Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a method for cleaning the rear surface, side surfaces, shoulders, roof surface, and connecting surfaces, that is, the entire surface of a vehicle.

[0002]

2. Description of the Related Art As a conventional railway vehicle cleaning device, a cleaning device for cleaning a side surface of a vehicle as disclosed in Japanese Patent Laid-Open No. 2-249745, and Japanese Patent No. 1565085.
There is known a cleaning device for cleaning the front and rear surfaces of a vehicle, which is disclosed in Japanese Utility Model Publication No. Hei 2-132567.

The conventional cleaning devices as described above are roughly classified into two types as described below as a method for cleaning a vehicle. (1) A method in which a cleaning device is installed and fixed on both sides of the track so as to face each other, the vehicle is allowed to enter between the cleaning devices at a low constant speed, and the outer surface of the vehicle body is cleaned as the vehicle moves. (2) A trolley that can run parallel to this track is arranged on both sides of the track, a cleaning device is mounted on the trolley, and the cleaning device is moved with respect to a vehicle stopped on the track. How to clean the outside surface of the vehicle.

[0004]

However, in each of the conventional cleaning methods described above, first, in the method (1), the vehicle is run at a constant speed and at a low speed of about 2 to 5 km / h. The cleaning method is premised on passing between cleaning devices. However, maintaining the traveling speed of the vehicle is also affected by the driver of the vehicle, and it is technically difficult to drive the vehicle at the low constant speed as described above, which is a big problem. In particular, when cleaning the front and rear surfaces of a vehicle, there is a drawback that a sufficient cleaning effect cannot be obtained at such a low constant speed.

Further, in the above method (2), guide rails capable of running the cleaning device must be laid on both sides of the vehicle track, and the equipment becomes large in size. There is a drawback that a sufficient cleaning effect cannot be obtained unless they are laid in parallel.

Due to these problems, despite the fact that various cleaning devices as described above have been devised, only the side surface of the vehicle body is cleaned by a mechanized cleaning device, and the front / rear surface and the connecting surface of the vehicle are cleaned. The current situation is that the cleaning is done manually, and the cleaning work of the vehicle is complicated.

[0007] In recent years, railroad vehicles have been formed into a streamlined shape in which the outer shape of the railroad vehicle, in particular, the leading vehicle has a curved surface, to reduce running resistance due to aerodynamic force. An intermediate vehicle connected to such a streamlined leading vehicle also has a curved outer surface from the roof to the side surface, and a glass window is formed on the shoulder or roof of the vehicle. Many types of vehicles have appeared, such as vehicles designed for landscape purposes.

However, the above-mentioned conventional cleaning device cannot sufficiently cope with such a new shape of the vehicle, and particularly the shape and contact angle of the rotating brush, such as the front and rear surfaces of the vehicle, cannot be coped with. There is a problem that it is difficult to clean unless a cleaning device with a different setting for each vehicle type is prepared and made compatible, that is, one cleaning device cannot support vehicles of different shapes, which makes it versatile. It has the drawback of being low. Further, since an overhead line for transmitting electric power to the vehicle is installed on the roof portion of the vehicle, there is a problem that the operator manually handles it.

In order to solve the above-mentioned problems, the present invention aims to reduce the labor required for washing the vehicle, and to protect the entire surface of the vehicle, such as the side and front / rear surfaces of the vehicle, the roof portion and the connecting surface between the vehicles. It is an object of the present invention to provide a method for cleaning the entire surface of a vehicle, which can be automatically cleaned and a sufficient cleaning effect can be obtained even for vehicles of different shapes.

[0010]

Means for achieving the above object will be described below with reference to FIGS. 1 and 2 corresponding to the embodiments. The method for cleaning the entire surface of a vehicle according to the present invention includes a plurality of rotating brushes 110 and 21 which are installed outside the building limit of the track vehicle A and can move back and forth with respect to the track L.
The vehicle A to be cleaned is conveyed between the cleaning devices 1 provided with 0, 310, 410, 510, and 610, and the entire surface of the outside of the vehicle A is cleaned by the plurality of rotating brushes. I am trying.

[0011]

The vehicle A to be cleaned is transported and the vehicle A is moved at a low constant speed. Then, the vehicle A is made to enter between the cleaning devices 1 installed outside the building limit of the track L, and the front surface Aa, the rear surface Ab, and the shoulder portion Ah of the vehicle A are moved by the plurality of rotating brushes provided in the cleaning device 1. The side surface Ad, the roof surface Ac, and the connection surface Ai are individually washed.

Although not shown in the figure, the cleaning device 1 is a chemical liquid cleaning device for applying a chemical liquid such as a detergent to the surface of each cleaning surface of the vehicle A as a pre-process for cleaning by this device, and a post-cleaning device. An air blower for sending a high-speed airflow to the vehicle A to blow away water droplets adhering to the surface of the vehicle A is attached.

Further, although not shown, a contact type sensor or a non-contact type sensor is provided in each of the above-mentioned transfer device T and cleaning device 1, and the shape of the vehicle A on the track L is determined. And the approach speed of the cleaning device 1 of the vehicle A, the presence or absence of the vehicle A, etc. are detected. Based on the signal of this sensor, the starting and braking of the transport device T and the operation of the cleaning device 1 are performed. A control device is provided to control the.

Next, the cleaning device 1 configured as described above.
A method of cleaning the vehicle A of the present invention using the transport device T will be described. The shape of the vehicle A to be cleaned will be described as a vehicle A of a formation in which a streamlined leading vehicle as shown in the drawing is connected.

