AI Technical Summary

Technical Problem

Traditional lifting equipment often uses wire ropes for single-point lifting, which is difficult to resist external forces such as lifting inertia and wind. This can cause the lifting equipment to sway and the corrugated steel plate to shift. Point contact causes the stress to be concentrated at the lifting point, which may cause dents, wrinkles or cracks. In addition, the lifting efficiency is low and repeated operations increase safety hazards.

Method used

The system employs symmetrically arranged arc-shaped hanging plates and magnetic hanging plates. The combination of magnetic and arc-shaped hanging plates increases the contact area, and ball spring pins and fastening bolts ensure a stable connection. Combined with L-shaped alignment plates, it achieves precise alignment, reducing the need for multiple adjustments and repeated operations.

Benefits of technology

It achieves stability and precise positioning during the hoisting process, reduces the risk of spreader swaying and positional deviation, improves hoisting efficiency, avoids component damage and safety hazards, and simplifies the operation process.

Abstract

This invention relates to the field of prefabricated building technology and discloses a hoisting and positioning device for a large-span arched corrugated steel plate structure. The device includes several symmetrically arranged arc-shaped lifting plates, with a corrugated steel plate body placed beneath each of the arc-shaped lifting plates. Corrugated steel plate bodies are fitted with matching magnetic lifting plates on the inner wall of the corrugated steel plate body corresponding to each of the arc-shaped lifting plates. Two sets of pre-embedded hollow bolts are installed on the outer wall of the corrugated steel plate body on both the front and rear sides. This hoisting and positioning device for a large-span arched corrugated steel plate structure effectively solves the problems of traditional lifting tools being unable to resist external forces such as lifting inertia and wind, leading to tool swaying and corrugated steel plate position displacement. Furthermore, point contact concentrates force at the lifting point, causing depressions and wrinkles, affecting the integrity of the component. A single hoisting operation requires multiple lifting, adjustment, and lowering operations, significantly extending the hoisting cycle. Repeated lifting also leads to tool fatigue and wire rope wear.
