[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lashing coil mounting device for bundling, for example, a communication cable already laid, a support line of the communication cable, and a method of bundling the cable.

[0002]

2. Description of the Related Art In recent years, the Internet and personal computer communication have become widespread, and various information can be easily obtained from terminal devices such as personal computers installed in, for example, homes and offices via communication lines. Has become. However, with the growing communication demand,
For example, the number of communication cables installed on telephone poles or the like is increasing. Therefore, the administrator of the telephone pole instructs the user to bind and install the communication cable owned by the same user.

[0003]

By the way, as a method of bundling a communication cable, a newly installed communication cable is bound (lashed) with a support wire or another communication cable already supported by the support wire. The following are known as supporting methods. (1). First, a messenger wire is stretched between utility poles, and an automatic lashing winding device is moved along the messenger wire, and an existing communication cable (existing cable) and a new communication cable (new cable) are bound with an iron wire or the like. (2). After adding a new cable, it winds and binds an iron wire or the like that has been processed into a spiral shape to match the diameter of the existing cable and the support wire. The winding method of the spiral iron wire includes the bundled cable (existing cable, new cable,
In a state of being wound around a support wire, it is common to hold one end of the cable by hand, for example, and wind the other end while turning the outer circumference of the cable to be bound. (3). The cable to be tied is inserted into the inside of a coil made of, for example, a resin wire having sufficient strength to bind the cable to be tied, and after the cable to be tied is laid, One end is stretched, for example, fixed to one pole, and the other end is fixed to the other pole.

However, in the method shown in (1), it is necessary to install a communication cable and extend a messenger wire in order to move the automatic lashing winding device. Further, in the method shown in (2), the spiral iron wire has a length of only about one meter in the length of the cable to be tied. A spiral iron wire corresponding to the entire length is required, and a large amount of labor is required for the winding operation. Furthermore, in the method shown in (3), since the cable to be bound needs to be inserted into the coil in advance, the cable can be bound only when a new communication cable is installed. Therefore, for example, the method (1) or (2) is used to bind the existing cables.

[0005] As described above, when a new communication cable having no support wire is added and installed on a telephone pole or the like on which an existing communication cable is installed, a messenger wire is stretched or sufficient strength is provided. There is a problem that a great deal of labor is required because it is necessary to adopt a binding method.

As shown in FIG.
Are supported by, for example, an overhead wire support portion 51 a of a telephone pole 51, and further bundled by a lashing coil 60. Then, one end of the winding material 41 is connected to, for example, the wire support portion 5.
1a. From this state, the lashing coil 60
Is moved in the direction of the arrow E along the cable 30 to be bound, the winding material 41 gradually comes off spirally from the utility pole 51 side, for example, as shown in FIG. Can be bundled.

When the lashing coil 60 is further moved in the direction of arrow E, as shown in FIG. 6B, the cable 30 to be bound can be bound by the winding material 41 over substantially the entire length. In FIG. 6B, a broken-line circle F
When the area enclosed by is enlarged, the result is as shown in FIG. At the end of the lashing process,
When the surplus winding material 41 remains, it is removed from the split pipe 20. Further, the split pipe 20 is removed from the cable 30 to be bound by opening the hinge 21 with the fulcrum as a fulcrum. Then, as shown in FIG. 8B, by fixing the other end of the winding material 41 to the wire support portion 52a of the utility pole 52, the whole cable to be bound 30 can be held.

The lashing coil 60 may be formed by winding the winding material 41 by an amount corresponding to the cable 30 to be bound. That is, versatility can be easily given to the length of the cable 30 to be bound, and the winding material 41 can be used efficiently.

Further, in the examples shown in FIGS. 6 and 7, the example in which the lashing step is performed by removing the rotary drive unit 1 from the split pipe 20 has been described. It is also possible to mount the drive unit 1 and wind the winding material 41 at the same time as the bundled cables 30 are bundled. In this case, for example, the handle 14 of the rotary drive unit 1 is moved together with the split pipe 20, and when the lashing process up to the electric pole 52 is completed, the position to be the other end of the wound wire 41 is cut off, and the end is cut off. Is fixed to the overhead wire support portion 52a.

Further, it is also possible to wind the winding material 41 relatively roughly around the split pipe 20 and, when the winding is completed, pull the other end of the winding material 41 and guide it to the utility pole 52 to fix it. . In this case, it is also possible to remove the split pipe 20 when the desired amount of the winding wire 41 has been wound. Therefore,
It is not necessary to temporarily fix the other end of the winding material 41 to the split pipe 20.

Further, in the present embodiment, the example in which the split pipe 20 is opened and closed by the hinge 21 has been described. However, since the tubular member only needs to be detachable from the cable 30 to be bound, it is not necessarily required. There is no need to provide the hinge 21. For example, it is possible to realize a cylindrical shape by fitting the ends of the gutter portions 20a and 20b only with the uneven portions.
