精品文档---下载后可任意编辑该设计介绍了垃圾搬运起重机的主要组成结构及其各结构的作用。主要对小车和大车的驱动系统，起升系统和桥架进行了优化设计。为了减轻起重机自重，并且使结构紧凑，本设计针对大车，小车不同的驱动要求分别采纳了分别驱动方式和集中驱动方式。驱动系统则统一采纳制动器、减速器和电动机组合成一体的“三合一”驱动型式设计，其中重点在于选择各成品部件，并根据其特性和技术参数选择匹配的小车架。针对起升机构，本设计进行了起升电机，减速器和制动器的选用以及卷筒和钢丝绳的设计和校核，使其满足起重量，起升速度的要求，达到初定的工作级别。桥身采纳偏轨箱形双梁，这样设计的好处在于不仅有效的减轻了起重机整体自重，更能明显得增强桥身的刚度，使桥身不易变形，延长起重机的使用寿命。关键词垃圾搬运起重机；优化设计；驱动系统；“三合一”驱动型式；起升机构；偏轨箱形双梁AbstractThe main structure and its action of bridge waste handling grab crane are designed. Trolley and the bridge truck driving system and the bridge were optimized to alleviate crane weight, and make compact structure. The design adopts the method of being separately driven and being driven together, according to the different requirements of trolley and bridge truck. Driving systerm is made up of braker, reducer and motor, which is the type of three in one. The design focuses on the choice of finished parts, and according to its characteristics and technical parameters, the matching trolley frame is selected. The selection and check of hoist motor, reducer and braker are made. And then the design and check of the rope and drum that meet with requirements of lifting weight and the rate. And then achieve to initial working level. Bridge adopts bias-rail box-beams, the benefits of this design not only is effective in reducing the overall crane weight, but also can increase the stiffness of bridge, which make bright not to deform easily, extend the life ...
