【正文】 統(tǒng)化以及新型化和實用化是這場變革得主題。隨著生產(chǎn)規(guī)模的擴大,自動化程度的提高,作為物料搬運重要設備的起重機在現(xiàn)代化生產(chǎn)過程中應用越來越廣,作用愈來愈大,對起重機的要求也越來越高。橋式起重機可分為普通橋式起重機﹑簡易梁橋式起重機和冶金專用橋式起重機3種。 關鍵詞:橋式起重機,橋架,主梁,端梁,運行機構(gòu) ABSTRACTPairs of beam bridge hoist tool instrument a circulation, intermittence machinery of sport, it is a pairs of beam bridge formed by two case shaped bright beam bridge and two horizontal end pairs of beam bridge .Operate the jackup car and can get up ,hang and carry all kinds of things with the level .It is suitable for all the occasions, such as machining and assembly shop ,warehouse and material.This instruction is mainly to design the roof bean part ,including running mechanism of the cart ,the design of bridge shelf and each part of the inside parts accessory ,assembly store and welding structure .During the course of designing ,consult some relevant materials: the cart adopts different drive scheme ,the end roof beam adopts case shape structure welding by stencil plates ,the connecting end installation of roof beam sets up in the end middle part of the roof beam ,connected by high strength bolted joint through the connecting plate and angle steel .The design of beam bridge shelf mainly refers to weld structure and craft ,and this requires to know something about weld sufficiently and apply the knowledge studied flexibly and correctly . Keyword: The Hoist,End Roof Beam, The Drive前言橋式起重機是一種重要的物料搬運機械。在設計過程中參考有關資料:大車采用分別傳動方案,端梁采用鋼板焊接成箱形結(jié)構(gòu),端梁的安裝接頭設在端梁的中部,并通過連接板和角鋼用高強度螺栓連接。 113.4慣性載荷 113.5偏斜運行側(cè)向力 11 12 123.6扭轉(zhuǎn)載荷 13第四章、主梁計算 154.1內(nèi)力 15 15 16 17 20 22 25第五章、端梁計算 32 32 32 33 37 39 40第六章、主梁和端梁的連接 45第七章、剛度計算 47 47 47 47 48第八章、橋架拱度 49第九章、運行機構(gòu) 49參考文獻 51附錄(論文翻譯) 52致謝 60                          32/5t雙梁橋式起重機橋架結(jié)構(gòu)及大車運行機構(gòu)設計摘要雙梁橋式起重機械是一種循環(huán),間歇運動的機械,它是由兩根箱形主梁和兩根橫向端梁構(gòu)成的雙梁橋架,在橋架上運行起重小車,可起吊和水平搬運各類物件,它適用于機械加工和裝配車間、倉庫和料場等場合。畢 業(yè) 設 計設計題目:32/5t雙梁橋式起重機橋架結(jié)構(gòu)及大車運行機構(gòu)設計姓 名 __ _ _ _學院(系) 機械電子工程學院 _專 業(yè) _機械設計制造及其自動化__年 級 ____班__________指導教師 ______ _ ______學院(直屬系):機械電子工程學院 時間: 2007 年 3 月
