Description

The present invention relates to a fire hydrant device and a fire extinguisher box installed in a tunnel.

Conventionally, a fire hydrant device installed in a tunnel has been installed in a box-extracted portion where a main body for accommodating a fire extinguishing hose, a fire extinguisher, or the like is formed on an inner wall (see, for example, Patent Document 1).

JP-A-2015-44039

Tunnels in recent years are often constructed by the shield method. In the shield method, since the inner wall is constructed of steel segments at the same time as excavation, it is not possible to form a boxed portion on the wall surface as in the conventional method. In the case of tunnels constructed by such a shield method, the fire hydrant device is installed by placing the main body on the road surface of the audit road (provided between the inner wall and the roadway as being higher than the roadway), or the inner wall. It is installed on the wall of the wall in a wall-mounted manner.

By the way, in this kind of fire hydrant device, the fire extinguisher is conventionally stored in a low position in the main body such as being placed on the bottom of the main body and stored, but the storage position of the fire extinguisher is raised. May be done.

However, if the storage position of the fire extinguisher is raised, it may be difficult to remove the fire extinguisher from the main body. In particular, when the main body is installed on the wall, it is assumed that the storage position of the fire extinguisher will be higher than when it is installed on the audit road, and it may be more difficult to take it out. Even when the main body is installed on the audit road, if the storage position of the fire extinguisher is set too high, it may be difficult to take it out.

In the tunnel, a fire extinguisher may be stored and installed in a fire extinguisher box (also referred to as a "fire extinguisher storage box"). The fire extinguisher box also has the same problems as described above for the fire hydrant device.

In view of the above circumstances, it is an object of the present invention to obtain a fire hydrant device capable of easily taking out a fire extinguisher from the main body. It also aims to obtain a fire extinguisher box that can do so.

The present invention relates to a fire hydrant device including a box-shaped main body in which a fire extinguisher is housed together with a fire extinguishing hose, and a door for opening and closing an opening provided in front of a portion of the main body in which the fire extinguisher is housed. The fire hydrant device is characterized in that the door is provided with a lowering mechanism portion that moves the fire extinguisher downward by its own weight when the door is opened.

The present invention also relates to a fire extinguisher box comprising a box-shaped main body in which a fire extinguisher is housed and a door for opening and closing an opening provided in front of a portion of the main body in which the fire extinguisher is housed. The fire extinguisher box is characterized in that the door is provided with a lowering mechanism portion that moves the fire extinguisher downward by its own weight when the fire extinguisher is opened.

Here, in the fire hydrant device or the fire extinguisher box of the present invention, the lowering mechanism portion suspends a mounting portion on which the fire extinguisher is mounted and a mounting portion described above, which are provided on the back surface side of the fire extinguisher door. It has a holding portion to be held, and the fire extinguisher mounted on the above-mentioned mounting portion can be moved downward by extending the hanging portion downward. Further, the holding portion is a damper, and can control the downward moving speed of the fire extinguisher. Further, a stop portion in which the previously described placement portion of the lowering mechanism portion abuts against the inside of the main body and holds the front description placement portion at a height position when the fire extinguisher is housed inside the main body. Is provided, and the stop portion may be provided as forming the upper end portion of the inclined portion provided inside the main body so as to be inclined from the back surface side to the front surface side. Further, the main body is mounted on a wall surface in a wall-mounted manner, and in the lowering mechanism portion, when the fire extinguisher is moved downward, the previously described placing portion is located below the bottom portion of the main body. Can be moved to. Further, the main body has an inclined portion inclined inward on the back surface, and the fire extinguisher can be housed above the inclined portion.

In the present invention, even if the storage position of the fire extinguisher is raised, the fire extinguisher can be moved downward by the lowering mechanism portion when the fire extinguisher door is opened and the fire extinguisher is taken out.

Therefore, according to the present invention, it is possible to obtain a fire hydrant device from which a fire extinguisher can be easily taken out. You can also get a fire extinguisher box that can do so.

An example of the embodiment of the fire hydrant device of the present invention is shown, and is a front view of the entire fire hydrant device in a state where the door of the fire extinguisher storage unit is closed and the fire extinguisher is housed in the fire extinguisher storage unit. .. FIG. 1 is a cross-sectional view taken along the line AA of FIG. It is a figure corresponding to FIG. 1 in the state where the door is open and the fire extinguisher is moving downward. It is a top view of FIG. FIG. 3 is a cross-sectional view taken along the line AA of FIG. It shows an example of the installation mode of the above-mentioned fire hydrant device in a tunnel, and is an explanatory view when it is installed on the wall surface of the inner wall in a wall-mounted manner (the fire hydrant device is shown in the state of FIGS. 3 to 5). The internal structure on the tunnel side is not shown).

