Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to platform safety fences and platform fences provided to prevent passengers from falling at platforms for straddle-type Morle vehicle type stations and Shinkansen passing stations. In particular, the present invention relates to a platform safety device that performs unmanned operation of the platform door station.

[Technical background of the invention]

This type of platform safety device that has already been proposed has several side-swinging double-opening doors installed on the platform at positions that correspond to the train stop position of the platform safety fence, and also has a mechanism for retracting the doors when the doors are opened. Door boxes are installed on both sides of the door and fixed to the platform safety fence. This door
Inside the box, there is a rail and roller device that supports the door and helps smooth opening and closing, an air cylinder door engine that drives the door opening and closing, and various equipment and air that controls the compressed air that is the power source for the door engine. A conduit is provided, and a light switch is installed on the door to prevent passengers from being caught. In addition, there are air systems for compressed air generation in other areas of the station.
We are equipped with the compressor, surrounding air equipment, electric motor for driving the air compressor, and its control equipment. A separate device is provided to automatically control the timing of opening and closing the door. Such previously proposed platform door devices are constructed as shown in FIGS. 7 to 12.

Figure 7 shows a cross section of an island-type stop for the straddle-type morrail. In the figure, 1 is the road, 2 is the station support, 3 is the station barrel, 4 is the concourse, 5 is the track laying surface, 6 is the platform, and 7 is the roof of the station. In general, a straddle-type mole rail station is a bridge station, and the station body 3 is supported by station supports 2 while keeping the building limits above the road 1. The orifice is roughly divided into a concourse 4 and a platform 6. A track installation surface 5 is formed outside the ceiling of the concourse 4, and a roof 7 is attached above the platform 6. Further, on the track installation surface 5, a track girder (molar rail) 8 having a single-shaped cross section is supported by a support 8a.
The train 9 runs astride the track girder 8.

Therefore, the difference in height between the platform 6 and the track installation surface 5 is approximately 2.8 m in the case of a straddle-type mole rail.

Also, there is a platform safety device on the platform 6! 110 is provided to prevent passengers from falling off the platform.

8 to 10 show the detailed structure of the home safety device 10. The platform safety device 10 is installed at a distance of 30cm to 50υ from the platform edge 6a at a straddle-type mole rail station, and 20α to 40α from the platform edge 6a, and at least 1m apart from the Shinkansen. This was done to avoid building restrictions that took into consideration wind pressure from trains and people coming into contact with trains. Platform safety equipment [10 is platform safety fence 11 and platform door 12. A door box 13 is installed around the station platform 6, and the platform door 12 is provided in accordance with the position of the train door when the train stops at a fixed position, and its opening size is the same as in the case of a straddle type mole rail. Vehicle door opening size is 1800-2000 compared to 1300IIR
It is al11. The platform safety tank 11 is generally composed of square or round steel pipes, assembled into a lattice with an outer frame 11a, columns 11b, side rails 11b, and fixed to the platform 6 by columns and safety fence foundations 11e. has been done. Home! A hanger roller device 12a and a lower guide roller device 12b are attached to the 12, which are fitted into an upper guide rail 13b and a lower guide rail 13C installed in the door box 13, so that the home holder 12 is laterally pulled along these. It is now possible to do so. A tension fitting 12 is attached to the hanger roller device 12a.
c is fixed and its tip is a pneumatic door engine 14a.
installed on. The door engine 14a is supported by 13
d to the door box 13, and the air pipe 1
4d communicates with a manual cock 140 for opening and closing the solenoid valve 202m. These are housed in a door box 13, and the door box 13 is covered with a cover 13a to protect internal equipment and prevent danger to people. The manual cock 14c inside the door box 13 is communicated with a compressed air generator (not shown) provided outside the door box 13.

In addition, the door box 13 is the outer frame 1 of the platform safety fence 11.
1a, a support 11b, a horizontal fence 11d, and a platform 6.

Further, a plurality of optical switches (photo-electrical switches) 12d are attached to the tip of the platform frame 12 to detect people, objects, etc. and prevent them from getting caught.

FIGS. 11 and 12 show a conventionally proposed control device near a home.

