Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic thickness measurement, in particular to an installation structure of a waveguide rod used for ultrasonic thickness measurement. Background Art

[0002] Ultrasonic thickness measurement technology is widely used in the wall thickness measurement of equipment and pipelines in the petrochemical industry. It has a smart structure, simple operation, high data accuracy, and can measure the intuitive thickness data of the measured medium at any time according to demand. At present, the ultrasonic thickness measurement equipment used in the field is mainly handheld ultrasonic thickness measurement instruments, which use manual operation to perform fixed-point thickness measurement on the equipment to be monitored. Although the manual handheld ultrasonic thickness gauge is light and convenient to use, it also has many disadvantages, such as the need to consume a lot of manpower, high altitude and high temperature position measurement is difficult, and there is a great danger; there are errors in manual measurement, whether each measurement is the same point, whether the coupling force provided by the human arm is consistent, whether the probe and the contact surface of the medium are vertical, etc.; the coupling agent used is easy to volatilize, and the amount of coupling is more, less, or moderate, which will directly cause the deviation of the measurement data; temperature changes cause data deviation, etc. The above problems restrict the wider and more popular application of handheld ultrasonic thickness measurement equipment. Therefore, the existing technology uses a waveguide rod that can be fixed to the measured medium and an online ultrasonic thickness measurement equipment that cooperates with it for real-time monitoring, which is suitable for various temperature environments and can operate stably for a long time.

[0003] For example, Chinese patent publication number CN214793042U discloses a device for in-service nondestructive testing of pipelines, which can perform long-term online monitoring or offline multi-point measurement of the wall thickness of pipelines with coating layers such as insulation layers and buried pipelines. The inspection device includes a clamping device and a waveguide rod. The waveguide rod is fixed to the outer surface of the pipeline by the clamping device, the proximal end face of the waveguide rod is in close contact with the pipeline, and the distal end face extends out of the coating layer. The detection device provided by the above technical solution can perform long-term online monitoring or multi-point offline measurement of the thinning of the pipeline wall thickness, axial cracks, etc. caused by corrosion, scouring, etc. in the long-term use of the coating layer pipeline, and there is no need to dig up the insulation layer or the buried layer on the pipeline, which effectively reduces the huge auxiliary workload caused by the disassembly and installation of the coating layer, reduces the working time of workers in harsh environments, and improves the safety of pipeline operation. However, in the device, the waveguide rod is fixed to the measured pipe by a clamp and a plurality of studs, which makes it inconvenient to adjust the position of the waveguide rod, and makes it inconvenient to measure different local positions of the pipe, which affects the convenience of detection. At the same time, the installation and disassembly of the waveguide rod is time-consuming and labor-intensive, which affects the efficiency of subsequent maintenance and repair.

Detailed implementation mode

[0025] The following further describes this patent application in conjunction with embodiments.

