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 reliably winding a fire hose without winding it.

[0002]

2. Description of the Related Art When a fire engine is dispatched once to carry out fire fighting activities, about 40 to 50 hoses are used. The used fire hose is usually stored in a double wound state after being washed and dried in preparation for the next dispatch. That is, the fire hose has a center portion (correctly 1/2 to 45 of the total length) of the male and female mouthpieces provided at both ends of the fire hose so that the male mouthpiece is inside the female mouthpiece when wound up.
It is wound in a double winding from 0 mm (the portion close to the male mouthpiece), but a fire hose having a length of 20 m and made of a braided resin fiber having an inner surface rubberized as described above. Double-rolling requires a considerable amount of work, and is becoming a major problem as the number of firemen increases.

Therefore, various fire hose take-up devices have been provided in which the take-up shaft is rotated manually or electrically to wind it around the take-up shaft.

[0004]

This invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to wind a fire hose evenly with a simple structure and to prevent a protruding portion from the side surface of the device. It is to provide a reduced fire hose winding device.

[0005]

In order to achieve the above-mentioned object, in the present invention, a substantially center of a fire hose is fixed to a winding shaft rotatably supported by a casing, and the winding shaft is rotated. In the fire hose take-up device for taking up the fire hose, the casing has a predetermined angle so as to abut one side of the fire hose taken up by the take-up shaft and align the same side. It is characterized in that it has an inclined guide surface, and that the winding shaft is supported so as to be substantially orthogonal to this guide surface.

[0006]

[Operation] Since the winding shaft is supported so as to be substantially orthogonal to the inclined winding guide surface, the winding guide surface acts as a guide surface on one side of the flattened fire hose, and the fire hose. It is possible to wind while aligning one side surface of one side, and it is possible to wind evenly. Further, it is possible to prevent the bundle of wound fire hoses from collapsing or falling off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, this fire hose winding device has a winding guide surface 1a inclined by a predetermined angle, vertical side surfaces 1b and 1b, and a vertical rear surface 1.
It has a housing 1 having c and 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 speed reducer, and a pair of hoses arranged along a hose winding path leading to the winding drive shaft 3. The guide means 5A and 5B are the winding guide surface 1a.
It is installed so that it stands upright on the surface of. Each hose guide means 5A, 5B has a pair of guide rollers 5a, 5a arranged at a predetermined interval and is elastically in contact with the fire hose 4 between them, and its position is changed by the passage of the hose caps 4a, 4b. It is composed of a detecting roller 5b which is displaced. Further, the end surface of the winding drive shaft 3 projects substantially the same as or slightly protrudes from the surface of the winding guide surface 1a, and a pair of winding pins 3a, 3a are arranged parallel to the end surface in the axial direction. Has been planted in.

According to this winding device, the fire hose 4 is
The hose guide means 5A, 5B are passed in a folded shape, and the winding drive shaft 3 is rotated by hooking the substantially central portion of the hose guide means 5A, 5B to one of the winding pins 3a so that the fire hose 4 is doubled as shown in FIG. It can be a wound body of a roll. In addition,
In order to easily remove the wound hose body after winding, it is preferable to use the winding tool 6 as an attachment. That is, the winding tool 6 is composed of, for example, a circular substrate 7 and a pair of winding cores 8a and 8b that are planted so as to be parallel to each other. The free end side of is removable from the end surface of the winding drive shaft 3. In this example, each core 8
Reference characters a and 8b are hollow shafts fitted to the winding pins 3a and 3a. According to this, the fire hose 4 is provided with each winding core 8 of the winding tool 6.
Although it is wound on a and 8b, the winding tool 6 can be attached and detached even if it is wound considerably tightly. Therefore, the fire hose 4 that has been double wound is removed from the winding drive shaft 3 together with the winding tool 6. Can be easily removed. When the winding drive shaft 3 is detached, the free ends of the winding cores 8a and 8b are attached to the fire hose 4.
The winding tool 6 can be easily separated from the hose 4 because it is slightly bent by the winding pressure (see FIG. 3).

When winding up the fire hose 4, first,
Approximately ½ to 450 mm of the total length of the hose, hang a mark (not shown) on the side of the male base 4a on either one of the winding cores 8a and 8b of the winding tool 6, and attach the winding tool 6 to the same. The winding pins 3a and 3a are fitted together. Then, the hose portion 4c on the male base 4a side is passed through the upper hose guide means 5A, and the hose portion 4d on the female base 4b side is passed through the lower hose guide means 5B. Thereafter, the winding drive shaft 3 is rotated counterclockwise in FIG. 1 (direction of arrow B), that is, the hose portion 4c on the male base 4a side is the inner winding side. As a result, the inner hose portion 4c and the outer hose portion 4d are both detected by the detection rollers 5b of the hose guide means 5A, 5B.
Even if the fire hose is slightly expanded, it will be flattened and loosened by passing through these hose guide means 5A, 5B while being bent in a dogleg shape by 5b. Tighten drive shaft 3 tightly without
Can be rolled up. Inclined winding guide surface 1a
Acts as a guide surface for the side surface of the flattened fire hose 4 and is wound while aligning one side surface of the fire hose 4 so that the fire hose 4 can be wound evenly and at the same time It is possible to prevent the fire hose 4 from falling off.

At the end of the hose, first, the male cap 4a passes through the guide roller 5a on the left side of FIG. 1 of the hose guide means 5A and contacts the next detection roller 5b to displace the roller 5b. This displacement is detected with a micro switch, etc.
Stop the motor 2. Hose part 4 up to male base 4a
Even if there is kinking in c, this kinking applies a force above the set value to the detection roller 5b, the detection roller 5b is displaced, and the motor 2 is similarly stopped. When such kinking occurs in the lower hose portion 4d, it is detected by the detection roller 5b of the lower hose guide means 5B, and the motor 2 is stopped. In these cases, the twist may be corrected and the motor 2 may be restarted.

Unlike the above description, when the hose portion 4c on the male mouthpiece 4a side is passed through the lower hose guide means 5B and the hose portion 4d on the female mouthpiece 4b side is passed through the upper hose guide means 5A, The winding drive shaft 3 may be rotated clockwise in FIG. 1 (counter arrow direction). As a result, the detection roller 5b of the lower hose guide means 5B is connected to the fire hose 4
The motor 2 is stopped by detecting the male base 4a.

[0013]

As described above, according to the present invention, since the winding shaft is supported so as to be substantially orthogonal to the inclined winding guide surface, the fire hose having a flat winding guide surface. Acting as a guide surface on one side of the fire hose, it will be wound while aligning one side of the fire hose,
The fire hose can be wound evenly, and since only one side of the fire hose is guided, it is possible to reliably wind fire hoses of different widths. In addition, since the wound body of the fire hose is also supported diagonally, it is possible to prevent the bundle of wound bodies from collapsing or falling off from the winding guide surface even if some impact is applied. Since it is attached to the inclined winding guide surface, the protruding portion from the side surface of the apparatus can be reduced accordingly.
