[0002] Steel pipes are not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers. They are also an economical steel material. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and realize factory-based mechanized construction. The last step in steel pipe processing is packaging. After packaging, the steel pipe is more convenient for lifting and transportation. At present, steel pipe packaging has been mechanized to a certain extent, which greatly reduces labor intensity and gradually replaces manual stacking and packaging. The seamless steel pipe packaging production line is an equipment system for automated production and packaging of seamless steel pipes. The production line usually includes multiple workstations to complete a series of production processes from raw material feeding, processing, testing to packaging. The seamless steel pipe packaging production line can improve production efficiency, reduce labor costs, and ensure the stability of product quality.

[0003] However, the existing seamless steel pipe packaging production lines often only have the function of packaging steel pipes, and are unable to perform lifting operations on the packaged steel pipes, resulting in the need for manual transportation of these packaged steel pipes to vehicles or shelves, which not only wastes manpower but also affects the packaging efficiency of steel pipes.

The motor provides power to drive the rotation of the sprocket, so that the entire lifting device can operate automatically, improve work efficiency and reduce labor costs. Through the design of connectors and connecting rods, the synchronous rotation of the sprockets is guaranteed to ensure the stability of the lifting plate, effectively avoiding problems caused by movement at different speeds or in different directions. The lifting plate, as a platform for carrying seamless steel pipes, can be easily loaded and unloaded through lifting operations, improving production efficiency and operational convenience. The setting of counterweights can balance the weight of the lifting plate, ensure smooth and reliable lifting operations, and avoid instability caused by uneven weight. The design of the slide bar can keep the lifting plate stable during the up and down movement, avoid shaking and tilting, and ensure the safety and stability of the seamless steel pipe packaging stack transportation process. The lifting device can efficiently and stably complete the transportation task of seamless steel pipe packaging stacks without the need for manpower for handling, saving manpower while also improving production efficiency and operational safety.

[0016] 2. Through the setting of the slide groove and the slider, a stable track is provided, so that the counterweight can slide along the slide groove during the lifting process. This design effectively reduces the friction resistance of the counterweight during movement and ensures the smooth movement of the counterweight. The counterweight will not shake due to its own gravity during the lifting or lowering of the lifting chain, which effectively improves the stability of the lifting device, avoids the instability caused by the shaking of the counterweight, ensures the stable movement of the counterweight, and can also effectively protect the counterweight from external interference or accidental collision. This protection device can extend the service life of the counterweight and reduce maintenance costs. The counterweight can move smoothly under the guidance of the slide groove and the slider, which improves the safety of the operation process. The operator can perform lifting operations more confidently, reduce accidental risks, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
