[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire-extinguishing hose car used in the event of a fire, for example, by connecting to a fire engine supplied with water from an outdoor fire hydrant.

[0002]

BACKGROUND ART Generally, a fire engine is dispatched when a fire occurs, water is supplied to this fire engine from a fire hydrant closest to the fire occurrence site, and workers extend a fire hose from the fire engine to the fire occurrence site to discharge water or Fire fighting by foam injection. Especially in petroleum complexes, fire hydrants are installed along the main road at intervals of approximately 70 meters, and the fire hydrant closest to the fire occurrence site is used for fire extinguishing. At this time, until the hose is extended and water is released, a method using a backpack, a method called hand-shrinking,
It is also known that the method is performed by a method using a transport vehicle or the like.

That is, in the method using a backpack, a predetermined number of fire-extinguishing hoses are connected to and housed in a backpack-type appliance, and a fire-extinguishing worker carries the backpack-type appliance and simultaneously extinguishes the fire. The nozzle is connected to the hose and the turret is carried in hand, and the hose is extended. After the hose is extended, the fire-extinguishing worker connects the hose and the nozzle, and continuously fixes them to the turret to perform the fire-extinguishing operation.

[0004] In the hand-stopping method, a worker first extends and transports a predetermined number of fire hoses of a predetermined length from a place where the fire engine stops, while sequentially connecting them by a predetermined number. Next, the worker transports the nozzle and the turret to a predetermined place again, and connects the nozzle to the hose.
After that, the fire fighting worker fixed the nozzle to the turret to carry out fire fighting.

Further, in the method using a transport vehicle or the like, a nozzle is attached to a storage box in which a hose or the like is stored, and a turret support plate or the like for separately supporting a turret is provided, and these are connected to a fixed frame with wheels. In this case, the worker is transporting the whole to a predetermined place.

[0006]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional method using a backpack, the fire-extinguishing worker carries a device containing a plurality of fire-extinguishing hoses, and holds a nozzle and a turret in his hand. You must go close to the site of the outbreak. In order for one fire fighter to make such preparations, if the hoses are heavy and the carrying distance is long,
There is a transport problem that people who are not confident physically can not do so due to severe fatigue.

In particular, in order to extinguish a fire as soon as possible, preparations for water discharge must be rushed.
I have to run and be in a hurry. In this case, the fatigue becomes even more severe. As a result, it takes a long time to prepare for fire extinguishing work, which hinders quick initial fire extinguishing activities.

[0008] In this case, if the fire extinguishing workers carry the hoses and the like in a shared manner, there is not much fatigue. However, this causes another problem that many workers are required.

[0009] In the above hand-stopping method, a worker must first extend a predetermined number of fire-extinguishing hoses from the place where the fire engine stops, and transport the fire ex- tenders to the vicinity of the fire occurrence site. After carrying the hose, the worker again carried the nozzle and turret from the fire engine to the last hose position,
These must be combined. As described above, the preparation for the fire extinguishing operation is troublesome and time-consuming, and hinders the speeding up of the initial fire extinguishing activity as in the method using the backpack. Further, since a large amount of labor is required, the degree of fatigue is further increased.

Further, in the above-described method using a transport vehicle, since the storage box, the turret support plate, the fixed frame, and the like are separately provided, the entire apparatus becomes large. As a result, there is a problem that the weight becomes heavy and it is difficult to carry, and a large number of fire trucks cannot be provided.

It is an object of the present invention to provide a fire extinguisher hose car which is compact, can be mounted on a large number of fire engines, can be prepared for fire extinguishing in a short time, and has a low degree of fatigue.

[0012]

According to the present invention, a base, wheels provided on the base, and a base provided on the base so as to be openable and closable form a frame when closed and open when closed. A plurality of turret legs that can be locked to the ground surface, a turret main body provided on the base so as to be able to adjust the undulation angle, a fire extinguishing nozzle detachably connected to a tip side of the turret main body, A fire hose for fire extinguishing comprises a fire extinguisher hose detachably connected to the rear end side of the main body and connected to the fire hydrant and housed in the framework of the turret leg.

[0013]

According to the present invention, a frame is formed when a plurality of turret legs provided on the base are closed, and a fire extinguishing hose is stored in the frame. A base equipped with a plurality of turret legs, a turret body, a fire extinguishing nozzle, a fire extinguishing hose, and the like constitutes a compact fire extinguishing hose car equipped with wheels. Pull to move nearby.

As described above, since the turret body, the fire extinguishing nozzle, and the fire extinguishing hose are combined in advance and attached to the base to constitute a fire extinguishing hose car, the fire extinguishing hose car is compact, and accordingly, Can be installed in many fire trucks. Further, the base is provided with wheels and can be moved only by pulling the base, so that a fire extinguishing hose or the like can be easily transported. In addition, since the base can be fixed simply by opening the turret legs after moving to the predetermined position and locking the turret legs to the ground surface, operation is easy, and fire extinguishing preparation can be performed in a short time. Thereby, the above object is achieved.

Next, the operation of this embodiment will be described. The fire-extinguishing hose car 1 of the present embodiment has a fire-extinguishing hose 7 and a fire-extinguishing nozzle 8 previously attached to a turret body 6 as shown in FIG.
The fire extinguishing hose 7 is housed in a frame composed of a front leg 40, a rear leg 41 and the like. A plurality of such fire extinguisher hose cars 1 are installed on both side steps and rear steps of the fire engine. At this time, the fire-extinguishing hoses 7 are respectively connected to the discharge ports of the fire engine.

