Embodiment 1 FIG.
FIG. 1 is a perspective view showing a platform gap closing device according to Embodiment 1 of the present invention, FIG. 2 is a side view showing an essential part of the platform gap closing device according to Embodiment 1 of the present invention, and FIG. It is a figure which shows the structure of a board.

  1 to 3, reference numeral 1 denotes a station platform. A platform fence 2 is installed on the platform 1 along the end on the track (railway vehicle) side. The main part of the home fence 2 includes, for example, a general control fence 3, an individual fence 4 on the master side, an individual fence 5 on the slave side, and a home door 6.

7 is an integrated control panel built in the integrated control fence 3, and 8 is an individual control panel built in the individual fence 4 on the master side.
The general control panel 7 manages the control function of the entire home fence 2. For example, the general control panel 7 includes a home vehicle relay 9, a vehicle coupling relay 10, and a door closing detection relay 11.

The home vehicle relay 9 detects that the vehicle has entered the platform 1. That is, when the vehicle enters the platform 1, the home vehicle relay 9 is turned on.
The vehicle coupling relay 10 detects that the vehicle is at a predetermined stop position of the platform 1. That is, when the vehicle comes to the stop position and the vehicle door and the home door 6 are coupled, the vehicle coupling relay 10 is turned on.

  The door closing detection relay 11 detects that the home door 6 is closed. The home door 6 is normally in a door-closed state, and the door-close detection relay 11 is ON. A predetermined signal (door opening signal) for opening the home door 6 is transmitted from the railway vehicle. When a door open signal is transmitted from the railway vehicle, the home door 6 starts the door open operation, and the door close detection relay 11 is turned off. Further, when a predetermined signal (door closing signal) for closing the home door 6 is transmitted from the railway vehicle when the home door 6 is opened, the home door 6 starts the door closing operation. When the home door 6 is completely closed, the door closing detection relay 11 is turned on.

  The individual control panel 8 has a function of controlling the home door 6. The individual control panel 8 is provided corresponding to each set of the home doors 6 (the home door 6 housed in the master-side individual fence 4 and the home door 6 housed in the slave-side individual fence 5), for example. Yes. The individual control panel 8 includes a master-side interlock 12 and a slave-side interlock 13.

  The interlocks 12 and 13 are for preventing the home door 6 from opening and holding the home door 6 in the door-closed state. When the individual control panel 8 receives the door opening signal from the railcar, it releases the door opening prevention of the home door 6 by the interlocks 12 and 13. That is, the interlocks 12 and 13 are unlocked, and the opening operation of the home door 6 is started. Further, in the individual control panel 8, when the door closing signal is transmitted from the railway vehicle and the home door 6 is completely closed, the door 12 is prevented from being opened by the interlocks 12 and 13. That is, the interlocks 12 and 13 are locked, and the home door 6 is held in a closed state.

Reference numeral 14 denotes a closing device for closing a gap formed between the platform 1 and a stopped railway vehicle. The main part of the closing device 14 is constituted by, for example, a footboard 15, an interlock 16, an electromagnetic plunger 17, and an operation relay 18.
The closing device 14 is controlled by a tread board control panel 19. The tread board control panel 19 is provided below the platform 1, for example.

  The tread board 15 is for (partially) closing a gap formed between the end of the platform 1 on the track side and the vehicle when the railway vehicle stops on the platform 1. The foot board 15 is arrange | positioned corresponding to each opening of the home fence 2 formed when the home door 6 opens. The tread board 15 is supported by the platform 1 with a predetermined structure that can approach and separate from a railway vehicle stopped on the platform 1, for example. The tread plate 15 is movable between a predetermined storage position where the tip 15a does not protrude from the end of the platform 1 toward the track side and a predetermined protruding position where the tip 15a protrudes from the end of the platform 1 toward the track side. Composed. When the tread plate 15 is disposed at the protruding position, the tip 15a protrudes from the end of the platform 1 to the line side by about 100 mm, for example.

  The interlock 16 is for preventing the tread plate 15 from moving toward the track (moving to the protruding position) and holding the tread plate 15 in the storage position. Reference numeral 20 denotes a switch for detecting the operation of the interlock 16.

  The electromagnetic plunger 17 is for driving the tread plate 15. The operation relay 18 of the electromagnetic plunger 17 is normally ON, and the electromagnetic plunger 17 is excited. In a state where the electromagnetic plunger 17 is excited, the electromagnet attracts the tread plate 15 against the urging force of a spring or the like, and the tread plate 15 is disposed at the storage position.

