由郑州铁路局郑州计量所和浙江宁波鄞县东海仪表厂共同研制的“TCG-1型铁路线路超高测量仪”于1992年11月18日通过郑州铁路局技术鉴定。铁道部标准计量所,沈阳、广州、郑州铁路局,南昌铁路分局等10多个单位从事计量管理和工务工作的20余名专家出席了会议。该测量仪是用来测量铁路线路上两条钢轨之间的水平程度的专用仪器,由摆锤、杠杆、杠杆调节机构、齿轮、指针、表盘、外壳、表盖等组成。其工作原理是,由摆锤驱动,通过杠杆、齿轮传动,将线路水平和超高的情况由指针在刻度盘上指示出其数值。此仪器安装在轨距尺上,其操作机构与轨距尺的操作把手联动,当操作轨
Zhengzhou Railway Bureau by Zhengzhou and Ningbo, Zhejiang Yinhai East China Sea Instrument Factory co-developed “TCG-1-type railway line ultra-high measuring instrument” on November 18, 1992 Zhengzhou Railway Bureau by the technical appraisal. More than 20 experts engaged in metrological management and public works were present at the Metrological Standards Institute of the Ministry of Railways, Shenyang, Guangzhou, Zhengzhou Railway Bureau and Nanchang Railway Branch. The measuring instrument is used to measure the level of the two rails on the railway line between the special equipment, the pendulum, lever, lever adjustment mechanism, gears, hands, dial, shell, cover and other components. Its working principle is driven by the pendulum, through the lever, gear drive, the line level and high conditions by the pointer on the dial indicate its value. This instrument is mounted on the rail gauge ruler, the operating mechanism and rail gauge operation handle linkage, when the operating rail
