The invention discloses an energy-saving tower crane capable of assisting in conducting rotation through wind energy. The energy-saving tower crane comprises a tower crane body, a balance arm is fixedly installed at the top end of one side of the tower crane body, a cargo boom is fixedly installed at the top end of the other side of the tower crane body, and closing assemblies are installed on the surfaces of the balance arm and the cargo boom at equal intervals. The closing assemblies are installed on the surfaces of the balance arm and the cargo boom at equal intervals, in the downwind process, shutter leaves on the cargo boom are closed, the wind shielding area of the cargo boom is increased, shutter leaves on the balance arm are opened, the wind shielding area of the balance arm is reduced, the wind pressure borne by the cargo boom is larger than that borne by the balance arm, and windward rotation of the cargo boom is achieved. In the upwind process, the shutter leaves on the cargo boom are opened to reduce the wind shielding area of the cargo boom, the shutter leaves on the balance arm are closed to increase the wind shielding area of the balance arm, and therefore the wind pressure borne by the balance arm is greater than that borne by the cargo boom, the cargo boom can rotate against wind, the energy consumed when the tower crane rotates is reduced, and the energy consumption of a rotary motor is reduced.
本发明公开了一种可利用风能辅助回转的节能塔机,包括塔机本体,所述塔机本体一侧的顶端固定安装有平衡臂,所述塔机本体另一侧的顶端固定安装有起重臂,所述平衡臂与起重臂的表面等距安装有闭合组件。本发明通过在平衡臂与起重臂的表面等距安装的闭合组件,顺风时,起重臂上的百叶闭合,增加起重臂的挡风面积,平衡臂上的百叶打开,减小平衡臂上的挡风面积,使起重臂上所受到风的压力大于平衡臂,实现起重臂迎风转动,逆风时,起重臂上的百叶打开,减小起重臂的挡风面积,平衡臂上的百叶闭合,增加平衡臂上的挡风面积,使平衡臂上所受到风的压力大于起重臂,实现起重臂逆风转动,降低塔机回转时消耗的能量,降低了回转电机能耗。