An embodiment of the present invention will be described with reference to the drawings as an example when applied to a fire hydrant device. The present invention can be applied not only to the fire hydrant device but also to the fire extinguisher box, and the configuration of the main body and the door in the example when applied to the fire hydrant device described below is the fire extinguisher box. It can also be applied to the main body and door of.

[overall structure]
As shown in FIGS. 1 to 5, the fire hydrant device 1 of the present invention has a box-shaped main body 2 in which a fire extinguisher 3 is housed together with a fire extinguishing hose (not shown). The main body 2 is provided with a hose storage unit (not shown) for storing a fire extinguishing hose, a fire extinguisher storage unit 2a for storing a fire extinguisher 3, and the like. Further, the main body 2 has a hose door 2b that opens and closes an opening (not shown) provided in front of the hose storage portion on the front surface (the side facing the roadway when installed in a tunnel), and a fire extinguisher storage portion 2a. A fire extinguisher door 2d or the like that opens and closes the opening 2c provided in front of the hose is provided.

If the fire hydrant device 1 is installed close to the wall surface of the shield tunnel as shown in the installation example of FIG. 6, the width of the lower portion may have to be narrowed in order to conform to the wall surface shape. In that case, since the fire extinguisher cannot be stored in the narrow portion, the fire extinguisher storage unit 2a is provided at a higher position from the lowermost portion of the fire hydrant device 1. Further, when the fire hydrant device 1 is wall-mounted, the lowermost part thereof is higher than the audit road surface, and even if the lowermost part of the fire extinguisher storage part 2a is the same height as the lowermost part of the fire extinguisher storage part 1, the fire extinguisher storage part 2a will be provided at a position higher than the audit road surface.

[Descent mechanism]
The fire hydrant device 1 functions as a support portion for supporting the fire extinguisher 3 in the fire extinguisher door 2d, and when the fire extinguisher door 2d is closed, the fire extinguisher device 1 is stored in a predetermined position in the fire extinguisher storage portion 2a. A lowering mechanism portion 4 that functions as a mechanism for moving the fire extinguisher 3 downward when the fire extinguisher door 2d is opened is provided.

Since the fire hydrant device 1 includes the lowering mechanism portion 4, even if the storage position of the fire extinguisher 3 is raised, when the fire extinguisher door 2d is opened and the fire extinguisher 3 is taken out, the lowering mechanism portion 4 is provided. The fire extinguisher 3 can be moved downward, and the fire extinguisher 3 can be easily taken out.

[Fire extinguisher storage position]
Here, the storage position of the fire extinguisher 3 when the fire extinguisher door 2d is closed (the position where the lowering mechanism unit 4 supports the fire extinguisher 3 in the fire extinguisher storage unit 2a) is the upper part inside the main body 2. The position is closer to the fire extinguisher 3 than when it is placed on the bottom inside the main body 2 to store the fire extinguisher 3 (see FIG. 2). When the fire extinguisher door 2d is opened, the lowering mechanism portion 4 can move the fire extinguisher 3 housed in such a high position downward.

[Each component of the lowering mechanism]
As shown in the overall details in FIG. 5, the lowering mechanism portion 4 includes a mounting portion 4a on which the fire extinguisher 3 is mounted and a damper 4b which is an example of a hanging portion for suspending the mounting portion 4a. When the fire extinguisher door 2d is opened, the weight of the fire extinguisher 3 and the mounting portion 4a causes the damper 4b to extend downward while moving the fire extinguisher 3 downward together with the mounting portion 4a.

-Mounting section The mounting section 4a is provided as a flat plate having a size that allows two fire extinguishers 3 to be placed side by side in the case of the illustrated example. .. The mounting portion 4a is provided with a frame-shaped support 4aa fixedly provided on the lower surface thereof in a direction extending in the width direction.

The strip plate and the side plate lowering mechanism portion 4 are fixed to the mounting portion 4a, and the strip plate 4ab provided continuously from the front end edge of the mounting portion 4a to both end edges in a U-shape and both side ends thereof. It further has side plates 4ac provided on each edge. These strips 4ab and side plates 4ac function to prevent the fire extinguisher 3 mounted on the mounting portion 4a from moving forward or sideways or falling over.

