<p>PROBLEM TO BE SOLVED: To correctly grasp the relative position of rails, thereby allowing high accurate maintenance and inspection work, by providing a guide wheel for holding the relative position relation between a maintenance and inspection device for a rail and the rail, constantly always during travel concurrently to right and left rails. SOLUTION: In this rail work vehicle, a right and left pair of guide wheels 11 are provided on a truck 1 supported by a track wheel 2, and are provided with energizing means 4 and 10 being guided by horizontal guides 6 in a direction orthogonal to the rail, movable in right and left and vertical directions, and energizing the wheels 11 downward and outward, in addition are pivotally mouted rotation freely and independently on a wheel 12 tilted in a direction for heightening the outer side, and the outer perpheral surface 11c of the wheels 11 and flange inner surface 11b in the contact part with the rail are formed horizontal and vertical in the tilted condition. Consequently the ralative positional relation between the rail 15 and a maintenance and inspection device can be held constantly, thereby efficirntly performing maintenance and inspection work correctly.</p> |
