【0001】
【発明の属する技術分野】
本発明は、鉄道車両の床下の機器類に付着した塵埃を気吹いて落とす気吹き清掃作業時に使用する気吹き清掃集塵システム及び気吹き清掃方法に関する。
【0002】
【従来の技術】
従来、鉄道車両の点検及び修理などを行う整備場において、鉄道車両の床下のモータ、ジェネレータ、抵抗器、制御機器などの機器類に付着した塵埃をエアガンを用いて圧縮空気で気吹いて落とす気吹き清掃作業が行われている。この気吹き清掃作業では、通常、発生した塵埃を集塵するために、気吹き清掃集塵システムが利用される。
【0003】
このような気吹き清掃集塵システムとしては、例えば図7及び図8に示すものが知られている。この集塵システムは、鉄道車両の左右両側に対峙して配置された一対の集塵装置100、100から構成されている。各集塵装置100は、鉄道車両Tの床下に面して複数の吸込口101を備えており、吸込口101から空気を吸い込み、その吸い込んだ空気を浄化して外部へ排出するものである。
【0004】
【発明が解決しようとする課題】
しかしながら、上記集塵装置100にあっては、気吹き清掃作業で圧縮空気の吐出気流の強さによって跳ね返っていくる塵埃を制御できず、一対の集塵装置100、100によって挟まれた清掃作業域CAから外に塵埃が飛散するのを十分防止できなかった。
【0005】
また、上記集塵装置100では鉄道車両Tの側面下方に面する位置にのみ吸込口101を有しているため、鉄道車両Tの床下中央部から吸込口101までの距離が遠く、この床下中央部付近で発生した塵埃を効率よく吸い込むのは困難であった。
【0006】
更に、上記集塵装置100は、整備場が平面に形成されたピット型のものには対処できるものの、鉄道車両Tの走行面に対して集塵装置100の設置面が一段上がっているホーム型のものには対処できなかった。
本発明は上記課題に鑑みなされたものであり、気吹き清掃作業において、鉄道車両の整備場に塵埃が飛散するのを有効に防止することを第1の目的とし、塵埃を効率よく排除することを第2の目的とし、種々の形状の整備場に順応できることを第3の目的とする。
【0007】
【課題を解決するための手段及び発明の効果】
上記課題を解決するため、請求項1記載の発明は、鉄道車両の床下の機器類に付着した塵埃を気吹いて落とす気吹き清掃作業時に使用する気吹き清掃集塵システムにおいて、前記鉄道車両の左右両側に配置され、前記鉄道車両の床下に面するように設けられた吸込口から空気を吸い込み、該吸い込んだ空気を浄化する集塵装置と、前記集塵装置に挟まれた清掃作業域から外に塵埃が出ないように空気を供給する給気装置とを備え、前記集塵装置は、前記鉄道車両の長手方向に沿って移動可能なように設けられ、前記給気装置を装備しており、前記給気装置は、前記鉄道車両の左右両側から、前記清掃作業域の内側、かつ、前記清掃作業域の中心へ向かって給気することを特徴とする。
【0008】
かかる気吹き清掃集塵システムは、鉄道車両の床下の機器類に付着した塵埃を例えばエアガンにより圧縮空気を用いて塵埃を気吹いて落とす気吹き清掃作業を行う場合に用いられるものである。鉄道車両の床下で発生した塵埃は、集塵装置によって、鉄道車両の床下に面するように設けられた吸込口から空気と共に吸い込まれ浄化される。このとき、給気装置は、集塵装置によって挟まれた清掃作業域から外に塵埃が出ないように空気を供給する。この気吹き清掃集塵システムによれば、給気装置を設けたため、塵埃が清掃作業域から外側に飛散するおそれがなく、鉄道車両の整備場に塵埃が飛散するのを有効に防止できるという効果が得られる。
【0009】
本発明の気吹き清掃集塵システムにおいては、前記給気装置は、前記清掃作業域の内側へ向かって給気する。給気方向は例えばエアカーテンのように清掃作業域の境界に沿う方向とするよりも、清掃作業域の内側へ向かって給気する方がより確実に清掃作業域から外側に塵埃が出ないため好ましいのである。特に、前記給気装置は、作業者が気吹き作業を行うための作業位置の後方から前記清掃作業域の内側に向かって給気するのが好ましい。この場合、気吹き作業を行う作業者が塵埃にまみれるおそれがないため、より好ましいのである。この給気装置の給気風量は、吸込口の吸込風量(排気風量)の5〜30%であることが好ましく、10〜25%であることが特に好ましい。5%未満では清掃作業域からの塵埃の飛散防止効果が弱くなる傾向にあり、30%を越えると空気の吸い込みに影響を及ぼすおそれがあるからである。
