摘　　要：为给采面综采设备自动调直提供基础并实现刮板输送机直线度检测,提出了融合惯导、里程计以及激光雷达的刮板输送机直线度检测技术。通过里程计、惯导信息融合可获取刮板输送机在采面倾向范围内的直线度,同时在采煤机割煤前通过激光雷达确定刮板输送机机头、机尾两端坐标信息,便于解决里程计、惯导长时间、长距离运行后累计误差偏大问题。将所提技术方法在3506综采工作面进行工程试验,结果表明:布置的刮板输送机机头、机尾位置的激光雷达检测误差在0.05 m以内;直线度检测技术在采面倾向150 m范围内刮板输送机直线度偏差在0.07 m以内,可为采面液压支架后续自动调直提供较好基础。In order to provide the basis for the automatie straightening of comprehensive mining equipment in the mining face and realise the straightness detection of scraper conveyor,the straightness detection technology of scraper conveyor integrating inertial guidance,odometer and LiDAR is proposed.The straightness of the scraper conveyor in the tendency range of the mining face can be obtained through the fusion of odometry and inertial guidance,and the coordinates of the head and tail ends of the scraper conveyor can be determined by LIDAR before the coal mining machine cuts the coal,which is convenient for solving the problem of the accumulative error after the odometry and the inertial guidance have operated for a long time and over a long distance.The proposed technology and method are tested in 3506 comprehensive mining face,and the results show that:the LIDAR detection error of the position of the head and tail of the scraper conveyor is within 0.05 m;and the straightness detection technology has the straightness deviation of the scraper conveyor within 0.07 m in the range of 150 m of the tendency of the mining face,which provides a better basis for the subsequent automatic straightening of the hydraulic support at the mining face.
