Laser calibration device for loading compass

Abstract

The invention discloses a laser calibration device for loading a compass. The laser calibration device comprises a support frame, wherein a rotatable compass seat is arranged on the support frame, a transverse calibration line and a longitudinal calibration line which are vertically crossed with each other are fixed at the top of the compass seat, and a crossing point of the transverse calibration line and the longitudinal calibration line is aligned with an axle center of the compass seat; a mounting site for placing the compass is formed in the top of the compass seat and is located below the transverse calibration line and the longitudinal calibration line; and two transverse laser emitters and two longitudinal laser emitters are mounted at the side part of the compass seat, laser beams emitted by the two longitudinal laser emitters are respectively aligned with extension lines of two ends of the transverse calibration line, and laser beams emitted by the two longitudinal laser emitters are respectively aligned with extension lines of two ends of the longitudinal calibration line. The laser calibration device can be adjusted to a calibration direction without visual inspection, and meanwhile, the direction can be indicated by virtue of the laser beams, so that the deviation caused due to the visual inspection is reduced, and furthermore, the survey accuracy is greatly improved.

Description

technical field [0001] The invention relates to compass bearing and operating equipment, in particular to a laser marking device for loading a compass. Background technique [0002] The compass is an instrument used for geographic survey. During its application, it needs to be placed on a stable support frame to observe data accurately. For this, support equipment similar to camera tripods appeared on the market to serve as auxiliary support. effect, but these existing supporting equipment only have the effect of placing and supporting, and in its actual application process, there are still following defects: [0003] 1. After the compass is placed on the support frame, it needs to rely on visual inspection and reference objects to adjust it to the calibration position, such as the longitude and latitude. Only after the reference to the azimuth calibration can accurate survey be realized, but this visual inspection method has visual deviations Large size, multi-person coord...

AI Technical Summary

Problems solved by technology

[0003] 1. After the compass is placed on the support frame, it needs to rely on visual inspection and reference objects to adjust it to the calibration position, such as the longitude and latitude. Only after the reference to the azimuth calibration can accurate survey be realized, but this visual inspection method has visual deviations Large size, multi-person coordination operation, low efficiency, poor survey accuracy and other defects;

[0004] 2. In order to fix the compass at the preset position, the existing support frame is usually equipped with structures such as compass fixtures, positioning holes, and installation holes, but these structures can only be installed with a single type of compass. For a wide variety of compasses on the market It is difficult to achieve clamping, resulting in insufficient compatibility;

[0005] 3. When the compass is placed on the support frame, it is necessary to adjust the compass to a horizontal state. The existing method is to use the level as a reference and adjust the stretching length of the tripod at the same time. However, this method is not only inefficient, but also difficult to level accurately ;

[0006] 4. When it is necessary to calibrate the compass and compass to rotate the compass, it is usually driven by the handle or hand push. The stroke of this adjustment method depends entirely on the user's thrust. The adjustment method is single, and it is difficult to adjust the compass to the specified direction;

[0007] 5. When the compass calibrates the horizontal and vertical lines and the compass does not move, when it is necessary to add marking lines in any angle direction, two people need to hold one end of the line and stand opposite the center of the compass, and one person in the middle looks at the line and guides the compass to take it. Two people on the line rotate the directional marking around the center. This adjustment method is complicated and requires the coordination of multiple people, and the accuracy is low.

[0008] Due to the above deficiencies, the existing compass auxiliary equipment cannot fully play its role, which brings inconvenience to the user's use process
