Description
Technical Field
The application relates to the technical field of engineering measurement, in particular to an automatic balancing device for a leveling prism.
Background
In the current prior art, it is often necessary to use a total station and a prism to perform work such as orientation, distance measurement or measurement on various large buildings or precision projects (for example, measuring the straightness of a crane rail using the total station).
In practical applications, when a total station and a prism are used for performing operations such as orientation, distance measurement, or measurement, the levelness of the prism used often needs to be adjusted to ensure the accuracy of the measurement result of the total station. However, in many cases, due to the limited working space, it is often necessary for a worker to hold the prism by hand, by observing the condition of the air bubbles, and then rely on the worker's working experience to level the prism. This approach is inefficient and the measurement results are greatly affected by human factors, resulting in large errors in the measurement results.
Therefore, it can be seen that how to solve the above-mentioned problem of leveling the prism and effectively improve the work efficiency and the measurement accuracy is a problem that needs to be solved in the art.

a cylinder 32 is arranged at the top of the hemisphere;
the balance bar 15 is fixed on the cylinder 32, and two ends of the balance bar 15 respectively extend out of two sides of the cylinder 32; the extending direction of the balance bar 15 is the same as that of the friction plate 22;
