Description

Technical Field

[0001] This application relates to the technical field of flange inspection, and more specifically, to a fixing device for inspecting pipeline flanges. Background Technology

[0002] Pipe flanges are connectors installed at the ends of pipes or at the inlet / outlet of equipment to enable detachable connections between pipes or between pipes and equipment (such as valves and pumps). After production, pipe flanges need to be inspected to ensure they meet usage requirements.

[0003] Currently, the common inspection method involves an operator holding the pipe flange and using calipers to measure whether the pipe port angle of the flange meets the standard. If the angle does not meet the standard, the pipe flange needs to be returned to the factory or scrapped.

[0004] However, during manual inspection, errors are prone to occur due to human operation, which can cause pipe flanges to wobble, leading to measurement errors and reducing the accuracy of the inspection.

[0005] The content in the background section is merely technology known to the public and does not necessarily represent existing technology in this field. Utility Model Content

[0007] According to one aspect of this application, a fixing device for pipe flange inspection is provided, including a base plate, a movable plate, and a fixing component. The base plate has an annular groove at its center for placing the pipe flange. The movable plate is movably fitted onto the base plate in the vertical direction, and a space for placing the pipe flange is formed between the base plate and the movable plate. The fixing component is detachably connected to the lower surface of the movable plate, and when the movable plate moves to a predetermined position, the fixing component abuts against and fixes the pipe wall of the pipe flange.

[0008] According to some embodiments of this application, the fixing component includes multiple fixing plates, and the multiple fixing plates correspond one-to-one with multiple pipes of the pipe flange.

[0009] According to some embodiments of this application, a fixed plate is detachably connected to a movable plate. A flange is provided on the lower surface of the fixed plate near one end of the pipe flange. When the movable plate moves to a predetermined position, the flange abuts against the pipe wall of the pipe flange, and the other part of the lower surface of the fixed plate forms a measuring gap with the pipe port of the pipe flange.

[0010] According to some embodiments of this application, the fixing component further includes a limiting protrusion disposed on the upper surface of the annular groove, for insertion into one of the pipes of the pipe flange, cooperating with the annular groove to restrict the movement of the pipe flange in the horizontal direction.

[0011] According to some embodiments of this application, a guide hole is provided on the movable plate, and the fixing device further includes a limiting component, which includes a guide rod. The guide rod is vertically disposed on the upper surface of the base plate and passes through the guide hole, so that the movable plate moves along the guide rod in the vertical direction.

[0012] According to some embodiments of this application, the limiting component further includes a limiting member, which is vertically disposed on the upper surface of the base plate. The movable plate moves downward along the guide rod in the vertical direction, and the limiting member limits the movable plate to a predetermined position.

[0013] According to some embodiments of this application, the limiting component further includes a reinforcing rib, one end of which is fixedly connected to the base plate and the other side is fixedly connected to the limiting member.

[0014] According to some embodiments of this application, an observation through hole is provided on the movable plate.

[0031] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] According to one aspect of this application, a fixing device for pipe flange inspection is provided. Figure 1 A schematic diagram of the fixing device according to an embodiment of this application is shown; Figure 2 A schematic diagram of the structure of the limiting component according to an embodiment of this application is shown.

[0033] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the fixing device includes a base plate 1, a movable plate 2, and a fixing assembly. The base plate 1 has an annular groove 11 at its center for placing a pipe flange.

[0034] For example, the base plate 1 can be, but is not limited to, a circular or rectangular plate structure. The setting angle of the base plate 1 can be customized according to the detection needs. Multiple annular grooves 11 can be set, and the multiple annular grooves 11 are set concentrically.

[0035] For example, the base plate 1 is rectangular and horizontally arranged. There are two annular grooves 11, which are concentrically arranged, and the pipe flange is placed in the annular grooves 11.

[0036] According to the example embodiment, such as Figure 1 As shown, the movable plate 2 is movably mounted on the base plate 1 in the vertical direction, and a space for placing pipe flanges is formed between the base plate 1 and the movable plate 2.

[0037] For example, the movable plate 2 may be, but is not limited to, a circular or rectangular plate structure, and is arranged parallel to the base plate 1.

