Description
Technical Field
The application relates to the field of electromagnetic ultrasonic detection, in particular to an electromagnetic ultrasonic sensor mounting rack and a sensor mounting and dismounting method.
Background
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
The pressure pipeline is used as a special pressure-bearing device and is widely applied to industries such as petroleum, chemical industry, electric power and the like and urban fuel gas and heat supply engineering. The corrosion detection is carried out on the pressure pipeline, the corrosion in the pipeline is found early, the corrosion degree is quantitatively detected, reliable basic data is provided for the pipeline integrity evaluation, the failure risk evaluation and the residual life prediction, and the purposes of predicting, preventing the pipeline from being damaged and failed can be achieved. At present, in the aspect of realizing quick and on-line quantitative detection of pipeline corrosion, the electromagnetic ultrasonic sensor detection has unique advantages and wide application prospect.
Because the electromagnetic ultrasonic sensor adopts the permanent magnet to provide the bias magnetic field, the electromagnetic ultrasonic sensor has strong magnetism. In the case of detection using an electromagnetic ultrasonic sensor, the sensor needs to be placed or mounted on the workpiece to be detected. When the detected workpiece is made of ferromagnetic materials, the sensor is easy to collide with the detected workpiece under the action of suction force, so that the detected workpiece and the sensor are damaged.
In addition, because the sensor and the detected workpiece have strong adsorption force, the position of the sensor is inconvenient to adjust and move. When the sensor is required to be disassembled after the detection is finished, the sensor is adsorbed on the surface of the detected workpiece and is influenced by suction force between the sensor and the workpiece, so that the sensor is inconvenient to disassemble from the detected workpiece.
It should be noted that the foregoing description of the background art is only for the purpose of providing a clear and complete description of the technical solution of the present invention and is presented for the convenience of understanding by those skilled in the art. The above-described solutions are not considered to be known to the person skilled in the art simply because they are set forth in the background of the invention section.
Disclosure of Invention
The inventor researches and discovers that when the detected workpiece is made of ferromagnetic materials, when the electromagnetic ultrasonic sensor is installed, the sensor is influenced by the suction force between the sensor and the detected workpiece, the suction force between the sensor and the detected workpiece is increased sharply along with the decrease of the distance, and in such a case, an operator is difficult to control the force for holding the electromagnetic ultrasonic sensor, and the sensor is easy to collide with the detected workpiece under the action of the suction force. Also, in detaching the electromagnetic ultrasonic sensor, it is difficult to separate the sensor from the inspected workpiece because the suction force is larger as the distance between the sensor and the inspected workpiece is smaller.
In addition, in order to ensure accurate reliability of defect detection in a pipeline, it is often required that a plurality of sensors detect simultaneously, and the distance between the sensors is as small as possible. Therefore, when the electromagnetic ultrasonic sensor is installed, the sensor is influenced by not only the suction force between the sensor and the detected workpiece, but also the suction force or the repulsive force between the sensors. This not only causes damage to the workpiece being inspected and the sensor, but also easily causes severe collisions between the sensors, resulting in operator injury or sensor damage.
When a plurality of sensors are simultaneously detected, the sensors are often required to be uniformly distributed at equal intervals in the circumferential direction of a detected workpiece. And in order to ensure the accuracy and reliability of defect detection in the pipeline, electromagnetic ultrasonic sensors are required to be arranged as much as possible in a circumferentially allowable space range. This increases the influence of suction or repulsive force between the sensors, thereby increasing the difficulty of installation and removal.

The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Please refer to fig. 1 to 7. In an embodiment of the present application, an electromagnetic ultrasonic sensor mounting frame is provided, and the sensor 100 is used for testing a workpiece 200 to be tested. Specifically, the sensor 100 may be disposed on the surface of the inspected workpiece 200 through the mounting frame, so that the sensor 100 may be used to perform electromagnetic ultrasonic detection on the inspected workpiece 200. In an embodiment of the application, the mounting comprises a connecting frame 2 and a guide 4.
The connecting frame 2 is fixedly connected with the sensor 100, and a guide body 3 capable of driving the sensor 100 to rotate is arranged on the connecting frame 2. The guide 4 is fixed and guides the guide body 3. The guide body 3 can drive the sensor 100 to rotate under the guidance of the guide piece 4. The guide body 3 has a first position in which the sensor 100 is inclined to the surface of the workpiece 200 to be inspected and a second position in which the sensor 100 is mounted to the surface of the workpiece 200 to be inspected, which are switched.
