ぼすおそれがあるからである。In the air blow cleaning and dust collecting system of the present invention, it is preferable that the air supply device supplies air toward the inside of the cleaning work area. The air supply direction may be a direction along the boundary of the cleaning work area, for example, as an air curtain,
It is preferable to supply air toward the inside of the cleaning work area because dust is not more reliably emitted from the cleaning work area to the outside. In particular, it is preferable that the air supply device supplies air from the rear of the work position where the worker performs the air blowing operation toward the inside of the cleaning work area. In this case, it is more preferable because the worker who performs the air blowing operation is not likely to be covered with dust. The air supply volume of this air supply device is preferably 5 to 30%, more preferably 10 to 25% of the suction air volume (exhaust air volume) of the suction port. If it is less than 5%, the effect of preventing dust from scattering from the cleaning work area tends to be weak, and if it exceeds 30%, there is a possibility that the air suction may be affected.

In this case, the suction port is closer to the dust generation source, so that the air containing the dust can be more reliably sucked, and the dust can be efficiently removed, which is preferable. Further, the suction port may be integrated with the dust collecting device via a connecting portion formed according to a step between the running surface of the railway vehicle and the installation surface of the collecting device, in this case, This can be handled even in a home-type maintenance site (a maintenance site with steps formed like a station platform).

る。Further, in the air blowing / cleaning dust collecting system of the present invention, the dust collecting device is provided so as to be movable in a longitudinal direction of the railway vehicle, and is provided with the air supply device. Is preferred. In this case, since the dust collector equipped with the air supply device can be moved along the longitudinal direction of the railway car, the dust collector is moved after cleaning the equipment under the floor of the long railway car by air blowing. As a result, the next device can be blown and cleaned, and the efficiency of the cleaning operation is improved.

プレッサを搭載した方が作業性が向上する。The movable dust collector may have an air compressor for supplying compressed air used for blowing dust. In this case, since the compressed air required for the air blowing cleaning is supplied from the dust collecting device, the air blowing cleaning of the railway vehicle can be continuously performed. On the other hand, for example, a line for supplying compressed air is provided along a railway vehicle, and a plurality of outlets are provided in this line. It is necessary to change the outlet every time the dust device moves a predetermined distance. Therefore, the workability is improved by mounting the air compressor on the dust collecting device.

位置で走行制御操作を行う。In the air blowing cleaning operation, the worker W puts a hose of an air gun into an air outlet of a compressed air supply line (not shown) (generally piped along the rail 53) as shown by a solid white arrow. The compressed air is injected from the air gun to the dust generation source P. When the compressed air is injected, the dust is dispersed and tends to rebound to the worker W. However, the rebound is suppressed by the air flow of the supply air from the back surface of the worker W, flows in the black arrow direction, and is sucked into the suction ports 22a to 22e. In the above configuration of the airflow, the airflow passing through the maintenance yard is the cleaning work area C.
It is preferable to keep the airflow in the maintenance yard at a wind speed of 2 m / s or less so as not to affect the airflow balance of A. Further, the dust collecting apparatus 10 has a traveling function, and the traveling control is performed by a control panel 19 via a remote controller 20 to operate and stop. Further, by detecting an obstacle with the collision prevention sensor 29 and the collision prevention scraper 23, safety in traveling is enhanced. When the dust collector 10 is moved, the worker W goes out of the cleaning work area CA and performs a traveling control operation at a safe position.

There is no effect that the dust jumps out from the outside and the dust is scattered to the maintenance yard. In particular, since the air is supplied toward the inside of the cleaning work area CA, the above-described effect is reliably obtained. Further, since the worker W supplies air from behind the working position for performing the blowing operation toward the inside of the cleaning work area CA, the worker W is not likely to be covered with dust.
