【正文】 作用是提升鏟斗并使之與車架連接；轉(zhuǎn)斗油缸通過搖臂——連桿(或托架)使鏟斗轉(zhuǎn)動。1. 裝載機工作裝置設(shè)計概述 裝載機工作裝置設(shè)計概述 裝載機鏟掘和裝卸物料的作業(yè)是通過工作裝置的運動實現(xiàn)的。常見的有關(guān)輪式裝載機的工作裝置設(shè)計中，廣泛采用反轉(zhuǎn)六連桿機構(gòu)為例進行設(shè)計以及放平性、工作強度的校核，本次設(shè)計中在沒有同類正轉(zhuǎn)機構(gòu)設(shè)計資料的前提下，反復(fù)琢磨工作裝置的工作原理，并使用機械設(shè)計軟件AUTOCAD 進行工作裝置的各鉸接點的設(shè)計，所以在進行有關(guān)校核時直接應(yīng)用繪圖尺寸，可以保證精度要求，此設(shè)計資料也可以作為今后正轉(zhuǎn)工作裝置的設(shè)計參考。第二三代產(chǎn)品主要是對工作裝置進行優(yōu)化，改變外觀造型。ZL40／ZL50裝載機，主要裝載機生產(chǎn)廠家均擁有該產(chǎn)品。綜合國內(nèi)外裝載機工作裝置的結(jié)構(gòu)型式，主要有七種類型，即按連桿機構(gòu)的構(gòu)件數(shù)不同，分為三桿式、四桿式、五桿式、六桿式和八桿式等；按輸入和輸出桿的轉(zhuǎn)向是否相同又分為正轉(zhuǎn)和反轉(zhuǎn)連桿機構(gòu)等。裝載機作業(yè)時工作裝置應(yīng)能保證：當(dāng)轉(zhuǎn)斗油缸閉鎖、動臂油缸舉升或降落時，連桿機構(gòu)使鏟斗上下平動或接近平動，以免鏟斗傾斜而撒落物料；當(dāng)動臂處于任何位置、鏟斗繞動臂鉸點轉(zhuǎn)動進行卸料時，鏟斗傾斜角不小于45176。動臂與車架、動臂油缸鉸接，用以升降鏟斗。整個工作裝置鉸接在車架上。它是一種作業(yè)效率高、操作輕便、用途廣泛的施工機械，它不僅用來對松散的堆積物料進行裝、運、卸等作業(yè)，還可以鏟裝爆破后的礦石以及對硬土進行輕度挖掘，并能用來進行清理、刮平場地及牽引等作業(yè)。Move the arm from most the bottom position arrives the biggest unloading to raise to rise the process inside highly, guaranteeing the container the inside the material do not spread to fall。The oil a piston route of travel is the best value。在工作循環(huán)中速度與加速度變化合理；油缸活塞行程為最佳值；工作裝置運動平穩(wěn)、無干涉、無死點、無自鎖；動臂從最底位置到最大卸載高度的舉升過程中，保證鏟斗中物料不灑落；在卸載后，動臂下放至鏟掘位置鏟斗能自動放平。輪式裝載機在作業(yè)時，靠改變液壓缸的長度來使鏟斗獲得所要求的收斗角和卸料角。雖然現(xiàn)在市場上的裝載機已經(jīng)日趨成熟，但對其進行改進設(shè)計仍有非常重要的意義，尤其是裝載機的工作裝置。國外裝載機發(fā)展迅速，而我國裝載機在設(shè)計上存在很多問題，其中主要集中在可靠性、結(jié)構(gòu)設(shè)計強度等方面。太原科技大學(xué)畢業(yè)設(shè)計說明書（2008屆）ZL50裝載機反轉(zhuǎn)單連桿工作裝置設(shè)計學(xué)生姓名 學(xué) 號 院 系 專 業(yè) 指導(dǎo)教師 日 期 ZL50裝載機反轉(zhuǎn)六連桿工作裝置設(shè)計摘 要裝載機是工程機械的主要機種之一，廣泛用于建筑、礦山、水電、橋梁、鐵路、公路、港口、碼頭等國民經(jīng)濟各部門。本文中參閱了大量的土方機械的設(shè)計參考書，其中大多數(shù)是有關(guān)裝載機方面的，有的是工作裝置單一構(gòu)件的設(shè)計，有的則是整個工作裝置的設(shè)計，并且有許多有關(guān)工作裝置優(yōu)化設(shè)計方面，各參考所涉及到的裝載機雖然型號不同，研究的方法也有差異，但綜合起來基本上也概述了現(xiàn)行的設(shè)計方法。而工作裝置對于裝載機來說又是重中之重，所以工作裝置的設(shè)計好壞直接影響到裝載機的使用壽命以及工作效率等。裝載機工作裝置的轉(zhuǎn)斗六連桿機構(gòu)是由與液壓缸，鏟斗相關(guān)聯(lián)的兩個四連桿機構(gòu)組合而成。機構(gòu)中各桿件長度及其結(jié)構(gòu)參數(shù)確定后，需要對該機構(gòu)作某些特定計算，以判斷機構(gòu)設(shè)計的正確性。關(guān)鍵詞 工程機械，裝載機，工作裝置The Turn Withershins 6link Work Equipment Design of ZL50 Wheel LoadersAbstractThe loader is one of the main kind of the engineering machinery, used in every department of national economy such as the building , mine , water and electricity , bridge , railway , highway , port , quay extensively. In this article has referred the massive folk recipes machinery design reference book, majority is the related car loader aspect, some are works the equipment sole ponent design, some then is the entire work installment design, and has many related work installments optimization design aspect, each reference involves to the car loader although the model is different, the research method also has the difference, but synthesized basically has also outlined the present design method. The overseas loader development is rapid, but our country car loader has very many problems in the design, mainly concentrates in aspect and so on reliable, structural design intensity. But works the installment regarding the loader to say also is extremely important, therefore the work installment design is good and bad affects directly the car loader service life as well as the working efficiency and so on . Although in the present market car loader already day by day was mature, but carried on the improvement design to it still to have the extremely vital significance, in particular loader work installment.
