The rear end of the upper support frame 104 is close to the feed port of the shelf, and the telescopic end of the first electric push rod 110 is extended. The upper support frame 104 moves backward and downward as a whole, so that the rear end of the upper support frame 104 slowly extends into the shelf, and the first electric push rod 110 stops running.
[0026] Move the handle 209 to the left or right, the handle 209 rotates around the rotating shaft 208 and compresses the spring piece 211, the lower end of the handle 209 separates from the first limiting groove 120, and pushes the movable seat 201 backward. When the handle 209 moves to the side of the second limiting groove 105, release the handle 209, the spring piece 211 straightens the handle 209, the lower end of the handle 209 is plugged into the second limiting groove 105, and the movable seat 201 stops moving; the telescopic end of the second electric push rod 203 contracts and drives the support seat 202 to move downward. Under the sliding cooperation of the second slider 205 and the second slide rail 206, the support seat 202 drives the item support plate 207 and the items to be stored to move downward, and the lower surface of the item support plate 207 contacts the item placement table in the shelf.
[0027] The second electric push rod 203 continues to contract, so that the support seat 202 is separated from the item support plate 207. The handle 209 is moved left or right, and the lower end of the handle 209 is separated from the second limiting groove 105, and the movable seat 201 is pulled forward, and the support seat 202 is moved away from the top of the item placement table. When the handle 209 moves to the side of the first limiting groove 120, the handle 209 is released, and the spring 211 straightens the handle 209, and the lower end of the handle 209 is plugged into the first limiting groove 120, and the movable seat 201 stops moving. The telescopic end of the first electric push rod 110 contracts, driving the upper support frame 104, the movable seat 201 and the support frame 202 to move forward, and the lower support frame 101 is pulled forward, and the lower support frame 101 drives the upper support frame 104, the movable seat 201 and the support frame 202 to move out of the shelf, completing the item transportation and unloading process.
[0028] When items need to be taken out for use, the device is used to load and take out the items to be stored. The working principles of the loading process and the unloading process are similar, so they are not described in detail.
[0029] It should be noted that the movements of the first electric push rod 110 and the second electric push rod 203 are controlled by a commercially available industrial control integrated computer, and the rechargeable power supply 121 provides power supply for the first electric push rod 110, the second electric push rod 203 and the industrial control integrated computer.
