Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting section of an insulating section, an end approach, etc. provided at the terminal of a rigid trolley used for overhead contact lines, contact wires, etc.

In this type of section, the section molded body is directly attached to one end of the rigid trolley with a connector, but when the current collector slider passes through the rigid trolley and the section molded body, the end of the rigid trolley is separated from the track. There is a tendency for arcing to occur on the sliding surface, causing roughness on the sliding surface and resulting in wear and tear.

For this reason, it is necessary to periodically replace the rigid trolley, but since the rigid trolley is heavy and relatively long, replacement work is difficult and uneconomical.

The present invention has been developed in view of the above circumstances, and its purpose is to provide an economical section connection that prevents wear and tear on the rigid trolley, simplifies maintenance and replacement, and is economical.

In other words, when connecting an insulating section or a section such as an end approach to the end of a rigid trolley having a substantially ■-shaped cross section, the section connecting portion of the present invention has a wear-resistant structure between the end of the rigid trolley and the section molded body. A relatively short intermediate conductor formed with an arc-resistant conductive sliding contact surface is interposed such that the wear-resistant and arc-resistant conductive sliding contact surface matches the sliding surface of the rigid trolley and the section molded body. In addition, the intermediate conductor is detachably connected to a connection plate that connects the rigid trolley and the section molded body.

The present invention will be explained below with reference to the drawings, in which T is a rigid trolley having a sliding surface T1, 1 is made of steel or synthetic resin, and is an end approach having an inclined sliding surface 1a, and a connecting plate 2 is connected to a bolt 3. are connected at.

4 is a relatively short intermediate conductor, which forms a conductive sliding surface 4a between the rigid trolley T and the end approach 1 that matches the sliding surfaces T1 and 1a, and is attached to the connecting plate 2 with a bolt 5. They are arranged consecutively.

A light metal molded body or the like is attached to the sliding surface 4a of the intermediate conductor 4 to provide a wear-resistant, arc-resistant conductive surface with a stainless steel plate 6 attached thereto.

At the insulating section connection part, the insulating section may be connected instead of the above-mentioned end approach.

Since the present invention is constructed in this manner, when the current collecting slide plate moves from the rigid trolley T to the section, it slides through the conductive sliding surface 4a of the intermediate conductor 4, so that the current collector slider slides through the conductive sliding surface 4a of the intermediate conductor 4, so that the current collector slider plate slides through the conductive sliding surface 4a of the intermediate conductor 4. Since the rigid trolley is protected by forcing an easy arc to occur on the sliding surface 4a, it is sufficient to replace the short intermediate conductor instead of replacing the heavy rigid trolley in the long term, which reduces the maintenance and replacement work. It is economically advantageous because it has a very good structure and the enclosed intermediate conductor can be manufactured at a lower cost than a rigid trolley, and its practical benefits are significant.
