Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gable plate for packing insulators used for packing a series of insulators such as suspension insulators.

[0002]

2. Description of the Related Art Generally, when packing an insulator string, a packing method as shown in FIGS. 13 to 15 is adopted.
That is, the four box-shaped packing plates 32 are connected by the wires 35 to form the packing frame 31, and the packing frame 31 accommodates the insulator string 33 including the plurality of suspension insulators 34. Was wound and the insulator frame 33 was fastened and fixed by the packing frame 31. Further, a pair of end plates 36 and 37 are attached inside both ends of the packing frame 31 to prevent the insulator string 33 from coming out to the outside and to keep the shape of the packing frame 31.

In the conventional structure, the insulator 33 is used.
The end plate 36 on the side opposite to the cap metal fitting is formed into a square frame with a plurality of nails by using a pair of wood vertical bars 38, a pair of wood vertical connecting members 39, and a pair of wood horizontal bars 40. It was assembled and fixed in a shape. Further, the end plate 37 of the insulator string 33 on the side facing the pin fitting is a pair of wood vertical bars 41.
And a pair of wood horizontal rails 42 are assembled and fixed in a rectangular frame shape with a plurality of nails.

[0004]

However, in this conventional structure, the end plate 36 on the side of the cap fitting attaches and fixes each pair of vertical bars 38, vertical connecting members 39, and horizontal bars 40 by a plurality of nails. However, there is a problem that manufacturing including nailing is troublesome and costly.

Further, in this conventional structure, the end plate 36 is provided.
Is formed in a square frame shape, and when a load is applied to the packing frame 31 from the outside in the packed state of the insulator string 33, the end plate 3
6 is transformed into a rhombus shape, the packaging frame 31 is also transformed, and the insulator string 3
There was a problem that 3 was likely to be damaged.

Further, in this conventional construction, the end plate insulator 34 may be inclined as shown by the chain line in FIG. 13, because the end plate 36 on the cap fitting side does not have a function of preventing the insulator 34 from being inclined. Therefore, conventionally, it is necessary to fix the tilt prevention member 43 on the inner surface of the packing frame 31 to prevent the tilting of the insulator 34, which causes a problem that the structure of the packing frame 31 becomes complicated.

The present invention has been made by paying attention to such problems existing in the prior art. The purpose of the packing frame is that it can be easily manufactured and the cost can be reduced, there is no risk of deformation even if a load is applied in the packed state, and the tilting of the insulator is prevented. Another object of the present invention is to provide a gable plate for packing insulators that does not need to be provided with a tilt prevention material.

[0008]

In order to achieve the above object, in a gable plate for packing insulators according to the present invention, a gable plate body is integrally formed in a substantially flat plate shape, and the gable plate body is projected inward at the center thereof. In this case, a cone-shaped protrusion is formed to be joined to the outer surface of the cap portion of the insulator, and a through hole for inserting the cap metal fitting of the insulator is formed at the center of the protrusion.

[0009]

In the gallboard for packing insulators constructed as described above, since the gable board body is integrally formed, it is easy to manufacture and the cost can be reduced. Further, since the end plate main body is integrally formed in a flat plate shape, when the end plate is used to package the insulator string, the end plate is not likely to be deformed even if a load is applied to the packing frame. Therefore, it is possible to reliably prevent the insulator string in the packed state from being damaged by the load.

Further, a protrusion is provided at the center of the gable plate body so as to project inward, and this protrusion is joined to the outer surface of the cap portion of the insulator at the end to prevent the insulator from tilting. Therefore, it is not necessary to provide an insulator tilting prevention member on the packaging frame, and the structure of the packaging frame can be simplified.
