Description

Technical Field

[0001] The present invention relates to a fire and rescue vehicle, and more particularly to a fire and rescue vehicle capable of storing a large number of equipment items required for fire fighting activities and rescue activities, and enabling the simultaneous performance of fire fighting activities and rescue activities.

Background Art

[0002] Generally, as vehicles that are dispatched during disasters such as fires, earthquakes, and accidents, there are fire pump trucks equipped with fire pumps for fire fighting activities and rescue work vehicles equipped with various equipment and tools for rescue activities (see, for example, Patent Documents 1 and 2). In contrast, there is a demand for the provision of a fire and rescue vehicle capable of simultaneously performing not only fire fighting activities but also rescue activities during a disaster.

[0003] Such a fire and rescue vehicle needs to carry a large number of equipment items in order to simultaneously perform fire fighting activities and rescue activities, and for that, it is necessary to secure a space for storing all the equipment items. However, in conventional fire pump trucks, many of the mounted fire pumps are arranged on the upper part of the chassis, and it is difficult to secure a space for storing rescue equipment newly required for rescue activities. On the other hand, although conventional rescue work vehicles have relatively large storage compartments, since a large number of equipment and tools required for rescue activities are stored in those storage compartments, it is difficult to secure a space for newly mounting a fire pump, a fire hose, etc.

Summary of the Invention

Problems to be Solved by the Invention

[0005] An object of the present invention is to provide a fire and rescue vehicle capable of storing a large number of equipment items necessary for fire fighting activities and rescue activities, and enabling the fire fighting activities and rescue activities to be carried out simultaneously.

Means for Solving the Problems

[0006] The fire and rescue vehicle of the present invention for achieving the above object includes a main frame equipped with a traveling engine, a sub-frame disposed on the upper part of the main frame, a storage provided on the upper part of the sub-frame for storing equipment items used for fire fighting activities and rescue activities, and a fire pump disposed inside the vehicle width direction of the main frame and / or the sub-frame below the storage and behind the rear wheels. The fire pump is connected to the PTO shaft of the traveling engine and driven by the traveling engine, and communicates with a water discharge port and a water suction port that open rearward. The PTO shaft has a plurality of propeller shafts and a center bearing that connects these propeller shafts to each other. and, among the plurality of propeller shafts, the propeller shaft adjacent to the fire pump is inclined downward from the extending direction of the main frame toward the rear of the vehicle It is characterized by the above.

Effects of the Invention

[0007] In the present invention, there are provided a main frame equipped with a traveling engine, a sub-frame disposed above the main frame, a storage compartment disposed above the sub-frame for storing equipment used for fire-fighting activities and rescue activities, and a fire pump disposed inside the main frame and / or the sub-frame in the vehicle width direction below the storage compartment and behind the rear wheels. The fire pump is connected to the PTO shaft of the traveling engine and driven by the traveling engine, and communicates with a water discharge port and a water suction port that open rearward. The PTO shaft has a plurality of propeller shafts and a center bearing that connects these propeller shafts to each other. Therefore, the upper part of the sub-frame can be utilized as a storage compartment for storing equipment necessary for fire-fighting activities and rescue activities, and the space available as a storage compartment is not narrowed due to the arrangement of the fire pump. For example, when the present invention is applied to a conventional fire pump vehicle, since the fire pump is disposed inside the main frame and / or the sub-frame in the vehicle width direction below the storage compartment and behind the rear wheels, the space for storing newly required equipment for rescue activities can be effectively utilized. On the other hand, when the present invention is applied to a conventional rescue vehicle, since the fire pump is disposed inside the main frame and / or the sub-frame in the vehicle width direction below the storage compartment and behind the rear wheels, in addition to rescue activities, fire-fighting activities can be carried out simultaneously, and equipment necessary for fire-fighting activities such as a fire hose can be stored. Therefore, according to the fire and rescue vehicle according to the present invention, a large number of equipment necessary for fire-fighting activities and rescue activities can be mounted, and fire-fighting activities and rescue activities can be carried out simultaneously. Also, in the event of a disaster, conventionally, it was necessary to dispatch both a fire pump vehicle and a rescue vehicle, but according to the fire and rescue vehicle according to the present invention, only one vehicle is required, so the number of vehicles and personnel can be reduced.

