Convenient quick-dismantling foldable portable drill rod

Technical Field

The invention belongs to the technical field of drill rods, and particularly relates to a portable drill rod convenient to disassemble and fold quickly.

Background

The drill rod is a steel pipe with threads at the tail part and is used for connecting surface equipment of a drilling machine and drilling and grinding equipment or a bottom hole device at the bottom end of a drilled well. The purpose of the drill pipe is to carry drilling mud to the drill bit and, together with the drill bit, raise, lower or rotate the bottom hole assembly. The drill pipe must be able to withstand large internal and external pressures, twists, bends and vibrations. In the process of oil and gas exploitation and extraction, the drill pipe can be used for multiple times. The drill rods are divided into a kelly, a drill rod and a weighted drill rod. At present, the drill rods of the rotary drilling rig at home and abroad are all multilayer telescopic drill rods, and generally comprise 4 layers, 5 layers or 6 layers. The drill rod in the form has the great advantage that the drill rod can freely stretch and retract according to the hole depth to adapt to different depths and hole diameters, but the problem that the self weight of the drill rod of the rotary drilling rig is large is also brought, the existing drill rod is difficult to fold and is mostly hinged, and multi-angle folding is achieved.
