Alternating side grinding method for high-speed railway
The invention relates to a high-speed railway alternate side grinding method, which comprises the following steps of: 1, according to the characteristics of alternate side grinding, carrying out steel rail profile acquisition on a starting position, a quarter position, a midpoint, a three-quarter position and an ending position in a half cycle; and 2, according to profile comparison, the maximum polishing amount is reduced by 0.1 mm to serve as the on-site implementation polishing amount, and the small machine polishing target profile and the polishing range are determined. And 2, small machine grinding is conducted according to the determined subtotal grinding range, the profile of the steel rail is ground to a small machine grinding target profile, and it is ensured that the difference between the front profile and the rear profile of the ground steel rail is controlled within the range of +/-0.2 mm. And 3, the large machine is adopted for conducting secondary repairing on the steel rail profile, the steel rail profile is polished to be the steel rail profile without the front and back alternating side grinding sections, and therefore the consistency and smoothness of the steel rail profile are guaranteed.
本发明涉及一种高速铁路交替侧磨打磨方法，步骤1：根据交替侧磨的特性，对半周期内起始位置、四分之一位置、中点、四分之三位置、终止位置进行钢轨廓形采集。步骤2：根据廓形对比以最大打磨量减0.1mm为现场实施打磨量，并确定小机打磨目标廓形和打磨范围。步骤2：根据确定好的小计打磨范围，进行小机打磨，将钢轨廓形打磨至小机打磨目标廓形，确保打磨后钢轨前后廓形差异控制在±0.2mm范围内。步骤3：采用大机对钢轨廓形进行二次修复，将钢轨廓形打磨至前后无交替侧磨区段的钢轨廓形，以保证钢轨廓形的一致性和平顺性。