[0008] In the fire rescue vehicle of the present invention, it is preferable that the propeller shaft is configured to be continuously usable in a non-lubricated state. Conventional propeller shafts need to be lubricated regularly, which requires maintenance effort and time. However, the propeller shaft installed in the fire rescue vehicle according to the present invention can be continuously used in a non-lubricated state, eliminating the need for regular maintenance. In addition, by using a propeller shaft that can be continuously used in a non-lubricated state, the space required for lubrication work can be saved. As a result, the propeller shaft can be arranged close to the floor under the storage compartment. Furthermore, the storage compartment can be directly attached to the sub-frame. Alternatively, the height of the sub-frame can be reduced, and the space of the storage compartment can be increased.

[0009] It is preferable that a cross beam extending in the vehicle width direction is arranged on the sub-frame, and the fire pump is fixed to the cross beam. Thereby, even when the fire pump cannot be attached to the main frame due to the vehicle structure, the fire pump can be arranged at an arbitrary position.

[0010] Among the plurality of propeller shafts, it is preferable that the propeller shaft adjacent to the fire pump is inclined downward from the extending direction of the main frame toward the rear of the vehicle. When arranging the fire pump below the storage compartment and behind the rear wheels, the arrangement of the propeller shaft can be simplified while the fire pump can be arranged at a predetermined position.

[0011] The inclination angle of the propeller shaft adjacent to the fire pump with respect to the extending direction of the main frame is preferably 7° or less. Thereby, while appropriately transmitting the power of the driving engine to the fire pump by the propeller shaft, the fire pump can be arranged at an arbitrary position according to the vehicle structure.

Embodiments for Carrying Out the Invention

[0013] Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, a fire rescue vehicle (vehicle 1) according to an embodiment of the present invention includes a pair of main frames 2a that extend in the longitudinal direction of the vehicle 1 and mount a traveling engine E, and a pair of sub-frames 2b disposed in parallel with the main frame 2a above the main frame 2a. That is, the vehicle 1 has a chassis 2 having a two-stage structure composed of the main frame 2a and the sub-frame 2b. On the upper part of the chassis 2, a cabin 3 which is a space for crew members to board is arranged at the front with respect to the vehicle traveling direction D, and a storage 4 for storing equipment used for fire fighting activities and rescue activities is arranged at the rear with respect to the vehicle traveling direction D. Note that the vehicle width direction W is a direction orthogonal to both the vehicle traveling direction D and the vehicle height direction H.

[0014] The main frame 2a and the sub-frame 2b are arranged so as to be in substantially the same position in the vehicle width direction W. On the other hand, the main frame 2a and the sub-frame 2b have different lengths from each other. In the illustrated example, they are positioned in the order of the front end portion (front end) of the main frame 2a in the vehicle front, the front end portion of the sub-frame 2b, the rear end portion (rear end) of the main frame 2a in the vehicle rear, and the rear end portion of the sub-frame 2b, starting from the front of the vehicle. The rear end portion of the main frame 2a is arranged behind the rear wheels, the front end portion of the sub-frame 2b is arranged between the cabin 3 and the storage 4, and the rear end portion of the sub-frame 2b is arranged at substantially the same position as the rear end portion of the storage 4. The main frame 2a and the sub-frame 2b may be spaced apart in the vertical direction, but it is preferable that the sub-frame 2b is arranged to abut against the main frame 2a. When the sub-frame 2b is arranged to abut against the main frame 2a, the height of the upper end surface of the sub-frame 2b can be lowered, so that the space available as the storage 4 can be increased, and the space for storing equipment can be increased. Further, cross beams 2c and 2d extending in the direction orthogonal to the extending direction thereof (vehicle width direction W) are provided on the sub-frame 2b.

