Description

Technical Field

[0001] The utility model belongs to the technical field of shuttle vehicles for warehousing and logistics, and in particular relates to a pallet fixing device for the shuttle vehicle. Background Art

[0002] The shuttle-type storage system combines traditional shelves with high-precision guide rails, allowing shuttles to run smoothly on the rails. The rails simultaneously handle both cargo transportation and storage, greatly improving the utilization of storage space. The shuttles on the rails are characterized by high-speed operation, smooth movement, and precise positioning. A representative example is a shuttle-type shuttle. The shuttle shuttle shuttle shuttles through the aisles to store and retrieve goods, and the shuttle shuttle shuttle automatically changes aisles with the shuttle shuttle shuttle, effectively improving operational efficiency. When transporting goods, existing shuttle shuttles must travel to the bottom of the shelf's matching pallet, then use their load tray to lift the pallet and the goods on it. After that, the goods can be transported to the braking position according to instructions. However, existing shuttle shuttles are unable to clamp and secure the pallet, relying solely on the friction between the load tray and the pallet to limit its position. This can cause the pallet to slide, shift, or even fall during movement or deceleration, resulting in poor stability and a safety hazard. Utility Model Content
