Device for correcting ruggedness of welded joint of rail by cutting
专利汇可以提供Device for correcting ruggedness of welded joint of rail by cutting专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the vibration of train, by correcting the ruggedness of welded joint of rail due to the depth of recess of the rail by approximate sine curve cutting.
CONSTITUTION: A truck 1 is stopped so that the welded part is located at the center of guide rails 7. Wheels 5 are elevated and the guide rails 7 and lamps 3 are placed on the corrected rail 2. The ratation of a hydraulic motor 11 is transmitted and speed-reduced by gears 12W15 to move a cutter 8 on the guide rails 7. A crank plate 22 performs one rotation while the cutter 8 is moved from one end to another. The circular motion of the crank plate 22 is converted into straight reciprocating motion to move a cutting tool 9 up and down through a screw rod 30. The cutter 9 is moved down to a cutting position by a handle 33 and the hydraulic motor 11 is driven, thereby cutting the rugged part of the rail 2 along a smooth sine curve in one process.
