Description

  The present invention relates to a vehicle, and in particular, a vehicle including a cargo box having a floor portion on which equipment is mounted, a chassis frame that supports the cargo box from below, and a suction pipe connected to a suction side of a pump. About.

  Among various vehicles, for example, so-called fire trucks such as pump cars, aquarium tanks equipped with water tanks, rescue work vehicles equipped with telescopic crane devices, and aerial work vehicles equipped with refracting or telescopic ladders Usually, it is equipped with a packing box (also called “article storage room” or “storage box”) for storing various equipment and a suction pipe connected to the suction side of the pump. Is provided with a floor for mounting various equipment. The cargo box is supported from below by a chassis frame supported by wheels.

  The suction pipe is mainly composed of a connection type formed by connecting a plurality of short tubular bodies, and a long tubular body having flexibility (for example, a hose having a length of several m to several tens m). Are roughly classified into hose types (hereinafter also referred to as “hose-shaped suction pipes”). The connection type suction pipe is superior to the hose suction pipe in terms of load handling because each tubular body is short. However, for example, when fire extinguishing activities must be carried out at locations away from various water sources such as fire hydrants and rivers, the connection type suction pipes must be connected to a large number of tubular bodies. This may take time and cause a fire. Therefore, various fire engines in recent times are often equipped with a hose-shaped suction pipe.

  For example, in Patent Document 1 below, a hose suction pipe is held and stored in a state where the hose suction pipe is wound by fitting the hose suction pipe along an annular groove-like fitting portion opened on the outer surface of the vehicle (packing box). The vehicle to be used is described. In Patent Document 2, a hose storage chamber (storage space) is provided between the two storage chambers by separating the front storage chamber and the rear storage chamber in the front-rear direction. In the hose storage chamber, The fluid piping connected to the suction port of the pump is arranged along the longitudinal direction of the vehicle body, the winding body is rotatably supported by the fluid piping, and the hose suction pipe is wound around the outer circumference of the winding body so that it can be unwound. Listed vehicles.

  The hose suction pipe is generally formed of a highly rigid material while having flexibility in order to prevent the reduction of the cross-sectional area of the flow path during fluid suction (during water intake) as much as possible. . Therefore, when the hose-shaped water absorption pipe is wound, the winding diameter inevitably increases. Therefore, when storing in a state in which the hose suction pipe is wound around the side surface of the vehicle as in Patent Document 1, the ground height at the storage position of the hose suction pipe inevitably increases. In addition, the hose-like suction pipe is often quite heavy. For the above reasons, in the configuration of Patent Document 1, the removal (development) of the hose suction pipe from the fitting portion and the attachment (housing) of the hose suction pipe to the fitting portion are performed safely and quickly by one person. In reality, it is necessary to perform these operations with two or more people. In addition, there is a problem in that an area where the hose suction pipe is stored in the outer surface of the vehicle cannot be used as an attachment part or a storage part for other equipment.

  On the other hand, according to the configuration of Patent Document 2, it is possible to deploy the hose suction tube to the side of the vehicle simply by pulling the tip of the hose suction tube and rotating the winder forward. Since the deployed hose suction pipe can be wound up by rotating it, the deployment and storage of the hose suction pipe can be performed safely and quickly by one person. However, if the article storage chamber is separated into the front storage chamber and the rear storage chamber, the dimensions of the storage chambers in the vehicle front-rear direction are reduced, so that the storage mode of the equipment in the storage chamber is limited. The ease of use becomes worse. In addition, since the winding body is provided, the vehicle becomes complicated and heavy. Furthermore, when it is necessary to stop the vehicle on a narrow road and perform fire extinguishing activities, the suction pipe may not be smoothly deployed due to an obstacle on the side of the vehicle.

  In view of the above circumstances, the problem of the present invention is that the construction and storage of the hose suction pipe can be performed safely and promptly even by one person work with a simple configuration, and there is no restriction on the deployment location of the hose suction pipe. Another object is to provide a vehicle capable of improving the usability of the packing box.