  On the other hand, when the operation relay 18 is turned off, the electromagnetic plunger 17 is demagnetized. When the electromagnetic plunger 17 is demagnetized and the attraction force of the electromagnet disappears, the tread plate 15 is pushed by the urging force and moves to the line side. That is, the tread plate 15 is disposed at the protruding position by the electromagnetic plunger 17, and a gap formed between the track-side end of the platform 1 and the vehicle is closed by the tread plate 15.

  Next, the operation of the gap closing device having the above configuration will be described with reference to FIG. FIG. 4 is a flowchart showing the operation of the platform gap closing device according to Embodiment 1 of the present invention.

  When the railway vehicle enters the platform 1 (S1), the home vehicle relay 9 is turned on. Further, when the vehicle stops at the stop position and the vehicle door and the home door 6 are arranged at the opposing positions, the vehicle coupling relay 10 is turned on. Even if the vehicle stops at the coupling position with the home door 6, if no door open signal is transmitted from the vehicle, the home door 6 is in the door closed state and the door close detection relay 11 is ON (S3). , S4). For this reason, the interlock 12 of the individual fence 4, the interlock 13 of the individual fence 5, and the interlock 16 of the tread plate 15 are all ON (S 5, S 6), the electromagnetic plunger 17 is excited, and the tread plate 15 is stored. (S7).

  On the other hand, when a door open signal is input from the railway vehicle stopped on the platform 1 (S8), the individual control panel 8 unlocks the interlocks 12 and 13 (S9) and opens the home door 6. When the door opening operation of the home door 6 is started, the door closing detection relay 11 is turned OFF in the integrated control panel 7 (S10).

  When the interlocks 12 and 13 are unlocked, the tread board control panel 19 unlocks the interlock 16 of the tread board 15 (S11). In the tread board control panel 19, when the interlock 16 is unlocked, the operation relay 18 is turned OFF (S12), and the electromagnetic plunger 17 is demagnetized. That is, when the attraction force of the electromagnet disappears, the tread plate 15 is pushed by a biasing force such as a spring and moves to the track side, and the tread plate 15 is arranged at the protruding position (S13). As a result, the gap formed between the platform 1 and the vehicle is closed by the tread plate 15 while passengers are getting on and off.

  Thereafter, when a door closing signal is input from the vehicle (S14), the individual control panel 8 starts the door closing operation of the home door 6. In addition, when the door closing signal is input from the vehicle, the operation relay 18 is turned on in the footboard control panel 19 (S15). As a result, the electromagnetic plunger 17 is excited and an attractive force is generated in the electromagnet, and the electromagnet attracts the tread plate 15 against an urging force such as a spring (S16). That is, the tread plate 15 moves to the platform 1 side and is disposed at the storage position. Further, the tread plate 15 is disposed at the storage position, whereby locking by the interlock 16 is performed, and the tread plate 15 is fixed at the storage position (S17, S7).

  When the door closing of the home door 6 is completed, the individual control panel 8 turns on both the interlocks 12 and 13 to fix the home door 6 at the door closing position. When the door closing of the home door 6 is completed, the door closing detection relay 11 is turned on in the integrated control panel 7.

  With the gap closing device having the above-described configuration, the gap formed between the platform 1 and the stopped railway vehicle can be closed with a simple configuration using the electromagnetic plunger 17. For this reason, even if a passenger drops an object while getting on and off the vehicle, the tread board 15 can prevent the object from falling to the track. Moreover, since the gap formed between the platform 1 and the parked vehicle can be closed, passengers with reduced mobility and wheelchair users can easily move between the platform 1 and the vehicle. it can.

  In the present embodiment, the case where the unlocking of the interlock 16 and the demagnetization of the electromagnetic plunger 17 are performed on the condition that the interlocks 12 and 13 are unlocked has been described. However, this is merely an example, and the interlock 16 may be unlocked and the electromagnetic plunger 17 may be demagnetized based on other conditions.

For example, on the condition that the door closing detection relay 11 is turned off, that is, the door closing state of the home door 6 is not detected, the interlock 16 is unlocked and the electromagnetic plunger 17 is demagnetized. Also good.
Further, when a signal detection means for detecting a door open signal or a door close signal from the railway vehicle is provided, the unlocking of the interlock 16 is performed on condition that the door open signal is detected by the signal detection means. And demagnetization of the electromagnetic plunger 17 may be performed. In such a case, for example, when a door closing signal is detected by the signal detection means, the tread board control panel 19 turns on the operation relay 18 to excite the electromagnetic plunger 17. Then, when the tread board 15 is subsequently placed in the storage position, the interlock 16 is operated to fix the tread board 15 in the storage position.

  Even with such a configuration, it is possible to achieve the same effects as described above.
