Large-scale equipment automatically centering method

Abstract

The present invention discloses a large-scale equipment automatically centering method. The method comprises a step of placing centering equipment and target equipment into place; a step of inputting deviation measurement data of a measuring system into a control system; a step that the control system judges if rolling, swaying, pitching, lateral moving and lifting adjustments are needed, calculates an adjustment amount after the adjustments are judged to be needed, drives adjusting devices to complete corresponding adjustment actions, and sends a next-time measuring command to the measuring system according to an adjustment in-place signal until criteria are met; and a step of completing butt joint of the centering equipment and the target equipment after centering. The large-scale equipment automatically centering method is advantageous in that a straight line centering method is adopted, thereby solving the problem of large measuring errors of end face centering adopted by large-scale equipment with small end faces. The method is simple in principle, few in assorted equipment, easy to realize, automatic in execution of all links such as deviation measurement, recognition, resolving, execution, control and feedback, free of manual intervention in the whole process, and high in centering efficiency.

Description

Technical field [0001] The invention relates to a control method, in particular to a method for automatically centering large equipment. Background technique [0002] In aerospace and other fields, it is often necessary to align two or more large-scale equipment with a unified attitude so that they can be docked to form a whole for work. For example, two large-scale equipment with long guide rails are quickly connected to make the guide rails on the two equipment collinear, thereby forming a continuous running track for other equipment to walk. However, the initial placement and operation of the two equipment is relatively large. Deviations need to be adjusted for alignment (called "straight alignment"). Generally speaking, only one of the two large-scale equipment needs to have the ability of centering adjustment. For the convenience of description, we call the device with the centering ability the centering device and the other device as the target device. [0003] In the tradi...

AI Technical Summary

Problems solved by technology

The above three methods are all applied to the general assembly of the process, and there are relatively many preparations for the centering equipment. The technical indicators of automatic centering focus on accuracy requirements, and the time requirements are relatively loose, and the automatic centering system for ship berth closing is used in ship assembly. Manual input of initial attitude information is required, and the hydraulic automatic centering system used in large flange installations is suitable for vertical centering of centering equipment in a free state of space, and is not suitable for quick centering of two super-long products

[0007] To sum up, there is no mature technology to realize the centering control of large-scale equipment.
