The invention discloses an energy-saving overhead crane which comprises a bridge track arranged on an overhead frame, a bridge walking on the bridge track, and a trolley walking on the bridge, wherein the bridge at least comprises a rectangular frame, a lubricating slide way, a side chassis, a side plate and a walking rack; the trolley at least comprises a trolley frame, a trolley motor arranged on the trolley frame and a trolley speed reducer which is arranged on the trolley frame and is in transmission connection with the trolley motor, and transmission split shafts are arranged at the two ends of the trolley speed reducer in the direction from the rail to the frame; sliding assemblies matched with the corresponding lubricating sliding ways are arranged on the left side and the right side of the lower end of the trolley frame respectively, driving assemblies in transmission connection with the transmission split shafts are arranged at the left end and the right end of the trolley frame respectively, and the driving assemblies are in transmission connection with the walking racks. According to the crane disclosed by the utility model, the sliding assembly is matched with the lubricating slideway, so that the running energy consumption is greatly reduced, and the driving assembly does not need to bear the gravity of a trolley and a load, so that the equipment loss is also reduced.
一种节能高架式起重机,包括设置于高架上的桥架轨道、行走于桥架轨道上的桥架、行走于桥架上的小车:所述桥架至少包括矩形框架、润滑滑道、侧置底架、侧置边板、行走齿条;所述小车至少包括小车车架、设在小车车架上的小车电机、设在小车车架上并与小车电机传动连接的小车减速器,所述小车减速器两端沿轨向框架方向设有传动分轴;所述小车车架下端左、右侧分别设有与对应的润滑滑道配合的滑动总成,所述小车车架左、右端分别设有与传动分轴传动连接的驱动总成,所述驱动总成与行走齿条传动连接。本案所述的起重机,其滑动总成与润滑滑道配合大大降低运行的能耗,而所述驱动总成无需承担小车和负载的重力,因此也减少了设备损耗。