In a specific application scenario, the electromagnetic ultrasonic sensor 100 is in a cuboid shape, and the internal magnetic pole distribution is shown in fig. 1. The right hand direction when the reader is facing fig. 1 is the right hand direction as described in the embodiments of the present application. It is assumed that, at the time of electromagnetic ultrasonic detection of the detected workpiece 200, the bottom surface of the sensor 100 is in contact with the detected workpiece 200, and the suction force between the bottom surface and the detected workpiece 200 is large. When the sensor 100 is installed, the guide body 3 is positioned at the first position, and the sensor 100 is inclined to the surface of the detected workpiece 200 at the moment, so that a preset included angle between the bottom surface of the sensor 100 and the surface of the detected workpiece 200 is ensured. The side of the lower right hand corner of sensor 100 in fig. 1 is the contact side. The guide body 3 is then moved under the guidance of the guide 4, so that the guide body 3 is switched from the first position to the second position and the sensor 100 is rotated. The rotation center is the contact edge, and the rotation direction is the direction that the bottom surface of the sensor 100 approaches the surface of the workpiece 200 to be inspected. When the guide body 3 is located at the second position, the sensor 100 is mounted on the surface of the workpiece 200 to be inspected, that is, the bottom surface of the sensor 100 contacts with the surface of the workpiece 200 to be inspected. When the sensor 100 is disassembled, the guide body 3 moves under the guide of the guide piece 4, so that the guide body 3 is switched from the second position to the first position, and the sensor 100 is driven to rotate. The rotation center is the contact side of the sensor 100, and the rotation direction is the direction in which the bottom surface of the sensor 100 is far away from the surface of the workpiece 200 to be inspected. When the guide body 3 is located at the first position, the sensor 100 is inclined to the surface of the workpiece 200, and a predetermined included angle is formed between the bottom surface of the sensor 100 and the surface of the workpiece 200. Finally, the sensor 100 may be lifted to be completely separated from the surface of the inspected workpiece 200.
The predetermined angle may be within a range that is not too large or too small, such as 30 to 60, depending on the particular configuration and performance of the sensor 100. The side surface of the sensor 100 is close to the detected workpiece 200 due to the fact that the preset included angle is too large, so that the suction force between the side surface of the sensor 100 and the detected workpiece 200 is enhanced, and the sensor 100 is in rollover collision with the workpiece; if the predetermined angle is too small, the suction force between the sensor 100 and the workpiece 200 to be inspected cannot be effectively reduced, so that the electromagnetic acoustic sensor 100 cannot be detached or a large force is required to detach the sensor 100.
The electromagnetic ultrasonic sensor mounting frame provided by the application enables the sensor 100 to rotate by the guide body 3 moving under the guide of the guide piece 4. The sensor 100 is inclined to the surface of the inspected workpiece 200 in the case where the guide body 3 is located at the first position, and the sensor 100 is mounted to the surface of the inspected workpiece 200 in the case where the guide body 3 is located at the second position. This can prevent the sensor 100 from being bumped against the workpiece 200 under the influence of suction force when being mounted, thereby protecting the workpiece 200 and the sensor 100 from damage, and making the dismounting process labor-saving and simple.
In the embodiment of the present application, the structure of the guide 4 for guiding the guide body 3 is not limited, and specifically, the guide 4 is provided with a guide groove 41 for accommodating at least a part of the guide body 3. The guide body 3 can move in the guide groove 41 to drive the sensor 100 to rotate around the first axis. For a smoother rotation of the sensor 100, the connecting frame 2 is provided with one guide body 3 on each side in the first axis direction. Correspondingly, there are two guide members 4, and the two guide members 4 can be fixed on two sides of the connecting frame 2 along the first axis direction respectively. When the sensor 100 rotates, the two side guiding bodies 3 in the first axis direction control the rotating path, and the guiding groove 41 designed according to the preset included angle can enable the guiding bodies 3 to drive the sensor 100 to rotate to the preset included angle, so that the sensor is convenient and accurate.
Wherein the guide body 3 is fixedly connected with the sensor 100. As shown in fig. 4, the guide 4 is fixed to the workpiece 200, and the guide groove 41 is substantially circular arc-shaped, but in other embodiments, the guide groove 41 may be shaped differently. After the sensor 100 and the connecting frame 2 are connected, the center of the guide groove 41 is located at the sensor 100. The position of the guide body 3 is not limited in the embodiment of the present application, and may be directly provided on the sensor 100. In the embodiment of the present application, the guide bodies 3 are fixedly provided at both sides of the connection frame 2 in the first axis direction.
