Description

本発明は、放水ノズル付きホースを引き出して放水する消火栓装置に関する。
The present invention relates to a fire hydrant device that pulls out a hose with a water discharge nozzle to discharge water.

従来、高速道路や自動車専用道路などのトンネルに設置されるトンネル消火栓装置は、開放自在な消火栓扉を備えた筐体内に、ノズル付きホースとバルブ類を収納し、また、開閉自在な消火器扉を備えた消火器収納部に例えば２本の消火器を収納し、更に、通報装置扉が設けられ、ここに赤色表示灯、発信機、及び応答ランプを設けている。 Conventionally, tunnel fire hydrant devices installed in tunnels such as expressways and automobile roads contain a hose with a nozzle and valves in a casing equipped with an openable fire hydrant door, and a fire extinguisher door that can be opened and closed freely. For example, two fire extinguishers are housed in a fire extinguisher housing section provided with a notification device door, which is provided with a red indicator lamp, a transmitter, and a response lamp.

このような消火栓装置は火災を伴う車両事故の発生時に、消火栓扉を開いてノズル付きのホースを引き出し、消火栓弁開閉レバーを操作することで消火ポンプ設備を起動して放水を行うことができる。 Such a fire hydrant device can discharge water by opening a fire hydrant door, pulling out a hose with a nozzle, and operating a fire hydrant valve opening / closing lever when a vehicle accident involving a fire occurs.

従来の消火栓装置の筐体は前方に開いた箱形のユニットであり、筐体内部を隔壁により右側のホース収納空間とバルブ類収納空間と、左側の消火器収納空間とに分け、前面開口部に消火栓扉と消火器扉の扉開口を形成した１枚の化粧板を取り付けている。 The housing of a conventional fire hydrant device is a box-shaped unit that opens forward, and the inside of the housing is divided into a right hose storage space, a valve storage space, and a left fire extinguisher storage space by a partition, and a front opening A decorative plate with a door opening for the fire hydrant door and the fire extinguisher door is attached to the.

しかしながら、従来のトンネル消火栓装置にあっては、筐体にバルブ類、ノズル付きホース、消火器などの全ての機器を組込み配置し、更に、開閉自在な消火栓扉や消火器扉を設けていたため、装置全体として横幅が約２メートル、高さが約１メートル、奥行きが数十センチメートル、重量も数百キログラムといった大型のユニットとなり、組立を行った工場内での移動は勿論のこと、トンネル工事現場に搬送して設置する際にも、重量物として扱わなければならないことから大変であり、組立及び設置に手間と時間がかかるという問題がある。 However, in the conventional tunnel fire hydrant device, all devices such as valves, a hose with a nozzle, and a fire extinguisher are built in the housing, and furthermore, an openable fire hydrant door and a fire extinguisher door are provided. The entire device is a large unit with a width of about 2 meters, a height of about 1 meter, a depth of several tens of centimeters, and a weight of several hundred kilograms. Even when transported and installed on site, it is difficult because it must be handled as a heavy object, and there is a problem that assembly and installation take time and effort.

そこで近年にあっては、装置筐体を、消火栓ホース及びバルブ類を収納する筐体と、消火器を収納する筐体とに２分割した消火栓装置で構成し、筐体を２分割した消火栓装置は、架台の上に筐体を隣接配置した状態で合せ部分をボルトとナットなどにより連結固定する装置が提案されている。更に化粧板についても分割し、分割した筐体を連結固定した後に、分割した化粧板を各筐体の前面で面一となるように取り付けている。このように筐体を２分割にしたことにより、筐体や化粧板の一部が腐食等により交換が必要となった際には、分割した筐体もしくは化粧板のみの交換で済み、装置全体を交換するよりも費用を抑えることができ、また一つの筐体が軽量化、小型化することから作業効率を高めることができる。
Therefore, in recent years, a device housing is constituted by a fire hydrant device that is divided into a housing that houses a fire hydrant hose and valves and a housing that houses a fire extinguisher, and the fire hydrant device is divided into two. Has proposed a device for connecting and fixing the mating portions with bolts and nuts in a state in which the casing is disposed adjacent to the base. Further, the decorative plate is also divided, and the divided casings are connected and fixed, and then the divided decorative plates are attached so as to be flush with the front surface of each casing. By dividing the casing into two parts in this way, when part of the casing or the decorative board needs to be replaced due to corrosion or the like, it is only necessary to replace the divided casing or decorative panel, and the entire apparatus The cost can be reduced as compared with the replacement, and the work efficiency can be improved because one housing is reduced in weight and size.

