Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline measurement technology, specifically relating to a pipeline thickness measuring device. Background Technology
[0002] Ultrasonic thickness gauges are used to measure pipe thickness, based on the principle of ultrasonic pulse reflection. During operation, the operator holds the main body of the ultrasonic thickness gauge while using the other hand to guide the probe to contact the pipe wall. The operator then observes the data displayed on the main body of the ultrasonic thickness gauge to confirm the pipe thickness. This method lacks convenience, making it inconvenient to perform precise probe contact and measurement in different areas of the pipe wall, especially the lower part of the pipe. Furthermore, it is difficult to set the coupling agent at the detection point location in the lower half of the pipe, affecting the pipe measurement results and reducing operational efficiency.

[0004] This utility model provides the following technical solution: It includes a detector and a detection head. A connecting assembly is provided on the outside of the detector. The connecting assembly includes a top frame and a bottom frame. The top frame is clamped above the bottom frame to secure the connecting assembly to the surface of the pipe to be tested. A positioning assembly and a release assembly are provided on the outside of the connecting assembly. The positioning assembly includes a connecting orifice plate, a connecting rod, and a retaining frame. The retaining frame is close to the outer wall of the top frame and positions the connecting orifice plate in front of the connecting assembly via the connecting rod. The detection head is inserted into the inside of the connecting orifice plate. The release assembly includes a vertical cylinder, a guide tube, and a release shell. The release shell is fixed to the bottom of the connecting orifice plate. The vertical cylinder is positioned outside the connecting orifice plate via the guide tube and communicates with the release shell.
[0005] The top frame is fixedly connected to the top of the bottom frame. An inner clip is fixedly connected to the free end of the top frame and engages with the inside of the free end of the bottom frame. An outer clip is fixedly connected to the free end of the bottom frame and engages with the outside of the free end of the top frame.
[0006] The connecting rod is fixedly connected to the front end of the card frame, the top frame is engaged between the connecting rod and the card frame, and the other end of the connecting rod is fixedly connected to the connecting hole plate.
[0007] The inlet end of the conduit is fixedly connected to the bottom end of the vertical cylinder, and the outlet end of the conduit is fixedly connected inside the connecting orifice plate.
[0008] The output end of the conduit is connected to the release shell, and the inner wall of the release shell has several release holes.
[0009] The release shell corresponds to the center hole of the connecting plate, the detection head passes through the center hole of the connecting plate and is inserted into the release shell, and the bottom end of the release shell has an arc surface.
[0010] The connecting plate has four fastening blocks fixedly connected inside in a cross shape.
[0011] The beneficial effects of this utility model are:
[0012] 1. This utility model uses a connecting component to tighten the probe on the surface of the pipe to be tested from the outside. The positioning component and the release component are positioned together on the outside of the pipe. The probe is inserted into the connecting plate and the release shell to position the probe on the pipe surface and keep it in close contact with the pipe surface. The retaining frame moves along the outer wall of the top and bottom frames, allowing the probe to move along the outside of the pipe and be positioned in different areas. This improves the convenience of operation and facilitates the adjustment, fixed-point contact and measurement of the probe in different areas of the pipe wall.
[0013] 2. In this utility model, the vertical cylinder positioned outside the connecting orifice plate provides space for the injection of coupling agent. The conduit connects the vertical cylinder and the release shell, which can guide the coupling agent entering the vertical cylinder into the release shell. Through several release holes on the inner side wall of the release shell, the coupling agent can be directly released to the detection area of the pipe wall. At the same time, the vertical cylinder can constrain the coupling agent to stay in this area for a long time, so as to facilitate the setting of coupling agent at different detection points on the pipe wall, thereby improving the pipe measurement effect and improving the work efficiency.

Detailed Implementation
[0020] Please see Figures 1-4 The present invention provides the following technical solution: it includes a detector 1 and a detector head 11. A connecting component 2 is provided on the outside of the detector 1. The connecting component 2 includes a top frame 21 and a bottom frame 22. The top frame 21 is clamped above the bottom frame 22 to tighten the connecting component 2 on the surface of the pipe to be tested. A positioning component 3 and a release component 4 are provided on the outside of the connecting component 2. The positioning component 3 includes a connecting orifice plate 31, a connecting rod 32 and a retaining frame 33. The retaining frame 33 is close to the outer wall of the top frame 21 and the connecting rod 32 positions the connecting orifice plate 31 in front of the connecting component 2. The detector head 11 is inserted into the inside of the connecting orifice plate 31. The release component 4 includes a vertical cylinder 41, a guide tube 42 and a release shell 43. The release shell 43 is fixed to the bottom of the connecting orifice plate 31. The vertical cylinder 41 is positioned on the outside of the connecting orifice plate 31 through the guide tube 42 and communicates with the release shell 43.
