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.
