Description

Technical Field

[0001] The present invention relates to the technical field of corrosion resistance detection, in particular to a plastic pipe corrosion resistance detection device. Background Art

[0002] The plastic pipe corrosion resistance testing device is a special device used to evaluate the performance of plastic pipes in corrosive environments. The device simulates actual use conditions and exposes plastic pipe samples to corrosive media such as acids, alkalis, and salts at different concentrations to test their resistance to chemical corrosion. During the test, the device monitors key indicators such as changes in the pipe's appearance, weight loss, and mechanical properties in real time to ensure accurate and reliable data. The device is usually made of corrosion-resistant materials and is equipped with a constant temperature control system and a stirring device to maintain a stable testing environment. The test results can be used to guide the selection of materials, process improvements, and quality control of plastic pipes, and are widely used in chemical, municipal, and construction industries. The device is easy to operate and has a high degree of automation. It can efficiently complete the testing of large quantities of samples and provide a scientific basis for the safe use of plastic pipes. The material selection of existing pipes is also diverse, such as high-density polyethylene pipes, polyvinyl chloride pipes, polypropylene pipes, as well as nano-composite pipes such as nano-silica and graphene that improve strength and antibacterial properties, and bio-based plastic pipes made of degradable materials such as polylactic acid for temporary projects. With the emergence of new pipes, different new pipes also need to be tested for corrosion resistance so that these pipes can be applied to their appropriate fields based on their material properties and corrosion resistance.

[0003] When conducting corrosion resistance testing on plastic pipes, the plastic pipes need to be fixed first. However, when testing the same batch of pipes, sampling testing is generally used to test the same batch of plastic pipes. Therefore, when testing the corrosion resistance of plastic pipes, different pipes of different sizes, batches, diameters and lengths are usually tested. However, after the pipe size changes greatly, manual debugging is required before the pipe is fixed before testing to ensure the subsequent testing effect of the pipe. However, manual debugging of the pipe fixation reduces the continuity of the pipe from loading to testing to returning the material, which relatively reduces the efficiency of the plastic pipe in corrosion resistance testing. In addition, manual debugging of the pipe is also prone to corrosive solutions corroding the staff, which poses certain risks.

[0004] Based on this, the present invention discloses a plastic pipe corrosion resistance detection device. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] When testing the corrosion resistance of the inner walls of existing plastic pipes, plastic pipes of different lengths and diameters need to be fixed first, and then a corrosive solution is sprayed inside the pipes. Finally, a detection probe, such as an infrared detection probe, is used to scan the inside of the pipe wall to judge the overall corrosion resistance of the plastic pipe based on the wall thickness, light transmittance, etc. However, each time a plastic pipe of a different length or diameter is replaced, the fixings for fixing the plastic pipe need to be adjusted, and it is impossible to adapt to various types of plastic pipes for positioning detection, resulting in limited detection efficiency.

[0021] In order to improve the detection efficiency of plastic pipes, the positioning component 3 is used to fix the two ends of plastic pipes of different lengths and to transport the fixed plastic pipes at the same time. Therefore, it is necessary to set a driving component 2 and a positioning component 3 in the entire detection box 1.

[0022] For this purpose, the present invention provides a plastic pipe corrosion resistance detection device, see Figure 12-13As shown, in order to achieve continuity in conveying and fixing plastic pipes, the positioning assembly 3 can be driven by the driving assembly 2. While the positioning assembly 3 that fixes the plastic pipe is moved, the plastic pipes of different lengths can be fixed by the positioning assembly 3. A turntable 24 is provided above the deceleration assembly, and the bottom of the positioning assembly 3 is installed on the top surface of the turntable 24. The inner surface of the detection box 1 is fixedly connected with a protrusion 29. The driving assembly 2 includes a deceleration assembly, which is composed of a motor, a pinion and a large gear. The output shaft of the motor is connected to the pinion, and the pinion is meshed with the large gear, and the top of the large gear is connected to the bottom of the turntable 24; the driving assembly 2 includes a deceleration assembly, and a turntable 24 is provided above the deceleration assembly. The bottom of the positioning assembly 3 is installed on the top surface of the turntable 24, the inner surface of the detection box 1 is fixedly connected with a protrusion 29, and the top surface of the turntable 24 is provided with a detection firmware 25. The positioning assembly 3 includes a positioning platform 31, the bottom surface of which is fixedly connected to the top surface of the turntable 24. An elastic telescopic rod 33 is slidably connected to the inner side of the positioning platform 31. The bottom of the elastic telescopic rod 33 is fixedly connected to the arc block 32. A connecting rod 35 is inserted into and hingedly connected to the inner side of the arc block 32. The end of the connecting rod 35 away from the arc block 32 is hingedly connected to a positioning disk 36. There are two sets of connecting rods 35, each symmetrically arranged around the centerline of the arc block 32. The initial state of the connecting rods 35 is such that the end closest to the arc block 32 is lower and the end closest to the positioning disk 36 is higher. Six sets of sealing rubber sheets 37 are fixedly connected to the center of the positioning disk 36. A connecting block 38 is fixedly connected to the side of the positioning disk 36. An elastic telescopic rod 39 is fixedly connected to the surface of the connecting block 38. A fixed column 310 is connected to the surface of the positioning platform 31. The elastic telescopic rod 39 is inserted into and slidably connected to the fixed column 310.

