The cutoff sockets 5, 6 are installed under the floor or outside the vehicle, and the three-way sockets 7, 8 are installed in the crew cabin. The compressed air from 4 can be led to the upstream side, and the upstream side can be opened to atmospheric pressure.

Under normal conditions, pressure fluid flows from the pipe line 4 to the pipe line 9,
Each is guided by 10. Door closing circuit A1-A
6 is provided with an electromagnetic switching valve that is manually controlled, and the side door is driven to open and close by the compressed air from the pipes 9 and 10 based on the control of the electromagnetic valve.

In such prior art, door closing circuits A1 to A6
When a failure occurs in the solenoid valve provided in the solenoid valve and the electrical configuration associated with the solenoid valve, or when the power supply is lost, the solenoid valve is operated by the spring force to close the conduits 9 and 1.
This is the operating position where compressed air from 0 is supplied in the direction of closing the side door. Therefore, in order to allow passengers to escape from each vehicle, the crew must operate the three-way cocks 7, 8 to open the pipes 9, 10 to atmospheric pressure.

Such three-way locks 7 and 8 are individually provided for each vehicle, and therefore, the three-way locks 7 and 8 are provided so that the side doors of each of the plurality of connected vehicles can be manually opened. , 8 while walking, which requires a great deal of effort, and this becomes a big problem, especially when an accident occurs in a long series of vehicles.

An object of the present invention is to provide an improved system that can simultaneously control all or at least some of the side doors provided on each vehicle in a connected train so that they can be opened manually. An object of the present invention is to provide a side door control device for a coupled vehicle.

The present invention provides that each of a plurality of connected vehicles has the following features:
Between the double-acting cylinder that opens and closes the side door and the operation switching valve, the pressure fluid source that supplies pressure fluid to the side door via the operation switching valve to drive the double-acting cylinder, and the operation switching valve and the pressure fluid source. The switching operation is performed by pilot pressure, and when there is no pilot pressure, the pressure fluid from the pressure fluid source is guided to the operating switching valve, and when there is pilot pressure, the upstream side of the operating switching valve is opened to low pressure. Equipped with a switching valve for all cars in the formation,
When the upstream side of the operation switching valve is opened to low pressure,
The side door is configured to be manually openable, and the pilot pressure of the switching valve for all cars in the formation is connected to a conduit common to all cars in the formation, and the pipe is connected to at least one of the pressure fluid sources.

The actuating position 109b is switched to, thereby closing the line 107 and opening the line 111 to the lower atmospheric pressure.

FIG. 4 is a pneumatic circuit diagram showing the principle of the door closing circuit A11. The door closing circuit A11 has a double-acting cylinder 121 for opening and closing the side door. A piston rod 123 of this double-acting cylinder 121 is connected to a side door. When compressed air is being supplied to the cylinder chamber 124 of the double-acting cylinder 121, the side door is closed. Conversely, when compressed air is being supplied to the other cylinder chamber 125, the side door is opened. The solenoid valve 126 as an operation switching valve is
It has two operating positions 127, 128 and is spring biased.

When the solenoid valve 126 is not energized, compressed air is led from the line 111 to the cylinder output 124 via the operating position 127 and the side door is closed. At this time, the cylinder chamber 125 is open to atmospheric pressure. When the solenoid valve 126 is energized, it is switched to the operating position 128, whereby the compressed air from the conduit 111 is guided into the cylinder chamber 125 and the side door is opened. At this time, the cylinder chamber 124 is open to atmospheric pressure. Remaining door closing circuits A12, A1

In the door closing circuit A11, the solenoid valve 126 shown in FIG.
The solenoid valve 126 is in the actuated position 127 when the associated electrical components fail or power is lost. As a result, the cylinder chamber 124 is connected to the pipe line 11.
1 becomes conductive. Vehicles C1, C2, C3
In order for passengers to escape from the train, they operate the three-way cock 114 provided in the crew cabin 11 to fill compressed air into the conduit 401 on one side, and the changeover valve 109 for all cars in the train sets to the operating position 109b. Conduit 11
1 is opened to the atmosphere. Therefore, cylinder chamber 1
24 becomes atmospheric pressure. Another cylinder chamber 12
5 is already open to atmospheric pressure by means of the actuation position 127 of the solenoid valve 126. In this way, the piston rod 123 of the double-acting cylinder 121 becomes movable, making it possible to manually open the side door. This means that the remaining door closing circuits A12, A13; A21,
The same applies to A22, A23; A31, A32, and A33.

As another embodiment of the present invention, the pilot ports of the switching valves 110, 210, 310 for all cars in the train are commonly connected to the pipe line 401, and the three-way valves 114, 3
All the side doors of all the vehicles C1, C2, and C3 may be manually opened/closed by the operation in step 14.
At this time, the three-way pot 115, 315 and the pipe 4
02 is omitted.

In the illustrated embodiment described above, although the conduit 401 is configured to be able to be supplied with compressed air from the vehicles C1 and C3, one of the vehicles C1
Compressed air is supplied from the pipe line 104 through the three-way tank 114, and at this time, the three-way tank 31
4 may be omitted. This also applies to the conduit 402.

As described above, according to the present invention, it is possible to simultaneously control all or at least some of the side doors of a plurality of connected vehicles so that they can be manually opened. Become. Further, according to the present invention, safety in an emergency is improved, it can be handled as before, it can be easily applied to conventional vehicles, and it becomes possible to operate as a one-man operation without the need for a conductor.