【0010】
また、本発明の気吹き清掃集塵システムにおいては、前記吸込口は、前記鉄道車両の側面から前記鉄道車両の床下に潜り込んだ位置に設けるのが好ましい。この場合、吸込口は塵埃発生源に近づくのでより確実に塵埃を含んだ空気を吸い込むことができ、効率よく塵埃を排除できるので好ましいのである。また、前記吸込口は、前記鉄道車両の走行面と前記集合装置の設置面との段差に応じて形成された連結部を介して前記集塵装置に一体化されていてもよく、この場合、ホーム型の整備場(駅のホームのように段差が形成されている整備場)であっても対処できる。
【0011】
更に、本発明の気吹き清掃集塵システムにおいては、前記集塵装置は、前記鉄道車両の長手方向に沿って移動可能なように設けられ、前記給気装置を装備している。この場合、給気装置を装備した集塵装置は鉄道車両の長手方向に沿って移動可能であるため、長い鉄道車両の床下のある機器類につき気吹き清掃を行ったあと、集塵装置を移動させて次の機器類の気吹き清掃を行うことができ、清掃作業の効率が向上する。
【0012】
この移動可能な集塵装置は、塵埃を気吹くために用いる圧縮空気を供給するエアコンプレッサを搭載していてもよい。この場合、気吹き清掃に必要な圧縮空気は集塵装置から供給されるため、鉄道車両の気吹き清掃を連続的に行うことができる。これに対して、例えば鉄道車両に沿って圧縮空気を供給するためのラインが設けられ、このラインに複数箇所に取り出し口が設けられ、この取り出し口から圧縮空気の供給を受ける場合には、集塵装置が所定距離移動するごとに取り出し口を替える作業が必要となる。このため、集塵装置にエアコンプレッサを搭載した方が作業性が向上する。
【0013】
【発明の実施の形態】
以下に、本発明の好適な実施形態を図面に基づいて説明する。
[第1実施形態]
図1は第1実施形態の気吹き清掃集塵システムの正面図、図2は同じく平面図、図3は平地走行用の集塵装置を内側からみたときの説明図である。
【0014】
図1に示すように、本実施形態における鉄道車両の整備場50は、平面状のピット型に形成されている。この整備場50には、一対の鉄道車両用レール53、53が台座54、54上に設けられている。また、鉄道車両用レール53、53の左右両側には、それぞれ、平地走行用の集塵装置10が移動するための一対のレール55、55が溝内に設けられている。
【0015】
本実施形態の気吹き清掃集塵システムは、鉄道車両用レール53、53の左右両側に移動可能に配置された集塵装置10、10によって構成され、鉄道車両Tの床下に配置された機器類に付着した塵埃を気吹いて落とす気吹き清掃作業に使用するものである。
【0016】
集塵装置10は、レール55、55に沿って走行可能なように複数の車輪11が設けられている。この集塵装置10は、装置本体12と、この装置本体12の内側に連結されると共に鉄道車両Tの側面からその床下に潜り込むように設けられた吸込口構成体13と、装置本体12の前後に設けられた袖カバー構成体14、14とから構成されている。
【0017】
装置本体12は、その内部中段付近にフィルタ15が設けられ、このフィルタ15の上方に排気ファン16が設けられ、天井面には排気口18が設けられている。また、装置本体12の内部には、図2に示すように、この集塵装置10の各電気機器類を制御する制御盤19が配設され、この制御盤19は外部から操作可能なリモコン20に接続されている。このリモコン20を操作することにより、集塵装置10の走行駆動の制御つまり運転及びその停止などを指示できる。なお、集塵装置10の電力は、集塵装置10の上方に架設されたトロリーダクト21(図1参照)を介して供給される。
【0018】
吸込口構成体13は、鉄道車両Tの床下空間に面する位置に吸込口22a〜22eを有している。即ち、吸込口22aは吸込口構成体13の内側面に、吸込口22bは前面に、吸込口22cは後面に、吸込口22dは上面に、吸込口22eは斜め上面に設けられている。また、吸込口構成体13の前後には、障害物を機械的に検知するフレーム形状の衝突防止用スクレーパ23、及び、集塵装置10が通電時に点灯するパトライト24が設けられている。更に、吸込口構成体13の内側面には、作業時の照度を確保するための照明器具25が取り付けられている。なお、気吹き作業を行う清掃作業域CAは、一対の集塵装置10、10によって挟まれた領域である。
【0019】
