According to this embodiment, the swaying of the hose car while the fire engine is traveling can be suppressed by the swaying suppressing member. [Example]

[0022] A fire engine according to an embodiment of the present invention will now be described. Figures 1 to 3 show a fire engine, with Figure 1(a) being a right side view, Figure 1(b) being a left side view, Figure 2(a) being a top view showing the suction tube storage compartment, Figure 2(b) being a top view showing the water pump, and Figure 3 being a rear view. The fire engine 1 comprises a cabin 2 located at the front of the vehicle and a loading platform 3 located behind the cabin 2. On the loading platform 3 are mounted an equipment storage shed 4, a water pump 5, a control panel 6 used to operate the water pump 5, a water tank 7 for storing water for firefighting to be supplied to the water pump 5, a suction pipe storage shed 8, a ladder storage device 9, a hose car 10 used to transport discharge pipes (fire hoses), and a hose car storage shed 11. The base vehicle for the fire engine 1 is, for example, a BEV (Battery Electric Vehicle). The cabin 2 consists of a front cabin 2A with a driver's seat and a passenger seat, and a rear cabin 2B with a rear seat. An opening is formed in the wall separating the front cabin 2A and the rear cabin 2B, allowing the firefighters in the front cabin 2A and the firefighters in the rear cabin 2B to talk face-to-face. The loading platform 3 is provided on the chassis frame behind the cabin 2. The floor of the loading platform 3 is flat, and vertically sliding shutters 12 are provided on the left and right sides. Note that Figures 1 and 2 show the shutters 12 in the raised position. The loading platform 3 may also be provided on a subframe rather than the chassis frame. In this case, the subframe is installed on the chassis frame, and the loading platform 3 is installed on the subframe. The water pump 5, the water tank 7, and the suction pipe storage 8 are arranged at a rear part of the vehicle at a distance from the cabin 2.

[0023] The equipment storage shed 4 is located immediately behind the cabin 2 and is equipped with shelves, brackets, etc. for storing equipment used in firefighting activities. The floor of the equipment storage shed 4 is the same as that of the loading platform 3, and its height from the ground is low, making it easier for firefighters to climb into the equipment storage shed 4. In addition, on both sides of the equipment storage shed 4, there are retractable steps 13 that firefighters can use to climb up and down onto the loading platform 3. In addition, the equipment storage shed 4 is designed to reach the roof surface of the loading platform 3, has a flat floor, and is fully open on the left and right sides, penetrating from the floor to the ceiling in the left-right direction of the vehicle, thereby increasing the storage capacity and increasing the freedom in the configuration and arrangement of shelves, brackets, etc. for storing equipment and materials.

[0024] The water pump 5 is driven by a motor 15 powered by a battery 14 to discharge pressurized water. The pressurized water coming out of the water pump 5 is sprayed toward a fire or the like from a nozzle attached to the tip of the discharge pipe. In this embodiment, the battery 14 is installed below the floor surface of the loading platform 3. By installing the battery 14 below the floor, the freed up space above the floor can be used as a space for placing equipment and materials.

[0025] The control panel 6 is equipped with a monitor 6A that displays various information such as flow rate, a pressure gauge 6B, a compound gauge 6C, an operation switch 6D, a speaker, etc., and is used by firefighters to monitor the status and operate the water pump 5. The height from the ground of the control panel 6, particularly the monitor 6A, pressure gauge 6B, compound gauge 6C, and operation switch 6D, is preferably 1700 mm or less, so that even people who are not very tall can easily see and operate them.

[0026] The height of the suction pipe storage 8 is set smaller than the width and length, and the suction pipe 16 is stored wound horizontally rather than vertically. The suction pipe 16 is used to supply water to the water pump 5 by connecting its tip to a water source such as a reservoir or fire-fighting water tank. The suction pipe storage 8 has three suction pipe entrances 8A through which the suction pipes 16 are pulled out: one on the rear side of the vehicle and one on each side of the vehicle, so that firefighters can select the suction pipe entrance 8A that is easiest to use depending on the surrounding conditions, the location of the water source, etc.

[0027] The suction pipe storage 8 and the water pump 5 are arranged one above the other at the rear of the vehicle, and the suction pipe entrance / exit 8A, the control panel 6, the water outlet 17, and the relay port 18 are provided on the rear of the vehicle. By concentrating the suction pipe entrance / exit 8A, the control panel 6, the water outlet 17, and the relay outlet 18 at the rear of the fire engine 1, firefighters can deploy the suction pipe 16 and the water outlet, and operate the water pump 5, etc., at the rear of the vehicle, making it possible to start firefighting early even in areas with narrow roads where it is difficult to secure working space to the side of the vehicle.

