【摘要】：随着长大跨悬索桥在我国的迅猛发展,需要面临如强风沿海地区、山区峡谷等自然条件更加恶劣的施工环境。缆载吊机作为悬索桥加劲梁采用垂直起吊法架设安装的专用起重设备,也必须不断提高自身性能指标以满足吊装难度不断提高的工作环境,所以设计研究一种适应于强台风环境、大吨位吊装、缆上行走能力更强的新型缆载吊机具有重要的实际应用价值。以舟山大陆连岛工程的特大跨海大桥-西堠门大桥钢箱梁架设工程为研究背景,确定了适应于强台风环境下大吨位吊装的新型缆载吊机的主要性能指标和技术参数。总结了国内外现有不同类型的缆载吊机设计方案和工作特点,对整机各主要组成系统和液压控制系统进行方案设计和比选；创新性地设计出了能够使新型缆载吊机实现缆上自行行走的行走系统。对新型缆载吊机在强台风环境下工作的防风抗风措施进行了研究,并设计出了新型抗风装置,最终完成了整机的总体结构设计。选用三维机械设计软件Solid workS建立新型缆载吊机的虚拟样机模型,运用参数化编程语言编程APDL在ANSYS10.0、ANSYS13.0Workbench软件平台上完成主要结构件结构计算；最后完成了整机的工程图设计和样机制造。论文最后介绍并分析了新型缆载吊机风洞试验和结论,完成了整机型式实验方案并分析了静载实验结果,针对缆载吊机在西堠门大桥安装位置的不同设计了不同的整机上缆安装方案。本设计以我国长大跨悬索桥大吨位加劲梁在强台风环境下吊装为设计背景,运用虚拟样机技术、有限元分析技术、边界层风洞实验方法,完成了能够适应于强台风环境、大吨位吊装,缆上自行行走的新型缆载吊机样机研制；对于我国如缆载吊机等悬索桥架设机械的研究和应用有重要借鉴意义。
[Abstract]:With the rapid development of long-span suspension bridges in China, it is necessary to face the construction environment with even worse natural conditions such as strong wind coastal areas and mountain canyons. Cable crane, as a special lifting equipment for suspension bridge stiffening beam erection by vertical lifting method, must also continuously improve its own performance index to meet the increasing difficulty of hoisting work environment. Therefore, the design and research of a new type of cable crane suitable for strong typhoon environment, large tonnage hoisting and stronger walking ability on cable has important practical application value. Based on the construction of steel box girder of Xihoumen Bridge in Zhoushan continental connecting island project, the main performance indexes and technical parameters of a new type cable crane suitable for large tonnage hoisting in strong typhoon environment are determined. The design scheme and working characteristics of different types of cable crane at home and abroad are summarized. The main components and hydraulic control systems of the whole machine are designed and compared. A new type of cable crane is designed to realize self-running on the cable. The wind-proof and wind-resistant measures of the new cable crane working in strong typhoon environment are studied, and a new wind-resistant device is designed. Finally, the overall structure design of the whole machine is completed. The virtual prototype model of the new cable crane is built by using the 3D mechanical design software Solid workS, and the structure calculation of the main structural parts is completed on the ANSYS10.0 ANSYS13.0 Workbench platform by using the parametric programming language (APDL). Finally, the engineering drawing design and prototype manufacture of the whole machine are completed. At last, the paper introduces and analyzes the wind tunnel test and conclusion of the new cable crane, completes the scheme of the whole machine type experiment and analyzes the static load experiment result. According to the different installation position of cable crane in Xihoumen Bridge, different installation schemes are designed. Based on the design background of large tonnage stiffened beam of long-span suspension bridge in China under strong typhoon environment, virtual prototyping technology, finite element analysis technique and boundary layer wind tunnel experiment method are used to complete the design, which can be adapted to strong typhoon environment. The development of a new type of cable crane prototype with large tonnage hoisting and self-running on the cable is of great significance for the research and application of suspension bridge erection machinery such as cable crane in China.
