  • THIRD EMBODIMENT A third embodiment will now be described with reference to FIGS. 9 through 14.
  • a framework 106 supporting an abrasive-slinging device 107 spans the space between the sleepers 103A and 1038 and is arranged to be movable back and forth in the lengthwise direction A of the lounges 103A and 1038 with the sleepers 103A and 1038 serving as guides.
  • the framework 106 is constructed by assembling transverse pipes 108 and longitudinal pipes 109, and has a traveling motor base 110 fixed on one side thereof and a roller support plate 111 fixed on the other side. Rollers 112 riding on one sleeper 103A are journaled on the motor traveling base 110 and a roller 113 riding on the other sleeper 1038 is journaled on the roller support plate 111.
  • Rollers 122a and 122b which engage one sleeper 103A are provided on one side of the framework 106. That is, a pair of front and back rollers 122 are disposed outside the traveling motor base 110 and abut against the outer surface 103a of the sleeper 103A, while a single roller 122b is disposed inside the traveling motor base 110 and abuts against the inner surface 103a of the sleeper 103A. These rollers engage the sleeper 103A in such a manner that their center distances form an isosceles triangle.
  • rollers 122a and 122b are attached to the transverse pipes 108 through joints 123a and 123b which are capable of being tightened and loosened, so that they can be moved toward and away from each other in the lengthwise direction of the transverse pipes 108.
  • An abrasive-slinging device 107 is supported on a base 124 attached to the middle portion of the framework 106.
  • the base 124 is attached to the lower ends of four vertical pipes 126 liftable with respect to joints 125 attached to the transverse pipes 108, said joints 125 being movable lengthwise of the transverse pipes 108. Therefore, the base 124 for the abrasive-slinging device 107 is liftable with respect to the framework 106 and movable widthwise (or transversely) of the framwork. Further, the abrasive-slinging device 107 is fixed to the lower end of a vertical shaft 127 rotatably attached to the base 124, so that the device is rotatable around the vertical axis 127a.
