Abstract

The utility model discloses an ultrasonic ranging system for a lift car, and particularly relates to the technical field of lift car safety, the ultrasonic ranging system comprises a controller and a detection device, and the detection device is composed of a clamping screw, a clamping flange, a clamping plate, a clamping disc and various sensors. According to the ultrasonic ranging system for the lift car, the position of the clamping screw is set, under the matching action of the clamping screw, the clamping flange, the clamping plate and the clamping disc, the detection device is fixedly connected with an elevator sill, and then normal work of all sensors is guaranteed. Meanwhile, measured data are transmitted to the controller through the data line, on one hand, normal operation of the elevator is not affected, and on the other hand, whether various parameters meet safety requirements or not can be detected in real time in the elevator operation process.
