Description

【0001】
【産業上の利用分野】
本発明は、地上に展張された状態の送水ホースを移動車により効率的に回収する方法およびそれに使用する移動車に関する。
【0002】
【従来の技術】
大規模火災の場合には、湖沼、海等が数百メートル程度の場所にあれば、それを水源として多数本の送水ホース(消防ホース)を連結しながら火災現場に展張して消火にあたることができる。また、山火事等の大規模火災の消火システムとして、数キロメートル離れた湖沼や海等の水源から、多数本の送水ホースを連結しながら火災現場まで延設して消火作業にあたるようにすることもある。
【0003】
このように消火作業開始時に送水ホースを数百メートルから数キロメートルにわたり展張したり、また消火作業終了後に回収したりする手段として、例えば図4に示すようなホースコンテナーを有する移動車が使用される。
図4の移動車は、車体1に運転台2とホースコンテナー3とをそれぞれ前後に配置し、ホースコンテナー3内の巻取リール11に送水ホースHを巻回格納するようにしたものである。消火作業開始時に、水源から火災現場まで送水ホースHを展張するときは、移動車を前方Fへ前進させながら巻取リール11から送水ホースHを解除しつつ車体後部から地上に放出し、逆に、消火作業終了のちに送水ホースHを回収するときは、移動車を後方Rへ後進させながら巻取リール11に巻き上げるようにしている。
【0004】
しかし、上記移動車による作業は、送水ホースを展張する場合には特に支障はないが、回収する場合は、車両を後進させながら作業するため、運転台2から地上の送水ホースHを確実に確認することが難しく、必然的に車両の移動速度が遅くなって、作業能率が低下してしまうという問題があった。また、後進での作業であるため安全性にも問題があった。
【0005】
【発明が解決しようとする課題】
本発明の目的は、消火作業終了後に地上に放置された送水ホースの移動車による回収作業を効率よく行える回収方法と、その作業に使用する移動車を提供することにある。
【0006】
【課題を解決するための手段】
本発明による送水ホース回収方法は、車体前部に運転台を設け、その後部にホースコンテナーを設け、かつ該ホースコンテナーの前部中央部にホース引込機構の格納庫を設けた移動車を使用し、前記格納位置から前記ホース引込機構を左右両端部のいずれか一方に選択的に移動してセットし、該移動車を地上に展張された送水ホースに沿って前進させながら、該送水ホースを前記ホース引込機構により引き上げて前記ホースコンテナに格納することを特徴とするものである。
【0007】
このように本発明によれば、運転台の作業者が車両を前進させながら送水ホースを回収するので、地上に展張された送水ホースの確認を容易に行うことができ、それに伴って車両速度を速くすることができるため作業効率を向上することができる。また、前方を視認しながら作業するので安全性も向上する。
また本発明は、前記ホースコンテナー前部の中央部を前記ホース引込機構の格納位置にし、送水ホースを引き上げ操作するとき該格納位置から前記ホース引込機構を左右両端部のいずれか一方のセット位置に選択的に移動するようにしている。
【0008】
したがって、送水ホースが路上において左右いずれ側に片寄って展張されていても、ホース引込機構をその片寄った側に移動させることにより円滑な回収作業を行うことができる。特に運転席側に移動させた場合には、運転者が送水ホースを最も確認しやすい位置で作業することになるので、作業性を一層向上することができる。
【0009】
また本発明は、前記ホース引込機構の構成として、駆動ローラとニップローラからなる組ローラを前後2段に配置し、各組ローラの前側にそれぞれ送水ホース接続金具の通過を検知するセンサーを配置する構成にし、前記2段の組ローラの各ニップローラを前記送水ホース接続金具の通過時間に対応させて時間差をおいて順次開閉させるようにしている。
【0010】
したがって、送水ホースを引き込む時のニップローラの押圧作用により、送水ホース内に残存する水をホースコンテナー内に持ち込まないように排除することができ、しかも前後2段の組ローラのニップローラが時間差をおいて開閉するようにしているため、送水ホースの接続金具が通過するときにも確実に水を排除しながら通過を可能にすると共に、中断することなく連続的な引き込みを可能にする。
【0011】
【実施例】
以下、本発明を図に示す実施例を参照して具体的に説明する。
図1および図2は、本発明による消防用の送水ホース回収方法を実施する移動車について例示するものである。
この移動車は、車体1の前部に運転台2を設け、その後部にホースコンテナー3を設け、さらにホースコンテナー3の前部にホース引込機構4を設けている。このホース引込機構4は、移動車が送水ホース(消防ホース)の回収作業をしないときは、ホースコンテナー前部中央の格納庫5の中に鎖線で示すように下降した位置に格納され、送水ホース(消防ホース)の回収作業をするときは、上部に上昇すると共に左右両端部のいずれか一方に移動し、その端部にセットされるようになっている。かつ、ホース引込機構4は、そのセット位置で後部側を車両進行方向に対して0°〜60°、好ましくは0°〜30°の範囲内に内向きに傾動可能になっている。
【0012】
