【正文】 本科學(xué)生畢業(yè)設(shè)計 GKT13高位舉升路燈維護車改裝設(shè)計（底盤、液壓部分） 院系 名稱 ： 汽車與交通工程學(xué)院 專業(yè)班級 ： 車輛 工程 學(xué)生姓名 ： 指導(dǎo)教師 ： 職 稱 ： 教授 The Graduation Design for Bachelor39。s Degree The top digit lifting street light maintenance vehicle reequips the design of GTK13 （ chassis， hydraulic pressure part） Candidate： Specialty： Vehicle Engineering Class： B076 Supervisor： Prof. Heilongjiang Institute of Technology I 摘 要 在人們生活水平日益提高的今天，越來越多的高 空作業(yè)問題圍繞著我們，并且困擾著我們，主要的原因是 由于使用的舉升方法既不便捷，也不專業(yè)，更不安全，占用了大量人力、物力，并造成了很多財務(wù)、資源浪費。因此特擬定自行走小型舉升車這樣一個設(shè)計題目，利用所學(xué)習(xí)的知識，借鑒前人的產(chǎn)品，設(shè)計出有特色的專用舉升車輛，從而給人們生活帶來方便。 設(shè)計承擔(dān)的任務(wù)是設(shè)計三類底盤的設(shè)計和液壓系的統(tǒng)設(shè)計，三類底盤的設(shè)計即為橫梁、縱梁的布局，液壓系的統(tǒng)設(shè)計主要完成液壓系統(tǒng)原理、液壓油箱以及支腿機構(gòu)的設(shè)計。機械舉升部分采用三節(jié)舉升臂，利用金屬焊接及銷軸連接組合各臂，使用平行四邊形的四連 桿變形對吊籃進行調(diào)平，通過對液壓系統(tǒng)控制來完成特定的動作；液壓控制系統(tǒng)包括選取液壓缸、控制系統(tǒng)及元件的選擇。 設(shè)計依據(jù)國家標(biāo)準(zhǔn)和機械行業(yè)標(biāo)準(zhǔn)，通過查閱機械設(shè)計手冊等書籍，利用相關(guān)計算公式和材料信息，系統(tǒng)的對機構(gòu)進行了強度校核，驗證了設(shè)計的合理性，確定了各零件的使用材料、外形尺寸和加工方法，并完成了整體構(gòu)架的裝配方案，使機構(gòu)能夠?qū)崿F(xiàn)最大舉升達 。 全套圖紙，加 153893706 關(guān)鍵詞 ：曲臂式高空作業(yè)車；舉升機構(gòu) ； 液壓系統(tǒng)設(shè)計；小型；設(shè)計 II ABSTRACT In people39。s standard of living increased today, more and more aerial problems around us and haunt us, the main reason is due to the lifting method is neither convenient nor professional, more insecurity, which takes A lot of manpower, material resources, and caused a lot of financial, resource waste. Therefore, developing their own special take such a small lift truck design topic, the use of the knowledge acquired, the previous reference products, designed with special features lift vehicle, to bring convenience to people39。s lives. The task is designed for selecting three chassis design of hydraulic design, three types of ec namely for the chassis design of longitudinal beams and the integration of layout, hydraulic design mainly plete hydraulic system principle, hydraulic oil tank, and a leg design of anization. and design of lifting mechanism。 type selection small vehicles from car chassis, lifting mechanism mainly plete mechanical lifting part design and hydraulic control system design. One mechanical lifting part adopts three lifting arm, using metal welding and pin shaft connecting each arm, the use of bination of a parallelogram linkage deformation of the basket, through adjusting hydraulic system to specific action control, The hydraulic control system, including the selection of hydraulic cylinder, control systems and ponents. On the basis of the national standards and design of mechanical industry standard, access to mechanical design manuals, etc, using the formula for calculating the related books and materials, the information system of anization, the intensity of the rationality of the design and use of materials, ponents, the dimensions and processing method and pleted the overall architecture of the assembly, the most heavily to realize that institutions such a height of m.
