AI Technical Summary

Technical Problem

Existing coal mine tunneling and drilling equipment is inadequate in terms of drill rod replacement and automation, resulting in high labor intensity, long downtime, high energy consumption, and safety hazards.

Method used

The propulsion mechanism, which links the storage and pushing components, enables automatic replenishment and rapid docking of drill pipes. The automatic docking and fixing of drill pipes is completed through the coordinated use of centering clamps, propulsion mechanism and elastic fixing components, reducing manual operation.

Benefits of technology

It achieves continuous drilling without downtime, reduces overall machine power consumption, improves drill pipe docking efficiency, reduces labor intensity and safety hazards, ensures drill pipe coaxiality, and reduces drill pipe scrap rate.
