Exploration of Ultrasonic Wave for Coal Surface Detection of Train Gantry Sampler
The coal surface position of the fire coal loaded in the train carriage is a benchmark for the sampling depth of gantry sampler.The previous coal surface detection device is mechanical haulage type,and the structure is relatively complex.Due to the large vibration of the sampling machine during sampling,the coal surface detection device has frequent problems,which reduces the performance of the equipment and increases the maintenance cost.Based on this condition,in combination with the actual situation,ultrasonic sensor is used in this paper for the detection of coal surface.Through site application effect tracking,the ultrasonic sensor is observed to have stable operations and not being disturbed by dust and vibration,and the effect is good,so as to solve this problem.
