AI Technical Summary

Technical Problem

Existing steering devices are unable to provide sufficient operating space in narrow, complex, and undulating underground roadways, have poor adaptability, and weak multi-directional adjustment capabilities, especially at the working face end or roadway intersections where it is difficult to achieve steering angles of 90 degrees or greater.

Method used

The device design includes telescopic rails, transport rails, short-connection rails, and a turntable transport vehicle. The innovative turntable transport vehicle enables small-radius or even near-in-situ turning, with a compact structure that reduces the space occupied in the tunnel.

Benefits of technology

It can efficiently complete turns of 90 degrees or greater in narrow areas, significantly reducing the requirements for roadway width and turning radius, and is suitable for critical narrow areas such as working face ends and roadway intersections.
