Description

Technical Field

[0001] The present invention relates to the technical field of MPP pipe compressive strength testing, specifically an MPP pipe compressive property testing system based on artificial intelligence. Background Art

[0002] MPP pipes, namely modified polypropylene pipes, are a new type of plastic pipe with many excellent properties. MPP pipes have high strength and stiffness, can withstand large external pressures and tensile forces, are suitable for various complex construction environments, and can also resist the erosion of various chemical substances.

[0003] In the Chinese patent with the application number 2022112505016, specifically a graphene composite antistatic pipe compressive capacity testing device, when pressure testing a round pipe placed on two supporting mechanisms, the lower pressing plate moves downward to apply a downward pressure on the round pipe on the supporting mechanism directly below through two lower pressing wheels. According to the magnitude of the downward pressure of the telescopic cylinder and the deformation degree of the round pipe, the compressive capacity of the round pipe can be understood; and when the lower pressing plate moves downward to drive the two lower pressing wheels to press the part of the round pipe between the two supporting mechanisms, the round pipe will bend after being pressed. According to the magnitude of the downward pressure of the telescopic cylinder and the bending degree of the round pipe, the bending stiffness of the round pipe can be understood.

[0004] However, during the specific use of the above device, although it conducts local compressive testing on the pipe, during the specific operation, the inner side wall of the pipe is not effectively supported. If the support of the inner side wall is ignored, the measured compressive capacity will be lower than the actual situation, misleading the quality assessment of the pipe. And when an external pressure acts on the pipe without inner side wall support, the pipe structure is more likely to be damaged, such as serious problems like cracks and ruptures, resulting in inaccurate compressive test results.

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

[0006] The purpose of the present invention is to provide an MPP pipe compressive property testing system based on artificial intelligence to solve the problems mentioned in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: An MPP pipe compressive property testing system based on artificial intelligence, including an operation table, on both sides of the operation table, a side table one and a side table two are respectively fixedly installed. On the top of the side table one, a material blocking mechanism is fixedly installed. On the top of the side table two, an extrusion mechanism is fixedly installed. On the top of the operation table, a bearing cylinder is fixedly installed. An installation groove is opened at the top of the bearing cylinder. A material supporting mechanism is arranged outside the bearing cylinder;

[0008] A plurality of first guide plate groups and second guide plate groups are fixedly installed on the outer side wall of the bearing cylinder. The first guide plate groups and the second guide plate groups are arranged at equal intervals. Upper guide grooves and lower guide grooves are respectively formed in the side walls of the first guide plate groups and the second guide plate groups.

[0009] Furthermore, guide rails matching the number of the first guide plate groups and the second guide plate groups are fixedly installed on the side wall of the bearing cylinder. The guide rails are located between the correspondingly arranged first guide plate groups and second guide plate groups.

[0010] The material supporting mechanism includes an I-shaped slider and a pushing seat. The I-shaped slider is slidably connected in the correspondingly arranged guide rail, and the pushing seat is fixedly connected to the side wall of the I-shaped slider.

[0011] Furthermore, a positioning cylinder is fixedly installed inside the pushing seat. Two positioning grooves and a through groove are respectively formed on the outer side of the positioning cylinder. A top block is slidably connected inside the positioning cylinder. One end of the top block is slidably connected in the through groove, and a directional block is slidably connected in the positioning groove.

[0012] One end of the directional block is fixedly connected to the side wall of the top block, and the other end of the directional block is slidably connected in the correspondingly arranged upper guide groove and lower guide groove.

[0013] Furthermore, an upper expansion plate and a lower expansion plate are arranged outside the first guide plate groups and the second guide plate groups. The upper expansion plate and the lower expansion plate are respectively fixedly connected to the correspondingly arranged top blocks.

