Description

本発明は、大型消防車両に関し、石油コンビナー等で使用する大型消防車両に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large fire-fighting vehicle, and more particularly to a large fire-fighting vehicle used in petroleum complexes and the like.

石油コンビナートや火力発電所等には、高所放水車、大型化学消防車、および泡原液搬送車などの特定の消防車両およびそれらを操作する多数の消防要員を常駐させておく必要がある。このような複数の特定消防車両を配備し常に出動可能にしておくこと、また多数の消防要員を常駐させることには、多大な設備、コストおよび労力を必要とする。 In petroleum complexes, thermal power plants, etc., it is necessary to permanently station specific firefighting vehicles such as high-altitude water cannons, large chemical firefighting vehicles, and foam concentrate transport vehicles, and a large number of firefighting personnel to operate them. Deploying such a plurality of specific fire-fighting vehicles so that they can be dispatched at all times and stationing a large number of fire-fighting personnel require a great deal of equipment, cost and labor.

このため、特定の消防車両の操作の自動化および省力化する方法が提案されている（例えば特許文献１を参照）。しかし、この方法では、消防車両の台数を減らすことはできず、また消防車両同士を接続するのに一定時間を要し、さらに車庫面積を低減したり、消防要員を削減する効果が、十分には得られない。 For this reason, a method of automating the operation of a specific fire engine and saving labor has been proposed (see Patent Document 1, for example). However, this method cannot reduce the number of fire engines, and it takes a certain amount of time to connect the fire engines. is not obtained.

近年、高所放水車および大型化学消防車を一体化し、大型化学高所放水車とすることにより、必要とされる消防車両の台数を減らし、メンテナンスや車庫にかかる設備費や労費を減らすと共に、高所放水車と大型化学消防車との接続操作をなくし、消防要員の人数を少なくすることが試みられ一定の成果が得られている。しかし、石油コンビナートや火力発電所等の大規模化に伴い、消防車両の機能、性能および安全性を維持、向上すると共に、設備費や労費を更に削減することが求められている。 In recent years, by integrating high-altitude water cannon trucks and large chemical fire trucks into a large chemical high-altitude water cannon truck, the number of fire trucks required has been reduced, and equipment and labor costs for maintenance and garages have been reduced. Attempts have been made to reduce the number of firefighting personnel by eliminating the connection operation between the high-altitude water cannon truck and the large chemical fire engine, and certain results have been obtained. However, as petroleum complexes, thermal power plants, etc. become larger in scale, it is required to maintain and improve the function, performance and safety of fire engines and to further reduce facility and labor costs.

特開平１１‐１３７７０９号公報JP-A-11-137709

本発明の目的は、石油コンビナー等で使用する消防車両の機能、性能および安全性を維持、向上すると共に、設備費や労費を更に削減可能にする大型消防車両を提供することにある。 An object of the present invention is to provide a large-sized fire-fighting vehicle that maintains and improves the functions, performance, and safety of fire-fighting vehicles used in petroleum complexes and the like, and that can further reduce equipment and labor costs.

本発明の目的を達成する大型消防車両は、泡消火薬剤タンク、高所泡消火薬剤放射手段および運転室を有する大型消防車両であって、前記泡消火薬剤タンクの容量が５．８ｍ3以上であり、前記高所泡消火薬剤放射手段が、泡消火薬剤を放射する筒先、該筒先を地上から２２ｍ以上の高さに配置する塔または梯子、および放水ポンプを有し、前記運転室内に、前記泡消火薬剤タンクおよび高所泡消火薬剤放射手段を操作する制御手段を有すると共に、操向方向と逆方向に後輪を舵角する後輪操舵手段を有することを特徴とする。 A large fire-fighting vehicle for achieving the object of the present invention is a large-sized fire-fighting vehicle having a foam fire-extinguishing agent tank, high-altitude foam fire-extinguishing agent discharge means and a cab, wherein the capacity of the foam fire-extinguishing agent tank is 5.8 m 3 or more. wherein the high-altitude foam fire-extinguishing agent spraying means has a nozzle for ejecting foam fire-extinguishing agent, a tower or ladder for arranging the nozzle at a height of 22 m or more above the ground, and a water discharge pump; It is characterized by having control means for operating the foam fire extinguishing agent tank and high altitude foam fire extinguishing agent discharge means, and having rear wheel steering means for steering the rear wheels in the direction opposite to the steering direction.

