It is related to the equipment used.

[Prior Art] As a conventional method of cleaning a rail vehicle, a method of cleaning only with fresh water as the vehicle advances is often used.

[Problems to be Solved by the Invention] In the case of clean water cleaning, the cleaning brush in front of the vehicle in the direction of travel is likely to become contaminated, and after a considerable period of time, there is a feeling that the contamination will actually adhere to the vehicle. Accordingly, cleaning of the cleaning brush itself is required.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method for cleaning a rail vehicle that can prevent the progress of contamination of the cleaning brush in front of the vehicle in the direction of travel when clean water cleaning is performed continuously. A further object of the present invention is to provide a cleaning device for a rail vehicle that is used in the method and prevents the progress of contamination of cleaning brushes.

[Means for Solving the Problems] In order to achieve the above object, the method for cleaning a rail vehicle of the present invention includes spraying clean water onto the vehicle and cleaning the vehicle with clean water using a rotating brush, and maintaining the clean water cleaning state. When it is detected that the washing has continued for a predetermined number of times or for a predetermined period of time, the cleaning water is mixed with the clean water manually or automatically, and the mixed cleaning water is sprayed onto the rotary brush to clean the vehicle and simultaneously wash the rotary brush for a predetermined period of time. It is characterized by cleaning with detergent, and then returning to clean water cleaning by spraying only clean water through the rotating brush.

Further, the rail vehicle cleaning device of the present invention can be used for cleaning a vehicle 1.
The front rotary bushing 1 is provided in front of the rotating bushing 6 in the direction of movement.

A washing tank 10 in which detergent is stored, and a washing tank 10 provided between the front pump and the washing tank, and when the opening operation is performed, the detergent from the detergent storage tank 10 is mixed with the clean water and flows out, and when the closing action is closed, only the clean water is flowed out. a switching means 14; and a timer 13 for detecting that the pre-rotating brush has been used a predetermined number of times or for a predetermined period of time.
a, and a control unit 13 for controlling the switching means to be open for a predetermined period of time based on detection by the timer, and for spraying clean water mixed with detergent to the first rotating brush. It is a feature.

[Effect] When the vehicle 16 is continuously washed with fresh water,
The front rotary brushes 1 and 2 at the front in the direction of travel of the vehicle become contaminated.

When the degree of contamination of the front rotary brushes 1 and 2 is detected and a signal to this effect is manually or automatically input to the control section 13, the control section 13 is activated and the switching means 14 is switched on for a predetermined period of time. Open. Pump 9 is activated in conjunction with the approach of the vehicle.
is activated, the detergent in the detergent storage tank 10 is
From the brush self-cleaning spray pipe 5 to the front rotary brush 1,
It is injected towards 2. Front rotating brush 1, 2
washes the vehicle 16 and washes the front rotary brushes 1 and 2 themselves, and then cleans the control unit 1.
3, since the switching means 14 is opened, only fresh water is sprayed from the brush self-cleaning spray pipe 5 to the front rotary brushes 1 and 2.

Therefore, each time it is detected that the front rotating brushes 1 and 2 are contaminated, the front rotating brushes 1 and 2
are cleaned regularly to ensure optimal vehicle cleaning performance at all times.

[Example] Next, an example of the method and apparatus for cleaning a rail vehicle of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a partially schematic top view showing the same device.

This device is roughly divided into two components: a front stage and a rear stage. The vehicle and the front rotary brushes 1 and 2 are cleaned by switching the The latter part B always washes the vehicle with only fresh water.

To explain the front stage component A, there are parts on both sides of the vehicle 16 (one not shown) that are housed in the frame 17 when not in operation, and which are attached to the vehicle 1 during the cleaning operation.
Pre-stage rotating brushes 1 and 2, each consisting of a pair of front and rear rotating brushes that rotate in the direction of 0 and each rotate in the direction of the arrow (outside symmetry), are upright.

A pre-wash spray pipe 6 for spraying washing water (clean water or detergent) onto the vehicle 16 is installed at the frontmost side in the direction of travel of the vehicle, and at the rear of the front rotary brushes 1 and 2, the outer periphery of the front rotary brushes 1 and 2 is installed. A brush self-cleaning spray pipe 5 is provided to spray cleaning water (clean water or detergent) toward the brush.

10 is a detergent storage tank in which detergent is stored, and when detergent is put into this detergent storage tank 10,
The agitator 1 is activated by manual operation of the controller section 13.
1 to make the detergent concentration uniform. Further, the liquid level of the detergent is detected by the liquid level switch 12,
It is input to the controller section 13.

This detergent can then be supplied to the pre-stage pump 9 via the switching means 14, for example, an electric valve 14 that is opened and closed by a motor 14a, and a liquid volume adjustment valve 15 that adjusts the flow rate.

The pre-stage pump 9 has a negative pressure on its suction side, that is, the suction side of fresh water. When the pre-stage pump 9 is driven, when the electric valve 14 is in the closed state, only fresh water is drawn.
When the electric valve 14 is open, diluted detergent water (detergent water) containing fresh water and detergent is supplied to the brush self-washing spray pipe 5 and the pre-washing spray pipe 6.

