Claims (2)
- 平面視で軌道の延長方向に交差する横方向のまくらぎの変位を捉えてレール張出しを検知するレール張出し検知手段を備え、
前記レール張出し検知手段が、下端側を安定支持部に固定し、上端側を前記まくらぎの側端部に対して前記横方向に所定の間隔をあけてあるいは前記横方向に接触させてあるいは前記横方向に接続して配設され、
前記下端側と前記上端側との間に屈曲手段が設けられ、
前記まくらぎが前記横方向に変位するとともに前記上端側がこれに従動して変形しレール張出しを検知するように構成されていることを特徴とするレール張出し検知システム。 - 請求項1記載のレール張出し検知システムにおいて、
制御手段と警告手段とを備え、
前記レール張出し検知手段で検知したレール張出し量が閾値を超えるとともに、前記制御手段からの動作指令を受けて警告手段が警告を発するように構成されていることを特徴とするレール張出し検知システム。
