大吨位真空吸管器抽真空系统及吸盘的研制应用

Development and Application of Vacuum System and Vacuum Chuck for Large Tonnage Vacuum Pipe Lifter

抽真空系统和吸盘是管道施工真空吸管器的关键部件,对真空吸管器实现管道吊装、布管作业、保障安全起到重要作用。本文简要介绍了真空吸管器的原理、结构和使用特点,根据管道施工吊装作业工况,分析确定了相关设计要求和技术参数,对抽真空系统动力配置、传动和吸盘进行设计,解决了抽真空系统在失去动力后仍可维持吸盘工作的安全性问题。经技术检测和工程现场应用,达到了真空吸管器设计要求。

The vacuum system and vacuum chuck are the key components for the vacuum pipe lifter in the pipeline construction,which play an important role in the pipeline construction hoisting,pipe laying and safety assurance.This paper briefly introduces the structure principle of the vacuum pipe lifter and usage characteristics,analyzes and determines the relevant design requirements and technical parameters of the vacuum pipe lifter according to the pipeline construction hoisting requirements and working conditions.The design of force configuration,transmission and vacuum chuck solves the safety problem that the vacuum chuck can still be maintained after the vacuum system loses power.After technical inspection and application,it meets the design requirements of vacuum pipe lifter.
