AI Technical Summary
Existing mining tunneling equipment cannot flexibly adjust the angle of the tunneling head when encountering bends, deflections, or fault zones, leading to deviation or mechanical damage.
The tunneling head employs both coarse and fine angle adjustment mechanisms. The angle of the tunneling head is adjusted through components such as slide rails, pulleys, and electric hydraulic cylinders. By combining the sliding connection between the pulleys and slide rails with the extension and retraction of the electric hydraulic cylinders, large-angle rapid adjustment and small-angle precise control are achieved.
It enables efficient and precise adjustment of the tunneling head posture in complex geological environments, improving operational efficiency and reducing the risk of mechanical damage.
