Abstract

The invention relates to the technical field of drill rods, in particular to a hard rock drill rod. The hard rock drill rod comprises a drill rod body and a connecting mechanism arranged on the drillrod body, the connecting mechanism comprises a first connecting assembly and a second connecting assembly, the first connecting assembly and the second connecting assembly are arranged at the two endsof the drill rod body respectively, the first connecting assembly comprises a connecting block and a locking block arranged at the upper end of the connecting block, a locking hole is formed in the locking block, the second connecting assembly comprises a connecting groove, a locking pin hole formed in the top of the connecting groove and a buffering wedge block arranged in the connecting groove,and a buffering assembly is arranged in the buffering wedge block. The hard rock drill rod is simple in structure and convenient to connect, the drill rod body can be efficiently connected, the torsion resistance of the hard rock drill rod in the drilling process can be effectively improved, and the service life of the drill rod body is prolonged.

Description

technical field [0001] The invention relates to the technical field of drill rods, in particular to hard rock drill rods. Background technique [0002] During rock drilling, the drill bit rotates around the vertical axis and moves axially at the same time. The hard rock is cut under the torque and axial force of the drill bit, and is destroyed and loosened under the extrusion and centrifugal force of the working blades, forming a soil flow that is pressed to the pit wall and is lifted out of the borehole along the page. . Different types of drill bits are used for rock drilling with different hardness. For the soft rock with less hardness, the rotary drill bit is mostly used, and for the hard rock with higher hardness, the percussion drill bit is mostly used. Due to the high difficulty of drilling complete hard rock, when the current drill pipe is drilling hard rock, due to the huge impact force and axial force generated during the drilling process, it is very easy to mak...
