基于扣压力的ω型弹条扣件作业机具校准测试台的研制

Research on Test Bed for Calibration of Operation Devices for ω- type elastic fastenings Based on Toe load of Fastening

基于对ω型弹条扣件作用于钢轨的扣压力检测,将其转换为旋紧扣件螺栓/螺母的扭矩,对作业机具的旋紧扭矩进行作业前和作业后校准,保证扣压力设置正确并具有较高的一致性,为高速铁路扣件系统养护作业提供一种简便有效的技术手段。

Based on testing of the toe load of the W-type elastic fastening acting on the rails,the toe load of fastening is converted to the torque for tightening the fastening＇ bolt / nut,the tightening torque of the operation device is calibrated before and after the operation. The toe load of fastening is ensured to be configured correctly and to be consistency. A simple and effective technical means is provided to maintain to the fastening system of high- speed railway.