[0026] As Figure 1-6 shown, a waveguide rod mounting structure includes a first ferrule plate 3 and a second ferrule plate 4. T-shaped grooves 10 are provided at both ends of the second ferrule plate 4, and T-shaped blocks 9 that are snap-fitted with the T-shaped grooves 10 are fixed at both ends of the first ferrule plate 3. A cartridge clip assembly 1 is provided on the whole formed by the first ferrule plate 3 and the second ferrule plate 4. A connecting rod 5 is fixed on the outer side wall of the second ferrule plate 4, a socket 6 is fixed at one end of the connecting rod 5 away from the second ferrule plate 4, a waveguide rod 7 is inserted into the socket 6, and a clamping assembly 2 is provided between the socket 6 and the waveguide rod 7. When in use, the first ferrule plate 3 and the second ferrule plate 4 are respectively snapped onto the outer side wall of the pipeline to be measured, and after aligning the T-shaped blocks 9 and the T-shaped grooves 10 on the first ferrule plate 3 and the second ferrule plate 4, the T-shaped blocks 9 are inserted into the T-shaped grooves 10, so as to assemble the first ferrule plate 3 and the second ferrule plate 4 into a whole and sleeved on the outer side wall of the pipeline. At this time, there is a certain gap between the inner side walls of the first ferrule plate 3 and the second ferrule plate 4 and the outer side wall of the pipeline. The cartridge clip assembly 1 generates expansion to block the gap between the first ferrule plate 3, the second ferrule plate 4 and the outer side wall of the pipeline, so as to elastically clamp the first ferrule plate 3 and the second ferrule plate 4 to the outer side wall of the pipeline. The waveguide rod 7 is clamped to the socket 6 through the clamping assembly 2, so as to complete the fixed installation of the waveguide rod 7 on the outer side wall of the pipeline to be measured. The waveguide rod 7 transmits ultrasonic waves from the thickness gauge to a local part of the pipeline to be measured, and receives the ultrasonic waves reflected from the object to measure the thickness. When it is necessary to detect the thickness of different local positions of the pipeline, by releasing the expansion of the cartridge clip assembly 1, the fixation of the whole formed by the first ferrule plate 3 and the second ferrule plate 4 on the pipeline can be released, so that the position of the whole formed by the first ferrule plate 3 and the second ferrule plate 4 on the pipeline can be conveniently moved and adjusted, which is convenient for the waveguide rod 7 to measure different local positions of the pipeline, effectively improves the detection convenience, and further effectively improves the measurement operation efficiency of different local positions. By providing the clamping assembly 2, the waveguide rod 7 is quickly clamped to the socket 6, eliminating the operation of screwing multiple bolts to clamp to the outer side wall of the pipeline, simplifying the installation operation, effectively improving the installation and disassembly efficiency of the waveguide rod 7 on the pipeline, facilitating subsequent maintenance, and improving the maintenance efficiency.

[0027] Specifically, as Figure 1-4As shown, the magazine assembly 1 includes arc-shaped rubber blocks 101 fixed inside the first clamping plate 3 and the second clamping plate 4. A cavity 106 is formed inside the arc-shaped rubber blocks 101. A connecting hose 105 that connects the two cavities 106 is provided between the two arc-shaped rubber blocks 101. An external connecting cylinder 102 communicating with the cavity 106 is fixed on the outer side wall of the first clamping plate 3. One end of the external connecting cylinder 102 away from the first clamping plate 3 is threadedly connected with a threaded rod 103 inserted into the external connecting cylinder 102. A piston member 107 that closely fits and adapts to the inner side wall of the external connecting cylinder 102 is fixed on one end of the threaded rod 103 located inside the external connecting cylinder 102. During specific operation, a certain amount of liquid is filled in the external connecting cylinder 102 and the cavity 106. By rotating the threaded rod 103, the threaded rod 103 drives the piston member 107 to move inside the external connecting cylinder 102. Thus, the liquid in the external connecting cylinder 102 is squeezed into the cavity 106 of one of the arc-shaped rubber blocks 101 by the piston member 107 and is synchronously conveyed to the cavity 106 inside the other arc-shaped rubber block 101 through the connecting hose 105. As a result, the two arc-shaped rubber blocks 101 expand synchronously, causing the side walls of the arc-shaped rubber blocks 101 to expand and closely adhere to the pipeline, blocking the gap between the first clamping plate 3, the second clamping plate 4, and the outer side wall of the pipeline. Thereby, the whole formed by the first clamping plate 3 and the second clamping plate 4 is elastically clamped to the outer side wall of the pipeline. Then, by installing the waveguide rod 7 on the socket 6, the fixed installation of the waveguide rod 7 on the outer side wall of the pipeline to be measured is completed. The waveguide rod 7 transmits ultrasonic waves from the thickness gauge to a local part of the pipeline to be measured and receives the ultrasonic waves reflected from the object and transmits them to the thickness gauge for detecting thickness data. When it is necessary to detect the thickness of different local positions of the pipeline, by rotating the threaded rod 103 in the reverse direction, the expansion of the arc-shaped rubber blocks 101 can be released, thereby releasing the fixation of the whole formed by the first clamping plate 3 and the second clamping plate 4 on the pipeline. By rotating the threaded rod 103, the position of the whole formed by the first clamping plate 3 and the second clamping plate 4 on the pipeline can be conveniently moved and adjusted, facilitating the measurement of different local positions of the pipeline by the waveguide rod 7, effectively improving the detection convenience and effectively improving the measurement operation efficiency of different local positions.

