1、液压抓斗式矿井水仓清淤机摘要矿井水仓是煤矿安全生产,防止矿井水灾的重要设施,水仓通常分隔为主仓和副仓,两者轮换清理使用。随着矿井开采深度增大和涌水量增多,水仓内淤积了大量的淤煤,而水仓容积有限,故而必须定期清理。目前多数煤矿采用人工方式清理,工人们站在煤泥水中,用铁锹及桶刮等方法把煤泥清挖出来,再将煤泥运到附近巷道两旁堆放,待煤泥晾干后再运送上地面,或是将煤泥直接装入矿车中运送到地面。人工清挖不仅劳动强度大,作业效率低,而且清仓周期长,特别在雨水季节还可能会因水仓清理不及时而导致淹井事故。本文在对现有清仓方法和国内
2、生产或试制过的各种水仓清理设备进行分析研究的基础上,结合液压传动,抓斗起重机械的结构和工作原理介绍了一种用于清理煤矿水仓淤煤的新型水仓清理设备。该设备采用抓斗抓取提升淤煤的工作方式,抓斗的开合及提升全部通过液压缸来实现,抓斗的前移后退及左右移动通过由马达驱动的大小车行走机构带动车架来实现。该设备具有结构简单、动力系统单一,便于安装维护的优点。90关键词:矿井水仓液压抓斗清淤设备ABSTRACTWharfcoalminewaterissafeproduction,theminefloodpreventionessen
