图书分类号: 密级: 毕业设计( 论文) 桥式起重机大车行进机构设计学生姓名陈振宇学院名称电气信息学院专业名称机械电子工程指导教师张玉林 2015 年 4月 25日毕业设计( 论文) I 摘要当今社会产品更新换代越来越快,为降低生产成本、节约能源、提高生产效率,随着科学技术的发展,先进的电气控制技术和机械技术逐渐应用到起重机械上,使起重机械的自动化程度更加完善、结构日趋简单、性能更加可靠、品种也越来越全。起重机械是以间歇、重复的工作方式,通过取物装置的起升、下降或升降与运移物料的设备。在其工作过程中,经历上料、运送、卸料及返回原处的过程,工作范围较大,危险因素很多。如施工电梯和升降机在用吊笼(或轿厢)输送人员和物料时,被提升在空中的人员、物料等的安全取决于提升钢丝绳和一些安全装置的有效性、可靠性,本文设计一种桥式起重机的大车行进机构的设计,本书收集了有关桥式起重机的各种常用数据和必要的简易计算公式与图表。主要内容包括:起重绳索,辅助工具,电机选择、滑车组,绞车及锚碇,等等。常用数据等关键词:桥式起重机;行进机构;大车机构毕业设计( 论文) II Abstract In today's society, product updates faster and faster, in order to reduce the production cost, save energy, improve the production efficiency, with the development of science and technology, advanced electrical control technology and mechanical technology has been gradually applied to the hoisting machinery, the degree of automation of hoisting machinery is more perfect, the structure es more simple, more reliable performance, variety more and the more full. The hoisting machinery is to batch, repeated work, rise, fall or the lifting and transport of materials through the feeding device of the equipment. In the course of their work experience, feeding, transportation, unloading and return process, scope is larger, the risk factors of many. As the construction elevator and lift in the cage (or car) transportation of personnel and material, was raised in the air, the security personnel of material depends on the hoisting rope and safety device of validity, reliability, design the cart traveling machine this paper designs a kind of bridge crane structure, the book collection a variety monly used data on the bridge crane and simple calculation formula and chart the necessary. The main contents include: the lifting rope, auxiliary tools, motor selection, tackle, winch and anchorage, etc.. Common data etc. Keywords : bridge crane traveling mechanism; cart mechanism; 毕业设计( 论文) I 目录摘要................................................................................................................
