The invention discloses a counterweight energy-saving system for a through-type quay crane. The system is characterized in that each of an upper trolley energy-saving system and a first lower trolley energy-saving system comprises a motor, a reduction gearbox, a hoisting drum, a counterweight steel wire rope, a counterweight pulley block, a counterweight and a hoist rope, wherein the motor, the reduction gearbox and the hoisting drum are in transmission connection in sequence; and one end of the hoist rope is wound on the hoisting drum while the other end of the hoist rope is connected to an upper trolley lifting appliance or a lower trolley lifting appliance. One end of the counterweight steel wire rope is wound on the hoisting drum while the other end of the counterweight steel wire rope bypasses the counterweight pulley block and is fixed on a quay crane structure, the direction of the torque of the counterweight steel wire rope to the hoisting drum is opposite to that of the torque of the hoist rope to the hoisting drum, and the counterweight pulley block is connected to a counterweight. According to the system, 25% of energy consumption of the quay crane can be saved, winding is simple and does not interfere with other steel wire ropes on the trolley lifting appliances, and meanwhile, the flat hoist rope and the counterweight steel wire rope do not interfere with each other, so that the strength of the hoisting drum is ensured.

    本发明公开了一种用于穿越式岸桥的平衡重节能系统,上小车节能系统和第一下小车节能系统均包括电动机、减速箱、起升卷筒、平衡重钢丝绳、平衡重滑轮组、平衡重和起升钢丝绳,电动机、减速箱和起升卷筒顺次传动连接,起升钢丝绳的一端缠绕于起升卷筒上,另一端与上小车吊具或下小车吊具连接。平衡重钢丝绳的一端缠绕于起升卷筒上,另一端绕过平衡重滑轮组固定于岸桥结构上,且平衡重钢丝绳对起升卷筒的扭矩与起升钢丝绳对起升卷筒的扭矩方向相反,平衡重滑轮组与平衡重连接。本发明能够节省岸桥25%的能耗,绕线简单,与小车吊具上的其他钢丝绳互不干扰,同时本发明中的平起升钢丝绳和平衡重钢丝绳互不干扰,保证了起升卷筒的强度。