First, for vehicle A, one of the trains
The wheels Aw of the vehicle are held by the transport device T. Then, it is conveyed at a low constant speed, for example, a constant low speed of 1 to 3 km / h, and moved between the cleaning devices 1. As described above, since the overhead line W is not installed on the track L on which the vehicle A to be washed moves, the vehicle A cannot be self-propelled because power is not transmitted, and the pantograph P of the vehicle A is folded. It is in a state of

In the cleaning device 1, the vehicle type (shape type) of the vehicle A, which is the object to be cleaned, is input to a control device (not shown) before the vehicle A enters between the cleaning devices 1. This input is made by detecting the vehicle shape by a sensor installed in the vicinity of the track, or by selecting the vehicle shape by operating a selection button by an operator.

Next, the control device sends a signal to the cleaning device 1, and each of the brush units 100 to 500 excluding the connecting surface brush unit 600 causes each rotary brush to project to the track L side based on the signal. Then, as described above, the brush units 100 to 500 perform cleaning as the vehicle A advances (see FIGS. 5 to 9).

With these brush units, the front surface Aa, the rear surface Ab, the roof surface Ac side surface Ad, the window Ae,
When the cleaning of the shoulder portion Ah is completed, the transport device T moves the vehicle A in the opposite direction, and when the connecting portion between the vehicles in the vehicle row approaches the connecting surface brush unit 600, the transport device T stops and the vehicle A Is stopped, and the coupling surface Ai of each vehicle A is washed, as shown in FIGS. When the cleaning is completed, the next connecting portion is moved to the position of the brush unit 600, and the above operation is repeated to clean each connecting surface Ai.

Therefore, in the method of cleaning the entire surface of the vehicle A thus constructed, since the vehicle A, which is the object to be cleaned, is moved by the transfer device T, power transmission from the overhead wire W is unnecessary. That is, in this embodiment, the overhead line W is provided above the vehicle A.
Since the rotary brush can clean the roof surface Ac of the vehicle A, the rotary brush can be moved further upward to avoid the pantograph P provided on the roof surface Ac. As a result, the vehicle A
It becomes possible to clean the entire front and rear surfaces, side surfaces, roof surface, etc., and it is possible to clean the vehicle A without cleaning manually. Further, since the vehicle A to be washed is moved by the transfer device T, the moving speed of the vehicle A can be freely changed, that is, the vehicle A is moved at a low constant moving speed that cannot be realized by the vehicle A self-propelled. Since it can be moved, it moves at the optimum speed for the vehicle A to be washed,
It is possible to perform cleaning, which allows cleaning to be performed without causing uneven cleaning effect.

In the above-described embodiment, an example in which the transporting device T including the transporting device 2 disposed between the rails of the track L and movable between the rails is used as the transporting means for the vehicle A on the track L. However, the transport means of the vehicle A is not limited to this. For example, the vehicle A as shown in FIG.
Using a small substantially vehicle-shaped carrier that can move on the same track as the track L of the vehicle
May be made to enter between the cleaning devices 1. In this case, it is desirable to use a device that does not rely on overhead lines, such as a carrier machine that uses a diesel engine as a power source, or a carrier machine that uses an apto-type drive that uses a rack rail. Alternatively, the vehicle A may be simply pulled by a wire or the like to enter between the cleaning devices 1.

Further, in the present embodiment, the example of the cleaning method in the case where the overhead line W for the vehicle A is not installed on the track L has been described, but it is also applicable to the section where the overhead line W is installed. Is. Also in this case, the operation of the horizontal brush unit 100 that moves the vehicle A by using a transfer device or the like that transfers the vehicle A on the track to wash the roof surface Ac of the vehicle A in the present embodiment is described. Front Aa and Rear Ab
The rotating brush 110 of the brush unit 100 may be controlled so as not to come into contact with the overhead wire W so that the brush unit 100 operates only by itself.

Further, in the present embodiment, an example in which the front and rear surfaces of the vehicle and the roof surface are made to correspond to each other by the pair of left and right horizontal brushes 110 and cleaned is described, but as shown in FIG.
Cleaning may be performed by a structure in which the rotating brush 710 horizontally provided above is moved up and down, or the rotating brush for cleaning the front and rear surfaces and the rotating brush for cleaning the roof surface may be separately configured. .

[0039]

As described above, in the method for cleaning the entire surface of the vehicle according to the present invention, since the vehicle to be cleaned is moved by the carrier device, the moving speed of the vehicle can be freely changed, that is, the vehicle itself can be changed. Since it is possible to move the vehicle at a low constant speed that cannot be achieved by running, it is possible to enter between the cleaning devices at the optimum speed for the vehicle to be cleaned, which makes it possible to clean each cleaning surface of the vehicle. There is an effect that cleaning can be performed without causing unevenness of effect.
Further, since the entire surface of the vehicle is configured to be cleaned by using a plurality of rotating brushes, there is an effect that cleaning can be performed corresponding to different types of vehicles having different outer shapes. That is, it is possible to reduce the labor required for cleaning the vehicle, and it is possible to automatically clean the entire surface of the vehicle, such as the side surfaces, front and rear surfaces of the vehicle, the roof part, and the connecting surfaces between the vehicles, so that different shapes can be used. There is an effect that a sufficient cleaning effect can be obtained even for a vehicle.
