DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a hose cleaning apparatus for cleaning while traveling hose such as for fire within the enclosure.

[0002]

2. Description of the Related Art Fire hoses used for fire fighting are
Conventionally, this was manually cleaned because it was contaminated with mud and oil.However, the work was done by brushing the wound surface or piled-up hose with a brush to prevent twisting. Was a very laborious and time-consuming task. So, for example,
An electric hose cleaning apparatus as disclosed in Japanese Patent No. 5633 has been proposed. This hose cleaning device includes a pair of hose support rollers arranged side by side in close proximity to the inlet side of the housing, and a pair of upper and lower circular members located behind the hose support rollers and rotating with their hair tips crossing each other. Brush and
A pair of upper and lower rubber rollers are provided at the rear of the brush and rotate with their peripheral surfaces in contact with each other, and an injection nozzle for washing water is provided in front of the brush.

[0003] With such a construction, when washing the hose, the hose winding is placed on a supporting roller, and a hose having a mouthpiece at its tip is pulled out from the hose winding. Is guided by the upper and lower rubber rollers to the outlet of the housing, and the base is suspended from the outlet of the housing to the outside. After preparing in this way, when the motor is started, the hose that is sent out by the rubber roller and discharged from the outlet of the housing is made up of the upper and lower brushes that rotate so that the outer circumference rotates in the direction opposite to the running of the hose, and the nozzle It is washed with the flushing water. In addition, a link mechanism is provided between the brush and the housing outlet, and when the base at the end of the hose passes over the pedestal of the link mechanism and rides on this, the upper rubber roller is moved to the lower side. Since the hose rises so as to be separated from the rubber roller, the hose is pulled out from the outlet of the housing, so that the rubber roller is passed through the base without being damaged, thereby completing the cleaning operation.

[0004]

However, in such a conventional hose cleaning apparatus, as described above, the upper and lower brushes in which the base attached to the unwinding end of the hose circulates in the direction opposite to the running direction. The brush drive motor becomes extremely heavy at that time, and the brush must have a certain degree of hardness to clean the hose. It is difficult to improve the cleaning effect without performing the design, and it is considered that practical application is difficult.

Further, as described above, since the base at the end of the hose is placed on the receiving base of the link mechanism to separate the upper and lower rubber rollers, if the distance between the receiving base and the rubber roller is short, the rubber roller is separated. Before the base passes through the rubber roller, the base may come into contact with the rubber roller, damaging the rubber roller or causing a serious accident, resulting in a lack of reliability. When the interval is long, there is a problem that the entire device becomes large. Further, if the hose is not pulled out from the outlet, the hose fed by the rubber roller may not be discharged smoothly, and there is a problem that a satisfactory cleaning function cannot be expected.

Further, since the brush orbits in the direction opposite to that of the rubber roller, the load on the brush side increases during the transfer of the hose, causing slippage of the belt and slack of the chain, which results in insufficient cleaning. There's a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a hose cleaning apparatus capable of reliably cleaning a hose without providing a rotating brush.

[0008]

According to the present invention, a high-pressure washing liquid jet nozzle is supported in a hose transfer path of upper and lower feed rollers for transferring a hose in a housing, and a feed roller is provided. A guide member that is inclined so as to become lower toward the hose discharge port of the housing is supported on the downstream side in the hose transfer direction, and the hose base detection plate is positioned upstream of the feed roller in the hose transfer direction. It was supported by the upper lid of the body.

[0009]

[Function] To clean the hose, place the hose unwound from the hose winding body on the lower feed roller with the upper lid open, and let the base at the hose start end be supported by the guide member. When the motor and pump are started with the valve closed, the hose base slides down on the guide member and the hose is transported by the upper and lower feed rollers. The hose can be cleaned well without it. When the base at the end of the unwinding hose comes into contact with the detection plate, the limit switch connected to the detection plate opens and stops the motor, so the upper lid is opened, released from being pinched by the upper and lower rollers, and left in the housing. The cleaning operation is completed by removing some of the hoses outside the housing.
