And a deburring blade having a shape following the shape of the lower peripheral surface of the trolley wire is disposed behind the wire brush.

According to the trolley wire deburring apparatus of the present invention, a wire brush arranged opposite to each other so as to form a V-shape with the trolley wire interposed therebetween raises the protruding burrs greatly, thereby moving the trolley wire backward. In addition to being able to be guided accurately to the disposed deburring blade, the remaining burr can be reliably removed by the deburring blade. Also, the deburring blade
Since it is formed in a shape following the shape of the lower outer peripheral surface of the trolley wire, only burrs adhered to the trolley wire can be reliably removed.

In this case, a cylindrical brush body can be used as the wire brush.

Thus, the trolley wire can be smoothly guided into the V-shaped groove formed by the wire brush, and the brush body of the wire brush has required functions such as abrasion, dirt, and the like to cause burrs. When the brush can no longer be used, by rotating the brush style at a required angle, for example, 90 °, the required function can be performed without replacing the brush body for a long period of time.

In this case, the outer peripheral portion of the deburring table can be covered with a dust collection cover connected to the suction device.

Thus, the burrs removed by the wire brush and the deburring blade can be collected by the suction device through the dust collecting cover.
