On the other hand, the traveling rope 21 is provided with a cable 41 or a pull-in rope for pulling in the cable 41.
Is formed of a wire, a fuel line rope, or the like that can withstand being pulled into the laying path 3. The traveling rope 21 is, for example, 1
By hooking the rope around the two pull-in rollers 11 and inserting the rope into the wire grip 22 shown in FIGS. 9 and 10 from both sides, the rope can be irremovably connected in a loop. It is to be noted that the traveling rope 21 can be adjusted to a tension at which the space between the draw-in rollers 11 can be rotated by inserting and loosening the adjustment pin 23 into the wire grip 22. A cable 41 or a drop-in rope is connected to the circulating rope 21 via a connector 42.

Next, a method of drawing a cable or the like into the laying path of the receiving device by using the drawing device of the present embodiment configured as described above will be described.

The two draw-in rollers 11 are previously fitted to and attached to the metal wire 4 at a predetermined distance in the direction in which the receiving member 2 is laid. Then, a loop rope 21 is wrapped around the two ropes, both ends are connected by using a wire grip 22 or the like, and the tension is adjusted with an adjustment pin 23 to be stretched between the draw-in rollers 11 in a loop. Next, a cable 41 is connected to the circulating rope 21 on one side of the laying path 3 of the receiving device 2 using a connecting tool 42, and the circulating rope 2 is connected to the other end of the laying path 3 of the receiving device 2.
1 and 2, the cable 41 is drawn into the laying path 3 as shown in FIGS. Then, when the cable 41 is pulled to the other end of the installation path 3 of the receiving device 2,
Remove the cable 41. As described above, the cable 41 can be easily pulled into the installation path 3 of the receiving member 2.

Here, the circling of the circulating rope 21 may be carried out manually by hand, or may be carried out using a driving device. At this time, one of the parallel ropes of the circulating rope 21 protrudes outside along the installation direction from the bottom 5 of the receiving member 2, so that the traversing rope 21 is approached from below the receiving member 2 even in the middle of the installation direction. be able to. Therefore, the circling operation of the circulating rope 21 can be easily performed. The same applies to a case in which the traveling rope 21 is attached to the side portion 6 of the receiving device 2 as shown in FIG. 11 described later, and the traveling rope 21 can be drawn from the side of the receiving device 2.

In the above-described embodiment, the case where the cable 41 is directly drawn in is shown. However, when the weight of the cable 41 is large, the drawing device 1 is used to temporarily lay a drawing rope (not shown). The cable 41 can be pulled back on the path 3 and then connected to the cable 41 at one end of the rope, and the cable can be pulled back at the same time.

As described above, the pull-in device 1 according to the present embodiment is configured such that the metal wire 4 is disposed at a predetermined distance in the direction in which the cable 41 is laid, and is substantially orthogonal to the direction in which the laying path 3 of the receiving member 2 is formed. And a pair of pull-in rollers 11 which are attached to the outside from the side and rotate around the metal wire 4 as an axis, and the pair of pull-in rollers 1
And a patrol rope 21 for pulling the connected cable 41 or a pull-in rope for pulling in the cable 41 into the laying path 3 by the rotation between the pull-in rollers 11.

Accordingly, the pull-in roller 11 can be formed with a simple configuration of being divided into two or notches, and the pull-in roller 11 can be easily mounted later on the receiving member 2 formed in a mesh shape with the metal wire 4. be able to. And the traveling rope 21 wrapped around the two pull-in rollers 11
The cable 41 can be easily constructed with a simple configuration just by rotating
Alternatively, the pull-in rope can be pulled into the laying path 3 of the receiving device 2.

In each of the above embodiments, the retracting roller 1
1 is attached to a metal wire 4 disposed at the bottom 5 of the receiving member 2 at right angles to the direction in which the laying path 3 is formed.
As shown in FIG. 1, it may be attached to the metal wire 4 on the side part 6 of the holder 2. In the case of this embodiment, in particular, since the pull-in roller 11 and the traveling rope 21 are attached to the side portion 6 instead of the bottom portion 5, the laying path 3 can be widely used.

In the above embodiment, only two pull-in rollers 11 are attached to the receiving member 2. As another embodiment, as shown in FIGS. 12 and 13, two pull-in rollers 11 are provided. If necessary, an appropriate number of auxiliary rollers 31 can be attached. In FIGS. 12 and 13, an auxiliary roller 31 having a rope holding concave portion 32 is provided on a metal wire 4 such as a bent portion of the receiving member 2, and a circulating rope 21 stretched between a pair of pull-in rollers 11. Is held in the rope holding recess 32 of the auxiliary roller 31. In the case of this embodiment, even when the receiving tool 2 has a bent portion, the circulating rope 21 can be wound around, and when the distance between the pair of circling ropes 21 is long, the circulating rope 21 is stably rotated. It has the effect of being able to.

Next, still another embodiment will be described with reference to FIGS.
Shown in

Referring to FIG. 14, the pull-in roller 11 is
Is attached to the metal wire 4 disposed at right angles to the installation direction at the bottom 5 of the base member, so that the distance between the pair of left and right flanges 11a is increased, so that the cable 41 or the pull-in rope can be further supported at this portion. Have been. That is, two types of deep and shallow concave portions having a step portion 11b are formed between the flange portions 11a of the pull-in roller 11, and only the small-diameter circular rope 21 is accommodated in the deep concave portion at the center portion. A rope holding concave portion 11c for holding is formed, and a shallow concave portion is integrally formed with a cable supporting concave portion 11d for accommodating and supporting a medium- or large-diameter cable 41 or a pull-in rope. The cable supporting recess 11d corresponds to a supporting portion described in claims. Here, the auxiliary roller 31 may similarly form a support recess for supporting the cable 41 or the pull-in rope. In addition, although the said support part is provided with the flange part 11a and is formed between it, if the cable 41 or a pull-in rope can be stably supported, it is not necessary to necessarily provide the flange part 11a.

If the pull-in roller 11 or the auxiliary roller 31 of this embodiment is used, these rollers
In addition to guiding the first rotation, the cable 41 or the pull-in rope connected to the patrol rope 21 is supported by the supporting recess of the roller, so that the pull-in force when the heavy cable 41 is pulled in can be reduced. In addition, receiving device 2
The cable 41 or the pull-in rope can be stably pulled into a fixed position in the width direction of the receiving member 2 at the bent portion or the like.

Although FIG. 14 shows an example in which a step 11b is formed in the recess between the flanges 11a, FIG.
As shown in FIG. 5, a concave portion between the flange portions 11a may be formed in a V-shape, a rope holding concave portion 11c may be formed at the bottom, and a cable supporting concave portion 11d may be formed at the upper portion.

Further, the pull-in roller 1 provided with a support recess such as a cable support recess 11c for supporting the cable 41.
As shown in FIG. 16, a plurality of pull-in devices 1 each including the auxiliary roller 31 and the circulating rope 21 may be provided in the width direction of the receiving member 2. In this case, in particular, the laying path 3 can be formed without meandering the plurality of cables 41 or the lead-in ropes.
And can be retracted with a small force.

In addition, as shown in FIG. 14 at the bottom 5 of the receiving device 2 and at the side 6 of the receiving device 2 as shown in FIG. If the width is formed to be substantially the same as the interval between the matching metal wires 4, there is no deviation in the width direction of the draw-in roller 11 between the adjacent metal wires 4, so that the traveling rope 21 or the draw-in rope can be stably rotated. it can.
