针对高速电梯的补偿钢丝绳在电梯正常工作时存在一定的抖动和在紧急工况能够产生巨大的冲击力等特点,设计了一套液压系统控制的补偿钢丝绳张紧装置。利用AMESim仿真分析了两种工况下的系统响应,结果表明采用该液压系统控制的张紧装置,在发生紧急工况时可以快速输出足够的力来阻止钢丝绳的上跳,以保证电梯的安全;在正常运行时液压系统的阻尼作用也有效降低了钢丝绳的晃动,提高了电梯的平稳性。
The compensation wire rope for high-speed elevator has some characteristics of jitter in normal elevator operation and huge impact force in emergency conditions. A set of compensation wire rope tensioner controlled by hydraulic system is designed. The system response under two operating conditions was analyzed by AMESim simulation. The results show that the tensioning device controlled by the hydraulic system can quickly output enough force to stop the wire rope from jumping in the emergency condition to ensure the safety of the elevator During normal operation, the damping effect of the hydraulic system effectively reduces the sway of the rope and improves the stability of the elevator.
