To reduce the weight and size of a lifting mechanism part as a whole without using a heavy one so as to reduce labor at the time of transportation and installation on site.SOLUTION: A hand-push rail reprofiling device is provided with a truck body 11, a rail reprofiling part 12 rotatably connected to the truck body 11 via a first rotary shaft 11f extending in a direction perpendicular to the longitudinal direction of a rail R so that a grinding belt 12h passed between a grinding belt driving roller 12f and a grinding belt driven roller 12g is rotated by the driving source 12a such as an engine or a motor to reprofile a surface of the rail R, and a lifting mechanism part 13 for rotatably moving the rail reprofiling part 12 up and down with respect to the truck body 11 via the first rotating shaft 11f. The rail reprofiling part 12 is provided with a belt pressing plate 12j that presses the grinding belt 12h against the rail R between the grinding belt driving roller 12f and the grinding belt driven roller 12g, the pressing plate 12j being swingably provided via a swing shaft 12i11 extending parallel to the first rotation shaft 11f.SELECTED DRAWING: Figure 1
【課題】重量のある昇降機構部は使用せずに全体として軽量かつ小型化して、運搬や現場設置の際の人手を削減する。【解決手段】台車本体１１と、台車本体１１に対しレールＲの長手方向に対し垂直方向に延びる第１回動軸１１ｆを介し回動可能に連結され、エンジンやモータ等の駆動源１２ａによって研削ベルト用駆動ローラ１２ｆと研削ベルト用従動ローラ１２ｇとの間に渡された研削ベルト１２ｈを回転させてレールＲ表面を削正するレール削正部１２と、台車本体１１に対し第１回動軸１１ｆを介してレール削正部１２を上下方向に回動して昇降させる昇降機構部１３とを備え、レール削正部１２には、研削ベルト用駆動ローラ１２ｆと研削ベルト用従動ローラ１２ｇとの間で研削ベルト１２ｈをレールＲに対し研削ベルトを押当てるベルト押当て板１２ｊを設け、ベルト押当て板１２ｊは第１回動軸１１ｆと平行に延びる揺動軸１２ｉ１１を介し揺動可能に設ける。【選択図】図１
