The composite pipe crack detection device is a device specially used to detect surface and internal cracks of composite pipes. This device combines advanced non-destructive testing technology and image processing technology, and can accurately and quickly identify cracks in composite pipes. It is of great significance to ensure pipeline safety and prevent leakage accidents.

[0003] In the prior art, when detecting cracks in composite pipes, the most important thing is to fix the composite pipes and cooperate with the detection device for detection, but the existing fixing methods are often relatively simple and cannot adapt to composite pipes of different specifications and shapes, resulting in poor detection effect; for this reason, the present invention provides a crack detection device for three-base composite pipe processing.

Through the setting of the rotating ring, the four clamping straight blocks can be guaranteed to move synchronously, and the clamping of the composite pipe is achieved by squeezing the compression springs in the four rings. Through the setting of the limiting slider on the side of the clamping moving block, the limiting slider and the limiting hole are used to limit the clamping moving block when it moves, so that the clamping straight block can only move vertically in all directions to ensure the clamping of the composite pipe.

The setting of the rotating ring can ensure the synchronous movement of the four clamping straight blocks, and the clamping of the composite pipe is achieved by squeezing the compression springs in the four rings. The setting of the limiting slider on the side of the clamping moving block allows the clamping moving block to be limited by the limiting slider and the limiting hole when moving, so that the clamping straight block can only move vertically in all directions, thereby ensuring the clamping of the composite pipe.

[0009] Second: The present invention discloses a crack detection device for processing three-base composite pipes. Initially, the clamping straight block is pushed by the compression spring in the ring, so that the clamping straight block squeezes the inner telescopic column, so that the inner telescopic column is pressed inside the installation groove, and at the same time, the bending of one end of the rotatable connecting column due to excessive gravity can be reduced.

The clamping mechanism is not only compact in structure but also easy to operate, and can effectively improve the efficiency and accuracy of crack detection. At the same time, the stability of the composite pipe during the detection process is ensured by four synchronously moving clamping parts, and the error caused by vibration or movement is reduced. The present invention also provides an inner and outer wall detection device for the composite pipe, which can comprehensively detect the crack condition of the composite pipe by scanning the outer and inner walls of the composite pipe. This design not only improves the comprehensiveness of the detection, but also improves the detection efficiency by detecting the inner and outer walls at the same time.

[0011] In summary, the crack detection device for three-base composite pipe processing described in the present invention realizes comprehensive, efficient and accurate detection of composite pipes with different radii and lengths through innovative clamping mechanism and inner and outer wall detection device design. At the same time, the device is easy to operate and safe to use, and has broad application prospects and important practical value. BRIEF DESCRIPTION OF THE DRAWINGS
