Mining U-shaped Pin (Quick Adapter with U Pin)
Definition & Function
A U-shaped pin (or U-pin) is a metal fastener designed for connecting hydraulic hoses or components in mining pipeline systems. It enables quick engagement and disengagement of hydraulic fluid flow, primarily used in environments with plain mineral oil or high-water-content hydraulic liquids18.
Structural Features
U-shaped cross-section: Composed of two arms connected by a bridging rod. The arms are initially convergent and then divergent, allowing them to snap into annular grooves of hose fittings for secure fixation8.
Material: Typically made of steel or stainless steel to ensure corrosion resistance and mechanical strength in harsh mining conditions78.
Industrial Application
Widely used in hydraulic supports for securing pipelines in coal mining equipment.
Critical in systems requiring rapid assembly/disassembly under high-pressure conditions18.
Technical Standards
Governed by MT/T 986-2006, which specifies design, testing, and inspection requirements for U-pin adapters and accessories in mining applications14.
Operational Challenges
Prone to rust due to underground moisture, complicating manual removal. Specialized tools (e.g., hydraulic-driven disassembly devices) are often required to avoid damage during extraction8.
Key Terminology in Context
Alternative Names: U-shaped pin, U-pin quick adapter.
Technical Context: Referred to as "quick adapters with U pin" in the Chinese national standard MT/T 986-20061.
