Description

Technical Field

[0001] This utility model relates to the technical field of anti-corrosion pipeline quality testing equipment, and in particular to an anti-corrosion pipeline coating testing device. Background Technology

[0002] Corrosion-resistant pipelines are specially treated pipelines with corrosion resistance. Corrosion protection can effectively protect pipelines from corrosion by external environmental factors and extend their service life. Corrosion-resistant pipelines are commonly used in oil and gas transportation, chemical industry, sewage treatment and other fields, especially in harsh environments such as underground, offshore or humid places.

After the coating is completed, it needs to be tested to determine the quality of the coating. However, most of the current testing devices are handheld, which are prone to missing items and are cumbersome to inspect. At the same time, the efficiency of testing the inside of the pipe is low.

[0030] Reference Figure 1-4 This utility model provides a device for detecting anti-corrosion pipeline coatings, comprising:

[0031] The base 100 has a groove 101 on one side of its upper surface, and multiple mounting blocks 102 are fixedly connected to the upper surface of the base 100.

[0032] A transfer roller 200 is mounted on one side of the upper surface of the base 100. A clamping roller 201 is mounted on one side of the transfer roller 200, and an external inspection component 205 and an internal inspection component 206 for coating inspection are mounted on the other side. Mounting blocks 102 are mounted on both sides of the external inspection component 205, and the internal inspection component 206 is mounted on the upper surface of one of the mounting blocks 102. The transfer roller 200 and clamping roller 201 work together to ensure stable transmission of the anti-corrosion pipeline during inspection, avoiding coating inspection errors caused by uneven pipeline slippage. The external inspection component 205 is responsible for inspecting the quality of the pipeline surface coating, quickly and accurately identifying the integrity, thickness, and presence of defects in the surface coating. The internal inspection component 206 is used to inspect the quality of the internal coating of the pipeline, ensuring that both the internal and external coatings meet the requirements.

[0033] The lower end of the transmission roller 200 is equipped with a servo motor and is fixedly connected to the upper surface of the base 100. A slider 202 is rotatably connected to the lower surface of the clamping roller 201, and the outer surface of the slider 202 is slidably connected to the inside of the slide groove 101. A drive motor 203 is fixedly connected to one side of the slide groove 101, and a lead screw 204 is fixedly connected to the output end of the drive motor 203. The outer surface of the lead screw 204 is threaded into the inside of the slider 202. The servo motor drives the pipe forward through the transmission roller 200, ensuring that the pipe maintains a stable speed and position throughout the inspection process. The clamping roller 201, through its rotatable connection to the slider 202 on its lower surface, allows the device to fix pipes of different sizes, enabling them to pass smoothly through the transmission system and improving the stability of the inspection.

[0034] Furthermore, the external detection component 205 includes a mounting frame 2051, the lower surface of which is fixedly connected to the middle of the upper surface of the base 100. Multiple electric push rods 2052 are fixedly connected to the outer surface of the mounting frame 2051, and detection arc plates 2053 are fixedly connected to the output ends of the electric push rods 2052. A controller 2054 is fixedly connected to the front outer surface of the mounting frame 2051. Multiple detection arc plates 2053 are provided, two of which are respectively fixedly connected to the upper ends of the mounting blocks 102 on both sides, and the multiple detection arc plates 2053 are staggered. The electric push rod 2052, through its telescopic action, drives the detection arc plate 2053 to adjust up and down within a predetermined range, ensuring that the detection arc plate 2053 can automatically adjust to the optimal detection position according to the size and location of the pipeline. Multiple detection arc plates 2053 arranged in an alternating manner can simultaneously perform a comprehensive inspection of the pipeline surface. Through their precise arrangement, they cover multiple areas of the pipeline, increasing the detection coverage and accuracy. The controller 2054 is responsible for precisely controlling the movement of the electric push rod 2052, ensuring that each detection arc plate 2053 operates at the appropriate time and position, improving the efficiency and accuracy of the detection.

[0035] Furthermore, the internal detection component 206 includes a main electromagnetic plate 2061, the lower surface of which is fixedly connected to the upper surface of the mounting block 102. A small detection cart 2062 is mounted on the upper surface of the main electromagnetic plate 2061, and a secondary electromagnetic plate 2063 is fixedly connected to the lower surface of the small detection cart 2062. An ultrasonic detector 2064 is fixedly connected to one end of the small detection cart 2062. Both the main electromagnetic plate 2061 and the ultrasonic detector 2064 are wirelessly connected to the inside of the controller 2054. The internal detection component 206 is located on the other side of the external detection component 205. The small inspection vehicle 2062 can move smoothly inside the pipeline under the action of electromagnetic force. The auxiliary electromagnetic plate 2063 interacts with the main electromagnetic plate 2061, allowing the small inspection vehicle 2062 to move freely inside the pipeline for accurate inspection of the pipeline's internal coating. The ultrasonic detector 2064 detects the thickness and integrity of the pipeline's internal coating by emitting and receiving ultrasonic signals, thereby determining the coating's quality and the presence of defects. The main electromagnetic plate 2061 and the ultrasonic detector 2064 are connected to the controller 2054 via wireless signals. The controller 2054 receives and processes the detection data in real time, ensuring that the quality of the pipeline's internal coating can be analyzed and evaluated quickly and accurately.

[0036] During use, the pipe is first placed on the outer surface of one side of the transmission roller 200, and then the drive motor 203 is started to push the clamping roller 201 to clamp the pipe through the lead screw 204. Then, when the transmission roller 200 rotates, the pipe can be transported out. When passing the external detection component 205, the electric push rod 2052 is activated to make the detection arc plate 2053 fit against the outer surface of the pipe to detect the outside of the pipe. At the same time, the small detection cart 2062 is opened and placed inside the pipe. The auxiliary electromagnetic plate 2063 interacts with the main electromagnetic plate 2061, allowing the small detection cart 2062 to move freely inside the pipe. The ultrasonic detector 2064 detects the thickness and integrity of the coating inside the pipe by emitting and receiving ultrasonic signals, thereby judging the quality of the coating and whether there are defects. The received data is transmitted to the controller 2054 for processing and analysis and evaluation of the quality of the coating inside the pipe, which improves the efficiency of use.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
