Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a stereoscopic warehouse shuttle vehicle which is easy to turn. Background Art

[0002] The high-bay warehouse has high space utilization and high degree of automation, which can improve work efficiency and save space. The shuttle vehicle can efficiently and quickly store and retrieve goods in the high-bay warehouse.

[0003] Chinese patent CN216944663U discloses a bidirectional shuttle structure, which controls the relative movement of a slider by driving a first screw and a second screw to rotate through a dual-axis motor. The slider drives an extrusion plate to clamp a pallet loaded with goods to ensure the stability of the pallet during transportation.

[0004] However, when the above-mentioned two-way shuttle structure is used to transport larger pallets, the pallets cannot be clamped by the extrusion plates and placed above the flat extrusion plates. During transportation, the extrusion plates are higher than the moving plates, which may cause the lower end of the pallet to be unstable and cause the goods to fall or shift during transportation.

[0005] Based on this, the utility model designs a stereoscopic warehouse shuttle vehicle which is easy to turn to solve the above problems. Utility Model Content