本発明の大型消防車両によれば、高所放水車、大型化学消防車および泡原液搬送車を一体化したので、高所放水車および大型化学消防車の間、大型化学消防車および泡原液搬送車の間を接続する操作を省くことができると共に、泡消火薬剤タンクおよび高所泡消火薬剤放射手段を操作する制御手段を運転室内に配置したので、火災等の現場に到着後、迅速に消火活動等を開始することができる。また、その操作に携わる消防要員の数を少なくすることができる。更に、大型消防車両を格納する車庫の面積を減らし、かつそのメンテナンスに関わる人員も少なくすることができる。従来、高所放水車、大型化学消防車および泡原液搬送車を一体化すると、大型消防車両の全長が長くなり、法令等で定められた石油コンビナートや火力発電所等の工場内の道路を走行するのが困難になると懸念されたが、操向方向と逆方向に後輪を舵角する後輪操舵手段を有することにより、工場内の道路をスムーズに走行することができる。 According to the large-sized fire engine of the present invention, the high-altitude water-cannon vehicle, the large-scale chemical fire-fighting vehicle, and the foam concentrate transport vehicle are integrated. It is possible to omit the operation to connect between cars, and the control means for operating the foam fire extinguishing agent tank and the high altitude foam fire extinguishing agent discharge means are arranged in the driver's cab, so that the fire can be quickly extinguished after arriving at the site of the fire, etc. Activities can be started. Also, the number of firefighting personnel involved in the operation can be reduced. Furthermore, the area of the garage for storing the large fire engine can be reduced, and the number of personnel involved in its maintenance can also be reduced. Conventionally, when a high-altitude water cannon truck, a large chemical fire engine, and a foam concentrate transport vehicle are integrated, the overall length of the large fire truck becomes long, and it runs on roads within factories such as petroleum complexes and thermal power plants as stipulated by laws and regulations. Although it was feared that it would be difficult to steer the vehicle, by having the rear wheel steering means for steering the rear wheels in the direction opposite to the steering direction, it is possible to smoothly run on the roads in the factory.

前記大型消防車両は、更に泡消火薬剤の混合手段を有することにより、給水から放水までのすべてを一台の大型消防車両で行うことができ、大型屋外貯蔵タンク火災等に迅速に対処することができる。 The above-mentioned large fire truck is equipped with foam fire extinguishing agent mixing means, so that a single large fire truck can carry out everything from water supply to water discharge, and it is possible to quickly deal with large outdoor storage tank fires, etc. can.

前記大型消防車両は、回転半径が最小になるように走行するとき、外側前輪が描く円の半径が１１ｍ以下、内側後輪が描く円の半径が７ｍ以下であるとよく、交差する幅員約９ｍの道路を略直角に曲がることができる。 When the large fire truck runs so that the turning radius is minimized, the radius of the circle drawn by the outer front wheels is preferably 11 m or less, the radius of the circle drawn by the inner rear wheels is 7 m or less, and the width of the intersection is about 9 m. The road can be turned at an almost right angle.

前記大型消防車両は、その走行に関係する通信信号、および前記泡消火薬剤タンクおよび高所泡消火薬剤放射手段の制御に関係する通信信号が、ＣＡＮ－ＢＵＳシステムを介して接続されているとよく、大型消防車両に搭載されたあらゆる通信信号を1つのネットワークに統合し、信頼性を向上すると共に、配線ハーネスを軽量化することができる。なお、本明細書において、ＣＡＮ－ＢＵＳシステムとは、ＩＳＯ １１８９８に準拠した通信規格をいう。 Communication signals related to running of the large fire engine and communication signals related to control of the foam tank and high-altitude foam fire extinguishing means are preferably connected via a CAN-BUS system. , All communication signals mounted on large fire trucks can be integrated into one network, improving reliability and reducing the weight of wiring harnesses. In this specification, the CAN-BUS system refers to a communication standard conforming to ISO 11898.

以下、更に詳しく本発明の大型消防車両について、図面を参照して説明する。 Hereinafter, the large fire truck of the present invention will be described in more detail with reference to the drawings.

