引き留めるための引留杆に関するものである。[Detailed description of the invention] The present invention is a restraining device for retaining a curved trigger, which is used to maintain the deflection of overhead contact lines and auxiliary suspension wires, to an insulator attached to a structure in a curved section of a railway track. It concerns the rod.

欠点がある。 A conventional curved trigger H is fastened to an insulator I by a wire R, as shown in FIG. During the installation work, the wire R
In addition to determining the length of the insulator I, it is necessary to form an eye portion E at the end thereof for connection to the clevis C of the insulator I. This eye portion E is formed by folding back the end of the wire R to form a loop, and wrapping the wire W around the loop, which is a so-called pipe winding process. This work is difficult, time consuming, and requires skill. In addition, in places where the rail has a large radius of curvature, such as a siding inside a station, the hold wire tends to sag once installed, and this sagging makes it impossible to obtain the specified angle of inclination of the curved trigger, causing the curved trigger to sag. There is a risk of pantograph collision. However, it is not possible to adjust the slackness of the anchoring wire to eliminate this slack.
There is a drawback that it must be replaced with a new one each time.

できるようにしたことを特徴とするものである。 In view of the above-mentioned drawbacks of the conventional curved trigger retaining wire, the present invention has been devised to solve these problems.The present invention replaces the retaining wire with a rod-shaped one, and further divides the wire into at least two parts so that they can be connected to each other. It is characterized by being able to be connected freely by expansion and contraction, and also by being easily attached to an insulator.