That is, a platform door opening/closing control device [18 provided at an appropriate location in the station is electrically connected to a buzzer 19, a solenoid valve 20, a light switch 12d, and a manual switch 18a for closing rnW@. As shown in the flowchart of FIG. 12, the door opening/closing control device 18 confirms that the train has entered the platform and stopped at a fixed position by interlocking with the information transmission device (not shown), and before the train door opens. The buzzer 19 is automatically sounded to open the platform door 12, and the buzzer 19 is automatically sounded to open the platform door 12 after the driver confirms that passengers have boarded and exited the train and closed the train door. In addition, if there is a person or object on the opening/closing line of the platform r112, the optical switch 12d detects it and automatically stops and restarts the closing of the platform door 12, or the central control center or train stop The platform door 12 is opened and closed in a timely manner by controlling the operation of the TRA valve 20 by manually operating a switch 18a provided on the platform 6 near the driver's seat.

[Problems with background technology]

However, the platform safety device 10 described above has a platform safety fence 11. Door box 13. Each platform has a different structure, such as the platform door 12, which is wrapped around the platform, giving it a different appearance and Ill! Not good either. Also, since it is a sliding door type, there is a risk of people's fingers getting caught. Furthermore, there is enough space for a person to stand between the platform safety device 10 and the platform edge 6a, so if someone leaves the train unloaded or intentionally steps out of the way, there is no station equipment on the station platform. Although dispatchers have discovered the danger through monitoring at the central command center and are making efforts to eliminate the danger by using public announcements within the station, they are unable to take action if the train crew overlooks the situation when the train is approaching the station or when the train is departing. It is extremely dangerous.

In particular, in the recent new transportation systems, including Morrail, in order to improve profits through labor savings, train crews are now operated by the driver alone without assistants or conductors, and station equipment has been eliminated to make stations unmanned. has been done. For this reason, there are cases where the entire platform is surrounded by glass to create a room, but this increases the construction cost considerably and requires a large amount of operating expenses such as the need for an air conditioner because of the enclosure, which offsets the labor-saving effect. Therefore, it is desired to develop a home safety device that is cheaper and safer.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and its purpose is to provide a station platform that is highly safe, and that also has a simple configuration that improves the scenery and reduces costs. The goal is to provide a safe place.

[Summary of the invention]

That is, in order to achieve the above object, the present invention is applicable to one-man train operation or unmanned station system, as well as straddle-type mole 1-ru stations and Shinkansen stations where there is a large drop between the station platform surface and the track laying surface. On platforms at stations where trains pass, in order to ensure safety on the station platform, the platform doors are designed to open and close by 90 degrees to prevent people from entering the railings, and when the doors open, there is a passageway to the railings. In addition, a detection operation is installed in the operating range of the railing and the platform door, and if a person or object is present there, an automatic room announcement means is used to broadcast guidance to guide passengers, and an alarm is issued. A control means is provided to prevent the platform door from opening and closing, and when the detection device detects the above, the train driver is notified of the occurrence of an abnormality on the platform to prevent an accident.
By making the home gate into a double-door shape, the platform safety device will be simplified and the scenery will be improved.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

It should be noted that the present invention will be described with the same reference numerals given to the same constituent members as those of the specific example of the conventional system described above. FIGS. 1 to 6 are diagrams showing embodiments of the present invention, and a straddle-type Morrail station will be described here. FIG. 1 is an overall view, FIG. 2 is a plan view showing the configuration near the front of the platform, FIG. 3 is a side sectional view as seen from six directions, and FIG. 4 is a configuration diagram of the control system. The platform safety fence 11 is fixed around the platform 6 by a safety fence foundation 11e at a distance from the platform edge 6a to avoid building limits, as in the conventional scheme. An opening 11p is provided at the platform safety fence 11 at the train door position when the train is stopped, with a width greater than the opening width of the train door 9a and greater than the accuracy with which the train stops in a fixed position, similar to the platform of a straddle-type mole 1-ru station. home end 6
If the distance from a to the platform safety fence 11 is relatively small, as shown in Figure 2, the platform safety fence 11 is bent toward the inside of the platform and used as a guide shelf 21 to prevent passengers from disturbing the line of people and cutting in from the side. do. In addition, from the platform safety tank 11 to the guide shelf 2
A door stopper 25 is provided on the platform door 22 side of the support column 11b at the point where it bends to 1 to prevent damage to the door. For platforms where the distance from the platform edge 6a to the platform safety fence 11 is relatively large, such as the platform of a Shinkansen train passing station, the fifth
As shown in the drawings and FIG. 6, the platform safety fence 11 is parallel to the platform end 6a, and the end thereof is fixed to the platforms by support columns aab and safety fence foundations 11e. Note that FIG. 5 is a plan view, and the sixth factor is a front view.