[0014] Furthermore, a first electric push rod is fixedly installed inside the installation groove, and a second electric push rod is fixedly installed inside the operation table. The top ends of the first electric push rod and the second electric push rod are respectively fixedly installed with a first push plate and a second push plate through bolts. A plurality of lower pull rods are fixedly connected to the bottom of the first push plate, and a plurality of upper pull rods are fixedly connected to the top of the second push plate. The ends of the lower pull rods and the upper pull rods are respectively fixedly connected to the side wall of the correspondingly arranged pushing seat.

[0015] Furthermore, the material blocking mechanism includes a first housing and a plurality of first electric push cylinders. The first housing is fixedly installed on the top of the first side table. The first electric push cylinders are installed inside the first housing. A baffle is arranged outside the first housing. The output end of the first electric push cylinder is fixedly connected to the side wall of the baffle.

[0016] Furthermore, the extrusion mechanism includes a second housing and a plurality of second electric push cylinders. The second housing is fixedly installed on the top of the second side table. The second electric push cylinders are fixedly installed inside the second housing. An extrusion plate is arranged outside the second housing. The output end of the second electric push cylinder is fixedly connected to the side wall of the extrusion plate. A slot hole is formed in the top of the operation table.

[0019] During the actual use of the present invention, through a series of structures such as a material supporting mechanism, the upper expansion plate and the lower expansion plate can be closely attached to each other without any gap, achieving comprehensive and stable support for the pipeline. At the same time, in the entire support system, only the part to be subjected to the compressive test is retained, that is, the position not supported by the upper expansion plate and the lower expansion plate. In this way, the local compressive test of the MPP pipe can be accurately realized, that is, the compressive capacity of the MPP pipe at a specific part can be more accurately evaluated, avoiding defects such as excessive damage that may be caused by a comprehensive extrusion test, difficulty in locating weak links, and covering up potential quality problems. Moreover, the comprehensive support achieved by the close fitting of the upper expansion plate and the lower expansion plate provides stable basic conditions for the local compressive test, ensuring the accuracy and reliability of the test.

Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: As Figures 1-7 shown, the MPP pipe compressive performance testing system based on artificial intelligence includes an operating table 1. A control panel (not shown in the figure) is further provided outside the operating table 1. A first side table 201 and a second side table 202 are respectively fixedly installed on both sides of the operating table 1. A material blocking mechanism 3 is fixedly installed on the top of the first side table 201;

[0031] In the actual operation process of the present invention, the material blocking mechanism 3 is used to support the MMP pipes sleeved outside the upper expanding plate 107 and the lower expanding plate 108. An extrusion mechanism 4 is fixedly installed on the top of the second side table 202. The extrusion mechanism 4 is used to perform extrusion tests on the MPP pipes. A bearing cylinder 5 is fixedly installed on the top of the operating table 1. An installation groove 601 is opened at the top of the bearing cylinder 5. A material supporting mechanism 10 is arranged outside the bearing cylinder 5;

[0032] A plurality of first guide plate groups 801 and second guide plate groups 802 are fixedly installed on the outer side wall of the bearing cylinder 5. The first guide plate groups 801 and the second guide plate groups 802 are arranged at equal intervals. Upper guide grooves 701 and lower guide grooves 702 are respectively opened on the side walls of the first guide plate groups 801 and the second guide plate groups 802. An upper expanding plate 107 and a lower expanding plate 108 are arranged outside the first guide plate groups 801 and the second guide plate groups 802. The upper expanding plate 107 and the lower expanding plate 108 are respectively fixedly connected to the corresponding top blocks 105.

[0033] It should be noted here that the sizes of the upper expansion plate 107 and the lower expansion plate 108 are processed adaptively according to the inner diameter of the MPP pipe to be detected currently. When detecting MPP pipes with different inner diameters, the corresponding upper expansion plate 107 and lower expansion plate 108 can be replaced to achieve tight fitting of the MPP pipe. When the upper expansion plate 107 and the lower expansion plate 108 move to the same horizontal height, the upper expansion plate 107 and the lower expansion plate 108 are in close contact with each other without gaps;

