Extension drill rods are crucial components in the operation of tunnel drilling rigs. They transmit the impact energy and torque of the rock drill to the drill bit, enabling the drilling of holes in hard media such as rocks. These rods have male threads on both ends and are available in various specifications, including the T45 diameter 38mm rods.
Details about T45 Extension Drill Rods
Raw Material: High-quality alloy structural steel, such as 23CrNi3Mo, is used to manufacture these rods. Alloying improves the material’s strength, toughness, and wear resistance, allowing it to adapt to more severe working conditions.
Shape and Size: The length of the drill rod typically depends on the drilling depth requirements of the rock drilling rig. Common lengths include 3060mm and 3660mm. One end connects to the shank adapter of the rock drill, while the other end connects to the drill bit through a threaded connection.
How to Use T45 Diameter 38mm Extension Drill Rods
Using T45 diameter 38mm extension drill rods involves several steps, including preparation, drilling, maintenance, and safety precautions.
Preparation
Inspect the Drill Rods: Before use, inspect the drill rods for any signs of damage or wear. Ensure that the threads are in good condition and free from debris.
Select the Appropriate Equipment: Ensure you have the correct drilling equipment that can accommodate T45 threaded connections and 38mm diameter drill rods.
Assemble the Drill Rods: If the drill rods are in sections, assemble them by screwing the threaded ends together. Ensure that the connections are tight and secure.
Drilling
Mount the Drill Rod: Attach the assembled drill rod to the drilling equipment. Ensure that it is securely fastened and aligned properly.
Start Drilling: Begin drilling at the desired location. Monitor the drilling process to ensure that the drill rod is not overheating or experiencing excessive vibrations.
Maintain Control: Keep a firm grip on the drilling equipment and maintain control at all times. Adjust the drilling speed and pressure as needed based on the material being drilled.
Maintenance
Cooling and Lubrication: During long drilling operations, use cooling fluids or lubricants to prevent overheating and reduce friction. This will help prolong the life of the drill rod.
Regular Inspections: Periodically inspect the drill rod for signs of wear or damage. Replace any damaged parts immediately to avoid accidents or equipment failure.
Proper Storage: After use, clean the drill rod thoroughly and store it in a dry place. Protect the threads with thread protectors or caps to prevent damage during storage.
Safety Precautions
Personal Protective Equipment (PPE): Wear appropriate PPE such as safety glasses, gloves, and ear protection while handling and operating the drill rod.
Follow Safety Procedures: Adhere to all safety procedures and guidelines provided by the equipment manufacturer and your organization.
Additional Tips for Using T45 Extension Drill Rods
When installing the drill rod, ensure that it connects firmly to the rock drill and the drill bit.
During rock drilling, adjust the impact frequency and pressure of the rock drill according to the nature of the rock to avoid excessive impact and overload, which can extend the service life of the drill rod.
Regularly check the wear of the drill rod and replace it in time if obvious wear, cracks, or other defects are found on its surface.
Clean the drill rod regularly to remove impurities such as rock debris and oil. When storing, place it in a dry and ventilated place to avoid moisture and rust.
For worn drill rods, consider repair technologies such as surfacing welding to reduce the cost of use.
By following these steps and tips, you can effectively use T45 diameter 38mm extension drill rods in your drilling operations.
