The invention provides a steel rope drum for a double-beam hook portal crane, and belongs to the technical field of crane parts. The steel rope drum comprises a drum and bearing seats, safety rings are arranged at a left end and a right end of the drum, an inner shaft tube is nested in the middle section in the drum, a first outer end shaft tube is nested on the left side in the drum, and a secondouter end shaft is nested on the right side in the drum; and two ends of the drum are fixedly connected with drum hubs through bolts. Steel ropes can be adjusted to wind different drum surfaces so asto adapt to different operation demands, and the diversity of the use can be increased; twisting forces on the drum can be conducted by three sections of shaft tubes in the drum through three sections, so that the twisting stress of the whole drum is uniform, the service life of the shaft tube is improved, shaft tubes at the two ends of the drum are replaced; and after the use consumption of thedrum of the crane, the whole drum can be prevented from being replaced by replacing the shaft tubes at the two ends of the drum.

    本发明提供了一种双梁吊钩门式起重机用钢绳卷筒,属于起重机零部件技术领域,包括卷筒、轴承座,卷筒的左右两端设置有安全圈,卷筒的内部中段嵌套设置有内轴管,卷筒的内部左侧嵌套设置有第一外端轴管,卷筒的内部右侧嵌套设置有第二外端轴管,卷筒的两端通过螺栓固定连接有卷筒毂,本发明可以调节钢绳缠绕不同的卷筒面,适合不同的作业需求,可以增加使用的多样性,卷筒内三段轴管可以将卷筒上的扭转力经过三段传导,使整个卷筒的扭转受力均匀,提高轴管的使用寿命,对卷筒两端的轴管进行更换,在起重机的卷筒使用消耗后,通过对卷筒两端的轴管进行更换,避免整体更换卷筒。
