废旧轮胎在电铲大臂缓冲装置中的应用

Application of Waste Tyre in Electric Shovel Boom Bumper

在分析原装大臂缓冲装置机构和存在缺陷的基础上,提出了对大臂缓冲装置技术改造,同时分析了改造后的优点,并对大臂缓冲装置在改造前后的故障小时数进行统计分析,验证废旧轮胎作为大臂缓冲装置对减少故障有促进作用,降低了维修成本,可以在各类型电铲上安装运行,同时为矿山生产创造了更多的经济效益。

On the basis of the analysis of mechanism and deficiencies of the old boom root bumper, the improvement of bumper assembly is proposed, and the advantages of the new boom root bumper is analyzed, the statistics of the failure hours of the boom root bumper is analyzed before the improvement and behand it. The anxo-action of reduce the boom root bumper is verified, it is convenient for field repair, the maintenance costs is reduced and more economic has been created for mining production through the improvement.
