[0021] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example: Refer to Figure 1-3A surface quality inspection device for stainless steel pipes includes a base 1. A first electric slide rail 2 is mounted on the upper wall of the base 1. A mounting frame 3 is mounted on the moving end of the first electric slide rail 2. An ultrasonic flaw detector body 4 is mounted on the front wall of the crossbeam of the mounting frame 3. A mounting column 5 is mounted on the lower wall of the crossbeam of the mounting frame 3. An electric push rod 6 is embedded in the mounting column 5. An extension column 7 is mounted on the telescopic end of the electric push rod 6. A clamping frame 8 is mounted on the lower end of the extension column 7. An ultrasonic flaw detector head body 9 is clamped on the clamping frame 8. A wire 10 connects the ultrasonic flaw detector head body 9 and the ultrasonic flaw detector body 4. A load-bearing drive structure is mounted on the base 1 and located in front of the first electric slide rail 2. The load-bearing drive structure includes four second electric slide rails 11, four support rods 12, four support wheels 13, and a drive unit. The four second electric slide rails 11 are mounted on the base 1 and located in front of the first electric slide rail 2. Each support rod 12 is mounted on the moving end of each second electric slide rail 11, each support wheel 13 is mounted on each support rod 12, and the drive unit is mounted on the base 1 and located between the four second electric slide rails 11. The drive unit includes two mounting columns 14, two electric cylinders 15, two top columns 16, two servo motors 17, and two drive wheels 18. The two mounting columns 14 are mounted on the base 1 and located between the four second electric slide rails 11. The two electric cylinders 15 are embedded in the two mounting columns 14. The two top columns 16 are mounted on the telescopic ends of the two electric cylinders 15. Each servo motor 17 is embedded in each top column 16, and each drive wheel 18 is mounted on the driving end of each servo motor 17. Each drive wheel 18 is respectively equipped with a rubber layer 19. Four pads 20 are mounted on the lower wall of the base 1. A co-positioning rod 21 is mounted between the two top columns 16.

[0023] The specific working principle is as follows:

[0024] Workers operate the system via a programmable controller installed on it, adjusting the system according to the actual diameter of the steel pipe being inspected. The moving end of the second electric slide rail 11, mounted on the base 1, moves to both sides to adjust the support for the steel pipe diameter. After adjustment, the moving end of the second electric slide rail 11 stops moving. Workers place the steel pipe to be inspected onto the support wheels 13 mounted on the support rod 12. The four support wheels 13 support the steel pipe. After support is complete, the electric cylinder 15 inside the assembly column 14 mounted on the base 1 pushes the top column 16 mounted on its telescopic end to rise. This causes the drive wheel 18 on the drive end of the servo motor 17 mounted inside the top column 16 to contact the lower wall of the steel pipe via the rubber layer 19 mounted on it. The electric cylinder 15 then stops telescopically. The positioning rod 21 is used to raise or lower the two top columns 16 simultaneously. After the rubber layer 19 contacts the lower wall of the steel pipe, the servo motor 17 drives the... As wheel 18 rotates, the rubber layer 19 on the drive wheel 18 contacts the lower wall of the steel pipe, causing the steel pipe to roll on the support wheel 13. Simultaneously, the electric push rod 6 inside the mounting column 5 on the mounting frame 3 pushes the extension column 7 down, causing the ultrasonic flaw detector head body 9 mounted on the mounting bracket 8 of the extension column 7 to contact the rotating steel pipe for flaw detection. The data is displayed on the display screen on the ultrasonic flaw detector body 4 via the wire 10, allowing the staff to observe the data on the ultrasonic flaw detector body 4 in real time. During flaw detection, the moving end of the first electric slide rail 2 mounted on the base 1 begins to move slowly, thereby driving the installation to move laterally, facilitating length flaw detection of the steel pipe. The pad 20 is used for auxiliary support to prevent the device from tilting due to uneven ground. After the inspection is completed, the electric push rod 6 and the electric cylinder 15 reset, the servo motor 17 stops running, and the staff can then remove the inspected stainless steel pipe.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
