The circulating rope 7 can be smoothly rotated in forward and reverse directions while being guided by the guide roller 17.

  In order to form such a laying device 1, a call rope having a rigidity (not shown) is pushed into the shooter 4 of the laying rail 2 in advance, and the circulating rope 7 is connected to the other end and then pulled back. The circulating rope 7 is accommodated in the shooter 4 along the laying path. Then, after the circulating rope 7 is accommodated in the shooter 4 of the pair of left and right rail bodies 3 and looped around, the respective end portions are respectively connected to the connecting holes 8 a of the connecting member 8 and formed in an annular shape. Next, the tension bolt 14 of the end attachment member 11 is screwed back and forth, and the circulating rope 7 is adjusted to a required tension.

  Next, in order to lay the cable C by the laying apparatus 1 of the present embodiment configured as described above, the circulating ropes 7 are accommodated independently in the pair of left and right rail bodies 3 and hung around to obtain the required tension. After the adjustment, the cable C is connected to the connection hole 8d of the protruding portion 8c of the connecting member 8, and a handle (not shown) is attached to the pivot shaft 16, and the rotating roller 15 of the end mounting member 11 is manually rotated. The circulating rope 7 is rotated using an electric rotating tool.

  In FIG. 1, when the circulating rope 7 is rotated in the direction of the arrow, the cable C connected to the connecting member 8 follows this and moves to the left in the figure, and is placed on the child girder 33 of the support 31. Placed. Therefore, after the cable C is moved to the other end of the laying path and pulled in as a whole, the cable C is detached from the connecting member 8 at the other end of the laying path.

  Here, a cable connector 9 is attached to the shooter 4 on the opposite side to which the connecting member 8 moves. Accordingly, in order to lay the cable C on the opposite beam 33 on the laying rail 2 as a boundary, the cable C is similarly connected by connecting the cable C to the cable connector 9 and rotating the circulating rope 7. can do.

  As shown in FIG. 1, if another cable C is also connected to the cable connector 9 on the left end side, the connecting member 8 can be connected by rotating the circulating rope 7 in the direction of the arrow in FIG. The cable connector 9 moves to the right in the figure. As a result, the two cables C can be laid on the support 31 at the same time simply by moving the circulating rope 7 from one end to the other end.

  As described above, the wiring / pipe material laying apparatus of this embodiment has two rail bodies 3 each made of a hollow cylindrical body having slits 4a continuous in the longitudinal direction, and is arranged along the laying path. Laying rails 2 and circulating ropes 7 respectively accommodated in the rail bodies 3 and stretched to rotate between the laying paths. By the circular rotation of the circulating ropes 7, the rail bodies 3 The cable C connected to the circulating rope 7 through the slit 4a or a nominal rope for laying the cable C is drawn along the laying path and laid.

  Accordingly, the circuit rope 7 is accommodated in the rail body 3 and reciprocates along the laying path. Therefore, the circuit rope 7 moves smoothly without being entangled with each other or being caught by a slack, and requires a particularly large rigidity or tension. Therefore, even a heavy cable C can be reliably pulled in. Further, the circulating rope 7 can be easily hung around the laying rail 2 by an operation such as feeding the calling rope into the shooter 4 first. Furthermore, since the end attachment members 11 having the tension bolts 14 are attached to both ends of the laying rail 2, the tension of the circulating rope can be easily adjusted.

  Next, a wiring / pipe material laying apparatus according to another embodiment of the present invention will be described with reference to FIGS. 7 and 10 are plan views showing the lower part of the horizontal section divided into two parts.

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

  7 and 8, the end mounting member 11 has bases 12 attached to both ends of the laying rail 2 via mounting screws 13a and mounting nuts 13b. The base 12 is provided with a rotating roller 15 and a guide. A roller 17 is attached, and further, a tension roller 19 is movably attached to the side via a tension roller holding base 18. The tension roller 19 has a shaft 19a that can move in a guide groove 20 formed in a direction perpendicular to the laying direction. The tension roller holding base 18 that holds 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 that holds the thumbscrew 21 in a fixed position is attached to the thumbscrew 21, and an engagement plate 23 that engages and moves with the tension roller holding base 18 is attached to the distal end portion.

This can be done by moving 18 following it. As the tension roller 19 is moved to the side, the circulating 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 the tension of the circulating rope 7 is desired to be larger than the tension shown in FIG. As shown in FIG. 10, the tension rollers 19 are moved outwardly away from each other. In this way, the tension of the circulating rope 7 can be easily adjusted to an arbitrary magnitude.

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

  In the figure, a receiver 31 formed in a substantially chevron shape and having a placement portion 35 for a cable C is juxtaposed at a predetermined interval in the laying direction. The connecting plate 2a for connecting the two left and right rail bodies 3 is placed, and after the mounting member 37 having a substantially T shape is placed on the connecting plate 2a, the mounting member 37 is connected to the bolt 38. Is attached to a nut 39 fitted into the support column 36 of the receiver 1, whereby the laying device 1 is assembled to the receiver 31.

  Here, the attachment member 37 has a T-shaped horizontal portion 37a formed in a substantially prismatic shape, and a vertical portion 37b formed in a columnar shape. The mounting member 37 moves up and down a certain stroke with respect to the connecting plate 2a of the laying rail 2. It can be moved. The vertical portion 37b of the attachment member 37 is fitted between the pair of rail bodies 3 so that the rotation in the horizontal direction is restricted.

  Therefore, as shown in FIG. 14, the horizontal portion 37 a is fitted between the rail bodies 3 of the laying rail 2, and the mounting portion 35 of the receiving tool 31 is placed on the rail body 3 of the laying rail 2. As shown in FIG. 15, the horizontal portion 37 a of the mounting member 37 is moved to the rail body 3 by rotating 90 degrees in the horizontal direction after the mounting member 37 is lifted up to the upper end and rotated horizontally. The mounting portion 35 of the receiving tool 31 can be switched to two states, a state suitable for storage and storage, in parallel with the rail body 3 of the laying rail 2.

  In this embodiment, as shown in FIG. 14, the horizontal portion 37 a of the attachment member 37 is inserted between the rail bodies 3 of the laying rail 2, and the placement portion 35 of the cable C in the receiving tool 31 and the laying rail 2.
