Description
本発明は、消火用タイヤ及び建設作業場で発生した火災を消火するためのシステムに関する。 The present invention relates to a fire extinguishing tire and a system for extinguishing a fire generated in a construction work place.
例えば、坑道等の建設作業場の狭隘な空間で火災が発生した場合には、坑道内が強制的に通気されていたり、自然通気が生じていることで、火災が広範囲に拡大しやすい。このため、火災の拡大を防止するためにも火災発生後に迅速な消火活動を行うことが重要になる。 For example, when a fire breaks out in a narrow space of a construction work place such as a tunnel, the fire is likely to spread over a wide area because the inside of the tunnel is forcibly ventilated or natural ventilation occurs. Therefore, in order to prevent the spread of the fire, it is important to carry out prompt fire extinguishing activities after the fire breaks out.
これに対し、従来からスプリンクラーなどを設置し、火災を検知するとともに水や粉末消火剤などを放出し、早期に消火を行えるようにする消火システムがあらゆる分野で用いられている（例えば、特許文献１、特許文献２参照）。 On the other hand, conventional fire extinguishing systems that install sprinklers and the like to detect fires and release water and powder fire extinguishing agents so that fires can be extinguished at an early stage have been used in all fields (for example, patent documents). 1. See Patent Document 2).
しかしながら、坑道等を構築する工事現場では最も火災が発生する可能性がある作業を行う場所が先に延びていく等常に変化するため、消火に有効な位置にスプリンクラーなどの消火システムを適用することは難しく、他の迅速な消火活動を可能にする工事現場に適した新たな手法が強く望まれていた。 However, at the construction site where a tunnel is constructed, the place where the work that may cause the most fire is performed is constantly changing, so apply a fire extinguishing system such as a sprinkler to a position that is effective for extinguishing the fire. Is difficult, and a new method suitable for construction sites that enables other rapid fire extinguishing activities has been strongly desired.
本発明は、上記事情に鑑み、坑道等を構築する工事現場で迅速な消火活動を可能にする消火用タイヤ及び建設作業場の消火システムを提供することを目的とする。 In view of the above circumstances, it is an object of the present invention to provide a fire extinguishing tire and a fire extinguishing system for a construction work place, which enable rapid fire extinguishing activities at a construction site where a tunnel or the like is constructed.
上記の目的を達するために、この発明は以下の手段を提供している。 In order to achieve the above object, the present invention provides the following means.
本発明の消火用タイヤは、タイヤ外郭の内部に高圧気体を加圧状態で封入した内側チューブが設けられるとともに、前記内側チューブと前記タイヤ外郭の間の空間に消火剤を封入して構成されており、軸線中心の内側に軸線方向の側面視で同心円状の前記内側チューブが設けられ、前記内側チューブの外側周囲の前記内側チューブと前記タイヤ外郭の間に前記消火剤が封入されていることを特徴とする。 The fire extinguishing tire of the present invention is configured by providing an inner tube in which a high-pressure gas is sealed in a pressurized state inside the tire outer shell and enclosing a fire extinguishing agent in the space between the inner tube and the tire outer shell. The inner tube is provided concentrically in a side view in the axial direction inside the center of the axis, and the fire extinguishing agent is sealed between the inner tube around the outer side of the inner tube and the outer shell of the tire . It is a feature.
さらに、本発明の消火用タイヤは、タイヤ外郭の内部に高圧気体を加圧状態で封入した内側チューブが設けられるとともに、前記内側チューブと前記タイヤ外郭の間の空間に消火剤を封入して構成されており、軸線方向内側に前記内側チューブが設けられ、前記内側チューブの軸線方向外側の前記内側チューブと前記タイヤ外郭の間に前記消火剤が封入されていることを特徴とする。 Further, the fire extinguishing tire of the present invention is provided with an inner tube in which a high-pressure gas is sealed in a pressurized state inside the tire outer shell, and a fire extinguishing agent is sealed in the space between the inner tube and the tire outer shell. The inner tube is provided on the inner side in the axial direction, and the fire extinguishing agent is sealed between the inner tube on the outer side in the axial direction of the inner tube and the outer shell of the tire.
また、本発明の消火用タイヤは、タイヤ外郭の内部に高圧気体を加圧状態で封入した内側チューブが設けられるとともに、前記内側チューブと前記タイヤ外郭の間の空間に消火剤を封入して構成されており、軸線中心の周方向に間隔をあけて複数の内側チューブが設けられ、周方向に隣り合う内側チューブの間に前記消火剤が封入されていることを特徴とする。
Further, the fire extinguishing tire of the present invention is provided with an inner tube in which a high-pressure gas is sealed in a pressurized state inside the tire outer shell, and a fire extinguishing agent is sealed in the space between the inner tube and the tire outer shell. It is characterized in that a plurality of inner tubes are provided at intervals in the circumferential direction of the center of the axis, and the fire extinguishing agent is sealed between the inner tubes adjacent to each other in the circumferential direction.
本発明の建設作業場の消火システムは、建設作業車のタイヤとして上記のいずれかの消火用タイヤが用いられていることを特徴とする。 The fire extinguishing system of the construction work place of the present invention is characterized in that any of the above-mentioned fire extinguishing tires is used as the tire of the construction work vehicle.
本発明の消火用タイヤ及び建設作業場の消火システムにおいては、火災が発生した際にタイヤから消火剤を噴出させることができる。これにより、スプリンクラーなどの消火設備を設けることが困難な坑道等を構築する工事現場においても、迅速な消火活動が可能になる。 In the fire extinguishing tire of the present invention and the fire extinguishing system of a construction work place, a fire extinguishing agent can be ejected from the tire when a fire occurs. This enables quick fire extinguishing activities even at construction sites where it is difficult to install fire extinguishing equipment such as sprinklers.
