Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spacer for packing a suspended insulator string, which is used when packing a suspended insulator string in a double-row framework.

(Prior art) Conventionally, when packing suspended insulator chains in double rows, the insulator chains are housed in opposite directions in a frame made of boards connected in a slatted manner and assembled using wire bands. As a spacer to prevent the insulator links from coming into contact with each other, a plurality of wooden boards are erected within the frame with both ends of the boards in contact with the cap metal fittings of the insulator links, but the heavy insulator links are In order to have a sufficient buffering effect against the insulators, the wood boards that serve as the spacers must be quite strong, which means that the volume of the framework is large relative to the size of the insulators, and it takes time and effort to assemble and store the spacers. However, there were also problems such as high packaging costs.

(Purpose of the invention) This invention solves these conventional problems and
This spacer was developed for the purpose of creating a spacer for packaging insulator chains that can reduce the volume of the framework relative to the size of the insulator chains, making it easy to pack and reducing packaging costs.

(Structure of the invention) The invention is made of a cushioning material such as cardboard or low-foaming synthetic resin, and is inserted between the cap fittings and the porcelain tsuba of the insulators, which are housed in opposite directions within the framework. It has a trapezoidal wave shape consisting of a contact surface and a connection surface that connects each contact surface to form a zigzag shape,
It is characterized by having a rigidity that allows it to maintain a constant shape unless an external force is applied to the bent portion that joins each contact surface and each connection surface,
The illustrated embodiment will be described in detail below.

The spacer shown in Fig. 1 is made of a cushioning material with a thickness of about 2 to 5 mm, which is made by laminating and compressing multiple sheets of cardboard made from waste paper sludge. Cap fittings 11 of double-row insulator chains 10 housed in opposite directions to each other.
and a contact surface 2 inserted between the porcelain collar 12 and the porcelain collar 12;
It is press-formed into a trapezoidal wave-like shape consisting of a zigzag-shaped connecting surface 3 that connects each of the contact surfaces 2. It is preferable to form slight irregularities 4 on each of these abutment surfaces 2 as shown in the figure to give them elasticity, and each bending portion 5 that joins each abutment surface 2 and each connection surface 3 to During pressure molding, a higher pressure is applied than other parts to give it greater rigidity than other parts. If high temperature and pressure are applied locally in this way, the synthetic resin components of magazine vinyl covers, etc., which are unavoidably mixed into the waste paper sludge, will act as an adhesive and only the bent portion 5 will become hard. The spacer can maintain a constant shape unless a large external force is applied, and the spacer can maintain a constant shape unless large external forces are applied.
This allows for easy insertion into the space. In addition to the above-mentioned materials, low-foaming synthetic resins may also be used as the material for the spacer, but cardboard made from waste paper sludge is advantageous in terms of manufacturing cost. Note that it is preferable that the entire cardboard is subjected to a waterproof treatment such as impregnation with paraffin so that it can withstand outdoor use.

As shown in FIG. 2, in this structure, a contact surface 2 is connected to a cap metal fitting 11 and a porcelain insulator between double rows of insulators 10 housed in opposite directions in a wooden framework 1. A connecting surface 3 located between the tsuba-making tsuba 12 and connecting each contact surface 2 to form a zigzag shape.
The insulator is inserted into the gap between adjacent porcelain flanges 12, and since it is entirely made of a cushioning material such as cardboard or low-foaming synthetic resin, the insulator may be damaged by vibration or impact during transportation. The impact load acting between the series 10 can be well absorbed and damage can be prevented, and the bent portions 5 that connect each contact surface 2 and each connection surface 3 maintain a constant shape unless external force is applied. Since it has a high rigidity that can be maintained, the overall trapezoidal wave shape is always maintained even though it is thin, improving the cushioning effect and making it easy to handle. As a result, when using the spacer of the present invention, the volume of the framework was reduced by 3 to 4% compared to when using a conventional spacer.
It can be made smaller, and loading efficiency can be improved when shipping.

(Effects of the invention) As is clear from the above explanation, the present invention is capable of reducing the volume of the framework relative to the size of the insulator chain, and is integrally molded into a predetermined shape. It is easy to insert and remove between spacers, reducing the number of man-hours required for packaging work, and can be produced at a lower cost than conventional wood board spacers, reducing packaging costs. As a spacer for packaging insulator chains that solves the problems of conventional double-row frame packaging for suspended insulator chains, its practical value is extremely great.