大型消防車両は、泡消火薬剤タンクおよび高所泡消火薬剤放射手段等の消防装置と、運転室、操舵手段および車両エンジン等の走行装置を有する。消防装置として、泡消火薬剤タンクおよび高所泡消火薬剤放射手段の他に、泡消火薬剤ポンプ、放水ポンプ、給水ポンプ、自動比例泡混合装置、消防ホース、給水手段（吸管、真空ポンプ、ピストンプライミングポンプ）、ハンドノズル（手持放水銃）、ハンドノズル用ホースリール、等を配備することができる。また、走行装置として、運転室、操舵手段および車両エンジンの他に、燃料タンク、冷却システム、各種オイル管理システム、各種通信システム、等を配備することができる。 A large-sized fire fighting vehicle has a fire extinguishing device such as a foam fire extinguishing agent tank and high altitude foam fire extinguishing agent means, and a running device such as a driver's cab, a steering means and a vehicle engine. In addition to foam fire extinguishing agent tanks and high altitude foam fire extinguishing means, fire extinguishing equipment includes foam fire extinguishing agent pumps, water discharge pumps, water supply pumps, automatic proportional foam mixing devices, fire hoses, water supply means (suction pipe, vacuum pump, piston priming) pump), hand nozzle (hand-held water gun), hose reel for hand nozzle, etc. can be deployed. In addition to the driver's cab, the steering means, and the vehicle engine, a fuel tank, cooling system, various oil management systems, various communication systems, and the like can be provided as the traveling device.

図１に示すように、大型消防車両１は、泡消火薬剤タンク６、筒先３および塔４からなる高所泡消火薬剤放射手段２および運転室７を有し、更に放水ポンプ５や泡消火薬剤ポンプ等を収容したポンプ室、各種消防用装備および工具等を格納した資材室１１、等からなる。 As shown in FIG. 1, a large-sized fire engine 1 has a foam fire extinguishing agent tank 6, a high altitude foam fire extinguishing agent discharge means 2 consisting of a nozzle 3 and a tower 4, and a cab 7. It consists of a pump room containing pumps and the like, a material room 11 containing various firefighting equipment and tools, and the like.

大型消防車両１は、図２に示すように、水１５が給水手段により、放水ポンプ５へ送られ、放水ポンプ５により、加圧され混合手段９を通り、高所泡消火薬剤放射手段２の筒先３および／またはハンドノズル１２から放射される。一方、泡消火薬剤タンク６に収容された泡消火薬剤１４は、泡消火薬剤ポンプ１０により、放水圧とほぼ同じ圧力に加圧され、混合手段９により、水と混合する。上記の他、放水操作を安全かつ円滑に行うため、必要な配管、バルブ、各種計器等が備えられている。 In the large fire engine 1, as shown in FIG. Emitted from the tip 3 and/or the hand nozzle 12 . On the other hand, the foam fire-extinguishing agent 14 stored in the foam fire-extinguishing agent tank 6 is pressurized by the foam fire-extinguishing agent pump 10 to approximately the same pressure as the water discharge pressure, and is mixed with water by the mixing means 9 . In addition to the above, necessary piping, valves, various instruments, etc. are provided for safe and smooth water discharge operation.

泡消火薬剤タンク６は、その容量が５．８ｍ3以上であり、好ましくは６ｍ3以上１０ｍ3以下である。泡消火薬剤タンク６の容量を５．８ｍ3以上にすることにより、石油コンビナーや火力発電所等で起きる火災等に適切に対処することができる。泡消火薬剤タンク６は、その大容量を確保するため、略車両幅と同じ大きさのほぼ直方体の樹脂製タンクであるとよい。樹脂としては、繊維強化プラスチック（ＦＲＰ）が好ましく、例えば熱硬化性樹脂を母材とし炭素繊維強化またはガラス繊維強化のＦＲＰが挙げられる。また、大型消防車両は、泡消火薬剤タンク６は、その下流側に、泡消火薬剤ポンプ１０、泡消火薬剤と水との混合手段９、例えば自動比例泡混合装置を有するとよい。泡消火薬剤タンク６から泡消火薬剤ポンプ１０を介し圧送された泡消火薬剤は、自動比例泡混合装置で自動的に一定の比率で水と混合され、筒先３から放射する泡へと調製される。ここで、水は、河川、池、湖、海から給水ポンプで汲み上げた水や、消火栓から供給される水を用いることができる。 The foam fire extinguishing agent tank 6 has a capacity of 5.8 m 3 or more, preferably 6 m 3 or more and 10 m 3 or less. By setting the capacity of the foam fire extinguishing agent tank 6 to 5.8 m 3 or more, it is possible to appropriately deal with fires that occur in petroleum complexes, thermal power plants, and the like. In order to ensure a large capacity, the foam fire extinguishing agent tank 6 is preferably a rectangular parallelepiped resin tank having substantially the same size as the width of the vehicle. As the resin, fiber reinforced plastic (FRP) is preferable, and for example, carbon fiber reinforced or glass fiber reinforced FRP using a thermosetting resin as a base material can be used. In the large fire truck, the foam tank 6 preferably has, downstream thereof, a foam pump 10 and means for mixing foam and water 9, such as an automatic proportional foam mixer. The foam fire extinguishing agent pressure-fed from the foam fire extinguishing agent tank 6 through the foam fire extinguishing agent pump 10 is automatically mixed with water at a constant ratio by the automatic proportional foam mixing device, and prepared into foam emitted from the nozzle 3. . Here, the water can be water pumped from a river, pond, lake, or sea by a water supply pump, or water supplied from a fire hydrant.

