Description
Technical Field
[0001] The invention belongs to the technical field of ABR pipe testing, and in particular relates to an ABR pipe performance testing device. Background Art
[0002] Pipes and fittings made of acrylate polymer blended with poly resin for water supply (ABR pipes for short) have excellent properties such as high pressure resistance, low temperature resistance and high external load, and are suitable for urban water supply networks and long-distance water transmission and diversion projects.
[0003] New ABR pipes require multiple tests before planning and use to assess their various performance and parameters, facilitating planning. Existing ABR pipe performance testing equipment only considers the instantaneous pressure applied to the pipe and is incapable of testing its compressive strength under sustained pressure. Furthermore, it is also incapable of testing the performance of ABR pipes under operating conditions. Summary of the Invention
[0004] In view of this, the present invention discloses an ABR pipe performance testing device, which aims to solve the problem that the existing ABR pipe performance testing device is not capable of testing the ABR pipe performance of the ABR pipe in a working state.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:
[0006] An ABR pipe performance testing device includes a workbench, wherein the workbench is provided with two coaxial slides, wherein slides are slidably connected in the slides, wherein a locking pin is detachably connected between the slides and the slides, and wherein a closing plate is provided on each of the slides; wherein a liquid storage tank is provided on the workbench, wherein a hose connected to the liquid storage tank is provided on each of the closing plates, and wherein a pump is provided on the liquid storage tank; wherein two supports for mounting ABR pipes are symmetrically arranged between the slides; wherein the workbench is provided with a continuous pressure structure for continuously applying pressure to the outer wall of the ABR pipe; wherein the workbench is provided with an instantaneous pressure structure for applying instantaneous pressure to the outer wall of the ABR pipe.
[0007] In this solution, the ABR pipe is fixed to a support, the slide is slid, the end of the ABR pipe is sealed with a closing plate, and the slide is locked with a locking pin. At this time, the ABR pipe forms a loop with the liquid storage tank through the hoses at both ends, and the liquid is circulated between the ABR pipe and the liquid storage tank by a pump. The ABR pipe is then continuously pressurized or instantaneously pressurized using a continuous pressure structure or an instantaneous pressure structure, respectively, to test the various pressure resistance of the ABR pipe in the working state. In addition, the ABR pipe can also be tested without liquid in it, thereby more comprehensively testing the performance of the ABR pipe.
[0008] Furthermore, the continuous pressure structure includes two mounting seats symmetrically fixed on the workbench, and the facing ends of the mounting seats are provided with hydraulic rods horizontally and perpendicular to the ABR pipe. The ends of the hydraulic rods are fixed with clamping plates whose ends are in contact with the outer wall of the ABR pipe. The facing end faces of the clamping plates are coaxially provided with mounting grooves, and rubber bags are fixed between the upper and lower sides of the mounting grooves. The rubber bags contain liquid, and the ends of the mounting grooves are provided with telescopic cylinders facing the rubber bags, and the ends of the telescopic cylinders are provided with push plates connected to the rubber bags; the facing ends of the mounting grooves are provided with semicircular grooves, and the grooves are concentric with the ABR pipes. Positioning screws passing through the clamping plates are horizontally threaded on both sides of the grooves, and the facing ends of the positioning screws are provided with baffles slidably connected to the arc surface of the grooves. The baffles are arc-shaped and coaxial with the clamping plates.
[0009] In this solution, once the ABR pipe is installed, the hydraulic rod is extended to align the clamping plate with the ABR pipe. Based on the required pressure area for the ABR pipe test, a corresponding number of baffles are selected. By rotating the positioning screws on the corresponding baffles, the baffles are moved away from the baffles facing them, exposing the corresponding area of the installation slot. Furthermore, the exposed area of the installation slot can be further adjusted by controlling the distance the baffles move. A hydraulic cylinder then pushes the baffles to squeeze the rubber bag, forcing it to tightly adhere to the ABR pipe through the exposed area of the installation slot and continuously applying pressure to the ABR pipe. The continuous pressure structure in this solution can apply continuous pressure to different pressure-bearing areas of the ABR pipe, allowing for more accurate testing of the ABR pipe's sustained pressure performance.
[0010] Furthermore, the instantaneous pressure structure includes a gantry, a moving block is arranged between the two sides of the gantry, and electromagnetic acceleration coils for accelerating the moving block are arranged on both sides of the gantry. A number of guide grooves that pass through the moving block horizontally and vertically are opened inside the moving block, and the guide grooves are parallel to the ABR pipes. Both ends of the guide grooves are slidably provided with tightening blocks, and the facing end faces of the tightening blocks are inclined. A number of through grooves are opened at the bottom of the guide grooves, and impact blocks are slidably connected in the through grooves, and elastic reset parts are provided between the impact blocks and the through grooves, and the bottoms of adjacent impact blocks are all abutted against each other.
