Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelbarrow type fire hose take-up device for taking up a fire hose after completion of fire extinguishing work.

2. Description of the Related Art Heretofore, as a winding device for a wheelbarrow type fire hose, for example, a "fire hose winding device" proposed in Japanese Utility Model Publication No. 59-88066 has been representative.

In this winding device, an axle is fixed to the lower end of a frame having a substantially inverted U shape, and a wheelbarrow type fire hose in which a moving wheel is attached to an axle end protruding from the outer surface of the frame. It is a winding device. Then, guide rollers rotatably fitted on the axle, support bases individually fixed to the vertical frame portions facing each other with a space wider than the width of the hose, and rotatably and detachably mounted on these support bases. It is equipped with a freely supported winding fitting.

In the winding device having such a structure, the substantially central portion in the longitudinal direction of the fire hose is passed under the guide roller and then hung on either one of the pair of pins of the winding fitting. Then, by rotating the handle of the winding fitting while pushing the frame forward, the fire hose is double wound on the winding fitting. Further, the wound hose is removed from the frame together with the winding fitting supported by the support base.

[0004]

The conventional winding device has the following problems.
It is considered that the labor was considerably reduced compared to the manual work of rolling the fire hose after rolling the fire hose on the ground or the floor surface, but some problems remain in practical use. Has been done. That is, the position of the winding metal fitting supported by the frame is higher than the ground or floor surface, and the center of gravity of the device is high, resulting in poor running stability. Moreover, the wound hose is removed from the frame together with the winding metal fitting, so that the workability is poor.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a winding device for a fire hose, which makes the winding operation extremely simple.

[0006]

In order to achieve such an object, the present applicant has proposed a fire hose take-up device, a frame having a substantially inverted U-shape having a hand-pushing handle portion, and this frame. Axle fixed to the lower end of the wheel, moving wheels attached to both ends of this axle, and one of the vertical frames extending in parallel at the interval of the frame, in the longitudinal direction. The structure is provided with a winding handle and a winding metal fitting that are individually pivoted at a distance from each other, and an interlocking member that connects the winding handle and the winding metal fitting.

With such a structure, since the winding fitting is formed below the frame, the center of gravity of the device is lowered,
Driving stability is improved. Further, in the fire hose take-up device having such a structure, the frame is composed of at least two members, and at least one of the pair of vertical frames extending in parallel at intervals is
By using a structure that is pivotally attached to the axle, a pair of vertical frames can be configured as a meandering prevention guide for the hose that is wound up, and the wound hose can be removed from the winding metal fitting without removing the winding metal fitting from the frame. Can be removed,
The workability of the winding work is improved.

[0008]

[Operation] The winding device for a fire hose uses the winding metal fittings by either hanging the approximately central portion of the hose in the longitudinal direction on the winding fitting or by fitting the hose base and turning the winding handle while pushing the frame forward. Wrap the hose around. The wound hose is removed from the winding fitting after moving one of the vertical frames around the axle.

1 and 2 show a winding device for a fire hose which is an embodiment of the present invention. FIG. 1 is a front view and FIG. 2 is a side view. A detailed description will be given below with reference to these drawings. The take-up device 1 for a fire hose includes a first vertical frame 3 extending downward from one end of a hand-pushing handle portion 2 composed of a horizontal frame, and a first vertical frame 3 extending downward from the other end of the hand-pushing handle portion 2. It has a frame composed of a bent portion 4 provided in a protruding manner. A hinge plate 5 having a U-shaped cross section is fixed to or welded to the bent portion 4 with a screw.
A hinge pin 6 is fixed to the. Then, the second vertical frame 7 having a groove (not shown) which can be engaged with and disengaged from the hinge pin 6 extends in parallel with the first vertical frame 3 with a space wider than the width of the fire hose 8. The hand-pushing handle portion 2 and the first and second vertical frames 3 and 7 constitute a frame having a substantially inverted U-shape.

An axle 9 is installed on the lower ends of the pair of vertical frames 3 and 7, and only the vertical frame 7 is rotatably attached to the axle 9. Wheels 1 for movement are provided at both ends of the axle 9.
0 is installed, and the axle 9 between the pair of vertical frames 3 and 7
A guide roller 11 is rotatably fitted on the upper side.

Supports 12 and 13 are fixed to the upper part of the first vertical frame 3 and substantially centrally in the longitudinal direction, and a sprocket 14 and a winding handle 15 are pivotally mounted on the support 12. On the support base 13, a winding fitting 17 and a sprocket 18 in which a pair of pins 16 are protruded at intervals are pivotally mounted. Then, a chain 19 is stretched around the sprockets 14 and 18, and these sprockets 14 and 1 are stretched.
A cover 20 for covering the interlocking member composed of 8 and the chain 19.
However, they are fixed by screws or welded to the support bases 12 and 13 and the vertical frame 3. Reference numeral 21 is a damper rubber that absorbs a shock when the second vertical frame 7 is detached from the hinge pin 6 and tilted, and reference numeral 22 is a rubber foot portion for holding the apparatus 1 upright. .

In the fire hose take-up device 1 having such a structure, the fire hose take-up device 1 passes under the guide roller 11 and then the center of the fire hose 8 in the longitudinal direction, or the cap of the fire hose 8 is taken up by the take-up metal fitting 17. The fire hose 8 is wound around the winding fitting 17 by hooking it on the pin 16 and rotating the winding handle 15 while pushing the winding device 1 forward. At this time, the fire hose 8 meanders, but the pair of vertical frames 3.7 prevents the meandering.

The fire hose 8 wound around the winding fitting 17 is released from the hinge connection between the second vertical frame 7 and the bent portion 4, and the winding device 1 is unfolded. 17
Removed from. Although the interlocking member is composed of the sprockets 14 and 18 and the chain 19 in the above description, the interlocking member is not limited to this. For example, it may be an interlocking member that constitutes a gear such as a miter gear. Also,
The connection between the second vertical frame 7 and the bent portion 4 is not limited to the hinge connection.

[0014]

INDUSTRIAL APPLICABILITY As described above, in the winding device for a fire hose of the present invention, one of the vertical frames extending in parallel at intervals is provided with an interval in the longitudinal direction. Since the winding handle and the winding metal fitting that are pivotally connected to each other are configured and the winding handle and the winding metal fitting are connected by the interlocking member, the winding metal fitting is configured below the frame, and the center of gravity of the device is lowered. , Driving stability is improved. In addition, the frame is composed of two members, and at least one of the vertical frames is pivotally attached to the axle so that the winding device is deployed and then the wound fire hose is removed from the winding fitting. Therefore, not only can the pair of vertical frames be configured as a meandering prevention guide for the fire hose, but the workability of the winding operation can be improved.
