Lifting tool used for fast mounting rolling mill house and application method of lifting tool

Abstract

The invention relates to the field of mounting of large equipment, in particular to a lifting tool used for fast mounting a rolling mill house. The lifting tool is characterized in that the lifting tool comprises a lifting frame and lifting lugs arranged on the lifting frame; the lifting frame comprises an upper transverse beam, a vertical beam and a lower transverse beam; the upper transverse beam and the lower transverse beam are connected through the vertical beam, and therefore the lifting frame is formed; and multiple main lifting lugs are arranged on the transverse side face of the lifting frame, and multiple auxiliary lifting lugs are arranged on the longitudinal side face of the lifting frame. The lifting frame is simple in structure, convenient to use and large in load bearing strength, the lifting process of the rolling mill house can be simplified into the process capable of being completed by simply mounting and demounting several shackles, the lifting time is shortened, and precious time is earned for adjustment of the rolling mill house.

Description

technical field [0001] The invention relates to the field of installation of large equipment, in particular to a spreader for quickly installing a rolling mill archway and a use method thereof. Background technique [0002] The hoisting of cold continuous rolling five-stand archway, hot continuous rolling seven-stand archway, single-stand six-high rolling mill archway, and tempering mill archway. The weight of these unit archways is 65 tons to 180 tons. Many rolling mill archways do not have lifting lugs, and some There are lifting lugs in the design, but the width of the window of the archway is relatively large. Due to the influence of the hoisting space, the use of shorter rigging will interfere with the process of turning and erecting the archway. In view of the above situation, when hoisting the rolling mill archway, the lifting point is often set on the top surface of the rolling mill window, and the steel wire rope or hoisting belt is used to bypass the top surface of...

AI Technical Summary

Problems solved by technology

The top surface of the archway window is the installation surface of the AGC pressing cylinder or the step pad adjustment device. The processing surface has high precision, sharp edges and irregular shapes. During the hoisting process, it is necessary to set up pipe wrapping angles and skids to protect the hoisting rigging. These The implementation of the measures can protect the rigging very well, but it cannot be completely symmetrical during the setting process of the protection measures, which often results in different lengths of the rigging, unsatisfactory verticality after the archway is erected, and in the process of installing the base. Cause unnecessary impact and seriously affect the installation accuracy of the rolling mill base
