目前,白云鄂博铁矿使用最多的是 KY-310A 型牙轮钻机,此类型钻机具有故障率低、操作简单、维护方便、穿孔效牢高等特点。然而,其履带支架存在设计缺陷,轨板磨行程托轮耳板,严重的还磨托轮轴,常常出现行程托轮掉、托轮铜套磨损等故障,严重影响了设备效率的正常发挥,增加了工人的劳动强度。因此,笔者针对这一问题进行深入研究,对履带支架进行了改造,消除了以上设计缺陷,提高了穿孔效率。1存在问题及分析KY-310A 型牙轮钻机在白云鄂博铁矿主矿车间运行十多年,履带支架存在一定的设计缺陷,常出现履带支架托轮轴耳板磨损、托轮轴磨损、托轮轴扣坏及
At present, the most widely used Baiyunebo iron is the KY-310A-type cone drill, this type of drilling rig has the characteristics of low failure rate, simple operation, easy maintenance, high piercing efficiency. However, there are design flaws in the crawler bracket, the runner plate of the runner on the rail plate, and the serious grind wheel axle also often cause trips such as stroke of the runner roller and wear of the bushings of the roller bush, which seriously affect the normal operation of the equipment efficiency and increase The labor intensity of the workers. Therefore, the author of this issue in-depth study of the crawler bracket has been modified to eliminate the above design flaws and improve the perforation efficiency. 1 Existing Problems and Analysis KY-310A Type Drilling Rig operates for more than 10 years in the main ore deposit shop of Baiyunebo Iron Mine. There are some design flaws in the crawler bracket, which often leads to abrasion of the bearing bracket shaft of the crawler bracket, abrasion of the supporting axle, Bad and
