The invention discloses a reduction gearbox balancing weight energy-saving system of a crossing type shore crane. The system comprises an upper trolley energy-saving system and a lower trolley energy-saving system, wherein hoisting mechanisms in the upper trolley energy-saving system and the lower trolley energy-saving system are in transmission connection with energy-saving mechanisms. One end of a lifting steel wire rope is led out from each hoisting mechanism, and the other end of the lifting steel wire rope is connected to a trolley lifting appliance. One end of the balancing weight steel wire rope is led out from an energy-saving mechanism, and the other end of the balancing weight steel wire rope is fixed on the shore crane structure after bypassing the balancing weight movable pulley. The balancing weight movable pulley is fixedly arranged on a balancing weight. Under the condition that the using performance of the shore crane is not reduced, 25% of energy consumption of the shore crane is saved, the balancing weight is controlled through the energy-saving mechanism, the length of a lifting winding drum does not need to be prolonged, and the strength of the lifting winding drum is guaranteed. The balancing weight steel wire rope is easy to wind and does not interfere with other steel wire ropes in operation of the shore crane, the structure is stable, vibration reduction measures are further arranged, and the stability of the shore crane structure is further improved.
本发明公开了一种穿越式岸桥的减速箱平衡重节能系统,包括上小车节能系统和下小车节能系统,上小车节能系统和下小车节能系统中的起升机构与节能机构传动连接。起升钢丝绳的一端由起升机构中引出,起升钢丝绳的另一端连接在小车吊具上。平衡重钢丝绳的一端由节能机构中引出,平衡重钢丝绳的另一端绕过平衡重动滑轮后固定于岸桥结构上。平衡重动滑轮固定设于平衡重上。本发明在不降低岸桥使用性能的情况下节省岸桥25%的能耗,利用节能机构控制平衡重,无需延长起升卷筒的长度,保证了起升卷筒的强度。本发明中平衡重钢丝绳的绕线简单,与岸桥运行中的其他钢丝绳互不干扰,结构稳定,本发明还设置了减振措施,进一步提高岸桥结构的稳定性。