図3に示すように、ホース引込機構4は、駆動ローラ41と上下に開閉するニップローラ41’からなる組ローラと、駆動ローラ42と同じく上下に開閉するニップローラ42’からなる組ローラとを前後2段に配置し、かつ各組ローラの前側にそれぞれ送水ホースHの接続金具Mを検知するセンサー43,44を配置して構成されている。センサー43,44は、送水ホースの接続金具Mが当接したとき揺動することによりその通過を検知するようになっている。
【0013】
駆動ローラ41,42は図示しないモータ等により積極駆動され、またニップローラ41’,42’は油圧シリンダーや電気的駆動方式によって上下に開閉作動するようになっている。センサー43,44としては、図示した揺動式のものに限定されるものではなく、光センサー、金属探知センサー、リミットスイッチ、感圧センサー、音波センサーなど公知のものがいずれも使用可能である。
【0014】
上記センサー43,44の検知信号により、制御部(図示せず)を介してそれぞれ各組ローラのニップローラ41’,42’が時間差をもって上方へ開き、接続金具Mを順次通過させるようにする。すなわち、2段の組ローラは、前後に間隔をおいて配置されているため、まず前側のセンサー43が接続金具Mの通過を検知すると、前側の組ローラのニップローラ41’が開いて接続金具Mを通過させ、次いで後側のセンサー44が接続金具Mの通過を検知し、後側の組ローラのニップローラ42’を開いて接続金具Mを通過させる。
【0015】
このように前後2段の組ローラのニップローラ41’,42’は時間差をもって順次開くため、一方が開いているときは、必ず他方が閉じた状態になるようにして、送水ホースHを中断することなく確実に連続的に搬送する。また、このニップローラ41’,42’は、上記搬送作用と共に送水ホースHを押圧するため、この押圧作用により内部に残存していた水を押し出し、ホースコンテナー3内に持ち込まないようにしている。
【0016】
上述した本発明の移動車を使用して、消火作業後(或いは消火訓練後)に水源と火災現場との間に残置された送水ホースHを回収するときは、まず送水ホースHが路上で左右いずれ側に片寄った放置状態になっているかを確認し、次いで格納庫5に格納されたホース引込機構4をホースコンテナー3の上端部へ上昇させ、そこからホースコンテナー3の左右両端部のセット位置のうち、路上の送水ホースHが片寄った側に移動させると共に、後端部側を車両進行方向に対してやや内向きに傾斜させる。好ましくは、運転席側の端部に移動させるとなお良い。
【0017】
ホース引込機構4を上記のように端部位置にセットした移動車を路面に沿って前方Fに前進させながら、そのホース引込機構4により送水ホースHを引き上げつつホースコンテナ3内に回収する。
ホースコンテナ3内への回収は、ホースコンテナ3内に入った別の作業者がホース引込機構4から送り出される送水ホースHを前後方向に往復させながら折り畳み、さらに左右方向にも変位させて、所謂島田巻きの積層状態にする。このような折り畳み作業をするに当たり、ホースコンテナ3内の作業者は車両の前進速度を確かめながらホース引込機構4の駆動ロール41,42を停止させたり、駆動させたりして調整することができる。
【0018】
このように車両を前進させながら送水ホースを回収するため、運転台2の作業者は地上に展張された送水ホースの位置の確認が容易になり、それによって車両速度を速くすることができる。したがって、送水ホースの回収作業効率は著しく向上する。
また、ホース引込機構4をホースコンテナ3の左右両端部のいずれか一方の位置にセットすることにより、好ましくは運転席側にセットすることにより、路上の送水ホースの放置状況に応じた引込み作業を容易にする。また、ホース引込機構4をセット位置において後部側をやや内側に斜め向けることにより、ホースコンテナ3内への送水ホースの折り畳み作業を効率よく行うことができる。このときの内側への傾斜角度としては、車両進行方向に対して0°〜60°、好ましくは0°〜30°の範囲にするとよい。
【0019】
なお、上記移動車は、もちろん消火作業の開始時に行う送水ホースの展張作業にも使用することができる。この送水ホースの展張作業は、従来と同様にホースコンテナー3の後部から路上に放出するようにして展張させればよい。
また、上述した実施例では消防用のホースの場合について説明したが、本発明のホース回収方法および移動車は、消防以外の例えば渇水時や地震発生時等において、遠隔地の水源から送水ホースを展張して水を供給するような場合における送水ホースの回収等にも適用することができる。
【0020】
【発明の効果】
上述したように、本発明によれば、運転台の作業者が車両を前進させながら送水ホースを回収するので、地上に展張された送水ホースの確認が容易になり、車両速度を可及的に速くすることができ、それによって回収作業効率を向上することができる。また、前方を視認しながら作業することができるので安全性も向上する。

[Industrial application fields]
The present invention relates to a method for efficiently collecting a water supply hose in a state of being spread on the ground, and a mobile vehicle used for the method.
[0002]
[Prior art]
