Post-welding working edge grinding method for side grinding steel rail thermit welding head
The invention discloses a post-welding working edge grinding method for a side-ground steel rail thermit welding head, which is characterized in that for two to-be-welded steel rails, a rail with relatively light side grinding degree or a new rail is a rail 1, a rail with relatively serious side grinding degree is a rail 2, and the rail 1 and the rail 2 are aligned by adopting a non-working edge alignment mode before thermit welding; the method comprises the following steps: I, measuring the arching amount of one side of a non-working edge of a rail 1; iI, determining the grinding length and depth of the working edge of the rail 1; iII, grinding a joint and a near-end steel rail of the rail 1; iV, polishing a steel rail at the far end of the rail 1; v, determining the grinding effect of the rail 1; and VI, polishing the working edge of the rail 2. In order to facilitate on-site first-aid repair, the invention further provides a side grinding steel rail working edge grinding quick look-up table. According to the method, post-welding working edge grinding data support is provided for the thermit welding joint under different side grinding conditions, and the method has important significance in reducing the operation difficulty, standardizing field operation, improving the post-welding joint quality and improving the smoothness of the steel rail working edge.
本发明公开了一种侧磨钢轨铝热焊接头焊后工作边打磨方法，其中待焊接的两根钢轨，侧磨程度相对轻的或者新轨为轨1，侧磨程度相对严重的为轨2，铝热焊接前轨1和轨2采用非工作边对齐方式对正；所述方法包括如下步骤：I.测量轨1非工作边一侧起拱量；II.确定轨1工作边的打磨长度及深度；III.打磨接头及轨1近端钢轨；IV.打磨轨1远端钢轨；V.确定轨1打磨效果；VI.打磨轨2的工作边。为便于现场抢修，本发明还提供了侧磨钢轨工作边打磨速查表。本发明的方法为不同侧磨情况下的铝热焊接头提供焊后工作边打磨数据支撑，对降低作业难度，规范现场作业、提高焊后接头质量、提高钢轨工作边平顺性都有重要意义。