[0011] In this solution, after the ABR pipe is installed, the corresponding number of abutment blocks at both ends of the guide groove are pushed according to the required pressure area for the ABR pipe test. The inclined end faces of the abutment blocks are used to squeeze the impact blocks, causing the corresponding impact blocks to move downward. The impact blocks that move downward to the limit position are used to apply instantaneous pressure to the ABR pipe, thereby controlling the contact area of the instantaneous pressure structure on the ABR pipe. In addition, by controlling the movement distance of the abutment blocks, the number of impact blocks that move downward is controlled, further increasing the contact area of the instantaneous pressure structure on the ABR pipe. The moving blocks are then released from a high position, allowing them to fall freely, and the impact blocks at the bottom of the moving blocks are used to apply an instantaneous force to the ABR pipe. In addition, the moving blocks are accelerated by electromagnetic acceleration coils on both sides of the gantry to increase the force applied to the ABR pipe. In this solution, the contact area between the instantaneous pressure structure and the ABR pipe is controlled by adjusting the number of impact blocks that move downward, thereby more accurately testing the sustained pressure performance of the ABR pipe.
[0012] Furthermore, the bottom of each impact block is in contact with the outer arc surface of the ABR pipe.
[0013] Furthermore, the adjustment grooves are provided with reinforcement grooves along the axis direction of the clamping plate, and the back sides of the baffles are provided with reinforcement ribs that slide in cooperation with the reinforcement grooves.
[0014] Furthermore, a rubber pad layer is provided on the surface of the baffle.
[0015] Furthermore, the movable block is detachably connected to a limiting pin for fixing the pressing block.
[0016] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] like Figures 1 to 5 As shown:
[0025] A performance testing device for an ABR pipe 22 includes a workbench 1. Two coaxial slides are provided on the workbench 1. Slides 2 are slidably connected in the slides. Locking pins (which are conventional technical means and therefore not shown in the figure) are detachably connected between the slides 2 and the slides. A closing plate 3 is provided on each of the slides 2. A liquid storage tank 4 is provided on the workbench 1. A hose 5 connected to the liquid storage tank 4 is provided on each of the closing plates 3. A pump and a temperature control device are provided on the liquid storage tank 4. Two supports 6 for mounting the ABR pipe 22 are symmetrically provided between the slides 2. The workbench 1 is provided with a continuous pressure structure for continuously applying pressure to the outer wall of the ABR pipe 22. The workbench 1 is provided with an instantaneous pressure structure for applying instantaneous pressure to the outer wall of the ABR pipe 22.
[0026] The raw materials of the ABR pipe 22 described in this embodiment include, by weight, 40-100 parts of polyvinyl chloride, 5-8 parts of chlorinated polyethylene, 3-5 parts of methyl methacrylate-butadiene-styrene ternary graft copolymer, 0.5-2 parts of coupling agent, 1.2-1.8 parts of stabilizer, 0.2-1.0 parts of polyethylene acetic acid, 0.08-0.2 parts of antioxidant, 0.02-0.05 parts of phthalocyanine blue, 0.5-1 parts of titanium dioxide, 0.2-0.8 parts of paraffin, 0.7-1 parts of accelerator, 0.1-0.3 parts of initiator, and 8-20 parts of polymethyl methacrylate; the density of the ABR pipe 22 is 1.35 g / cm 3 .
[0027] The stabilizer consists of a rare earth stabilizer and an organic tin stabilizer, wherein the weight ratio of the rare earth stabilizer to the organic tin stabilizer is 0.2-0.4:1-1.3; the accelerator is a cobalt isooctanoate solution; and the initiator is a butanone peroxide solution or a cumene hydroperoxide solution.
[0028] In this solution, the ABR pipe 22 is fixed to the support 6. The end of the ABR pipe 22 is sealed by sliding the slide 2 and the closing plate 3, and then the slide 2 is locked with a locking pin. At this time, the ABR pipe 22 forms a loop with the liquid storage tank 4 through the hoses 5 at both ends. A pump is used to circulate the liquid between the ABR pipe 22 and the liquid storage tank 4, wherein the liquid contains antifreeze. The ABR pipe 22 is then subjected to continuous pressure or instantaneous pressure by a continuous pressure structure or an instantaneous pressure structure, respectively, to test the various pressure resistance capabilities of the ABR pipe 22 under working conditions. In addition, the ABR pipe 22 can also be tested without liquid in it, thereby more comprehensively testing the performance of the ABR pipe 22. At the same time, this solution can also use temperature control equipment to cool the liquid in the liquid storage tank to test the performance of the ABR pipe 22 at temperatures ranging from room temperature to -10°C.
