Description

[Detailed Description of the Invention] The present invention relates to a cable hanger, in which a particularly heavy overhead cable is held by a portion of the protective cover of the hanger band, and then one end of the hanger band is wrapped around the hanging wire.
Insert the annular part of the engagement fitting arranged at the end into a long length, then wrap the other overlapping part and insert the annular part into the elongated hole, and then insert the locking wire into the annular part. A cable hanger is disclosed that ensures the above-mentioned wrapped state.

For example, a triplex cable has three large diameter cables.
Since it is made of real twist, it has a large weight and has a large cross-sectional area, so it is easily affected by wind pressure.

This invention was devised to reliably suspend cables that have a large weight and are easily affected by wind pressure. To obtain a cable hanger that can be supported at a certain position, is easy to install, and can be tied to a fixed position as it receives the weight of the cable.

For this purpose, after the cable is held by a part of the protective cover of the hanger band, the overlapping part on the side of the engaging fitting having the annular part is wound around the hanging wire, and the annular part of the holding fitting is extended to a long length close to this. Insert the other overlapping part of the hanger band around the hanging wire above the overlapping part, insert the annular part into the elongated hole, and connect both ends of the hanger band wrapped around the hanging wire with this annular part. After being temporarily locked, a locking wire is inserted into this annular portion, and the arcuate portions at both ends of the locking wire are connected to the hanging wire to maintain a secure locking state.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the cable hanger according to the present invention, and FIG. 2 is a side view of FIG. , 4 indicates a locking wire.

First, to explain the hanger band 3, FIG. 3 is a plan view thereof, FIG. 4 is a plan view of FIG. 3 with the protective cover 5 removed, and FIG. 5 is a side view of FIG. The hanger band 3 is made of a band-shaped metal plate such as a stainless steel plate,
Both ends are folded back to form overlapping parts 6 and 7, which are joined by welding or the like.

A pair of elongated holes 8, 9 are provided through the overlapping portions 6, 7 in the longitudinal direction of the center thereof.

These elongated holes 8 and 9 are provided with engaging metal fittings 10 as will be described later.
The annular portion 11 of is inserted.

The center of the end of one of the overlapping parts 6 is cut out in a U-shape, and an engaging metal fitting 10 is disposed therein.

To explain the engagement tool 10 in detail, FIG. 6 is a front view, and FIG. 7 is a side view taken from the direction of the arrow ■ in FIG. The central portion thereof is wound approximately perpendicularly to the linear ends to form an annular portion 11.

The inner diameter of this annular portion 11 is large enough to allow the locking wire 4 to be sufficiently inserted therethrough.

The linear portions at both ends excluding the annular portion 11 are engaged with the overlapping portion 6.

Further, a linear reinforcing metal fitting 12 is wired to the overlapping portion 7 on the outside of the other elongated hole 9 .

Even if the end of the elongated hole 9 is broken, this reinforcing metal fitting 12 will come into contact with the engaging fitting 10 inserted into this elongated hole 9, and the engaged fitting 10 will be able to This is to prevent it from coming off.

A protective cover 5 made of resin and having a C-shaped cross section is engaged with the central portion of the hanger band 3.

FIG. 8 is a plan view of this protective cover 5, and FIG. 9 is a plan view taken from the direction of the arrow ■ in FIG. 3, and its flat portion abuts against the outer sheath of the triplex cable 1 to protect the outer sheath and ensure electrical insulation.

Next, to explain the locking wire 4, FIG. 10 is a side view of the locking wire 4. The locking wire 4 is made by bending and cutting a single metal wire, and the center portion thereof is straight. Therefore, the annular portion 11 of the engaging metal fitting 10 of the hanger band 3 can be inserted, and the annular portion 11 is prevented from coming out from the elongated holes 8 and 9.

In addition, both ends of the locking wire 4 are curved in an arc shape in opposite directions, and as shown in FIG. 2, they are locked to the outer periphery of the suspension wire 2 with a twisting force, so that they do not come off unexpectedly. There is no such thing.

That is, since both ends are arcuately curved in opposite directions, when this part is attached to the suspension line 2, a twisting force is generated in the straight part, which, combined with the force of the annular part 11, maintains the attached state. be done.

Next, the operation of the above embodiment will be explained with reference to the perspective views of FIGS. 11 to 13 in addition to FIGS. 1 and 2. To hold the cable 1 (Fig. 11), the engaging fitting 1
The overlapping part 6 on the 0 side is wrapped around the suspension wire 2, and the annular part 11 of the engaging fitting 10 is inserted into the elongated hole 8 adjacent to this (12th
figure).

Next, the other overlapping part 7 of the hanger band 3 is attached to the overlapping part 6.
Wrap it around the suspension line 2 from above, and insert the long hole 9 into the annular part 11.
(Figure 13).

In this state, both ends of the hanger band 3 are already wrapped and locked around the suspension line 2 by the annular portion 11.

The more each of the overlapping parts 6 and 7 is pulled by the weight of the triplex cable 1, the more the annular part 11 is pulled from one overlapping part 6 in the opposite direction to the other overlapping part 7.
The neck is tightened, making it impossible to insert or remove it.

Next, the locking wire 4 is inserted through the annular portion 11 (Fig. 2), and the arched portions at both ends exert a twisting force on the outer periphery of the suspension wire 2 at a position slightly away from the hanger strip 3. Then, the annular portion 11 of the engaging fitting 10 is inserted into the elongated holes 8 and 9.
It will be ensured that nothing will be left out.

At this time, in addition to the torsional locking force of the arcuate portion, the more the annular portion 11 is pulled in by the weight of the triplex cable 1, the more the locking wire 4 is pulled into the hanger strip 3.
As a result, the hanger band 3 is firmly connected to a fixed position on the suspension wire 2.

As described above, according to the cable hanger according to the present invention, after the cable is held by a portion of the protective cover of the hanger band, the overlapping part on the engaging fitting side having the annular part in the center is wrapped around the hanging wire. Insert the annular part of the engagement fitting into the elongated hole adjacent to this, wrap the other overlapping part of the hanger band around the hanging wire from above the overlapping part, insert the annular part into the elongated hole, and remove the annular part. By inserting a locking wire into the wire and anchoring the arched portions at both ends to the suspension wire, triplex cables with a large weight can be firmly tied in a fixed position for a long period of time, making it useful as a means of overhead wire. .
