【正文】 用較高的許用應(yīng)力,而不需要很高的安全系數(shù),以便減少起重機材料用量 (這并不意味著不安全 ),從而降低設(shè)備的重量和價格。在起重機起升速度、制動器方面的改進,則使用低速運行的起重機吊鉤精確定位,起重機的剎車系統(tǒng)也應(yīng)用微處理進行控制和監(jiān)視工作。德馬克公司最近開發(fā)了一種標(biāo)準車輪箱模塊系列,上面有多組聯(lián)接孔,選用不同型號的驅(qū)動單元,可組裝成臺車,可與金屬構(gòu)件組合后用作橋式、門式起重機或其它軌行式起重運輸機械。根據(jù)市場調(diào)查預(yù)測的統(tǒng)計數(shù)字和積 5 累的資料、圖表、圖線規(guī)律,在嚴密的科學(xué)理論指導(dǎo)下,擬定起重機結(jié)構(gòu)、機構(gòu)、部件等多層次的標(biāo)準化、模塊化單元。增長 20%。目前我國橋式起重機生產(chǎn)廠商有 400 多家,從業(yè)人員 12 萬人,各類橋、門式起重機約有 100 多種型號、上千種規(guī)。而客運專線大量雙線箱梁設(shè)計重量達到 850 噸/片,采用工藝是 “ 先架后鋪 ” ,需要起重量 900 噸以上的架橋機。由于在鐵路客運專線設(shè) 計中橋梁比例增大,而其中 8096 以上又將采用中、小跨度橋梁,即采用整孔預(yù)制的簡支箱梁及小跨度的連續(xù)梁,因此必須重視鐵路橋梁建設(shè)中的施工裝備。 本文內(nèi)容系統(tǒng)新穎、詳略得當(dāng)圖文并茂,有一定的實用價值。 在這片畢業(yè)設(shè)計論文中, 主要介紹了公鐵步履架橋機機架部分的 構(gòu)造與設(shè)計理論和設(shè)計方法。 首先 詳細制定架橋機機架部分的設(shè)計方案, 根據(jù)設(shè)計準則和一般要求,初步確定架橋機的形狀和尺寸。 關(guān)鍵詞:架橋機、機架、橫導(dǎo)梁 、 縱導(dǎo)梁 河北工程大學(xué)科信學(xué)院畢業(yè)設(shè)計 II Abstract Walking frame shop machine a highway and railway bridge key construction equipment, mainly by the longitudinal guide beam, the former auxiliary mandrel, the first leg, the fulcrum of the device, after the fulcrum device, horizontal guide beam longitudinal shift car, the horizontal guide beam, hanging driving beam, sliding track, hydraulic systems, electrical control systems, generator sets and other ponents. This paper introduces the public and iron machine rack part of the walking bridge construction and design theory and design methods. First elaboration of part of the design of erecting machine rack, in accordance with the design criteria and general requirements, initially to determine the shape and size of the bridge machine. Then rack manufacturing quantity, structure, shape and size, the initial development process. Finally, according to the theory of mechanics and mechanics of materials and other related mechanical knowledge, bined with the load requirements for erecting machine, detailed stress analysis and verification of each part of the rack of erecting machine, to ensure the reliability of the bridge machine construction . In this article novel system, appropriate levels of detail illustrated, there are some practical value.