[0038] For example, such as Figure 1 As shown, the movable plate 2 has an irregular pentagonal structure. For example, a corner of the rectangular plate structure can be cut off to reduce the weight of the movable plate 2.

[0039] According to the example embodiment, such as Figure 1 As shown, the fixing component is detachably connected to the lower surface of the movable plate 2. When the movable plate 2 moves to a predetermined position, the fixing component abuts against and fixes the pipe wall of the pipe flange.

[0040] For example, the detachable connection method of the fixing component includes, but is not limited to, bolt connection or pin connection. The predetermined position refers to the position where the fixing component moves downward with the moving plate 2, and just abuts against and fixes the pipe wall of the pipe flange, and cannot move further downward.

[0041] Through the above embodiments, this application can create space for the pipe flange by moving the movable plate upwards, placing the pipe flange on the base plate, and then moving the movable plate downwards to reach the predetermined position. This application then uses a fixing component to abut against and fix the pipe wall of the pipe flange, thereby securing the pipe flange and making it easier for operators to inspect, further improving inspection accuracy.

[0042] Figure 3 A schematic diagram of the structure of the fixing component according to an embodiment of this application is shown.

[0043] According to the example embodiment, such as Figure 1 and Figure 3 As shown, the fixing assembly includes multiple fixing plates 31, and each fixing plate 31 corresponds to a multiple pipe of the pipe flange.

[0044] For example, there are 6 fixed plates 31 arranged in a circumferential array. The fixed plates 31 are arranged perpendicular to the lower surface of the movable plate 2.

[0045] Through the above embodiments, this application can fix the entire pipe flange with multiple fixing plates, thereby enhancing the stability of the pipe flange and improving the accuracy of manual inspection.

[0046] According to the example embodiment, such as Figure 1 and Figure 3 As shown, the fixed plate 31 is detachably connected to the movable plate 2. A flange 311 is provided on the lower surface of the fixed plate 31 and at one end near the pipe flange. When the movable plate 2 moves to the predetermined position, the flange 311 abuts against the pipe wall of the pipe flange, and the other part of the lower surface of the fixed plate 31 forms a measuring gap with the pipe port of the pipe flange.

[0047] For example, the detachable connection method of the fixing plate 31 includes, but is not limited to, bolt connection or pin connection. The fixing plate 31 can be an irregular quadrilateral structure, that is, based on a rectangular plate structure, a corner is cut off from the lower surface of the fixing plate 31 to form a bevel. The bevel can form a measuring gap with the pipe port plane of the pipe flange. The flange 311 is located on the bevel and close to the central axis of the pipe flange.

[0048] For example, the fixed plate 31 is bolted to the movable plate 2. The fixed plate 31 is based on a rectangular plate structure, and a corner is cut off on the lower surface of the fixed plate 31 to form a bevel. The bevel can form a measuring gap with the pipe port plane of the pipe flange. The flange 311 is located on the bevel and close to the central axis of the pipe flange.

[0049] Through the above embodiments, this application can fix the pipe of the pipe flange at a predetermined position using a flange, thus restricting the movement of the pipe flange. This application can also determine whether the pipe angle of the pipe flange is qualified by measuring the gap and comparing whether the inclined plane is parallel to the pipe port. Only the operator needs to complete the measurement, which can reduce the labor intensity of the operator.

[0050] According to the example embodiment, such as Figure 1 and Figure 2 As shown, the fixing assembly also includes a limiting protrusion 312, which is disposed on the upper surface of the annular groove 11 and is used to be inserted into one of the pipes of the pipe flange. It cooperates with the annular groove 11 to restrict the movement of the pipe flange in the horizontal direction.

[0051] For example, the limiting protrusion 312 is cylindrical and perpendicular to the base plate 1. The limiting protrusion 312 is fixedly disposed on the upper surface of the annular groove 11. The outer peripheral sidewall of the limiting protrusion 312 contacts the inner wall of the pipe flange and is used to be inserted into one of the pipes of the pipe flange, cooperating with the annular groove 11 to restrict the movement of the pipe flange in the horizontal direction.

[0052] Through the above embodiments, this application achieves horizontal displacement constraint on the pipe flange by using the combination of the limiting protrusion and the annular groove. This application also restricts the circumferential rotation of the pipe flange, further increasing its stability and thus facilitating improved inspection accuracy for operators.