[0034] The side wall of the bearing cylinder 5 is fixedly installed with guide rails 9 that match the number of the first guide plate group 801 and the second guide plate group 802. The guide rails 9 are located between the correspondingly arranged first guide plate group 801 and the second guide plate group 802. The material supporting mechanism 10 includes an I-shaped slider 101 and a pushing seat 102. The I-shaped slider 101 is slidably connected in the correspondingly arranged guide rail 9. The pushing seat 102 is fixedly connected to the side wall of the I-shaped slider 101. A positioning cylinder 103 is fixedly installed inside the pushing seat 102. Two positioning grooves 104 and a through groove are respectively formed on the outer side of the positioning cylinder 103. A top block 105 is slidably connected inside the positioning cylinder 103. One end of the top block 105 is slidably connected in the through groove. A directional block 106 is slidably connected in the positioning groove 104;

[0035] One end of the directional block 106 is fixedly connected to the side wall of the top block 105. The other end of the directional block 106 is slidably connected in the correspondingly arranged upper guide groove 701 and lower guide groove 702. It should be noted here that both the upper guide groove 701 and the lower guide groove 702 are composed of two vertical straight grooves and an inclined groove, and the two straight grooves are connected end to end with the inclined groove;

[0036] An electric push rod 111 is fixedly installed inside the installation groove 601. An electric push rod 112 is fixedly installed inside the operating table 1. The top ends of the electric push rod 111 and the electric push rod 112 are respectively fixedly installed with a push plate 113 and a push plate 114 through bolts. A plurality of lower pull rods 115 are fixedly connected to the bottom of the push plate 113. A plurality of upper pull rods 116 are fixedly connected to the top of the push plate 114. The ends of the lower pull rods 115 and the upper pull rods 116 are fixedly connected to the side wall of the correspondingly arranged pushing seat 102.

[0037] During specific setting, 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 111 and the electric push rod 112 are immediately started;

[0038] A series of movement processes brought about after the operation of the electric push rod 111 are as follows:

[0039] The electric push rod 111 drives the lower pull rod 115 to move downward through the first push plate 113. 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. The orientation block 106 slides from the straight groove to the inclined groove. During this process, the orientation block 106 drives the top block 105 to slide in the through groove until the orientation block 106 slides from the inclined groove to another straight groove, and the orientation 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;

[0040] The following is a series of movement processes brought about after the operation of the electric push rod 112:

[0041] The electric push rod 112 drives the upper pull rod 116 to move upward through the second push plate 114. It should be noted here that a slot for the upper pull rod 116 to slide is opened at the top of the operating table 1, and the upper pull rod 116 is slidably connected in the slot. The upper pull rod 116 drives the I-shaped slider 101 to slide upward in the guide rail 9 through the correspondingly connected push seat 102. The orientation block 106 slides from the straight groove to the inclined groove. During this process, the orientation block 106 drives the top block 105 to slide in the through groove until the orientation block 106 slides from the inclined groove to another straight groove, and the orientation 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;

[0042] Under the mutual operation of structures such as the electric push rod 111 and the electric push rod 112, the upper expansion plate 107 and the lower expansion plate 108 are in the state as Figure 2 shown, and there is no gap between the upper expansion plate 107 and the lower expansion plate 108, and they are in full and tight contact with the inner wall of the MPP pipe. A relatively large gap between one upper expansion plate 107 and the other lower expansion plate 108 is used to perform extrusion testing on the MPP pipe at this side position;

[0043] Embodiment 2: The material blocking mechanism 3 includes a first housing 301 and multiple groups of first electric push cylinders 302. The first housing 301 is fixedly installed on the top of the first side table 201. The first electric push cylinders 302 are installed inside the first housing 301. A baffle 303 is arranged on the outside of the first housing 301. The output end of the first electric push cylinder 302 is fixedly connected to the side wall of the baffle 303.