[0028] The hose car storage shed 11 is located at the rear right of the vehicle, and a hose car entrance / exit 11A, which is an entrance / exit for the hose car 10 in the hose car storage shed 11, is provided on the rear right side of the vehicle. By making it possible to take the hose car 10 in and out from the rear of the vehicle in this way, convenience for firefighters can be further improved. Here, in order to ensure space for arranging the hose car storage shed 11 at the right rear of the vehicle and to locate the hose car entrance 11A at the rear of the vehicle, the water pump 5 is entirely located to the left of the center in the vehicle width direction, and more than 60% of the suction pipe entrance 8A is located to the left of the center in the vehicle width direction, so the water pump 5 and the suction pipe entrance 8A at the rear of the vehicle are located close to the left side of the vehicle. Also, the width of the suction pipe entrance 8A at the rear of the vehicle is made smaller than the width of the suction pipe entrance 8A on the side of the vehicle, and the suction pipe entrance 8A on the right side of the vehicle is located forward of the hose car storage shed 11.

[0029] The ladder storage device 9 is used to store portable ladders and is installed on the roof of the loading platform 3. The ladder storage device 9 is configured so that the platform that holds the ladder can be pulled out diagonally downwards, allowing the ladder to be taken out and stored while close to the ground. The platform is also pulled out towards the rear of the vehicle, which means that the ladder can be taken out from the rear of the vehicle.

[0030] The ladder storage device 9 and hose car entrance 11A are located on the right side of the vehicle, while the suction pipe entrance 8A, water discharge port 17, and relay port 18 at the rear of the vehicle are located on the left side of the vehicle. By dividing the area into left and right in this way, it is possible to perform operations such as removing the hose car 10 and ladder even when the suction pipe 16 and water discharge pipe are deployed. It is also possible to place the ladder storage device 9 and the hose car storage shed 11 on the left side of the vehicle, and the suction pipe entrance / exit 8A, the water outlet 17, and the relay port 18 on the rear of the vehicle on the right side of the vehicle.

[0031] At the rear of the vehicle, a suction pipe storage 8 is placed on the floor, a water pump 5 is placed on top of that, and a water tank 7 is placed on top of that. By arranging the suction pipe storage 8, water pump 5, and water tank 7 one on top of the other in this way, a large space can be secured for the equipment storage 4 located on the front side of the loading platform 3, making it possible to load a large amount of equipment. Furthermore, as described above, the height dimension of the suction pipe storage 8 is reduced by storing the suction pipe 16 in a horizontally wound state, so that even if the water pump 5 and the water tank 7 are arranged in the suction pipe storage 8 in a stacked manner, the vehicle height can be kept within the specified range. The suction tube storage 8 can be disposed above the water pump 5, but is preferably disposed below the water pump 5 as in this embodiment. This makes it easier to set the height of the suction tube entrance 8A from the ground low so as to facilitate the deployment and storage of the suction tube 16. Furthermore, although the water pump 5 can be placed above the water tank 7, it is preferable to place it below the water tank 7 as in this embodiment. This makes it easier to set the height of the water outlet 17 and relay port 18 from the ground low to facilitate the connection and disconnection of the water discharge pipe, etc. It is preferable that the height of the water outlet 17 and relay port 18 from the ground be 1300 mm or less.

[0032] Fig. 4 shows the suction tube storage case, Fig. 4(a) is a top view, Fig. 4(b) is a right side view, and Fig. 4(c) is a rear view. Fig. 5 is a perspective view showing the winding device in a non-rotatable state. A manual reeling device 19 for reeling in the suction pipe 16 is installed in the suction pipe storage 8 so as to be horizontally rotatable, and the rear end of the suction pipe 16 is connected to the water suction pipe near the rotation center of the reeling device 19. By installing the reeling device 19, firefighters can deploy and reel in the suction pipe 16 more smoothly. The suction pipe entrance 8A has no door or the like and is always open, so that firefighters can immediately remove the suction pipe 16 after arriving at the scene. When stored, the suction pipe 16 is held in a wound state by the winding device 19, so even though there is no door or the like at the suction pipe entrance 8A, the suction pipe 16 will not fly out while the fire engine 1 is traveling.

