AI Technical Summary
U-shaped steel supports have problems with unstable sliding connections and insufficient bearing capacity in coal mine roadway support, especially in large-section coal mine roadways or under high surrounding rock pressure, they cannot provide effective support.
An anti-slip rotation connection node is adopted, which connects adjacent arc-shaped steel pipes through sleeve assembly and rotating disk assembly to enhance longitudinal stiffness, and is connected to rotating blades through oblique connecting rods to achieve multi-angle support and prevent slippage.
It improves the overall stability and load-bearing capacity of the steel pipe arch support system, distributes the load evenly, prevents slippage of adjacent steel pipes, and enhances the connection performance of nodes.