袖カバー構成体14は、装置本体12の前後に取り付けられている。この袖カバー構成体14の鉄道車両Tに面する側は開口している。この袖カバー構成体14の端面の内側には、給気装置としての給気ファン26が設けられている。この給気ファン26は、清掃作業域CAの四隅に設置され、それぞれ清掃作業域CAの内側に向けて空気を供給する。この給気ファン26の吹出口26aは、図3に示すように、上下方向に長く延びている。また、本実施形態では、作業位置(作業者Wが気吹き作業を行うときのポジション)の後方から清掃作業域CAの内側に向かって給気するように設計されている。また、袖カバー構成体14の内部上面には、作業時の照度を確保するための照明器具27が設けられている。また、袖カバー構成体14の内部のうち装置本体12との境界付近には、冬期作業者を暖めるための赤外線ヒータ28が取り付けられている。更に、袖カバー構成体14の端面外側には、障害物を電気的に検知する衝突防止用センサ29が取り付けられている。
【0020】
次に、鉄道車両Tの床下の機器類に付着した塵埃を気吹いて落とす気吹き清掃作業について説明する。まず、リモコン20を操作して集塵装置10をレール55、55に沿って移動させ、鉄道車両Tの床下の塵埃が付着した機器類(以下、発生源Pという、図1参照)を、両集塵装置10、10で挟み込む。
【0021】
そして、この状態でリモコン20を操作して、排気ファン16及び給気ファン26を運転操作して稼働する。すると、集塵装置10、10で囲まれた清掃作業域CA内は、図2の白抜き点線矢印および黒塗り矢印が示す通りの気流が発生する。即ち、新鮮な空気が給気ファン26から清掃作業域CAの内側に向かって供給されると共に、清掃作業域CA内の空気が吸込口22a〜eから吸い込まれ、フィルタ15を下から上へと通過することにより浄化され、その後排気口18から外部へ排出される。
【0022】
このとき排気ファン16と給気ファン26の風量バランスを調整しておくことが好ましい。排気風量が大きいほど集塵効果は高くなるが、風量の増加に伴い集塵装置10の形状は大きくなり、コストが増大するので、必要な風量を見極めることが大切である。また、給気風量は排気風量の5〜30%であることが好ましく、特に10〜25%であることが好ましい。本実施形態においては、排気風量を400m3/min、給気風量を96m3/minと設定した。
【0023】
気吹き清掃作業において、作業者Wは、白抜き実線矢印で示すように、図示しない圧縮エア供給ライン(通常、レール53に沿って配管されている)のエア取り出し口にエアガンのホースを差し込み、このエアガンから圧縮空気を塵埃の発生源Pに噴射する。圧縮空気が噴射されると、塵埃は分散し作業者Wに跳ね返ろうとする。しかし、作業者Wの背面からの給気の気流によりその跳ね返りは抑え込まれ、黒塗り矢印方向に流れて、吸込口22a〜eに吸い込まれる。上記の気流の構成において、整備場内を通過する気流が、清掃作業域CAの気流バランスに影響を及ぼさないように整備場内の気流を2m/s以下の風速にしておくのが好ましい。また、この集塵装置10は走行機能を有しており、走行制御はリモコン20を介して制御盤19にて運転及び停止操作を行う。更に、衝突防止センサ29及び衝突防止用スクレーパ23にて障害物を検知することで、走行における安全性を高めている。なお、集塵装置10を移動させる際には、作業者Wは清掃作業域CAから出て安全な位置で走行制御操作を行う。
【0024】
以上詳述した本実施形態の気吹き清掃集塵システムによれば、以下の効果が得られる。
▲1▼給気ファン26を設けたため、塵埃が清掃作業域CAから外側に飛び出して、整備場に塵埃が飛散するおそれがないという効果が得られる。特に、清掃作業域CAの内側へ向かって給気しているため、前記効果が確実に得られる。また、作業者Wが気吹き作業を行うための作業位置の後方から清掃作業域CA内に向かって給気しているため、作業者Wが塵埃にまみれるおそれがない。
【0025】
▲2▼吸込口22a〜eは、鉄道車両Tの側面から床下に潜り込んだ位置に設けてあるため、吸込口22a〜eは塵埃の発生源Pに近づくのでより確実に塵埃を含んだ空気を吸い込むことができ、塵埃を効率よく排除できる。
▲3▼集塵装置10は、レール55、55に沿って(すなわち鉄道車両Tの長手方向に沿って)移動可能であるため、長い鉄道車両Tの床下のある機器類につき気吹き清掃を行ったあと、集塵装置10を移動させて次の機器類の気吹き清掃を行うことができ、清掃作業の効率が向上する。
