Description

Technical Field

[0001] The invention belongs to the technical field of optical surveying and mapping, and in particular relates to a slide rail type theodolite maintenance support device and a use method thereof. Background Art

[0002] As an important precision optical surveying instrument, theodolite is widely used in military and civilian fields such as bridges, tunnels and equipment aiming. It is usually composed of a base, a leveling system, an optical alignment system, a reading system, etc. When the leveling screw on the theodolite fails, the theodolite needs to be placed on its side to remove the locking nut on the theodolite base for fault diagnosis and repair.

[0003] At present, the theodolite is usually placed sideways on a flat table for disassembly and maintenance of the base. This lateral support method is simple and convenient for small and medium-sized theodolites with low and medium precision, but it is not applicable to medium and large theodolites with high precision. The main reasons are as follows:

[0004] First, the external structure of the theodolite is irregular in shape, making it difficult to find a suitable and stable support point;

[0005] Second, the theodolite is relatively heavy, and the lateral support method can easily crush the micrometer components, horizontal locking components and other parts on the theodolite, causing irreversible physical damage.

[0006] For the maintenance of high-precision medium and large theodolite bases, the pad support method is generally adopted. That is, a wooden block or iron block is placed at the appropriate position of the side head of the theodolite for support. This pad support method effectively protects the precision mechanical parts of the theodolite such as the micrometer device and locking device, but at the same time, the risk of the theodolite slipping or rolling and being damaged is also relatively large.

[0007] Therefore, the present invention considers it necessary to design a base maintenance support device for medium and large theodolites. Summary of the invention
