Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a hose reel, and in particular to a hose reel that can be mounted on a vehicle and used effectively. This invention relates to improvements to hose reels that can change the

(Prior Art and its Problems) A so-called hose reel, in which a hose is wound around a cylindrical drum, has been effectively used in various forms such as portable, stationary, and vehicle-mounted. However, conventional hose reels have extremely limited allowable angles when the hose is slanted to the winding direction, and the hose must be aligned manually by moving the hose or hose guide when winding. As a result, the work required extra labor and was sometimes accompanied by dangers such as hands getting caught. In order to solve these deficiencies, an apparatus has been proposed in which the hose reel is configured to be rotatable with respect to a member such as a base so that the hose can be wound in a straight direction in all directions. For example, Jikko 55-
36454, Utsuko 40-25969, etc. However, in the above-mentioned prior art, there are problems in that controlling the turning angle is difficult and complicated, and under certain installation conditions, for example, when mounted on a vehicle, it is difficult to control the turning angle. It had the drawback of not being able to adequately handle three directions.

In order to overcome these drawbacks, the applicant of the present application has already filed an application for an improved hose reel structure. These are Jitsugan No. 58-86657 and Jitsugan Sho.
No. 58-86658. However, in the above-mentioned prior application, for example, when a hose reel is mounted on a car and used, it is installed in a position inside so that it does not become an obstacle to opening and closing the door of the car's cargo bed. In such cases, the hose unwound from the hose reel may come into contact with the edge of the loading platform, damaging the hose. In order to avoid the above-mentioned damage, guide rollers are installed on the edges of the vehicle's loading platform, but the guide rollers that protrude from the vehicle body have to be pulled out from the vehicle body when using a hose and then put back into the vehicle body when the work is finished. was working.

(Purpose of the invention) The present invention solves the above-mentioned conventional deficiencies and provides a device that can effectively work in all directions, thereby reducing worker fatigue and ensuring safety, thereby increasing work efficiency. The aim is to improve the

Reference numeral 18 denotes a lower plate, which has a rotating wheel 19 fixed to its lower surface, and a rotating sprocket 16 fixedly fixed between it and the upper plate 17 on its upper surface. A plurality of sets of support rollers 20, 20 are provided protrudingly provided on the rail 21, and a plurality of swing rollers 22 are suspended and fixed in contact with the outer periphery of the swing rail 21. A swing motor 12 is fixed to the swing drive bracket 11 and has a swing drive sprocket 14 fixed thereto, and the swing drive sprocket 14 and the swing sprocket 16 are connected by a swing chain 15. 23
is a vehicle such as a high-pressure washing vehicle. Reference numeral 25 denotes a moving drive bracket extending from the base 1, to which a moving motor 26 is attached. 27 is a pinion gear fixed to the moving motor 26. Reference numeral 28 denotes a movable wheel bracket extending on the lower surface of the base 1, and a movable wheel 29 is provided near the four corners of the base 1.
is rotatably locked. Reference numeral 30 denotes a moving rail, which is formed into a frame shape by a connecting member 31 to support the moving wheel 29, and has both ends of a rack 32, which is extended near the central portion, locked to the connecting member 31. . The rack 32 is connected to the pinion gear 27.
is engaged with. 33, 33 is the upper plate 17
The rails are fixed to the rails and are arranged parallel to each other. 34 is a movable wheel that is locked to the leg member 2 and engaged with the rail 33. Reference numeral 35 denotes a drive motor, which is engaged with a bracket 36 fixed to the upper plate 17 to drive the upper plate 17.
One end of a feed screw 38 whose other end is supported by a bearing member 37 fixed to is connected. Numeral 39 is a nut fixed to the leg member 2 and engaged with the feed screw 38.

