The invention discloses a fine-tuning displacement system for a trolley sling on a crossing-type quay crane. The fine-tuning displacement system comprises a trolley vehicle frame, a moving trolley, moving trolley rails, trolley moving mechanisms, movable trolley wheels and lifting pulley groups, wherein the moving trolley rails are arranged above the trolley vehicle frame; the movable trolley wheels are arranged under the moving trolley; and the movable trolley wheels are arranged on the moving trolley rails in a rolling manner. One end of the each trolley moving mechanism is fixedly connected with the movable trolley, and the other end of the each trolley moving mechanism is fixedly connected with the trolley vehicle frame; and the lifting pulley groups are arranged in a framework of the moving trolley. According to the fine-tuning displacement system for the trolley sling on the crossing-type quay crane disclosed by the invention, the lifting pulley groups are arranged on the movable trolley, movement of the movable trolley is realized by utilizing the trolley moving mechanisms, and a quay crane cart is not needed to be moved in a box aligning process, and the position of the moving trolley only needs to be adjusted, so that an adjustment process is simplified, the operation difficulty is reduced, the working efficiency of the quay crane is improved, the moving frequency of the quay crane cart are reduced, and the energy consumption of the quay crane is reduced.
本发明公开了一种穿越式岸桥上小车吊具微调移位系统,包括上小车车架、移动小车、移动小车轨道、小车移动机构、移动小车车轮和起升滑轮组,移动小车轨道设于上小车车架的上方,移动小车车轮设于移动小车下方,且移动小车车轮滚动设于移动小车轨道上。小车移动机构的一端与移动小车固定连接,小车移动机构的另一端与上小车车架固定连接。起升滑轮组设于移动小车的框架内。本发明将起升滑轮组布置在移动小车上,利用小车移动机构实现移动小车运动,在对箱过程中无需移动岸桥大车,只需调节移动小车的位置,简化了调节过程,降低了操作难度,提高了岸桥的工作效率,同时减少了岸桥大车的移动次数,降低了岸桥的能耗。
