Therefore, it is not necessary to use a plurality of devices in accordance with the length of the cable 15 for laying in the underground pipeline 16. Further, since the winding diameter does not gradually increase by winding as in the conventional winding device, the drawing speed of the cable 15 can be stabilized.

  Furthermore, since the first to third reels 3A to 3C are arranged in a line along the transfer direction of the guide cord 2, the guide cord 2 can be reliably fed out without slipping. As a result, the delicate feeding speed of the guide cord 2 can be adjusted. Further, even when the guide cord 2 is pulled to one side (the second manhole opening 18 side) during the feeding, the guide cord 2 can be prevented from being pulled back.

  In addition, the said embodiment is an illustration and is not restrictive. For example, by configuring the control unit so that the first to third individual motors are collectively controlled, the first to third individual motors are simultaneously driven, and the first to third individual motors are driven by a single operation. The third reel can be rotated in cooperation with each other. In the above embodiment, an example in which three reels are provided has been described. However, the number of reels may be two, four or more, and may be appropriately changed depending on the force required to pull out the guide cord. it can.

  For example, when one reel and a driving motor corresponding to the reel are configured so that a cord or the like can be fed out with a force of 1 ton, 2 tons with 2 reels, 3 tons with 3 reels, 4 tons The number of reels may be changed according to the force required to feed out a cord or the like, such as 4 tons per reel. In addition, when one reel and a drive motor corresponding to the reel are configured so that a cord or the like can be fed out with a force of 1 ton or more, the number of reels is two, three, four,・ If you increase it, you can pay out cords etc. with the appropriate power.

  In the above-described embodiment, the first, second, and third reels can be switched at three rotational speeds of low speed, medium speed, and high speed by operating the corresponding operation levers. However, for example, an inverter device may be provided so that the speed of each reel can be finely adjusted.

  In addition, the diameter, shape, etc. of the reels can be changed as appropriate, and any configuration of drive motors (individual motors), speed reducers, etc. for driving a plurality of reels can be used. It is sufficient that a plurality of reels can be fed at a required speed. Furthermore, the feeding device according to the present invention can be applied not only to laying a cable but also to various other work processes.
