[0029] The heavy cargo handling auxiliary mechanism 5 includes a first adjustment component 51 and a second adjustment component 52 . The first adjustment component 51 is arranged outside the second adjustment component 52 .

[0030] Furthermore, the first adjustment component 51 includes a motor base 511, which is fixedly installed inside the first mounting frame 4, a driving motor 512 is fixedly installed inside the motor base 511, a connecting column 513 is fixedly installed on the output shaft of the driving motor 512, a gear 514 is fixedly installed outside the connecting column 513, a second mounting frame 515 is fixedly installed inside the first mounting frame 4, a rack plate 516 is slidably installed inside the second mounting frame 515, and a first adjustment baffle 517 is fixedly installed outside the rack plate 516, so as to facilitate the synchronous adjustment of the two groups of first adjustment baffles 517 to increase the placement space and limit the position of heavy goods.

[0031] Furthermore, two groups of the second mounting frame 515 , the rack plate 516 , and the first adjustment baffle 517 are provided, and the rack plate 516 is meshed with the gear 514 , so as to facilitate further adjustment of the space on both sides.

[0032] Furthermore, the second adjustment component 52 includes a worm 521 and a mounting frame 522. The worm 521 is fixedly installed on the top of the connecting column 513, and the mounting frame 522 is fixedly installed on the top of the second mounting frame 515. A screw 523 is rotatably installed inside the mounting frame 522, and a worm gear 524 is fixedly installed outside the screw 523. A limiting plate 525 is fixedly installed outside the mounting frame 522, and a second adjustment baffle 526 is threadedly installed on the outside of the screw 523 to facilitate adjustment of the position of the second adjustment baffle 526.

[0033] Furthermore, through holes are opened at corresponding positions of the second adjustment baffle 526 and the limiting plate 525, the limiting plate 525 passes through the through holes, and the worm wheel 524 is meshed with the worm 521 to prevent the second adjustment baffle 526 from rotating as the screw 523 rotates.

[0034] Embodiment 2:

[0035] See also Figure 5 In combination with the first embodiment, it is further obtained that the auxiliary shock-absorbing mechanism 6 includes a connecting frame 61, the connecting frame 61 is fixedly installed at the bottom of the lifting frame 3, and a mounting bottom frame 62 is fixedly installed on the side of the connecting frame 61 away from the lifting frame 3. A shock-absorbing spring 63 is arranged inside the mounting bottom frame 62, and a damper body 64 is arranged inside the shock-absorbing spring 63. A connecting top plate 65 is fixedly installed on the top of the shock-absorbing spring 63, which is convenient for providing a certain buffer for heavy goods when loading and unloading.

[0037] In actual operation, when this device is used, the AGV forklift body 1 is first driven to the required location. When heavy goods need to be transported, the lifting device 2 and the lifting frame 3 are first operated to make the first installation frame 4 fall to the bottom, and then the driving motor 512 is turned on to rotate the connecting column 513, so that the gear 514 rotates synchronously, so that the two sets of rack plates 516 set inside the second installation frame 515 slide back to back, so that the first adjustment baffle 517 set is expanded outward, and at the same time, under the rotation action of the connecting column 513, the set worm 521 can be rotated to rotate the worm wheel 524 meshing therewith, so that the screw 523 rotates, and under the action of the limit plate 525, the set second adjustment baffle 526 can be moved outside the screw 523 to increase the space for placing heavy goods, and then the goods are moved to the top of the first installation frame 4, and the shock absorbing spring 63 and the damper itself are used to adjust the baffle plate 526. Under the cooperation of the body 64 and the connecting top plate 65, the heavy goods just placed can be buffered to a certain extent to avoid the heavy goods from shaking greatly when being placed. Subsequently, in order to avoid the heavy goods from falling off and being damaged during transportation, the driving motor 512 can be turned on to make the connecting column 513 rotate in the opposite direction, so that the set gear 514 and the worm 521 rotate in the opposite direction, so that the first adjusting baffle 517 and the second adjusting baffle 526 are retracted, so as to realize the positioning of the heavy goods on the top of the first installation frame 4, and avoid the heavy goods from slipping and being damaged during transportation. After being transported to the required location, during the placement process, the first adjusting baffle 517 and the second adjusting baffle 526 can be unfolded, and under the action of the shock-absorbing spring 63, the damper body 64, and the connecting top plate 65, buffering can be achieved during placement to ensure smooth unloading.
