DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding a hose for supplying a fire extinguishing fluid, and an unmanned fire engine equipped with the apparatus.

[0002]

2. Description of the Related Art In firefighting activities, fire extinguishing fluid may be supplied from a fire hydrant, river, or the like to a fire engine having fire extinguishing fluid discharge means by a long hose. As the fire-extinguishing fluid supply hose, a hose configured by connecting a plurality of flexible unit hoses with a connecting tool is used.

Conventionally, the hose has been manually delivered from the storage section.

[0004]

When the hose is sent out manually, the number of workers engaged in firefighting activities is reduced, and when the hose is long, very large labor is required.

In recent years, an unmanned fire engine equipped with a vehicle body that can be driven by remote control and fire extinguishing fluid discharge means provided on the vehicle body has been developed. When a hose connected to the fire extinguishing fluid discharge means of such an unmanned fire truck is manually delivered, the unmanned fire truck cannot be used in a high-temperature fire place where people cannot approach. Therefore, an unmanned fire truck intended for use at a high-temperature fire site cannot function as expected.

Further, when a fire extinguishing fluid is supplied to an unmanned fire engine via a hose, the evacuation of the unmanned fire engine from a fire spot may be hindered by the hose being caught by an obstacle.

An object of the present invention is to provide a hose delivery device and an unmanned fire engine capable of solving the above problems.

SUMMARY OF THE INVENTION The present invention is an apparatus for sending out a fire extinguishing fluid supply hose, which is constituted by connecting a plurality of flexible unit hoses with a connecting member, from a storage section, comprising: A rotating body and a second rotating body opposed to the first rotating body, at least one of the rotating bodies being displaceable in a direction approaching the other rotating body and in a direction away from the other rotating body. Means is provided for applying elastic force to make the two rotating bodies relatively close to each other so that the unit hose located between them can be sandwiched between the two rotating bodies, and the unit hose sandwiched between the two rotating bodies is sent in the delivery direction. As a result, at least one of the rotating bodies is driven to rotate, and means for detecting the coupling at a preset position before passing between the two rotating bodies is provided, and by detecting the coupling, That detection Is characterized in that the connector has means for relatively away is provided both rotating body so as to be passed through.

According to the structure of the present invention, the unit hose sandwiched between the two rotating bodies can be sent in the sending direction by the rotational drive of at least one of the rotating bodies. In a state where the unit hose passes between the two rotating bodies, it is possible to prevent the two rotating bodies from being relatively separated from each other by the elasticity. Next, when the connecting member of the unit hose is detected before passing between the two rotating members, the two rotating members are relatively separated from each other. Thereby, the connecting member can pass between the two rotating bodies by inertia. After the connecting tool passes between both rotating bodies, the interval between both rotating bodies is narrowed, and the unit hose is again sandwiched between both rotating bodies,
The hose can be sent in the delivery direction by the rotational drive of at least one of the rotating bodies.

An unmanned fire engine according to the present invention comprises a vehicle body which can be driven by remote control, fire extinguishing fluid discharge means provided on the vehicle body, and a hose for supplying a fire extinguishing fluid to the fire extinguishing fluid discharge means from outside the vehicle body. A hose storage part for storing a unit constituted by connecting a plurality of flexible unit hoses with a connector, and the fire extinguishing fluid supply hose of the present invention capable of sending the hose out of the vehicle body And a delivery device.

According to this configuration, the hose can be sent out from the unmanned fire engine without any manual operation, so that the unmanned fire engine can be used in a high-temperature fire place where no person can approach. Thereby, an unmanned fire truck intended for use in a high-temperature fire site can be made to perform its original function. It is preferable that the hose that supplies the fire-extinguishing fluid to the unmanned fire truck is detachable from the vehicle body of the unmanned fire truck by remote control. Accordingly, when the unmanned fire truck is evacuated from the fire site, the hose is remotely removed from the vehicle body, so that it is possible to prevent the evacuation of the unmanned fire truck from being hindered by the hose caught on an obstacle.

