Problems solved by technology

In the test, if the instrument is centered first, and then the instrument is leveled, it will cause errors in the instrument centering
If leveling is performed first, and then centering, it will cause the instrument to be leveled and fail
[0003] In the theodolite experiment, the contradiction between centering and leveling has been difficult to coordinate
Among the existing theodolite centering and leveling methods, there is a circular centering and leveling method, which takes a long time
Another method of centering and leveling the tripod. This method needs to move the tripod after installing the theodolite, which may cause the tripod to fall over, so it is difficult to use in uneven areas such as mountains

Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0017] The centering and leveling method of the theodolite of the present invention, before the theodolite is centered and leveled, the rough centering and leveling of the tripod are carried out earlier, specifically comprising the following steps:

[0018] (1) Adjust the tripod of the theodolite to be equal in length and suitable for the height of the operator, so that the plane of the tripod tends to be horizontal, roughly centered, and step on the feet firmly;

[0019] (2) Place a circular level on the tripod plane, extend the length of the legs of the tripod and level the circular level on the tripod;

[0020] (3) Remove the circular level and fix the theodolite on the tripod so that the base surface of the instrument is parallel to the top surface of the tripod;

[0021] (4) Parallel the level tube...

Abstract

The invention relates to a theodolite centralizing and leveling method. The theodolite centralizing and leveling method comprises the following steps that 1, a tripod of a theodolite is adjusted to be equal in height and suitable for the height of an operator, a tripod plane is made tending to be horizontal, rough centralizing is performed, and tripod feet are treaded stably; 2, a circular level is arranged on a tripod plane, and the circular level on the tripod is leveled by telescoping the tripod feet; 3, the circular level is taken down, the theodolite is fixed on the tripod, and an instrument base plane is made parallel to the upper top face of the tripod; 4, a leveling tube is parallel to two leveling screws and is leveled; 5, an alidade is flatly turned at 90 degrees, and the leveling tube is leveled by using a third screw; 6, optical centralizing is performed, a connecting screw is opened to translate a base so as to achieve accurate centralizing of the base, and the connecting screw is screwed tightly. The theodolite centralizing and leveling method is convenient to operate and high in efficiency, the situation that an error is produced during theodolite centralizing and leveling is avoided, and the precision of the theodolite can be well ensured.

Description

technical field [0001] The invention relates to a method for centering and adjusting a theodolite, which belongs to the technical field of engineering surveying and testing. Background technique [0002] Practice shows that the centering and leveling of the theodolite will interfere with each other in the test. In the test, if the instrument is centered first, and then the instrument is leveled, it will cause errors in the instrument centering. If leveling is performed first, and then centering, it will cause the instrument to be leveled and fail. [0003] In the theodolite experiment, the contradiction between centering and leveling has always been difficult to coordinate. Among the existing theodolite centering and leveling methods, there is a circular centering and leveling method, which takes a long time. Another tripod centering and leveling method, this method needs to move the tripod after installing the theodolite, which may cause the tripod to fall over, so it is...
