Description

Technical Field

[0001] The invention relates to the technical field of MPP pipe compression test, and in particular to an MPP pipe compression performance test system based on artificial intelligence. Background Art

[0002] MPP pipe, or modified polypropylene pipe, is a new type of plastic pipe with many excellent properties. MPP pipe has high strength and rigidity, can withstand greater external pressure and tension, is suitable for various complex construction environments, and can also resist erosion by a variety of chemical substances.

[0003] The Chinese patent with application number 2022112505016 is specifically a graphene composite anti-static tube compressive capacity testing device. When a pressure test is performed on a circular tube placed on two supporting mechanisms, the lower pressure plate moves downward to apply downward pressure to the circular tube on the supporting mechanism directly below through two lower pressure wheels. The compressive capacity of the circular tube can be understood according to the downward pressure of the telescopic cylinder and the degree of deformation of the circular tube; and the downward movement of the lower pressure plate drives the two lower pressure wheels to press down the part of the circular tube located between the two supporting mechanisms. The circular tube will bend after being compressed. The bending stiffness of the circular tube can be understood according to the downward pressure of the telescopic cylinder and the degree of bending of the circular tube.

[0004] However, during the actual use of the above-mentioned equipment, although a local compression test is performed on the pipe, the inner wall of the pipe is not effectively supported during the specific operation. If the inner wall support is ignored, the compression resistance obtained from the test will be lower than the actual situation, which will mislead the quality assessment of the pipe. In addition, when external pressure acts on the pipe without inner wall support, the pipe structure is more vulnerable to damage, such as cracks, ruptures and other serious problems, which will lead to inaccurate compression test results.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0011] Furthermore, an electric push rod 1 is fixedly installed inside the installation groove, and an electric push rod 2 is fixedly installed inside the operating table.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0018] Embodiment 1: Figure 1-Figure 7 As shown, the MPP pipe compression performance testing system based on artificial intelligence includes an operating table 1, a control panel (not shown in the figure) is also arranged on the outside of the operating table 1, a side table 1 201 and a side table 2 202 are fixedly installed on both sides of the operating table 1, and a material blocking mechanism 3 is fixedly installed on the top of the side table 1 201; In the actual operation of the present invention, the material blocking mechanism 3 is used to support the MMP pipes sleeved on the outer sides of the upper expansion plate 107 and the lower expansion plate 108, and the top of the side platform 202 is fixedly installed with an extrusion mechanism 4, which is used to perform an extrusion test on the MPP pipes. The top of the operating platform 1 is fixedly installed with a bearing cylinder 5, and the top of the bearing cylinder 5 is provided with a mounting groove 601, and the outer side of the bearing cylinder 5 is provided with a supporting mechanism 10; The outer side wall of the supporting tube 5 is fixedly mounted with a plurality of guide plate groups 1 801 and 802, which are arranged at equal intervals, and the side walls of the guide plate groups 1 801 and 802 are respectively provided with upper guide grooves 701 and lower guide grooves 702, and the outer sides of the guide plate groups 1 801 and 802 are provided with upper expansion plates 107 and lower expansion plates 108, which are respectively fixedly connected to the corresponding top blocks 105.

