  Since the reel for movable long objects of the present invention is configured as described above, according to this, it is possible to easily take up and pull out hoses and other long objects. In addition, the winding amount can be easily adjusted. Furthermore, deformation and aging of a long object such as a hose can be effectively prevented.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory view of a main part of a movable long object reel according to the present invention in a side view, and shows a state in which a gantry is grounded. That is, it represents a state in which the apparatus is stopped, and shows a state when a long object is used or stored. Also,
FIG. 2 is an explanatory view in a side view showing a state where the movable arm reel of FIG. 1 is prepared to move by swinging the gripping arm rod forward. That is, the state at the time of movement of this apparatus is shown.

  As shown in the drawings, the movable long object reel of the present invention has a basic configuration in which a reel part is provided on a carriage part, and the reel part is used to wind up a hose, a cord and other long objects. It comprises a winding drum 8 and a passive wheel 2 fixed coaxially to the winding drum 8 on the outer side, while the carriage part is continuous with the frame 3 provided with wheels 1 and the frame 3. A holding arm rod 4 comprising a holding arm rod 6 provided on which a shaft 7 of the reel portion is pivoted is pivoted on the frame 3 so as to be swingable in the longitudinal direction of the reel for the movable long object. The main configuration is that the passive wheel 2 and the wheel 1 are arranged so as to be in contact with each other at one end of the swing range.

  Further, in the movable long reel, the wheel 1 is closer to the gripping arm rod 6 than the bearing arm rod 4 (hereinafter, the direction toward the gripping arm rod 6 is referred to as the front side). ), The passive arm 2 is brought into contact with the wheel 1 by tilting the grip arm arm 6 forward and swinging the bearing arm arm 4 forward. The passive wheel 2 is configured to be able to be transmitted.

  With this configuration, in this movable reel for long objects, by tilting the gripping arm rod 6 forward, the bearing arm rod 4 swings forward, at the front end of the swing range. The rotation of the wheel 1 is transmitted to the passive wheel 2 because the passive wheel 2 of the reel unit comes into contact with the wheel 1 by stopping. The rotation transmitted to the passive wheel 2 becomes the rotation of the take-up drum 8 as it is, and the hose, cord and other long objects set on the take-up drum 8 are wound around the take-up drum 8 depending on the direction of rotation. Is unwound and pulled out.

  On the other hand, when the gripping arm rod 6 is tilted rearward, the bearing arm rod 4 swings rearward and stops at the rear end of the swinging range. Since the passive wheel 2 is completely separated from the wheel 1, the rotation of the wheel 1 is not transmitted to the passive wheel 2. Therefore, regardless of the rotation of the wheel 1, that is, the movement of the carriage, the rotation of the wheel 1 is not transmitted to the reel portion, and the hose, cord and other long lengths set on the winding drum 8 are not transmitted. The object is not taken up by the take-up drum 8 by the movement of the carriage, and is not unwound and pulled out.

  Further, when the bearing arm rod 4 is swung forward and positioned at the front end of the swinging range, the inclination of the gripping arm rod 6 is moved or moved up and down. It is also possible to increase or decrease the contact pressure between the wheel 1 and the passive wheel 2, whereby the degree of contact of the passive wheel 2 with the wheel 1 is controlled, and the rotation of the wheel 1 to the passive wheel 2 is controlled. Since the amount of transmission is controlled, the pitch of the long object to be wound around the take-up drum 8 is adjusted, so that it is possible to prevent the long object from being excessively wound and to be wound / drawn with a constant winding pressure.

  In other words, the movable long reel according to the present invention controls the intermittent movement of the passive wheel 2 and the wheel 1 connected thereto by swinging the bearing arm rod 4 to move the carriage. And the interlocking of the reel unit rotation.

  As shown in FIGS. 1 and 2, in addition to the basic configuration described above, the movable long reel has a bearing arm 5 with a restraining tool 5 for restraining the swinging of the bearing arm 4 from the rear. It can be an attached configuration. As a result, the bearing arm rod 4 is prevented from swinging backward regardless of whether it is moving or stopped, and the operation of the above-described apparatus is stably maintained.

  In addition, the restraining tool 5 is configured to be attached to the carriage part as having at least a rail structure 51 closed at the rear end, and the bearing arm rod 4 is provided with a sliding member, The sliding member can be configured to slide on the rail structure 51. With such a configuration, the swinging of the bearing arm rod 4 is smoothly performed by sliding in the rail structure 51, and the backward swinging is effectively prevented. Although the sliding member is not shown in each drawing, it can be provided as a horizontal casing erected on the upper part of the bearing arm rod 4 provided with the reel portion interposed therebetween (note that it will be described later) (See 3 etc.).

FIG. 2-2A is an explanatory view in side view showing the configuration of the main part of another example of the movable long reel of the present invention, and is a diagram showing a state in which the gantry is grounded. That is, it represents a state in which the apparatus is stopped, and shows a state when a long object is used or stored. Also,
FIG. 2-2B is an explanatory view in a side view showing a state in which the movable arm reel of FIG. 2-2A is prepared to move by swinging the gripping arm rod forward. That is, the state at the time of movement of this apparatus is shown. As shown in these drawings, the movable long reel has a structure in which a locking portion capable of locking the bearing arm rod 14 is provided at the rear side end of the locking device 15. Can do.

