文档介绍：履带式起重机构造、原理摘要: 履带起重机是广泛应用于国民经济各领域的一种起重设备,国内在大吨位产品的自主开发方面还是个空白,目前仅有两个厂家引进国外 70年代末的技术有少量的生产, 大部分市场还是由国外产品占领。履带起重机接地面积大,通过性好,适应性强,可带载行走,可进行挖土、夯土、打桩等多种作业。机动灵活,不象固定式起重机那样需要安装和调试。但因行走速度缓慢,转移工地需要其他车辆搬运。本文概述述了起重机的分类,简要说明了履带起重机的各个部分及其工作原理,详细介绍了履带起重机的回转, 卷扬(提升),行走液压系统工作原理。关键词: 履带吊回转卷扬行走液压系统 The Principle Of Hydraulic System Of Crawler Crane Abstract :In china there ’sa blank in the d evelopment of the large crawler crane, which is a important device widely used in different fields. At present , only panies which introduce foreign technology of the end of 1970 product some crawler cranes and the most part of the market is in the hands of other countries . The crawler crane take a large area with ground, has a strong a daptability , can be widely used,and can go with a lifting , in addition ,it can ekcacate,tamp,pile and so on. It’s more flexible, not need to be installed and adjusted. But it goes slowly, no wander it needs a car to help with it to go. T his paper simply show you the c ategor ies of crane, the principle of different parts of the crawler crane. And it is detailed in the hydraulic systems of gyration, lifting, going. K ey words : crawler crane 、 gyration 、 lifting 、 going 、 hydraulic syste m 目录 1引言----------------------------------------------------------------- (4) 2工程起重机的分类----------------------------------------------------- (4) 轮胎式起重机---------------------------------------------------- (4) 塔式起重机------------------------------------------------------ (5) 龙门起重机------------------------------------------------------ (5) 门座起重机------------------------------------------------------ (6) 桥式起重机------------------------------------------------------ (6) 履带式起重机---------------------------------------------------- (6) 3履带式起重机的组成---------------------------------------------------- (7) 履带式起重机概况------------------------------------------------ (7) 履带式起重机的组成部分------------------------------------------ (8) 履带式起重机各部分工作原理--------------------------
