Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-corrosion coating testing technology, specifically to a portable skid-mounted pipeline anti-corrosion coating adhesion testing device. Background Technology

[0002] In the field of pipeline corrosion protection coating inspection, accurate detection of the adhesion between the corrosion protection coating and the pipeline substrate is a crucial measure to ensure the safe and stable operation of pipelines, and is of great significance for improving the overall performance of pipelines and extending their service life. However, traditional pipeline corrosion protection coating inspection devices have some shortcomings in use. Specifically: First, because traditional pipeline corrosion protection coating inspection devices rely on the coordinated work of multiple components and have relatively complex transmission mechanisms, a failure or malfunction of one component can lead to uneven corrosion protection coating peeling speed, and increase the complexity and maintenance difficulty of the system; second, the simple clamping structure design of traditional pipeline corrosion protection coating inspection devices results in a lack of stability in the corrosion protection coating application; finally, the fixed structure design of traditional pipeline corrosion protection coating inspection devices is not flexible enough, resulting in poor adaptability to pipeline diameters.

The lower side of the portable loading unit is connected to a quick clamping unit that clamps the pipe corrosion protection coating. The quick clamping unit is located between the paired skid-mounted support units and is used to clamp the corrosion protection coating of the pipe to be tested. The upper side of the portable loading unit is fixedly connected to an integrated control and detection unit for real-time control and data analysis.

[0004] Preferably, the device fixing unit includes a binding strap fixing buckle, a second binding strap, a first binding strap, a steel guide rail, and a rubber pad. One end of the two steel guide rails with "U-shaped" grooves on their outer arc surfaces is fixedly connected to the first and second binding straps made of polyester material, forming a ring that fits onto the pipe. The first and second binding straps are adjusted and locked to fix the pipe by the binding strap fixing buckle.

[0005] Preferably, the skid-mounted bearing unit includes a driven wheel, an adjusting screw, a height adjusting nut, a housing, a bracket, a knob, an adjusting bracket, a driving wheel, a sliding wheel, a pin, a retaining ring, and a guide wheel bracket. Two positive "V"-shaped brackets are fixedly connected to two inverted "V"-shaped adjusting brackets through the circular housings on both sides and the knob, respectively. Adjusting the height adjusting nut on the adjusting screw can change the height of the driving wheel. The left end of the pin hinges the adjusting bracket to the driven wheel, and the right end is connected to the sliding wheel, which is embedded in the inner arc surface of the outer side of the steel guide rail, through the retaining ring and the guide wheel bracket.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 7 As shown, this utility model provides a technical solution: A portable skid-mounted pipe corrosion protection layer adhesion force testing device includes a device fixing unit, a skid-mounted support unit, and a portable loading unit connected sequentially from bottom to top. The device fixing unit is used to clamp and fix the pipe 3. The skid-mounted support units are arranged in pairs and are used to support the portable loading unit, which provides stable tension for testing the adhesion force of the pipe 3 corrosion protection layer. The lower side of the portable loading unit is connected to a quick clamping unit that clamps the pipe body corrosion protection layer 4. The quick clamping unit is located between the paired skid-mounted support units and is used to clamp the corrosion protection layer 4 of the pipe 3 to be tested. The upper side of the portable loading unit is fixedly connected to an integrated control and detection unit for real-time control and data analysis.

[0022] like Figure 1 , Figure 2 and Figure 5As shown, the device fixing unit includes a binding strap fixing buckle 5, binding strap two 6, binding strap one 7, a steel guide rail 8, and a rubber pad 28. One end of the two steel guide rails 8, which have a U-shaped groove design on their outer arc surfaces, is fixedly connected to the polyester binding strap one 7 and binding strap two 6, forming a ring that fits onto the pipe 3. The binding strap one 7 and binding strap two 6 are adjusted by the binding strap fixing buckle 5 to tighten and fix the pipe 3. The U-shaped groove design on the outer arc surface of the steel guide rail 8 can cooperate with the driven wheel 11 and the driving wheel 27 to ensure that the driven wheel 11 and the driving wheel 27 move only tangentially along the steel guide rail 8. At the same time, the bottom surface of the U-shaped steel guide rail 8 is provided with a gear groove to ensure that the driving wheel 27 can run precisely along the steel guide rail 8 and prevent the driving wheel 27 from slipping.

