The invention discloses a bridge crane cable drum power supply device which comprises a cable drum, a fixed pulley block, a ground power supply cabinet and an onboard power supply cabinet, the cable drum, the fixed pulley block and the onboard power supply cabinet are fixedly installed on a bridge crane, and a cable of the ground power supply cabinet is connected to a cable bridge. A cable side pull net sleeve is arranged on the cable bridge, the cable side pull net sleeve is connected with a fixed pull ring, the cable penetrates through the cable side pull net sleeve and then is connected with the cable drum through a fixed pulley block, and the electric energy output end of the cable drum is connected with the input end of the onboard power supply cabinet. The cable drum is adopted as power supply equipment of the bridge type grab crane and is matched with the pulley block and the cable bridge, so that sparks, pulverized coal deflagration and safety accidents can be prevented from being generated in the operation process, meanwhile, the cable is fixed in the mode that the side pulling net sleeve is matched with the fixing pull ring, and the operation safety and reliability are further improved.

    本发明公开了一种桥式起重机电缆卷筒供电装置,包括电缆卷筒、定滑轮组、地面电源柜和机上电源柜,所述电缆卷筒、定滑轮组和机上电源柜固定安装于所述桥式起重机上,所述地面电源柜的电缆连接至一电缆桥架上,所述电缆桥架上设置有电缆侧拉网套,所述电缆侧拉网套与一固定拉环连接,所述电缆穿过所述电缆侧拉网套后再通过定滑轮组连接所述电缆卷筒,所述电缆卷筒的电能输出端与所述机上电源柜输入端连接。本发明通过采用电缆卷筒做为桥式抓斗起重机的供电设备,配合滑轮组、电缆桥架,能够防止运行过程中产生火花,引发煤粉爆燃,造成安全事故,同时采用侧拉网套配合固定拉环的方式固定电缆,进一步提高运行安全可靠性。
