[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figure 1-3 As shown, a picking vehicle suitable for Australian pallets includes a body component 2, a lifting component 3 and a fork component 4. The Australian pallet 1 includes a top frame 11 and a bottom frame 12 fixed below the top frame 11. A gap is provided between the top frame 11 and the bottom frame 12 for inserting a fork 41 of the picking vehicle. The bottom frame 12 is provided with a through slot 121. The body component 2 includes a body 21 and a frame 22 located at the front side of the body 21. The lifting component 3 includes a lifting frame 31 that can be lifted and lowered on the frame 22. The fork component 4 includes a fork 41 connected to the lifting frame 31 at the rear end, and a support located at the bottom of the fork 41. The support wheel 42 and the guide member are arranged obliquely at the bottom of the front end of the fork 41, the support wheel 42 is located at the rear side of the guide member, and the minimum height of the guide member is higher than the minimum height of the support wheel 42. When the fork 41 is inserted into the gap between the top frame 11 and the bottom frame 12, the guide member first abuts against the top surface of the bottom frame 12. At this time, the guide member plays a role of inclined guidance, which is convenient for the support wheel 42 to pass over the border of the bottom frame 12 and improve its passability. When the support wheel 42 enters the through slot 121, it can pass through the through slot 121 and abut against the ground to support the fork 41 and the Australian pallet 1.

[0028] In this embodiment, the guide member includes a plurality of guide wheels 43, and the plurality of guide wheels 43 are arranged obliquely at the bottom of the fork 41 along the length direction of the fork 41, and the heights of the plurality of guide wheels 43 increase successively from the back to the front, and the bottom heights of the plurality of guide wheels 43 are all higher than the bottom height of the support wheel 42. The guide wheel 43 guides the support wheel 42 in an oblique arrangement so that it can smoothly enter the gap. At the same time, when the support wheel 42 passes through the through slot 121 and abuts against the ground, the guide wheel 43 can abut against the top of the bottom frame 12, and at the same time, it can also prevent the fork 41 from abutting against the top of the bottom frame 12, thereby protecting the fork 41.

[0029] Of course, the guide member may also be other guide members, such as a guide slide, which should not exceed the protection scope of this application.

[0030] In order to further improve the passability of the support wheel 42, the lifting assembly 3 also includes a counterweight block 32, which is fixed on the lifting frame 31. The tail end of the fork 41 is hinged on the bottom end of the lifting frame 31 and can rotate in the up and down directions. When the counterweight block 32 is applied, it can press down the tail end of the fork 41, and then slightly lift the front end of the fork 41, driving the support wheel 42 to lift upward, so as to increase the height of the support wheel 42, thereby improving the passability of the support wheel 42.

[0031] Specifically, the lifting assembly 3 also includes a lifting cylinder 33, which is arranged on the frame 22 in the vertical direction, and a piston rod is provided at the top of the lifting cylinder 33, which is connected to the lifting frame 31. The lifting cylinder 33 drives the lifting frame 31 to perform lifting and lowering movements through the piston rod, thereby driving the fork 41 to lift and lower. During the descending process, the piston rod often fails to descend into place, and the fork 41 cannot descend into place at this time. In order to solve this problem, the lifting assembly 3 also includes a return spring 34, the lower end of which is fixed on the frame 22, and the upper end of the return spring 34 is connected to the lifting frame 31. When the lifting cylinder 33 drives the lifting frame 31 to descend, the return spring 34 is in a stretched state, and the return spring 34 will continue to pull the lifting frame 31 downward, so that the piston rod can be reset to the lowest position.