[0023] A rubber pad 28, which is the same length as the steel guide rail 8, slightly narrower in width, and has trapezoidal teeth on its inner arc surface, is fixedly attached to the side of the steel guide rail 8 that contacts the pipe 3. The installation of the rubber pad 28 not only avoids direct contact between the steel guide rail 8 and the pipe 3, which would damage the anti-corrosion layer of the pipe 3, but also increases the friction between the steel guide rail 8 and the pipe 3, thereby stabilizing the entire device on the pipe 3. The two sides of the steel guide rail 8 are wider than the rubber pad 28, which is to facilitate the later placement of sliding wheels 39 on both sides of the inner arc surface of the steel guide rail 8.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the skid-mounted load-bearing unit includes a driven wheel 11, a lower support rod 12, an adjusting screw 13, a height adjusting nut 14, a housing 15, an upper support rod 16, a bracket 17, a knob 25, an adjusting bracket 26, a drive wheel 27, a sliding wheel 39, a pin 40, a snap ring 41, and a guide wheel bracket 42. The paired positive "V" brackets 17 are fixedly connected to the paired inverted "V" adjusting brackets 26 through the circular housings 15 and the knobs 25 on both sides of their respective sides. The adjusting brackets 26 can be selected according to different pipe diameters to achieve flexible on-site testing. The upper support rod 16 is vertically fixed to the outside of the housing 15. Its lower side is fixedly connected to an adjusting screw 13 that passes through the height adjusting nut 14 and a lower support rod 12 that is hinged to the drive wheel 27. The extension and retraction lengths of the upper support rod 16 and the lower support rod 12 can be controlled by adjusting the relative positions of the nut 14 and the screw 13 to accommodate the loading space height required for testing pipes 3 of different diameters. The drive wheel 27 has trapezoidal teeth on its exterior that match the steel guide rail 8. The lower ends of the two adjusting brackets 26 are respectively hinged to driven wheels 11, which have anti-slip rubber pads on their exteriors and are mounted on the steel guide rail 8, via pins 40. The pins 40 passing through the driven wheels 11 are connected to a sliding wheel 39 embedded in the inner arc surface of the outer side of the steel guide rail 8 via a snap ring 41 and a guide wheel bracket 42.

[0025] like Figure 1 , Figure 2, Figure 3 and Figure 6 As shown, the portable loading unit includes a square handle 9, a housing 10, a second bracket 18, a reinforcing rib plate 19, a reducer 20, a servo motor 22, a transmission rope 23, a tension sensor 24, a roller 31, a support column 32, a support plate 43, a support 44, and a second sliding wheel 45. The portable loading unit is enclosed in a house-shaped housing 10 with a square handle 9 installed on the top. The housing 10 has a square handle 9 on the upper part for easy lifting on site. The second bracket 18 is symmetrically distributed on the left and right sides inside the outer shell 10. The two brackets 18 are vertically connected to the reinforcing rib plate 19 in the middle. The reducer 20 and the servo motor 22 are respectively fixed on the upper and lower sides of the reinforcing rib plate 19. The I-shaped roller 31 that is connected to the transmission rope 23 in the middle is connected to the reducer 20 on one side and is hinged to the support column 32 on the other side. The lower end of the transmission rope 23 is connected to the tension sensor 24 that collects data in real time. Two support plates 43 are provided on the lower side of the middle of the reinforcing rib plate 19. Each support plate 43 is provided with a support 44 on the side close to the transmission rope 23. The second sliding wheel 45 is hinged on the support 44 to ensure that the direction of the tension is perpendicular to the direction of the pipe axis.

[0026] like Figure 1 and Figure 4 As shown, the quick clamping unit includes anti-corrosion layer peeling clamps 33, springs 34, snap ring cylindrical pins 35, wing nuts 36, flat head bolts 37, and washers 38. The upper ends of the two symmetrically distributed "L-shaped" anti-corrosion layer peeling clamps 33 are hinged by snap ring cylindrical pins 35, and the lower ends are toothed anti-slip chucks. The left and right ends of the springs 34 with appropriate preload are supported on the inner sides of the two anti-corrosion layer peeling clamps 33. The flat head bolts 37 can pass through the two anti-corrosion layer peeling clamps 33, pass through the springs 34, and connect to the washers 38 and wing nuts 36 at the ends. The position of the toothed anti-slip chucks can be manually fine-tuned to align with the end of the anti-corrosion layer 4 pre-peeled from the pipe 3 substrate. Adjusting the wing nuts 36 achieves the clamping function of the anti-corrosion layer 4.

