Coupler clamping device and control method thereof

Abstract

The invention relates to the field of trains, and provides a coupler clamping device and a control method thereof. The device comprises a mounting base, a moving shaft, a sleeve, a first clamping jaw,a second clamping jaw and a plurality of pressure monitoring assemblies. The first clamping jaw and the second clamping jaw are oppositely arranged, and a plurality of mounting holes used for mounting the pressure monitoring assemblies are arranged in clamping surfaces of the first clamping jaw and the second clamping jaw; and each pressure monitoring assembly comprises a pressing column, a pressure sensor and a reset piece, the reset piece is arranged between the pressure sensor and the pressing column, a first end of the pressing column extends into the mounting hole, and a second end of the pressing column extends out of the mounting hole. The control method comprises the following steps: judging whether each detection value is smaller than a preset pressure value or not, counting thenumber Y of the detection values smaller than the preset pressure value, and if Y is equal to N, starting an alarm; and judging whether each detection value is equal to zero, counting the number Z ofthe detection values equal to zero, and if Z is greater than zero, starting the alarm. In the invention, multi-point monitoring is realized, and accuracy of a monitoring result is significantly improved.

Description

Technical field [0001] The invention relates to the technical field of trains, in particular to a coupler clamping device and a control method thereof. Background technique [0002] At present, the main engine at the end of the train is connected to the hook device of the train through the coupler. During the operation of the train, the coupler may loosen or even fall off the train, which may cause a safety accident. In order to monitor the fastening degree of the coupler in real time and avoid the above situation, the hook device is generally equipped with a cable displacement sensor and a cable. The cable displacement sensor monitors the change in the length of the cable to determine whether the clamping space of the hook device has increased, and then determine whether the coupler is Loose occurred. Because the cable displacement sensor indirectly judges whether the coupler is loose according to the size of the clamping space, and the cable displacement sensor can only monit...

AI Technical Summary

Problems solved by technology

Since the cable displacement sensor indirectly judges whether the coupler is loose according to the size of the clamping space, and the cable displacement sensor can only monitor one stress point on the hook device, the accuracy of the monitoring results is low, and misjudgment is prone to occur
