[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a high-temperature resistant thick-walled stainless steel pipe inspection device. The device comprises an inspection platform 1 with a limiting component 2 at its upper center. The limiting component 2 fixes the position of the steel pipe body 3 to be inspected, ensuring that the steel pipe body 3 does not shift during inspection, thereby improving the accuracy of the inspection. Simultaneously, an outer wall inspection mechanism 4 is provided. The first inspection component 41 of the outer wall inspection mechanism 4 is located on the upper and lower sides of the fixed steel pipe body 3, and can move left and right to comprehensively inspect the outer wall of the steel pipe body 3. Furthermore, an inner wall inspection mechanism 5 is provided on the left and right sides of the outer end of the steel pipe body 3. The second inspection component 51 of the inner wall inspection mechanism 5 can simultaneously enter the interior of the steel pipe body 3 from both sides, comprehensively inspecting the inner wall of the steel pipe body 3. This allows for simultaneous inspection of both the inner and outer walls of the steel pipe body 3, effectively improving inspection efficiency. Finally, a marking mechanism 6 is provided to mark the locations of detected defects in the steel pipe body 3, facilitating subsequent review by operators.

[0026] like Figures 1-4 As shown, a testing platform 1 is provided, and a limit component 2 is provided at the upper middle part of the platform. The limit component 2 includes a fixed block 21 fixedly installed at the upper middle part of the testing platform 1. Electric push rods 23 are symmetrically installed on the front and rear sides of the upper end of the fixed block 21. The two sets of electric push rods 23 are controlled by a synchronous controller and can run synchronously. A limit plate 22 is installed at the output end of the electric push rod 23, which can place the steel pipe body 3 to be tested at the upper middle part of the fixed block 21.

[0027] Then open the electric push rod 23. The output end of the electric push rod 23 can push the connected limiting plate 22 to move inward, so that its inner end can fit with the outer side of the middle part of the steel pipe body 3. This can limit the steel pipe body 3 to be tested, ensuring that the steel pipe body 3 will not shift its position during testing, thereby improving the accuracy of testing.

[0028] The outer wall inspection mechanism 4 is set on the upper and lower sides of the steel pipe body 3, and the inner wall inspection mechanism 5 is symmetrically set on the left and right ends of the steel pipe body 3. The outer wall inspection mechanism 4 and the inner wall inspection mechanism 5 are combined to form a comprehensive inspection mechanism.

[0029] The outer wall inspection mechanism 4 includes an inspection component 41 located on the upper and lower sides of the outer side of the steel pipe body 3. A long strip-shaped transverse groove is opened in the middle of the inspection table 1. The inspection component 41 is also located on the upper and lower sides of the transverse groove. An installation block 42 is fixedly installed on the outer side of the inspection component 41. A support frame 43 is fixedly connected to the outer side of the installation block 42. An electromagnetic slide rail 44 is slidably connected to the lower rear side of the support frame 43. The electromagnetic slide rail 44 is installed on the upper rear side of the inspection table 1.

[0030] Secondly, the inner wall detection mechanism 5 includes detection components 51 symmetrically arranged at both ends of the steel pipe body 3. The output end of the electric push rod 52 is fixedly connected to the outside of the detection component 51. The two sets of electric push rods 52 can be controlled by a synchronous controller and can run synchronously. The outer end of the electric push rod 52 is fixedly connected to the detection table 1.

[0031] After the steel pipe body 3 is fixed, the controller that controls the electromagnetic slide rail 44 can be activated first, which will cause the support frame 43 to move left and right inside the electromagnetic slide rail 44. The movement of the support frame 43 can drive the mounting block 42 and the detection component 41 installed on the front side to move synchronously. The detection component 41 is set on the upper and lower sides of the steel pipe body 3. At the same time, the probe of the upper detection component 41 is aligned with the upper side and the front and rear sides of the steel pipe body 3. That is, the movement of the detection component 41 can perform all-round detection on the outer wall of the steel pipe body 3.

[0032] In addition, after the detection component 41 has completed the detection of the outer wall of the steel pipe body 3, the electric push rod 52 is activated to push the connected detection component 51 to move inward. The detection component 51 can enter the interior of the steel pipe body 3 from both the left and right sides to detect the inner wall of the steel pipe body 3.

