本文针对枕轨用液压螺栓扭矩扳手测控的不足,提出了一种通过扭矩传感器直接测量扭矩扳手旋转扭矩方式来控制扭矩的测控方案。基于该方案,对测控系统的软件、硬件系统进行了研究和设计。样机测试结果表明:该系统扭矩控制精度高,加载平稳、快速,作业效率高。
In this paper, aiming at the shortcomings of the measurement and control of the hydraulic bolt torque wrench on the rail, a measurement and control scheme of controlling the torque by measuring the torque wrench torque directly by the torque sensor is proposed. Based on the scheme, the software and hardware system of the measurement and control system are researched and designed. The prototype test results show that the system has high torque control accuracy, stable loading, fast operation and high work efficiency.
