整体同步移位技术因具有安装精度高、工作效率高、大幅度减少高空作业与支撑用量等优点而广泛应用于大跨空间结构的建造中,但也存在着因不同移动控制方式的设备不兼容、不能通用而带来设备投入量大和利用率低等问题。对目前应用最广的以穿心式千斤顶和预应力钢绞线为承载系统的整体移位系统的移位千斤顶的功能、构造、配置等进行详细分析,提出模块化设计的理念。运用模块化思想进行千斤顶的整体及穿心式千斤顶、撑脚、自动工具锚、顶压器、钢绞线导向装置等组件之间连接方式的设计,成功设计出组合式多功能同步移位系统。工程实践表明该移位系统千斤顶组装拆卸灵活,适应性强,可大大提高设备的周转使用率。
The overall synchronous shift technology is widely used in the construction of long-span space structures due to its advantages of high installation precision, high work efficiency, and greatly reduced the workload of aerial work and support. However, there are also devices that are incompatible due to different mobile control devices , Can not be universal and bring large amount of equipment and low utilization of such issues. At the same time, the function, structure and disposition of the displacement jack, which is the most widely used through-hole jack and prestressing steel strand as bearing system, are analyzed in detail. The concept of modular design is put forward. Using the modular idea to design the jack as a whole and through-core jack, foot support, automatic tool anchors, top pressure device, strand guide and other components of the connection between the design, the successful design of modular multi-function synchronous shift system . Engineering practice shows that the displacement system jack assembly disassembly flexibility, adaptability, can greatly improve the utilization rate of equipment turnover.
