摘要
检验机构在对某新装电梯项目监督检验资料审核时,发现该批次电梯型号的轿门门锁装置电气安全装置上的触点在轿门门锁锁钩脱离挡销时瞬间断开后再次出现持续接通的现象(常闭触点)。通过比较和分析两家型式试验机构检验结论、电梯有关标准及安全技术规范,对该型号轿门门锁装置设计功能实现提出了疑问,重点讨论了质疑之处,并对本次监督检验中发现的问题提出了整改意见。
In the review section of the supervision and inspection data of a newly installed elevator project, inspection institution found a phenomenon that the contact on the electrical safety device of the elevator car door lock device appeared to be continuously turned on after the car door lock lockhook was immediately disconnected(normally closed contact). By comparing and analyzing the type test conclusions of two-type-test institutions, relevant standards and regulations of elevators,this paper raises questions about the realization of design function of car door lock device, focuses on the doubts, and corrected rectification opinions are put forward about the problems of this supervisory inspection.