以下、図１から図３を参照し、本発明の一実施形態に係る消火用タイヤ及び建設作業場の消火システムについて説明する。 Hereinafter, a fire extinguishing tire and a fire extinguishing system in a construction work place according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.
本実施形態の建設作業場の消火システムでは、図１に示すように、ダンプトラック等のタイヤ駆動型の大型重機（建設作業機）のタイヤ１の中に消火用水などの消火剤２を入れておき、通常時はこの状態で重機を稼働させ、火災発生時には、消火剤２をタイヤ１から噴射させるようにして消火活動を行う。
In the fire extinguishing system of the construction work place of the present embodiment, as shown in FIG. 1, a
ここで、工事現場では、重機に起因した事故が考えられ、重機の使用が多い坑道の工事現場では、例えば切羽付近での重機同士の衝突事故が原因となって火災が発生することが考えられる。このようにタイヤ１内に消火剤２を入れた重機自体が事故を起こすなどして火災が発生した場合には、タイヤ１が燃焼し破裂した時点でタイヤ１内の消火剤２が放出されて、消火を担うこともできる。
Here, at the construction site, it is conceivable that an accident caused by heavy machinery may occur, and at the construction site of a tunnel where heavy machinery is frequently used, it is conceivable that a fire may occur due to a collision accident between heavy machinery near the face, for example. .. In the event of a fire caused by a heavy machine containing the
より詳細に、例えば、本実施形態の消火用タイヤ１は、図１に示すように、その内部に高圧気体３を加圧状態で封入した内側チューブ４を、タイヤ外郭（タイヤ１の外郭を形成するタイヤゴム）５の内部に略同心円状に配置し、さらに、内側チューブ４とタイヤ外郭５の間に消火用水などの消火剤２を封入しておく。また、タイヤ外郭５の所定位置に消火剤２の放出ノズルを取り付けておく。
More specifically, for example, in the fire extinguishing tire 1 of the present embodiment, as shown in FIG. 1, an
このように構成した本実施形態の消火用タイヤ１においては、通常時には放出ノズルが閉じて消火剤２、高圧気体３が密閉された状態であるため、タイヤ本来の機能と維持し、これを装着した重機などを通常通りに稼働させることができる。
In the fire extinguishing tire 1 of the present embodiment configured in this way, since the discharge nozzle is normally closed and the
一方、火災が発生した際には、運転者等の操作者が放出ノズルを開く操作を行うなどすると、タイヤ外郭５と内側チューブ４の間に封入された消火剤２が放出ノズルから外側に噴出する。また、このとき、内側チューブ４に高圧気体３が封入されているため、消火剤２が放出ノズルから外側に噴出するとともに内側チューブ４が膨張し、消火剤２を放出ノズルから所望の圧力をもって噴出させることができる。さらに、消火剤２が封入されていた領域が内側チューブ４で満たされるため、消火剤２の噴出中、噴出後もタイヤ１の接地圧を好適に確保でき、走行に支障をきたすことがない。
On the other hand, in the event of a fire, when an operator such as a driver opens the discharge nozzle, the
これにより、火災が発生した際に、タイヤ１から消火剤２を噴出させながら重機等の車両を走行させたり、車両を所望の位置に停止させた段階でタイヤ１から消火剤２を所望の方向に噴出させて、消火活動を行うことが可能になる。
As a result, when a fire breaks out, the
また、この消火用タイヤ１を装着した車両が事故を起こし、消火用タイヤ１が燃焼したり、破損した場合にも、内側チューブ４が膨張しつつ消火剤２がタイヤ１の破損個所から放出される。このため、車両の事故の際の火災の発生、拡大（延焼）を効果的に食い止めることが可能になる。
Further, even if a vehicle equipped with the fire extinguishing tire 1 causes an accident and the fire extinguishing tire 1 burns or is damaged, the
なお、本実施形態の消火用タイヤ１の構成は、必ずしも上記のように限定しなくてもよい。 The configuration of the fire extinguishing tire 1 of the present embodiment is not necessarily limited as described above.
例えば、タイヤ１の内空（タイヤ外郭５内）の車軸側に高圧気体３を封入した内側チューブ４を設け、タイヤ１の内空の内側チューブ４よりも車両外側（タイヤ露出側）に消火剤２を封入しておき、火災発生時に内側チューブ４を車両外側に膨張させつつ、タイヤ１の側面側から車両の側方外側に向けて消火剤２を噴出させるように構成してもよい。
For example, an
さらに、タイヤ外郭５内の軸線中心の周方向に複数の内側チューブ４を間隔をあけて設け、周方向に隣り合う内側チューブ４の間に消火剤２を封入しておき、火災発生時に複数の内側チューブ４を膨張させつつ消火剤２を噴出させるように構成してもよい。
Further, a plurality of
このように構成しても上記の消火用タイヤ１と同様の作用効果を得ることができる。 Even with such a configuration, the same action and effect as the above-mentioned fire extinguishing tire 1 can be obtained.
したがって、本実施形態の消火用タイヤ１及び建設作業場の消火システムによれば、スプリンクラーなどの消火設備を設けることが困難な坑道等を構築する工事現場においても、迅速な消火活動が可能になる。 Therefore, according to the fire extinguishing tire 1 of the present embodiment and the fire extinguishing system of the construction work place, rapid fire extinguishing activities can be performed even at a construction site where it is difficult to install fire extinguishing equipment such as a sprinkler.
以上、本発明に係る消火用タイヤ及び建設作業場の消火システムの一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。 Although one embodiment of the fire extinguishing tire and the fire extinguishing system of the construction work place according to the present invention has been described above, the present invention is not limited to the above one embodiment and can be appropriately changed without departing from the spirit thereof.