しかしながら、このような筐体及び化粧板を分割した構造の消火栓装置にあっては、分割した筐体をネジ止固定により連結する際に、筐体の前後方向の位置決めが正確にできていないと、筐体前面に化粧板を取り付けたときに面一とならずに連結部分で段差が生じて見栄えが悪くなるとともに、装置前方のトンネルの監視員通路に化粧板が出っ張ることとなり危険である。また装置の設置そのものができなくなる可能性がある。 However, in such a fire hydrant device having a structure in which the casing and the decorative plate are divided, when the divided casings are connected by screwing and fixing, the positioning of the casing in the front-rear direction is not accurately performed. When the decorative plate is attached to the front surface of the casing, it is not flush and a step is produced at the connecting portion, which deteriorates the appearance, and the decorative plate protrudes in the observer passage of the tunnel in front of the device, which is dangerous. Moreover, there is a possibility that the installation of the apparatus itself cannot be performed.

また、筐体を分割構造とし、化粧板は従来通りの２筐体分の一枚物とした場合には、筐体の連結がおかしいと、化粧板が筐体に曲がって取り付けたり、筐体への取付そのものができない可能性がある。 In addition, when the case has a split structure and the decorative board is a single piece for two cases as before, if the case is not connected properly, the decorative board may be bent and attached to the case. There is a possibility that it cannot be attached to the camera itself.

本発明は、筐体を分割した構造であっても、分割筐体を容易に位置決めして設置できるようにする消火栓装置を提供することを目的とする。

At this time, since the connection surface of the second housing 12-4 is flat with respect to the connection surface of the first housing 12-1, even if the fire hydrant device is housed and disposed in the housing portion formed in the tunnel wall surface. Can be pulled out easily.

交換を必要とする新たな第２筐体１２−２の組付けは、第２筐体１２−２の連結面７４−２を第１筐体１２−１の連結面７４−１に位置合せして押し込むことで、容易に連結位置に第２筐体１２−２を収納することができ、この状態で図６に示したように、第２筐体１２−１の内部から位置決め棒１００を入れて位置決めした後にボルト８８を通して第１筐体１２−１と連結固定し、電気機器に対する信号線の接続が完了したら、最終的に新たな第２化粧板１４−２を取り付け固定して作業を完了する。 Assembling a new second housing 12-2 that requires replacement aligns the connecting surface 74-2 of the second housing 12-2 with the connecting surface 74-1 of the first housing 12-1. By pushing in, the second housing 12-2 can be easily stored in the connection position. In this state, as shown in FIG. 6, the positioning rod 100 is inserted from the inside of the second housing 12-1. After the positioning, the first casing 12-1 is connected and fixed through the bolt 88. When the connection of the signal line to the electrical equipment is completed, a new second decorative board 14-2 is finally attached and fixed. To do.

第１筐体１２−１を交換する場合は、第２筐体１２−２のフランジ部７６−２が第１筐体１２−１の矩形窪み部７２の前方に位置するため、先に第２筐体１２−２を取り外すか、可能であれば横にずらして、フランジ部７６−２が第１筐体に干渉しない位置にしてから第１筐体を取り外すこととなる。第１筐体１２−１を取り外す場合は、第１筐体上部に付けられた吊り輪２５を使用して第１筐体と第２筐体を共に架台から取り外した後に、筐体の分割作業及び連結作業を行っても良い。このように、本実施例においては、交換頻度と筐体重量を考慮して第２筐体１２−２を交換しやすく設定しているが、どちらの筐体の交換を行いやすくするかを適宜設定し、他方の筐体に矩形窪み部及び吊り輪を形成する。 When exchanging the first housing 12-1, the flange portion 76-2 of the second housing 12-2 is positioned in front of the rectangular recess 72 of the first housing 12-1, so The housing 12-2 is removed or shifted to the side if possible, and the first housing is removed after the flange portion 76-2 is positioned so as not to interfere with the first housing. When removing the first housing 12-1, after removing both the first housing and the second housing from the gantry using the suspension ring 25 attached to the upper portion of the first housing, the division work of the housing is performed. In addition, connection work may be performed. As described above, in the present embodiment, the second casing 12-2 is set to be easily replaced in consideration of the replacement frequency and the weight of the casing. However, which casing should be easily replaced is appropriately determined. Set, and form a rectangular recess and a suspension ring in the other housing.

