Method for repairing damaged steel rail
The invention relates to a method for repairing a damaged steel rail; the method comprises the following steps that: S1, flaw detection is carried out to find a damaged part of a steel rail or a welded joint; S2, holes are drilled in rail waists; S3, weld joints are polished and trimmed, and the inner surfaces of the to-be-bonded grooves of the steel rails and the gluing surfaces of the clamping plates are cleaned; S4, glue is applied; S5, gluing clamping plates are installed; S6, bolts sleeved with insulation sleeves are installed; S7, the bolts are tightened in sequence through a torque wrench; S8, the lower edges of the bolts are knocked, the bolts are tightened again through the torque wrench, and the step is repeated multiple times till the torsional moment of each bolt meets the requirement; and S9, the insulation resistance value between the steel rail and the clamping plate are detected to meet the requirement. The method has the following beneficial effects that when the bolts are installed, the bolts are sleeved with the insulation sleeves, so that the steel rails cannot be conducted with the clamping plates through the bolts; when the damaged part is fractured again, huge resistance can be generated between the two sides of the fractured part and detected by an existing detection means, so that workers can find the problem in time, and potential safety hazards are eliminated.
本发明涉及一种伤损钢轨修复方法，包括如下步骤：S1探伤发现钢轨或焊接接头伤损处；S2在轨腰上钻孔；S3打磨修整焊缝，清洁钢轨待粘接凹槽内表面以及夹板的胶合面；S4、涂刷胶水；S5安装胶合夹板；S6安装套设有绝缘套的螺栓；S7使用扭力扳手依次拧紧螺栓；S8敲击螺栓下沿，并再次用扭力扳手拧紧螺栓，重复本步骤多次直至每个螺栓的扭力矩达到要求；S9检测钢轨与夹板之间的绝缘电阻值达到要求。具有如下有益效果：本伤损钢轨修复方法在安装螺栓时，在螺栓外套设有绝缘套，使得钢轨无法通过螺栓与夹板导通；当伤损处再次断裂，断裂处两侧之间能够产生巨大的电阻，被现有的检测手段检测到，以便于工作人员及时发现，消除安全隐患。
