我矿主斜井采用2JK2×1A-20型卷扬机,它的机械制动系统是液压传动装置,机械制动闸的调节是通过制动手柄传动自整角机以控制液压调节阀来实现的。当自整角机或液压调节阀发生故障时,就会引起液压失控,机械闸失效,以致使提升容器跑车,甚至造成重大人身设备事故,我矿就先后多次发生这样事故。为了解决这一问题,我们研制成功了卷扬机液压调节系统的故障保护器。 实践表明:开车前的起始液压在1.5公斤左右易于操作,若起始液压超过3公斤,当发生故障(即自整角机输出电压不为零,而使液压调节阀已经稍有打开)而又解除电
Mine mine inclined shaft using 2JK2 × 1A-20-type winch, and its mechanical brake system is a hydraulic transmission, the mechanical brake is adjusted by the brake handle drive synchro machine to control the hydraulic control valve to achieve. When the synchro or hydraulic control valve fails, it will cause hydraulic runaway, mechanical brake failure, so that to enhance the container sports car, and even cause major personal equipment accidents, mine mine has repeatedly such an accident. In order to solve this problem, we have successfully developed the fault protector for the winch hydraulic adjustment system. Practice shows that: the starting hydraulic pressure before driving is about 1.5 kg, easy to operate. If the initial hydraulic pressure exceeds 3 kg, when the fault occurs (that is, the output voltage of the autotrake is not zero and the hydraulic control valve is slightly opened) And lift the electricity
