摘  要
电动葫芦是起重设备中最常见的一种设备，电动葫芦的发展也决定着起重设备的发展。电动葫芦设计技术在中国现在已经是一种比较成熟的技术了，但与国外的一些技术相比却比较落后。本论文主要是对电动葫芦的起升系统进行了设计。起升系统主要有卷筒、套筒、钢丝绳以及其他辅助元件组成。卷筒是起升系统的主要组成部分，电葫芦减速器的输出转矩通过中间部件传递给卷筒，卷筒发生转动，使固定在卷筒上的钢丝绳绕卷筒进行缠绕，最终带动重物做上下直线运动，实现吊重物的目的。套筒的作用是固定变速器和电动机，实现卷筒的空间定位。并且套筒也是实现电动葫芦悬挂的关键部件。
本文主要做了以下的工作，机构工作级别的选择、钢丝绳的选用、卷筒的设计、套筒的设计以及卷筒上的辅助元件的设计。

Abstract
Electric hoist lifting equipment is the most common form of equipment, the development of electric hoist also determines the development of lifting equipment. Electric hoist design technology in China is now a relatively mature technology, but compare with the foreign technology ,it is still relatively  backward. In this paper, mainly for electric hoist lifting system design. Rise system is mainly consist of reel, sleeve, wire rope and other auxiliary components. Reel Lifting system is the main component of the electric hoist ,electric hoist reducer output torque transfer components through the middle to reel, then reel begin turn to move  so that a fixed rope on the reel for winding around the reel, and ultimately lead heavy objects up and down linear motion , to achieve the purpose of hanging weights. The role of the sleeve is fixed transmission and electric motor ,to achieve the positioning of reel. And the sleeve is also a key component to carry out electric hoist hang.
This paper mainly do the following work, the choice of working-level agencies, the selection of wire rope, drum design, sleeve design, as well as reel on the design of the supporting components.
