Description

Technical Field

[0001] The utility model relates to the technical field of surveying instruments, in particular to a surveying instrument adjustment device for engineering surveying and mapping. Background Art

[0002] Engineering surveying and mapping requires extremely high precision. As one of the core tools, the accuracy of the surveying instrument directly impacts the data accuracy of the entire project. On complex construction sites, the stability and convenience of the surveying instrument are of paramount concern to engineers. However, the adjustment devices of most surveying instruments currently available in the market still have design deficiencies, particularly the non-adjustable angle of the support legs and the resulting poor horizontal stability. These issues significantly limit the efficiency and quality of surveying and mapping work.

[0003] The non-adjustable leg angle means that the installation and adjustment of the surveyor becomes extremely difficult when faced with uneven ground. When working in the field, the terrain varies greatly, from mountains to deserts, from cities to rural areas, and the surveyor needs to adapt to a variety of different ground conditions. If the leg angle cannot be flexibly adjusted according to the actual situation, it will be difficult to find a suitable support point to place the surveyor on tilted or undulating ground, which not only increases the difficulty of surveying and mapping, but also greatly reduces the reliability of the measurement data. In addition, in some cases, in order to find a relatively flat location to place the surveyor, engineers have to spend extra time and energy to level the ground, which undoubtedly increases the time cost of the surveying and mapping task.

[0004] Poor horizontal stability further complicates surveying. Surveying instruments must remain absolutely level during use to ensure accurate data. However, due to the fixed-angle design of their legs, the instruments are susceptible to deviation from even slight vibrations or wind, affecting measurement results. Especially during long-distance measurements or high-rise construction, even the slightest deviation can have serious consequences. For example, in high-rise construction, deviations in basic data can pose safety risks to the building's overall structure; in bridge construction, they can cause asymmetry in the bridge deck, compromising vehicle safety.

[0005] Therefore, how to provide a surveying instrument adjustment device for engineering surveying is a problem that those skilled in the art urgently need to solve. Utility Model Content

If the leg angle cannot be flexibly adjusted according to actual conditions, it will be difficult to find a suitable support point to place the surveyor on tilted or undulating ground, which not only increases the difficulty of surveying and mapping, but also greatly reduces the reliability of measurement data. In addition, in some cases, in order to find a relatively flat location to place the surveyor, engineers have to spend extra time and energy on leveling the ground, which undoubtedly increases the time cost of surveying and mapping tasks.
