建筑砌块-自动窑车系统 摘 要 QMY型系列砌块成型设备，主要用于生产混凝土小型空心砌块。混凝土空心砌块的推广及应用，不仅解决了目前社会大量工业废渣占地和污染环境等问题，而且替代粘土砖，解决了大量浪费和破坏土地资源的问题。 砌块机机体采用超强型钢结构及特殊焊接技术，大量采用进口原材料和高品质电器、液压原件，保证了设备在长期高负荷运转时性能更加稳定、可靠QMY type series block molding equipment, mainly for the production of concrete small hollow block.The promotion and application of concrete hollow block, which not only solve the current social a lot covers an area of industrial waste residue and such problems as environmental pollution, and replace the clay brick, solve the problem of a large amount of waste and destruction of land resources. Block machine body adopts super steel structure and special welding technology, a large number of imported raw materials and high quality electrical, hydraulic parts, ensure the equipment performance in long term high load operation is more stable and reliable. This design mainly is how kiln car system movement, positioning and its transport and implemented a series of fully automated process.Advanced technology, work closely with machine, electricity, liquid, interlock, monitoring, process control, to make it complete the full automation of the kiln car system.The whole production line of a full set of equipment, the use of industrial programmable controller (PLC) control, industrial high reliability, less and operating personnel, labor intensity is low, productivity is high, the comprehensive economic benefit is good. Keywords: full automatic block production lines blocks PLC programming process control hydraulic transmission 目 录 摘 要 I Abstract II 第一章 概述 1 1.1目的和要求 1 1.2选题原则和意义 1 1.3全自动砌块生产线简介 1 1.4本课题的主要任务─自动窑车 2 1.5全自动砌块生产线的主要特点 2 1.6操作规程及主要故障原因 3 第二章 总体设计 5 2.1引论 5 2.2总体方案的确定 6 2.3生产线流程的确定 7 2.4大小车行走机构的确定 7 第三章 窑车系统设计 10 3.1窑车概述 10 3.2窑车系统的动作过程 10 3.3窑车机构的总体设计 11 3.4窑车机构总体性能 12 3.5窑车传动系统方案的确定 12 3.6窑车机构传动形式的选择 13 第四章 零部件的选择与计算 14 4.1 总体参数的选择与计算 14 4.2链轮的选择计算 16 4.3主动轴的设计计算 20 4.4轴的结构设计 20 4.5轴的细部结构设计 23 4.6键的强度校核 24 4.7 滚动轴承的选型及校核 24 4.8选择轴承型号 25 4.9轴承的材料、特点 25 第五章
