Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a hanger used for hanging various cables such as a power transmission cable and a communication cable on a messenger wire made of a steel stranded wire stretched between utility poles.

[0002]

[Prior art]

 As a conventional suspending device of this kind, a pulley for construction is suspended in the longitudinal direction of a messenger wire A made of a metal material stretched between utility poles as shown in FIG. By moving and guiding the communication cable B, a temporary tension is applied in parallel with the messenger wire A to temporarily construct the communication cable B, and the temporarily constructed communication cable B is sequentially arranged at predetermined intervals with respect to the messenger wire A to form a plurality of metal wires. The operator manually connects the hanger hanging devices C made by the company, and a communication cable B is stretched and suspended based on a messenger wire A that stretches between telephone poles.

As shown in FIG. 4, as an example of use of another type of suspending device, a steel wire or a flat steel material is coiled in advance by a coil suspending device D made of a non-stretchable helically formed wire. The messenger wire A and the communication cable B are bundled to carry out the suspension work, and the suspenders D are also formed to have a predetermined length, and a plurality of the suspenders D are individually used between the utility poles for the construction work.

[0004]

[Problems to be solved by the invention]

 However, in the above-mentioned prior art, when constructing between the utility poles of the communication cable B, the construction worker carries the heavy metal hangings C and D to a high place and brings them to the messenger wires A at equal intervals one by one. The messenger requires a large amount of labor to be installed while moving along the longitudinal direction of the wire A while binding the communication cable B and the messenger. The connection of wire A became loose, and there were concerns about unexpected dropouts and misalignment.

[0005] In addition, there is a danger of requiring considerable skill, particularly that it is necessary to bring a relatively long twisted coil-shaped hardware of the hanging tool D and to operate a special winding insertion jig to connect them. There are issues such as construction work.

[0006] As described above, the erection work using the hanging devices C and D according to the prior art is carried out at high altitudes by riding on a spacecraft or the like, so that work in mountainous areas or bad weather is completely anticipated. It was dangerous construction that was not allowed.

[0007]

[Means for Solving the Problems]

 According to the present invention, as shown in FIG. 1, an iron wire core 1 is formed into a tightly wound or roughly wound telescopic coil to solve some of the drawbacks described above. Is coated with paint 2 as a finishing treatment on the outer diameter. This helical iron wire is a tightly wound body or a coarsely wound body.

[0008] The outer periphery of the core material 1 is coated with paint to form a coil as shown in FIG. 2, and a messenger wire A and a communication cable B are bundled in parallel on the coiled inner race to form a bundle between telephone poles. The communication cable B is suspended from the messenger wire A by extending and connecting the coil shape in a tensile state.

More specifically, when the outer diameter of the communication cable B is erected between the electric poles by using the wire coil of the paint coating on the outer diameter, the construction worker simply forms a single coil between the electric poles. The wire coil is inserted into this messenger wire A in a pre-process operation of suspending a strong stranded messenger wire A made of steel that is stretched between utility poles by using the suspended wire coil hanging device 4. Hang it.

Then, the fixture 3 is engaged with the electric pole at the terminal of the wire coil.

[0011] Next, the leading end B 'of the communication cable B to be erected is inserted into the inner ring of the wire coil formed by hanging the contact coil, and is extended simultaneously with the end of the wire coil. The communication cable B is suspended between the utility poles using the messenger A as a guide, and each terminal is connected to the utility pole after each is extended to the tension state. However, the wire coil does not need the spring property to return to the original state after the tension. It is.

[0012]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. In FIG. 1, a coiled machine is used to form a stretchable coil or a coarsely wound coil with a core material 1 made of a metallic iron wire, and paint is applied along the outer periphery of the core material 1 by, for example, cutting. The core material 1 may be baked or baked in a pre-coil forming step.

Next, as another embodiment, the metal wire of the core material 1 described above is processed into a hollow pipe-shaped core material 1 'to reduce the weight of the wire coil as much as possible and to provide a tough body in the second embodiment. In this case, the outer periphery of the metal pipe is a coil-shaped body composed of a coating of paint or a resin film.

As described above, each core material 1.1 'is designed so that a wire coil can be selected according to the thickness and weight of the communication cable B.

As described above, for the coil-shaped telescopic wire coil, the dimensions of the raw wire, the diameter of the coil-shaped ring, the natural length of the coil-shaped coil, and the parameters such as the type of paint can be arbitrarily selected. In this embodiment, a fluororesin paint or a silicone / acrylic resin paint is desirable.

Thus, the coating of the core material 1.1 'with the outer peripheral paint is described in the effect of the present invention. D solves many shortcomings and embodies new features.

[0017]

[Effect of the invention]

 Since the present invention operates as described above, it has the following excellent effects. As described in Figure 1.2, by hanging a communication cable on a messenger wire that stretches between telephone poles and binding it, a coating material is coated with a core material of iron wire, and it is inexpensive and lightweight. It is possible to provide a wire coil that can greatly reduce the labor and relieve the danger of being able to perform the work of extending the coil winding with good property and to make the construction work safe in a short time.

In addition, by specifying the paint, baking finish can be achieved, heat resistance is improved, insulation resistance is good, weather resistance is good, service life is long, and frictional resistance is small at the time of elongation, so low traction force. It is possible to provide a wire coil that can fully utilize the properties of paint that is strong in elongation of the coating of the core material and tensile strength.

In addition, the coating of the core material employs a self-extinguishing non-combustible paint, so that even in the event of a fire in the vicinity of a communication cable, the coating of the wire coil core material burns along the extension line. The cable can be protected without any trouble such as the coating does not melt or fall off.However, the coating with resin may cause similar burning or melting. Can be provided.

In addition, by utilizing the characteristics of the coating material for the core material, when the coil is pulled and installed, each of the messenger coil, the communication cable, and the wire coil is tightly bound together into a bundle. In addition, it is possible to provide a wire coil that can be safely suspended without coating the coating of the wire coil or cracking the coating and exposing the core material.

Further, by forming the core material into a pipe shape, the total weight can be reduced and a tough wire coil can be provided.
