Description

Technical Field

[0001] The invention relates to the technical field of pipeline detection, and in particular to a pipeline strain monitoring device for special equipment detection. Background Art

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

[0003] A patent application with application number CN201710645079.7 discloses a detection device for municipal pipelines, comprising a pair of annular skeletons respectively clamped on the two ends of the pipe to be tested, and the end faces of the annular skeletons are provided with clamping bosses clamped with the inner wall or outer wall of the pipe to be tested. The outer ring surface and the inner ring surface of the annular skeleton are both provided with a plurality of connecting parts for fixing tensioning ropes. The connecting part of the annular skeleton on one side is connected to the corresponding connecting part of the annular skeleton on the other side through a tensioning rope. The tensioning rope is connected to a probe for detecting the performance of the pipe through a sliding part, and the probe detects the performance of the pipe along the arrangement direction of the tensioning rope.

[0004] In summary, when strain monitoring is carried out on the outer walls of different installed pipelines, blind spots are easily formed at the locations where the pipelines are connected to the monitoring devices. These areas that are difficult to monitor will cause deviations in the pipeline strain detection results, and thus fail to accurately reflect the actual strain status of the pipelines, making it difficult for potential safety hazards of the pipelines to be detected in a timely manner.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1: See Figure 1-Figure 4The present invention provides a technical solution: a pipeline strain monitoring device for special equipment detection, comprising a driving mechanism 1, the driving mechanism 1 comprising a first support frame 101, the outer surface of the first support frame 101 is provided with a first groove 102, the inner wall of the first support frame 101 is fixedly connected with a first push rod 103, the output end of the first push rod 103 is fixedly connected with a first fixed block 104, the outer surface of the first push rod 103 away from the first fixed block 104 is fixedly sleeved with a connecting frame 107, and the connecting frame 107 is away from the first push rod 103. The first end is fixedly connected to the first support frame 101, and the outer wall of the first fixed block 104 is fixedly connected to the first driving motor 105. The output end of the first driving motor 105 passes through the first fixed block 104 and is fixedly connected to a driving roller 106. The outer wall of the driving roller 106 is elastic and has sufficient friction. After the driving rollers 106 on both sides contact the pipeline, they move toward the outer surface of the pipeline under the push of the first push rod 103, and deformation occurs due to contact. The deformation increases the friction between the driving roller 106 and the pipeline, so that the driving roller 106 can fit closely to the outer wall of the pipeline to achieve rolling.

[0025] The adjusting mechanism 2 includes a first sliding frame 201 that is slidably connected to the outer wall of the first supporting frame 101, the outer wall of the first sliding frame 201 is fixedly connected to the second driving motor 202, the output end of the second driving motor 202 passes through the first sliding frame 201 and is fixedly connected to a driving wheel 203, the outer wall of the driving wheel 203 is rollingly connected to the inner wall of the first groove 102, the outer wall of the first sliding frame 201 is fixedly connected to a first connecting rod 204, the inner wall of the first connecting rod 204 on a side away from the first sliding frame 201 is fixedly connected to a second push rod 205, the output end of the second push rod 205 is provided with a detection mechanism 207, the outer wall of one end of the second push rod 205 away from the first connecting rod 204 is fixedly sleeved with a support rod 206, and one end of the support rod 206 away from the second push rod 205 is fixedly connected to the first sliding frame 201 Next, the outer wall of the first sliding frame 201 on one side away from the second push rod 205 is fixedly connected to the second support frame 208, and the end of the second support frame 208 away from the first sliding frame 201 is provided with an auxiliary mechanism 212. The second driving motor 202 drives the driving wheel 203 to contact the outer wall of the pipeline, and forms a clamping effect on the pipeline with the help of the driving wheel 203, so that the device can be firmly attached to the outer wall of the pipeline. The first driving motor 105 drives its corresponding driving wheel 203 to operate, prompting the device to move along the outer wall of the pipeline, and the second driving motor 202 fixed to the outer wall of the first sliding frame 201 drives its associated driving wheel 203 to roll in the first groove 102, so that the first sliding frame 201 can rotate around the center of the pipeline. In this process, the outer surface of the pipeline is strain monitored with the help of the detector 2077.

[0026] 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 one 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 stability for the movement of the first fixed block 104.

[0027] One end of the second support frame 208 away from the first sliding frame 201 is fixedly connected to the third fixed block 209, and the outer surface of the third fixed block 209 away from the second support frame 208 is provided with a second groove 210. The inner wall of the second support frame 208 is fixedly connected to the third drive motor 211. The third drive motor 211 makes the second sliding frame 2121 slide along the outer wall of the third fixed 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 fixed block 209 and can rotate. With this connection and rotation method, the orientation 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 on the interfaces at both ends of the pipeline.

[0028] The working principle of this embodiment is as follows: when it is necessary to perform strain detection on the pipeline, the first support frame 101 is first placed outside the pipeline, and then the first push rod 103 pushes the first fixed block 104 to move toward one side of the pipeline, so that the driving roller 106 contacts the outer wall of the pipeline, and the first driving motor 105 uses the driving roller 106 to allow the entire device to move along the outer wall of the pipeline. During the movement of the first fixed block 104, it will pull the sliding block 109 through the first rotating rod 108 to improve the stability of its own movement process, and the second driving motor 202 uses the driving wheel 203 to make the first sliding frame 201 rotate around the first support frame 101 as the center, thereby driving the detection mechanism 207 to rotate, and finally the first detection frame 2072 and the detector 2077 are used to detect the outer wall of the pipeline.

