The invention discloses a lifting appliance swing preventing system for a crossing type double-trolley quay crane. The system comprises an upper trolley lifting appliance swing preventing device and a lower trolley lifting appliance swing preventing device. Each of the upper trolley lifting appliance swing preventing device and the lower trolley swing preventing device comprises a bottom frame, a torque motor, a swing preventing winding drum and a swing preventing steel wire rope, wherein each torque motor and the corresponding swing preventing winding drum are in transmission connection, each torque motor and the corresponding swing preventing winding drum are fixedly arranged on the corresponding bottom frame, one end of each swing preventing steel wire rope is wound around the corresponding swing preventing winding drum, and the other end of each swing preventing steel wire rope is fixedly connected with a corresponding lifting appliance. According to the lifting appliance swing preventing system, stable operation of an upper trolley and a lower trolley in the crossing type quay crane can be guaranteed, the shake and the swing of the upper trolley lifting appliance and the lower trolley lifting appliance are effectively reduced, operation of the upper trolley and the lower trolley cannot be affected, and the mutual interference of the upper trolley and the lower trolley is avoided. The swing preventing steel wire ropes in the system do not bear the tension in the normal using process and can effectively operate for a long time, and the lifting appliance swing preventing system is simple in arrangement, stable in operation and low in initial investment and operation maintenance cost.

    本发明公开了一种用于穿越式双小车岸桥的吊具防摇系统,包括上小车吊具防摇装置和下小车吊具防摇装置,上小车吊具防摇装置和下小车防摇装置均包括底架、力矩马达、防摇卷筒和防摇钢丝绳,力矩马达和防摇卷筒传动连接,且力矩马达和防摇卷筒均固定设于底架上,防摇钢丝绳的一端缠绕于防摇卷筒上,另一端与吊具固定连接。本发明能够保证穿越式岸桥中上小车和下小车稳定运行,有效地减弱了上小车吊具和下小车吊具的晃动摇摆,并且不会影响上小车和下小车的运行,防止上小车和下小车互相干扰。本发明中的防摇钢丝绳在正常使用中不承受拉力,能够长期有效运行,且本发明布置简单,运行稳定,初始投资和运行维护成本低。
