摘   要
     双速多用绞车是矿山辅助运输设备的一种，利用钢丝绳循环往复工作，实现井下工作设备的运输功能。因其安装方便、操作简单、投资少、费用低、运输距离长及运输连续性等优势，在煤矿生产中，作为主运输或辅助运输设备占有较大的比例。但是目前煤矿上使用的绞车大部分还处于五六十年代的水平，牵引力小，功能简单，功率小，效率低。尽管一些煤矿对其进行的技术改造，但仍然满足不了当前矿井发展和生产的需要。为了进一步做好绞车的改进工作，本文设计了一种新型的辅助运输设备：JSDB-140型双速多用绞车。
JSDB-140型双速多用绞车主要有电动机、联轴器、变速器、卷筒、底座等组成，整个系统配置的方便灵活，外形尺寸小，使用方便，价格较低等优点受到越来越多矿井的欢迎。创新点在于将沿用多年的纵向排布结构改为横向对称结构，这对于工作空间限制极大的矿井生产带来了方便，给工人操作和运输提供了便利。同时安装绞车底座呈雪橇状，在生产现场自移平稳方便，而且绞车重心低，底座刚性好。
文中首先对绞车运输的现状及其在国内外的发展情况和运输过程中的传动系统图进行了简要说明；其次详细地说明了该绞车的结构特点和减速器传动结构的原理，并对该绞车减速器和滚筒装置中各部件进行设计、计算和校核，经校核计算得出各部件强度均满足要求；附录部分附写了该绞车在井下的安装示意图，该绞车的相关技术参数和轴承、齿轮及配用电器的参数等。

ABSTRACT
Two-speed multi purpose winch is mine auxiliary transport of equipment, the use of rope work cycle, Underground work equipment to achieve the transport functions. Its easy installation, simple operation, less investment, low cost, long-distance transport and transport advantages of continuity in coal production, as the main transport or auxiliary transport equipment account for a large proportion. However, the current use of coal winch most of the 1950s and 1960s is still in the level of traction small, simple and functional, power of small, inefficient. Although some of its coal technology, but still not enough to meet the current mine development and production needs. To further improve winch improvements, the paper design of a new type of large tonnage auxiliary transport equipment : JSDB-140 type Two-speed multi purpose winch
JSDB-140 type Two-speed multi purpose winch is made up of motor, couple, gearbox and reel. the base formed the entire system configuration to facilitate flexible configuration is small, easy to use, the advantages of lower prices, an increasing number of mine welcome. Innovations will be in use for many years is that the vertical arrangement symmetric structure to a horizontal structure, This great work space constraints of mine production brings convenience to transport workers to operate and provide convenience. Winch also installed base was sled-like, in production from the scene to facilitate a smooth transfer, and winch low center of gravity, good rigid base.
Firstly in this text telling the present condition of the winch conveyance which development circumstance in domestic and international and the system diagram carried on conveyance processes of spread and move the synopsis elucidation;Sencondly explaining the structure characteristics of the winch and the principle of the structure`s spreading of the decelerating machine in order and in detail, and designing calculating and schooling pit the decelerating machine and rollers to that winch equip medium each parts. Each parts of strength all satisfy request by schooling and calculating;The appendix part attached emerging that winch under the well of gearing sketch map and the relating technique parameter ,then  the parameters of bearings, wheel gears of that winch and the electric appliances whith matched with the winch etc.
