  FIG. 2 is a front view showing the internal structure of the embodiment of FIG. 1 with the fire hydrant door 18 on the first housing 12-1 side removed and the maintenance door 22 opened upward and supported by a stay 27. In FIG. 2, a hose storage portion 36 is formed on the left side of the first housing 12-1, and a valve storage portion 38 is formed on the right side.

  At both lower corners of the door opening 16, there are provided buffer members 65 that abut the inner surface of the door when the fire hydrant door 18 is opened and slowly open the hydrant door 18.

  The hose storage portion 36 is arranged in a bucket frame 40 in which frame pipes are arranged vertically in the horizontal direction, forming a hose storage space inside. The bucket frame 40 is bent so that one pipe has a U-shape when viewed from the front and a horizontal L-shape when viewed from the plane, and the upper and lower pipe ends on the left side are formed on the left side surface of the first housing 12-1. It is fixed to the inner wall surface, and the right bent end is fixed to the inner wall surface on the rear surface of the housing by a frame holder 45.

  Two hose guides 42 are fixed in the center of the bucket frame 40 in the vertical direction, and a hose outlet is formed therein. When pulling out the hose 44, the hose guide 42 prevents the inner hose 44 from collapsing or rubbing against the door opening 16 to damage or break the hose 44.

  A hose 44 is housed inside the hose housing part 36 surrounded by the bucket frame 40 and the inner wall of the housing. Here, a hose connection port 46 is disposed at the lower part of the right side valve storage unit 38, and after the primary side of the hose 44 is connected to the hose connection port 46, the hose 44 is wound into the hose storage unit 36. However, in this case, the hose 44 is wound so that the hose 44 is wound clockwise when viewed from the door opening 16.

  That is, the hose 44 connected to the hose connection port 46 is first wound in the direction of the hose storage portion 36 along the lower inner wall of the first housing 12-1, and is wound from the lower side of the hose storage portion 36, and thereafter Nozzle holder that is wound clockwise into the storage unit and that finally has the nozzle 48 attached thereto is taken out from between the hose guides 42 attached near the center of the bucket frame 40 and attached to the lower bucket frame 40 A nozzle 48 is detachably attached to 50.

A water supply valve 52, a fire hydrant valve, an automatic pressure regulating valve, an automatic drain valve, and a maintenance device 60 are provided. Among these, a nameplate 66 is provided corresponding to the fire hydrant valve opening / closing lever 64 provided in the fire hydrant valve, and a fire hydrant valve, an automatic pressure regulating valve, and an automatic drain valve are arranged on the back side of the nameplate 66 and are not operated during the water discharge operation. Is hiding.

  The piping system arranged in the vertical direction is arranged from the right edge of the first housing 12-1, and the piping system is made inconspicuous when the fire hydrant door 18 is opened by approaching the end of the door opening 16. The components in the door opening 16 are refreshed.

  FIG. 3 is a side view showing the internal structure of FIG. 1 and shows the structure of the valve housing part. In FIG. 3, the fire hydrant door 18 in the closed state of the front surface of the first housing 12-1 can be opened to the illustrated forward position around the hinge 21 by releasing the latch by a handle operation.

  In this case, the fire hydrant door 18 is reduced in weight because it is not provided with a nozzle or a fire hydrant valve opening / closing lever, and it is not always necessary to provide a damper that absorbs an impact at the time of opening. It is only necessary to provide a buffer mechanism 65 such as a mechanism.

  In the valve storage unit 38, a water supply valve 52, a fire hydrant valve 54, an automatic pressure regulating valve 56, and a maintenance device 60 are continuously arranged in the vertical direction. The automatic drain valve 58 is mounted on the secondary side of the fire hydrant valve 54.

  The maintenance device 60 is provided with an inspection device insertion port 62.

That is, when the fire hydrant valve opening / closing lever 64 is in the closed position in the upward direction shown in the figure, the fire hydrant valve 54 is closed. At this time, there is no fire water in the pipe and there is no pressure, so the automatic drain valve 58 is open. It is in.

