What is a threaded drill rod?
Threaded drill rods (also called hydraulic drill rods/hydraulic drill rods, heavy drill rods/heavy drill rods, trolley drill rods/trolley drill rods, large diameter threaded drill rods are also called drill pipes and guide drill pipes. The English name of threaded drill rods is drill rods, and the English name of drill pipes is drill tubes.) Threaded drill rods are generally used with hydraulic rock drilling trolleys and hydraulic rock drilling rigs to drill blasting holes, anchor holes, or as guide drill rods. There are also a few supporting pneumatic rock drilling equipment, such as 90 drilling rigs, shaft drilling rigs, etc.
During the operation of hydraulic rock drilling trolleys and drilling rigs, the drill tool group consisting of a drill head, a drill rod, a connecting sleeve, and a drill tail transmits the impact power of the hydraulic rock drill, and the drill head directly drills the rock. The drill rod is an important component in the drill tool group with complex force and demanding requirements, and the quality and performance requirements of the drill rod are very strict. According to the supporting equipment and application fields, threaded drill rods can be divided into drill rods for underground mining excavation and rock drilling, drill rods for underground medium and deep space mining and rock drilling, drill rods for underground anchoring and rock drilling, drill rods for tunnel engineering excavation and rock drilling and anchoring, drill rods for open-pit mining, quarrying, and open-pit engineering rock drilling, etc.
