A measuring instrument tower ruler support

technical field

The utility model relates to the field of measuring auxiliary tools, in particular to a measuring instrument tower ruler bracket.

Background technique

In electric power construction operations, measuring instruments such as theodolites or levels are often used to measure various types of numerical measurements on the construction work surface. Every time a measurement is carried out, a special person is required to support the tower ruler, which is labor-intensive.

At the same time, when the ruler is manually held up, people are used as supports, and the slight shaking of the person holding the ruler will affect the alignment operation of the crosshairs, and repeated alignment readings increase the measurement time.

If the staff of the ruler cannot place the tower ruler completely vertically on the ground during the measurement, it will cause a large error in the reading or an error in the reading. The wrong value will leave a safety hazard for the follow-up work, and the measurement will be repeated again, resulting in low work efficiency.

However, the tower ruler support in the prior art is cumbersome to fix the tower ruler, and after fixing, it is necessary to use an additional instrument to measure the angle of the tower ruler, and then adjust the tower ruler support according to the measured angle until the tower ruler is completely perpendicular to the horizontal plane, which is very easy to operate. inconvenient.
