[0040] This embodiment has the following advantages:

[0041] After the goods move sideways, the corner ribs 13 provide support force to the side shift frame 12 at the corners of the side shift frame 12, which can effectively prevent the side shift frame 12 from being deformed. Through the arrangement of the first fixed seat 14 and the second fixed seat 15, the support rod 16 can make the connection between the support rod 16 and the side shift frame 12 more stable. While the support rod 16 supports the first sliding seat 21 and the second sliding seat 22, the two ends of the support rod 16 can also provide support force to the side shift frame 12 through the first fixed seat 14 and the second fixed seat 15, so that the side shift frame 12 remains stable and prevents the side shift frame 12 from being deformed. The first driving member 31 and the second driving member 32 are staggered, so that while ensuring that the first driving member 31 and the second driving member 32 do not interfere with each other in space, the overall structure of the side shift frame 12 can be made more compact, and the structural reliability of the side shift frame 12 can also be improved. Through the design of various structures, the structural reliability of the side shift frame 12 can be effectively improved, and the side shift frame 12 can be prevented from deforming after side shifting, thereby effectively improving the reliability of the overall structure and achieving the advantage of better reliability.

[0042] By extending and shortening the first hydraulic cylinder and the second hydraulic cylinder, the first sliding seat 21 and the second sliding seat 22 are driven to slide on the support rod 16, thereby driving the first sliding seat 21 and the second sliding seat 22 to slide and drive the fork assembly to move, thereby achieving the function of adjusting the distance between the two fork arms 23.

[0043] The oil pipe on the forklift is connected to the oil light connection block, and hydraulic oil is injected into the first connecting pipe 34 and the second connecting pipe 35 through the forklift, so that the first hydraulic cylinder and the second hydraulic cylinder can be pushed to move by the hydraulic oil. The first hydraulic cylinder and the second hydraulic cylinder are connected in series through the first connecting pipe 34, the second connecting pipe 35, and the third connecting pipe 36. When hydraulic oil is injected into the first connecting pipe 34, the hydraulic oil drives the piston rods of the first hydraulic cylinder and the second hydraulic cylinder to extend at the same time. When hydraulic oil is injected into the second connecting pipe 35, the hydraulic oil drives the piston rods of the first hydraulic cylinder and the second hydraulic cylinder to retract into the cylinder barrel at the same time, thereby realizing the function of synchronously driving the first hydraulic cylinder and the second hydraulic cylinder.

[0044] The side-shift driving member 41 drives the sliding plate 45 to slide on the fixed frame 11. The sliding plate 45 drives the active rack 42 during the sliding process. The active rack 42 drives the driven rack 44 to move in the opposite direction through the gear 43, so that the side-shift frame 12 can be driven to move through the driven rack 44, thereby realizing the function of the side-shift driving mechanism driving the side-shift frame 12 to move on the fixed frame 11.

[0045] The active rack 42 and the driven rack 44 are respectively located on both sides of the gear 43 to prevent the active rack 42 and the driven rack 44 from colliding during movement, thereby improving reliability.

[0046] During the process of the side shifting driving member 41 and the side shifting frame 12 moving in opposite directions, the side shifting driving member 41 drives the counterweight block 46 to move, so that the counterweight block 46 and the side shifting frame 12 move in opposite directions, so that the lateral torque generated by the displacement of a part of the side shifting frame 12 can be balanced by the counterweight block 46, thereby effectively improving the balance of the overall structure when the side shifting frame 12 drives the cargo to move sideways, reducing the risk of rollover, and achieving the advantage of higher reliability.

[0047] The sliding plate 45 is clamped by the clamping plate 47 to prevent the sliding plate 45 from being separated from the fixing frame 11 , thereby improving the structural stability between the sliding plate 45 and the fixing frame 11 .

[0048] The first avoidance groove 24 and the second avoidance groove 25 are provided to prevent the first sliding seat 21 and the second sliding seat 22 from getting stuck with each other during the movement of the two fork arms 23, thereby increasing the movement stroke of the first sliding seat 21 and the second sliding seat 22 and achieving the effect of convenient use.

[0049] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