[0029] Example 2: Please refer to Figure 5-Figure 6On the basis of the first embodiment, the present invention provides a technical solution: the detection mechanism 207 includes a second fixed block 2071 fixedly connected to the second push rod 205, and a detector 2077 is fixedly connected to the inner wall of the second fixed block 2071 on the side away from the second push rod 205. A first detection frame 2072 is provided on the side of the second fixed block 2071 away from the second push rod 205. When the second push rod 205 pushes the second fixed blocks 2071 on both sides toward one side of the pipeline at the same time, the first detection frame 2072 moves toward the auxiliary mechanism 212 under the action of the second fixed block 2071. The inner wall of the first detection frame 2072 is rotatably connected to the second rotating rod 2073 through a rotating shaft, and the end of the second rotating rod 2073 away from the first detection frame 2072 is rotatably connected to the second fixed block 2071.

[0030] The outer wall of one end of the first detection frame 2072 away from the second fixed block 2071 is fixedly connected with a first connecting shaft 2074, the outer wall of one end of the first connecting shaft 2074 away from the first detection frame 2072 passes through the second support frame 208 and is fixedly connected with a first limiting plate 2075, the outer wall of the first limiting plate 2075 on one side close to the first detection frame 2072 is fixedly connected with a first spring 2076, 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 fixed block 2071, and the second fixed block 2071 monitors the outer surface of the pipeline with the aid of a detector 2077 fixedly connected to the inner wall. When the second push plate pushes the second fixed block 2071 to move toward the outer surface of the pipeline, the second rotating rod 2073 rotatably connected to the top of the second fixed block 2071 exerts a force on the first detection frame 2072 to push 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, thereby changing the distance between the detector 2077 in the second fixed block 2071 and the first detection frame 2072 and the outer surface of the pipeline, thereby realizing surface stress monitoring for pipelines of different diameters.

[0031] The working principle of this embodiment is as follows: when performing strain detection on pipes of different diameters, the second fixed block 2071 is pushed toward one side of the pipe by the second push rod 205, so that the detector 2077 is moved close to the outer surface of the pipe, and then the outer surface of the pipe is detected. When the second fixed 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 fixed 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 blind spot area of ​​the strain detection of the outer wall of the pipe.

[0032] Example 3: Please refer to Figure 7-Figure 8 On the basis of the first and second embodiments, 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 driving motor 211, the outer wall of the second sliding frame 2121 on one side close to the third fixed block 209 is rotatably connected to an auxiliary wheel 2122 through a rotating shaft, the outer surface of the auxiliary wheel 2122 is rollingly connected to the inner wall of the second groove 210, the inner wall of the second sliding frame 2121 on one side away from the auxiliary wheel 2122 is fixedly connected to a hydraulic rod 2123, the outer wall of the hydraulic rod 2123 on one side away from the second sliding frame 2121 is fixedly sleeved with a first connecting block 2124, and the outer wall of the hydraulic rod 2123 is fixedly sleeved with a second connecting block 2125.

[0033] 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 flipping angle of the second detection frame 2127 so that the second detection frame 2127 can detect the connection between the pipelines. The output end of the dual-axis motor 2126 passes through the second connecting block 2125 and is fixedly connected to the second detection frame 2127. The second connecting shaft 2128 is fixed to the outer wall of the second connecting block 2125 on one side away from the second detection frame 2127.

[0034] 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 with a second limiting plate 2129, and the second limiting plate 2129 is fixedly connected with a second spring 21210 on the outer wall of one side close to the second connecting block 2125, and the end of the second spring 21210 away from the second limiting plate 2129 is fixedly connected to the first connecting block 2124, and the third driving motor 211 drives the second sliding frame 2121 to rotate, thereby rotating the second detection frame 2127 to different directions for carrying out monitoring work, and the hydraulic rod 2123 can push the second fixed block 2071 close to the pipeline The interface needs to monitor the area to assist in 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 when moving. The dual-axis motor 2126 can drive the second detection frame 2127 to flip to one side of the pipeline, so as to facilitate its strain monitoring operation on the pipeline interface. The second driving motor 202 on the outer wall of the first sliding frame 201 drives the driving wheel 203 to roll in the first groove 102, prompting the first sliding frame 201 to rotate around the center of the pipeline, and then drives the second detection frame 2127 to rotate with the pipeline as the center, thereby expanding the monitoring direction and reducing the possibility of blind spots in monitoring at the pipeline connection.

[0035] The working principle of this embodiment is as follows: when there is a need to perform strain detection on the connection between pipelines, the third driving motor 211 drives the second sliding frame 2121 to slide along the outer wall of the third fixed block 209, and then the second sliding frame 2121 pushes the second connecting block 2125 to the side of the connection of the pipeline with the help of the hydraulic rod 2123, and then the second detection frame 2127 is flipped at a certain angle by the dual-axis motor 2126, so that the second detection frame 2127 can be used to carry out strain detection on the connection of the pipeline. In addition, the first sliding frame 201 is slid along the outer wall of the first support frame 101 by the second driving motor 202, so that the second detection frame 2127 can perform circumferential detection on the connection of the pipeline, thereby reducing the blind spot area of ​​​​strain detection.
