Background

At present, as the exploration of resources on land is depleted, the abundant resources on the seabed gradually attract the eyes of all countries in the world. A drilling vessel acquires a large number of cores at each voyage mission. According to statistical data, a decision number is determined as 145 voyages of the ocean drilling plan and the comprehensive ocean drilling plan from 1 month to 9 months in 2013 in 1985, a well is drilled at 2236 mouths, a core is obtained at 279993 meters, and the average core is obtained at about 2000 meters per voyage. With the continuous progress of drilling and coring technology, the heart rate at the flight number station is continuously improved. Wherein the IODP342 voyage drills 9 stations in total, and the total length of the core reaches 5700 meters; the IODP344 underway co-drilled coring at 11 boreholes at 5 different stations for about 1500 meters.

The drillship uses a drill floor and derrick on the ship to drill cores from the seafloor through a core acquisition system. Initially, a long core, typically about 9.5 meters in length, is obtained, first landed on a drill floor and transported by a core conveyor on the drill floor to a core collection area arranged in front of the drill floor, from where it enters the laboratory. In a laboratory, a long core is firstly cut into sections with the length of 1.5 meters, and the whole segmented core is subjected to XCT scanning, physical property detection and half-section. And obtaining a working half-section rock core and a semi-section archival rock core by sectioning, wherein the working half-section rock core is sent into a rock core description and sampling area for experimental activities, and the semi-section archival rock core is sent into a rock core warehouse on a ship for storage after high-definition photographing and ancient geomagnetic detection. After the voyage is finished and the ship is landed, the rock core stored in the rock core storage on the ship is finally transferred to a land rock core storage for storage. Therefore, the operation of transferring and storing a large amount of cores is involved from loading to unloading. However, in most drilling ships, including the 'decision number' and the 'earth number', the core transportation and storage are all dependent on manpower, so that time and labor are wasted, the efficiency is low, the management is difficult, and problems are easy to occur.

Rock core on the current drilling ship shifts and stores in a warehouse and relies on the manpower transport, and the efficiency is low when the crew work load is high, a large amount of rock cores shift, and the management such as classification and serial number of rock core are difficult, and the automatic transportation of rock core and the storage system of a high-efficient intelligence of urgent need development.