-Damper The damper 4b is provided on both the left and right sides of the mounting portion 4a so as to extend in the vertical direction along the back surface of the fire extinguisher door 2d, and the upper end of each cylinder portion 4ba is the fire extinguisher door 2d. The lower end of the piston portion 4bb that expands and contracts with respect to the cylinder portion 4ba is connected to the mounting portion 4a side, and the mounting portion 4a moves up and down along the back surface of the fire extinguisher door 2d. It is suspended as much as possible.

The damper 4b not only suspends the mounting portion 4a so as to be movable in the vertical direction, but also functions as a damper, and when the mounting portion 4a moves downward together with the fire extinguisher 3 by its own weight. Is also capable of controlling its movement speed.

The guide portion lowering mechanism portion 4 further includes a guide portion 4c that guides the vertical movement of the mounting portion 4a. The guide portions 4c are provided on both the left and right sides of the mounting portion 4a, respectively, along the fixed rails 4ca and the fixed rails 4ca which are fixedly provided along the back surface of the fire extinguisher door 2d in a direction extending in the vertical direction. It has a movable rail 4 kb that is movably provided and is fixedly provided to the side plate 4ac of the mounting portion 4a.

-Damper connection part The damper 4b is specifically connected to the guide rail 4ca in which the upper end portion of the cylinder portion 4ba is fixed to the fire extinguisher door 2d, and the lower end portion of the piston portion 4bb is mounted. It is connected to both ends of the support 4aa fixed to the portion 4a, respectively.

[Descent position of fire extinguisher]
In the case of the illustrated example, the lowering mechanism portion 4 moves until the mounting portion 4a on which the fire extinguisher 3 is mounted is located below the bottom 2e of the main body 2 when the fire extinguisher 3 is moved downward. The fire extinguisher 3 is provided so as to move the fire extinguisher 3 until the lower side is located below the bottom 2e of the main body 2. As a result, as will be described later, even when the main body 2 is mounted on the wall surface of the inner wall W of the tunnel T in a wall-mounted manner (see FIG. 6), the fire extinguisher 3 is lowered to a low position near the road surface of the audit road R2. The fire extinguisher 3 can be easily taken out.

[Fire extinguisher door opening / closing mechanism]
The fire extinguisher door 2d is provided as a sideways opening door around the vertical axis, and when opened, the lowering mechanism portion 4 provided on the back surface side is made to move the fire extinguisher 3 downward as described above. Functions as a thing.

[Means for stopping the lowering mechanism]
Inside the main body 2, when the fire extinguisher door 2d is closed, the fire extinguisher 3 descends as a means for holding the fire extinguisher 3 in a stored state located at a predetermined position in the fire extinguisher storage portion 2a. A stop means for stopping the operation of the mechanism unit 4 and holding the fire extinguisher 3 in the retracted state is provided.

As such a stopping means, in the case of the illustrated example, when the fire extinguisher 3 is in the retracted state, the front end side of the strip 4ab of the lowering mechanism portion 4 comes into contact with the lowering mechanism portion 4. A stop unit 4d for stopping the operation is provided (see FIG. 2).

When the fire extinguisher door 2d is opened, the lowering mechanism portion 4 automatically starts the lowering operation when the portion of the strip 4ab in contact with the stop portion 4d is separated from the stop portion 4d. ..

[Inclined part inside the main body]
Inside the main body 2, an inclined portion 4e forming an inclined surface inclined from the back side to the front side is provided below the fire extinguisher storage portion 2a. In the case of the illustrated example, the stop portion 4d is provided as forming the upper end portion of the inclined portion 4e (see FIG. 2).

Since the lowering mechanism portion 4 descends along the inclined portion 4e according to the opening degree of the fire extinguisher door 2d, the lowering mechanism portion 4 is caught inside the main body 2 and the fire extinguisher door 2d cannot be opened. Can be prevented. Further, when the holding of the fire extinguisher door 2d and the main body 2 is released and the mounting portion 4a reaches the inclined portion 4e from the stop portion 4d, the lowering mechanism portion 4 tries to descend, so that the fire extinguisher door 2d automatically opens. It opens and the descent of the descent mechanism unit 4 is completed.

