The application principle of the flat light-load four-way shuttle vehicle of the exemplary embodiment of the utility model is as follows:
the two adjusting slide blocks 124 sleeved on the two-way screw rod 123 are internally provided with opposite internal threaded holes, and the driving direction of the screw rod driving motor 121 is controlled by the controller 14 to enable the two-way screw rod 123 to rotate forward or backward, so that the two adjusting slide blocks 124 on the same two-way screw rod 123 move oppositely or oppositely.
When the two adjusting sliders 124 on the same bidirectional screw rod 123 move back to back, the outer bearings 126 in the first guide rail 22 also move back to back, and under the action of the shape of the first guide rail 22, the lower frame module 1 and the middle frame module 2 approach each other, so that the second driving wheel set 231 and the second driven wheel set 232 descend to contact with the transverse rail 6, and the first driving wheel set 131 and the first driven wheel set 132 ascend, thus completing one-time switching of the traveling direction. At the same time, the inner bearings 127 located in the second guide rails 32 are also moved away from each other, and the upper frame module 3 and the middle frame module 2 approach each other by the shape of the second guide rails 32, i.e., the lowering of the upper frame module 3 is achieved.

In practical application, as shown in fig. 6, the flat light-load four-way shuttle vehicle of the embodiment can lift the feed box 4, and when the upper frame module 3 descends or ascends in the vertical direction, the feed box 4 can be lifted or put down.
When the two adjusting sliders 124 on the same bidirectional screw rod 123 move in opposite directions, the outer bearings 126 in the first guide rail 22 also move in opposite directions synchronously, and the lower layer frame module 1 and the middle layer frame module 2 are far away from each other under the shape of the first guide rail 22, so that the first driving wheel set 131 and the first driven wheel set 132 descend to contact with the longitudinal rail 5, and the second driving wheel set 231 and the second driven wheel set 232 ascend to complete one-time switching of the traveling direction. At the same time, the inner bearings 127 located in the second guide rails 32 are also moved toward each other, and the upper frame module 3 and the middle frame module 2 are separated from each other by the shape of the second guide rails 32, that is, the upper frame module 3 is lifted.
Through the switching of the traveling direction, the flat light-load four-way shuttle in the embodiment can travel in a track architecture system formed by a longitudinal track 5 and a transverse track 6 which are in a mutually perpendicular relationship. Fig. 7 shows an example of a state of the flat light-load four-way shuttle of the present embodiment when walking on the longitudinal rail 5, when the flat light-load four-way shuttle walks on the longitudinal rail 5, the first driving wheel group 131 of the first traveling mechanism 13 walks on the longitudinal rail 5, and the guide wheel 212 rolls on the inner side of the longitudinal rail 5, so as to ensure that the flat light-load four-way shuttle does not directly contact with the longitudinal rail 5. Fig. 8 is a diagram showing an example of a state in which the flat light-load four-way shuttle of the present embodiment walks on the lateral rail 6. When the flat light-load four-way shuttle vehicle walks on the transverse track 6, the second driving wheel set 231 of the second travelling mechanism 23 walks on the transverse track 6, and the guide wheel 212 rolls on the inner side of the transverse track 6, so that the flat light-load four-way shuttle vehicle and the transverse track 6 are ensured not to be in direct contact.
