体を流れて作業者が感電する虞がある。However, when the vehicle is moved to the work site, the vehicle may pass through a point on the track. However, since the point is coated with grease, the vehicle is moved to the point. Grease adheres to the tread of the track running wheel, and the attached grease is peeled off from the tread by the ground brush and adheres to the ground brush. Then, grease gradually enters between the grounding brushes that come into contact with the treads, and there is a possibility that conduction between the grounding brushes and the treads may be interrupted. If the continuity is interrupted, the electric charge remaining on the trolley wire cannot be removed.In this state, when the worker gets on the vehicle body and performs maintenance and inspection work on the trolley wire, the remaining electric charge is removed from the trolley wire. Also, there is a possibility that the worker may get an electric shock by flowing through the body of the worker having a low potential.

問題が生じる。Also, the tread of the track running wheels is rough due to wear during running and uneven wear such as flat points, and when the ground brush contacts the rough tread, the ground brush is worn. Further, although the track running wheels are made of iron, even if the tread surface made of iron is polished, a projection having a sharply pointed tip is formed on the surface thereof. This causes a problem of further increasing the abrasion.

ラシ４５の耐久性をより向上させることができる。When the vehicle arrives at the work site, the operator gets on the work table 25 and performs a preparation operation. That is, a work device (not shown) provided on the work table 25 is brought into contact with a trolley wire (not shown) provided above the vehicle, and charges remaining on the trolley wire are caused to flow to the rail R, and the trolley wire, The body 3, the worker, and the rail R are set to the same potential. Here, FIG.
As shown in (a), since the conductive ring 43 provided on the iron ring 29 is provided on the left side surface of the iron ring main body 35a, an insulating material such as grease applied to the point portion of the rail R is applied to the iron ring 29. Even if it adheres to the tread surface 29a, the insulating material does not intervene between the conductive ring 43 and the tip of the ground brush 45, so that the conductive state between them can be maintained well. Also, since no external force other than the ground brush 45 acts on the surface 43a of the conductive ring 43, the surface 43a of the conductive ring 43 is maintained in a flat state, so that the wear amount of the ground brush 45 is reduced, and Can be improved in durability. Further, since the conductive ring 43 is made of a non-ferrous metal material, the conductive ring 43 made of a non-ferrous metal material is used.
When the surface 43a of the grounding brush 45 and the surface of the conductive ring made of iron are polished so as to have the same surface roughness, the amount of friction of the ground brush 45 contacting the surface 43a of the conductive ring 43 made of a non-ferrous metal material is smaller than that of iron. Can be smaller. Therefore, the amount of friction of the ground brush 45 is further reduced, and the durability of the ground brush 45 can be further improved.

Then, the potential between the trolley wire and the rail R can be made the same. For this reason, in the preparatory work and the maintenance and inspection work of the trolley wire, it is possible to prevent the worker from being electrically shocked beforehand.

５の左側に導電リング４３を設けた前述した例と同様の
作用及び効果を得ることができる。The material of the conductive ring 43 is gunmetal, but the material is not limited to this, and copper or carbon (C) can be used. In this case, for the ground brush 45, a conductive material having a hardness lower than that of copper or carbon (C) is selected. With this configuration, the iron wheel main body 3
The same operation and effect as in the above-described example in which the conductive ring 43 is provided on the left side of 5 can be obtained.

Even if the insulating material adheres to the tread of the track running wheel, the insulating material does not intervene between the conductive ring and the grounding member, and the conductive state between the two can be maintained. Further, since a large external force does not act on the side surface of the track running wheel, the surface of the conductive ring can be maintained in a flat state, the amount of wear of the ground member contacting the surface of the conductive ring can be suppressed, and the ground member can be reduced. Can be improved in durability. Further, the grounding member is urged toward the conductive ring by the urging means, so that even when the shape of the grounding member is deformed due to wear, the grounding member can be kept in contact with the conductive ring. Thus, the vehicle body and the rail can always be electrically connected.
