AI Technical Summary

Technical Problem

In extreme wind environments, the hoisting equipment for suspension bridge trusses suffers from weak wind resistance, poor stability, reliance on manual judgment, delayed adjustments, lack of systematic intelligent control, and insufficient safety monitoring, making it difficult to guarantee hoisting accuracy and safety.

Method used

An intelligent hoisting device was designed, including an attitude adjustment device and an offset adjustment device. It combines a multi-source sensing unit, an intelligent control unit, and a safety monitoring unit to construct a real-time intelligent control closed loop of perception-decision-execution. Through the coordinated action of the attitude hydraulic cylinder and the mass block, it realizes multi-degree-of-freedom active adjustment and real-time wind resistance control of the truss beam.

Benefits of technology

It significantly improves the wind resistance and attitude maintenance of the hoisting system, enhances hoisting accuracy and operational safety, reduces reliance on human experience, and ensures safe and controllable hoisting in extreme wind environments.

Abstract

The invention belongs to the technical field of truss girder hoisting, and particularly relates to intelligent hoisting equipment for a suspension bridge truss girder in an extreme wind environment and a hoisting construction method.The intelligent hoisting equipment comprises a floating crane, and a hoisting tool component is fixedly installed at the lower end of a steel wire rope of the floating crane and comprises a posture adjusting device and an offset adjusting device. According to the intelligent hoisting equipment for the suspension bridge truss girder in the extreme wind environment and the hoisting construction method, by arranging the sling component and integrating the posture adjusting device and the offset adjusting device, multi-degree-of-freedom active adjustment can be conducted on the hoisted truss girder. The offset adjusting device generates reverse inertia force by driving the mass block to move, so that horizontal swinging of the truss girder caused by wind load is effectively counteracted; the posture adjusting device accurately corrects pitching and rolling postures of the truss girder by adjusting the length of the steel wire rope set, and therefore the overall wind resistance stability and posture keeping capacity of the hoisting system are remarkably enhanced in the extreme wind environment.
