AI Technical Summary
In existing technologies, long-span ultra-high voltage power transmission towers are prone to swaying under wind force, and conventional bolted dampers are difficult to fix during high-altitude hoisting, resulting in inconvenient installation and poor seismic resistance.
The structure employs a reinforced crossbeam and viscous damper. The viscous damper is securely installed through a combination of anti-loosening bolts, auxiliary parts, and welding components. The arc-shaped clamps and welding frames are used for efficient fixing to prevent bolt loosening.
The installation strength of the viscous damper was improved, the seismic resistance of the tower was enhanced, the difficulty of high-altitude operation was reduced, and the stability of the tower was ensured.
