CONFIRMATION TOOL FOR CONTACT POSITION BETWEEN RAIL AND WHEEL
PROBLEM TO BE SOLVED: To provide a tool for readily confirming a contact position between a wheel and a rail corrected by grinding of a railway, at a site of the grinding work.SOLUTION: A tool (1) is for confirming a contact position between rails (2A, 2B) installed in parallel to each other and a wheel in contact respectively with the rails (2a, 2B). The tool (1) includes wheel simulation parts (11A, 11B) and a connection part (12). The wheel simulation part (11A) includes a surface for contacting with the rail (2A). The surface has a contour that is the same with a contour of a tread and a flange of a cross-section through an axial center of the wheel, when seen from a direction of extension of the rail (2A). The wheel simulation part (11B) includes a surface for contacting with the rail (2B). The surface has a contour that is the same with a contour of a tread and a flange of a cross-section through the axial center of the wheel, when seen from the direction of extension of the rail (2B). The connection part (12) extends in a width direction of a track. The connection part (12) is connected between the wheel simulation parts (11A, 11B).SELECTED DRAWING: Figure 1
【課題】鉄道において、車輪と削正されたレールとの接触位置を削正現場で容易に確認することができる器具を提供する。【解決手段】器具（１）は、鉄道において、並列に配置されたレール（２Ａ，２Ｂ）と、レール（２Ａ，２Ｂ）にそれぞれ接触する車輪との接触位置を確認するための器具である。器具（１）は、車輪模擬部（１１Ａ，１１Ｂ）と、連結部（１２）とを備える。車輪模擬部（１１Ａ）は、レール（２Ａ）に接触するための表面を含む。当該表面は、レール（２Ａ）が延びる方向から見て、車輪の軸中心を通る断面における踏面及びフランジの輪郭と同じ輪郭を有する。車輪模擬部（１１Ｂ）は、レール（２Ｂ）に接触するための表面を含む。当該表面は、レール（２Ｂ）が延びる方向から見て、車輪の軸中心を通る断面における踏面及びフランジの輪郭と同じ輪郭を有する。連結部（１２）は、軌道幅方向に延びる。連結部（１２）は、車輪模擬部（１１Ａ，１１Ｂ）の間に連結される。【選択図】図１
