AI Technical Summary

⚠Technical Problem

The installation of existing type E elastic clips is time-consuming, labor-intensive, and inefficient. It also damages the coating on the surface of the insulating and corrosion-resistant rail, reducing the service life of the rail and posing safety hazards.

⚗Method used

A semi-automatic elastic bar installation device was designed, including a slide rail, a support base, a clamping mechanism, a drive device, and a linear telescopic mechanism. Through a gantry structure and automated drive, the elastic bar is assisted in inserting into the iron base, avoiding direct manual contact, reducing labor intensity, and protecting the coating on the track surface.

🎯Benefits of technology

It improves the efficiency of elastic rail installation, reduces labor intensity, protects the insulating coating on the rail surface, extends the service life of the rail, and eliminates safety hazards.