[0019] It should be explained here that the sizes of the upper expansion plate 107 and the lower expansion plate 108 are processed according to the inner diameter of the MPP pipe to be tested. When testing MPP pipes with different inner diameters, the upper expansion plate 107 and the lower expansion plate 108 can be replaced to achieve a close fit with the MPP pipe. When the upper expansion plate 107 and the lower expansion plate 108 are moved to the same horizontal height, the upper expansion plate 107 and the lower expansion plate 108 are fitted to each other without a gap. The side wall of the bearing cylinder 5 is fixedly installed with guide rails 9 matching the number of the guide plate group 1 801 and the guide plate group 2 802, and the guide rails 9 are located between the corresponding guide plate group 1 801 and the guide plate group 2 802. The supporting mechanism 10 includes an I-shaped slider 101 and a pushing seat 102. The I-shaped slider 101 is slidably connected in the corresponding guide rail 9, and the pushing seat 102 is fixedly connected to the side wall of the I-shaped slider 101. A positioning cylinder 103 is fixedly installed on the inner side of the pushing seat 102. Two positioning grooves 104 and a through groove are respectively provided on the outer side of the positioning cylinder 103. A top block 105 is slidably connected inside the positioning cylinder 103, and one end of the top block 105 is slidably connected in the through groove, and a directional block 106 is slidably connected in the positioning groove 104. One end of the orientation block 106 is fixedly connected to the side wall of the top block 105, and the other end of the orientation block 106 is slidably connected to the corresponding upper guide groove 701 and the lower guide groove 702. It should be explained here that the upper guide groove 701 and the lower guide groove 702 are composed of two vertical straight grooves and one inclined groove, and the two straight grooves are connected to the end of the inclined groove; An electric push rod 111 is fixedly installed inside the mounting groove 601, and an electric push rod 2 112 is fixedly installed inside the operating table 1. Push plates 113 and 114 are fixedly installed on the top of the electric push rod 111 and the top of the electric push rod 2 112 respectively by bolts. The bottom of the push plate 113 is fixedly connected to multiple groups of lower pull rods 115, and the top of the push plate 2 114 is fixedly connected to multiple groups of upper pull rods 116. The ends of the lower pull rods 115 and the upper pull rods 116 are fixedly connected to the corresponding side walls of the push seat 102.

[0020] When setting up specifically, after the MPP pipe is sleeved on the outer sides of the upper expansion plate 107 and the lower expansion plate 108, the electric push rod 1 111 and the electric push rod 2 112 are started immediately; The series of motion processes brought about by the operation of the electric push rod 111 are as follows: The electric push rod 111 drives the lower pull rod 115 to move downward through the push plate 113, and the lower pull rod 115 drives the I-shaped slider 101 to slide downward in the guide rail 9 through the correspondingly connected push seat 102, and the directional block 106 slides from the straight groove to the inclined groove. During this process, the directional block 106 drives the top block 105 to slide in the through groove until the directional block 106 slides from the inclined groove to another straight groove. The directional block 106 continues to slide in the straight groove until it can no longer slide and then stops. At this time, the top block 105 drives the upper expansion plate 107 to fully extend; The series of motion processes brought about by the operation of the electric push rod 112 are as follows: The second electric push rod 112 drives the upper pull rod 116 to move upward through the second push plate 114. It should be noted that a slot for the upper pull rod 116 to slide is provided on the top of the operating table 1. The upper pull rod 116 is slidably connected in the slot. The upper pull rod 116 drives the I-type slider 101 to slide upward in the guide rail 9 through the correspondingly connected pushing seat 102. The directional block 106 slides from the straight groove to the inclined groove. During this process, the directional block 106 drives the top block 105 to slide in the through groove until the directional block 106 slides from the inclined groove to another straight groove. The directional block 106 continues to slide in the straight groove until it can no longer slide and then stops. At this time, the top block 105 drives the lower expansion plate 108 to fully extend; Under the mutual operation of the electric push rod 111 and the electric push rod 2 112, the upper expansion plate 107 and the lower expansion plate 108 are in the following state. Figure 2 As shown, there is no gap between the upper expansion plate 107 and the lower expansion plate 108, and the inner wall of the MPP pipe is fully and tightly fitted. The larger gap between one upper expansion plate 107 and another lower expansion plate 108 is used for extrusion testing of the MPP pipe at that side; Embodiment 2: The material blocking mechanism 3 includes a cover shell 301 and multiple groups of electric push cylinders 302. The cover shell 301 is fixedly installed on the top of the side platform 201. The electric push cylinders 302 are installed inside the cover shell 301. A baffle 303 is provided on the outside of the cover shell 301. The output end of the electric push cylinder 302 is fixedly connected to the side wall of the baffle 303.

