[0026] When using the device, the worker first adjusts the distance between the two limiting plates 9 according to the width of the shelf, and the specific operation is as follows: the worker first controls the cylinder 4 to drive the fixed seat 5 to move downward, so as to drive the sliding plate 7 and the limiting plate 9 to move outward through the connecting plate 6, when the distance between the two limiting plates 9 is adjusted to exceed the width of the shelf, the fork carriage 3 of the stacker 1 is extended into the shelf directly below, when the shelf is against the fork carriage 3, the first electric guide rail 2 is controlled to drive the fork carriage 3 to move upward to the appropriate height to hold the shelf, then the cylinder 4 is immediately controlled to drive the fixed seat 5 to move upward, the fixed seat 5 will drive the sliding plate 7 and the limiting plate 9 to move inward to contact the shelf through the connecting plate 6, the inward moving limiting plate 9 will clamp the left and right sides of the shelf, then continue to operate the stacker 1 to the destination, the worker can control the first electric guide rail 2 to drive the fork carriage 3 to move downward to put the shelf on the ground, continue to refer to the previous steps to make the limiting plate 9 move outward to separate from the shelf, finally operate the stacker 1 to withdraw the fork carriage 3 from below the shelf, as described above, the limiting plate 9 can limit the left and right sides of the shelf, avoid the left and right deviation of the shelf during the carrying process, and prevent the goods from falling and damaging, improve the work efficiency.

[0027] Embodiment 2

[0028] On the basis of embodiment 1, as shown in Figure 1 、 Figure 4 and Figure 5 , it further includes a top plate 10, a positioning plate 11, a second electric guide rail 12, a sliding seat 13, a rotating shaft 14, a fixed plate 15 and a torsional spring 16, the top plate 10 is fixedly connected to the rear side of the fork carriage 3, the positioning plate 11 is fixedly connected to the rear part of the top plate 10, the second electric guide rail 12 is installed on the lower part of the top plate 10, the sliding seat 13 is slidingly connected to the second electric guide rail 12, the rotating shaft 14 is rotatably connected to the front part of the sliding seat 13, the fixed plate 15 is fixedly connected to the rotating shaft 14, and the torsional spring 16 is connected between the left and right sides of the fixed plate 15 and the sliding seat 13, and the left and right torsional springs 16 are wound around the rotating shaft 14.

[0029] When the rack is lifted from the ground by the forklift 3, the operator can control the second electric guide rail 12 to move the slide 13 backward, thereby causing the rotating shaft 14 and the fixing plate 15 to move backward together. The backward-moving fixing plate 15 is blocked by the top plate 10, causing the fixing plate 15 to rotate together with the rotating shaft 14. The fixing plate 15 flips upward 90 degrees to stand upright, and the torsion spring 16 is twisted. As the slide 13 continues to move backward, the upright fixing plate 15 and the positioning plate 11 will clamp the front and rear sides of the rack. Continue to refer to the previous steps. The shelf is moved to its destination, and the second electric guide rail 12 continues to drive the slide 13 forward, thereby driving the rotating shaft 14 and the fixed plate 15 forward. When the fixed plate 15 moves forward and separates from the top plate 10, the fixed plate 15 flips down and resets under the action of the torsion spring 16. In summary, the positioning plate 11 and the fixed plate 15 limit the front and rear sides of the shelf, preventing the shelf from sliding forward due to braking or downhill during the handling process, which may cause the goods to fall and be damaged, thus improving the efficiency of goods transportation.

[0030] like Figure 1 and Figure 6 As shown, it also includes mounting plates 17 and electric push rods 18. There are two mounting plates 17, which are fixed to the left and right sides of the stacker truck 1 respectively. The electric push rods 18 are installed on the top of the fork frame 3. Ten locking holes are opened on the mounting plates 17 on both the left and right sides.

[0031] When stacking shelves, to prevent a safety accident caused by the first electric guide rail 2 malfunctioning and the raised shelves falling vertically, the fork carriage 3 can be limited. The specific operation is as follows: When the fork carriage 3 raises the shelf to the specified height, the operator can first control the telescopic end of the electric push rod 18 to extend to the left and right sides until it passes through the locking hole. After stacking is completed, the telescopic end of the electric push rod 18 is then controlled to retract inward until it separates from the locking hole. In summary, the electric push rod 18 and the mounting plate 17 can limit the fork carriage 3, preventing damage to the shelf on the fork carriage 3 due to collision with the ground caused by a braking problem of the first electric guide rail 2 during stacking, thus improving the safety of the device.

[0032] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
