CARGO STORAGE SYSTEM

摘要

Disclosed is a cargo storage system which comprises a cargo temporarily-depositing device and a stacker. The stacker includes a machine frame (210) and a cargo carrying platform (220). Three sensors (211; 212; 213) are arranged on the machine frame (210). The cargo temporarily-depositing device includes a lifting platform (230) and a roller platform (240), with the middle part of the lifting platform (230) forming a hollow structure. The cargo carrying platform (220), the lifting platform (230) and the roller platform (240) are respectively lifted vertically between a high position and a low position. On the temporarily-depositing device, a first reflecting plate (251) is arranged at a position corresponding to the high position of the roller platform (240), and a second reflecting plate (252) is arranged at a position corresponding to the high position of the lifting platform (230) with a third reflecting plate (253) fastened thereon. The three sensors (211; 212; 213) respectively sense the three reflecting plates (251; 252; 253) for notifying whether to stop the stacker according to sensing results. Crashing between stackers in the cargo storage system caused by burst potential safety hazard can be avoided by this way.
