The transmission shaft 13 is driven to rotate by the driving motor 12, so that the transmission shaft 13 drives the walking wheels 14 to walk on the top of the walking track 11, and the shuttle vehicle achieves the function of walking on the walking mechanism 1.

[0032] The stacking mechanism 4 is slidably mounted on the guide column 16. The stacking mechanism 4 comprises two sets of stacking frames 41, two sets of extension frames 431 fixedly mounted on the two ends of the stacking frames 41, a drive shaft 43 driving the two sets of extension frames 431 inside, and a main shaft motor 42 driving the drive shaft 43 to rotate. The stacking frames 41 are fixedly mounted with two sets of pull side plates 44 on one side, and the fixed plate 21 is fixedly mounted at the bottom position of the pull side plate 44 on one side of the conveying mechanism 2. The fixed plate 21 is fixedly mounted with a docking gear frame 46 on the top, and the lifting gear 353 and the docking gear frame 46 are connected and driven by the lifting chain 352. The lifting chain 352 is fixedly mounted at both ends with the pull side plate 44. When the lifting gear 353 fixedly mounted at both ends of the output shaft 35 rotates, the pull side plate 44 is pulled by the lifting chain 352, and the other end of the lifting chain 352 is fixedly mounted on the conveying mechanism 2 by the docking gear frame 46, so that the whole stacking frame 41 moves up and down within the height range of the guide column 16, realizing the function effect of the upward and downward movement of the stacking frame 41. The extension frame 431 is fixedly mounted on the stacking frame 41, the drive shaft 43 is fixedly mounted through the bearing seat penetrating the extension frame 431, and the main shaft motor 42 is fixedly mounted between the two sets of drive shafts 43. The drive shaft 43 is fixedly mounted with a drive gear 432 inside the extension frame 431, the bottom of the drive gear 432 is meshingly mounted with a transmission rack 433, the bottom of the transmission rack 433 is slidably mounted inside the extension frame 431, and the end of the transmission rack 433 is fixedly mounted with an extension plate 434. The main shaft motor 42 drives the two sets of drive shafts 43 to rotate, thereby driving the drive gear 432 to rotate, driving the transmission rack 433 and the extension plate 434 fixedly mounted with the transmission rack 433 to move, thereby controlling the extension or retraction of the goods by the extension plate 434, cooperating with the pulling of the pull side plate 44 by the lifting chain 352, so that the whole stacking frame 41 moves up and down within the height range of the guide column 16, realizing the function of unfolding and folding the goods.

[0033] The structural diagram is as follows Figures 6-7As shown. The two ends of the spindle motor 42 are slidably installed with the guide column 16 through a pulley mechanism 45. A limit bar 161 is installed on the guide column 16. The pulley mechanism 45 includes two sets of pulleys 452 and a pulley frame 451 slidably installed with the pulley 452. A slide groove 458 is provided inside the pulley frame 451, and a rotating block 455 is installed at one end of the pulley frame 451, and a slider 456 is installed at one end of the rotating block 455, and the slider 456 slides in cooperation with the slide groove 458. A connecting rod 457 is fixedly installed at one end of the slider 456, and a fastening spring 459 is fixedly installed between the pulley frames 451 and fixedly installed with the end of the connecting rod 457. A docking plate 453 is fixedly installed at the top and bottom of the pulley frame 451, and a mounting hole 454 is provided on the docking plate 453. When the stacking frame 41 cooperates with the lifting chain 352 to pull up and down, the pulley mechanism 45 guides and limits the lifting process during unstacking. During the unstacking process, if the goods are subjected to external forces, the fastening springs 459 installed between the pulleys 452 will limit the position of the two sets of pulleys 452 to prevent them from separating from the outer surface of the guide column 16. This ensures that the pulley mechanism 45 always assists in sliding on the guide column 16. This prevents the swaying of the goods from causing deviations in the stacking position, which can lead to unstable center of gravity caused by stacking multiple groups at different positions. If the goods are affected by external forces during the lifting process, the fastening springs 459 between the pulleys 452 can also buffer the swaying, thereby ensuring the stability of the goods during the lifting and lowering process.

[0034] First, the drive motor 12 drives the transmission shaft 13, causing it to rotate and drive the running wheels 14 along the top of the running track 11. The transmission chain 342 then connects the transmission gear set 341 and the auxiliary gear 351. When the lifting motor 34 is driven, the output shaft 35 rotates, which in turn rotates the lifting gears 353 fixed at both ends of the output shaft 35. The lifting chain 352 lifts the lifting side plate 44, while the other end of the lifting chain 352 is fixed to the side of the conveyor mechanism 2 by the docking gear rack 46. This allows the stacking frame 41 to be lifted and moved up and down within the height range of the guide column 16, achieving the functional effect of the stacking frame 41 moving up and down. The spindle motor 42 drives the two sets of drive shafts 43 to rotate, driving the drive gear 432 to rotate, so that the drive gear 432 drives the transmission rack 433 and the extension plate 434 fixedly installed with the transmission rack 433 to move, thereby controlling the extension plate 434 to extend or retract the goods, and cooperating with the lifting chain 352 to lift the lifting side plate 44, so that the stacking frame 41 as a whole can be lifted and moved up and down within the height range of the guide column 16, realizing the functionality of stacking and unstacking the goods.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