  In order to solve the above problems, in the present invention, a cargo box having a floor portion on which equipment is mounted, a chassis frame that supports the cargo box from the lower side, and a long tubular body having flexibility are formed. In a vehicle equipped with a suction pipe connected to the suction side of the pump, the suction pipe storage for storing the suction pipe so that the suction pipe can be taken in and out through an opening opened rearward of the vehicle between the floor portion of the cargo box and the chassis frame. A space is provided, and the suction pipe is stored in the suction pipe storage space while being held by a rotating body whose one end in the longitudinal direction rotates around a vertical axis at a fixed point, and in which at least a partial region in the longitudinal direction is curved. Provided is a vehicle characterized by the above.

  As described above, the suction pipe formed of a long tubular body having flexibility between the floor portion of the cargo box and the chassis frame (hereinafter simply referred to as “suction pipe” when explaining the configuration of the present invention) Is equivalent to the above-mentioned “hose suction tube”), if the suction tube storage space is provided to store and retract, the ground level at the suction tube storage position should be about the height of the operator's waist or less. In addition, if one end of the suction pipe in the longitudinal direction is held by a rotating body that rotates around a vertical axis at a fixed point, when the suction pipe is taken in and out of the suction pipe storage space (when the suction pipe is deployed and stored) The operation of rotating the suction tube around the vertical axis with one end in the longitudinal direction as a fulcrum or bending the suction tube along the longitudinal direction can be safely and quickly performed by one worker. Therefore, according to the present invention, the winding body wound around the outer periphery so that the suction pipe can be unwound and wound can be omitted, and the vehicle can be simplified, and the suction pipe can be deployed and stored safely and quickly by one person. Can be executed. In addition, since the suction pipe is taken into and out of the suction pipe storage space (the suction pipe is expanded and stored) through an opening that opens to the rear of the vehicle, for example, even when the vehicle is stopped on a narrow road, the vehicle side Regardless of the obstacle, the suction pipe can be smoothly deployed and stored.

  In addition, since the suction pipe storage space is provided between the floor portion of the cargo box and the chassis frame, it is not necessary to separately arrange the cargo box at the front and rear of the vehicle as in Patent Document 2, so It can be equipped with a large-capacity packing box with long dimensions. For this reason, the degree of freedom of the equipment storage mode is improved, and the usability of the packing box is improved. Furthermore, because of the configuration of the present invention, a part of the outer surface of the vehicle is not covered with the suction pipe, so that the entire outer surface of the vehicle (packing box) can be used as an attachment part or a storage part for equipment. It becomes possible.

  In the above configuration, the cross-sectional area of the suction pipe storage space (strictly speaking, the cross-sectional area of the suction pipe storage space in the direction orthogonal to the vehicle front-rear direction) approaches the opening in the vehicle rear side region of the suction pipe storage space ( A cross-sectional area enlarging part that gradually expands (toward the rear side of the vehicle) can be provided. In this way, in particular, it is possible to easily and quickly execute the suction pipe storage operation in the suction pipe storage space. The cross-sectional area enlarging portion can be obtained by gradually increasing the opening size of the suction tube storage space in the height direction of the vehicle as it approaches the opening, and the suction tube storage space in the vehicle width direction. Can be obtained by gradually increasing the size of the opening as it approaches the opening. Of course, the cross-sectional area enlarged portion can also be obtained by gradually increasing the opening size of the suction pipe storage space in both the height direction and the width direction of the vehicle as it approaches the opening.

  The vehicle according to the present invention may further include a frictional force reducing means for reducing a frictional force generated when the suction pipe is taken in and out of the suction pipe storage space. In this way, it is possible to more easily and quickly perform the suction pipe expansion and storage operations. As the frictional force reducing means, for example, a rolling member such as a free roller can be preferably employed.

