TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a fire engine equipped with a basket on which a water discharge gun is disposed at a tip of a telescopic ladder (boom).
[0002]
[Prior art]
When a fire truck with a basket attached to the end of a telescopic ladder (boom) is dispatched to fight fire, when the fire site is on a high floor, workers are put on the basket to extend the ladder, and this basket is attached to the building. Workers on the basket approached the fire site and operated the water gun mounted on the basket to extinguish the fire. In addition, when it is not possible to get close to the fire spot by riding a basket, an operator who operates a telescopic ladder (boom) at the operation unit of the body of the fire engine operates a water discharge gun to perform a fire extinguishing operation.
[0003]
[Problems to be solved by the invention]
When the fire site is on multiple high-rise floors, rely on the experience and intuition of workers and operators in the basket attached to the tip of the ladder (boom) to operate the water spray gun from the first accessible floor. Fire extinguishing work has been carried out, and fire extinguishing work has been performed on another floor when the fire has been extinguished to some extent. In such a case, the fire spreads on the floor where the fire extinguishing operation is postponed, resulting in greater damage. Therefore, in the fire extinguishing work on the postponed floor, it is necessary to perform water discharge aiming at the fire point accurately, but from the floor where the first water was discharged the work to direct the water discharge direction of the water spray gun to the fire point on another floor In such a case, the basket may not be able to be moved to rescue people, and it is difficult to identify the fire point on another floor from within the basket, making it difficult to determine the direction of water discharge. This is very difficult, and the burden on workers and operators is greatly improved.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a fire engine that reduces the burden on workers and operators involved in changing the direction of water discharge of a water spray gun when extinguishing fire on a plurality of high-rise floors.
[0005]
[Means for Solving the Problems]
The invention according to claim 1 is a fire engine in which a basket in which a water spray gun is arranged is attached to a tip of a telescopic ladder, and the water gun is raised and lowered together with the basket by expansion and contraction of the ladder, and the fire truck is moved up and down along the telescopic ladder. A fire extinguisher equipped with a fire extinguishing device attached to a lifter, wherein the fire extinguishing device can perform a fire extinguishing operation by discharging water from the lifter or releasing a fire extinguishing liquid or a fire extinguishing gas separately from the fire extinguishing operation by discharging water from a basket. is there.
[0006]
According to the fire-fighting vehicle according to claim 1, in firefighting work on a plurality of high-rise floors, when a worker in a basket operates a water discharge gun from the floor to which the worker can first approach and discharges water from the lifter. The worker can move the lifter freely and check the fire point on another floor while discharging water from the lifter by the fire extinguishing equipment, thereby reducing the burden on the workers and operators in the basket.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view of a fire engine according to a first embodiment of the present invention, FIG. 2 is a plan view of the lifter of FIG. 1, FIG. 3 is a side view of FIG. 2, and FIG. 4 is a second embodiment of the present invention. FIG. 5 is a schematic view for explaining a use state of the fire engine according to the present invention.
[0008]
1 to 3, a fire ladder truck 1 includes a swivel 3 attached to a vehicle body 2 so as to be rotatable around a vertical axis, and a support 5 attached to the swivel 3 so as to swing about a horizontal axis 4. And an extendable ladder 6 attached to the support base 5. A basket (moving body for high-altitude work) 7 attached to the tip of the ladder 6 allows a worker to get in during high-altitude work. A water spray gun 8 is attached to the side of the basket 7 so as to discharge water mainly in the front direction of the basket 7, and operates the remote control device 11 of the operation cabinet 9 provided on the front of the basket 7 when working at a high place. Thus, the operation of the water discharge gun 8 is enabled. The remote control device 11 provided in the operation cabinet 9 can be removed, and can be freely removed and carried. The vehicle body 2 is provided with an operation unit 19 having a seat S, so that an operator can sit on the seat and operate the ladder 6 or the water discharge gun 8 to extinguish the fire.
[0009]
A lifter 10 is attached to the ladder 6 and moves up and down along the ladder 6. A water gun 12 is attached to the side of the lifter 10 so as to discharge water in the direction of the side of the ladder 6. Water can be discharged from the lifter 10 by the water gun 12 separately from the water discharge from the basket 7 by the water gun 8. Has become. That is, the worker who got on the lifter 10 sets the water discharge direction of the water discharge gun 12 with the operation lever 14 provided on the lifter 10, and operates the water discharge gun 12 by performing the water discharge start operation and the water discharge stop operation of the operation knob 15. Has become possible. The water discharge gun 8 is connected to an extendable hose (not shown) together with the ladder 6, and receives water from the vehicle 2 for fire fighting water discharge. The hose 13 is attached to the water discharge gun 12 by opening the opening / closing door 16 provided at the bottom of the lifter 10 and connecting the hose 13 drawn into the lifter 10 to the mounting portion 17 of the water discharge gun 12. The hose 13 is extendable and retractable together with the ladder 6, and the water gun 12 receives water from the vehicle body 2 and discharges water, similarly to the water gun 8.
[0010]
If the firefighting water replenishing power from the vehicle body 2 is weak, the water discharge from the lifter 10 may weaken the water discharge from the basket 7. In such a case, as shown in FIG. 4, a small fire extinguishing system 20 is connected to the water discharge gun 12, and the water discharge gun 12 discharges a fire extinguishing liquid, a fire extinguishing gas, or a fire extinguishing liquid in which a fire extinguishing agent is foamed. You may do so. If the fire extinguishing equipment 20 has a structure provided with a fire extinguishing nozzle for discharging a fire extinguishing liquid or a fire extinguishing gas, the fire extinguishing gun 12 does not need to be used. Workers may carry and use the fire extinguishing work on the floor.
[0011]
Further, it is also possible to discharge water while the lifter 10 is unattended. In this case, the operator operating the telescopic ladder (boom) 6 at the operation unit 19 of the body 2 of the fire engine can be operated by the operator at the fire site on the upper floor. Can be grasped to some extent, the operator can control the water gun 12 by operating the remote control device in the operation unit 19 to control the water gun 12 up, down, left, and right by aiming at the fire point. .
[0012]
【The invention's effect】
As described above, according to the present invention, in fire extinguishing work on a plurality of high-rise floors, when a worker in a basket operates a water discharge gun from the first accessible floor to discharge water, Can move the lifter freely and discharge water from the lifter by the fire extinguishing equipment while checking the fire point of another floor, so that the burden on the workers and operators in the basket is reduced.
[0013]
Therefore, in firefighting work with one fire engine on a plurality of high-rise floors, a plurality of water discharge guns can be operated independently to perform firefighting work on a plurality of floors. It is also less likely that the fire will be delayed and fire extinguishing work will be postponed, which will prevent the spread of fires and increase the damage, and also direct the water discharge direction of the water spray gun to the fire point on another floor Is reduced, the burden on workers and operators is reduced, and fire extinguishing activities can be advanced efficiently.
