摘要 單斗挖掘機采用單斗來挖泥土或礦石自行開采由回轉工作臺和行走裝置 斗臂斗桿完全放電尖端放電后的土壤 空桶面臨落后于業(yè)務的周期 在建筑 施工 道路工程 水電工程 農(nóng)田改造 以及軍事工程和露天 開放式存儲 和挖掘 到工作裝置廣泛使用 點反鏟 鏟挖 把握鏟 也叫搶 和斗桿與 其他鉸鏈 由動臂支撐 從下往上 斗齒尖軌跡往往采用弧線行動 停止適 用于開挖面以上的土壤機器 反鏟挖掘機鏟斗和斗桿鉸鏈 挖掘行動通常是 由斗齒向下的軌跡呈圓弧線 適用于向下跌破鏟挖掘機鏟斗下 動臂沿著邊 緣移動 可移動的土壤挖掘手臂在固定位置 在一條直線上斗齒軌 從而能 夠獲得直采工作面 適用于開挖邊坡 溝渠 或平挖掘機鏟斗簸箕形 罐底 部前端裝入桶 在鑄造采掘工作面向外桶 重切斗齒借到土壤中 然后通過 牽引拖鏟挖 用繩子升斗升降 轉臺期滿后挖轉身卸土 挑流鼻坎能向下挖 掘表面以下的土壤卸土 也為水下開采 大范圍的挖掘 開采 但精度鏟挖 掘機鏟斗的兩個或兩個以上的下巴盤鉸鏈 下顎打開閥門組成 扔在采掘工 作面 葉片瓣切成土壤 使用鋼絲繩或液壓缸輪 挖鉗口閥可以卸載基坑或 水下采礦 挖掘也可用于裝載顆粒中常用小型和中型挖掘機 其工作裝置可 左右移動 更換不同的鏟斗 可以不同也被轉換成一臺起重機 打樁機 篡 改 故稱一般 IPS 或地雷司機一般只配備了工作裝置 單操作 因此使用 單斗挖掘機 關鍵詞 單斗挖掘機 礦業(yè)機構 創(chuàng)造性思維 多用的功 Abstract Single bucket excavator using a single bucket digging soil or ore self propelled mining machinery Work by rotary table and walking device etc Homework after the bucket digging bucket full discharge point discharge soil empty bucket faces backward at the cycle of operations Widely used in building construction road engineering water and electricity construction farmland leveling and military engineering and open pit open storage and mining in the yard According to the working device points are shovel backhoe digging shovel shovel grasp the shovel also called grab and other forms Shovel bucket hinge of bucket rod end supported by movable arm the mining action from down to up bucket tooth tip trajectory often arcs stop the machine suitable for excavation surface above the soil Backhoe excavator bucket and bucket rod hinged the mining action are usually made of bucket teeth down on trajectory assumes the circular arc line suitable for the soil excavation down below the surface Digging shovel excavator bucket moving along the edge under the movable arm movable arm in a fixed position bucket tooth track in a straight line thus can obtain straight mining face suitable for excavation slope ditches or flat ground Shovel excavator bucket is dustpan shape bucket bottom front loaded bucket teeth Work casting at mining face outward bucket bucket tooth borrow in heavy cut into the soil and then by traction drag shovel digging digging by ascending rope lift bucket after the expiration of the turntable turned to unloading soil flip bucket can dig down below the surface soil unloading soil but also for underwater mining large range of mining but mining accuracy is poor Grasp shovel excavator bucket composed of two or more jaw disc hinge jaw valve open throw in mining face the flap of the blade cut into the soil the use of wire rope or hydraulic cylinder round in palate digging soil Loosen the jaw valve can be unloaded soil Used for foundation pit or underwater mining digging depth Can also be used for loading grain material Earthworks commonly used in small and medium sized excavators its working device can be moved around change different bucket can be different operations Can also be converted into a crane pile driver tamper therefore calls the general ips excavator Mining or mine drivers generally only equipped with a working device single operations therefore calls for excavators Key words single bucket excavator mining institutions creative thinking multi purpose function 目 錄 緒論 1 第一章 單臂挖掘機反鏟工作裝置介紹 2 第二章 挖掘機手臂的工作設置 4 2 1 動臂的結構形式 4 2 1 1 組合式動臂與整體式動臂相比各有優(yōu)缺點 4 2 2 確定斗桿的安裝形式和鏟斗的結構形式 4 2 2 1 斗齒安裝方式 5 2 2 2 鏟斗的結構形式 5 2 3 設計步驟及參數(shù)選擇 6 2 4 斗型設計 7 2 4 1 鏟斗參數(shù)設計 7 2 4 2 斗型計算 7 2 5 動臂的參數(shù)選擇 8 2 6 斗桿參數(shù)計算 11 2 7 搖桿連桿參數(shù)設計 13 第三章 液壓元件的選擇及系統(tǒng)的計算 14 3 1 主要參數(shù)的設定 14 3 2 鏟斗油缸作用力的確定 14 3 3 斗桿油缸作用力的確定 16 3 4 動臂油缸作用力計算 17 3 5 液壓系統(tǒng)計算 17 3 5 1 液壓傳動計算 18 第四章 強度校核計算 20 設計結論 25 結論 26 參考文獻 27 致 謝 29
