Description

Technical Field

[0001] This invention relates to the field of pipeline inspection technology, and in particular to an integrated inspection device and method for measuring pipeline diameter and weld reinforcement. Background Technology

[0002] In numerous industrial sectors such as oil, natural gas, and chemicals, pipelines play a crucial role in transporting various media. Pipeline diameter and weld reinforcement are important indicators of pipeline quality and safety. Even minor changes in pipeline diameter can indicate internal corrosion, deformation, or blockages. These problems can affect media transport efficiency and, in severe cases, even lead to pipeline rupture and leakage, resulting in catastrophic consequences. As a critical component of pipeline connections, the weld reinforcement directly reflects welding quality. Abnormal weld reinforcement may conceal internal defects such as porosity and cracks, increasing the risk of pipeline leaks.

[0003] However, existing pipeline inspection devices are limited in function. Most devices can only perform one of the functions of pipeline diameter measurement and weld reinforcement detection, and cannot perform the detection simultaneously. Therefore, in actual inspection, multiple devices need to be equipped and multiple operations are required, which increases the inspection cost and time, reduces the inspection efficiency, and results in poor measurement accuracy due to poor data synchronization. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated detection device and method for measuring pipe diameter and weld reinforcement, which can simultaneously detect pipe diameter and weld reinforcement, thereby improving detection efficiency and accuracy.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An integrated detection device for pipe diameter measurement and weld reinforcement measurement, comprising:

[0007] Mounting bracket for connecting a pipe cart that is capable of moving axially within the pipe;

[0008] The detection assembly includes a connector, a first detection element, and a second detection element. One end of the connector is rotatably connected to the mounting base. The first detection element is disposed on the mounting base and configured to measure the rotation angle of the connector about the mounting base. The second detection element is disposed at the other end of the connector and is capable of abutting against the inner wall of the pipe to measure the thickness of the pipe.

[0009] The aforementioned integrated detection device for measuring pipe diameter and weld reinforcement includes a clamping member located at the end of the connector away from the mounting base. The clamping member is used to fix the second detection element to the connector.

[0010] The aforementioned integrated detection device for measuring pipe diameter and weld reinforcement includes a clamping member with a wheel groove, in which a roller is rotatably connected and rolls against the inner wall of the pipe.

[0011] The aforementioned integrated detection device for measuring pipe diameter and weld reinforcement height includes a clamping member with at least two wheel grooves at one end near the pipe, and at least one roller is rotatably connected in each wheel groove.

[0012] The aforementioned integrated testing device for measuring pipe diameter and weld reinforcement includes a clamping component comprising two clamping blocks, which are capable of engaging with the connector and clamping the second testing component.

[0013] The aforementioned integrated testing device for measuring pipe diameter and weld reinforcement includes a mounting base with a rotating groove, at least part of which is inserted into the rotating groove and connected to the mounting base via a pin.

[0014] The aforementioned integrated testing device for measuring pipe diameter and weld reinforcement includes a mounting hole on the mounting base that communicates with the rotating groove, and the first testing element is disposed in the mounting hole.

[0015] In the aforementioned integrated detection device for measuring pipe diameter and weld reinforcement, the mounting base and the second detection element are distributed on both sides of the connector, the included angle between the mounting base and the connector is a first obtuse angle, and the included angle between the second detection element and the connector is a second obtuse angle.

[0016] The aforementioned integrated detection device for measuring pipe diameter and weld reinforcement includes an elastic element between the mounting base and the connector. This elastic element applies a spring force to the connector so that the second detection element abuts against the inner wall of the pipe.