In the case of a large-scale fire, if there are lakes, seas, etc. in a place of several hundred meters, it can be used as a water source and connected to a number of water hoses (fire hoses) to be deployed at the fire site to extinguish the fire. it can. In addition, as a fire extinguishing system for large-scale fires such as forest fires, it is possible to extend fireworks from a water source such as a lake or ocean several kilometers away to the fire site by connecting many water hoses. is there.
[0003]
As described above, for example, a mobile vehicle having a hose container as shown in FIG. 4 is used as a means for extending the water supply hose over several hundreds of meters to several kilometers at the start of the fire fighting operation, or collecting it after the fire fighting operation is completed. .
The moving vehicle shown in FIG. 4 is configured such that a cab 2 and a hose container 3 are respectively arranged on the front and rear of a vehicle body 1 and a water supply hose H is wound and stored on a take-up reel 11 in the hose container 3. When the water hose H is extended from the water source to the fire site at the start of the fire fighting operation, the water hose H is released from the take-up reel 11 to the ground while the moving vehicle is moved forward F, and released to the ground. When the water supply hose H is collected after the fire extinguishing operation is completed, the mobile vehicle is wound up on the take-up reel 11 while moving backward to the rear R.
[0004]
However, the above-mentioned work by the moving vehicle is not particularly troublesome when the water supply hose is extended, but when collecting, the work is carried out while moving the vehicle backward, so the water supply hose H on the ground is surely confirmed from the cab 2. It is difficult to do so, and the moving speed of the vehicle is inevitably slowed down, so that there is a problem that work efficiency is lowered. There was also a problem with safety because it was a backward work.
[0005]
[Problems to be solved by the invention]
The objective of this invention is providing the collection method which can perform efficiently the collection | recovery operation | work by the moving vehicle of the water supply hose left on the ground after completion | finish of fire extinguishing operation | work, and the moving vehicle used for the operation | work.
