摘　　要：研制了一种新型JC70DB型绞车,该绞车采用2台860kW交流变频电机驱动,通过1台两挡齿轮减速箱驱动滚筒,在滚筒轴另一侧安装有液压盘式刹车和电磁涡流刹车。绞车刹车采用主电机能耗制动、液压盘式刹车和电磁涡流刹车共同作用。电磁涡流刹车刹车力矩通过PLC程序控制,由控制系统根据动力模型自动投入。液压盘式刹车采用全常闭钳结构,控制方式为电控液,液压站安装在绞车上。A new efficient JC70 DB drawworks is driven by two 860 kW AC frequency motor.One2-shifts gearbox drives drum.The hydraulic disc brake and the electromagnetic eddy current brake is installed on the other side of drum.The brake system uses dynamic braking system,the hydraulic disc brake system and the electromagnetic eddy current brake system which is controlled by PLC.The moment of the electromagnetic eddy current brake system is controlled by the PLC program,which is based on dynamic model.The hydraulic disc brake system uses safety caliper structure,the valves of which are controlled by electrical signal.The hydraulic station is installed on the foundation of drawworks.
