门式斗轮堆取料机活动梁卷扬驱动的技术改进

Technical improvement on winding drive of movable beam of portal-type bucket wheel stacker-reclaimer

MDQ3000/3000.650型门式斗轮堆取料机活动梁卷扬驱动部位存在不足,引起卷扬机构故障,从而严重影响着大机的安全。为解决这一问题,将原设计双齿式联轴器更换为带制动轮的鼓形齿式联轴器,并对原减速器进行了改进。经过近一年时间的运行观察,改进后的卷扬驱动部位运行可靠、平稳,故障率为零。

The insufficiency in the winding drive of movable beam of MDQ3000/3000. 650 portal-type bucket wheel staeker-reelaimer may cause winding mechanism failure, hence to seriously threaten the whole equipment safety. To solve this problem, the original designed double-gear coupling is replaced with drum-type gear coupling with brake wheel, with improvement on the original reducer. Throughout the operation observation for nearly one year, it shows that the improved winding drive is provided with reliable and stable operation, and a zero failure rate.
