AI Technical Summary

Technical Problem

In steel-frame modular buildings, the high-altitude hoisting and docking of vertical beams suffers from low precision, low efficiency, and high safety risks. Especially under the influence of factors such as wind and micro-sway of the crane, it is difficult to achieve millimeter-level precise docking.

Method used

A high-altitude lifting and guiding precise docking system for steel frame modules is adopted, including a crane, an operating platform and a guiding device. Telescopic drive parts and laser positioning technology are used to achieve automatic alignment of the upper and lower steel frames, and buffering and dust removal devices are used to improve docking accuracy and safety.

Benefits of technology

It improves the docking accuracy and efficiency during steel frame installation, reduces safety risks, ensures the efficiency, accuracy and stability of vertical beam docking, and reduces manual intervention.

Abstract

The invention relates to the technical field of steel frame structures, in particular to a steel frame module high-altitude hoisting guiding precise butt joint system and method, and the system comprises a crane, an operation platform and at least four guiding devices. The crane is used for hoisting the upper-layer steel frame to the position above the lower-layer steel frame for butt joint installation. The operation platform is mounted on the lower-layer steel frame; the four guiding devices are arranged on the periphery of the operation platform and used for adjusting the position of the upper-layer steel frame in the horizontal direction. The guide device comprises a guide seat and a telescopic driving piece; the guide seat is slidably arranged on the operation platform and located on the outer side of the upper-layer steel frame, and the driving part is used for driving the guide seat to slide; the four telescopic driving pieces of the four guiding devices are used for driving the four guiding bases to slide on the operation platform correspondingly so that the four guiding bases can abut against the four outer side faces of the lower-layer steel frame correspondingly. The butt joint device has the effects that the butt joint precision, quality and efficiency during steel frame installation are improved, and the safety risk is reduced.
