AI Technical Summary

Technical Problem

Existing gearbox installation and alignment devices are complex in structure and cumbersome in procedure, especially when symmetrically arranged on both sides of the load equipment, resulting in low installation efficiency and increased production costs and manufacturing difficulty.

Method used

A dual calibration method using a laser tracker and a dial indicator is employed. The gearbox is quickly coarsely aligned horizontally via laser projection, and the alignment device is used to adjust the gearbox horizontally and vertically at the bottom and sides respectively. Fine alignment is achieved by combining the real-time detection of the dial indicator.

Benefits of technology

It simplifies the gearbox installation process, significantly improves installation efficiency, reduces construction difficulty and cost, ensures the stability and alignment accuracy of equipment operation, and is suitable for various symmetrical layout conditions.