[0028] Specifically, as Figure 4 and Figure 5 shown, a joint plate 104 is fixed on one end of the threaded rod 103 located outside the external connecting cylinder 102. Ribs are provided on the surface of the joint plate 104. During specific operation, by manually rotating the joint plate 104, the threaded rod 103 is driven to rotate, which is convenient for operation.

[0029] Specifically, as Figure 1-3As shown in the figure, the card-mounted component 2 includes an L-shaped card slot 202 opened on the side of the socket 6, and a convex rod 201 fixed on the side of the waveguide rod 7 and slidably adapted to the L-shaped card slot 202. Align the convex rod 201 with the open end of the L-shaped card slot 202, vertically insert the waveguide rod 7 into the socket 6, and rotate the waveguide rod 7 by a certain angle to snap the convex rod 201 into the closed end of the L-shaped card slot 202, thereby quickly mounting the waveguide rod 7 onto the socket 6, eliminating the operation of rotating multiple bolts to clamp onto the outer wall of the pipeline, simplifying the installation operation, effectively improving the installation and disassembly efficiency of the waveguide rod 7 on the pipeline, facilitating subsequent maintenance, and improving the maintenance efficiency.

[0030] The working process of the present utility model is as follows: Snap the first card sleeve plate 3 and the second card sleeve plate 4 onto the outer wall of the pipeline to be measured respectively, align the T-shaped clamping blocks 9 and the T-shaped grooves 10 on the first card sleeve plate 3 and the second card sleeve plate 4, and then insert the T-shaped clamping blocks 9 into the T-shaped grooves 10, thereby assembling the first card sleeve plate 3 and the second card sleeve plate 4 into a whole and sleeving it on the outer wall of the pipeline. At this time, there is a certain gap between the inner side walls of the first card sleeve plate 3 and the second card sleeve plate 4 and the outer wall of the pipeline. By rotating the threaded rod 103, the threaded rod 103 drives the piston member 107 to move inside the external cylinder 102, thereby squeezing the liquid in the external cylinder 102 into the cavity 106 of one of the arc-shaped rubber blocks 101 through the piston member 107, and synchronously transporting it to the cavity 106 inside the other arc-shaped rubber block 101 through the connecting hose 105, so that the two arc-shaped rubber blocks 101 expand synchronously, causing the side walls of the arc-shaped rubber blocks 101 to expand and closely adhere to the pipeline, blocking the gap between the first card sleeve plate 3, the second card sleeve plate 4 and the outer wall of the pipeline, thereby elastically clamping the whole formed by the first card sleeve plate 3 and the second card sleeve plate 4 onto the outer wall of the pipeline. Then align the convex rod 201 with the open end of the L-shaped card slot 202, vertically insert the waveguide rod 7 into the socket 6, and rotate the waveguide rod 7 by a certain angle to snap the convex rod 201 into the closed end of the L-shaped card slot 202, thereby quickly mounting the waveguide rod 7 onto the socket 6, thus completing the fixed installation of the waveguide rod 7 on the outer wall of the pipeline to be measured. The waveguide rod 7 transmits ultrasonic waves from the thickness gauge to a local part of the pipeline to be measured and receives the ultrasonic waves reflected from the object to measure the thickness. When it is necessary to detect the thickness of different local positions of the pipeline, by rotating the threaded rod 103 in the reverse direction, the expansion of the arc-shaped rubber blocks 101 can be released, thereby releasing the fixation of the whole formed by the first card sleeve plate 3 and the second card sleeve plate 4 on the pipeline, and then it is convenient to move and adjust the position of the whole formed by the first card sleeve plate 3 and the second card sleeve plate 4 on the pipeline, facilitating the measurement of different local positions of the pipeline by the waveguide rod 7.

