【Abstract】Mine scraper conveyor reducer defective form of common faults occurring in the use and maintenance process, scission, off the chain, motor heating and other electrical and mechanical failures, accidents common organic warped head, tail warped, liquid coupling force oil and fire, wounding many forms fall accident on the conveyor. Strengthen the maintenance of the scraper conveyor, adhere to preventive maintenance, so that no less a failure, is the current electromechanical management an important part. Important considerations are the prevention of accidents should be well prepared before starting the inspection work is prohibited by the staff working on the downpipe downpipe or found fault to a power outage overhaul.

1. 前言
(1)刮板输送机是目前国内外缓倾斜长壁式采煤工作面唯一的煤炭运输设备。刮板输送机所以能在采煤工作面中得到广泛应用,是由于它和其它输送机相比具有下述优点:运输能力不受货载的块度和湿度的影响;机身高度小,便于装载;机身伸长或缩短方便;移置容易;机体坚固,能用于爆破装煤的工作面,也能与采煤机和自移式液压支架组成综采工作面。因此,刮板输送机是采煤设备中不可分割的一部分,它能否正常运转,将直接影响工作面的正常生产。
(2)在使用和检修过程中,刮板输送机常见故障形式有减速器出现的故障、断链、掉链、电机发热等多种机电故障。常见安全事故有机头翻翘、机尾翻翘、输送机上夹伤人等多种事故形式。对刮板输送机加强维护、坚持预防性检修,使其不出或少出故障,是当前机电管理中的重要一环。……
