起升液压缸装配图-A0
摘要
我们在搬运物料的时候会用到叉车，其中重式的平衡叉车用得很多，这一类叉车常常会用到厂区，矿区、仓库、车站、码头港口等等地方，主要是为了搬运转移那些大型的、成件包装的或者托盘等等集装好的物件，可以进行装卸物件、堆垛物件或者用来短距离的转移货物。叉车里面最重要工作部分是它的液压系统，液压装置可以操控着负荷去做抬升下降、倾斜、侧移等等动作。
这次主要是把平衡重式叉车的液压控制系统设计出来，先是介绍了叉车发展的现状以及行业的背景，它的用途，分析之后确定液压系统最适合的一个方案，在液压控制系统的原理图里确定出基本的运行回路；接下来设计出控制的油路，经过计算选出适合的液压泵型号、不同类别的控制阀门，确定系统需要的辅助元器件；最后用CAD软件画出系统工作的原理图、液压缸的总装图纸等等。
这次设计要把大学四年学到的专业知识进行整合，对于平衡重式叉车的构成方案，我们会从机械设计入手，设计它的液压控制部分，确定好相关的工艺加工流程，让叉车工作起来更安全可靠，工作的效率更高，转换起来更加灵活等等，整个设计要符合相关理论达到它需要的价值。

Abstract
We use forklifts when handling materials, and the heavy balance forklift is used a lot. This kind of forklift is often used in factories, mining areas, warehouses, stations, docks, ports and other places, mainly for handling and transferring large, packaged or palletized objects, which can be loaded and unloaded Stacking objects or transferring goods over short distances. The most important part of forklift is its hydraulic system. The hydraulic device can control the load to do lifting, lowering, tilting, lateral movement and so on.
This time, we mainly design the hydraulic control system of the counterweight forklift. First, we introduce the development status of the forklift, the background of the industry, and its use. After analysis, we determine the most suitable scheme of the hydraulic system, and determine the basic operation circuit in the schematic diagram of the hydraulic control system; Next, the control oil circuit is designed. Through calculation, the suitable hydraulic pump model and different types of control valves are selected, and the auxiliary components required by the system are determined; Finally, CAD software is used to draw the schematic diagram of the system and the general assembly drawing of the hydraulic cylinder.
This design should integrate the professional knowledge learned in four years of University. For the composition scheme of the counterweight forklift, we will start with the mechanical design, design its hydraulic control part, determine the relevant process flow, so as to make the forklift work more safe and reliable, work more efficiently, and convert more flexibly, The whole design should be in line with the relevant theory to achieve the value it needs.
Key words: forklift, hydraulic system, oil circuit, hydraulic pump; control valve
