[Abstract]:As a new type of super-large equipment hoisting technology, hydraulic hoisting technology is widely used in metallurgical construction industry. As the core equipment of large steel plants, rolling mill plays a key role in the quality and output of the products produced. This paper puts forward higher requirements for the installation accuracy of rolling mill, in which the lifting of mill arch has some complexity and dangerous characteristics and difficulties. This paper summarizes the technical principle of hydraulic lifting system, synchronous control technology, the technology principle of computer control system and hoisting mill arch and the key points of operation in hoisting construction of rolling mill arch, and combines with the characteristics of practical engineering. This paper puts forward the construction method of hoisting construction with hydraulic lifting device and the relevant safety measures, through the calculation of temporary supporting structure, the calculation of hoisting fixture, the analysis of the stability of column, To ensure the safety of the construction process and ensure that the effect of the construction can meet the design requirements, the punching capacity of the concrete foundation of the replacement roll pit bottom slab is checked and so on. The research on hoisting technology of hydraulic lifting device has solved the problem of large equipment hoisting fundamentally. The technology has the advantages of easy operation, stable work, safety, and saving construction cost. The advantages of shortening the construction period make up for the shortage of crane lifting weight greatly and can not meet the shortcomings of hoisting operation. It has an important reference function for the installation of super large equipment in metallurgical industry and other fields in the future.