[0017] An integrated detection method for pipe diameter measurement and weld reinforcement measurement, employing the aforementioned integrated detection device for pipe diameter measurement and weld reinforcement measurement, comprising:

[0018] S1: Connect the mounting base to the pipeline vehicle and adjust the position of the connector so that the second detection piece abuts against the inner wall of the pipeline;

[0019] S2: The pipeline vehicle drives the integrated detection device for measuring pipeline diameter and weld reinforcement along the axial direction of the pipeline. The first detection element measures the rotation angle of the connector relative to the mounting base and transmits the angle information to the controller. The second detection element measures the wall thickness of the pipeline and transmits the thickness information to the controller.

[0020] S3: The controller calculates the deformation of the pipeline and the weld reinforcement based on the angle and height information.

[0021] The beneficial effects of this invention are:

[0022] The integrated detection device for pipe diameter measurement and weld reinforcement measurement provided by this invention has a mounting base connected to a pipe trolley, facilitating the movement of the device inside the pipe by the trolley. During movement, a second detection element is positioned at the other end of the connector and abuts against the inner wall of the pipe, enabling the measurement of both the pipe wall thickness and the weld reinforcement height. Because the second detection element abuts against the inner wall of the pipe, changes in the pipe's inner diameter cause the connector to rotate. The first detection element measures the angle of rotation of the connector around the mounting base, thereby calculating the change in the pipe's inner diameter. This integrated detection device for pipe diameter measurement and weld reinforcement measurement can simultaneously measure both the pipe's inner diameter and weld reinforcement height, improving detection efficiency.

[0023] The integrated detection method for pipe diameter measurement and weld reinforcement measurement provided by this invention allows the first and second detection components to work simultaneously when the pipe vehicle is traveling inside the pipe. This synchronously transmits the measured angle and thickness information to the data processing unit, improving data synchronization and thus enhancing measurement accuracy.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] The integrated detection device for measuring pipe diameter and weld reinforcement height provided by this invention can be installed on a pipe truck to simultaneously measure the weld reinforcement height and inner diameter of the pipe, thereby improving detection efficiency and accuracy.

[0039] like Figures 1-2 As shown, the integrated testing device for pipe diameter measurement and weld reinforcement measurement includes a mounting base 1 and a testing component 2. The mounting base 1 is used to connect a pipe cart, which can move axially inside the pipe. The testing component 2 includes a connector 21, a first testing element 22, and a second testing element 23. One end of the connector 21 is rotatably connected to the mounting base 1. The first testing element 22 is disposed on the mounting base 1 and configured to measure the rotation angle of the connector 21 about the mounting base 1. The second testing element 23 is disposed on the other end of the connector 21 and can abut against the inner wall of the pipe to measure the thickness of the pipe.

[0040] The integrated detection device for pipe diameter measurement and weld reinforcement measurement provided by this invention has a mounting base 1 connected to a pipe trolley, facilitating the movement of the device inside the pipe by the trolley. During movement, a second detection element 23 is positioned at the other end of the connector 21 and abuts against the inner wall of the pipe, enabling the measurement of the pipe wall thickness and weld reinforcement. Because the second detection element 23 abuts against the inner wall of the pipe, when the inner diameter of the pipe changes, the second detection element 23 causes the connector 21 to rotate. The first detection element 22 can measure the angle of rotation of the connector 21 around the mounting base 1, thereby calculating the change in the inner diameter of the pipe. The integrated detection device for pipe diameter measurement and weld reinforcement measurement provided by this invention can simultaneously measure the inner diameter of the pipe and the weld reinforcement, improving detection efficiency.

[0041] Mounting base 1 is used to connect to the pipeline truck. It features standardized interfaces, allowing for convenient and quick installation and removal on the pipeline truck, thereby improving the versatility and maintainability of the integrated inspection device for pipeline diameter measurement and weld reinforcement measurement. Simultaneously, mounting base 1 provides support for connector 21.

[0042] This embodiment does not specifically limit the material and shape of the connector 21. Exemplarily, the connector 21 is made of a high-strength, lightweight material, which reduces weight while ensuring structural strength, thereby reducing the load on the integrated detection device for pipe diameter measurement and weld reinforcement measurement. Optionally, the connector 21 is made of aluminum alloy, which is inexpensive and readily available.

