この場合、上記繊維はコンベアチェンが走行する方向、
即ち張力がかかる方向に整列しているので、リンクは優
れた抗張力を有し、しかも継目がないので破断する虞れ
もない。In this case, the fibers are the direction in which the conveyor chain travels,
That is, since the links are aligned in the direction in which tension is applied, the links have excellent tensile strength, and there is no risk of breaking because they are seamless.
さらにまた、この考案になるチェンのリンクは炭素繊維
または無機繊維で作られているので、2000℃以上、3000
℃までもの雰囲気下で使用し得る卓越した効果がある。Furthermore, since the chain link of this invention is made of carbon fiber or inorganic fiber, it is more than 2000 ℃, 3000
It has an outstanding effect that it can be used in an atmosphere up to ℃.
この考案の好適な一実施例を、以下に添付図面を参照し
ながら説明する。A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.
（ニ）実施例 まず第１図に示すように、径30mmの断面が円形の型４上
に径約６〜10μｍの炭素繊維２を該型４の軸を横切る方
向で厚み約1mmになるように連続して捲回した。(D) Example First, as shown in FIG. 1, a carbon fiber 2 having a diameter of about 6 to 10 μm was placed on a mold 4 having a diameter of 30 mm and a circular cross section so that the thickness was about 1 mm in a direction crossing the axis of the mold 4. It was wound continuously.
そして、この捲回した炭素繊維群の上に溶剤で薄めたピ
ッチ系接着剤を塗付し、繊維どうしを固着した。かくし
て作られた炭素繊維２の円筒を離型し、150℃で４時間
焼付けた。この円筒をその軸を横切る方向に沿って厚み
3mmで順次に切断して、多数の円環状のリンク１を得
た。この円環状リンク１を径4mmの連結杆５で支持され
るような細長環状のリンク１′にした（第３図参照）。Then, a pitch-based adhesive diluted with a solvent was applied onto the wound carbon fiber group to fix the fibers together. The cylinder of carbon fiber 2 thus produced was released from the mold and baked at 150 ° C. for 4 hours. The thickness of this cylinder along the direction transverse to its axis
The pieces were sequentially cut at 3 mm to obtain a large number of annular links 1. This annular link 1 is made into an elongated annular link 1'supported by a connecting rod 5 having a diameter of 4 mm (see FIG. 3).
かくして得られた多数のリンク１′を第５図にて図示さ
れるように、同じく炭素繊維或は無機繊維でつくられた
連結杆５でつないだ。連結杆５のそれぞれの解放端に
は、同じく炭素繊維或は無機繊維でつくられたナットを
接着剤で固定した。The multiple links 1'obtained in this way are connected by connecting rods 5 also made of carbon fibers or inorganic fibers, as shown in FIG. A nut, also made of carbon fiber or inorganic fiber, was fixed to each open end of the connecting rod 5 with an adhesive.
このようにして、本考案になるコンベアチェンは構成さ
れるが、必要によっては図中に符号３で示される間隔保
持体を使うこともできる。この間隔保持体３は、コンベ
アチェンが収納あるいは運搬時等にあって緊張下におか
れていないときに、連結杆５がリンク１′の内方両側端
でない位置に移動してコンベアチェン全体がぐちゃぐち
ゃなマス状になるのを防ぐためである。In this way, the conveyor chain according to the present invention is constructed, but if necessary, the spacing holder indicated by reference numeral 3 in the drawing can be used. The spacing holder 3 moves to a position where the connecting rods 5 are not inside both ends of the link 1'when the conveyor chain is stored or transported and is not under tension, and the entire conveyor chain is This is to prevent it from becoming a messy mass.
この間隔保持体３は、リンク１′を中心に所定回数よじ
り、その中心のよじった個所をピッチ系接着剤等の接着
剤で固着，固定したものであり、コンベアチェンに組込
まれたときに張力が働く方向に整列した炭素繊維２でで
きている。The space holder 3 is twisted about the link 1'a predetermined number of times, and the twisted portion of the center is fixed and fixed with an adhesive such as a pitch-based adhesive. Made of carbon fibers 2 aligned in the direction in which
このようにしてなるコンベアチェンを長さ7mの2500℃の
不活性雰囲気の連続炉中を循環するように運転したとこ
ろ、円滑な運転が長時間にわたって保証され、張力も充
分であった。When the conveyor chain thus formed was operated so as to circulate in a continuous furnace having a length of 7 m and an inert atmosphere of 2500 ° C., smooth operation was assured for a long time, and the tension was sufficient.
（ホ）考案の効果 本考案によれば、上記実施例で述べた卓越した効果があ

い。(E) Effect of the device According to the device of the present invention, in addition to the excellent effect described in the above embodiment, it is necessary to perform work such as welding both ends of the carbon steel link unlike the conventional carbon steel links. In addition, manufacturing cost can be kept low and quality control is easy. By the way, the service temperature of conventional tensile strength steel is only 1100 ° C, and its tensile strength is only about 1/5 that of carbon fiber.