[0033] The suction tube opening 8A is rectangular, and rod-shaped rollers are arranged on the inner periphery thereof, which rotate when they come into contact with the suction tube 16. The rollers include horizontal rollers 20A, which have a horizontal rotation axis and are arranged above and below the suction tube opening 8A, and vertical rollers 20B, which have a vertical rotation axis and are arranged on the left and right sides of the suction tube opening 8A. By providing the rollers 20A, 20B to reduce the frictional resistance of the suction tube 16 at the suction tube entrance 8A, the suction tube 16 is prevented from getting caught in the suction tube entrance 8A when being wound up or unwound, and the operation of inserting and removing the suction tube 16 can be carried out smoothly. In addition, rollers 20A and 20B are provided as appropriate on the way from the winding device 19 to the suction tube entrance 8A so that the suction tube 16 can be inserted and removed more smoothly.

[0034] The winding device 19 has a circular lock plate 21 fitted onto a rotating shaft, a ring 22 located at the outer end, and a plurality of spokes 23 connecting the lock plate 21 and the ring 22, which rotate together. If the retracting device 19 were always free to rotate, there is a possibility that it would rotate on its own while the fire engine 1 is moving, so that firefighters can place the retracting device 19 in a non-rotating state as needed by providing a rotation stopper 24 inside the suction tube storage case 8, which prevents rotation by contacting the lock plate 21, and providing a rotation stopper operating device 25 outside the suction tube storage case 8 for use in operating the rotation stopper 24. It is also possible to have the rotation stopper 24 prevent rotation by contacting the ring 22 or spokes 23 instead of the lock plate 21. When the rotation stop operating device 25 is operated, the rotation stop member 24 is configured to be displaced to either a non-contact position that is off the rotation trajectory of the lock plate 21, or a contact position that is on the rotation trajectory of the lock plate 21. By operating the rotation stop operating device 25, the firefighters can move the rotation stop member 24 to the non-contact position when the winding device 19 is to be allowed to rotate, or to the contact position when the winding device 19 is to be prevented from rotating.

[0035] In this embodiment, a plurality of recesses 21A are formed at predetermined intervals on the outer edge of a circular lock plate 21 located on the inner ring side, and a rotation stop member 24 (solenoid latch, etc.) equipped with a solenoid actuator is placed in one location above the recesses 21A, so that the pin-shaped rotation stop member 24 (latch) moves upward or downward when current is applied to the solenoid actuator. When a firefighter operates rotation stop operating device 25 and causes rotation stop member 24 to project downward and be inserted into recess 21A as shown in Figure 5, lock plate 21 is obstructed by rotation stop member 24 and becomes almost immobile, preventing reel device 19 from rotating. On the other hand, when an operation to move rotation stop member 24 upward is performed using rotation stop operating device 25, rotation stop member 24 retracts upward and comes out of recess 21A, allowing lock plate 21 to move freely and allowing reel device 19 to rotate.

[0036] When a plurality of suction tube entrances 8A are provided in the suction tube storage 8, it is preferable to provide a rotation stop operating device 25 for each suction tube entrance 8A as in this embodiment. This allows firefighters to lock or unlock the retractor 19 with the rotation stop member 24 from the vicinity of any of the suction tube entrances 8A, thereby eliminating the need to change locations just to operate the rotation stop operating device 25 and improving convenience. It is also preferable to provide a reel-up device indicator lamp near the rotation stop operating device 25 that indicates whether the rotation stop member 24 is in the non-contact position or the contact position. This allows firefighters to know at a glance whether the reel-up device 19 is in a rotatable state or a non-rotatable state. For example, the reel-up device indicator lamp is lit when the rotation stop member 24 is in the non-contact position and is off when it is in the contact position.

[0037] As described above, the retracting device 19 is free to rotate when the suction pipe 16 is extended or retracted, and rotates naturally in accordance with the movement of the suction pipe 16, so that a firefighter can extend or retract the suction pipe 16 by himself. However, in order to reduce the burden on firefighters and to speed up the work, it is preferable that the work be performed by two or more people rather than one person. When two or more people are working together, for example, one person may hold and move the suction pipe 16 while another person manually assists in the rotation of the reel device 19. However, if these work are done at the same suction pipe inlet / outlet 8A, there is a possibility that they may interfere with each other's work. Therefore, by providing the suction pipe inlet / outlet 8A at the rear and side of the vehicle as in this embodiment, for example, when pulling out the suction pipe 16 rearward, one person may hold the suction pipe 16 near the suction pipe inlet / outlet 8A at the rear of the vehicle, and another person may reach into the suction pipe storage 8 through the suction pipe inlet / outlet 8A at the side of the vehicle to assist in the rotation of the reel device 19, thereby enabling two or more firefighters to work together to smoothly take in and out the suction pipe 16.