【0026】
[第2実施形態]
図4は第2実施形態の気吹き清掃集塵システムの正面図、図5は同じく平面図、図6は段差走行用の集塵装置を内側からみたときの説明図である。
本実施形態における鉄道車両の整備場は、平面部51と段差部52とを備えており、駅のホーム型に形成されている。平面部51には、第1実施形態と同様、一対の鉄道車両用レール53、53が台座54、54上に設けられている。鉄道車両用レール53、53の一方の側(図4にて左側)には、第1実施形態と同様の集塵装置10がレール55、55を移動可能に設けられている。一方、鉄道車両用レール53、53の他方の側(図4にて右側)つまり段差部52側には、段差用の集塵装置40が一対のレール56、56上を移動可能なように設けられている。
【0027】
本実施形態の気吹き清掃集塵システムは、鉄道車両用レール53、53の左右両側に移動可能に配置された集塵装置10、40によって構成され、鉄道車両の床下の機器類に付着した塵埃を気吹いて落とす気吹き清掃作業時に使用するものである。集塵装置10については第1実施形態で既述したとおりであるので、ここでは集塵装置40について説明する。
【0028】
集塵装置40は、概ね集塵装置10と同様の構成であるが、段差部52上に装置本体12及び袖カバー構成体14、14が配置され、平面部51に吸込口構成体13が配置される。このため、吸込口構成体13は、鉄道車両Tの走行面である平面部51と集塵装置40の走行面である段差部52との段差に応じて形成された連結部41を介して、集塵装置40に一体化されている。また、吸込口構成体13のうち上面には吸込口が設けられていない。その他の構成については集塵装置10と同様であるため、同じ構成要素には同じ符号を付し、その説明を省略する。
【0029】
本実施形態の気吹き清掃集塵システムは、上記第1実施形態と同様の作用、効果を奏する上、集塵装置40は連結部41を有しているため、平面部51と段差部52とを有するホーム型の整備場であっても対処できるという効果を奏する。
尚、本発明の実施の形態は、上記実施形態に何ら限定されるものではなく、本発明の技術的範囲に属する限り種々の形態を採り得ることはいうまでもない。
【0030】
例えば、上記各実施形態では、圧縮エア供給ラインのエア取り出し口にエアガンのホースを繋いで圧縮空気を噴射したが、塵埃を気吹くために用いる圧縮空気を供給するエアコンプレッサを集塵装置10(又は集塵装置40)に搭載していてもよい。圧縮エア供給ラインから圧縮エアの供給を受ける場合は、複数箇所にエア取り出し口が設けられ、所定距離移動するごとにエア取り出し口を替える必要があるが、このように集塵装置10(又は集塵装置40)にエアコンプレッサを搭載した場合にはエア取り出し口を替える作業が不要となり、その分作業性が向上する。

BACKGROUND OF THE INVENTION
The present invention relates to an air-blowing cleaning dust collection system and an air-blowing cleaning method used during air-blowing cleaning work that blows off dust attached to equipment under the floor of a railway vehicle.
[0002]
[Prior art]
Conventionally, in maintenance shops that perform inspections and repairs of railway vehicles, dust that adheres to equipment such as motors, generators, resistors, and control equipment under the railway floor is blown off with compressed air using an air gun. Blow cleaning work is performed. In this air blowing cleaning operation, an air blowing cleaning dust collection system is usually used to collect the generated dust.