The guide body 3 may have a cylindrical shape, a cylindrical head with a hemispherical bottom, or any other regular or irregular shape, so long as at least a portion of the guide body 3 is capable of extending into the guide groove 41 in the guide 4 and moving. In the embodiment of the application, the guide body 3 is cylindrical, and the top is provided with a chamfer. The shape of the guide 4 is not limited in the embodiment of the present application, and the guide groove 41 may be used to guide the guide body 3. For ease of processing, the guide 4 may be rectangular parallelepiped. By virtue of the movement of the guide body 3 in the guide groove 41, the sensor 100 is driven to rotate, so that the operation is simpler and more convenient.
In an embodiment of the application, the mounting further comprises an insert 22 that can be secured to the sensor 100; the connecting frame 2 is provided with a slot 21 for being inserted by the plug-in 22 so as to drive the sensor 100 to rotate. The embodiment of the present application is not limited to the shape of the connection frame 2 and the connection manner of the sensor 100 and the connection frame 2. For example, the connection frame 2 may be two small cylinders, which are respectively fixed to both side surfaces of the sensor 100 in the first axis direction.
In the embodiment of the present application, the connection frame 2 may be plate-shaped. The connection frame 2 has a first surface for facing the sensor 100 and a second surface facing away from the sensor 100, which communicate through the slot 21. One end of the insert 22 is in contact with the first surface and the other end is in contact with the second surface. Specifically, the slot 21 extends in a direction perpendicular to the first axis, and the slot 21 has a guide portion and a snap-in portion. The guide part is arranged on one side of the connecting frame 2 away from the detected workpiece 200, the guide part enables the connecting frame 2 to form a notch, the width of the guide part along the first axis direction is larger than that of the clamping part along the first axis direction, and the plug-in unit 22 is convenient to insert from the guide part and is fixed at the clamping part. By this arrangement, the sensor 100 can be fixed conveniently, the sensor 100 can follow the rotation of the connecting frame 2 better, and the space occupied by the mounting frame is reduced.
In the embodiment of the application, the mounting frame further comprises an operation handle 1 connected with the connecting frame 2 through a rotating shaft 23, and the operation handle 1 can rotate relative to the connecting frame 2 around the rotating shaft 23. The shaft 23 is parallel to and not coaxial with the first axis. Of course, the rotatable angle of the operating handle 1 cannot be 360 °, and must not rotate continuously at a certain angle, so that the guide body 3 can move along the guide groove 41 to drive the sensor 100 to rotate. In the embodiment without the operating handle 1, the connecting frame 2 can be provided with a part which can be touched by a human hand, so that the human hand can conveniently grasp the mounting frame.
In the embodiment of the application, the angular range of rotation of the operating handle 1 about the rotating shaft 23 relative to the connecting frame 2 is 90 °. As shown in fig. 3, the operation handle 1 can be rotated from the upper surface of the sensor 100 to a vertically upward direction. This is to save space occupied by the device because the operation handle 1 can be rotated to the upper surface of the sensor 100 after the sensor 100 is mounted. Further, a hook 11 may be provided at an end of the handle 1 remote from the rotation shaft 23, and after the handle 1 is rotated to the surface of the sensor 100, the handle 1 may be fixed by the engagement of the hook 11 with other members, so that the sensor 100 and the workpiece 200 to be inspected are firmly fixed. The other member may be any member fixed to the workpiece 200 to be inspected or any member fixed to the guide 4, and the present application is not limited thereto. For example, the other component may be a buckle 51 described below.
When the sensor 100 is removed, the hook 11 and its associated components are first released and the lever 1 is rotated 90 ° to the vertical position shown in fig. 3. Continued pulling of the handle 1 to the right, the guide body 3 slides along the guide groove 41, driving the sensor 100 to rotate. After the guide body 3 reaches the rightmost end of the guide groove 41, the bottom surface of the sensor 100 forms a predetermined angle with the surface of the workpiece 200 to be inspected, so that the suction force between the sensor 100 and the workpiece 200 to be inspected is not large, and the sensor 100 can be directly taken out. Or the handle 1 is pulled down to the right, so that the sensor 100 rotates around the guide body 3 to completely separate from the surface of the detected workpiece 200, and then the sensor 100 is taken out, and the required force is smaller. The installation process of the sensor 100 is the reverse of the above operation, and will not be described herein.
Please refer to fig. 5 to fig. 7. In the embodiment of the application, the mounting frame further comprises a first bracket 5 and a second bracket 6 for being fixed on the detected workpiece; a plurality of mounting units distributed along the circumferential direction are arranged between the first bracket 5 and the second bracket 6, and each mounting unit comprises the connecting frame 2 and the guide piece 4.
In particular, the first bracket 5 and the second bracket 6 may be connected together by the guide 4. Both opposite side surfaces of the guide member 4 along the first axis direction may be provided with guide grooves 41, so that adjacent installation units can share the same guide member 4.