  The suction tube storage space has a plurality of small storage spaces that are vertically divided by one or a plurality of partition plates, and the plurality of small storage spaces communicate with each other in the vehicle rear side region of the suction tube storage space. be able to. In this way, since the suction pipe can be stored in a plurality of small storage spaces, it is possible to prevent the suction pipes from contacting each other at each part in the longitudinal direction. Therefore, the suction pipe can be expanded and stored more quickly, and wear of the suction pipe can be suppressed.

  In the above configuration, the pump can be mounted on the floor of the packing box. In this case, the rotating member can be a swivel joint connected to a fixed pipe on the suction side of the pump. In this way, after deploying the suction pipe (after being pulled out from the suction pipe storage space), the trouble of connecting one end (base end) in the longitudinal direction of the suction pipe to the suction side of the pump can be omitted. This is advantageous in that the deployment work can be performed quickly.

  In the above configuration, the pump may be a pump having a fire extinguishing agent discharge function. In other words, the present invention has a great feature in that it is possible to expedite the expansion and storage of the suction pipe. Therefore, among various vehicles, the fire truck (particularly required to execute the expansion of the suction pipe) is required. For example, it can be suitably used for pump vehicles, aquarium vehicles equipped with water tanks for drainage, rescue work vehicles equipped with telescopic crane devices, and high-altitude work vehicles equipped with refracting or telescopic ladders. . However, the present invention is formed by a packing box having a floor portion on which equipment is mounted, a chassis frame that supports the packing box from the lower side, and a long tubular body having flexibility, and the suction side of the pump If it is provided with a suction pipe connected to the vehicle, it can also be applied to vehicles other than fire engines (for example, vacuum cars).

  As described above, according to the present invention, the deployment and storage of the hose suction pipe can be performed safely and quickly even by a single operation, and the deployment location of the hose suction pipe is restricted, although it has a simple configuration. Furthermore, it is possible to provide a vehicle capable of improving the usability of the packing box.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show a schematic side view, a schematic plan view, and a schematic rear view of the vehicle 1 according to the first embodiment of the present invention. The vehicle 1 shown in FIGS. 1 to 3 is a water tank vehicle (fire tank with water tank) classified as a so-called fire truck, and a chassis frame 3 supported by wheels 2 and an operation supported from below by the chassis frame 3. A chamber 4 and a packing box 5, a suction pipe 8 connected to a suction side of a pump 7 having a fire extinguishing agent (extinguishing fluid) discharge function, and a water tank 9 capable of storing a fire extinguishing fluid such as water. The cargo box 5 has a floor portion 5a extending in the horizontal direction, and a water tank 9 and a pump 7 are mounted on the vehicle front side region and the vehicle rear side region on the floor portion 5a, respectively. The water tank 9 is connected to the pump 7 through a fluid pipe (not shown), and until the water intake by the suction pipe 8 becomes feasible (until the fire extinguishing activity using the water acquired through the suction pipe 8 becomes feasible. In the meantime, a temporary fire extinguishing operation using water stored in the water tank 9 can be performed.

  Although illustration is omitted, the cargo box 5 has openings opened to the side (side surface) and rear (rear surface) of the vehicle 1, and the openings of these cargo boxes 5 are not shown respectively. Closed by the door. As this open / close door, for example, an electric or manual shutter, or a flip-up type open / close door is appropriately employed. Since the pump 7 as equipment is mounted on the rear side region of the floor portion 5a of the cargo box 5, the pump 7 appears when the open / close door that closes the rear opening of the cargo box 5 is opened.

