摘 要
通過上網(wǎng)瀏覽起重機械方面的資料,以及在老師的指導(dǎo)下對哈爾濱起重機械廠生產(chǎn)的各種起重機的觀察和了解,對國內(nèi)外現(xiàn)有的全路面起重機技術(shù)及發(fā)展現(xiàn)狀有了深刻的了解和認識。這次設(shè)計正是在原有全路面起重機技術(shù)和特點的基礎(chǔ)上,科學(xué)分析起重機械行業(yè)的發(fā)展方向,進一步完善了全路面起重機,從而滿足國家對采用新技術(shù)和新材料的要求。為了充分發(fā)揮起重機的作用,擴大其使用范圍,這次設(shè)計的起重機全都采用液壓傳動方式。起升機構(gòu)、變幅機構(gòu)、回轉(zhuǎn)機構(gòu)和行走機構(gòu)都有各自的液壓馬達或液壓缸,吊臂采用箱形伸縮臂式結(jié)構(gòu),為了增大起重機在起重作業(yè)時的穩(wěn)定性和不傾翻,在起重機上安裝了支腿。
由于實踐經(jīng)驗的欠缺和知識的局限性,該起重機的實際工作性能及可靠性還有待于實際的檢驗。

ABSTRACT
Through browsing the articals about hoisting machinery on the internet, as well as the observation to Harbin machinery factory’s all kinds of hoist crane produced by under teacher's instruction, I have the profound understanding to the domestic and foreign entire road surface hoist crane technology existing and present situation. This design is based on original entire road surface hoist crane technology and characteristics. And the hoisting machinery profession development direction is analyzed scientificly, the entire road surface hoist crane is consummated further. Thus satisfy the request to use new technical and the new material. In order to display the function fully, exaggerate its using scope, I select the hydraulic transmission method. Lifts organization, the amplitude organization, the rotation organization and walks all to have respective motor or the hydraulic cylinder. The arm uses the box shape expansion and contraction structure. In order to increase the stability of the hoist crane when lifts heavy objects and not to pour out, leg are installed on the hoist crane.
Because short of experience and the knowledge, this practical work properties and the reliability are still waiting for the pratical examination.
Key words: Entire Road Surface; Hoist Crane; the Lift Organization; Hydraulic Pressure; Practice; Development Trend
