摘　　要：在直立式岸电设施的接电箱升降过程中,如供电电缆承受额外载荷,岸电设施安全性将受到显著影响。针对以上问题,结合三峡库区旧州河锚地大水位差下岸电设施实际工程需求,设计了1套由接电箱平台和提升机构组成的接电箱升降装置:接电箱平台主体采用桁架结构,可沿垂直轨道上下运行;提升机构由提升绞车和动滑轮组组成,用以驱动接电箱平台。利用三维BIM软件Inventor对接电箱平台主体结构进行三维建模和力学分析,通过空间三维力学分析推导所需提升绞车牵引力。结果表明:设计的电箱平台主体结构能够满足强度要求,提升绞车牵引力能够满足提升要求。The security of the upright shore-to-ship power supply system will be significantly affected when its cable is pulled up by extra load.To solve this problem,combined with the actual engineering needs of shore-to-ship power supply system under the large water level difference of the Jiuzhou River anchorage in the Three Gorges reservoir area,a connection box lifting device is designed which consists of electric box platform and lifting mechanism.The electric box platform can run up and down the track,and its main structure is truss structure.The lifting mechanism consists of hoisting gear and pulley block which is used to drive the electric box platform.And then,the truss structure is modeled and analyzed using the 3D BIM software Inventor,and the traction of hoisting gear is calculated.The results show that the truss structure can meet to requirements of the strength,the traction can meet the requirements of the hoisting.