  The suction tube 8 is formed of a long and flexible tube, and a tube having a rigidity sufficient to prevent a reduction in the cross-sectional area of the flow path during fluid suction is selected and used. One end of the suction tube 8 in the longitudinal direction (hereinafter referred to as “base end”) 8a is held (connected) by a rotating body that rotates around a vertical axis at a fixed point, and the other end in the longitudinal direction of the suction tube 8 (hereinafter referred to as “tip”). A water intake is provided at 8b. In the present embodiment, the rotating body is configured by a swivel joint 6 that is disposed on the side of the rear end of the vehicle 1 (on the left side of the rear end in the present embodiment) and connected to the fixed pipe 7a on the suction side of the pump 7. Is done. Therefore, the proximal end 8 a of the suction pipe 8 is connected to the fixed pipe 7 a on the suction side of the pump 7 via the swivel joint 6.

  The suction pipe 8 is stored in a suction pipe storage space 10 provided between the floor portion 5 a of the cargo box 5 and the chassis frame 3. More specifically, the suction pipe 8 is stored in the suction pipe storage space 10 with a base end 8a held by a swivel joint 6 as a rotating body and with at least a partial region in the longitudinal direction curved. The suction tube storage space 10 can be taken in and out through an opening 11 opened to the rear (rear surface) of the vehicle 1.

  The suction pipe storage spaces 10 of the present embodiment are disposed on both sides in the width direction of the vehicle 1 and are fixed to the pair of left and right side plates 12a and 12b extending in the vehicle front-rear direction and the upper and lower ends of the side plates 12a and 12b, respectively. The board 12c and the bottom board 12d are fixed to the front ends of the side plates 12a and 12b, and are formed by an inner space of the housing 12 formed by a front plate 12e extending in the vehicle width direction. 13 is attached and fixed to the chassis frame 3 and the packing box 5 through the door 13. In addition, as the housing | casing 12, you may use what was formed by combining the angle steel which exhibits a cross-sectional L shape, the channel steel which exhibits a cross-sectional concave shape, etc. (illustration omitted). In short, the casing 12 can be used without any problem as long as it can define the suction pipe storage space 10 in which the suction pipe 8 can be inserted and removed. It is. The same applies to other embodiments described later.

  In the vehicle rear side region of the suction pipe storage space 10, a cross-sectional area enlargement portion 14 is provided in which the cross-sectional area of the suction pipe storage space 10 in the direction orthogonal to the front-rear direction of the vehicle 1 is gradually enlarged as the opening 11 is approached. ing. In the present embodiment, the above-described cross-sectional area enlarged portion is provided in the vehicle rear region of the bottom plate 12d by providing the inclined portion 12d1 that is inclined so that the front side is positioned relatively upward and the rear side is positioned relatively downward. 14 is formed. In the present embodiment, the dimension in the vehicle width direction (opening dimension in the vehicle width direction) of the suction pipe storage space 10 is constant over the entire area in the vehicle front-rear direction (see FIG. 2). The vertical dimension (opening dimension in the height direction) is constant over the entire area in the vehicle front-rear direction except for the region where the cross-sectional area enlarged portion 14 is provided (see FIG. 1). With such a configuration, when the vehicle 1 is viewed in plan, the suction tube storage space 10 has a rectangular outline with the longitudinal direction and the width direction of the vehicle 1 as a longitudinal direction and a transverse direction, respectively (see FIG. 2).

  Although there is no restriction | limiting in particular in the accommodation aspect of the suction pipe 8 with respect to the suction pipe storage space 10, In this embodiment, when the suction pipe storage space 10 is planarly viewed (refer FIG. 2), it goes around along the four sides which define the suction pipe storage space 10 In this manner, the suction pipe 8 is stored in the suction pipe storage space 10. Although not shown in the drawings, the vehicle 1 prevents as much as possible that a part or all of the suction pipe 8 stored in the suction pipe storage space 10 is expanded outside when the vehicle 1 is driven. Deployment prevention means is provided. As the expansion preventing means, for example, it is conceivable to provide a fixing bracket for gripping a part of the suction pipe and an opening / closing door capable of closing part or all of the opening 11 of the suction pipe storage space 10.

