AI Technical Summary
The legs of existing auxiliary supports for directional drilling through geological faults are fixed and non-adjustable, which makes them prone to sinking under mechanical vibration, affecting the stability of the directional drilling.
An auxiliary support system was designed, comprising a rectangular frame, a U-shaped frame, a mounting plate, an angle adjustment device, and an adjustable outrigger device. The height of the ground support rod is adjusted by the adjustable outrigger device, and the frame is kept balanced by the angle adjustment device and the hydraulic telescopic rod, thus ensuring the stability of the directional drill.
With adjustable outriggers and angle adjustment devices, the height and angle of the support rods can be adjusted under mechanical vibration to prevent the support from tilting, ensuring the stable operation of the directional drill. The structure is simple and easy to use.
