Referring to the accompanying drawings, a preferred embodiment of the present invention,

The present invention, in the apparatus for washing the lower body (2) of the railway vehicle 1, it can be made largely comprising a side shielding means 110, washing water spraying means 120 and foreign matter collecting means 130. .

As a basic structure for washing the lower body 2 of the vehicle that proceeds first, an access road 3 provided with a rail through which the vehicle can proceed is provided, and the side shielding means 110 are installed on both sides of the access road 3. do.

The side shielding means 110 is to prevent the foreign body of the lower body (2) to move toward the outer surface of the upper carriage 4 by shielding the lower body (2) of the vehicle in progress to separate the carriage (4), The side shielding means 110 is arranged long in the traveling direction of the vehicle, as shown in FIG.

When the vehicle enters, the side shielding means 110 is installed to be in close contact with both sides of the vehicle, and moves along the vehicle traveling direction in a caterpillar form by the driving force of the vehicle.

That is, when the side shielding means 110 is in close contact with the entering vehicle, the side shielding means 110 naturally moves toward the traveling direction along with the vehicle while maintaining the close contact state. The side shielding means 110 is made of a soft synthetic resin having excellent adhesion. It is preferably made, and is supported by a plurality of idlers 111 to be moved by the vehicle in the form of a caterpillar.

Therefore, no close slip occurs between the side shielding means 110 and the vehicle 1, and thus a close state is maintained, so that the vehicle is not damaged or scratched by the side shielding means 110 while the vehicle is in progress.

Here, the side shielding means 110 is to prevent the foreign matter of the lower body 2 to move toward the upper carriage 4, the point where the side shielding means 110 in contact with the vehicle is a vehicle carriage 4 ) And the lower body 2 are suitable.

That is, if the boundary point between the carriage 4 and the lower body 2 is completely shielded, foreign matters of the lower body 2 cannot rise to the upper part of the vehicle at least through the side of the vehicle.

In addition, in another embodiment, the side shielding means 110 may be configured to be in close contact with the entire side of the carriage 4, except for the lower body (2) of the vehicle.

When the side shielding means 110 is in close contact with the entire side of the carriage (4) it is possible to prevent the foreign matter that is separated from the lower body (2) to stick to the side of the carriage (4) in advance.

On the other hand, the washing water spraying means 120 is installed on the access road 3 corresponding to the lower portion of the side shielding means 110, the washing water spraying means 120 is the lower body (2) of the railway vehicle (1) Spray the wash toward the bottom of the vehicle to be cleaned.

The washing water spraying means 120 is sufficient if it is installed in a suitable place on the path that the vehicle proceeds, there can be a variety of kinds of washing water sprayed, according to an embodiment of the present invention may be compressed air used as the washing water.

That is, when compressed air is injected at a predetermined pressure toward the vehicle lower body 2, foreign matter adhering to the lower body 2 is separated from the lower body 2.

Here, the washing water spraying means 120 using the compressed air as the washing water may include a compressor for compressing air and an injection nozzle stage for spraying high pressure air compressed by the compressor.

However, as described above, using compressed air as a cleaning material may have an effect on dropping foreign matters with low adhesion from the body, but they have been attached for a long time and have been mixed with oil and fixed to the lower body 2. Compressed air alone is not enough to eliminate this problem.

Therefore, in another embodiment of the present invention, the washing water spraying means 120 may be sprayed at a predetermined pressure by using a sublimable substance as the washing water.

When the washing water spraying means 120 injects a sublimable material, the sublimable material is sprayed in a solid state having fine particles, so that foreign matters are dropped while colliding with the lower body 2, so that the impact force is larger than that of compressed air, thereby removing foreign matters. The effect is high.

In addition, since the sublimation immediately after removing the foreign matter in the gaseous state does not remain in various parts or electrical devices of the lower body 2, various kinds of solid particles may be caused by remaining in the lower body 2 of the vehicle Malfunction or failure of the device can be prevented.

Here, there may be a variety of the sublimable material, although dry ice is used in the practice of the present invention, it is not necessarily limited thereto.

On the other hand, the foreign matter collecting means 130 for collecting the foreign matter separated from the vehicle by the washing water spraying means 120 is provided, the foreign matter collecting means 130 is the lower body by the washing water spraying means 120 It is preferable to be disposed around the vehicle so as to effectively inhale and collect the scattering foreign matter separated from (2).

Therefore, since the foreign matter collecting means 130 will have the most foreign matter scattered on the lower body 2, it is preferable that a plurality of the foreign matter collecting means 130 is disposed on the lower body 2 side (for example, the access road 3) of the vehicle.

Since foreign matters scattered from the vehicle lower body 2 side are collected by the foreign substance collecting means 130 because they are blocked from moving toward the upper side of the passenger car 4 by the side shielding means 110, the vehicle lower body (2) Since the front and rear of the side is open, foreign matter can flow out through this.

