The present invention relates to a U-shaped single-rail mobile
laser coal yard inventory device, which includes a U-shaped single rail 1 erected on the steel structure ceiling of the
coal yard. An inventory
instrument trolley for moving along the track
route to conduct
coal yard inventory is inversely arranged on the U-shaped single rail, and an inventory instrument device for actually and specifically scanning the entire coal yard in a full-coverage manner is provided on the inventory
instrument trolley. By adopting a U-shaped single rail and an omnidirectional pan-tilt
laser scanner, during coal yard inventory scanning, by selecting two different
modes of inner-circle scanning and outer-circle scanning, the internal and external sites covered by the U-shaped rail can be scanned in their entirety during one round trip of the trolley. Not only is the
laser coal yard inventory instrument no longer restricted by the coal yard conditions, but also the U-shaped single rail can be laid in sections according to the actual size of the enclosed coal yard and the scanning range, saving track costs, reducing the installation difficulty, and enhancing the versatility of the coal yard inventory device.
