摘　　要：针对我国换热器抽芯设备的落后状况 ,提出了新型换热器高空抽芯作业车的设计方案。论述了这种作业车的基本结构、工作原理和技术指标。运用结构力学的矩阵分析法和计算机对抽芯作业车主体金属结构做了力学分析与计算 ,进而校核主体金属结构的强度、刚度和稳定性。设计将作业车的起重、抽芯和行走三大功能集于一体 ,控制系统采用电液联合控制 ,工作台能自动升降 ,自动抽芯 ,抽芯速度快 ,改变了以往依赖吊车配合作业的落后局面。这种作业车的研制对提高我国石油及石化行业设备检修效率 ,缩短检修时间 。The design scheme for a new aerial cone-extracting truck for heat exchangers is put forward. The structure, operating principle and technical index of the truck are expounded. Mechanical analysis and calculation of the truck's metal construction are made by the matrix method, and the strength, rigidity and stability of the metal construction are checked. The truck adopts electric and hydraulic combined control, and it operates full automatically with high core-extracting speed.