[0029] In this embodiment, the continuous pressure structure includes two mounting seats 7 symmetrically fixed on the workbench 1, and the facing ends of the mounting seats 7 are provided with hydraulic rods 8 horizontally and perpendicular to the ABR pipe 22, and the ends of the hydraulic rods 8 are fixed with clamping plates 9 whose ends are in contact with the outer wall of the ABR pipe 22. The facing end faces of the clamping plates 9 are coaxially provided with mounting grooves, and rubber bags 12 are fixed between the upper and lower sides of the mounting grooves. The rubber bags 12 are filled with liquid, and the ends of the mounting grooves are provided with telescopic cylinders 10 facing the rubber bags 12, and the ends of the telescopic cylinders 10 are provided with push plates 11 connected to the rubber bags 12; the facing ends of the mounting grooves are provided with semicircular grooves, and the grooves are concentric with the ABR pipe 22. Positioning screws 13 passing through the clamping plates 9 are horizontally threaded on both sides of the grooves, and the facing ends of the positioning screws 13 are provided with baffles 14 slidingly connected to the arc surface of the grooves. The baffles 14 are arc-shaped and coaxial with the clamping plates 9.
[0030] In this solution, after the ABR pipe 22 is installed, the hydraulic rod 8 is controlled to extend, causing the clamping plate 9 to fit against the ABR pipe 22. At this point, a corresponding number of baffles 14 are selected based on the required pressure area of the ABR pipe 22 to be tested. By rotating the positioning screws 13 on the corresponding baffles 14, the baffles 14 are moved away from the baffles 14, exposing the corresponding area of the installation slot. Furthermore, the exposed area of the installation slot can be further adjusted by controlling the movement distance of the baffles 14. The hydraulic cylinder then pushes the baffles 14 to squeeze the rubber bag 12, forcing it to tightly fit against the ABR pipe 22 through the exposed area of the installation slot and continuously applying pressure to the ABR pipe 22. The continuous pressure structure in this solution can apply continuous pressure to different pressure-bearing areas of the ABR pipe 22, thereby more accurately testing the ABR pipe 22's continuous pressure performance.
[0031] In this embodiment, the instantaneous pressure structure includes a gantry 15, a moving block 16 is provided between the two sides of the gantry 15, and electromagnetic acceleration coils are provided on both sides of the gantry 15 to accelerate the moving block 16 (which is a conventional technical means, so it is not described in detail and is not drawn in the figure). A number of guide grooves that pass through the moving block 16 horizontally and vertically are opened inside the moving block 16, and the guide grooves are parallel to the ABR pipe 22. Both ends of the guide groove are slidably provided with a tightening block 17, and the facing end faces of the tightening block 17 are inclined. A number of through grooves are opened at the bottom of the guide groove, and the through grooves are slidably connected with an impact block 18, and an elastic reset member 19 is provided between the impact block 18 and the through groove, and the bottoms of adjacent impact blocks 18 are all abutted against each other.
[0032] In this solution, after the ABR pipe 22 is installed, the corresponding number of abutting blocks 17 at both ends of the guide groove are pushed according to the required pressure area of the ABR pipe 22 test. The inclined end surfaces of the abutting blocks 17 compress the impact blocks 18, causing the corresponding impact blocks 18 to move downward. The impact blocks 18 that have moved downward to their limit position apply instantaneous pressure to the ABR pipe 22, thereby controlling the contact area of the instantaneous pressure structure on the ABR pipe 22. Furthermore, by controlling the movement distance of the abutting blocks 17, and thereby the number of impact blocks 18 that move downward, the contact area of the instantaneous pressure structure on the ABR pipe 22 is further increased. The moving block 16 is then released from a high position, allowing it to fall freely. The impact blocks 18 at the bottom of the moving block 16 apply an instantaneous force to the ABR pipe 22. Furthermore, electromagnetic acceleration coils on both sides of the gantry 15 accelerate the moving block 16, increasing the force applied to the ABR pipe 22. In this solution, the contact area between the instantaneous pressure structure and the ABR pipe 22 is controlled by adjusting the number of impact blocks 18 that move downward, thereby more accurately testing the sustained pressure performance of the ABR pipe 22.
[0033] In this embodiment, the bottom of the impact block 18 is in contact with the outer arc surface of the ABR pipe 22.
[0034] In this embodiment, a reinforcement groove is provided in each of the adjustment grooves along the axis direction of the clamping plate 9 , and a reinforcement rib 20 is integrally formed on the back of each of the baffles 14 to slide in cooperation with the reinforcement groove.
[0035] By providing the reinforcing ribs 20 and the reinforcing grooves, the baffle 14 is guided and the strength of the baffle 14 is enhanced to prevent the baffle 14 from breaking.
[0036] In this embodiment, a rubber pad layer is provided on the surface of the baffle 14 .
[0037] The rubber pad is provided to reduce the additional scratches caused by the baffle 14 to the ABR pipe 22 .
[0038] In this embodiment, a limiting pin 21 for fixing the pressing block 17 is detachably connected to the moving block 16 , and an end of the limiting pin 21 abuts against the pressing block 17 .
[0039] By providing the limiting pin 21 , the stability of the pressing block 17 is enhanced to prevent the pressing block 17 from loosening during the test process.
[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
