Description
Technical Field
[0001] This utility model relates to the field of pipeline flaw detection technology, and in particular to a pipeline radiographic flaw detection crawling support. Background Technology
[0002] The pipeline radiographic testing crawler, also known as a pipeline crawler for radiographic testing, is a device specifically designed for detecting internal defects and wall thickness in pipelines. It mounts an X-ray flaw detector on a driven crawling trolley, which is wirelessly controlled and positioned inside the pipeline to be inspected. This device can move freely inside the pipeline, carrying the radiographic testing equipment, enabling comprehensive internal inspection. It typically consists of a mechanical structure, a power system, a control system, and the radiographic testing equipment. It features a wide range of pipeline diameters and strong environmental adaptability, playing a vital role in engineering construction and equipment maintenance. It effectively improves the accuracy and efficiency of pipeline inspection, ensuring project safety and quality.
[0003] In existing technologies, when using a pipeline X-ray inspection crawler to inspect pipelines, the crawler vehicle and the X-ray inspection machine are placed separately. Therefore, before pipeline inspection, the X-ray inspection machine needs to be fixedly installed together with the crawler vehicle. However, in current installation methods, the X-ray inspection machine is typically fixed to the crawler vehicle by connecting brackets and bolts or screws with the aid of auxiliary tools. This makes the installation and fixing of the X-ray inspection machine cumbersome and inconvenient for quick installation and use. It also makes it difficult to disassemble the X-ray inspection machine for subsequent maintenance, thus causing inconvenience in the assembly and disassembly of the X-ray inspection machine on the pipeline crawler. Utility Model Content
[0004] The main purpose of this utility model is to provide a crawling support for pipeline radiographic testing, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A pipeline radiographic testing crawling bracket includes a vehicle body and an X-ray flaw detector. A mounting plate is fixedly connected to the rear end of the vehicle body, and auxiliary moving wheels are movably connected to both sides of the rear end of the mounting plate. The X-ray flaw detector is fixedly connected to the top of the mounting plate via a fixing mechanism, which includes a support base, a fixing plate, a connecting shaft, a first bevel gear, a screw, a second bevel gear, and an arc-shaped clamping plate. A set of symmetrical support bases is fixedly connected to the top surface of the mounting plate, and a set of symmetrical fixing plates are fixedly connected to the opposite walls of the symmetrical support bases. The connecting shaft is movably connected between the support bases via first rotating rods at both ends, and first bevel gears are fixedly connected to both ends of the outer wall of the connecting shaft. The screw is movably connected to the fixing plate via a second rotating rod at one end, and the second bevel gear is fixedly connected to one end of the second rotating rod and meshes with the first bevel gear. The arc-shaped clamping plate is movably connected to the screw via a connecting plate on the bottom surface.
[0007] Preferably, a set of symmetrical support seats with arc-shaped notches on the top surface of the mounting plate are fixedly installed on the top surface of the mounting plate, and a first rotation hole is also provided on the lower part of the front wall of the support seat.
[0008] Preferably, a first rotating rod is fixedly installed at both ends of the connecting shaft, and the first rotating rod is movably installed in the first rotating hole. A knob is also fixedly installed on the rear end wall of the first rotating rod.
[0009] Preferably, the opposing walls of the symmetrical support bases are each fixedly mounted with a set of symmetrical fixing plates, and the side walls of the fixing plates are provided with second rotating holes. The top surface of the mounting plate and the area between the support bases are also provided with two sets of symmetrical sliding grooves.
[0010] Preferably, a second rotating rod is fixedly installed on the inner end of the screw, and the second rotating rod is movably installed in the second rotating hole. A second bevel gear is fixedly installed on the inner end of the second rotating rod, and the second bevel gear meshes with the first bevel gear.
