Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary support structure design for non-destructive testing equipment, and in particular to an imaging frame. Background Technology

[0002] In the field of pipeline inspection, radiographic testing is widely used in non-destructive testing because it can project rays at an angle to clearly display internal defects in pipelines. However, traditional radiographic stands have the following prominent problems in practical applications: Traditional radiographic stands mostly use fixed wheels or ordinary rollers, which have poor contact with the pipeline surface. They are prone to slipping and deviating when moving on circular or curved pipeline surfaces, especially when the pipeline surface is uneven or has dust or oil contamination. This results in high movement resistance and poor stability, leading to insufficient accuracy in the detection position and affecting the reliability of the test results. Traditional radiographic stands lack effective buffering mechanisms, and vibrations are directly transmitted to the detection device, which may damage internal precision components (such as the X-ray source and detector) and affect the service life of the equipment. At the same time, the image blurring caused by vibration also reduces the reliability of the test results and increases the risk of misjudgment.

[0003] It is evident that traditional X-ray stands suffer from inconvenience in movement and insufficient stability. During movement, the X-ray stand is inevitably subjected to vibration and impact, and the lack of buffer and shock absorption design limits its adaptability to pipe diameters, as it can only be adapted to single or a few pipe diameters.

[0063] The method of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0064] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0065] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0066] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0067] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0068] according to Figures 1-15As shown, the imaging frame includes: a support body 1 that primarily supports and fixes the detection device, a fixing plate 2 that further fixes the detection device, and conical wheels 3 that allow movement on the pipeline. The fixing plates 2 are fixedly connected to both sides of the upper end of the support body 1, supporting the front and rear ends of the detection device respectively, ensuring that the front and rear ends of the detection device rest on the fixing plates 2. Multiple conical wheels 3 are fixedly connected to the lower end of the support body 1. The conical wheels 3 are conical in shape, ensuring sufficient contact area with the pipeline and allowing for smooth movement of the detection device. Thus, when the detection device needs to be moved to the next location after detecting one position, simply push the support body 1 placed on the pipeline; the conical wheels 3 fixedly connected to the support body 1 will then allow the detection device to be moved. Simultaneously, to avoid missed defects, tilt detection can adjust the position and clarity of the defect image by changing the incident angle of the X-ray, preventing small defects from being obscured by blurred areas. When tilting the detection device for detection, pushing the support body 1 on the pipeline radially relative to the pipeline will also allow the conical wheels 3 to rotate relative to the pipeline, thereby completing the detection. The imaging frame, through the connection structure between the support body 1 and the conical wheel 3, enables the detection device fixed on the fixed plate 2 to move and rotate relative to the pipeline for detection, which facilitates the handling process of the detection device, saves manpower, and improves detection efficiency.

[0069] To enable the support body 1 to function as a fixed connection between the fixing plate 2 and the conical wheel 3, the support body 1 is composed of a first support part 11, a second support part 12, a connecting part 13, an extension part 14, and a sleeve part 15. These components are fixed by welding to form a stable frame structure. The support body 1 includes: a first support part 11 located at the front end of the entire X-ray frame; a second support part 12 located at the rear end of the entire X-ray frame; a connecting part 13 welded to the fixing plate; and an extension part 14 connected to the sleeve part 15 in a T-shape, with the extension part 14 vertically fixed to the top of the sleeve part 15.

[0070] The upper end of the first support part 11 is welded to the fixed plate 2, and the lower end of the first support part 11 is fixedly connected to the extension part 14. The lower end of the extension part 14 is fixedly connected to the sleeve part 15. The extension part 14 and the sleeve part 15 are T-shaped, and the extension part 14 is perpendicular to the sleeve part.

[0071] To securely connect the first support portion 11 and the second support portion 12, one end of the connecting portion 13 is also fixedly connected to the upper end of the first support portion 11, and the other end of the connecting portion 13 is fixedly connected to the upper end of the second support portion 12. The connecting portion 13 welds the first support portion 11 and the second support portion 12 to both ends. The length of the connecting portion 13, which is the distance between the first support portion 11 and the second support portion 12, is sufficient to ensure that the front and rear ends of the detection device can be fixedly placed within the fixing plates 2 on both sides of the bracket body 1, ensuring that the detection window of the detection device is not interfered with by the first support portion 11 and the second support portion 12.

[0072] The upper end of the second support part 12 is also fixedly connected to the fixing plate 2, and the lower end of the second support part 12 is fixedly connected to the extension part 14, and the extension part 14 is fixedly connected to the sleeve part 15.

