【摘要】：海洋石油平臺、海上風(fēng)電樁基等大型海上施工單位都需要利用大型管樁做為基本搭建單元。由于海上用設(shè)備的大型化,就需要專用起吊設(shè)備實現(xiàn)對海洋用管樁的搬運、操作等工作。目前我國各家海洋開發(fā)公司所使用設(shè)備為從國外高額進口或租賃的,國內(nèi)在該項技術(shù)上尚屬空白狀態(tài)。國外設(shè)備中有一類是通過將吊具置于管樁內(nèi)部,通過自身的外脹作用來夾緊管樁的。本課題來源于海油工程公司級科研項目“內(nèi)脹式吊樁器國產(chǎn)化研制”。論文的研究目的就是研制出具有我國自主知識產(chǎn)權(quán)的這種內(nèi)脹式吊樁設(shè)備,最終產(chǎn)生工程樣機以運用于實際,減少我國海上建設(shè)施工成本。 論文通過對內(nèi)脹式吊樁器的工況進行詳細分析,依據(jù)內(nèi)脹式吊樁器的技術(shù)指標(biāo),制定了總體設(shè)計方案,并且通過分析計算驗證了方案的可行性。圍繞總體設(shè)計方案,對工程樣機通過三維建模,設(shè)計出可以滿足工作要求的具體樣機結(jié)構(gòu)。通過各種理論計算輔以ANSYS有限元強度分析及ADAMS動力學(xué)分析,驗證了所設(shè)計結(jié)構(gòu)滿足工作要求。 論文對內(nèi)脹式吊樁器關(guān)鍵部件鑲嵌壓塊進行了研發(fā)。參照國、內(nèi)外在嵌入式接觸提拉方面的相關(guān)成果,制備了具有較高強度、硬度的鑲嵌壓塊。并且通過理論分析驗證了所設(shè)計鑲嵌壓塊滿足工作要求。 論文最后通過簡化內(nèi)脹式吊樁器工作狀態(tài)模型,建立了簡易試驗裝置平臺。通過對簡易模型的施載,驗證了管樁可以被起吊并被夾持住。試驗結(jié)果為一方面吊具上的鑲嵌壓塊沒有發(fā)生破損,另一方面鑲嵌壓塊與管樁間也沒有發(fā)生明顯的相對滑動。通過此試驗也說明了對于這種帶有尖頂使被夾持材料表面發(fā)生損傷的接觸形式,兩接觸面之間的靜摩擦系數(shù)將達到一個比較大的數(shù)值。
[Abstract]:Large offshore construction units, such as offshore oil platforms and offshore wind power pile foundations, all need to use large pipe piles as basic building units. Because of the large-scale use of offshore equipment, special lifting equipment is required to carry out the handling of offshore pipe piles. Operation and other work. At present, the equipment used by various marine development companies in our country is imported or leased from abroad at a high amount, but the technology is still blank in China. One type of foreign equipment is by placing the hoist inside the pipe pile. This topic comes from Yu Hai oil engineering company grade scientific research project "the domestic manufacture of the internal expansion type hanging pile device". The purpose of this paper is to develop this kind of independent intellectual property right of our country. Intraspecific swelling-type pile lifting equipment, Finally, engineering prototype is produced to be applied to practice and reduce the construction cost of offshore construction in China. Through the detailed analysis of the working conditions of the inner expansion type pile hoisting device, according to the technical index of the inner expansion type hanging pile device, the overall design scheme is established, and the feasibility of the scheme is verified by analysis and calculation. Through the 3D modeling of the engineering prototype, the concrete prototype structure can be designed to meet the requirements of the work, and through various theoretical calculations with ANSYS finite element strength analysis and ADAMS dynamics analysis, it is verified that the designed structure meets the working requirements. In this paper, the research and development of the inlay block of the key component of the inner expansion type pile hoist is carried out. The relative achievements of the reference country and the inside and outside in the field of embedded contact Czochralski are prepared, which have high strength. Hardness of the inlay block. And through theoretical analysis to verify that the design of inlay block to meet the requirements of the work. In the end of the paper, a simple test device platform is established by simplifying the working state model of the internal expansion type pile hoisting device. It is verified that the pipe pile can be lifted and clamped. The test results show that, on the one hand, there is no breakage of the embossed block on the lifting gear. On the other hand, there is no obvious relative sliding between the inlaid press and the pipe pile. This experiment also shows that the contact form with a pointed roof causes damage to the surface of the clamped material, The static friction coefficient between the two contact surfaces will reach a relatively large value.
