Description

Technical Field

[0001] The invention relates to the technical field of logistics warehousing and handling, and in particular to a backpack-type four-way shuttle vehicle. Background Art

[0002] The backpack four-way shuttle is a modern warehousing and logistics equipment, widely used in automated warehouses and material handling systems. Its main features and advantages include:

[0003] 1. Four-way mobility

[0004] Flexibility: The equipment can move in multiple directions (front, back, left, right), and can be flexibly operated in a limited space, improving space utilization. Fast positioning: The four-way shuttle can quickly adjust its position, effectively reducing material handling time and improving overall work efficiency.

[0005] 2. Efficient handling

[0006] Back-loading design: The backpack design allows the shuttle to carry heavier items, which is suitable for the handling needs of various goods and increases its applicability. Strong load capacity: It usually has a large load capacity and is suitable for handling bulk materials in industrial and warehousing environments.

[0007] The existing backpack four-way shuttle can move in multiple directions, front, back, left, and right. However, it is not convenient to move vertically when transporting goods on multi-layer shelves, resulting in low space utilization efficiency, inability to fully utilize the vertical space of the warehouse, and limiting storage capacity. It needs to rely on other equipment (such as elevators), which increases the handling time and the complexity of the workflow. Reliance on other equipment may increase operating costs and management difficulties.

[0008] In summary, the prior art lacks a transport technology for the backpack four-way shuttle vehicle that moves vertically up and down. Summary of the invention

By setting up the carrying limit frame, under the action of the adjustment mechanism, the two carrying limit frames will be driven to rotate, which can limit the carrying goods to prevent them from sliding or falling during transportation or storage, reduce the risk of damage, and can be adjusted according to goods of different sizes and shapes, flexibly respond to various goods needs, and effectively improve the safety and efficiency of goods management;

[0022] 3. By setting a transmission rod, when the lifting frame moves down, the transmission rod will be driven to rotate through the transmission teeth, so that the transmission rod can drive the rotating seat to rotate, so that the wheels on the rotating seat can change direction. There is no need to set up multiple sets of wheels to achieve multi-directional movement, which reduces costs, effectively improves the flexibility and multi-directional movement ability of the vehicle body, and is suitable for a variety of application scenarios.
