Description
技术领域technical field
本实用新型涉及测量装置领域，具体涉及到一种基座式对中杆测量装置组件。The utility model relates to the field of measuring devices, in particular to a base type centering rod measuring device assembly.
背景技术Background technique
在测绘行业中，对中杆的优势在于装置简易便于安放、可伸缩性好，为全站仪的测量提供了很好的通视条件。但对中杆的整平仅以圆水准泡为准，这样会带来目标点的偏心误差，如在一些运营期间的大桥等的监测过程中，由于桥面的晃动，对中杆的不稳定性会增加，且圆水准泡的偏心也不易发现，无法达到高精度测量的目的。而对于常用的精密基座棱镜装置，精密基座带有圆水准泡和管水准气泡，很大程度上避免了因目标点的晃动和不稳定性带来的偏心误差，增加了测量的稳定性。但这种装置的缺点在于精密基座不可伸缩，受地形和现场环境限制大，影响全站仪的通视。In the surveying and mapping industry, the advantages of the centering rod are that the device is simple and easy to install, and has good scalability, which provides good conditions for the total station to measure. However, the leveling of the centering rod is only based on the circular vial, which will cause the eccentricity error of the target point. For example, during the monitoring of some bridges during operation, the centering rod is unstable due to the shaking of the bridge deck. The stability will increase, and the eccentricity of the circular vial is not easy to find, and the purpose of high-precision measurement cannot be achieved. For the commonly used precision base prism device, the precision base is equipped with circular vials and tube vials, which largely avoids the eccentricity error caused by the shaking and instability of the target point and increases the stability of the measurement. . However, the disadvantage of this device is that the precision base is not retractable, and it is greatly restricted by the terrain and the site environment, which affects the vision of the total station.
