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 testing level of the large torque coal mine in our country, a test rig of 12 000 N · m for large torque coal mine was developed. The structure and function principle of the test rig are introduced. According to the technical parameters of the rig, the rig test rig Test parameters, and by determining the test bed transmission and transmission gear ratio and the basic parameters of the test rig transmission, the design of the rig load test rig loading and force test stand. After the test of more than 100 sets of various types of rigs on site, the operation results show that the large torque rig test bench can meet the testing requirements of various parameters of the crawler rigs and crawler rigs.
