Description

Technical Field

[0001] The utility model relates to the technical field of RTK measuring instruments, in particular to a supporting frame for RTK measuring instruments with a telescopic function. Background Art

[0002] RTK surveying instruments are a technology that uses GPS carrier phase observations to perform real-time dynamic relative positioning. As a surveying device: RTK surveying instruments can receive satellite signals to achieve high-precision positioning. The positioning accuracy of RTK surveying instruments can reach centimeter level. It is suitable for field digital mapping, photogrammetry and remote sensing, and control point measurement in engineering surveying. Using RTK for control measurement can know the positioning accuracy in real time. If the point accuracy requirements are met, the observation can be stopped. Measuring a control point can be completed within a few minutes or even seconds, and the quality of the observation can be known. Using RTK surveying instruments for control measurements with low requirements such as roads, railways, and water conservancy projects can not only greatly reduce manpower intensity and save costs, but also greatly improve work efficiency.

[0003] When an RTK measuring instrument is used outdoors, it needs to be supported by a tripod or other supporting frame. The existing tripod can only be simply expanded outward for stabilization when in use, and can be retracted when not in use to reduce the bottom occupied area.

When carried, the RTK measuring instrument is directly exposed to the outside and has a high risk of being damaged by accidental collision. In addition, the method of using a storage box alone to store the instrument is not ideal in terms of integrity and convenience. In view of this, a supporting frame for an RTK measuring instrument with a telescopic function is proposed. Utility Model Content
