Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of verticality detection, in particular to a verticality detection device for a geological exploration drill rod. BACKGROUND

[0002] A geological drill rod is a key hole bottom power component in geological exploration engineering, and its main function is to transmit drilling equipment and power to the hole bottom, drive the drill bit to break rocks, and form a continuous core. The drill rod is usually made of high-strength alloy steel and is subjected to precise heat treatment process to ensure excellent tensile, torsional, compressive and fatigue resistance in complex strata (such as hard rock strata, abrasive strata). The standard drill rod structure includes a rod body, a threaded joint and other parts, and its outer diameter and wall thickness need to be strictly designed according to the drilling depth, hole diameter and drilling process to ensure the overall stability and power transmission efficiency of the drill string. During drilling, the drill rod needs to withstand huge torque, tension and vibration, and the internal passage is used to transport drilling fluid to cool the drill bit, carry cuttings and protect the wall.

[0003] In geological exploration operations, the verticality of the drill rod string is a key indicator to ensure drilling quality, core recovery rate and equipment safety. When detecting the verticality, if the drill rod loosening phenomenon is found or accompanied, the drill rod loosening will directly affect the accuracy of the verticality detection. Inaccurate verticality detection will not only reduce the representativeness and accuracy of the rock core sampling, but also mislead the subsequent geological interpretation, and more likely to cause hole wall collapse, sticking and other major accidents in complex strata.

An automatic positioning mechanism 4 is used to automatically clamp the drill rod body 5. The automatic positioning mechanism 4 is fixed to the movable end of the drive mechanism 3. By setting the automatic positioning mechanism 4, the automatic centering and reliable fixing of drill rods of different diameters are achieved by adopting the adaptive clamping principle.