ここで第１筐体１２−１の連結面７４−１側の前面開口コーナー部に形成された矩形窪み部７２に相対して、第２筐体１２−２のフランジ部７６−２の背後に位置決めブロック１０６を固定している。 Here, behind the flange portion 76-2 of the second housing 12-2, facing the rectangular recess 72 formed in the front opening corner portion on the connection surface 74-1 side of the first housing 12-1. The positioning block 106 is fixed.

位置決めブロック１０６は例えば筐体上下の２箇所に固定されており、位置決めブロック１０６の奥行き方向の長さＬは、第１筐体１２−１におけるフランジ部７６−１のフランジ面から矩形窪み部７２の窪み面までの距離Ｌと一致するようにしている。 The positioning block 106 is fixed, for example, at two locations above and below the housing, and the length L in the depth direction of the positioning block 106 is a rectangular recess 72 from the flange surface of the flange portion 76-1 in the first housing 12-1. It is made to correspond with the distance L to the hollow surface.

図１５は図１４の位置決めブロック１０６を用いて位置決めが完了した状態を平面で示した説明図であり、第２筐体１２−２のフランジ部７６−２の背後に固定した位置決めブロック１０６の後端が矩形窪み部７２の前方の窪み面に当接して両者を位置決めしており、この状態で第１筐体１２−１と第２筐体１２−２をボルト８８により連結固定する。位置決めブロック１０６は第１筐体１２−１の窪み部７２側に設けても良い。 FIG. 15 is an explanatory view showing a state in which the positioning is completed using the positioning block 106 of FIG. 14 in a plan view, after the positioning block 106 fixed behind the flange portion 76-2 of the second housing 12-2. Both ends are positioned by abutting against the hollow surface in front of the rectangular hollow portion 72, and in this state, the first housing 12-1 and the second housing 12-2 are connected and fixed by the bolt 88. The positioning block 106 may be provided on the recess 72 side of the first housing 12-1.

図１６は位置決めプレートを用いた位置決め構造の他の実施形態を取り出して平面で示した説明図であり、位置決め前の状態である。図１６において、第１筐体１２−１に対し第２筐体１２−２を横方向に位置合せして前方から第２筐体１２−２を矢印で示すように組み込んで連結する。 FIG. 16 is an explanatory view showing another embodiment of the positioning structure using the positioning plate and showing it in a plan view, and shows a state before positioning. In FIG. 16, the second housing 12-2 is aligned laterally with respect to the first housing 12-1, and the second housing 12-2 is assembled and connected from the front as indicated by an arrow.

ここで第１筐体１２−１の連結面７４−１側の前面開口コーナー部に形成された矩形窪み部７２にはＬ字形の位置決めプレート１０８が固定されている。 Here, an L-shaped positioning plate 108 is fixed to the rectangular recess 72 formed in the front opening corner of the first housing 12-1 on the connection surface 74-1 side.

位置決めプレート１０８は矩形窪み部７２における例えば上下の２箇所に固定されており、位置決めプレート１０８の前後方向の長さＬは、フランジ部７６−１の前面から矩形窪み部７２の前方の窪み面までの長さＬに一致するようにしている。 The positioning plate 108 is fixed at, for example, two locations in the rectangular recess 72 such as upper and lower, and the length L in the front-rear direction of the positioning plate 108 extends from the front surface of the flange portion 76-1 to the recess surface in front of the rectangular recess 72. It is made to correspond to the length L.

図１７は図１６の位置決めプレート１０８を用いて位置決めが完了した状態を平面で示した説明図であり、第１筐体１２−２の矩形窪み部７２に固定した位置決めプレート１０８の先端が、第２筐体１２−４のフランジ部７６−２の背面に当接して両者を位置決めしており、この状態で第１筐体１２−１と第２筐体１２−２をボルト８８により連結固定する。位置決めプレート１０８は第２筐体１２−２側面の連結面７４−２側に設けても良い。 FIG. 17 is a plan view showing a state in which the positioning is completed using the positioning plate 108 of FIG. 16, and the tip of the positioning plate 108 fixed to the rectangular recess 72 of the first housing 12-2 is The two housings 12-4 are positioned in contact with the rear surface of the flange portion 76-2 of the housing 12-4. In this state, the first housing 12-1 and the second housing 12-2 are connected and fixed by the bolts 88. . The positioning plate 108 may be provided on the connection surface 74-2 side of the side surface of the second housing 12-2.

