A high-precision double-layer aiming guide rail

Abstract

The invention discloses a high-accuracy two-layer collimating guide rail which comprises a guide rail component, an upper cover component and a lower cover component, wherein the guide rail component comprises a sliding base, an upper sliding plate slidingly mounted on the upper surface of the sliding base, an upper pressing block used for limiting linear sliding of the upper sliding plate, a lower sliding plate slidingly mounted on the lower surface of the sliding base, and a lower pressing block used for limiting linear sliding of the lower sliding plate; sliding directions of the upper sliding plate and the lower sliding plate are perpendicular; the upper cover component comprises an upper cover plate used for mounting and fixing a theodolite; a locking mechanism used for locking and fixing the theodolite is arranged on the upper surface of the upper cover plate; the lower cover component comprises a lower cover plate connected with a tripod; the lower sliding plate is fixedly mounted on the upper surface of the lower cover plate, and reversely mounted on the lower surface of the sliding base in a pressing manner via the lower pressing block; the upper sliding plate is forward mounted on the upper surface of the sliding base in a pressing manner via the upper pressing block; and the upper surface of the upper sliding plate is fixedly connected with the lower surface of the upper cover plate. The guide rail is applicable to adjustment of the theodolite.

Description

technical field [0001] The invention relates to an accessory for adjusting the field of view range of a theodolite, in particular to a high-precision double-layer aiming guide rail. Background technique [0002] At present, precise optical aiming is required in optical benchmark testing, field surveying and mapping, true north benchmark calibration, and missile aiming, and high-precision theodolites are generally used for horizontal benchmark conversion. Its use process is as follows: fix the tripod - set up a high-precision theodolite on the tripod - adjust the level of the high-precision theodolite - aim at the A target reflector - aim at the B target reflector - determine the A and B target reflections through the high-precision theodolite Angular position relationship between mirror normals. [0003] However, during the aiming process of the high-precision theodolite, it often occurs that the target reflector is at the edge of the field of view of the high-precision the...

Problems solved by technology

In this way, during use, due to the need to frequently move the position of the tripod or the target mirror, the aiming time of the high-precision theodolite will be greatly prolonged, and the efficiency is low.
