The invention discloses an anti-swing system for hoisting steel wire ropes of a container crane. The anti-swing system comprises a trolley frame and a hoisting appliance upper frame; a connecting support is arranged at each of the four ends of the upper surface of the hoisting appliance upper frame; each steel wire rope connector is connected with a steel wire rope, and the other end of each steelwire rope is wound on a hoisting winding drum after passing through the corresponding hoisting pulley; when T-shaped frames are horizontal, the two steel wire rope connectors on each T-shaped frame and the two steel wire ropes between the corresponding hoisting pulleys form two waists of an isosceles trapezoid; and a spring damping mechanism is arranged between the bottoms of the two ends of eachT-shaped frame and a movable support. According to the anti-swing system, when the T-shaped frames are horizontal, four congruent isosceles trapezoids with a stable movement function 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 congruent isosceles trapezoids are like four mechanical arms and firmly lock the hoisting appliance upper frame through mutual geometric constraint; and the amplitude of shaking of the hoisting appliance, the hoisting appliance upper frame and the container during container operation can be reduced.
本发明公开了一种集装箱起重机起升钢丝绳防摇系统,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;每个钢丝绳连接头上均连接一条钢丝绳,每根钢丝绳的另一端越过各自的起升滑轮后缠绕在起升卷筒上;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;T型架的两端底部与移动支座之间设置有弹簧阻尼机构。本发明T型架处于水平时在前后左右四个面上形成四个具有稳定运动功能的全等的等腰梯形,在大车或小车行走起制动时,四个全等的等腰梯形像四个机械手臂一样,通过相互间的几何约束,牢牢锁住吊具上架,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。