[0015] Examples of the equipment stored in the storage 4 include a fire hose, a fire suction pipe, a pipe gun (with nozzle), and various intermediate fittings for use in fire fighting activities, and a hydraulic cutter, a hydraulic spreader, an engine cutter, a gas cutter, and a chainsaw for use in rescue activities.

[0016] As shown in FIGS. 2 and 3, a fire pump 10 is disposed inside the pair of sub-frames 2b in the vehicle width direction. The fire pump 10 is disposed at the lower part of the storage 4 and is fixed to the cross beam 2c from below. The fire pump 10 is disposed at the rear part of the vehicle 1 (chassis 2) with respect to the vehicle traveling direction D. More specifically, the fire pump 10 is disposed behind the rear wheels of the vehicle 1 and is arranged so as not to protrude rearward of the rear end of the vehicle 1. Further, the fire pump 10 is connected to the PTO shaft 5 of the traveling engine E and is driven by the traveling engine E. Furthermore, the portion P of the fire pump 10 connected to the PTO shaft 5 of the traveling engine E faces forward with respect to the vehicle traveling direction D. The PTO shaft 5 is a mechanism capable of taking out the power of the traveling engine E of the vehicle 1 to drive other mechanical devices, and there are a side PTO, a flywheel PTO, etc. according to the application. Note that FIG. 3 is a plan view seen from below the vehicle.

[0017] The PTO shaft 5 is composed of a plurality of (three in FIG. 2) propeller shafts 5a, 5b, 5c and at least one (two in FIG. 2) center bearing 5x, 5y connecting them to each other.

[0018] The propeller shafts 5a, 5b, and 5c are rotating shafts for transmitting the power of the traveling engine E to the fire pump 10. In the present invention, for example, a propeller shaft having the shaft structure shown in FIG. 4 can be used. As shown in FIG. 4, the propeller shaft 5a mainly includes a cylindrical cover 51, a shaft 52 disposed inside thereof and configured to be variable in length, a pair of joint kits 53 disposed at both ends thereof, and a pair of yokes 54 disposed outside thereof and connected to other members. The other propeller shafts 5b and 5c also have the same shaft structure as the propeller shaft 5a. The propeller shafts 5a, 5b, and 5c are all configured to be continuously usable in a non-lubricated state. That is, as shown in FIG. 7, in the conventional propeller shaft 100, an oil supply port 101 for supplying lubricating oil is provided, whereas the propeller shafts 5a, 5b, and 5c according to the present invention do not require oil supply, so no oil supply port is provided. The propeller shafts 5a, 5b, and 5c are coated with a thermoplastic resin powder paint made of polyamide 11, so they are excellent in water resistance and heat resistance, and grease is sealed, so no oil supply is required.

[0019] As shown in FIG. 2, the propeller shafts 5a and 5b are arranged along the extending direction of the main frame 2a, while the propeller shaft 5c adjacent to the fire pump 10 is arranged to incline downward from the extending direction of the main frame 2a toward the rear of the vehicle 1 in order to be connected to the fire pump 10. The inclination angle θ of the propeller shaft 5c with respect to the horizontal direction is preferably, for example, 7° or less, and more preferably 2° or less. Further, as shown in FIG. 3, the propeller shafts 5a, 5b, and 5c extend substantially parallel to the sub-frame 2b.

[0020] The center bearings 5x and 5y are connecting members that connect two adjacent propeller shafts and transmit torque smoothly. Even when the two adjacent propeller shafts are not arranged on the same axis, they can be connected. In the present invention, for example, a center bearing having the structure shown in FIG. 5 can be used. Further, as shown in FIG. 3, the center bearings 5x and 5y are arranged on a cross beam 2d that spans in a direction orthogonal to the sub-frame 2b.

