Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5 The present invention provides the following technical solution: A performance testing device for concrete preparation includes a testing box 1. The left and right sides of the testing box 1 are respectively provided with a pressure-bearing test tank 2 and a permeability test tank 3. The pressure-bearing test tank 2 is provided with a pressure-bearing test frame 4. The pressure-bearing test frame 4 is provided with a uniform pressure application component 5. The permeability test tank 3 is provided with a dynamic permeability detection component 6. The uniform pressure application component 5 includes four telescopic hydraulic cylinders 51, which are respectively installed at the top inside the pressure test frame 4. A first pressure plate 52 is bolted between the bottoms of the four telescopic hydraulic cylinders 51. A first pressure sensor 53 is bolted to each of the four corners of the bottom of the first pressure plate 52. A second pressure plate 54 is bolted between the bottoms of the four first pressure sensors 53.
[0019] In this embodiment: the concrete specimen is placed in the pressure test frame 4 inside the pressure test tank 2, and the uniform pressure application component 5 is activated to test the pressure performance. The four telescopic hydraulic cylinders 51 in the uniform pressure application component 5 are set at the top inside the pressure test frame 4. When the telescopic hydraulic cylinders 51 are activated, their piston rods extend downward. Since the bottom of the four telescopic hydraulic cylinders 51 is bolted to the first pressure plate 52, the extension of the piston rods drives the first pressure plate 52 to move downward. The first pressure sensors 53 at the four corners of the bottom of the first pressure plate 52 descend synchronously with the first pressure plate 52, and monitor the pressure in real time during the descent. The second pressure plate 54 bolted between the bottoms of the four first pressure sensors 53 applies uniform pressure to the concrete specimen smoothly under the action of the telescopic hydraulic cylinders 51, thereby testing the pressure performance of the concrete specimen. The dynamic permeability detection component 6 inside the permeability test tank 3 tests the concrete's permeability resistance.
[0020] Specifically, such as Figure 4 As shown, the dynamic permeation testing component 6 includes a placement plate 61, which is bolted inside the placement groove. A booster pump 62 and a frequency converter 63 are bolted to the top of the placement plate 61.
[0021] Specifically, such as Figure 4 As shown, a water storage tank 64 is provided on the top right side inside the test box 1. The bottom of the water storage tank 64 is fixedly connected to the top of the booster pump 62, and the bottom of the booster pump 62 is connected to the permeation test box 65.
[0022] Specifically, such as Figure 4 As shown, a placement plate 61 is bolted inside the permeation test tank 3. A booster pump 62 and a frequency converter 63 are bolted to the top of the placement plate 61. The bottom of the water storage tank 64 is fixedly connected to the top of the booster pump 62, and the bottom of the booster pump 62 is connected to the permeation test box 65.
[0023] In this embodiment: Water is injected into the water storage tank 64 located on the top right side of the test chamber 1 through the water inlet pipe 15 on the top right side. A booster pump 62 and a frequency converter 63 are respectively attached to the placement plate 61 bolted inside the permeation test tank 3. The bottom of the water storage tank 64 is fixedly connected to the top of the booster pump 62. The concrete specimen is placed into the permeation test box 65. A sealing gasket 66 is provided at the bottom of the inner wall of the permeation test box 65 to prevent water leakage. The test sample 67 is placed on the sealing gasket 66. The bottoms of the two fixing springs 68 bolted to the top of the permeation test box 65 contact the top of the test sample 67 to ensure stable placement. The booster pump 62 is started, and the water storage tank 64... Water flows from the bottom of the water storage tank 64 into the booster pump 62 under the action of the booster pump 62, and then enters the permeability test box 65 through the pipe connected to the bottom of the booster pump 62 to conduct permeability tests on the concrete specimen. At the same time, the operating parameters of the booster pump 62 can be adjusted by the frequency converter 63 on the top of the placement plate 61 to change the water pressure and flow rate, simulating different water pressure conditions that may exist in actual construction, and realizing dynamic permeability detection. The second pressure sensor 69 bolted to the right side of the inner wall of the permeability test box 65 can monitor the pressure inside the box in real time. The water outlet pipe 610 fixedly connected to the bottom of the permeability test box 65 discharges the permeated water, thereby detecting the permeability resistance of the sample by the amount of water discharged.
[0024] Specifically, such as Figure 3 As shown, a placement seat 7 is bolted to the bottom of the pressure test frame 4, and the top of the placement seat 7 is provided with anti-slip texture 8.
[0025] Specifically, such as Figure 3 As shown, guide rods 9 are slidably provided on both sides, front side and rear side of the top inside the pressure test frame 4. The bottom of the guide rods 9 is bolted to the top of the first pressure plate 52. A controller 10 is bolted to the right side of the top of the pressure test frame 4.
