[0031] As Figure 1 and 8 shown, a multi-layer rack type electric turnover cart includes a frame body 1, a multi-layer material rack 2, and a handling rack 3. The multi-layer material rack 2 and the handling rack 3 are arranged on the frame body 1. The multi-layer material rack 2 is used for storing trays. The handling rack 3 includes a lifting device 31 and a fork lifting bucket 32. The lifting device 31 is slidably connected to the fork lifting bucket 32. The fork lifting bucket 32 is provided with a telescopic fork 4 and is located between the fork lifting bucket 32 and the multi-layer material rack 2. A fork shifting mechanism 5 is horizontally arranged on the fork lifting bucket 32. The fork shifting mechanism 5 is used to push the fork lifting bucket 32 to move in the horizontal direction.

[0032] Specifically, the forklift lifting bucket 32 uses the telescopic forklift 4 to fork the tray from the shelf, and then the lifting device 31 drives the forklift lifting bucket 32 to lift and slide to the same horizontal height as one of the layers of the multi-layer material rack 2. The telescopic forklift 4 forks the tray, and then the tray can be horizontally moved to the multi-layer material rack 2 under the drive of the fork mechanism 5. The multi-layer material rack 2 can store multiple trays, and multiple trays can be transported at one time, improving the material turnover efficiency. It should be noted that sensors (not shown in the figure) are provided on the forklift lifting bucket 32 to detect whether the position of the telescopic forklift 4 matches the position of the tray on the shelf when the transfer vehicle runs and stops in front of the shelf, and transmit the information to the control system of the transfer vehicle (not shown in the figure).

[0033] Further, the lifting device 31 includes a lifting door body 311 and a door body push cylinder 312. The lifting door body 311 is provided with a lifting guide rail 313 and a lifting mechanism 314. A plurality of guide wheels 315 are installed at the bottom of the lifting door body 311. One end of the door body push cylinder 312 is connected to the lifting door body 311, and the other end is fixedly arranged on the vehicle frame body 1.

[0034] Further, the forklift lifting bucket 32 includes a forklift base 321, a base rotating mechanism 322, a base sliding mechanism 323, a lifting bucket bracket 324 and a base push cylinder 325. The base sliding mechanism 323 is arranged on the lifting bucket bracket 324, the base rotating mechanism 322 is arranged on the base sliding mechanism 323, the forklift base 321 is arranged on the base rotating mechanism 322, and the telescopic forklift 4 is connected to the forklift base 321.

[0035] It should be noted that a plurality of universal balls (not shown in the figure) are also provided above the forklift base 321, and the conveying surface of the universal balls is higher than the conveying surface of the telescopic forklift 4.

[0036] Further, the lifting bucket bracket 324 is provided with a chain connection mechanism 326, a lifting slider 327 and a lifting roller assembly 328. The chain connection mechanism 326 is connected to the lifting mechanism 314 through a chain, and the lifting slider 327 is slidably connected to the lifting guide rail 313, so that the forklift lifting bucket 32 can slide up and down along the lifting device 31.

[0037] Further, the fork mechanism 5 includes a fork body 51, on which a rack 52, a gear member 53 and a guiding slide rail 54 are provided. The rack 52 and the guiding slide rail 54 are horizontally arranged on the fork lifting bucket 32. The rack 52 is connected to the guiding slide rail 54. The fork body 51 is slidably connected to the guiding slide rail 54, and the gear member 53 is rotatably connected to the rack 52. Thus, when the rack 52 rotates, it pushes the fork body 51 to slide along the guiding slide rail 54, and further pushes the telescopic fork 4 of the fork lifting bucket 32 to move.

[0038] Specifically, when the door pushing cylinder 325 works, the door pushing cylinder 325 pushes the lifting door body 311 to slide in the wheel groove (not shown in the figure) on the vehicle frame body 1, so that the handling rack 3 can slide on the vehicle frame body 1, which is beneficial to the work of the fork lifting bucket 32. When the telescopic fork 4 needs to fork a tray from the shelf, the base rotating mechanism 322 drives the fork base to rotate 322 towards the shelf to fork the tray, and then rotates towards the multi-layer material rack 2. The door pushing cylinder 325 can push the handling rack 3 and the multi-layer material rack 2 to a suitable position. Driven by the lifting mechanism 314, the fork lifting bucket 32 can slide up and down along the lifting guide rail 313 to the same horizontal height of one layer of the multi-layer material rack 2. The moving direction of the fork mechanism 5 is perpendicular to the telescopic fork 4. The tray fork-lifted by the telescopic fork 4 can be horizontally moved to the multi-layer rack 2 for storage under the drive of the fork mechanism 5.

[0039] It should be noted that the base pushing cylinder 325, the base sliding mechanism 323 and the base rotating mechanism 322 are all equipped with servo motors (not shown in the figure). The control system carried on the transfer cart can control the servo motors according to the information fed back by the sensors, and automatically adjust the position of the telescopic fork 4 to ensure that the telescopic fork 4 is accurate when extending to fork or place the tray and does not collide with the shelf.