[0038] Fig. 6 shows the hose car storage shed, Fig. 6(a) is a front view, Fig. 6(b) is a right side view, and Fig. 7 is a perspective view showing the vicinity of the upper end of the lift. The hose car 10 is loaded and unloaded from the hose car storage shed 11 through a hose car entrance / exit 11A located at the rear of the vehicle. The hose car storage shed 11 is provided with a door 26 (see FIG. 3) located at the hose car entrance / exit 11A, a lift 27 on which the hose car 10 is placed, an elevator 28 that raises and lowers the lift 27 between an upper storage position and a lower removal position, a controller 29 that controls the elevator 28, an elevator operating device 30 used to operate the elevator 28, a support device 31 that supports the lift 27 in the storage position to prevent it from falling, a swing suppressor 32 that prevents the stored hose car 10 from swinging, an elevation detector such as a limit switch that detects when the lift 27 has risen to a predetermined height, and a hose car indicator lamp that indicates whether the hose car 10 is stored. The hose car indicator lamp is off when the hose car 10 is stored and is on when the hose car 10 is not stored. The elevator 28 in this embodiment is an electric winch, and the controller 29 controls the operation of the elevator 28 to wind up (take up) and wind down (deliver) the wire in response to the operation of the elevator operating device 30 .

[0039] The lift 27 includes a rail 27A fixed vertically to the vehicle body at the rear of the hose car storage shed 11, and a slider 27B that reciprocates on the rail 27A. The slider 27B is configured to be roughly L-shaped in side view, with a horizontal floor 27Ba on which the bottom of the hose car 10 rests, and a wall 27Bb that has casters and is provided parallel to the rail 27A. A rod-shaped wire hook 27Bc, to which the wire of the elevator 28 is connected via a pulley 33, is hung horizontally in the left-right direction from the upper end of the wall 27Bb. In addition, a through-hole 27Bd that penetrates in the front-rear direction is formed immediately below the wire hook 27Bc. The support device 31 includes a plate-shaped claw 31A that can be inserted and removed from the opening, an operating lever 31B connected to the claw 31A and used by firefighters to manually lock and unlock the claw 31A when sliding it back and forth, and a connecting portion 31C that connects the operating lever 31B to the claw 31A. The operating lever 31B can be switched between a locked position, which locks the claw 31A so that it does not slide, and an unlocked position, which does not lock the sliding movement of the claw 31A. A lever position detector such as a proximity switch is provided near the locked position to detect when the operating lever 31B is in the locked position. The hose car indicator lamp is turned off when the lever position detector detects that the operating lever 31B is in the locked position, and is turned on when the lever position detector does not detect that the operating lever 31B is in the locked position, i.e., when the operating lever 31B is not in the locked position.

[0040] An example of the procedure that firefighters follow when storing the hose car 10 in the fire engine 1 is as follows. 1-1. Open the shutter 12 on the side of the luggage compartment and make sure that the operating lever 31B is in the unlocked position. 1-2. Open the door 26, push the hose car 10 into the hose car storage shed 11 so that the tire 10C (see FIG. 8) is at the rear of the vehicle, and place it on the lift 27. 1-3. Press the up button of the lifting / lowering operation device 30. While the up button is pressed, the controller 29 causes the elevator 28 to perform the operation of winding up the wire, and the lift 27 rises as the wire is wound up. When the rise detector detects that the lift 27 has risen to the storage position, the controller 29 causes the elevator 28 to stop the operation of winding up the wire. 1-4. When the winding of the wire automatically stops, stop pressing the up button. Slide the claw 31A toward the rear of the vehicle and insert it into the through-hole 27Bd to insert the claw 31A into the descending trajectory of the lift 27. Then, move the operating lever 31B to the lock position. This prevents the lift 27 from sliding down beyond a certain level, since the support material will catch the wire even if it becomes loose. In this state, the claw 31A is not in contact with the lift 27 or is in light contact with it. Also, the hose car indicator light turns off when the operating lever 31B is moved to the lock position. 1-5. Make sure the hose car indicator light is off and close door 26.

[0041] In steps 1-4 above, when the controller 29 detects that the claw 31A of the lift 27 has ascended to the storage position and entered the descending trajectory, for example, when the lever position detector detects that the operating lever 31B has been moved to the lock position, the controller 29 causes the elevator 28 to perform an operation to lower the wire by about several millimeters. This lowering operation ends, for example, when a set time (e.g., about 1 to 2 seconds) has elapsed since the start of the lowering. This causes the lift 27 to descend slightly, making deep contact with the claw 31A inserted into the penetration portion 27Bd, thereby reducing the load on the wire. Therefore, the hose car 10 can be stored with the tension on the wire of the elevator 28 relaxed.

