设计简介
摘要
本文简要介绍了混凝土输送泵车的结构和特点，总体设计了混凝土输送泵车的臂架系统并对相关参数进行了计算校核，同时对混凝土输送泵车的设计要点进行了简要说明。本文重点介绍了混凝土输送泵车臂架系统伸缩部分，变幅结构和液压系统的设计。
本次设计主要内容和要求：分析目前混凝土输送泵车的发展状况并设计出具有一定重量的混凝土输送泵车完整的臂架系统，绘制出臂架系统装配图和每节臂的结构图。设计出臂架系统液压系统，绘制臂架系统液压系统原理图。通过分析和计算，确定每节臂的截面尺寸及截面形状，设计每节臂的具体结构和臂之间的连接方式，设计整个臂架系统伸缩方式。并且设计混凝土输送泵车的臂架系统实现起重臂伸缩，变幅所需的上车液压系统，计算选择合适的泵，油缸及阀等液压元件。其中，以伸缩臂的设计最为重要。

Abstract
This article is briefly introduced with the vehicle the hoist crane structure and the characteristic, the system design SQ40ZK3Q 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.
