6 FAQs about [Working principle diagram of rock drill rod changer]

How do you rotate a drill rod?

Hydraulic or pneumatic rotation motors are most frequently used to rotate the rod, although small pneumatic rock drills often employ a rifle rotation system, in which the drilling rod is rotated by a piston via a rifle bar without the need for a pneumatic motor. 2.4. Drilling Rod

How does a rock drill work?

All drilling methods require a feeding system that pushes the drilling tool against the rock, maintains the advance of the bit as drilling progresses, and withdraws the tools once drilling is complete. A heavy weight or a pneumatic (pusher-) leg is used with hand-held rock drills.

What are the components of a drilling system?

The essential components of a drilling system are the rock drill, feed equipment, drilling rods, bit, supports against the drilling reaction, power source, and cuttings disposal equipment. Different drilling rigs are constructed with various combinations of these elements and other accessories for particular drilling purposes. 2.1. Working Fluid

How does a drilling tool work?

When drilling in rock, the sharp end of the drilling tool, or bit, is driven into the rock by means of a dynamic (percussion, in which the bit rotates slightly in response to each stroke) or static force (rotation). The material excavated by the bit is stripped out of the hole by shearing as the bit advances.

How do percussion drills work?

With percussion drilling, the bit is driven into the rock by either a top hammer, in which case the drill rods transmit the impact of a blow at the surface, or a “down the hole drill” in which the hammer itself is in the hole and impacts the bit directly. 1.2. Drill Adaptability

Why are rock drilling tools difficult to operate?

Fragile rock drilling tools: due to the manual operation’s error of manual operation, the push speed is difficult to control accurately, which causes the thread of the rock drilling tools to be damaged due to the rigid transmission force. Inefficiency: complex operation steps and uncertainty of manual control affect the operation efficiency.