[0026] In this embodiment: the placement seat 7 bolted to the bottom of the pressure test frame 4 provides a stable placement platform for the concrete specimen. The anti-slip texture 8 on the top of the placement seat 7 can prevent the concrete specimen from sliding during the test, ensuring the accuracy of the test. Guide rods 9 are slidably provided on both sides, front side and rear side of the top of the pressure test frame 4. The bottom of the guide rods 9 is bolted to the top of the first pressure plate 52. During the process of the telescopic hydraulic cylinder 51 driving the first pressure plate 52 to move up and down, the guide rods 9 play a guiding role, ensuring that the first pressure plate 52 and the second pressure plate 54 move up and down smoothly, so that the pressure is evenly applied to the concrete specimen. The controller 10 bolted to the top right side of the pressure test frame 4 can control and adjust the entire pressure test process, such as controlling the telescopic speed and pressure of the telescopic hydraulic cylinder 51.
[0027] Specifically, such as Figure 1 , Figure 4, Figure 5 As shown, support feet 11 are bolted to the four corners of the bottom of the test box 1, and anti-slip blocks 12 are bolted to the bottom of the support feet 11. A water receiving hopper 13 is provided on the right side of the bottom of the test box 1. A scale bar 14 is provided inside the water receiving hopper 13. The water receiving hopper 13 is used in conjunction with the water outlet pipe 610.
[0028] Specifically, such as Figure 4 , Figure 1 As shown, a water inlet pipe 15 is provided on the right side of the top of the test box 1. The bottom of the water inlet pipe 15 is fixedly connected to the water storage tank 64. A first test door 16 and a second test door 17 are respectively provided on the front side of the test box 1. A control panel 18 is bolted to the front side of the first test door 16.
[0029] In this embodiment: support feet 11 are bolted to the four corners of the bottom of the test box 1. Anti-slip blocks 12 bolted to the bottom of the support feet 11 can increase the friction between the device and the ground and ensure the stability of the device during operation. When performing dynamic permeation testing, excess water in the permeation test box 65 will flow into the water collection hopper 13 set on the bottom right side of the test box 1 through the water outlet pipe 610. The scale strip 14 set inside the water collection hopper 13 can make it easy for the staff to observe the amount of water collected, thereby understanding the permeation of the concrete specimen. The water inlet pipe 15 set on the top right side of the test box 1 is used to inject water into the water storage tank 64. The first test door 16 and the second test door 17 are respectively set on the front side of the test box 1, which makes it easy for the staff to put the concrete specimen into the pressure test tank 2 and the permeation test tank 3. The control panel 18 bolted to the front of the first test door 16 allows the staff to operate and control the entire test device, such as starting and stopping the test program and setting test parameters.
[0030] Working principle: Workers place concrete specimens into the pressure-bearing test frame 4 in the pressure-bearing test tank 2 and the permeability test box 65 in the permeability test tank 3 through the first test door 16 and the second test door 17 on the front of the test box 1, respectively. During pressure performance testing, the uniform pressure application component 5 is activated. The piston rods of the four telescopic hydraulic cylinders 51 at the top inside the pressure-bearing test frame 4 extend downwards, causing the first pressure plate 52, which is bolted to its bottom, to move downwards. The first pressure sensors 53 at the four corners of the bottom of the first pressure plate 52 descend synchronously and monitor the pressure in real time. The second pressure plate 54, bolted to the bottom of the four first pressure sensors 53, smoothly applies uniform pressure to the concrete specimen placed on the anti-slip textured seat 7. The guide rod 9 at the top inside the pressure-bearing test frame 4 guides the movement of the first pressure plate 52. The controller 10 on the right side of the top of the pressure-bearing test frame 4 controls the extension speed and pressure of the telescopic hydraulic cylinders 51. Regarding permeability performance testing… Water is injected into the water storage tank 64 through the water inlet pipe 15 on the top right side of the test box 1. The booster pump 62 on the placement plate 61 is started. The water in the water storage tank 64 enters the permeation test box 65 through the pipe via the booster pump 62 to conduct permeation tests on the concrete specimen. The operating parameters of the booster pump 62 can be adjusted by the frequency converter 63 on the placement plate 61 to change the water pressure and flow rate, simulating the environment of different water pressures that may exist in actual construction, thereby realizing dynamic detection. The second pressure sensor 69 in the permeation test box 65 monitors the pressure inside the box in real time. The permeated water is discharged from the outlet pipe 610 to the water receiving hopper 13. The permeation status of the concrete specimen can be understood through the scale strip 14 in the water receiving hopper 13. In addition, the support feet 11 and anti-slip blocks 12 at the four corners of the bottom of the test box 1 ensure the stable operation of the device. The control panel 18 on the front side of the first test door 16 allows the staff to operate and control the entire test device, such as starting and stopping the test program and setting test parameters.
