Description

The present invention relates to a fire extinguishing tire and a system for extinguishing a fire generated in a construction work place.

For example, when a fire breaks out in a narrow space of a construction work place such as a tunnel, the fire is likely to spread over a wide area because the inside of the tunnel is forcibly ventilated or natural ventilation occurs. Therefore, in order to prevent the spread of the fire, it is important to carry out prompt fire extinguishing activities after the fire breaks out.

On the other hand, conventional fire extinguishing systems that install sprinklers and the like to detect fires and release water and powder fire extinguishing agents so that fires can be extinguished at an early stage have been used in all fields (for example, patent documents). 1. See Patent Document 2).

It is a feature.

Further, the fire extinguishing tire of the present invention is provided with an inner tube in which a high-pressure gas is sealed in a pressurized state inside the tire outer shell, and a fire extinguishing agent is sealed in the space between the inner tube and the tire outer shell. The inner tube is provided on the inner side in the axial direction, and the fire extinguishing agent is sealed between the inner tube on the outer side in the axial direction of the inner tube and the outer shell of the tire.

Further, the fire extinguishing tire of the present invention is provided with an inner tube in which a high-pressure gas is sealed in a pressurized state inside the tire outer shell, and a fire extinguishing agent is sealed in the space between the inner tube and the tire outer shell. It is characterized in that a plurality of inner tubes are provided at intervals in the circumferential direction of the center of the axis, and the fire extinguishing agent is sealed between the inner tubes adjacent to each other in the circumferential direction.

The fire extinguishing system of the construction work place of the present invention is characterized in that any of the above-mentioned fire extinguishing tires is used as the tire of the construction work vehicle.

In the fire extinguishing tire of the present invention and the fire extinguishing system of a construction work place, a fire extinguishing agent can be ejected from the tire when a fire occurs. This enables quick fire extinguishing activities even at construction sites where it is difficult to install fire extinguishing equipment such as sprinklers.

It is a figure which shows the fire extinguishing tire which concerns on one Embodiment of this invention. It is a figure which shows the modification example of the fire extinguishing tire which concerns on one Embodiment of this invention. It is a figure which shows the modification example of the fire extinguishing tire which concerns on one Embodiment of this invention.

Hereinafter, a fire extinguishing tire and a fire extinguishing system in a construction work place according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In the fire extinguishing system of the construction work place of the present embodiment, as shown in FIG. 1, a fire extinguishing agent 2 such as fire extinguishing water is put in the tire 1 of a large tire-driven heavy machine (construction work machine) such as a dump truck. In normal times, the heavy machinery is operated in this state, and in the event of a fire, the fire extinguishing agent 2 is sprayed from the tire 1 to extinguish the fire.

Here, at the construction site, it is conceivable that an accident caused by heavy machinery may occur, and at the construction site of a tunnel where heavy machinery is frequently used, it is conceivable that a fire may occur due to a collision accident between heavy machinery near the face, for example. .. In the event of a fire caused by a heavy machine containing the fire extinguishing agent 2 in the tire 1 causing an accident, the fire extinguishing agent 2 in the tire 1 is released when the tire 1 burns and bursts. , Can also be responsible for extinguishing the fire.

More specifically, for example, in the fire extinguishing tire 1 of the present embodiment, as shown in FIG. 1, an inner tube 4 in which a high-pressure gas 3 is sealed in a pressurized state is formed inside the tire outer shell (forming the outer shell of the tire 1). The tire rubber) 5 is arranged in a substantially concentric circle, and a fire extinguishing agent 2 such as fire extinguishing water is sealed between the inner tube 4 and the tire outer shell 5. Further, a discharge nozzle for the fire extinguishing agent 2 is attached to a predetermined position on the tire outer shell 5.

In the fire extinguishing tire 1 of the present embodiment configured in this way, since the discharge nozzle is normally closed and the fire extinguishing agent 2 and the high pressure gas 3 are sealed, the original function of the tire is maintained and the tire is mounted. It is possible to operate heavy machinery and the like as usual.

On the other hand, in the event of a fire, when an operator such as a driver opens the discharge nozzle, the fire extinguishing agent 2 sealed between the tire outer shell 5 and the inner tube 4 is ejected from the discharge nozzle to the outside. do. Further, at this time, since the high pressure gas 3 is enclosed in the inner tube 4, the fire extinguishing agent 2 is ejected outward from the discharge nozzle and the inner tube 4 expands, so that the fire extinguishing agent 2 is ejected from the discharge nozzle with a desired pressure. Can be made to. Further, since the area in which the fire extinguishing agent 2 is enclosed is filled with the inner tube 4, the contact pressure of the tire 1 can be suitably secured during and after the fire extinguishing agent 2 is ejected, and the running is not hindered.

As a result, when a fire breaks out, the fire extinguishing agent 2 is ejected from the tire 1 in the desired direction at the stage where the vehicle such as a heavy machine is driven while the fire extinguishing agent 2 is ejected from the tire 1 or the vehicle is stopped at a desired position. It will be possible to extinguish the fire by letting it spout out.

Further, even if a vehicle equipped with the fire extinguishing tire 1 causes an accident and the fire extinguishing tire 1 burns or is damaged, the fire extinguishing agent 2 is released from the damaged portion of the tire 1 while the inner tube 4 expands. To. Therefore, it is possible to effectively stop the occurrence and spread (spreading of fire) of a fire in the event of a vehicle accident.

The configuration of the fire extinguishing tire 1 of the present embodiment is not necessarily limited as described above.

For example, an inner tube 4 containing a high-pressure gas 3 is provided on the axle side of the inner space of the tire 1 (inside the tire outer shell 5), and a fire extinguishing agent is provided on the outside of the vehicle (on the tire exposed side) than the inner tube 4 of the inner air of the tire 1. 2 may be enclosed, and the fire extinguishing agent 2 may be ejected from the side surface side of the tire 1 toward the side outside of the vehicle while expanding the inner tube 4 to the outside of the vehicle in the event of a fire.

Further, a plurality of inner tubes 4 are provided at intervals in the circumferential direction in the tire outer shell 5 in the circumferential direction, and a fire extinguishing agent 2 is sealed between the inner tubes 4 adjacent to each other in the circumferential direction. The inner tube 4 may be inflated and the fire extinguishing agent 2 may be ejected.

Even with such a configuration, the same action and effect as the above-mentioned fire extinguishing tire 1 can be obtained.

Therefore, according to the fire extinguishing tire 1 of the present embodiment and the fire extinguishing system of the construction work place, rapid fire extinguishing activities can be performed even at a construction site where it is difficult to install fire extinguishing equipment such as a sprinkler.

Although one embodiment of the fire extinguishing tire and the fire extinguishing system of the construction work place according to the present invention has been described above, the present invention is not limited to the above one embodiment and can be appropriately changed without departing from the spirit thereof. Is.
