  In the rail work machine, in order to cope with the difference in the rail interval of the railway, it is preferable to have a configuration in which the interval of the rail traveling wheels can be changed (having a gauge change function) in terms of enhancing versatility. For this reason, the rail traveling wheels are attached to the traveling body frame so that the left and right intervals can be changed. An example of such a gauge changing device is disclosed in Patent Document 1.

  In the track-and-rail work machine described in Patent Document 1, a frame is provided so as to be pivotable up and down before and after a traveling body frame for ground traveling, and a rail traveling wheel is provided on a lower surface of a horizontal frame included in the vertically moving frame. The bracket is provided with a flat plate-like upper plate portion and fixed to the horizontal frame with fastening bolts. Further, in order to support the bracket so that it does not fall during the change of the gauge, a long hole for guide is provided in the upper plate part, and the outer diameter wider than the width of the long hole is provided in the long hole. Bolts are inserted through the collar, and the bolts are fastened to the horizontal frame to hold the brackets to the horizontal frame, and the bracket is movable relative to the horizontal frame by the length of the long hole. ing.

Japanese Patent No. 3187491

  In the above-described conventional gauge change device for a track-and-rail work machine, a horizontal frame is configured by spanning a flat horizontal plate between a pair of left and right arms constituting a vertical motion frame. The horizontal plate requires a large width in order to secure the strength of the horizontal frame and fix the entire upper plate portion of the bracket in contact with each other, resulting in an increase in weight. In addition, in order to keep the bracket on the horizontal frame when changing the gauge, it is necessary to provide bolt holes and long holes in the upper plate of the horizontal plate and bracket, which increases the number of manufacturing steps and the number of parts. There was a problem that the cost increased.
