Description

Foldable Fire Hose Winding Device

The present invention relates to a fire hose winding device, and more particularly, to a folding fire hose winding device that is easy to carry and lightweight.

In general, a fire hose recovery device is a device for winding up a fire hose having a length of several meters or more for fire suppression so that it is easy to use. Conventionally, there is no means for properly winding a fire hose in a fire fighting vehicle or a fire station, so the long fire hose must be rolled from the beginning to the end to be arranged. is becoming In addition, the rolled up fire hose was disturbed during transportation, which was a delay factor in the firefighting operation.

Therefore, in the prior art, a number of fire hose winding devices are known to wind the fire hose on a rotating drum, etc., so that it can be used conveniently. However, the conventional fire hose winding device has a disadvantage in that the weight is heavy and thus portability is deteriorated.

On the other hand, FIG. 1 is a state diagram of a conventional fire hose recovery device in use, FIG. 2 is a state diagram showing the use of the fire hose recovery device shown in FIG. 1 step by step, and FIG. 3 is a plate assembly 200 shown in FIG. is a perspective view. 1, 2, 3, the conventional fire hose recovery device 5 connects the shaft assembly 100 to the chuck 11 of a power tool 10 such as a portable electric drill, and the shaft assembly ( 100) is fixed by hanging one end of the fire hose 30. Then, when the power tool 10 is rotated, the fire hose 30 is wound while the second shaft 120 turns around the first shaft 110 . At this time, the fire hose 30 to be wound appears in the form of a gradually increasing radius on the rotating plate 210 .

However, such a conventional fire hose recovery device has the following problems. First, since the rotating plate 210 is a heavy metal product, it is inconvenient to carry and handle, and there is a disadvantage in that the manufacturing cost is increased. And, there was a fear of causing a back injury of the operator when placed on the floor for use.

In addition, the conventional fire hose recovery device is not easy to transport and store because the rotating plate 210 is large, occupies a lot of space when mounted on a fire engine, and personal portability is impossible.

In addition, as the amount of winding of the fire hose increases, the weight increases, and thus there is a problem in that the wound fire hose and the rotating plate 210 rotate together.

configuration of the embodiment

Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the accompanying drawings. 4 is a perspective view of a folding fire hose winding device in an unfolded state according to an embodiment of the present invention. As shown in FIG. 4 , the central portion 530 has a disk shape that can be fixed to the floor, and includes a bearing therein. The center 530 may be made of a metal material or a synthetic resin material.

The rotating body 510 is rotatably assembled on the upper surface of the central part 530 and is rotationally supported by a bearing. The rotating body 510 has a metal disk shape, and a shaft fixing groove 520 is formed in the center of the upper surface. An auxiliary fixing hole for the second shaft 120 may be further formed around the shaft fixing groove 520 .

The joint 540 is a component such as a hinge or a hinge, and is assembled with a bolt and a nut. Three joints 540 are provided at equal intervals of 120 degrees on the circumferential side of the central portion 530 . 6 can be used as required. The joint 540 allows the support to rotate in the range of 0 to 90°.

One end of the first support 550 is connected to the joint 540, and the other end is a length member forming a free end. The fire hose 30 may be wound by a radius corresponding to the length of the first support 550 . The free end of the first supporter 550 may be fixed to prevent rotation by the operator stepping on it.

One end of the second support 560 is connected to the joint 540, and the other end is a length member forming a free end. The length of the second support 560 is the same as that of the first support 550 . A second roller 590 is installed at the free end of the second support 560 . The second roller 590 is in close contact with the side of the wound fire hose and serves to guide the rotation. To this end, when the second support 560 is in an unfolded state, the second roller 590 is formed perpendicular to the second support 560 to form an axial direction parallel to the shaft. The second roller 590 is a pair of second rollers 590 positioned adjacently.

One end of the third support 570 is connected to the joint 540, and the other end is a length member forming a free end. The length of the third support 570 is the same as that of the first and second supports 550 and 560 . A first roller 580 is installed at the free end of the third support 570 . The size and function of the first roller 590 are the same as those of the second roller 590 . The first roller 580 is a pair of first rollers 580 positioned adjacently.

6 is a perspective view of the folding fire hose winding device shown in FIG. 4 in a folded state. As shown in FIG. 6 , the first, second, and third supports 550 , 560 , and 570 may be folded toward the center 530 . At this time, the first and second rollers 580 and 590 almost come into contact without causing mutual interference due to a slight difference in position.

7 is a perspective view of the shaft assembly 100 . As shown in FIG. 7 , the connecting shaft 140 is positioned on the upper surface of the connecting part 130 , and the first and second shafts 110 and 120 are configured on the lower surface of the connecting part 130 . The connecting shaft 140 is relatively short in length, passes through the center of the connecting portion 130 and is connected to the chuck 11 of the power tool 10 .

The first shaft 110 may be integral with the connecting shaft 140 , and form the same axis as the connecting shaft 140 . An end of the first shaft 110 may be fitted into the shaft fixing groove 520 .

The second shaft 120 is parallel to the first shaft 110 and has a shorter length than the first shaft 110 . One end or an intermediate region of the fire hose 30 is inserted into an interval between the first and second shafts 110 and 120 to complete the initial setting state for winding.

operation of the embodiment

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the accompanying drawings. Figure 5 is a state diagram of the use of the fire hose winding device shown in Figure 4; As shown in FIG. 5 , first, a worker (eg, a firefighter) spreads the fire hose recovery device 500 in a folded state as shown in FIG. 6 on a flat floor.

Next, after assembling the connecting shaft 140 to the chuck 11 of the power tool 10 , the first shaft 110 is inserted into the shaft fixing groove 520 .

Then, one end of the fire hose 30 is inserted between the first and second shafts 110 and 120 .

Then, when the operator steps on the first support 550 with one foot and rotates the power tool 10, the radius increases while the fire hose 30 starts to be wound. When the radius increases to the maximum and comes into contact with the first and second rollers 580 and 590, the rotation is stopped and the treble of the wound fire hose is taken out. By repeating such an operation, a plurality of fire hoses can be quickly wound, stored, and moved.

The used fire hose recovery device 500 stores or moves the first, second, and third supports 550, 560, and 570 by folding as shown in FIG.
