The invention discloses a detector for an overload protection device of a vertical elevator. A grating micrometer device is mounted on a telescopic bracket for mounting the overload protection device in the elevator, and is used for detecting a central position signal of a car platform and transmitting the central position signal to a displacement detector; the displacement detector carries out data processing on the center position signal of the car platform under the set load condition, and the overload center displacement of the car platform is obtained through calculation; and under the no-load condition, a Hall proximity switch moves in the direction close to magnetic steel according to the overload center displacement, whether the overload protection device is qualified or not is judged according to the action condition of the overload protection device, and detection of the overload protection device is achieved. By means of the detector, in the detection process, weights do not need to be carried according to the actual weight of the overload, so that the detection efficiency is greatly improved, the detection result is reliable, and safety guarantee is provided for elevator overload protection detection.

    本发明公开了一种垂直电梯超载保护装置检测仪,在电梯中用于安装超载保护装置的可伸缩支架上安装光栅测微装置,用于检测轿底的中心位置信号,并传送至位移检测仪,由位移检测仪针对设定载荷条件下的轿底的中心位置信号进行数据处理,计算获得轿底的超载中心位移量;空载条件下将霍尔接近开关按超载中心位移量朝向接近磁钢的方向移动,根据超载保护装置的动作状况判断其合格与否,实现对超载保护装置的检测。利用发明实施检测的过程中无需按超载载荷的实际重量搬运砝码,大大提高检测效率,其检测结果可靠,为电梯超载保护的检测提供了安全保障。
