Description

Technical Field

[0001] The present invention relates to the technical field of steel wire mesh skeleton pipe detection, in particular to a detection device for a reinforced PE steel wire mesh skeleton polyethylene pipe. Background Art

[0002] Polyethylene (PE) steel wire mesh composite pipes are widely used in municipal water supply and drainage, petrochemicals, gas transmission, and other fields due to their excellent corrosion resistance, impact resistance, and long service life. As reinforced structural pipes, the integrity of their internal steel wire mesh skeleton and the stability of the pipe wall structure directly affect the pipeline's pressure-bearing capacity and safety performance. However, in actual applications, such pipes are often tested by multiple complex working conditions such as geological subsidence, mechanical vibration, and chemical corrosion. Performance testing under a single working condition can no longer meet the comprehensive requirements of project acceptance, and there is an urgent need to develop detection devices that can simulate comprehensive environmental impacts.

[0003] At present, traditional testing methods are mostly focused on the verification of a single performance indicator. For example, air tightness testing usually adopts the static pressurization method, which can only reflect the sealing performance of the pipe under ideal conditions and cannot simulate the leakage risk under dynamic loads such as pipe bending and vibration. For corrosion resistance testing, conventional methods are mostly immersion tests or local spraying, which make it difficult to achieve uniform corrosion environment simulation and real-time damage monitoring. In addition, the functional integration of existing testing equipment is low, and mechanical strength testing, ultrasonic flaw detection and other links often require step-by-step operations, resulting in low detection efficiency and many human interference factors. In particular, for the structural damage of the wire mesh inside the reinforced PE pipe, there is a lack of dynamic flaw detection methods under complex working conditions, making it difficult to accurately evaluate the comprehensive performance degradation law of the pipe.

[0040] The mounting assembly 7 includes an electric slider 701 slidably connected to the bottom surface of the upper end of the bracket body 201. A third electric telescopic rod 702 is fixedly mounted on the bottom surface of the electric slider 701.

The outer wall of the mounting block 703 is fixedly connected to a plurality of first springs 704.

[0041] The clamping assembly 8 includes a vibration plate 801 fixedly connected to the ends of multiple first springs 704. Multiple fourth electric telescopic rods 802 are fixedly mounted on the outer wall of the vibration plate 801. The ends of the multiple fourth electric telescopic rods 802 are respectively fixedly connected to the second springs 808. The ends of the multiple second springs 808 are fixedly connected to a clamping plate 813. An air intake pipe 814 is fixedly connected to the middle position of one of the clamping plates 813 in the two sets of clamping assemblies 8. A vibration assembly 11 is further provided below the vibration plate 801 in the interior of the liquid collecting tank 3 to drive the vibration plate 801 to move up and down. The vibration assembly 11 includes a cam 1104 that presses the bottom surface of the vibration plate 801.

[0042] The auxiliary component 5 includes two supporting platforms 501, and a fixing ring 505 is fixedly installed between the upper ends of the two supporting platforms 501. The fixing ring 505 is an arc-shaped structure with a central angle greater than 200 degrees. A rotating block 503 is slidably installed inside the fixing ring 505, and a driving ring 504 is fixedly installed on one end of the rotating block 503. The upper end surfaces of the two supporting platforms 501 are both equipped with a first gear 506 meshing with the driving ring 504. The rotating block 503 is driven to rotate by the meshing transmission between the first gear 506 and the driving ring 504. A liquid storage tank 507 is fixedly installed on the inner wall of the rotating block 503, and a plurality of nozzles 508 are fixedly installed on the liquid storage tank 507. Two symmetrically arranged second electric telescopic rods 509 are also fixedly installed on the inner wall of the rotating block 503. The ends of the two second electric telescopic rods 509 are both fixedly installed with arc blocks 510, and ultrasonic flaw detection instruments are respectively provided on the two arc blocks 510;