[0011] Preferably, a connecting plate is fixedly installed at the bottom end of the arc-shaped clamping plate, and a screw hole is provided on the side wall of the connecting plate and threadedly connected to the screw rod through the screw hole. A slider is also fixedly installed at the bottom end of the connecting plate, and the slider is movably installed in the slide groove.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the fixing mechanism places the X-ray flaw detector on the top surface of the mounting plate, with both ends of the X-ray flaw detector positioned within the arc-shaped recesses on the support base. Rotating the knob located on the rear wall of the rear support base rotates the knob, which in turn drives the connecting shaft via a first rotating rod. This rotating shaft then drives the first bevel gears at both ends to rotate, causing the first bevel gears to mesh and drive the second bevel gears on both sides to rotate. The second bevel gears, in turn, drive the screw via a second rotating rod, causing the arc-shaped clamping plate to pass through the side wall of the bottom connecting plate. The screw holes on the upper part move inward along the screw rod, and the symmetrical arc-shaped clamps on the left and right sides will move relative to each other until the two ends of the X-ray flaw detector are clamped and fixed between the arc-shaped clamps and the knob cannot be turned. This achieves the purpose of quickly installing and fixing the X-ray flaw detector on the vehicle body for use, and also facilitates disassembly when the X-ray flaw detector needs to be maintained. Compared with the existing technology, the fixed mechanism provides convenience for the assembly and disassembly of the X-ray flaw detector on the pipeline crawling support.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0020] like Figure 1 - Figure 4As shown, a pipeline X-ray flaw detection crawling bracket includes a vehicle body 1 and an X-ray flaw detector 4. A mounting plate 2 is fixedly connected to the rear end of the vehicle body 1, and auxiliary moving wheels 3 are movably connected to both sides of the rear end of the mounting plate 2. The X-ray flaw detector 4 is fixedly connected to the top of the mounting plate 2 via a fixing mechanism 5. The fixing mechanism 5 includes a support base 6, a fixing plate 8, a connecting shaft 11, a first bevel gear 13, a screw 15, a second bevel gear 17, and an arc-shaped clamping plate 18. A set of symmetrical support bases 6 are fixedly connected to the top surface of the mounting plate 2. Furthermore, a set of symmetrical fixing plates 8 are fixedly connected to the opposite walls of the symmetrical support base 6. The connecting shaft 11 is movably connected between the support base 6 through the first rotating rods 12 at both ends. The outer walls of the connecting shaft 11 are also fixedly connected to the first bevel gears 13. The screw 15 is movably connected to the fixing plate 8 through the second rotating rod 16 at one end. The second bevel gear 17 is fixedly connected to one end of the second rotating rod 16 and meshes with the first bevel gear 13. The arc-shaped clamp 18 is movably connected to the screw 15 through the connecting plate 19 on the bottom surface.
[0021] like Figure 2 and Figure 3 As shown, a set of symmetrical support seats 6 with arc-shaped notches on the top surface of the mounting plate 2 are fixedly installed on the top surface. The set of symmetrical support seats 6 with arc-shaped notches on the top surface can play the role of mounting support for the X-ray flaw detector 4. A first rotating hole 7 is also provided below the front wall of the support seat 6. The first rotating hole 7 is used to cooperate with the first rotating rod 12 to realize the rotation operation.
[0022] like Figure 4 As shown, a first rotating rod 12 is fixedly installed at the front and rear ends of the connecting shaft 11, and the first rotating rod 12 is movably installed in the first rotating hole 7. A knob 14 is also fixedly installed on the rear end wall of the first rotating rod 12. Rotating the knob 14 can drive the first rotating rod 12 to rotate in the first rotating hole 7, and cause the first rotating rod 12 to drive the connecting shaft 11 to rotate. During the rotation of the connecting shaft 11, the first bevel gears 13 at both ends of the outer wall will rotate synchronously.
[0023] like Figure 2 and Figure 3 As shown, a set of left-right symmetrical fixing plates 8 are fixedly installed on the opposite walls of the front and rear symmetrical support bases 6, and a second rotating hole 9 is provided on the side wall of the fixing plate 8. The second rotating hole 9 is used to cooperate with the second rotating rod 16 to realize the rotation operation. Two sets of left-right symmetrical sliding grooves 10 are also provided on the top surface of the mounting plate 2 and between the support bases 6. The sliding grooves 10 are used to cooperate with the slider 21 to realize the guiding sliding operation.
