施工升降机防坠安全器制动距离的测试及分析

Test and analysis of braking distance of anti-falling Brake of personnel hoists

文中对施工升降机防坠安全器制动过程中的加速度进行了测试,并对测试的加速度进行了数据处理,得到了制动速度和制动距离。在对加速度数据处理过程中,探讨了最佳低通滤波频率,辨识了防坠安全器的动作点,提出来零起零落和零轴震荡的数据处理原则,根据此原则对数据进行了零点的调整、数据的截取、趋势的消除,得到了比较满意的结果。

In this paper,the acceleration of the anti falling safety device of the construction elevator in the process of braking is tested,and the data of the acceleration is processed,and the braking speed and the braking distance are obtained.In the process of acceleration data processing,the optimal filtering frequency such as low-pass is discussed,the action points of anti falling safety device are identified,and the data processing principles of zero start and zero drop and zero axis oscillation are put forward.According to this principle,zero adjustment,data interception and trend elimination are carried out for the data,and satisfactory results are obtained.
