TRACK GAUGE CORRECTION APPARATUS
PROBLEM TO BE SOLVED: To provide a track gauge correction apparatus capable of correcting a track gauge between rails, even when a gap cannot be secured between a rail bottom part and a sleeper top surface for inserting a rail catch part, or in a section with a derailment prevention guard installed between rails.SOLUTION: A track gauge correction apparatus includes a pair of rail catch parts 11, 11 that catches a pair of rails 2 respectively, and an expansion/contraction mechanism 12 having each of the rail catch parts 11, 11 disposed on fitted parts 12a, 12a on both sides, for expanding/contracting a distance between the rail catch parts 11, 11. Each of the rail catch parts 11, 11 includes a head part catch part 11a that catches a head part 2a of each rail 2, a web part catch part 11b that catches a web part 2b of each rail 2, and a bottom part catch part 11c that catches a bottom part 2c of each rail 2. Any one of the catch parts 11a to 11c may be fitted selectively and replaceably on both sides of the expansion/contraction mechanism 12.SELECTED DRAWING: Figure 1
【課題】レール底部とマクラギ上面との間にレールキャッチ部を通す間隔を確保できない場合や、レール間に脱線防止ガードが設けられている区間でも、レールの軌間整正を行うことができる軌間整正器を提供すること。【解決手段】一対のレール２それぞれをキャッチする一対のレールキャッチ部１１，１１と、両側の被取付け部１２ａ,１２ａにそれぞれ各レールキャッチ部１１，１１が設けられ、各レールキャッチ部１１，１１の間隔を伸縮させる伸縮機構部１２とを備え、各レールキャッチ部１１，１１は、各レール２の頭部２ａをキャッチする頭部用キャッチ部１１ａと、各レール２の腹部２ｂをキャッチする腹部用キャッチ部１１ｂと、各レール２の底部２ｃをキャッチする底部用キャッチ部１１ｃとを有し、これらキャッチ部１１ａ〜１１ｃのいずれか一つを伸縮機構部１２の両側に選択的かつ交換可能に装着できるように構成した。【選択図】図１