[0003]
As such an air blowing cleaning dust collection system, what is shown, for example in FIG.7 and FIG.8 is known. This dust collection system is composed of a pair of dust collectors 100, 100 disposed opposite to the left and right sides of a railway vehicle. Each dust collector 100 is provided with a plurality of suction ports 101 facing under the floor of the railway vehicle T, sucks air from the suction ports 101, purifies the sucked air, and discharges it to the outside.
[0004]
[Problems to be solved by the invention]
However, in the dust collector 100, the dust that bounces off due to the strength of the discharge airflow of compressed air in the air blowing cleaning operation cannot be controlled, and the cleaning work area sandwiched between the pair of dust collectors 100, 100 is not possible. It was not possible to sufficiently prevent dust from splashing out of CA.
[0005]
In addition, since the dust collector 100 has the suction port 101 only at the position facing the lower side of the side surface of the railway vehicle T, the distance from the lower floor central portion of the railway vehicle T to the suction port 101 is long. It was difficult to efficiently suck in dust generated near the area.
[0006]
Further, although the dust collector 100 can cope with a pit type in which the maintenance area is formed on a flat surface, the home type in which the installation surface of the dust collector 100 is raised one step higher than the traveling surface of the railway vehicle T. I couldn't deal with it.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a first object is to effectively prevent dust from being scattered in the maintenance area of a railway vehicle in an air blowing cleaning operation, and to efficiently remove dust. The second object is to adapt to maintenance places of various shapes.
[0007]
[Means for Solving the Problems and Effects of the Invention]
In order to solve the above-mentioned problem, an invention according to claim 1 is an air-blow cleaning dust collection system used during an air-blow cleaning operation for blowing and removing dust attached to equipment under the floor of the railway vehicle. From a dust collector that is arranged on both the left and right sides and sucks air from a suction port provided so as to face the floor under the railcar, and purifies the sucked air, and a cleaning work area sandwiched between the dust collectors An air supply device for supplying air so that dust does not come out, and the dust collector is provided so as to be movable along a longitudinal direction of the railway vehicle, and is equipped with the air supply device. The air supply device supplies air from the left and right sides of the railway vehicle toward the inside of the cleaning work area and the center of the cleaning work area .
[0008]
Such an air-blowing cleaning dust collection system is used when performing an air-blowing cleaning operation in which dust attached to equipment under the floor of a railway vehicle is blown off using, for example, compressed air using an air gun. Dust generated under the floor of the railway vehicle is sucked together with air from a suction port provided so as to face the floor of the railway vehicle and purified by a dust collector. At this time, the air supply device supplies air so that dust does not come out from the cleaning work area sandwiched between the dust collectors. According to this air-blowing cleaning dust collection system, since the air supply device is provided, there is no risk of dust scattering outside from the cleaning work area, and it is possible to effectively prevent dust from scattering in the maintenance area of the railway vehicle. Is obtained.
[0009]
In the air blowing cleaning dust collection system of the present invention, the air supply device supplies air toward the inside of the cleaning work area. The air supply direction is more reliable to supply air toward the inside of the cleaning work area than the direction along the boundary of the cleaning work area, such as an air curtain. Is preferred. In particular, the air supply device preferably supplies air toward the inside of the cleaning work area from behind a work position for an operator to perform an air blowing work. In this case, it is more preferable because an operator who performs an air blowing operation is not likely to be covered with dust. The air supply amount of this air supply device is preferably 5 to 30%, and particularly preferably 10 to 25%, of the intake air amount (exhaust air amount) at the intake port. This is because if it is less than 5%, the dust scattering prevention effect from the cleaning work area tends to be weak, and if it exceeds 30%, the air suction may be affected.
[0010]
Moreover, in the air blowing cleaning dust collection system of this invention, it is preferable that the said suction inlet is provided in the position which got under the floor of the said rail vehicle from the side surface of the said rail vehicle. In this case, since the suction port approaches the dust generation source, air containing dust can be sucked more reliably, and dust can be efficiently removed, which is preferable. In addition, the suction port may be integrated with the dust collector through a connecting portion formed according to a step between the traveling surface of the railway vehicle and the installation surface of the collecting device. Even home-type maintenance areas (maintenance areas with steps like the platform of a station) can cope.