[0053] According to the example embodiment, such as Figure 1 and Figure 3 As shown, the movable plate 2 is provided with a guide hole 21, and the fixing device also includes a limiting component, which includes a guide rod 41. The guide rod 41 is vertically arranged on the upper surface of the base plate 1. The guide rod 41 passes through the guide hole 21, so that the movable plate 2 moves along the guide rod 41 in the vertical direction.

[0054] For example, multiple guide holes 21 can be provided, and the multiple guide holes 21 can be symmetrically distributed. The shape of the guide holes 21 can be, but is not limited to, circular or square. The guide rod 41 can be a circular rod-shaped structure or a rectangular rod-shaped structure, and the guide rod 41 is adapted to the guide holes 21.

[0055] For example, two guide holes 21 are provided, symmetrically distributed, and circular in shape. The guide rod 41 is circular and perpendicular to the base plate 1. The guide rod 41 passes through the guide hole 21, allowing the movable plate 2 to move vertically along the guide rod 41 to approach or move away from a predetermined position.

[0056] Through the above embodiments, this application can use the guide rod and guide hole to make the moving plate move only in the vertical direction, which can avoid the error of horizontal displacement and thus improve the fixing accuracy of the pipe flange.

[0057] According to the example embodiment, such as Figure 2 As shown, the limiting assembly also includes a limiting member 42, which is vertically disposed on the upper surface of the base plate 1. The moving plate 2 moves downward along the guide rod 41 in the vertical direction, and the limiting member 42 limits the moving plate 2 to a predetermined position.

[0058] For example, multiple limiting members 42 can be configured, and these multiple limiting members 42 can be arranged in an array. The limiting member 42 can be rod-shaped, and the vertical cross-section of the limiting member 42 can be, but is not limited to, T-shaped or rectangular, etc. The specific settings can be selected according to the processing requirements.

[0059] The limiting component 42 and the base plate 1 can be either fixedly connected or detachably connected. Fixed connections can be, but are not limited to, welding or bonding. Detachable connections can be, but are not limited to, snap-fit ​​or threaded connections.

[0060] For example, three limiting members 42 are provided, and the three limiting members 42 are distributed in a triangular array, respectively located at the three vertices of the base plate 1. The vertical cross section of the limiting member 42 is inverted T-shaped, and the limiting member 42 is threadedly connected to the base plate 1.

[0061] Through the above embodiments, this application can limit the maximum movable distance of the moving plate by using a limiting component, which can easily ensure the distance between the fixed plate and the pipe port of the pipe flange, avoid excessive compression, and thus easily improve the detection accuracy of the operator.

[0062] According to the example embodiment, such as Figure 2 As shown, the limiting component also includes a reinforcing rib 43, one end of which is fixedly connected to the base plate 1, and the other side is fixedly connected to the limiting member 42.

[0063] For example, the reinforcing rib 43 is a triangular prism structure, which is perpendicular to the base plate 1. The bottom edge of the reinforcing rib 43 is fixedly connected to the base plate 1, and the right-angled edge is fixedly connected to the limiting member 42.

[0064] Through the above embodiments, this application can improve the bending stiffness of the limiting component and extend its service life by using reinforcing ribs.

[0065] According to the example embodiment, such as Figure 1 and Figure 3 As shown, the movable plate 2 is provided with an observation through hole 22.

[0066] For example, there are two observation holes 22, one of which is located at the center of the moving plate 2 and the other is located on one side of the edge of the moving plate 2. The observation holes 22 can facilitate the operator to observe the pipe flange and can reduce the weight of the moving plate 2.

[0067] Through the above embodiments, this application can facilitate observation by adding observation holes, and at the same time, the weight of the moving plate can be reduced by the hole structure, thereby reducing the labor intensity of the operator.

[0068] According to the example embodiment, such as Figure 1 and Figure 3 As shown, a handle 23 is provided on the upper surface of the movable plate 2.

[0069] For example, the handle 23 is fixedly connected to the center of the upper surface of the movable plate 2 and is located above the observation hole 22.

[0070] Through the above embodiments, this application can make it easier for operators to pick up and put down the moving plate by setting a handle, thereby reducing the labor intensity of operators.

[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions of the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
