An automatic decoupling device for steel structure multi-section column hoisting

Abstract

The invention relates to a hoisting tool for columns in the installation process of high-rise steel structure buildings, and discloses an automatic unhooking device used in the hoisting process of the columns of a steel structure. The automatic unhooking device comprises two hoisting and bearing hoops and tension adjustment mechanisms and is characterized in that each hoisting and bearing hoop is composed of a long-strip-shaped straight plate and connecting bends which are connected to the two ends of the straight plate and are perpendicular to the straight plate, the connecting bends are provided with axle holes, two hoisting lug plates are symmetrically arranged on each hoisting and bearing hoop, the two hoisting and bearing hoops are arranged in parallel, and one tension adjustment mechanism is connected between the opposite connecting bends of each hoisting and bearing hoop through a rotation shaft hinge. The automatic unhooking device has the advantages of being simple in structure, convenient to use, safe, reliable, high in applicability, convenient and flexible to assemble and disassemble on the site and capable of being recycled, achieving automatic unhooking after hoisting is completed, avoiding the security risk of operation personnel working high above the ground, improving the work efficiency of installing the steel columns, reducing the manpower consumption and the machine consumption and lowering the cost.

Description

technical field [0001] The invention relates to a multi-section column hoisting tool in the installation process of a multi-high-rise steel structure building, in particular to an automatic decoupling device for hoisting a steel structure multi-section column, and belongs to the technical field of hoisting tools for construction engineering. Background technique [0002] The construction and installation of steel columns of existing multi-high-rise steel structure buildings, due to the limitation of production, transportation and on-site lifting capacity, usually adopts the installation method of multi-section steel columns on site, and the steel column sections generally range from 5 to 15 meters. Wait, even longer. The common practice is: temporarily install the positioning lug plate at the butt joint of the upper and lower steel columns, and also serve as the hoisting lug plate. Before the steel column is hoisted, a temporary ladder is added. Open the clasp to separate t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the high labor intensity in the installation process of the multi-section steel column of the existing multi-high-rise steel structure by temporarily installing the positioning ear plate as the lifting lug, and the construction personnel climb to the top of the column to remove the hook through the temporary ladder. , large safety hazards, low hoisting efficiency, etc., provide a steel structure multi-section column that can realize the clamping of the spreader and the steel column and decoupling after hoisting, etc., reduce labor intensity, reduce safety hazards, and improve hoisting efficiency Hoisting automatic decoupling device