図１８は位置決め構造の他の実施形態を取り出して平面で示した説明図であり、位置決め用部材の長さを調整可能としている。図１４の位置決めブロック１０６や図１６の位置決めプレート１０８は、長さＬの固定部材であるが、図１８は矩形窪み部７２内の筐体表面に穴を開口してナット１１１を溶接し、筐体内から位置決めボルト１０９を通してボルト１０９を回すことにより、フランジ７６−２側に突出するボルト先端のネジ部の距離Ｌの長さを調整できるようにしている。 FIG. 18 is an explanatory view showing another embodiment of the positioning structure in a plan view, in which the length of the positioning member can be adjusted. The positioning block 106 in FIG. 14 and the positioning plate 108 in FIG. 16 are fixed members having a length L. In FIG. 18, a hole is opened in the surface of the casing in the rectangular recess 72 and the nut 111 is welded. By rotating the bolt 109 through the positioning bolt 109 from the inside of the body, the length of the distance L of the screw portion at the tip of the bolt protruding to the flange 76-2 side can be adjusted.

これにより筐体毎の寸法誤差をボルトの長さに応じて調整することができ、両方の化粧板表面を面一にすることができる。ボルト１０９による長さ調整は初回設置時に一度決めれば、その後の交換時は先に設定したボルト位置に基づいて筐体の位置決めを容易に行うことができる。ボルト１０９の向きは、ボルトの頭部が矩形窪み部７２側にあっても良い。またボルトが直接にフランジ７６−２にあたる構成に限らず、ボルト先端にプレートなどフランジ７６−２裏面に当たる部材を備え、ボルトを回すと、先端のプレートが前後することで位置決めを調整できる位置決め構成としても良い。 Thereby, the dimensional error for every housing | casing can be adjusted according to the length of a volt | bolt, and both the decorative board surfaces can be made flush. Once the length adjustment by the bolt 109 is determined once at the time of initial installation, the casing can be easily positioned based on the previously set bolt position during subsequent replacement. The direction of the bolt 109 may be such that the head of the bolt is on the rectangular recess 72 side. In addition to the configuration in which the bolt directly hits the flange 76-2, a member that contacts the back surface of the flange 76-2 such as a plate is provided at the bolt tip, and when the bolt is turned, the positioning can be adjusted by moving the tip plate back and forth. Also good.

図１９は位置決め構造の他の実施形態を取り出して平面で示した説明図であり、分割した筐体を連結固定し、分割した化粧板を取り付ける前の状態を示している。図１９において、第１筐体１２−１及び第１化粧板１４−１は、前述した実施形態と同じであるが、第２筐体１２−２に形成したフランジ部７６−２の背面が第１筐体１２−１に形成した矩形窪み部７２に当接するように第２筐体１２−２の前面開口部のフランジ部７６−２を後退させた位置決め構造としている。 FIG. 19 is an explanatory view showing another embodiment of the positioning structure in a plan view, and shows a state before the divided casings are connected and fixed and the divided decorative plates are attached. In FIG. 19, the first housing 12-1 and the first decorative plate 14-1 are the same as in the above-described embodiment, but the back surface of the flange portion 76-2 formed on the second housing 12-2 is the first. The positioning structure is such that the flange portion 76-2 of the front opening of the second housing 12-2 is retracted so as to contact the rectangular recess 72 formed in the one housing 12-1.

このため第１筐体１２−１の奥行き長さＷに対し、矩形窪み部７２までの窪み長をＬとすると、第２筐体１２−２の奥行き寸法は（Ｗ−Ｌ）と短く設定されている。第２筐体１２−２の前方開口のフランジ部７６−２を後退したことに伴い、第２化粧板１４−２の背後に、第１化粧板１４−１の取付部材８５に比べ、フランジ部７６−２を後退させた寸法Ｌだけ長くした取付部材１０８を取り付けている。 For this reason, if the recess length to the rectangular recess 72 is L with respect to the depth length W of the first casing 12-1, the depth dimension of the second casing 12-2 is set to be short (W−L). ing. As the flange portion 76-2 of the front opening of the second housing 12-2 is retracted, the flange portion is behind the second decorative plate 14-2 compared to the attachment member 85 of the first decorative plate 14-1. A mounting member 108 that is elongated by a dimension L obtained by retracting 76-2 is attached.

また第１筐体１２−１のフランジ部７６−１と化粧板１４−１との間にはシール部材を配置させることが可能であるが、第２筐体１２−２と第２化粧板１４−２との間には隙間が形成されているためシール部材は配置しない。 Further, a seal member can be disposed between the flange portion 76-1 of the first housing 12-1 and the decorative plate 14-1, but the second housing 12-2 and the second decorative plate 14 are arranged. No seal member is disposed because a gap is formed between -2.

