为杜绝煤矿井下胶带机胶带打滑摩擦着火事故。近几年来普遍安装使用了低速保护装置,使胶带机在发生胶带打滑吋能可靠自动断电停车。目前多数低速保护均无试验装置,在正常运行中难以掌握保护装置是否灵敏可靠,平时试验也很不方便。为解决这个问题,我们试制成功了一种简便的试验装置,可以在胶带运行过程中随时试验。方法简便,效果良好。 In order to eliminate coal mine belt tape friction and fire accidents. In recent years, the common use of low-speed installation of protection devices, the tape machine in the event of tape slip can automatically and reliably shut down. At present, most of the low speed protection has no test device, and it is difficult to grasp whether the protection device is sensitive and reliable in normal operation or not convenient to test in usual time. To solve this problem, we successfully prototype a simple test device that can be run at any time in the tape test. The method is simple and effective.
