The invention relates to the technical field of elevator speed governor safety tongs linkage test detection, in particular to an elevator speed governor safety tongs linkage test detection method and system. The elevator speed governor safety tongs linkage test detection method comprises the following steps that S1, an elevator speed governor safety tongs linkage test is executed, and if the action of safety tongs fails, the lifting force of a steel wire rope arranged on an elevator speed governor and the safety tongs in the slipping state is collected; and S2, whether the collected lifting force of the steel wire rope is within a preset threshold range or not is judged, if yes, a detection result is that the safety tongs are abnormal, and if not, the detection result is that the speed governor is abnormal. The measured lifting force of the steel wire rope is compared with a preset threshold value, so that the working state of the safety tongs of the speed governor can be quickly judged, and the main reason for action failure of the safety tongs in the linkage test of the speed governor and the safety tongs is found out.

    本发明涉及电梯限速器安全钳联动试验检测技术领域,尤其涉及一种电梯限速器安全钳联动试验检测方法和系统,包括以下步骤:S1:执行电梯限速器安全钳联动试验,若所述安全钳动作失效,则采集置于电梯限速器以及安全钳上的钢丝绳在打滑状态下的提拉力;S2:判断采集到的钢丝绳的提拉力是否在预设阈值范围内;若是,则得出检测结果为安全钳异常;若否,则得出检测结果为限速器异常。通过测量所得的钢丝绳的提拉力与预设阈值进行比较能够快速判断限速器安全钳的工作状态,找出在限速器安全钳联动试验中安全钳动作失效的主要原因。