2. The first limit switch 133 and the second limit switch 149 are connected to the fire-fighting controller 24. When a remote control signal instructing detachment of the hose 103 is sent from the operating device 7 to the fire-fighting controller 24 via the wireless device 23, the electromagnetic detaching device 4
5 releases the fixing between the hose 103 and the hose connection portions 33 and 34.

Also, the hose 103 from the operating device 7
The remote control signal instructing the sending of the
3 to the fire-fighting controller 24 via
The rotating bodies 106 and 115 are rotationally driven by the drive motor 107 in the delivery direction, and the delivery of the hose 103 is started. In this state, the relative separation of the rotating bodies 106 and 115 is prevented by the elasticity of the spring 118. When the first limit switch 133 outputs a detection signal of the connecting member 103b after the hose 103 starts to be sent out, the fire-fighting controller 24 drives the motor cylinder 142 to extend it. As a result, the rotating bodies 106 and 115 are relatively separated from each other, and the connecting member 103b
Passes between the rotating bodies 106 and 115 by inertia.
When the set time has elapsed after the motor cylinder 142 is extended, the fire-fighting controller 24
42 is driven to reduce the size. The motor cylinder 142
When the second limit switch 149 in contact with the dog 148 outputs a return signal due to the reduction of the size, the fire-fighting controller 24 stops the motor cylinder 142. Thereby, after the connecting tool 103b passes between the two rotating bodies 106 and 115, the interval between the two rotating bodies 106 and 115 is reduced, and the unit hose 103a is again connected to the two rotating bodies 106 and 115.
And the hose 103 can be sent in the sending direction.

Further, the hose 103 from the operating device 7
The remote control signal instructing the winding of
Are sent to the fire-fighting system controller 24 via the drive motor 107, so that the two rotating bodies 106 and 115 are rotationally driven by the drive motor 107 in a direction opposite to the sending direction. Thereby, the hose 103 can be wound up. This hose 103
Is carried out only in a state where the unit hose 103a is sandwiched between both the rotating bodies 106 and 115 in order to remove slack generated when the hose 103 is sent out.

According to this configuration, the labor required for sending out the hose 103 becomes unnecessary, and the labor shortage can be solved. Further, since the hose 103 can be sent out from the unmanned fire truck 1 without manual operation, the unmanned fire truck 1 can be used in a high-temperature fire place where no person can approach. Thereby, the unmanned fire engine 1 intended to be used at a high-temperature fire site can perform its original function. In addition, when the unmanned fire truck 1 is evacuated from the fire site, the hose 103 is detached from the vehicle body 10 by remote control, whereby it is possible to prevent the evacuation by the hose 103 caught on an obstacle or the like. Moreover, even if the hose 103 is detached from the vehicle body 10, the self-defense fluid can be supplied from the tank 42 as described above.
While the unmanned fire truck 1 is evacuated from the fire site, the vehicle body 10
Can be protected from heat.

In the present embodiment, the water discharge gun 11 is
In FIG. 6, a controller 27 of the drive device 150 is connected to the wireless device 23 so as to be rotatable about the vertical axis and swingable about the horizontal axis via an electronically controlled drive device 150. The direction of water discharge by the water discharge gun 11 can be remotely controlled by a remote control signal from the operation device 7.

In the above embodiment, the transport vehicle 3
The remote control signal can be transmitted not only from the control device 7 of the remote control room 5 but also from a portable control device (not shown).

The present invention is not limited to the above embodiment. For example, the number and arrangement of the means for discharging the self-defense fluid are not particularly limited. Further, the guidance signal generating unit is not limited to a configuration including a magnet, and may generate an optical signal as a guidance signal, for example. Further, both rotating bodies of the hose feeding device may be driven, or may be displaced in a direction approaching and separating from each other, or the coupling may be detected by a non-contact sensor.
