AI Technical Summary

Technical Problem

During the installation of high-voltage frequency converters, due to varying levels of operator skill and limitations in the size of the reinforcing beam, the positioning device may move asynchronously, leading to the risk of jamming and equipment falling.

Method used

A positioning device was designed, comprising an extendable suspension rod, a slide, a moving device, and a lifting device. The extendable suspension rod and moving wheels, in conjunction with a reinforced crossbeam, enable the high-voltage frequency converter to move in the vertical, left-right, and front-back directions. Right-angle plates and limit rods are used to prevent asynchronous movement and enhance the adaptability of the equipment.

Benefits of technology

This effectively prevents the positioning device from getting stuck during movement, reduces the risk of the equipment falling, and improves the stability and safety of the installation process.
