Research and application of intelligent mining spraying robot
Aiming at the problems of low operational efficiency and high labor intensity in traditional manual spraying process in underground coal mine,an intelligent mining spraying robot was developed,and an integrated autonomous spraying operation process based on the roadway spraying process was proposed,which completed the fully automated process of feeding,stirring,long-distance pumping and spraying.The system composition of the intelligent mining spraying robot was introduced,and a robot prototype was developed based on towed power supply,full hydraulic drive,multi-sensor layout and modular design method.The wall perception and path planning technology of the spraying robotic arm were elaborated in detail,achieving more efficient and stable spraying operations for the spraying robotic arm.The practical application showed that one or two workers were required to participate in a spraying operation by intelligent spraying robot,with a work efficiency of 18 minutes per meters;compared with manual operation,the spraying efficiency by the spraying robot was doubled,and the quality of spraying operation was significantly improved,and the efficient and high-quality intelligent spraying operation in underground roadways was achieved.
