Description

Technical Field

[0001] The utility model relates to a metal weld detection technology, in particular to an X-ray detection device for a cone shell longitudinal weld. Background Art

[0002] Cone shells are important structural components widely used in the petroleum, chemical, aviation, and aerospace industries. Their strong load-bearing capacity, lightweight, and stable structure make them indispensable components in these industries. Cone shells are typically welded after rolling or pressing sheet metal. The quality of the welds directly impacts the overall structural performance and operational safety of the cone shell. Therefore, quality inspection of cone shell welds is crucial. To ensure the inherent weld quality meets operational requirements, cone shell welds are typically inspected using non-destructive testing (NDT). Among various NDT methods, X-ray inspection is one of the most widely used due to its ability to clearly reveal internal weld defects such as pores, slag inclusions, and cracks. However, the structural characteristics of cone shells present technical challenges in weld inspection, particularly for longitudinal welds. The cone shell's different diameters at both ends, resulting in a tapered shape, make it difficult for traditional inspection equipment to quickly and accurately adjust the angle and focal length between the X-ray detector and the weld during inspection. In addition, flaw detector equipment is usually heavy, and the operator's labor intensity is easily increased due to the gravity of the equipment during the adjustment process, affecting the detection efficiency and accuracy. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an X-ray detection device for the longitudinal weld of a cone shell, which can conveniently adjust an X-ray flaw detector and improve detection efficiency and quality.

[0004] In order to solve the above technical problems, the utility model provides an X-ray detection device for the longitudinal weld of a conical shell, including a support frame, an inclined guide rail is provided on the support frame, a bracket is connected above the guide rail, an X-ray flaw detector is fixed on the bracket, a support rod is provided below the guide rail, a spring tension balancer is fixed on the upper end support frame of the guide rail, one end of the spring tension balancer is fixed on the frame and the other end is connected to the X-ray flaw detector, and the bracket is connected to the guide rail so that the X-ray flaw detector can slide up and down along the guide rail.

[0005] The bracket is connected to the guide rail through a guide sleeve so that the X-ray flaw detector can slide up and down along the guide rail.

[0006] The bottom of the bracket is provided with a mounting hole, and the guide rail is provided with limiting holes arranged longitudinally along the guide rail. The mounting hole can be selectively matched with the limiting hole for limiting.

[0007] The bracket is provided with a ratchet tensioner for fixing the X-ray flaw detector.

[0008] The support rod is supported on the surface of the cone shell to be inspected through an adjusting bolt.

[0009] A base is provided at one end of the bottom of the support frame.

[0010] The supporting frame is L-shaped.

[0011] Advantages of this utility model:

[0012] (1) By setting up the guide rail, the X-ray flaw detector can slide up and down along the guide rail. At the same time, the adjusting bolt can further accurately adjust the angle and focal length between the X-ray flaw detector and the cone shell weld to meet the needs of different inspection parts, improve the convenience and flexibility of the inspection, and ensure the reliability of the inspection results.

[0013] (2) By using a spring tension balancer, the weight of the X-ray flaw detector can be partially balanced, significantly reducing the operator's physical exertion. The spring tension balancer converts the gravity of the flaw detector into elastic energy, making it easier to move.

[0014] (3) The X-ray flaw detector is fixed to the bracket by a ratchet tensioner, which ensures the stability of the equipment during the inspection process, prevents deviation caused by movement or vibration, and further improves the safety and accuracy of the inspection.

[0015] This device utilizes a sliding structure of guide rails and guide sleeves, along with a spring tension balancer, to quickly adjust the X-ray detector to the optimal inspection position, reducing complex operation steps and improving inspection efficiency. Furthermore, precise angle and focal length adjustment ensures reliable inspection results and helps detect inherent defects in welds. BRIEF DESCRIPTION OF THE DRAWINGS
