  According to the cable feeding device according to claim 1, the cable bundle mounting carriage having three casters is formed on the upper surface of the base member with little friction without the three casters floating from the base member around the central shaft member. Since it rotates, a cable can be smoothly drawn out from a cable drum or a cable bundle wound in a coil shape. Moreover, since the central shaft member can be detached from the cable bundle mounting carriage and the base member, the entire apparatus can be easily moved.

  The cable feeding device 1 according to the present invention is capable of feeding a cable from the cable bundle 50 by rotating a cable bundle 50 in which a power cable is mainly wound in a coil shape within a horizontal plane. Here, the cable bundle 50 includes those wound around the cable drum 51 as shown in FIG. 3 and those not wound around the cable drum 51 as shown in FIG. 4.

  As shown in FIGS. 1 and 2, the cable feeding device 1 includes a central shaft member 10, a cable bundle mounting carriage 20, and a base member 30. Hereinafter, each component of the cable feeding device 1 will be described.

  The central shaft member 10 is a member having a circular cross section and serving as a center of rotation. The central shaft member 10 is a round bar member having an outer diameter that can be inserted into a circular center hole (not shown) provided at the center of the cable drum 51 and longer than the height of the cable drum 51. The central shaft member 10 is preferably a hollow circular tube (single tube) in order to reduce the weight and facilitate the movement of the cable feeding device 1, but it may be a solid member.

  The cable bundle mounting carriage 20 is provided with a circular inserted member 21 through which the central shaft member 10 can be inserted, and three radially disposed around the inserted member 21 at intervals of 120 degrees, and the cable bundle 50 is provided on the upper surface. It can be placed and comprises a placing member 22 having casters (universal wheels) 23 on the lower surface.

  The inserted member 21 is a circular tube member having an inner diameter through which the central shaft member 10 can be inserted. Here, the mounting member 22 is a lip groove steel (C-shaped steel), and is radially welded around the inserted member 21 with the opening of the lip groove steel facing upward. As described above, since the three placing members 22 are provided radially around the inserted member 21 at intervals of 120 degrees, a sufficient welding surface can be taken, and the cable bundle placing carriage 20 is constructed firmly. be able to. A caster 23 is provided on the lower surface of each of the three placement members 22. As described above, since the three casters 23 are provided, the cable bundle mounting carriage 20 can be stably rotated with three-point support. An attachment hole 22 a that is a through hole for inserting a wood screw when attaching the cable bundle placement carriage 20 to the cable drum 51 is formed at an intermediate position of each of the three placement members 22. Although not shown in the drawings, the mounting member 22 may be provided with an extension member for extending the length according to the diameter of the cable bundle 50 to be mounted, and the length of the mounting member 22 itself may be set. It is good also as expansion and contraction.
