内容简介：

摘 要目前，矿山广泛使用的JH系列回柱绞车多是由JM慢速绞车演变而来的，具有速度低、结构紧凑、牵引力大等特点。主要应用于煤矿井下采煤工作面回柱放顶之用，同时也可用于上山、下山、平巷等综采工作面设备的搬迁。由于它的高度较低重量又轻，特别适用于薄煤层和急倾斜煤层采煤工作面，以及各种采煤工作面回收沉入底板或被矸石压埋的金属支柱。本次设计的JH-14型回柱绞车是在我去年毕业实习时所实践的回柱绞车的基础上，再查阅参考有关资料后结合我的一些想法所设计的。在减速器的设计过程中，主要采用了蜗轮蜗杆传动、双联滑移齿轮传动、圆柱齿轮传动等传动方式，利用拨叉拨动小滑移双联齿轮的方式来实现变速，而且在拨叉的设计中，我采用了手柄摇动转盘的方式来实现拨叉的水平移动。在设计卷筒时，考虑到卷筒设计精度要求不太高，因此将以往的卷筒通轴改为在卷筒两端利用过盈配合及焊接的方式来分别固定轴，避免了材料的浪费。本次的设计主要特征就是能实现变速，既能满足不同环境下绞车的使用，也实现绞车在回绳和放绳时可以利用不同的速度达到快速回柱。关键词：JH-14回柱绞车； 双联齿轮； 变速ABSTRACTAt present, JH prop-drawing winch which evolved from JM Slow Speed Winch is widely in mine. This machine with advantage of slow speed, compact structure and big traction force. The prop-drawing winch is mainly used to prop drawing and caving roof in coal working face, but also can be used to relocate the equipment in fully mechanized coal face,such as uphill, downhill, and level gallery working face. Because of its low height and light weight, The prop-drawing winch is suitable for the thin coal seam and steep coal seam, and recovering the various metal pillar which Sinking into the floor or buried by gangue.The JH-14 prop-drawing winch is designed based on my Practice on graduation practice last years and consulting large numbers of information, Which also combines many of my new ideas. The design process in the speed reducer, mainly used in the worm-gear transmission, double-slip gear transmission and column gear transmission etc transmission way. slide the small double-gear with the fork-lever to achieve Speed Change. But also in the fork-lever of the design, I used the handle shake rotary table to achieve the fork-lever horizontal movement. The prop-drawing winch drum in the design, taking into account the design precision need not too high,so I put a drum axis change into connection of drum and axis with interference fitting and welding in Both ends of the drum, reduced the Materials of axis, to avoid the waste of materials.The main features of the design is to achieve speed change, it can satisfy the different working environment, but also to make the prop-drawing winch use different speeds to achieve the rapid ret