[0043] In this device, the electric slider 701 is used in conjunction with the second electric slide rail 204. The electric slider 701 is driven by electricity to slide on the bottom surface of the second electric slide rail 204. The two ends of the pipe 6 are clamped and fixed by two sets of clamping components 8. It can be used to detect the air tightness of the pipe 6. At the same time, in conjunction with other components such as the extrusion component 4, the auxiliary component 5 and the vibration component 11, it can simulate various usage conditions of the pipe 6 and then detect the air tightness of the pipe 6 under different usage conditions. After the end of the pipe 6 is blocked, air is supplied to the interior of the pipe 6 through the air inlet pipe 814. After continuously supplying air to the interior of the pipe 6, the air tightness of the pipe 6 can be detected. At the same time, the structural strength of the pipe 6 can be tested by squeezing the outer wall of the pipe 6 through the structure in the squeezing component 4, and the outer wall of the pipe 6 can be squeezed by the point-shaped squeezing head 405 and the strip-shaped squeezing head 408. In the absence of support below the pipe 6, when any position of the outer wall of the pipe 6 is squeezed, the squeezed area on the pipe 6 bends downward. At this time, the two sets of clamping components 8 can be used to simultaneously perform air tightness testing on the gas transmission inside the pipe 6 to simulate whether the geological subsidence in actual application affects the air tightness of the pipe 6. In this process, when any position of the outer wall of the pipe 6 is squeezed and the pipe 6 bends, the clamping components 8 provided at both ends of the pipe 6 are used to test the air tightness of the pipe 6. The output end of the fourth electric telescopic rod 802 extends to extrude the two ends of the pipe 6, and cooperates with the extrusion component 4 to keep the pipe 6 in a curved curvature. The second spring 808 provided at the end of the fourth electric telescopic rod 802 can be deformed synchronously when the pipe 6 bends, thereby avoiding irreversible deformation at the connection between the clamping plate 813 and the fourth electric telescopic rod 802. The cooperation of the extrusion component 4 and the two sets of clamping components 8 can simulate the detection of the air tightness of the pipe 6 when the pipe 6 is bent due to geological subsidence. The high-pressure micro-diaphragm pump and multiple nozzles 508 can also be used to spray the corrosive solution on the outer wall of the pipe 6, and the rotating block 503 can be rotated along the pipe 6 to maintain the pressure. Continuous rotation can spray the outer wall of the pipe 6 evenly. After the corrosive liquid is sprayed onto the outer wall of the pipe 6, the outer wall of the pipe 6 is left to stand for a period of time. The staff can observe and measure the outer wall of the pipe 6. The collecting tank 3 can collect the corrosive liquid. In this case, the air tightness test of the inside of the pipe 6 can also be carried out at the same time to observe the impact of the corrosive environment on the air tightness of the pipe 6 when it is used. The ultrasonic flaw detector arranged on the two arc blocks 510 can rotate synchronously with the rotating block 503, and can also slide along the outer wall of the pipe 6 with the supporting platform 501, and can be used to detect the internal structure of the pipe wall of the pipe 6 under various simulation conditions.

When the half-tooth 1102 continues to rotate, the tooth grooves opened on the outer wall of the half-tooth 1102 are separated from the multiple tooth blocks 1105 fixed on the outer wall of the cam 1104. Then, under the action of the cam 1104 and the gravity of the vibration plate 801 itself, the vibration plate 801 moves downward. Through the cooperation of the cam 1104 set under the two groups of clamping components 8, the two groups of clamping components 8 set at both ends of the pipe 6 can be made to move up and down alternately, thereby simulating the vibration of the pipe 6 during use.

[0051] As a technical optimization solution of the present invention, first electric slide rails 203 are fixedly installed at both ends of the base plate 1, and electric slide seats 202 are slidably installed on the upper surfaces of the two first electric slide rails 203, and the two ends of the bracket body 201 are respectively fixedly connected to the two electric slide seats 202; the electric slide seat 202 is driven by electricity to slide along the upper surface of the first electric slide rail 203, which can drive the bracket body 201 to slide and switch positions above the liquid collection tank 3.

[0052] As a technical optimization solution of the present invention, a lifter 9 is fixedly installed on the other side of the upper surface of the base plate 1, and a placement table 10 is fixedly installed on the upper end of the lifter 9. The PE steel wire mesh skeleton polyethylene pipe to be tested is placed on the upper surface of the placement table 10. The upper surface of the placement table 10 is an inwardly concave arc setting. The placement table 10 and the pipe 6 placed on the upper end surface of the placement table 10 can be lifted upward by the lifter 9. At the same time, when the pipe 6 is placed on the upper surface of the placement table 10, it can cooperate with the extrusion component 4 to perform extrusion testing on the outer wall of the pipe 6.

