DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulator-cleaning vehicle for cleaning a supporting insulator for supporting a third rail for power supply of a train when the supporting insulator is soiled.

[0002]

2. Description of the Related Art Heretofore, a power supply type traveling line in which a third rail is provided beside a traveling rail is known on a track such as a subway. The third rails are supported by supporting insulators arranged in a row at a predetermined interval, are provided on the side in parallel with the traveling rails, and the train is powered by the third rails and travels.

[0003]

For this reason, if the surface of the supporting insulator is contaminated, the leakage current increases, so that energization becomes impossible, or the withstand voltage decreases, causing a flashover. Power supply may be hindered. Especially in the open orbit, the degree of pollution is more severe than in the subway,
It is necessary to periodically clean the support insulator. For this reason, there has been a demand for the development of a support insulator cleaning device for efficiently cleaning the support insulator. Accordingly, an object of the present invention is to provide a washing vehicle for a third rail support insulator that can easily wash the support insulator.

[0004]

Therefore, according to the present invention, there is provided a vehicle body traveling on a traveling rail, and a moving body provided on the vehicle body at the same speed as the traveling speed so as to be movable in a direction opposite to the traveling direction. And a cleaning unit for cleaning the support insulator is provided on the moving body.

[0005]

The vehicle body runs at a constant speed on the running rail. In this vehicle body, the moving body moves in the opposite direction at the same speed as its running speed. That is, the cleaning attachment moving in the opposite direction at the same speed as the traveling vehicle body remains in one place, and the cleaning part attached to the moving body is cleaned at a fixed position with respect to the support insulator fixed to the ground or the like. Do the work.

[0006]

According to the third aspect of the present invention, there is provided an insulator cleaning vehicle for a third rail supporting insulator, wherein a vehicle main body traveling on a traveling rail and the vehicle main body are movably mounted on the opposite side of the traveling direction at the same speed as the traveling speed. Since the moving body and the cleaning section for cleaning the supporting insulator are provided on the moving body, an effect is obtained that the supporting insulator can be sequentially and efficiently cleaned while the vehicle body is running.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the support insulator W is erected on the ground at predetermined intervals on its side in parallel with the traveling rail 1, and a third rail S is erected on this top. The insulator cleaning vehicle 3 of this embodiment for cleaning the support insulator W provided in this manner is connected to a third rail inspection vehicle 2 provided with a drive mechanism that runs on the traveling rail 1 by itself. The rolling stock is formed by connecting the water tanker 4 to the insulator washing car 3 so that not only the third rail S can be washed but also the third rail can be inspected simultaneously for irregularity, bulging and corrosion / damage of each part.

[0008] The insulator-cleaning vehicle 3 having this vehicle configuration is approximately 2
The vehicle body 10 has a vehicle length of 5 m.
A moving body 11 having a length of about 13 m, which is movable by a moving mechanism (not shown) over substantially the entire length of the side of the moving body 11, is provided. The moving body 11 can be moved back and forth with respect to the vehicle body 10, and can advance and retreat in a lateral direction from the side of the vehicle body 10. The moving mechanism is movable in synchronism with the driving mechanism, and is movable in the backward direction opposite to the traveling direction of the vehicle body 10 at the same speed as the traveling speed.

A washing unit 12 is attached to the moving body 11. In this embodiment, a rod-shaped cleaning brush 12 is employed as a cleaning unit, and a plurality of sets (five sets in this embodiment) of a pair of two at a predetermined interval are rotatably mounted on the moving body 11. The number of the cleaning brushes is determined in accordance with the installation interval of the support insulator W. The set of cleaning brushes 12 can be arranged with one support insulator W interposed therebetween. Brush body 1 planted in
The cleaning can be performed by contacting the shaft 3 while rotating. The cleaning brush 12 protruding from the moving body 11
Are arranged at a height in contact with the side surface of the support insulator W below the erected third rail S. In addition, brush body 1
Although not shown, a supply pipe is extended from the water tanker 4 to the brush body 13 so as to supply cleaning water to the brush body 13.

Next, a description will be given of the washing operation of this embodiment having such a configuration. The washing operation is performed at night after the last train running and before the running of the power generator. First, power supply to the third rail S of the main line is stopped. Then, the insulator cleaning car 3 evacuated to the maintenance base is made to enter the main line and travels to the area to be cleaned. When reaching the area to be cleaned, the cleaning operation of the support insulator W is started. As shown in FIG. 2, the moving body 11 is arranged at the foremost part of the insulator cleaning vehicle 3, the cleaning brush 12 is driven to rotate, and the supply of the cleaning water from the water tank vehicle 4 is started. Then, a pair of brush bodies 13 are respectively axially rotated in the front-rear direction of the support insulator W to simultaneously clean the five support insulators W. At this time, the insulator cleaning car 3 is moved, for example, at a speed of 0.
The vehicle is driven at a constant speed of 36 m, and at the same time, the moving body 11 is moved in the opposite direction at the same speed of 0.36 m / sec. This allows
The moving body 11 keeps the same position with respect to the support insulator W. Then, after 20 seconds, the insulator cleaning car 3 moves forward by 7.2 m, and the moving body 11 moves to the rear of the insulator cleaning car 3 by 7.2 m. During this 20 seconds, the cleaning brush 12
Cleans the support insulator W and ends the cleaning. When the moving body 11 reaches the rear position and finishes cleaning, the moving body 11 retreats into the flank of the vehicle body 10 while maintaining the moving speed, and the cleaning brush 12 does not come into contact with the support insulator W after 5 seconds. Stored in the location (FIG. 4).

Then, the moving body 11 moves forward rapidly and moves to the front end of the insulator cleaning car 3 (FIG. 5), and 14 seconds after the storing of the cleaning brush 12 enters the next step of cleaning the support insulator W. In the next cleaning step, the moving body 11 moves rearward, and the moving body 11 advances from the flank for 5 seconds from the vehicle body 10 to clean the next support insulator W (FIG. 6). . Therefore, the cleaning brush 12 attached to the rearmost part of the moving body 11 cleans the support insulator W immediately before the foremost support insulator W cleaned in the previous step. During this time, the insulator cleaning car 3 is driven at a speed of 0.1 V / sec.
Continue running at a constant speed of 36 m.

When the above steps are repeated and the cleaning of the section to be cleaned is completed, the section is returned to the maintenance base at a high speed, the third rail is again supplied with power, and a series of support insulator cleaning operations is completed.

In this embodiment, not only the cleaning of the third rail S but also the inspection and inspection of the third rail S can be performed by the third rail inspection vehicle 2 at the same time.

In this embodiment, an example in which a traveling drive mechanism is provided in the third rail inspection vehicle 2 is shown. However, the third rail inspection vehicle is not necessarily required. Can be provided. Further, in this embodiment, the moving body 11 can be moved in and out of the vehicle. However, the cleaning brush 12 may be moved in and out of the moving body 11, and in this case, the moving body 11 can be moved in the front-rear direction. It is good. Further, in this embodiment, an example is shown in which the cleaning brush 12 is used as the cleaning unit, but the present invention is not limited to this, and another cleaning type such as a jet water flow may be used.
