输电线路大型铁塔组立专用塔式起重机的设计与优化

Design and Optimization of Special-Purpose Tower Crane for Large Tower of Transmission Line

针对输电线路工程铁塔塔材重、塔身高、就位难度大、安装精度要求严、施工环境复杂、安全风险大的特点,综合考虑重量、可操控性、施工效率、场地占用等因素,开展专业化设计,研制成功输电线路组塔大型专用塔式起重机,采用单动臂上回转结构、装配式基础、平衡重系统、分片式标准节、下顶升机构、自拆卸施工等先进的技术方案,具有施工效率高、安全性好、场地和人员占用少等优点,满足了特高压工程铁塔的组立施工需要,已在特高压电网施工中得到广泛应用。

Transmission line tower has the features of tower material weight, tower height high, difficulty in installation, high accuracy, complicated installation, complex construction environment and grave risk. Comprehensive consideration of weight, maneuverability, construction efficiency, site occu-pancy and other factors, to carry out professional design, the large special tower crane used for the large tower of transmission line is successfully developed. The special tower crane adopts the advanced technological scheme such as single jib, the top rotary structure, the assembling founda-tion, the balanced weight system, the chip standard section, the under jacking mechanism and the self-removal function. The special tower crane has the advantages of high efficiency, good safety, small space and personnel, etc. The special tower crane meets the need of the construction of the special high pressure engineering tower, and has been widely used in the construction of UHV power network.
