Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hose car that is loaded and carried on a fire engine, and more particularly to a hose car that can be stood and stacked easily while being powered.
[0002]
[Prior art]
Fire engines usually run with a hose car containing a hose. During fire extinguishing activities, the hose car is lowered near the fire site, the hose car is run to the fire site while the hose connected to one end of the fire engine is deployed, and water discharge is started from the nozzle at the tip of the hose after arrival at the fire site. Is to do.
[0003]
As this hose car, a manual hose car towed by human power as shown in FIG. 5 has been used. In the figure, 20 is a main body, 21 is a handle, and 22 is a wheel. The main body 20 has a box shape and can accommodate a hose therein.
[0004]
Since the guide hose car as shown in FIG. 5 is lightweight, there is an advantage that it can be stood and loaded easily on the rear step of the fire fighting vehicle.
[0005]
However, in recent years, a power type has been used in many cases instead of such a guide type hose car. This is because firefighters are aging in recent years, and it is intended to prevent the exhaustion of the members' physical strength when performing fire fighting activities.
[0006]
FIGS. 6 and 7 illustrate such a power hose car. 6 is a front view of the power hose car, and FIG. 7 is a right side view thereof. In this powered hose car, the driver operates the riding handle 32 on the step 31, and the wheels 34 have four wheels. Further, the hose is accommodated in the box-shaped main body 33.
[0007]
[Problems to be solved by the invention]
However, the conventional power hose car has the following problems.
[0008]
Because it is a four-wheeled vehicle and can be ridden, it becomes heavy. In other words, a disc brake is used as a brake, an electromagnetic brake is used as a parking brake, a reduction mechanism must be provided as a power transmission device, and it is necessary to provide a riding step having a strength that can withstand the weight of the passenger. It is necessary to equip a full-fledged steering mechanism because of the four wheels, etc., and it is necessary to equip various mechanisms.
[0009]
Since the weight is so large, there is a problem that it is difficult to travel on a steep slope or a rough road. Especially when used on downhill roads on freezing roads and snowy roads in winter, there is a great danger for members who operate hose cars.
[0010]
It is necessary to attach a large hydraulic lifting device for loading and unloading the hose car to and from the fire truck, and the installation space for that will significantly limit the loading space for other materials and equipment.
[0011]
Due to the weight of the hose car and hydraulic lifting device, the total weight of the fire engine increases and the climbing ability decreases.
[0012]
Since the hose car and the hydraulic lifting device are loaded on the rear part of the fire engine, the vehicle balance is deteriorated.
[0013]
When a new fire truck is purchased, it is necessary to make a major refurbishment of the fire truck, resulting in high costs.
[0014]
In order to remodel an existing non-powered hose car loaded vehicle and enable loading of a powered hose car, a large-scale refurbishment of the fire engine is necessary. Since the use of the vehicle becomes impossible, such a renovation is impossible as a real problem.
[0015]
Conventional power hose cars have poor motor capacity compared to weight, so the climbing ability is poor and may not withstand use in mountainous areas.
[0016]
Accordingly, an object of the present invention is to provide a power hose car that can solve the above-mentioned problems in the conventional power hose car.
[0017]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the hose car according to the present invention allows the handle part for pulling and operating the hose car to be rotated, thereby positioning the handle part in both the hose car traveling direction and the direction opposite to the traveling direction. In order to reduce the weight, a two-wheel walking type is adopted, and a control valve type battery is adopted to enable a stowage loading on a fire-fighting vehicle, a pulling part can be folded, and a fire hose is stored. The main body to be used was a box, and a high-power motor was used as a prime mover. The following describes how the solving means works to solve the problem.
[0018]
In the present invention, the handle portion for pulling the hose car can be rotated, so that the handle portion can be positioned in both the traveling direction and the reverse direction of the hose car. This makes it possible for a member operating a hose car to operate a hose car from the rear of a hose car on a downhill on a frozen road or snowy road in winter, even if a hose car slips or a member who operates a hose car falls. , There is no risk that members will be caught in a hose car or caught in a hose car.
[0019]
The hose car according to the present invention is a two-wheel walking type in order to reduce the weight. Therefore, the weight of the hose car is light. Therefore, driving on steep slopes and rough roads becomes easy.
[0020]
In addition, the hose car itself is lightweight, and furthermore, a control valve type battery is adopted in order to make it possible to lean on the fire engine, and the handle can be folded to make it possible to lean on the fire engine, Similarly, the main body for storing a fire hose or the like is used as a box in order to be able to stand on a fire engine .
[0021]
The battery does not leak even when stood and stacked by using a control valve type battery, the handle part can be folded, so the storage space is small, and the main body is a box, so it can be stood and stacked. However, the fire hose stored in the main body does not leak out.
[0022]
Thus, the hose car according to the present invention can be stood and loaded on the rear step of the fire engine.
[0023]
Therefore, it is no longer necessary to install a large hydraulic lifting device for loading and unloading the hose car on the fire truck, and the installation space for the hydraulic lifting device is not required, so the loading space for other materials and equipment is limited. It will not happen.
[0024]
Furthermore, the hose car itself is lighter, and the total weight of the fire engine can be reduced because no hydraulic lifting device is required, and the climbing ability of the fire engine will not be reduced. It is only necessary to load the materials and equipment, so there is no loss of vehicle balance.
[0025]
Further, since it is not necessary to install a hydraulic lifting device or the like, there is no need to make a major refurbishment of the fire fighting vehicle when purchasing a new fire fighting vehicle.
[0026]
Similarly, since there is no need to install a hydraulic lift, etc., the existing non-powered hose car loaded vehicle will be remodeled and the fire engine will be extensively refurbished to enable loading of the powered hose car according to the present invention. This is not necessary, and therefore the cost burden is small, and the refurbishment period is short, so the period during which the fire truck cannot be used is short.
[0027]
In addition, the hose car itself is lighter, and since it uses a high-power motor, it has excellent climbing ability. A conventional power hose car has a climbing ability of about 10 degrees, whereas a conventional hose car has a climbing ability of about 30 degrees.
[0028]
In this way, the hose car according to the present invention can solve the above-mentioned problems of the conventional power hose car.
[0029]
