Description

Technical Field

[0001] This utility model relates to the field of AGV handling technology, specifically to an anti-collision device for AGV unmanned transport vehicles. Background Technology

[0002] AGVs (Automated Guided Vehicles) have wide applications in various fields. In industrial manufacturing, they can reliably transport large steel components or precision parts, reducing human error and improving production efficiency. In warehousing and logistics, they are responsible for moving goods to and from shelves, optimizing warehouse space utilization, and improving logistics efficiency.

[0003] Currently, the anti-collision devices for AGV (Automated Guided Vehicle) unmanned transport vehicles (AGVs) consist of anti-collision plates installed at both ends of the vehicle. For example, patent CN218663845U discloses an anti-collision AGV vehicle that uses springs to generate cushioning and prevent damage to the vehicle; this is a protective device only for AGV vehicles. However, during cargo handling, the dimensions of the transported goods are sometimes much larger than the AGV itself, especially when the goods extend beyond the left and right ends of the AGV. In such cases, existing anti-collision plates are ineffective. During transport, the ends of the goods may encounter obstacles, and after a collision, the goods can easily fall off or even be damaged. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing an anti-collision device for AGV (Automated Guided Vehicle). The protective frame can surround the goods, not only positioning them to ensure safety during transportation, but also preventing them from colliding with obstacles before the goods and AGV itself. The buffer ball mitigates the impact force on the goods and AGV, thus providing protection and achieving dual protection for both the goods and the AGV.

[0005] To achieve the above objectives, this utility model provides the following technical solution:
