摘要
为满足目前我国煤矿大转矩钻机的检测水平,研制了12 000 N·m大转矩煤矿用钻机试验台,介绍了该试验台的结构及其功能原理,根据钻机技术参数,确定钻机试验台测试参数,并通过确定试验台增速器和变速器的传动比以及试验台变速器的基本参数,设计了钻机试验台的负载加载装置和力测试架。经过对百余台各种类型的钻机进行现场检测,运行结果表明,该大转矩钻机试验台可满足滑履式钻机和履带式钻机各种参数的检测要求。
In order to meet the inspection level of the large torque drilling machine in China coal mine,a testing rig of mine drilling machine with a high torque of 12 000 N·m was researched and developed.The paper introduced the structure and function principle of the testing rig.According to the technical parameters of the drilling machine,the test and measuring parameters of the drilling machine testing rig were determined.With the driving ratio of the speed accumulator and the gearbox in the test ring and the basic parameters of the gearbox in the test rig set up,the loading device and the force measuring frame of the test rig was designed.With the site inspections conducted on over 100 different drilling machines,the results showed that the large test rig could meet the inspection requirements of different parameters for the slide type drilling machine and the crawler drilling machines.
