摘　　要：为了保护电梯轿厢运行安全,行业规定电梯必须安装符合规定标准的上行超速保护装置,在轿厢在超速运行状态下,超速保护装置能够对轿厢运行速度进行控制,保证轿厢运行速度处在缓冲器可承受范围内,避免轿厢发生“冲顶”事故。分析了电梯轿厢上行超速保护装置现状,探究当前轿厢上行超速保护装置的检验标准,并提出几点发展建议。In order to protect the safety of elevator car operation,the industry stipulates that elevators must be equipped with upward overspeed protection devices that meet the prescribed standards.When the car is in overspeed operation,the overspeed protection device can control the speed of the car operation,ensuring that the speed of the car operation is within the range that the buffer can withstand and avoiding accidents such as"roof collision".Based on this,this study analyzes the current situation of elevator car overspeed protection devices,explores the inspection standards for current car overspeed protection devices,and proposes several development suggestions.