  When the fire hydrant valve opening / closing lever 64 is operated to the open position that faces downward, the fire hydrant valve 54 is operated to the open position, the pressure rises in the pipe, and the automatic drain valve 58 is operated to the closed position. As a result, the fire-extinguishing water pressurized from the water supply connection port 51 is regulated to a predetermined pressure through the automatic pressure regulating valve 56 and then supplied to the hose 44 side.

  At the same time, a switch installed behind the fire hydrant valve opening / closing lever 64 is turned on, whereby a signal is sent to the pump equipment and the pump equipment is started. When stopping the water discharge, returning the hydrant valve opening / closing lever 64 to the original upward position closes the hydrant valve 54 and simultaneously turns off the switch to stop the operation of the pump equipment.

  4 is a plan view showing the positional relationship between the suspension ring and the center of gravity in FIG. In FIG. 4, the first housing 12-1 and the second housing 12-2 are fixed by bolts and nuts at the connection fixing portion 15, and the position of the center of gravity G viewed from the plane as a whole is the first housing 12. -1 side.

  As is apparent from the internal structure of FIG. 2, a hose storage space 36 and a valve storage space 38 are formed on the first housing 12-1 side, and devices including a hose 44 and various valves are incorporated. The second casing 12-2 in which the fire hydrant storage unit 39 is formed depends on the fact that most of the weight of the entire apparatus is on the first casing 12-1 side.

  With respect to the center of gravity passing line 70 parallel to the front of the casing passing through the center of gravity G on the side of the casing 12-1, the suspension ring 25 is shifted by a distance ΔL in front of the apparatus as indicated by the suspension ring passage line 72. . The two suspension rings 25 are provided on the side of the casing 12-1 having a large size and weight.

  In order to balance the left and right when the casing is lifted, it is desirable to dispose the suspension ring at the same distance from the center of gravity G. In this case, the suspension ring is divided into the casing 12-1 and the casing 12-2. Will be placed.

  However, when the suspension ring is arranged separately in the case 12-1 and the case 12-2, when the crane is lifted by the crane, a load in the direction of bending the connection fixing part 15 is applied, and the connection fixing part is connected to the partition wall. Therefore, the strength is not so high, and there is a possibility of large distortion. Therefore, in the present embodiment, two suspension rings 25 are arranged on the housing 12-1 side so that a large load is not applied to the connection fixing portion 15 during lifting.

  FIG. 5 is a side view showing the positional relationship between the suspension ring and the center of gravity with respect to FIG. 1. Are shifted by a distance ΔL. Here, a hook provided at the end of the wire of the crane is engaged with the suspension ring 25, so that the point P at the upper end of the ring hole of the suspension ring 25 is the lifting point.

  FIG. 6 is a side view showing the posture of the fire hydrant device when FIG. 5 is lifted by a suspension ring. Assuming that a hook provided at the tip of the crane wire is hung on the suspension ring 25 of the fire hydrant device 10 and lifted at the point P, the fire hydrant device 12 when the center of gravity G comes on the vertical suspension line 80 passing through the lifting point P. The fire hydrant apparatus 10 is in an inclined posture in which the upper part of the casing approaches the tunnel wall surface side and the lower part of the casing is separated from the tunnel wall surface in this lifted stable state.

At this time, the inclination angle θ of the center-of-gravity passage line 74 that passes through the center of gravity G of the fire hydrant device 10 and is parallel to the front surface of the casing with respect to the suspension line 80 depends on the distance ΔL between the center-of-gravity passage line 74 and the suspension ring passage line 78 of FIG. If the distance in the vertical direction between the center of gravity G and the suspension point P is H,
θ = sin ⁻¹ (ΔL / H)
Therefore, by adjusting ΔL, the inclination angle θ can be adjusted to the optimum value.

  FIG. 7 is an explanatory view showing the installation work of the fire hydrant device according to the present invention. The fire hydrant device completed at the factory is loaded on the truck bed and transported to the tunnel construction site where it is installed for installation.

  A tunnel wall 82 is formed on the tunnel wall surface by unboxing, and the gantry 11 is installed on the bottom surface of the tunnel wall 82. The fire hydrant device 10 placed on the truck bed is engaged by the hook at the tip of the wire 86 to the suspension ring 25 and lifted by the crane 84, and as shown in the drawing, moves to the front side of the piercing portion 82 on the tunnel wall surface.