[0073] The following further describes the main frame 1 of the support structure and its various components. The first support section 11 and the second support section 12 are each formed by welding four long rods together to create a rectangular frame structure. Two long rods form the long sides of the rectangle, and two short rods form the short sides. The four rods intersect perpendicularly at their endpoints, forming a closed rectangular outline. The connecting section 13 consists of two long rods, welded to the upper sides of the first support section 11 and the second support section 12, respectively, at the connection points between the short rods and the long rods. The extension section 14 consists of short rods, similarly welded to the lower ends of the first support rod 11 and the second support rod 12. The extension section 14 is located in the middle of the short rods at the lower ends of the first support section 11 and the second support section 12 and is perpendicular to them. This ensures that the weight of the detection device can be vertically transferred to the conical wheel 3 through the support body 1, thus maintaining a stable center of gravity. The extension section 14 mainly serves to connect the support section and the sleeve section 15. Correspondingly, the two ends of the sleeve section 15 are used to connect to the conical wheel 3.

[0074] To further secure the testing device, the fixing plate 2 includes a support portion 21 that primarily supports the testing device and a protective portion 22 that restricts movement. The lower ends of the two support portions 21 are welded to the upper ends of the first support portion 11 and the second support portion 12, respectively. The protective portion 22 is located on the upper surface of the support portion 21. To further increase the contact area, the protective portion 22 and the support portion 21 are plate-shaped structures. The protective portion 22 and the support portion 21 are integrally bent and formed. The support portion 21, as the main contact part with the testing device, provides support for the testing device. The protective portion 22 further restricts the support position of the testing device, thereby preventing the testing device from sliding off the fixing plate 2. In actual fixing, the front and rear ends of the testing device are placed on the fixing plates 2 on both sides of the upper end of the bracket body 1, and then the testing device is installed and fixed on the fixing plate 2 using packing straps.

[0075] To reduce the vibration caused by unevenness in the pipe or sand and dust adhering to the outside of the pipe when the conical wheel 3 moves on the pipe, a connecting hole 151 is provided on the outer wall of the sleeve portion 15, penetrating both sides of the outer wall of the sleeve portion 15. To reduce vibration on the support body 1 when the conical wheel 3 passes over protrusions or uneven areas, an adjustment mechanism 4 is connected inside the sleeve portion 15. The adjustment mechanism 4 includes an adjusting rod 41 connected inside the sleeve portion 14 and a limiting rod 43 that fixes the adjusting rod 41.

[0076] The adjusting rod 41 includes: an opening 411 through which a limiting rod 43 passes and connects the adjusting rod 41 to the sleeve portion 15; a groove 412 with an annular groove 4121; and a shoulder 413 serving as an axial positioning surface for the conical wheel 3 on the rotating portion 414. The rotating portion 414 connects to the conical wheel 3. The opening 411 has an integrally formed groove 412, shoulder 413, and rotating portion 414 on both sides, with the rotating portion 414 located away from both sides of the opening 411. The main function of the shoulder 413 is to provide an axial positioning surface, and the stepped structure at both ends of the shoulder 413, the groove 412, and the rotating portion 414 restricts the axial movement of the conical wheel 3.

[0077] The opening portion 411 has a limiting hole 415, and the length of the limiting rod 43 is greater than the depth of the limiting hole 415. The limiting rod 43 has threads at both ends, extending into the opening portion 411 from one end and extending out from the other. The extended portions of the limiting rod 43 then extend from both sides of the connecting hole 151 of the sleeve portion 15, and the portion of the limiting rod 43 extending from the key connecting hole 151 is fixedly connected with a nut. The limiting rod 43 and the limiting hole 415 have a clearance fit, and the inner wall of the limiting hole 415 is a smooth surface, allowing the adjusting rod 41 to rotate clockwise and counterclockwise relative to the limiting rod 43 at the contact point between the limiting rod 43 and the adjusting rod 41. However, to limit the rotation angle of the adjusting rod 41 and prevent excessive rotation from causing uncontrolled movement of the conical wheel 3, the inner diameter of the sleeve portion 15 is greater than the diameter of the adjusting rod 41. When the adjusting rod 41 rotates to a certain angle relative to the limiting rod 43, the inner wall of the sleeve 15 restricts the continued rotation of the adjusting rod 41. Therefore, the difference in distance between the sleeve 15 and the adjusting rod 41 can be designed according to the usage requirements, so that the adjusting rod 41 can rotate within a certain range.

[0078] To prevent uncontrolled rotation of the adjusting mechanism 4 inside the sleeve portion 15 due to vibration or tilting, the groove portion 412 is provided with an annular groove 4121 that fixes the buffer rubber ring 42. The adjusting mechanism 4 also includes a buffer rubber ring 42 that provides buffering force. The annular grooves 4121 are respectively provided at the left and right ends of the adjusting rod 41, and are formed around the circumference of the adjusting rod 41. The number of annular grooves 4121 can be set according to actual usage requirements. The rotating part 414 is fixedly connected to the conical wheel 3.

[0079] The cross-sectional shape of the annular groove 4121 is the same as that of the buffer rubber ring 42. This is to increase the contact surface between the annular groove 4121 and the buffer rubber ring 42, thereby improving the connection strength between the buffer rubber ring 42 and the annular groove 4121. It also increases the buffering effect on the adjusting rod 41. The buffer rubber ring 42 is fitted inside the annular groove 4121, with its outer wall abutting against the inner wall of the sleeve portion 15, providing support to both ends of the adjusting rod 41 against the inner wall of the sleeve portion 15. The rotating portions 414 at both ends of the adjusting rod 41 are respectively fixedly connected to the conical wheels 3.

