北洺河铁矿使用的TORO 400E电动铲运机由芬兰生产,其卷缆装置主要由卧式电缆卷盘与导向臂2部分组成,液压马达通过弹性联轴器带动卧式卷缆盘旋转进行卷缆。放缆时依靠铲运机运行时电缆的张力带动卷缆盘和液压马达反转,使马达处于泵的工况,卷缆液压系统控制液压马达的回油压力,以保持电缆适当的张力,不至于松卷而出现轧电缆的事故。
The TORO 400E electric scraper used at Beibeihe Iron Mine is made in Finland. The cable winding device mainly consists of two parts: a horizontal cable reel and a guide arm. The hydraulic motor drives the horizontal cable reel to rotate through an elastic coupling Cable. The cable tension depends on the tension of the cable driven by the scraper during cable deployment to reverse the cable drum and the hydraulic motor so that the motor is in the condition of the pump and the cable hydraulic system controls the return pressure of the hydraulic motor to maintain the proper tension of the cable As for the volume of rolled cable accident occurred.
