The present invention will be described in detail below with reference to the embodiments shown in the drawings. FIG. 1 and FIG. 2 exemplify a mobile vehicle that implements the method for collecting water supply hoses for fire fighting according to the present invention. This moving vehicle is provided with a driver's cab 2 in the front part of a vehicle body 1, a hose container 3 in the rear part thereof, and a hose retracting mechanism 4 in the front part of the hose container 3. When the moving vehicle does not collect the water supply hose (fire hose), the hose retracting mechanism 4 is stored in a lowered position as shown by a chain line in the storage box 5 in the center of the front part of the hose container, and the water supply hose ( When collecting fire hose), it goes up and moves to either one of the left and right ends and is set at that end. Moreover, the hose retracting mechanism 4 is tiltable inward at the set position on the rear side within a range of 0 ° to 60 °, preferably 0 ° to 30 ° with respect to the vehicle traveling direction.

As shown in FIG. 3, the hose retracting mechanism 4 is
A driving roller 41 and a pair of nip rollers 41 ′ that open and close up and down, and a driving roller 42 and a pair of nip rollers 42 ′ that open and close in the same manner are arranged in two stages in the front-rear direction, and the front side of each pair of rollers The sensors 43 and 44 for detecting the connection fitting M of the water supply hose H are arranged. The sensors 43 and 44 are adapted to detect the passage of the water supply hose by swinging when the connection fitting M of the water supply hose comes into contact therewith.

The drive rollers 41, 42 are positively driven by a motor or the like (not shown), and the nip rollers 41 ', 4 are
The 2'is designed to open and close vertically by a hydraulic cylinder or an electric drive system. The sensors 43 and 44 are not limited to the swing type shown in the figure, and any known sensor such as an optical sensor, a metal detection sensor, a limit switch, a pressure sensor, and a sound wave sensor can be used.

By the detection signals of the sensors 43 and 44, the nip rollers 41 'and 42' of each pair of rollers are opened upward with a time lag via a control unit (not shown) so that the connection fittings M can be sequentially passed. To do. That is, since the two-stage assembly roller is arranged at a front and back with a space, when the front sensor 43 detects the passage of the connection fitting M, the nip roller 41 ′ of the front assembly roller opens to open the connection fitting M. Sensor, then the rear sensor 4
4 detects the passage of the connection fitting M, opens the nip roller 42 'of the rear assembly roller, and allows the connection fitting M to pass.

Since the nip rollers 41 'and 42' of the front and rear two-stage paired rollers are sequentially opened with a time difference as described above, when one is open, the other is always closed so that the water supply hose H is not closed. Transfer reliably and continuously without interruption. Also, the nip rollers 41 ', 42'
Is to press the water supply hose H together with the above-mentioned carrying action,
By this pressing action, the water remaining inside is pushed out,
It is not carried into the hose container 3.

When recovering the water supply hose H left between the water source and the fire site after the fire extinguishing work (or after the fire extinguishing training) using the above-described mobile vehicle of the present invention, first, the water supply hose H is Check whether it is left on the road left or right, and then raise the hose retracting mechanism 4 stored in the hangar 5 to the upper end of the hose container 3,
From there, the water supply hose H on the road is moved to one side of the set positions of the left and right ends of the hose container 3, and the rear end side is inclined slightly inward with respect to the vehicle traveling direction. It is preferable to move it to the end on the driver's side.

While the moving vehicle having the hose retracting mechanism 4 set at the end position as described above is advanced forward F along the road surface, the hose retracting mechanism 4 pulls up the water supply hose H and collects it in the hose container 3. To do. To collect the water in the hose container 3, another worker who has entered the hose container 3 sends out the water supply hose H from the hose retracting mechanism 4.
