摘   要
     雙速多用絞車是礦山輔助運輸設備的一種，利用鋼絲繩循環往復工作，實現井下工作設備的運輸功能。因其安裝方便、操作簡單、投資少、費用低、運輸距離長及運輸連續性等優勢，在煤礦生產中，作為主運輸或輔助運輸設備占有較大的比例。但是目前煤礦上使用的絞車大部分還處于五六十年代的水平，牽引力小，功能簡單，功率小，效率低。盡管一些煤礦對其進行的技術改造，但仍然滿足不了當前礦井發展和生產的需要。為了進一步做好絞車的改進工作，本文設計了一種新型的輔助運輸設備：JSDB-140型雙速多用絞車。
JSDB-140型雙速多用絞車主要有電動機、聯軸器、變速器、卷筒、底座等組成，整個系統配置的方便靈活，外形尺寸小，使用方便，價格較低等優點受到越來越多礦井的歡迎。創新點在于將沿用多年的縱向排布結構改為橫向對稱結構，這對于工作空間限制極大的礦井生產帶來了方便，給工人操作和運輸提供了便利。同時安裝絞車底座呈雪橇狀，在生產現場自移平穩方便，而且絞車重心低，底座剛性好。
文中首先對絞車運輸的現狀及其在國內外的發展情況和運輸過程中的傳動系統圖進行了簡要說明；其次詳細地說明了該絞車的結構特點和減速器傳動結構的原理，并對該絞車減速器和滾筒裝置中各部件進行設計、計算和校核，經校核計算得出各部件強度均滿足要求；附錄部分附寫了該絞車在井下的安裝示意圖，該絞車的相關技術參數和軸承、齒輪及配用電器的參數等。

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.
