【摘要】：液壓頂升裝置吊裝技術作為一種新型超大設備吊裝技術現廣泛應用于冶金建設行業(yè)。軋機作為大型鋼廠最核心的設備,對于所生產的產品質量、產量起著關鍵性的作用,對軋機的安裝精度提出了更高的要求,其中軋機牌坊吊裝具有一定復雜性和危險性的特點和難點。論文在參閱國內外有關文獻資料的基礎上,總結了液壓頂升系統(tǒng)的頂升技術原理、同步控制技術、計算機控制系統(tǒng)與吊裝軋機牌坊的工藝原理和進行軋機牌坊吊裝施工時的操作要點;結合具體實際工程特點,提出采用液壓頂升裝置進行吊裝施工的施工方法和相關的安全保障措施;通過對臨時支撐結構計算、吊裝夾具計算、立柱穩(wěn)定性分析、換輥坑底板混凝土基礎沖切承載力校核等,保證施工過程的安全性,同時確保施工的效果能夠滿足設計需求,為類似工程提供參考。液壓頂升裝置吊裝技術的研究從根本上解決了超大設備吊裝的難題,該技術具有便于操作、工作平穩(wěn)、安全性、節(jié)約項目施工成本、縮短施工工期等優(yōu)點,大大彌補了行車吊裝起重量不足,無法滿足吊裝作業(yè)的缺點,對今后冶金行業(yè)及其他領域超大型設備安裝具有重要的借鑒作用。
[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.