[0021] In this implementation plan: the detection head 11 is connected to the detection instrument 1. During operation, the detection head 11 contacts the surface of the pipe to be measured, and the two work together to perform pipe thickness measurement.
[0022] The connecting component 2 is used to connect the positioning component 3 and the release component 4, and is also used to connect the pipe to be tested from the outside. The connecting component 2 consists of a top frame 21 and a bottom frame 22. The top frame 21 is fixedly connected to the top of the bottom frame 22. An inner clamp 211 is fixedly connected to the free end of the top frame 21, and the inner clamp 211 is engaged with the inside of the free end of the bottom frame 22. An outer clamp 221 is fixedly connected to the free end of the bottom frame 22, and the outer clamp 221 is engaged with the outside of the free end of the top frame 21, so as to facilitate the combination operation of the top frame 21 and the bottom frame 22, and to clamp the top frame 21 on top of the bottom frame 22. After the free ends of the top frame 21 and the bottom frame 22 are separated, by expanding the top frame 21 and the bottom frame 22, the top frame 21 and the bottom frame 22 can be fitted onto the outside of the pipe to be tested. After the top frame 21 and the bottom frame 22 are tightened together, the connecting component 2 can be tightened onto the surface of the pipe to be tested, which facilitates the tightening and positioning of the connecting component 2 onto the pipe, thereby positioning the positioning component 3 and the release component 4 on the outside of the pipe.
[0023] The positioning assembly 3 consists of a connecting orifice plate 31, a connecting rod 32, and a retaining frame 33. The retaining frame 33 is fitted tightly against the outer wall of the top frame 21. The connecting rod 32 is fixedly connected to the front end of the retaining frame 33. The top frame 21 is engaged between the connecting rod 32 and the retaining frame 33. The other end of the connecting rod 32 is fixedly connected to the connecting orifice plate 31, facilitating the installation and removal of the positioning assembly 3 onto the connecting assembly 2. The detection head 11 is inserted into the center hole of the connecting orifice plate 31. Four fastening blocks 34 arranged in a cross shape are fixedly connected inside the connecting orifice plate 31. Through their own deformation and recovery under stress, the fastening blocks 34 can clamp the detection head 11 from the outside into the center hole of the connecting orifice plate 31, facilitating the positioning of the detection head 11 on the outside of the pipeline.
[0024] The release assembly 4 consists of a vertical cylinder 41, a conduit 42, and a release shell 43. The release shell 43 is fixedly connected to the bottom of the connecting orifice plate 31. The input end of the conduit 42 is fixedly connected to the bottom end of the vertical cylinder 41, and the output end of the conduit 42 is fixedly connected inside the connecting orifice plate 31, stably connecting the release assembly 4 and the positioning assembly 3. The release shell 43 corresponds to the center hole of the connecting orifice plate 31. The detection head 11 passes through the center hole of the connecting orifice plate 31 and is inserted into the release shell 43, so that the detection head 11 can effectively contact the pipe wall.
[0025] The connecting component 2 is tightened onto the surface of the pipe to be tested from the outside, positioning the positioning component 3 and the release component 4 together on the outside of the pipe. The detection head 11 is inserted into the connecting orifice plate 31 and the release shell 43 to position the detection head 11 on the pipe surface and keep it in close contact with the pipe surface. The clamping frame 33 moves along the outer wall of the top frame 21 and the bottom frame 22, allowing it to move along the outside of the pipe with the detection head 11. After the detection head 11 is moved to the designated measurement area, the clamping frame 33 and the connecting rod 32 cooperate to clamp onto the top frame 21 or the bottom frame 22, positioning the detection head 11 in the designated measurement area. The operation is simple, facilitating the adjustment, point contact and measurement of the detection head 11 in different areas of the pipe wall. The bottom end of the release shell 43 has an arc surface 431, allowing the bottom end of the release shell 43 to fit against the pipe wall, ensuring the stability and smoothness of the positioning component 3 and the release component 4 when moving along the outer wall of the top frame 21 and the bottom frame 22 outside the connecting component 2.
[0026] The vertical cylinder 41 moves with the connecting orifice plate 31 and is positioned in the designated measurement area. The vertical cylinder 41 provides space for the injection of coupling agent. The output end of the conduit 42 is connected to the release shell 43, so that the conduit 42 connects the vertical cylinder 41 and the release shell 43. The coupling agent that enters the vertical cylinder 41 can be guided into the release shell 43 through the conduit 42. Several release holes 432 are opened on the inner side wall of the release shell 43. The coupling agent can be directly released into the detection area of the pipe wall through the several release holes 432. At the same time, the vertical cylinder 41 can constrain the coupling agent to stay in this area for a long time, so as to facilitate the setting of coupling agent at different detection points on the pipe wall, allowing the detection head 11 to effectively contact the coupling agent, which can improve the pipe measurement effect and improve the work efficiency.
