Tray anti-falling device of intelligent stereoscopic warehouse

The invention discloses a tray anti-falling device of an intelligent stereoscopic warehouse, and belongs to the field of stereoscopic warehouses, a translation guide rail is fixedly mounted at the bottom end of each group of transverse sliding blocks, a positioning sliding block is mounted on each translation guide rail in a sliding manner, and the stereoscopic warehouses are arranged on the left side and the right side of a traveling mechanism. When the device is used, if a stereoscopic warehouse needs to be expanded, four inserting rods are taken out and inserted into four corresponding butt-joint down-the-holes, iron blocks in the butt-joint down-the-holes and magnets at the ends of the inserting rods are attracted together, and the effect of conveniently expanding the stereoscopic warehouse is achieved; the manufacturing materials of each layer of the stereoscopic warehouse are different, the materials of the fourth layer and above are lighter, and the materials with lower density are selected to manufact
