Description
Technical Field
[0001] This utility model relates to the technical field of steel pipe processing equipment, and more specifically, to a drying device for steel pipe processing. Background Technology
[0002] Steel pipes are steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. Using steel pipes to manufacture highway bridges not only saves steel, but also, during the processing of steel pipes, some liquid will adhere to their outer surface after surface treatment and cleaning, which needs to be dried.
[0003] In the existing technology, when drying steel pipes, the steel pipes are generally moved by a conveyor device, and hot air is used to dry the inner and outer surfaces of the steel pipes. However, there are some problems in its use. When moving the steel pipes, they are generally placed directly on the conveyor chain. When the conveyor chain is subjected to gravity, it will bounce up and down, making it inconvenient to position the steel pipes and making it impossible to accurately dry the inside of the steel pipes.

[0021] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0022] This utility model provides, for example Figure 1-3The drying device shown includes a worktable 1, with drive sprockets 2 at the four corners of the worktable 1. Two drive sprockets 2 on the same side are connected by a drive shaft 3, and rolling bearings 4 are mounted at both ends of the drive shaft 3. The rolling bearings 4 are mounted on the worktable 1 via connecting rods 5. Two drive sprockets 2 on the same end are connected by a drive chain 6. A servo motor 7 is mounted on the worktable 1 and connected to one of the drive sprockets 2. The worktable 1 has a holding mechanism and a drying mechanism. The holding mechanism includes multiple arc-shaped support rods 8 mounted on the drive chain 6. The steel pipe is placed on the arc-shaped support rod 8, and a support frame 9 is installed at the lower end of the arc-shaped support rod 8. The lower end of the support frame 9 is placed on the workbench 1. The drying mechanism includes a first air pipe 10 installed on both sides of the upper end of the workbench 1. The lower end of the first air pipe 10 has multiple first air outlets 11. The steel pipe can pass under the first air pipe 10. A second air pipe 12 is installed on both sides of the upper end of the workbench 1. The upper end of the second air pipe 12 has multiple second air outlets 13. The steel pipe can pass over the second air pipe 12. A third air pipe 14 is installed on both sides of the upper end of the workbench 1. The third air pipe 14 can blow air from one side of the steel pipe.
[0023] The drying process of this device for steel pipes is as follows: The cleaned steel pipe is placed on the arc-shaped support rod 8 using mechanical equipment. The servo motor 7 is started, driving the transmission sprocket 2. Through the connection between the transmission shaft 3 and the transmission chain 6, the transmission sprocket 2 drives the transmission chain 6. The transmission chain 6 moves the steel pipe via the arc-shaped support rod 8. The support frame 9 supports the arc-shaped support rod 8 and the steel pipe. When the steel pipe moves to the lower end of the first air outlet 10, the servo motor 7 is turned off, and the upper end of the steel pipe can be dried through the first air outlet 11. After drying, the servo motor 7 is restarted. When the steel pipe moves above the second air pipe 12, the servo motor 7 is turned off. The lower end of the steel pipe can be dried through the second air outlet 13. Then the servo motor 7 is restarted. When the steel pipe moves to the side of the third air pipe 14, the servo motor 7 is turned off. The inside of the steel pipe can be dried through the third air pipe 14. Then the steel pipe is made to pass through the first air pipe 10, the second air pipe 12, and the third air pipe 14 and be dried again. After drying, the steel pipe can be removed by mechanical equipment.
[0024] Refer to the instruction manual appendix Figure 2 The support frame 9 includes movable rods 15 installed on both sides of the lower end of the arc-shaped support rod 8, support wheels 16 are installed on both sides of the lower end of the movable rods 15, support platforms 17 are installed on both sides of the upper end of the worktable 1, the lower ends of the support wheels 16 are placed on the support platforms 17, and the support platforms 17 have inclined surfaces at both ends.
[0025] The process of the support frame 9 supporting the arc-shaped support rod 8 is as follows: Under normal conditions, the support wheel 16 is located above the workbench 1. When the support wheel 16 moves to the support platform 17, the arc-shaped support rod 8 can be supported by the support wheel 16 and the moving rod 15. Then, the steel pipe is placed on the arc-shaped support rod 8 to prevent the steel pipe from falling.
[0026] Refer to the instruction manual appendix Figure 2 The arc-shaped support rod 8 includes a fixed rod 18 mounted on the transmission chain 6. The upper end of the fixed rod 18 has a connecting groove 19, and a lifting rod 20 is provided in the connecting groove 19. The lifting rod 20 and the inner surface of the connecting groove 19 are connected by a connecting spring 21. A U-shaped rod 22 is installed on the upper end of the lifting rod 20, and the fixed rod 18 is installed on the lower end of the lifting rod 20. Under normal conditions, the connecting spring 21 is in a stretched state. Under the tension of the connecting spring 21, the lifting rod 20 can be pulled downward. When the support wheel 16 moves to the support platform 17, the lifting rod 20 can be pushed upward. The support wheel 16 can reduce the friction when the arc-shaped support rod 8 moves, and the U-shaped rod 22 can prevent the steel pipe from falling to both sides.
[0027] Refer to the instruction manual appendix Figure 2 Included with instruction manual Figure 3 The support platform 17 on the workbench 1, away from the third blow pipe 14, has inclined grooves 23 at both ends. The support wheel 16 can move into the inclined groove 23. An intercepting plate 24 is installed on the workbench 1 on one side of the inclined groove 23. When the support wheel 16 moves to the inclined groove 32, the U-shaped rod 22 can move downward under the action of gravity and the tension of the connecting spring 21, but the U-shaped rod 22 on the other side will not move downward. This allows the steel pipe to be in an inclined state, which facilitates the discharge of liquid inside the steel pipe. The intercepting plate 24 can intercept the steel pipe and prevent it from sliding to one side.
[0028] Heating wires are installed in the first air pipe 10, the second air pipe 12, and the third air pipe 14 at the end of the workbench 1, while no heating wires are installed in the first air pipe 10, the second air pipe 12, and the third air pipe 14 at the front of the workbench 1. This allows the liquid on the steel pipe to be carried away by the airflow before heating the steel pipe, reducing the amount of liquid residue on the steel pipe. Then, the air in the first air pipe 10, the second air pipe 12, and the third air pipe 14 is heated by the heating wires, which saves energy.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