[0033] Detection Component 1 41 and Detection Component 2 51 integrate an ultrasonic thickness measuring probe, a phased array defect detection probe, and an eddy current probe, which can simultaneously measure the wall thickness, internal defects, and surface oxide layer thickness of the steel pipe. This can provide key data support for the remaining service life and safety performance of the steel pipe in a high-temperature environment.

[0034] Additionally, a marking mechanism 6 is provided on the rear side of the testing platform 1. The marking mechanism 6 includes a paint tank 64 located on the rear side of the middle part of the testing platform 1. The paint tank 64 is filled with paint. A pneumatic diaphragm pump 63 (model QBY3-40) is installed on the upper side of the middle part of the paint tank 64. A connecting pipe 62 is fixedly connected to the upper side of the middle part of the pneumatic diaphragm pump 63. A marking spray gun 61 is fixedly connected to the front side of the upper end of the connecting pipe 62.

[0035] Secondly, the marking spray gun 61 is installed inside the upper side of the mounting block 42, with its spray nozzle aligned with the steel pipe body 3 and aligned with the probe position of the detection component 41 installed inside the mounting block 42. By turning on the pneumatic diaphragm pump 63, the pneumatic diaphragm pump 63 can pump the paint inside the paint tank 64. The paint can enter the interior of the connecting pipe 62 through the pneumatic diaphragm pump 63 and finally be sprayed out from the spray nozzle of the marking spray gun 61.

[0036] A threaded block 611 is provided on the lower outer side of the marking spray gun 61, and a protective cover 612 is threadedly connected to the outer side of the threaded block 611. The protective cover 612 is located on the lower outer side of the marking spray gun 61.

[0037] The protective cover 612 can protect the spray nozzle of the marking spray gun 61 when the device is not in use, so as to prevent dust from entering the spray nozzle of the marking spray gun 61 and affecting the spraying of the marking spray gun 61 paint. When the device is in use, the protective cover 612 can be rotated to disengage it from the connected threaded block 611.

[0038] The detection components 41 and 51 are equipped with digital ultrasonic flaw detectors (model TSUT-510) for location analysis and are connected to a spray gun control system. Once the detection component 41 detects a defect on the outer wall of the steel pipe body 3, the marking spray gun 61 can spray paint to mark it. After the outer wall of the steel pipe body 3 is inspected, the detection component 51 can enter the interior of the steel pipe body 3 for inspection. Once a defect is detected on the inner wall of the steel pipe body 3, the marking spray gun 61 can move to the defective area to mark it. The marking spray gun 61 always sprays paint on the upper side of the outer wall of the steel pipe body 3. Subsequent operators can check the inner and outer walls of the steel pipe body 3 based on the marked position and then take appropriate action.

[0039] The electric linear actuators mentioned above are all model HB-DJ801.

[0040] The working principle of this high-temperature resistant thick-walled stainless steel pipe testing device is as follows: A limiting component 2 is set at the upper middle part of the testing platform 1 to fix the steel pipe body 3 to be tested, ensuring that the steel pipe body 3 will not shift its position during the testing process. After the steel pipe body 3 is fixed, an outer wall testing mechanism 4 is set on the outside of the steel pipe body 3. The testing components 41 set in the outer wall testing mechanism 4 are located on the upper and lower sides of the steel pipe body 3, and can move left and right to perform a comprehensive test on the outer wall of the steel pipe body 3. At the same time, the outer left and right sides of the steel pipe body 3 are equipped with... The inner wall inspection mechanism 5, which includes an inspection component 51, can enter the interior of the steel pipe body 3 from both the left and right sides to inspect the inner wall of the steel pipe body 3. This allows for simultaneous inspection of both the inner and outer walls of the steel pipe body 3, improving the accuracy of the inspection. Furthermore, a marking mechanism 6 is installed on the rear side of the inspection table 1. When defects are detected on the inner or outer walls of the steel pipe body 3, the marking mechanism 6 can mark the defective locations with paint, facilitating subsequent inspection and treatment by operators.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
