Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building equipment, especially an engineering surveying frame for complex terrain. BACKGROUND

[0002] Engineering surveying devices are indispensable tools in the fields of construction, road, bridge and other engineering, which integrate multiple functions such as laser ranging, angle measurement, and horizontal calibration. These devices usually use high-precision sensors and advanced algorithms to ensure the accuracy and reliability of the measurement results. The existing engineering surveying devices have the problem of single function in the process of use, mainly reflected in their inability to adjust height and angle. This limitation directly affects the accuracy and flexibility of measurement. In actual engineering surveying, the environment and terrain are often different, and the height and angle requirements of the measurement points are also different. If the surveying device can only be fixed at a certain height and angle, it cannot adapt to different measurement requirements, resulting in a decrease in the reliability of the measurement results. For example, on a construction site, surveyors may need to perform horizontal and vertical measurements at different heights, and fixed devices cannot meet this demand. In addition, some measurement tasks may require fine adjustment of the device to ensure the accuracy and precision of the measurement line, and the single-function design makes this process cumbersome and time-consuming. Further, devices lacking height and angle adjustment are prone to measurement data deviation when used in complex terrain, increasing the difficulty of subsequent data processing and analysis.
