What are the characteristics of small aperture rock drills
Small-diameter rock drilling tools mainly include a series of equipment and accessories specially designed for drilling small-diameter holes in rock.These tools are usually high-precision, high-efficiency and capable of adapting to different rock types.The following are the main components of small-diameter rock drilling tools:
button bit:
Diamond drill bit: It is commonly used for hard rock drilling and can effectively penetrate various rocks due to its high hardness and wear resistance.There are various types of diamond drill bits, including surface-mounted diamond drill bits and impregnated diamond drill bits. The appropriate type should be selected based on the rock hardness and drilling requirements.
Hard alloy drill bit: suitable for drilling medium-hard to hard rock, although its hardness is slightly inferior to diamond, it has advantages in terms of cost and applicability.
Drill rod:
Drill pipe is a key component that connects the drill bit and the drill rig, responsible for transmitting torque and axial pressure to the drill bit.The drill rods commonly used in small-diameter rock drilling include hexagonal hollow drill rods, which have sufficient strength and rigidity to ensure the stability and efficiency of the drilling process.
Drilling rig:
Small-diameter rock drilling rigs are the core equipment for drilling operations, and can be divided into pneumatic drilling rigs, hydraulic drilling rigs, and electric drilling rigs according to different power sources.These rigs are usually lightweight and easy to operate, and are equipped with precise control systems to achieve accurate drilling positioning and depth control.
Auxiliary equipment:
Including water pumps, air compressors, mud pumps, etc., used to provide cooling, flushing, and lubricating media required during drilling.These devices are crucial for maintaining the good working condition and extending the service life of the drill bit.
Control system:
Modern small-diameter rock drilling tools are usually equipped with advanced control systems that monitor various parameters (such as torque, pressure, speed, etc.) during drilling, and adjust drilling strategies based on real-time data to improve drilling efficiency and safety.
Safety device:
Including overload protection devices, anti-sticking devices, etc., which are used to stop the equipment and protect personnel safety in case of abnormal conditions during drilling.
Accessories and consumables:
Such as replacement parts for worn drill bits, drill rod connectors, seals, etc. The timely replacement of these accessories and consumables is important for maintaining the good performance and extending the service life of drilling tools.
In summary, small-diameter rock drilling tools are a complex system, including drill bits, drill pipes, drilling rigs, auxiliary equipment, control systems, safety devices, and accessories and consumables.These tools work together to achieve efficient, accurate and safe rock drilling operations.