In order to prevent the scattered foreign matters from coming out toward the front and rear of the vehicle lower body 2 side, the air is sprayed in the form of a film to the access path 3 corresponding to the front and rear of the vehicle lower body 2 side. It is preferable that the air curtain part 140 forming the blocking film is additionally installed.

When the high-pressure air is sprayed in the form of a film toward the upper portion of the vehicle lower body 2 from the air curtain unit 140, an invisible air barrier film is formed and the scattering dust is blocked by the air barrier film so that the vehicle lower body 2 Cannot come forward and backward.

As such, blocking the front and rear of the vehicle with an air barrier prevents a collision with the protrusion 5 when the vehicle progresses due to the protrusion 5 such as a wheel or an electric accessory on the lower body 2 of the vehicle. For example, it is possible to form an air barrier film that may not collide with other structures for sealing.

However, the lower body 2 of the vehicle has various protrusions 5 as described above, and even if an air barrier film is formed by the air curtain part 140, the air barrier film is released by the protrusions 5 to completely block it. This is a difficult problem.

Accordingly, in the present invention, in order to solve this problem, the air formed by the air curtain part 140 is provided by arranging the flap part 150 corresponding to the structure of the protrusion 5 and surrounding the air curtain part 140. Allow the barrier to remain unreleased.

That is, the flap unit 150 has a function of inducing air from the air curtain unit 140 to reach every corner of the vehicle lower body 2, and to the protrusion 5 of the vehicle lower body 2. It extends close enough to more effectively block flying objects from moving forward and backward.

In this case, the flap unit 150 is preferably rotatably installed so as to be folded when collided with the protrusion 5 of the lower part of the vehicle in case of colliding with the protrusion 5.

As described above, when the vehicle lower body 2 is shielded from the side, and both the front and the rear of the vehicle, foreign substances are collected, but the side shielding means 110 continuously moves as shown in FIG. 2. Since it is made in the form of a caterpillar, a gap is inevitably formed at both ends of the side shielding means 110, and foreign substances scattered by the gap are raised to come out of the front and rear of the vehicle.

Therefore, the secondary shielding means 160 is added to both ends of the side shielding means 110 to fill the gap generated between the vehicle and the side shielding means 110 to prevent foreign matter from being ejected toward the front or the rear of the vehicle. It is preferable to be installed as.

The auxiliary shielding means 160 may be formed in a round rod shape as shown in FIG. 2, and is installed to be rotated (rotated) in place by a traveling vehicle.

That is, the auxiliary shielding means 160 is also in close contact with the traveling vehicle, and is rotated by the driving force of the vehicle to prevent foreign substances raised into the gap of the side shielding means 110 is ejected to the front and rear of the vehicle.

Here, the auxiliary shielding means 160 may be formed to have a height corresponding to the height of the passenger car 4 of the vehicle, and is preferably made of a soft synthetic resin material so as not to damage or scratch the vehicle even when the auxiliary shielding means 160 is in close contact with the vehicle.

On the other hand, the foreign body scattered even in the state that the vehicle lower body 2 is all closed as shown in Figure 1 can rise on the roof of the vehicle through the gap formed in the connection portion (4a) between the carriages 4, the roof In order to prevent the foreign matters that are raised up from scattering around, it is preferable that the scattering prevention unit 170 is additionally installed.

The scattering prevention unit 170 is a structure that allows a predetermined space to be formed on the roof of the vehicle while surrounding the vehicle, and prevents foreign matter, especially dust, which has risen on the roof of the vehicle from spreading around to prevent workers or people from respiratory diseases. To prevent it.

Here, the shatterproof portion 170 is sufficient if a predetermined space is formed on the roof of the vehicle, but may extend to cover the carriage 4 while wrapping the vehicle as illustrated in FIG. 1. However, at this time, the shatterproof portion 170 and the vehicle may be a predetermined gap so as not to contact each other.

In addition, the scattering prevention unit 170 is preferably provided with a foreign matter collecting means 130 for collecting the foreign matter raised through the gap between the connection between the carriage (4).

According to the drawings attached to the present invention, the foreign matter collecting means 130 of the scattering prevention unit 170 is illustrated as being installed on the ceiling, but the position is not necessarily limited to the drawings and may be a most suitable position for collecting foreign matter.

On the other hand, it is preferable that the air curtain portion 140 for preventing the scattered foreign matter is discharged to the front and rear of the scattering prevention portion 170 also in front and rear of the scattering prevention portion 170.

If the railway vehicle 1 to be cleaned is a general vehicle without a pantograph, a separate structure may be installed in place of the air curtain unit 140, but in the present invention, the general railway vehicle 1 as well as the electric vehicle may be installed. As such, the air curtain part 140 may be installed on the scattering prevention part 170 so that the pantograph 6 may be easily used.

In addition, the air curtain unit 140 may be installed on both sides of the scattering prevention unit 170 so that the air barrier layer is formed.

Of course, it is preferable that the flap unit 150 having a function as described above is rotatably installed around the air curtain unit 140 of the scattering prevention unit 170 so as to form the air barrier layer more effectively.
