. 9 is a simplified conceptual diagram, and can be modified in various ways.

According to this structure, the screen door module 200 of the double slide structure can have the opening width (X) of the entrance 201 relatively wider than that of the single slide structure due to its operational structure, and the opening width Despite the wide width (X), relatively quick opening and closing operations are possible.

Next, we will look at the installation positions and shapes of the first group of screen door modules 200a, the second group of screen door modules 200b, and the third group of screen door modules 200c in more detail.

First, one screen door module 200b of the second group is installed as shown in FIGS. 1 to 7, and among the screen door modules 200c of the third group, a screen door module installed at the outermost one in one direction and It is located between the adjacent first group of screen door modules (200a).

As shown in FIG. 2, the second group of screen door modules 200b has a movable door 220 and a fixed door 210 disposed between the vertical beams 100 located on both sides, and the movable door 220 may be formed as a double slide structure in which the two door panels 220a slide in the same direction to be folded or unfolded in the fixed door 210 area.

Figure 9 shows a double slide structure in which four door panels 220a move two by two to fold or unfold in different directions. The second group of screen door modules 200b has the configuration shown in Figure 9. It may be configured in such a way that only one side is provided based on the center line. That is, the movable door 220 is provided with only two door panels 220a, and the two door panels 220a are folded into one fixed door 210 area to open the entrance 201 or the fixed door 210. ) It can be configured to unfold from the central direction to close the entrance 201.

The screen door module 200b of the second group has a corresponding entrance 201 area corresponding only to the area of the entrance door 21 of the second railroad car 20, and the screen door module 200c of the first and third groups ) means that the area of the entrance 201 corresponds individually or jointly to the area of the entrance door 11 of the first railway vehicle 10, so the platform screen door device for heterogeneous railway vehicles according to an embodiment of the present invention is the first In addition to the number of entrances 201 corresponding to the number of entrance doors 11 of the railway vehicle 10, entrances 201 corresponding to the entrance doors 21 of the second railway vehicle 20 (screen doors of the second group) The entrance 201 of the module 200b is installed with only one additional entrance.

Next, the first group of screen door modules 200a, which correspond only to the entrance door 11 of the first railway vehicle 10, has a general single slide structure or a double slide structure.

Among the screen door modules (200a) of the first group, the screen door module (200a-1) in which the center (CL) of the entrance (201) does not coincide with the center (C) of the entrance door (11) of the first railroad car (10) ), as shown in FIGS. 3 and 4, a movable door 220 and a fixed door 210 are disposed between the vertical beams 100 located on both sides, and the movable door 220 is composed of two door panels. (220a) is formed as a double slide structure that slides in the same direction to be folded or unfolded into the fixed door 210 area. At this time, the double slide structure, like the second group of screen door modules 200b, may be configured to have only one side based on the center line of the configuration shown in FIG. 9.

In this way, the first group of screen door modules 200a has a single slide structure depending on whether the center CL of the entrance 201 coincides with the center C of the entrance door 11 of the first railroad car 10. Alternatively, it is formed to have a double slide structure, and if the mutual centers are mismatched, the double slide structure can have a relatively wide opening width ( can be improved.

The third group of screen door modules 200c is formed such that the opening width It is formed to be larger than the standard value than the maximum opening width (d3) of the overlapped access doors (11, 21). At this time, the maximum opening width (d3) of the corresponding overlapped access doors (11, 21) is larger than the maximum opening width (d3) of the overlapped access doors (11, 21). It is formed differently depending on whether it is larger than the opening width d1 of the entrance door 11 of 10).

In one embodiment of the present invention, the opening width d1 of the entrance door 11 of the first railway car 10 is larger than the opening width d2 of the entrance door 21 of the second railway car 20. is formed Therefore, if the entrance doors 11 and 22 of the first and

second railway vehicles

second railroad cars

10 and 20 are located so that only a portion overlaps, the overlapping access door 11 The maximum opening width d3 of ,22) is formed to be larger than the opening width d1 of the entrance door 11 of the first railroad car 10. In this case, it is natural that the maximum opening width d3 of the overlapping entrance doors 11 and 22 is larger than the opening width d2 of the entrance door 21 of the second railroad car 20.

Among the third group of screen door modules (200c), the maximum opening width (d3) of the overlapping access doors (11, 21) corresponding to the entrance (201) of the third group of screen door modules (200c) is that of the first railroad car ( 10), if it is larger than the opening width d1 of the entrance door 11, that is, if the entrance doors 11 and 22 of the first and

second railway cars

10 and 20 are located so that only a portion overlaps, the screen As shown in FIGS. 4, 5, and 7, the door module 200c-1 has fixed doors 210 disposed at both ends and a movable door 220 at the center, and the movable door 220 ), the two left door panels 220a and the two right door panels 220a slide and move simultaneously in opposite directions, and the two left door panels 220a are folded into the area of the fixed door 210 on the left. It is formed as a double slide structure that slides in the same direction to be unfolded, and the two right door panels 220a are folded into the area of the fixed door 210 on the right side or is formed as a double slide structure that slides in the same direction to be unfolded. That is, it is formed in the double slide structure shown in FIG. 9.

Among the third group of screen door modules 200c, the maximum opening width d3 of the overlapping

access doors

In this case, as shown in Figure 2, the screen door module 200c-3 has a movable door 220 and a fixed door 210 disposed between the vertical beams 100 located on both sides, and a movable door ( 220) is formed as a double slide structure in which the two door panels 220a slide in the same direction to be folded or unfolded into the fixed door 210 area.

Here, the maximum opening width d3 of the overlapping

access doors

11 and 21 corresponding to the entrance 201 of the third group of screen door modules 200c is equal to that of the access door 11 of the first railroad car 10. Being equal to the opening width d1 means that the entrance doors 11 and 22 of the first and

second railroad cars

10 and 20 are positioned to completely overlap, as described above.

As described above, the third group of screen door modules (200c) have a double slide structure using four door panels (220a) when the corresponding entrance (201) has a relatively wide opening width (d3). , in the case of having a relatively small opening width (d3), a single slide or double slide structure is applied depending on whether the center coincides with the entrance door, and thus the space efficiency of the platform where the first and second railway vehicles stop By improving the screen door device, the screen door device can be operated more stably.

That is, when the movable doors 220 of a plurality of screen door modules 200 are simultaneously opened in a closed state, the opening start time is the same, but the opening completion time may be different depending on the size of the movable door 220, etc. Similarly, when the movable doors 220 of a plurality of screen door modules 200 are opened and closed at the same time, the closing start time is the same, but the closing completion time may be different depending on the size of the movable door 220, etc.

If the opening completion time of the movable door 220 is different, there is no problem with the safety of the passenger boarding and alighting process. However, if the closing completion time of the movable door 220 is different, a safety accident may occur during the boarding and disembarking process of the last passenger getting on and off. Not only does this have the potential to cause problems, but it can also cause problems such as increased instability in train departure signals and delayed departures.

To solve this problem, in one embodiment of the present invention, when the movable door 220 of the screen door module 200 is operated to close in an open state, the movable door 220 of the entire screen door module 200 The operation of the movable doors 220 of some screen door modules 200 may be controlled so that the closing operation start time is delayed for a certain period of time so that the closing operation completion time points are the same for all screen door modules 200 .

For example, when the opening width of the entrance 201 is relatively small and the operating distance of the movable door 220 is relatively short, the operation of the movable door 220 is controlled so that the start of the closing operation is delayed for a certain time. It can be.
