双起升岸边集装箱起重机小车的轻型化设计

Lightweight design of trolley of double-lifting quayside container crane

双起升岸边集装箱起重机凭其高工作效率和高可靠的质量在国际上赢得了大量的订单,实用而又新颖的创新理念在行业中享有盛名。但随着岸边集装箱起重机的日益大型化,用户对于轮压、整机尺寸的严格控制,小车沿用以往的设计理念已经不能满足新的市场要求,小车的轻型化设计势在必行。文中介绍了轻型化设计的双起升岸边集装箱起重机小车,对海侧滑轮梁悬臂进行可行性分析,对轨道轮进行了验算,提出了作业工况的实际要求。

Double-lifting quayside container crane is globally ordered in a large quantity thanks to its high working efficiency and reliable quality and enjoys a reputation for its practical and original innovative theory. With gradually upsizing of the quayside container crane and users＇ strict control requirements on the wheel pressure and machine size,former design concept of the trolley cannot meet new market requirement,so lightweight design of the trolley is imperative. The paper introduces the lightweight trolley of the double-lifting quayside container crane,presents feasibility analysis for the cantilever of seaside pulley beam,checks the calculation for the rail pulley,and puts forward actual requirements for the service condition.