[0080] To avoid insufficient positioning accuracy due to potential wear on the surface of the shoulder 413 if it directly contacts the conical wheel 3, or to prevent increased friction on the contact surface of the conical wheel 3 after wear, making it difficult to move the film holder, the adjustment mechanism 4 also includes a shim 44 clamped together by the shoulder 413 and the conical wheel 3. The edge of the shoulder 413 may scratch the small end circular surface 33 of the conical wheel 3. With the shim 44 installed, the load is evenly distributed to the small end circular surface 33 through the washer, thus protecting the conical wheel 3. The shim 44 acts as an intermediate layer between the shoulder 413 and the conical wheel 3, increasing the contact area and preventing localized stress concentration.

[0081] The adjusting mechanism 4 is located inside the sleeve portion 15 and is rotatably connected to the limiting rod 43 within the sleeve portion 15. This allows the conical wheel 3 to pass over uneven or protruding surfaces on the outer wall of the pipe by rotating clockwise or counterclockwise within a certain range using the adjusting rod 41, without affecting the center of gravity of the detection device supporting the support body 1, thus reducing the vibration frequency of the support body 1. Furthermore, the buffer rubber ring 42 enhances the buffering effect of the conical wheel 3 relative to the support body 1 by supporting the adjusting rod 41 against the inner wall of the sleeve portion 15. Additionally, it also limits the uncontrolled rotation of the adjusting rod 41 within the sleeve portion 15 when the support body 1 vibrates or tilts.

[0082] To secure the conical wheel 3, a through hole 31 is provided in the conical wheel 3. The rotating part 414 passes through the through hole 31 and is fixed to the conical wheel 3 with a nut. In this specific embodiment, four conical wheels 3 are provided, located on both sides of the sleeve part 15 at the lower end of the first support part 11 and the second support part 12, respectively. The conical wheels 3 located below the front and rear ends of the detection device ensure that the center of gravity of the detection device can be smoothly transferred to the conical wheels 3 when it moves.

[0083] The conical wheel 3 includes a large end circular surface 32, a small end circular surface 33, and a conical side surface 34 that directly contacts the pipe. The conical side surface 34 allows the conical wheel 3 to be fixed on pipes of different sizes. The through hole 31 axially penetrates the large end circular surface 32 and the small end circular surface 33. The rotating part 414 passes through the through hole 31 and is fixedly connected to the conical wheel 3 with a nut.

[0084] The small end circular surface 33 is located on the side near the groove portion 412, and is symmetrically arranged along the axis of the small end circular surfaces 33 at both ends of the adjusting rod 41. This allows the conical side surfaces 34 of the conical wheels 3 on both sides of the same adjusting rod 41 to form a V-shape, thereby effectively increasing the contact area between the conical wheels 3 and the pipe and improving stability during movement. At the same time, when the support body 41 needs to be rotated at a certain angle for testing, the V-shaped structure of the two conical wheels 3 on the same adjusting rod 41 can also clamp the pipe, making it less likely for the pipe to come out of the conical wheels 3.

[0085] To facilitate movement by the operator, the upper part of the second support 12 is higher than the upper part of the first support 11. This creates an overall tilt angle where the entire imaging frame is lower in the front and higher in the back, shifting the center of gravity forward. Utilizing the component of gravity to assist in forward movement, the operator only needs to apply a small pushing force to move the equipment, significantly reducing physical exertion and improving inspection efficiency.

[0086] To avoid insufficient overall structural rigidity due to the lack of intermediate support, the connecting part 13 is fixedly connected to the connecting part 13 by welding at both ends. The support rod 5 is located at the middle of the transverse direction of the connecting part 13. The support rod 5 is a short rod, and the connecting parts 13 are welded to both ends of the support rod 5. The support rod 5 forms an I-shaped reinforcing structure by welding the connecting parts 13 at both ends, which effectively distributes the load borne by the connecting part 13, suppresses its bending deformation, and improves the overall rigidity of the support body.

[0087] To prevent slippage and unstable grip during operation due to the smooth surface of the X-ray stand, the surface of the stand body 1 is equipped with anti-slip textures. These textures increase the surface friction coefficient, allowing operators to grip the stand body more firmly when pushing or moving the X-ray stand, reducing the risk of slippage and improving operational safety.

[0088] To prevent slippage of the conical wheel 3 on the pipe surface due to the smoothness of the conical side surface 34 when dust, slight oil stains, or at an angle are present, anti-slip protrusions are evenly distributed on the conical side surface 34, and these protrusions are integrally formed with the conical wheel 3. These anti-slip protrusions increase the contact friction between the conical wheel and the pipe surface, ensuring that the X-ray frame does not easily slip when moving on the pipe.

[0089] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