The platform door 22 according to the present invention has a configuration similar to that of the platform safety fence 11, and is constructed by combining a platform door outer frame 22a, pillars 22b, fence 22C9 and horizontal rails 22d in a grid pattern. At the middle upper part of the vinegar column 22b of this home vinegar 22, there is provided a columnar column part 22e which is narrowly constricted in a cylindrical shape to serve as the core of the hinge 23, and the hinge has a bearing 23a inside and can be divided into two parts. 23 to hold the columnar column portion 22e, thereby rotatably fixing it to the column 11b of the platform guide column 21. When the platform vinegar 22 rotates to open and close in the direction toward the platform track, it moves smoothly.

In addition, the lower part of the leg support 22b has a shaft protruding downward to support the load of the platform 22 and serve as a rotational axis for the door/engine installation [2].
A door support shaft 22f is attached to the door supporting shaft 22f, which is capable of transmitting the rotational driving force from 4 to the platform r#22. home! n22 is a door installed embedded in platform 6.
The door support shaft 22f is assembled into the engine IIf24, and the door engine @124 operates to open and close the door by rotating 90 degrees so that it closes when parallel to the platform end 6a and opens when it is perpendicular to the platform end 6a. Furthermore, this platform 1122 uses two sets of doors for passengers to get on and off the train, so that when the doors are closed, the gap between the doors is left open to the extent that a child can easily pass through. This is to prevent a major accident from occurring even if you get caught. Also, when the door is opened, the tip of the platform fi 22 is prevented from protruding beyond the platform end 6a to prevent contact with the row I9,
Furthermore, the gap between the train 9 and the end of the platform n22 is set to such an extent that a child cannot pass through and handle it, so that people are not pushed into the outside of the platform safety shelf 11 due to crowding. Even if the platform doors 22 are single-opened as a set in the door section for boarding and alighting train crew, the area around them will not be crowded, and the crew will not accidentally exit outside the platform safety fence 11 when boarding or alighting. no problem. As for the structure of the door engine system @24, three types, electric type, hydraulic type, and pneumatic type, have already been widely used in practical use, so the structure will not be specifically explained here. The door/engine unit [24] is attached to the floor surface around the horizontal leg support shaft 22f to prevent dirt from the platform 6 surface from entering inside.

A detection device 2G is provided on the floor surface in and around the area where the platform door 22 of the platform 6 opens and closes, and is electrically connected to the door opening/closing control device 18, the automatic broadcasting device 29, and the information transmission device 30a, The optical switch 12d used in the conventional example is removed from platform r#22.

This automatic broadcasting device 29 is connected to a speaker 29a and has a function of automatically broadcasting to the station premises, or manually broadcasting or interrupting broadcasting from a central command center. Information transmission equipment @ 3
0a is connected to a central command device 31 of a central command center, and further connected to an information transmission loop 32 installed near the train route via an information transmission device 30b. Information transmission loop 3
2 and the train 9 receive and receive signals via the information transmission antenna 9b and the on-board information transmission device 30c, and perform automatic operation of the train 9, display warnings to the driver, broadcast in the train, etc. . Meanwhile, the central command unit! A separate wireless telephone is installed between 31 and train 9, and a wireless antenna 31a at the central command center is installed.
It is possible to communicate with the central dispatcher 31m on the driving floor of the train 9 via the train's radio antenna 9C and a radio telephone device (not shown).

