[0056] Among them, when the second detection member 250 is located at the detection position, the second detection member 250 is arranged toward the active detection area of ​​the pipe to be tested 400 located at the detection station. When the second detection member 250 is located at the avoidance position, the second detection member 250 can avoid the loading and unloading actions of the pipe to be tested 400 at the detection station.

[0057] The types of the first detection device and the second detection device 250 mentioned above include but are not limited to image detectors, X-ray detectors, ultrasonic detectors, etc.

[0058] Compared with the prior art, the pipe inspection device disclosed in the present invention inspects different circumferential positions of the pipe 400 to be inspected through the fixed inspection mechanism 100 and the movable inspection mechanism 200, and the second inspection member 250 moves between the inspection position and the avoidance position so that the second inspection member 250 does not affect the loading and unloading of the pipe 400 to be inspected at the inspection station while meeting the inspection requirements. The pipe inspection device disclosed in the present invention can realize accurate inspection of the circumference of the hot-expanded pipe.

[0059] In a specific embodiment disclosed in the present invention, the moving assembly includes a flip limiter 220 and a flip member 230, wherein the flip limiter 220 is provided with a first limiter portion and a second limiter portion 222; the flip member 230 is rotatably provided on the flip limiter 220 through a rotating shaft, and the second detection member 250 is provided on the flip member 230 to move between the detection position and the avoidance position with the flip member 230. When the flip member 230 flips to the first position, the flip member 230 abuts against the first limiter portion, and the second detection member 250 is located at the detection position; when the flip member 230 flips to the second position, the flip member 230 abuts against the second limiter portion 222, and the second detection member 250 is located at the avoidance position.

[0060] In order to ensure the stability of the position of the second detection member 250 during the detection process, a threaded connection hole 221 is opened on the first limiting portion, and a flip locking member 231 is arranged on the flip member 230. When the flip member 230 flips to the first position, the flip member 230 abuts against the first limiting portion, and the flip locking member 231 is threadedly connected to the threaded connection hole 221, and the flip limiting member 220 and the flip member 230 are fixed, thereby preventing the second detection member 250 from moving during the detection process.

[0061] Specifically, combined Figure 7 and Figure 8 The flip limit member 220 is provided with a flip limit groove. The flip member 230 is hinged to the two side walls of the flip limit groove through a flip axis and can rotate in the flip limit groove. At the same time, the bottom surface of the flip limit groove serves as a first limiting portion, which can fit and limit the flip member 230. The threaded connection hole 221 is opened through the bottom surface of the flip limit groove.

[0062] In addition, in order to facilitate operation, combined Fig. 9 and Fig.10 A flip handle 240 is provided on the flip member 230 , and the flip handle 240 can be held by an operator to drive the flip member 230 to flip.

[0063] The flipping angle of the flipping member 230 is not limited to 90°, and a slope for the flipping member 230 to lean against can be provided on the second limiting portion 222, so that the flipping member 230 can be reliably docked when the second detection member 250 is located at the avoidance position.

[0064] In another embodiment, the moving assembly includes a sliding stopper and a sliding member, the sliding stopper is provided with a slide rail, a third stopper and a fourth stopper, and the third stopper and the fourth stopper are respectively provided at both ends of the slide rail; the sliding member is slidably provided on the sliding stopper through the slide rail, and the second detection member 250 is provided on the sliding member to slide along the guide rail with the sliding member; when the sliding member slides to the third position along the slide rail, the sliding member abuts against the third stopper, and the second detection member 250 is located at the detection position, and when the sliding member slides to the fourth position along the slide rail, the sliding member abuts against the fourth stopper, and the second detection member 250 is located at the avoidance position. In this embodiment, the second detection member 250 moves between the detection position and the avoidance position by the sliding member sliding along the slide rail. Compared with the flipping technical solution of the second detection member 250 in the aforementioned embodiment, the translation technical solution of the second detection member 250 occupies a relatively larger space.

[0065] The third limiting portion and the fourth limiting portion may be limiting block structures.

[0066] Those skilled in the art can understand that, when there are multiple activity detection mechanisms 200, the structures of different activity detection mechanisms 200 can be the same or different.

[0067] In a specific embodiment disclosed in the present invention, the fixing assembly includes a bottom positioning block 120 and a bottom reference member 121 disposed on the bottom positioning block 120, and the pipe fitting 400 to be tested is positioned at the inspection station by the bottom reference member 121; the first inspection member includes a bottom inspection member disposed on the bottom positioning block 120, and the bottom inspection member is used to inspect the fixed inspection area of ​​the pipe fitting 400 to be tested located at the inspection station.

