[0028] like Figure 1-5 As shown, this utility model provides a non-destructive testing device for pipelines, including a platform 1, and a first testing mechanism 2, a second testing mechanism 3 and a rotating mechanism 4 are provided on the top of the platform 1.
[0029] The first detection mechanism 2 includes a connecting plate 201. One end of the connecting plate 201 is fixedly connected to a plurality of support rods 202. One end of the plurality of support rods 202 is connected to the corresponding side of the same support ring 203. The support ring 203 has a plurality of moving holes inside.

One end of the first infrared detection protrusion 205 is provided with a spring 207. The other end of the spring 207 is connected to the outer wall of the support ring 203. A plurality of guide cylinders 206 are fixedly connected to the inner wall of the support ring 203. The inner wall of the guide cylinders 206 is movably connected to the outer wall of the moving rod 204. One end of the moving rod 204 is provided with a connecting rope. One side of the connecting plate 201 is fixedly connected to a first motor 208. The output end of the first motor 208 is drivenly connected to a winder 209. The winder 209 is connected to the moving rod 204 through the connecting rope.
[0030] The rotating mechanism 4 includes a first clamping seat 401, a first bearing seat 402 on one side of the first clamping seat 401, the first bearing seat 402 being rotatably connected to a first connecting ring 403 via a bearing, a gear ring 404 being fixedly connected to the outer wall of the first connecting ring 403, a first gear 405 being meshed with the outer wall of the gear ring 404, a transmission rod 406 being drivenly connected to the inner wall of the first gear 405, one end of the transmission rod 406 being drivenly connected to the output end of a second motor 407, and the second motor 407 being fixedly connected to the top of the platform 1. By setting the rotating mechanism 4, the detection device can drive the pipe to rotate slowly during the detection process, so that the first infrared detection protrusion 205 and the second infrared detection protrusion 304 can contact multiple positions on the inner and outer surfaces of the pipe, thereby ensuring the comprehensiveness of the detection device and avoiding detection blind spots.
[0031] The top of the platform 1 is provided with a sliding groove 6, and a slider 7 is slidably connected to the inner wall of the sliding groove 6. A second clamping seat 8 is fixedly connected to the top of the slider 7. A second bearing seat 9 is fixedly connected to the side of the second clamping seat 8 near the first clamping seat 401. The second bearing seat 9 is rotatably connected to the second connecting ring 10 through a bearing.

By setting the second clamping seat 8, the second bearing seat 9 and the clamping elements 11, the second bearing seat 9 and the second connecting ring 10 can be used for auxiliary rotation.

[0035] Working principle:
[0036] In use, first, one end of the pipe is abutted against the clamping member 11 on one side of the first clamping seat 401. Then, the third motor 13 is started, driving the lead screw 12 to rotate. Since the lead screw 12 and the slider 7 are connected by a thread, the lead screw 12 can drive the slider 7 to move along the slide groove 6. The movement of the slider 7 drives the second clamping seat 8 to move, so that the second clamping seat 8 is close to the clamping member 11 of the first clamping seat 401 to clamp and fix the other end of the pipe. Then, the first motor 208 is started, driving the winder 209 to rotate. Since the winder 209 is connected to the moving rod 204 through a connecting rope, when the winder 209 rotates, the connecting rope will be wound around the winder 209, and the moving rod 204 will be pulled by the connecting rope. When the moving rod 204 moves, it will compress the spring 207, causing the spring 207 to contract. Then, the first electric telescopic rod 14 is started, driving the first detection mechanism 2 to move, so that the second... A detection mechanism 2 enters the interior of the pipe and then shuts off the first motor 208, thereby releasing the winding device 209 from restricting the connecting rope. This allows the connecting rope and the moving rod 204 to move outward under the action of the spring 207, thereby causing the first infrared detection protrusion 205 to move outward and contact the inner wall of the pipe. Then, the second electric telescopic rod 302 is activated, which drives the lifting plate 303 to move downward, causing the lifting plate 303 to move the second infrared detection protrusion 304 downward, so that the second infrared detection protrusion 304 contacts the outer surface of the pipe. Next, the second motor 407 is activated, which drives the transmission rod 406 to rotate. The transmission rod 406 drives the gear 405 to rotate, the gear 405 drives the gear ring 404 to rotate, and the gear ring 404 drives the first connecting ring 403 to rotate. This causes the pipe to rotate through the clamping device 11, thereby comprehensively detecting the outer and inner surfaces of the pipe.
[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