[0043] To improve the measurement accuracy of the second detection element 23, in this embodiment, the integrated detection device for pipe diameter measurement and weld reinforcement measurement also includes a clamping element 3. The clamping element 3 is located at the end of the connector 21 away from the mounting base 1, and is used to fix the second detection element 23 to the connector 21. After the clamping element 3 fixes the second detection element 23, it ensures that the second detection element 23 will not shift or loosen during the measurement process, so that the second detection element 23 can abut against the inner wall of the pipe under various working conditions, thereby improving the measurement accuracy.

[0044] Optionally, the second detection element 23 can be a thickness detection sensor based on the principle of electromagnetic induction, such as the eddy current sensor of the KAMANDKD2306 series. By making close contact with the inner wall of the pipe, the second detection element 23 can measure the thickness change of the pipe wall in real time. When a weld is detected, the second detection element 23 can accurately measure the magnetic field information of the weld reinforcement height, and then calculate the value of the weld reinforcement height.

[0045] The clamping member 3 and the connecting member 21 can be connected by bolts or by snap-fit. For example, the clamping member 3 and the connecting member 21 are connected by existing bolts. The clamping member 3 includes two clamping blocks 32, which can engage with the connecting member 21 and clamp the second detection member 23. Bolt connection is simple to operate and provides a secure connection.

[0046] For example, the integrated inspection device for pipe diameter measurement and weld reinforcement measurement also includes two first locking bolts 6 and two second locking bolts 7. See also Figure 1 Two first locking bolts 6 can be inserted through the bottom end of the clamping member 3 to fix the clamping member 3 and the connecting member 21, and two second locking bolts 7 can be inserted through the top end of the clamping member 3 to fix the clamping member 3 and the second detection member 23.

[0047] The two clamping blocks 32 are hinged to prevent loss. Each clamping block 32 is provided with a receiving groove. When the two clamping blocks 32 are engaged, they form a receiving cavity containing at least a portion of the connecting member 21. In use, the two clamping blocks 32 are engaged with the end of the connecting member 21 away from the mounting base 1 for initial fixation, and then fixed with bolts. It is understood that the connecting member 21 and the clamping member 3 are provided with through holes that allow bolts to pass through. After the bolts are inserted into the clamping member 3 and the connecting member 21, nuts are used to connect the bolts to fix the clamping member 3 and the connecting member 21. Bolts and nuts are readily available and easy to connect.

[0048] In other embodiments, one of the clamping blocks 32 is provided with a threaded hole, and the bolt passes through the other clamping block 32 and the connector 21 in sequence, and then screws into the threaded hole to fix the connector 21 and the clamping member 3.

[0049] To reduce the friction between the integrated pipe diameter measurement and weld reinforcement measurement device and the pipe, in this embodiment, the clamping member 3 has a wheel groove 31, within which a roller 4 is rotatably connected. The roller 4 rolls against the inner wall of the pipe. The contact mode between the integrated pipe diameter measurement and weld reinforcement measurement device and the inner wall of the pipe is changed from sliding friction to rolling friction, reducing frictional resistance, decreasing power consumption, and improving the service life of the integrated pipe diameter measurement and weld reinforcement measurement device. Simultaneously, it improves the stability of the second detection element 23 during movement, avoiding the jamming and vibration that may occur due to sliding friction, thus improving the stability and accuracy of the detection.

[0050] A support shaft is inserted into the wheel groove 31 and is fixedly connected to the wheel groove 31. A roller 4 is rotatably connected to the support shaft. The roller 4 has a limiting hole, and a bearing is connected inside the limiting hole. The outer ring of the bearing is interference-fitted with the wall of the limiting hole, and the inner ring of the bearing is interference-fitted with the support shaft. The bearing makes the movement of the roller 4 smoother.