[0053] When the present invention is in use, the PE steel wire mesh skeleton polyethylene pipe that needs to be tested is placed on the upper surface of the placement table 10. The upper surface of the placement table 10 is an inwardly concave arc setting. The placement table 10 and the pipe 6 placed on the upper end surface of the placement table 10 can be lifted upward by the elevator 9. Then, the electric slide 202 is driven by electricity to slide along the upper surface of the first electric slide rail 203. When the bracket body 201 moves to the top of the placement table 10, the third electric telescopic rod 702 is extended to move the clamping assembly 8 to the two ends of the pipe 6. Then, the electric slider 701 is driven by electricity to slide along the second electric slide rail 204. The two groups of clamping assemblies 8 are used to clamp the two ends of the pipe 6 respectively. Among them, the fastening cylinder 803 and the docking cylinder 806 in the clamping assembly 8 are combined to form an existing PE flange quick connector. When the end of the pipe 6 is inserted into the inside of the fastening cylinder 803, it can be stably connected to the clamping assembly 8. The end of the tube 6 is connected, wherein when the end of the tube 6 is inserted into the interior of the fastening cylinder 803, the user can extend the output end of the fifth electric telescopic rod 812 to push the push plate 811 to move, and then the push plate 811 pushes the rubber pad 810 to deform. The rubber pad 810 is made of elastic material. When the rubber pad 810 is deformed, it can be squeezed tightly with the inner wall of the end of the tube 6, thereby ensuring the sealing of the end of the tube 6. The outer wall of the clamping plate 813 in one group of clamping assemblies 8 is connected to the air inlet pipe 814, and then gas is injected into the interior of the tube 6 through the air inlet pipe 814 and the air supply channel 809 opened on the plug-in column 807. The end of the plug-in column 807 in the other group of clamping assemblies 8 is fixedly installed with a pressure sensor. After sealing the two ends of the tube 6, gas is supplied to the interior of the tube 6 through the air inlet pipe 814. After continuously supplying gas to the interior of the tube 6, the air tightness of the tube 6 can be detected by observing the data transmitted by the pressure sensor.

[0054] When the pipe 6 is placed on the upper surface of the placement table 10, the pipe 6 can be partially squeezed by the extrusion assembly 4. The rotating disk 402 in the extrusion assembly 4 is a prior art and can be driven to rotate by electricity. The point extrusion head 405 and the strip extrusion head 408 can be switched by rotating the rotating disk 402. The output ends of the first electric telescopic rods 404 in the two sets of circular frames 403 are extended to respectively use the point extrusion head 405 and the strip extrusion head 408 to squeeze the outer wall of the pipe 6. The outer wall of the pipe 6 can be subjected to point contact extrusion and strip contact extrusion with a larger contact area. After extrusion, the staff can observe and measure the outer wall of the pipe 6. The extrusion of the extrusion assembly 4 can be used to detect the strength of the pipe wall of the pipe 6.

[0055] By driving the bracket body 201 to slide horizontally, the pipe 6 is moved to the top of the liquid collecting box 3 through the cooperation of the two sets of installation components 7 and the two sets of clamping components 8. When the pipe 6 is moved to the top of the auxiliary component 5, the pipe 6 is moved by controlling the third electric telescopic rod 702 until the pipe 6 is located inside the fixed ring 505. Then, the outer wall of the pipe 6 is squeezed again by the point-shaped extrusion head 405 and the strip-shaped extrusion head 408. At this time, there is a lack of support below the pipe 6. When the outer wall of the pipe 6 is squeezed at any position, the squeezed area on the pipe 6 bends downward. At this time, the two sets of clamping components 8 can be cooperated to simultaneously perform air tightness testing on the gas supply inside the pipe 6 to simulate the actual application. In the case of geological subsidence during use, whether the air tightness of the pipe 6 is affected. In this process, when any position of the outer wall of the pipe 6 is squeezed, causing the pipe 6 to bend, the output ends of the fourth electric telescopic rod 802 arranged at both ends of the pipe 6 extend and squeeze the two ends of the pipe 6, and cooperate with the extrusion component 4 to make the pipe 6 maintain the curvature of the curvature. The second spring 808 arranged at the end of the fourth electric telescopic rod 802 can be deformed synchronously when the pipe 6 bends, avoiding irreversible deformation at the connection between the clamping plate 813 and the fourth electric telescopic rod 802. The cooperation between the extrusion component 4 and the two sets of clamping components 8 can simulate the test of the air tightness of the pipe 6 when the pipe 6 is bent due to geological subsidence;

