The invention discloses a hoist rope stable motion system for a gantry crane. The hoist rope stable motion system involves a trolley frame and a lifting appliance upper frame; the four ends of the upper surface of the lifting appliance upper frame are each provided with a connecting support, and each connecting support comprises a movable support and a T-shaped frame; an anti-swing mechanism for controlling the swing amplitude of the T-shaped frame is arranged on each movable support; each steel wire rope connector is connected with a steel wire rope; when the T-shaped frames are horizontal, the two steel wire rope connectors on each T-shaped frame and the two steel wire ropes between corresponding lifting pulleys form two legs of an isosceles trapezoid; and the four isosceles trapezoids where the steel wire ropes on the four T-shaped frames are located are kept congruent when the T-shaped frames are in the horizontal state. According to the system, four basically congruent isosceles trapezoids with stable movement functions are formed on the front face, the rear face, the left face and the right face, and when a cart or a trolley travels and brakes, the four basically congruent isosceles trapezoids are like four mechanical arms, so that the amplitude of shaking of a lifting appliance, the lifting appliance upper frame and a container during container operation can be reduced.

    本发明公开了一种场桥用起升钢丝绳稳定运动系统,包括小车架、吊具上架;吊具上架上表面的四端各设置有一个连接支座,连接支座包括移动支座、T型架;每个移动支座上均设置有一个控制T型架摆动幅度的防摆机构;每个钢丝绳连接头上均连接有一条钢丝绳;T型架处于水平时,每个T型架上两个钢丝绳连接头与各自相应起升滑轮之间的两根钢丝绳形成等腰梯形的两条腰;四个T型架上钢丝绳所处于的四个等腰梯形在T型架处于水平状态时保持全等。本发明在前后左右四个面上形成四个具有稳定运动功能的基本全等的等腰梯形,在大车或小车行走起制动时,四个基本全等的等腰梯形像四个机械手臂一样,可以减小集装箱作业时吊具、吊具上架和集装箱晃动的幅度。