[0051] For easy disassembly, the two ends of the support shaft can be threaded. After the support shaft passes through the wheel groove 31, the two ends of the support shaft are tightened with nuts to fix the support shaft and the clamping part 3.

[0052] In other embodiments, the roller 4 may also be fixedly connected to the support shaft, and the support shaft is rotatably connected to the wheel groove 31.

[0053] This embodiment does not specifically limit the number of grooves 31, nor does it specifically limit the number of rollers 4 in each groove 31. For example, the clamping member 3 has at least two grooves 31 near the pipe end, and at least one roller 4 is rotatably connected in each groove 31. Multiple grooves 31 can improve the fault tolerance of the integrated detection device for pipe diameter measurement and weld reinforcement measurement. Even if one groove 31 is damaged, the rollers 4 in the remaining grooves 31 can still roll on the inner wall of the pipe, reducing friction.

[0054] Specifically, each clamping block 32 in the clamping member 3 has a wheel groove 31 at its top, and a roller 4 is rotatably installed in each wheel groove 31. After the two clamping blocks 32 are engaged to clamp the second detection member 23, the two wheel grooves 31 are located at both ends of the second detection member 23, so that the roller 4 in the wheel groove 31 can roll more smoothly on the inner wall of the pipe.

[0055] In other embodiments, the clamping member 3 can be integrally machined. The upper end of the clamping member 3 is provided with three wheel grooves 31. The second detection member 23 is fixedly connected in the middle wheel groove 31, and the rollers 4 are rotatably connected in the remaining two wheel grooves 31. The lower end of the clamping member 3 has an opening for accommodating the connecting member 21. After the connecting member 21 is inserted into the opening, the connecting member 21 and the clamping member 3 are fixed by bolts.

[0056] The rotatable connection between the mounting base 1 and the connector 21 can be achieved through a bearing connection or a hinge connection. In this embodiment, the mounting base 1 and the connector 21 are hinged. The mounting base 1 has a rotating groove 11, and at least a portion of the connector 21 is inserted into the rotating groove 11 and connected to the mounting base 1 by a pin. The connector 21 is inserted into the rotating groove 11, and the groove wall of the rotating groove 11 provides a limiting effect on the connector 21, preventing it from shaking and improving motion stability. Simultaneously, the pin connection is convenient and facilitates disassembly and maintenance.

[0057] The first detection element 22 can be installed on the outer surface of the mounting base 1 or inside the mounting base 1. For example, the mounting base 1 has a mounting hole that communicates with the rotating groove 11, and the first detection element 22 is disposed in the mounting hole. The first detection element 22 is disposed in the mounting hole, which protects and fixes the first detection element 22. The mounting hole and the rotating groove 11 communicate with each other, which facilitates the first detection element 22 to detect the angle through which the connecting member 21 has rotated.

[0058] The first detection element 22 can measure the angle change of the connector 21 relative to the mounting base 1 in real time and with high precision. When the inside of the pipe is deformed, the angle of the connector 21 will change because the connector 21 will abut against the inner wall of the pipe. The first detection element 22 can accurately detect the angle change of the connector 21. Through the pre-established mathematical model of the pipe and the angle change information measured by the first detection element 22, the deformation of the pipe, i.e. the inner diameter of the pipe, can be calculated.

[0059] For example, the first detection element 22 is an angular displacement sensor. It should be noted that the angular displacement sensor is a conventional electrical component in the art, and its structure, connection method and operation method are conventional settings, which will not be described in detail here.

[0060] In this embodiment, an elastic element 5 is provided between the mounting base 1 and the connector 21. The elastic element 5 applies elastic force to the connector 21 so that the second detection element 23 abuts against the inner wall of the pipe. The elastic element 5 provides stable support for the connector 21, ensuring that the second detection element 23 abuts against the inner wall of the pipe, improving measurement accuracy. At the same time, it can also buffer the impact force generated during the operation of the integrated detection device for pipe diameter measurement and weld height measurement to a certain extent, protecting the integrated detection device from damage. The elastic element 5 can be an existing spring, which is readily available.