[0068] In a further optimized solution, the fixing assembly further includes a side positioning block 122 and a side reference member 123 disposed on the side positioning block 122, the first detection member further includes a side detection member disposed on the side positioning block 122, and the bottom detection member and the side detection member are used to detect the first area and the second area of ​​the fixed detection area of ​​the pipe 400 to be tested located at the detection station, respectively. The side reference member 123 moves between the reference position and the offset position by adjusting the assembly, and when the side reference member 123 is located at the reference position, the side reference member 123 is used to position the pipe 400 to be tested located at the detection station, and when the side reference member 123 is located at the offset position, the side reference member 123 avoids the arrangement of the pipe 400 to be tested located at the detection station, and does not serve as a positioning reference.

[0069] There are at least two bottom reference pieces 121 and side reference pieces 123 to respectively reliably position the bottom and side surfaces of the pipe 400 to be tested at the testing station. In particular, when there are not enough reference holes in the pipe 400 to be tested for hot air expansion, the pipe 400 to be tested can be positioned against the bottom reference piece 121 and the side reference piece 123 before testing.

[0070] In one embodiment, in combination Figure 4-Figure 6 The adjustment assembly includes a pin sleeve 131, an elastic member 132 and a limit pin 130. The pin sleeve 131 is arranged on the side positioning block 122, and the first end of the pin sleeve 131 is provided with a first positioning groove and a second positioning groove arranged at an angle, and the groove depth of the first positioning groove is less than the groove depth of the second positioning groove; the elastic member 132 is sleeved on the side reference member 123, and the two ends are respectively abutted against the operating part of the side reference member 123 and the second end of the pin sleeve 131; the limit pin 130 is penetrated through the positioning end of the side reference member 123; when the side reference member 123 is located at the reference position, the positioning end of the side reference member 123 passes through the pin sleeve 131 and is used to position the pipe 400 to be tested at the detection station, and the limit pin 130 is embedded in the first positioning groove; when the side reference member 123 is located at the offset position, the positioning end of the side reference member 123 is located in the pin sleeve 131, and the limit pin 130 is embedded in the second positioning groove. Due to the difference in depth between the first positioning groove and the second positioning groove, the limiting pin 130 can position the side reference member 123 at the reference position and the offset position respectively.

[0071] The side reference member 123 is designed to be a retractable structure by adjusting the assembly so that it can be used as needed. Figure 6 The included angle between the first positioning groove and the second positioning groove is usually 90°. The main body of the side reference member 123 is arranged vertically to the operating part so that the side reference member 123 is T-shaped as a whole. The operator can rotate the side reference member 123 through the operating part to move the side reference member 123 between the reference position and the offset position.

[0072] Combination Figure 1 and Figure 2In a specific embodiment disclosed in the present invention, there are two movable detection mechanisms 200, and the two movable detection mechanisms 200 are defined as a top detection mechanism and a side detection mechanism, respectively. The movable detection area includes a third area and a fourth area for the top detection mechanism and the side detection mechanism to perform detection, respectively; when the second detection member 250 of the top detection mechanism is located at the detection position, the second detection member 250 of the top detection mechanism is opposite to the above-mentioned bottom detection member and is arranged toward the detection station to detect the pipe 400 to be detected at the detection station; when the second detection member 250 of the top detection mechanism is located at the avoidance position, the second detection member 250 of the top detection mechanism is arranged to avoid the bottom detection member; when the second detection member 250 of the side detection mechanism is located at the detection position, the second detection member 250 of the side detection mechanism is opposite to the side detection member and is arranged toward the detection station to detect the pipe 400 to be detected at the detection station; when the second detection member 250 of the side detection mechanism is located at the avoidance position, the second detection member 250 of the side detection mechanism is arranged to avoid the side detection member. That is, the top side and bottom side of the pipe 400 to be tested are tested by the second detection member 250 and the bottom detection member of the top detection mechanism, and the left and right sides of the pipe 400 to be tested are tested by the second detection member 250 and the side detection member of the side detection mechanism.

[0073] The present invention divides the circumferential area of ​​the pipe 400 to be tested, and which areas are to be tested by the fixed testing mechanism 100 and which areas are to be tested by the movable testing mechanism 200 according to actual needs. The circumferential area of ​​the pipe 400 to be tested is not limited to being divided into the four parts in the above embodiment. In addition, the avoidance action of the movable testing mechanism 200 to the testing station can make the pipe 400 to be tested located at the testing station have a larger loading and adjustment space when only the fixed testing mechanism 100 is used to test the pipe 400 to be tested, thereby better meeting the testing requirements of the large circumference of the pipe 400 to be tested.

[0074] Further optimization scheme, in order to reliably fix the pipe 400 to be tested on the testing station during the testing process, a clamping member 112 is provided on the fixing assembly for clamping the pipe 400 to be tested on the testing station. Exemplarily, the clamping member 112 can be a chuck. The number of clamping members 112 can be arranged and selected according to the actual situation of the pipe 400 to be tested.