[0023] When working, the servo motor is started to drive the reduction gear to rotate, and the reduction gear drives the large gear to rotate, so that the large gear drives the entire turntable 24 and the positioning platform 31 on the top of the turntable 24 to rotate synchronously. When the positioning platform 31 rotates to the position of the protrusion 29, the top of the protrusion 29 will contact the arc surface at the bottom of the arc block 32, and because the elastic telescopic rod 33 on the top surface of the arc block 32 is inserted into the positioning platform 31 and slidably connected, the arc block 32 will rise stably when it is contacted by the protrusion 29, thereby pushing the two ends of the connecting rod 35 hinged to the arc block 32 to gradually rotate, but the length of the connecting rod 35 remains unchanged while the angle gradually becomes smaller. The symmetrical positioning plates 36 will gradually be stretched open to allow enough space in the positioning platform 31 to place plastic tubes of different lengths, so that each group of positioning platforms 31 can automatically unfold the symmetrical positioning plates 36 once it moves to the front of the loading channel 7. The loading and unloading components include loading and unloading brackets, and the surface of the loading and unloading brackets is provided with a cylinder. The output end of the cylinder is fixedly connected to a robotic arm, so that after the robotic arm grabs the plastic tube, the cylinder 1 pushes the robotic arm to place the grabbed plastic tube on the positioning platform 31. When the turntable 24 continues to rotate, the protrusion 29 no longer conflicts with the arc block 32, and the elastic telescopic rod 2 39 will pull back the positioning plate 36 and gradually approach the two ends of the plastic tube.

[0024] For details, see Figure 1-5 As shown, after achieving the continuity of plastic pipe feeding, the two ends of the plastic pipe need to be sealed and fixed, wherein the surface of the positioning plate 36 away from the positioning platform 31 is fixedly connected to the elastic telescopic rod three 312, the inner side of the positioning plate 36 is penetrated and slidably connected to the L-shaped plate 314, the inner side of the L-shaped plate 314 is provided with a resistance groove 315, the surface of the L-shaped plate 314 is fixedly connected to the positioning plate 316, the surface of the positioning plate 36 is fixedly connected to the cover 317, and the surface of the cover 317 is provided with a limiting groove 318; the elastic telescopic rod three 312 passes through the L-shaped plate 314 and is slidably connected, and the bottom of the positioning platform 31 is provided with a ball 319, and the ball 319 is located on the inner side of the annular groove 6.

[0025] During operation, when the positioning platform 31 rotates a certain distance and makes the positioning plate 36 close to the two ends of the plastic tube, the positioning plate 36 will drive the positioning plate 316 through the L-shaped plate 314 to gradually contact and seal the two ends of the plastic tube. Then, the spray gun is pushed by the electric push rod to insert the nozzle of the spray gun into the sealing film 37 to spray the corrosive solution on the inner wall of the plastic tube. Then, the spray gun is pulled back by the electric push rod. As the turntable 24 continues to rotate, when the positioning platform 31 moves to the position of the detection probe, the detection probe can be pushed by the electric push rod to insert into the sealing film 37 to detect the inside of the plastic tube.

[0026] For further information, see Figure 6-8As shown, in order to ensure stability during testing of plastic pipes of different diameters after positioning plastic pipes of different lengths, an adaptive fixing assembly 4 is used to fix plastic pipes of different diameters. The adaptive fixing assembly 4 includes a guide slot 419 provided on the surface of the positioning plate 316. A slider 42 is slidably connected to the inner side of the guide slot 419. An elastic telescopic rod 41 is fixedly connected to the surface of the slider 42. A turntable 45 is rotatably connected to the interior of the positioning plate 36. A toggle slot 46 is provided on the surface of the turntable 45. The elastic telescopic rod 41 is positioned in the groove 318 and inserted into the toggle slot 46. A contact block 47 is fixedly connected to the side of the turntable 45 and inserted into the inner side of the contact slot 315.

