Foreign material removing device of track turnout portion

A foreign material removing device of a track turnout portion which comprises a stock rail of the track turnout portion, and a point rail that can move to contact and move away from the stock rail, and which removes a foreign material dropped between the stock rail and the point rail, the foreign material removing device comprising:

• a piping unit which includes a plurality of nozzle portions which spray compressed air to remove the foreign material, and
• a close-contact arrangement structure including a fixing member that presses against a concave portion of a lateral surface of the stock rail opposed to the point rail, wherein
• the piping unit presses against the fixing member with the fixing member elastically deforming with respect to the concave portion of the lateral surface of the stock rail opposed to the point rail in a state where the piping unit presses against the concave portion of the lateral surface, and
• the close-contact arrangement structure comprises a structure whose angle from a horizontal plane of a surface of the piping unit opposed to the concave portion of the lateral surface is an acute angle toward the concave portion of the lateral surface.

A foreign material removing device of a track turnout portion which comprises a stock rail of the track turnout portion, and a point rail that can move to contact and move away from the stock rail, and which removes a foreign material dropped between the stock rail and the point rail, the foreign material removing device comprising:

• a piping unit disposed in an area between the stock rail and the point rail, wherein
• a fixing member that supports the piping unit is disposed at a belly portion of a lateral surface of the stock rail, and the fixing member is formed of an elastic member,
• the stock rail includes a first leg portion and a second leg portion, the first leg portion and the second leg portion being provided below the belly portion,
• a first fixing member is disposed along the first leg portion and the second leg portion of the stock rail below the stock rail,
• the first fixing member is movable in a horizontal direction along the first leg portion and the second leg portion of the stock rail,
• a second fixing member having a tapered surface formed at a lower surface of the second fixing member is disposed at one end of the first fixing member, and a fixing portion for accommodating the second leg portion is provided at the other end of the first fixing member, and
• one of the leg portions of the stock rail is disposed between the second fixing member and the one end of the first fixing member, the second fixing member is fastened to the first fixing member to sandwich the one of the leg portions of the stock rail between the one end of the first fixing member and the tapered surface of the second fixing member, and the fixing portion is moved toward the stock rail to bring the piping unit into close contact with a side of the stock rail in a state where the piping unit presses against the belly portion of the stock rail.
