三峡船闸反弧门行程开关增设硬式塑料管探究

Installation of Additional Rigid Plastic Tubes for the Travel Wwitch of the Reverse Arc Gate of Three Gorges Locks

三峡船闸反弧门行程开关是检测反弧门是否运行到位的开关信号,更换反弧门行程开关时,反弧门井下情况复杂,更换人员须系安全绳,在阀门井下拆除旧反弧门行程开关,更换新反弧门行程开关,耗时费力,安全隐患增加。主要从船闸反弧门行程开关的更新改造工艺进行研究,设计出一种硬式塑料管穿装行程开关,通过工艺优化,实现了快速更换,省时省力,降低了工作人员的安全风险,检修效率提高。

Three Gorges locks anti-arc gate travel switch is a switch signal to detect whether the anti-arc gate is running in place,when replacing the anti-arc gate travel switch,the situation under the anti-arc gate well is complicated,the replacement personnel must tie the safety rope,remove the old anti-arc gate travel switch under the valve well,and replace the new anti-arc gate travel switch,the working conditions are complicated,time-consuming and laborious,and the safety hazards increase.Mainly from the ship lock anti-arc door travel switch renewal process research,design a hard plastic tube through the installation of travel switch,through the process optimization,to achieve rapid replacement,save time and effort,reduce the safety risk of staff,maintenance efficiency increased.