[0006]
[Means for Solving the Problems]
The water supply hose recovery method according to the present invention uses a mobile vehicle in which a driver's cab is provided at the front part of the vehicle body, a hose container is provided at the rear part thereof, and a hangar of the hose retracting mechanism is provided at the front center part of the hose container, The hose retracting mechanism is selectively moved from the storage position to either one of the left and right ends, and the water supply hose is moved forward along the water supply hose extended on the ground. The hose container is pulled up by a retracting mechanism and stored in the hose container.
[0007]
Thus, according to the present invention, the operator of the driver's cab recovers the water supply hose while moving the vehicle forward, so that the water supply hose extended on the ground can be easily confirmed, and the vehicle speed is accordingly increased. Since the speed can be increased, work efficiency can be improved. In addition, safety is improved because the work is performed while visually checking the front.
In the present invention, the central portion of the front portion of the hose container is set to the retracted position of the hose retracting mechanism, and when the water supply hose is pulled up, the hose retracting mechanism is moved from the retracted position to either one of the left and right end positions. It is designed to move selectively.
[0008]
Therefore, even if the water supply hose is extended to the left or right side on the road, smooth recovery work can be performed by moving the hose retracting mechanism to the offset side. In particular, when moved to the driver's seat side, the driver works at a position where the driver can most easily check the water supply hose, so that workability can be further improved.
[0009]
Further, according to the present invention, as the configuration of the hose retracting mechanism, the assembly rollers including the driving roller and the nip roller are arranged in two stages in the front and rear, and a sensor for detecting the passage of the water supply hose connection fitting is arranged on the front side of each assembly roller. The nip rollers of the two-stage assembled rollers are sequentially opened and closed with a time difference corresponding to the passage time of the water supply hose connection fitting.
[0010]
Therefore, it is possible to exclude the water remaining in the water supply hose from being brought into the hose container by the pressing action of the nip roller when the water supply hose is pulled in, and the nip rollers of the two-stage assembled rollers in the front and rear have a time difference. Since it opens and closes, even when the fitting of the water supply hose passes, it allows passage while reliably removing water, and allows continuous pull-in without interruption.
[0011]
【Example】
Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.
FIG. 1 and FIG. 2 exemplify a mobile vehicle that implements the water hose recovery method for fire fighting according to the present invention.
In this moving vehicle, a cab 2 is provided at the front of the vehicle body 1, a hose container 3 is provided at the rear thereof, and a hose retracting mechanism 4 is provided at the front of the hose container 3. The hose retracting mechanism 4 is stored in a lowered position as shown by a chain line in the hangar 5 at the front center of the hose container when the moving vehicle does not collect the water hose (fire hose). When the fire hose is collected, it rises to the top and moves to either one of the left and right ends, and is set to that end. In addition, the hose retracting mechanism 4 can tilt inwardly within the range of 0 ° to 60 °, preferably 0 ° to 30 ° with respect to the vehicle traveling direction on the rear side at the set position.
[0012]
As shown in FIG. 3, the hose pulling mechanism 4 includes a driving roller 41 and a pair of rollers including a nip roller 41 ′ that opens and closes up and down, and a pair of rollers including a nip roller 42 ′ that opens and closes up and down like the driving roller 42. Sensors 43 and 44 that detect the connection fitting M of the water supply hose H are arranged on the front side of each pair of rollers and arranged on the front side. The sensors 43 and 44 are configured to detect the passage by swinging when the connection fitting M of the water supply hose H comes into contact therewith.
[0013]
The drive rollers 41 and 42 are positively driven by a motor (not shown) or the like, and the nip rollers 41 ′ and 42 ′ are opened and closed up and down by a hydraulic cylinder or an electric drive system. The sensors 43 and 44 are not limited to the swing type shown in the figure, and any known sensor such as an optical sensor, a metal detection sensor, a limit switch, a pressure sensor, or a sound wave sensor can be used.
