BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a fire hose, and more particularly to a fire hose winding device for surely winding a fire hose without unevenness.

[0002]

2. Description of the Related Art When a fire truck is dispatched once and a fire fighting operation is performed, approximately 40 to 50 hoses are used. Used fire hoses are washed and dried for the next dispatch and are usually stored in double-wrapped condition. That is, the center of the fire hose (exactly from 1/2 to 45% of the entire length) of the male and female bases provided at both ends of the fire hose at the time of winding up so that the male base comes inside the female base.
It is wound in a double winding form from the part close to the male cap of about 0 mm), but the fire hose having a length of 20 m and made of a resin-fiber braided rubber-coated inner surface is used as described above. Double winding requires considerable effort and is becoming a major problem with the aging of firefighters.

Accordingly, various fire hose winding devices have been provided in which a winding shaft is rotated manually or electrically and wound around the winding shaft.

As an example, as shown in FIGS. 2 to 4, the center of a fire hose is fixed to a winding shaft rotatably supported by a housing, and the winding shaft is rotated to wind the fire hose. The applicant of the present invention has proposed a fire hose winding device and registered it as Utility Model Registration No. 1958559.

More specifically, as shown in FIGS. 2 and 3, the fire hose winding device includes a winding guide surface 1a inclined at a predetermined angle, vertical side surfaces 1b, 1b, and a vertical rear surface. 1c and a housing 1 having a horizontal upper surface 1d. On the winding guide surface 1a, a winding drive shaft 3 rotated at a predetermined rotation speed by a motor 2 with a reduction gear, and a pair of hoses arranged along a hose winding path leading to the winding drive shaft 3. Guide means 5A and 5B are provided so as to stand upright on the winding guide surface 1a. Each hose guide means 5A, 5B has a pair of guide rollers 5a, 5a arranged at a predetermined interval, and elastically contacts the fire hose 4 between them, and passes through the hose bases 4a, 4b shown in FIG. The detection roller 5b whose position is displaced by
Consists of The end surface of the take-up drive shaft 3 is substantially the same as or slightly protrudes from the surface of the take-up guide surface 1a, and a pair of take-up pins 3a are parallel to the end surface along the axial direction. It is planted in. Further, in order to easily remove the hose wound body after winding, a winding tool 6 as an attachment is provided. The winding device 6 includes, for example, a substrate 7 having a circular shape and a pair of core members 8a, 8b erected so as to be parallel to the substrate 7, and each of the core members 8a, 8b. Is constituted by a hollow shaft fitted to the winding pins 3a, 3a.

[0006] When winding up the fire hose 4, first,
A mark (not shown) provided near the male base 4a for about 1/2 to 450 mm of the entire length of the hose is hung on one of the core members 8a and 8b of the winding device 6, and the winding device 6 Is fitted to the winding pins 3a, 3a. Then, the hose portion 4c on the male base 4a side is connected to the upper hose guide means 5A.
Then, the hose portion 4d on the female mouthpiece 4b side is passed through the lower hose guide means 5B. Thereafter, the winding drive shaft 3 is rotated counterclockwise in FIG. 1 (in the direction of arrow B), that is, so that the hose portion 4c on the male base 4a side becomes the inner winding side. Thereby, the inner hose portion 4c and the outer hose portion 4d
Are the respective detection rollers 5 of the hose guide means 5A and 5B.
b and 5b, and are wound on the respective winding cores 8a and 8b of the winding device 6 while being bent in a V-shape.
Is slightly flattened by passing through the hose guide means 5A, 5B, and can be wound tightly on the winding device 6 without loosening. In this way, the fire hose 4 can be formed as a double wound body as shown in FIG. According to this, the fire hose 4 is wound on each of the core members 8a and 8b of the winding device 6, but even if it is wound tightly, the winding device 6 is detachable.
The double wound fire hose 4 can be easily removed from the winding drive shaft 3 together with the winding tool 6. Further, when detached from the winding drive shaft 3, the free end sides of the respective core members 8a and 8b are slightly bent by the winding pressure of the fire hose 4, so that the winding tool 6 can be easily separated from the hose 4.

[0007]

In the structure described above, the winding tool 6 is fitted into the winding drive shaft 3 as it is from the free end side, and is pulled out from the free end side when the winding is completed. However, when pulling out, if it is not pulled out in a direction perpendicular to the winding guide surface 1a, it will not come out smoothly, and if you try to pull it out from a slightly inclined direction, a strong force will be required. Further, the pitch between the core members 8a and 8b was narrowed by the wound fire hose 4, and the resistance at the time of pulling out was large, making it difficult to pull out. Furthermore,
Due to the narrow pitch between the core members 8a and 8b, there is also a disadvantage that it is difficult to remove the fire hose 4 from the winding tool 6 as well.

The present invention has been made in view of such a situation of the prior art, and a purpose thereof is to provide a fire hose winding device which can easily be pulled out even if the winding of the fire hose becomes stronger than expected. Is to provide.