Detection devices 21 and 28 are provided on the floor of the platform 6 between the platform safety fence 11 and the platform end 6a, and on the track installation surface 5 (under the platform), respectively, and both are electrically connected to the automatic broadcasting device 29 and information It is connected to the transmission device 30a to form a communication network similar to that described above. As in the conventional example, the door opening/closing control device 18 is connected to a buzzer 19 and a door engine controller 20a such as a solenoid valve in the case of a pneumatic or hydraulic door engine, or a relay or a contactor in the case of an electric door engine. Detection device W126.
27 and 28 are mud switch type here, but other commonly used types such as radar type, heat wire type, ceiling switch type, or light beam switch type will not affect the function.

Detection device 26. The output of ~28 is the activation of the automatic broadcasting device 29 and the door opening/closing control device! f18 door open command, central command device 3
The central command device 31 is used for alarming the detection device 26.1. An alarm is output to the train 9 while receiving the outputs from 28 to 28. In addition, 18.18a, 19.20a, and 26 are made to correspond to each home vinegar, and 27.28 is provided along the longitudinal direction of the platform, respectively.

The above is an example targeting a Morrail station, but the platform edge 6a is similar to the platform at a Shinkansen train passing station.
FIG. 5 shows a platform door device in a case where the distance between the platform safety fence 11 and the platform safety fence 11 is relatively large, and the train door 9d is single-sided and its opening width is relatively narrow.

This will be explained using FIG.

FIG. 5 is a plan view of the main part, and FIG. 6 is a front view.

33 in the figure is a platform door, and this platform door 33 is a folding door type door that rotates 90 degrees and has a width that is approximately twice as wide when it is open as it is when it is closed. There is a hinge 33b in the center of the width direction of the door in the open state so that the vinegar can be folded, and a door guide device is installed on the floor of the lower platform 6 of the door in the open state. 33a
is attached so that the platform door 33 can be folded smoothly when it is closed. Note that the other structures have the same structure as the device of the present invention described above, so explanations are omitted, but by using this type of door, the opening of the platform safety fence 11 is narrow and the platform edge 6a and the platform safety Even when the distance between the fences 11 is wide, the same structure as in the previous embodiment is achieved.

This device with such a configuration can be used at straddle-type Morseal stations where there is a large drop between the station platform surface and the starting installation surface, Shinkansen train passing stations where there is a risk of people being blown away by wind pressure from passing trains, and In a transportation system that employs one-man operation of trains or an unmanned station system, a platform safety fence 11 is placed around the entire circumference of the station platform, and the train door 9 is placed in line with the position of the train door 9a when the train stops at a fixed position.
An opening 11p fi- of the platform safety fence 11 is provided with a width wider than the opening width of a, and the width is wider than the accuracy of stopping the train in a fixed position, and the platform safety fence 111 is bent in an L shape toward the inside of the platform to form the guide column 21. ing. Therefore, this guide column 21 can prevent passengers on the platform from disturbing the line and cutting in from the side when boarding the train. In addition, platform safety fence 1
The opening 11p of No. 1 has an opening 9 that rotates toward the platform end 6a side.
A platform fP22 of a 0° rotation opening/closing type is provided, and when this is parallel to the platform edge 6a, it can be used as a gap between the doors to prevent people from easily stepping out from the railing and falling from the platform. Also,
When the door is perpendicular to the platform edge 6a, the door is open and serves as a guide handrail for people getting on and off the train 9, and this guide handrail can prevent people from being pushed into the gap between the platform safety fence 11 and the train 9. Therefore, platform safety fence 11 and train 9
This prevents people from being pushed into the gaps between the containers, leaving them unloaded, and putting them at risk. If a person or object is placed in the opening/closing range of platform W#22 or in the vicinity, the platform door 2
A detection device 26 is installed as a device to detect that the platform 2 cannot be opened or closed, and a detection device 26 is installed between the platform safety fence 11 and the platform edge 6a and on the track installation surface 5 (under the platform). Detection devices 27 and 28 are installed to detect when a person is pushed into or falls into, or when a person or object is intentionally placed or thrown into the space.

