In the production process of pipes, quenching is a key process used to improve the hardness and strength of pipes. However, the handling and stacking of pipes before and after quenching often requires a lot of manpower and time. The traditional manual handling method is not only inefficient, but also has a high safety risk. Therefore, it has become an urgent need in the industry to design a lifting equipment that can be operated automatically to improve production efficiency and safety.

[0026] As a preferred solution, further, the lifting claw 37 can be lifted and moved independently, and keep corresponding to each other up and down, which can be used for clamping or expanding the inner wall according to design requirements, and can also be used for lifting.

[0027] As a preferred solution, further, the lifting frame 33 can be moved to the right side of the main frame 10 through the moving seat 31, and the lifting frame 33 can be rotated 360 degrees to change the direction according to design requirements and usage.

[0028] As a preferred solution, further, the main structure 1 can be docked by clamping the first adapter arm 15 in the second fitting groove 5, and fixedly connected by the adapter bolt 17, so as to be used for stably carrying a large number or heavier pipes after the two sets of equipment are docked and fixed.

[0029] Working principle: The main frame 10 is supported at a certain height by the support arm 11 in the main structure 1, and better weighing force and stability are achieved by the tilt setting of the support arm 11; the equipment can be moved by the universal wheel 12 to improve the flexibility of the equipment; When using equipment to lift pipes: if the pipe diameter is small, its relative weight is light; Therefore, the first motor 23 in the first hoisting structure 2 can be controlled to drive the gear 24, and the tooth arm 22 can be moved by the engagement transmission of the gear 24 and the tooth arm 22 with the help of the limit seat 21, so that the railing 25 can be driven to rise to a certain height; at this time, the pipe can be placed at the angle formed between the railing 25 and the tooth arm 22, so that the pipe can be stably driven to rise without clamping; because the first hoisting structure 2 is symmetrically arranged on the support arm 11 on one side of the main frame 10, the pipe can be lifted to different heights by two groups of first hoisting structures 2 for use together, and multiple pipes can also be lifted together for use; When using equipment to lift pipes: if the pipe has a larger diameter, its relative weight will be heavier; At this time, the second motor 35 in the lifting frame 33 of the second lifting structure 3 can be controlled to drive the screw rod 36 to rotate, and the lifting claws 37 located in the upper and lower staggered corresponding positions can be adjusted to move up and down; When one of the lifting claws 37 moves to the bottom of the lifting frame 33, it can be inserted into the pipe, and then the other lifting claw 37 is controlled to be located above the outside of the pipe, so that the pipe can be clamped and fixed by the lifting claws 37. After clamping, the lifting claws 37 are synchronously controlled to rise to a certain height. The two lifting claws 37 can also be inserted into the pipe, and then the lifting claws 37 are controlled to be relatively separated to expand and fit on the inner wall of the pipe for fixing, and the lifting claws 37 are synchronously driven to rise to drive the pipe to lift. When the second hoisting structure 3 is in use, the direction of the lifting claw 37 can be adjusted by rotating the shaft 34 in the bearing 38 according to the use requirements, that is, the direction of lifting the pipe can be adjusted; the electric slide rail 14 can also be driven to drive the moving seat 31 to move left and right, and the lifting position of the lifting frame 33 can be adjusted to be located below the middle of the main frame 10 or on the right side of the main frame 10; when the moving seat 31 moves to the right, the moving seat 31 will move in the slideway 13 with the help of the limiting arm 32 and assist the force; During the use of the first hoisting structure 2 and the second hoisting structure 3, the main structure 1 can be docked and matched to achieve the coordinated use of multiple sets of the first hoisting structure 2 and the second hoisting structure 3; For example, two devices are relatively transferred through the first transfer arm 15, that is, the first transfer arm 15 in the first fitting groove 4 is moved out, and one end of the first transfer arm 15 is inserted into the second fitting groove 5 and locked with the relative communication part of the first fitting groove 4. At this time, the first transfer arm 15 cannot rotate, and then the other end of the relatively staggered first transfer arm 15 can be relatively fitted and docked, and both ends of the first transfer arm 15 are connected and fixed by the transfer bolt 17, and the connection end of the first transfer arm 15 is connected by inserting a pair of locking rods 18 to apply force and limit the position to complete the connection; Between the main structures 1, after the first transfer arm 15 is inserted into the second fitting groove 5, the second transfer arm 16 is taken out from the third fitting groove 6, and then the second transfer arm 16 is installed between the first transfer arms 15 to increase the spacing of the main structures 1 for use; After the main structures 1 are relatively connected in series, longer pipes can be carried by the first lifting structure 2 on the main structure 1, which also makes the equipment more stable when carrying and lifting. Moreover, with the help of the second lifting structure 3, larger diameter pipes of corresponding lengths can be lifted after being rotated relative to each other, and the two ends can be clamped or expanded and fixed before lifting.

[0030] In summary, this technical solution is designed for the palletizing and quenching process of stainless steel pipes, providing an efficient and safe automated lifting solution: 1. Adapt to stainless steel pipes of different specifications: In the production and processing of stainless steel pipes, pipes of different diameters and lengths are often involved; the hoist can handle small-diameter, light-weight pipes and large-diameter, heavy-weight pipes respectively through the flexible combination of two hoisting structures (the first hoisting structure 2 and the second hoisting structure 3). This versatility ensures that the equipment can be applied to stainless steel pipes of various specifications.

[0031] 2. Improve palletizing efficiency: The handling and palletizing of stainless steel pipes before and after quenching is a time-consuming process; the automated operation characteristics of the equipment can quickly and accurately lift the pipes to the designated location, significantly reducing manual operation time and improving palletizing efficiency; at the same time, the modular design allows multiple devices to work together, further improving overall operating efficiency.

[0032] 3. Safe and stable lifting process: During the quenching process, stainless steel pipes need to undergo high-temperature treatment, and the safe handling of pipes is particularly important. The equipment ensures the stability of pipes during the lifting process through the clamping and expansion design of the lifting claws 37 to avoid safety hazards caused by slipping or collision. The automated operation reduces manual intervention and reduces the operating risks in high-temperature environments.

[0033] 4. Flexible process adaptability: The quenching process may require the pipe to be processed in different positions and directions; through the 360-degree rotation and left and right movement functions of the lifting frame 33, the equipment can flexibly adjust the lifting position and direction according to the process requirements to ensure the best processing state of the pipe during the quenching process.

[0034] 5. Convenience of equipment movement and adjustment: With the help of universal wheels 12 and electric slide rails 14, the equipment can be flexibly moved in the production workshop and quickly adapted to the needs of different work areas; this convenience allows the equipment to be easily integrated into the existing production process without the need for large-scale site adjustments or additional infrastructure investment.

[0035] In summary, the automatic lifting sling for palletizing and quenching of stainless steel pipes is perfectly suitable for the palletizing and quenching process of stainless steel pipes through its versatility, safety, automation and flexibility. It can significantly improve production efficiency and safety and meet the needs of modern industry for efficient automation equipment.
