The invention relates to the technical field of elevator safety detection, in particular to an elevator safety tong displacement detection device which comprises a safety tong, at least one lifting rod, a detection piece located on the lifting rod and a detection switch used for detecting the position of the detection piece. And when the safety tongs are in a working state, the lifting rod is pushed and the detection switch is triggered. According to the safety tongs, the lifting rod is connected with the detection piece, when the safety tongs are triggered to generate abnormal displacement under the condition that the load deviation of the elevator car is serious, the safety tongs push the lifting rod to drive the detection piece to move, and the detection switch detects that the detection piece generates abnormal displacement, a fault signal can be continuously sent out; the elevator safety tongs fault condition can be quickly judged by a maintainer, the fault reason of the elevator safety tongs can be checked without manually entering an elevator shaft, the elevator overhaul and maintenance efficiency is improved, and the carrying efficiency of a cargo elevator is improved.

    本发明涉及电梯安全检测技术领域,具体是一种电梯安全钳位移的检测装置,包括安全钳、至少一个提拉杆、位于所述提拉杆上的检测件和用于检测所述检测件位置的检测开关,所述提拉杆的一端连接所述安全钳,所述安全钳处于工作状态时推动所述提拉杆并触发所述检测开关。本发明的安全钳通过提拉杆与检测件连接,当电梯轿厢的载重偏移比较严重的情况下,导致触发安全钳产生异常位移时,安全钳推动提拉杆带动检测件移动,检测开关检测到检测件出现异常位移时,会持续发出故障信号,有助于检修人员快速判断电梯安全钳故障情况,无需人工进入电梯井道也可以排查电梯安全钳故障原因,提高电梯的检修维护效率,提高货物电梯的搬运效率。
