Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figure 1 , Figure 2 As shown, the automatic adjustment device for X-ray inspection of spiral tubes in this embodiment includes an inspection carriage 1, a probe arm 7, a cantilever 11, a PLC controller 14, and a touch screen 15. The inspection carriage 1 is equipped with several conveying rollers 2 for supporting and conveying the spiral tubes. A rotating roller group is provided on one side of the conveying rollers 2. The rotating roller group includes two rotating rollers 3 connected by a rotating roller screw. The rotating roller screw can adjust the distance between the two rotating rollers 3 to accommodate spiral tubes of different diameters. A first stepper motor 4 and a first encoder 5 are provided on one side of the rotating roller group. The first stepper motor 4 and the first encoder 5 are connected to the rotating roller screw. By controlling the rotation of the first stepper motor 4, the distance between the rotating rollers 3 can be precisely adjusted, and the first encoder 5 can detect the position of the rotating rollers 3 in real time.

[0018] The probe arm 7 is mounted on the probe arm bracket 6. The probe arm 7 adopts a chain-type lifting mechanism and is equipped with a second stepper motor 8 and a second encoder 9. Its lifting height is controlled by the second stepper motor 8 and the second encoder 9. The cantilever arm 11 is mounted on the cantilever bracket 10. The cantilever arm 11 adopts a chain-type lifting mechanism and is equipped with a third stepper motor 12 and a third encoder 13. Its lifting height is controlled by the third stepper motor 12 and the third encoder 13. At this time, the lifting height of the probe arm 7 and the cantilever arm 11 can be adjusted according to the length of the spiral tube and the detection requirements. The probe arm bracket 6 and the cantilever bracket 10 are respectively set on the same side of the detection carriage 1.

[0019] like Figure 2 As shown, the PLC controller 14 is electrically connected to the first stepper motor 4, the second stepper motor 8, the third stepper motor 12, the first encoder 5, the second encoder 9, the third encoder 13, and the touch screen 15. The PLC controller 14 is responsible for receiving instructions from the touch screen 15 and controlling the operation of each stepper motor and encoder. The touch screen 15 provides a human-machine interface, and operators can input detection parameters and view detection results through the touch screen.

[0020] Among them, several conveying rollers 2 are arranged sequentially along the inlet pipe direction, and several conveying rollers 2 are arranged parallel to each other, such as Figure 1 As shown, the arrow indicates the direction of the inlet pipe, and the arrangement of several conveying rollers 2 is perpendicular to the direction of the inlet pipe.

[0021] Specifically, rotating roller groups are respectively provided on the inward side of the first and last conveying rollers along the inlet pipe direction, and several conveying rollers 2 are also provided between the first and last conveying rollers.

[0022] In this embodiment, the automatic adjustment device for X-ray inspection of spiral tubes is connected to the touch screen 15 via software. The first encoder 5, the second encoder 9, and the third encoder 13 respectively transmit the current positions of the rotating rollers 3, the probe arm 7, and the cantilever 11 to the PLC controller 14. During normal use, when a steel pipe needs to be inspected, the touch screen 15 displays the specifications of the steel pipe after it enters the operating table. After the steel pipe information is input, the PLC controller 14 calculates and outputs corresponding instructions based on the input diameter information, and simultaneously controls the first stepper motor 4 and the second stepper motor. Stepper 8 and the third stepper motor 12 are activated. Stepper 8 rotates the rotary roller screw according to the control signal, thereby adjusting the distance between the two rotary rollers to match the diameter of the spiral tube. Stepper 8 and the third stepper motor 12 drive the chain-type lifting structure of probe arm 7 and cantilever 11 respectively according to the control signal, thereby adjusting the lifting height of probe arm 7 and cantilever 11. The corresponding encoders provide real-time feedback of the current position data. When the required detection position is reached, the system automatically stops. Conveying roller 2 transports the steel pipe to be detected to the detection position along the pipe inlet direction. The lead door closes and the detection begins.

[0023] This utility model discloses an automatic adjustment device for X-ray inspection of spiral tubes. It can automatically adjust according to spiral tubes of different diameters and lengths, and is suitable for X-ray inspection of spiral tubes of various specifications and models. At the same time, through the precise control of PLC controller and encoder, it can realize the precise adjustment of the distance between rotating rollers and the lifting height of probe arm and cantilever arm, which improves the accuracy and reliability of inspection. Operators only need to input the inspection parameters through the touch screen to realize the automatic adjustment of the entire inspection process, which greatly improves the inspection efficiency and automation level.

[0024] This utility model discloses an automatic adjustment device for X-ray inspection of spiral pipes. By setting up an inspection trolley, probe arm, cantilever, PLC controller and touch screen, it eliminates the need for manual adjustment when inspecting spiral welded steel pipes with X-rays. It can automatically adjust the corresponding positions of the probe arm, rotating roller and plate according to the corresponding specifications of the steel pipe.
