Description

Technical Field

[0001] This invention relates to the field of pipeline inspection technology, specifically to a pipeline strain monitoring device for special equipment inspection. Background Technology

[0002] In the industrial field, special equipment pipelines are widely used to transport various hazardous media. However, special equipment pipelines may be affected by factors such as force, temperature changes, and humidity changes, which will cause changes in the relative positions of the atoms inside them. This will lead to changes in the shape and size of the pipeline, i.e., strain. If the strain is excessive, the pipeline may rupture, resulting in leakage of hazardous media and threatening human life and the environment.

[0003] Patent application CN201710645079.7 discloses a testing device for municipal pipelines, comprising a pair of annular frames respectively snapped onto both ends of the pipe fitting to be tested. The annular frames have snapping protrusions on their end faces that snap onto the inner or outer wall of the pipe fitting. Both the outer and inner annular surfaces of the annular frames are provided with several connecting parts for fixing tension ropes. The connecting parts of one annular frame are connected to the corresponding connecting parts of the other annular frame via tension ropes. A probe for testing the performance of the pipe fitting is connected to the tension rope via a sliding member. The probe tests the performance of the pipe fitting along the direction of the tension rope.

[0004] In summary, when conducting strain monitoring on the outer walls of different installed pipelines, blind spots are easily formed at the connection between the pipeline and the monitoring device. These difficult-to-monitor areas can lead to deviations in the pipeline strain test results, thus failing to accurately reflect the actual strain condition of the pipeline and making it difficult to detect potential safety hazards in a timely manner.

[0005] To address this, we propose a pipeline strain monitoring device for special equipment inspection. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a pipeline strain monitoring device for special equipment inspection, which has the following beneficial effects:

[0017] 1. This invention, by setting up a driving mechanism, allows the first push rod to adjust the distance between the two driving rollers, enabling the driving rollers to clamp the outer walls of pipes of different diameters. The first driving motor drives the driving rollers to roll tightly against the outer wall of the pipe, and the driving mechanism subsequently drives the detection mechanism to move synchronously. The detection mechanism performs all-round strain monitoring on the outer wall of the pipe and the connection between the pipes, thereby reducing blind spots in the monitoring of the outer wall.

[0018] 2. By setting an adjustment mechanism, the second drive motor causes the first sliding frame to slide along the outer wall of the first support frame with the help of the drive wheel, thereby enabling the first sliding frame to rotate around the first support frame, thus realizing comprehensive monitoring of the outer wall of the pipeline and reducing the monitoring blind spots of the outer wall of the pipeline.

[0019] 3. This invention, by setting up a detection mechanism, pushes the second fixed block closer to the outer wall of the pipe with the second push rod, and then uses a detection instrument fixedly connected to the inner wall of the second fixed block to perform strain detection on the outer wall of the pipe. By controlling the distance between the detection instrument and the pipe with the second push rod, it is possible to detect tiny cracks on the outer wall of the pipe, thereby improving the accuracy of strain monitoring of the outer wall of the pipe.

[0020] 4. By setting up an auxiliary mechanism, the third drive motor uses the second sliding frame to make the second detection frame rotate around the third fixed block. Thus, the second detection frame set at the output end of the hydraulic rod can detect the joint on one side of the pipeline. Furthermore, by controlling the flip angle of the second detection frame and the rotation of the first sliding frame against the first support frame through the dual-axis motor, the blind spot area of ​​the second detection frame when monitoring the pipeline joint can be reduced.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to 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.

[0033] Example 1: See Figures 1-4The present invention provides a technical solution: a pipeline strain monitoring device for special equipment testing, comprising a drive mechanism 1, the drive mechanism 1 including a first support frame 101, a first groove 102 formed on the outer surface of the first support frame 101, a first push rod 103 fixedly connected to the inner wall of the first support frame 101, a first fixing block 104 fixedly connected to the output end of the first push rod 103, a connecting frame 107 fixedly sleeved on the outer surface of the first push rod 103 away from the first fixing block 104, and a connecting frame 107 being located away from the first push rod 103. The first drive motor 105 is fixedly connected to the outer wall of the first fixed block 104 and the first support frame 101. The output end of the first drive motor 105 passes through the first fixed block 104 and is fixedly connected to the drive roller 106. The outer wall of the drive roller 106 is elastic and has sufficient friction. After the two drive rollers 106 contact the pipe, they move towards the outer surface of the pipe under the push of the first push rod 103. Due to the contact, deformation occurs, which increases the friction between the roller and the pipe, so that the drive roller 106 can tightly fit the outer wall of the pipe and roll.

