Description

A measuring instrument installation tool

technical field

The utility model belongs to the field of measuring instrument manufacturing, in particular to an installation tool of a measuring instrument.

Background technique

Level, theodolite and total station are the most commonly used measuring instruments in civil engineering construction. A level is an instrument that establishes a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points according to the principle of leveling. The main components are telescope, tube level (or compensator), vertical shaft, base, foot screw. Theodolite is a measuring instrument designed according to the principle of angle measurement to measure horizontal and vertical angles. It is an angle measuring instrument equipped with a telescope, a horizontal dial and an indicator for reading, a vertical dial and an indicator for reading. Total station is a high-tech measuring instrument integrating light, machine and electricity. It is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, horizontal distance) and height difference measurement functions Once the instrument is installed, all the measurement work on the station can be completed, so it is called a total station. The above three instruments must be fixed with a tripod when in use, and all need to be leveled. In the process of actual use, due to the complex geographical location of erecting the instrument in field operations, and the limited length of the leveling bolt of the instrument, which restricts the range of angle adjustment, it is sometimes difficult to complete the leveling operation. In response to this problem, we have improved the tripod used to mount the instrument.
