Mounting Bracket For New Movable Azimuth Sub-compass.

For a long time, the gyro compass, as a navigation instrument that can accurately find the geographic north direction, has been widely used on various ships and has become the main instrument for marine navigation. As a repeating device for gyro compass, the sub-compass can be installed in multiple positions of the ship to provide real-time heading information. In addition to repeating the heading, the azimuth sub-compass can also be used in conjunction with the sub-compass bracket and observation equipment to determine the broad angle or gyro bearing of the target.

    At present, most of the azimuth subcompass brackets used in shipping are floor-standing vertical installation or wall-mounted installation, and the installation position is located on the bow and stern lines or both sides of the ship. After the installation is completed, the bracket is fastened and cannot be moved. If the line of sight in the observation direction is blocked, it will bring inconvenience to the observation work.

In order to overcome this problem, a new mounting bracket for mounting the bearing sub-compass has appeared. This mobile azimuth sub-compass bracket adopts optical axis and linear guide rail as linear guide and support, which ensures the parallelism of the azimuth sub-compass baseline and the ship's bow and stern line during the moving process, which makes the moving process easy and stable, and can be easily passed through The locking device locks the moving parts.

    The mounting bracket of the movable azimuth sub-compass has a relatively compact overall structure, convenient installation, flexible movement and good straightness. It can be moved and locked within the moving range very conveniently. Compared with the original azimuth sub-compass bracket The mounting bracket of the present invention makes it more convenient to use the azimuth sub-compass to measure the azimuth of the object mark or the gyro azimuth, and reduces the influence of the surrounding environmental factors on the measurement work.