  The suction pipe 8 stored in the suction pipe storage space 10 in the above-described manner can be developed (drawn) as follows, for example. First, an operator (not shown) inserts a hand (arm) into the suction tube storage space 10 through the opening 11 opened to the rear (rear surface) of the vehicle 1, and the tip 8 b of the suction tube 8 stored in the suction tube storage space 10. [See FIG. 4 (a)]. Next, when the worker moves in a direction away from the vehicle 1 while holding the tip 8b of the suction pipe 8, the suction pipe 8 is pulled out from the storage space 10 for a predetermined length. When the suction pipe 8 is pulled out by a predetermined length, a twisted portion T is formed in the suction pipe 8 as shown in FIG. 4B, so that the suction pipe 8 is rotated in the circumferential direction (in the illustrated example, it is rotated counterclockwise). ) To remove the twisted portion T. Thereafter, when the operator further moves away from the vehicle 1 while holding the tip 8b of the suction pipe 8, the suction pipe 8 sequentially rotates from the suction pipe storage space 10 while rotating around the vertical axis with the base end 8a as a fulcrum. It is pulled out (see FIGS. 4C and 4D). When the suction pipe 8 drawn out from the suction pipe storage space 10 is stored in the suction pipe storage space 10, the procedure reverse to that in the case of developing the suction pipe 8 stored in the suction pipe storage space 10 may be taken.

  As described above, the suction tube storage space 10 is provided between the floor portion 5a of the cargo box 5 and the chassis frame 3 so that the suction tube 8 formed of a long tubular body having flexibility can be inserted and removed. If this is the case, the ground height at the storage position of the suction pipe 8 can be reduced to the operator's waist height or lower, and the base end 8a of the suction pipe 8 can be held by a rotating body that rotates about a vertical axis at a fixed point. Then, when the suction pipe 8 is deployed and stored, even the worker can safely perform the work of rotating the suction pipe 8 around the vertical axis with the base end 8a as a fulcrum or bending the suction pipe 8 along its longitudinal direction. And can be executed quickly. In particular, if the rotating body is a swivel joint 6 connected to the fixed pipe 7a on the suction side of the pump 7 as in the present embodiment, after the suction pipe 8 is deployed (after being pulled out from the suction pipe storage space 10). The trouble of connecting the proximal end 8a of the suction pipe 8 to the suction side of the pump 7 can be omitted, and if the swivel joint 6 as a rotating body is arranged on the side of the rear end of the vehicle 1, The swivel joint 6 can prevent as much as possible the situation that becomes an obstacle to enabling the above-described rotation / bending operation of the suction pipe 8 to be performed smoothly. Therefore, according to the present invention, as disclosed in Patent Document 2, the take-up body 8 is wound around the outer periphery so that the suction pipe 8 can be unwound and taken up, and the vehicle 1 is simplified, and the suction pipe 8 is developed. And storage can be executed safely and quickly even by one person. In addition, a cross-sectional area enlarging portion 14 that gradually increases the cross-sectional area of the suction tube storage space 10 in the direction orthogonal to the front-rear direction of the vehicle 1 as the opening 11 is approached is provided in the rear region of the vehicle 1 in the suction tube storage space 10. Therefore, in particular, the storing operation of the suction pipe 8 with respect to the suction pipe storage space 10 can be performed easily and quickly.

  Further, in the vehicle 1 according to the present invention, the suction pipe 8 is taken in and out (the suction pipe 8 is expanded and stored) with respect to the suction pipe storage space 10 through the opening 11 opened to the rear (rear surface) of the vehicle 1. Even when the vehicle 1 is stopped on a narrow road, the suction pipe 8 can be smoothly deployed and stored regardless of the obstacle on the side of the vehicle.

