A dynamic parameter measuring instrument for an elevator brake relates to the technical field of special equipment elevator inspection and is used for measuring trigger time in a brake test process, speed of a traction wheel and a steel wire rope during triggering, maximum speed/distance/deceleration in a brake process and brake response time. In the dynamic parameter measuring instrument for the elevator brake, a rotary encoder tachometer wheel of a measuring device is fixed with a magnetic attraction base through a bracket, and is in contact with an elevator traction wheel and a steel wire rope between the traction wheel and a guide wheel; a Hall sensor of the power-off monitoring device is used for collecting a current signal in a brake circuit or a safety loop at an elevator control cabinet; during a brake test, when a Hall sensor acquires a current signal in a brake circuit or a safety loop at an elevator control cabinet, the current signal is suddenly changed into 0, the current signal is a timing starting point of the brake test, and important time data is provided for data analysis and processing of subsequent brake parameters; and the measurement host communicates with the operation terminal through wireless communication.
一种电梯制动器动态参数测量仪,涉及特种设备电梯检验技术领域,其用于测量制动器试验过程中的触发时间、触发时曳引轮及钢丝绳的速度、制动过程中的最大速度/距离/减速度、以及制动响应时间。所述电梯制动器动态参数测量仪中,测量装置的旋转编码器测速轮通过支架与磁吸底座固定,并与电梯曳引轮、以及曳引轮和导向轮之间的钢丝绳接触;断电监测装置的霍尔传感器用于采集电梯控制柜处制动电路或安全回路中的电流信号;在制动试验时,当霍尔传感器采集到电梯控制柜处制动电路或安全回路中的电流信号突变为0时,此时为制动试验的计时起点,并为后续制动参数的数据分析和处理提供重要的时间数据;测量主机通过无线通信与操作终端进行通信。