Furthermore, the platform 1122 is opened and closed as before when the train 9 stops at a fixed position, the buzzer 19 sounds, and the train door 9a opens, and when the train 9 departs, the train door 9a is closed. The switch 18 is automatically controlled by a door opening/closing control device 18 to close the door after the train has stopped, and is installed at the central command center or on the platform near the driver's seat when the train is stopped.
Although it is the same as the conventional method in that it can be opened and closed manually by operation a, the detection device 26 is connected to the door opening/closing control IT device 118 and an automatic broadcasting device @28 is added.
For example, if a passenger arrives late and misses the train 9 because the train door 9a is closed, he or she may collide with the platform door 22 or leave the platform door 22 open. Train 9 can be prevented from departing. That is, in this case, since the passenger who missed the ride is on the detection device W126, the detection device 26 operates to detect the person. This detection signal is sent to the door opening/closing control device 18, and the door opening/closing control device 18 instructs the door engine controller 20a to open. Therefore, the platform door 22 remains open. At the same time, the output of the detection device 26 is also given to the automatic broadcasting device 29, so the automatic broadcasting device 29 operates and broadcasts a warning, for example, ``This is dangerous, so please return to the area.''

Since the output of the rough detection device [26] is also given to the information transmission device 30a, this information transmission device WI30a transmits the output to the central command device 31.

As a result, an alarm is displayed on the central command device 31 (for example, a buzzer sounds, a warning light lights up, etc.).

Therefore, the central dispatcher 31m of the central command center detects the occurrence of a dangerous situation by this alarm, and although it is not shown, the central dispatcher 31m of the central command center
View the monitor/TV within 1. The situation on the platform is displayed as an image on this monitor/TV, and the central dispatcher 31m can know the situation from this image. A warning within the train 9 is sent from the central transmission device 31 via the information transmission device 30b and the information transmission loop 32, and the warning is displayed in the driver's cabin within the train 9. When the driver sees this warning display, he cancels the immediate departure of train 9, and either waits for a while or looks out the window to confirm the situation. If you cannot make a decision due to visibility, return to the driver's seat to wait for instructions from central dispatcher 31m. When the passenger who missed the train returns to the train according to the guidance announcement, the output of the detection device @26 disappears, the platform door 22 closes, the alarm from the central command unit 31 disappears, and the alarm display inside the train 9 also disappears.

Then, since there is no warning from the central command center side, the central command staff 317FL takes no action and the driver also causes the train 9 to depart. In the unlikely event that the passenger collapses and cannot move, or does not evacuate, the abnormality can be detected on the monitors and televisions at the central command center, and in this case, the driver of train 9 can be contacted via radio telephone to request that the train not depart. and issue instructions for rescue and other countermeasures.

On the other hand, if there is a person or object between the platform safety fence 11 and the platform edge 6a, or if a person falls onto the track installation surface 5 (below the platform) and is in danger, the detection devices 27 and 28 are activated. Then, the detection output is sent to the automatic broadcasting device 29 and the information transmission device 30a, so the automatic broadcasting device 29 automatically broadcasts a warning message saying, ``This is dangerous, please return to the platform.'' , central command device 31
A warning will be displayed.

The alarm is sent to train 9 by the information transmission device 300, and train 9 detects that there is an abnormality and central dispatcher 31m
At the central command center, the central command staff 31m detects the occurrence of an abnormality in the same way as when detected by the detection device 26, watches the monitor/TV, and only if there is a real danger, sends a message to the relevant platform by radio telephone. 6, the driver of the train coming into the line is given instructions to slow down or make a sudden stop, and the driver of the train about to depart is given instructions to cancel the departure.

In this way, safety and reliability are improved by making it possible to avoid structural danger, and by waiting for the function to detect the presence of people or objects on the platform or track installation surface and notify abnormalities. In addition, by making the platform door double-door and incorporating the door/engine system @24 into the platform 6, the shape of the station platform safety device can be simplified and *tU can be improved.

〔Effect of the invention〕

As described in detail above, according to the present invention, it is possible to provide a platform safety device that has features such as high safety, improved scenery, and simple structure.