図２０は図１９について位置決めが完了した状態を平面で示した説明図であり、第１筐体１２−２における矩形窪み部７２の右側に、第２筐体１２−４のフランジ部７６−２の左端を当接させて両者を位置決めしており、この状態で第１筐体１２−１と第２筐体１２−２をボルトにより連結固定する。 FIG. 20 is an explanatory view showing the state in which the positioning is completed with respect to FIG. 19 in a plan view, and on the right side of the rectangular recess 72 in the first housing 12-2, the flange portion 76-2 of the second housing 12-4. Both are positioned by contacting the left end of the first housing 12-1 and the first housing 12-1 and the second housing 12-2 are connected and fixed with bolts in this state.

連結した第１筐体１２−１の前面には、第１化粧板１４−１が筐体側のボルト８６に対する取付部材８５の連結で図１０に示したように固定される。また、第２筐体１２−２の前面には、第２化粧板１４−２が筐体側のボルト８６に対し取付部材１１０の連結で固定されるが、取付部材１１０はフランジ部７６−２の後退寸法だけ長く作られているため、第２化粧板１４−２を第１化粧板１４−１に対し面一となる段差のない位置に取付固定することができる。 As shown in FIG. 10, the first decorative plate 14-1 is fixed to the front surface of the connected first housing 12-1 by connecting the attachment member 85 to the bolt 86 on the housing side. The second decorative plate 14-2 is fixed to the front surface of the second casing 12-2 by connecting the mounting member 110 to the casing-side bolt 86. The mounting member 110 is connected to the flange portion 76-2. Since it is made long only by the retraction dimension, the second decorative plate 14-2 can be mounted and fixed at a position having no step which is flush with the first decorative plate 14-1.

なお、上記の実施形態において、筐体と化粧板の間にシール部材を配置するか否かは、必要に応じて適宜に選択できる。 In the above embodiment, whether or not the seal member is disposed between the housing and the decorative plate can be appropriately selected as necessary.

また、上記の実施形態にあっては、第１筐体１２−１における連結側の前面開口コーナー部に窪み部７２を形成して連結部でのフランジ部の干渉をなくしているが、第１筐体１２−１の交換優先度を高くする場合は、第２筐体１２−２における連結側の前面開口コーナー部に窪み部を形成するようにしても良い。なお、両方の筐体に窪み部７２を形成して各化粧板の側面折り返し部がそれぞれの窪み部に入り、各化粧板の側面が連結面の直前で対向させることも可能であるが、上記実施形態のように一方の筐体にのみ窪み部を形成するよりも筐体の製作コスト及び納期が多くかかることになり、上記実施形態の方が製作においては有利である。 In the above embodiment, the recess 72 is formed in the front opening corner portion on the connection side in the first housing 12-1 to eliminate interference of the flange portion at the connection portion. In order to increase the exchange priority of the housing 12-1, a recess may be formed in the front opening corner portion on the connection side in the second housing 12-2. Although it is possible to form the recess 72 in both housings, the side folded portion of each decorative plate enters the respective recess, and the side of each decorative plate can be opposed immediately before the connecting surface. The manufacturing cost and delivery time of the casing are higher than the case where the hollow portion is formed only in one casing as in the embodiment, and the above embodiment is advantageous in manufacturing.

また、矩形窪み部７２はフランジ部や化粧板１４の側面が収納できる形状であれば、どのような形の窪み部であってもよい。 Moreover, the rectangular hollow part 72 may be a hollow part of any shape as long as the flange part and the side surface of the decorative plate 14 can be accommodated.

なお、上記の実施形態においては、各筐体それぞれに分割した化粧板を取り付けるようにしているが、これに限らず、一枚の化粧板で両方の筐体の前面に取り付けられる構成であっても、筐体のフランジ部を面一として連結でき、化粧板を筐体に水平に取り付けることが可能となる。 In the above-described embodiment, a separate decorative plate is attached to each case. However, the present invention is not limited to this, and a single decorative plate can be attached to the front surfaces of both cases. However, the flange portion of the casing can be connected to be flush with each other, and the decorative plate can be attached to the casing horizontally.

また本発明は、その目的と利点を損なうことのない適宜の変形を含み、更に上記の実施形態に示した数値による限定は受けない。
Further, the present invention includes appropriate modifications that do not impair the object and advantages thereof, and is not limited by the numerical values shown in the above embodiments.
