高速铁路道岔转辙设备机械、电气特性及测试检修
(一)机械特性测试项目、周期、标准及方法
1.测试项目及标准
(1)道岔外部检查
①道岔密贴检查:检查尖轨与基本轨、心轨与翼轨应达到静态宏观密贴。道岔锁闭后,用
塞尺插入检查尖轨尖端至第一牵引点处允许有≤0.5mm的间隙,其余部分允许有≤1mm间
隙。
②用1mm塞尺插入检查尖轨轨腰与顶铁间隙<1mm。
③道岔爬行检查:查看标尺,尖轨爬行≤20mm。
④吊板检查:用1mm塞尺能插入尖轨底部,说明该处吊板;尖轨吊板不能连续超过3块。
⑤销轴旷动量检查:通过塞尺检查连接面的磨痕来判断,表示杆销孔旷量≤0.5mm,其他
销孔旷量≤1mm。
⑥油管检查:油管、油管防护槽钢及主副机连接处所无油迹,油管弯曲半径≥150mm,油
管无较大龟裂,防护槽钢固定良好,油管出口处有防磨措施。
