To supply power. At this time, wear of the brush 102 in contact with the trolley 101 is generated. When the excessively worn brush 102 is used as it is without being replaced, the shoe 102 and the tortoli 101 are directly connected to each other. Since it causes equipment accidents that cause abnormalities in contact with the power supply, the operator must check the wear degree of the brush 102 from time to time to replace it with a new one.

However, in the case of a facility directly connected to a production line, since the power supplied to the trolley 101 cannot be cut off, it is difficult to check the degree of wear of the brush 102. The amount of wear of the brush 102 was measured from the side. Accordingly, there is a significant error in confirming the actual amount of wear of the brush 102, so that the case of missing the appropriate replacement cycle frequently occurs, causing problems with equipment and safety accidents.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which has a ruler that can perform a timely brush replacement by accurately measuring the actual wear amount of the brush even while the brush is in contact with the trolley We want to provide a fantagraph.