[0021] The extrusion mechanism 4 includes a second cover shell 401 and a plurality of second electric push cylinders 402. The second cover shell 401 is fixedly mounted on the top of the second side platform 202. The second electric push cylinders 402 are fixedly mounted inside the second cover shell 401. An extrusion plate 403 is arranged outside the second cover shell 401. The output end of the second electric push cylinder 402 is fixedly connected to the side wall of the extrusion plate 403. An electric lifting frame 12 is fixedly installed on the top of the operating table 1, and a high-definition camera 13 is fixedly installed on the bottom of the electric lifting frame 12. The high-definition camera 13 records the contour changes of the MPP pipe during the extrusion process in real time. Pressure sensors are arranged on the outer sides of the upper expansion plate 107 and the lower expansion plate 108. The pressure sensors are used to sense the pressure changes on the contact surface with the MPP, so as to analyze the compressive performance test of the MPP pipe.

[0022] In the specific setting, when the MPP pipe is pressed tightly by the upper expansion plate 107 and the lower expansion plate 108, the electric push cylinder 1 401 and the electric push cylinder 2 402 are started, the electric push cylinder 1 401 pushes the baffle 303 to move until the baffle 303 contacts and supports the MPP pipe, and the electric push cylinder 2 402 slowly pushes the extrusion plate 403, and the extrusion plate 403 slowly squeezes the position of the MPP pipe that is not effectively supported by the upper expansion plate 107 or the lower expansion plate 108, causing the MPP pipe to deform, and uses the high-definition camera 13 and the pressure sensor to perform intelligent, local real-time analysis of the MPP pipe during the extrusion process; After one side of the MPP pipe is subjected to the extrusion test, in order to further expand the compression resistance test of the MPP, the extruded MPP pipe can be rotated so that the other unextruded surface of the MPP pipe is rotated to the side close to the extrusion plate 403, and then the extrusion plate 403 extrudes it.

[0023] The local extrusion test of MPP pipe has the following important significance: Detect product defects in quality control: It can be found that the MPP pipeline may have defects such as uneven materials, internal voids, poor bonding, etc. in the production process. The local extrusion test can simulate the local pressure conditions that the pipeline may be subjected to in actual use. Those parts with quality problems are more likely to show abnormalities under pressure and thus be detected. This helps to eliminate defective products in time before the products leave the factory, improve the overall product quality, and reduce the later use risks and maintenance costs caused by quality problems.

[0024] Verify the production process: By conducting local extrusion tests on different batches of MPP pipes, the stability and consistency of the production process can be evaluated. If the performance of different batches of pipes in the test varies greatly, it means that the production process may fluctuate and needs to be adjusted and optimized to ensure that every pipe produced meets the design requirements and relevant standards, thereby improving the company's production management level.

[0025] Determine the compressive capacity in performance evaluation: In actual applications, MPP pipelines may be subject to various external pressures, such as soil pressure, traffic load, etc. The local extrusion test can accurately measure the compressive capacity of the pipeline under local pressure, providing an important basis for the design and selection of pipelines, helping engineers determine the safety factor of the pipeline in a specific use environment, and reasonably plan the pipeline laying plan to ensure the reliability and stability of the pipeline system.

[0026] Evaluation of deformation characteristics: During the test, the deformation of the pipeline when it is locally squeezed can be observed, including deformation amount, deformation rate, etc. These data can be used to analyze the elastic modulus, yield strength and other mechanical performance parameters of the pipeline. Understanding the deformation characteristics of the pipeline helps predict the behavior of the pipeline in actual use, such as whether excessive deformation will occur when subjected to external forces and affect the normal function of the pipeline.

[0027] Prevent accidents in terms of safety assurance: Through local extrusion testing, the weak links of the pipeline can be discovered in advance, and corresponding reinforcement measures or improved designs can be taken to reduce the probability of accidents such as rupture and leakage due to the pipeline being unable to withstand pressure during use. Especially in some important engineering fields, such as electricity, communications, water supply and drainage, the safe operation of pipelines is of vital importance, and local extrusion testing provides a strong guarantee for the safety of the project.