When the fire engine was fired and the fire engine arrived at the fire site, a plurality of fire fighting workers fired a fire hydrant near the fire site among the fire hydrants provided along the main road. Connect the car connection and supply water from the hydrant to the tank. Next, each worker unloads the fire hose car 1 from the fire engine, pulls the handle 93 in his hand, and moves the fire hose car 1 to the fire site.

When the worker pulls and moves the fire extinguisher hose 1 to the fire site, the fire extinguisher hose 7 is sequentially pulled out of the framework of the hose car 1. Fire hose 7
When all of them are pulled out, the worker determines the position of the hose car 1 in such a state that the water discharge port or the radiation port of the fire extinguishing nozzle 8 faces the fire occurrence part. In that state, the engagement hole of the rear leg 41
The connection between the front leg 40 and the rear leg 41 is released by pulling up the leg connecting rod 54 locked in the inside of 41B.

Then, the two rear legs 41, 41 rotate and fall with the mounting bolt 46 of the oblique plate 27 as a fulcrum. Then, the rear legs 41, 41 are fixed by projecting the protruding portion 41A at the tip thereof into the ground surface.

In the same manner as the movement of the rear leg 41, the rear leg 41 rotates and falls with the mounting bolt 44 of the front leg support bracket 23 as a fulcrum. Then, the front leg 40 is fixed by the protrusion 40A at the tip thereof piercing the ground surface.

At this time, the notch 43A of the stopper 43 attached to the rear leg 41 is rotated by the rotation of the stopper 43 so that the spring-biased rear leg fixing pin 47 is moved to the notch 43A.
Stopper 42 that engages 43A and is attached to the front leg 40
The notches 42A also engage with the front leg fixing pins 45, respectively. The engagement between the notches 42A and 43A and the fixing pins 45 and 47 causes the wheel 3 to slightly lift off the ground surface, thereby securely fixing the entire hose car 1 (see FIG. 9).

Next, the worker operates the lock pin 58 of the gun body 6.
, The angle of the turret main body 6 is adjusted so that water discharge or radiation from the nozzle 8 is optimized, and the lock pin 58 is released at that position. The turret main body 6 is fixed by engaging with the engaging hole 61A (see FIG. 9).

Thereafter, another worker starts water supply on the fire engine side, and the worker adjusts the angle of the turret main body 6 as appropriate.
Always ensure that optimal water discharge or radiation occurs.

According to the above-described embodiment, the following effects can be obtained. That is, the fire extinguishing hose 7 is incorporated in the turret body 6 in advance, and is stacked on the holding plate 30 while being supported by the hose retainer 53, so that the entire hose car 1 is compact. Therefore, a large number of horse cars 1 can be loaded on the fire engine, and if these many hose cars 1 are used, the fire will be extinguished. Therefore, it is possible to provide a fire extinguishing hose car useful for fire extinguishing activities.

The three turret legs 4 have a simple structure in which the fire extinguishing hose 7 can be stored when they are closed to each other and can be locked to the ground surface when they are opened. In addition, the fire extinguishing nozzle 8 and the base 2 can be stably fixed, so that the fire extinguishing activity can be performed smoothly.

Further, the fire extinguishing nozzle 8 can be freely adjusted in its mounting angle, and can appropriately discharge water or the like to a place where a fire occurs, so that fire extinguishing can be promoted.

Further, an experiment was conducted using the fire extinguisher hose car of the present embodiment and a case using the conventional fire extinguishing method, and the operation time until the fire extinguishing preparation was completed was examined. Table 1 shows the comparison results. At this time, supply water to the fire engine from the fire hydrant along the road of the petroleum complex, extend the fire hose from the fire engine to the expected fire location, and operate until water discharge or foam emission becomes possible. Yes, the distance from the fire truck to the fire location was 80 meters. In addition, three fire hoses, each 20 meters long, were used. In addition, the worker who performed the experiment was a person who has the average physical strength of the age, and performed the operation until the completion of the fire extinguishing preparation by each method under the same conditions.

[0048]

[Table 1]

As shown in Table 1, when the fire extinguisher hose car of this embodiment was used, the operation time was 1/3 to 1/4 of that of the conventional system in each age, and the fire extinguishing preparation was completed. It can be seen that there is a large difference in the present embodiment that the degree of fatigue is almost negligible, as compared with the conventional methods having large or very large degrees. Thus, in the fire extinguisher hose car of the present embodiment, the fire extinguishing preparation can be performed in a short time,
This has the effect of speeding up the initial fire fighting activity.

The present invention is not limited to the above-described embodiment, but includes the following modifications. That is, in the above-described embodiment, when the rear leg 41 is connected and fixed to the front leg 40, the leg connecting rod 54 is engaged with the engaging hole at the upper end of the rear leg 41. The rear legs 41 and the like can be freely opened and closed.

Further, in the above embodiment, the wheels 3 are
Although the tubeless type is used, any type of wheel may be used. In short, the fire extinguisher car can be moved.

Further, in the above embodiment, the fire hose car for fire extinguishing is loaded on the fire engine and the hose is extended and used at the site of the fire occurrence. However, the present invention is not limited to this. It may be installed and used at all times. By doing so, the fire extinguishing work can be performed on the fire in the range in which the hose of the hose car extends, before the fire engine is dispatched, so that there is an effect that the initial fire extinguishing activity becomes possible.

In addition, the specific structure, shape, and the like when implementing the present invention may be other structures as long as the object of the present invention can be achieved.