[0044] The extrusion mechanism 4 includes a second housing 401 and multiple groups of second electric push cylinders 402. The second housing 401 is fixedly installed on the top of the second side table 202. The second electric push cylinders 402 are fixedly installed inside the second housing 401. An extrusion plate 403 is arranged on the outside of the second housing 401. The output end of the second electric push cylinder 402 is fixedly connected to the side wall of the extrusion plate 403;

[0045] A motorized lifting frame 12 is fixedly installed on the top of the operating platform 1. A high-definition camera 13 is fixedly installed at the bottom of the motorized lifting frame 12. The high-definition camera 13 records the contour change of the MPP pipe during the extrusion process in real time. Pressure sensors are arranged on the outer sides of the upper expanding plate 107 and the lower expanding plate 108. The pressure sensors are used to sense the pressure change of the contact surface with the MPP, so as to analyze the compressive performance test of the MPP pipe.

[0046] During specific setting, after the MPP pipe is tightened by the upper expanding plate 107 and the lower expanding plate 108, the motorized push cylinder 401 and the motorized push cylinder 402 are started at this time. The motorized push cylinder 401 pushes the baffle 303 to move until the baffle 303 contacts the MPP pipe and supports it. The motorized push cylinder 402 slowly pushes the extrusion plate 403. The extrusion plate 403 slowly extrudes the position of the MPP pipe that is not effectively supported by the upper expanding plate 107 or the lower expanding plate 108, causing the MPP pipe to deform, and uses the high-definition camera 13 and the pressure sensors to perform intelligent and local real-time analysis on the MPP pipe during the extrusion process;

[0047] After one side of the MPP pipe has been subjected to the extrusion test, in order to further expand the compressive performance test of the MPP, the extruded MPP pipe can be rotated so that the other unextruded surfaces of the MPP pipe rotate to the side close to the extrusion plate 403, and then the extrusion plate 403 extrudes it.

[0048] Performing a local extrusion test on the MPP pipe has the following important significance:

[0049] Detecting product defects in terms of quality control: It can be found that there may be defects in the MPP pipe during the production process, such as uneven materials, internal cavities, poor bonding, etc. The local extrusion test can simulate the local pressure conditions that the pipe may be subjected to during actual use. Those parts with quality problems are more likely to show abnormalities under the action of pressure, so they can be detected, which helps to promptly eliminate unqualified products before the product leaves the factory, improve the overall product quality, and reduce the later use risks and maintenance costs caused by quality problems.

[0050] Verifying the production process: By performing local extrusion tests on different batches of MPP pipes, the stability and consistency of the production process can be evaluated. If the performance of the pipes in different batches varies greatly during the test, it indicates that the production process may fluctuate and needs to be adjusted and optimized to ensure that each pipe produced can meet the design requirements and relevant standards, and improve the production management level of the enterprise.

[0051] Determining compressive capacity in terms of performance evaluation: MPP pipes may be subject to various external pressures in actual applications, such as soil pressure, traffic loads, etc. The local extrusion test can accurately measure the compressive capacity of the pipe under local pressure, providing an important basis for the design and selection of the pipe, helping engineers determine the safety factor of the pipe in a specific usage environment, reasonably plan the laying scheme of the pipe, and ensure the reliability and stability of the pipe system.

[0052] Evaluating deformation characteristics: During the test process, the deformation of the pipe under local extrusion can be observed, including the amount of deformation, deformation rate, etc. These data can be used to analyze mechanical property parameters such as the elastic modulus and yield strength of the pipe. Understanding the deformation characteristics of the pipe helps predict the behavior of the pipe in actual use, such as whether it will undergo excessive deformation under external forces and affect the normal function of the pipe.

[0053] Preventing accidents in terms of safety guarantee: Through the local extrusion test, the weak links of the pipe can be discovered in advance, and corresponding reinforcement measures or design improvements can be taken, thereby reducing the probability of accidents such as the pipe bursting and leaking due to being unable to withstand the pressure during use. Especially in some important engineering fields, such as electricity, communication, water supply and drainage, the safe operation of the pipe is crucial. The local extrusion test provides a strong guarantee for the safety of the project.
