摘要
載貨汽車(chē)隨車(chē)起重機(jī)是指安裝在汽車(chē)底盤(pán)上,在一定范圍內(nèi)垂直提升和水平搬運(yùn)重物的多動(dòng)作起重機(jī)械，又稱隨車(chē)吊，屬于物料搬運(yùn)機(jī)械，本文簡(jiǎn)要介紹了載貨汽車(chē)隨車(chē)起重機(jī)的結(jié)構(gòu)和特點(diǎn)。本文重點(diǎn)介紹了隨車(chē)起重機(jī)伸縮部分的設(shè)計(jì)，變幅結(jié)構(gòu)的設(shè)計(jì)和上車(chē)液壓系統(tǒng)的設(shè)計(jì)�？傮w設(shè)計(jì)了隨車(chē)起重機(jī)的性能指標(biāo)以及關(guān)于各臂伸縮的原理計(jì)算。并對(duì)隨車(chē)起重機(jī)的設(shè)計(jì)要點(diǎn)進(jìn)行了簡(jiǎn)要說(shuō)明。
本次設(shè)計(jì)主要內(nèi)容和要求：設(shè)計(jì)隨車(chē)起重機(jī)上車(chē)實(shí)現(xiàn)起重臂伸縮，變幅所需的上車(chē)液壓系統(tǒng)，計(jì)算選擇合適的泵，油缸及閥等液壓元件。其中，以臂的設(shè)計(jì)最為重要，對(duì)此作為重點(diǎn)考慮。設(shè)計(jì)出具有一定重量的隨車(chē)起重機(jī)完整的上車(chē)結(jié)構(gòu)，繪制出上車(chē)裝配圖和每節(jié)臂的結(jié)構(gòu)圖。設(shè)計(jì)出上車(chē)液壓系統(tǒng)，繪制上車(chē)液壓系統(tǒng)原理圖。通過(guò)分析和計(jì)算，確定每節(jié)臂的截面形狀及截面尺寸，設(shè)計(jì)每節(jié)臂的具體結(jié)構(gòu)和臂之間的連接方式，設(shè)計(jì)整個(gè)起重臂伸縮方式。

Abstract
This article is briefly introduced with the vehicle the hoist crane structure and the characteristic, the system design with the vehicle hoist crane performance index as well as the principle computation which has expanded and contracted about various arms. And it has carried on the briefing with the vehicle to the hoist crane design main point. This article is introduced with emphasis the hoist crane expands and contracts the partial designs with the vehicle, the amplitude structure design and boards the hydraulic system design.
This design main content and request: Designs has the certain weight the hoist crane integrity to board with the vehicle the structure, draws up boards the assembly drawing and each arm structure drawing. Designs boards the hydraulic system and the plan boards the hydraulic system schematic diagram. Through the analysis and the computation, I determined each arm the section size and the section shape, design each arm between the concrete structure and the arm connection way, the design entire erector beam book expansion and contraction way. And designs the hoist crane to board the realization erector beam to expand and contract with the vehicle, the amplitude must boards the hydraulic system, computation choice appropriate pumping, hydraulic pressure part and so on cylinder and valve Among them, thought especially the arm design is most important, regarding this I with emphasis considered.
Key words ： With the vehicle hoist crane Expands and contracts the arm Hydraulic pressure part