[0031] Specifically, as Figure 2-3As shown, the solid section at the open end of the L-shaped card slot 202 is provided as a spring piece 203, and a round convex block 204 is fixed on the inner side surface of the spring piece 203. During specific operation, the round convex block 204 can be elastically tilted by the provided spring piece 203, and the convex rod 201 can cross over the round convex block 204 and enter the closed end of the L-shaped card slot 202. When the convex rod 201 is stuck into the closed end of the L-shaped card slot 202, the round convex block 204 stops the convex rod 201, effectively improving the stability of the waveguide rod 7 when it is installed in the socket 6.

[0032] Specifically, as Figure 1 and Figure 2 shown, a weight increasing block 8 is fixed at the end of the waveguide rod 7, and a rubber sleeve is fitted on the surface of the convex rod 201. During specific operation, the weight increasing block 8 provided can increase the weight at the bottom of the waveguide rod 7, reducing the sway of the waveguide rod 7 after it is installed in the socket 6 under the action of external force. By sleeving a rubber sleeve on the surface of the convex rod 201, the friction on the surface of the convex rod 201 can be increased. When the convex rod 201 is stuck into the closed end of the L-shaped card slot 202, the rubber sleeve and the round convex block 204 interact with each other, further preventing the convex rod 201 from coming out of the L-shaped card slot 202.

[0033] In this application, the expansion generated by the cartridge clip assembly 1 seals the gap between the first cartridge plate 3, the second cartridge plate 4 and the outer side wall of the pipeline, thereby elastically clamping the first cartridge plate 3 and the second cartridge plate 4 to the outer side wall of the pipeline; the waveguide rod 7 is installed on the socket 6 through the installation assembly 2, thereby completing the fixed installation of the waveguide rod 7 on the outer side wall of the pipeline to be measured. The waveguide rod 7 transmits ultrasonic waves from the thickness gauge to a local part of the pipeline to be measured, and receives the ultrasonic waves reflected from the object and transmits them to the thickness gauge for detecting thickness data; when it is necessary to detect the thickness of different local positions of the pipeline, by releasing the expansion of the cartridge clip assembly 1, the fixation of the whole formed by the first cartridge plate 3 and the second cartridge plate 4 on the pipeline can be released, so that the position of the whole formed by the first cartridge plate 3 and the second cartridge plate 4 on the pipeline can be conveniently moved and adjusted, facilitating the measurement of different local positions of the pipeline by the waveguide rod 7, effectively improving the detection convenience and the measurement operation efficiency of different local positions. The waveguide rod 7 is quickly installed on the socket 6 through the provided installation assembly 2, eliminating the operation of screwing multiple bolts to clamp on the outer side wall of the pipeline, simplifying the installation operation, effectively improving the installation and disassembly efficiency of the waveguide rod 7 on the pipeline, facilitating subsequent maintenance, and improving the maintenance efficiency. The round convex block 204 can be elastically tilted by the provided spring piece 203, and the convex rod 201 can cross over the round convex block 204 and enter the closed end of the L-shaped card slot 202. When the convex rod 201 is stuck into the closed end of the L-shaped card slot 202, the round convex block 204 stops the convex rod 201, effectively improving the stability of the waveguide rod 7 when it is installed in the socket 6. The weight of the bottom of the waveguide rod 7 is increased by the provided weight increasing block 8, reducing the sway of the waveguide rod 7 after it is installed in the socket 6 under the action of external force.

[0034] The embodiments of this specific implementation manner are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