  Furthermore, by providing the suction pipe storage space 10 between the floor portion 5a of the packing box 5 and the chassis frame 3 that supports the packing box 5 from below, the packing box 5 is separated back and forth as in Patent Document 2. Therefore, it is possible to equip the large-capacity packing box 5 having a long longitudinal dimension of the vehicle 1. Therefore, the freedom degree of the accommodation mode of the accessories with respect to the packing box 5 improves, and the usability of the packing box 5 improves. Furthermore, because of the configuration of the present invention, a part of the outer surface of the vehicle 1 is not covered with the suction pipe 8, so that the entire outer surface of the vehicle 1 (the packing box 5) is used as an attachment part or a storage part for equipment. It can also be used.

  As described above, the present invention has a great feature in that the expansion of the suction pipe 8 and the speed of the storing operation are enabled. Therefore, among various vehicles, a fire truck (in this embodiment, the water tank 9 is mounted). This can be particularly preferably employed in a vehicle 1 that is required to rapidly deploy the suction pipe 8, such as a fire engine with a water tank.

  The vehicle 1 according to the first embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment. Hereinafter, although the vehicle 1 which concerns on other embodiment to which this invention is applied is demonstrated, the common reference number is attached | subjected to the site | part which plays the substantially same function as the vehicle 1 which concerns on 1st Embodiment mentioned above, Duplicate explanation is omitted.

  FIGS. 5A and 5B are a schematic side view and a schematic plan view, respectively, of the vehicle 1 according to the second embodiment of the present invention. The main difference between the vehicle 1 according to this embodiment and the vehicle 1 according to the first embodiment is that the frictional force reducing means for reducing the frictional force generated when the suction pipe 8 is taken in and out of the suction pipe storage space 10. Here, the free roller 21 rotating around the vertical axis is employed as the frictional force reducing means. A plurality of free rollers 21 are arranged on both sides of the suction pipe storage space 10 in the vehicle width direction. Here, a plurality of free rollers 21 are arranged at equal intervals along the front-rear direction of the vehicle 1. In this case, the housing 12 that defines the suction tube storage space 10 has a free roller 21 that rotates about a vertical axis added to a pair of left and right side plates 12a and 12b, an upper plate 12c, a bottom plate 12d, and a front plate 12e. A free roller 21 that rotates around a vertical axis may be arranged instead of the pair of left and right side plates 12a and 12b. According to such a configuration, it is possible to more easily and quickly perform the operation of taking in and out the suction pipe 8 with respect to the suction pipe storage space 10 (development and storage of the suction pipe 8).

  FIGS. 6A and 6B are a schematic side view and a schematic plan view of the vehicle 1 according to the third embodiment of the present invention, respectively. The vehicle 1 according to this embodiment differs from the vehicle 1 according to the first embodiment mainly in the same manner as the vehicle 1 according to the second embodiment shown in FIGS. 5 (a) and 5 (b). 10 is further provided with a frictional force reducing means for reducing the frictional force generated when the suction pipe 8 is taken in and out of the suction pipe 10. Here, the suction pipe 8 accommodated in the suction pipe storage space 10 is used as the frictional force reducing means. A free roller 22 that is rotatable about a horizontal axis extending in the vehicle width direction while being supported from below is adopted. A plurality of free rollers 22 are arranged along the front-rear direction of the vehicle 1. In this embodiment, a plurality of free rollers 22 are arranged at equal intervals along the front-rear direction of the vehicle 1. In this case, the housing 12 may be a pair of side plates 12a, 12b, an upper plate 12c, a bottom plate 12d, and a front plate 12e to which a free roller 22 that rotates about a horizontal axis is added, or instead of the bottom plate 12d. A free roller 22 that rotates about a horizontal axis may be disposed. According to such a configuration, similarly to the vehicle 1 according to the second embodiment shown in FIGS. 5A and 5B, the suction pipe 8 is taken in and out (the suction pipe 8 is expanded and stored) with respect to the suction pipe storage space 10. It can be performed more easily and quickly.

