A laying rail 2 and a circulating rope 7 which is accommodated in the rail body 3 and is stretched to circulate between the laying paths. The cable C connected to the circulating rope 7 through the slit 4a or a call rope for laying the cable C is pulled in along the laying route and laid.

  Therefore, since the traveling rope 7 is accommodated in the rail body 3 and reciprocates along the laying route, the traveling rope 7 moves smoothly without being entangled with each other or hooked on a loose object, and requires extraordinarily large rigidity or tension. Thus, even a heavy cable C can be reliably pulled in. In addition, the patrol rope 7 can be easily wrapped around the laying rail 2 by an operation such as feeding the calling rope into the chute 4 first. Further, since the end mounting members 11 having the tension bolts 14 are attached to both ends of the laying rail 2, the tension of the traveling rope can be easily adjusted.

  Next, an apparatus for laying wiring and piping materials according to another embodiment of the present invention will be described with reference to FIGS. 7 and 10 are plan views showing a lower part which is divided into upper and lower parts in a horizontal section.

  This alternative embodiment differs from the previous embodiment in that the end mounting member 11 is different, and means for expanding the circulating rope 7 between the rotating roller 15 and the guide roller 17 on both sides to adjust the tension thereof. Is provided.

  7 and 8, a base 12 is attached to the end mounting member 11 via mounting screws 13a and mounting nuts 13b at both ends of the installation rail 2, and a rotating roller 15 and a guide are mounted on the base 12. A roller 17 is mounted, and a tension roller 19 is further movably mounted laterally via a tension roller holding base 18. The stretching roller 19 is configured such that its shaft 19a can move in a guide groove 20 formed in a direction perpendicular to the installation direction. The tension roller holding table 18 for holding the tension roller 19 can be moved along the guide groove 20 by tension roller moving means including a thumbscrew 21, a nut 22, and an engagement plate 23. A nut 22 for holding the thumbscrew 21 at a fixed position is attached to the thumbscrew 21, and an engagement plate 23 for engaging and moving with the tension roller holding base 18 is attached to a tip end thereof.

That is, in order to move the tension roller 19 to the side, the engaging plate 23 is moved by screwing and retreating the thumb screw 21 to both sides with respect to the nut 22 so that the tension roller holding base engaging with the nut 22 is engaged. 18 can be moved following the movement. In addition, along with moving the tension roller 19 to the side, the traveling rope 7 passes between the guide roller 17 and the tension roller 19 and intersects between the rotation roller 15 and the tension roller 19. Moving.

  Since the present embodiment is configured as described above, when it is desired to increase the tension of the circulating rope 7 to, for example, the tension shown in FIG. 10, the stretching rollers 19 move outwardly away from each other, as shown in FIG. In this way, the tension of the traveling rope 7 can be easily adjusted to an arbitrary size.

  In particular, in the case of the present embodiment, the tension roller 19 can be moved in the outward direction perpendicular to the installation direction by the thumb screw 21, so that the end mounting members 11 are connected to each other as in the embodiment described later. When connecting, there is no hindrance to the tension adjustment work. That is, if the thumbscrew 21 is moved in the installation direction, the operation of screwing the thumbscrew 21 back and forth in the installation direction becomes extremely difficult or impossible when the end mounting members 11 are connected. However, in this embodiment, since the thumb screw 21 is operated in the orthogonal direction, there is no such restriction. Further, the present invention is not limited to the case where the end mounting members 11 are connected to each other, but is also effective in a case where the operation in the laying direction cannot be performed due to space and space restrictions.
