晓南矿成功研制防运输机刮板跳槽装置

晓南矿N1-1402工作面采用GH9-38VE/5.7型刨煤机落煤,配套使用DBT-GH-PF3/822型刮板运输机运煤。运输机机头中部槽由于长时间运行,磨损严重,经常出现刮板跳槽的现象,这会导致刮板横梁及螺栓损坏,中断生产。为了解决此问题,通常采用更换运输机中部槽的方法。但在狭小空间进行更换中部槽作业施工难度较大,且具有一定的安全风险。为改变这种施工方式,晓南矿自行设计并加工了“防运输机刮板跳槽装置”。该装置采用30mm厚铁板加工而成,只需用风钻在运输机一侧打孔安设压脚,再用4根M20*75mm螺栓将装置固定在运输机一侧,就能对刮板起到限位的作用,防止刮板跳槽。

该装置投入使用后,刮板跳槽现象得到有效控制,保证了刨煤机工作面的顺利回采。与更换运输机中部槽相比,加设该装置的成本更低,安装更方便,安全风险更小。
