既有的D08-32型自动抄平起拨道捣固车和D09-32型连续式捣固车的作业精度不能满足客运专线对轨道几何精度的要求。通过研制适合高速线路需要的、具备“长弦测量”特点和“起拨道自动跟踪”功能的“二维激光准直系统”,增加了捣固车的作业功能,其激光跟踪装置提供的准确“前端起道量及拨道量偏差输入值”,较好地消除了捣固车作业的“残余误差”。采用光电测量替代机械式测量方法,能够避免测量系统元件在捣固作业时受机械振动的影响。通过实验室的试验、实尺模拟测试和捣固车试装车试验的对比测试结果证明,光电测量系统的工作原理可行,其数据采集系统与捣固车控制系统的兼容性好,输出的数据可以满足捣固车的作业需要。
The existing D08-32 automatic copying flat from the tamper car and D09-32 type continuous tamper car operating accuracy can not meet the requirements of passenger rail line geometry accuracy. Through the development of the “two-dimensional laser alignment system” that is suitable for high-speed lines and has the characteristics of “long-chord measurement” and “automatic track-following”, the operation function of the tamping car is increased. The accuracy provided by the laser tracking device “The front-end starting volume and the amount of deviation dial input value”, eliminating the tamping operation of the “residual error.” The use of optoelectronic measurement instead of mechanical measurement methods, to avoid the impact of mechanical vibration when measuring system components in the tamping operation. Through laboratory tests, real-scale simulation test and tamping test vehicle loading test test results show that the working principle of optical measurement system is feasible, the data acquisition system and tamper control system compatibility, the output data Tamping car to meet the operational needs.
