Description

【発明の詳細な説明】 この発明は長さ方向に鋼線が埋込まれたトロリ線いわゆ
る鋼心入りトロリ線の優れた製造方法に関する。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an excellent method for manufacturing a contact wire in which steel wire is embedded in the length direction, that is, a contact wire with a steel core.

トロリ線の引張強度を増大させるためやトロリ線の摩耗
量検知のためにトロリ線本体の内部に鋼線を埋込んだも
のが種々提案されているが、その大半はトロリ線の内部
にただ単に鋼線を埋込んだ構造である。
Various methods have been proposed in which steel wires are embedded inside the contact wire body in order to increase the tensile strength of the contact wire or to detect the wear amount of the contact wire, but most of them are simply embedded inside the contact wire. It has a structure with embedded steel wires.

このため摩耗量検知の役割は果たすことはできても十分
な補強の役割を果たすことはできない。
Therefore, although it can play the role of detecting the amount of wear, it cannot play the role of sufficient reinforcement.

リ線本体と鋼線との界面に摩擦力が作用しないためトロ

るまでの間鋼線が十分補強の役割を果たしていない。
In other words, if we consider the case where the contact wire breaks due to tensile load, if the structure is such that the steel wire is simply embedded, no frictional force will act on the interface between the contact wire main body and the steel wire, so the contact wire main body will break. The steel wire does not play a sufficient reinforcing role until the contact wire itself breaks because the breakage occurs individually.

てこの成形鋼トロリ線に形成せられる溝内にそれよりも
硬い鋼線を埋設するために充分な冶金的結合が得にくい

ければならないものである。
These contact wires are usually made of steel, and the main reason for this is that it is difficult to obtain a sufficient metallurgical bond to embed a harder steel wire in the groove formed in the formed steel contact wire. Now, this problem must be solved in manufacturing.

本発明は上記実情の元に鑑みて為されたものであって、

うとするのである。
The present invention has been made in view of the above circumstances, and
When inserting the steel wire, the steel wire and the contact wire main body are combined with hard particles having a grain size of about 120 mesh interposed in the presence of an adhesive, and the combined contact wire is inserted into the steel wire. The die drawing process is performed using a compressive force that is greater than the degree of processing required to form a close contact with the steel wire, thereby increasing the frictional force at the interface between the steel wire and the contact wire body, which is similar to a metallurgical bond, and thereby creating a sufficient bond between the steel wire and the contact wire. The aim is to have them play a reinforcing role.

According to the method of the present invention, no heating means is required;
It has the advantage of being able to maintain the material strength of the contact wire and steel wire at a high level, and while maintaining this strength, it is possible to achieve a connection due to the optical anchor effect. can provide the line.

アルミナ等が用いられる。
In the above, the hard particles interposed at the interface between the contact wire and the steel wire include carborundum, magnesia,
Alumina or the like is used.

鋼線としては多くの場合断面円形で表面も比較的平滑な

Steel wires often have a circular cross section and a relatively smooth surface.

その場合硬質粒体をそのまま用いたのでは、鋼線を受入
れるトロリ線側の溝形状にもよるが、硬質粒体が前記界
面に一様に分散されるようなことはほとんどあり得ない
In that case, if the hard particles are used as they are, it is almost impossible for the hard particles to be uniformly dispersed at the interface, although it depends on the shape of the groove on the contact wire side that receives the steel wire.

従って、この硬質粒体と前記界面との関係は接着剤を介
すか接着剤と混和して前記界面のうち何れか一方の面に
硬質粒体を位置させることが望ましいのである。
Therefore, the relationship between the hard particles and the interface is such that the hard particles are preferably positioned on one of the interfaces through an adhesive or by being mixed with an adhesive.

In FIG. 1, reference numeral 3 denotes a layer of hard particles 1, such as carborundum, interposed between the contact wire main body 1 and the steel wire 2. It is continuously deposited on a thin film of adhesive and fixed by air drying or heating the film of adhesive.

This layer 3 is also positioned by inserting the steel wire 2 into the groove of the small arc surface section 11 (or large arc surface section 12) of the contact wire main body 1 which has been preformed separately, and in this state, they are diced. The contact wire 1 and the steel wire are drawn by drawing the contact wire through the contact wire, covering the groove and the steel wire 2 with the contact wire main body, and compression-molding the contact wire main body 1 to a degree of processing that is greater than the degree of processing required to make the contact wire main body 1 adhere to the steel wire 2. It bites into both sides of 2 and holds both in a strong fixed state.

Therefore, if such a final structure is adopted, the contact wire main body 1 and the steel wire 2 will be firmly fixed together by the interposition of the hard particles 3, and the frictional force will be reinforced between the two, thereby effectively reducing the contact wire main body 1. Not only can the contact wire main body be reinforced, but also the amount of wear on the contact wire main body can be made uniform (even if the wear reaches the steel wire, the amount of wear in the longitudinal direction of the contact wire main body 1 is uniform).

In this case, the pulling force is a measure of the adhesion strength between the contact wire main body 1 and the steel wire 2. When the end face of the contact wire main body 1 is supported and the end face of the steel wire 2 is held and pulled, the contact wire It is expressed as the load until the steel wire 2 is pulled out from the main body 1, but according to these results, the pulling force reaches its maximum when the grain size is around 120 mesh, and the pulling force decreases even if the grain size is larger or smaller than this. I understand.

Therefore, it is desirable that the hard particles used have a particle size of around 120 mesh.