[0042] On the other hand, an example of the procedure when a firefighter removes the hose car 10 from the fire engine 1 is as follows. 2-1. Open the shutter 12 on the side of the luggage compartment and move the operating lever 31B to the unlock position. When the operating lever 31B is in the unlock position, the hose car indicator lamp lights up. 2-2. In order to remove the claw portion 31A from the descending trajectory of the lift 27, the claw portion 31A is slid toward the front side of the vehicle until it comes out of the through-hole 27Bd. 2-3. Open the door 26 and press the down button on the elevator operating device 30. While the down button is being pressed, the controller 29 causes the elevator 28 to wind down the wire, and the lift 27 descends as the wire is wound down. When the tire 10C of the hose car 10 lands, the pressing of the down button is stopped. 2-4. Pull out the hose car 10.

[0043] In step 2-1 above, when the controller 29 detects that the claw 31A has left the descent trajectory, for example, by detecting that the operating lever 31B has been moved from the locked position using a lever position detector, the controller 29 causes the elevator 28 to reel in the wire by a few millimeters to remove slack. This reeling operation ends, for example, when a set time (e.g., about 1 to 2 seconds) has elapsed since the start of the reeling. As a result, the lift 27 is suspended by the wire and rises slightly, eliminating the deep contact with the claw 31A inserted into the through-hole 27Bd. This makes it easier to pull the claw 31A out of the through-hole 27Bd. Furthermore, by keeping the lift 27 suspended by the wire, it is possible to prevent the lift 27 from suddenly sliding down when the claw 31A is pulled out.

[0044] The sway suppressing members 32 are provided at two locations on the outside, left and right, of rails 27A attached to the back side of the hose car storage shed 11, at positions slightly higher than the floor 27Ba of the lift 27 when in the storage position, and when the lift 27 rises to the storage position and automatically stops, an engagement pin 10E (see FIG. 8) provided on the bottom of the hose car 10 engages from below with the sway suppressing members 32. This allows the swaying of the hose car 10 to be suppressed by the sway suppressing members 32, preventing the hose car 10 from jumping around while the fire engine 1 is traveling, for example.

[0045] FIG. 8 shows a hose car, where FIG. 8(a) is a side view, FIG. 8(b) is a top view, and FIG. 8(c) shows a firefighter pulling the hose car. The hose car 10 loaded on the fire engine 1 has a basket- or box-shaped main body 10A, a handle 10B attached to the top of the main body 10A that the firefighters grip when moving the hose car 10, a pair of left and right tires 10C, a stand 10D that holds the hose car 10 upright, and engaging pins 10E that protrude from the left and right sides of the bottom of the main body 10A and engage with the sway suppression members 32 when stored. Also, to increase the number of hoses that can be loaded, a hose fall prevention frame 10F is provided around the periphery of the top surface of the main body 10A, allowing hoses to be loaded on top of the main body 10A as well. The main body 10A has a vertically elongated shape with a height greater than its width and length. This minimizes the required longitudinal dimensions of the hose car storage shed 11 and shortens the distance from the rear wheels of the fire engine 1 to the rear end of the bed 3 (rear overhang).

[0046] The hose car 10 is primarily designed to be pulled, and if the face of the main body 10A that faces the direction of travel when pulling the hose car 10 (the face facing the direction of travel) is defined as the front, the handle 10B is located at the top of the front side, and the tire 10C is located at the bottom of the front side so that a portion of it protrudes forward. The stand 10D and engagement pin 10E are located at the bottom of the rear side, located on the opposite side. The handle 10B protrudes obliquely upward from the main body 10A so that it can be easily pulled by firefighters, but the amount of protrusion is set to be less than the amount of protrusion of the tire 10C in order to reduce the front-to-rear dimension of the hose car storage shed 11.

[0047] The radius of tire 10C is preferably at least larger than the diameter of the 65A hose so that it can ride over the 65A hose, and more preferably at least twice the diameter of the 65A hose to make it easier to ride over it. In addition, the corners of the main body 10A located at the boundary between the bottom and front surfaces preferably have slopes 10G that gradually increase in height toward the front, as in this embodiment. Note that Fig. 8(C) shows the shape of the main body 10A when the corners are not sloped 10G by dotted lines. When the hose cart 10 is pulled, the main body 10A leans forward. However, by providing the lower front surface of the main body 10A with slopes 10G (chamfered shapes) as in this embodiment, the distance from the ground to the bottom surface can be increased compared to when the slopes 10G are not provided. This reliably prevents the main body 10A from getting caught on a hose that is laid on the ground when the main body 10A is going over the hose, thereby preventing the hose from being damaged or taking too long to get over the hose.