[0011]
Further, in the air blow cleaning dust collecting system of the present invention, the dust collecting device is provided so as to be movable along the longitudinal direction of the rail vehicle, that is equipped with the air supply device. In this case, the dust collector equipped with the air supply device can be moved along the longitudinal direction of the railway vehicle. Therefore, after cleaning the equipment under the floor of a long railway vehicle, the dust collector is moved. The air blow cleaning of the next equipment can be performed, and the efficiency of the cleaning work is improved.
[0012]
This movable dust collector may be equipped with an air compressor that supplies compressed air used to blow dust. In this case, since the compressed air required for the air blowing cleaning is supplied from the dust collector, the air blowing cleaning of the railway vehicle can be performed continuously. 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 the line, and when compressed air is supplied from the outlet, Every time the dust device moves a predetermined distance, it is necessary to change the outlet. For this reason, workability is improved when an air compressor is mounted on the dust collector.
[0013]

Next, an air blowing cleaning operation for blowing off dust attached to equipment under the floor of the railway vehicle T will be described. First, the remote controller 20 is operated to move the dust collector 10 along the rails 55, 55, and the devices (hereinafter referred to as the generation source P, see FIG. 1) to which dust under the floor of the railway vehicle T adheres are both The dust collectors 10 and 10 are sandwiched.
[0021]
In this state, the remote controller 20 is operated to operate the exhaust fan 16 and the air supply fan 26 to operate. Then, in the cleaning work area CA surrounded by the dust collectors 10 and 10, an air flow is generated as indicated by the white dotted arrow and the black arrow in FIG. That is, fresh air is supplied from the air supply fan 26 toward the inside of the cleaning work area CA, and the air in the cleaning work area CA is sucked from the suction ports 22a to 22e to move the filter 15 from the bottom to the top. It is purified by passing through and then discharged to the outside through the exhaust port 18.
[0022]
At this time, it is preferable to adjust the air volume balance between the exhaust fan 16 and the air supply fan 26. As the exhaust air volume increases, the dust collection effect increases. However, as the air volume increases, the shape of the dust collector 10 increases and the cost increases, so it is important to determine the required air volume. The supply air volume is preferably 5 to 30% of the exhaust air volume, and more preferably 10 to 25%. In the present embodiment, the exhaust air volume is set to 400 m 3 / min, and the supply air volume is set to 96 m 3 / min.
[0023]
In the air blowing cleaning work, the worker W inserts an air gun hose into an air outlet of a compressed air supply line (usually piped along the rail 53), not shown, as indicated by a white solid arrow, Compressed air is jetted from the air gun to the dust generation source P. When the compressed air is injected, the dust is dispersed and tries to bounce back to the worker W. However, the rebound is suppressed by the air flow from the back of the worker W, flows in the direction of the black arrow, and is sucked into the suction ports 22a to 22e. In the configuration of the airflow described above, it is preferable to keep the airflow in the maintenance area at a wind speed of 2 m / s or less so that the airflow passing through the maintenance area does not affect the airflow balance in the cleaning work area CA. The dust collector 10 has a traveling function, and traveling control is performed by operating and stopping the control panel 19 via the remote controller 20. Furthermore, the safety in driving | running | working is improved by detecting an obstruction in the collision prevention sensor 29 and the scraper 23 for collision prevention. In addition, when moving the dust collector 10, the worker W goes out of the cleaning work area CA and performs a traveling control operation at a safe position.
[0024]
According to the blown cleaning dust collection system of the present embodiment described in detail above, the following effects can be obtained.
{Circle around (1)} Since the air supply fan 26 is provided, there is an effect that the dust does not fly out of the cleaning work area CA and the dust is not scattered on the maintenance area. In particular, since the air is supplied toward the inside of the cleaning work area CA, the above-described effect can be reliably obtained. Further, since the worker W is supplying air into the cleaning work area CA from behind the work position for performing the air blowing work, there is no possibility that the worker W is covered with dust.
[0025]
(2) Since the suction ports 22a to 22e are provided at positions where the railcars T are buried under the floor, the suction ports 22a to 22e approach the dust generation source P, so that air containing dust can be more reliably supplied. It can be sucked in and dust can be efficiently removed.
(3) Since the dust collector 10 is movable along the rails 55 and 55 (that is, along the longitudinal direction of the railway vehicle T), air blow cleaning is performed on equipment under the floor of the long railway vehicle T. After that, the dust collecting apparatus 10 can be moved to perform air blowing cleaning of the next equipment, and the efficiency of the cleaning work is improved.
