In this embodiment, the traversing lifting assembly 6 includes a leg assembly 601, a first driving cylinder 602, a second driving cylinder 603, and a track assembly 604, where the first driving cylinder 602 drives the leg assembly 601, so as to lift the leg assembly 601, the leg assembly 601 is mounted on the track assembly 604 through a pulley, adjacent leg assemblies 601 are connected together through a side-shifting frame assembly 605, and the second driving cylinder 603 drives the leg assembly 601 to move left and right, so as to drive the platform assembly 1 to traverse or lift.
Further, the shaping device 7 is arranged at the left side and the right side of the platform assembly 1.
The side shaping device 7 of this embodiment includes roller rows, and is disposed on the left and right sides of the platform assembly 1, so that the left and right sides of the pallet of the cargo can be shaped and the cargo can be arranged neatly in the process of forward output of the cargo through the lifting fork assembly 2 and the chain assembly 4.
Further provided is a control method of the fork loading system, based on the fork loading system, in the process that the lifting fork assembly 2 lifts the outer fork 202, the chain assembly 4 is controlled to drive the lifting fork assembly 2 to move so as to offset the horizontal displacement component of the outer fork 202.
In the process of lifting the outer fork 202 by the fork assembly 2, the driving piece 203 drives the outer fork 202 to transversely move, the roller 2021 and the inclined block 2011 cooperate in the process of transversely moving the outer fork 202 so as to lift the outer fork 202, at this moment, the moving direction of the outer fork 202 moves obliquely upwards, in the moving process, the outer fork 202 and the bottom of the tray generate transverse relative displacement, on one hand, the tray generates friction force on the outer fork 202, so that the outer fork 202 is difficult to transversely move, and on the other hand, the driving piece 203 is required to do additional work when the outer fork 202 lifts and transversely moves the goods. Thus, in the lifting process, for example, the outer fork 202 is pulled backward by the driving member, the chain assembly 4 drives the lifting fork assembly 2 to move forward, and the speed of pulling the outer fork 202 backward by the driving member in the lifting process is the same as the speed of driving the lifting fork assembly 2 to move forward by the chain assembly 4, so that the lateral position of the outer fork 202 relative to the platform assembly 1 is not changed, and the cargo is lifted.
