Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated cable hanger in which hooks at both ends are hooked on a messenger to form a loop-shaped support portion made of an insulating portion and an overhead cable is suspended therethrough. More specifically, the present invention relates to an improvement in a hook portion of an insulated cable hanger.

[0002]

2. Description of the Related Art As shown in FIG. 4, an insulated cable hanger 10 is mounted on a messenger 106 suspended between telegraph poles 109, 109 using an insulated cable hanger 107.
7 may be suspended before the overhead cable 105 is extended. The overhead cable 105 has hooks 102a at both ends,
The loop 102b is provided so as to form a loop-shaped support portion 104 for supporting the overhead cable 105 with the insulating portion 108 by hooking the 102b on the messenger 106.

The insulated cable hanger 107 is shown in FIG.
As shown in the figure, a wire 101 having hooks 102a and 102b formed at both ends and an insulating tube 10 covered therewith.
The hooks 102a and 102b protruding from both ends of the insulating portion 108 formed of the insulating tube 103 are hooked on guide lines called messengers, thereby supporting the overhead cable 105 with the insulating portion 108. 104 is formed. The hooks 102a and 102b of the insulated cable hanger 107 are combined with an inverted U-shaped hook 102a and an inverted L-shaped hook 102b so that once hooked on the messenger 106, they do not come off easily. . And
The inverted U-shaped hook 102a is slightly twisted so as to cross diagonally when hooked on the messenger 106. Therefore, when the inverted U-shaped hook 102a is hooked on the messenger 106, the inverted L-shaped hook 102b at the other end is separated from the messenger 106 and turned back. The inverted L-shaped hook 102b at the other end is provided so that it can be attached to and detached from the messenger 106 simply by moving it in the horizontal direction. Therefore, the insulated cable hanger 107 moves the inverted L-shaped hook 102b at the other end in the back direction so that the inverted U-shaped hook 102a is hooked on the messenger 106, and then the entire insulated cable hanger 107 is twisted. Then, the messenger 106 is attached to the messenger 106 by passing the lower side of the messenger 106 and hooking the messenger 106. The inverted L-shaped hook 102 thus hooked on the messenger 106
Since b is urged and pressed toward the messenger 106 by the elastic force generated by twisting the wire 101, it does not come off unless a strong external force in the opposite direction is applied.

Accordingly, a pair of hooks 102a, 10a
There is an order of hooking between the hooks 2b. If the hook is mistakenly hooked on the messenger 106 first from the inverted L-shaped hook 102b, even if the hook U is hooked on the messenger 106b, the L-shaped hook 10
2b comes off the messenger 106, and the insulated cable hanger 107 cannot be bent. Therefore, when hooks 102a and 102b are hooked on messenger 106, it is necessary to identify hooks 102a and 102b.

[0005]

However, discriminating between the inverted L-shaped hook 102b and the inverted U-shaped hook 102a, which are not so different in shape, tires the eyes of the worker unnecessarily, and furthermore, the hooks 102a, 102b If the order is wrong, it is necessary to redo the order, and there is a problem that the working efficiency is deteriorated.

[0006] In addition, such overhead wire work of the overhead cable 105 is not always performed only in the daytime, and furthermore, since there are various locations of the overhead wire, the work is sometimes performed under insufficient lighting conditions. There is also. When the overhead wire work is performed in such a situation, the hooks 102a, 1
It is even more difficult to identify 02b, but even so, there is a situation in which the eyes of the user tend to look too tight and cause excessive eye fatigue.

However, even in such a case, it is needless to say that quick and reliable wiring work of the aerial cable 105 is required, and for this purpose, it is necessary to quickly and surely mount the insulated cable hanger 107. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an insulated cable hanger capable of performing an aerial work of an aerial cable quickly and reliably both day and night.

[0009]

In order to achieve the above object, the invention according to claim 1 comprises an insulating portion and a pair of hooks provided at both ends of the insulating portion, and the pair of hooks is used as a messenger. A hook-shaped insulating section is formed by the insulating section, and an overhead cable is passed through the inside of the supporting section so that the overhead cable is suspended on the messenger. ing.

[0010] In this case, even in the work of wiring the overhead cable in a situation where the amount of illumination is small at night or the like, since one hook of the insulated cable hanger can be easily recognized by light emission, the hook to be hooked first can be recognized. In particular, when the light source is provided on the hook hooked first on the messenger as in the invention according to claim 2, the inverted U-shaped hook to be hooked first can be recognized, and its shape, orientation, and position can be recognized. And so on. Therefore, it is possible for the worker to hook the hook without having to check the shape of the hook one by one. The work for supporting is facilitated.

Further, in the insulated cable hanger according to the third aspect, the luminescent source is a fluorescent paint or a luminescent paint. In this case, the hook of the insulated cable hanger can be made to emit light by night lighting or the like without particularly requiring a power supply or an appliance. Further, even in the daytime, the hook can be identified by the color of the paint.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on an example of an embodiment shown in the drawings.

FIGS. 1 and 2 show an embodiment of the insulated cable hanger of the present invention. The insulated cable hanger 7 has no particular feature in the structure itself, and is constituted by an insulating portion 8 and a pair of hooks 2a and 2b provided at both ends of the insulating portion 8 as in the related art. 2b
Is hooked on the messenger 6 to form a loop-shaped support portion 4 by the insulating portion 8, and the overhead cable 5 is passed inside the support portion 4 so that the overhead cable 5 is suspended and supported on the messenger 6.

