大尺寸测量设备高空精测平台的研制

Development of High Altitude Precision Measuring Platform for Large-scale Measurement Equipment

结合大型精密系统部装及总装精测时对大尺寸测量设备布局优化及稳定性的要求,论述了大尺寸测量设备高空精测平台结构组成、实现设备高空精测时的稳定支撑方式、稳定升降的结构原理。试验数据表明,该平台高空作业时沉降率不大于0. 02 mm/h,加载经纬仪稳定性达到0. 6″/h,满足精测需求。

Combining the requirements of layout optimization and stability of large-size measuring equipment during precision measurement of large-scale precision systems,this paper expounds the structure principle and realization method of stable lifting of large-scale precision measuring platform.Finally,with the help of the omni-directional transfer platform and the carbon fiber synchronous lifting system,the stable support and automatic walking of the large-size measuring device at high altitude are realized.The experimental data show that the stability of the platform is better than that of the theodolite.
