Direct-drive lifting mechanism of mining excavator and excavator
The invention discloses a direct-drive lifting mechanism of a mining excavator and the excavator. The direct-drive lifting mechanism comprises a lifting winding drum, a first motor, a second motor and a workbench. The lifting winding drum comprises a first winding drum, a second winding drum and a brake disc, and the first winding drum and the second winding drum are arranged on the two sides of the brake disc respectively, positioned with the brake disc through spigots and connected with the brake disc through super bolts; the first motor is connected with the end of the first winding drum, and the second motor is connected with the end of the second winding drum and used for driving the first winding drum and the second winding drum to rotate synchronously. The bottoms of the first motor and the second motor are connected to the workbench, and the first motor and the second motor are permanent magnet motors. The lifting winding drum is of a split structure of spigot positioning and super bolt fixing, the structure is simple, machining is convenient, and meanwhile the positioning precision is high. The permanent magnet motor is adopted to directly drive the winding drum, so that the efficiency is improved by 15%-20%, the energy consumption and the heat dissipating capacity are greatly reduced, the indoor temperature is improved, the burden of a ventilation system is reduced, the failure rate is reduced, and the equipment mobility is improved.
本发明公开了一种矿用挖掘机直驱提升机构及挖掘机，该直驱提升机构包括：提升卷筒、第一电机、第二电机和工作台；提升卷筒包括第一卷筒、第二卷筒和制动盘，第一卷筒和第二卷筒分别设置于制动盘的两侧，与制动盘之间通过止口定位并通过超级螺栓连接；第一电机与第一卷筒的端部连接，第二电机与第二卷筒的端部连接，用于带动第一卷筒和第二卷筒同步转动；第一电机和第二电机的底部连接在工作台上，第一电机和第二电机为永磁电机。提升卷筒采用止口定位，超级螺栓固定的分体式结构，结构简单，加工方便，同时定位精度高。采用永磁电机直接驱动卷筒提高效率15％～20％，大幅降低能耗和散热量、改善室内温度、降低通风系统负担、低降故障率提升设备可动率。