In the device configured in this manner, it is effective that the moving rail 30 is appropriately locked to a conveyance means, and can be mounted on a vehicle or the like. Now, if the initially set direction of the hose reel, that is, the extension line of the hose 10 wound around the reel drum 9, matches the direction of the working position, the hose reel can be attached to the leg member 2 via the rotation drive bracket 3. The rotary drive sprocket 6 is rotated in the rewinding direction by a rotary drive means such as a rotary motor 4, and the reel drum 9 is rotated in the rewinding direction together with the rotary sprocket 8 via the rotary chain 7.
Pay out hose 10 from. Here, if the installed position or direction of the device is different from the actual working position or direction, it is adjusted as necessary.
First, the swing drive sprocket 14 is rotated in a predetermined direction by a swing drive means such as a swing motor 12 attached to the base 1 via the swing drive bracket 11, and the swing sprocket 1 is rotated through the swing chain 15.
Rotate 6. The swing sprocket 16 is clamped and fixed between an upper plate 17 and a lower plate 18, and a reel drum 9 rotatably supported on the leg member 2 is mounted on the upper plate 17, and is fixed below the lower plate 18. Support rollers 20, 20 locked to the rotating wheel 19 sandwich the turning rail 21 and support the members on the lower plate 18,
Rotating roller 2 suspended and fixed from the lower plate 18
2 is configured so as to be in contact with the outer periphery of the turning rail 21 so as to be able to turn smoothly. It is effective for the swing motor 12 to be a reversible motor, but if it is not a reversible motor, the same effect can be achieved by adding a mechanism for mechanically switching the rotation using gears or the like. In this way, the base 1, the swing rail 21 fixed to the base 1, the swing drive bracket 11 and the swing motor 12 fixed to the base 1
Otherwise, it will rotate in a predetermined direction on the base 1. After turning by a predetermined angle, the turning motor 12 is stopped and the reel drum 9 is oriented in a desired direction. Next, when the moving motor 26 is rotated, the pinion gear 27 is rotated by the moving motor 26.
The entire member mounted on the base 1 moves along the rack 32 engaged with the pinion gear 27.
The base 1 has a moving wheel 29 with respect to the moving rail 30.
Since the movable wheel 29 is secured to the base 1 via the movable wheel bracket 28, it can be moved extremely easily and lightly. It is effective for the moving motor 26 to be a reversible motor, but if it is not a reversible motor, the same effect can be achieved by adding a mechanism for mechanically switching the rotation using gears or the like, similar to the swing motor 12. It is possible to achieve the following. Needless to say, the moving operation can take any position within the section defined by the moving rail 30 and the connecting member 31. After moving to the predetermined position, the moving motor 26 is stopped and the hose reel is placed at the predetermined position. The turning operation and the moving operation may be performed in any order, and should be applied in the most effective order depending on the usage situation. In this manner, the operation of feeding out the hose 10 is performed according to the above-described procedure. A reversible motor can be used as the rotary motor 4, and it is effective if the rotation is switched between feeding and winding. When the hose 10 is fed out, the reel drum 9
It is not necessarily necessary to forcibly rotate the reel drum 9, for example, a clutch or the like may be installed between the rotary motor 4 and the rotary drive sprocket 6 so that the reel drum 9 will idle when the hose 10 is pulled by human power or the like. Effective operation can be achieved by providing engagement/disengagement means and rotation control means such as a brake. When the work is completed, the hose 10 will be wound up. The hose 10 is wound up in the following steps. If the work position changes during work, the first hose 10
The unwinding position or direction of the hose 10 is different from the work end position, and therefore the winding direction of the hose 10 may not match the position of the hose 10. To efficiently wind a hose 10 around the reel drum 9 by making the direction coincide with the winding position and direction of the reel drum 9, and then rotating a rotary drive means such as a rotary motor 4 to rotate the reel drum 9. Can be done. When winding up the hose 10, the reel drum 9 has a predetermined width, and as the hose 10 is wound up one after another, the direction in which the hose 10 extends and the winding direction become misaligned, which impedes alignment and winding of the hose 10. However, by using a suitable combination of the moving operation and the turning operation, and moving or turning by a minute position or angle depending on the winding position, it becomes possible to effectively align and wind. Even in cases other than the above, the moving operation, the turning operation, and the rotating operation of the reel drum 9 can be appropriately combined and used effectively. Upper plate 17
Regarding the movement of the leg member 2, it is a movement means that can be used auxiliary in addition to the above-mentioned turning and movement. For example, when the movement rail 30 cannot secure a sufficient length due to installation space or other constraints. It can be effectively used in cases where the device is installed in a location where the device cannot fully function due to various restrictions. In other words, if moving along the moving rail 30 is considered lateral movement, and moving in a direction perpendicular to the moving rail 30 is considered vertical movement, then the hose reel set at a desired position by lateral movement is By further rotating the drive motor 35, the feed screw 38 connected to the drive motor 35 is rotated, and the nut 39 engaged with the feed screw 38 is moved vertically along the feed screw 38. . Natsu 39
is fixed to the leg member 2, so that the leg member 2 can be moved vertically along the rail 33 with respect to the upper plate 17 as the nut 39 is moved vertically. Therefore, the reel drum 9, which is normally disposed approximately in the center of the upper plate 17, is moved closer to the moving rail 30 by the vertical movement together with the leg member 2, making it easier to pay out and wind up the hose 10. It is something that makes you familiar. When the reel drum 9 is rotated by the turning operation and the extending direction of the hose 10 is the same as the extending direction of the moving rail 30, the hose reel set on the connecting member 31 side by lateral movement is moved in the same manner as described above. The leg member 2 can be moved laterally along the rail 33 by rotating the drive motor 35 to move it closer to the connecting member 31 side. Similarly, it will be obvious that even when the reel drum 9 is disposed at a predetermined angle with respect to the moving rail 30, it can be moved diagonally by the same action as described above. It is effective that the drive motor 35 is a reversible motor, but similarly to the swing motor 12 and the movement motor 26, it is also possible to add means for switching the rotation direction by mechanical means. Rotating motor 4, swing motor 12, moving motor 26 and drive motor 3 described in this embodiment
5, a fluid pressure motor such as a pneumatic motor or a hydraulic motor can be effectively used as a reversible motor, and an electric motor or a manual handle can also be used as a driving means, and these driving means can be used in combination. is also possible.

(Effects of the invention) As described in detail above, according to the invention, the position and direction of the hose reel can be changed steplessly and continuously. This can be done by changing the position and direction at the location where it was initially installed, making work more efficient and eliminating the need to change the location of the hose reel or move the hose manually during work. Work can be carried out safely because there are no In particular, when using the present invention mounted on a vehicle such as a high-pressure washing vehicle, for example, when the installation location of the vehicle is limited and the work position spans multiple directions, it is possible to handle the situation without changing the direction of the vehicle. It can be used very effectively.

In addition, by reciprocating the hose reel on the upper plate, it can be moved to the end of the vehicle's loading platform, eliminating the possibility of the hose being damaged by contacting or sliding against the edge of the loading platform. This can extend the life of the hose and prevent work-related accidents due to damage to the hose.
