Research On The Application Of Hydraulic Lifting Device In Hoisting Of Rolling Mill Arch

As a new type of super large equipment hoisting technology,hydraulic lifting device is widely used in metallurgical industry.Rolling mill is the most important equipment in the steel plant,and plays a key role in the quality and output of the products produced.the requirement of the precision of rolling products is higher.It has some characteristics and difficulties of complexity and danger in the lifting of rolling mills.Based on the references at home and abroad,summarizes the hydraulic jacking system of jacking technology principle,synchronous control technique,computer control system and process principle of lifting rolling mill and rolling mill hoisting operation points during construction;According to the specific engineering characteristics,the construction method and relevant safety measures are put forward;Through the calculation of temporary support structure,the calculation of hoisting jig,stability analysis of column,the checking of punching and shearing capacity of roll changing pit bottom slab and concrete foundation,the safety of construction process is guaranteed,At the same time,ensure that the construction effect can meet the design requirements,and provide reference for similar projects?Hydraulic lifting device of the lifting technique appears to solve the problem of large equipment hoisting fundamentally,this technology has the advantages of convenient operation,stable operation,safety,saving construction cost,shorten construction period,large equipment for future metallurgical industry and other fields have important reference.This technology will play an important role in the hoisting of super large equipment.Compared with the traditional crane hoisting mill arch technologies,the hydraulic jacking device has higher hoisting safety,more convenient operation,simpler equipment assembly,more labor saving,and greatly compensates for the disadvantages of crane lifting.This technology can fully improve the competitiveness at home and abroad,and make outstanding contributions to metallurgical construction and related industries.