  In the state of FIG. 2-2A, the sliding member of the bearing arm rod 14 is reversibly locked to the locking portion provided at the rear end portion of the rail structure 151. The sliding member does not move freely on the rail structure 151 and can maintain a stable fixed state. The locking in the locking structure can be easily released if intended.

  Although not shown in the drawings, the bearing arm rod 14 can be moved while being locked to the rear end portion even when the apparatus is moved. The state where the wheel 11 and the passive wheel 12 are transmitted can be released.

FIG. 3 is a perspective explanatory view showing an example in which the movable long object reel of the present invention is configured as a hose reel for flooding. Also,
FIG. 4 is an explanatory view showing a state where the hose is set in the example of FIG. As shown in these figures, at least one of the wheel 21 and the passive wheel 22 has a concavo-convex structure or meshing structure S1, S2 on its surface in order to prevent or suppress transmission loss between both the wheels 21, 22. It can be set as the provided structure. With this configuration, the stability of transmission control between the wheel 21 and the passive wheel 22 can be enhanced.

  The wheel 21 and the take-up drum 28 may constitute an axial ratio or a transmission structure of the wheel 21, the passive wheel 22 and the take-up drum 28 so that their rotational distances are equal. it can.

The hose reel embodiment of the present invention shown in FIGS. 3 and 4 will be further described.
As shown in these figures, in this example, the hose reel (winding drum 28) can be rotated by utilizing the rotation of the wheel 21 of the carriage, and the winding or drawing of the hose H can be performed with the wheel 21 of the carriage and the hose reel. This can be done without touching the hose using the contact pressure interlocking with the passive wheel 22.

  That is, the configuration of this example is characterized in that the passive wheel 22 is provided outside the flange of the hose reel and is integrated with the hose reel so that the wheel 21 and the passive wheel 22 are in contact with each other. Then, the hose reel (or its center of gravity; hereinafter simply referred to as “hose reel”) is moved by tilting the gripping arm rod 26 having the handle portion of the carriage or moving it in the vertical direction. It moves between the tip of the gantry 23 and the wheel 21 to enable the hose H to be wound and pulled out by a stable stop state of the cart and movement of the cart.

  Also, the contact pressure between the wheel 21 and the passive wheel 22 can be increased or decreased by the vertical movement of the handle (grip arm rod 26), and the hose H can be wound with a constant winding pressure.

The operation of this example hose reel will be described in detail with reference to FIGS. 3 and 4 and with reference to FIGS.
As shown in FIG. 1, when the hose reel of this example is stopped, such as during flooding work or storage, the bearing arm rod 24 and the shaft portion 27 swing around the fulcrum 24C on the pedestal 23. Since the reel portion (winding drum 28) automatically moves to the rear end side of the gantry 23, the wheel 21 and the passive wheel 22 are separated from each other, and at the same time, the bearing arm rod 24 is moved by the restraining device 25. It is automatically stopped. The wheel 21 and the passive wheel 22 are not linked to each other. Of course, the entire hose reel can be moved in this state.

  Even if the carriage is moved from this stopped state, since the bearing arm rod 24 of the reel portion is restrained by the restraining tool 25, the wheel 21 and the passive wheel 22 remain separated. Therefore, the reel portion does not rotate in conjunction with the hose H, so that the entire hose reel can be moved. For example, when the hose H is attached to a faucet or the like in this state, it is of course possible to pull out the hose H by moving the carriage.

  As described in FIG. 2, when moving, the bearing arm rod 24 slides on the rail structure 251 of the restraining tool 25 and is positioned at the front end, and the wheel 21 and the passive wheel 22 are in contact with each other and interlocked with each other. It becomes. As the carriage moves, the wheel 21 and the passive wheel 22 rotate in conjunction with each other, rotate the reel portion (winding drum 28), and wind up and pull out the hose H.

  When the hose H is excessively wound due to the movement, the reel portion is pulled by the hose H, so that the wheel 21 and the passive wheel 22 are separated from each other, and the contact pressure friction is reduced, so that the winding is stopped or the degree is temporarily weakened. Further, the winding is started again by the further movement, but such winding and drawing adjustment are automatically performed. In addition, the pitch and degree of winding can be controlled by increasing / decreasing the contact pressure between the wheel 21 and the passive wheel 22 by the vertical movement of the handle, preventing over-winding of the hose and the like with a constant winding pressure. Since it can be entrained, it is effective in preventing deterioration of the hose, preventing deformation due to its own weight, and extending its life.

  Since the movable long reel of the present invention is configured as described above, for example, when this is used for a hose reel, the winding or pulling-out operation can be easily and efficiently performed without touching the hose. Can be done well. The invention can be applied to long objects such as handling of power cords in addition to uses such as flooding and chemical spraying, and has high utility value over a plurality of industrial fields.