The hooks 2a and 2b are used to hook the insulated cable hanger 7 to the messenger 6 and suspend the hook. The hooks 2a and 2b obliquely intersect when the hook 2a is hooked on the messenger 6. The other hook 2b is formed in a substantially inverted L-shape in the same direction. Regarding the shape of the hooks 2a and 2b of the present embodiment,
As shown, the hook 2a is formed to be substantially U-shaped, and the hook 2b is formed to be substantially L-shaped.
The shapes and the like of a and 2b are not particularly limited. In this embodiment, the hooks 2a and 2b are made of metal. However, the hooks 2a and 2b are not limited to these as long as they can withstand the load of the overhead cable 5, and may be made of, for example, reinforced plastic or another material. It does not matter. Thus, the plastic or light metal hook 2a,
If 2b is used, it goes without saying that the weight of the insulated cable hanger 7 can be reduced. Also, a hook 2 made of an insulating material such as reinforced plastic is used.
Use for a and 2b is suitable for increasing insulation.

The hook 2a, which is one of the pair of hooks 2a and 2b and is hooked on the messenger 6, is provided with a light emitting source 9 for improving visibility. The light-emitting source 9 in the present embodiment is a fluorescent paint or a light-emitting paint of a color such as yellow or orange applied to the hook 2a that stands out even at night, and emits light even at night, as shown by a black portion in the figure. Alternatively, it can be easily recognized by being partially applied. In this embodiment, the fluorescent paint is yellow, but the color is not limited to this.

The insulating portion 8 is made of, for example, an elastomeric insulating material such as rubber, and is formed to have sufficient strength to support the weight of the overhead cable 5. This insulating part 8
The shape such as the length and thickness of the overhead cable 5 is not particularly limited, and may be appropriately modified based on the size and weight of the overhead cable 5 or the manner in which the overhead cable 5 is wired. That is, it is possible to use the insulating portion 8 formed of an insulating material having no flexibility so that the shape does not change, or to use a case where there is no risk of electric shock because the overhead cable 5 is not an electric wire or the like. It is also possible to use a non-insulating material. In the present embodiment, a flexible insulating portion 8 is used which is composed of a wire 1 formed in a cable shape and an insulating tube 3 covered with the wire 1 and having the above-mentioned hooks 2a and 2b attached to both ends thereof. ing.

According to the insulated cable hanger 7 configured as described above, the hook can be identified by the color of the paint in the overhead wire work in the daytime, and which hook should be hooked on the messenger 6 first. Easy to judge. Furthermore, since the hook 2a can always emit light even when the overhead cable 5 is wired at night or the like, the U-shaped hook 2a to be hooked first can be reliably recognized. Therefore, the work of hooking the insulated cable hanger 7 on the messenger 6 is performed reliably, and the overhead cable 5 can be reliably and quickly supported by the loop-shaped support portion 4 formed by the insulated cable hanger 7. In this case, the loop shape in this case is sufficient as long as the overhead cable 5 can be suspended, and does not mean a completely annular shape, but a U-shaped or V-shaped as shown in FIG. Includes cases that may occur. Thus, the insulated cable hanger 7 of the present invention is suitable for use in the overhead work of the overhead cable 5 at night, and the overhead work can be performed reliably and quickly even at night. In addition, according to the means using the fluorescent paint, since it can be used simply by applying the paint to the hooks 2a and 2b of the conventionally used insulated cable hanger 7, it is simple and cost-effective. It also has the advantage.

The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in the present embodiment, the hook is coated with the fluorescent paint, but it goes without saying that other means may be used as long as the visibility is improved at night. Therefore, the means for emitting light from the hook 2a is not limited to a luminescent material such as a fluorescent paint. For example, a light emitting source that blinks or lights up may be incorporated in the hook 2a to emit light.

In this embodiment, the hook 2a hooked first is provided with a light emitting source.
It is also possible to perform the overhead wire work by providing a light emitting source to b and recognizing the side without the light emitting source as the hook 2a. In other words, the inverted L-shaped hook 2b side may be colored with a fluorescent paint or a luminescent paint, or may emit light by other light emitting means.

[0020]

As is clear from the above description, in the insulated cable hanger according to the first aspect of the present invention, since one of the pair of hooks is provided with a light emitting source, it can be used even at night or at night. The hook hooked first can be reliably recognized by the light emission of one hook. As a result, the work of hooking the insulated cable hanger on the messenger is assured, and the overhead wire work becomes easier. Especially,
In the case where the messenger is provided with the light emitting source on the hook hooked first, the inverted U-shaped hook to be hooked first can be recognized, and the shape, direction, position and the like of the hook can be recognized. It can also be recognized. Therefore, it is possible for the worker to hook the hook without having to check the shape of the hook one by one. This makes it easier to perform the work of supporting the overhead cable inside. Thus, the overhead wire work can be performed reliably and quickly even at night.

Further, in the insulated cable hanger according to the third aspect, since the luminescent source is a fluorescent paint or a luminescent paint, the hook of the insulated cable hanger emits light by night illumination without requiring a power source or an appliance. be able to. Moreover, the means using the fluorescent paint is simple and inexpensive. Further, even in the daytime, the hook can be identified by the color of the paint.
