| 摘 要： | 天线座是70 m大型射电望远镜天线现场安装的重点和难点。考虑现场安装的周期以及所使用的吊车，先对天线座架进行拼装，然后并行拼装俯仰框架十字与俯仰扇齿组合，最后将俯仰框架整体吊装至天线座架。拼装过程中使用高精度激光跟踪仪、电子水准仪、全站仪等仪器对安装指标进行实时检测和调整，最终，天线座所有指标符合设计要求。经实际使用，天线接收信号正常，为超大型射电望远镜天线座的安装提供了宝贵经验。

| Abstract: | The antenna pedestal is the key and difficult point of field installation of 70 m antenna of large radio telescope. Considering the period of field installation and the crane used, the antenna pedestal frame is assembled first, then the cross-shaped elevation truss and the elevation gear combination are assembled in parallel, and finally the overall elevation truss structure is hoisted on the antenna pedestal frame. In the assembly process, the high-precision laser tracker, electronic level, total station and other instruments are used to measure and adjust the installation indicators in real time, and finally all antenna pedestal indicators meet the design requirements. After practical use, the antenna received signal is normal, which provides valuable experience for the installation of super large antenna pedestal. |
