矿用回柱绞车，又称慢速绞车,是用来拆除和回收矿山回采工作面顶柱的机械设备的提升机。牵引力大和牵引速度慢是矿用回柱绞车的主要性能。现阶段，我国煤矿工业正以日新月异的速度发展。在井下回采工作中，当一个工作面的煤层开采完了以后，就要进行放顶。由于回柱作业属危险性工作，工作人员不能直接进入回柱空顶区，而且金属成本较高，液压支柱若不收回，则必然造成极大的浪费。如果人工回收支柱，安全性差、效率也很低。此时可把回柱绞车布置在距回柱空顶危险区段较远的安全地段，用钢丝绳钩头来拉倒和回收顶柱。由于它的高度较低重量又轻，持别适用于薄煤层、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杖。回柱绞车除可用来回柱放顶工作外，也可用来拖运重物和调运车辆等。使用回柱绞车回收既经济，又迅速，符合现代化工业生产的高生产率和先进的技术经济指标。
根据矿山机械的特殊要求，本文重点设计齿轮传部分和卷筒部件与制动器部件，两个部件是提升机的关键部分，卷筒强度不够导致的直接后果就是筒壳被压溃、焊缝开裂等；制动器是绞车的制动装置，制动装置的作用是克服和抵消提升机运动系统的惯性力，使之停止运动；以及在系统处于停止状态下时，制动系统可能由于重力作用产生的运动。总之，是为了制动提升机的运动，使之处于停运状态的一些设置。

Abstract
Mine recycling mainstay winch, which is also called slowly winch, it is widely used to dismantle and recovery the coal mining machinery and equipments, larger traction engine and slowly speed are the main properties of the recycling mainstay winch. Currently, our country's coal mining industry is developing rapidly,In the work of underground coaling， we will release top-coal when a place of work after the coal mining. Due to the recovery of hydraulic prop assignments, workers cannot risk directly into the whole area, prop-pulling， And the high cost of metal， If hydraulic prop cannot be recovered, It will cause a larger waste. If using artificial recycling hydraulic props, It is poor safety and low efficiency。This can be arranged in winch is empty section top prop-pulling far safer ground, use rope hook head to pull down and recycling spots. Because of its low weight light, it is very  applicable in the thin coal seam, and steep coal seam mining face, and various mining face slab or sink recycling waste metal staff of pressure. Prop-pulling hoist can recycle hydraulic prop，release top coal ,it is also available to transfer the weight and the transport vehicles, etc. It is economic and quickly to use prop-pulling hoist to recycle hydraulic props, It complies with the standards of modern industrial's high productivity and advanced technical economic indexes.
According to the special requirements of mining machinery, This article mainly design gear-transmission, drum brake parts and roll-cylinder, two parts is the key part of the hoist, insufficient strength to block the direct consequence of cylinder shells were crushing, weld cracking, etc. The brake is hoist brake, brake is overcome and offset machine movement of the inertial force system, stop motion, And in the system to a standstill, braking system may be due to the gravity of movement. Anyhow, in order to brake, the movement of some lines in the state.
