绞车设计说明书.doc

摘 要 回柱绞车主要是用来回收液压支柱的小型机械设备，特别适用于中厚煤层和急倾斜煤层采煤工作面及顶板压力较小的采掘工作面，以及在各种采煤工作面上回收沉入底版或被矸石压卡住的单体液压支柱，同时作一般的牵引之用，但回柱绞车多为单速、单一牵引力慢速绞车，作牵引工作时工作效率低。针对回柱绞车牵引工作时，速度慢的缺点，进行JHS-14型双速回柱绞车的设计，该设计采用一级蜗杆减速器传入，在二轴上采用花键配合牙嵌离合器，并在停车时通过操纵手柄直接操纵牙嵌离合器实现绞车快、慢两种速度，两种牵引力传入三级直齿，最终传入卷筒。其采用牙嵌离合器，该离合器的结构简单，零件数量少便于操纵的特点，实现了设计任务要求，又可以在牵引搬运物料时提高工作效率，这样扩大了绞车的应用范围实现了一机多用。 关键词 回柱绞车 蜗杆减速器 牙嵌离合器 Abstract Awapping winch is used to Recovery Hydraulic Prop small-sized mechanical equipment, especially suitable vertical groove coal seam medium-thickness seam steep coal seam coal face and roof hallucal little hallucal extracting coal face, andevery kind of coal face?recoveryDriven cast in place pile with soil drawn out dirly, simultaneouscan also be use of makes general traction, the intrinsic swapping winch JH model number swapping winch most of slow winch,,butslow winch makes general ?traction will be decreased mechanical efficiency.JH of the original series back to winch more than a single-speed, single traction slow winch, for general traction will reduce efficiency,Returns in view of the original JH series when the column winch transporting tows, the speed slow shortcoming, to JHS-14 returns to the column winch to carry on the redesign, uses the first-level worm reducer to spread, uses the spline fit claw clutch on two axes, and when parking realizes quickly, the slow two kind of speeds through the control handle direct control claw clutchs different position, two kind of forces of traction spread to the third-level straight tooth to spread to the reel finally. It uses the claw clutch, this couplings structure is simple, components quantity little is advantageous for the operation the characteristic, has realized the task of design request, may also when the traction transport material raises the working efficiency, like this expanded winchs application scope to realize one machine multipurpose.