[0021] The fire pump 10 communicates with a water discharge port 21 and a water suction port 22. That is, the water discharge port 21 and the water suction port 22 communicate with the fire pump 10 via a water discharge pipe 31 and a water suction pipe 32 made of metal (for example, iron), respectively. The water discharge pipe 31 is a branched pipe arranged between the water discharge port 21 and the water discharge connection portion 11 in the fire pump 10, and the water suction pipe 32 is a branched pipe arranged between the water suction port 22 and the water suction connection portion 12 in the fire pump 10. Further, the water discharge connection portion 11 connected to the water discharge pipe 31 opens upward in the vertical direction, and the water suction connection portion 12 connected to the water suction pipe 32 opens in the horizontal direction. A check valve 23 is attached to the water discharge connection portion 11, and when the running engine E stops, the check valve 23 automatically seals the water discharge pipe 31 to prevent the water in the fire pump 10 from flowing back. Further, at the time of draining, a fire hose is connected to the water discharge port 21, and a rubber suction pipe is connected to the water suction port 22 and used. The water discharge port 21 and the water suction port 22 can be arranged at desired positions and in desired directions according to the structure of the vehicle 1, and the number of ports of the water discharge port 21 and the water suction port 22 can also be increased as appropriate. In the embodiment of FIG. 2, both the water discharge port 21 and the water suction port 22 open rearward with respect to the vehicle traveling direction D.

[0022] Further, as shown in FIG. 6, the fire pump 10 has an annular pump housing 13. The pump housing 13 is provided with a plurality of drain outlets 14 for discharging the drain accumulated in the fire pump 10. These drain outlets 14 are arranged at intervals on the circumference of the pump housing 13. A valve 15 is attached to any one of the plurality of drain outlets 14, and that drain outlet 14 is in a usable state, while the drain outlets 14 to which the valve 15 is not attached are in a sealed state so that no drain is discharged from these drain outlets 14. That is, among the plurality of drain outlets 14, those located at positions suitable for the structure of the vehicle 1 can be selectively used. In the embodiment of FIG. 6, a valve 15 is attached to the drain outlet 14 located at the lowermost part of the fire pump 10.

[0023] With such drain outlets 14, it is possible to discharge the drain accumulated in the fire pump 10 through the valve 15 after using the fire pump 10. For example, when using water containing salt as a water source in fire extinguishing activities, the metal forming the fire pump 10 is likely to be corroded by the salt, so it is necessary to quickly discharge the drain after using the fire pump 10. On the other hand, in fire fighting activities in winter, the presence of the drain can prevent the water in the fire pump 10 from freezing. Therefore, the fire pump 10 has a structure that can discharge the drain in a timely manner as needed.

[0024] The fire pump 10 is a centrifugal pump having a single impeller 16. A plurality of blades 16a are arranged radially with respect to the central axis on this impeller 16. When the impeller 16 rotates, the flow velocity of the water in the impeller 16 is increased. As a result, the water in the fire pump 10 is discharged from the water discharge port 21 through the water discharge pipe 31. Further, the fire pump 10 includes a gearbox that converts the rotational speed of the PTO shaft 5 into a rotational speed suitable for the fire pump 10, a vacuum pump driven by the driving force of the PTO shaft 5, a vacuum pipe connecting between the vacuum pump and the pump housing 13, and the like.

[0025] Vehicle 1 is provided with at least one operation panel 24 for operating the fire pump 10. The operation panel 24 is preferably arranged at the rear of the vehicle 1 in the same manner as the fire pump 10, but is not particularly limited, and can be provided on one or both of the left and right side surfaces facing the vehicle traveling direction D as other installation locations. In any case, by reducing the installation locations of the operation panel 24, more space for storing equipment can be secured.