[0009]

In order to achieve the above-mentioned object, the present invention provides a device in which a winding drive shaft rotatably supported by a guide surface provided on one surface of a housing is provided at an interval. In a fire hose winding device having a plurality of winding pins and a winding tool having a cylindrical core member for fitting the winding pins, the winding tool is fitted with the winding pins. A plurality of core members, a base for supporting the other end of each of the core members, support means for supporting at least one core member so as to be swingable with respect to the axis thereof, and this swingably supported member. And a biasing means for constantly biasing the wound core member so as to be substantially perpendicular to the base.

[0010]

With the above construction, the core member, which is swingably supported, is always elastically urged so as to be substantially perpendicular to the base, so that all the core members are generally substantially perpendicular to the base. And can be easily fitted to the winding pin of the winding drive shaft. Also, by winding the fire hose, even when the winding core member is bent due to too strong winding, at least one winding shaft is inclined according to the bending of the winding core when the core member is pulled out. be able to. Accordingly, the core member is relatively parallel when the fire hose is removed from the winding shaft, as well as when the fire hose is removed from the winding tool, so that the frictional force acting between the members becomes small and the fire hose can be easily pulled out.

The base 14 has a first receiving portion 18 on the back surface having a diameter larger than the outer diameter of the flange 16, and a first receiving portion 18 coaxially located at the bottom of the first receiving portion 18 and having a diameter substantially equal to the outer diameter of the flange 16. A second receiving portion 19 is formed, and an inclined surface 21 whose diameter decreases toward the front surface of the base portion 14 is formed at a central portion of the second receiving portion 19, and a mounting member is provided at a front end surface of the base portion 14. A through hole 22 having a diameter larger than the outer diameter of 17 is formed. Correspondingly, the end surface 23 of the flange 16 on the side of the mounting member 17 is also inclined.

A recess 24 is formed at the center of the end face of the flange 16 facing the mounting member 17 side, and one end in the axial direction of a compression coil spring 25 as elastic biasing means is fitted into the recess 24. ing. The first receiving portion 18 includes a fixing member 26.
The fixing member 26 has a recess 27 formed coaxially with the recess 24 on the surface facing the recess 24, and the other end of the compression coil spring 25 in the axial direction is fitted. Have been. By attaching the core member 13 in this manner, when a force is applied to the core member 13, the force is applied to the axis 28 against the elastic biasing force of the compression coil spring 25.
At 0 degree, it can swing in any direction. At this time, the maximum swing angle α is determined by the difference between the relative inclination angles of the inclined surface 21 and the end surface 23 of the flange 16.

On the other hand, the base 31 of the core member 12 located on the upper side in FIG. 1 is fixed to be orthogonal to the base 14 by welding as indicated by reference numeral 32. As a result, one of the two core members 12 and 13 is fixed (non-movable), and the other one is capable of swinging in any direction by 360 degrees with the maximum swing angle α as described above. It will be attached.

When the fire hose 4 is wound by the fire hose winding device shown in FIG. 2 and FIG. 3 using the winding tool 11 having the above-described structure, first, an intermediate portion of the fire hose 4 is removed. After hanging on the core member 12 of the winding tool 11,
The core members 12, 13 of the winding tool 6 are fitted to the winding pins 3a, 3a, respectively. Although the core member 13 is swingable, it is normally supported substantially vertically by the compression coil spring 25 on the base 14, so that the core member 13 can be easily fitted to the winding pins 3a. When the winding of the fire hose 4 is completed and the wound body of the fire hose 4 is removed from the apparatus together with the winding tool 6, or when the fired hose 4 is removed from the pins 3 a of the winding drive shaft 3, the core members 12 and 13 are removed. Does not need to be pulled out exactly in a direction perpendicular to the winding guide surface 1a, and even if it is slightly inclined, the core member 13 swings according to the inclination, so that it can be easily removed. Furthermore, by winding up the fire hose 4, the core members 12, 13 are pulled out even if the winding is too strong and a strong force acts on the core members 12, 13 or a bending force acts on them. Occasionally, the core member 13 can be tilted in the direction in which the bending force acts against the elastic force of the compression coil spring 25, and the resistance at the time of removal can be extremely reduced. Thereby, the operation of removing the core member 11 from the fire hose 4 can be performed very easily.

[0016]

As described above, according to the present invention, the winding device in the fire hose winding device supports a plurality of winding core members to which winding pins are fitted, and the other ends of these winding core members. And a supporting means for supporting at least one core member so as to be swingable with respect to the axis thereof, and a means for constantly elastically biasing the core member supported so as to be substantially orthogonal to the base. Since it is constituted by the biasing means, usually, all the winding core members are positioned so as to be substantially perpendicular to the base thereof, and can be easily fitted to the winding pin of the winding drive shaft. Also,
Even when the winding core is too strong and the core is bent,
At least one winding shaft can be tilted according to the bending of the winding core when the winding core member is pulled out. Therefore, when pulling out the winding core member from the winding shaft, the fire hose must be removed from the winding tool. Also in this case, they are relatively parallel to each other, and the frictional force acting between them is small, so that they can be easily pulled out.