大型消防車両は、自動比例泡混合装置で混合した泡を、高所泡消火薬剤放射手段２に送水する。高所泡消火薬剤放射手段２は、混合した泡を放水ポンプ５により加圧した水と共に、１．４ＭＰａの吐出圧力で毎分３．０ｍ3以上、好ましくは毎分３．０ｍ3以上５．０ｍ3以下の放水を可能にする。なお、放水ポンプ５等の消防装置の動力源は、消防装置用エンジンを備えてもよいし、或いは走行用の車両エンジンの出力を共有してもよい。 The large fire truck sends foam mixed by the automatic proportional foam mixer to the high altitude foam fire extinguishing agent spraying means 2 . The high-altitude foam fire extinguishing agent spraying means 2 discharges mixed foam together with water pressurized by a water discharge pump 5 at a discharge pressure of 1.4 MPa at a discharge pressure of 3.0 m 3 or more per minute, preferably 3.0 m 3 or more per minute5. Enables water discharge of 0 m 3 or less. The power source of the fire extinguishing device such as the water discharge pump 5 may be provided with the engine for the fire extinguishing device, or may share the output of the vehicle engine for traveling.

放水ポンプ５から圧送された泡（泡消火薬剤および水を混合した泡）は、高所泡消火薬剤放射手段２に備えられた筒先３から、火元等へ放射される。ここで、筒先３は地上から２２ｍ以上、好ましくは２２ｍ以上３５ｍ以下の高さに配置される。すなわち、筒先３は、塔高２２ｍ以上の塔４または梯子（以下、まとめて「塔」と記載する。）の先に配置することができる。この筒先３は、その方向および角度を遠隔操作できるとよい。 The foam (foam mixed with foam fire extinguishing agent and water) pressure-fed from the water pump 5 is radiated to the origin of the fire or the like from the nozzle 3 provided in the high-altitude foam fire extinguishing agent radiating means 2 . Here, the nozzle tip 3 is arranged at a height of 22 m or more, preferably 22 m or more and 35 m or less from the ground. That is, the tip 3 can be arranged at the tip of a tower 4 having a tower height of 22 m or more or a ladder (hereinafter collectively referred to as "tower"). It is preferable that the direction and angle of the tip 3 can be remotely controlled.

高所泡消火薬剤放射手段２が有する塔４は、塔高２２ｍ以上であれば特に限定されるものではなく、折り畳み、伸縮、旋回、およびこれらの組み合わせのいずれの形態でもよい。図３は、大型消防車両が備える塔４の動作を例示する説明図である。この塔４の基部は、折り畳み式であり、大型消防車両の屋根部に折り畳まれた状態から略垂直に起立させると約８ｍの高さになる。さらに、塔４の前方を延伸させ、上方に起こすことにより、塔高２２ｍ以上の高さを確保することができる。 The tower 4 of the high-altitude foam fire extinguishing means 2 is not particularly limited as long as it has a tower height of 22 m or more, and may be in any form of folding, expansion and contraction, turning, and combinations thereof. FIG. 3 is an explanatory diagram illustrating the operation of the tower 4 provided on the large fire engine. The base of this tower 4 is of a foldable type, and has a height of about 8 m when erected approximately vertically from the folded state on the roof of a large fire truck. Furthermore, by extending the front part of the tower 4 and raising it upward, a tower height of 22 m or more can be secured.

