The cylinder 105 is fixedly installed at the middle position of the top of the top frame 101 by bolts. The ultrasonic detection probe 109 is fixedly installed at the bottom end of the cylinder 105 by screws. The ultrasonic detection probe 109 is electrically connected to the thickness detection body 104 through a wire. The movement of the cylinder 105 drives the ultrasonic detection probe 109 to press down and contact the surface of the heat exchanger wind tube for thickness detection, and the measurement result is displayed on the display screen. The detection tooling body 100 is also provided with:

[0026] The arc adjustment clamping and fixing mechanism includes a clamping and fixing component, a movable adjustment component and a support and connection component. The clamping and fixing component is arranged on the inner side of the movable splint 102, the movable adjustment component is arranged at the inner middle position of the movable splint 102, and the support and connection component is arranged at the connection between the end of the clamping and fixing component and the end of the movable splint 102. When the detection tool body 100 detects the thickness of air ducts with different diameters, the arc adjustment clamping and fixing mechanism can adjust the inner surface of the movable splint 102 to the clamping angle, which is convenient for the detection tool body 100 to clamp and fix the heat exchanger air ducts with different diameters when detecting the thickness, thereby improving the convenience of the detection tool body 100 in arc adjustment clamping and fixing for detecting the thickness of the heat exchanger air duct.

[0027] In order to facilitate the clamping and fixing of the air duct and the detection of thickness through the clamping and fixing assembly, in this embodiment, preferably, the clamping and fixing assembly includes a connecting clamp 1027 arranged at the middle position on the inner side of the movable clamp 102, and clamp bodies 1021 are installed on both sides of the connecting clamp 1027 through connecting pins. The clamp body 1021 is an arc-shaped structure, and the two clamp bodies 1021 are symmetrically arranged, which facilitates the movable clamp 102 to drive the clamp body 1021 to be clamped on the surface of the air duct and fixed when it moves, and to detect the clamping and fixing of the air duct.

[0028] In order to facilitate the angle adjustment of the clamping plate body 1021 by moving the adjustment component, and facilitate the clamping and fixing detection of air ducts with different diameters, in this embodiment, preferably, the movable adjustment component includes a screw 1026 rotatably connected to the middle position inside the movable clamping plate 102, one end of the screw 1026 is fixedly connected to the surface of the connecting clamping plate 1027 by a screw, and the other end of the screw 1026 is located on the surface of the movable clamping plate 102 and is rotatably connected to the internal threaded adjustment wheel 1025, which facilitates the rotation of the internal threaded adjustment wheel 1025 to drive the screw 1026 to move. When the screw 1026 moves, the connecting clamping plate 1027 moves and drives the clamping plate body 1021 to adjust the angle, so that the clamping plate body 1021 can be adjusted to clamp and fix air ducts with different diameters.

[0029] In order to facilitate the support connection of the other side after the angle adjustment of the splint body 1021 through the support connection assembly, in this embodiment, preferably, the support connection assembly includes a slide groove 1023 opened at both ends of the splint body 1021, and the internal sliding connection of the slide groove 1023 is connected to the connecting slider 1024. The top of the movable splint 102 is fixed with a support connecting rod 1022 by bolts, and the end of the support connecting rod 1022 is movably connected to the connecting slider 1024 through a connecting pin. When the angle of the splint body 1021 is adjusted, the connecting slider 1024 slides inside the slide groove 1023, so that the support connecting rod 1022 supports and connects to one side surface of the splint body 1021.

[0030] A wear-resistant protection mechanism includes a wear-resistant protection component, which is arranged on the end surface of the ultrasonic detection probe 109. When the detection tool body 100 detects the thickness of the air duct, the wear-resistant protection mechanism protects the end of the ultrasonic detection probe 109 and then detects it. The detection is not easy to cause damage, thereby improving the protection effect of the detection tool body 100 on the ultrasonic detection probe 109 when detecting the thickness of the heat exchanger air duct.

