Surveying Tripod Scale Alignment with Rotational Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surveying stands are cumbersome and difficult to operate, leading to reduced precision in aligning surveying scales vertically and ensuring they face level gauges accurately, requiring repetitive adjustments and complicating the surveying process.
Innovation Solution
A surveying stand with an annular first pedestal and support legs, featuring a scale fixture that can rotate horizontally and a rotation adjustment device, including a second pedestal leveling device with perpendicular screws and springs, allows for precise vertical alignment and angular adjustment of the scale fixture to face the level gauge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional plate-shaped pedestal is used, then the structure is simple, but the surveying scale cannot be fastened and alignment precision is poor
Solution Approach 1:
The pedestal is divided into an annular first pedestal and a second pedestal, with the scale fixture separately mounted on the first pedestal and capable of independent rotation. This segmentation allows the alignment function to be separated from the support function, enabling precise angular adjustment without complicating the overall structure.
Solution Approach 2:
The scale fixture is designed to be rotatable relative to the first pedestal, transforming the static pedestal into a dynamic system. This dynamic capability allows the surveying scale to be precisely oriented toward the level gauge while maintaining structural simplicity through the annular design.
2Productivity
If manual holding and observation of air bubble is used, then no additional devices are needed, but the adjustment process is time-consuming and energy-consuming
Solution Approach 1:
The surveying scale is pre-fastened to the annular first pedestal in a fixed position, eliminating the need for continuous manual holding. The rotation adjustment device allows preliminary positioning followed by secure fastening, significantly reducing adjustment time and energy expenditure while maintaining alignment precision.
3Stability of the object's composition
If the surveying scale is fastened to the pedestal, then vertical stability is improved, but the ability to precisely face the level gauge is compromised
Solution Approach 1:
The scale fixture is designed with rotational capability relative to the first pedestal, allowing the surveying scale to be dynamically adjusted to face the level gauge precisely while maintaining vertical stability through the annular pedestal structure and support legs.
Solution Approach 2:
The rotation adjustment device acts as an intermediary mechanism between the fastened surveying scale and the desired orientation. It enables precise angular adjustment and positioning without compromising the vertical stability provided by the pedestal structure.
4Measurement precision
If repetitive adjustment processes are used to achieve precise alignment, then alignment precision can be improved, but the operation process becomes complicated
Solution Approach 1:
The surveying scale is pre-positioned and fastened to the annular first pedestal at an initial orientation. The rotation adjustment device then enables a single, direct angular adjustment to achieve precise alignment with the level gauge, eliminating the need for repetitive adjustment cycles and simplifying the operation process.
