摘要
MQ2000门机经过10年高强度的使用，顶升系统元件老化严重，为保障顶升过程的安全可靠，需进行改造。在分析原系统存在的主要问题的基础上，提出并实施了机械、电气、液压系统的改造方案，通过机电液联调试验和实机拆除试验，证明改造达到了预期效果，提高了设备的性能。
The component of the jacking system for MQ2000 overhead portal crane has been deteriorated severely for the over 10 years intensive employment, so it needs to be repaired in order to ensure its safety and reliability in jacking process. Based on the analysis on the main problems in the former system, this paper puts forward and implements an improved plan in mechanic, electric and hydraulic system. Through the mechanic - electronic - hydraulic debug and real machine disassembly test, it is proved that the improvement has achieved its expected effect, and the equipment performance is enhanced.
