宁波市电梯下次检验日期计算数据
收藏资源简介：
根据《特种设备安全技术规范TSG T7001-2023 电梯监督检验和定期检验规则》，需对电梯下次检验日期计算方式进行调整，收集宁波市部分电梯作为数据样本，通过电梯参数计算下次检验日期，为使用单位、维保单位提供数据支撑，为检验机构进行检验检测提供依据。1、数据采集：收集电梯数据，包括安装日期、改造日期、大修日期、检验报告编号、检验日期、检验类别等。2、数据处理：（1）检验类别为安装、改造监检: 下次检验日期Yn=检验日期Yj+1年。（2）检验类别为定期检验：①N≤15,Yd(n)≤N＜Yd(n+1)，Yd(n)∈Yd,下次检验日期Yn=电梯基准年份Yz+Yd(n+1)（在用定检）；下次检验日期Yn=电梯基准年份Yz+ Yd(n+1)（重大修理，停用定检）②N＞15,下次检验日期Yn=Yn+1年（在用定检）,下次检验日期Yn=Yj+1年（重大修理，停用定检）。 其中，①安装监检合格日期Ya，收到安装监检报告后更Ya。 ②改造监检合格日期Yg，收到改造监检报告后更新Yg。 ③电梯基准年份Yz= Ya[Yg]。Ya[Yg]表示if Yg：Yz = Yg；else：Yz = Ya。收到安装或改造监检报告后更新Yz。④电梯年限N =当前年份Y-Yz。收到安装或改造监检报告后更新N。⑤定期检验要求年份 Yd ∈【0,1,4,7,9,11,13,15】 ⑥下次检验日期均为月底最后一天。
According to the Special Equipment Safety Technical Specification TSG T7001-2023 Rules for Supervision and Periodic Inspection of Elevators, it is necessary to adjust the calculation method for the next inspection date of elevators. This dataset collects partial elevator samples from Ningbo City, calculates the next inspection date based on elevator parameters, so as to provide data support for elevator users and maintenance units, and provide a basis for inspection institutions to carry out inspection and testing. 1. Data Collection: Collect elevator data including installation date, renovation date, major repair date, inspection report number, inspection date, inspection category, etc. 2. Data Processing: (1) For inspection categories of installation supervision inspection and renovation supervision inspection: The next inspection date Yn = Inspection date Yj + 1 year. (2) For periodic inspection: ① When N ≤ 15, Yd(n) ≤ N < Yd(n+1), Yd(n) ∈ Yd: The next inspection date Yn = Elevator base year Yz + Yd(n+1) (for in-use periodic inspection); The next inspection date Yn = Elevator base year Yz + Yd(n+1) (for major repair, deactivated periodic inspection) ② When N > 15: The next inspection date Yn = Yn + 1 year (for in-use periodic inspection); The next inspection date Yn = Yj + 1 year (for major repair, deactivated periodic inspection) Wherein: ① Installation supervision inspection qualified date Ya: Update Ya after receiving the installation supervision inspection report. ② Renovation supervision inspection qualified date Yg: Update Yg after receiving the renovation supervision inspection report. ③ Elevator base year Yz = Ya[Yg]. Ya[Yg] means: if Yg exists, Yz = Yg; otherwise, Yz = Ya. Update Yz after receiving the installation or renovation supervision inspection report. ④ Elevator service life N = Current year Y - Yz. Update N after receiving the installation or renovation supervision inspection report. ⑤ Required periodic inspection years Yd ∈ [0, 1, 4, 7, 9, 11, 13, 15] ⑥ All next inspection dates shall be the last day of the corresponding month.
