It integrates advanced technologies such as the Internet of Things, big data, cloud computing, and artificial intelligence to achieve a high degree of automation, informatization, and intelligence in warehouse operations. In smart storage warehouses, automated equipment such as stackers, AGVs (automatic guided vehicles), and RGVs (rail-guided shuttles) work together to accurately and efficiently complete the processes of goods entering, storing, picking, packing, and leaving the warehouse, greatly improving the efficiency and accuracy of warehousing operations. At the same time, through the Internet of Things technology, various equipment, goods, and even environmental parameters in the warehouse can be interconnected, monitored, and scheduled in real time to ensure the safety and smoothness of warehouse operations. The smart warehousing system also has a strong data analysis capability, which can deeply mine and analyze the warehouse's inventory status, operating efficiency, cargo flow, and other data, providing a scientific basis for the company's inventory management, production planning, logistics distribution, etc., and helping the company achieve refined management and decision-making optimization. In addition, smart storage warehouses also focus on environmental protection and energy saving. Through intelligent scheduling and energy management systems, they effectively reduce the energy consumption and carbon emissions of warehouse operations, which is in line with the concept of sustainable development.

[0003] The warehouse stacker is the core equipment in the automated warehousing system, with high-precision and high-efficiency cargo storage and retrieval capabilities. It is controlled by a computer program and can flexibly shuttle between the shelves of the stereoscopic warehouse to accurately place or take out the goods at the designated location. The stacker has a compact structure and stable operation. It can greatly improve the storage density and operating efficiency of the warehouse, reduce labor costs, and reduce the risk of cargo damage. It is an indispensable part of modern intelligent warehousing. However, although the existing technology can realize the storage and retrieval of fork pallets, it is difficult to apply to the longitudinal storage of goods that are too long, and the storage and retrieval are inconvenient.

[0004] Therefore, it is necessary to provide a stacker push-pull device to solve the above-mentioned technical problems. Summary of the invention

The chain drive and the rolling structure of the grooved steel wheel 10 in the channel steel 14 ensure the smooth movement of the traction device 2, thereby ensuring the stability of the pallet 1 The pulling of the device can be applied to the traction of goods that are too long in the longitudinal direction, and can also be used in other traction occasions. When the goods are required to be too long in the longitudinal direction, it can be used for heavy-load pushing and pulling, and can also be used for light-load synchronous belt transmission occasions. It has a wide range of applications and strong practicality. When the precision requirement is too high, the guidance of the channel steel wheel 10 and the channel steel 14 can be changed to the guided traction of the linear guide slider. The warehouse in and out processing capacity is more flexible than before, and the workpiece that is too large or too long can be picked up and placed flexibly, and the space is fully utilized. The thin rubber sleeve is set to effectively increase the friction between the traction shaft 8 and the hook on the pallet 1, thereby improving the stability of the clamping.
