The invention discloses a reduction gearbox counterweight energy-saving system for a quay crane. The reduction gearbox counterweight energy-saving system comprises a hoisting mechanism, a balance reduction gearbox, a balance drum, a counterweight steel wire rope, a movable pulley and a counterweight, and the hoisting mechanism comprises a motor, a hoisting drum and a hoisting reduction gearbox; the motor, the hoisting reduction gearbox and the hoisting drum are connected in sequence; the hoisting drum, the balance reduction gearbox and the balance drum are sequentially connected, one end of the counterweight steel wire rope is wound on the balance drum, the other end of the counterweight steel wire rope bypasses the movable pulley and is fixedly connected with a quay crane structure, the movable pulley is fixedly arranged on the counterweight, and the torque of the counterweight acting on the balance drum is opposite to the torque of a quay crane trolley lifting appliance acting on thehoisting drum. According to the system, electric equipment or operation parameters of the quay crane are not required to be reduced, the operation energy consumption of the quay crane is reduced, thewinding structure of the counterweight steel wire rope is simplified, meanwhile, the length of the hoisting drum is not required to be prolonged, and the service life of the hoisting drum is prevented from being influenced.
本发明公开了一种用于岸桥的减速箱平衡重节能系统,包括起升机构、平衡减速箱、平衡卷筒、平衡重钢丝绳、动滑轮和平衡重,起升机构包括电机、起升卷筒、起升减速箱。电机、起升减速箱和起升卷筒顺次连接。起升卷筒、平衡减速箱和平衡卷筒顺次连接,平衡重钢丝绳的一端缠绕在平衡卷筒上,另一端绕过动滑轮与岸桥结构固定连接,动滑轮固定设于平衡重上,平衡重作用于平衡卷筒上的扭矩与岸桥小车吊具作用于起升卷筒上的扭矩方向相反。本发明无需减少用电设备或降低岸桥的运行参数,降低了岸桥运行的能耗,简化了平衡重钢丝绳的缠绕结构,同时,无需延长起升卷筒的长度,避免影响起升卷筒的使用寿命。