[0014]
Based on the detection signals of the sensors 43 and 44, the nip rollers 41 ′ and 42 ′ of the respective sets of rollers are opened upward with a time difference via a control unit (not shown), and the connection fitting M is sequentially passed. That is, since the two-stage assembled rollers are arranged at intervals in the front-rear direction, first, when the front sensor 43 detects the passage of the connection fitting M, the nip roller 41 ′ of the front combination roller is opened and the connection fitting M is opened. Then, the rear sensor 44 detects the passage of the connection fitting M, opens the nip roller 42 'of the rear roller assembly, and passes the connection fitting M.
[0015]
As described above, the nip rollers 41 ′ and 42 ′ of the two-stage assembled rollers of the front and rear are sequentially opened with a time difference. Therefore, when one of the rollers is open, the water hose H is interrupted so that the other is always closed. It conveys reliably and continuously. Further, since the nip rollers 41 ′ and 42 ′ press the water supply hose H together with the transporting action, the water remaining inside is pushed out by the pressing action and is not brought into the hose container 3.
[0016]
When using the above-described mobile vehicle of the present invention to collect the water hose H left between the water source and the fire site after the fire extinguishing work (or after fire training), the water hose H is first left and right on the road. Check which side is left unattended, then lift the hose retracting mechanism 4 stored in the hangar 5 to the upper end of the hose container 3, and from there set position of the left and right ends of the hose container 3 Among them, the water supply hose H on the road is moved to the side where the water hose is offset, and the rear end side is inclined slightly inward with respect to the vehicle traveling direction. Preferably, it is better to move to the end on the driver's seat side.
[0017]
While the moving vehicle having the hose retracting mechanism 4 set at the end position as described above is advanced forward F along the road surface, the water hose H is pulled up by the hose retracting mechanism 4 and collected in the hose container 3.
The recovery into the hose container 3 is performed by another worker entering the hose container 3 folding the water supply hose H sent out from the hose retracting mechanism 4 while reciprocating in the front-rear direction, and further displacing in the left-right direction. Make the Shimada roll stacked. When performing such a folding operation, an operator in the hose container 3 can make adjustments by stopping or driving the drive rolls 41 and 42 of the hose retracting mechanism 4 while checking the forward speed of the vehicle.
[0018]
Since the water hose is collected while moving the vehicle forward in this way, the operator of the cab 2 can easily confirm the position of the water hose extended on the ground, thereby increasing the vehicle speed. Therefore, the collection work efficiency of the water supply hose is remarkably improved.
Further, by setting the hose pulling mechanism 4 at either one of the left and right ends of the hose container 3, preferably by setting the hose pulling mechanism 4 on the driver's seat side, the pulling operation according to the leaving condition of the water supply hose on the road can be performed. make it easier. Further, the hose pulling mechanism 4 can be efficiently folded into the hose container 3 by turning the rear side slightly obliquely inward at the set position. The inward inclination angle at this time may be in the range of 0 ° to 60 °, preferably 0 ° to 30 ° with respect to the vehicle traveling direction.
[0019]
In addition, the said mobile vehicle can be used also for the extension work of the water supply hose performed at the time of the start of fire fighting work. The operation of extending the water supply hose may be performed by releasing it from the rear part of the hose container 3 onto the road as in the conventional case.
Further, in the above-described embodiment, the case of a fire hose has been described. However, the hose collection method and the mobile vehicle of the present invention can be connected to a water supply hose from a remote water source, for example, in the event of drought or an earthquake. The present invention can also be applied to collection of a water supply hose in the case where water is supplied by stretching.
[0020]
【The invention's effect】
As described above, according to the present invention, since the operator of the cab collects the water supply hose while moving the vehicle forward, it is easy to check the water supply hose extended on the ground, and the vehicle speed is made as much as possible. It can be made faster, thereby improving the recovery work efficiency. In addition, safety can be improved because the user can work while visually checking the front.
