Horizontal adjusting tool and calibration method in mounting of inertial navigation device during ship inclination

Abstract

The invention discloses a horizontal adjusting tool. The tool comprises pillars, a supporting panel, bolts, nuts, a bottom plate, an elbow plate, and an instrument mounting panel. The pillars are placed on the deck of a ship. The pillars, the supporting panel, and the bolts are welded to form a combined supporting base. The bottom plate, the elbow plate, and the instrument mounting panel are welded to form a combined instrument mounting and adjusting base. The combined supporting base and the combined instrument mounting and adjusting base are fixed by the nuts. The nuts are separately screwedon the bolts, and are separately located on the upper surface of the bottom plate and between the supporting panel and the bottom plate. The horizontal adjusting tool can effectively control the calibration precision of the mounting of an inertial navigation device, and meets the precision requirements of the output data of the relevant systems of the ship for the inertial navigation device.

Description

technical field [0001] The invention belongs to the technical field of installation and calibration of ship inertial navigation equipment, and in particular relates to a horizontal adjustment tool and a calibration method in the installation of inertial navigation equipment when the ship is tilted. Background technique [0002] Ship inertial navigation equipment is an important device that provides ship attitude information such as heading angle, pitch and roll, etc., and its installation and calibration accuracy directly affects the accuracy of output information. The high-precision inertial navigation equipment installation and calibration process is to give full play to the An important guarantee for combat performance. [0003] Ships are usually divided into dock construction, horizontal berth construction, inclined berth construction, etc. Dock construction and horizontal berth construction control the attitude of the hull from the segmental / total segment loading stage,...

AI Technical Summary

Problems solved by technology

[0003] Ships are usually divided into dock construction, horizontal berth construction, inclined berth construction, etc. Dock construction and horizontal berth construction control the attitude of the hull from the segmental / total segment loading stage, precision control is easy to achieve, and conventional calibration processes can ensure Accuracy has been calibrated; for ships built with inclined berths, some equipment cannot be installed on the berth, the slope of the berth is large, and the accuracy control requirements of the test instruments are high. As a result, the berth stage does not meet the calibration status requirements or the test instruments cannot maintain accuracy. For work, etc., the ship needs to be re-docked after launching to install the equipment to meet the calibration status requirements, but the control of the ship's horizontal attitude is often difficult to meet the technical requirements during docking, resulting in the failure of the conventional calibration process to carry out installation and calibration work

Due to the influence of the tide, it is difficult to adjust the posture of the ship's pier to meet the level requirement, and it also takes a long time to barge out the water in the dock, which is time-consuming and uneconomical