[0026] When discharging water in a fire fighting operation using the above fire pump, the traveling engine E is started, the vacuum pump is operated by the driving force of the PTO shaft 5 to remove the air in the fire pump 10 and the water suction pipe 32, and after the fire pump 10 and the water suction pipe 32 are filled with water, the impeller 16 is rotated by the driving force of the PTO shaft 5, water is discharged from the water discharge port 21, and water discharge is started from the fire hose connected to the water discharge port 21. By operating the operation panel 24, water discharge can be performed using the fire pump 10 as described above.

[0027] In the above-described fire and rescue vehicle, a main frame 2a equipped with a traveling engine E, a sub-frame 2b disposed above the main frame 2a, a storage 4 disposed above the sub-frame 2b for storing equipment used for fire fighting activities and rescue activities, and a fire pump 10 disposed inside the vehicle width direction of the main frame 2a and / or the sub-frame 2b below the storage 4 and behind the rear wheels. The fire pump 10 is connected to the PTO shaft 5 of the traveling engine E and driven by the traveling engine E, and communicates with a water discharge port 21 and a water suction port 22 that open rearward. The PTO shaft 5 has a plurality of propeller shafts 5a, 5b, 5c and center bearings 5x, 5y that connect these propeller shafts 5a, 5b, 5c to each other. Therefore, the upper part of the sub-frame 2b can be utilized as a storage 4 for storing equipment necessary for fire fighting activities and rescue activities, and the space available as the storage 4 is not narrowed by the arrangement of the fire pump 10. For example, when the present invention is applied to a conventional fire pump vehicle, since the fire pump 10 is disposed inside the vehicle width direction of the main frame 2a and / or the sub-frame 2b below the storage 4 and behind the rear wheels, a space for storing equipment necessary for new rescue activities can be effectively utilized. On the other hand, when the present invention is applied to a conventional rescue work vehicle, since the fire pump 10 is disposed inside the vehicle width direction of the main frame 2a and / or the sub-frame 2b below the storage 4 and behind the rear wheels, in addition to rescue activities, fire fighting activities can be carried out simultaneously, and equipment necessary for fire fighting activities such as fire hoses can be stored. Therefore, according to the fire and rescue vehicle according to the present invention, a large number of equipment necessary for fire fighting activities and rescue activities can be mounted, and fire fighting activities and rescue activities can be carried out simultaneously. Also, in the event of a disaster, conventionally, it was necessary to dispatch both a fire pump vehicle and a rescue work vehicle, but according to the fire and rescue vehicle according to the present invention, only one vehicle is required, so the number of vehicles and personnel can be reduced.

[0028] In the above-described fire rescue vehicle, the propeller shafts 5a, 5b, and 5c are all configured to be continuously usable without refueling. Conventional propeller shafts require regular refueling, which is time-consuming and laborious for maintenance. However, the propeller shafts 5a, 5b, and 5c mounted on the fire rescue vehicle according to the present invention can be continuously used without refueling, so regular maintenance is unnecessary. For example, it is suitable for cases where other members get in the way and physical refueling of the propeller shaft is impossible, such as the propeller shafts 5a, 5b, and 5c arranged inside the vehicle width direction of the main frame 2a and / or the sub-frame 2b. Also, by using the propeller shafts 5a, 5b, and 5c that can be continuously used without refueling, the space required for refueling operations can be saved. As a result, the propeller shafts 5a, 5b, and 5c can be arranged close to the floor under the storage compartment 4. Furthermore, the storage compartment 4 can be directly attached to the sub-frame 2b. Alternatively, there is an advantage that the height of the sub-frame 2b can be lowered and the space of the storage compartment 4 can be made larger.

[0029] Also, the fire pump 10 is fixed to the cross beam 2c arranged on the sub-frame 2b. By fixing the fire pump 10 in this way, even when the fire pump 10 cannot be attached to the main frame 2a due to the structure of the vehicle 1, the fire pump 10 can be arranged at an arbitrary position. On the other hand, when the fire pump 10 is arranged with respect to the main frame 2a, there are many parts of the fire pump 10 that protrude below the main frame 2a, and there is a possibility that the fire pump 10 comes into contact with the ground and is damaged during running.