  In addition, although illustration is abbreviate | omitted, the vehicle 1 was shown in FIG. 5 (a) (b) as the frictional force reduction means, and the free roller 21 rotated around the vertical axis shown in FIG. It is also possible to provide both of the free rollers 22 that rotate around the horizontal axis. Further, as the frictional force reducing means, for example, a hard film having slidability formed in a portion of the housing 12 where the suction pipe 8 is in sliding contact can be adopted.

  FIG. 7 is a schematic plan view of the vehicle 1 according to the fourth embodiment of the present invention. The vehicle 1 according to this embodiment is different from the vehicle 1 according to the first embodiment in the cross-sectional area enlarged portion 14 in the suction tube storage space 10. To describe this difference in detail, in the vehicle rear side region of the pair of left and right side plates 12a, 12b constituting the housing 12, the opening dimension in the vehicle width direction of the suction pipe storage space 10 is gradually increased toward the rear side of the vehicle 1. By providing the inclined portions 12a1 and 12b1 that are inclined in the expanding direction, the cross-sectional area expanding portion 14 is formed. Said inclination part 12a1, 12b1 can also be additionally provided in the vehicle 1 which concerns on the 1st-3rd embodiment mentioned above (illustration omitted).

  FIG. 8 is a schematic plan view of the vehicle 1 according to the fifth embodiment of the present invention. The vehicle 1 according to this embodiment differs from the vehicle 1 according to the fourth embodiment shown in FIG. 7 in the manner in which the suction pipe 8 is stored in the suction pipe storage space 10. More specifically, when the suction pipe 8 accommodated in the suction pipe storage space 10 is pulled out (deployed), the suction pipe is provided in the suction pipe storage space 10 so that the twisted portion T as shown in FIG. 8 is stored. If the suction pipe 8 is accommodated in this manner, the removal work of the twisted portion T is not required when the suction pipe 8 is deployed, so that the suction pipe 8 can be deployed more easily and quickly. Of course, also in the vehicle 1 according to the first to third embodiments described above, the suction pipe 8 can be stored in the suction pipe storage space 10 in the storage mode as in this embodiment.

  FIGS. 9A and 9B are a schematic side view and a schematic plan view, respectively, of the vehicle 1 according to the sixth embodiment of the present invention. In this embodiment, in the vehicle 1 in which the cross-sectional shape of the suction tube storage space 10 is the same as that of the embodiment shown in FIGS. 7 and 8, one or a plurality (in the illustrated example, one in the illustrated example) extends in the suction tube storage space 10. ), The suction tube storage space 10 is divided into a first small storage space 10A located relatively above and a second small storage space 10B located relatively below. It is a thing. The two small storage spaces 10 </ b> A and 10 </ b> B divided in the vertical direction communicate with each other in the vehicle rear (rear end) side region of the suction tube storage space 10. In this case, the suction pipe 8 is first stored in a curved state in the first small storage space 10A including the proximal end 8a held (connected) by the swivel joint 6 and then the distal end 8b. The substantially half area in the longitudinal direction including is stored in the second small storage space 10B in a curved state.

  According to such a configuration, the suction pipe 8 can be accommodated so as to avoid the suction pipes 8 from contacting each other in the longitudinal direction. For this reason, the suction pipe 8 can be expanded and stored more quickly, and wear of the suction pipe 8 can be suppressed. Although illustration is omitted, also in this embodiment, either or both of the free rollers 21 and 22 as the frictional force reducing means shown in FIGS. 5 and 6 can be provided. Moreover, it is of course possible to apply the configuration of this embodiment to the vehicle 1 according to the various embodiments described above.

  Although the present invention has been described for the case where the present invention is applied to a fire engine with a water tank, the present invention is not limited to other fire engines equipped with suction pipes, for example, rescue work vehicles equipped with telescopic crane devices, refracting It can be preferably applied to an aerial work vehicle equipped with a type or telescopic ladder. In addition, the present invention is not limited to the above-described fire engine, but also includes a cargo box 5 having a floor portion 5a on which equipment is mounted, a chassis frame 3 that supports the cargo box 5 from below, and flexibility.
