【正文】 河海大學(xué)本科畢業(yè)論文 絞吸式挖泥船定位樁液壓系統(tǒng)設(shè)計(jì) 摘 要 絞吸式挖泥船經(jīng)過一百多年的發(fā)展，已經(jīng)成為挖泥船王國中所占比例最大的船型。絞吸式挖泥船的工作原理 :利用機(jī)械式的挖泥刀具將疏俊區(qū)底部的泥土絞碎，通過船上離心泥泵的旋轉(zhuǎn)產(chǎn)生的真空將挖掘的泥漿經(jīng)吸入管吸入、提升再通過船上排泥管排出的過程。由于絞吸式挖泥船能夠?qū)⑼诰?、輸送、排出和處理泥漿等疏浚工序一次完成，能夠在施工中連續(xù)作業(yè)等優(yōu)點(diǎn)，目前，絞吸式挖泥船被廣泛應(yīng)用于港口、航道的疏浚和陸地吹填工程。它是 一種高技術(shù)含量船型， 定位樁系統(tǒng)是絞吸挖泥船的主要系統(tǒng)之一，結(jié)構(gòu)復(fù)雜，技術(shù)含量高 ，存在大量的設(shè)計(jì)關(guān)鍵技術(shù)和難 點(diǎn)。 本文主要介紹了 “天獅號(hào)”絞吸挖泥船 主要參數(shù) ，絞吸式挖泥船的工作原理和定位樁工作原理。本設(shè)計(jì)的主要特點(diǎn)是：挖泥船 操作容易，同時(shí)還減少了誤操作的可能性，提高了系統(tǒng)的安全性；減少了閥件總數(shù)，系統(tǒng)布置得到了簡化，非常有利于系統(tǒng)運(yùn)行中總效率的提高，能耗降低，也減少了若干設(shè)備投資的費(fèi)用；有利于減少系統(tǒng)的故障發(fā)生率、減少檢測(cè)維修等非作業(yè)時(shí)間，提高了實(shí)際工作的時(shí)效。本設(shè)計(jì)詳細(xì)的闡述了 該定位樁 液壓系統(tǒng)及 各類液壓 元件的 計(jì)算選擇 ， 以及系統(tǒng)的驗(yàn)算過程。 關(guān)鍵詞：絞吸式挖泥船；定位樁；液壓系統(tǒng) 河海大學(xué)本科畢業(yè)論文 絞吸式挖泥船定位樁液壓系統(tǒng)設(shè)計(jì) ABSTRACT The cutter suction dredger after 100 years of development, has bee the largest dredger of the Kingdom of the proportion of the ship. Cutter suction dredger works: Using a mechanical tool to Shu Chun dredging the bottom of the soil area undercooked ground, through the board39。s rotation centrifugal mud pump vacuum to dig the mud by the suction pipe inhaling, raise and then by boat sludge discharge pipe discharge process. As the cutter suction dredger will be mining, transport, discharge and so mud dredging and disposal process once pleted, can the construction of continuous operation and other advantages, at present, a cutter suction dredger is widely used in ports, waterway dredging and Land Reclamation Engineering. It is a hightech ship type, location pile system is a cutter suction dredger one of the major systems, plex, high technology, there are a large number of key technologies and design difficulty. In this paper, for a lion numbers, the main parameters of cutter suction dredger, cutter suction dredger the principle and orientation of pile works. The main features of this design are: dredger, easy to use, while also reducing the possibility of misuse and improve the system39。s safety。 reduce the total number of valves, the system layout has been simplified, the system is very beneficial to the operation of the total efficiency increase, reduce energy consumption and also reduces the cost of certain equipment investment。 help reduce the incidence of system failure, reducing maintenance and other nonoperating test time and improve the actual work effectively. The design detail of the positioning of hydraulic systems and various types of pile calculation of hydraulic ponent selection and system checking process. Keywords: cutter suction dredger。 positioning pile。 hydraulic system 河海大學(xué)本科畢業(yè)論文 絞吸式挖泥船定位樁液壓系統(tǒng)設(shè)計(jì) 目 錄 緒 論 ................................................................................................................................................. 1 第一節(jié) 疏浚工程及絞吸式挖泥船的重要性及意義 ........................................................................... 1 第二節(jié) “天獅號(hào)”挖泥船的參數(shù) .................................................................................................... 2 第三節(jié) 設(shè)計(jì)方法及章節(jié)安排 ......................................................................................................... 4 第一章 絞吸式挖泥船的結(jié)構(gòu)和工作原理 ............................................................................................... 5 第一節(jié) 絞吸式挖泥船的結(jié)構(gòu) ......................................................................................................... 5 第二節(jié) 絞吸式挖泥船特征 ............................................................................................................. 5 第三節(jié) 絞吸式挖泥船工作原理 ...................................................................................................... 6 第二章 工作鋼樁的工作原理 ................................................................................................................ 8 第一節(jié) 定位樁裝置及起落方式 ...................................................................................................... 8 第二節(jié) 定位樁臺(tái)車行走油缸推進(jìn) .................................................................................................. 9 第三節(jié) 液壓系統(tǒng) ........................................................................................................................... 9 第四節(jié) 定位樁液壓缸及液壓系統(tǒng)工作原理 ...................................................................................10 第三章 液壓傳動(dòng)系統(tǒng)的設(shè)計(jì) ................................................................................................................. 11 第一節(jié) 明確設(shè)計(jì)要求 ................................................................................................................... 11 第二節(jié) 分析系統(tǒng)工況，確定主要參數(shù) .......................................................................................... 11 第三節(jié) 擬定液壓系統(tǒng)原理圖 ........................................................................................................17 第四節(jié) 選擇液壓元件 ...................................................................................................................17 第五節(jié) 液壓系統(tǒng)性能驗(yàn)算 ............................................................................................................23 結(jié) 論 ...............................................................................................................................................26 參 考 文 獻(xiàn) ....................................................................................................................................27 致 謝 ...............................................................................................................................................28 附 錄 ...............................................................................................................................................29