[0024] like Figure 4As shown, a second rotating rod 16 is fixedly installed on the inner end of the screw 15, and the second rotating rod 16 is movably installed in the second rotating hole 9. A second bevel gear 17 is fixedly installed on the inner end of the second rotating rod 16, and the second bevel gear 17 meshes with the first bevel gear 13. The second bevel gear 17 located on both sides of the first bevel gear 13 will rotate synchronously under the rotational meshing action of the first bevel gear 13, and drive the second rotating rod 16 to rotate in the second rotating hole 9. The screw 15 will then rotate through the second rotating rod 16 to provide power for the subsequent movement of the arc-shaped clamp 18.
[0025] like Figure 4 As shown, a connecting plate 19 is fixedly installed at the bottom end of the arc-shaped clamping plate 18, and a screw hole 20 is provided on the side wall of the connecting plate 19. The connecting plate 19 is threadedly connected to the screw rod 15 through the screw hole 20. A slider 21 is also fixedly installed at the bottom end of the connecting plate 19, and the slider 21 is movably installed in the slide groove 10. Driven by the rotation of the screw rod 15, the connecting plate 19 will move inward along the screw rod 15 through the screw hole 20 on the side wall. When moving, the slider 21 installed on its bottom surface will slide in the slide groove 10, and drive the arc-shaped clamping plate 18 on the top surface to move synchronously until the left and right arc-shaped clamping plates 18 move relative to each other and are in close contact with the outer wall of the X-ray flaw detector 4, so that the knob 14 can no longer be turned. The two ends of the X-ray flaw detector 4 can be clamped and fixed between the arc-shaped clamping plates 18, so as to facilitate the quick installation and fixing of the X-ray flaw detector 4 on the vehicle body 1 for use.
[0026] The specific operating principle of the fixing mechanism 5 in conjunction with the pipeline radiographic testing crawler is as follows:
[0027] Before performing flaw detection on the pipeline, the X-ray flaw detector 4 is placed on the top surface of the mounting plate 2, with both ends of the X-ray flaw detector 4 resting on symmetrical support seats 6 with arc-shaped recesses on the top surface of the mounting plate 2. The support seats 6 support the X-ray flaw detector 4 on the top surface of the mounting plate 2. Then, the knob 14 located below the rear wall of the rear support seat 6 is rotated. The knob 14 will drive the first rotating rod 12 to rotate within the first rotating hole 7 on the support seat 6. The first rotating rod 12 will drive the connecting shaft 11 to rotate, causing the connecting shaft 11 to drive the first rotating hole 7 at both ends of the outer wall. After the first bevel gear 13 rotates, it will synchronously drive the second bevel gears 17 on both sides to rotate under the action of rotational meshing. The second bevel gears 17 will drive the second rotating rod 16 to rotate in the second rotating hole 9 opened on the side wall of the fixed plate 8, and further drive the screw 15 to rotate through the second rotating rod 16. During the rotation of the screw 15, the connecting plate 19 will be forced to move inward along the screw 15 through the screw hole 20 opened on the side wall. The slider 21 installed on the bottom surface of the connecting plate 19 will slide in the groove 10 opened on the top surface of the mounting plate 2 to connect the two sides. The connecting plate 19 serves as a guide for movement, and the arc-shaped clamping plate 18 mounted on the top surface of the connecting plate 19 will also move along with the connecting plate 19. At this time, the two sets of arc-shaped clamping plates 18, which are symmetrical on the left and right, will move relative to each other until the arc-shaped clamping plates 18 are tightly attached to the outer wall of the X-ray flaw detector 4, so that the knob 14 can no longer be turned. In this way, the two ends of the X-ray flaw detector 4 can be clamped and fixed between a set of symmetrical arc-shaped clamping plates 18, thereby achieving the purpose of quickly installing and fixing the X-ray flaw detector 4 onto the vehicle body 1 for use. When in use, the vehicle body 1 moves... During the process, the vehicle body 1 will move the X-ray flaw detector 4 mounted on the mounting plate 2 by the auxiliary moving wheels 3. During the movement, the X-ray flaw detector 4 will be used to detect flaws inside the pipeline. When the X-ray flaw detector needs to be maintained later, the knob 14 is rotated in the opposite direction to release the clamping and fixing of the two ends of the X-ray flaw detector 4, and then the X-ray flaw detector 4 can be removed from the support base 6. This facilitates disassembly. Compared with the existing technology, the fixed mechanism 5 makes it easier to install and remove the X-ray flaw detector 4 on the pipeline crawling support.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