[0030] Among the propeller shafts 5a, 5b, and 5c, the propeller shaft 5c adjacent to the fire pump 10 is inclined downward from the extending direction of the main frame 2a toward the rear of the vehicle 1. By arranging the propeller shaft 5c in this way, when the fire pump 10 is arranged below the storage compartment 4 and behind the rear wheels, the arrangement of the propeller shafts 5a, 5b, and 5c can be simplified while the fire pump 10 can be arranged at a predetermined position.

[0031] Furthermore, the inclination angle θ of the propeller shaft 5c adjacent to the fire pump 10 is set to 7° or less with respect to the extending direction of the main frame 2a. By appropriately setting the inclination angle θ of the propeller shaft 5c with respect to the extending direction of the main frame 2a in this way, while appropriately transmitting the power of the traveling engine E to the fire pump 10 by the propeller shafts 5a, 5b, 5c, the fire pump 10 can be arranged at an arbitrary position according to the structure of the vehicle 1. Here, if the inclination angle θ of the propeller shaft 5c exceeds 7°, the fire pump 10 will be arranged considerably lower than the main frame 2a, and there is a possibility that the fire pump 10 will come into contact with the ground and be damaged during traveling, which is not preferable.

[0032] In FIGS. 1 to 6, the fire pump 10 is arranged at the rear part of the chassis 2 with respect to the vehicle traveling direction D. By arranging the fire pump 10 at the rear part of the chassis 2 in this way, both water discharge and water suction can be performed from the rear part of the vehicle 1. Also, compared with the case where the fire pump 10 is arranged at the central part of the vehicle 1, the piping (the water discharge pipe 31 and the water suction pipe 32) from the fire pump 10 can be configured to be short and simple, so that the space for storing equipment can be increased.

[0033] Also, in the fire pump 10, the water discharge port 21 and the water suction port 22 are opened rearward with respect to the vehicle traveling direction D. By arranging the water discharge port 21 and the water suction port 22 in this way, the piping (the water discharge pipe 31 and the water suction pipe 32) from the fire pump 10 can be configured to be short and simple, so that the space for storing equipment can be increased.

[0034] Furthermore, the fire pump 10 has a plurality of discharge ports 14 for discharging drain, and these discharge ports 14 are arranged at intervals on the circumference of the annular pump housing 13. A valve 15 is attached to any one of the discharge ports 14, and the remaining discharge ports 14 are blocked. By configuring the discharge ports 14 in this way, the position of the discharge ports 14 can be selected according to the structure of the vehicle 1, so that the orientation and arrangement of the fire pump 10 can be appropriately changed.

[0035] In the above fire rescue vehicle, the fire pump 10 is preferably a centrifugal pump having a single impeller 16. On the other hand, there are generally centrifugal pumps having a plurality of impellers. However, for centrifugal pumps having a plurality of impellers, the entire device including the piping from the water discharge port to the water suction port becomes large, which is disadvantageous in securing space. In the present invention, by configuring the fire pump 10 as a centrifugal pump having a single impeller 16, the fire pump 10 can be miniaturized, and the space for storing equipment can be increased.

[0036] In the above description, an example in which the fire pump 10 is arranged inside the vehicle width direction of the pair of sub-frames 2b is shown, but the present invention is not limited to this. The fire pump 10 may be arranged inside the vehicle width direction of both the pair of main frames 2a and the pair of sub-frames 2b, or the fire pump 10 may be arranged inside the vehicle width direction of the pair of main frames 2a. Further, an example in which the propeller shaft 5c and the fire pump 10 are connected is shown, but the present invention is not limited to this. A gear box may be interposed between the propeller shaft 5c and the fire pump 10. In that case, the propeller shaft 5c can be arranged parallel to the extending direction of the main frame 2a.
