[Industrial applications]

 The present invention relates to an improvement of a vehicle for a communication cable overhead wire used for a work of connecting a communication cable between utility poles.

[0002]

[Prior art]

 The work of connecting the communication cable is carried out by attaching the wagons for the communication cable overhead wire to the suspension line stretched between the electric poles at regular intervals, and then pulling the cable on the pulley section of the gold car. In the conventional overhead line work, as shown in FIG. 3, it is composed of a pair of sandwiching pieces 20, a pulley 21 pivotally attached to the lower part of the sandwiching pieces 20, and a screw 22 for tightening the upper end of the sandwiching piece 20. The overhead wire car B was used. The gold wheel B is attached to the suspension wire 23 by sandwiching the suspension wire 23 from both sides by the upper ends of a pair of holding pieces 20 which are located above the pulley 21 through which the cable 24 is passed. Fix with screws 22 and attach.

Next, the communication cable 24 is placed on the gold wheel B and pulled to extend the wire. When this wire extension work is performed, a strong tension from the cable 24 is applied to the gold wheel B. , Acts as a force to loosen the screw 22. In particular, when the direction of the cable 24 is changed by transferring from one suspension line 23 to the other suspension line 23 at the intersection of the suspension lines 23, the tension due to the direction change of the cable 24 becomes large, and A force is applied in the direction of dropping from the suspension line 23. As described above, when the screw 22 is loosened due to vibration or tension during work, the suspension wire 23 is disengaged from between the sandwiching pieces 20, and the gold wheel B, which is fixed by sandwiching the suspension wire 23, disengages from the suspension wire 23 and falls. there were.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to improve the gold wheel so that the wire car for cable overhead wire itself does not drop from the hanging wire even if the sandwiching piece that was fixed with the screw comes off the hanging wire due to loosening or removal of the screw. To do.

[0005]

[Means for Solving the Problems]

 The wire car 1 for a cable overhead wire of the present invention includes a pair of sandwiching pieces 2 for sandwiching a suspension wire 11 suspended between electric poles from both sides at the upper part thereof, and a sandwiching piece 2 by screwing both sandwiching pieces 2 together. In the wire car A for cable overhead wire A, which is composed of the screw 3 for attaching the cable to the suspension wire and the pulley 6 attached to the lower portion of the holding piece 2 for mounting the communication cable, the wire is derived from the holding piece 2. The suspension wire 11 is inserted through the annular body 8 described above.

To use this, the suspension wire 11 is passed through the facing portion located above the sandwiching pieces 2, sandwiched by the upper ends of both sandwiching pieces 2, and fastened with screws 3. Further, the suspension wire 11 is passed through the annular body 8 connected to the holding piece 2 by the wire 9. After the gold wheel 1 is attached to the suspension wire 11 in this way, the communication cable 12 is placed on the pulley portion 6 below the sandwiching piece 2 and the cable 12 is pulled, whereby the cable 12 is erected.

Accordingly, even when the suspension wire 11 is disengaged from the holding portion at the upper end portion of the holding piece 2 due to loosening or disengagement of the screw 3 in the overhead wire work of the cable 12, the wire guided from the upper holding portion of the holding piece 2 is pulled out. Since the gold wheel 1 is connected to the suspension line 11 by the annular body 8 attached to 9, the gold wheel 1 does not hang from the suspension line, and the gold wheel 1 does not fall from the suspension line 11.

[0008]

【Example】

 Hereinafter, the present invention will be described with reference to the illustrated embodiments. FIG. 1 shows a perspective view of a gold wheel 11 of the present invention. The pair of holding pieces 2 constituting the gold wheel 1 of the present invention have a structure in which the upper ends face each other and hold the suspension wire 11, and the holding grooves 4 are provided on the opposite surfaces over the entire length in the width direction of both pieces 2. It is formed, and the screw 3 is installed below the holding groove 4. The screw 3 has its threaded portion screwed from a through hole formed in one holding piece 2 into a screw hole cut in the other holding piece 2. The lower portions of both holding pieces 2 are curved outward, and a pulley shaft supporting through hole 5 is formed in the lower end portion of one holding piece 2. At the lower end of the other sandwiching piece 2, a weight-type plastic pulley 6 is cantilevered by a cantilever shaft 7.

The free end of the cantilever shaft 7 is adapted to be inserted into the above-mentioned through hole 5, and as shown in FIG. The free end of the cantilever shaft 7 is supported and used by the through hole 5. On the contrary, when the upper screw 3 is loosened, as shown in FIG. 2, one holding piece 2 comes off and the cantilever shaft 7 comes off from the through hole 5.

A hook portion 10 is attached to the upper end of one of the sandwiching pieces 2, and a wire 9 is inserted at the apex of the hook portion 10. The annular body 8 is connected to the other end of the wire 9. The annular body 8 is composed of a substantially C-shaped locking portion 8a and a ring 8b pivotally attached to the opening of the locking portion 8a, and the base of the ring portion 8b is a spring (not shown). It is pressed and biased in a direction to close the opening portion of the locking portion 8a. Therefore, the locking portion 8a can be opened by tilting the ring 8b against the elastic direction of the spring.

To use the gold wheel 1 of the present invention, the suspension wire 11 is passed through the holding groove 4 located at the upper part of the holding piece 2, sandwiched by the upper ends of both holding pieces 2, and fixed by the screw 3. Further, the wire 9 is bent to press the locking ring 8b of the annular body 8 to open the locking portion 8a, insert the suspension wire 11 into the annular body 8, separate the ring portion 8b, and close the locking portion 8a.

In this way, after the gold wheel 1 is attached to the suspension wire 11 at a predetermined interval, the communication cable 12 is placed on the pulley 6 between the holding pieces 2, and then the cable 12 is pulled to pull the utility pole. Install a cable between them.

During this erection work, a large tension or vibration is applied to the gold wheel 1 from the cable 12, which causes the screw 3 to loosen or come off. When the suspension wire 11 is disengaged from the sandwiching groove 4 in the opposing portion of the upper end of the sandwiching piece 2, the gold wheel 1 falls off from the suspension wire 11. Further, when the screw 3 is loosened a lot or completely comes off, the shaft end (free end) of the pulley shaft 7 comes out from the shaft supporting through hole 5 of the holding piece 2 which is not stopped by the nut. The cable 12 is disengaged from the pulley 6. However, at this time, in the gold wheel 1 of the present invention, since the suspension wire 11 also passes through the annular body 8, the gold wheel 1 is hung by the annular body 8 through the wire to the suspension wire 11 and does not fall.

[0014]

[Effect of device]

 According to the present invention, since the suspension wire is inserted through the annular body led out from the sandwiching piece, even if the screw is loosened and the gold wheel falls off, the gold wheel is suspended by the annular body on the suspension wire. , There is no such thing as a gold car falling on the ground.