[0027] like Figures 1 to 5As shown, the integrated control and detection unit includes a control terminal 1, a data cable 2, a rechargeable power supply 21, an LCD display 29, an integrated circuit board 30, and a communication data interface 46. The rechargeable power supply 21, connected to the integrated circuit board 30, provides power to the entire system at the detection site, eliminating the need for an external power source. The control terminal 1, with its embedded LCD display 29, is connected to the communication data interface 46 via the data cable 2, and then to the integrated circuit board 30. On one hand, through signal transmission from the integrated circuit board 30, the servo motor 22 can drive the drive wheel 27 to slide on the steel guide rail 8. Driven by the drive wheel 27, the driven wheel 11 and the sliding wheel 39, also located on the steel guide rail 8, move, thereby driving the entire device to move on the steel guide rail 8. On the other hand, through another signal transmission from the integrated circuit board 30, the servo motor 22 drives the anti-corrosion layer peeling clamp 33 to pull the anti-corrosion layer 4 on the pipeline 3 to be tested via the transmission rope 23 connected to the series tension sensor 24.

[0028] The overall working principle described above is as follows: (1) Assembly steps of the device S1) Fixing device fixing unit: The steel guide rail 8 in the fixing unit is fixedly installed on the pipe to be inspected 3 by binding strap 1 7, binding strap 2 6 and binding strap fixing buckle 5. S2) Fixed skid-mounted support unit: First, select a skid-mounted support unit that matches the diameter of the on-site pipeline 3. Second, insert the sliding wheel 39 of the skid-mounted support unit into the steel guide rail 8. The upper end of the guide wheel bracket 42 that is screwed to the sliding wheel 39 is connected to the driven wheel 11 through the pin 40 and fixed with the snap ring 41. Then, the entire skid-mounted support unit is fixed on the steel guide rail 8. Finally, adjust the extension of the adjusting screw 13 by adjusting the height adjusting nut 14 so that the driving wheel 27 is in contact with and pre-tightened to an appropriate amount on the outer arc surface of the steel guide rail 8, ensuring that the driving wheel 27 runs along the groove of the track. S3) Install the portable loading unit and quick clamping unit: The upper part of the skid-mounted load-bearing unit bracket 17 and the lower part of the bracket 2 18 supporting the main structure of the portable loading unit are fixedly connected by a pin, thereby installing the portable loading unit. The quick clamping unit is then hung on the lower part of the portable loading unit by the transmission rope 23. S4) Install the integrated control and detection unit: Connect the control terminal 1 to the integrated circuit board 30 and the rechargeable power supply 21 via the data cable 2. On the one hand, connect the servo motor 22 and the drive wheel 27 via the integrated circuit board 30; on the other hand, connect the servo motor 22, the tension sensor 24, and the moving rope 23 via the integrated circuit board 30, thereby assembling the entire device.

[0029] (2) On-site testing procedures S1) Sample preparation: Cut a rectangular anti-corrosion layer 4 with a length of more than 100mm and a width of 20~30mm along the circumference of the pipe to be tested 3, and gently peel off the cut anti-corrosion layer 4 along the width direction to expose the pipe 3 substrate. S2) Anti-corrosion layer clamping: Align the toothed clamp of the anti-corrosion layer peeling clamp 33 with the end of the peeled anti-corrosion layer 4, and use the wing nut 36 to fix the flat head bolt 37 that passes through the anti-corrosion layer peeling clamp 33 to ensure that the anti-corrosion layer 4 is clamped by the anti-corrosion layer peeling clamp 33. S3) Parameter setting: Input the diameter of the pipeline 3 to be inspected, the material of the anti-corrosion layer 4 and other basic information into the control terminal 1; S4) Loading detection: While the start control terminal 1 controls the drive servo motor 22 through the integrated circuit board 30 to drive the drive wheel 27 to move at a constant speed along the steel guide rail 8, the start control terminal 1 drives the servo motor 22 through the integrated circuit board 30 to pull the transmission rope 23, thereby causing the anti-corrosion layer peeling clamp 33 of the quick clamping unit to peel off the cut anti-corrosion layer 4 at a constant speed. The tension sensor 24 collects the tension in real time and transmits it to the integrated circuit board 30. S5) Data output: The integrated circuit board 30 automatically calculates the average tensile force, i.e. the average adhesive force, and the tensile-displacement curve, and displays the results through the LCD screen embedded in the control terminal 1.
