AI Technical Summary

Technical Problem

Existing hoisting and alignment methods lack systematic modeling and process control in the hoisting of large-span arched corrugated steel plates, resulting in reduced hoisting and alignment accuracy and easily causing irreversible assembly path problems due to friction, local contact, and initial tightening.

Method used

By establishing a unified coordinate system for corrugated steel plate components, a coordinate system for joint edges, and a coordinate system for hole groups before hoisting and rigidly binding them, an impedance-controllable hoisting state and reversible corridor constraints are constructed. Micro-vibration patches and micro-displacement targets are used to obtain interface reversibility fingerprints. Combined with lateral bypass correction and the automatic yielding mechanism of flexible guide bodies, the dynamic assembly process is controlled.

Benefits of technology

It improves the accuracy of hoisting and positioning of large-span arched corrugated steel plates, avoids irreversible assembly paths, ensures construction safety and assembly efficiency, and enhances positioning robustness and reliability.

Abstract

The application provides a large-span arched steel corrugated plate hoisting alignment method and device, and relates to the field of data processing. In the method, before hoisting alignment, a steel corrugated plate component coordinate system, a joint edge coordinate system and a hole group coordinate system are constructed and rigidly bound to unify the alignment reference; impedance controllable hoisting and reversible corridor constraints are introduced during hoisting, the constraint state is identified in real time by combining interface reversibility fingerprint, and irreversible constraints are avoided by lateral detour; stable insertable window center posture is determined by using zero mean limited perturbation and multiple crossing sampling; on this basis, flexible locking is realized by using a flexible guide body, and fastening is realized by combining interface fingerprint gating, thereby realizing stable and high-precision hoisting alignment without overall backoff. The technical solution provided by the application facilitates improving the accuracy of large-span arched steel corrugated plate hoisting alignment.
