Embodiment 3
[0079] An embodiment of the method for grinding the arc surface of the rail of the present invention specifically comprises the following steps:
[0080] Several rail grinding units 100 are longitudinally installed on the frame 300 of the rail grinding trolley 200, and the rail grinding unit 100 is adjusted to a set lateral position and inclination angle, and the outer circumference of the grinding wheel 9 faces the rail head of the rail 23 for sanding. The working surface of the grinding wheel 9 of each rail grinding unit 100 corresponds to a section of the arc surface of the rail head cross section of the rail 23, and the enveloping of the entire grinding section of the rail head 23 on one side is achieved through the combination of the grinding wheel 9 .
[0081] as attached Figure 13 As shown, in this embodiment, the top arc surface of the rail 23 is divided into five sections of arc surfaces, which are R300 in the middle, R80 on both sides and R13 near the rail head. T...