  However, since the boom of the crane 84 collides with the tunnel wall surface or a cable or equipment installed on the wall surface, it cannot be extended to the position directly above the punching-through portion 82 and moves to a position slightly ahead.

  At this time, as shown in FIG. 6, the fire hydrant device 10 has an inclined posture in which the upper part of the device approaches the tunnel wall surface and the lower part of the device is separated from the tunnel wall surface because the mounting position of the suspension ring 25 is shifted from the center of gravity G. It is in a lifted state.

  Next, for example, two workers are attached in front of the fire hydrant device 11 in the lifted state in the inclined posture, and the pendulum moves by pushing the fire hydrant device 11 toward the penetration part 82 while being lifted by the crane 84.

  When the hydrant device 10 is moved by the pendulum, the tilt angle of the hydrant device 10 is modified to change to a correct installation posture without tilting as the swing angle increases, that is, as the penetrating part 82 is approached. When this is done, the bottom of the apparatus changes to a correct installation posture substantially parallel to the gantry 11. When the pendulum is moved, the pendulum is moved while adjusting the length of the wire 86 so that the lower side of the fire hydrant device 10 does not hit the gantry 11. When the pendulum is moved onto the gantry 11, the wire 86 is loosened and placed on the gantry 11.

  Subsequently, the hook 86 is removed by loosening the wire 86 of the crane 84 with a part of the hydrant device 10 on the gantry 11, but the center of gravity G of the hydrant device 10 that has moved pendulum onto the gantry 11 when the hook is removed is It is located inside the tip of the gantry 11 or close to the tip of the gantry 11, and even if the wire 86 is removed, the force to fall outside is not so great, and it can be easily supported by the power of one or two workers. Can do.

  Subsequently, the fire hydrant device 10 is pushed into the pedestal 11 and positioned. Finally, anchor bolts are inserted into through holes provided in the bottom of the device and screwed into the screw holes of the pedestal 11 to complete the installation. .

  On the other hand, in the conventional installation work, as shown in FIG. 10, the fire hydrant device 100 is inclined and positioned on the gantry 102, and the center of gravity is outside the gantry 102. If it is not supported properly, it may fall, and there is a risk that it will have to be supported by 3 or 4 workers. However, in the present invention, the workers required for this installation work The safety is ensured by eliminating the risk of dropping when removing the fire hydrant device from the crane, and the installation work of the fire hydrant device can proceed efficiently and safely.

  FIG. 8 shows another embodiment of the fire hydrant device according to the present invention. In this embodiment, the upper surface position is shifted forward by a distance ΔL with respect to the center-of-gravity passing line 74 passing through the same center of gravity G as shown in FIG. In addition to the disposed suspension ring 25-1, the second suspension ring 25-2 is disposed at the position of the upper surface of the housing through which the center-of-gravity passage line 74 passes.

  FIG. 9 shows the unloading work using the second suspension ring 25-2. The fire hydrant apparatus 10 of this embodiment is carried in a state where the fire hydrant apparatus 10 is stacked and loaded on the truck bed, and the crane 84 is used to unload the fire hydrant apparatus 10 from the truck bed to the installation site. At this time, when lifting using the suspension ring 25-1 shifted forward from the position of the center of gravity, the fire hydrant device 10 tilts and rubs against the adjacent fire hydrant device 10 arranged on the loading platform, as shown in FIG. There is a risk of scratching the surface.

  Therefore, when unloading, as shown in FIG. 9, the adjacent fire hydrant device 10 is lifted by the crane 84 using the second suspension ring 25-2 provided corresponding to the position of the center of gravity. Unloading work can be performed without rubbing.

  In the above-described embodiment, the fire hydrant device having the divided structure of the first housing and the second housing is taken as an example, but the present invention can be applied as it is to the fire hydrant device of the housing integrated structure. Can do.

  Further, in the above embodiment having the divided structure of the first housing and the second housing, when two suspension rings are provided on the side of the first housing having a large size and weight and are lifted by a crane, In the case of the case integrated structure, two suspension rings are provided at equal distances on the left and right around the center of gravity of the case. It is desirable to balance left and right when lifted with