[0034] The adjusting mechanism 2 includes a first sliding frame 201 slidably connected to the outer wall of the first support frame 101. A second drive motor 202 is fixedly connected to the outer wall of the first sliding frame 201. The output end of the second drive motor 202 passes through the first sliding frame 201 and is fixedly connected to a drive wheel 203. The outer wall of the drive wheel 203 is in rolling contact with the inner wall of the first groove 102. A first connecting rod 204 is fixedly connected to the outer wall of the first sliding frame 201. A second push rod 205 is fixedly connected to the inner wall of the first connecting rod 204 on the side away from the first sliding frame 201. A detection mechanism 207 is provided at the output end of the second push rod 205. A support rod 206 is fixedly sleeved on the outer wall of the end of the second push rod 205 away from the first connecting rod 204. The end of the support rod 206 away from the second push rod 205 is fixedly connected to the first sliding frame 201. Next, a second support frame 208 is fixedly connected to the outer wall of the first sliding frame 201 on the side away from the second push rod 205. An auxiliary mechanism 212 is provided at the end of the second support frame 208 away from the first sliding frame 201. The second drive motor 202 drives the drive wheel 203 to contact the outer wall of the pipe. The drive wheel 203 forms a clamping effect on the pipe, so that the device can be firmly attached to the outer wall of the pipe. The first drive motor 105 drives its corresponding drive wheel 203 to rotate, causing the device to move along the outer wall of the pipe. The second drive motor 202 fixed to the outer wall of the first sliding frame 201 drives its associated drive wheel 203 to roll in the first groove 102, so that the first sliding frame 201 can rotate around the center of the pipe. During this process, the strain monitoring work of the outer surface of the pipe is carried out with the help of the detector 2077.

[0035] The inner wall of the first fixed block 104 is rotatably connected to the first rotating rod 108 via a rotating shaft. A sliding block 109 is provided at the end of the first rotating rod 108 away from the first fixed block 104. The inner wall of the sliding block 109 is slidably connected to the first push rod 103. The inner wall of the sliding block 109 is rotatably connected to the first rotating rod 108 via a rotating shaft. The first rotating rod 108 provides a certain degree of stability for the movement of the first fixed block 104.

[0036] A third fixing block 209 is fixedly connected to the end of the second support frame 208 away from the first sliding frame 201. A second groove 210 is formed on the outer surface of the third fixing block 209 away from the second support frame 208. A third drive motor 211 is fixedly connected to the inner wall of the second support frame 208. The third drive motor 211 causes the second sliding frame 2121 to slide against the outer wall of the third fixing block 209. The output end of the third drive motor 211 is fixedly connected to the second sliding frame 2121. The second sliding frame 2121 is attached to the top of the third fixing block 209 and can rotate. With this connection and rotation method, the position of the second detection frame 2127 in the auxiliary mechanism 212 can be changed so that the second detection frame 2127 can be used to carry out strain detection work on the interfaces at both ends of the pipeline.

[0037] The working principle of this embodiment is as follows: When strain testing of the pipeline is required, the first support frame 101 is first placed outside the pipeline. Then, the first fixed block 104 is pushed to one side of the pipeline by the first push rod 103, so that the drive roller 106 contacts the outer wall of the pipeline. The first drive motor 105 enables the entire device to move along the outer wall of the pipeline with the help of the drive roller 106. During the movement of the first fixed block 104, it will pull the sliding block 109 through the first rotating rod 108, thereby improving the stability of its movement process. The second drive motor 202 uses the drive wheel 203 to make the first sliding frame 201 rotate around the first support frame 101, thereby driving the detection mechanism 207 to rotate. Finally, the detection of the outer wall of the pipeline is realized through the first detection frame 2072 and the detection instrument 2077.

[0038] Example 2: Please refer to Figures 5-6Based on Embodiment 1, the present invention provides a technical solution: the detection mechanism 207 includes a second fixing block 2071 fixedly connected to the second push rod 205. A detector 2077 is fixedly connected to the inner wall of the side of the second fixing block 2071 away from the second push rod 205. A first detection frame 2072 is provided on the side of the second fixing block 2071 away from the second push rod 205. During the process of the second push rod 205 pushing the second fixing blocks 2071 on both sides towards the pipe side at the same time, the first detection frame 2072 moves towards the auxiliary mechanism 212 side under the action of the second fixing block 2071. A second rotating rod 2073 is rotatably connected to the inner wall of the first detection frame 2072 through a rotating shaft. The end of the second rotating rod 2073 away from the first detection frame 2072 is rotatably connected to the second fixing block 2071.