[0031] In order to facilitate wear protection during detection through the wear-resistant protection component and not easily cause damage, in this embodiment, preferably, the wear-resistant protection component includes an external thread structure 1091 opened on the outer surface of the ultrasonic detection probe 109, and the outer surface of the ultrasonic detection probe 109 is rotatably connected to a protective body 1092 through the external thread structure 1091, and the inner bottom end of the protective body 1092 is fixed with a wear-resistant protective plate 1093 by glue, and the protective body 1092 and the wear-resistant protective plate 1093 are rotatably fixed and installed through the external thread structure 1091 for protection.

[0032] In order to facilitate the protection of the bottom end of the ultrasonic detection probe 109 by the wear-resistant guard plate 1093, in this embodiment, preferably, the wear-resistant guard plate 1093 is consistent with the internal bottom end structure of the protective body 1092, and the inner surface of the wear-resistant guard plate 1093 is in contact with the lower surface of the ultrasonic detection probe 109, so that the ultrasonic detection probe 109 can contact the surface of the wear-resistant guard plate 1093 for wear-resistant protection. The close contact makes it convenient for the thickness of the wind tube to be obtained by subtracting the thickness of the wear-resistant guard plate 1093 from the thickness of the test during wear-resistant protection.

[0033] The working principle and use process of the present invention are as follows: when using the heat exchanger duct detection tool, the detection tool body 100 is stably placed at the detection position directly through the bottom contact placement surface of the thickness detection body 104. During the detection, the heat exchanger duct is placed on the surface of the bottom plate 103, and the hand wheel 107 is held to drive the two-way screw rod 106 to rotate. When the two-way screw rod 106 rotates, it drives the two movable slides 108 to move toward each other. When the movable slides 108 move toward each other, they drive the movable clamping plate 102 and the clamping plate body 1021 to move and clamp them on the surface of the duct. After the duct is clamped and fixed, the detection tool body 100 is powered on for detection. The cylinder 105 moves to drive the ultrasonic detection probe 109 to press down and contact the surface of the heat exchanger duct to perform thickness detection, and the measurement result is displayed on the display screen.

[0034] Then, when the inspection tool body 100 is used to inspect the thickness of the heat exchanger duct, and when the heat exchanger ducts of different diameters are fixed, the angle of the clamping plate body 1021 is adjusted, and the internal thread adjustment wheel 1025 is rotated at the end of the screw 1026. When the internal thread adjustment wheel 1025 is rotated, the screw 1026 and the connecting clamping plate 1027 are driven to move. When the connecting clamping plate 1027 moves, the clamping plate body 1021 is driven to a certain tilt angle. When one side of the clamping plate body 1021 moves, the other side drives the connecting slide The block 1024 slides inside the slide groove 1023, and the end of the supporting connecting rod 1022 is always connected to the end of the clamping plate body 1021 to strengthen the support. After the clamping plate body 1021 is adjusted to the angle of clamping and fixing the air duct, the clamping and fixing are supported and reinforced. When the thickness of the heat exchanger air ducts of different diameters is tested, the curvature of the side of the movable clamping plate 102 is adjusted, and the clamping and fixing test is more convenient, thereby improving the convenience of the inspection tool body 100 in adjusting the arc of the heat exchanger air duct thickness test and clamping.

[0035] Finally, before the inspection tool body 100 inspects the thickness of the heat exchanger duct, the protective body 1092 and the wear-resistant protective plate 1093 are rotated and fixed to the end surface of the ultrasonic inspection probe 109 through the external thread structure 1091 for protection. During the inspection, the ultrasonic inspection probe 109 is moved downward by the wear-resistant protective plate 1093 to contact the surface of the duct. When the ultrasonic inspection probe 109 inspects the thickness of the duct, the wear-resistant protective plate 1093 is used to protect the end surface of the ultrasonic inspection probe 109, which is not easy to cause friction damage. At the same time, after the thickness is inspected, the thickness of the heat exchanger duct is subtracted from the thickness of the wear-resistant protective plate 1093 by the thickness of the display screen. This makes it easier for the inspection tool body 100 to protect the end of the ultrasonic inspection probe 109 during inspection, thereby improving the protection effect of the inspection tool body 100 on the ultrasonic inspection probe 109 when inspecting the thickness of the heat exchanger duct.

[0036] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
