Japanese Unexamined Patent Publication No. 2014-105102

The present invention has been made in view of such circumstances, and is a device capable of easily winding and unwinding a hose on a hose reel and easily transporting a hose wound on a hose reel. Is intended to provide.

Thus, the present invention comprises a frame, wheels provided at the lower ends of the frame, a reel support hook rotatably provided at the upper center of the frame, and a front attached to the reel support hook. A traveling frame having a handle for an extended traveling operation, a take-up reel having a pair of wheel frames on both left and right sides, and a winding reel having a larger diameter than the wheel frame and coaxial with the wheel frame on the outside of the wheel frame. It consists of a pair of outer ring frames provided and a reel having a one-way clutch that transmits only the rotation of the outer ring frame in the hose winding direction to the take-up reel. It is characterized in that it is rotatably supported by the reel support hook.

In the present invention, it is preferable to provide a guide roller for guiding the hose at the front end of the handle. Further, in the present invention, the reel support hook has a recess that opens upward and a slope that follows the recess, and the reel rotation shaft is fitted into the recess to rotatably support the reel on the reel support hook. Is preferable.

Right side view of the hose winding device of the present invention Front view of the hose winding device of the present invention Right side view of the state where the reel is lowered from the traveling frame in the present invention.

Hereinafter, the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a traveling frame, and a pair of frames 2 are provided on the left and right sides of the traveling frame, and wheels 3 and 3 are provided at lower front and rear ends of the frame 2.

Further, a reel support hook 4 is rotatably provided in the upper center of the frame 2, and a running operation handle 5 attached to the reel support hook 4 is provided so as to extend forward.

A handle 7 for operating the travel operation handle 5 is provided at the front end of the travel operation handle 5, and a guide roller 6 for guiding a hose is provided between the front ends of the travel operation handle 5. Has been done.

Reference numeral 8 is a reel supported by the reel support hook 4, and in the reel 8, 9 is a take-up reel having a pair of ring frames 10 on the left and right, and the ring frames 10 are on both sides of the ring frame 10. A pair of outer ring frames 11 having a diameter larger than 10 is provided, and the outer ring frame 11 is provided coaxially with the ring frame 10.

Further, a space 18 is formed in the central portion of the take-up reel 9 so that a connection fitting attached to the terminal of the hose 15 can be stored.

The outer ring frame 11 and the take-up reel 9 are connected via a one-way clutch 12, and the one-way clutch 12 winds the rotation only when the outer ring frame 11 is rotated in the hose winding direction. It is designed to be transmitted to 9.

Thus, the rotary shaft 13 projecting from the left and right ends of the reel 8 is locked to the recess 14 formed in the upper part of the reel support hook 4, so that the reel 8 can rotate with respect to the reel support hook 4. It is supported.

Therefore, in the present invention, the rotary shaft 13 of the reel 8 is locked to the recess 14 of the reel support hook 4, the reel 8 is rotatably supported, and the hose 15 is hung on the induction roller 6 and attached to one end thereof. The connection fitting is accommodated in the space 18 of the take-up reel 9, and the hose 15 is wound around the take-up reel 9.

Then, by grasping the outer ring frame 11 and rotating it in the hose winding direction (direction of arrow A in FIG. 1), the winding reel 9 is rotated in the same direction as the outer ring frame 11 by the one-way clutch 12, and the winding reel 9 is used. Wind the hose 15.

At this time, both outer ring frames 11 can be grasped by both hands and rotated at the same time, but by alternately rotating both outer ring frames 11 in the hose winding direction and rotating the outer ring frame 11 on the opposite side in the opposite direction, the outer ring frames 11 can be rotated in the opposite direction. Since the one-way clutch 12 rotates only in the hose winding direction, the hose 15 can be easily wound around the winding reel 9 without having to pick up the hose 15 while holding both outer ring frames 11 with both hands.

By pulling the hose 15 from the reel 8 with the hose 15 wound around the hook metal fitting 9, the hose 15 can be freely drawn out from the reel 8 while rotating the reel 8 in the direction opposite to the A direction. You can also.

Further, after the hose 15 is wound around the take-up reel 9 in this way, the handle 7 can be grasped and the wheels 3 and 3 can be rolled to move to an arbitrary position, and the hose 15 can be wound around the take-up reel 9. The hose 15 can be carried in a rotated state.

Then, when the hose 15 is stored, the handle 7 is lifted there as shown in FIG. 3, and the handle 5 for running operation is rotated clockwise around the rotation shaft 16 of the reel support hook 4. Let me.

As a result, the rotating shaft 13 of the reel 8 is disengaged from the second shaft 14 of the reel support hook 4, the slope 17 is rolled, the outer ring frame 11 comes into contact with the floor surface, and the reel 8 can be lowered from the traveling frame 1. The reel 8 can be rolled and moved, and the traveling frame 1 can be moved to the work of winding the hose 15 around another reel 8.

According to the present invention, the take-up reel 9 is integrally provided with the outer ring frame 11 in the reel 8, and it is not necessary to attach / detach the ratchet lever as in the above-mentioned publication, and the mounting portion thereof is broken or the ratchet lever is lost. There is no fear of ratcheting.

Further, according to the present invention, since the outer ring frame 11 is connected to the take-up reel 9 via the one-way clutch 12, the one-way clutch is obtained by grasping both outer ring frames 11 with both hands and rotating them alternately. Due to the action of 12, the take-up reel 9 rotates only in the take-up direction of the hose 15, and the hose 15 can be easily wound.

Further, according to the present invention, since the reel 8 is composed of a take-up reel 9 for winding the hose 15 and an outer ring frame 11 having a diameter larger than that of the ring frame 10 of the take-up reel 9, the reel 8 is rolled on the ground. Even when the hose 15 wound around the take-up reel 9 is separated from the ground, even if the winding of the hose 15 is slightly loose, the hose 15 may be rubbed against the ground and become dirty or damaged. do not have.