[0039] A first connecting shaft 2074 is fixedly connected to the outer wall of the first detection frame 2072 away from the second fixing block 2071. The outer wall of the first connecting shaft 2074 away from the first detection frame 2072 passes through the second support frame 208 and is fixedly connected to a first limiting plate 2075. A first spring 2076 is fixedly connected to the outer wall of the first limiting plate 2075 near the first detection frame 2072. The first spring 2076 assists the first detection frame 2072 in resetting. The first connecting shaft 2074 is used to improve the stability of the first detection frame 2072 during movement. The end of the first spring 2076 away from the first limiting plate 2075 is fixedly connected to the second fixing block 2071. The second fixing block 2071 monitors the outer surface of the pipeline with the help of a detector 2077 fixedly connected to its inner wall. When the second push plate pushes the second fixed block 2071 to move towards the outer surface of the pipe, the second rotating rod 2073 rotatably connected to the top of the second fixed block 2071 will exert a force on the first detection frame 2072, pushing the first detection frame 2072. At this time, the first detection frame 2072 slides on the inner wall of the second support frame 208 due to its own first connecting shaft 2074, and moves upward after being squeezed by the second rotating rod 2073. This can change the distance between the detector 2077 inside the second fixed block 2071 and the first detection frame 2072 and the outer surface of the pipe, thereby realizing the surface stress monitoring work for pipes of different diameters.

[0040] The working principle of this embodiment is as follows: When performing strain testing on pipes of different diameters, the second push rod 205 pushes the second fixing block 2071 toward one side of the pipe, causing the detector 2077 to approach the outer surface of the pipe and thus test the outer surface of the pipe. When the second fixing blocks 2071 on both sides are pushed toward one side of the pipe at the same time, the first detection frame 2072 will move toward the auxiliary mechanism 212 under the action of the second fixing block 2071. At the same time, the second drive motor 202 causes the first sliding frame 201 to rotate around the first support frame 101 through the drive wheel 203, thereby increasing the detection area of ​​the detector 2077 on the outer wall of the pipe and reducing the dead zone area of ​​strain testing on the outer wall of the pipe.

[0041] Example 3: Please refer to Figures 7-8 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the auxiliary mechanism 212 includes a second sliding frame 2121 fixedly connected to the output end of the third drive motor 211. An auxiliary wheel 2122 is rotatably connected to the outer wall of the second sliding frame 2121 near the third fixed block 209 via a rotating shaft. The outer surface of the auxiliary wheel 2122 is rolledly connected to the inner wall of the second groove 210. A hydraulic rod 2123 is fixedly connected to the inner wall of the second sliding frame 2121 away from the auxiliary wheel 2122. A first connecting block 2124 is fixedly sleeved on the outer wall of the hydraulic rod 2123 away from the second sliding frame 2121. A second connecting block 2125 is fixedly sleeved on the outer wall of the hydraulic rod 2123.

[0042] A dual-axis motor 2126 is fixedly connected to the inner wall of the second connecting block 2125. The dual-axis motor 2126 can adjust the rotation angle of the second inspection frame 2127 so that the second inspection frame 2127 can carry out inspection work on the connection between pipes. The output end of the dual-axis motor 2126 passes through the second connecting block 2125 and is fixedly connected to the second inspection frame 2127. A second connecting shaft 2128 is fixed to the outer wall of the second connecting block 2125 on the side away from the second inspection frame 2127.

[0043] The end of the second connecting shaft 2128 away from the second connecting block 2125 passes through the first connecting block 2124. The second connecting shaft 2128 provides stability for the movement of the second connecting block 2125 and is fixedly connected to a second limiting plate 2129. A second spring 21210 is fixedly connected to the outer wall of the second limiting plate 2129 near the second connecting block 2125. The end of the second spring 21210 away from the second limiting plate 2129 is fixedly connected to the first connecting block 2124. The third drive motor 211 drives the second sliding frame 2121 to rotate, thereby rotating the second detection frame 2127 to different positions to carry out monitoring work. The hydraulic rod 2123 can push the second fixed block 2071 closer to the pipeline. The interface requires monitoring of the area to facilitate accurate detection. The second connecting shaft 2128 on the outer wall of the second connecting block 2125 is slidably connected to the inner wall of the first connecting block 2124. This connection method ensures the stability of the second connecting block 2125 during movement. The dual-axis motor 2126 can drive the second detection frame 2127 to flip to one side of the pipeline, which facilitates strain monitoring at the pipeline interface. The second drive motor 202 on the outer wall of the first sliding frame 201 drives the drive wheel 203 to roll in the first groove 102, causing the first sliding frame 201 to rotate around the center of the pipeline, thereby driving the second detection frame 2127 to rotate around the pipeline as the center, expanding the monitoring area and reducing the possibility of monitoring blind spots at the pipeline connection.

[0044] The working principle of this embodiment is as follows: When there is a need to perform strain testing on the connection between pipes, the third drive motor 211 drives the second sliding frame 2121 to slide along the outer wall of the third fixed block 209. Then, the second sliding frame 2121 pushes the second connecting block 2125 towards the connection of the pipe with the help of the hydraulic rod 2123. Then, the second detection frame 2127 is rotated at a certain angle by the dual-axis motor 2126, so that the second detection frame 2127 can be used to perform strain testing on the connection of the pipe. In addition, the first sliding frame 201 is slid along the outer wall of the first support frame 101 by the second drive motor 202, so that the second detection frame 2127 can perform circumferential testing on the connection of the pipe, thereby reducing the dead zone area of ​​strain testing.