[0040] Further, swing rods 511 and fixed rods 512 are provided at both ends of the fork body 51.

[0041] Further, the multi-layer material rack 2 includes a rack body 21 and a plurality of single-layer racks 23 formed by a rack roller assembly 22. The rack roller assembly 22 is used to move the tray.

[0042] Further, the telescopic fork 4 includes an upper fork 41, a middle fork 42 and a bottom fork 43 from top to bottom. First hooks 44 and second hooks 45 are further provided at the front and rear ends of the upper fork. The hooks are used to fork and place the tray.

[0043] Specifically, the multi-layer material rack 2 is used to store trays. Each single-layer rack 23 can store a tray separately. The trays fork-lifted and placed by the telescopic fork 4 can be laterally transported to the multi-layer material rack 2 through the fork mechanism 5 and the rack roller assembly 22.

[0044] Further, a drive wheel 6, a steering mechanism 7, a secondary wheel 8, a standing board 9 and a battery pack 10 are also provided on the frame body 1. The standing board 9 is for the operator to stand on, and the steering mechanism 7 is for controlling the frame body 1.

[0045] After the operator only needs to control the system on the standing board 9 to stop the transfer vehicle at the designated position, the telescopic fork 4 of the electric transfer vehicle can automatically adjust the alignment with the shelf, and automatically complete the picking or placing of the tray without manual operation, which is both safe and efficient.

[0046] Working steps:

[0047] When the telescopic fork 4 picks up the tray on the shelf and moves it to the transfer vehicle, the movement path A of the telescopic fork is as follows:

[0048] A1: The first hook 44 and the second hook 45 of the upper fork 41 are in the lying state, and the telescopic fork 4 extends and moves to the picking position;

[0049] A2: The first hook 44 is erected, the telescopic fork 4 retracts, the first hook 44 hooks the tray, and the tray moves towards the electric transfer vehicle driven by the telescopic fork 4;

[0050] A3: After the telescopic fork 4 retracts and moves to a reasonable position, the telescopic fork 4 extends a short distance again, the first hook 44 lies down, and the telescopic fork 4 moves back to the control set origin.

[0051] When the telescopic fork 4 places the tray from the transfer vehicle onto the shelf, the movement path B of the telescopic fork 4 is as follows:

[0052] B1: The first hook 44 is in the lying state, the second hook 45 is erected, the telescopic fork 4 extends, and the second hook 45 hooks the tray, and the tray leaves the electric transfer vehicle driven by the telescopic fork 4;

[0053] B2: The tray moves to a reasonable position on the shelf driven by the telescopic fork 4, the telescopic fork 4 moves back to the control set origin, and the second hook 45 lies down.

[0054] The movement path C of the tray from the fork lifting bucket 32 into the multi-layer material rack 22 is as follows:

[0055] C1: The lifting mechanism 314 works under the control of the control system, driving the fork lifting bucket 32 and the tray to lift to a position flush with a certain single-layer rack 23 on the multi-layer material rack 2;

[0056] C2: The tray is located on the forklift fork base 321. The fork body 51 is driven to move horizontally by the mutual rotation of the gear member 53 and the rack 52. The fixed lever 512 hooks the tray and drives the tray to move towards the multi-layer material rack 2. After the fork body 51 moves in place, it returns to the origin.

[0057] C3: The rack roller assembly 22 and the lifting bucket roller assembly 328 work under the control of the control system. The tray is transported to the multi-layer material rack 2. After the tray is transported to the single-layer rack 23, the rack roller assembly 22 and the lifting bucket roller assembly 328 stop working under the control of the control system.

[0058] C4: The lifting mechanism 314 works under the control of the control system and drives the forklift fork lifting bucket 32 to return to the origin.

[0060] D1: The lifting mechanism 314 works under the control of the control system and drives the forklift fork lifting bucket 32 and the tray to lift to a position flush with a certain single-layer rack 23 on the multi-layer material rack 2.

[0061] D2: The tray is located on the single-layer rack 23 of the multi-layer material rack 2. The rack roller assembly 22 and the lifting bucket roller assembly 328 work under the control of the control system and drive the tray to be horizontally transported away from the multi-layer material rack 2.

[0062] D3: After the tray is horizontally transported to a certain position, the fork body 51 is driven to move towards the multi-layer material rack 2 by the mutual rotation of the gear member 53 and the rack 52. After moving in place, the swinging lever 511 swings downward. Then, the fork body 51 is driven to move towards the forklift fork lifting bucket 32 by the mutual rotation of the gear member 53 and the rack 52. After the swinging lever 511 hooks the tray, it drives the tray to move towards the forklift fork lifting bucket 32. After the fork body 51 moves in place, the swinging lever 511 swings upward to return to the origin.

[0063] D4: The rack roller assembly 22 and the lifting bucket roller assembly 328 stop working under the control of the control system.
