Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hose cleaning device suitable for application to fire hoses and the like.

[Prior art] Conventionally, the hose for fire fighting used for fire extinguishing activities was manually washed, but the surface of the wound hose or piled hose is manually washed with a brush etc. Was an extremely troublesome and time-consuming task.

Therefore, for example, an electric hose washing device as disclosed in Japanese Utility Model Laid-Open No. 63-8058 has been proposed. This hose washing device is provided with a washing machine main body that houses a pair of rotating brushes that are driven to rotate by a motor, and a turntable that horizontally projects laterally from the main body. After unwinding the unwashed hose by rotating the turntable and placing it on the roll, guide it into the main body, wash it with a rotating brush, then discharge it outside the main body and store it in a basket for drying. It is configured.

[Problems to be solved by the invention] However, in such a conventional hose cleaning device, the entire device including the turntable is large,
There is a problem that the hose cannot be unwound smoothly because not only the installation space and the occupied space for storing the hose become large, but also the hose is guided into the main body in a twisted state. Further, since only one hose can be washed at a time, there is a problem that workability is extremely poor.

Therefore, a hose cleaning device capable of cleaning two hoses at the same time has also been proposed (Japanese Utility Model Publication No. 56-34760), but this device simply drains an uncleaned hose and draws it into the main body. However, there was a problem that long hoses were scattered around the device and the hoses were entangled with each other.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to wash two or more hoses at the same time, thereby improving the efficiency of the washing work. An object of the present invention is to provide a hose cleaning device that can reduce the storage space of the entire device.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a hose storage box whose upper surface is opened at the time of withdrawal so that the hose storage box can be freely drawn out from the main body of the washing machine. The inside of the hose is defined by a partition member into a plurality of hose storage chambers arranged in parallel in a direction orthogonal to the hose transport direction.

[Operation] When cleaning the hose, the hose stored in the hose storage box is guided to the cleaning device and cleaned. The unwashed hose is stored in each hose storage chamber defined by the partition member of the hose storage box and is pulled out at the time of cleaning.

Then, when the upper lid 5 is closed, the upper brush 24 and the lower brush 22 are in contact with each other via the hose 12 with their bristles crossing each other, and the upper roller 25 is pressed against the lower roller 23 by the compression coil spring 26. Also, the sprocket 27E is the chain 3 between the idler sprockets 28a and 28b.
Pressed against 1 and meshed perfectly.

After preparing in this way, press the push button switch 55 to
When the motor 20 is started, the rotation of the motor 20 causes the lower brush 22, the lower roller 23, the upper brush 24 and the upper roller via the chains 31, 34 and 33 and the sprockets 27A to 27F and the idler sprockets 28a to 28e as described above. 25, respectively, and these are rotated in a predetermined direction. In this case, the lower roller 23 rotates counterclockwise in FIG.
Rotates in the opposite direction. Therefore, the hose 12 is pulled out from the hose storage box 8 by the rotation of the upper and lower rollers 25 and 23, and each hose winding body 11 rotates while sliding on the hose receiving roller 10. The drawn out hose 12 is washed with the rotating upper and lower brushes 24 and 22 and the washing water sprayed from the nozzle pipe 40, and is discharged through the stand 17. At the time of cleaning, the two hoses 2 can be sent into the apparatus at the same time for cleaning, and therefore the cleaning time can be shortened.

While the hose 12 is being washed and conveyed, the arm 46 of the automatic stop device 45 is rotated by the weight of the stop roller 48 and the switch pressing portion 50 presses the contact 49a of the micro switch 49, so the motor 20 is rotated. It is possible. At this time,
Since the rotation limit of the arm 46 is restricted by the stopper 52, the contact 49a of the micro switch 49 is not pushed too much. When the connector fitting at the end of the hose passes between the stop roller 48 and the guide roller 15, the arm 46 moves to the fifth position.
By rotating counterclockwise in the figure, the switch pressing portion 50 separates from the contact 49a of the micro switch 49, and the motor 20 stops. In this case, even if the arm 46 rapidly rotates, the free end of the arm 46 is away from the contact 49a of the micro switch 49, so that the micro switch 49 is not damaged. When the motor 20 is stopped, the upper cover 5 is opened and the remaining portion of the hose 12 is pulled out of the machine to complete the cleaning work. After the washing is completed, after closing the upper lid 5, the hose storage box 8 is rotated to be stored in the main body 2 as shown by a chain line in FIG. 2, and the stand 17 is folded. Then, the casters 6 are rolled to move and store the hose cleaning device 1 in a corner of a warehouse or the like. At that time, since the hose storage box 8 is stored in the main body 2, the space occupied by the entire device is reduced. It

In the above embodiment, the inside of the hose storage box 8 is divided by the partition member 9
Although the case where the two hose storage chambers A and B are defined by the above, the present invention is not limited to this, and it goes without saying that two or more chambers may be defined as necessary. is there.