Further, the control section 13 controls the agitator 11.
, the input of the liquid level switch 12, and the motor 14a that opens and closes the electric valve 14.If the amount of detergent in the detergent storage tank 10 is below a certain level based on the detection signal of the liquid level switch 12, the electric valve 14 is opened. Control is performed to prevent air from flowing into the pump 9. Furthermore, it has timers 13a and 13b, and the timer 13a has a function of monitoring (timekeeping) a predetermined period for issuing a brush self-cleaning instruction, which will be described later. Further, the timer 13b has a function of monitoring (timekeeping) the brush self-cleaning operation time, which will be described later, and controls the opening and closing of the electric valve 14 for a specified time. A predetermined value for time monitoring can be input to each of the timers 13a and 13b.

On the other hand, to explain the rear stage component B, it operates in the same way as the front rotary brushes 1 and 2 of the front stage component A, and has rear rotary brushes 3 and 4 that can move forward and backward on the side of the vehicle 16. Fresh water spray pipes 7 for spraying fresh water in the direction of the vehicle 16 are provided between the rear rotary brush 3 and the two rear rotary brushes 3 and 4, and at the farthest end in the vehicle traveling direction.

Further, 8 is a rear stage pump, and this rear stage pump 8 sucks up fresh water and supplies it to each fresh water spray pipe 7.

Next, the operation of the above configuration will be explained.

When washing the vehicle 16, the front and rear rotary brushes 1, 2, 3, and 4 are swung by the action of a proximity switch (not shown) that detects the entry of a vehicle, project to a position where they are pressed against the vehicle outer plate, and rotate. Next, the front and rear pumps 8 and 9 are driven to suck up fresh water, and the fresh water is sprayed toward the vehicle 16 from the brush self-cleaning spray pipe 5, the pre-washing spray pipe 6, and the fresh water spray pipe 7. As the vehicle 16 moves forward, it is cleaned by the front and rear rotary brushes 1, 2, 3, and 4 and the spray of fresh water from these brushes.

Next, the brush self-cleaning operation, that is, the front stage component A
The following describes the operation when each vehicle is washed with clean water for a certain period of time or a certain number of times in succession.

When cleaning with fresh water is performed continuously, dirt substances from the vehicle cleaning are transferred to the front side in the direction of travel of the vehicle 16, that is, the front rotary brushes 1 and 2 of the front component A, but the brush self-cleaning spray pipe A sufficient cleaning effect cannot be obtained by cleaning the brushes using only fresh water sprayed from the rotary brushes 5, and as this fresh water cleaning continues, contamination is accumulated on the front rotary brushes 1 and 2 one after another.

The degree of contamination of the front rotary brushes 1 and 2 varies depending on the degree of contamination of the vehicle, but it can be determined that the brushes become contaminated by the number of times the vehicle is washed or by a certain period of time for each vehicle area where the vehicle is located.

Therefore, when the vehicle is washed with fresh water for a certain period of time (for example, several days or weeks), a brush self-cleaning instruction is issued by the method described below. For example, there is a method in which the control section 13 automatically determines whether the closing time of the electric valve 14 matches the value of the certain time set in the timer 13a, or a method in which the control section 13 automatically determines whether the number of times the vehicle is washed and this limit number of times is determined. The control unit 13 determines whether or not the front rotating brushes 1 and 2 are the same by manually inputting an operation signal to the control unit 13 using a switch (not shown) when the front rotating brushes 1 and 2 become contaminated due to manual management. is determined to be the limit of contamination, and when washing the vehicle after this brush self-cleaning instruction is issued, the electric valve 14 is automatically opened for a predetermined time set in the timer 13b of the control unit 13, and the detergent in the detergent storage tank 10 is The liquid is mixed with clean water, and this detergent water is sprayed from the brush self-cleaning spray pipe 5 and the pre-washing spray pipe 6, and the front rotary brushes 1 and 2 are scrubbed on the side of the vehicle while washing the vehicle, and are subjected to the brush self-cleaning action to remove contamination. The substance is washed away. Further, the rear component B cleans the vehicle with fresh water using rotating brushes 3, 4 and a fresh water spray pipe 7.

Then, when the time set by the timer 13b has elapsed, this brush self-cleaning operation ends, and the control unit 1
3, the electric valve 14 is changed from the open state to the closed state to clean the front component A with fresh water.

In the above-described embodiment, the switching means (electric valve) 14 is configured to control only the outflow of detergent from the detergent storage tank 10, and when the electric valve 14 is opened, the detergent and fresh water are mixed by the operation of the front and rear pumps 9. When the electric valve 14 is closed, only clean water is sprayed from the brush self-cleaning spray pipe 5 to the front and rear rotating brushes 1 and 2. In order to switch between water or fresh water, it can be provided at these joints.

Furthermore, since a neutral detergent is used as the detergent in the above-described embodiment, there is no need to perform any particular neutralization treatment on the washing wastewater.

[Effects of the Invention] Since the present invention is configured as described above, the front rotating brush itself is cleaned by adding detergent to clean water for the front rotating brush provided on the front side in the vehicle traveling direction. can be done. Further, detergent can be easily added by simply opening and closing the switching means.

Further, as a cleaning method for a rotating brush for vehicle cleaning, when the rotating brush is continuously washed with fresh water, the rotating brush is periodically washed with a detergent, so that the rotating brush can always be kept clean.

Therefore, in a cleaning method and apparatus that mainly use fresh water for cleaning, it is possible to always obtain an optimal cleaning effect for a vehicle.
