AI Technical Summary
Existing borehole enlargement devices used for underground coal mine geological exploration suffer from low efficiency and poor accuracy in centering and debugging, and lack effective clamping protection during drill pipe disassembly, resulting in poor quality and insufficient safety in borehole enlargement operations.
A laser emitter is used to assist in centering, a ranging component is used to assist in centering and debugging, and a clamping mechanism is set on the outside of the sliding connecting sleeve to realize automatic clamping and adaptive adjustment of the drill rod.
It improves the efficiency and safety of borehole enlargement operations, reduces manual measurement and debugging time, lowers the labor intensity of operators, and avoids accidents such as drill rod falling and equipment damage.
