The invention provides a quay crane lifting trolley steel wire rope torsion resistance structure, and relates to the technical field of steel wire rope torsion resistance, the quay crane lifting trolley steel wire rope torsion resistance structure comprises a winding drum, a steel wire rope starts from the winding drum, passes through a lifting pulley block after bypassing a tensioning pulley, then passes through a redirection pulley block and then passes through the lifting pulley block again, and then starts from the lifting pulley block; and finally, the steel wire rope returns to the winding drum, an automatic push rod is installed on the lifting trolley body, and the telescopic end of the automatic push rod is connected to a displacement mechanism of the lifting pulley block. The structure has the beneficial effects that the structure is connected to a lifting pulley block, so that the stroke from a steel wire rope to a lifting appliance is shortened, the rotation angle adjusting precision of the lifting appliance is improved, two working modes of single and double lifting appliances can be simultaneously realized under a single lifting system, an operator does not need to manually recover the twisting of the lifting appliance, and the working efficiency is improved. The lifting appliance can rapidly rotate and rapidly reach the box aligning position, manpower is saved, the box aligning efficiency is improved, and therefore the loading and unloading efficiency of a quay crane is improved.

    本发明提出了一种岸桥起升小车钢丝绳抗扭结构,涉及钢丝绳抗扭技术领域,包括卷筒,钢丝绳从卷筒出发,绕过张紧滑轮后经过起升滑轮组,随后通过改向滑轮组后再次经过起升滑轮组,然后从起升滑轮组出发,绕过吊具滑轮组后再次经过张紧滑轮组,最后钢丝绳回到卷筒,起升小车主体上安装有自动推杆,自动推杆的伸缩端连接在起升滑轮组的变位机构上。该结构的有益效果是:该结构连接于起升滑轮组上,缩短了钢丝绳距吊具的行程,对吊具的回转角度调节精度加大,能在单起升系统下同时实现单、双吊具两种作业模式,无需操作人员手动恢复吊具扭动,能够使吊具快速回转并迅速达到对箱位置,节约人力且提高对箱效率,从而提高岸桥的装卸效率。
