AI Technical Summary

Technical Problem

The installation stability of the high-pressure hose assembly and quick coupling of the existing mining anchor cable tensioning machine is poor. Vibration can easily cause the preload of the threaded pair to decrease, affecting the stability and safety of the equipment.

Method used

The threaded connection combined with the spring clamp structure improves the stability of the threaded connection by adapting the clamp and the clamp cavity, and uses the elastic preload of the spring to maintain the stability of the clamp within the clamp cavity.

Benefits of technology

It improves the installation stability between the high-pressure hose assembly and the quick coupling, reduces thread loosening caused by vibration, and enhances the stability and safety of the equipment.
