Figure 1 As shown in FIG. 1 , in one embodiment, the transverse movement device for the three-dimensional storage system includes a lifting platform 1, a transverse movement trolley 2 and a transverse movement driving mechanism. The transverse movement trolley 2 can move along a first horizontal direction relative to the lifting platform 1, and the transverse movement trolley 2 includes a hanging plate 201 (see FIG. 1 ). Figure 2 ), the hanging plate 201 is provided with a slot 210 with an opening at the bottom. The transverse driving mechanism is installed on the lifting platform 1, and the transverse driving mechanism includes a chain sprocket mechanism arranged along the first horizontal direction, and the chain sprocket mechanism includes a transverse chain 108 that can be driven in two directions, and a transverse block 109 is fixed on the transverse chain 108 (see Figure 2 ), the transverse stopper 109 is used to follow the transverse chain 108 and form a working state of being engaged with the card slot 210 and a non-working state of being disengaged from the card slot 210 during the movement. Figure 3 As shown, before the traverse trolley 2 enters the warehouse, the traverse block 109 is located on the right side of the lifting platform 1. As the traverse chain 108 rotates counterclockwise, the traverse block 109 gradually gets stuck in the slot 210. Figure 4 As shown, when the transverse stopper 109 moves to the horizontal state, it moves the transverse trolley 2 to the left by a preset distance to Figure 5 The lateral movement block 109 is gradually disengaged from the card slot 210 until the lateral movement baffle does not block the card slot 210, indicating that the lateral movement trolley 2 is in place.