大型消防車両の運転室７内には、泡消火薬剤タンク６および高所泡消火薬剤放射手段２を操作する制御手段を有する。運転室７内に、消防に係るすべての装置および走行に係るすべての装置を操作可能にする制御手段を配置する。これにより、高所放水車、大型化学消防車、および泡原液搬送車のすべての機能を有しながら、それらの操作に必要な消防要員の人数を少なくすることができる。 A control means for operating the foam fire extinguishing agent tank 6 and the high altitude foam fire extinguishing agent discharge means 2 is provided in the driver's cab 7 of the large fire engine. In the driver's cab 7, a control means is arranged to enable operation of all devices related to fire fighting and all devices related to running. As a result, it is possible to reduce the number of firefighting personnel required to operate them while having all the functions of a high-altitude water cannon truck, a large chemical fire truck, and a foam liquid carrier truck.

大型消防車両は、その走行に関係する通信信号、および泡消火薬剤タンク６および高所泡消火薬剤放射手段２等の消防装置の制御に関係する通信信号が、ＣＡＮ－ＢＵＳシステムを介し、1つのネットワークに統合されて、接続されることが好ましい。これにより、大型消防車両を制御するときの信頼性を向上すると共に、配線ハーネス等の通信信号関係の配線量を削減し、軽量化することができる。 Communication signals related to the running of the large fire fighting vehicle and communication signals related to the control of the fire extinguishing equipment such as the foam fire extinguishing agent tank 6 and the high altitude foam extinguishing agent discharge means 2 are transmitted via the CAN-BUS system. It is preferably integrated and connected to a network. As a result, it is possible to improve the reliability when controlling a large fire engine, reduce the amount of wiring related to communication signals such as a wiring harness, and reduce the weight.

大型消防車両は、後輪操舵手段８を有することにより、その全長が長くても回転半径を比較的小さくすることができる。すなわち、大型消防車両が操向する方向に対し、逆方向に後輪を舵角する後輪操舵手段８を有するので、交差する幅員約９ｍの道路を略直角に曲がることができる。大規模な石油コンビナートや火力発電所等の工場内では、道路の幅員が約９ｍ以上に整備されているので、本発明の大型消防車両は、これら工場内をスムーズに走行することができる。また、車庫等への出入りも支障がない。 Since the large fire truck has the rear wheel steering means 8, the turning radius can be made relatively small even if the total length of the truck is long. That is, since it has the rear wheel steering means 8 that steers the rear wheels in the opposite direction to the steering direction of the large fire truck, it can turn at a substantially right angle on the crossing road with a width of about 9 m. In factories such as large-scale petroleum complexes and thermal power plants, roads are maintained with a width of about 9 m or more, so the large fire engine of the present invention can smoothly run in these factories. In addition, there is no problem in entering and exiting a garage or the like.

大型消防車両は、回転半径が最小になるように走行するとき、図４に示すように、操向方向の外側前輪が描く円の半径Ｒｏが１１ｍ以下、内側後輪が描く円の半径Ｒｉが７ｍ以下であるとよい。半径Ｒｏおよび半径Ｒｉをこのような範囲内にすることにより、石油コンビナート等の工場内を、スムーズに走行することができる。 When a large fire engine runs with the minimum turning radius, as shown in FIG. It is good in it being 7 m or less. By setting the radius Ro and the radius Ri within such ranges, it is possible to smoothly travel inside a factory such as a petroleum complex.

本発明の大型消防車両は、公道を走行可能に設計されている。
大型消防車両は、全長が約１１ｍ以上約１６ｍ以下であるとよく、全幅が約２．０ｍ以上約３．５ｍ以下であるとよく、全高が、塔４を収めた状態で、約２．５ｍ以上約５．０ｍ以下であるとよい。 The large fire engine of the present invention is designed to be able to travel on public roads.
The large fire engine should have a total length of about 11 m or more and about 16 m or less, a total width of about 2.0 m or more and about 3.5 m or less, and a total height of about 2.5 m when the tower 4 is included. It is good that it is more than about 5.0m or less.
