Can be reused, and industrial waste disposal costs are not required.

  Further, according to the present attachment device 10 and the present attachment method, when the guide rollers 5 and 6 are rotated, the moving power cable protective tube 1 and the moving power cable 100 are sent in the axial direction, and the moving power is transferred. Since the cable 100 is pushed and inserted into the moving power cable protection tube 1, the moving power cable protection tube 1 can be easily and quickly attached to the moving power cable 100. That is, the moving power cable protection tube 1 can be attached while laying the moving power cable 100. As a result, even when the mobile power cable 100 is long, it is possible to significantly reduce the personnel, labor, cost, etc. required to protect the mobile power cable 100.

  Furthermore, since the distance between the first guide roller 5 and the second guide roller 6 can be adjusted, the first guide roller 5 according to the outer diameter of the moving power cable 100 and the moving power cable protective tube 1 or the like. By adjusting the distance between the second guide roller 6 and the second guide roller 6, it is possible to cope with various moving power cables 100 and moving power cable protection tubes 1. Moreover, this attachment apparatus 10 can be utilized also when removing the power cable protection tube 1 for movement from the power cable 100 for movement to which the power cable protection tube 1 for movement is attached. That is, with only the moving power cable protection tube 1 sandwiched between the first guide roller 5 and the second guide roller 6, the moving power cable protection tube 1 is only sent in the axial direction to move the moving power cable. The protective tube 1 and the moving power cable 100 can be easily and quickly separated. That is, the moving power cable protection tube 1 can be removed while winding the moving power cable 100, and personnel and costs can be significantly reduced.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above-described embodiment, the guide rollers 5 and 6 are rotated by pulling the moving power cable 100 and the moving power cable protective tube 1, but the guide rollers 5 and 6 are rotated. A motor and a rotation mechanism may be provided, and the guide rollers 5 and 6 may be rotated by power to send out the moving power cable 100 and the moving power cable protection tube 1.

  Further, although the guide rollers 5 and 6 can be moved and adjusted only in the vertical direction, they may be moved in the horizontal direction. Accordingly, the positional relationship between the guide rollers 5 and 6 can be adjusted in a more complicated manner, and the moving power cable 100 can be inserted into the moving power cable protective tube 1 appropriately and smoothly.

  Further, when the moving power cable protection tube 1 is removed from the moving power cable 100, the moving power cable protection tube 1 is held between the guide rollers 5 and 6. Alternatively, the moving power cable protection tube 1 and the moving power cable 100 may be separated by holding only 100. Moreover, although the case where the moving cable is a power cable has been described, it goes without saying that a moving cable such as a communication cable may be used.
