Description

  The present invention relates to a train wire material polishing apparatus for polishing a surface of a train wire material.

  In an electric railway, in order to supply electric power to an electric vehicle, an electric wire (train line) is provided along the track on which the electric vehicle travels, and a support (train line equipment) that supports the electric train is provided. It is provided along this train track. In such a train line facility, ears such as a T-T connector and an M-T connector are used as metal fittings for flowing current. For example, a TT connector electrically connects a trolley wire that slides a current collector of an electric vehicle and supplies load current to the electric vehicle, and an MT connector connects a trolley wire that suspends the trolley wire and the trolley wire. And are electrically connected.

  The surface of the trolley wire is a clean surface state having conductivity when new. However, as the aging progresses and corrosion occurs on the surface of the trolley wire, the resistance becomes high and current does not flow easily. Therefore, the trolley wire must be polished to improve the conductivity. In addition, when replacing the connector, the surface of the trolley wire must be polished when a new connector is attached to the corroded trolley wire. Conventionally, an operator uses a wire brush to manually polish a trolley wire, which requires a large amount of work, takes time, and reduces work efficiency. In order to reduce such a manual trolley wire polishing operation, a trolley wire polishing apparatus has been proposed.

  A conventional trolley wire polishing apparatus includes a wire brush that removes deposits attached to the surface of the trolley wire, a brush rotation motor that rotationally drives the wire brush, and a frame that supports the wire brush and the brush rotation motor. A cable pulley that rotates along the trolley line in a state where the frame is suspended from the trolley line, a travel motor that rotates the cable pulley, and the like are provided (for example, see Patent Document 1). In such a conventional trolley wire polishing apparatus, the frame is moved along the trolley wire by rotationally driving the cable pulley by the traveling motor, and the wire brush is rotated by the brush rotating motor to thereby remove the surface of the trolley wire. The deposit is scraped off by this wire brush.
