[0030] Workflow:

[0031] First, when the shelf is in the inventory state and the goods on a certain moving frame 6 need to be taken, the two pairs of half thread grooves 11 on the two pairs of protrusions 10 on the moving frame 6 are combined into two complete thread grooves, the two thread grooves are threadedly connected with the first screw rod 3 and the second screw rod 4, the first bolts 13 on the two pairs of protrusions 10 are tightened, the four locking bolts 8 on the outer sides of the four connecting seats 7 are loosened, and the bidirectional motor 2 is started to lift the moving frame 6. When it is lifted to a suitable height, the four locking bolts 8 on the outer sides of the four connecting seats 7 are tightened.

[0032] On the two support columns 23, adjust the positions of the two sliders 25 so that the two connecting bolts 26 on the sliders 25 correspond to the positions of the two screw holes 17, then tighten the threads to connect the load-bearing plate 16 and the support columns 23, and then pull the connecting plate 21, and then pull the load-bearing plate 16 out of the moving frame 6, and pick up the required goods on the load-bearing plate 16, so that the required goods can be picked up without adjusting the shelves layer by layer, making it more convenient to pick up the goods. After picking up the goods, push the connecting plate 21 to the original position and loosen the two connecting bolts 26.

[0033] When it is necessary to pick up the goods on another moving frame 6, the first bolts 13 on the two pairs of protrusions 10 on the moving frame 6 that has already picked up the goods are loosened, and the two pairs of protrusions 10 are slid on the slide groove 9 to separate them from each other, and then the above-mentioned picking operation is performed on the goods on the other moving frame 6.

[0034] When goods need to be stored, the two support columns 23 are moved to both sides of all movable frames 6 through the second slide rails 22 to avoid the two support columns 23 causing obstacles to the storage of goods when goods are stored on the carrying plate.

[0035] All the moving frames 6 on the first screw rod 3 and the second screw rod 4 are limited by the first limiting plate 18 and the second limiting plate 19 to prevent the moving frames 6 from moving to a height exceeding the four vertical guide pillars 5 and causing the goods on the carrying plate 16 to fall off.

[0036] Two wheels 27 are provided at the bottom of the connecting plate 21. The two wheels 27 are in contact with the ground to support the connecting plate. During the picking process, when the connecting plate 21 is pulled to drive the carrying plate 16 to move, the wheels 27 can save effort.