[0027] During operation, after the positioning plate 316 gradually contacts the two ends of the plastic tube, the positioning plate 316 will be subjected to the reaction force and push the L-shaped plate 314, so that the L-shaped plate 314 will not only compress the elastic telescopic rod three 312, but also the interference groove 315 opened on the surface of the L-shaped plate 314 will gradually contact the interference block 47, thereby forcing the interference block 47 to toggle the turntable 45 to rotate. When the turntable 45 rotates, the toggle groove 46 opened on its surface will toggle the elastic telescopic rod four 41 to slide, but the elastic telescopic rod four 41 is simultaneously inserted into the limiting groove 318, so that the elastic telescopic rod four 41 will slide in the limiting groove 318 after being toggled, and the slider 42 will slide in the guide groove 419 through the elastic telescopic rod four 41, so that the six groups of arc blocks 48 arranged in a circular array will gradually approach the outer wall of the plastic tube, thereby adapting to plastic tubes of different diameters.

[0028] Among them, see Figure 9-11 As shown, in order to adapt to plastic pipes of different diameters while improving the stability when fixing the plastic pipe, it is necessary to use the locking block 49 in the adaptive fixing component 4 to adapt to plastic pipes of different diameters while reinforcing the plastic pipe, wherein the surface of the slider 42 is fixedly connected to the surface of the arc block 48, and the left and right sides of the arc block 48 are hinged with locking blocks 49, and a torsion spring 410 is fixedly connected between the locking block 49 and the arc block 48; the inner side of the arc block 48 is fixedly connected to the fixing block 417, and the fixing block 417 is inserted into the arc groove on the surface of the arc groove rod 415; the outer side of the arc groove rod 415 is provided with a spring 416, one end of the spring 416 is fixedly connected to the surface of the arc groove rod 415, and the other end of the spring 416 is fixedly connected to the top surface of the arc block 48. One end of the rotating rod 414 located on the inner side of the linkage block 413 passes through and is fixedly connected to the winding wheel 418, and a pull rope 420 is fixed and wound on the surface of the winding wheel 418; the pull rope 420 passes through the linkage block 413, and the end of the pull rope 420 away from the winding wheel 418 is sleeved on the cross bar 412 and fixedly connected to the cross bar 412.

[0029] When the cam 418 is in contact with the outer wall of the plastic tube, the locking block 49 on both sides of the cam 418 is tightened by the pull rope 420 to lock the outer wall of the plastic tube. After the cam 418 is in contact with the outer wall of the plastic tube, the locking block 49 on both sides of the cam 418 is tightened, thereby improving the stability of the plastic tube when it is fixed. In the process of pulling the locking block 49, the pull rope 420 will be embedded in the take-up groove 411, and the pull rope 420 will not prevent the locking block 49 from fitting with the outer wall of the plastic tube.

[0030] In summary, the problem that the existing detection device needs to adjust the fixture to adapt to plastic pipes of different lengths and different diameters is effectively solved.

[0031] Working principle: By starting the servo motor in the drive component 2, the rotation of the entire turntable 24 can be achieved through components such as the reduction gear. While the turntable 24 rotates, the convex block 29 is cooperated to realize that when the positioning platform 31 on the turntable 24 moves to the position of the feeding channel 7, the positioning disks 36 on both sides of the positioning platform 31 can be automatically unfolded. After the turntable 24 rotates and drives the positioning platform 31 away from the convex block 29, the positioning disk 36 can drive the positioning plate 316 through the L-shaped plate 314 to automatically adapt to plastic pipes of different lengths, thereby ensuring the continuity of feeding and improving the efficiency of subsequent inspection. After the positioning disc 36 drives the positioning plate 316 to fix the two ends of the plastic tube, the adaptive fixing component 4 can be used to adapt to plastic tubes of different diameters for fixation, without the need to manually adjust the clamps to adapt to plastic tubes of different sizes. At the same time, when fixing plastic tubes of different diameters, the curvature between the entire plastic tube and the clamp is also different. When the linkage block 413 is retracted into the arc block 48, the locking block 49 hinged to the arc block 48 can be pulled to fit the surface of the plastic tube. While adapting to plastic tubes of different diameters for fixation, it can also ensure that the stability of the adaptive fixation is improved.