[0056] When the pipe 6 is clamped and moved to the top of the liquid collecting box 3 and adjusted to a suitable position, the vibration component 11 arranged inside the liquid collecting box 3 is below the vibration plate 801. The two cams 1104 in the two groups of vibration components 11 alternately swing to drive the vibration plates 801 connected to the two ends of the pipe 6 to move. By adjusting the swing frequency of the two cams 1104, when the two cams 1104 simultaneously push the two vibration plates 801 upward, the pipe 6 can simulate the situation where both ends shake upward or downward at the same time. When the two cams 1104 alternately push the two vibration plates 801 upward, the two ends of the pipe 6 alternately move upward, which can simulate the situation where the two ends of the pipe 6 swing. Both vibration conditions of the pipe 6 can be coordinated with the air tightness detection of the pipe 6 to detect the air tightness of the pipe 6 when it is vibrated in actual application.

[0057] Driven by an external motor, the two threaded rods 502 can rotate, and the two supporting platforms 501 are respectively threadedly connected to the two threaded rods 502, and the outer wall of the supporting platform 501 is slidably connected to the inner wall of the liquid collecting tank 3. Then, the two supporting platforms 501 can drive the fixed ring 505 and the rotating block 503 installed inside the fixed ring 505 to slide inside the liquid collecting tank 3. Among them, the two first gears 506 are externally connected to the motor. After the motor is powered on, the two first gears 506 can be driven to rotate. The two first gears 506 are meshed with the driving ring 504. Under the action of the two first gears 506, the rotating block 503 fixedly connected to the driving ring 504 can rotate along the inner wall of the fixed ring 505. A storage The liquid tank 507 is filled with a solution for corrosive testing of the pipe 6, such as a sodium chloride solution or a sodium hydroxide solution and a hydrochloric acid mixture. A high-pressure micro-diaphragm pump is provided inside the liquid tank 507. After the high-pressure pump is turned on, the corrosive solution can be sprayed onto the outer wall of the pipe 6 through multiple nozzles 508, and the rotating block 503 continuously rotates along the pipe 6 to spray the outer wall of the pipe 6 evenly. After the corrosive liquid is sprayed onto the outer wall of the pipe 6, the outer wall of the pipe 6 is allowed to stand for a period of time, and then the staff can observe and measure the outer wall of the pipe 6. In this case, the air tightness test of the inside of the pipe 6 can also be carried out at the same time to observe the impact of the corrosive environment on the air tightness of the pipe 6 when it is used;

[0058] The user drives the rotating disk 402 to rotate and adjust the drill bit 407 to be just above the pipe 6, and drives the drill bit 407 to rotate by the first servo motor 406 to drill the surface of the pipe 6. During this process, the air tightness test of the pipe 6 is carried out simultaneously. When the interior of the pipe 6 is under high pressure, when the outer wall of the pipe 6 is damaged and cracks appear, gas overflows outward through the gap. At this time, the ultrasonic flaw detection instrument (model: Zhongyi Boteng SUB100) transmitter and receiver arranged on the two arc blocks 510 arranged inside the rotating block 503 can perform ultrasonic testing on the entire wall of the pipe 6. Through ultrasonic testing, the damage to the wall of the pipe 6 caused by the overflow of high-pressure gas due to the appearance of pores in the pipe 6 can be observed. This can be used to detect the strength of the steel wire mesh skeleton inside the reinforced PE steel wire mesh skeleton polyethylene pipe. If the pores on the wall of the pipe 6 are severely damaged, it means that the pipeline does not meet the production standards of the reinforced PE steel wire mesh skeleton polyethylene pipe.

[0059] The ultrasonic flaw detectors arranged on the two arc-shaped blocks 510 can rotate synchronously with the rotating block 503 and can also slide along the outer wall of the pipe 6 with the supporting platform 501, so as to detect the internal structure of the pipe wall of the pipe 6 in conjunction with other simulation situations.
