AI Technical Summary
When replacing drill rods of different sizes of the existing rock drill trolley, the drill holder cannot effectively support the thinner drill rod, resulting in unstable drilling holes and inconvenient replacement.
A propulsion beam structure of a rock drill trolley is designed, including electric sliders A and B, support mechanism and drilling mechanism. The support mechanism uses the middle and tail support components to adjust the position of the drill rod and rack system to ensure the stable movement of the drill rod between the two arc blocks. The drilling mechanism drives the drill rod to rotate slowly through the motor, gear and installation shaft to avoid losses.
This structure solves the problems of drilling instability and inconvenient replacement by adjusting the position and rotation speed of the drilling rod, and improves drilling efficiency and stability.