[Inclined part on the back of the main unit]
The main body 2 is provided with an inclined portion 2f inclined inward in the lower portion on the back surface side, and a narrow portion 2g having a small depth dimension is provided inside the inclined portion 2f. The inclined portion 4e provided inside the main body 2 is provided in the narrow portion 2g. In the case of the illustrated example, it is assumed that the inclined portions 2f and 4e are inclined from the same position (the inclined portion 4e side is the position of the stopper 4d). The fire extinguisher storage portion 2a inside the main body 2 is provided above the inclined portions 2f and 4e (see FIG. 2).

[Advantages of having an inclined part on the back of the main body]
Since the main body 2 is provided with the inclined portion 2f, for example, when the fire hydrant device 1 is installed in the tunnel T, the main body 2 can be installed closer to the wall surface of the inner wall W, as will be described later. (See FIG. 6).

[Advantages of raising the storage position of the fire extinguisher]
Inside the main body 2, the fire extinguisher storage portion 2a is provided above the narrow portion 2g (inclined portion 2f). As a result, as shown in the illustrated example, the depth dimension inside the main body 2 in the portion where the fire extinguisher storage portion 2a is provided is reduced to a extent that slightly exceeds the outer diameter of the fire extinguisher 3, and the main body 2 is made thinner. However, the main body 2 can be provided with a narrow portion 2 g (inclined portion 2f). As described above, for example, when the fire extinguisher device 1 is installed in the tunnel T, the main body 2 can be provided. Can be installed closer to the wall surface of the inner wall W (see FIG. 6).

[Installation mode in tunnel]
As shown in FIG. 6, the fire hydrant device 1 may be installed on the wall surface of the inner wall W of the tunnel T in a wall-mounted manner, for example.

In the fire hydrant device 1, the storage position of the fire extinguisher 3 is raised, but as described above, when the door 4 is opened, the fire extinguisher 3 can be moved downward by the lowering mechanism portion 4. , The removal can be facilitated. In particular, as in the illustrated example, if the mounting portion 4a of the lowering mechanism portion 4 is to be moved until it is located below the bottom portion 2e of the main body 2, the main body 2 is hung on the wall surface of the inner wall W of the tunnel T. Even when the fire extinguisher 3 is installed in a formula, the fire extinguisher 3 can be lowered to a low position near the road surface of the audit tunnel R2, and the fire extinguisher 3 can be easily taken out.

Although not shown, the fire hydrant device 1 may be installed on the road surface of the audit road R2 of the tunnel T. In that case, the mechanism itself of the lowering mechanism portion 4 may be left movable downward until the mounting portion 4a is located below the bottom portion 2e of the main body 2, for example, with the bottom portion 2e of the main body 2. It may be movable downward to the same extent, that is, it may not be movable below the bottom 2e of the main body 2.

[Example of configuration change]
In the fire hydrant device 1 of the present invention, the configuration can be changed as follows, for example.

-Example of change of the suspension portion (damper) As the suspension portion for suspending the mounting portion 4a of the lowering mechanism portion 4, instead of the damper 4b described above, the mounting portion 4a is used together with the fire extinguisher 3 as in the damper 4b. You may use a torque reel that can control their descent speed while suspending them. In that case, the torque reel may be equipped with a ratchet mechanism so that the mounting portion 4a can be stopped at an arbitrary height position.

-Example of changing the stopping means of the lowering mechanism portion As the stopping means for stopping the operation of the lowering mechanism portion 4 and maintaining the state when the fire extinguisher 3 is in the retracted state, the above-mentioned stop portion 4d ( Instead of or in addition to providing the upper end portion of the inclined portion 4e), a holding member for holding the height position of the mounting portion 4a at the position when the fire extinguisher 3 is in the stored state is provided on the fire extinguisher door 2d side. You may do so. In that case, the holding state by the holding member can be released in conjunction with the operation of opening the fire extinguisher door 2d. Specifically, for example, the operation handle 4h of the fire extinguisher door 4 (see FIG. 1). It is possible that the holding state by the holding member is released in conjunction with the latch release operation by.

-Example of modification of the guide mechanism portion In the guide portion 4c, the ball bearing fixed to the side plate 4ac may move along the fixed rail 4ca as the moving mechanism with respect to the fixed rail 4ca.

-The tilting mechanism portion of the mounting portion After the lowering operation of the lowering mechanism portion 4, a tilting mechanism portion for tilting the mounting portion 4a on which the fire extinguisher 3 is mounted may be provided.
