This Drill Steel Support is a core positioning and stabilizing accessory designed for drilling equipment, including drill jumbos and rotary drilling rigs. Serving as the "guidance hub" at the front of the drill boom, it is primarily responsible for stabilizing the drill steel posture during high-frequency percussion and rotation, withstanding massive reaction forces and radial vibrations. Through optimized structural mechanics, this support effectively disperses drilling stress, preventing the drill steel from deflecting, oscillating, or fracturing during deep rock penetration. It ensures the verticality and accuracy of blast holes, making it ideal for applications such as building pile foundation construction, mine rock bolting, and tunnel excavation.
Carbon Steel Stamped Body & Alloy Steel Reinforcement:
The main structure is formed from high-quality carbon steel via stamping and bending processes, offering excellent structural rigidity and cost-effectiveness. Critical load-bearing areas subjected to the highest impact are specifically reinforced with alloy steel forged ribs. The forging process imparts exceptional tensile strength and toughness to the ribs, effectively absorbing severe vibration during drilling to prevent bracket tearing or deformation, ensuring lasting and reliable holding power.
Wear-Resistant Cast Iron/Copper Alloy Bushings:
The guide surfaces in direct contact with the drill steel are fitted with wear-resistant bushings made of cast iron/copper alloy. Compared to standard steel bushings, copper alloy offers superior self-lubricating properties and wear resistance. This significantly reduces wear on the expensive drill steel, lowers replacement frequency, and allows for short-term operation even under poor lubrication conditions, protecting the drill string from damage.
Shot Blasting & Dark Gray Anti-Corrosion Topcoat:
The surface undergoes shot blasting to彻底 remove scale, welding slag, and rust, increasing roughness for better coating adhesion. It is then finished with a dark gray anti-corrosion topcoat. This coating provides a professional finish with excellent weather resistance and stone-chip resistance to withstand acidic mine water, mud, and rock debris, preventing substrate corrosion.
Precision Polished Mating Surfaces:
All mounting interfaces that connect to the equipment are precision polished. This ensures perfect conformity between the support and the drill boom mounting surface, eliminating gaps caused by machining marks, and guaranteeing verticality and coaxiality post-installation, thereby enhancing drilling accuracy.
Galvanized Fastener Mounting Points:
Bolt hole locations and contact surfaces are galvanized. The zinc coating provides sacrificial anode protection, preventing thread seizure due to corrosion and facilitating easier disassembly during future overhauls, avoiding stripped threads or removal difficulties.
