摘　　要：电梯限速器绳张紧装置保障了限速器—安全钳系统的有效动作,也决定了轿厢侧限速器测速的准确性和触发安全钳动作时限速器绳的提拉力。文章从电梯定期检验和安全评估中,列出了几种限速器绳张紧装置失效的案例,分析其产生的原因、存在的危险或潜在隐患,提出整改和安全防范措施,并对检验技术提出相关建议。The tensioning device of the elevator speed limiter rope largely ensures the effective operation of the speed limiter safety gear system,and also determines the accuracy of the speed measurement of the speed limiter car and the lifting force of the speed limiter rope when triggering the safety gear action.The article lists several cases of failure of speed limiter rope tensioning devices from elevator annual inspections and safety evaluations,analyzes their causes,existing dangers or potential hazards,proposes rectification and safety prevention measures,and puts forward relevant suggestions for inspection technology.