[0061] To improve the stability of the integrated detection device for pipe diameter measurement and weld reinforcement measurement within the pipe, in this embodiment, the mounting base 1 and the second detection element 23 are distributed on both sides of the connecting member 21. The included angle between the mounting base 1 and the connecting member 21 is a first obtuse angle, and the included angle between the second detection element 23 and the connecting member 21 is a second obtuse angle. The obtuse angle between the mounting base 1 and the connecting member 21 prevents the integrated detection device from getting stuck on the inner wall of the pipe during its movement, thus improving stability. The obtuse angle between the second detection element 23 and the connecting member 21 improves the accuracy of the second detection element 23 in measuring pipe thickness.

[0062] Optionally, the range of the first obtuse angle and the second obtuse angle is 110°-130°, such as 110°, 115°, 120°, 125° or 130°, preferably both the first obtuse angle and the second obtuse angle are 120°.

[0063] In other embodiments, the angle values ​​of the first obtuse angle and the second obtuse angle may not be equal.

[0064] This invention also provides an integrated detection method for pipe diameter measurement and weld reinforcement measurement, using the aforementioned integrated detection device for pipe diameter measurement and weld reinforcement measurement, comprising: S1: connecting the mounting base 1 to the pipe trolley, adjusting the position of the connecting member 21 so that the second detection member 23 abuts against the inner wall of the pipe; S2: the pipe trolley drives the integrated detection device for pipe diameter measurement and weld reinforcement measurement along the axial direction of the pipe, the first detection member 22 measures the rotation angle of the connecting member 21 relative to the mounting base 1 and transmits the angle information to the controller, the second detection member 23 measures the wall thickness of the pipe and transmits the thickness information to the controller; S3: the controller calculates the deformation of the pipe and the weld reinforcement based on the angle information and the height information.

[0065] The integrated detection method for pipe diameter measurement and weld reinforcement measurement provided by the present invention allows the first detection element 22 and the second detection element 23 to work simultaneously when the pipe vehicle is traveling inside the pipe, synchronously transmitting the measured angle information and thickness information to the data processing unit, thereby improving the synchronization of data and thus improving the measurement accuracy.

[0066] In step S1, after connecting the standard interface of the mounting base 1 to the pipeline vehicle through a standardized connection method, the elastic element 5 is connected to the mounting base 1 and the connector 21, and the position of the elastic element 5 is adjusted so that it abuts against the inner wall of the pipeline.

[0067] In step S2, when the pipe's inner diameter decreases, the inner wall of the pipe compresses the connector 21, thereby stretching the elastic element 5, causing the connector 21 to rotate outward. Simultaneously, the elastic element 5 stretches the connector 21, causing the second detection element 23 to abut against the inner wall of the pipe, ensuring measurement accuracy. When the pipe's inner diameter increases, the elastic element 5 contracts, pulling the connector 21 inward to rotate and abut against the inner wall of the pipe. During the measurement process, regardless of the change in the pipe's inner diameter, the second detection element 23 always abuts against the inner wall of the pipe, measuring the pipe wall thickness information in real time and uploading it to the controller. The first detection element 22 can detect the angle change of the connector 21 in real time and upload it to the controller.

[0068] In step S3, the controller infers the location of the weld seam based on the pipe wall thickness information transmitted by the second detection element 23 and calculates the weld seam height; the controller can infer the deformation inside the pipe based on the angle information transmitted by the first detection element 22 and the pre-made mathematical model of the pipe, and then calculate the inner diameter of the pipe.

[0069] Therefore, during the measurement process, the first detection element 22 and the second detection element 23 can synchronously upload information to the controller. On the one hand, this can reduce measurement time and improve measurement efficiency; on the other hand, because of the synchronous data transmission, the measurement accuracy is improved.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
